Description

Technical Field

[0001] The utility model relates to the technical field of operation, in particular to a quick cutting device for forgings. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation to obtain a forged piece with certain mechanical properties, a certain shape and size. The Chinese utility model patent, with the authorization announcement number "CN214079099U", discloses a rapid cutting device for high-precision forged pieces, and a cutter is fixedly installed on the lower side of a cutter base by screws, and an assembly groove is provided on the outer wall of the cutter base, in which a planer roller is rotatably installed, and a pad is fixedly installed on the lower part of the device body. The device body is a stamping device. After the cutter cuts the workpiece to be processed, the hydraulic rod continues to move downward until the planer roller contacts the cross section of the workpiece, and the planer roller rotates under the drive of the motor to cut and grind the cross section. The cutting method of the device is stamping cutting, and after cutting, a cross section processing function is provided, which performs simple processing on the cross section with a short process to reduce the roughness of the cross section, thereby facilitating subsequent processing, shortening the workpiece processing cycle and improving production efficiency.

[0003] The above technical solution uses a throwing hole to collect the waste after cutting, and at the same time avoids the cutter hitting the pad to cause damage to the pad and the blade. The main body of the device is a stamping device. After the cutter cuts the workpiece to be processed, the hydraulic rod continues to move downward until the planer roller contacts the cross section of the workpiece. The planer roller rotates under the drive of the motor to cut and grind the cross section. However, the above technical solution still has certain defects. For example, the cutter is fixedly installed on the lower side of the cutter base of the above equipment by screws. However, when the cutter is used for a long time and needs to be maintained and repaired, the staff needs to remove the screws with the help of tools and then remove the cutter. This operation is complicated and inconvenient to remove the cutter, which increases the workload of the staff. Utility Model Content
