four,
Electro-hydraulic punching machine
Main structure and working principle:
The main frame of the machine, hydraulic system level electrical system and so on.
1,
Rack section:
Mainly composed of beams, columns, trays, cylinders, casings, bases, etc.
2,
Hydraulic system:
It consists of hydraulic pump, switching valve, fuel tank, oil filter, oil pipe and joint.
The hydraulic pump is an axial piston high-pressure pump with a flow rate of 2.5m3/min and a rated pressure of 31.5Mpa. It is directly driven by a 1500KW three-phase motor and fixed on the base.
The switching valve is mounted on the right side of the front panel and is operated by the manual lever. Lift the cylinder up, press down on the cylinder, and stop in the middle.
The relief valve is located inside the casing. The relief valve is used to adjust the pressure range. This program has been debugged before leaving the factory and cannot be adjusted freely.

Instructions:
1,
Before use, first fill the fuel tank with 6L hydraulic oil (open the rear cover to refuel), check whether the fasteners of various oil pipe joint boxes are moving, if it is loose, tighten it to prevent oil leakage, affect the use, check the electrical system. Ground, fuse is valid.
2,
Operating procedures and methods:
At the beginning, put the manual lever to the middle stop position, then press the start button on the panel to turn on the power, and the oil pump starts to work; move the manual lever to raise the piston for a certain distance, observe the abnormal phenomenon such as stuck, if any, side stop Check and eliminate. If there is no abnormality, the piston should be raised for a certain distance and then lowered. This way, the air in the cylinder is exhausted several times to observe the air bubbles in the oil pipe and can be used normally.

maintenance
1,
The inside and outside of the instrument should be kept clean to prevent rusting of various parts.
2,
Always check whether the oil is clean or not. According to the usage, the hydraulic oil in the fuel tank should be settled once a month. The hydraulic oil should be replaced once every six months. When changing the oil, the oil tank and oil filter should be thoroughly cleaned. If the oil is turbid, it can not be seriously When used, it should be replaced immediately, otherwise it will accelerate the wear of various parts of the hydraulic system and even affect the normal work.
The hydraulic oil specifications and temperature are recommended as follows:
(1)
When the ambient temperature is 1
GB443-84N46 (equivalent to No. 30 mechanical oil) at 5±5°C
(2)
When the ambient temperature is 25±5°C, use GB443-84N68 (equivalent to No. 40 hydraulic oil)
Seven,

Precautions:
1,
It is strictly forbidden to add oil to make the oil pump idle.
2,
The air in the system must be drained before use to use.
3,
The stamping test piece should pay attention to the rising distance of the cylinder. It is strictly forbidden to contact the piston with the test piece to prevent damage to the machine. The operator should pay special attention.
4,
When the test is done, the piston should be lowered to the bottom to prevent the piston from rusting and causing rust.
5,
You must read the instruction manual before testing the machine.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The last SCSI device in the SCSI chain uses a terminator, and the intermediate device does not need a terminator. Once the terminator is used by the intermediate device, the SCSI card cannot find the future SCSI device. If the last device does not use a terminator, SCSI will not work properly. Terminator is composed of resistors, located at the end of the SCSI bus, to reduce the mutual influence of the signal, maintain the constant voltage on the SCSI chain.
Most of the SCSI devices have built-in terminators and use a jumper to control on / off. The SCSI device is highly intelligent and can automatically control the terminator on / off. For example, if a hard disk is connected to a CD-ROM, the CD-ROM can work normally regardless of whether the terminator of the hard disk is on or off. However, when two hard disks are connected, the situation becomes more complicated. Before two Seagate hard disks are connected, one hard disk terminator must be off. Before a Seagate hard disk is connected to a quantum hard disk, a hard disk terminator can work normally regardless of whether it is on or off.
