Description

The invention relates to the field of pipe production, and more specifically to devices for introducing lubricant into the sleeve before rolling in the production of seamless pipes.

A device for feeding powdered lubricant into a liner containing a hopper with lubricant, a portioned lubrication mechanism (ed. Certificate of the USSR No. 398304 B21B 45/02, decl. 10/07/1971, publ. 12/02/1974).

The mechanism of portioned supply of lubricant is made in the form of a vertical drive screw located in a channel mounted on the side of the hopper. The screw dispenser provides a stable supply of lubricant in the form of an upward flow crossing the axis of transport of the sleeve. The sleeve, crossing the flow, captures a certain portion of the lubricant. Grease that does not fall into the sleeve is poured back into the hopper.

The disadvantage of this device is that the dry powder lubricant captured by the sleeve when crossing the flow is usually located only a short length from the beginning of the sleeve and, therefore, cannot be qualitatively distributed over the entire inner surface of the sleeve.

It is also known a device for supplying powdered lubricant to the inner surface of a liner containing a hopper with lubricant, a portioning lubrication mechanism, a nozzle connected to a pressurized air supply system (see ed. Certificate of the USSR No. 492326, B21B 45/02, decl. 19.07 .73, publ. 11/25/1975). The nozzle is inclined to the moving sleeve integrated into the wiring installed on the axis of movement of the sleeve and is connected to the dispenser by a channel in which the pusher with the drive and the pneumatic system are located. The mechanism of portioned supply of lubricant is made in the form of a housing with a hole and a shutter and is installed coaxially with the outlet of the hopper. The serving size is controlled by a shutter.

The disadvantage of this device design is that it does not provide high-quality lubrication on the inner surface of the liner, since dry lubricant is supplied at an angle to the wiring. Another disadvantage of the known device is that during the purging process, the powder enters the gaps between the pusher and the housing of the portioned lubricant supply mechanism, and this makes it difficult to move the pusher in the housing.

The closest in technical essence is a device for supplying powdered lubricant to the inner surface of the liner, containing a hopper with lubricant, a portioned lubrication mechanism, a nozzle connected to the air purge chamber under pressure (ed. Certificate of the USSR No. 263542, B21B 45/02, decl. 02/25/1969, publ. 02/10/1970). The nozzle, the purge chamber and the chamber with a portion of the lubricant are fixed on a lever that rotates in the horizontal plane. The chamber with a portion of the lubricant and the nozzle are mutually perpendicular to the plunger of the pneumatic head, which is moved by impact of the end face of the sleeve on the plunger and causes a stream of air blowing a portion of the lubricant into the sleeve.

A disadvantage of the known design of the device for supplying powdered lubricant to the inner surface of the liner is that for the nozzle to operate, the liner must hit the plunger of the pneumatic chamber, that is, its movement with a certain force and, consequently, an increase in the time of applying lubricant. Another disadvantage is that there is no supply of lubricant to the sleeve in portions of a certain amount, and this excludes the possibility of using the device for sleeves of different diameters and its high-quality application.

The objective of the present invention is to provide a device that allows you to apply powder lubricant on liners of various diameters.

This object is achieved in that the device for supplying powdered lubricant to the inner surface of the liner containing a hopper with lubricant, a portioning lubrication mechanism, a nozzle connected to a pressure purge chamber and a portioning lubrication mechanism, according to the invention, it is equipped with a stop for a sleeve with a vertical groove in a spring-loaded heel, in which a nozzle is mounted with the possibility of vertical movement, while the portioned under The lubricant is equipped with a revolution counter, the case of this mechanism and the purge chamber are mounted on the hopper coaxially with the outlet of the hopper, and the purge chamber is connected to the nozzle and the air supply pipe under pressure by a flexible element. The nozzle mounting means vertically is made in the form of a slider mounted on the stop and a screw fixing its position.

Such a constructive implementation of the device for supplying powdered lubricant to the inner surface of the liner will allow high-quality lubrication of the inner surface of the liners of various diameters due to the fact that the nozzle is always adjusted to the axis of the liner, since it is installed with the possibility of vertical movement, and this will ensure uniform distribution of lubricant along its inner surface. At the same time, for each size of liners, a portion of the lubricant defined for this size is supplied. The means of vertical movement of the nozzle ensures its rigid fixation during operation. The use of a flexible element for connecting the nozzle to the purge chamber also allows the nozzle to be tuned to different sleeve diameters.

To explain the invention, a specific embodiment of the invention is provided below with reference to the accompanying drawings, in which:

The device for supplying powdered lubricant to the inner surface of the liner consists of a hopper 1 with lubricant, a mechanism 2 for the portioned supply of lubricant, a chamber 3 for purging with air under pressure and a nozzle 4 connected to the chamber 3 for purging. A housing 5 with an intermediate sleeve 6 is mounted coaxially with its outlet opening. A mechanism 2 for supplying lubricant in the form of a vertical screw 7 with a drive for its rotation, consisting of a gearbox 8 and an electric motor 9, and a counter of 10 revolutions is mounted in the hopper 1 and the housing 5. . On the housing 5 is rigidly fixed chamber 3 purge air under pressure. The purge chamber 3 of the flexible element 11 through the nipple 12 is connected to the nozzle 4, and the flexible element 13 with the pipeline 14 for supplying air under pressure. The nozzle 4 with the possibility of vertical movement is mounted inside the stop 15 with a spring-loaded fifth 16. In the heel 16 there is a vertical groove 17 in which the front end of the nozzle 4 is placed, and a slider 18 is mounted at the rear end of the stop 15 through which the nozzle 4 is passed, the vertical position of which fixed with screw 19. Slider 18 and screw 19 are used to adjust the axis of the sleeve.

The device operates as follows.

The sleeve 20, moving along the roller table (not shown) to the stationary stop 15, stops. The nozzle 4, by means of the nozzle installation means, is mounted vertically along the axis of the sleeve 20. The mechanism 2 of the portioned supply of lubricant is turned on. The screw 7, rotating from the electric motor 9, delivers a portion of lubricant strictly defined for a given diameter of the sleeve through the sleeve 6 into the purge chamber. Then, pressure air is supplied from the pipe 14, which injects lubricant through the nozzle 4 onto the inner surface of the sleeve 20.

The proposed device for supplying a powdered lubricant to the inner surface of the liner in comparison with the known allows lossless and high-quality supply to the inner surface of the liner strictly defined depending on the diameter of the amount of lubricant.
