Description

Technical Field

[0001] This invention relates to gear forging technology, and more specifically to a high-precision transmission gear forging device. Background Technology

[0002] In modern industrial production, transmission gears are key components in mechanical transmission systems, and their precision and quality directly affect the operating performance and reliability of mechanical equipment. Forging, as one of the important processes in producing transmission gears, not only effectively improves the strength and toughness of gears and reduces or eliminates internal defects, but also improves the wear resistance and impact resistance of gears, resulting in better gear quality.

[0003] During the forging process of gears, a red-hot cylindrical workpiece is placed under a forging hammer and continuously hammered to shape it. In order to ensure the uniformity of the forging process and prevent excessive local deformation, the operator needs to continuously rotate the workpiece with clamps. For some larger gears, the operator needs to expend more effort, which makes the labor intensity of the operator high. As a result, the work efficiency may decrease during long working hours. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision transmission gear forging device to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision transmission gear forging device, comprising a machine body, a forging hammer disposed on the machine body, and an anvil block, wherein a columnar forging is placed on the anvil block; The top surface of the anvil block is provided with an arc-shaped guide frame, and an arc-shaped guide bar is slidably connected to the inner side of the arc-shaped guide frame. A receiving block is symmetrically installed on both sides of the top of the arc-shaped guide bar. An extension rod is slidably connected to the inner side of the receiving block. A clamping plate is provided at the end of the extension rod near the columnar forging, and a drive rod is connected to the end of the extension rod away from the columnar forging. An electric telescopic rod is installed on the top of the receiving block, and the telescopic end of the electric telescopic rod is fixedly connected to the drive rod. A drive unit is provided on the outside of the arc-shaped guide bar, and the drive unit drives the arc-shaped guide bar to reciprocate within a fixed angle range along the inner wall of the arc-shaped guide frame.

[0006] Furthermore, the position of the clamping plate corresponds to that of the columnar forging, and the side of the clamping plate closest to the columnar forging is roughened.

[0007] Furthermore, the drive unit includes drive teeth disposed on the side of the arc-shaped guide bar, a support platform is mounted on the side of the anvil block, a gear is rotatably connected to the support platform, the gear meshes with the drive teeth, a drive motor is mounted on the machine body, and transmission wheels are mounted on the output shaft of the drive motor and on the outside of the gear, and a transmission belt is connected between the two transmission wheels.

[0008] Furthermore, a conductive cavity is provided on the inner side of the receiving block, the extension rod is slidably connected to the inner side of the conductive cavity, a monitoring block is slidably connected to the inner side of the conductive cavity, a pressure spring is fixedly installed between the monitoring block and the extension rod, the driving rod is slidably connected to the inner side of the conductive cavity, and the driving rod is fixedly connected to the monitoring block.

[0009] Furthermore, the monitoring block includes a carrier block, on which a connecting groove is formed. The connecting groove is vertically arranged, and a pressure-bearing block is slidably connected to the inner side of the connecting groove. The pressure-bearing block is spaced apart from the inner wall of the connecting groove. A pressure sensor is provided on the inner wall of the connecting groove. When the carrier block moves and drives the pressure-bearing block to move to compress the pressure spring, the pressure-bearing block abuts against the pressure sensor and transmits the pressure to the pressure sensor.

[0010] Furthermore, a controller is installed on the machine body, and the pressure sensor, electric telescopic rod, and drive motor are all electrically connected to the controller.

[0011] Furthermore, a connecting block is installed at the end of the extension rod near the clamping plate. An embedded groove is provided on the top of the connecting block.

Corresponding threaded grooves are provided on the surface of the cover plate and the surface of the connecting block. A locking screw is threadedly connected to the inner side of the threaded groove.

[0012] Furthermore, the shape and size of the recessed groove are adapted to the recessed panel.

[0013] Compared with the prior art, the high-precision transmission gear forging device provided by the present invention has the following advantages: 1. In the operation of this high-precision transmission gear forging device, after one hammer blow, the electric telescopic rod drives the clamping plates on both sides to hold the columnar forging on the surface. This causes the drive unit to drive the clamping plates to rotate the columnar forging at a fixed angle. After the columnar forging rotates, the clamping plates move in the opposite direction to reset. After the next hammer blow, the columnar forging is driven to rotate at a fixed angle again. This allows the columnar forging to be hammered and shaped more effectively during the gear forging process.

[0014] 2. This high-precision transmission gear forging device, through the cooperation between the connecting block, the inner groove, the inner plate and the cover plate, allows the clamping plate to be disassembled as needed, so that it can be easily replaced or maintained in case of subsequent damage or failure.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1: Please see Figures 1-5 A high-precision transmission gear forging device includes a machine body 1, a forging hammer 101 disposed on the machine body 1, and an anvil block 102, on which a columnar forging is placed; An arc-shaped guide frame 2 is provided on the top surface of the anvil block 102. An arc-shaped guide bar 21 is slidably connected to the inner side of the arc-shaped guide frame 2. A receiving block 22 is symmetrically installed on both sides of the top of the arc-shaped guide bar 21. An extension rod 23 is slidably connected to the inner side of the receiving block 22. A clamping plate 24 is provided at the end of the extension rod 23 near the columnar forging. A drive rod 25 is connected to the end of the extension rod 23 away from the columnar forging. An electric telescopic rod 26 is installed on the top of the receiving block 22. The telescopic end of the electric telescopic rod 26 is fixedly connected to the drive rod 25. A drive unit is provided on the outside of the arc-shaped guide bar 21. The drive unit drives the arc-shaped guide bar 21 to reciprocate within a fixed angle range along the inner wall of the arc-shaped guide frame 2.

