Speaker net manufacturer: double-sided tape die-cutting process
1. Receive die-cutting die
During the production process, after we have prepared the materials, we need to receive the mold and stop installing the tool. Then, when we receive the mold in the first step, we need to stop receiving the mold according to the drawing and material number. In the process of accepting molds, we must remember that we need to correctly compare the material number and tool number, so that the tool can be accepted correctly, not just the product shape. There are too many products with similar shapes in large die-cutting factories. At the same time, multiple sets of old and new tools are used in the same product. Once the wrong tool is taken, it will be discovered when the production is stopped, resulting in a huge waste of materials.
2. Fixed die-cutting die
After receiving it, we need to fix the received mold on the template of the die-cutting machine. After the time here is fixed, we need to confirm strictly against the operation manual to know whether the mold is a lower die or an upper die. If the upper punch needs to be fixed on the lower template, if it is the lower punch, it needs to be fixed on the upper template. When fixing, we usually use double-sided tape with a larger diameter and thinner thickness 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 mold from falling off during the punching process.
3. Angle adjustment of fixed mold
When fixing the mold, not only the tool must be fixed, but also the perpendicularity between the mold and the feeding direction of the machine must be ensured during the fixing process, and the mold and the feed belt must be perpendicular to each other during punching.
4. Fixing of die-cut backing plate
After fixing the mold, we need to fix the backing plate. The main function of the backing plate is to maintain the direct contact between the blade and the template, reduce the damage of the tool and increase the service life of the tool. The backboard is generally made of PVC board or PE insulation board with a thickness of about 1mm. The general application area of the backing plate should be more than 5mm on each of the four sides of the tool base. It is recommended to fix the backing plate on one side of the formwork feed direction.
Some die-cutting masters are used to using two pads when starting the machine, mainly for convenience.
5. Adjustment of die-cutting pressure
The adjustment of the pressure here mainly refers to the adjustment of the depth of the die-cutting die holder. After we have installed the tool, we need to stop the mold base adjustment and pressure test to check whether the mold can punch the material effectively. During the pressure adjustment process, it is strictly forbidden to directly stop the single-action or linkage punching, and the equipment must be adjusted to the manual gear for testing and adjustment. When the mold base is adjusted to the current stroke and still cannot punch material effectively, stop the pressure adjustment and re-test. When the mold base is adjusted to the stroke and rushes to the lower mold base, it means that the pressure of the mold base is too deep, and the pressure should be lowered and re-tested.
