Mould manufacturing cost and quality of life is to affect the cost of metal stamping parts and an important factor.
Mold design and manufacturing needs more time, it will extend the new metal stamping parts production preparation time.
The design principle of metal stamping parts: 1, dongguan hardware stamping parts must meet the product use and technical performance, and can be convenient for assembly and replacement.
2, metal stamping parts must be beneficial to improve the utilization rate of metal materials, reduce material varieties and specifications, as far as possible to reduce the consumption of materials.
In the permission of using cheap materials, as far as possible make the parts do not waste and waste less cutting.
3, metal stamping parts must be simple shape, reasonable structure, to help simplify the mould structure, simplify the process number, 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, metal stamping parts, in the guarantee can be normal use, make dimensional precision grade and the surface roughness request lower grade, and promotes the exchange of products, reduce scrap, guarantee the stability of product quality.
5, metal stamping parts, as far as possible should be conducive to use of existing equipment, process equipment and technological process for machining, and is helpful to extend the service life of die.
The precision of the mould and structure directly affect the forming of dongguan metal stamping parts and precision.
Mold base, frame, guide the standardization and development of simple dies (
For small batch production)
Progressive die, compound die, transfer (
For mass production)
, as well as the development of quick die change equipment, can reduce metal stamping parts production preparation workload and shorten the preparation time, can make the suitable for mass production of advanced punching technology reasonably applied to small batch more varieties of production.
