Abstract

The present invention is to provide a kind of thread screw on and-off machine clamp.On the stubborn clasp of thread screw on and-off machine, surrounding is provided with clamp, and clamp is provided with frictional layer.Use clamp of the present invention, it is possible to guarantee pipeline will not be damaged, extend the service life of pipeline, and large-scale pipeline can be carried out twisting button connection or dismounting by this thread screw on and-off machine clamp, have and adapt to the wide and advantage of protection body.Suitably the clamp as thread screw on and-off machine uses.

Description

A kind of thread screw on and-off machine clamp
Technical field
The present invention is to provide a kind of thread screw on and-off machine clamp of mechanical field application.
Background technology
During the effective screwed connection of existing band large-scale metal, dismounting needs thread screw on and-off machine, equipped with clamp on thread screw on and-off machine.Made at present Clamp be typically tooth profile metal structure, stubborn button time on pipe, easily leave impression, this impression can destroy pipeline configuration, And affect attractive in appearance, eventually cause pipe end serious damage, even can not be continuing with.
Summary of the invention
Twist button pipeline breakage to reduce, the invention provides a kind of thread screw on and-off machine clamp.This clamp is by setting on clamp There is frictional layer, solve thread screw on and-off machine clamp and do not destroy the technical problem of pipeline.
The present invention solves the scheme that technical problem used:
On the stubborn clasp of thread screw on and-off machine, surrounding is provided with clamp, and clamp is provided with frictional layer.Described frictional layer be sisal fiber and Phenolic resin pressing thing, pressing thing is adhered directly on clamp.
Good effect, uses clamp of the present invention, it is possible to ensures that pipeline will not be damaged, extends the service life of pipeline, and This thread screw on and-off machine clamp can carry out twisting button and connect or dismounting large-scale pipeline, has and adapts to the wide and advantage of protection body.Suitable The preferably clamp as thread screw on and-off machine uses.
Accompanying drawing explanation
Fig. 1 is that the present invention twists snap ring structure figure;
Fig. 2 is clamp structure figure of the present invention.
In figure, 1. twist clasp, 2. clamp, 2.1. frictional layer.
Detailed description of the invention
According to the figure, on the stubborn clasp 1 of thread screw on and-off machine, surrounding is provided with clamp 2, and clamp is provided with frictional layer 2.1.
Described frictional layer is sisal fiber and phenolic resin pressing thing, and pressing thing is adhered directly on clamp.
Sisal fiber intensity is high, rub resistance, after being combined with phenolic resin, forms composite, and this composite entirety has There is a higher mechanical strength, and rub resistance, as the frictional layer of clamp, pressure force is high, not damages metal pipe-wall.
The use process of the present invention:
To wait that the pipeline one end twisting button, through twisting in clasp, starts hydraulic mechanism and makes thread screw on and-off machine clamp tighten up on pipeline outer wall, And clamp, the other end is twisted clasp and is rotated, and is screwed by the screw thread between pipeline and pipeline or unclamps, it is achieved the stubborn button of pipeline.
Owing to clamp is provided with frictional layer, will not leave behind impression so contacting with tube wall, it is ensured that pipeline stands intact.

Claims (1)

1. a thread screw on and-off machine clamp, is characterized in that: the upper surrounding of stubborn clasp (1) at thread screw on and-off machine is provided with clamp (2), and clamp sets There is frictional layer (2.1);
Described frictional layer is sisal fiber and phenolic resin pressing thing, and pressing thing is adhered directly on clamp.
