The invention relates to metallurgical production, namely the equipment used to kantowski and stacking of billets.

A device for stacking of billets shown in the drawing NKMZ No. 8-50274.

Part of the stacking device is mounted on the Foundation frame, a vertical guide which is coaxial with the vertical axis is the drive slider. Along the axis of the RAM made a cavity in which is placed a removable insert with a curved inclined surfaces arranged symmetrically relative to the vertical axis. Mentioned curved surface designed to interact with extreme blanks as they move to the top of the pile. Geometrical parameters of removable inserts are the dimensions of the cross-sectional Cantemir of billets. So when working with varietal workpieces, for example, three sizes stacking device equipped with a set of three inserts of appropriate sizes, which are reset when you change the obtained range.

Does stacking device as follows. Prior work included inserts pick up and set in the cavity of the slide box, the dimensions of which correspond to the parameters of billets to be their stacking. Transport roller billets serves four more installed in a line and centered about the axis of the roller conveyor and stop in the area of the stacking device, with the axis of the row of blanks coincides with the axis of the slide insert. Include the lifting drive of the slide, which, moving in a vertical guide frame, picks up the insert to contact her curved surfaces with the last two blanks. As a result of further lifting of the slide and interaction insertion extreme workpiece is moving along a curved trajectory, culminating in the placement of extreme blanks on two medium-sized workpieces, i.e. a stack of four pieces. Then do the binding, stacking and conveyor transport stack further in the direction of the process stream.

It should be noted that since the contact of the curved surfaces of the insertion extreme blanks and before placing the blanks on the top of the pile is the compression of the workpieces along the lateral surfaces of the horizontal components of the forces acting on cantuaria workpiece from the side of the inclined curved surfaces of the insert. In addition, the friction-clutch between the side faces of the workpieces increase in adverse combination of the following factors: high temperatures, is Alicia scale, burrs on the surfaces of the workpieces. Thus, it is necessary to have the lifting drive of the slide from the insert, the intensity of which would allow not only to overcome the weight of the slide bearing insert with the workpiece, and said additional friction-clutch between the side edges of the blanks.

While the disadvantages of analogue should be attributed to the high energy intensity of the drive of the stacking device.

It is also known stacking device according to the patent of Ukraine # 44568 A, B 65 G 57/18 closest structurally to the claimed solution and adopted as a prototype.

The device includes mounted on the Foundation frame, vertical guides which placed the drive slider installed on the vertical axis of the insert. To slide in the upper part of symmetrically relative to the vertical axis of the hinge is attached to a lever with a roller at the free end. The rollers are located with the possibility of contact with the surfaces of copiers that are attached to the frame. In the Central notch of the slide is removable insert with curved surfaces designed to interact with extreme blanks in the formation of the pile. Each of the levers feature an insert with a support, a horizontal platform, which would be affected depending on the transverse RA is Mer Cantemir of billets. The stacking device is fitted with a set of inserts designed to kantowski billets set sizes.

Does the stacking device of billets as follows. Before the start of the pick up device and installed in the Central groove of the slide insert, the geometrical dimensions of which correspond to a cross-sectional sizes of billets to be stacking. In addition, set the horizontal support platform of each lever in the position corresponding to the dimensions of the cross-section of the workpiece.

After the delivery roller of the series of the four blanks and stop him on the axis of the stacking devices include an actuator of the slide, which is moved in its vertical guides. From the moment of contact, supporting the horizontal areas of the levers with the lower surfaces of extreme blanks further movement of the slide is accompanied by a vertical rise of extreme blanks on technologically reasonable height h, as described in the formula, as long as the rollers of each of the levers roll on the vertical surfaces of the respective copiers. After hitting roller levers on sloping plots copiers levers turn on its hinges, and the horizontal platform is removed from the bottom surfaces of extreme blanks (severse the Xia vertical lift blanks). Upon further lifting of the slide come into contact with extreme blanks inclined surface of the insert by moving the latter along a curved path into two motionless lying procurement of the first row, forming a stack of four pieces.

If necessary, binding the stack of blanks weighed over the rollers of the roller conveyor. To produce the tying of the stack, and the return stroke of the RAM, the stack is lowered onto the rollers of the roller conveyor, and the slide insert is returned to its original position.

Compared with similar during stacking of billets on the described device of the displacement at blanks, which is the rise in technological value h calculated by the expression given in the claims, is in a free rise without effort compression between the side faces, which leads to the exclusion of efforts friction-clutch between the side faces of the workpieces during vertical ascent and entails reduce energy costs spent on the implementation of the set, and reducing the intensity of the stacking device as a whole.

However, with varietal workpieces with different parameters of the cross-section, for example 120×120, 130×130, 140×140, etc. necessary to complete the device multiple inserts, dimensions are about Machaut size anthemic blanks. The number of inserts is determined by the number of sizes of stackable varieties.
