5 Steps You Need To Know About Installing Punch Dies
In the stamping work, the punching machine needs to work with the punching dies. So that we can complete various tasks and punch out various products. Therefore, the molds play an important role in the stamping process. The staff should have a certain understanding of the punch molds installation, so they will produce products with high efficiency.
So, how should the molds be installed on the punching machine? The following are the 5 steps to install them:
1) Before installation, it should be confirmed that the cutting edge of the die is sharp. It means that there is no collapse on the cutting edge of the concave die, and there is no missing angle of the punch die. If there is a crack or missing corner, please sharpen the edge of the knife firstly.
2) Before closing the dies, the operator needs to put a silicon steel sheet between the upper and lower dies. So that the operator can prevent the cutting edges from being injured due to the handling process.
3) Before installing the mold on the punch, the operator should clean burr and the garbage with the cloth. If there is burr or garbage on the upper and lower plane of the mold, it will cause the punching sheet burr to be out of line.
4) Adjust the slide stroke to the appropriate position to press the upper die. It is necessary to fit the die handle or die frame plane closely to the bottom surface of the slide block. Then the operator has to press and the screw of the lower molding plate gently.
Then, adjust the slider upward to remove the silicon steel sheet in the middle. Loose the lower molded plate screw, adjust the slider downward until the punch enters the die 3 ~ 4mm, and press the lower molded plate screw.
When we work to punch with a new die, the punch must enter the die 3 ~ 4mm, otherwise, there will be punch collapse or die swelling crack.
5) Raise the slider to the top of the dead point, adjust the punch rod stop screw, until the tightness is appropriate. Then idling several times to observe whether the mold and punch parts work normally. If there are no exceptions, you can start production.
The installation of the punch die is related to the accuracy of the punching accuracy. Therefore, the operator should take every step seriously and eliminate hidden troubles in time. Please click https://www.harsle.com/Punching-Machine.html for more punching information!
