Abstract

The invention relates to a machine tool industry, in particular to devices for feeding ingots to cutting machines. The purpose of the invention is to improve the accuracy of the cut. The ingot 1 is lifted up by the prisms 21 above the rollers 20 of the roller table 18 and is oriented downwardly due to the fact that the working surfaces of the prisms 21 are provided with rollers whose axes are parallel to the longitudinal axis of the roller table 18. The self-centering clip 27 with the jaws of the supply carriage 24 rotating in the vertical plane captures the ingot 1 from turning around its axis. Prisms 21 are lowered. The unstressed end of the ingot 1 is lowered onto the rollers 20 and, in this position, the ingot 1 is fed under the clamp 7 of the cutting machine 2. 6 Il.

Description

The invention relates to a machine tool industry, in particular, to devices for feeding workpieces to cutting machines.

The purpose of the invention is to improve the accuracy of the cut.

FIG. 1 shows a device, a plan view; in fig. 2 - the same. front view; in fig. 3 - prism; in fig. 4 is a kinematic diagram of the trolley; in fig. 5 is a diagram of an ingot clamping on a cutting machine; in fig. 6 - agitator, side view.

A device for feeding ingots t to a cutting machine 2 containing a frame 3, a saw head 4, a feed carriage 5, a support prism 6, a clamp 7 supporting rollers 8 consists of a storage device 9 including inclined beams 10 mounted on supports 11 and restrictive lugs 12 mounted on the beams 13. On the supports 11, the tedders 14 are installed in the form of two beams having 15 rotations at one end, 15 rotations at the other end, and 16 hydrophilters at the other end. Before the drive installed

the mechanism 17 for the piece delivery of ingots 1 and the conveyor 18, consisting of a housing 19, on the upper plane of which non-driven rollers 20 are fixed. Between the rollers there are two prisms 21 with a vertical displacement drive, on the working surfaces of which additional rollers 22 are mounted parallel to the axis of the roller table 18. On the front wall of the roller table, on the guides 23, the feed carriage 24 is mounted for movement in the longitudinal direction, in the housing 25 of which a roller: / 26 and a self-centering clamp 27 are mounted, on the clamping elements x 28 of which the jaws 29 are rotatable in the vertical plane. The cutting part 30 of the ingot 1 remains on the left side of the support prism 6.

The device works as follows. .

The ingots 1 are loaded by a crane onto the hopper 9. After the crane cables are withdrawn, the hydraulic cylinders 16 turn on

agitators 14, which perform vertical reciprocating movements, facilitate the movement of ingots 1 to the restrictive stops 12 and to the stops of the mechanism 17 for piecewise delivery of ingots 1. The mechanism 17 for piecewise issuing of ingots 1 shifts them one by one on rollers 20 of the roll table 18. Thereafter, two prisms 21 are moved to the up position. The ingot 1 located on them, under the action of the moment caused by the displacement of the center of gravity relative to the ideal axis, turns on additional rollers 22 with a concavity downward. Then along the guides

23, the trolley 24 fits into the zone of the prism 21 and clamps the ingot 1 with a self-centering clamp 27. After this, the prisms 21 are lowered to their original position, and the left end of the ingot is lowered onto the rollers 20. In this case, the jaws 29 located on the clamping elements 28 are in clamped state, turn around their axes, then the carriage drive turns on

24 and the ingot 1 is fed to the zone of the support prism 6 and the clamp 7 of the cutting machine 2. The ingot is pre-clamped to the left end. The cart 24 separates the clamping elements 28 with jaws 29. In this case, the clamp 7 finally clamps the ingot until it touches the prisms 6, orientation of the left end relative to the cutting plane. The right end is raised. Cart 24 goes to its original position. The carriage 5 also clamps Ingot 1 with grips. The first billet is cut. Further supply of the ingot 1 to the cutting is performed by the carriage 5. After the cut off part 30 of the ingot 1 is removed on the machine 2

the ingot 1 is unclamped and the carriage 5 with its grabs feeds it to cut the next part. Clamp 7 is triggered, the orientation of the ingot 1 relative to the cut plane. In this case, the clamping force 7 overcomes the considerably smaller clamping force of the jaws of the carriage 5. After the orientation of the ingot 1, the carriage 5 unclenches its grips, returns to its original position and again clamps the ingot 1. The second part of the ingot 1 is cut. The work of the clamp 7 and the grips of the carriage 5 alternate with this in such a way that the ingot 1 is in a clamped downward concavity at the time of feeding and cutting.
