Description
Technical field
The utility model is related to technical field of automobile accessories, and in particular to one kind being suitable for the molding sizing die of automobile axle housing
Tool.
Background technology
Previous uses in Steel Sheet automobile axle housing, is that steel plate is cut blanking at two blanks, by two blanks
Two arc-shaped groove profile parts, machining commissure, then by two arc-shaped groove profile parts to being welded into axle housing master are struck out respectively
Body, then rear cover of burn-oning is at axle housing.So being welded into after three pieces of steel plate puncheds of an axle housing.It produces in this way
Axle housing, since weld seam is long, welding quality require it is high, if control is improper, it is easy to occur commissure fatigue life it is low,
Permeability and other issues.Because three blocks of steel plates will cut out blanking respectively, stock utilization is low, and production procedure is long.
The patent of applying date 2012.07.27, application number 201210265116.9 disclose a kind of automobile axle housing forming side
Method, is subsequently filled and is squeezed using sealed pipe fittings and be molded by the way of graceful liquid：
Such as the 0053rd section of record of its specification：Second intermediate product 2 is put into lower cavity die 52, press downlink, fovea superior
Mould 51 compresses the second intermediate product 2, and left and right punch 53 moves ahead, and is inserted into the second intermediate product 2 to seal up two end.
The highly pressurised liquid of 45-75MPa is injected from the through-hole of left and right punch 53, left and right punch 53 continues to move ahead, and pushes tube wall, along
The feeding inward of tube axis direction.Under the action of interior high pressure and axial thrust, pipe stage casing material starts plastic expansion deformation,
It moves outward again, until filling up die cavity, forming obtains product 3 among third.
Although above-mentioned manufacture craft can cancel weld seam, interior high-pressure molding technique is easy to happen buckling, corrugation, cracking
The defects of, and interior high-pressure process needs great tonnage hydraulic machine as clamping pressure machine, and need accurate closed-loop control system
System, and rely on high-pressure medium and operated.
Therefore need to be related to it is a kind of can equally reduce weld seam, and implementing process is more reasonable, requires device relatively low
Forming method.
