Noise lowering device of transformer iron core shearing machine tool

Abstract

The invention relates to a noise lowering device of a transformer iron core shearing machine tool. The noise lowering device comprises a front plate, a rear plate, a left plate, a right plate and a cover plate. The front plate, the rear plate, the left plate and the right plate are connected in an end-to-end manner, the top is connected with the cover plate, and then a box body is formed. Sound absorbing cotton is bonded to the inner side faces of the box body. The box body is matched with a punching device on the transformer iron core shearing machine tool in size. A first rectangular hole is formed in the middle positions of the bottoms of the front plate and the rear plate, and second rectangular holes corresponding to a hydraulic pipeline on the transformer iron core shearing machine tool are formed in the front plate and the rear plate and in the two sides of the first rectangular hole. The positions, corresponding to a track on the transformer iron core shearing machine tool, of the bottoms of the left plate and the right plate are provided with third rectangular holes. By means of the noise lowering device, noise pollution of the transformer iron core shearing machine tool can be obviously reduced, and punching tool replacing is convenient.

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 ...
