Technical Field

[0001] The invention relates to the field of automobile parts processing, and in particular to a five-speed shift fork hydraulic bending machine. Background Art

[0003] The existing method of processing the five-speed shift fork is generally through die stamping. After the five-speed shift fork is stamped, it is easy to form an indentation on the surface of the five-speed shift fork, which reduces the aesthetics of the five-speed shift fork and affects the practical performance of the five-speed shift fork. It is easy to break at the indentation position.

[0004] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Summary of the invention

[0006] The above technical objectives of the present invention are achieved by the following technical solutions: A five-speed shift fork hydraulic bending machine, comprising a frame, the frame is provided with a fixing mechanism for fixing the five-speed shift fork, two sets of bending mechanisms for bending the five-speed shift fork, and the two sets of bending mechanisms are respectively arranged on both sides of the fixing mechanism;

[0007] The fixing mechanism comprises a base fixedly connected to the frame, a placement block fixedly connected to the base and on which the five-speed shift fork is placed, a stamping block slidably connected to the frame in the vertical direction and located directly above the placement block, a mounting block arranged on the upper end surface of the stamping block and on which the stamping block is mounted, and a hydraulic cylinder arranged on the frame and driving the mounting block and the stamping block to move up and down, the lower end surface of the stamping block abuts against the upper surface of the five-speed shift fork and clamps and fixes the five-speed shift fork with the placement block, and the corners of the lower end surface of the stamping block are arranged in an arc shape and are provided for the five-speed shift fork to be bent and bonded thereto;

[0008] The bending mechanism includes a rotating frame rotatably connected to the base, a bending block fixedly connected to the rotating frame and abutting against the surface of the five-speed shift fork, a driving assembly arranged on the frame and driving the rotating frame to rotate, and a positioning column fixedly connected to the upper end surface of the bending block and passing through the corresponding mounting hole of the five-speed shift fork. The upper end surface of the bending block is flush with the upper end surface of the placement block, and the bending block abuts against the placement block toward the side wall of the placement block. After the bending block is flipped upward, it drives the five-speed shift fork to bend and makes the five-speed shift fork fit against the side wall of the stamping block. The rotation axis of the bending block is concentrically arranged with the arc-shaped edge corner of the lower end surface of the stamping block.

[0009] The present invention is further configured as follows: the driving assembly includes a connecting shaft fixedly connected to the side wall of the rotating frame and arranged horizontally, a driven gear block fixedly connected to the connecting shaft, a driving motor arranged on the frame, and a driving gear arranged on the output shaft of the driving motor and driving the connecting shaft to rotate, the driving gear is meshed with the driven gear block, the cross-section of the driven gear block is arranged in a sector-shaped circle, and the center distance of the driven gear blocks of the two sets of driving assemblies is smaller than the diameter of the driven gear blocks.

[0010] The present invention is further configured as follows: a limit block is fixedly connected to one end of the bending block away from the placing block to avoid excessive squeezing of the five-speed shift fork; the limit block protrudes from the upper end surface of the bending block and can abut against the side wall of the stamping block.

[0011] The present invention is further configured as follows: contact sensors for detecting the position of the five-speed shift fork after bending are arranged on both symmetrical side walls of the stamping block, and the five-speed shift fork contacts the contact sensors after bending 90°.

[0012] The present invention is further configured as follows: both symmetrical side walls of the placement block are provided with anti-floating blocks for the side walls of the bending block to abut against, and the anti-floating blocks are bolted to the placement block.

[0013] The present invention is further configured as follows: the frame is provided with guide posts for keeping the mounting block from sliding up and down, and the guide posts are vertically arranged.

[0014] In summary, the present invention has the following beneficial effects:

[0015] When clamping and fixing the five-speed shift fork, first place the five-speed shift fork on the placement block, and then use the hydraulic cylinder to move the mounting block and the punching block downward so that the lower end surface of the punching block abuts against the five-speed shift fork to clamp and fix the five-speed shift fork;

[0016] The driven gear block has a sector angle of 90°, which ensures that the device can operate normally when the center distance between the two sector driven gear blocks is smaller than the diameter of the driven gear block, thereby reducing the volume of the entire device and making the device more compact. At the same time, when the five-speed shift fork is bent, after the fixing mechanism fixes the five-speed shift fork, the upper surface of the bending block is flush with the upper surface of the placement block, and the positioning column is inserted into the corresponding mounting hole of the five-speed shift fork. Then, the driving motor drives the rotating frame and the bending block to rotate, and the bending block abuts against the lower surface of the five-speed shift fork and drives the corresponding part to bend upward and makes the five-speed shift fork abut against the side wall of the stamping block after being bent. Moreover, since the rotation axis of the bending block is concentric with the arc-shaped corner of the lower end face of the stamping block, it is ensured that the bending part of the five-speed shift fork fits the side wall and the arc-shaped corner of the lower end face of the stamping block.

