Flat head clamping screw head upsetting device

Abstract

A flat head clamping screw head upsetting device comprises a lower die fixing plate, a hexagon socket head cap screw A, a lower forming die, an upper forming die, a return spring, a hexagon socket head cap screws B, a mounting blocking plate, a workpiece positioning plate, a hexagon socket head cap screw C, an adjustable blocking plate, a guide plate, a hexagon socket head cap screws D and an ejector spring. The lower forming die is arranged on the lower die fixing plate through the hexagon socket head cap screw A. The mounting blocking plate is arranged on the lower forming die through the hexagon socket head cap screw B. The guide plate is arranged on the lower die fixing plate through the hexagon socket head cap screw D. The return spring is arranged between the workpiece positioning plate and the lower die fixing plate and disposed in the lower forming die. The adjustable blocking plate is arranged on the workpiece positioning plate through the hexagon socket head cap screw C and provided with two blind holes. The ejector spring is arranged in the blind holes. The upper forming die is arranged above the lower forming die.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to an upsetting device for the head of a flat-head clip screw. Background technique [0002] Due to its light weight, easy installation and use, clamps are widely used in industry, agriculture, science and technology, aerospace and other product fields. Products in industry, agriculture, science and technology, aerospace, etc. are usually controlled automatically by pneumatic and hydraulic control systems. All are rigidly connected with metal pipe fittings, and some parts must be flexibly connected with rubber pipe fittings. After the rubber pipe is set on the metal pipe joint of the controller, in order to prevent the rubber pipe from falling off or leaking when it is under the pressure of gas or liquid, the rubber pipe should be fastened with a clamp, and the screw on the clamp should be fastened with a safety wire. To prevent the screw from loosening due to vibration dur...

Problems solved by technology

This processing method requires about 0.0625Kg of material, and the clamp screw adopts the upsetting method to process the blank, which requires about 0.0081 Kg of material. Compared with the two processing methods, the turning processing method not only has low production efficiency, but also has a low utilization rate of the material blank. 13%
