Description

(54) DISPOSABLE WIRE OF ROLLING GRADE The invention relates to the field of ferrous metallurgy and can be used in the rolling stands of a section mill of rolling mills of metallurgical plants. The leading wiring of the section rolling mill is known, comprising a wiring knife mounted relative to its hull with movement in transverse and longitudinal with respect to the rolling axis directions and provided with a drive for such movement kinematically connected with the rolling rolls 1. The disadvantage of the known wiring is its passive work when the direction of the rental is quite complex shape. Wiring is also known in which the wire knife is made of a composite of a series of sliders with an individual drive for their movement. The drives of the sliders are made of electromechanical and associated hinged THTE mi with sliders, hingedly mounted with fi rypHbnviH grooves in the wiring housing. This difference follows the movement speed of the wire knife pus.

MILLION FIG. Figure 1 shows the wiring with the drive for moving one of the knife sliders; a general view; in fig. 2 is a composite wire knife, top view; FIG. 3 is a sectional view in FIG. one; in fig. 4, 5, 6 - the same, at the time of the direction of rental; in fig. 7 and 8 - wire knife when rolling a profile of various shapes with a change in the shaped groove. The output wiring contains a wiring knife consisting of a row of sliders 1, between which separating tabs 2 are installed, Sliders and separating washers pivotally mounted in the housing 3 of the wiring with a finger 4 passing through the figured slots 5 of the sliders. The body is installed on the bar 6 rolling stands. Each slider is pivotally connected to the drive of its movement relative to the body. Each drive is made of electromechanical, kinematic, connected with rolling rolls 7. The drive contains ry 8 cranks, the end of which is hingedly connected to the fork 9 of the slide and the other end to the pusher 10 equipped with a bark 11, a clamp 12 and a return spring 13. Anchor 11 interacts with an electromagnet 14, included in an electrical circuit, powered by a source of electricity 15. This same circuit contains contacts 16, interacting with the contact. 17, located on the lever 18, terminating in a roller 19, interacting with one nz cams, 20, mounted on a camshaft 21, scooped with rolls. The number of cams is equal to the number of crawlers. The roller is pressed by the clamp 22.

Posting works as follows. In the initial position, the sliders are in the lower position. When you exit profile 23 of the rolls, i.e. when the rolls are turned, the block of cams mounted on the camshaft is rotated. A block of cams, each of which controls its own half-side, actuates its drive. The slides are mixed depending on the configuration of the rolled profile.

When each cam is rotated, the lever 18 (when the roller 19 rushes over the cam profile protrusion) closes the drive electric circuit by contacts 17 and 16. The electromagnet 14 actuates, changing the position of the lever 8 through the pusher 10. The lever 8 pushes the follower through the pivot fork 9. in motion relative to its body 3. Movement occurs along the figure groove 5.

Moving other sliders is similar. The amount of movement of the sliders when adjusting wiring to other profiles is changed by swapping the support of the lever 18.

The required trajectory of the slider in its plane-parallel movement is provided by the shaped grooves 5 and pallesry 4. In the case of molding on the profile 23, the depth of the half-hole is retracted only to the rear to avoid its collision with the protrusion of the roll forming the recess. For this, the shaped groove is elongated in a horizontal direction. - In the case of molding on the profile 23, the protrusions of the slider are retracted and down, for which the holes are made arc-shaped.
