YCK-200T four-column down pressure hydraulic press customer operation training course

YCK-200T-G hydraulic press is a new fast hydraulic press introduced by Hongde Company, featuring fast speed and high precision. This tutorial is intended for on-the-job training for customers when they purchase a new machine. First, the basic knowledge of the machine: 1. Outline size (length × width × height): 1200mm × 960mm × 2000mm 2, the whole machine weight: 2.5 tons 3, machine motor power: 7.5KW - recommended power supply line is 6mm2 4, cooler cooling water interface size and cooling water flow: interface size ZG3 / 4"; cooling water maximum flow: 60L / min, cooler water flow must not exceed this value. 5. The machine must be connected to the cooling water during operation to ensure the normal oil temperature (oil temperature ≤ 55 ° C). Second, the basic functions of the machine: 1. The machine has a fast and fast approach to the workpiece and a fast return function, which greatly improves the efficiency of the machine. 2. The machine also has the function of top and bottom feeding, which is suitable for the pressing process of the workpiece under various conditions. Third, the operation of the machine: 1. Start the motor (note the motor steering - clockwise direction), the operator can select the "jog" or "automatic" mode according to the production needs. When the “jog” mode is selected, the jog mode is entered, and the corresponding jog button is pressed to implement the text function of the button. When the button is released, the position is automatically stopped before the release. Therefore, the jog button is generally used when installing the mold for debugging. When the "Auto" mode is selected, the machine enters the semi-automatic cycle state and stops when an action cycle is completed. Top material selection, select "Off", then the top material does not work, select "Upper top material" to work on the top material, and select "Lower top material" to work under the top material. 2. In normal production, the operator only needs to press the double button. Fourth, the simple adjustment of the machine: The handles of the hydraulic devices on the machine have been adjusted at the factory, and it is not necessary to adjust them during normal production. In order to avoid abnormal movements, even machine accidents. Normal production only needs to adjust the pressure relay and the pressure limiting relief valve on the right front of the machine. 1. Adjustment of pressure relay: The pressure relay is to adjust the pressing pressure in production. The pressure relay is clockwise to increase. The increase value can be read in the pressure gauge. When the pressure reaches 25MPa, the master cylinder has reached 200T pressure. It can't be adjusted any more, otherwise it will be overloaded. 2. Adjustment of the pressure limiting relief valve on the right front of the machine: firstly relax the relief valve, adjust the pressure relay to the required pressure (Note: not overload), then press the automatic double button to make the machine automatically descend. Pressing to work, the pressure relay can't send at this time (that is, the master cylinder can't automatically go up). Then slowly adjust the relief valve handle to adjust the pressure set by the pressure relay (ie, the pressure relay can just send the signal to the end, finally relax the pressure relay, and lock the nut of the relief valve, the adjustment is over. After the adjustment, the mold will never be crushed due to overpressure, so that the mold can be better protected. Five, common faults and solutions: a, the machine movable beam slides: 1. Adjust the support valve and slowly tighten the handle clockwise until the movable beam does not slip. 2. If the adjustment support valve does not work, adjust the lift relief valve. 3. If the adjustment support valve and the lift relief valve do not work, the support valve and the lift relief valve should be removed and cleaned, and then the manifold block should be replaced. 4. If the support valve and the lift relief valve still do not work after cleaning, check the main piston seal for aging and wear. b, the master cylinder can not be lifted: 1. Check whether the electromagnetic spill valve of the system is normal, whether the relief valve is normal, and whether the filling valve is open. 2. Check whether the reading of the master cylinder pressure gauge reaches the pressure set by the pressure relay. If the master cylinder pressure does not reach the pressure set by the pressure relay, the master cylinder will not return when the semi-automatic state is reached. 3. Check whether the main solenoid valve is in the lifting direction of the master cylinder; if there is a stuck valve phenomenon, if the valve is found, remove the valve core and clean the valve core and valve body with diesel oil, and then reinstall it. 4. Determine if the draft force of the mold exceeds the lifting force of the master cylinder. c. There is no pressure or insufficient pressure in the master cylinder: 1. Check whether the

1. The hydraulic machine operator must be trained to master the equipment performance and operation technology before it can work independently. 2, before the operation, should first clean all kinds of debris on the mold, wipe off any dirt on the hydraulic machine rod. 3. The hydraulic machine installation mold must be carried out under the condition of power failure. It is forbidden to collide the start button, handle and pedal on the foot switch. 4. Install the upper and lower molds to the center, adjust the mold gap, do not allow the single side to deviate from the center, and confirm that the mold is tested again after fixing. 5. Before starting the hydraulic machine, first start the equipment to idle for 5 minutes. At the same time, check whether the oil level of the fuel tank is sufficient, whether the sound of the oil pump is normal, whether the hydraulic unit and the pipeline, joints and pistons are leaking. 6. Start the equipment pressure test to check whether the pressure reaches the working pressure, whether the equipment action is normal and reliable, and whether there is leakage. 7. Adjust the working pressure, but should not exceed 90% of the rated pressure of the equipment, test a piece of workpiece, and then produce after passing the inspection. 8. For different hydraulic machine profiles and workpieces, when pressing and calibrating, adjust the working pressure and pressure, pressure keeping times and time of the press at any time, and ensure that the mold and workpiece are not damaged. 9. When the body is pressed down on the plate, it is strictly forbidden to extend the hand and the head into the working part of the platen and the mold. 10. It is strictly forbidden to tap, stretch, weld, bend, twist and other work at the same time as pressure. 11. Do not smoke, weld, or ignite around the hydraulic press. Do not store flammable or explosive materials. Take fire prevention measures. 12. After the hydraulic machine is working, the power supply should be cut off, the hydraulic machine column rod should be wiped clean, the lubricating oil should be added, and the mold and workpiece should be cleaned and placed neatly.

Hydraulic machine tool structure, simple, economical and practical Advantages of press: (1) Computer optimized structural design, machine tool structure, simple, economical and practical. (2) Hydraulic control adopts the integrated system of cartridge valve, which has reliable action, long service life and small hydraulic impact, which reduces the connection pipeline and leakage point. (3) Independent electrical control system, reliable operation, objective action and convenient maintenance. (4) Adopt button centralized control, with three modes of operation: adjustment, manual and semi-automatic. (5) Through the operation panel selection, two forming processes of fixed range and constant pressure can be realized, and the pressure holding delay is realized.
