Metal stamping tensile common problems during production, how to solve?

Metal stamping tensile) can be seen everywhere in our daily life, are using stretch forming process of stamping equipment, such as life common glass, cans, automobile parts, etc. , stretch processing again, when mass production is relatively easy to appear what problem? How do we solve? Small authors take you know about the metal stamping tensile strain on the surface of the problem, is mainly due to the heat treatment hardness is low, degree of finish is poor, die corner wear, incorrect process is unreasonable, lack of lubrication and other factors, the size and shape of stretching a discrepancy is usually positioning are not allowed to cause, in addition to adopt measures to reduce springback and to improve the reliability of positioning. At the same time, when the production hardware tensile pieces might crack of bending, a possible reason is that the tensile plastic materials is poor, small bending radius, poor quality of pickling, mould lubrication degree is not enough, the friction is bigger, the material of super thick and other reasons, Metal stamping tensile) in the case of the above question, how can we solve? Need to stretch of stamping parts for many times, on the premise of ensure the appearance quality, internal and external surface can occur in the process of stretch marks, processing shape should be brief and symmetry, as far as possible one-time forming, stretch marks cannot be together the inside and outside of the scale of the scale, the interval of bottom and ACTS on the side of hole to the side wall to be appropriate, the radius around the bottom and wall of moderation. While trying out die summing up experience, and gradually achieve the required size. Dongguan co. , LTD. , founded in 2004, is located in dongguan city, the provincial economic development zone, plant a total area of 15000 square meters, existing staff of 60 people, engineer number 15 people.
