Self-adhesive sticker rapid blanking process

Abstract

The invention relates to a self-adhesive sticker rapid blanking process, and belongs to the technical field of transformer production. The technical scheme is that a blanking hammer is used for manufacturing self-adhesive stickers and is composed of punch (1) installed on a handle (2). The punch is in a hollow structure, and the end portion is provided with a closed cutting edge. A self -adhesive paper (4) is placed on a rubber mat (5), hammered by the blanking hammer and cut by the sealed cutting edge of the end portion of the punch to be manufactured into a self-adhesive sticker with a shape in accordance with that of the closed cutting edge of the end portion of the punch. Shapes and sizes of closed cutting edges of punches are variant, self-adhesive stickers with different shapes and sizes are matched with the closed cutting edges of the punches with different shapes and sizes, only different punches are needed to be changed, and then different self-adhesive stickers can be manufactured. The self-adhesive sticker rapid blanking process has the advantages that the operation is simple and convenient, the blanking speed is fast, and the shaping is regular. Besides, the punches have multiple specifications and can be changed at any time, so that the operation program is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to a fast-blanking process for self-adhesive patches, which belongs to the technical field of transformer production. Background technique [0002] The iron core parts inside the transformer need to be reliably grounded. Therefore, the threaded holes and light holes of parts such as clamps, pull straps, pull plates, and feet of the iron core parts cannot be painted. These parts need to be cut into circles before painting. self-adhesive stickers for protection. At present, the method of cutting the self-adhesive patch in the background technology into a circle is to place the circular block on the self-adhesive paper, and use a knife to draw a circle along the outer edge of the circular block. However, the same component often includes more than 5 round holes of different specifications, and the number is also large. Using the cutting method of the background technology, there are problems such as slow cutting speed, irregular dia...

Problems solved by technology

However, the same component often includes more than 5 round holes of different specifications, and the number is also large. Using the cutting method of the background technology, there are problems such as slow cutting speed, irregular diameter of the wafer, poor molding quality, and affecting the protective effect. question

For the circular forming of self-adhesive paper, it is generally easier to use punching or blanking molds, but for production costs, the cost of processing costs will increase a lot, and the utilization rate of molds is low, resulting in high production costs
