This invention relates to the mechanization of heat treatment processes, and to the loading of blanks into heating furnaces. A device for loading the heating furnace is known, which contains a hydraulic cylinder, a carriage with an emphasis and guides. The carriage is made of interlocked cases of two plunger hydraulic cylinders, on which running rollers are installed with the ability to move 1 | W into the ends of which abut the plungers of hydraulic cylinders with their shoes 111. However, in the device of such a Design with increasing length of movement it is necessary to increase the rod travel, increase the length of the rods, reducing their stability and thereby reducing the reliability of the drive. Closest to the invention to the technical essence is a device for loading a heating furnace, comprising a frame, a carriage mounted on a frame with a reciprocating drive, -,. a bar with a tray and a copier device in the form of a copier guide and a copier roller. Rods are installed in the bearings of the barquet with the possibility of turning. At one end of each hose there are shanks with rollers in contact with; slats, and on the other - the tray. The device is provided with a blank cassette and a pusher with a restrictive line, the pusher and the ruler being connected to the carriage 2}. The disadvantages of the known device are the large overall dimensions along the length and the large stroke of the reciprocating movement, which leads to a decrease in the reliability of the operation of the device. The purpose of the invention is to increase the reliability of the device. This goal is achieved by the fact that in a device for loading a heating furnace, comprising a frame, a carriage with a reciprocating drive, a rod with a tray and a copier in the form of a copier and a copier roller mounted on the frame, the actuator is made in the form of sequentially connected hydraulic cylinders forward and reverse strokes by means of a flexible connection, which covers the rods of the cylinder head 1 6 rotsnlinder, and its ends are rigidly fixed on the frame, while the rod of the hydraulic cylinder of the forward stroke is rigidly connected with the carriage , the bar with the tray is rigidly fixed on the flexible connection of the hydraulic cylinder of the forward stroke, the copier. The guide is made in the form of a groove on the rod, and the copier roller is placed on the carriage. Figure 1 shows the proposed device, a kinematic scheme; Fig. 2 is a diagram of the movement of the tray. . On the frame 1 there is mounted a one-sided power cylinder 2, the rod of which has a block 3, one-way power driver 4, the rod of which is fixed on the carriage S. Tray 9 is fixed on rod 6, designed for harvesting 10, as well as blocks P and flexible element 12. Flexible element 12 is fixed at point A on the base frame, bends the carriage unit, and the second end is fixed on rod b at point B The device works in the following way. When loading the workpiece 10 into the furnace, the carriage 5 is moved by the rod of the cylinder cylinder 4 and the flexible element 12 moves the rod b at double speed. At the end of the movement, the finger with the roller 8, interacting with the copy groove 7, rotates the bar-GU, and with it the tray 9. The bar is rotated due to the interaction of the copy-groove provided on the bar and the finger with the roller, performed on the cross carriage. The drive moves the carriage, and due to the flexible coupling, the rod moves relative to the carriage. The speed of movement of the carriage 5 is equal to the speed of the stroke of the power cylinder 4, and the speed of movement of the rod b due to the flexible element 12 p is twice as large. After completion of the unloading process of the workpiece 10, the stem of the power cylinder 2 is brought to its initial position by the action of a flexible element. When the working medium is supplied to the power cylinder 2, the device returns to its original position. The use of the proposed device for loading blanks pos. 11359864

This leads to an increase in the reliability of the device; an increase in the stroke of the rod in comparison with the simplification of the design with the course of the force of the drive by two-fold.

A DEVICE FOR LOADING A HEATING FURNACE, containing a frame, a device in the form of a copy guide and a copy roller, characterized in that, in order to increase the reliability of the device, the drive is made in the form of series-connected forward and reverse hydraulic cylinders by means of a flexible connection that covers the rods hydraulic cylinders, and its ends are rigidly fixed to the frame, while the rod of the forward cylinder is rigidly connected to the carriage, the rod with the tray is rigidly fixed to the flexible connection of the forward cylinder, the stem a carriage with a reciprocating drive mounted on the frame, a rod with a tray and a copy guide is made in the form of a groove on the rod, and the copy roller is placed on the carriage. ι £ / n with SP ¢ 0 00 C IQ 2 cylinders, and its ends are rigidly fixed to the frame, while the rod of the forward cylinder is rigidly connected to the carriage, the rod with the tray is rigidly fixed to the flexible connection of the forward cylinder, the copy path. The guide is made in the form of a groove on the rod, and the copy roller is placed on the carriage . . Figure 1 shows the proposed device, a kinematic diagram; Fig. 2 is a diagram of the movement of the tray. A single-acting actuating cylinder 2 is mounted on the frame 1, the rod of which has a block 3, a single-acting actuating cylinder 4, the rod of which is fixed to the carriage 5. The carriage is equipped with guides for the rod 6, made with a copy groove 7, and has a finger with a roller 8. Tray 9 is fixed on the rod 6, designed for the blanks 10, as well as the blocks 11 and the flexible element 12. The flexible element 12 is fixed at point A on a fixed frame, bends the carriage block, and the second end is fixed on the rod 6 at point B. 1' The device operates as follows. When loading the workpiece 10 into the oven, the carriage 5 is moved by the rod of the power cylinder 4 and the flexible element 12 moves the rod 6 with double speed. At the end of the movement, the finger with the roller 8 interacts with the copy groove 7 gu 6, and the rotation of the rod is carried out due to the interaction of the copy groove provided for on the bar, and the finger, with a roller made on the carriage. The drive moves the carriage, and due to the flexible connection, the rod moves relative to the carriage. The speed of movement of the carriage 5 is equal to the speed of the rod of the power cylinder 4, and the speed of movement of the rod 6 due to the flexible element 12 is twice as much. After the process of unloading the workpiece 10, the rod of the power cylinder 2 is brought to its original position under the action of a flexible element.
