Slot wedge one-time forming device

Abstract

The invention provides a slot wedge one-time forming device. The slot wedge one-time forming device comprises a polishing device, a milling device, a conveying device and a pressing holder. The conveying device comprises a plurality of pairs of paired rollers and a guide rail which are arranged on a conveying path of a slot wedge strip. The paired rollers include driving rollers and driven rollers, wherein the driven rollers are arranged above the driving rollers. The milling device comprises two milling machines arranged on the two sides of the conveying device respectively, and it is guaranteed that the two milling machines are staggered. Each milling machine comprises a base, an arc-shaped support and a third milling cutter. The pressing holder is used for clamping the slot wedge strip at the conveyed state. The slot wedge one-time forming device has the advantages that the automation degree is high, deviation of the slot wedge strip in the conveying process and sparks produced in the machining process are prevented, safety is improved, and timeliness of scrap cleaning is improved.

Description

technical field [0001] The invention relates to a processing device, in particular to a slot wedge forming processing device at one time. Background technique [0002] As we all know, for medium and large AC high-voltage motors, due to the special requirements of insulation and manufacturing process, the stator winding adopts formed coils, and the stator core is made of open or semi-open slots. Using a magnetic slot wedge to close the stator notch of this type of motor can also achieve energy saving effects while sending it to the fixed coil. [0003] Slot wedges are mostly made of polyester resin, glass fiber and reduced iron powder as raw materials, and have certain mechanical strength and relative magnetic permeability. [0004] The traditional slot wedge processing technology has the following deficiencies: (1) manual processing or semi-automatic processing is used, and the degree of processing automation is low; (2) when the slot wedge is in a long-term conveying state...

AI Technical Summary

Problems solved by technology

[0004] The traditional slot wedge processing technology has the following deficiencies: (1) manual processing or semi-automatic processing is used, and the degree of processing automation is low; (2) when the slot wedge is in a long-term conveying state, on the one hand, the gap between the slot wedge and the transmission device There will be relative sliding between them; on the other hand, due to the vibration of the machine, the movement of the slot wedge will be offset, which will affect the conveying efficiency of the slot wedge and bring troubles to subsequent processing; (3) use the grinding wheel to grind the slot wedge Processing is easy to generate sparks; (4) After the processing is completed, the waste removal work is carried out, and the timeliness of impurity removal is low
