Description

Technical Field

[0001] This utility model belongs to the field of forging shaping technology, and in particular relates to a shaping tooling for irregular forgings. Background Technology

[0002] Irregularly shaped ring forgings have complex shapes, and it is difficult to control their dimensions during rolling, which can easily lead to errors. At the same time, during the rolling process, dimensional control problems can easily cause the dimensions to fail to meet the design requirements of the forging, or inconsistent rolling dimensions can lead to uneven deformation of batch forgings, thus affecting the consistency of the microstructure and properties of the forgings. Therefore, forgings need to be further shaped after rolling, which requires the use of forging shaping fixtures.

[0003] Chinese patent application CN216461502U discloses a forming fixture for irregularly shaped ring forgings, including a fixed ring seat, a fan-shaped lower die, a fan-shaped upper die, and an upper anvil. The fan-shaped lower die is fixed on the fixed ring seat with its concave surface facing upwards. The rolled irregularly shaped ring forging is placed on the fan-shaped lower die. The fan-shaped upper die is located above the irregularly shaped ring forging with its concave surface facing downwards. The upper anvil is fixed above the fan-shaped upper die. This utility model is easy to operate, requiring only repeated extrusion and rotation operations. By extruding and shaping the forgings through the arc-shaped concave surfaces of the fan-shaped lower and upper dies, the dimensional accuracy of the forgings can be effectively controlled, and defects such as ellipses and flared mouths after rolling can be eliminated. It also ensures that the dimensions of the forgings meet the design requirements, and the outer ring surface of the forging is not damaged after rolling. During the forming and extrusion process, the force on all parts of the outer ring surface of the forging is uniform, resulting in uniform deformation and microstructure properties of all parts of the forging.

[0004] Although this patent can effectively control the dimensional accuracy of forgings and eliminate defects such as ovals and flared mouths after forging by extruding and shaping the arc-shaped concave surfaces of the fan-shaped lower die and fan-shaped upper die, it lacks an automatic rotation function. Since most irregular forgings are large in size and heavy in weight, workers need to use tools or forklifts to complete the rotation operation of irregular forgings. This results in workers spending a lot of time shaping irregular forgings, which is not conducive to its use.

[0005] To address these issues, we provide a forming fixture for irregularly shaped forgings. Utility Model Content

[0006] The purpose of this utility model is to provide a special-shaped forging forming fixture. By combining the workpiece rotation component and the anti-drop component, it solves the problem that the existing special-shaped forging forming fixtures do not have an automatic workpiece rotation function. After each forming, the workpiece needs to be rotated by the operator using tools or equipment, which leads to the operator spending a lot of time and reducing the forming efficiency when forming special-shaped parts.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a forming fixture for irregularly shaped forgings, comprising a base, a workpiece rotation assembly, and an anti-drop assembly. A lower mold is fixedly connected to the top of the base, and an upper mold is positioned on top of the lower mold. The workpiece rotation assembly includes a moving mechanism, the bottom of which is fixedly connected to the base.

A handwheel is positioned on the rear of the lifting plate, and a driving gear is fixedly connected to the front of the handwheel through the lifting plate. The anti-drop assembly includes a housing, the rear of which is fixedly connected to the lower mold. Electric push rods are fixedly connected to both sides of the bottom of the housing's inner cavity. Opposite sides of the two electric push rods penetrate the housing and are fixedly connected to a connecting frame. A limit frame is fixedly connected to the rear of the connecting frame.

[0009] The present invention is further configured such that the moving mechanism includes a guide rail, the bottom of the guide rail is fixedly connected to the base, a movable platform is slidably connected to the surface of the guide rail, and the top of the movable platform is fixedly connected to a hydraulic cylinder. The guide rail is used to limit the movable platform, and the movable platform can slide back and forth on the surface of the guide rail, which facilitates the adjustment of the position of the rotating roller.

[0010] The present invention is further configured such that a sliding rod is fixedly connected to the front and rear sides of the top of the movable platform, and a sliding sleeve is slidably connected to the surface of the sliding rod. The front and rear sides of the lifting plate are fixedly connected to the sliding sleeve. The sliding rod and the sliding sleeve can limit the lifting plate so that it will not deviate or shake during the up and down movement.

