Description

Technical Field

[0001] The invention relates to the technical field of pipe equipment, and in particular to a pipe clamping device. Background Art

[0002] During the pipe production process, the pipe will be cut into different lengths according to needs. During the cutting process, a pipe clamping device is required to fix the pipe to prevent the pipe from shaking during the cutting process and affecting the welding quality.

[0003] In the prior art, the clamping device is generally composed of a cylinder and two semicircular clamps. The curvature of the semicircular clamps is designed according to the outer diameter of the pipe. For example, Chinese patent CN201710997812.1 discloses a pipe clamping device in a PVC pipe production line. The clamp exerts mutual force on the outer wall of the PVC pipe, and the protective film is compressed between the clamp and the PVC pipe wall, which not only strengthens the friction between the clamp and the PVC pipe, but also prevents the PVC pipe from being damaged by the pressure exerted by the solid inner wall of the clamp, thereby achieving the effect of protecting the PVC pipe.

[0004] However, for pipes of different specifications, it is necessary to frequently replace the clamps when using clamping devices to fix the pipes, which is extremely inconvenient. On the other hand, in order to improve production efficiency, it is often necessary to cut multiple pipes at the same time, using multiple clamping devices. Before cutting, each clamping device needs to be adjusted separately to fix the pipes through the clamping devices, which consumes manpower and takes a long time, affecting production efficiency.
