[0002] In the pipe processing process, there is a special type of pipe that requires the ends of a hollow pipe with an overall C-shaped structure to be extruded into a circular structure from a waist-shaped structure in order to meet special assembly requirements later.

[0003] To meet this specific processing requirement, existing automated extrusion molding equipment is unable to complete it. Current processing methods typically employ semi-automated operations, which not only result in low processing efficiency but also compromise processing accuracy, affecting the subsequent assembly results. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic extrusion molding device for pipe ends. By setting contour grooves in the upper and lower molds of the extrusion molding component for positioning, and by quickly completing the extrusion molding through the molding grooves set on the molding plate, the entire molding process is automated.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] An automatic extrusion forming device for pipe ends includes a machine base. A conveyor belt is disposed on the surface of the machine base. A pushing component is disposed on one side of the end of the conveyor belt, and an extrusion forming component is disposed on the other side.

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-8As shown, this utility model provides an automatic extrusion forming device for pipe ends, including a machine base 10. A conveyor belt 20 is provided on the surface of the machine base 10. A pushing component 30 is provided on one side of the end of the conveyor belt 20, and an extrusion forming component 40 is provided on the other side. The extrusion forming component 40 includes an upper die component 41 and a lower die component 42. The lower die component 42 includes a lower template 421, on which a pipe lower contour groove 4211 is provided. A lower forming plate 422 is provided on one side of the lower template 421, and a [missing information - likely a design feature] is provided on the lower forming plate 422. The upper mold assembly 41 includes an upper mold plate 411, the lower surface of which is connected to an upper forming plate 412. A positioning plate 413 that can move up and down relative to the upper forming plate 412 is provided below the upper forming plate 412. The lower surface of the positioning plate 413 is provided with an upper forming groove 4131 that corresponds to the position and shape of the lower forming groove 4211. The lower surface of the upper forming plate 412 is provided with an upper forming groove 4121 that corresponds to the position and shape of the lower forming groove 4221.

[0027] The pipe to be processed is moved to its end by the conveyor belt 20. The pusher assembly 30 pushes the pipe end into the extrusion forming assembly 40 until it is pushed into the lower pipe contour groove 4211 of the lower template 421. Then, the upper mold assembly 41 is controlled to gradually press down. During the pressing process, the pipe is first gradually inserted into the upper pipe contour groove 4131 on the positioning plate 413. The upper and lower pipe contour grooves 4131 and 4211 wrap and position the pipe, facilitating the subsequent end extrusion forming. After the positioning plate 413 and the lower template 421 have completed the positioning of the pipe, the upper mold assembly 41 continues to press down. At this time, the positioning plate 413 is not fixed, while the lower template 421 moves relative to the positioning plate 413 and continues to press down. The upper forming groove 4121 and the lower forming groove 4221 cooperate to complete the extrusion forming of the pipe end. After extrusion, the upper die assembly 41 is reset, and the material pusher assembly 30 is used to complete the unloading of the tube.

[0028] It should be noted that the depth of the lower profile groove 4211 of the pipe is relatively small. Only the initial positioning needs to be completed when the pipe is pushed in. After extrusion, the material can be easily pushed out of the lower profile groove 4211 of the pipe and discharged using the pusher assembly 30.

[0029] In this embodiment, the positioning plate 413 is provided with a plurality of demolding ejector pins 4132. The lower end of the demolding ejector pin 4132 can extend into the upper contour groove 4131 of the tube, and a buffer spring 4133 is provided between the upper end and the positioning plate 413. During the pressing down of the upper mold assembly 41, after the demolding ejector pin 4132 contacts the tube in the lower contour groove 4211, the buffer spring 4133 is gradually compressed. When the extrusion is completed, during the upward movement of the upper mold assembly 41, the elastic force of the buffer spring 4133 applies a downward force to the tube, ensuring that the extruded tube remains in the lower contour groove 4211, which facilitates subsequent ejection and unloading.

[0030] The lower die assembly 42 has a horizontally movable positioning baffle 70 on its side. Before the extrusion molding assembly 40 feeds material, the positioning baffle 70 is pushed to one side of the extrusion molding assembly 40. When the tube is pushed into the extrusion molding assembly 40 by the pusher assembly 30, the positioning baffle 70 limits and adjusts the tube to ensure it is pushed into place. The positioning baffle 70 can be designed with a suitable structure to accurately position the tube. In this embodiment, the positioning baffle 70 is designed with a stepped structure to accommodate positioning requirements.

[0031] A forming correction module 50 is also provided on the outer side of the extrusion molding assembly 40. The forming correction module 50 includes a forming head 51 that can move horizontally relative to the extrusion molding assembly 40. After the extrusion molding assembly 40 completes the extrusion of the pipe end, there may be cases where the end is not fully formed. By controlling the horizontal movement of the forming head 51 of the forming correction module 50 and inserting it into the end of the pipe, the forming part is shaped and corrected using its circular forming head 51, further improving the forming accuracy. In this embodiment, the front end of the forming head 51 is provided with an arc-shaped guide structure to facilitate its insertion into the forming end of the pipe.

[0032] A vibrating feeding box 60 is also provided on one side of the machine base 10. The discharge port of the vibrating feeding box 60 is connected to the conveyor belt 20. Limiting baffles 21 are provided on both sides of the conveyor belt 20, and the position of the limiting baffles 21 relative to the conveyor belt 20 is adjustable. The vibrating feeding box 60 completes the automatic feeding of pipes, and the feeding width can be adjusted as needed using the position-adjustable limiting baffles 21.

[0033] At the end of the conveyor belt 20, a proximity switch 22 electrically connected to the pushing assembly 30 is provided. When the proximity switch 22 is triggered, the pushing assembly 30 is controlled to push the tube at the end of the conveyor belt 20 into the extrusion molding assembly.

[0034] In summary, the automatic extrusion molding device for pipe ends provided by this utility model achieves automated operation of the entire molding process by setting contour grooves in the upper and lower molds of the extrusion molding component for positioning and quickly completing the extrusion molding through the molding grooves set on the molding plate.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
