Integral binding type bundling machine

Abstract

The invention discloses an integrated binding-typed strapping machine, comprising a strapping worktable, a wirerope binding mechanism which is arranged above the binding worktable and used for eliminating the clearance of laminates, a wirerope traction mechanism which leads a workpiece to roll to-and-fro on the worktable surface and two electric lifting trolleys which are arranged at two sides ofthe worktable, and lead the workpiece to be vertically lifted upwards and downwards and to move axially along the workpiece. During the production process, by the operations of lifting-up, walking and falling-off, the electric lifting trolley removes the previous cylinder out of the binding worktable after the binding of the workpiece is completed and moves the next cylinder to be bound into the binding worktable so that the binding operation can be carried out; therefore, the integrated binding-typed strapping machine realizes the integrated binding to the long internal cylinder, and can carry out integrated binding of the internal cylinder which is welded with a sealing head and the welding stress of which is eliminated by backfire, and overcomes the defects that: during the segmentation binding, the quality of deep ring welding seam is difficult to be ensured, and the integrated backfire can not be carried out on the internal cylinder where the sealing head is welded so as to eliminate the welding stress.

Description

Technical field [0001] The invention relates to a device for producing a high-pressure container, in particular to a wrapping device for producing a multi-layer wrapping high-pressure container. Background technique [0002] At present, in the production of long multi-layered high-pressure containers, limited by the bandaging machine, it can only be bandaged in sections, that is, the entire cylinder body is first decomposed into multiple tube sections for section wrapping, and then each tube section is combined and welded Finally, the head is welded. Using this production process, the welding part must be beveled before the combined welding of each tube section. The process is complicated. Because of the deep girth welding during welding, the weld is easy to appear. Defects such as slag inclusions and pores need to be tested for flaws in the weld. In addition, the entire inner cylinder and the head cannot be tempered as a whole due to the use of segmented wrappers to eliminate we...

AI Technical Summary

Problems solved by technology

[0002] At present, due to the limitation of the wrapping machine in the production of long multi-layer wrapped high-pressure vessels, only segmental wrapping can be carried out, that is, the entire cylinder body is first decomposed into multiple barrel sections for segmental wrapping, and then combined welding of each barrel section , and finally weld the head. With this production process, the welding part must be grooved before the combined welding of each cylinder section. The process is complicated. Because there is deep circular seam welding during welding, the weld is prone to For defects such as slag inclusions and pores, it is necessary to perform flaw detection on the weld seam. In addition, due to the use of segmental wrapping, the entire inner cylinder and head cannot be tempered as a whole to eliminate welding stress and refine grains. There are potential safety hazards in bandaging high-pressure vessels
