Description

Technical Field

[0001] The utility model relates to the technical field of wheel spinning processing, and particularly relates to a hoisting device for a wheel spinning die. Background Art

[0002] Spinning is to fix the metal blank to be processed on a spinning mandrel, and the main shaft of the machine tool drives the mandrel and the workpiece to rotate together. During the rotation process, pressure is applied to the processed blank through a roller. Under the action of the pressure, the blank clamped between the mandrel and the roller will undergo local plastic deformation. Finally, the local deformation expands to the entire blank under the transverse or longitudinal feeding movement of the mandrel to complete the spinning process and obtain a product with the required shape. The performance of the product after spinning is significantly improved. After spinning, the organizational structure and mechanical properties of the material change. The grain size is fine and has a fibrous characteristic, and the tensile strength, yield strength, and hardness are all significantly improved. Spinning can make the product reach a high dimensional accuracy and surface finish. During the spinning process, the roller not only has a rolling effect on the spun metal blank but also has a flattening effect, so the surface finish of the product is high.

[0003] With the increasing demand for wheel products in the market, spinning dies have different sizes and models, and the spinning dies are frequently replaced during the production process. However, the production efficiency of the existing spinning die hoisting device during use is relatively low, and the operation is also relatively complex.

[0004] For example, the Chinese utility model patent with the authorization announcement number CN218893363 U discloses a hoisting device for a hub spinning die, which includes a top plate and a fixed box. A reel assembly is arranged in the fixed box. A hanging plate and a placing plate are arranged below the top plate. The hanging plate is connected to the reel assembly through four first suspension ropes, and the placing plate is connected to the hanging plate through four second suspension ropes. Moreover, the reel assembly is connected with a positioning assembly through a third suspension rope. The moving block is driven to move upward relative to the positioning cylinder through the third suspension rope, so that the pushing block drives the spring plate and the positioning plate to move outward, so that the hub die can be lifted by the positioning plate, and then the hub is transferred to the placing plate. During the long-distance hoisting process, the position stability of the die is improved through the placing plate; the threaded cylinder is disassembled from the first threaded shaft, so as to use the third suspension rope and the positioning assembly for hoisting, or the threaded cylinder and the bolt are used to connect and hoist the workpiece provided with a through hole, improving the use flexibility of the hoisting assembly. However, the structure of this hoisting device is relatively complex, and it cannot be applied to the hoisting and transfer of all sizes of wheel spinning dies, and the production efficiency is relatively low.
