.32.4 When adjusting the mold or overhaul, the power supply must be turned off to ensure safety;
2.4.4工 should clean the machine tool, clean up the surrounding working area, and put the workpiece in the specified position.
3.Use the operating steps
3.1 Order of boot button
① Rotate the electric control box key switch clockwise; press the electric control box white power switch (white switch bright); press the green start button (green start button bright); press the front panel with green circle start button; press the foot switch left pedal "up" lift the upper pedal (the higher the pedal); put the bend into the bend mold groove; start bending (parameter set according to the material bending pressure sheet)
3.2 Bend, take and cleaning
① step on the right pedal "down" of the foot switch to bend; step on the left pedal "up" to lift the upper module, remove the workpiece; press the red button to stop operation, press the green start button; close the electric box switch button, then dial the key switch counterclockwise to "0" for power off; clean the equipment.
In case of emergency or emergency like abnormal noise, jam and smoke during operation, stop the equipment operation immediately by pressing the emergency stop switch button (the operating lever, control panel and electric control box are closed according to the nearest principle), turn off all equipment switches and report to the equipment management personnel; when the emergency stop switch occurs, cut off the power immediately after turning off, maintain the site and report to the leader.
5.Equipment maintenance and maintenance
5.1 Mechanical lubrication
Lubricate the rear gear and the torsion shaft of the main rail mechanical retaining adjustment device as required. The lubricant adopts N46 industrial lubricant, No.2 calcium-based or lithium-based grease, as shown in Fig. 8 (diagram of lubrication parts of machinery).
.15.1 Rear gear: straight guide rail (2), wire (2), require grease once with oil gun; bearing (4) once every June;
5.1.2 rails are rectangular rails (2) with lubricant injection 1-2 times a week.
5.1.3 gear adjustment device: worm reducer replaces lubricating oil once every December; block limit wire applies lubricating oil once every June, and bearing (4 places) injects grease once every June.
5.1.4force axis: at rotating shaft 4 of middle connecting plate, 2 axes at both ends, inject grease once for each shift.

5.2 Maintenance and maintenance of the hydraulic system
5.2.1 pressurized oil replacement
Regularly check the cleanliness and deterioration of the oil. The cleanliness of oil should be checked regularly quarterly. If the oil turbidity, flocculation, discoloration and odor, stop immediately and replace the oil. The sampling oil is obtained from the oil discharge valve, and the water shall be removed first after sampling. The abandoned hydraulic oil should be properly treated so as not to pollute the environment.In general, the hydraulic oil shall be replaced within half a year after the initial use of the machine tool, and it must be filtered once a year later. In principle, the use period of the hydraulic oil shall not exceed 18 months. The replacement of oil must be replaced at one time, with no residual oil inside the fuel tank. The tank must be carefully cleaned before rerefueling, and when any element related to the hydraulic system is removed, the connection position must be cleaned. N32~N46 anti-wear hydraulic oil is about 500 liters. Specific requirements for oil replacement are as follows:
1. Strictly clean the fuel tank before refueling. It is strictly prohibited to use cotton yarn or cotton cloth for cleaning. Silk cloth or edible flour ball is recommended
2 Refueling must be done through the filter refueling truck of less than 5 μ, and through the air filter oil inlet on the fuel tank cover plate (unscrew the filter cover by hand);
3 When refueling, the height of the fuel tank level should be in the middle and upper position of the level gauge, but not below or beyond the indicated range of the level gauge. During the commissioning, attention should be paid to observe the change of the height of the oil surface. Once lower than the lowest position of the level gauge, the car must be stopped and then the hydraulic oil is added.
10℃5.2.2严 grid control oil temperature, when the oil temperature is lower, heating measures or empty car circulation shall be taken. Cooling measures or shutdown shall be taken when the oil temperature exceeds that.60℃
Check the leakage of valve, valve plate and pipeline in phase 5.2.3定, and replace the sealing ring in time.
When the 5.2.4在 overhaul oil pump needs to release the oil in the oil tank, open the stop valve at the bottom of the oil tank to release the oil. When regularly check the cleanliness of the oil fluid, remove the water in the oil tank from the valve.
1, overhaul any part of the hydraulic system, must be conducted by skilled personnel after a complete understanding of its principles and performance;
2 The maximum operating pressure of the hydraulic system is 26 MPa.If the working pressure exceeds the rated or maximum pressure, it can damage the mechanical parts and cause irreparable damage. This parameter has been adjusted at the factory, so random adjustment is not allowed.
3. When repairing any part of the hydraulic system, the slider must be completely placed in the lower mode groove, and then the lower chamber pressure is zero;
4 The electric oil pump must be turned off during overhaul.
The 5, pressure gauge shall be frequently checked and replaced immediately if oil leakage or damage is found. The pressure gauge must be checked once within a year to be used after it is qualified. When the pressure gauge must be removed, the pressure gauge reading must be zero.
