Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a closed forging die set for metal forging, which is shown in fig. 1-2, and comprises a bottom plate 1, wherein the bottom plate 1 is used for supporting the whole forging die set, a lower forging mechanism is arranged above the bottom plate 1, the lower forging mechanism comprises a forging table 2, a pressing table 3 is arranged above the forging table 2, the forging table 2 is used for being matched with the pressing table 3, so that a metal piece is forged and molded, a top plate 4 is arranged above the pressing table 3, and the top plate 4 is used for mounting an electric hydraulic cylinder 5.
Specifically, the electric hydraulic cylinder 5 is fixedly installed at the top of the top plate 4, the electric hydraulic cylinder 5 is used for pushing the pressing table 3, efficient forging of metal parts is achieved, the telescopic end of the electric hydraulic cylinder 5 movably penetrates through the top plate 4, and the telescopic end is fixedly installed at the top of the pressing table 3.
Further, all fixed mounting has bracing piece 6 around the top of forging platform 2, and bracing piece 6 is used for supporting electronic pneumatic cylinder 5 and promotes press platform 3, and press platform 3 sliding connection is on bracing piece 6, roof 4 fixed mounting on bracing piece 6.
The top of forging platform 2 fixed mounting has bed die 9, and the bottom of platform 3 fixed mounting has last mould 10, and last mould 10 cooperates with bed die 9 and forms the die cavity for in upsetting process, the metalwork can be filled in the die cavity, thereby improves the shaping effect of metalwork.
During specific work, a heated metal piece is placed in the lower die 9, the electric hydraulic cylinder 5 is started, the pressing table 3 is pushed to move downwards through the electric hydraulic cylinder 5, the upper die 10 is attached to the metal piece, the upper die 10 continuously extrudes the metal piece, the metal piece is filled in the film cavity, and therefore upsetting forging of the metal piece is achieved.
In consideration of the fact that the upsetting forging and the punching forging are separately performed in the conventional forging process, only after the upsetting is completed, punching can be performed, resulting in a long process time, so that a sliding groove is formed in the bottom of the platen table 3, and the sliding groove is provided with a second spring 13, the second spring 13 is used for helping the first punching rod 14 to reset and reducing the impact of the metal piece on the electro-hydraulic cylinder 5 (it is to be noted that the torsion value of the second spring 13 is large, so that the first punching rod 14 can press the metal piece when the first punching rod 14 is in contact with the metal piece), the first punching rod 14 is slidably connected in the sliding groove, one end of the second spring 13 is fixedly connected to the inner wall of the sliding groove, the other end of the second spring 13 is fixedly connected to the first punching rod 14, and the first punching rod 14 is movably inserted into the upper die 10.
