[CN 201810065449.4] Spiral tooth cold forging machine
[CN 201810065449.4] Title of Spiral Tooth Cold Forging Machine: Application Number of Spiral Tooth Cold Forging Machine: CN 201810065449.4 Applicant: Taizhou Wante Auto Parts Co., Ltd. Application Date: 2018-1-23 Patent Type: Application for Invention The present invention discloses a Spiral Tooth Cold Forging Machine. The main points of its technical scheme are: including a frame, a workbench arranged on the frame, a cold forging die arranged on the workbench, and an oil cylinder arranged on the workbench, the cold forging die includes a base, a main body, and an extrusion head. The base is fixedly connected to the end surface of the worktable facing the oil cylinder. The main body is installed on the end surface of the base facing the oil cylinder. The center of the main body is provided with a through hole. The extrusion head includes a mounting ring and an extrusion block. The mounting ring is embedded at the inner hole wall of the through hole. The extrusion block is spiral, in addition, the number of extrusion blocks is several and uniformly distributed in the circumferential direction with the axis line of the mounting ring as the center. The piston rod of the oil cylinder faces one side of the worktable, and the piston rod of the oil cylinder is perpendicular to the end face of the worktable facing the oil cylinder. Spiral teeth are produced by cold forging forming, thus there is no need to use a milling machine to mill the spiral grooves at the connecting sections one by one, thus greatly improving the production efficiency of the spiral teeth.
