Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, in particular to a stamping and bending device for automobile parts. Background Art

[0002] As people's living standards improve, their consumption of automobiles is increasing. Auto parts are the basis of automobiles. There are many types of auto parts. During the production process, bending devices are needed to bend the parts for subsequent assembly and use.

[0003] Publication number "CN219253755U" discloses "a stamping and bending device for automobile parts". The device first places the pipe body into the arc groove, then moves the pipe body into the circular limit frame to limit one end of the pipe body. Then the first electric telescopic rod begins to extend or retract, driving the slider to move and realize the movement of the second frame. From then on, the bending position of the pipe body can be adjusted. When the pipe body is placed, the pipe body will first contact the surface of the third arc splint. At the same time, its spring will be under pressure, thereby When the third electric telescopic rod is extended, the first arc-shaped splint and the second arc-shaped splint are lowered to fit the outer surface of the pipe body, thereby limiting the pipe body for the second time. The pipe body is limited twice to prevent the pipe body from moving during the subsequent bending operation.

[0004] The above technical solution still has the following shortcomings during implementation:

[0005] When the pipe body is placed in the arc groove for limiting, under the elastic action of the spring, the third arc clamp first contacts the pipe body, and limits and clamps the two sides of the pipe body. It is not convenient to subsequently adjust the pipe body after limit clamping to move in the direction of the circular limit frame. At the same time, it is not convenient to adjust the movement of the second frame according to the bending position, which affects the limiting of the pipe and the implementation of the bending operation.

[0006] In response to the above problems, we propose a stamping and bending device for automobile parts. Utility Model Content

[0026] The arc groove is convenient for placing the pipe to be bent, and the limit frame 7 is combined with the first hydraulic rod 8 to limit one end of the pipe. At the same time, under the action of the first hydraulic rod 8, it is convenient to push the movable plate 9 to move downward, thereby driving the upper pressure plate 10 to move downward, pressing on the top of the pipe to limit the top of the pipe. Combined with the side clamping mechanism, it is convenient to limit and clamp both sides of the pipe, ensuring the stability of the pipe during the bending operation. The threaded cooperation between the screw rod 3 and the movable block 4 is convenient for adjusting the movable block 4 to move left and right. Under the action of the movable frame 5, it drives the upper pressure plate 10 and the side clamping mechanism to move left and right, so as to achieve the purpose of adjusting the bending position of the pipe. Combined with the mutual cooperation between the pointer 24 and the scale 23, it is convenient to control the moving distance of the upper pressure plate 10 and the side clamping mechanism, so as to accurately control the bending position of the pipe. At the same time, under the action of the hydraulic cylinder 6, it is convenient to push the limit frame 7 to the left and right, so as to push the bent pipe outward after the bending is completed, so as to facilitate the removal of the bent pipe.

[0027] The side clamping mechanism includes a folding bellows 11, a cylinder 12, a movable tube 13, an extrusion rod 14, an extrusion spring 15 and a side splint 16. The two cylinders 12 are relatively arranged on the movable frame 5. The upper ends of the two folding bellows 11 are respectively connected to the two sides of the bottom of the movable plate 9. The lower end of the folding bellows 11 is connected to the cylinder 12 through an air pipe. The movable tube 13 is movably matched with the inner cavity of the cylinder 12. The extrusion rod 14 is movably matched with the inner cavity of the movable tube 13, and the extrusion rod 14 is a T-shaped structure. The outer end of the extrusion rod 14 is fixedly connected to the side splint 16. The extrusion spring 15 is connected between the inner wall of the movable tube 13 and the extrusion rod 14. The end of the movable tube 13 is away from the side splint 16 A fixed limiting plate cooperates with the inner wall of the cylinder 12, and the folding bellows 11 is filled with air. The downward movement of the movable plate 9 facilitates the downward squeezing of the folding bellows 11, and the air in the folding bellows 11 is compressed downward, and squeezed into the cylinder 12 through the air pipe. As the air is squeezed into the cylinder 12, the movable tube 13 is squeezed outward, and then the squeezing rod 14 is squeezed in the direction away from the cylinder 12 until the side clamps 16 are driven to fit the pipe, and the two sides of the pipe are limited and clamped. Under the elastic action of the squeezing spring 15, the movable plate 9 is facilitated to continue to move downward until the upper pressure plate 10 is driven to press on the top of the pipe, which facilitates the limiting fixation of the pipe.

[0028] A notch is provided on the side of the surface of the processing table 1 away from the fixed frame 2, which cooperates with the arc groove. A support plate is fixed on one side of the bottom of the processing table 1, and a second hydraulic rod 17 is installed on the support plate. A lifting plate 18 is fixed to the telescopic end of the second hydraulic rod 17, and an arc-shaped bending plate 19 is fixed at the top center of the lifting plate 18. Two reinforcing ribs are relatively fixed between the outer wall of the arc-shaped bending plate 19 and the lifting plate 18. Two telescopic rods are connected between the lifting plate 18 and the support frame. The second hydraulic rod 17 facilitates the upward movement of the lifting plate 18, thereby driving the arc-shaped bending plate 19 upward to perform bending operations on the pipes, wherein the telescopic rod ensures the stability of the up and down movement of the arc-shaped bending plate 19.

[0029] A servo motor 20 is installed on one side of the fixed frame 2, and the output shaft of the servo motor 20 is connected to the left end of the screw rod 3. Two limit grooves are opened on the inner side of the fixed frame 2. Limit blocks are fixed on both sides of the movable block 4. The limit blocks and the limit grooves are movably matched. Through the mutual cooperation between the limit blocks and the limit grooves, the movable block 4 is effectively limited and guided, thereby ensuring the stability of the left and right movement of the movable block 4.

