Embodiment 1

[0029] Such as figure 1 A specific embodiment of the material belt structure for commutator processing shown includes several material belt components arranged in sequence. Each of the strip components includes a lap 5 for conveying the strip structure to the next station, a strip body 4 and a first hook 1 for connecting the lap 5 and the strip body 4. Several second hook bodies 2 and third hook bodies 3 are respectively arranged on both sides of the strip body 4 perpendicular to the conveying direction, and the length of the second hook bodies 2 is less than the length of the third hook bodies 3, wherein the first A hook body 1 and a second hook body 2 are formed on the same side of the strip body 4 .

[0030] Several strip assemblies are connected through the line 7 to be cut between the strip bodies, and the setting of the line 7 to be cut is for the convenience of later cutting and separating the strip structure into several independent strip assemblies. The strip assemb...

Embodiment 2

[0039] A specific embodiment of the method for producing a copper shell using a strip structure used for commutator processing includes first cutting the copper strip into a strip structure of the required specification according to the size requirements, and at the same time cutting the copper strip into a strip structure according to a predetermined interval. One side punches and forms several positioning holes 6 . Then set the shape and position of the pre-punching cutting of the stamping and cutting equipment, that is, to remove the excess copper material except the lap 5, the strip body 4, the first hook 1, the second hook 2 and the third hook 3 , to process the strip structure into several strip assemblies arranged in sequence, and simultaneously form the line 7 to be cut between two adjacent strip structures; the edge 5 of each strip assembly passes through the first hook The body 1 is connected to the strip body 4, and several second hook bodies 2 and third hook bodies...

Abstract

The invention relates to the field of commentator copper shells used for motors, and specifically relates to a material strip structure used for commentator processing. The material strip structure comprises a plurality of material strip assemblies arranged in sequence, wherein each material strip assembly comprises a landing edge for transferring the material strip structure to the next station downwards, a material strip body and a first hook body for connecting the landing edge and the material strip body; a plurality of second hook bodies and a plurality of third hook bodies are arranged on two sides, vertical to the transferring direction, of the material strip body, and the lengths of the second hook bodies are smaller than those of the third hook bodies; and the first hook body andthe second hook bodies are formed on the same side of the material strip body. The invention also relates to a method for producing a copper shell by using the material strip structure used for commentator processing. The method comprises the following steps: processing the material strip structure into a plurality of material strip assemblies arranged in sequence; then bending and forming the material strip assemblies into the copper shell; and finally separating the first hook body from the copper shell. According to the material strip structure used for commentator processing and the methodfor producing the copper shell by the material strip structure provided by the invention, materials are stably fed in the processing process, and the quality of the final product is high.

Description

technical field [0001] The invention relates to the field of commutator copper shells for motors, in particular to a material strip structure for commutator processing and a method for producing copper shells using the same. Background technique [0002] The commutator is an important part of the motor. It is mainly composed of a copper shell and an insulating matrix. The function of the commutator is to keep the direction of the output current unchanged. It is widely used in automobiles, office equipment, power tools, aerospace and other fields. As the most important part of the commutator - the copper shell, its processing quality directly affects the quality of the commutator product. Most of the existing copper shells are processed by drawing and punching a single copper sheet, then punching a single mica sheet, and finally positioning it on the plastic core by manual sheet arrangement for subsequent extrusion or injection molding. It can only be operated manually, so t...
