Abstract

The invention relates to a noise reduction device for a transformer iron core shearing machine tool, comprising a front plate, a rear plate, a left plate, a right plate and a cover plate, wherein the front plate, the rear plate, the left plate and the right plate are connected end to end, and the top is connected to the cover plate A box is formed, and sound-absorbing cotton is pasted on each inner side of the box. The size of the box matches the size of the punching device on the transformer core shearing machine, and a first rectangular hole is opened in the middle of the bottom of the front plate and the rear plate. There are second rectangular holes corresponding to the hydraulic pipes on the transformer iron core shearing machine tool respectively on the front plate and the rear plate, and on both sides of the first rectangular hole. The corresponding position of the track is provided with a third rectangular hole. The invention not only can obviously reduce the noise pollution of the transformer iron core shearing machine tool, but also facilitates the replacement of punching cutters.

Description

Technical field [0001] The invention belongs to the technical field of noise reduction of numerical control shears, and particularly relates to a noise reduction device of a shearing machine tool for producing transformer cores. Background technique [0002] The shearing knives of the existing shearing machine tools used to produce transformer cores are all installed on a fixed tool holder, and a punching device is provided at the rear end of the fixed guide frame for punching silicon steel sheets. In the process of silicon steel sheet, the operator needs to organize and remove the cut silicon steel sheet at any time, otherwise it will cause the silicon steel sheet to accumulate and fall on the ground to damage the silicon steel sheet. However, due to the existing shearing machine tools used to produce transformer cores Generally, there is no noise reduction device. When working, the punching sound is above 80 decibels, which seriously affects the hearing of the operator and the ...
