Drawings
Fig. 1 is a schematic structural diagram of a warm forging forward extrusion die structure according to an embodiment of the present invention.
Detailed Description
Fig. 1 schematically shows a warm forging forward extrusion die according to an embodiment of the present invention. As shown in fig. 1, the warm forging positive electrode die includes a positive extrusion die 1, a middle ring 2, and an outer ring 3.
The middle ring 2 is flush with the outer ring 3, and the middle ring 2 and the outer ring 3 are universal dies. The end face of the forward extrusion die 1 is higher than or flush with the end faces of the middle ring 2 and the outer ring 3, and the forward extrusion die can be used for forward extrusion dies with various length specifications. The forward extrusion die 1 is provided with a cavity for extruding a workpiece, and the side wall of the cavity is in a large arc shape. The middle ring 2 is sleeved outside the forward extrusion die 1. The outer ring 3 is sleeved outside the middle ring 2. The inside wall of well circle 2 and the laminating of the outside wall of just crowded mould 1 mutually, the outside wall of well circle 2 and the laminating of the inside wall of outer lane 3 mutually. The diameter of the middle ring 2 is gradually increased from one end to the other end, and the middle ring is in a circular truncated cone shape. The inner surface of the outer ring 3, which is contacted with the middle ring 2, is provided with a spiral groove, and the end part of the outer ring 3 is provided with a water inlet a and a water outlet b. The water inlet a is communicated with one port of the spiral groove, and the water outlet b is communicated with the other port of the spiral groove. Specifically, the water inlet a and the water outlet b are located on the same end face of the outer ring 3, a water inlet pipe and a water outlet pipe are respectively arranged in the outer ring 3, the water inlet a is communicated with the spiral groove through the water inlet pipe, and the water outlet b is communicated with the spiral groove through the water outlet pipe.
The utility model discloses a three-piece structural formula mould: the outer ring 3 is provided with a spiral groove cooled by circulating water, and the mould is cooled by the circulating water; the deformation part of the inner ring forward extrusion die 1 adopts a large arc connection form, and the stress direction during extrusion is decomposed by using the large arc, so that the service life of the forward extrusion die 1 is prolonged; the middle ring 2 is used for separating the outer ring 3 from the forward extrusion die 1 so as to facilitate the replacement of the forward extrusion die 1.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
