III. Four-column hydraulic press common faults and maintenance methods four-column hydraulic press common faults and maintenance methods: In winter and worse working conditions, four-column hydraulic press system to check, maintenance, often change the working oil. Great attention should be paid to the storage and transportation of the working oil of four-column hydraulic press. The oil drums shall be marked and covered. In winter, do not pay attention to the air condensed into water and oil, do not rust the barrel into the rust pieces. In winter, the four-column hydraulic engine and other mechanical systems to take a number of preventive measures, such as covering anti-freezing, heating and heat preservation, the use of low viscosity oil, etc. , are applicable to the hydraulic system. In the four-column hydraulic press Hydraulic drive system, are some of the more sophisticated parts. Although people feel labor-saving and convenient to the hydraulic transmission of four-column hydraulic press, they also feel that it is easy to be damaged. The main reason is that the working principle and structure characteristics of four-column hydraulic press are not clear. Hydraulic systems have three basic "disease-causing" factors: pollution, overheating, and entering the air. These three disadvantages are closely interrelated, and the occurrence of any one of them will be associated with the emergence of another problem or problems. By practice, 75% of the hydraulic system "pathogenic" reasons, are caused by these three. 1. The working oil of the four-column hydraulic press is spoiled because of entering the dirt 2. Overheating 3. Entering the air solution: the Cleaning and assembly of some major precision parts in the four-column hydraulic press system should be carried out in a very clean room, indoor should have clean floor and airtight door window, the temperature had better keep in 200C or so. IV. Four-column hydraulic press common general maintenance method four-column hydraulic press common general maintenance method (1) four-column hydraulic press action failure electrical wiring is not firm or wrong connection check electrical (2) four-column hydraulic press slipper crawl 1 system accumulated air or pump suction 2 precision adjustment or column Oil 1 check whether the pump suction pipe is in air or not, then move up and down several times and add oil on the 2 columns, readjust the accuracy (3) when the sliders of the four-column hydraulic press descend slowly, the pressure supporting force is too large to adjust the back pressure valve so that the upper chamber of the upper cylinder does not have pressure, the maximum is not more than 1 MPA, four-column hydraulic press after stopping the slide block under serious 1 CYLINDER MOUTH SEAL RING leakage pressure valve adjustment pressure is too small or pressure mouth is not strict 1 watch cylinder mouth, SEND OIL AND GAS 2 adjust pressure check valve mouth 5. Pressure gauge needle of four-column hydraulic press swings badly 1 pressure gauge oil circuit has air 2 pipeline mechanical vibration pressure gauge damage 1 slightly loosen the pipe joint when the pressure is up, 2 deflates the pipe 2 fastens the pipe 3 replace the pressure Gauge 6. Four-column hydraulic press high pressure travel speed is not enough, up pressure slow 1 high pressure pump flow regulation too small 2 pump wear or burn 3 system leakage serious 1 according to the pump manual adjustment, pUMP ECCENTRICITY can be adjusted to 5 bar 2 at 25 MPA. The pressure drop of four-column hydraulic press is too fast when keeping pressure 1. The valves involved in keeping pressure are not strict or the pipeline is leaking 2. The sealing ring in the cylinder is damaged 1. Check the filling valve, the sealing research of the pressure-keeping Relief Valve 2. Replace the sealing ring 8. The utility model relates to a screw four-column hydraulic press, which belongs to the field of hydraulic press, in particular to a hydraulic press with screw drive, the task of which is to provide a transmission device, the main nut thread is forced only when the slide block presses the workpiece, and the main nut is not pushed by the hydraulic cylinder during the non-pressing workpiece stroke of the slide block, so that the lubricating oil is filled into the screw bearing surface. The screw Rod is located at the center axis of the machine body and is mounted on the machine body through the bearing. The upper end of the screw rod is connected with the inertia wheel, the main nut is matched with the lower part of the screw Rod, and is connected with the main slide block through the main flange The auxiliary nut is matched with the middle part of the screw Rod, and is connected with the auxiliary slide block through the auxiliary flange. The guide rail is mounted symmetrically in a central axis in the screw four-column hydraulic press, and the main slide block and the auxiliary slide block are slidily connected along the Guide Rail, the end of the Piston Rod of the hydraulic cylinder is hinged with the auxiliary sliding block, which can improve the lubrication condition of the nut and screw and prolong the service life of the screw four-column hydraulic press. About the hydraulic station of four-column Hydraulic Press: The working principle of the hydraulic station of four-column hydraulic press is as follows: the motor drives the oil pump to rotate, the pump draws oil from the oil tank, converts the Mechanical Energy into the hydraulic oil pressure energy, the hydraulic oil is transmitted to the hydraulic machinery's cylinder or motor through the external pipeline after the direction, pressure and flow are adjusted by the hydraulic valve through the Integrated Block (or valve combination) , it controls the change of direction, force and speed of hydraulic motor, and drives all kinds of hydraulic machinery.
