Description

Technical Field

[0001] The invention belongs to the technical field of oil pipe bending equipment and relates to an engine supercharger oil return pipe bending and forming processing equipment. Background Art

[0002] The engine oil line transports engine oil, helping to lubricate and cool various engine components, thereby ensuring the proper operation and performance of the vehicle. Oil lines are typically made of heat- and pressure-resistant materials such as rubber, steel, or composite materials. The interior of the oil line is typically smooth to reduce resistance to oil flow and enhance lubrication.

[0003] Before assembly, engine oil pipes must be bent using bending equipment into a shape that matches the vehicle's vehicle model. The appropriate bending method is selected based on the material's properties, typically cold bending, hot bending, and CNC bending. Currently, metal alloys are the most commonly used materials, typically bent using a pipe bender, which is suitable for rapid, mass production. While current pipe benders are capable of performing multiple, automated bends in a single pass and can also bend at multiple angles in three dimensions, many still require significant manual intervention or assistance during loading and unloading, as well as for positioning and clamping the pipe. These procedures include manual workpiece placement, initiation of the positioning and clamping process, and manual removal of the finished product. This frequent need for manual intervention before and after the bending process not only hinders further improvements in production efficiency but also increases operator workload, particularly in high-speed, high-volume production scenarios. Therefore, we propose a bending and forming machine for engine supercharger return oil pipes to address these challenges. Summary of the Invention

[0004] In view of this, the present invention provides an engine supercharger return oil pipe bending and forming processing equipment to solve the problem that traditional bending equipment requires manual cooperation in loading and unloading throughout the process, which is not only time-consuming and labor-intensive, but also has low work efficiency.

[0013] Furthermore, the horizontal strips and the vertical strips are connected with each other in a damping sliding manner.

[0025] The following describes the embodiments of the present invention by means of specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] Example 1: Figure 1-Figure 5As shown, the engine supercharger return oil pipe bending and forming processing equipment includes a work surface 1, an L-shaped mounting frame 4 and a sliding seat 7. The four corners of the bottom of the work surface 1 are fixedly connected to support legs 2, the top side of the work surface 1 is fixedly connected to the L-shaped mounting frame 4, the bottom of the L-shaped mounting frame 4 is slidably connected to the sliding seat 7, and one side of the L-shaped mounting frame 4 is fixedly connected to a screw motor 5. The bottom side of the L-shaped mounting frame 4 is fixedly connected to a fixed block 11. The fixed block 11 and the L-shaped mounting frame 4 are rotatably connected to the same screw rod 12, and the sliding seat 7 is threadedly sleeved on the screw rod 12. The output shaft of the screw motor 5 rotates through one side of the L-shaped mounting frame 4 and is fixedly connected to one end of the screw rod 12. Starting the screw motor 5 to drive the screw rod 12 to rotate can drive the sliding seat 7 to move back and forth at the bottom of the L-shaped mounting frame 4.

[0027] The processing equipment also includes a bending mechanism located on one side of the top of the work surface 1 for bending the oil pipe. The bending mechanism includes a positioning post 8 extending through the top of the work surface 1. The bottom end of the positioning post 8 extends downward and is fixedly connected to a base plate 10, which is connected to the work surface 1. The outer wall of the positioning post 8 is movably sleeved with a sleeve 13 that extends through the top of the work surface 1. The top end of the sleeve 13 is fixedly connected to a bending rod 17 that cooperates with the positioning post 8. The work surface 1 is provided with a drive element for rotating and adjusting the sleeve 13 up and down. The oil pipe is positioned by the positioning post 8, and the rotation of the sleeve 13 then drives the bending rod 17 to rotate, thereby achieving bending and forming the oil pipe. At the same time, by adjusting the up and down movement of the sleeve 13, it can cooperate with the positioning post 8 to achieve bending of the oil pipe in different directions, thereby improving the bending flexibility and enabling bending and forming of oil pipes with different bending angles.

