Shaving injury preventing shaving device for automobile tire and method thereof

Abstract

The invention discloses a shaving injury preventing shaving device for an automobile tire and a method thereof. The shaving injury preventing shaving device comprises a U-shaped tool rest, a shaving blade and ashaving injury preventing component; the U-shaped tool rest comprises a left vertical rod, a right vertical rod and a cross rod, springs and fixing sleeving rings successively sleeve the left vertical rod and the right vertical rod from bottom to top correspondingly, and second thread holes are formed in the fixing sleeving rings; V-shaped grooves are formed in the upper surface of the cutting edge end of the shaving blade, an inclined face is arranged on the lower surface of the cutting edge end of the shaving blade, triangular cutter teeth are formed at the intersections of the inclined face and the V-shaped grooves, and first fixing holes matched with first thread holes are formed in the shaving blade; the shaving injury preventing component comprises a rectangular body and aplurality of rectangular top strips, second fixing holes matched with the second thread holes are formed in the two ends of the rectangular body, the bottom ends of the rectangular top strips are connected with the side face of the rectangular body, and V-shaped grooves are formed in the top ends of the rectangular top strips; the shaving injury preventing component is fixedly installed on the fixing sleeving rings; and the top ends of the triangular cutter teeth are arranged opposite to the top ends of the rectangular top strips, and inserted into the V-shaped grooves in the top ends of the rectangular top strips.

Description

technical field [0001] The invention belongs to the field of automobile tire production, and in particular relates to an automobile tire anti-shaving shaving device and a method thereof. Background technique [0002] Automobile tires are rubber products. The molded tires need to be vulcanized under high temperature and high pressure in the mold. During the vulcanization process, in order to increase the fluidity of the rubber and make the rubber evenly distributed, it is necessary to open pores on the surface of the mold. Therefore, the tire after vulcanization The surface is covered with hairs with a diameter of about 1-2mm and a length of about 10-15mm. Before the finished tire leaves the factory, the hairs on the surface of the tire need to be removed, commonly known as shaving. [0003] The traditional shaving device has a simple structure and is widely used. The traditional shaving device can be used by fixing the blade on the knife holder. The blade of the blade is com...

AI Technical Summary

Problems solved by technology

Because the tip of the triangular tooth on the blade is extremely sharp, and there are uneven patterns on the tread of the tire, and there is unstable vibration when the tire rotates at high speed during the shaving process, the tip of the triangular tooth is easy to shave. Scratches and scratches the tread, which affects the quality of the tire, especially at the intersection of the concave part of the tire surface pattern and the tread, the tip of the triangular knife tooth is easy to penetrate, which seriously leads to the scrapping of the tire and the reduction of the tire yield
