As one of the die-cutting equipment in the post press processing of corrugated cardboard boxes, circular die cutting machines have been increasingly valued by cardboard box companies in recent years. In terms of the scope of die-cutting, there are currently no more than three methods used in China, namely circular die cutting, flat die cutting, and circular die cutting. Next, we will focus on discussing the debugging and maintenance of circular die-cutting tools.
gap adjustment
Maintaining the correct tool clearance is the key to ensuring die-cutting quality and maintaining tool life. When other components are in normal use, our company's method for adjusting the clearance of die-cutting circular die-cutting tools is as follows.
1. Use imported carbon paper to adjust the gap between the cutting edge and the bottom roller of the cutting tool, as the thickness of domestic carbon paper is generally uneven. To ensure the accuracy of gap adjustment, imported carbon paper should be used as much as possible. The adjustment standard is based on the fact that the imported copy paper can just be cut open. If it is completely cut through, the cutting edge of the die-cutting knife on the upper roller may touch the bottom roller.
2. It is required that the gap between the blade line and the blade roller meet the above requirements. If the gap is too large, a thin steel sheet with a thickness of 0.003mm must be used to adjust it one by one; If the gap is too small, professional tools can be used to grind the die-cutting knife appropriately.
Adjustment and maintenance
Proper adjustment and maintenance of the die-cutting circular die-cutting tool in advance can prolong its service life. The specific plan is to stop the machine, remove the tool, and inspect, adjust, and maintain it when the die-cutting circular die-cutting tool runs for about 1 million revolutions (depending on the actual production situation). Experimental results have shown that this scheme not only ensures the die-cutting quality of the product, but also guarantees the service life of the pressure circular die-cutting tool.
During the adjustment and maintenance period of the die-cutting tool, spare tools can be put into use. However, it should be noted that the actual usage time (operating speed) of all die-cutting and circular die-cutting tools should be staggered to avoid these tools reaching the repair or scrap time at the same time, which may affect normal production.
