Composite clamping device for rows of pipes

Abstract

The invention relates to a composite clamping device for rows of pipes. The composite clamping device comprises a fixed clamping device and a floating clamping device which have the same structure, wherein the floating clamping device and the fixed clamping device are connected through a tool retracting device; the fixed clamping device comprises horizontal clamping oil cylinders fixed on the two sides of a box; the two horizontal clamping oil cylinders are connected with synchronous racks through connecting rods; the connecting rods are meshed with a synchronous gear on the upper and lower sides; a vertical clamping device slidably connected with vertical guide posts is arranged over the box; the vertical guide posts are fixed on the box; a vertical clamping oil cylinder is fixed under the box; the vertical clamping oil cylinder and the vertical clamping device are connected to a vertical connecting frame; and saw blade retainers and the tool retracting device are arranged on the vertical clamping device. Rows of steel pipes can be horizontally and vertically clamped, the stability of the lower half part of a saw blade is kept by the saw blade retainers, and the composite clamping device has the advantages of simple and compact structure, good clamping effect, capability of retracting a tool and realizing automatic control, and the like.

Description

technical field [0001] The invention relates to a clamping device used in steel pipe gang sawing machines and other occasions where compound clamping is required for sawing, in particular to a compound clamping device for pipe arrangement. Background technique [0002] The horizontal clamping of the traditional clamping device adopts hydraulic synchronization, which is easy to cause the center of the clamped pipe and the center of the saw blade to deviate. Two oil cylinders are used for vertical clamping, and hydraulic synchronization is also adopted, which may easily cause vertical clamping jamming. At the same time, it does not have the function of clamping and letting the knife. When the saw blade is lifted, it is easy to scratch the section, and there is no saw blade holder, so the quality of the saw section is unstable. Vertical clamping and horizontal clamping are not installed in a box, the structure is huge and difficult to install, and the clamped material head is ...

[0002] The horizontal clamping of the traditional clamping device adopts hydraulic synchronization, which is easy to cause the center of the clamped pipe and the center of the saw blade to deviate

Two oil cylinders are used for vertical clamping, and hydraulic synchronization is also adopted, which may easily cause vertical clamping jamming

At the same time, it does not have the function of clamping and letting the knife out. When the saw blade is lifted, it is easy to scratch the section, and there is no saw blade holder, so the quality of the saw section is unstable.

Vertical clamping and horizontal clamping are not installed in a box, the structure is huge and difficult to install, and the clamped material head is long and the yield is low.
