CS252158B1 - Equipment for separating longitudinally divided profiles on a profile track - Google Patents

Abstract

The device for separating two profiles, resulting from the division of one profile on the rolling line, consists of a switch-off device, a separator and a switch. Both halves of the switch are controlled by levers mounted on the shaft, the left lever is disconnected from the shaft by the switch-off device and the separator is mounted on the halves of the switch. The separator consists of a centering, inner separator and outer part. When the separator is installed on a single-core conveyor, separating rulers are placed in the space between the separator and the double-core conveyor.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for separating two sections formed by longitudinal sectioning of one section on a rolling mill.

T-profiles and non-uniform angles have been rolled one by one. However, the apparatus for this method requires a considerable number of working rolls. Newer technology then allows rolling of the I-profile and U-profile, where before the straightener are disc shears, which cut the profile lengthwise. The disadvantage is the necessary synchronization of the straightener and the shears. At the same time, the straightening axis is also unsatisfactory. In order to improve it, the split profiles between the disc lowerers and the straightener must be twisted with twisting rollers. Twisting above the yield strength then worsens the leveling conditions. The material is also twisted on its own during the cutting process, and in the opposite direction, burrs arise during cutting, which cannot be removed in the straightener due to the straightening axis. The I- and U-sections can also be split on the rolling mill, but then, the two split sections are conveyed to each other on the cooler.

The aforementioned drawbacks are eliminated by a device for separating longitudinally divided profiles on a profile track consisting of a cut-off device, a separator and a switch according to the invention, which is based on the fact that the right lever controls the right half of the switch; the left half of the switch. The left lever is disconnected from the shaft by the shut-off device and a separator is mounted on the switch halves. Another principle is that the separator is mounted on a single-core conveyor and separation rulers are arranged in the space between the separator and the two-core conveyor. The essence further comprises that the separating device consists of a centering part, an inner separating part and an outer part.

The switch-off device disables the switch function, then a separator is placed on the switch to ensure splitting and transport of the longitudinally cut pieces to each side of the refrigerator.

The advantage of the device is, besides transporting the individual pieces to the refrigerator, that synchronization of the operation of the scissors and the straightener is eliminated and labor productivity is increased.

The attached drawing shows a device for separating longitudinally divided profiles, in which Fig. 1 shows a switch, Fig. 2 shows a cross-section of the switch, Fig. 3 shows a longitudinal section of the separator, Fig. 4 is a plan view thereof; FIG. 5 is a cross-sectional view of the deposited separator at the switch; and FIG. 6 is a ruler-separating device.

On the shaft 15, a right lever 13 operating the right half of the turnout 3 is fixed and a left lever 14 operating the left half of the turnout 1 is loosely mounted (FIGS. 1, 2). The left switch point 1 is controlled by the switch-off device 2. The arrangement of the controls of the left switch point 1, the switch device 2, the right switch point 3, the drive 7, the right lever 13, the left lever 14 and the shaft 15 can also be reversed. On the left and right half of the turnout 1, 3 there is a separator 4 (Figs. 3, 4, 5), which consists of a centering part 5, an inner separating part 6 serving for self-separation and an outer separating part 8 which is fixed to the turnout. and prevents the profile material 11 from slipping off the two-core conveyor 9. The splitting device 4 may also be located on the single-core conveyor 10 (FIG. 6). Separation rulers 12 are then positioned between the separator 4 and the two-core conveyor 9 to keep the fragmented profile material 11 apart.

In preparation for rolling the longitudinally divided profiles on the profile track, the left switch point 1 (Fig. 1, 2), controlled by the cut-off device 2, is set to the lower position. The right side switch 3 is lowered via the drive 7 via the right lever 13 and the shaft 15. The separator 4 is placed on the left half 1 and the right half 3 of the switch. Two pieces of profile material 11 enter one another on a single-core conveyor 10 into centering parts 5, where they are centered and are subsequently separated by means of the inner and outer separating parts 6 and 8 and enter the double-bed conveyor 9.
