Description

Technical Field

[0001] This utility model relates to the field of punching and forging technology, specifically a novel short-process punching and forging device. Background Technology

[0002] Punching forging is commonly used in the production of ring forgings. Traditional punching forging generally requires a moving worktable and is carried out by three stations to complete upsetting, punching, and punching the connecting skin. However, the punching and forging process at the three stations of the moving worktable takes a long time. After most of the billets are punched and forged, the temperature drops significantly, resulting in high rolling resistance in the next ring rolling process. The billet output has a draft angle, which leads to serious material waste as a ring forging. As a rolled billet, the billet has an irregular shape, which is not conducive to the forming of the next rolling process. Summary of the Invention

[0003] The purpose of this invention is to provide a novel short-process punching and forging apparatus to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel short-process punching and forging device includes a processing table, a lower upsetting table at the center of the upper surface of the processing table, a side plate on the rear end face of the processing table, an upper upsetting table between the top of the side plate and the processing table above the lower upsetting table, a support frame on the upper surface of the upper upsetting table, and a third hydraulic cylinder on the top of the support frame. An installation groove is provided on the right side of the processing table. A first hydraulic cylinder is provided in the installation groove below the lower upsetting table. A lower punch is provided at the end of the telescopic arm of the first hydraulic cylinder. The lower punch moves up and down to complete the lower punching action. An mounting base is provided on the upper surface of the upsetting platform. A second hydraulic cylinder is provided above the mounting base. An upper punch is provided at the end of the telescopic arm of the second hydraulic cylinder. The upper punch moves up and down to complete the upper punching action.

[0005] Furthermore, the side plate is L-shaped, and the side plate is fixed to the processing table by bolts. The third hydraulic cylinder is fixed to the side plate by screws, and the telescopic arm of the third hydraulic cylinder is slidably engaged with the side plate.

[0006] In this utility model, the side plate provides a force point for the installation of the third hydraulic cylinder, and the control switch on the outer wall of the third hydraulic cylinder controls the extension or retraction of the telescopic arm to adjust the distance between the upper and lower upsetting platforms, so as to ensure a tight fit between the punched forgings after different processes.

[0007] Specifically, the bottom of the support frame is fixed to the top of the upper upsetting table by bolts, the bottom of the telescopic arm of the third hydraulic cylinder is fixed to the top of the support frame by bolts, the rear end face of the support frame is symmetrically provided with a limiting rod, and the front end face of the side plate is provided with a sliding groove corresponding to the limiting rod.

[0008] In this invention, the limiting rod and the sliding groove are connected to each other to achieve the stability of the support frame's up and down movement and reduce the impact of the support frame's rotational offset direction on the punching and forging process.

[0009] It should be noted that the upper upsetting platform has an upper through hole in the middle, the upper punch is slidably inserted into the upper through hole, and the outer diameter of the upper upsetting platform is adapted to the outer diameter of the lower upsetting platform.

[0010] In this invention, the upper punch passes through the upper hole and contacts the bottom of the forging to punch a hole at the bottom. The upper upsetting platform corresponds to the lower upsetting platform, which stably clamps and holds the forging that needs to be punched.

[0011] It is worth adding that the bottom of the lower upsetting table is fixed to the top of the processing table by bolts, and a connecting groove is opened in the middle of the upper surface of the lower upsetting table. A lower through hole is opened at the bottom of the connecting groove, and the inner diameter of the lower through hole is adapted to the outer diameter of the lower punch.

[0012] In this invention, the connecting groove facilitates the collection and matching of the punched skin when the upper and lower punches descend synchronously, reducing the impact of the punched skin on the object.

[0013] Furthermore, the first hydraulic cylinder is fixedly connected to the processing table by bolts, and the end of the telescopic arm of the first hydraulic cylinder is fixedly connected to the lower punch by screws.

[0014] In this invention, the control switch on the outer wall of the first hydraulic cylinder controls the extension or retraction of the telescopic arm, enabling the lower punch to move up and down in the lower hole, which helps the lower punch to fit the bottom hole of the forging.

[0015] In addition, the outer diameter of the lower punch is adapted to the outer diameter of the upper punch.

[0016] In this invention, the lower punch and the upper punch are matched in a corresponding manner, which helps to unify the punching diameter of the punched forgings.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a lower upsetting platform and an upper upsetting platform to cooperate, with a first hydraulic cylinder with a lower punch below the lower upsetting platform and a second hydraulic cylinder with an upper punch above the upper upsetting platform, enables simultaneous punching on both sides of the punched forging. With the cooperation of the connecting groove, the connecting skin of the punched forging is squeezed into the connecting groove, reducing the impact of the draft angle caused by punching. With the cooperation of the support frame and the third hydraulic cylinder, the position adjustment between the upper and lower upsetting platforms is realized, which helps to tightly fit and clamp punched forgings of different thicknesses.

[0018] This utility model achieves stable up-and-down movement of the support frame by setting a limiting rod and a sliding groove for interlocking, avoiding continuous punching during the rotation of the upper upsetting table. The upper through hole facilitates the passage of the upper punch, and the lower through hole facilitates the passage of the lower punch, enabling rapid simultaneous upper and lower punching of the forging.

[0028] Specifically, the upper surface of the upsetting table 3 is provided with a mounting base 32, and a second hydraulic cylinder 31 is provided above the mounting base 32. The end of the telescopic arm of the second hydraulic cylinder 31 is provided with an upper punch 310. The upper punch 310 moves up and down to complete the upper punching action.

[0029] It is worth adding that the upper upsetting platform 3 has an upper through hole 30 in the middle, and the upper punch 310 is slidably inserted into the upper through hole 30. The outer diameter of the upper upsetting platform 3 is compatible with the outer diameter of the lower upsetting platform 2.

[0030] In this utility model, the upper punch 310 passes through the upper through hole 30 and contacts the bottom of the forging to punch the bottom. The upper upsetting platform 3 corresponds to the lower upsetting platform 2, and stably clamps and holds the forging that needs to be punched.
