High-strength light high-toughness burr-free luminous punch with sterilization function

Abstract

The invention discloses a high-strength light high-toughness burr-free luminous punch with a sterilization function. A screw penetrates through the rear end of a blade and the parts, located on the two sides of a groove, of the punch base. Moreover, the part, penetrating out of the punch base, of the screw is locked and fixed by nuts. A cutting edge is arranged at one end of the blade and formed by laminating and pressing a plurality of steel discs. The two ends of the cutting edge are machined to be fillets. Two joining pieces are welded to the punch base. The free end of each joining piece is provided with a hook, two slots are formed in the rear end of the blade, and the hooks of the joining pieces can stretch into the corresponding grooves of the blade to be connected with the blade in a matched mode. A light source is arranged on the punch base and generates ultraviolet light. A plurality of light guide pieces are arranged on the blade and located on the edge of the cutting edge. The light guide pieces are perpendicular to the cutting edge and absorb light emitted by the light source and guide the light to the cutting edge. A plurality of weight reducing grooves are formed in the middle portion of the blade.

Description

technical field [0001] The invention relates to a punch, in particular to a high-strength, light-weight, high-toughness, high-burr-free, sterilizing and luminescent punch. Background technique [0002] The punch seat and the blade of the current punch are integrally formed. After the blade is used for a long time, it is gradually consumed due to wear and tear. Finally, the blade cannot be used because it is damaged and scrapped. Since the blade and the punch seat cannot be separated, the whole punch is also If it is scrapped, the punch needs to be replaced again, which greatly increases the cost of use and increases the burden on the enterprise. Simultaneously, because the current blade is integrally formed, this just causes the overall strength of the blade to be lower, and the toughness is poor, and the blade is easily broken, causing damage to the cutter. In addition, the current punch stamping products are easy to form burrs on the fracture surface of the product, which...

Problems solved by technology

[0002] The punch seat and the blade of the current punch are integrally formed. After the blade is used for a long time, it is gradually consumed due to wear and tear. Finally, the blade cannot be used because it is damaged and scrapped. Since the blade and the punch seat cannot be separated, the whole punch is also If it is scrapped, the punch needs to be replaced again, which greatly increases the cost of use and increases the burden on the enterprise

At the same time, since the blade is formed as a whole, the overall strength of the blade is low, the toughness is poor, and the blade is easy to break, resulting in damage to the blade.

In addition, the current punch stamping products are easy to form burrs on the fracture surface of the product, which reduces the quality of the product and cannot meet the requirements of some product finishing.

At the same time, the overall quality of the current blade is relatively large, which affects the use of the punch, and is made of stainless steel, and the cost is also relatively high

In addition, the bonding strength between the blade and the punch seat is not enough, which often easily causes damage to the blade and brings great losses to the enterprise.

At the same time, at present, bacteria are quite easy to remain on the knives, causing the hygienic quality of the knives to be considered, which will also have an adverse effect on the production and processing of the aseptic workshop, and the current knives cannot emit light, so when the light is dark, the operator cannot It is better to use knives, and there are certain safety hazards, which have a greater impact on the operation
