Shearing device for fixing and shearing pipes synchronously

Abstract

The invention relates to the technical field of shearing, and discloses a shearing device for fixing and shearing pipes synchronously. The shearing device comprises a middle plate, wherein the surfaceof the middle plate is provided with a curved groove; the upper portion of the middle plate is movably connected with blades; the surfaces of the blades are fixedly connected with sliding columns; the upper faces of the blades are fixedly connected with an upper plate; the surface of the upper plate is provided with a limiting groove; the lower portion of the middle plate is movably connected with a sliding block; the surface of the sliding block is fixedly connected with a sliding shaft; and one end, close to the sliding shaft, of the sliding block is fixedly connected with a clamping claw.The four blades are evenly distributed with the center of the upper plate as the reference, and the blades rotate for cutting, so that the situation that the stress is even everywhere when the pipes are cut again is ensured, and the pipes are not prone to deforming so as to avoid uneven wrinkles at the incision caused by deformation; and the pipes to be cut are machined to the standard that can beused directly at one time without polishing and adjusting again, so that the time is saved, the work load is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shearing, in particular to a shearing device for pipes which can be fixed and sheared simultaneously. Background technique [0002] Generally, the size of the pipes shipped directly from the factory is relatively long, so we need to cut the pipes again according to the specific usage conditions, and the traditional shearing cutting device that moves the blade up and down to cut the pipes has the following shortcomings: [0003] 1. The impact force of the blade when it moves up and down quickly is very large. At the moment when the blade touches the surface of the pipe to be cut without starting to cut the pipe, the impact force of the blade will cause the pipe itself to deform, resulting in the pipe after cutting. The cutting edge of the pipe is uneven and slightly deformed. In the subsequent use, the pipe needs to be adjusted and polished again, which is troublesome, time-consuming and increases the work...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a shearing device for pipes that can be fixed and sheared simultaneously, which has the advantages of simultaneous fixing and shearing, avoiding deformation of the sheared pipes and uneven cuts, It solves the problem that the traditional shearing cutting device that moves up and down will cause the sheared pipe to deform, and the fixing device and the shearing device are divided into two independent parts, which cannot be fixed and sheared simultaneously.
