Characteristics of precision stamping
Precision stamping is a kind of fine blanking with powerful blank holder. Its technological principle is: on a three action press, with the aid of a fine blanking die with special structure, under the action of strong force, the material will produce plastic shear deformation, so as to obtain high-quality precision stamping parts.
Precision stamping has the following characteristics:
1) Precision stamping consists of three forces (blanking force, blank holder force and counter jacking force). The blanking clearance between punch and die is only 0.5% of the material thickness, which is 1 / 10 of the common stamping clearance.
2) Precision stamping has the advantages of smooth blanking surface, high dimensional accuracy and high flatness. After deburring, assembly can be carried out directly without cutting, chipping, grinding and leveling other processing procedures required by common stamping, which saves a lot of investment in auxiliary equipment, manpower, material resources, operation costs, etc., which not only improves the production efficiency, but also avoids the precision loss of each process, and ensures the repeated precision and production reliability of mass production parts.
3) The main application field of precision stamping is automobile parts. Modern car industry enjoys all the performance advantages of fine blanking parts. There are at least 40 kinds of fine blanking parts in each car. According to this trend, Heju stamping devotes itself to precision stamping parts of automobile, mainly automobile wiring harness and wiring terminal. The material is usually C2680, the spacing is 6.5mm, the dimensional tolerance is ± 0.02mm, the straightness is + / – 0.05mm, the perpendicularity is + / – 0.05mm, and the stamping speed is 500spm / min. Automotive precision stamping parts have passed TS16949 certification, accept OEM / ODM, welcome to order.
