Solutions to common problems with high-speed punching machines

The clearance of the high speed punching die set is small, and the total clearance of the high speed precision punching machine of the general Han Jian mold sleeve is 20% and 25% of the raw material thickness. The bump alignment is not good, including the mold base, the guide die part, the numerical control punching machine sleeve is not accurate enough, etc. The overheating of the high speed punching machine is mainly due to the overheating of the punch caused by long-term same-die rolling. Poor grinding of the mold sleeve will cause quenching and die sleeve wear. Part of the side punching machine, such as step punching machine, angle punching machine or cutting, the side force of aluminum door and window parts will make the punch on one side, and the gap on this side will be reduced, resulting in more serious wear of the mold sleeve. If the installation accuracy of the CNC lathe die set is not high, the punch will be more seriously offset from the lower die, resulting in the destruction of the punch and the die sleeve. The scrap edge rebound will be caused by the mold, and its related elements: the larger the white balance of the die edge, the larger the arc of the edge, and the more likely it is to cause the waste edge to rebound. Enter the module of the mold set, the modulus of the high-speed punch into the upper part of each small punching machine is a certain number, and the modulus of the mold set is small, which is very easy to cause the waste to rebound.

Avoid mold sleeve stripping: use a high-speed milling machine special type of male mold to prevent hair loss. Aluminum door and window spare parts. The mold sleeve is often sharpened and demagnetized. Boost the integrated IC gap. Replace the flat edge die with a circular arc N-die. The mold set installs the mold machine. Effectively improve the mold sleeve channel modulus. In areas where tissue cloth is very easy to hole, the amount of wear on the mold sleeve is not the same, and some parts are scratched and wear quickly, especially on the narrow rectangular frame mold sleeve. The key reason for this problem: the design of the high-speed punching machine CNC punching machine is not accurate enough or the production and processing accuracy is not enough, mainly because the mold seat of the upper and lower rotary table is not aligned. The design scheme or accuracy of the mold set does not meet the regulations. The accuracy of the stamping die guide sleeve is insufficient. The mold set gap is poorly selected. In order to avoid inconsistent wear of the mold sleeve, it should be regularly maintained and adjusted with a safety rod and the alignment of the tool table and the CNC lathe mounting seat.
