Description

The invention relates to metallurgical equipment, in particular to equipment used in rolling mills for tilting billets on racks and moving them. A device for transferring workpieces is known, comprising a rack mounted under the rack on rail rails of a carriage with protrusions embedded with a finger and a support, directing the reciprocating movement of the carriage 1}. However, when moving a pack of billets, this device does not allow separate blanks to be separated from it. The closest to the technical essence and the achieved effect to the proposed is a device for tilting and transferring billets, including a shelf with a ledge, a wedge canter, separation cart with driven movement mounted on rail guides and having a front protrusion and a rear stop 2, However, the known device does not allow to quickly select the workpiece necessary for turning-over In this case, since the wedge is not visible to the operator when lifting this workpiece, it is therefore necessary to maneuver the trolley in order to orient the wedge. Under the required workpiece, it takes extra time. The purpose of the invention is to increase productivity during tilt and simplify maintenance. This goal is achieved by having a device for selectively turning and transferring blanks, preferably in front of the heating furnaces of the rolling mill, including a ledge rack, a tilter mounted under the rack on the rail guides of a separating carriage with a front lug with sunken fingers to separate the blank from the stack. on the ledge and rear stop for moving the stack of blanks along the rack, the drive of the reciprocating movement of the trolley, is equipped with a feed trolley with a number of sunken fingers and guides with a copier mounted between the front protrusion of the separating carriage and the rear stop and connected with it, while the guides with the copier are installed under the rail guides, and the stop is above the front protrusion by a value not less than the protruding protrusion pieces of sliding fingers. FIG. 1 shows the device, the initial position /, when loading blanks on the rack; FIG. 2 is the same when leveling the blanks; in fig. 3 - the same at the time of separation of the workpiece from the package; FIG. 4 is the same at the moment of supplying the blanks to the working area of the turning device; in FIG. 5, the same plan view; fig. b shows the device at the time of the separation of the subsequent preform; Fig. 7 is the same, at the time of the submission of the next billet to the working area of the tilting device and transferring the previous billet to the rack or live rolls. The device consists of a rack 1 with a ledge 2 for separating a pack of blanks 3 by increasing its grip area, a separating carriage 4 with a front protrusion 5, which is equipped with two pairs of retracting fingers b, and with a back rest 7, the top of which is not lower than the protruding part of the fingers b. The stop 7 is designed to orient, align and pack the blanks 3 on the rack 1. The cart 4 is mounted on rail guides with the possibility of reciprocating movement from a drive (not shown) connected to the cart 4 through pull 9 and crank 10, V the separating carriage 4 has a feeding carriage 11 with a series of sunken fingers 12 built in. The upper surface of the protruding part of the fingers 12 is radially formed so that, when the carriage 11 moves forward, the fingers 12 lying under the blanks slip and not separate. from the pack. The trolley 11 is connected with a separating trolley 4 pivotally thrust 13 and mounted on guides 14 with copiers 15. The latter allow the package of workpieces 3 to be moved 3 by fingers 12 by an amount less than the movement increment of the carriage 4, as the blanks are caught by diving fingers 12 at the moment when the feeding carriage 11 emerges from the copiers 15 onto its upper surface, with THIS, they allow fingers 12 to be removed in the initial position of the carriage 4 below the top of the rack 1, which fingers 12 are prevented from breaking during loading of the rack 1 by blanks 3. The device has a pant The holder 16, for example, is in the form of a bending fork 17, which is mounted in the zone of the selected blank 3 for turning. The device operates as follows. In the initial position (FIG. 1), the separation cart 4 is in the extreme right position, the feeding cart 11 is on the guides 14, and the fingers 12 are located below the upper surface of the rack 1. In this position the cart 4 and 11 are loaded by crane billet 3 on the rack 1 in the area of the supply trolley .11. The impulse to turn on the drive of movement of the trolley 4 comes from the control panel and through the cranks 10, with the pull 9, the cart performs a ON-ON rotation of the crank a reciprocating movement. When moving the carriage 4 forward by the stopper 7, the cargo carriage 3 aligns and moves along the rack 1 forward (Fig. 2), and when it moves backward, the carriage returns to its original position (Fig. 3) -.

When the drive is restarted while the trolley 4 is being moved, the feed carriage 11 moves along the guides 14 by means of the thrust 13 via the guides 14 and. then on the copier 15 until reaching its upper surface (Fig. 4). During the exit of the feeding trolley 11 along the copier 15, the last finger 12 extends beyond the extreme blank 3 of the bag and transfers the packet to a step equal to not less than the width of the face of the blank 3. When this repeated movement is performed, the back fingers of the b are separated from the ledge 2 by the blank 3 and fed to zone of the turner 16 with the edge 17 (Fig. 4 and 5). If necessary, make turning on include tilter 16 (Fig. 5). The separation of the workpiece 3 is carried out as follows. When moving the cart 4 forward with the rear fingers 6 from the lower surface of the ledge 2, the front blank 3 is seized and separated from the bag, the fingers 12 of the feeding cart 11 at this time move under the blanks 3, without touching the stack packet 3 (while the bag is at rest ). The packet begins to be transmitted only when the trolley 11 leaves the copier 15 on its upper surface. Therefore, during the course of trolley 4 forward the front billet

3 goes a longer way than the entire package of blanks, which passes a path not less than the width of the face of the blank 3. Thus, at once, the blanks 3 are separated and transferred to the tilter 16 for selective turning, i.e. In one revolution of the crank drive 10, the workpiece 3 is separated and the package of workpiece 3 is delivered, and the carriages 4 and 11 return to their original position (Fig. 6).

0 When the drive is subsequently switched on by the rear fingers of the trolley 6, the next workpiece 3 is separated, and the previous one is transmitted

5 with the front fingers 6 along the rack 1. A package of blanks 3 is then p6, with fingers 12, is fed in a step equal to not less than the width of the face of the blanks (Fig. 7), and then the operations are repeated until all the blanks are transferred

0 on the rack or roller.

The technical advantage of the proposed device is the automatic execution of a sequence of operations for the separation of workpieces for a selective edge without special control devices, but only due to the rotation of the drive crank. This eliminates the need for the operator to participate in the department of blanks and supply them to the tilter. Due to the automatic performance of these operations, the rhythm of the device operation in the rate of rotation of the crank is achieved, therefore

5, the time spent on selectively turning the batch of blanks is reduced, which leads to an increase in the productivity of the device. Device control is only

0 in turning on the turner at the required moment, i.e. extremely simplified.
