Description

Technical Field

[0001] This utility model relates to the field of automotive control arm processing technology, specifically an automotive control arm bending device. Background Technology

[0002] The control arm is a key load-bearing and guiding component in the vehicle suspension system. It typically connects the vehicle body (or subframe) to the wheel steering knuckle. Bending (or shaping) the control arm is a crucial step in its manufacturing process, aiming to process the raw material into a complex shape that meets design requirements, thereby facilitating rapid improvement in vehicle manufacturing efficiency.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219786158U) discloses a bending device for manufacturing automotive control arms. The device includes a support base for holding the control arm to be bent. The support base has a bending groove for controlling the bending angle of the control arm. A top seat is positioned vertically above the bending groove. A pressure block is mounted on the top seat to press the control arm within the bending groove, thus bending the control arm. A power assembly for controlling the lifting and lowering of the top seat is located on the outer side of the support base. Subsequently, a first motor is activated, driving a first gear to rotate. Through the meshing of the first and second gears, a second gear rotates, causing a screw to rotate. As the screw rotates, a second support block moves up and down along the screw, causing the top seat to descend and press the pressure block into the bending groove, thereby bending the control arm within the groove. The overall mechanism is simple, easy to use, and can bend two control arms simultaneously, improving work efficiency.

[0004] Although the aforementioned patent improves the bending efficiency of the car control arm by setting up a support base, top seat, and power component, and by cooperating with each component, and by using the cooperation of the first motor, first gear, and second gear to facilitate bending of the control arm, after bending, the component still requires the operator to manually remove the car control arm. Due to the large size of the control arm, the operator needs to manually reach in to remove it. This operation increases the operator's operational risk and is not conducive to improving the processing efficiency of the control arm.

[0005] Therefore, this utility model provides an automotive control arm bending device to solve the above problems. Utility Model Content

[0006] This invention provides a bending device for an automotive control arm, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bending device for an automotive control arm includes a processing table, a support column fixedly connected to the lower bottom end of the processing table, and a discharge assembly provided at the upper top end of the processing table.

[0009] The discharge assembly includes a slide rod, the inner wall of which is rotatably connected to an abutment rod via a damping shaft. A bottom mold is installed at the top of the processing table, and a discharge seat is fixedly connected to the top of the bottom mold. An abutment rubber plate is fixedly connected to the outer wall of the discharge seat via a compression spring. An adjustment assembly is provided inside the bottom mold.

[0010] As a preferred technical solution of this application, the adjustment component includes a limiting slide groove formed at the top of the bottom mold, and a displacement seat is slidably connected to the inner wall of the limiting slide groove. Two displacement seats are threadedly sleeved on the outer wall of the bidirectional lead screw.

[0011] As a preferred technical solution of this application, a rotating sleeve is fixedly connected to the inner wall of the bottom mold, the end of the bidirectional lead screw rotates within the inner wall of the rotating sleeve, and a rotating handle is fixedly connected to the outer wall of the bidirectional lead screw.

[0012] As a preferred technical solution of this application, the lower bottom end of the displacement seat is rotatably connected to a buffer ball, the upper top end of the bottom mold is provided with an arc-shaped groove corresponding to the buffer ball, and the upper top end of the processing table is provided with a pressure mold assembly.

[0013] As a preferred technical solution of this application, the molding assembly includes a stand installed on the top of the processing table, a support plate installed on the inner wall of the stand, a hydraulic cylinder installed in the middle of the support plate, an upper mold installed at the output end of the hydraulic cylinder, and a sliding rod sliding inside the upper mold.

[0014] As a preferred technical solution of this application, a discharge rod is slidably connected to the upper top of the upper mold, a strong magnetic block is installed at the lower bottom of the discharge rod, and a handle is fixedly connected to the upper top of the discharge rod.

[0015] By setting up the ejection assembly, the processing efficiency of the automotive control arm can be improved and the operational risks for operators can be reduced through the cooperation of various components. Through the cooperation of the ejection seat, compression spring, and ejection plate, the control arm can be ejected after the upper die is bent by the compression spring and ejection plate. This avoids the dangerous operation of the operator manually reaching into the device to remove the control arm, which not only improves the operator's operational safety, but also improves the processing efficiency of the bending process through automatic ejection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a bending device for an automotive control arm, such as... Figures 1-4 As shown, the automobile control arm bending device includes a processing table 1, a support column is fixedly connected to the lower bottom end of the processing table 1, and a discharge component is provided at the upper top end of the processing table 1.

