Self-lubricating snapping shear for high-speed wire rod finish rolling production line

Abstract

The invention relates to a device used on a high-speed wire rod finish rolling production line, in particular to a self-lubricating snapping shear for the high-speed wire rod finish rolling production line. The self-lubricating snapping shear comprises a base bottom plate, a base side plate, an after-shearing channel and a driving device, and a rolled material slides out from the after-shearing channel of a rolled material channel after being sheared; the snapping shear is a single shear blade, a shear arm bearing seat is arranged on the base side plate, and a shear arm of the single shear blade is mounted on the shear arm bearing seat through a rotating shaft, so that the shear arm of the single shear blade rotates by taking the rotating shaft as a fulcrum; a pushing connector is arranged at the end of a piston of the driving device, and the pushing connector is connected with the upper end of the shear arm of the single shear blade; the lower end of the shear arm of the single shear blade is provided with a shear blade for shearing the rolled material. The self-lubricating snapping shear is simple in structure, abrasion of rotating parts and consumption of spare parts are reduced, precise shearing is achieved, shearing stability rate is improved, safety risks and equipment losses are reduced, the purpose of green, energy-saving and decrement production is achieved, and the trend of enterprise development and social progress is conformed to.

Description

technical field [0001] The invention relates to a device used in a high-speed wire rod finish rolling production line, in particular to a snap-off shear. Background technique [0002] Because of its simple structure and no need for power supply, the snap-off shear is widely used. It is mainly used as an important auxiliary equipment in the production of high rods, high-speed wires, tool steel, and stainless steel. Therefore, the snap-off shear is indispensable in front of the high-speed wire rod finishing mill. The key equipment, when the finishing rolling unit breaks down, can effectively cut off the incoming materials before finishing rolling through the interlocking device, reduce the impact of continuous incoming materials on the finishing rolling unit, reduce equipment failure losses and safety accidents caused by flying steel.

Problems solved by technology

[0003]In the prior art, the snap-off shears are in the form of double cutting blades, the transmission is a link mechanism, and the rotating shafts are all made of copper sleeves. The structure is complicated, and it is not easy to maintain and repair online , long-term use, the copper sleeve is worn out, and the gap between the two cutting blades increases. Because the shearing arm and the connecting rod are relatively long, the movement error of the long rod connecting rod is enlarged, and the movement of the lower shearing arm lags behind the upper shearing arm obviously, resulting in , The lower cutting edge has a wrong edge, which cannot play the role of cutting off the incoming material, forming a safety hazard and causing an accident
