Automatic circle cutting device for insulating plate of transformer

Abstract

The invention discloses an automatic circle cutting device for an insulating plate of a transformer. The automatic circle cutting device structurally comprises a machine box base, a supporting frame,an electric control box, a punching driving device, circle cutting auxiliary mechanisms, a circle cutting blade and a rotary replacing type circle cutting table; the machine box base is of a rectangular structure, the supporting frame is erected above the machine box base and is vertically connected through electric welding, the electric control box is fixed on the front surface of the right portion of the supporting frame, the punching driving device is arranged in the middle of the supporting frame, and the circle cutting auxiliary mechanisms are arranged on the two sides of the rear part ofthe punching driving device. According to the rotary replacing type circle cutting table, the feeding and the discharging are synchronously carried out through the 90-degree intermittent rotation, and meanwhile, the center of the cutting circle center is aligned with the center of the insulating plate under the cooperation of an electromagnetic clamping mechanism, the probability of corner missing during circle cutting is reduced, the utilization rate of the circle cutting is improved, and the insulating plate with cut circle can be put down at a lower height difference, so that the corners of the circular insulating plate are prevented from being bumped to lose the corners, and the edge of the circular insulating plate is ensured to be neat.

Description

technical field [0001] The invention relates to the field of transformer processing, more precisely, an automatic circle cutting device for transformer insulating plates. Background technique [0002] Insulation boards are widely used in the manufacturing process of transformers. According to the actual situation of the placement location, sometimes circular insulation boards are used. The insulation boards require neat edges and high dimensional consistency. But there is following defective in the prior art transformer insulating plate cutting circle device: [0003] The original shape of the transformer insulating board is usually a rectangular structure. To achieve the maximum cutting rate, the center of the cutting circle must be aligned with the center of the rectangular insulating board. It is difficult to use automatic or manual feeding in the prior art. Its accurate alignment leads to missing corners of the insulating board after the round cutting process, or requir...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide an automatic circle cutting device for transformer insulating plates to solve the problems of the prior art transformer insulating plate cutting circle device. Because the original shape of the transformer insulating plate is generally a rectangular structure, it is necessary to realize the maximum To achieve a high degree of circle cutting rate, the center of the circle cutting circle must be aligned with the center of the rectangular insulating board. It is difficult to align accurately with the automatic feeding or manual feeding of the existing technology, resulting in the insulation board after the circle cutting process. There are missing corners, or a larger rectangular insulation board is required, which greatly reduces the defect of the utilization rate of the insulation board cutting circle
