Description

Изобретение относитс к металлур гическому производству/ в частности к устройствам дл механической зачистки с помощью иглофрез круглого проката от окалины, ржавчины и т.п.The invention relates to metallurgy production / in particular to devices for mechanical cleaning with the aid of round-rolled needles for descaling, rust, and the like.

Известно устройство дл зачистки круглого проката, включающее установленный в корпусе устройства барабан с приводом его вращени и смонтированную в барабане пару соосных друг другу торцовых иглофрез, снабженных приводом вращени вокруг собственных осей, вьшолнённь в виде размещенного в барабане планетарного редуктора 1.A device for stripping round rolled products is known, comprising a drum installed in the device housing with a rotation drive and a pair of end-face needle-cutters coaxially aligned with each other and fitted with a rotation drive around their own axes mounted in the drum as a planetary gear 1 placed in the drum.

Однако это устройство характеризуетс недостаточной жесткостью и отсутствием механизма опоры и центрировани в устройстве заготовки, что ограничивает возможность применени больших усилий резани и снижает производительность процесса, а также ведет к снижению качества очистки.However, this device is characterized by insufficient rigidity and the lack of a support and centering mechanism in the workpiece device, which limits the possibility of applying large cutting forces and reduces the productivity of the process, and also leads to a decrease in the quality of cleaning.

Целью изобретени «вл &гс повышение производительности и качества очистки.The aim of the invention is to increase the productivity and quality of cleaning.

Поставленна цель достигаетс тем, что в устройстве дл сплошной зачистки проката, включающем уста- This goal is achieved by the fact that in the device for continuous stripping of rolled products, including

Claims

30 are rigidly connected to the drum 4. The station Kahn 2 is connected via a chain drive 5 and a gearbox 6 to an electric motor 7. Coaxially with a cup 3 is fixed, but the bevel wheel 8, in engagement with which are two diametrically located bevel satellite gears 9, through gears 10-I and 12-13 are associated with two coaxial end iglovrezami 14. On both sides of the needle-cutter on one axis with cups 2 and 3 in the drum 4 symmetrically fixed two conical wheels 15. In contact with each wheel 15 are four bevel pinion shaft 16, three and From which 1b, 166, 16b are evenly spaced around the circumference and with their threaded shanks 17 are connected to housings 18 carrying the guides; rollers 19. Two diametrically located bevel gears 16a and 16g are kinematically connected with knives 20 and 21. the sides of each pinion shaft 16 are milled square. A billet (pipe) 22 passes through the through holes in glasses 2 and 3. Electric motor 7 with gearbox 6 is mounted on the upper frame 23, which forms a needle-milling zone casing with the base of the obcian machine. The device works as follows. When the electric motor is turned on, the double-support drum 4 through the chain drive .5 and the gearbox receives rotation relative to the stationary bevel wheel 8. Gears 9, running along with the drum along the teeth of wheel 8, are also rotated around their axes, which through interchangeable gears 10-11 and 12-13 are transferred to both end igloprezam 14. Together with the drum 4 rotates the conical wheels 15 and the tapered shafts-gears 16. Consequently, the guide roller 19 rolls around the treated pipe 22, keeping it in the zone brabotki. In addition, two shaft-shafts 1ba and 1bg are associated with knives 20 and 21 located on both sides of the workpiece, which support the workpiece in a plane perpendicular to that in which the axes of the needle-cutter 14 are located, preventing it from bending under the action of forces cutting. The adjustment of the position of the rollers and knives is carried out synchronously by rotating the milled shank to either side of the gears 16. In this way, the needles 14, rotate around their axis and simultaneously rotate with the drum 4 around the supplied rod. (Or tubes) 22 are processed its continuous cleaning, fixing the workpiece in the cutting zone with the help of knives and guide rollers allows to significantly expand the range of cutting forces without fear of deforming the workpiece during processing. Apparatus of the Invention A device for continuous stripping of round rolled products, including a drum installed in the device case, equipped with a rotation drive, and a pair of end-face needles coaxial to one another, mounted in the drum, provided with a rotation drive around their own axes, made in the form of a planetary gearbox placed in the drum, characterized by that, in order to increase the productivity and quality of cleaning, the drum is made double-support and is equipped with a mechanism for centering the workpiece mounted in it cleaning, made in the form of groups located on both sides of the needle-cutter, evenly placed around the circumference of the drum axis of the guide rollers and installed in a plane parallel to the ends of the needle-cutter, a pair of knives, and the rollers and knives are kinematically connected by a mechanism of their synchronous movement in the direction to the workpiece.
