Description

one

The invention relates to the field of machine tools, in particular to copiers.

Hydraulic copiers are known, made in the form of a copier, cylinders of the copier and driver movements, the follow-up spool and automatic regulator.

However, such devices do not provide the constancy of the total supply,

With the elimination of this deficiency, the autoregulator of the proposed device is installed; It is located on the highway going from the next slide valve to the cylinder of copying movement, in which the second autoregulator and damper are additionally installed.

The drawing shows the described device.

The hydraulic copying device consists of a copying device with a barely running slide valve 1 and a spring 2, a cylinder of copying movement 3, a cylinder of driving movement 4, a damper 5, two autoregulators with stepped plungers 8 and springs 7,

The plungers form chambers 8 and 9. The control spool 10 is installed for reversing the direction of the driver feed. The speed of the copy and driver feeds is controlled by throttles 11 and 12.

When turned on, the oil from the pump enters the spool 1, which is in the upper position under the action of the spring 2 / together with the discharge line of the pump with the rodless cavity of the copy cylinder 3. At the same time, the maolo through the spool 10 enters the shaft of the cylinder defining movement 4. In In the case when the profile of the copier is perpendicular to the axis of the driver's movement, the oil entering the rodless cavity of the cylinder of the copying movement passes through the damper 5, and before and after the pressure damper there will be different s, i.e. one of the plungers 6 will be in the upper position, and the other in the lower one will also have oil from the drain cavity of the setting cylinder 11) {) and o will flow, in connection with which there will be only one transverse flow.
