Abstract
The present invention mainly uses carbon steel material：Roll bending, middle plate, round steel etc. produce blank plectane, are spun into tubular shell pattern, by late stage process machine-shaping.The automobile wheel edge reducer shell is that carbon steel material uses the integral rotary press modelling of spinning machine, because the characteristic of carbon steel material determines that carbon steel material automobile wheel edge reducer shell in actual use will not be because leakage scenarios occur in the defects such as casting shrinking hole, shrinkage porosite.The mechanical performance index of carbon steel material is higher than founding materials：Carbon steel material tensile strength is more than 400Mpa, and founding materials tensile strength is 250Mpa.The automobile wheel edge reducer shell spinning process manufacture of carbon steel material is the cold working metal moulding process for being rolled, being extruded to carbon steel material using shear spinning technology.
Description
Technical field
Automobile wheel edge reducer shell is the important key components and parts in heavy-load automobile chassis, the main component parts of hub reduction gear
One of, its mechanical performance and performance require higher, are related to technical field of automobile parts, including automobile wheel edge decelerator cylinder
Shape housing（Hereinafter referred to as housing）.
Background technology
Automobile wheel edge reducer shell mainly uses casting technique in the past, due to the special tectonic of housing, causes casting
Barrel differs larger with the wall thickness of casting bottom, and wall thickness height is higher, in the molten iron casting, process of setting in casting process,
Casting easily causes the Some Common Defects such as shrinkage cavity and porosity.Under automobile actual working state, housing will bear larger torsion
Rated pressure and the fluid in motion are filled with square, housing, therefore can not have an impact intensity in shell casting and possible
Cause the shrinkage cavity and porosity phenomenon of permeability.There is different degrees of shrinkage cavity and porosity and show in the shell casting that current casting technique is produced
As, so that cause automobile wheel edge decelerator to have different degrees of leakage problems when in use, and casting technique can cause casting
Surface roughness is poor, and housing needs whole turnery processings, so housing moulding process is complex.Subtracted according to above automobile wheel edge
The defect of fast device shell casting, my company develops a kind of carbon steel material automobile wheel edge reducer shell, and the automobile wheel edge slows down
Device housing is carbon steel material, using the integral rotary press modelling of spinning machine, because the characteristic of carbon steel material determines carbon steel material automobile
Hub reduction gear housing is not in leakage of oil situation in actual use.The automobile wheel edge reducer shell of carbon steel material also changes
The shortcoming low to air environmental pollution and casting production efficiency that traditional mode of production housing uses casting method to produce is become.
The content of the invention
The present invention mainly uses carbon steel material：Roll bending, middle plate, round steel etc. produce blank plectane, are spun into tubular
Housing pattern, by late stage process machine-shaping.This housing using carbon steel sheet as material can be effectively pre- anti-fracture, intensity
Height, service life is long, is not susceptible to deformation, can effectively prevent the automobile wheel edge decelerator because caused by being deformed hub reduction gear
The generation of housing oil leakage phenomenon, improves product qualification rate.Will not occur cold shut, crackle, shrinkage cavity and penetrability as cast member
Defect.
Brief description of the drawings
Fig. 1 is automobile wheel edge reducer shell appearance schematic diagram.
Beneficial effects of the present invention are embodied in：1st, the automobile wheel edge reducer shell is that carbon steel material uses the integral spinning of spinning machine
Shaping, because the characteristic of carbon steel material determines that carbon steel material automobile wheel edge reducer shell in actual use will not be because of casting
There are leakage scenarios in the defects such as shrinkage cavity and porosity.
2nd, the mechanical performance index of carbon steel material is higher than founding materials：Carbon steel material tensile strength is more than 400Mpa, casting
Tensile strength is 250Mpa.
3rd, the automobile wheel edge reducer shell spinning process manufacture of carbon steel material is to carbon steel material using shear spinning technology
The cold working metal moulding process rolled, extruded, is different from the metal material melting, cast, cooling procedure of casting, changes
The environmental pollution that conventional cast production is caused, with energy-saving advantage.
4th, spinning process produces car deceleration device wheel side housing, reaches the productive temp of 1 per minute, production efficiency is than casting
Method production improves more than 3 times.
