Description

Technical Field

[0001] This utility model relates to a flash shearing fixture for irregularly shaped forged parts, belonging to the field of forging processing fixture technology. Background Technology

[0002] When forming irregularly shaped forged parts, the irregularly shaped forged part 12 has flash 13 on its outer periphery, such as... Figure 4 , Figure 5 As shown. Forging parts with excessively high hardness (HRC38-42) and irregular shapes cannot be directly machined on a lathe. Therefore, shearing fixtures are required for punching.

[0003] The current shearing fixture for punching is described in Chinese Patent Publication No. CN113426916A. Although it can shear the flash of irregularly shaped forged parts, the irregularly shaped forged parts need to be manually reached in and picked up, which reduces the processing efficiency of shearing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tooling for shearing the flash of irregularly shaped forged parts.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a flash shearing fixture for irregularly shaped forged parts, comprising:

[0007] punch;

[0008] A die with a cavity;

[0009] A lower template is fixed below the die, and the lower template has a through hole for the irregular forging part to fall; a pad is installed on the bottom surface of the template for limiting and fitting.

[0010] The top surface of the pad is provided with a sloping, concave sliding opening.

[0011] It also includes the punch located above the die gap.

[0012] The punch is fixedly connected to a pad, and a positioning plate is installed on the outside of the punch to cover it.

[0013] The positioning plate is fixed to the upper template and the pad by screws to form a whole, with the pad located between the upper template and the positioning plate.

[0014] The upper template is equipped with a die handle that provides downward punching force through a step limit. The bottom of the die handle is held in place and fixed inside the upper template by a pad.

[0015] Support plates are fixed at intervals on both sides of the die cavity; a limiting plate is fixedly connected to the top of the die cavity; and the limiting plate is provided with a through hole for the punch to pass through.

[0016] The beneficial effects of this utility model are as follows: after the irregular forging parts and flash are sheared and separated, the irregular forging parts are automatically discharged from the inclined sliding opening of the pad plate without the need for manual insertion to pick them up, which improves the processing efficiency of shearing and solves the problem that irregular forging parts need to be manually inserted to pick them up, resulting in reduced processing efficiency of shearing.

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 3 As shown.

[0025] This application discloses a flash shearing fixture for irregularly shaped forged parts, comprising:

[0026] The die handle 1 provides downward punching force, and the upper template 2 is installed on the die handle 1 by step limiting; it also includes a pad 3 that is fixedly connected to the punch 5 by bolts, and a positioning plate 4 that wraps around the punch 5 is installed on the outside of the punch 5. The positioning plate 4 is fixedly connected to the upper template 2 and the pad 3 as a whole by screws.

[0027] It also includes a die 8 located below the punch 5, with a die hole on the die 8 to accommodate the irregularly shaped forging part 12, and the flash 13 ending at the die hole of the die 8. A lower template 9 is fixed below the die 8 by bolts, and the lower template 9 has a through hole for the irregularly shaped forging part 12 to fall into. A pad 10 is installed on the bottom surface of the template 9 through a slot limit. The top surface of the pad 10 has an inclined and concave sliding opening. After the irregularly shaped forging part 12 and the flash 13 are sheared and separated, the irregularly shaped forging part 12 is automatically discharged from the inclined and concave sliding opening of the pad 10 without the need for manual insertion and retrieval, which improves the shearing efficiency and solves the problem of reduced shearing efficiency due to the need for manual insertion and retrieval of irregularly shaped forging parts.

[0028] Support plates 7 are fixed to both sides of the die cavity 8 at intervals by bolts. A limit plate 6 is fixedly connected to the top of the die cavity 8 by bolts. The bolts connect the limit plate 6, support plates 7, die cavity 8, and lower template 9 to form a whole. The limit plate 6 has a through hole for the punch 5 to pass through. The limit plate 6 is used to contact the positioning plate 4 to limit the stroke.

[0029] The die shank 1, carrying the punch 5, passes through the limiting plate 6 and applies downward pressure to the irregular forging part 12, causing the irregular forging part 12 and the flash 13 to be sheared and separated at the die cavity 8, thereby realizing the processing of the flash 13 on the outer periphery of the irregular forging part 12.
