Design principle of precision metal stamping parts

Precision metal stamping parts design principle: the design of the stamping parts must be simple shape, reasonable structure, in order to help simplify the mould structure, simplify the process, which is the least, the most simple stamping process to complete the entire parts processing, reduce processing with other methods, and is advantageous to the stamping operations, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity.

(1) the designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.Design principle of precision metal stamping parts

(2) the designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible.Use cheap materials where possible to make parts as scrap free and less scrap blanking.

(3) the design of the stamping parts must be simple shape, reasonable structure, in order to help simplify the mould structure, simplify the process, which is the least, the most simple stamping process to complete the entire parts processing, reduce processing with other methods, and is advantageous to the stamping operations, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity.

(4) the designed stamping parts, in the case of normal use, try to make the size accuracy level and surface roughness level requirements lower, and is conducive to the exchange of products, reduce waste, to ensure the stability of product quality.

(5) the designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow as far as possible to process them, and be conducive to the extension of the service life of the die.

Advantages of metal stamping continuous die:

1. Adapt to the demand of mass production

Continuous die production speed (up to 1000 times/min) is higher than any other operation and processing mode.If the number of presses per minute with the crankshaft press, the daily output can reach 30000~150000 pieces.

2. Engineering arrangement is relatively easy

This kind of mould is properly decomposed into simple shapes and arranged in different workstations, which can avoid the fragile parts of the mould construction and increase the life span of the mould to over 100 million times.

3. Economic

The processing of continuous punching die can save processing materials. The step spacing of the die is 0.8MIN, and the maximum utilization rate of the material is improved.At the same time can reduce the operation management, handling and other artificial and site occupied area, so it is economic.

4, ease the extension processing materials work hardening

The drawing rate can be increased and the number of drawing times can be increased when drawing processing is carried out in the continuous die, so as to reduce the degree of hardening and avoid the need of annealing of semi-finished products.

5. Operation safety

Continuous die is an automatic die, which does not need manual operation and has no possibility of harming human body.When the feeder failure or other accidents occur, the punch can immediately stop action, to avoid damage to the punch.
