What is the reason for the cracking of metal stamping parts? -Hardware

If the mold master assembles the mold when the process is wrong or the product material shopping guide buys inferior materials, it may cause the metal stamping parts to tear. The problem is not difficult to solve the problem that the shopping guide buys inferior materials and causes the metal stamping parts to tear. The easy way is to return the material directly and change the material supplier. 1. Disadvantages of flanging forming mold planning. The mold is shared by the left and right parts of a mold with two cavities. Because the content of this process is not only flanging, but also shape forming content. In addition, the parts are particularly messy, the curved surface is narrow, and the forming requires concave die pressing. The matching of the core and the forming surface results in a large forming stroke of the mold structure condition, a small blank area, and a cracking phenomenon. 2. The performance of the stamping oil is not satisfactory. The process requires stamping oil to isolate the mold and the workpiece during the stamping process. However, the use of non-special oils such as rapeseed oil, machine oil, and recycled oil will cause unqualified performance in the stamping process. During the process, the oil film breaks instantly to form workpiece scratches, burrs and burrs. In severe cases, problems such as workpiece cracking and mold damage will occur. 3. Part of the tensile stress is too large. Due to the excessive tensile stress during the processing, the metal stamping parts are affected by internal stress and external impact, resulting in large bulging deformation and cracking. Fourth, the forming process parameters are not fulfilled in place. In the process of forming parts, the process requires that the die, the blanking core and the two parts must be tightly bonded together. When the slide of the machine tool slides down, the plastic deformation of the sheet is forced to complete the forming. The processing technicians did not specify according to the process. It is required to adjust the pressure of the machine tool in time at this stage, the operation is unstable, and the stamping parts are cracked. Hardware-The product accuracy reaches 0.01MM, the daily output is 3 million punching times, and the mold can be produced in 4 days. Strictly abide by the confidentiality agreement.
