The invention relates to a die set for forging contracted handles of screw taps. The die set comprises an upper sleeve die and a lower sleeve die. The upper sleeve die comprises a sleeve, a first side protrusion and a second side protrusion and is provided with a first oil groove, an upper sleeve is arranged in the upper sleeve die, and a first through hole is formed in the upper sleeve. A die core is arranged between the upper sleeve die and the lower sleeve die, a second through hole and a hard alloy die layer are formed in the die core, and the second through hole is composed of a first-stage hole, a second-stage hole and a third-stage hole. The die core is provided with a second oil groove. A lower sleeve is arranged in the lower sleeve die, a third through hole is formed in the lower sleeve, a fourth through hole is formed in the lower sleeve die, and the lower sleeve die is provided with a third oil groove. The die set is precise in structure and high in loading capacity and can improve the machining efficiency, and the forging formability of the contracted handles is high.
Description
technical field [0001] The invention relates to a die set for tap shank reduction forging, which belongs to the technical field of tap shank reduction processing. Background technique [0002] A tap is a tool for processing internal threads, which can be divided into spiral taps and straight-edged taps according to the shape. The channel for punching the head and placing the shank ensures the formability of the shrinking shank forging and stretching, but the modules in the prior art have unreasonable structural design, poor pressure bearing capacity, and short service life, which lead to the formation of the shrinking shank forging Poor performance, low processing efficiency and other issues. Contents of the invention [0003] The object of the present invention is to address the defects of the prior art and provide a die set for tap shank reduction forging, which has a precise structure, strong pressure bearing capacity, good formability for shank reduction forging, and ...
