▶ Understanding the tool mold
There are more than 100 kinds of knives in terms of blade angle, hardness of blade and blade, grain of blade and surface processing technology of blade and blade.
The development and production of tool mould is based on the deep understanding of customer’s product demand information and material. The information that customers want to express is presented on the design drawing, so we should review the drawings first, transform the customer’s requirements into their own process flow and the presentation of the final product.
Design of production process requires engineers to have a considerable understanding of materials. Another important factor is to have a good understanding of the performance of the machines of our company. It can be said that understanding materials and understanding the production performance of machines are the basic skills that engineers must have.
Know what the customers want, know the properties of materials, associate the production performance of our machines, and construct the scene of production in mind. How to solve the problems? The solution is the technological process you design, and the tool mold is an important tool to turn what you think into reality. Can it be achieved
▶ Laser knife mould
High depth ablation of knife template is carried out by using the strong energy of laser, so as to achieve the purpose of installing cutter.
What is QDC mould?
The QDC die adopts the mode of module combination, uses the engraving knife die or the corrosion knife die to install in the hardware die base for punching and cleaning; because the die can be quickly replaced according to different die cutting needs, taking into account the advantages of the tool die and the accuracy and stability of the die.
Comparison of the actual drawings of various knife dies: (Japan, general, mirror treatment) different materials need different blades to achieve the most expensive effect. There are also knife mold, material, elastic sponge cushion of the three are also very important. Some materials will produce dimensional variation after die cutting. To make a good tool die, it is also necessary for the tool mold factory to have an understanding of the characteristics of the material, and then formulate the corresponding processing technology.
▶ Processing and manufacturing of tool mould
We take the manufacturing process of the etching die as an example to understand the processing and manufacturing of the tool mold
Process flow of etching die
1 .order receiving
The receiving department is responsible for receiving customers’ e-mails and communicating with customers on production requirements, quotation and delivery time. After the customer’s confirmation, the mold production sheet will be opened and the typesetting will be started. Finally, the drawing will be made into a special film for corrosion, which will be submitted to the corrosion department together with the work order.
After receiving the film and work order, the corrosion department confirms the plate thickness, knife height and material type, and then pastes the film, prints and exposes it. Finally, the prototype of the mould is shown after the liquid medicine treatment. If the exposure work is not done well, it is necessary to repair the figure before entering the corrosion machine for corrosion. After meeting the requirements, it can be taken out. After washing off the coke deposit, it can be sent to the next department. The corrosion department is a rough processing department for the mold.
After receiving rough machining, the engraving department puts it into the machine for processing after visual inspection and confirmation. Due to the difference of die size, difficulty and length of tool line, the production time is different. Generally, the tool mold takes 1-4 hours, and the special tool mold needs 8 hours or even more than 24 hours to complete CNC machining. After the completion of the inspection, the team leader can be sent to QC after it is preliminarily determined that there is no problem.
QC is responsible for the inspection of die size, tool edge, etc., and is responsible for making inspection report, and then sent to heat treatment.
5. according to the customer punching material is divided into two processing methods
If the material does not contain adhesive, it can be treated by general heat treatment. In addition to heat treatment to increase hardness, the self-adhesive material should also be plated with Teflon. Teflon can make the punching products not stick to the die, but due to the special process, the coating of Teflon will not affect the sharpness of the die. After the inspection report is sealed by the supervisor, the die can be packed and shipped.
6. mirror treatment
This treatment can remove the micro grain on the side of the knife edge of the die, achieve the mirror effect, and effectively solve the problem of burr and dust when the product is punching and drawing, and make the product edge smooth and smooth. It is suitable for punching and cutting products with high requirements. At present, our company belongs to the mirror knife and belongs to the exclusive manufacturer in mainland China.
