Description

one

The invention relates to stands for testing impact devices of trans-construction.

A stand for testing deforming devices is known, containing a sleeve for placing a deforming device in it with the possibility of axial movement, a loading cylinder acting on it, as well as a support mounted on the frame with an acute angle to the axis of the loading cylinder with a power iodor, deforming devices.

The purpose of the invention is to recreate the actual loading conditions of the deforming devices and, mainly, of the hammer.

For this, the support is made in the form of a rotary anvil, H1 marzirno fixed at one end of the para frame, and between the anvil and the frame is a spring.

The drawing shows the scheme of the proposed stand.

The deforming device, pneumatic hammer 1, is installed in sleeve 2, which moves along guide rails 5 using a loading hydraulic cylinder 4. A pneumatic hammer's tooth abuts against a sprung anvil 5. When the frame 6 is installed, the iodine angle different from 90 ° to the pneumatic hammer axis - The springs 7 are decomposed into two components. For

2

the excavator digging cycle is controlled by a hydraulic cylinder by a reversible electro-hydraulic slide 8, and a certain rate of increase in load and unloading of the pneumatic hammer is controlled by thrusting the fluid to the hydraulic cylinder drain with chokes 9,} with a regulator and a reverse claian.

The stand works as follows.

The oil is supplied through the gold mat, which is included in the position of the valve, the throttle check valve in the rear cavity of the hydraulic cylinder, and the oil from the middle bottom is drained through the choke and the oil tank. In this case, the hydraulic cylinder moves the shaft with a pneumatic hammer installed in it forward. Pneumatic hammer tooth is pressed into the spring anvil and compresses the elastic elements. When a certain force is reached on the tooth, the machine starts, and the hammer starts working, striking the sprung anvil.

The cylinder moves the pneumatic hammer forward until the pressing force reaches a predetermined value. After that, the spool switches to the "Locked. After a certain time has elapsed, the spool is transferred to the position “Pazad, and the hydrocyliidr moves the pneumatic hammer back. Upon reaching the effort

pressure of zero, the gold is again transferred to the "Forward, and the cycle repeats.

Subject invention

A stand for deformation device inventions, containing a sleeve for accommodating a deforming device with axial movement and a loading cylinder acting on it, as well as a support with force bearing mounted on the frame at an acute angle to the axis of the loading cylinder, which receives the load from the deforming device that differs the fact that, in order to recreate the actual loading conditions of the deforming devices, mainly pneumatic hammers, the support is made in the form of a rotary anvil, Attached at one end on the frame, and between the anvil and the frame is a spring.
