Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, in particular to a pipe cutting machine which is convenient for clamping pipe fittings. Background Art

[0002] A water jet cutting machine is a cutting device that uses ultra-high pressure water jets for cold cutting. Since the water jet is cold cutting, it does not produce thermal effects, deformation, slag, or ablation during cutting, and does not change the physical and chemical properties of the material. The existing document with announcement number CN112809835A discloses a water jet cutting machine, which includes a fixed table, a support rod is fixedly installed on the top of the fixed table, a top plate is fixedly installed on the top of the support rod, a first moving mechanism is provided at the bottom of the top plate, a second moving mechanism is provided at the bottom of the first moving mechanism, a second moving block is provided on the second moving mechanism, and a second moving block is provided on the second moving mechanism. A cutter is fixedly installed at the bottom of the two moving blocks, a pumping mechanism is provided on the top of the top plate, a drying mechanism is provided on the top of the fixed platform, a supporting column is fixedly installed at the bottom of the fixed platform, a water collecting tank is provided at the bottom of the fixed platform, and a filter box is provided inside the water collecting tank; the scheme can form a support part for the workpiece through the coordinated use of the first support rod and the second support rod. When the water jet damages the support part, there is no need to replace the entire support part. By replacing the severely damaged first support rod and the second support rod, the economic damage caused by the replacement of the support part can be reduced and the practical performance of the device can be improved.

[0003] In the above-mentioned schemes and the prior art, in order to ensure the stability of the workpiece during the cutting process, the clamping and fixing method is generally more troublesome; especially for equipment used for pipe cutting, when performing a small amount or temporary cutting work, the water jet device is generally set on the corresponding frame, and the pipe is clamped and fixed by the corresponding clamping assembly. Its stability is difficult to meet the requirements. Moreover, for pipes with slightly larger diameters, its stability needs to be improved. In the processing operation, some pipes are cut once, and another pipe is replaced for cutting after the cutting is completed; some require multiple sections of cutting on the same pipe. This process not only requires repeated clamping operations on the pipe, but also has corresponding requirements for its clamping convenience and stability. The existing pipe cutting device lacks a suitable clamping auxiliary device to meet its processing requirements, and needs to be improved and optimized.
