Description

Technical Field

[0001] The utility model relates to a tooling improvement of forging equipment, in particular to a high-efficiency replacement device for a rough plate of a free forging machine. Background Art

[0002] A forging press is a processing equipment used to forge metal products. It deforms the metal through the downward pressure to achieve the desired shape. The forging press itself only has downward pressure. If it needs to be processed into certain shapes, such as rings, it needs to be achieved through tooling. Therefore, it is necessary to replace the pier plates of different shapes during the processing. The usual replacement process requires frequent correction and alignment. The long replacement time will cause the hot forged workpiece to cool down and fail to achieve the expected processing purpose. Therefore, improvement is needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a high-efficiency replacement device for a rough plate of a free forging press.

The fixed gripping plate is a basic fixed structure, and the replaceable working plate is the main processing structure that can be replaced according to processing requirements. The fixed gripping plate has a positioning structure for quickly aligning with the replaceable working plate, eliminating the process of repeated operations, saving replacement time, and using a claw structure for fixing, the unlocking and locking processes can save time and improve work efficiency.

[0005] Furthermore, the fixed grab plate includes a base plate body, an upper fixing, a positioning guide column, and a claw structure. The base plate body is horizontally arranged, and the upper fixing is fixed on its upper surface and fixedly connected to the stamping working structure of the forging machine. The positioning guide column is arranged on the lower surface of the base plate body and vertically extends downward to form. The claw structure is arranged on the side of the base plate body and extends downward to set a clamping part. The length of the clamping part corresponds to the physical thickness of the replaceable working plate. The positioning guide column has high structural strength and is arranged vertically downward. The downward pressure of the forging machine is used to achieve rapid guiding and matching. The positioning guide column can be arranged in a diagonal distribution or a three-point non-collinear distribution to prevent problems such as reverse installation. It can be adjusted according to the structure of the working plate. The claw structure can rotate freely when loosened, so it can automatically enter the clamped position along the edge during the descending process, and then lock it to complete the replacement.

[0006] Furthermore, the upper surface of the replaceable working plate contacts the fixed gripping plate and is formed with a positioning guide hole, the positioning guide column is arranged opposite to the positioning guide hole, and a fixing groove for embedding the claw structure is formed on the side of the replaceable working plate. The positioning guide holes are arranged opposite to each other, and the fixing grooves on the side are also arranged correspondingly, so that the replaceable working plate is a solid structure with uniform texture as a whole.

[0007] Furthermore, the claw structure includes a swing claw, a pin shaft, and a locking hole. The swing claw is rotatably connected to the side of the base plate body through the pin shaft, one end of the swing claw is embedded in the entity structure of the base plate body, and the locking hole is set through the base plate body and the swing claw. The locking pin is inserted into the locking hole and maintains the swing claw in a gripping and fixed state. The swing claw can rotate with the pin shaft in the unlocked state, and the locking hole is a rigid through-locking form. The locking state is reliable and meets the processing requirements.

[0008] Furthermore, the positioning guide column is cylindrical, and the edge of its end is arc-shaped or beveled, and the shapes in the positioning guide hole are relatively arranged. The cylindrical shape has a good guiding effect, and the side circular surface can be set with a certain taper, which has a guiding effect, and the arc edge or bevel edge of the end can reduce wear and extend the service life.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the tooling structure of a forging machine, is a structure that can be quickly replaced according to processing requirements, has the advantages of quick loosening, quick guiding, and quick locking, has high work efficiency, can reduce the processing time of hot forgings, and reduce energy consumption.
