Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an automotive gear stamping die with an ejection mechanism. Background Technology

[0002] Automotive gears are one of the main components of the automotive transmission system, used to realize the power transmission of the automotive drive system. They can convert the speed and torque generated by the engine into the rotational power of the tires, thereby driving the car. In order to realize the stamping process of automotive gears, automotive gear stamping dies are required.

[0003] Currently, in the stamping process of automotive gears, the general method is to place the metal sheet to be processed on the lower die, and then use a drive structure such as an electric push rod to move the upper die downward until it is completely aligned with the lower die. Under the action of a mechanical stamping press, the metal sheet is stamped into the shape of a gear. However, after the gear is formed, it may be affected by the internal stamping stress, causing the gear to stick to the lower die, making it difficult to remove the gear. Therefore, there is an urgent need for an automotive gear stamping die with an ejection mechanism to solve the above problems. Utility Model Content

[0030] like Figures 1 to 6As shown in the figure, this embodiment provides an automotive gear stamping die with an ejection mechanism. This automotive gear stamping die with an ejection mechanism includes a lower die 1, an upper die 2 on the top of the lower die 1, and punches 3 evenly distributed on the bottom of the upper die 2. The lower die 1 has a processing groove 5 corresponding to the punches 3 inside. The lower die 1 and the upper die 2 are connected by electric push rods 4. The electric push rods 4 are arranged in pairs and correspondingly. The output end of the electric push rod 4 is fixedly connected to the upper die 2. The bottom of the electric push rod 4 is fixedly connected to the lower die 1 through a plate.

[0031] A table 6 is movably installed inside the processing groove 5. A limiting groove 7 is opened inside the lower mold 1. The limiting groove 7 is connected to the inside of the processing groove 5 and the two have the same diameter. A lifting block 8 is installed at the bottom of the table 6. The lifting block 8 is located in the limiting groove 7. An inclined groove 9 is opened inside the lifting block 8. The limiting groove 7 has the same diameter as the inside of the processing groove 5, which can limit the table 6 and prevent it from shifting.

[0032] The lower mold 1 is equipped with a bidirectional hydraulic cylinder 10. The bidirectional hydraulic cylinder 10 is located at the bottom of the lower mold 1. The output end of the bidirectional hydraulic cylinder 10 is equipped with a positioning shaft 11. Both ends of the positioning shaft 11 are movably connected to rollers 12. The rollers 12 are in pairs and correspond to each other. The rollers 12 are located on one side of the lifting block 8 and inside the inclined groove 9, which can facilitate pushing the lifting block 8 to rise, so as to achieve the purpose of ejecting the gear. At the same time, when the rollers 12 move, they are located on one side of the inclined groove 9, which can provide some support force for the lifting block 8.

[0033] A connecting block 13 is installed on the positioning shaft 11. The connecting block 13 is located between the two sets of rollers 12. The end of the connecting block 13 away from the positioning shaft 11 is fixedly connected to the output end of the bidirectional hydraulic cylinder 10. The setting of the connecting block 13 facilitates the driving of the positioning shaft 11.

[0034] The bottom of the connecting block 13 is fixedly connected to a T-shaped strip 14. The T-shaped strip 14 has two sets of corresponding parts. The lower mold 1 has a T-shaped groove 15 that matches the T-shaped strip 14, which makes the connecting block 13 move more stably and avoids the positioning shaft 11 from shifting.

[0035] A fixing sleeve 16 is fixedly connected to the bidirectional hydraulic cylinder 10. There are two sets of fixing sleeves 16, which correspond to each other. The bottom of the two sets of fixing sleeves 16 is fixedly connected to a base plate 17. The base plate 17 is fixed in the lower mold 1 by screws, which can fix the bidirectional hydraulic cylinder 10.

[0036] A connecting column 18 is fixedly connected between the platform 6 and the lifting block 8. The platform 6 and the lifting block 8 are fixedly connected through the connecting column 18, which facilitates the lifting operation of the platform 6.

[0037] A motor 19 is fixedly connected to one side of the lower mold 1, and a lead screw 20 is fixedly connected to the output end of the motor 19. A guide rod 21 is provided on the other side of the lower mold 1. Sliders 22 are installed on the outer surfaces of both the lead screw 20 and the guide rod 21. One set of sliders 22 is threadedly connected to the lead screw 20, and the other set of sliders 22 is slidably connected to the guide rod 21. The guide rod 21 can make the sliders 22 more stable during movement, and the lead screw 20 can easily drive the movement of the sliders 22.

[0038] Both sides of the lower mold 1 are fixedly connected to fixing blocks 27. The fixing blocks 27 are in pairs and correspond to each other. The lead screw 20 and the guide rod 21 are located between the two sets of fixing blocks 27. The lead screw 20 is rotatably connected to the fixing blocks 27, and the guide rod 21 is fixedly connected to the fixing blocks 27. The output end of the motor 19 extends to the inside of the fixing block 27 and is fixedly connected to the lead screw 20. The motor 19 is fixedly connected to the lower mold 1 through the mounting base.

[0039] The top of the lower mold 1 is provided with a feeding plate 24. Limiting plates 25 are fixedly connected to both sides of the top of the lower mold 1. The feeding plate 24 is located between the two sets of limiting plates 25. Connecting strips 23 are fixedly connected to both ends of the feeding plate 24. Guide grooves 26 are opened inside the limiting plates 25. The end of the connecting strip 23 away from the feeding plate 24 extends through the guide groove 26 to the outside of the limiting plate 25 and is fixedly connected to the slider 22. The feeding plate 24 can concentrate the ejected gears for feeding, so as to improve work efficiency. At the same time, the limiting plates 25 can prevent the gears from slipping outside the lower mold 1.

[0040] The lower mold 1 has a feeding tray 28 on both sides. The two ends of the limiting plate 25 are fixedly connected to the two feeding trays 28 respectively, so that the formed gear can be collected.

[0041] When in use, the metal sheet is placed in the processing groove 5, and then the upper mold 2 is moved towards the lower mold 1 by the electric push rod 4 until the punch 3 is located in the processing groove 5. After the stamping operation is completed, the upper mold 2 is raised by the electric push rod 4.

[0042] Then, the bidirectional hydraulic cylinder 10 can be activated to push the connecting block 13 to move the positioning shaft 11 into the inclined groove 9, and the roller 12 moves along the inclined groove 9 along with the positioning shaft 11, so that the lifting block 8 slowly rises. During this process, the lifting block 8 applies a pushing force to the table 6 through the connecting column 18, so that the table 6 rises along the processing groove 5, which can make the table 6 rise more stably until the table 6 and the surface of the lower mold 1 are on the same horizontal plane, thus completing the ejection purpose and facilitating the removal of the gear.

[0043] Then, by starting the motor 19, the lead screw 20 is rotated, causing the slider 22 to move with the rotation of the lead screw 20. The connecting bar 23 drives the unloading plate 24 to move, and at the same time, the connecting bar 23 moves along the guide groove 26, causing the unloading plate 24 to move horizontally along the surface of the lower mold 1, so as to push the ejected gear into the unloading tray 28. This reduces the workload of the workers and thus improves work efficiency.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
