Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a straight pipe diameter reduction processing equipment for automotive parts processing. Background Technology

[0002] In automotive piping systems, reducers are required for various aspects such as oil transportation and exhaust. Reducers serve to connect, control, change direction, divert flow, seal, and support components in the piping system. Generally, reducers are heated red-hot by a heater, removed using a clamp, and then punched using a conical die.

[0003] According to CN114273540A, a straight pipe diameter reduction processing device for automotive parts includes a processing table. A controller and a bearing seat plate are mounted on the processing table. The controller is fixedly connected to the center of the front of the processing table. The bearing seat plates are fixedly connected to the left and right sides of the upper surface of the processing table. The left bearing seat plate is connected to a diameter reduction mechanism via a servo motor, and the right bearing seat plate is connected to a fixed frame via a drive motor. An electric push rod is mounted on the fixed frame. The electric push rod is connected to an arc-shaped plate via a push rod. A first pressure sensor is fixedly connected to the center of the arc-shaped plate. The output end of the servo motor is connected to a driven gear via a driving gear. This invention enables automatic face-changing of straight pipe fittings during diameter reduction, avoiding damage caused by uneven stress during the process and improving the uniformity of diameter reduction processing equipment. However, this device still has some problems: the end-fixing method for fixing the straight pipe fittings results in unstable positions due to the length of the pipe fittings, and it cannot quickly switch between ends. To address these issues, we propose a straight pipe fitting diameter reduction processing equipment for automotive parts manufacturing. Utility Model Content

[0016] This utility model provides a straight pipe diameter reduction processing equipment for automotive parts processing, which has the following features:

[0017] Beneficial effects:

[0018] This invention involves placing a straight tube inside an annular sleeve, then using an adjustment mechanism to drive a diameter-changing mechanism to move. This allows the punching head to move the end of the straight tube, aligning the straight tube and the annular sleeve vertically, thus positioning the straight tube. Subsequently, a cylinder drives a protective plate to move, and a rubber seat secures the straight tube, facilitating the diameter-changing mechanism's work. A servo motor then drives a rotating shaft to rotate, allowing for the switching between different lengths of the straight tube. This structure improves the stability of the straight tube's position and can secure tubes of varying lengths.

[0019] This utility model, through the provision of a diameter-changing mechanism, allows the electric heating rod to heat the outside of the straight pipe body when the end of the straight pipe body is inside the sleeve. Subsequently, the cylinder drives the punch head to move, allowing the punch head to slowly penetrate into the straight pipe body, thereby changing the diameter of the end of the straight pipe body. Furthermore, the punch head can be replaced according to the different diameters of the straight pipe body.

[0020] This utility model features an adjustment mechanism. When a straight pipe is placed inside the annular sleeve, a servo motor drives a threaded rod to rotate, causing a moving block to move inside the limiting groove and outside the threaded rod. This, in turn, moves the side plate, allowing the punching head to push the end of the straight pipe, indirectly positioning the center of the straight pipe inside the annular sleeve. This positions the straight pipe for subsequent fastening and diameter adjustment. Furthermore, the adjustment mechanism can drive the diameter adjustment mechanism to move without affecting the fastening mechanism's adjustment of the straight pipe's position.

Detailed Implementation

[0027] 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.

[0028] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, a straight pipe diameter-changing processing device for automotive parts includes a base 1, a straight pipe body 2 disposed on the base 1, a fastening mechanism 3 disposed on the surface of the base 1 for fastening the position of the straight pipe body 2, and the fastening mechanism 3 can realize the position adjustment function of the straight pipe body 2, a diameter-changing mechanism 4 disposed on the surface of the base 1 for realizing the diameter-changing function of the end of the straight pipe body 2, and an adjusting mechanism 5 disposed on the base 1 for pushing the diameter-changing mechanism 4 to a certain position. After the straight pipe body 2 is placed inside the annular sleeve 8, the adjusting mechanism 5 drives the diameter-changing mechanism 4 to move. The stamping head 20 can move the end of the straight tube 2, so that the straight tube 2 and the annular sleeve 8 are on the same vertical line, that is, the position of the straight tube 2 is positioned. Then, the cylinder 14 drives the guard plate 15 to move, and the rubber seat 16 can fasten the position of the straight tube 2, thereby facilitating the diameter changing mechanism 4 to change the diameter of the straight tube 2. Subsequently, the servo motor 6 can drive the rotating shaft 7 to rotate, so that the ends of the straight tube 2 can be switched. This structure can improve the stability of the position of the straight tube 2 and can fasten the straight tube 2 of different lengths.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the fastening mechanism 3 includes a servo motor 6, which is fixedly mounted on the lower surface of the base 1. A rotating shaft 7 is fixedly connected to the end of the rotating shaft of the servo motor 6. An annular sleeve 8 is fixedly connected to the top of the rotating shaft 7. A straight tube 2 is inserted into the annular sleeve 8. The outer side of the straight tube 2 abuts against a limit block 9. A U-shaped frame 10 is fixedly connected to the outer side of the limit block 9. The U-shaped frame 10 and the annular sleeve 8 are slidably connected. A square plate 11 is fixedly mounted on the U-shaped frame 10. A screw 12 is engaged with the square plate 11. One end of the 12 is rotatably connected to the outer block 13, which is fixedly installed on the outside of the annular sleeve 8. A cylinder 14 is fixedly installed on the annular sleeve 8, and a protective plate 15 is fixedly connected to the telescopic rod of the cylinder 14. A rubber seat 16 is fixedly installed inside the protective plate 15, and the rubber seat 16 is tightly attached to the outside of the annular sleeve 8. A scale 17 is provided on the outside of the U-shaped frame 10. With the fastening mechanism 3, as the personnel place the straight tube 2 inside the annular sleeve 8, the straight tube 2 can slide against the outside of the limiting block 9, thereby allowing the straight tube 2 to... The rubber seat 16 is stably positioned inside the annular sleeve 8. Subsequently, the protective plate 15 is moved by the cylinder 14, allowing the rubber seat 16 to be tightly secured against the outside of the straight tube 2. After one end of the straight tube 2 changes diameter, the rotating shaft 7 is rotated by the servo motor 6, thus completing the position change of both ends of the straight tube 2 and the meshing connection between the square plate 11 and the screw 12. This allows the limiting block 9 to be positioned within the annular sleeve 8 for adjustment, enabling positional securing of straight tubes 2 with different diameters. Two limiting blocks 9 are provided. The limiting blocks 9 are symmetrically arranged on the ends of the U-shaped frame 10. The U-shaped frame 10 and the square plate 11 are connected by fine-tooth thread, which can effectively limit the position of the straight pipe 2. The fine-tooth thread has self-locking stability. The outer part of the limiting block 9 is spherical. The rubber seat 16 is located at the center of the annular sleeve 8. The lower surface of the rubber seat 16 is wavy, so that when the straight pipe 2 is inside the annular sleeve 8, the straight pipe 2 can slide against the outer side of the limiting block 9 and the rubber seat 16 can effectively fasten the position of the straight pipe 2.

