[0002] During the pipe processing, pipes are usually bent to facilitate the installation and use of parts. Currently, pipe bending is generally carried out using mechanical bending equipment, including automatic pipe bending machines and manual pipe bending machines.

[0003] Based on the existing problems with manual pipe bending machines in actual use, the bending angle of the pipes cannot be accurately positioned due to the manual bending operation, resulting in deviations in the bending angle. Therefore, we propose a pipe bending machine for processing stainless steel grooved pipes to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending machine for processing stainless steel grooved pipe fittings, comprising a bending machine body, the bending machine body including a frame body, a disc seat fixedly installed on the outer side of the frame body, a central shaft fixedly installed on the disc seat, a base fixedly installed at the bottom end of the central shaft body, a connecting bracket rotatably connected to the base, an internal annular groove opened on the disc seat, a vertical shaft inserted inside the internal annular groove, a limit plate fixedly installed at the top and bottom ends of the vertical shaft, a limit plate at the bottom end of the vertical shaft being fixedly connected to one end of the connecting bracket, a T-shaped screw fixedly installed on the outer side of the vertical shaft, the T-shaped screw being inserted into the inside of the limit groove, the limit groove being opened on the outer side of the disc seat, a nut engaging with the T-shaped screw, and an angle gauge opened on the surface of the disc seat.

[0006] As a further preferred embodiment of this technical solution, the outer side of the vertical shaft abuts against the inner wall of the built-in annular groove, and the limiting plate abuts against the surface of the disc seat.

[0007] As a further preferred embodiment of this technical solution, the outer side of the T-shaped screw abuts against the inner wall of the limiting groove, the nut is tightly attached to the outer side of the disc seat, and the angle scale is evenly distributed on the surface of the disc seat.

[0008] As a further preferred embodiment of this technical solution, the outer side of the nut is provided with anti-slip grooves, which are evenly distributed on the outer side of the nut, and the thread connecting the T-shaped screw and the nut is a fine-pitch thread.

A bushing is fixedly installed on the fixing frame, and a threaded hole is opened on the outer side of the bushing, and a threaded rod is engaged in the threaded hole.

[0010] As a further preferred embodiment of this technical solution, the threaded hole is vertically arranged on the outer side of the bushing, and a protective block is provided inside the threaded hole, which is fixedly arranged on the bottom end of the threaded rod.

[0011] As a further preferred embodiment of this technical solution, the fastener is composed of a bolt and a nut, with the end of the bolt passing through the frame and the fixing frame and engaging with the nut.

[0012] This utility model provides a pipe bending machine for processing stainless steel grooved pipe fittings, which has the following beneficial effects:

[0013] This utility model utilizes the interlocking mechanism between the built-in annular groove on the outer side of the disc base and the angle gauge. When the operator moves the connecting bracket, the vertical shaft can slide within the built-in annular groove, and the T-shaped screw can move within the limiting groove. This allows for adjustment and positioning of the required bending angle of the pipe fitting. Subsequently, by rotating the nut outside the T-shaped screw, the nut can be tightly attached to the outer side of the disc base, allowing the operator to directly bend the pipe fitting.

[0014] This utility model allows personnel to insert the pipe fitting into the inside of the bushing, and then rotate the threaded rod to compress the outside of the pipe fitting, thereby fixing the pipe fitting inside the bushing, which facilitates subsequent bending work on the pipe fitting.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a pipe bending machine for processing stainless steel grooved pipe fittings includes a bending machine body 1. The bending machine body 1 includes a frame body 2. A disc seat 3 is fixedly installed on the outer side of the frame body 2. A central shaft 4 is fixedly installed on the disc seat 3. A base 5 is fixedly installed at the bottom end of the central shaft 4. A connecting bracket 6 is rotatably connected to the base 5. An internal annular groove 7 is formed on the disc seat 3. A vertical shaft 8 is inserted into the internal annular groove 7. Limit plates 9 are fixedly installed at the top and bottom ends of the vertical shaft 8, respectively. A limiting plate 9 is fixedly connected to one end of a connecting bracket 6. A T-screw 10 is fixedly installed on the outer side of the vertical shaft 8. The T-screw 10 is inserted into the inside of a limiting groove 11, which is located on the outer side of the disc seat 3. A nut 12 is engaged with the T-screw 10. An angle gauge 13 is provided on the surface of the disc seat 3. Through the cooperation between the built-in annular groove 7 on the outer side of the disc seat 3 and the angle gauge 13, the vertical shaft 8 can be positioned inside the built-in annular groove 7 when the connecting bracket 6 is moved by the operator. The sliding T-screw 10 moves within the limiting groove 11, allowing adjustment and positioning of the required bending angle of the pipe fitting. Then, the nut 12 rotates outside the T-screw 10, ensuring it fits snugly against the outer side of the disc seat 3, allowing for direct bending of the pipe fitting. The outer side of the vertical shaft 8 abuts against the inner wall of the built-in annular groove 7, and the limiting plate 9 abuts against the surface of the disc seat 3, facilitating the adjustment of the vertical shaft 8's position. The outer side of the T-screw 10 abuts against the inner wall of the limiting groove 11, and the nut 12 rotates outside the T-screw 10. 2. The angle gauge 13 is evenly distributed on the surface of the disc seat 3, closely attached to the outer side of the disc seat 3. As the nut 12 is tightened onto the outer side of the T-screw 10, the position of the vertical shaft 8 can be quickly fixed. The outer side of the nut 12 is provided with anti-slip texture 14, which is evenly distributed on the outer side of the nut 12. The thread connecting the T-screw 10 and the nut 12 is a fine thread. The anti-slip texture 14 facilitates the rotation of the nut 12 by personnel, and the fine thread provides self-locking stability.

[0022] like Figure 1 and Figure 4As shown, a fixing frame 15 is provided on the frame body 2. The fixing frame 15 and the frame body 2 are fixedly connected by fasteners 16. A bushing 17 is fixedly installed on the fixing frame 15. A threaded hole 18 is opened on the outer side of the bushing 17. A threaded rod 19 is engaged in the threaded hole 18. Personnel can insert the pipe into the bushing 17. Then, by rotating the threaded rod 19, the threaded rod 19 can compress the outer side of the pipe, thereby fixing the pipe inside the bushing 17. This facilitates subsequent bending work on the pipe fittings. The threaded hole 18 is vertically arranged on the outside of the bushing 17. A protective block 20 is provided inside the threaded hole 18. The protective block 20 is fixedly arranged on the bottom end of the threaded rod 19. The protective block 20 can prevent the pipe fitting from being squeezed. The fastener 16 is composed of a bolt and a nut. The end of the bolt passes through the frame 2 and the fixing frame 15 and engages with the nut to effectively fix the position of the fixing frame 15.

[0023] This utility model provides a pipe bending machine for processing stainless steel grooved pipe fittings. The specific working principle is as follows:

[0024] In use, the operator inserts the pipe into the bushing 17 and then rotates the threaded rod 19. The protective block 20 fixed at the end of the threaded rod 19 then compresses the outside of the pipe, thus fixing the pipe inside the bushing 17. Before bending the pipe, the operator rotates the connecting bracket 6, causing the vertical shaft 8 to slide inside the built-in annular groove 7 and the T-shaped screw 10 to move inside the limiting groove 11. This allows for adjustment and positioning of the required bending angle of the pipe. Then, by rotating the nut 12 outside the T-shaped screw 10, the nut 12 can be tightly attached to the outside of the disc seat 3, allowing the operator to directly bend the pipe.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