[0011] The present invention is further configured such that positioning frames are fixedly connected to both sides of the upper mold, and a vertical plate is provided in the inner cavity of the positioning frame. The bottom of the vertical plate is fixedly connected to the base. A handle is fixedly connected to the opposite side of the two positioning frames. The positioning frames and the vertical plate can limit the use position of the upper mold, so that it can accurately cooperate with the lower mold to shape the irregular part. The handle can facilitate the worker to remove the upper mold.

[0012] The present invention is further configured such that handles are fixedly connected to both sides of the lifting plate, a stabilizing bracket is movably connected to the front side of the rotating roller, and the bottom of the rear side of the stabilizing bracket is fixedly connected to the lifting plate. The handles are used to control the position of the lifting plate and the rotating roller, and the stabilizing bracket improves the support performance of the rotating roller so that it will not deform when lifting irregularly shaped parts.

[0013] The present invention is further configured such that the rear side of the rotating column is movably connected to the lifting plate via a bearing, and through holes are provided on both sides of the equipment housing for use with the electric push rod. The bearing can increase the stability of the rotating column during rotation, and the through holes facilitate the electric push rod to control the position of the connecting frame.

[0014] The present invention is further configured such that limiting shells are fixedly connected to both sides of the top of the base, and limiting rods are slidably connected to the inner cavity of the limiting shells. The top of the limiting rods is fixedly connected to the limiting frame.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model uses a workpiece rotation assembly, with a movable table on the guide rail driving the hydraulic cylinder and lifting plate to move, enabling the rotating roller to enter the interior of the irregular part. The hydraulic cylinder controls the rotating roller to lift the irregular part, and the handwheel drives the drive gear and the driven gear on the rotating column to rotate. The driven gear drives the rotating roller to rotate, and the rotating roller controls the rotation of the irregular part to change its orientation. This replaces manual handling and rotation, and realizes rapid rotation during forging shaping. It eliminates the need to use forklifts or tools to manually rotate the workpiece, thus improving the efficiency of irregular part shaping.

[0018] 2. This utility model uses an anti-detachment component. Two electric push rods installed inside the equipment housing synchronously push the connecting frames and limiting frames on both sides to move laterally, so that the limiting frames are stuck on both sides of the lower mold, which can block the front and rear sides of the lower mold. When the forging is squeezed and shaped by the upper mold, the limiting frame fits against the outer edge of the workpiece to form an anti-detachment groove. At the same time, the limiting shell and the limiting rod constrain the linear movement trajectory of the limiting frame, ensuring that the irregular forging is always in the cavity of the lower mold during the shaping process, preventing the irregular part from detaching from the inner cavity of the lower mold.

[0033] The working principle of this utility model is as follows: The irregularly shaped part to be shaped is placed inside the lower mold 2. The upper mold 3 is positioned on top of the irregularly shaped part using the cooperation of the vertical plate 7 and the positioning frame 6. The irregularly shaped part is shaped by a press. When the irregularly shaped part needs to be rotated, the upper mold 3 is lifted by the handle, and the rotating roller 44 is inserted into the annular irregularly shaped part using the guide rail 411 and the movable table 412. The hydraulic cylinder 48 is activated, causing the rotating roller 44 to lift the irregularly shaped part. Then, the handwheel 46 is rotated. The handwheel 46, in cooperation with the drive gear 47, controls the rotation of the driven gear 45 and the rotating roller 44. The rotating roller 44 controls the rotation of the irregularly shaped part, changing it to the specified orientation. After this, the hydraulic cylinder 48 is reset and the rotating roller is pulled out. After the upper mold 3 is lowered, the roller 44 can continue to perform shaping operations on the irregular parts through the press, replacing manual handling and rotation, realizing rapid rotation during the shaping of irregular forgings, eliminating the need to use forklifts or tools to manually rotate the workpiece, and improving the shaping efficiency of irregular parts. Before shaping, the electric push rod 52 is turned on. The electric push rod 52 cooperates with the connecting frame 53 to control the movement of the limit frame 54 along the straight trajectory constrained by the limit shell 10 and the limit rod 11, so that the limit frames 54 on both sides are engaged with the front and rear edges of the lower mold 2 to form a closed protection. When the press drives the upper mold 3 to press down, the limit frame 54 and the outer edge of the workpiece form an anti-detachment groove to prevent the irregular parts from detaching from the inner cavity of the lower mold 2 due to stress deformation during the shaping process.
