Description

Technical Field

[0001] This utility model belongs to the technical field of gear manufacturing, and in particular relates to a gear rapid forging die. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, the principle of gear cutting and the subsequent emergence of specialized machine tools and cutting tools based on this principle were developed. With the development of production, the smoothness of gear operation has become important. Gear production generally uses forging with molds, resulting in gears with extremely high hardness and better wear resistance. A search revealed a patent application with application number 202122632938.3, which discloses a hot forging mold for gear production, including a mold base, insertion hole, cavity, pressure mold, mounting post, insert rod, and cleaning device. This design incorporates a cleaning device inside the pressure mold. After the pressure mold is raised, the spring loses force, causing the shovel plate to reset. The reset shovel plate cleans the bottom of the pressure mold, achieving the purpose of cleaning the pressure mold.

[0003] However, in actual use, the applicant found that during the gear forging production process, due to the lack of material removal structure on the mold, the forged gear was inside the cavity and it was not convenient for personnel to quickly remove it, thus reducing the forging production efficiency of gears. In view of this, we propose a gear rapid forging mold. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a gear rapid forging die, comprising a die base and a pressing die. The top of the die base has a die cavity, and a rectangular frame is slidably connected to the die base below the die cavity. A push rod is symmetrically and vertically fixed at the bottom of the rectangular frame, and a circular plate is fixedly installed at the upper end of the push rod. A rotating shaft is rotatably connected to the inside of the die base via a bearing. A cam is sleeved and fixed on the rotating shaft, and the cam is located in the rectangular frame. The front end of the rotating shaft extends to the outside of the die base and is fixedly provided with a rotating handle. A connecting slide is slidably connected to the outer wall of the die base, and a material shielding hopper is fixedly connected to the tail end of the connecting slide. A mounting column is fixedly connected to the top of the pressing die, and the pressing die is positioned directly above the die base.

[0006] Preferably, guide sliders are symmetrically arranged on both sides inside the connecting slide, and the guide sliders slide along the guide grooves opened on both sides of the mold base.

[0007] Preferably, the two ends of the connecting carriage are fixedly connected to the two sides of the material shielding hopper, respectively.

[0008] Preferably, the bottom of the material hopper is higher than the top of the mold base, and a handle is fixedly provided on the front side of the connecting slide.

[0009] Preferably, insertion holes are provided at the four corners of the top of the mold base, and insertion rods are provided at the four corners of the bottom of the mold, with the insertion rods cooperating with the insertion holes.

[0010] Preferably, the top of the circular plate is flush with the bottom of the mold cavity, and the bottom of the mold cavity is provided with a clearance groove for avoiding the circular plate.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a gear rapid forging die. By turning the dial clockwise, the rotating shaft rotates along with the cam. The cam drives the rectangular frame and the ejector rod to move upwards, thereby ejecting the gear segment formed inside the die cavity through the circular plate. This facilitates the removal of the gear and improves the efficiency of the gear die segment. By pulling the connecting slide forward, the material shielding hopper moves to the top of the die base. When the bottom of the die is cleared using the shovel plate, the material shielding hopper blocks the die cavity, preventing the cleared material from falling into the die cavity and reducing the forging quality of the gear.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A gear rapid forging die includes a die base 1 and a pressure die 2. A die cavity 11 is formed at the top of the die base 1. A rectangular frame 6 is slidably connected to the die base 1 below the die cavity 11. Ejector rods 7 are symmetrically and vertically fixed at the bottom of the rectangular frame 6. A circular plate 71 is fixedly mounted at the upper end of the ejector rod 7. The top of the circular plate 71 is flush with the bottom of the die cavity 11. A clearance groove for the circular plate 71 is formed at the bottom of the die cavity 11. A rotating shaft 8 is rotatably connected to the inside of the die base 1 via a bearing. A cam 9 is sleeved and fixed on the rotating shaft 8, and the cam 9 is located within the rectangular frame 6. The front end of the rotating shaft 8 extends to the outside of the die base 1 and is fixedly mounted with a handle 81. By turning the handle 81 clockwise, the rotating shaft 8 rotates, causing the cam 9 to rotate as well. The cam 9 drives the rectangular frame 6 and ejector rods 7 to move upwards, thereby ejecting the gear segment formed inside the die cavity 11 through the circular plate 71. The gear can be removed by personnel, thereby improving the efficiency of the gear mold segment. The four corner positions of the top of the mold base 1 are provided with insertion holes 12. The top of the pressure mold 2 is fixedly connected with the mounting column 3, and the pressure mold 2 is set directly above the mold base 1. The four corner positions of the bottom of the pressure mold 2 are provided with insertion rods 21, which are connected to the insertion holes 12. When processing the gear mold segment, the blank can be placed in the mold cavity 11, and then the pressure mold 2 is driven to move downward to forge the blank, so that the blank is formed inside the mold cavity 11. After the gear is formed, the personnel can manually turn the handle 81 clockwise to drive the rotating shaft 8 to rotate together with the cam 9. The cam 9 can drive the rectangular frame 6 and the push rod 7 to move upward together, so that the gear formed inside the mold cavity 11 can be pushed out by the circular plate 71, making it easy for personnel to remove the formed gear from the inside of the mold cavity 11.

[0022] A connecting slide 4 is slidably connected to the outer wall of the mold base 1. Guide sliders 41 are symmetrically arranged on both sides inside the connecting slide 4. The guide sliders 41 slide along guide grooves opened on both sides of the mold base 1. A material-blocking hopper 5 is fixedly connected to the tail end of the connecting slide 4. Both ends of the connecting slide 4 are fixedly connected to the sides of the material-blocking hopper 5, respectively. The bottom of the material-blocking hopper 5 is higher than the top of the mold base 1. A handle 42 is fixedly installed on the front side of the connecting slide 4. By pulling the connecting slide 4 forward, the material-blocking hopper 5 is moved to directly above the mold base 1. This allows for material removal from the bottom of the mold 2 using a shovel. The material shielding hopper 5 shields the mold cavity 11 to prevent the cleaned material from falling into the mold cavity 11 and reducing the forging quality of the gear. When it is necessary to clean the material at the bottom of the die 2 after the gear forging is completed, you can first hold the handle 42 and pull the connecting slide 4 forward. The connecting slide 4 will drive the material shielding hopper 5 forward, so that the material shielding hopper 5 is moved directly above the die base 1. This will prevent the material from falling into the mold cavity 11 and reducing the forging quality of the gear when cleaning the bottom of the die 2. After cleaning, push the connecting slide 4 backward to reset the material shielding hopper 5.

[0023] Working principle: During use, when processing the gear mold segment, the blank can be placed in the mold cavity 11, and then the pressure mold 2 is driven to move downward to forge the blank, so that the blank is formed inside the mold cavity 11. After the gear is formed, the operator can manually turn the handle 81 clockwise to drive the rotating shaft 8 to rotate together with the cam 9. The cam 9 can drive the rectangular frame 6 and the ejector rod 7 to move upward together, so that the gear formed inside the mold cavity 11 can be ejected by the circular plate 71, making it easy for the operator to take the formed gear out of the mold cavity 11. After the gear forging is completed, when it is necessary to clean the material at the bottom of the pressure mold 2, the operator can first hold the handle 42 and pull the connecting slide 4 forward. The connecting slide 4 drives the material blocking hopper 5 to move forward, so that the material blocking hopper 5 moves directly above the mold base 1. This can prevent the material from falling into the mold cavity 11 and reducing the forging quality of the gear when cleaning the bottom of the pressure mold 2. After cleaning, push the connecting slide 4 backward to reset the material blocking hopper 5.
