Novel processing technique of reinforcing steel bar cutting machine shell

Abstract

The invention discloses a novel processing technique of a reinforcing steel bar cutting machine shell. The novel processing technique comprises the following steps: (1) dividing the shell into two vertical panels, a front closing plate, a back closing plate, a bottom closing plate, a holding force position doubling plate and a fixed knife component; (2) measuring the sizes of the parts and components, and drawing a part graph with designed size; (3) cutting the vertical panels and the holding force position doubling plate by using a numerical control cutting machine, shearing the front closing plate, the back closing plate and the bottom closing plate, carrying out stamp forming on the plates, and forming the fixed knife component through a casting steel member in one piece; (4) welding the holding force position doubling plate at the corresponding positions of the side faces of the two vertical plates; and (5) welding the parts and the components to form an integral shell. The novel processing technique disclosed by the invention is simple in processing mode, high in production efficiency and low in cost; and by using the novel processing technique, the shell strength is greatly improved, the service life is prolonged, and the product maintenance rate is fully reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing, and in particular relates to a novel processing technology for a shell of a steel bar cutting machine. Background technique [0002] The construction industry is a pillar industry for social and economic development. The main raw materials used in the construction industry are steel bars and cement, and steel bars are the backbone of all buildings. Steel bar cutting machines are the most widely used machinery in engineering and construction machinery. Appears to greatly save manpower and material resources, and improve labor efficiency. [0003] Because the steel bar cutting machine requires considerable thickness and weight, the existing cutting machine shells are all integrally formed cast iron parts. Although the cast iron parts can meet the thickness and weight requirements, due to the poor material density, they often cannot be used for a long time. Withstand...

AI Technical Summary

Problems solved by technology

[0003] Because the steel bar cutting machine requires considerable thickness and weight, the existing cutting machine shells are all integrally formed cast iron parts. Although the cast iron parts can meet the thickness and weight requirements, due to the poor material density, they often cannot be used for a long time. Withstand the strong impact force when the steel bar is cut, and the quality of this kind of machine users is generally low, and the passivated cutter head cannot be found and replaced in time. Therefore, the damage rate of the cutting machine is too high, and it is everywhere in the foundry. Visible destroyed cutter housing

In addition, due to the complex structure of the cutting machine shell, the casting process and modeling are difficult and the process is cumbersome, which makes the production efficiency too low and cannot be mass-produced in large quantities.
