Abstract
The invention discloses a cold extruding mold for a shaft-type component of an automobile transmission. The cold extruding mold comprises a lower mold base and an upper mold base, wherein the lower mold base is installed on a lower working platform of an oil press and sequentially connected with a lower mold through a lower cushion plate and a lower cushion; lower mold sleeves are respectively sleeved outside the lower cushion plate and the lower cushion; a lower stress ring is sleeved outside the lower mold, the outer edge of the lower stress ring is provided with a lower female connector, the lower end of the lower female connector is provided with a flange which is turned outwards, and the flange is fixedly connected with the lower mold sleeve; the upper mold base is installed on an upper working platform of the oil press and connected with an upper mold through an upper cushion plate; an upper sleeve is arranged outside the upper cushion plate, an upper stress ring is arranged outside the upper mold, and one end of the upper stress ring is fixedly connected with the upper sleeve; the upper mold and the lower mold are respectively provided with a mold cavity which is matched with a shaft. By adopting the cold extruding mold, the energy is saved, the working environment is improved, raw materials can be saved, and the machining cost can be reduced.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of cold extrusion die of automotive transmission axial workpiece.
Background technology
The automotive transmission axial workpiece, comprise an axle, two axles and jackshaft, wherein, an axle usually and gear be made of one, front end is bearing on the bearing of engine flywheel inner chamber; Two axle forenecks are arranged in the inner chamber that an axle often meshes gear ring by bearing; Jackshaft has rotary and fixed two kinds.At present, the transmission shaft class adopts the forge hot mode to process more, is about to the blank METAL HEATING PROCESS to higher than forging processing more than recrystallization temperature.Yet in the forge hot mode, heating process need to expend mass energy, if use the unclean energy also can cause environmental pollution, and fortunately cause blank metal cutting loss in forge hot processing, urgently improve.
Summary of the invention
For the problem of prior art existence, the object of the invention is to propose a kind of cold extrusion die of automotive transmission axial workpiece, to save the energy, improve working environment, and save material, cut down finished cost.
A kind of cold extrusion die of automotive transmission axial workpiece comprises:
Die shoe, be arranged on the lower workbench of hydraulic press, by lower bolster, with underlay, with counterdie, is connected successively; Described lower bolster and described underlay outer cover are provided with lower die-sleeve; Described counterdie is arranged with lower circle stress outward, and described lower circle stress outer rim is provided with lower female connector, and described lower female connector lower end is provided with the flange of outwards routing up, and described flange and described lower die-sleeve are fixed;
Upper bolster, be arranged on the upper workbench of hydraulic press, by upper padding plate, with patrix, is connected; Described upper padding plate is provided with cover outward, and described patrix is provided with the upper stress circle outward, and described upper stress circle one end and described upper cover are fixed;
Described patrix and described counterdie are provided with the die cavity be complementary with axle.
Preferably, described underlay and described lower bolster are bolted.
Preferably, described lower die-sleeve is fixed by bolt and described die shoe.
Preferably, described lower circle stress and described underlay are bolted.
Preferably, the flange of described upper set upper side for outwards routing up, fix by bolt and described upper bolster.
