Experience in metal stamping die design

Stamping die, also known as stamping die, metal die, metal stamping die, the meaning is almost the same. It refers to the pressure processing method of using the mold fixed in the punch or press to exert certain pressure on the metal or non-metallic sheet, so that the material can be separated or formed, so as to obtain certain size requirements and qualified appearance quality parts. Metal stamping manufacturers are divided into many kinds of die. Today is mainly for the familiar metal stamping die.

By mould processing of products, size, appearance is basic and same, it's not a big difference, because can rapid prototyping, high production efficiency, product quality is stable, the precision meets the requirements, high material utilization, simple operation, low labor intensity of workers, the technical requirements of operating workers is not high, average person just came in, followed the others learn operation for a day or two, will soon be able to get started, Some even take a day or two to learn in a few minutes. If it is the host hand of the production line, it is necessary to learn to operate the punch, the feeding machine, the leveling machine, the mold frame and so on. These are some very simple jobs. It is necessary to have strength and bear hardships.

Usually pay attention to safety don't put any mold inside things inside, wrench, scissors, and other tools such as don't put inside the mold, mold repair to repair after mold (professional term: mold repair), you will like before, to see if they forget things inside the mold, general mold repair is, of course, won't make such a mistake, but you also need to pay attention to. Don't break the mold, or the body where the hand hurts, do this remember to pay attention to safety, accidentally forget to take out the mold inside, punch down is likely to break the mold, in case things fly out? People can get hurt.

Sometimes when the fork mold of the forklift truck is not well forked, the mold falls off. At this time, don't help it with your hand and let it be far away. It's okay if the mold is broken, don't hit people. When the crane is lifting the mold, we should also pay attention to the distance from the mold. It is not good to be careful that the mold shakes and hits it.

Mould this line, or dealing with mould is often prone to accidents, new people into the factory should pay special attention to these safety matters.

The structure of the stamping die is introduced

The structure of the stamping die, the structure of the punching die, the structure of the die is much the same, according to the characteristics of different products and needs to design the corresponding die, different die structure, its function is also different, the production of products are different, in general, there are simple, complex. But no matter how complex the structure, its basic structure is the same, is nothing more than a number of templates, blocks and standard parts.

The mold is generally composed of a number of templates and parts (we call it into the block, or into the child) and standard parts assembled.

The general stamping die structure, the specific template from top to bottom (including code number) is:

The template of the upper mold is:

Upper supporting plate, upper foot, upper die base (UPU), upper backing plate (UBU), upper splint (PHU) stop plate (PPS), stripper plate (PSU);

​the templates for the lower die are:

Lower formwork (DIE), lower backing plate (LBD), lower DIE base (LPD), lower backing foot, lower supporting plate;

​other less commonly used templates:

Upper cover plate (CVU), strike plate, upper template, lower stripper, lower stop plate, lower splint, male mold, female mold, etc.;

​some mold parts are:

Upper die into the child, into the block: splint into the block, stripper into the block, punch, etc.

The lower die into the son, into the block: the lower die into the block, the lower die knife edge, etc.;

​standard parts: spring, hex screw, stop payment screw, wire spring, contour sleeve, guide column, guide sleeve, contour sleeve gasket, dual purpose pin, top material pin, etc.;

​non-standard parts: external positioning, internal positioning, pitch positioning, external limit column, internal limit column, etc.;

★ Stamping die number

The stamping die number is usually written like this (for example):​

Engineering model: 90-KNMF0125RAH, 90-KNMF0125RAA, 90-KNMF0125RBB

Continuous mode: 90-KNMF0125SAA, 90-KNMF0125SBB

In the rear RAH, R represents engineering model, and H represents a total of eight sets (from A-H, RAH, RBH...... RHH), A stands for first set; ​rAA or RBB stands for riveting die, such as riveting stud, riveting shrapnel, etc.

The S in SAA and SBB stands for continuous mold, 0125 stands for mold number, and the F in front stands for year. When the mold is produced in a year, the number of the mold is used to describe it, such as F0125 and G0125. If F stands for 2010, then the mold F0125 produced in 2010 can be referred to as: 125 mold, and then the mold produced in 2011 begins with G. At this time, if you say 125 mold, most people think it is G0125 mold.

Other such as on the splint (PHU), the number is 90-KNMF0125SAAPHU, splint into the block 90-KNMF0125SAAPHPA001;

​if the continuous module has two sections, then A and B are used after the number of 90-KNMF0125SAAPHU, then the splint of the first section should be 90-KNMF0125SAAPhua, the second section 90-KNMF0125SAaphub, Splint into 90-KNMF0125SAAPHPA001, 90-KNMF0125SAAPHPB001;

​lower template (DIE): 90-KNMF0125SAadie, 90-KNMF0125RahDIE

As for other numbers, which are not explained here, a brief explanation is given:

A complete set of stamping die structure from top to bottom should be:

A "-" indicates that the number is not commonly or rarely used.​
