Problems solved by technology

[0008] Aiming at the existing problems of using a milling machine to process easily damaged milling cutters when cutting steel with a large thickness, the milling cutter needs to be replaced regularly, the processing cost is high, and it is difficult to adapt to different blade angles. The fixture can adjust the angle of the cutting edge surface to be processed by the blade, so that the cutting surface of the cutting edge of the blade is in a vertical state, and efficient and high-quality cutting can be performed without using a milling machine

Abstract

The invention discloses a cutting clamp and machining process of a long blade for a plastic pulverizer, and belongs to the technical field of mechanical tools. The cutting clamp comprises bases, a rotary shaft, a base plate, a pressing plate and a dial. The bases are fixed to a workbench of a machine tool, and the base plate is fixed to the middle of the rotary shaft. The two ends of the rotary shaft are rotationally connected to the bases, and the dial is arranged at one end of the rotary shaft. An indicatrix on the bases points to the dial, and the rotating angle of the rotary shaft is observed. The base plate is fixedly connected with the pressing plate, the space formed between the pressing plate and the base plate serves as a clamping position of a long blade blank, and the long bladeblank is fixed to the base plate through the pressing plate. The cutting clamp is used in combination with a cutting process of flame cutting, and the machining process of the long blade for the pulverizer is optimized. The cutting clamp is simple in structure and reasonable in design, the cost is reduced by the machining process, the machining performance of a cut face is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical cutting tools, and more specifically relates to a cutting fixture and a processing technology of long blades for plastic shredders. Background technique [0002] Plastic shredder refers to crushing various plastic plastics and rubber, such as plastic profiles, pipes, rods, silk threads, films, and waste rubber products. The crushed pellets can be directly extruded as raw materials for production. The blade used to crush materials on a plastic grinder is called a plastic grinder blade, also called a plastic mechanical blade. Because the plastic is hard and the rubber is elastic, the sharpness of the plastic grinder blade determines the fineness of the material crushed. The sharpness of the blade depends on the shape angle of the cutting edge, the hardness of the blade and its internal metallographic structure. Therefore, crushing different types of plastics or rubber requires blades with diffe...
