Abstract

The invention provides a stamping device used for forming spike heads. The stamping device comprises a base provided with a supporting table face and two supporting legs. The supporting legs are arranged on two sides of the supporting table face horizontally arranged. A horizontal stamping table surface is fixed between the supporting legs. A vertical positioning groove is formed in the middle of the upper surface of the stamping table face. A guide hole is formed in the supporting table face and corresponds to the positioning groove. A stamping rod penetrates the guide hole. The lower end of the stamping rod is provided with a stamping head, and the upper end of the stamping rod extends out of the guide hole to be fixed with an end plate. Two V-shaped connecting rods and a boss which is arranged on the stamping table face are further provided. The V-shaped connecting rods are symmetrically arranged relative to a center axis of the stamping rod. Driven ends of the V-shaped connecting rods are all abutted against the end plate. The V-shaped connecting rods are hinged with pins at V-shaped corners. The pins are symmetrically arranged on the boss. Driving ends of the V-shaped connecting rods are hinged to piston rods of two cylinders.

Description

technical field [0001] The invention relates to stamping technology, in particular to a stamping device for forming the head of a spike. Background technique [0002] Spikes are divided into railway spikes and road spikes. Railway spikes have a flat head and are usually formed by cold heading or stamping. The existing stamping device used for the head of the road stud generally uses the piston rod of the cylinder to drive the punch to punch directly, and the punching force is relatively high at one time. After stamping, the head of the road stud often has defects such as damage, cracks or scars. The quality of part molding is low. Contents of the invention [0003] The invention provides a stamping device capable of improving the forming quality of the spike head. [0004] The present invention scheme is as follows: [0005] A stamping device for forming the head of a spike, including a base, the base includes a horizontal support platform and two legs arranged on bot...
