Knife back forming machine

Abstract

The invention discloses a knife back forming machine, which comprises an upper die, a lower die, a fixed side die, a movable side die, a main hydraulic device and an auxiliary hydraulic device, wherein the main hydraulic device and the auxiliary hydraulic device are fixed on a base; the upper die is fixed on a plunger end of the main hydraulic device; the bottom shape of the upper die is adaptive to the shape required by the top of the knife back; the lower die is fixed on the base; a knife edge slot used for fixing a knife is arranged above the lower die; the fixed side die is fixed on the base; the movable side die is fixed on a plunger end of the auxiliary hydraulic device; and the combined shape of the opposite surfaces of the fixed side die and the movable side die is adaptive to the required shaped by the cross section of the knife. According to the knife back forming machine disclosed by the invention, a purpose of thickening the knife back can be realized, and the knife back forming machine is regular and beautiful in forming. When the knife back forming machine disclosed by the invention is adopted, the knife back of the knife can be processed within 10 seconds, no coal needs to be fired, the energy is saved, the environment is protected, the production efficiency is improved, the labor intensity is lowered, and the production cost is lowered.

Description

technical field [0001] The invention relates to a tool processing device, in particular to a knife back forming machine. Background technique [0002] For kitchen knives and other similar knives that are used in daily life, the shape and thickness of the back of the knife are very important for use. Consumers generally like thicker backs of knives, which can increase texture and save effort. But thickening the back of the blade is a difficult problem in the prior art: the existing punching and pressing knives cannot solve the above technical problems, and the back of the knife is as thick as the body of the knife; although the back of the knife can be thickened by hand forging, because there is no knife The shape of memes is irregular, and the efficiency is low. Generally, it takes 2 minutes to complete the rough blank processing of the blade back of a knife; during the processing, coal needs to be burned, which consumes a lot of energy and causes serious pollution.