[0028] In one aspect of this embodiment, the driving member includes a servo motor 15 fixedly connected to the top of the work surface 1 and a second cylinder 18. The output shaft of the servo motor 15 rotates and passes through the bottom of the work surface 1 and is fixedly sleeved with a long gear 21. The outer wall of the sleeve 13 is located on the side below the work surface 1 and is fixedly sleeved with an external gear disc 19 that meshes with the long gear 21. The outer wall of the sleeve 13 is rotatably sleeved with a lifting sleeve 16 located below the external gear disc 19. The output end of the second cylinder 18 passes through the bottom of the work surface 1 and is fixedly connected to the top side of the lifting sleeve 16. When the servo motor 15 is started, the sleeve 13 can be driven to rotate in the lifting sleeve 16 through the meshing movement of the long gear 21 and the external gear disc 19. Since the oil pipe is positioned in the groove at the top of the positioning column 8, the sleeve 13 rotates and drives the bending rod 17 to rotate. When the sleeve 13 contacts the oil pipe, the oil pipe is bent. In addition, the servo motor 15 and the second cylinder 18 are both set through the control system. When the oil pipe needs to be reverse bent, the second cylinder 18 is activated to drive the lifting sleeve 16 downward, which can drive the sleeve 13 downward and the bending rod 17 downward so that its top is lower than the oil pipe. When the sleeve 13 moves downward, it also drives the outer gear plate 19 downward. Due to the long gear 21, the outer gear plate 19 can always remain in meshing state with the long gear 21. Therefore, after the sleeve 13 drives the bending rod 17 downward, the servo motor 15 is activated again and drives the bending rod 17 to rotate to the other side of the oil pipe through the sleeve 13. After adjusting the position of the bending rod 17, the second cylinder 18 is activated again and drives the sleeve 13 upward through the lifting sleeve 16, which in turn drives the bending rod 17 upward. The servo motor 15 is then activated to drive the bending rod 17 to rotate in the opposite direction, thereby achieving the effect of reverse bending the oil pipe.

[0029] The present invention can be used in the field of engine supercharger oil return pipe bending and forming processing equipment, and can also be applied to other fields of the present invention.

[0030] Example 2: This example is a further improvement of the previous example: Figure 1-Figure 5 As shown, a triangular platform 6 is provided on one side of the top of the work surface 1. The top of the sleeve 13 passes through the top of the triangular platform 6 and is provided with an inclined surface flush with the inclined surface of the triangular platform 6. The top of the positioning column 8 extends to the top of the triangular platform 6. Two first cylinders 14 are symmetrically fixedly connected to the bottom of the work surface 1, and the output ends of the two first cylinders 14 are fixedly connected to the top of the base plate 10. A collection box 3 used in conjunction with the triangular platform 6 is placed on one side of the work surface 1. When the oil pipe processing is completed, the two first cylinders 14 can be started to drive the base plate 10 to move downward, which can drive the positioning column 8 to move downward in the sleeve 13, as shown in FIG. Figure 10As shown, when the top end of the positioning column 8 moves to the top end of the sleeve 13, the first cylinder 14 stops working. At this time, the bent oil pipe will be completely on the inclined surface at the top of the triangular table 6. Without any obstruction, the oil pipe will slide downward on the inclined surface under its own gravity and directly slide into the collection box 3 below for centralized collection, thereby completing the automatic unloading and collection of the oil pipe. There is no need for manual unloading, which reduces the labor intensity.

[0031] In one aspect of this embodiment, two guide rods 20 are symmetrically fixedly connected to the top of the lifting sleeve 16. The top ends of the two guide rods 20 penetrate the top of the work surface 1 and extend into the interior of the triangular platform 6. The top of the triangular platform 6 is symmetrically provided with two guide holes 61 that plug into and mate with the corresponding guide rods 20. The limited sliding of the guide rods 20 within the guide holes 61 can improve the stability of the vertical movement of the lifting sleeve 16. In addition, the provision of the two guide rods 20 allows the triangular platform 6 to be directly positioned and flexibly sheathed on the work surface 1, eliminating the need for additional fixing of the triangular platform 6. This ensures the stable use of the triangular platform 6 and facilitates its removal, thereby improving its flexibility.

