Novel double-reduction steel bar shearing machine

Abstract

The invention discloses a novel double-reduction steel bar shearing machine. The novel double-reduction steel bar shearing machine comprises a machine frame, wherein a shell which is formed by combining steel plates through welding, and a power device are arranged on the machine frame, a driving shaft, a driven shaft and a crankshaft are connected to the rear oration of the shell in a rotary mode, the driving shaft is in transmission connection with the power device, the driving shaft is also in transmission connection with the driven shaft, a driven gear and a clutch gear which can be in meshed transmission are arranged at the ends of the same sides of the driven shaft and the crankshaft and located outside the shell, an installation groove is formed in the upper portion of the front side of the shell, a fixed cutter is arranged on the front portion of the installation groove, the crankshaft is connected with a movable cutter through a connecting rod, the movable cutter is matched with the fixed cutter, a slide rail allowing the connecting rod to move back and forth is arranged in the shell, and the center line, in the forward and backward direction, of the slide rail and the center line, in the forward and backward direction, of the shell coincide. The novel double-reduction steel bar shearing machine has the advantages that the machining method is simple, the production efficiency is high, product cost is low, the strength and the shock resistance of the shell are greatly improved, the head of the shearing machine is prevented from being broken, the shearing machine is prevented from being torn, the service life is prolonged, and the product maintenance rate is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing, and in particular relates to a novel two-stage deceleration 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] A steel bar cutter is a tool used to cut steel bars. Generally, there are fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. It is one of the necessary equipment for steel bar processing, and it is mainly used for cutting steel bars to fixed length in housing construction, bridges, tunnels, power st...

AI Technical Summary

Problems solved by technology

[0004] Because the steel bar cutting machine has to bear a large impact force at the moment of cutting, the shell is required to have a considerable thickness and weight, so the existing cutting machine shells are all cast iron parts formed in one piece. In recent years, although there are welded shells Body appears, but because there is no structural change, such as three-stage deceleration has been implemented, the slideway opening is designed on the side of the shell, and the slideway is designed on the side of the center line of the cutting machine, resulting in swinging and shaking of the cutting machine during operation , resulting in broken ends and tears of the shell. Therefore, the traditional cutting machine structure not only has high production costs and is inconvenient to maintain, but also has not solved the problem of broken ends and tears of the shell that plagued the development of the cutting machine industry.