[0020] It should be noted that the position of the clamping plate 24 corresponds to the columnar forging, and the side of the clamping plate 24 closest to the columnar forging is roughened, which makes the clamping stability of the clamping plate 24 better when clamping the columnar forging.

[0021] In this embodiment, the drive unit includes drive teeth 3 disposed on the side of the arc-shaped guide bar 21, a support platform is mounted on the side of the anvil block 102, a gear 31 is rotatably connected on the support platform, the gear 31 meshes with the drive teeth 3, a drive motor 32 is mounted on the body 1, and transmission wheels 33 are mounted on the output shaft of the drive motor 32 and on the outside of the gear 31, and a transmission belt 34 is connected between the two transmission wheels 33.

[0022] During operation, the operator places the red-hot cylindrical forging on the anvil 102 and then hammers it with the forging hammer 101. During each hammering, after one strike, the two sets of electric telescopic rods 26 retract and move the side clamps 24 to contact and clamp the sides of the cylindrical forging. Then, the drive motor 32 drives the gear 31 to rotate, allowing the arc-shaped guide bar 21 to slide along the inner wall of the arc-shaped guide frame 2 under the engagement of the drive teeth 3. Furthermore, as the arc-shaped guide bar 21 moves, it drives the receiving block 22 to move synchronously, thereby enabling... The clamping plate 24 can drive the columnar forging to rotate at a fixed angle. After rotation, the telescopic end of the electric telescopic rod 26 extends and drives the clamping plate 24 to move and separate from the columnar forging. At the same time, the drive motor 32 drives the gear 31 to rotate in the opposite direction, causing the arc-shaped guide bar 21 to rotate in the opposite direction and drive the clamping plate 24 to reset. When the columnar forging is hammered again, the clamping plate 24 repeats the previous action and drives the columnar forging to rotate again, thereby making the columnar forging more uniform during the hammering process and eliminating the need for manual auxiliary rotation, thus significantly improving the forging efficiency of the gear.

[0023] Example 2: Please see Figures 3-5This embodiment provides a technical solution based on the above embodiments: a conductive cavity is provided on the inner side of the receiving block 22, the extension rod 23 is slidably connected to the inner side of the conductive cavity, a monitoring block 4 is slidably connected to the inner side of the conductive cavity, a pressure spring 41 is fixedly installed between the monitoring block 4 and the extension rod 23, the driving rod 25 is slidably connected to the inner side of the conductive cavity, and the driving rod 25 is fixedly connected to the monitoring block 4.

[0024] It should be added that the monitoring block 4 includes a carrier block 401, on which a connecting groove 402 is provided. The connecting groove 402 is vertically arranged, and a pressure-bearing block 403 is slidably connected to the inner side of the connecting groove 402. The pressure-bearing block 403 is spaced apart from the inner wall of the connecting groove 402. A pressure sensor 404 is provided on the inner wall of the connecting groove 402. When the carrier block 401 moves and drives the pressure-bearing block 403 to move to compress the pressure spring 41, the pressure-bearing block 403 abuts against the pressure sensor 404 and transmits the pressure to the pressure sensor 404.

[0025] Furthermore, a controller is installed on the machine body 1, and the pressure sensor 404, electric telescopic rod 26, and drive motor 32 are all electrically connected to the controller.

[0026] Furthermore, the pressure sensor 404 is used to detect the clamping pressure of the clamping plate 24 during operation, and the magnitude of the clamping force can be preset by the controller.

[0027] During operation, the electric telescopic rod 26 drives the drive rod 25 to move, which in turn pushes the monitoring block 4 to move. The movement of the monitoring block 4 then pushes the pressure spring 41 to move, causing the extension rod 23 and the clamping plate 24 to move closer to the columnar forging and contact its side. Once the clamping plate 24 contacts the columnar surface, it stops moving. When the monitoring block 4 continues to move, it compresses the pressure spring 41, causing the contact pressure between the clamping plate 24 and the surface of the columnar forging to gradually increase. At this time, with the cooperation of the pressure block 403, the pressure sensor 404 detects the clamping pressure between the clamping plate 24 and the columnar forging and transmits it to the controller. When the clamping pressure reaches the set range, the controller controls the electric telescopic rod 26 to stop working and controls the drive motor 32 to drive the gear 31 to rotate, causing the clamping plate 24 to drive the columnar forging to rotate synchronously. Example 3: Please see Figure 6 This embodiment provides a technical solution based on the above embodiments: a connecting block 5 is installed at the end of the extension rod 23 near the clamping plate 24, an embedded groove 51 is provided on the top of the connecting block 5, an embedded plate 52 is provided on the surface of the clamping plate 24, a cover plate 53 adapted to the embedded groove 51 is provided on the top of the connecting block 5, and corresponding threaded grooves 54 are provided on the surface of the cover plate 53 and the surface of the connecting block 5, and a locking screw 55 is threadedly connected to the inner side of the threaded groove 54.

[0028] It should be noted that the shape and size of the recessed groove 51 are compatible with the recessed panel 52.

[0029] When the clamping plate 24 is damaged and needs to be removed for replacement or repair, the operator removes the locking screw 55 so that the cover plate 53 can be separated from the connecting block 5. At this time, the operator moves the clamping plate 24 upward so that the inner plate 52 is removed from the inner groove 51, thereby removing the clamping plate 24. When the clamp plate 24 needs to be installed, the inner plate 52 on the clamp plate 24 is directly inserted into the inner groove 51, and then the cover plate 53 is connected to the connecting block 5 by the locking screw 55, thereby completing the installation of the clamp plate 24.

[0030] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
