Problems solved by technology

[0003] 1. Low utilization rate of materials
Since electrical steel sheets are generally in the form of cylindrical steel coils, the steel coils are first cut into rectangular steel sheets during processing, and then circular punches are punched out on the steel sheet. This production method will inevitably lead to low material utilization.

[0021] Example 1

[0022] like image 3 As shown in the figure, the present invention is a manufacturing method of a disc motor stator core. The method adopts a punching and winding machine tool specially designed for this type of core, and is processed into an electrical steel coil of a certain width and installed on the unwinding reel 3. , the unwinding reel 3 feeds the electrical steel coil to the feeding table 4 regularly, and the electrical steel coil after passing through the feeding table is punched out of the groove shape through the stamping die 5, and the electrical steel coil after the groove is punched. Winding, winding into the iron core disc 8, the alignment of the grooves on the iron core disc 8 is ensured by the guide ruler 6, and the guide ruler 6 also provides the power to move the fuselage 10 down along the guide rail as the radius of the iron core disc 8 increases, The air cylinder 12 is used to balance the gravity of the fuselage 10. The welding machine 7...

Abstract

The invention relates to a method for manufacturing a disk type motor stator core. The method comprises the following steps that: strip electrical steel is processed into an electrical steel coil strip with certain width; the electrical steel coil strip is arranged on a strip placing disk of a slotting and winding machine tool; the strip placing disk feeds the electrical steel coil strip into a feeding table regularly; the feeding table feeds the electrical steel coil strip into a punching die to punch a slot shape; the electrical steel coil strip punched with the slot shape is wound into a core disk on a wining disk; and the machined core disk is disassembled from the winding disk, then leveled on a tooling table, and welded with a footing to finish the production of a product. Compared with the prior art, the method has the advantages of high material utilization rate, simple equipment and small occupied area.

Description

technical field [0001] The invention relates to a stator iron core of a motor, in particular to a manufacturing method of a disc type motor stator iron core. Background technique [0002] The stator iron core of the traditional motor is formed by punching circular punching pieces on the electrical steel plate, and then superimposing the punching pieces. This kind of iron core has the following shortcomings: [0003] 1. The material utilization rate is low. Since electrical steel sheets are generally in the form of cylindrical steel coils, the steel coils are first cut into rectangular steel sheets during processing, and then circular punched sheets are punched out of the steel sheets. This production method will inevitably lead to low material utilization. Taking a 200mm×640mm electrical steel plate punched with an outer diameter of 100 as an example (the stator and rotor punches are punched out at the same time), the material utilization rate is only about 65%; [0004] 2...
