Embodiment Construction

[0013] The present invention is further set forth below through the accompanying drawings of the description;

[0014] As shown in Figure 1, a multi-row dislocation punching process for a solid rotor motor. The process steps are: coil material unwinding and leveling feed → high-speed punching machine → multi-row dislocation progressive die → output of stator and rotor punching sheet 1 (and by-products); punching sheet 1 rotor only drops discs, not punching shafts The discs dropped from the holes can also be used as stator and rotor cores of small motors, which improves the utilization rate of silicon steel sheets; the outer circle of the same motor model is the same as the shaft hole, and the space between the two tangent circles is used to arrange another row of tangent circles. The range of cutting can be arranged between 2 and 8 columns.

[0015] In the production process, with the help of n\NcRF-500-1000 feeding leveler, feeding → passing through a 300-600-ton high-speed ...

Abstract

The invention provides a multicolumn staggered punching process of an electric motor with a solid rotor. The multicolumn staggered punching process of the electric motor with the solid rotor comprises the steps of: unreeling, leveling and feeding a roll material; punching at a high velocity; feeding the punched roll material in a progressive mould in a multicolumn staggered manner; and outputting stator and rotor punching sheets (and by-products). By the adoption of the multicolumn staggered punching process and the reduction of the width of a strip material, a feeding step pitch of a work-piece and a technological scrap margin of the work-piece in dependence on an automatic feeding technology in the production, the material utilization rate can be increased by about 0.9%-1.9%; by the adoption of a staggering technology and the full utilization of an effective area, the width of the strip material is saved and effective punching sheet productivity is increased by about 6%-13%; and the multicolumn staggered punching process of the electric motor with the solid rotor increases work efficiency of the production process, improves production quality of products, prolongs service life of the mould, lowers production cost and improves production safety guarantee.

Description

technical field [0001] The invention relates to the fields of YSE3 series solid rotor braking motors and YDSE3 series multi-speed solid rotor braking motors. In particular, it relates to a multi-row dislocation stamping process for a solid rotor motor. Background technique [0002] As far as the manufacture of stator and rotor cores of electric motors is concerned, cold-rolled silicon steel sheets adopt the traditional punching process, and there are great technological advantages in terms of material utilization, production rate, by-product utilization, work efficiency, product quality, and product life. problems, resulting in waste of resources and inconvenience and inefficiency in manufacturing and use. [0003] Therefore, the present invention is developed on the basis of mainly solving the above deficiencies in the prior art. Contents of the invention [0004] The technical problem solved by the present invention is to provide a multi-column dislocation punching pro...
