Deep drawing parts/stretch straight wall cracking broken how to deal with?

Deep drawing parts/stretch common in our daily life, as some of the technology and equipment products cover, etc. , that we are in the production of deep drawing parts, may encounter straight wall cracking broken broken phenomenon, how do we handle? The author and everyone to discuss. Usually pull on the surface of the deep broke usually would be the height of the drawing is too big, we can adopt the method of reduce deep drawing height to adjust the mould, can increase the deep drawing of plastic process to adjust, but using this method you must first rule out the possibility of other problems. Second deep drawing parts, pull broken may be the mould blank-holder force is too large, raised face light, pressure side can be reduced at the same time to ensure that the edge of deep drawing parts not wrinkle; Also can check the tensile mold problems, in the production of stamping parts to ensure the smoothness and accuracy of the mold surface, cannot have scratches and die core shift, punch and die of parallelism and perpendicularity to ensure good, adjust the appropriate clearance, avoid the gap is too small lead to break down, check before production, avoid deep drawing parts damage; We also need to pay attention to control the raw material of the deep drawing parts, when drawing strength is not enough or does not meet the requirements for the deep drawing of material surface and thickness, we should change in time. Co. , LTD. , dongguan city, the main production of various kinds of stamping parts, stretching pieces, metal assembly parts and other metal mechanical parts. Company mainly on technical strength, in the production of precision machinery parts, household appliances parts, auto parts and other industries in the success of the production and management experience, the company has passed ISO9001:2015 quality system certification. The factory now has 2 ~ 315 tons punch more than 60, more than 30 Taiwan mold machining equipment, and another lathe, grinding machine, milling machine, shearing machine, welding machine, spot welding machine and other supporting facilities. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
