Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to a compression-type T-shaped tee pipe processing device. Background Technology
[0002] This technology primarily utilizes metal pipes for gas transmission, which are equipped with tees or multi-way connectors at branch points. This technology mainly targets T-type tees, such as... Figure 1 As shown. Currently, traditional T-type tees use separate first straight pipe 10 and second straight pipe 20 for welding connection. Before welding, it is necessary to make a round hole in the first straight pipe 10 in the longitudinal direction and a round hole in the second straight pipe 20 in the horizontal direction, as shown. Figure 2 As shown. The existing processing method has the following problems: First, the processing efficiency of cutting holes in the first straight pipe 10 and the second straight pipe 20 is low and complex; second, when welding the first straight pipe 10 and the second straight pipe 20, welding can only be done on their outer edges, making internal welding difficult; third, when welding the first straight pipe 10 and the second straight pipe 20 together, a specialized positioning fixture is required to ensure that the longitudinal circular hole on the first straight pipe 10 coincides with the second straight pipe 20. Therefore, it is evident that the existing technology has low processing efficiency and poor processing quality.
[0003] Therefore, there is an urgent need to propose a simple, easy-to-process, and reliable extrusion-type T-shaped tee processing device. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a compression-type T-shaped tee pipe processing device. The technical solution adopted by this utility model is as follows:
[0005] A compression-type T-tee pipe processing device processes a straight pipe section to obtain a T-tee pipe containing branch pipe sections. An elliptical hole is formed in the straight pipe section; the elliptical hole is arranged along the axial direction of the straight pipe section, and the circumference of the elliptical hole is equal to the circumference of the branch pipe section. The compression-type T-tee pipe processing device includes: a second worktable, a rear support frame and a rotating shaft support rod fixed to the second worktable, a support block rotatably sleeved on the rotating shaft support rod and placed on the second worktable, and a center block with one end fixed to the rear support frame and the other end supported by the support block. The system comprises a rod, a circular column mounted on a central rod, a second elliptical column mounted on the circular column, a second lower mold and a second upper mold fitted onto the central rod, and linkage plates on both sides of the second lower mold and the second upper mold. A third circular groove is formed inside the second lower mold. A fourth circular groove is formed inside the second upper mold. A blind hole is formed within the fourth circular groove. The blind hole has the same outer diameter as the pipe section. The second elliptical column is fitted into the elliptical hole. The circular column has the same inner diameter as the pipe section. A compression cylinder is mounted on the upper part of the second upper mold.
[0006] Furthermore, a first connecting pin is provided on the side of the second lower mold; a second connecting pin is provided on the side of the second upper mold; a strip groove is provided in the linkage plate; the first connecting pin and the second connecting pin are provided in the strip groove.

There is no weld between the branch pipe section and the straight pipe section, and it is formed by extruding a part of the original straight pipe section, resulting in better sealing and high processing efficiency.
[0010] (2) This utility model supports the central rod by setting a rear support frame and a support block, and sets a circular column and a second elliptical column on the central rod. The second elliptical column is connected to the elliptical hole and the circular column is used to extrude to form the pipe section, which has high processing efficiency.
[0011] (3) This utility model sets a second lower mold and a second upper mold, and sets a blind hole in the second upper mold. The circular cylinder extrudes the four sides of the elliptical hole and forms a pipe section between the circular cylinder and the blind hole, which has reliable fixed support.

[0030] like Figure 1 , Figures 3 to 8As shown, this embodiment provides an extrusion-type T-tee pipe processing device to process a straight pipe section 1 to obtain a T-tee pipe containing branch pipe sections 2. Specifically, an elliptical hole 11 is laser-drilled into the straight pipe section 1; the elliptical hole 11 is arranged along the axial direction of the straight pipe section 1, and the perimeter of the elliptical hole 11 is equal to the perimeter of the branch pipe section 2. The elliptical hole 11 is then molded from the inside out to obtain the T-tee pipe containing the branch pipe sections 2.
[0031] Specifically, this embodiment uses a compression molding process to obtain a T-shaped tee pipe. The processing device includes: a second worktable 201, a rear support frame 202 and a rotating shaft support rod 205 fixed on the second worktable 201, a support block 206 rotatably mounted on the rotating shaft support rod 205 and placed on the second worktable 201, a central rod 207 with one end fixed to the rear support frame 202 and the other end supported by the support block 206, a circular column 210 mounted on the central rod 207, a second elliptical column 211 mounted on the circular column 210, a second lower mold 203 and a second upper mold 204 mounted on the central rod 207, and linkage plates 208 on both sides of the second lower mold 203 and the second upper mold 204.
