Stacked motor silicon steel sheet stamping device

Abstract

The invention discloses a stacked motor silicon steel sheet stamping device. The stamping device comprises a fixing frame, a workbench is fixedly installed at the lower end of the fixing frame, a power frame is fixedly installed at the upper end of the fixing frame, and a lifting frame is movably installed at the middle position of the fixing frame. The lifting frame comprises a lifting frame body, a current processor, a first gas storage bottle, a second gas storage bottle and an upper mold, the first gas storage bottle and the second gas storage bottle are fixedly installed at the upper end in the lifting frame body, and the first gas storage bottle communicates with the second gas storage bottle through a pipeline. Stamping force generated by the stamping device is converted into power of a pressing plate so that the device can synchronously achieve the flattening function in the silicon steel sheet stamping process, meanwhile, the stamping force generated by the stamping device is converted into current magnitude capable of being monitored in real time through a converter, and then a worker can conveniently monitor and control the stamping force of the stamping device in the stamping process in real time.

Description

technical field [0001] The invention relates to the technical field of silicon steel sheet punching, in particular to a superimposed motor silicon steel sheet punching device. Background technique [0002] Silicon steel sheet is a common name for silicon steel sheet. It has excellent electromagnetic properties and is an important part of the manufacture of motor cores. In the process, the parent roll of silicon steel sheet is usually placed on the stamping line, and then the parent roll of silicon steel sheet is stamped into silicon steel sheets of various shapes by the stamping device, and finally the stamped silicon steel sheets are stacked and assembled into a In this way, the hysteresis loss and eddy current loss of the motor core can be effectively reduced. [0003] In the existing technology, due to the thin thickness of the silicon steel sheet, and for the convenience of transportation and storage, the silicon steel sheet mother roll is usually curled, and in order t...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, due to the thin thickness of the silicon steel sheet, and for the convenience of transportation and storage, the silicon steel sheet mother roll is usually curled, and in order to ensure that the silicon steel sheet can be stacked together, the stamping is completed. Silicon steel sheets must have a certain flatness, otherwise it will affect the subsequent stacking process. On the market, silicon steel sheet flattening devices have begun to appear, such as "CN201621243858.1 A silicon steel sheet pressing device", but this The device needs to complete the stamping of the silicon steel sheet before it can realize the flattening process. The improvement of the production efficiency of the silicon steel sheet is limited. Even if it is mentioned in some patents, the flattening process can be realized through the cooperation of the pressing plate and the upper module, such as "CN201921711371 .5 A Stamping Die for Silicon Steel Sheets discloses the basic structure of the stamping die for silicon steel sheets. Silicon steel sheets are processed through different processing chambers. When the last processing cavity is reached, the upper module descends, and the purpose of flattening the silicon steel sheet is achieved through the flattening block and the upper module, but the working principle of the device is still too simple, and the operation steps are too complicated, so that the silicon steel sheet cannot be effectively improved. Productivity

[0004] In addition, the current silicon steel sheet stamping device usually cannot automatically adjust the punching force during the working process. When the punching force is too large, on the one hand, it will easily affect the quality of the silicon steel sheet, and on the other hand, it will also affect the work of the stamping device. At the same time, in order to ensure that the silicon steel sheet can cooperate well in the stacking process, it is necessary to conduct a test on the stamped silicon steel sheet, so as to prevent the size of the silicon steel sheet from being unqualified, so as to affect the subsequent stacking assembly
