Abstract
The invention relates to a punching and shearing method of a stator punched sheet and a rotor punched sheet of a high-efficiency energy-saving motor. The punching and shearing method specifically comprises the following steps: punching the stator punched sheet and the rotor punched sheet of the motor by a falling composite die at one time, wherein the falling composite die comprises a convex die and a concave die; the convex die comprises a stator outer edge convex die, a stator inner edge groove convex die, a rotor outer edge groove convex die and a rotor inner edge hole convex die; the stator outer edge convex die and the rotor inner edge hole convex die are concentrically arranged; the convex die is matched with the convex die; laminating the stator punched sheet and the rotor punched sheet of the motor punched at one time by the falling composite die to form a motor stator and a motor rotor, wherein the overlapping coefficient is high, the burrs of the punched sheets are extremely small, the laminated iron core has better concentricity, and the manufactured motor has low electromagnetic noise, and the efficiency index can reach the efficiency requirement in the standard GB18613-2012.
Description
Technical field
The present invention relates to a kind of stator punching of energy-saving efficient motor and the punching-shearing method of rotor punching.
Background technology
Along with high efficiency motor replaces the update of general effect motor, the efficiency index of its high efficiency motor than general effect motor on average up to 2 ~ 3%, need to reduce dominant loss, iron loss is also one of them, and silicon steel sheet is main permeability magnetic material, it also exists the problem of shear stress in punching process, the performance of this factor to motor has a certain impact, high efficiency motor not only will adopt low-loss permeability magnetic material to reduce the wastage, also need to select rational technique to reduce the wastage in manufacturing process, to reach high efficiency object.
The punching-shearing method of original motor stator punching and rotor punching is: the first step: be washed into stator and rotor disk, and as shown in Figure 1, this step needs blanking die one pair for stator and rotor disk; Second step: stator and rotor disk are separated and form stator punching finished product and rotor punching semi-finished product, and as shown in Figure 2, as shown in Figure 3, this step needs stator punching compound die one pair to rotor punching semi-finished product to stator punching finished product; 3rd step: punching rotor punching semi-finished product form rotor punching finished product, and as shown in Figure 4, this step needs rotor punching compound die one pair to rotor punching finished product.From the course of processing of punching, become finished product by raw material and need comparatively multiple operation, and need more punch die, and the punching of rushing out like this to laminate into the concentricity of stator core poor, especially the concentricity of stator punching finished product and rotor punching finished product is comparatively large, and burr is comparatively large in addition, and repeatedly pressure coefficient is low, noise of motor is also large, and loss is also large.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of stator punching of energy-saving efficient motor and the punching-shearing method of rotor punching.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stator punching of energy-saving efficient motor and the punching-shearing method of rotor punching, be specially: motor stator punching and rotor punching once rush material by same pair of blanking compound die and go out.
Blanking compound die comprises punch, die, and punch comprises marginal pore punch in stator outer rim punch, stator inner edge geosynclinal convex mould, rotor periphery geosynclinal convex mould, rotor, and stator outer rim punch is installed with in rotor, marginal pore punch is concentric, and die and punch match.
Stator outer rim punch is used for the outer rim that punching forms stator punching, stator inner edge geosynclinal convex mould is used for the inner edge groove that punching forms stator punching, rotor periphery geosynclinal convex mould is used for the border groove that punching forms rotor punching, and in rotor, marginal pore punch is used for punching formation rotor inner hole.
The invention has the beneficial effects as follows: once rushed the motor stator punching and rotor punching expecting to go out by same pair of blanking compound die, stacking formation motor stator, rotor, repeatedly pressure coefficient is high, punching burr is very little, iron core concentricity after laminating is better, the motor electromagnetic noise made is low, and efficiency index can reach the efficiency requirements in standard GB18613-2012.