[0017] When the five-speed shift fork is bent and fits against the side wall of the stamping block, the five-speed shift fork first abuts against the contact sensor located on the side wall of the stamping block, and sends a corresponding control signal through the contact sensor, and the drive motor is controlled to stop rotating through the control circuit, and the limit block abuts against the side wall of the stamping block to further prevent the bending block from continuing to rotate toward the stamping block, thereby improving the safety performance of the present application;

[0018] When the bending block abuts against the anti-floating block, ensure that the upper surface of the bending block is set horizontally, so as to achieve the positioning effect of the bending block. At the same time, the bending block first contacts the anti-floating block to play an anti-floating buffering role. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0026] like Figures 1 to 4 As shown, a five-speed shift fork hydraulic bending machine proposed by the present invention comprises a frame 1, the frame 1 is provided with a fixing mechanism for fixing the five-speed shift fork, and two sets of bending mechanisms for bending the five-speed shift fork, and the two sets of bending mechanisms are respectively arranged on both sides of the fixing mechanism;

[0027] The fixing mechanism includes a base 2 fixedly connected to the frame 1, a placement block 3 fixedly connected to the base 2 and for placing the five-speed fork, a mounting block 5 slidably connected to the frame 1 in the vertical direction and located directly above the placement block 3, a stamping block 4 arranged on the lower end face of the mounting block 5, and a hydraulic cylinder (not shown in the figure) arranged on the frame 1 and driving the mounting block 5 and the stamping block 4 to move up and down. The lower end face of the stamping block 4 abuts against the upper surface of the five-speed fork and clamps and fixes the five-speed fork with the placement block 3. The corners of the lower end face of the stamping block 4 are arranged in an arc shape and are bent and fitted to the five-speed fork. When clamping and fixing the five-speed fork, first place the five-speed fork on the placement block 3, and then move the mounting block 5 and the stamping block 4 downward through the hydraulic cylinder so that the lower end face of the stamping block 4 abuts against the five-speed fork and clamps and fixes the five-speed fork.

[0028] The bending mechanism includes a rotating frame 6 rotatably connected to the base 2, a bending block 7 fixedly connected to the rotating frame 6 and abutting against the surface of the five-speed fork, a driving assembly arranged on the frame 1 and driving the rotating frame 6 to rotate, and a positioning column 8 fixedly connected to the upper end surface of the bending block 7 and penetrating the corresponding mounting hole 17 of the five-speed fork. The rotating frame 6 is arranged in a U shape, and the rotating axis of the rotating frame 6 is arranged horizontally, the upper end surface of the bending block 7 can be flush with the upper end surface of the placement block 3, and the bending block 7 abuts against the placement block 3 toward the side wall of the placement block 3, and the bending block 7 turns upward to drive the five-speed fork to bend and make the five-speed fork fit the side wall of the stamping block 4, and the rotation axis of the bending block 7 is arranged concentrically with the arc-shaped corner of the lower end surface of the stamping block 4. The driving assembly includes a connecting shaft 9 fixedly connected to the side wall of the rotating frame 6 and arranged horizontally, a driven gear block 10 fixedly connected to the connecting shaft 9, a driving motor 11 arranged on the frame 1, and a driving gear 12 arranged on the output shaft of the driving motor 11 and driving the connecting shaft 9 to rotate. The driving gear 12 is meshed with the driven gear block 10. The cross-section of the driven gear block 10 is arranged in a sector-shaped circle. The sector angle of the driven gear block 10 is 90°, and the center distance of the driven gear blocks 10 of the two sets of driving assemblies is less than the diameter of the driven gear block 10. By making the sector angle of the driven gear block 10 90°, it is ensured that when the center distance between the two sector driven gear blocks 10 is less than the diameter of the driven gear block 10, it can operate normally, thereby reducing the volume of the entire device and making the device more compact; at the same time, when the five-speed shift fork is bent, after the fixing mechanism fixes the five-speed shift fork, the upper surface of the bending block 7 is flush with the upper surface of the placement block 3, and the positioning column 8 is penetrated into the corresponding mounting hole 17 of the five-speed shift fork, and then the driving motor 11 drives the rotating frame 6 and the bending block 7 to rotate, the bending block 7 abuts against the lower surface of the five-speed shift fork and drives the corresponding part to bend upward and make the five-speed shift fork abut against the side wall of the stamping block 4 after bending, and because the rotation axis of the bending block 7 is concentric with the arc-shaped corner of the lower end face of the stamping block 4, it is ensured that the bending part of the five-speed shift fork fits the side wall and the arc-shaped corner of the lower end face of the stamping block 4.

[0029] The end of the connection block away from the placement block 3 is fixedly connected with a limit block 13 to avoid excessive squeezing of the five-speed shift fork. The limit block 13 protrudes from the upper end surface of the bending block 7 and can abut against the side wall of the stamping block 4; and the two symmetrical side walls of the stamping block 4 are both installed with contact sensors 14 for detecting the position of the five-speed shift fork after bending. The contact sensor 14 is electrically connected to the control circuit of the present application (the control circuit is a prior art and is not described here). The five-speed shift fork contacts the contact sensor 14 after bending 90°. When the five-speed shift fork is bent and attached to the side wall of the stamping block 4, the five-speed shift fork first abuts against the contact sensor 14 located on the side wall of the stamping block 4, and a corresponding control signal is sent through the contact sensor 14. The control circuit controls the drive motor 11 to stop rotating, and the limit block 13 abuts against the side wall of the stamping block 4 to further prevent the bending block 7 from continuing to rotate toward the stamping block 4, thereby improving the safety performance of the present application.

[0030] The two symmetrical side walls of the placement block 3 are both provided with anti-floating blocks 15 for the side walls of the bending block 7 to abut against, and the anti-floating blocks 15 are bolted to the placement block 3. When the bending block 7 abuts against the anti-floating blocks 15, it is ensured that the upper surface of the bending block 7 is arranged horizontally, so as to achieve the positioning effect of the bending block 7, and at the same time, the bending block 7 first contacts the anti-floating blocks 15 to play an anti-floating buffering effect.

[0031] In order to ensure that the mounting block 5 slides in the vertical direction, the frame 1 is provided with a guide column 16 for keeping the mounting block 5 sliding up and down, and the guide column 16 is arranged vertically.
