1. Receive a die cutting die
In the production process, after we have finished matching the materials, we need to receive the die to install the knife. Then, when we receive the die in the first step, we need to receive the die according to the drawings and material numbers. In the process of receiving the die, we must remember that we need to correctly compare the material number and tool number in order to receive the tool correctly, not just by the shape of the product.
There are too many products with similar shapes in large die-cutting factories. At the same time, there are several new and old sets of tools used for the same product. Once the wrong tool is obtained, it will be found during production, which has caused a great waste of materials.
2. Fixed die cutting die
After receiving, we need to fix the received die on the template of the die cutting machine. When fixing here, we need to strictly compare the operation instructions to confirm whether the die is a lower punching or an upper punching die.
If it is the upper punching die, it needs to be fixed on the lower template, and if it is the lower punching die, it needs to be fixed on the upper template. When fixing, we usually use thin double-sided tape for fixing. When choosing double-sided tape, remember to use double-sided tape with high viscosity and good stability (usually 3M tape) to prevent the die from falling off during the punching process.
3. Angle adjustment of fixed die
When fixing the die, it is not only necessary to fix the tool, we must ensure the verticality of the die and the feeding direction of the machine during the fixing process, and ensure that the die is kept perpendicular to the feeding belt during punching. state.
4. Fixing of die cutting backing plate
After fixing the mold, we need to fix the backing plate. The main function of the backing plate is to protect the direct contact between the blade and the template, reduce the damage of the tool and improve the service life of the tool. The backing board is generally made of PVC board or PE insulation board with a thickness of about 1mm. The general use area of ​​the backing plate should be larger than 5mm on each of the four sides of the tool base plate. It is advisable to fix the backing plate on one side of the template in the feeding direction.
Some die-cutting masters are used to pad two pads when starting up, mainly for the convenience of adjustment.
