Embodiment 1

[0029] A pipe bending process for complex-shaped pipes, comprising the following steps:

[0030] 1) see figure 1 with figure 2 As shown in the pipeline structure diagram, the pipeline parameters need to be determined according to the engineering drawing, and the pipeline is selected according to the pipeline parameters, refer to image 3 for the selected pipeline;

[0031] 2) see Figure 4 As shown, make the corresponding elbow positioning fixture according to the pipeline determined in step 1), Figure 4 positioning fixture for the bend;

[0032] 3) see Figure 5 As shown, the pipeline selected in step 1) is installed and fixed on the elbow positioning fixture made in step 2);

[0033] 4) Select the bending device, install it on the elbow positioning fixture prepared in step 2), and fix the stretched end of the bending device to the part of the pipeline that needs to be bent;

[0034] 5) see Image 6 As shown, select the oxygen acetylene combustion device, turn on th...

Abstract

The invention discloses a complex-shaped pipe bending technology. The technology comprises the following steps of observing an engineering drawing, determining pipe parameters, selecting pipes according to the pipe parameters, building a pipe bending positioning clamp according to the engineering drawing, positioning the pipes on the pipe bending positioning clamp, and bending the pipes in the horizontal direction and the vertical direction. The technology has the good flexibility and can bend pipes freely according to the engineering requirement, so that the shapes of the pipes meet the requirement for a building, and meanwhile the technology has the low requirement for tools and lowers the input cost.

Description

technical field [0001] The invention relates to a pipe bending process for complex-shaped pipes. Background technique [0002] Most of the existing pipe benders use mechanical pipe benders, but mechanical pipe benders have the following defects: [0003] 1) It is impossible to realize the multi-direction and large arc length bending of the pipeline; [0004] 2) Restricted by machinery and molds, the flexibility is poor and not arbitrary; [0005] 3) It is necessary to use a special pipe bending machine and a special mold, which leads to a large initial investment cost. Contents of the invention [0006] The technical problem to be solved by the present invention is to provide a pipe bending process with complex shapes. This process has better flexibility and can bend pipes arbitrarily according to engineering needs, so that the shape of the pipe can meet the needs of construction. At the same time, the process requires Lower, reducing input costs. [0007] In order to ...
