SU1579655A1 - Arrangement for longitudinal separation of moving rolled stock - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used in the rolling industry for separating the rolled products obtained by multi-strand rolling. The purpose of the invention is to increase productivity and reduce production space by combining longitudinal separation and rolling of the rolled products. When entering a rollout device consisting of three ovals connected by bridges, the metal is caught by the rotating disk knives 2 and 3. As a result of this, the knives 2 and 3 cut the bridges between the ovals with the cutting edges 4. At the same time, due to the contact of the ovals with the surfaces 5 and 7 of the knives and additional discs 6, the cross sections of the roll ovals rotate. 2 Il.

Jda ф ^ ,, · 1, ^ a diagram of a device for the longitudinal separation of moving • rolled products in working position is shown; in FIG. 2 is a profile of the rolled stock obtained by multi-strand rolling.

A device for the longitudinal separation of rolling stock contains installed on the upper and lower shafts 1 of the upper 2 and lower 3 circular knives with a diameter D and a width b with cutting edges 4 and conical surfaces 5, as well as additional disks 6 with a diameter D located at opposite ends of the upper and lower the device shafts and having conical surfaces 7. The distance between the disk knives 2 and 3 and the disks 6 is equal to I, and the overlap value of the knives is equal to δ. The angle φ of the cone of conical surfaces 5 and 7 is 20 ... 25 °. The height of the generatrix of the lateral surface 8 of the cylindrical shape of the disk knives 2 and 3 and the disks 6 is (0.15 ... 0.2) 1.

The device operates as follows.

When you enter the device roll, consisting of three ovals 9 connected by jumpers, the metal is captured by the rotating disk knives 2 and 3, as a result of which the knives 2 and 3 are cut by the cutting edges 4 of the jumper between the ovals. At the same time, due to the contact of the ovals with the surfaces of the 5 and 7 knives and additional disks 6, 5 gates of the cross sections of the ovals 9 of the roll occur.

Claims (1)

Claim A device for longitudinal separation of moving rolled products, mainly produced during multi-ribbed rolling, containing circular knives on the upper and lower shafts with working and non-working edges formed by the intersection of their side and end ^ 5 surfaces, and two additional disks, characterized in that, in order to increase productivity and reduce production space by combining longitudinal separation and tilting of the rolled products, additional disks are located at 20 opposite ends axes of the upper and lower shafts at a distance from adjacent circular knives, equal to the distance between adjacent circular knives, parts of the side surfaces of additional disks and 2 to ₅ circular knives adjacent to one of the end surfaces and to the idle edge, respectively, made conical with a cone angle of 20 ... 25 °, while the vertices of the conical surfaces of the additional disk and circular knives of one shaft are directed in the opposite direction with respect to the direction of the vertices of the conical surfaces of the additional disk and ovyh knives of the second shaft, and the height of the side surface generatrix of the cylindrical shape of circular blades and additionally up to 35 disks is 0.15 ... 0.2 the distance between adjacent disk blades.
