Among these factors, the structure of tool is through improving, can buckle it under the prerequisite of effectively releasing pin root stress, improves manual operation efficiency at present, and the components and parts shaping of military industry is accomplished by the manual work, and the uniformity is poor, and the damage rate is high, and the human cost is not trivial, and production efficiency is also relatively low. However, the plastic package device forming equipment which is directly purchased cannot be applied to the production of the glass insulator device, and high cost is caused due to small batch and multiple types of devices, so that high cost investment is avoided.
