Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and particularly to a pipe cutting machine convenient for clamping pipe fittings. Background Technique

[0002] A water jet cutting machine is a cutting equipment that uses ultra-high pressure water jets for cold cutting. Since the water jet is cold cutting, it does not generate heat effect, does not deform, has no slag hanging, no ablation, and does not change the physical and chemical properties of the material; the document with the existing application publication 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 arranged at the bottom of the top plate, a second moving mechanism is arranged at the bottom of the first moving mechanism, a second moving block is arranged on the second moving mechanism, a cutting tool is fixedly installed at the bottom of the second moving block, a water pumping mechanism is arranged at the top of the top plate, a drying mechanism is arranged on the top of the fixed table, support columns are fixedly installed at the bottom of the fixed table, a water collecting tank is opened at the bottom of the fixed table, and a filter box is arranged inside the water collecting tank; through the combined use of the first support rod and the second support rod in its solution, a support member for the workpiece can be formed. When the water jet damages the support member, there is no need to replace the entire support member. By replacing the severely damaged first support rod and second support rod, the economic damage caused by the replacement of the support member can be reduced, and the practical performance of the device can be improved.

[0003] In the above solution and the prior art during the cutting process, in order to ensure the stability of the workpiece, the clamping and fixing method is generally rather troublesome; especially for equipment used for pipe fitting cutting, in a small amount or temporary cutting work, generally the water jet device is arranged on the corresponding frame body, and the pipe fittings are clamped and fixed through the corresponding clamping components, and its stability is difficult to meet the requirements. Moreover, for pipe fittings with a slightly larger diameter, its stability needs to be further improved; during the processing operation, some pipe fittings are cut once, and after cutting, another pipe fitting is replaced for cutting; some need to cut multiple segments of the same pipe fitting.