[0032] Example 3: This example is a further improvement of the previous example: Figure 1-Figure 5As shown, the processing equipment also includes a positioning mechanism located above the work surface 1 and connected to the bending mechanism. This mechanism is used to position and support the oil pipe, and the positioning mechanism works in conjunction with the sliding seat 7 to automatically clamp the oil pipe and simultaneously bend and transport the oil pipe. The positioning mechanism includes a vertical strip 9 that extends through and slides on the top of the work surface 1. The bottom end of the vertical strip 9 is fixedly connected to the top of the base plate 10. A horizontal strip 27 is slidably connected to the top of one side of the vertical strip 9. The side of the horizontal strip 27 near the positioning column 8 is fixedly connected to a positioning seat 22 that fits against one side of the vertical strip 9. The positioning seat 22 cooperates with the positioning column 8 to position and place the oil pipe, and the positioning seat 22 cooperates with the sliding seat 7 to clamp and transport the oil pipe. The horizontal strip 27 is connected to the vertical strip 9 in a damped sliding manner. When the first cylinder 14 is activated to drive the base plate 10 up and down, it will drive the positioning column 8 and the vertical strip 9 to move up and down synchronously, thereby driving the positioning seat 22 up and down. When the positioning column 8 moves downward to the top of the sleeve 13 and is in a discharging state, it will not hinder the downward movement of the positioning seat 22. When the positioning seat 22 moves up and docks with the sliding seat 7, the positioning column 8 moves up synchronously to ensure the normal support of the oil pipe. After the positioning seat 22 docks with the sliding seat 7, it can automatically complete the clamping and fixing of one end of the oil pipe, and start the screw motor 5 to drive the sliding seat 7 to move, which can also drive the positioning seat 22 to move, and then drive the oil pipe to be transported and complete the bending. During the movement of the positioning seat 22, the horizontal strip 27 will be driven to slide in the vertical strip 9. Within the maximum travel of the sliding seat 7, the horizontal strip 27 will not be separated from the sliding between the vertical strip 9, ensuring the stability of the movement of the positioning seat 22. At the same time, through the sliding cooperation between the horizontal strip 27 and the vertical strip 9, the positioning seat 22 can be driven to move up and down synchronously by the horizontal strip 27 during the up and down movement of the vertical strip 9. The damped sliding between the horizontal strips 27 and the vertical strips 9 can make the vertical strips 9 drive the positioning seat 22 to move up and down more stable, preventing the positioning seat 22 from moving and affecting the positioning of the oil pipe. Furthermore, in order to further stabilize the positioning seat 22, in addition to adopting damping measures, magnetic attraction between a magnet and a metal block can also be used to ensure that the positioning seat 22 is stably adsorbed on the vertical strips 9.

[0033] In one aspect of this embodiment, a positioning groove 221 is provided at the top of the positioning seat 22. Two clamping blocks 23 are symmetrically and slidably connected inside the positioning groove 221. The two clamping blocks 23 are fixedly connected to the first slide bar 24 on the side away from each other. The ends of the two first slide bars 24 that are away from each other pass through one side of the positioning seat 22 and extend outward. The outer walls of the two first slide bars 24 are sleeved with a first spring 25, and the two ends of the first spring 25 are respectively fixedly connected to the end of the first slide bar 24 away from the clamping block 23 and the side of the positioning seat 22. A positioning notch 222 connected to the positioning groove 221 is provided on the side of the top of the positioning seat 22 away from the vertical strip 9. Figure 1As shown, the height of the positioning seat 22 and the positioning column 8 are first adjusted to the position of the loading state, that is, the positioning seat 22 is not connected to the sliding seat 7, and the positioning column 8 is not fully extended to the top of the sleeve 13. At this time, an oil pipe is clamped from the material area by a robot, and then placed in the positioning notch 222 of the positioning seat 22 and the groove at the top of the positioning column 8, and one end of the oil pipe is located in the positioning groove 221 and conflicts with the inner wall of the positioning groove 221, thereby completing the positioning support placement of the oil pipe.

[0034] Example 4: This example is a further improvement of the previous example: Figures 1-8 As shown, the bottom of the sliding seat 7 is symmetrically defined with two bottom grooves 71, each of which is provided with a movable block 28. The bottoms of the two movable blocks 28 are symmetrically defined with docking grooves 281, and the inner walls of the two docking grooves 281 facing away from each other are provided with inclined surfaces. The tops of the two clamping blocks 23 are fixedly connected with a stopper 26 that cooperates with the inclined surfaces of the docking grooves 281. The top walls of the two docking grooves 281 are provided with a slot 282 that cooperates with the corresponding stopper 26. A limit assembly is provided within the sliding seat 7 for simultaneous use with the two movable blocks 28, and the limit assembly intermittently interferes with the vertical strip 9. When the vertical strip 9 drives the positioning seat 22 to move upward, it also drives the clamping block 23 and the stop block 26 to move upward. When the top end of the stop block 26 extends into the bottom groove 71, it also extends into the docking groove 281 and first contacts the inclined surface of the docking groove 281. As the positioning seat 22 continues to move upward, the stop block 26 also continues to move upward along the inclined surface. At the same time, it drives the clamping block 23 to move along the inclined surface, and the two clamping blocks 23 move closer to each other. The clamping block 23 also drives the first slide bar 24 to move and compress the first spring 25. When the stop block 26 corresponds to the slot 282, the oil pipe is clamped and fixed. The stop block 26 continues to move toward the upper limit in the slot 282 until the positioning seat 22 and the sliding seat 7 are connected. After the connection is complete, the screw motor 5 is started to rotate the screw 12 and drive the sliding seat 7 to move toward the positioning column 8. Then, the stop block 26 can be adapted and engaged in the slot 282, and the positioning seat 22 can be moved synchronously by the movable block 28, thereby completing the automatic clamping and transportation of the oil pipe. In order to facilitate the protection and clamping of the oil pipe, rubber pads can be provided on the side where the two clamping blocks 23 are close to each other.

