As the national plan to expand domestic demand, especially the policy effect of the adjustment and revitalization plan of key industries, has begun to appear, Climbing frame punching machine The production growth of the mechanical equipment industry is prominent, and the month on month growth rate has increased, initially entering the recovery stage. The gradual improvement of demand and the continuous maintenance of low prices of main raw materials will enhance the profitability of enterprises, and the profit situation of the industry will be further improved. Punching machine The industry has good prospects.
Combined punching machine and mechanical section punching machine combine punching, with advantages of light weight, small volume, low noise, etc., and are ideal equipment for modern machinery manufacturing industry such as metallurgy, bridge, communication, power and other industries.
1、 Pre preparation before startup
1. The lubrication of each transmission part shall be sufficient, and each lubrication point shall be refueled 2-3 times per shift; Shearing tools and punching dies shall be intact, free from cracking, and firmly fastened;
2. The clearance between the punch and the hole wall of the lower die shall be uniform, meeting the punching requirements. The punch to the lower configuration shall slightly exceed the hole plane of the lower die; The electrical insulation and grounding of the equipment are good.
2、 Operation steps and specifications
objective
Ensure the normal and safe operation of the punching machine, ensure the personal safety of the equipment operator, and meet the production needs.
1. Operation steps
1) Check Rack punching machine Power supply, stable voltage, no phase loss, leakage protector and air switch in good condition. Wiring: open the junction cabinet of the combined punching machine, connect the wires and close the cabinet door.
2) After power on, step down the foot switch, the machine does not act, swap the power lines, and check whether the emergency stop switch is turned on.
3) When working, pay attention to turning off the power every time the mold is changed.
4) After the work is completed, turn off the switch, turn off the main power switch, unplug the power cord, and clean the debris.
2. Safe operation specification
1) Punching and shearing of steel plate, round steel, square steel and section steel can be carried out simultaneously. However, it is not allowed to cut two kinds of steel at the same time.
2) It is strictly prohibited to shear hardened steel and process beyond the equipment capacity.
3) The cutting tool and cutting edge should be kept sharp, and should be replaced in time if the cutting edge becomes blunt or cracks. The steel plate, round steel, square steel and section steel must be compressed when shearing.
4) When shearing or punching, it is strictly prohibited to touch the surface of the processed workpiece, measure the workpiece, and clean the leftover materials directly by hand.
5) When the operator leaves the machine tool, he must stop the machine. When he starts again, he must check that the original position of the handles at each part is unchanged.
6) It is not allowed to shear laminated sheets, narrow sheets and short sheets that cannot be pressed tightly.
7) When feeding, the fingers must be 200 mm away from the knife edge, and special tools should be used for small parts.
