Problems solved by technology

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 the meme is irregular and the efficiency is low. Generally, it takes 2 minutes to complete the rough processing of the blade back of a knife; coal burning is required during the processing, which consumes a lot of energy and causes serious pollution

Embodiment Construction

[0008] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0009] Such as figure 1 As shown, the knife back forming machine of the present invention includes an upper mold 5, a lower mold 9, a fixed side mold 2, a movable side mold 6, a main hydraulic device and an auxiliary hydraulic device fixed on the support. Upper die 5 is fixed on the plunger 4 ends of main hydraulic device, and its lower shape adapts to the required shape on the back of a knife. Lower mold 9 is fixed on the support, and its top is provided with the knife-edge groove that is used for fixing knife. The fixed side form 2 is fixed on the machine base. The movable side mold 6 is fixed on the end of the plunger 8 of the auxiliary hydraulic device. The shape of the combination of fixed side form 2 and movable side form 6 is adapted to the required shape of the cross section of knife.

[0010] In order to further fix the knife in the mold du...

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. Conten...
