Embodiment Construction
[0009] see Figure 1~2 , The 3T, 5T hammer forging machine step mandrel forging die related to the present invention mainly consists of a horse frame 1, a mandrel 2 and a jaw 4. Described mandrel 2 is divided into two straight sections from front to back along its length direction, and the front one straight section mandrel diameter is smaller, is referred to as small diameter section 2.1, and the back one straight section mandrel diameter is larger, is called large diameter section 2.1. The diameter section 2.2 and the tail of the large diameter section 2.2 are octagonal 5, and the mandrel 2 is horizontally placed on the horse frame 1, and the jaw 4 is placed at the octagonal end of the mandrel 2.

The invention relates to a shoulder core forging die for a 3T/5T swager and is mainly used for forging core forgings. The shoulder core forging die comprises a support (1), a core (2) and a jaw (4), wherein the core (2) is divided into two straight sections from the front to the rear along a length direction; the front straight-section core has a smaller diameter and is called a small diameter section (2.1); the rear straight-section core has a larger diameter and is called a large diameter section (2.2); the tail of the large diameter section (2.2) is an octagon (5); the core (2) is transversely shelved on the support (1); and the jaw (4) is arranged at the octagonal end of the core (2). During production, the front small diameter section core is used for performing primary expanding, and the rear large diameter section core is directly used for performing secondary expanding. Therefore, the forging time can be greatly shortened, and the energy consumption is also reduced.
Description
(1) Technical field [0001] The invention relates to a hammer forging machine, in particular to a stepped core rod forging die for 3T and 5T hammer forging machines. Mainly used for forging mandrel forgings. It belongs to the technical field of forging machinery. (2) Background technology [0002] The electro-hydraulic hammer of the 3T and 5T hammer forging machine for forgings will use several mandrels when forging forgings with a slightly larger diameter. Before the present invention was made, the mandrel rods of conventional 3T and 5T hammer forging electromechanical hydraulic hammers were straight sections with equal diameters before and after. In production, it is necessary to use a mandrel with a smaller diameter to expand the hole, and then replace another mandrel with a larger diameter for forging. In the production process, if the mandrel is replaced, one process will be added and the forging time will be increased. Second, the temperature of the forging will be r...
