Abstract

Usage: in devices using, impact force. Essence: cutting S element 9 with turbine 8 is rotationally driven from compressed air through a fitting with a check valve 15. When compressed air is supplied to the fitting 18, the multiplier piston 13 will compress the compressed air in the chamber 26 and this pressure will flow to the turbine 8 and under the piston which starts moving up and sharply turns the flywheel (5 and 6) through an angle of 180 °, and then the flywheel (5 and 6), under the action of inertia and centrifugal forces, enters the cutting zone with high speed and immediately the flywheel (5 and 6) starts braking with balls oh adjustable brake. 2 ill.

Description

The invention relates to the field of mechanical engineering, in particular to devices used in metal forming using impact force.

The aim of the invention is to simplify the design, increase reliability and durability.

In FIG. 1 is a general view of the device in section AA in FIG. 2; in FIG. 2 section BB in FIG. 1.

. The pulsed cutting device consists of a housing 1 and a cover 2, inside of which a flywheel 5 and 6 are mounted on bearings 3 and 4. In the flywheel 5 and 6, a turbine 8 of two halves is installed on the bearings 7, between which a cutting element 9 is fixed.

A sleeve 10 is mounted in the central part of the flywheel 5 and 6. A multiplier 12 is fixed to the housing 1 with bolts 11, in which there is a twin piston 13 (see Fig. 1). A piston 14 is installed in the flywheel 5 and 6 (see, FIG. 2). A fitting with a non-return valve 15 is installed in the pneumatic cylinder 12, a fitting 16, a fitting 18 is installed in the cover 17 (see Fig. 1). In the housing 1 and the cover 2 there are installed spring-loaded ball brakes 19, which are in contact with the smooth protrusions 20 mounted on the ends of the flywheel 5 and b. A fixed cutting element 21 is installed in the housing 1 and the cover 2. In the sleeve 10 there is an opening 22 and an annular groove 23, from which two channels 24 go to the turbi 8 and an adjustable channel

25 under the piston 14 (see. Fig. 1, 2),

The device operates as follows,.

Through a fitting with a check valve 15, compressed air (P 5 atm) enters the chamber

26 and through the sleeve 10, the hole 22, the annular groove 23 and through the two holes 24 to the turbine blade 8 with the cutting element 9, which starts to rotate, compressed air (P 5 atm) will come under the piston 14, but this is not enough , Th. With, n began to rise PG: Snl. compressed air (P 5 atm) enters through the nozzle 18, as a result, the twin piston 13 starts to move, the nozzle with the check valve 15 closes and the chamber 26 increases the pressure to 50 atm, which will flow to the turbine 8 and under the piston 14, as a result the turbine 8 will increase its rotational speed, and the piston 14 will go up sharply and turn the flywheel 5 and 6 to turn sharply through an angle of 180, and under the influence of inertia and centrifugal forces the flywheel 5 and 6 will pass the cutting zone at high speed, and the compressed air (P 5 atm) will go through the fitting 16 and move

dual piston 13 to its original position. Flywheel 5 and 6 at an angle of 350 ° will begin braking, i.e. the planned protrusions 20 will be run in by a ball spring-loaded brake 19. Compressed air (P 5 atm.) through the fitting with a check valve 15 will again flow into the cavity 26 and into the turbines 8.

The cycle is over.

The design of the device allows cutting of any material (steel, wood, plastic, glass and other materials), and a power shock and vortex cutting occur. The cutting element is not kinematically rigidly connected to the drive and, upon meeting with a workpiece of increased strength, is able to return to its original position. A pulsed cutting device has a number of advantages over its analogues and prototype. When cutting the material, four speeds are folded:

Vi - rotation of the turbine 7 from P 5 ATM. / 2 - rotation of the turbine 7 from P - 50 atm. Uz - rotation of the flywheel 5 and 6 from the impact of the desired piston 14.

/ 4 - additional rotation of the flywheel 5 and 6 inertia forces and centrifugal forces. Advantages of the device: Ease of manufacture, adjustment and maintenance, high 5 degree of reliability and durability, high productivity due to high cutting speed, noise and vibration eliminated, wide versatility, that is, work without readjustment, manual pipe exceptions and more.

Technical and economic indicators: 1. The cutting speed compared to existing cutting machines is increased 100-150 times.

2 .. Performance. quality, accuracy will increase several times.

3. The resistance of the cutting element. Grows many times

th io feels the need for electricity, expensive appliances, material, etc.

5. A small footprint is required for installation.
