Technology for manufacturing flattened bent pipe

Abstract

The invention discloses a technology for manufacturing a flattened bent pipe and particularly relates to the technical field of pipe machining. The technology for manufacturing the flattened bent pipecomprises the specific following machining steps that firstly, the drawing is analyzed; secondly, materials are determined; thirdly, the materials are purchased; fourthly, the materials are rechecked; fifthly, the materials are identified and transplanted; sixthly; blanking of the pipe is conducted; seventhly, deburring and heat treatment is conducted; eighthly, the pipe is filled with steel grit; ninthly; the pipe is flattened; tenthly, cold bending is conducted; eleventhly, shaping in a mold is conducted; twelfthly, examination is conducted; thirteenthly, pipe ends are cut; fourteenthly, groove cutting is conducted; fifteenthly; shot blasting and derusting are conducted; sixteenthly, painting is conducted; and seventeenthly, packaging is conducted. According to the technology for manufacturing the flattened bent pipe, the steel grit is utilized, and the pipe is filled with steel grit; the three steps of flattening, cold bending and shaping in the mold are conducted so that deformation when the inner wall and the outer wall of the whole pipe are flattened and bent is consistent; and the finished product rate of the pipe is improved greatly, and in addition, smoothness of the surface of the pipe is higher. By utilizing the machining method, machining of pipes of various calibers, wall thickness, bending angles and radii can be achieved; machining is rapid; efficiency is high;technological requirements for working staff are not high; and the pipe machining quality is high.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, and more specifically, the invention relates to a manufacturing process of a flattened bent pipe. Background technique [0002] At present, the forming method of the bent pipe body product was originally a manual bending method. When bending the pipe fittings, each step is manually completed, such as manual feeding, and flattening the pipe fittings. The pipe fittings (flat pipe) are fixed on the bending machine, and then the flat pipe is pressed against the pressure plate, and the flat pipe is manually turned on to bend the flat pipe; the forming quality of the whole processing process is unstable, and the manual bending does not conform to the product drawing, and correction work is required; [0003] The traditional pipe bending process requires manual operation, and skilled workers are required to manually fix and use the pressing plate, which increases the dependence on skille...

Problems solved by technology

[0002] At present, the forming method of the bent pipe body product was originally a manual bending method. When bending the pipe fittings, each step is manually completed, such as manual feeding, and flattening the pipe fittings. The pipe fittings (flat pipe) are fixed on the bending machine, and then the flat pipe is pressed against the pressure plate, and the flat pipe is manually turned on to bend the flat pipe; the forming quality of the whole processing process is unstable, and the manual bending does not conform to the product drawing, and correction work is required;

[0003] The traditional pipe bending process requires manual operation, and skilled workers are required to manually fix and use the pressing plate, which increases the dependence on skilled workers, which is not conducive to development, and not only the production efficiency is low, but also the quality cannot be guaranteed, especially for processing The smoothness of the outer wall and inner wall of the bent pipe has great shortcomings in the prior art. The smoothness is low, which not only affects the appearance of the product, but also may cause inconvenience in the later use and installation of the product.
