The invention discloses a pre-upsetting mould for a car semi-axis blank and relates to a processing mould for car parts. The pre-upsetting mould is mounted on an upright four-column pre-upsetting hydraulic press, a heated circular steel bar is inserted into the pre-upsetting mould, metals are gathered according to the shape of the inner cavity of the pre-upsetting mould and an end part is pre-upset and thickened. The pre-upsetting mould comprises a male mould, an upper mould sleeve, an outer mould sleeve, a middle mould sleeve and a lower mould, wherein the male mould is fixed on a connectingplate I through a male mould fixing plate and a bolt I; the connecting plate I is mounted on the upper sliding block of the pre-upsetting hydraulic press through a T-shaped slot bolt; the upper mouldsleeve is sleeved in the hole of the outer mould sleeve; the outer mould sleeve is mounted on a connecting plate II through a bolt III; the connecting plate II is mounted on a lower sliding block of the pre-upsetting hydraulic press through a bolt II; the middle mould sleeve is mounted in the hole of the outer mould sleeve; a flange is arranged at the other end of the outer mould sleeve through abolt IV; the lower mould is a Haversian mould; and the lower mould is mounted on an operating platform of the pre-upsetting hydraulic press through a Haversian mould clamping device.
Description
Technical field [0001] The invention relates to a processing mold for automobile parts, in particular to a pre-upsetting mold for automobile half-shaft blanks, and is also suitable for processing molds for pre-upsetting other rod blanks with flanges at the ends. Background technique [0002] Automobile half shafts and other similar rods with flanges at the ends are processed by inserting the heated round steel into the mold, accumulating the metal according to the shape of the mold cavity, pre-upsetting and thickening the end, and then processing it with a pendulum mill Flange out to form semi-shaft blank. This technology has been maturely applied abroad. At present, simple parting molds are still used in China to pre-upset with air hammers or single-column hydraulic presses. The labor intensity of workers is high, the production efficiency is low, and safe production is not guaranteed. Summary of the invention [0003] In order to solve the above technical problems, the present ...
