specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 6 Describe this embodiment, a support device for anti-deformation welding of thin-walled pipe fittings in this embodiment, which includes a support 1, a handle 2 and a lifting rod 3, and the support 1 includes a circular platform section 1-1 and a cylindrical section 1-2, the large end of the round table section 1-1 is fixedly connected to one end of the cylindrical section 1-2, the handle 2 is a cuboid member, one end of the handle 2 is fixedly connected to the other end of the cylindrical section 1-2, and the handle 2 The other end of the handle is processed with a circular through hole 2-1, and the handle 3 is worn in the circular through hole 2-1 on the handle 2.

[0016] The first pipe 10 is fixed, the support 1 of the support device of the present invention is put into the first pipe 10, the circular platform section 1-1 of the support 1 is in contact with the inner conical surface of one end of the fir...

specific Embodiment approach 2

[0018] Specific implementation mode two: combination Figure 1 to Figure 6 To illustrate this embodiment, the diameter of the large end of the circular frustum segment 1-1 is the same as that of the cylindrical segment 1-2. Such design ensures that the position of the first pipe fitting and the second pipe fitting is accurate when they are butt welded. Other compositions and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0019] Specific implementation mode three: combination Figure 1 to Figure 6 To illustrate this embodiment, the central axis of the circular through hole 2-1 is perpendicular to the central axis of the cylindrical section 1-2. With this design, the operator can exert less force during the process of withdrawing the supporting device after welding. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an anti-deformation supporting device for assembling and welding of thin-wall pipes and relates to an anti-deformation supporting device. According to the anti-deformation supporting device for assembling and welding of the thin-wall pipes, the problem that existing thin-wall pipes are prone to deformation when butting joint assembling and welding are conducted is solved. The anti-deformation supporting device for assembling and welding of the thin-wall pipes comprises a supporting piece, a lifting handle and a lifting rod. The supporting piece comprises a circular truncated cone section and a cylindrical section, and the big end of the circular truncated cone section is fixedly connected with one end of the cylindrical section. The lifting handle is a cuboid component, one end of the lifting handle is fixedly connected with the other end of the cylindrical section, and a circular through hole is machined in the other end of the lifting handle. The lifting rod is installed in the circular through hole in the lifting handle in a penetrating mode. The anti-deformation supporting device for assembling and welding of the thin-wall pipes is used for providing support during butting joint assembling and welding of the thin-wall pipes.

Description

technical field [0001] The invention relates to a supporting device for preventing deformation, in particular to a supporting device for preventing deformation when welding thin-walled pipe fittings. Background technique [0002] The gas turbine is an advanced technology imported from the American GE company. It uses natural gas to burn to do work, and converts the heat energy of combustion into electrical energy. At the same time, two thin-walled pipe fittings are butt welded, and the wall thickness of the pipe fittings is only a few millimeters. After welding, it will be seriously deformed, which does not meet the technical requirements, affects the welding quality, and brings hidden dangers to the normal operation of the unit. Contents of the invention [0003] The object of the present invention is to solve the problem that existing thin-walled pipe fittings are easily deformed during butt welding, and further provide a supporting device for preventing deformation of t...
