Description

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting long products such as rail.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that in the cutting line of sharp products containing a cutting device, feeding and receiving roller tables with lifting and lowering supports and supporting rollers with vertical axes, loading and unloading drives with guides installed perpendicular to the feeding and receiving roller tables with one of their sides, carriages with grippers mounted on these rails with the possibility of movement along them, according to the invention, drive rails

downloads are installed. Above the level of the feed roller table, their ends on the side of the roller table are made at an angle to the vertical, supporting rollers with vertical axes are installed on both sides of the cutting device in pairs-parallel to the longitudinal axis of the line, and on the supply and receiving roller tables only from the side opposite the guides, and said rollers located on the cutting device from the side opposite the guides are mounted to move in a direction perpendicular to the longitudinal axis line.

In addition, the lifting and lowering stops mounted on the receiving and feeding roller tables are located at the same distance from the cutting plane of the cutting device.

a

In FIG. 1 shows a line for cutting sharp products, general view; in FIG. 2 - same, plan view; in FIG. 3 is a view of a sharp article and a diagram of its cutting; in FIG. 4 is a section AA in FIG. 1; FIG. 5 is a sectional view BB in FIG. 1.

The cutting line for sharp products contains a loading drive 1, a feeding roller table 2, a cutting device in the form of a rail-cutting-drilling machine 3 with a saw 4, a receiving roller table 5, an unloading drive 6. Drives 1 and 6 of the loading and unloading contain guides 7 and 8, resting at one end on the frames 9 and 10 of the roller tables 2 and 5, the other on the racks 11 and 12, respectively / and the guides 7 of the loading drive 1 are mounted above the level of the horizontal drive rollers 13 the feed roller 2 and their ends are made with ends slanted at an angle to the vertical, and the guides 8 of the unloading drive 6 are installed at the same level with the drive horizontal rollers 14 of the receiving roller 5, the movable step carriages 15 and 16 installed in the guides 7 and 8 on rollers 17, with pneumatic drive and articulated drowning. my grippers 18 and 19 to move the sharp objects. The rollers 2 and 5 contain frames 9 and 10, horizontal driven rollers 13 and 14, single single supporting rollers 20 with vertical axes, stationary stops 21 and 22, lifting and lowering stops 23, 24 and 25, 26, movable rollers 27 and 28 with vertical axes, doubled with rollers 20.

Lini works as follows.

With an electric bridge crane, the sharp products 29 are stacked on the guides 7 of the load storage device 1 between the grippers 18 of the step carriages 15 to the side position, with the head facing the feed roller 2. When the step carriages 15 move forward (to the conveyor 2), the sharp products 29 with grippers 18 they move along the guides 7 by one step, and the workpiece close to the roller table rolls onto the rollers 13 of the feed roller 2 along the inclined end of the guides 7, set above the level of the feed roller 2, and spontaneously rotates from the side position to the side laying on the head and held in this position on one side by single rollers 20, and on the other by grippers 18 of the step carriages 15. With drive rollers 13 of the feed roller table 2, the sharp product 29 is fed to the rail-cutting drill 3. by size G (Fig. 3) with respect to the saw 4 and the movable roller 27 is pressed against the roller 20. After

clamping the product on the machine 3 and the segments of the front end (Fig. 3) of the extruded part to size Г the sharp product is unfastened on the machine 3, the movable roller 27 moves away from the product and it is pulled by rollers 13 and 14 of the rolling tables 2 and 5, keeping in position the head with rollers 20, 27 and 28, is moved by the end face Ж to the corresponding lifting and lowering stop 25 or 26

for pieces of sharp article 30 by size E (Fig. 3). After the cuts, the sharp articles 30 and 31 are released from the fastening and the drive rollers 14 of the take-up roller table 5 the sharp products 30 are fed

5 to the discharge accumulator 6, holding in position on the head by the rollers 28 and 20. After stopping the rollers 14 of the carriage 16, a step forward is made (from the roller table) and. move the sharp article 30 to the 8 guides 8 of the unloading drive 6, while the product from the position on the head spontaneously rotates to the side position with the head to the roller table 5. When the carriages 16 (to the roller table) move backward, the grips 19 pass, the recess under the sharp by the cradle product 30 and installed to further move it along the guides 8 of the unloading drive 6 at the next step forward of the carriages 16. Remaining on the machine 3, the rear part 31 of the sharp workpiece 29 with rollers 13 of the rolling table 2 is moved towards the unloading drive 6. Referring derzhiva in position on the head 27 and the first roller 20 and then

5 by rollers 28 and 20, and is set on the machine 3 relative to the saw 4 to size B (Fig. 3) and pressed by the roller 28 to the single roller 20. After clamping the article 31 on the machine 3 and the segments of the rear end (Fig. 3) are pressed out parts to size B, the product 31 is loosened on the machine 3, the movable roller 28 moves away from the product 31 and it is pulled by rollers 14 and 13 of the roller tables 5 and 2, being held in position on the head by rollers

5 28 and 20, and then 27 and 20, is moved by the end face And to the corresponding lifting and lowering stop 23 or 24 for cutting the sharp article 31 to size D (Fig. 3), after which it is released from the fastening

0 and drive rollers 13 and 14 of the rolling tables 2 and 5 through the machine 3 are transferred to the discharge accumulator b, being held in position on the head by the rollers first 27 and 20, and then by the rollers 28 and 20. After stopping

5 rollers 14, the product 31 is transferred to the guides 8 of the unloading drive 6 by stepping forward the carriages 16, similarly to the transfer of the product 30 described above. As products 30 and 31 accumulate on the guides 8 of the unloading drive 6, the last