Four-column hydraulic press hydraulic station also known as hydraulic pump station, is an independent hydraulic device. It provides oil according to the requirements of the main engine, and controls the direction, pressure and flow of oil flow. It is suitable for the main engine and hydraulic equipment can be separated on a variety of four-column hydraulic press. As long as the user purchase the press station and the host on the executive body (cylinder or motor) connected with the tubing, hydraulic machinery can achieve a variety of specified action, working cycle. The hydraulic station of the four-column hydraulic press is composed of a pump device, a manifold or a valve combination, a fuel tank and an electrical box. The functions of each component are as follows: The pump device is equipped with a motor and an oil pump, which is the power source of the hydraulic station of the four-column Hydraulic Press and converts the Mechanical Energy into the pressure energy of the hydraulic oil. Manifold block-is composed of hydraulic valve and Channel Body. It can adjust the direction, pressure and flow of the hydraulic oil. Valve assembly-is a plate valve mounted on a vertical plate, connected to the pipe behind the plate, with the same function as the manifold block. TANK-A semi-closed, plate-welded vessel with a filter air filter, etc. . It is used for storage, cooling and filtration of oil. Electrical box-in two forms. One is a Terminal Board with external leads; the other is equipped with a complete set of control appliances. Four column Hydraulic Press Pressure is small what reason: 1. Is the oil in the cylinder of the four-column hydraulic press dirty? 2. Are you holding it in? Pressure activated? 3. Four-column hydraulic time long, loose parts with, internal leakage? 1, four-column hydraulic pump wear serious, large internal leakage. 2. Relief Valve malfunctions and is normally open. 3. Directional valve internal leakage is large. 4, four-column hydraulic machine implementation of the original leakage inside the large, small pump pressure. The application of four-column hydraulic forming technology four-column hydraulic forming technology has a wide range of applications in automobile, aviation, aerospace and pipeline industries, the hydraulic forming technology of four-column hydraulic press is mainly applicable to the hollow structure with round, rectangular or special section which varies along the component axis, such as the special-shaped pipe fittings of automobile exhaust system, the hollow frame with non-circular section, such as engine bracket, instrument panel bracket, body frame (about 11% ~ 15% of the vehicle mass) , hollow shaft parts and complex pipe fittings. The suitable materials for four-column hydraulic forming process include carbon steel, stainless steel, aluminum alloy, copper alloy and nickel alloy. In principle, the materials suitable for cold forming are all suitable for four-column hydraulic forming process. Four-column hydraulic system four-column hydraulic press is the use of hydraulic transmission technology for pressure processing equipment, can be used to complete a variety of forging and pressure forming process. For example, steel forging, metal structural parts of the molding, plastic products and rubber products, and so on. Four-column hydraulic press is one of the earliest machines to use hydraulic transmission. At present, hydraulic transmission has become the main transmission form of pressure processing machinery. Four-column hydraulic press in Heavy Machinery Manufacturing, aviation industry, plastic and Non-ferrous metal processing industries, four-column hydraulic press has become an important equipment. On the four-column hydraulic press non-pressure problem: Q: four-column hydraulic press does not rise, starting up switch has 10MM action, rise after non-pressure, sliding work, how is it? Answer: Check the four-column hydraulic pump outlet pressure, control system pressure, whether the support valve is stuck. The Piston slipping is related to the insufficient supporting force of the lower chamber, and the non-pressure keeping may be the leakage of the relief valve of the four-column hydraulic press. Four-column hydraulic press system is relatively simple, do not consider overhauling too much trouble. The difference between four-column hydraulic press and pneumatic press the difference between four-column hydraulic press and pneumatic press the pneumatic press has noise, small force, easy maintenance will not leak oil; four-column hydraulic press quiet, strong, slightly more complex maintenance. It's all about the APP. The steel workshop noise is already quite big, may not consider the noise factor. If the force requirements are relatively large, then choose four-column hydraulic