[0035] In one aspect of this embodiment, the limiting assembly includes a cavity 72 opened inside the sliding seat 7, and the inner wall of the cavity 72 on the side away from the movable block 28 is penetrated by a pull rod 30 for sliding connection, and the end of the pull rod 30 located inside the cavity 72 is fixedly connected to a connecting head 31, and the outer wall of the connecting head 31 is symmetrically fixedly connected with two L-shaped push rods 32, and one end of the two L-shaped push rods 32 extends into the two bottom grooves 71 respectively and conflicts with the side of the two movable blocks 28 away from each other. The top edge of the side of the two movable blocks 28 close to the cavity 72 is provided with symmetrically arranged triangular notches 283, and one end of the two L-shaped push rods 32 intermittently conflicts with the inclined surfaces of the corresponding triangular notches 283, and the side of the two movable blocks 28 away from each other is symmetrically fixed with two second sliding rods 29, and the other ends of the four second sliding rods 29 pass through the corresponding side of the sliding seat 7 and extend outward. The end of the pull rod 30 away from the connector 31 extends outward and is fixedly connected to a limit block 34 that intermittently contacts the vertical strip 9. A second spring 33 is sleeved on the outer wall of one side of the pull rod 30 located in the cavity 72, and the two ends of the second spring 33 are respectively fixedly connected to the inner wall of one side of the cavity 72 and one side of the connector 31. The elastic force of the second spring 33 is less than the elastic force of the first spring 25. First, the movable block 28 is contacted by the L-shaped push rod 32. In the contact state, the side of the movable block 28 away from the second slide bar 29 contacts the inner wall of the bottom groove 71, so that the movable block 28 is in a limited state in the bottom groove 71. During the upward movement of the push block 26, the movable block 28 will not be driven to move, thereby ensuring normal clamping of the oil pipe. In addition, during the movement of the sliding seat 7 and the movement of the positioning seat 22, the oil pipe is always clamped. After the oil pipe is bent, the sliding seat 7 has not yet reached its maximum travel range, and the sliding seat 7 drives the limit block 34 through the pull rod 30 to just contact the top of the side of the vertical strip 9 away from the positioning seat 22. Then, the sliding seat 7 can be driven to move a short distance by starting the screw motor 5. During the movement, the limit block 34 is restrained by the vertical strip 9 and will not move further, thereby driving the pull rod 30 to remain stationary, and the connector 31 and the two L-shaped support rods 32 also remain stationary. As the sliding seat 7 continues to move, the second spring 33 is compressed, and the two movable blocks 28 move with the sliding seat 7 and are released from the limited contact with the L-shaped support rod 32, so that one end of the L-shaped support rod 32 is located at a position corresponding to the triangular notch 283. At this point, the first spring 25 forces the clamping block 23 to reset, while the stop block 26 drives the movable block 28 to move, moving the two movable blocks 28 away from each other and causing one end of the L-shaped stop rod 32 to contact the slope of the triangular notch 283, thereby automatically releasing the oil pipe from the clamp. The lead screw motor 5 is then restarted, driving the sliding seat 7 to reset, and simultaneously driving the positioning seat 22 to reset.After the sliding seat 7 and the positioning seat 22 are fully reset, the first cylinder 14 is activated to drive the bottom plate 10 downward, simultaneously driving the positioning column 8, the vertical strip plate 9, and the positioning seat 22 downward and into a discharge state, so that the processed oil pipe automatically slides through the inclined surface of the triangular table 6 into the collection box 3. After the positioning seat 22 moves downward, it also drives the clamping block 23 and the stop block 26 downward. Because the elastic force of the second spring 33 is less than the elastic force of the first spring 25, when the oil pipe is released and reset, it does not push the movable block 28 to move, and thus does not clamp the oil pipe again, ensuring the normal reset of the entire device. After the block 26 is separated from the docking with the movable block 28, the elastic force of the second spring 33 will drive the pull rod 30 to reset and move, and drive the two L-shaped block rods 32 to move through the connecting head 31. By cooperating with the inclined surface of the triangular notch 283, the two movable blocks 28 can be pushed closer to each other again. When the movable block 28 again contacts the inner wall of the bottom groove 71, one end of the L-shaped block rod 32 will also contact one side of the movable block 28 again, thereby completing the automatic limiting of the movable block 28, which is convenient for the next automatic clamping of the oil pipe.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the screw motor 5, the first cylinder 14, the servo motor 15 and the second cylinder 18 are commonplace, and are all conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
