Optional devices for punching machine
In order to realize the fully automatic control of the punching machine, hydraulic and pneumatic auxiliary devices should be equipped except to the electrical control. The hydraulic system and pneumatic system should be compact, reliable, and easy to control and adjust. They work similarly but have little difference in the scope.
Auxiliary devices include leveling device, automatic feeding, lubrication, scrap cutting and removal, discharge of parts and residue, safety protection for mold, lubrication device, etc.
Lubrication system
The lubrication system of the punching machine is mainly used for the machine guideway, transmission gears, ball screws, and spindle parts. in the form of electric intermittent lubrication oil pumps and quantitative centralized lubrication oil pumps. Electric intermittent lubricating pumps are used more frequently. The automatic intermittent time and the amount of pumping can be adjusted according to the requirements or parameters. The filter in the lubricating pump needs to be cleaned and replaced regularly. Generally, it should be replaced once a year.
Cooling system
The cooling system is mainly used to cool the tool and the workpiece during the cutting process, and also can wash the punching chips. In order to obtain a better cooling effect, cutting fluid is pumped out through a nozzle in front of the tool holder or spindle, and directly into the cutting heat part of the tool and workpiece. The start and stop of the cooling pump are controlled by the auxiliary instructions in the CNC program.
Chip removal device
In order to smooth the automatic processing of the punch and reduce the heat of the punching machine, it is necessary to equip a chip removal device. The cutting fluid is often mixed with the chip, and the chip removal device should separate the chips from it and send them to the chip collection box, and the cutting fluid is recovered to the cutting fluid box.
Chip removal device is an accessory with independent function. The structure and working form of the chip removal device of the CNC punch should be selected according to the type, specifications, processing characteristics, the material of the workpiece, and the type of cutting fluid used. Common chip evacuation devices include flat chain chip evacuation devices, self-plate chip evacuation devices, and spiral chip evacuation devices.
