The invention provides an extrusion upsetting die for forming a special-shaped crankshaft. The extrusion upsetting die comprises an upper die, a lower die and a movable female die, wherein the upper die comprises an upper die base and an upper punch sleeve fixedly connected to the lower portion of the upper die base, and an upper punch penetrates into the upper punch sleeve; the lower die comprises a lower die base and a lower punch sleeve fixedly connected to the upper portion of the lower die base, and a lower punch penetrates into the lower punch sleeve; the movable female die is disposed on the upper surface of the lower punch sleeve and comprises a left subdivision part and a right subdivision part, the left subdivision part can slide in a left-right mode along the upper surface of the lower punch sleeve, and the right subdivision part is fixed to the upper surface of the lower punch sleeve. When the left subdivision part slides rightwards to come into contact with the right subdivision part, an extrusion upsetting die cavity matched with the shape of a to-be-formed special-shaped crankshaft is defined between the left subdivision part and the right subdivision part.
Description
technical field [0001] The invention relates to the field of metal precision forging, in particular to an extrusion upsetting die for forming a crankshaft with a different sex. Background technique [0002] Special-shaped crankshaft is a common auto parts, such as figure 1 As shown, it shows a typical structure of a special-shaped crankshaft 100 , the special-shaped crankshaft 100 includes a thinner rod part 101 and shaft parts 102 and 103 located at two ends of the rod part 101 . [0003] Since the special-shaped crankshaft 100 has a special structure with a thin center and thick ends, it is difficult to remove the forging after the extrusion and upsetting of the forging is completed by common extrusion dies. Therefore, in the prior art, the extrusion and upsetting of the special-shaped crankshaft 100 is generally completed by cutting process, that is, first blanking to obtain a rod-shaped blank, and then cutting the middle part to form a finished structure with a thin cen...
