(54) DEVICE FOR CUTTING AND EDGING CERAMIC

. PIPE

The invention relates to devices for the treatment of building materials and can be applied for the production of ceramic pipes. A device for cutting and mandrel ceramic pipes is known, which includes a housing, an actuator and a cutting unit CU. A disadvantage of the known device is that its structure is complicated and therefore unreliable, moreover, it is very difficult to maintain. The closest technical solution is a device for cutting and mandrel of kersey pipes, including a frame, a drive, a rotary blade, a neural drive disk and a feed mechanism of the cutting disk 12. A disadvantage of the known device is the inconvenience of its maintenance; during operation, such as the feed of the rotating non-driving cutting disc, the axis is screwed. The purpose of the invention is to simplify the maintenance of the device in the process of re-eani and mandrel of ceramic pipes. In order to achieve the ceramic pipes, including the frame, the drive, the rotating non-driving disc, the drive disk and the feed disk of the cutting disk, the feed disk of the cutting disk contains a driving and driven ring with stops and a double-arm lever, on one arm of which is installed. the cutting disk and the other interacts with the stops, with a double-shouldered lever pivotally mounted on the driven ring, and the cutting disk is provided with a roller with knurled protrusions, one of the stops on the blade of the disk is configured to regulation in the taigencion direction. FIG. 1 shows a general view of the device; in fig. 2 - cutting body design. The device consists of a bed Ij on which a rack 2 is mounted, to which case 3 is fixed. An outer drive rim is put on the case, consisting of two rings - gear 4 and smooth 5 rigidly interconnected. A drive ring 6 is attached to the drive rim, on which lugs 7 and 8 are fixed. On the hub of the drive ring, a driven ring 9 is mounted with lugs 10 and 11 and a double-arm lever 12 is hingedly mounted at one end of which is fixed 1EOLIC 13 with knurled spikes And cutting edge, and the other. The end of the lever is inserted into the plug, which is located between the stops 7 and 8 on the drive ring and the stops 10 and 11 on the driven disk. For braking the ring 9 at the time of cutting by the tube roller 13: the driven ring is pressed to the driver with springs 14. The driven ring 9 is held on the hub of the drive ring b by means of a flange 15, which is attached to the body with screws and allows the ring 9 to rotate relative to rings b. The drive ring is driven by a drive 16,

The device for cutting and mandrel ceramic pipes is as follows. When the actuator 16 is turned on, the drive ring bis is driven by the stop 7, acting on the end of the double-arm lever 12, the roller 13 is lowered and cut into the pipe. At the same time, the driven ring 9 is braked with crackers 14. With further rotation of the leading ring b through the lever 12 and the stop 11, the driven ring 9 is engaged, resulting in the rolling of the outer circumference of the barrel with the roller 3. In this case, the pipe is cut off and at the same time grooves roll over it. Then the reverse is activated. The drive wheel b starts to rotate in the same direction and with the help of the stop 8 acts on the lever 12, the roller 13 is moved out of the pipe's cutting barrel to its original position.

The use of this invention will simplify the design for

cutting and mandrel pipes, reduce the metal consumption of the device, improve its reliability and quality of processing of ceramic pipes, as well as reduce operating costs for its maintenance.

Claims (2)

1. A device for cutting and mandrel of cum lamic pipes, including a frame, a drive, rotation with a non-driving cutting disk and a cutting disk feeding mechanism, characterized in that, in order to facilitate maintenance, the cutting disk feeding mechanism contains a driving and driven ring with stops and two shoulders a lever, on one shoulder of which a cutting disc is mounted, and the other interacts with stops, with a double-arm lever articulated 0 is mounted on the driven ring, and the cutting disk is equipped with a roll with knurled protrusions. 2.
