Punch forming device capable of guaranteeing material strap to be stable and free of deformation

The invention relates to the technical field of crystal packaging shell production, in particular to a punch forming device capable of ensuring that a material belt is stable and does not deform. In the using process, when each stamping head retracts, the positioning surface can tightly press the material belt on the horizontal working surface, so that the material belt can be effectively prevented from being pulled up, the transition section of the material belt is prevented from being pulled and bent, the flatness of the material belt in the stamping process can be kept, and the stamping work is smoothly carried out. 本发明涉及晶体封装壳生产技术领域，具体是一种保证料带平稳不变形的冲压成型装置。本发明在使用的过程中，当各个冲压头回缩时，定位面能够将料带压紧在水平工作面上，进而能够有效地避免的料带被拉起，避免料带的过渡段处出现牵拉弯折，从而能够保持料带在冲压过程中的平整性，进而使冲压工作顺利地进行。
