Vulcanite bond cutting wheel

The utility model relates to the abrasive industry, namely, to the design of cutting wheels on a volcanic ligament.

Known cutting wheel on a volcanic ligament made with a landing hole (1).

The disadvantage of this circle is low mechanical strength, low grinding speed, low grinding coefficient. The hardness of the wheels, the assortment (size range) of the cut-off wheels, as well as the assortment of grinding materials (grit) are limited.

It expands the size range of circles and the ranges of graininess of grinding materials, as well as the range of hardness of wheels closest to technical dryness; the dryness and the effect achieved by the proposed cutting wheel on a volcanic bond made with a landing hole (2).

The disadvantage of this circle, as well as the aforementioned analogue, is its low mechanical strength and low grinding coefficient.

The objective of the proposed technical solution is to eliminate these drawbacks, namely increasing the mechanical strength of the circles and increasing the grinding coefficient.

The problem is achieved in that the cutting wheel on a volcanic bond made with a landing hole, according to the proposed solution, contains a reinforcing element at a height of N / 2, WHERE N is the height of the wheel.

The implementation of the volcanic circle with a reinforcing element will increase the strength of the circles, increase the grinding coefficient, which increases the wear resistance and durability of the circles.

Circle 1 is made with a nozzle hole 2. At a height of H / 2, where H is the height of circle 1, a reinforcing element 3 is installed. Circle 1 is provided with a sleeve 4 of the hole 2.

Circle 1 is made as follows.

The prepared molding abrasive mass is subjected to double sequential calendering and subsequent calibration. Annular blanks are cut from the resulting sheet. Ring blanks are folded into a bag, laying them with a pre-cut reinforcing element 3. The bag is placed in a mold with a mandrel, on which sleeve 4 is put on, and pressing is performed. The compressed bag is then vulcanized and machined.

According to the proposed solution, cutting wheels on a volcanic binder with dimensions of 230x3.2x22 mm were made. A fiberglass mesh was used as a reinforcing element.

The experimental batch of cutting wheels passed industrial tests, as a result of which it was found that the strength of the obtained wheels increased almost 1.5 times, and the grinding coefficient increased 2 times.

The proposed technical solution will find application in the abrasive industry in the in-line production of cut-offs from circles on a volcanic bond used in the engineering industry for cutting workpieces mainly from structural steels.
