Abstract
A process for manufacturing the motor casing with Al-alloy without cutting to internal hole includes such steps as hot squeezing of Al-alloy ingot by squeezing die to obtain section, straightening, cutting short, hydraulic shaping, and fixating its shape by ageing at 150-200 deg.C for 2-6 hr.
Description
Technical field
The present invention relates to a kind of motor housing production technology, particularly a kind of process for producing deforming aluminium alloy case of electric machine without need of cutting internal hole.
Background technology
The main technique of producing motor housing at present is casting (ferrous metal), die casting and hot extrusion (aluminium alloy), particularly hot extrusion technique is widely used, but because the production technology precision of casting, die casting, hot extrusion is not enough, must cause the loss of waste in man-hour and material through press-fiting stator after the turning processing.
Summary of the invention
The production technology precision that the objective of the invention is to solve the hot extrusion of producing motor housing in the prior art is not enough, must cause the problem of the loss of waste in man-hour and material through press-fiting stator after the turning processing.The present invention designs process for producing deforming aluminium alloy case of electric machine without need of cutting internal hole, it is characterized in that: have the following step (1) with extrusion die the aluminium alloy billet to be squeezed into the motor housing section bar with heat extruder, (2) with rectangular motor housing section bar alignment, (3) the motor housing Saw of section bar after the alignment is cut into the motor housing of Len req, (4) pressed motor housing to carry out shaping with hydraulic press sizing die, (5) were carried out timeliness with 2-6 hour with the motor housing after the shaping and are formalized under 150-200 degree centigrade condition.Advantage of the present invention is to have exempted turning machine processing directly to obtain the alloy electric machine shell by the hot extrusion correction process, and material-saving saves time.
Following embodiment elaborates to the present invention,
Embodiment at first designs hot-extrusion mold according to the designing requirement of product, with extrusion die the aluminium alloy billet is squeezed into the motor housing section bar at heat extruder then, with rectangular motor housing section bar alignment, motor housing Saw of section bar after the alignment is cut into the motor housing of Len req, pressed motor housing to carry out shaping with hydraulic press sizing die, motor housing after the shaping was carried out timeliness with 3 hours under 200 degrees centigrade condition formalize, after the shaping and the motor housing after timeliness setting high intensity and dimensional accuracy are arranged, stator can directly be installed reduce production man-hour and material cost widely.