[0024] The discharge assembly includes a slide bar 2, the inner wall of which is rotatably connected to an abutment rod 4 via a damping shaft 3, a bottom mold 5 is installed on the top of the processing table 1, a discharge seat 6 is fixedly connected to the top of the bottom mold 5, and an abutment rubber plate 8 is fixedly connected to the outer wall of the discharge seat 6 via a compression spring 7. An adjustment assembly is provided inside the bottom mold 5.

[0025] The adjustment assembly includes a limiting groove 9 opened at the top of the bottom mold 5, and a displacement seat 10 is slidably connected to the inner wall of the limiting groove 9. The two displacement seats 10 are threadedly sleeved on the outer wall of the bidirectional lead screw 11.

[0026] A rotating sleeve 12 is fixedly connected to the inner wall of the bottom mold 5. The end of the bidirectional lead screw 11 rotates within the inner wall of the rotating sleeve 12. A throttle handle is fixedly connected to the outer wall of the bidirectional lead screw 11.

[0027] The bottom end of the displacement seat 10 is rotatably connected to a buffer ball 13, and the top end of the bottom mold 5 is provided with an arc-shaped groove corresponding to the buffer ball 13. The top end of the processing table 1 is provided with a pressure mold assembly.

[0028] The molding assembly includes a stand 14 mounted on the top of the processing table 1. A support plate 15 is mounted on the inner wall of the stand 14. A hydraulic cylinder 16 is mounted in the middle of the support plate 15. An upper mold 17 is mounted on the output end of the hydraulic cylinder 16, and a slide rod 2 slides inside the upper mold 17.

[0029] Specifically, the support column provides sufficient support for the processing table 1, ensuring its stability during the processing of the control arm. The discharge assembly, through the cooperation of various components, improves the processing efficiency of the control arm, avoiding the need for operators to insert their arms into the equipment to retrieve the control arm, thus reducing operational difficulty. Through the cooperation of the slide rod 2, damping shaft 3, and abutment rod 4, during the bending of the control arm by the hydraulic cylinder 16 as the upper mold 17 presses down, the abutment rod 4 is passively rotated on the inner wall of the slide rod 2 by the damping shaft 3 due to the abutment of the bottom mold 5 against the bottom mold 5. Then, when the support plate 15 and the upper mold 17 rise, the abutment rod 4 loses contact with the ejector plate 8, and the ejector plate 8 is released by the compression spring 7. The material properties quickly push the control arm out, and the discharge seat 6 can provide sufficient support and stability for the compression spring 7. After a single control arm is removed, the operator pulls up the slide bar 2, and the abutment rod 4 abuts against the upper mold 17 to automatically reset it to a vertical state and abut against the discharge plate 8 again. By adjusting the settings of the components, the two displacement seats 10 can be driven to move in opposite directions on the inner wall of the limiting slide groove 9 by rotating the bidirectional screw 11, which facilitates the processing of control arms of different sizes and improves the applicability of the device. The buffer ball 13 at the bottom of the displacement seat 10, in conjunction with the arc-shaped groove opened at the top of the bottom mold 5, can provide a certain buffer when the displacement seat 10 is moved, improving the smoothness of the adjustment.

[0030] The upper top of the upper mold 17 is slidably connected to the discharge rod 18, the lower bottom of the discharge rod 18 is equipped with a strong magnetic block 19, and the upper top of the discharge rod 18 is fixedly connected to a handle.

[0031] Specifically, the ejector rod 18, which slides at the top of the upper mold 17, can work with the strong magnetic block 19 to eject the metal control arm. After the control arm is ejected from the bottom mold 5 by the ejector plate 8, the strong magnetic block 19 at the bottom of the ejector rod 18 can attract the control arm with magnetic force, thereby sliding the ejector rod 18 to adjust the control arm to a position that is convenient for the operator to receive, further improving the processing efficiency of the control arm.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