[0030] like Figure 1 and Figure 4As shown, the diameter-changing mechanism 4 includes a side plate 18, which is located on the upper surface of the base 1. A circular hole 19 is provided on the outer side of the side plate 18, and a punch head 20 is inserted into the circular hole 19. The punch head 20 is fixedly connected to the telescopic end of the cylinder 21. The cylinder 21 is fixedly mounted on the outer side of the side plate 18 by a bracket. A sleeve 22 is fixedly installed on the outer side of the side plate 18, and an electric heating rod 23 is fixedly installed inside the sleeve 22. With the provided diameter-changing mechanism 4, when the end of the straight tube 2 is inside the sleeve 22, the electric heating rod 23 can heat the outside of the straight tube 2. Then, the cylinder 21 drives the punch head 20 to move, so that the punch head 20 can slowly penetrate into the straight tube 2, thereby changing the diameter of the end of the straight tube 2. The punch head 20 can be replaced according to the different diameters of the straight tube 2.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the adjustment mechanism 5 includes a moving block 24 and a slider 25. Both the moving block 24 and the slider 25 are fixedly mounted on the bottom of the side plate 18. The moving block 24 and the slider 25 are respectively inserted into the limiting groove 26 and the sliding groove 27. The limiting groove 26 and the sliding groove 27 are formed on the upper surface of the base 1. A threaded rod 28 is rotatably connected within the limiting groove 26. One end of the threaded rod 28 is fixedly mounted on the rotating shaft of a second servo motor 29. The second servo motor 29 is fixedly mounted on the outside of the base 1. The moving block 24 and the threaded rod 28 are meshed together. Through the adjustment mechanism 5, when a person places the straight pipe 2 inside the annular sleeve 8, the second servo motor 29 drives the threaded rod 28 to rotate, causing... The movable block 24 moves inside the limiting groove 26 and outside the threaded rod 28, thereby driving the side plate 18 to move in position. That is, the punch head 20 can push the end of the straight tube 2, indirectly placing the center of the straight tube 2 inside the annular sleeve 8, thereby positioning the straight tube 2 to facilitate subsequent fastening and diameter changing work. The adjusting mechanism 5 can drive the diameter changing mechanism 4 to move without affecting the adjustment of the straight tube 2 position by the fastening mechanism 3. Two sets of sliders 25 are provided, and the two sets of sliders 25 are symmetrically distributed at the bottom of the side plate 18. By providing sliders 25, the position of the moving side plate 18 can be restricted.

[0032] This utility model provides a straight pipe diameter reduction processing equipment for automotive parts processing, the specific working principle of which is as follows:

[0033] During use, the operator places the straight tube 2 inside the annular sleeve 8, allowing the straight tube 2 to slide against the outside of the limiting block 9. Then, the servo motor 29 drives the threaded rod 28 to rotate, causing the moving block 24 to move inside the limiting groove 26 and outside the threaded rod 28. This moves the side plate 18, allowing the punch head 20 to push the end of the straight tube 2, indirectly positioning the center of the straight tube 2 inside the annular sleeve 8. Afterwards, the cylinder 14 drives the protective plate 15 to move, allowing the rubber seat 16 to tighten. The sleeve 23 is attached to the outside of the straight tube 2 and fastened. As the end of the straight tube 2 is inside the sleeve 22, the electric heating rod 23 can heat the outside of the straight tube 2. Then, the cylinder 21 drives the punch head 20 to move, so that the punch head 20 can slowly penetrate into the straight tube 2, thereby changing the diameter of the end of the straight tube 2. Then, the adjusting mechanism 5 drives the diameter changing mechanism 4 to reset. Then, the servo motor 6 drives the rotating shaft 7 to rotate, thus completing the position conversion of the two ends of the straight tube 2, thereby completing the diameter change of the two ends of the straight tube 2.
