Sheet Metal: 9 Things You Need to Know When Operating Punching Machine

When it comes to sheet metal processing, mechanical equipment is inseparable. When the mechanical equipment is running, we must first ensure safe operation. The punching of sheet metal must strictly implement the operating procedures to prevent accidents. We ensure personal safety, equipment safety and stable product quality.


1. Learn more about punching machine


The operator should learn the structure and functions of the machine, know the operating procedures and precautions. They start with the simplest things. After that, they can be responsible for more.


2. Protective measures


When working, operator should wear labor protection equipment correctly. Clear away debris in the workplace at first. Only after other people leave the working area can the power be turned on. Before starting the machine, check whether the protective safety equipment is normal and whether the transmission, connection, lubrication and other parts are secure. The screws for installing the mold must be firm and must not move.


Check whether the moving parts of the punch press (such as guide rails, bearings, etc.) are filled with lubricating oil. The punch machine should be idle for 1-3 minutes before operation. Check whether the flywheel operation is stable. Check the flexibility of the clutch, brake and other control equipment. When everything is done, start the machine.


3. Check the punching force


Check the punching force, and avoid overload operation. When the machine is running, it is forbidden to put hands into the slider area. When adjusting or repairing the machine tool, turn off the power and hang a "No Operation" warning sign.


4. Interrupt operation


When disassembling and assembling the mold, taking materials, and inspecting the mold, turn off the power first, and the punching machine should stop working. First, find the correct equipment mold according to the sample or drawing, put it into the mold cavity, and align the upper and lower molds to ensure the correct position.


Gradually tighten the mold and lock the mold, which must be firm and secure. Do not start the machine before adjusting it. After the equipment adjustment is completed, ensure that the mold is in good condition before working.


5. Feeding and punching


After the punching machine is started, one operator carries out the feeding and punching. Others are not allowed to press the electric keys or step on the foot switch board, and they are not allowed to put their hands in the punch machine operating area. During a single punching operation, do not keep feet on the pedals. After each punching, immediately disengage from the pedals to prevent accidents.


6. Inspection criteria


When punching, the operator should stand appropriately, keep a certain distance between the hands and head and the machine. Pay attention to the punch movement at all times. Chatting, joking, looking around and talking on the phone are prohibited. Items must be placed strictly according to needs and must not be placed randomly.


Strict inspection rules have been established during the production process. All the first punching parts must be inspected. Compare the samples to see if the mold is correct or damaged. Check whether the product has white edges, rough edges, tooth edges, or debris stuck on the mold. For the indentation, the die should be continuously discharged to see if there are any continuous parts. Check whether the positioning is appropriate.


For printed products, check whether the area around the waste material is even and whether the area around the text and pictures is even and symmetrical. Check whether the window and light hole are in the middle according to the shell. Only after passing the inspection can it be put into production.


7. Punching short and long workpieces


When punching short workpieces, special tools such as pliers, hooks, tweezers, and clamps should be used correctly. Do not feed or pick up parts directly by hand. When punching long parts, a safety support rack should be installed, or other safety measures should be taken to avoid digging injuries.


8. Correct errors promptly


It is necessary to check the condition of the mold equipment in time. If there is any looseness or slippage, it should be adjusted in time. If abnormal sounds and structural malfunctions of the punch are found during operation, the power should be turned off immediately for inspection. When disassembling the mold, it is necessary to do it in the closed state.


9. End of work


After finishing the work, turn off the power in time, remove the mold, wipe it clean, spray it with anti-rust oil, and place it on the mold base according to the number. Turn off the main power supply after get off work, and close the power supply box.
