Abstract

The invention relates to rolling production, and more specifically to devices for the lateral transfer of rolled products in production lines for inspection and finishing. A feature of the device for the cross-transfer of round-rolled products is that between the successive shifters 1 and 2 there is a mechanism for extracting rolled products from the stream. It is made in the form of a vertically moveable frame 4, carrying a cantilever mounted biconical rollers 5 with a drive 7 and supporting prisms 16 located above them. The roller and the prism form a pair, in which the tops of the grooves are located on the same vertical. 2 Il.

Description

The invention relates to the field of rolling production, and more specifically to devices for the transfer of rolled metal and can be used most effectively in production lines for inspection and finishing of pipes.

A device is known for distributing round-rolled steel from an inclined grate between the threads of a multi-line roller table (ed. St. No. 301195. Class B 21 B 39/18, ZA. 31.03.70).

It contains levers mounted with an inclined lattice on vertical shafts with stops and a drive for their rotation to a fixed position. For each thread of the roller table, lifts with a receiving profile surface are provided.

The closest in technical essence (prototype) is a device for the transverse transfer of rolled products with a sample of the flow of defective rolled products for laying in the pocket described in the ed. St. No. 1505616, cl. B 21 B 39/00. Ow. 08/07/87. This device contains rack and lever shifters and a mechanism for hauling a rolling stock out of the stream installed between them. The mechanism for hauling a rolling stock out of a flow is made in the form of pivotal in a plane perpendicular to the direction of movement of the rolled metal, levers held. a common drive through gears, on which the sprockets are rigidly fixed, and at the end of each of the levers a support roller with a sprocket connected by a chain with a drive sprocket is pivotally mounted.

A disadvantage of the known construction of the device is that when sampling pipes, the flow through the main flow (in the transverse direction) decreases due to the loss of time for returning the transfer levers to the receiving position of the pipes, since return of the transfer levers is possible only after sampling.

The disadvantage is, in addition, low reliability, due to possible (L

misalignment in the work between the sampling mechanism and the lever shifter.

The purpose of the present invention is to improve the performance and reliability of the device.

The goal is achieved by the fact that in the device for the cross-transfer of round steel, including successively placed shifters and an installed mechanism for hauling a rolling stock out of the stream, according to the invention, the mechanism for hauling a rolling stock from a stream is made in the form of a vertically moveable frame carrying a console mounted biconical rollers with a drive and supporting prisms located above them, and the roller and the prism form a pair, in which the tops of the grooves are located on the same vertical.

Such a constructive implementation makes it possible to combine in time the sample of the rolling stock and the installation of the supporting prisms in the transfer line for transferring the rolling along the main flow. This improves the performance and reliability of the device.

FIG. 1 shows a device for the transmission of round rolled steel, general view: in FIG. 2 is a section A-A in FIG. one.

The device for the cross-transfer of round steel, for example, pipes, contains successively placed shifters 1 and 2, for example, rack, a mechanism for hauling a rolling stock from the stream and an outlet roller conveyor 3. There is a frame for hauling the rolled stock from the stream 4 and biconical rollers 5, cantilever mounted on racks b rotatably from drives 7. Racks 6 are mounted on frame 4. Frame 4 by means of brackets 8, levers 9, axles 10 and bearings 11 are mounted on racks 12. Frame 4 has the option of vertical moving by means of a pneumatic actuator 13 through t gu 14, levers 15, 9 and brackets 8. On the uprights 6, the supporting prisms 16 are rigidly fixed above the biconical rollers 5 so that the supporting prism 16 and the biconical roller 5 form a pair with the tops of the grooves a and b are placed on the same vertical. The distance between the grooves a and b is chosen equal to the height h of raising (lowering) the frame 4.

The device works as follows

Shifters 1 and 2 of the pipe 17 are fed in the transverse direction.

This frame 4 is in the lower position. The notches of the supporting prisms 16 are located in the lines of the shifters 1 and 2. From the shifter 1, the pipes 17 enter the

the recesses and support prisms 16 are removed from them by the shifter 2 and transmitted further downstream. For sampling pipes from the transversely transmitted stream, for example, for control, frame 4 is raised

pneumatic actuator 13 through tg 14, levers 9, 15, and brackets 8. The notches of biconical rollers 5 occupy a position corresponding to the line of the shifter 1. The tubes 17c of the shifter 1 enter the

the recesses b of the biconical rollers 5, the recesses of the support prisms 16 are at the same time above the line of the shifters 1 and 2 and do not participate in the transverse transfer of the pipes. Then the frame 4 is lowered pneumatically 13

In this case, the recesses of the biconical rollers 5 are installed in the line of the outgoing roller table 3, and the recesses and supporting prisms 16 are again installed in the line of the tilters 1 and 2. The drives 7 of the biconical rollers 5 are turned on and the pipe 17 on them and the discharging roller table are transported 3 in the axial direction on the plot control. At the same time, the transferors 1 and 2 pass the pipes in the transverse direction through the v: capacitor support prisms 16. The process of lateral transfer of the pipes continues until the next sample, which again raises the frame 4 to receive the pipe with biconical rollers 5 and lower the frame 4 for axial delivery of the pipe biconical rollers 5 and outgoing roller table 3 to the control section.
