(1) Get the die cutting tool die
In the process of consumption operation, we need to pick up the tool mould and stop loading the tool after matching the data. Then when we pick up the tool mould in the first step, we need to stop picking up the tool mould according to the drawing and material number. In the process of picking up the tool mould, we must remember to correctly compare the material number and tool number, so that the tool can be picked up correctly, not just by the product shape. There are too many products with similar shapes in large die-cutting processing plants, and there are several sets of new and old tools used in the same product. Once the wrong tool is received, it will be found when the consumption is stopped, which has formed a large waste of data.
(2) Fixed die cutting tool die
After receiving, we need to fix the received knife mold on the template of the die-cutting machine. At the fixed time here, we need to strictly compare and confirm the operation instructions to understand whether the die is lower blanking or upper blanking. If the upper punching die is fixed on the lower template, if the lower punching die is fixed on the upper template. When fixing, we usually use ****** high and thin double-sided adhesive to stop fixing. When selecting double-sided adhesive tape, remember to use double-sided adhesive tape with high viscosity and good stability (usually 3M adhesive tape) to avoid fragmentation of the knife die during the punching process.
(3) Angle adjustment of fixed tool die
When fixing the tool die, it is not just necessary to fix the tool. During the fixing process, we must ensure the perpendicularity of the tool die and the feeding direction of the machine table, and ensure that the die is perpendicular to the feeding belt during punching.
(4) Fixation of base plate for die-cutting processing
After fixing the mold, we need to fix the base plate. The main function of the base plate is to maintain the direct contact between the blade and the template, reduce the damage of the tool and improve the service life of the tool. The base plate is generally made of PVC plate or PE insulation plate with a thickness of about 1mm. The common use area of the base plate should be more than 5mm on each side of the tool base plate. The base plate shall be fixed on the formwork at one side of the feeding direction.
Some die-cutting masters learn two pads of air cushion when starting up, mainly for convenience conditioning.
(5) Adjustment of die-cutting pressure
The pressure conditioning here mainly refers to the conditioning of the depth of the die-cutting die seat. After we install the tool, we need to stop the mold base conditioning and pressure test to check whether the mold can effectively punch the data. In the process of pressure conditioning, it is strictly prohibited to directly stop single action or linkage punching. It is necessary to adjust the equipment to the manual gear to stop the test conditioning. When the die base is adjusted to the current stroke and still fails to effectively cut the data, stop the pressure conditioning and retest. When the die seat is adjusted to the stroke and has been punched to the lower die seat, it is clarified that the die seat pressure is too deep, and the pressure should be reduced to retest.
