Cutting device for production of transformer

Abstract

The invention discloses a cutting device for the production of a transformer. The cutting device comprises a bottom plate; supporting blocks are fixedly mounted on both sides of the lower end of the bottom plate, and square blocks are arranged on both sides of the upper end of the bottom plate; a square hole is formed in the lower side of each square block, an insulating cardboard penetrates through the square holes, sliding holes are formed in the front and back portions of the upper side of the interior of each square hole, and a sliding column is slidably mounted in each sliding hole; the lower end of each sliding column is fixedly connected with a propping plate; an inserting rod is inserted into an inserting groove, a sliding-preventing surface is propped against and is in contact with the insulating cardboard, the combining resistance between a rubber plate and the insulating cardboard is increased, and the insulating cardboard is limited to bounce during cutting, so that the position for fixing the insulating cardboard is more convenient; and when a cutting knife cuts off the insulating cardboard, paper scraps enter into a cutting knife groove and further drop into a squarebox through a feeding groove, the square box can be pulled out of a storing groove, the paper scraps in the square box can be poured into the garbage can, and the paper scraps can be effectively prevented from accumulating in the cutting knife groove.

Description

technical field [0001] The invention relates to the technical field of transformer production, in particular to a cutting device for transformer production. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. [0003] Transformer insulating cardboard is widely used in the assembly of transformers. In the actual production process, it is necessary to cut long insulating cardboards of uniform width into different lengths. Tighten the insulating cardboard, so that the insulating cardboard will not jump when cutting. After cutting, the bolts need to be rotated to loosen, and one pressing plate needs to be locked with two or more bolts, which makes the insulating cardboard fixed. The location is very complicated, and at the same time, after the cutter cuts the insulating cardboard for a long time, the cut paper dust will accumulate at t...
