Description

The invention relates to the field of machine tool engineering and can be used in machine-building and metallurgical enterprises and in other sectors of the national economy for cutting, workpieces, for example, with an abrasive or friction wheel.

The aim of the invention is to expand technological capabilities by increasing the size range of cut parts and increasing productivity.

In FIG. 1 is a plan view of a device for cutting workpieces; in Fig.2 - section AA in Fig.1 (operating, position); on the. figs - section aa in figure 1 (the time of unloading); figure 4 is a section bB in figure 2.

The device for cutting the workpiece 1 comprises a tool head 2 having a cutting tool 3, equipped with a rotary and feed drive, an abutment 4 mounted for movement along a support device 5 made in the form of a roller table, rollers 6 of which are mounted on the frame 7. The longitudinal axis of the support

devices 5 perpendicular to the plane of the cutting tool 3. The device includes clamping devices 8 located on both sides of the cutting tool 3 and each of which is equipped with a drive (not shown).

On the. 7. An additional support device is mounted, which includes an additional frame 9 connected to the frame 7 pivotally through axes 10 lying in a plane perpendicular to the longitudinal axis of the support device 5. The additional support device is equipped with an actuator 11 made in the form of a pneumatic or hydraulic cylinder, which is connected to the frame 7 and the additional frame 9 pivotally through the axes 12 and 13, respectively, mounted parallel to the axes 10. The additional supporting device is equipped with an idle roller 14, the supporting surface of which is made and flush with the support surface 6 of the support roller device 5 and the support plate 15 which is located directly beneath

cutting tool 3 and has a groove 1 b for exiting cutting tool 3; The surface of the supporting platform 15 is slightly higher than the supporting surface of the idle roller 14 and the rollers 6 of the supporting device 5.

A chute 17 is rigidly fixed to the frame 7, which is a continuation of the support platform 15 located in the lower position. The chute 17 is installed at an angle to the longitudinal axis of the support device 5. The second end of the chute 17 is directed into the storage box, 1: 8 ;. .

The device operates as follows. / Vv-. U:,;, ..,; ., .. -. . . V.

On the abutment surface of the rollers 6 of the abutment device 5, a blank 1.- is loaded using a freestanding loading mechanism or crane (not shown).

The stop 4, which can move along the length of the support device 5, is set with; taking into account the size of the cut-off end of the workpiece 1. The lead of the support device 5 is turned on, and the workpiece 1 is fed into the cutting zone to the stop 4 and is located along both sides of the cutting tool. 3. Depending on the length of the cut end of the workpiece 1, it will rest, if the cut end is long, on the support rollers 6: devices 5 located behind the cutting tool 3, if the cut end is short, on the support platform 15. Turn on the drive 11 of the additional support device, which rotates the additional frame 9 by a certain angle around the axes 10. When this is done, the actuator 11 rotates relative to the axes 12 and 13 through which it is connected, respectively, with the frame 7 and the additional frame 9. The clamp drive 8 and the workpiece 1 is clamped. The rotation and feed drives of the cutting tool 3 located on are turned on. tool head. 2 .. The workpiece 1.- is cut. In this case, the implementation of the supporting platform 15 is slightly higher than the supporting surfaces of the idle roller 14 and the rollers of the roller table 5, which allows the cutting to open during cutting, which affects the increase in the service life of the cutting tool 3.

The cutting tool 3 at the end of the cut extends into the groove 16 of the support platform; 15. At the end of the cutting, the cutting tool 3 is retracted to the upper position.

The cut end of the workpiece 1 is removed from the cutting zone as follows: if the cut end of the workpiece is long, then the stop 4 is withdrawn from the bottom of the support device 5, the roller conveyor drive is turned on, and the cut end is fed into the discharge zone, where it is removed from the support device 5 using a special unloading mechanism or using a crane; if the cut end of the workpiece is short, then drive 11 is turned on

additional supporting device, under the action of which the additional frame 9 is rotated around the axes 10 by a certain angle and the supporting platform 15 is aligned with the groove 17, along which

0, the cut-off part of the preform 1 rolls into the collecting box 18, which is discharged as it is filled.

The presence in the design of the device:

-additional frame connected to

5 by the frame of the rolling table pivotally through the axes. lying in a plane perpendicular to the longitudinal axis of the roller table and the carrier: an additional support device with a drive for moving it, made in the form of an idle roller and a support platform with a groove, allowed to cut the workpiece as
