Description

one

The invention relates to mechanical engineering and can be used in the design of forging and stamping equipment.

The purpose of the invention is to increase the reliability of the hammer due to the removal of vibration loads from the fasteners of the hydraulic communication unit.

The drawing shows the design of the hammer.

A vertical steam-free air hammer contains a frame 1, a working cylinder 2, an upper woman 3, a lower woman 4, which are connected between a hydraulic system consisting of an average cylinder 5 and side cylinders 6, which are located in the housing of a hydraulic communication unit 7 and are connected by channels 8, lateral plungers 9 mounted on the shock absorber top 10 of the hammer. 10. The base of the hammer and the housing of the hydraulic communication unit rest on the foundation 11. A vibroisolator 12 is installed between the supporting surfaces of the housing 7 and the foundation 11, The guides of the flex tank are mounted guides 13.

Hammer works as follows.

At the inlet of the energy carrier into the upper cavity of the cylinder 2, the upper woman 3 and the lateral plunger L. Avramenko 580/14 associated with it are

The fish 9 moves down. The pressure that the side plungers 9 create in the side cylinders 6 displaces the working fluid into the middle cylinder

5 5, as a result of which the bottom 4 is moved upwards before impacting with the top 3,

When the upper woman 3 moves down and the lower woman 4 up in the housing 7,

10 in addition to the initial static pressure, there is an additional pressure due to the inertia force of the lower woman 4, after the impact of the upper and lower women lower woman 4

15 and for some time the side plungers 9 by inertia move downwards, simultaneously compressing the fluid in the housing 7 and increasing its pressure. Then the side plungers 9 move upwards, 20 and the pressure in the housing 7 decreases. This change in pressure occurs in very small periods of time, i.e. dynamically and causes mechanical vibrations of the hull

25 hydraulic communication assemblies, which are perceived by vibration isolator 12, and oscillating movement of the hydraulic communication body is performed in guides 13 fixed on frame 1.

30 The economic effect of implementing the invention is achieved by increasing the reliability of a smooth vertical steam hammer.
