Closest to the proposed technical solution is the line of heat treatment and stamping of parts, including equipment similar to the proposed device.

The line consists of a receiving rack 1, a heating furnace 2, a rotary loading machine 3 moving along rail tracks laid along the front of the furnace 2 and a rack 1, a receiving roller table 4 located along the longitudinal axis of the press 5, a receiving table 6 located along the same axis on the other side of the press 5, the loading device 7, moving along rail tracks laid along the receiving roller table 4, the stamp of the press 5, the receiving table 6. For an exact stop at the positions of the loading device 7 is equipped with a retractable stop. At the same time, the receiving roller table 4 has drive transverse rollers 9, driving tracks 10 for extending the cradle of the rotary loading machine 3 and a transverse beam 11 that can be moved and fixed along the frame of the roller table (SU, AS 1130727, F 27 D 3 / 00, 1983).

This line is mainly used in thermopress production when it is necessary to reduce the time for transferring heated heated billets from the heating furnace to the press die, which is especially important during subsequent quenching of stamped parts from stamping heating. It also allows you to completely eliminate the manual centering of the heated workpieces in the stamp.

A disadvantage of the known line is the unstable quality of sheet metal parts subjected to stamping and hardening from stamping heating, arising due to the relatively increased transfer time caused by the sequence of operations of transferring the workpiece by the rotary loading machine from the furnace to the roller table, operations to center the workpiece by the transverse beam of the roller table, and grippers of the loading devices and operations for transferring a workpiece by a loading device from a rolling table to a stamp.

in addition, due to the location of the roller table and the receiving table on both sides of the press, it is difficult to change stamps on the press.

The problem that this utility model is aimed at is to create a loading device that allows the fast transfer of sheet-metal parts from the heating furnace to the press die, as well as providing convenient press maintenance.

The technical result that will be achieved by using this utility model will improve the quality of thin-sheet parts subjected to hardening from stamping heating and facilitate operations associated with changing stamps on the press.

The technical result is achieved by the fact that in the boot device, mainly for thermopress production, including the boot and cage carriage, the swing frame, the swing frame is equipped with guides mounted parallel to its longitudinal axis, and the load carriage is placed on them to move along them into the press working area In addition, rollers of the roller table mounted perpendicularly to its longitudinal axis and made with the possibility of passing through them a cage weave. Moreover, the roller table is equipped with an adjustable transverse emphasis.

The essence of the utility model lies in the constructive implementation of the boot device.

This design of the loading device allows you to combine the transfer and centering of the workpiece, which reduces the total time for transferring the workpiece from the heating furnace to the press die, and after the loading device leaves the press, there is free space around it allowing convenient change of dies on the press.

in FIG. 7 - a device (option) with a movable loading carriage, extended into the area of the working space of the press.

The loading device consists of a frame 1 mounted on it of a rotary frame 2. On the rotary frame 2 there are driven rollers of the roller table 3 so that their axes are perpendicular to the longitudinal axis 4 of the rotary frame 2, adjustable transverse stops 5 with the possibility of their movement and fixing along the rotary axis 4 frames 2. It also has guides 6 parallel to its longitudinal axis 4, on which the loading carriage 7 is located. Between the rollers of the rolling table 3 on the pivoting frame, there are driving tracks 8 in which the charging carriage is located a 9.

The loading carriage 7 is equipped with grippers 10, which with their drives located on the carriage 7, can make transverse relative to the longitudinal axis 4 of the rotary frame 2 and vertical relative to the rolling table 3 movement.

The cradle 9 is equipped with a lifting-lowering mechanism 11, made, for example, in the form of a hinged parallelogram.

The movement of the boot carriage 7 along the guides 6 is limited by the stops 12 and 13.

Moreover, to move heavy workpieces, it is advisable to run guides 6 in two parts and place them on the rotary frame 2 and on the press die to reduce the metal consumption of the loading device (Fig. 6), and for moving light workpieces, the loading carriage 7 can be suspended (Fig. 7 ), fixing the guides 6 on the racks 14 of the swing frame 2.

For blanks 15, a rack 16 is provided, a heating furnace 17 with a rail track 18, while the rack 16 is equipped with driving tracks 19, and under the heating furnace 17, driving tracks 20.

The device is equipped with a stamp 21 of the press 22, where special grooves 23 are provided for contact with the grippers 10.

In addition, the device includes a tempering furnace 24 and a rack 25 for stamped parts.

The utility model is as follows.

The workpiece 15 is placed on the rack 16, on which the cage is formed on the entire working area of the hearth of the heating furnace 17. In this case, the cage can be composed of several blanks 15. The loading device moves along its rail 18 to the rack 16, while the frame 1 stops in position , in which the cradle 9 from the rotary frame 2 can move to the rack 16, equipped with driveways 19.

The cradle 9 extends onto the rack 16 and, using its lifting-lowering mechanism 11, removes the workpiece 15 from the rack 16. After that, the cradle returns to its original position on the swing frame 2, and the charging device moves to one of the heating furnaces 17. The cradle 9 extends into the heating furnace 17, leaves the workpiece 15 on the bottom of the heating furnace 17, equipped with drive tracks 20, and returns to its original position on the swing frame 2. After heating the workpiece 15, the cradle 9 Recreate put forward

the heating furnace 17 to the desired size and the lifting mechanism 11 removes one of the closest workpiece from the hearth of the heating furnace 17, and then returns to its original position on the swing frame 2, where it puts the workpiece 15 on the rotating rollers of the roller table 3. The workpiece 15 by the rollers of the roller table 3 moves to the stops 5 of the rotary frame 2, while also its transverse centering is performed due to the lateral displacement of the grippers 10 of the loading carriage 7, moving between the rollers of the roller table 3. Then the workpiece rises 10 from the rollers of the roller table 3. The final transverse position of the grippers 10 and the position of the stops 5 on the rotary frame 2 is pre-adjusted depending on the desired position of the workpiece on the die matrix 21 of the press 22, taking into account the fixed position of the frame 1 relative to the press 22 and the movement of the boot carriage 7 from the stop 12 all the way to 13.

During the movement of the workpiece along the rolling table 3, its transverse centering and lifting of the grippers 10, the frame 1 is moved to the press 22 and the rotary frame 2 is rotated towards the press 22, which reduces the total transfer time of the workpiece from the heating furnace 17 to the stamp 21 of the press 22 in comparison with the prototype. After stopping the frame 1 and the rotary frame 2, the loading carriage 7 with the workpiece 15 along the guides 6 moves to the stop 13, and then with its grips 10 lowers the workpiece 15 onto the die matrix 21 of the press 22. The grippers 10 enter into special grooves 23 of the die 21, and the workpiece 15 remains to lie on the mirror of the stamp 21.

Then the grippers 10 are parted, the loading carriage 7 is moved to the rotary frame 2 in its original position until it stops 12.

The workpiece 15 is stamped or stamped, combined with hardening, depending on the design of the stamp 21.

21, and lifts the grippers 10 together with the stamped part, and then returns to its original position on the swing frame 2 to the stop 12, where it lowers its grips 10, spreading them to the extreme positions and leaving the stamped part on the rollers of the roller table 3, from which the part rises the lifting-lowering mechanism 11 of the cradle 9.

After that, the boot device, at the choice of the operator managing it, moves to the tempering furnace 24, if the stamping was combined with hardening, or to the rack 25, where the stamped part is placed using the cradle 9.

The non-hardened stamped part by a crane (not shown in the figures) is transferred from the rack 25 to the quenching tank 26.

This completes the work cycle.
