Description

the hydraulic cylinder 10, the rod of which is associated with the prism 11 by means of a rolling pin 12.

The operating cycle of the clamping mechanism 9 is controlled by a contact device comprising petals 13 and 14 fixed on the rolling pin 15, rigidly connected to the rolling pin 12 of the prism 11, and the end switches 16 and G / fixed by means of the bracket 18 on the spindle head 4.

The spindle head 4 contains an actuator of the main movement 19 with a gearshift mechanism 20, a quill 21 with a spindle 22 and a cutting head 23.

The hydraulic cylinder 24 serves to communicate the quill feed movement 21.

The operation of the quill cycle is made by a contact device containing a rod probe 25, passing through the hollow rod 26 of the cylinder 24 and the hollow spindle 22 of the inioli 21, the rod 27 with lobes 28 and 29 and the end / switches 30, 31 and 32, mounted on the yoke 33 rigidly connected to the hollow rod 26. The rods 25 and 27 are provided with bevelled T-shaped heads. The rod 27 is guided in the bores of the body of the headstock 4.

The spring 34 serves to force the probe 25 against the spindle 22.

Petal 35. rigidly fixed on the headstock 4 and interacts with the limit switch 32 in the initial position of the quill 21.

For readjustment of the contact control device for the quill cycle, there is an automatic readjustment mechanism comprising a copier 36 with T-shaped angled slots and two rolling pins 37 guided by bores in a bracket 38 rigidly mounted on a rack 2.

The angle of the T-slot is determined from the dependence

sln, where p is the angle of inclination of the T-shaped groove of Conir; F - the angle of the machined chamfer

to the axis of hire (spindle); and - the angle of the prismatic recess of a fixed prism. .

The spring 39 constantly presses the copier 36 to the rod - probe 25.

The extreme upper and lower positions of the spindle head 4 are controlled by end switches 40 and 41 fixed on the clamping mechanism 9 and a tab 42 fixed on the bracket 18 of the spindle head 4.

The gearbox 5 has a circular contact transducer 43, which serves to automatically control the movement of the spindle head 4 vertically during the changeover of the machine to the processing of another rolled diameter. The machine works as follows.

With the grips of the rolling mill transnorth device, the end of the rolled steel is placed in a prism 8. A command is issued to turn on the machine. The quill is in its initial position at this time.

Connected by means of a rolling pin 12 with a rod of a hydraulic cylinder 10 a prism AND a clamping mechanism 9, moving down, clamps the hire.

In this case, the petal 14 enters the end switch 17 and gives the command to turn on the drive of the main movement 19 and the hydraulic cylinder 24 of the supply of quill 21 — a quick supply of the quill to the end of the hire is carried out.

Together with the quill 21, the spindle 22, the tool head 23 and the probe 25 move.

Moving the bar - probe 25 by means of a T-shaped connection with the horse 36, moves it and the bar 27 with petals 28 and 29 in the direction of the movement of the ninoli 21. The bar - probe 25 stops at the end of the rolled 6. Along with it stop the copier 36 and the rod 27 with petals 28 and 29.

Continuously moving the quill 21 moves the yoke 33 with the end switches 30 and 31.

When the end switch 30 comes into contact with the tab 29, a command is issued to the working feed. Starts rolling processing.

At the end of the working stroke, the end switch 31 comes into contact with the tab 28, a command is received to quickly retract the quill 21 to the initial position, in which the limit switch 32 attached to the cross bar 33 comes into contact with the tab 35 (Fig. 3) and gives the command to retract Prism 11 clamping mechanism 9 to its original position. A rolling pin 15 with lobes 13 and 14 is moving together with the prism AND. Petal 13 comes into contact with the end switch 16 — the command is given to stop the prism 11 of the clamping mechanism 9 and activate the movement mechanism of the gripper of the rolling machine transport device.

The cycle of the machine is repeated.

When switching to the processing of a different diameter of rolled metal from the central control station of the rolling mill, a command is issued to turn on a circular contact converter 43, which gives a pulse to turn on the electric motor of the gearbox 5, monitors the movement of the spindle head 4 and stops it in a position corresponding to the coincidence of the axes of the cutting head 23 and specified diameter rolled.

During the movement of the spindle head 4 along the column guides 2, the rods 25 and 27, moving together with the headstock 4, slide their Imaginary heads along the notch of the fixed in the vertical plane 36.

When this occurs, the automatic changeover of the contact device for controlling the work of the quill is performed, as follows. Rod-probe 25, pressed by the spring 34 to the spindle 22, remaining fixed in the horizontal plane and slipping along the SoMy slope of the copier 36, moves it along with the rod 27 in the horizontal plane. In addition, the rod 27, slid along the inclined groove of the copier 36, additionally moves in a horizontal plane. When the rod 27 moves in a horizontal plane, rigidly attached 10 petals 2b and 2U move along with it. The end switches 30 and 31, which are in contact with them, remain stationary, the keys - and - n - ak as the yoke 33, on which they are fixed as the yoke 33, on which they are fixed, with the vertical movement of the headstock 4 15, "", "", GOTOLOLDAT1TRNII PaOKI H is in the starting position. Thus, as a result of the horizontal movement of the rod 27 along the gauge 36 when the spindle babVERTIK .a is vertically moved. I "ipish in.p, ... x, v ----- .." ,,, Thurs, oni 4 and horizontal the movement itself 20, „„ „,, i, .. when the copier 36 itself is acting under the influence of a stationary horizontal direction at the time of readjustment of the probe 25, the petals 29 and 28 are set to the position corresponding to the values of the quill moves required for the treatment of 2 given diameter of rolled products. Simultaneously with the automatic changeover of the contact device for the control of the work of the quill, automatic change occurs.
