RU1805038C - Device for cutting nonmetal material - Google Patents

Abstract

Usage: processing of non-metallic materials by pressure, cutting blanks into parts. SUMMARY OF THE INVENTION: The drive shaft 1 drives the blade of the blade 2. The guard 5 covers the blade 2 and is located above the drive shaft 1 from the side opposite to the workpiece. Under the casing, opposite to one another, on both sides of the disk are two blocks of the cooling unit 3. The node 4 for supplying water-abrasive suspension, also of two blocks, is located behind the cooling unit in the direction of rotation of the disk knife 2. 3 ill.

The invention relates to a technique for processing materials by cutting and can be used for high-quality processing of non-metallic materials.

The purpose of the invention is to expand technological capabilities and increase productivity.

Figure 1 shows the device, a General view; figure 2 is the same, bottom view; figure 3 - section aa in figure 1,

The device comprises a drive shaft 1 on which a disk knife 2 is mounted, a cooling unit 3, a water-abrasive suspension supply unit 4 and a protective casing 5. The cooling unit 3 and a water-abrasive suspension supply unit 4 are made in the form of a pair of blocks located opposite one another on different sides of the disk knife 2, The protective casing 5 on its sides covers part of the disk knife 2 and completely the cooling units 3 and the water-abrasive slurry supply 4 and is mounted above the drive shaft 1 from the side opposite to the workpiece, and the feed unit and the water-abrasive slurry 4 is located at a certain distance behind the cooling unit 3 in the direction of rotation of the disk knife 2. During operation of the device, a cutting edge 6 is formed.

The device operates as follows.

A rotating drive shaft 1 drives the rotary blade 2, which, passing through the cooling unit 3, is cooled to. negative temperatures, due to the rotation of the circular knife 2 of his

the cooled section enters the field of action of the water-abrasive slurry supply unit 4, from there a water-abrasive slurry enters the surface of the disk knife 2. Wherein

a cutting edge 6 is formed by which the cutting process is carried out directly.

The location of the nodes 3 and 4 and the protective casing 5 above the axis of rotation of the disk knife 2 makes it possible to use almost the entire diameter of the disk knife 2 for processing the product, which also helps to expand the functionality of the device.
