Invented, and etoiots to LORI 31VDSTV at pipes 1 and prubkov dragged, em.

There are wire drawing mills containing traction chains with non-reversible drives, standing with a wave, bargaining (Carriages with upper: and lower rollers, connected by hinges with pulling tsegami with the help of levers, 1 направ lower направ guides. Nn: ADDITIONAL: A well-known mill is the unreliability of working carriages with the lower right side of the rail.

For the purpose of construction, the “elevated” and. In the proposed drawing mill, between the top and bottom gates, at the rack of the leading sprockets, an extra pole is installed, with a guide for opening the trolley to the top guide during the return stroke.

FIG. 1 shows the general scheme of the mill; in fig. 2 is a section along the line A-A of FIG. one; in fig. 3 - rear part of the mill.

The mill includes two endless chains /, each of which is derived from a common nerve and | In Nogo; drive 2; Two Carriages 3 and 4 with two p damels 5 and 6.

Non-advertisers 7 are attached to chains 1, which are axle oscillations of levers 8, to which inap iMpHO 1Pr; and nedi nepy Caret1K1i 3 and 4.

Additional trn section guide: lower horizontal, inclined 1 upper horizontal, coinciding with the level of the upper guide 12. An additional guide is installed at the rack of driving sprockets 9 with an opening between its upper, m horizontal portion and the end of the upper guide 12. Shadrin of the opening QI shorter than distance a2 between the first and second pair of rollers of the upper row of carriages. Neither idle :; There is a stand with gold 14.

The mill operates as follows. The long end of the workpiece (not shown in the drawing) is passed through the rack with the wire, and is caught by the carriage 4, the iKOTOpa "moves together with the workpiece

0 stars 9 on the lower guideline //. After finishing the drawing, the removed product is removed from the drawing of the drawing. Carriage 4, continuing to move, runs over the top 6 of the catalog 6 on the lower horizontal section of the additional guide 13 and, moving along the inclined section, goes through the opening and goes to the upper horizontal section of the additional guide. At the same time, the reverse movement of the carriage 4 begins. Since the width is less than a

The carriage 4, dvpga on top of the guide, comes down from its paired Clone section and is skipped by the first pair of lower rollers 5 on the lower guide P. At the same time, a third pair of BepxinMx. on one of the axles 15, on the levers 8, this second rail of the rollers 5 is lowering the lower guide on the lower guide // (see Fig. 3).

Fully lowered onto the lower guide, the carriage 4 approaches the rack with the VOLUME, behind the workpiece, ku, and the work cycle of the mill repeats.