press. If, the force requirement is not so big (50kg or less) the barometric pressure is good, is also cheap. The drawing cylinder of the four-column hydraulic press adopts fast cylinder, the speed can reach 280 mm / s, the drawing force can reach 1000 KN, the blank holding force can reach 800 Kn, and the speed and pressure can be adjusted in the prescribed range, users can choose the best drawing speed and blank holder force according to their needs, and can draw out all kinds of products such as high quality stainless steel, which is the ideal equipment for sheet metal drawing. The oil supply system of the Hydraulic Chamber of the four-column hydraulic press is required to meet the technical requirements of hydraulic forming, and the system is not too complicated. Its action as follows: Motor start, pump to oil by the reversing valve flow back to the oil tank, pump unloading. When 1DT power, oil through the valve, one-way valve into the oil plate will be pressed into the Matrix and forming. At the end of the forming, 1DT POWER CUT, 2DT power, oil into the oil injection through the supercharger cylinder, under the action of ultra-high pressure, the sheet metal further close to the concave die to form its small round corner. The key of the hydraulic system of the four-column hydraulic press is frequency converter 5 and supercharger cylinder 10. In the process of hydraulic forming, the working flow and pressure provided to the hydraulic chamber by the hydraulic system should be constantly changing according to the requirements of the process, therefore, the power consumed by the hydraulic system should also be changing with the change of the working flow and pressure. Describe the General Mechanical Theory of pressure transfer before proceeding to analyze the phenomenon of pressure shock and to rationalize the fluid equation. It is necessary to transport the liquid between two energy sources by taking part in this result about valve positioning at a longer point with little friction in the pipeline. The valve is connected to the same downstream pipe section as to the upstream pipe section. The pressure impingement flow will be passed between the two lines through the valve operation, assuming that the valve closing speed should not be applied to the solid circle theory. If the valve is closed and the flow of the liquid is in the opposite direction, it moves slowly, resulting in the compression of the liquid and the expansion of the cross section of the pipe. The increased pressure in the valve causes the high-pressure liquid to flow in reverse, extending the time it takes for the liquid to flow through the pipe to the valve. The flow of this high-pressure liquid similar to the propagation of sound, is dependent on the liquid and pipe materials as a medium. Similarly, a delay in the downstream flow of the valve will result in a reduction in pressure at the valve. This result denies that the flow of a high pressure liquid is along a downstream pipe, preventing the flow of the liquid, assuming that the fluid pressure in the downstream pipe does not reduce the fluid pressure or the vapor pressure or the pressure released by the dissolved gas, the considerations of willingness are different. Thus, the closed valve causes the flow of high-pressure fluid to flow along the pipe, although those flows have various symptoms. The flow of pressure relative to the stability of the valve through the open pipe. This effect is related to the liquid flow delay between the two cross-sections of the pipe, the pipe itself is affected due to the reverse high pressure liquid, pipe wall expansion. At the same time, the downstream pipe is shortened and the large cross-section deformation of the pipe due to the reduced pressure flowing through the liquid is due to the pipe material and can be demonstrated. For example, use thin-walled rubber tubing. The high-pressure liquid moves along the flow. It has been proved that the velocity of the liquid is close to that of sound due to the tension flow of the liquid along the pipe wall. In this piping material, however, this is a secondary role, and when it is recognized that its presence can explain part of the pressure transfer time as the valve closes, it has little effect on the application of pressure standards in pressure impact phenomena. After the valve is closed, the time of compression will depend primarily on the system boundary conditions, which will be easily illustrated in a number of charts to depict the results of the valve closure on the same system, what happens to the pipeline at each time period. Since the valve closure is instantaneous, a valve with liquid close to each pipe section will bring the valve to a stop, and high-pressure fluid flow may have already passed through each pipe section. At the appropriate velocity C and at time t, the liquid has passed a distance of 1 ct, and in each segment, the Cross section of the pipe is deformed at a distance of 1. The time for the high pressure liquid to reach the storage station is t 1 / C, and an unstable position appears in this distance, which is at the junction of the pipeline and the storage station. Since it is not possible to have laminar flow at the junction of the stations, the maintaining pressure and other values flow through each station before the valve is closed.
