Warm forging die guide structure with upward ramming function

Abstract

The invention discloses a warm forging die guide structure with the upward ramming function. The warm forging die guide structure comprises an upper die base, a lower die base and a spraying and ramming assembly; the upper doe base is provided with a back extrusion punch and a cavity, wherein the cavity is used for containing a ramming rod; the lower die base is provided with a concave cavity matched with the back extrusion punch; the spraying and ramming assembly comprises a connecting base, a spraying ring and a ramming ring, wherein the spraying ring and the ramming ring are fixedly connected to the connecting base; the spraying ring is located at the upper end of the ramming ring; the ramming rod comprises a first rod body and a second rod body, wherein the diameter of the first rod body is greater than the diameter of the second rod body; the cavity comprises a first cavity body and a second cavity body, wherein the aperture of the first cavity body is greater than the aperture of the second cavity body, the aperture of the first cavity body is greater than the diameter of the first rod body, the aperture of the second cavity body is less than the diameter of the first rod body, and the aperture of the second cavity body is greater than the diameter of the second rod body; and the end parts of the second rod body of the ramming rod are fixedly connected to the connecting base. The warm forging die guide structure has the advantage that the phenomenon that a warm forging back extrusion forge piece wraps the back extrusion punch can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of metal forming, and more specifically relates to a guide structure for a warm forging abrasive tool with feeding on it. Background technique [0002] As an extension of the field of cold forging technology, warm forging is more and more used in forging production with large deformation that is difficult to achieve in cold forging technology. Due to thermal expansion and cold contraction of materials, warm forging and reverse extrusion products are prone to wrapping reverse extrusion punches during the material return process. However, conventionally, the feeding structure and the guiding structure conflict, which cannot meet the production and quality requirements. Contents of the invention [0003] The purpose of the present invention is to provide a warm forging die guide structure with feeding material that can effectively solve the phenomenon that the warm forging reverse extrusion forging contains reverse ext...