[0030] Two T-shaped slots 21 are relatively opened on the processing table 1, and T-shaped blocks 22 are slidingly arranged inside the T-shaped slots 21. The tops of the two T-shaped blocks 22 are respectively connected to the two sides of the bottom of the movable frame 5. The sliding cooperation between the T-shaped blocks 22 and the T-shaped slots 21 further ensures the stability of the left and right movement of the movable frame 5.

[0031] Example:

[0032] When in use, first place the pipe to be bent into the arc groove on the processing table 1, and make one end of the pipe abut against the limit frame 7;

[0033] Then the servo motor 20 is started, and the servo motor 20 drives the screw rod 3 to rotate. Under the thread cooperation between the screw rod 3 and the movable block 4, combined with the mutual cooperation between the limit block and the limit slot, the movable block 4 is driven to move left and right stably. Under the sliding cooperation between the T-shaped block 22 and the T-shaped slot 21, the movable frame 5 is driven to move left and right stably, and then the upper pressure plate 10 and the side clamping plate 16 are driven to move left and right. Under the mutual cooperation between the pointer 24 and the scale 23, the moving distance of the upper pressure plate 10 and the side clamping plate 16 is accurately controlled, which facilitates the limit clamping of different positions of the pipe and achieves the purpose of adjusting the bending position of the pipe.

[0034] After the upper pressure plate 10 and the side clamping plates 16 are adjusted to the appropriate positions, the servo motor 20 stops running and the first hydraulic rod 8 is started. The movable plate 9 is pushed downward by the first hydraulic rod 8. As the movable plate 9 moves downward, the folding bellows 11 on both sides are compressed downward at the same time, so that the air inside the folding bellows 11 is squeezed downward and enters the cylinder 12 through the air pipe, squeezing the movable tube 13 outward. Combined with the squeezing spring 15, the squeezing rod 14 is squeezed in the direction away from the cylinder 12 until the side clamping plates 16 are brought into contact with the surface of the pipe.

[0035] Under the elastic action of the extrusion spring 15, the movable plate 9 continues to move downward until the upper pressure plate 10 presses on the top of the pipe. Combined with the mutual cooperation of the extrusion spring 15 and the side clamping plate 16, the two sides of the pipe are clamped and limited, achieving the purpose of limiting and fixing the pipe and ensuring the stability of the pipe.

[0036] Next, the second hydraulic rod 17 is activated. Under the action of the telescopic rod, the lifting plate 18 is pushed upward, thereby driving the arc-shaped bending plate 19 upward to bend the pipe.

[0037] After the pipe bending is completed, the first hydraulic rod 8 and the second hydraulic rod 17 are adjusted to contract. The contraction of the first hydraulic rod 8 drives the movable plate 9 to move upward, and then drives the upper pressure plate 10 upward away from the top of the pipe. At the same time, the folding bellows 11 is stretched upward, so that the air inside the cylinder 12 is introduced into the stretched folding bellows 11. At this time, the movable tube 13 is driven to move into the cylinder 12, and then the extrusion rod 14 is pulled toward the direction of the cylinder 12 until the side clamp 16 is driven to separate from the side surface of the pipe. At the same time, the arc bending plate 19 is driven downward away from the pipe by the contraction of the second hydraulic rod 17, and then the hydraulic cylinder 6 is started. The hydraulic cylinder 6 is extended to push the limit frame 7 to move to the right, and then the bent pipe is pushed to the right along the direction of the arc groove, and the bent pipe is taken out.

[0038] Compared with the prior art, the present invention adjusts the left and right movement of the movable frame 5 by the mutual cooperation of the servo motor 20, the screw rod 3 and the movable block 4, and adjusts the bending position of the pipe by combining the mutual cooperation of the pointer 24 and the scale 23;

[0039] Then, under the action of the first hydraulic rod 8, the movable plate 9 is pushed downward. As the movable plate 9 moves downward, the folding bellows 11 is compressed, and the air inside the folding bellows 11 is squeezed into the cylinder 12, and the movable tube 13 and the extrusion rod 14 are squeezed outward until the side clamps 16 are clamped on the side surface of the pipe. Combined with the elastic action of the extrusion spring 15, the movable plate 9 continues to move downward, so that the side clamps 16 are tightly pressed against the side of the pipe. At the same time, the upper pressure plate 10 is pressed on the top of the pipe through the movable plate 9. The purpose of limiting and clamping the pipe is achieved, the stability of the pipe during the bending process is ensured, and the problem in the prior art that when the pipe body is placed in the arc groove for limiting, under the elastic action of the spring, the third arc clamping plate first contacts the pipe body, and limits and clamps both sides of the pipe body, which is not convenient for subsequent adjustment of the clamped pipe body to move in the direction of the circular limiting frame, and it is not convenient to adjust the second frame to continue moving according to the bending position, thereby ensuring the limiting effect of the pipe and the smooth progress of the pipe bending operation.

[0040] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. At the same time, the hydraulic cylinder 6, the first hydraulic rod 8, the second hydraulic rod 17 and the servo motor 20 in the present invention are all purchased on the market, and those skilled in the art can install and use them according to the requirements;

[0041] The outer wall of the folding bellows 11 is covered with Oxford cloth, which ensures the expansion and contraction of the folding bellows 11 and the service life of the folding bellows 11.

[0042] All technical features in this embodiment can be freely combined according to actual needs.
