The device comprises a horizontal rail 2 for loading parts into the furnace 9, a vertical sub-rail rail 4, a flexible connection made in the form. a separate closed circuit 6 connected to the actuator 7, and the valve. The vertical rail 4 is connected to the horizontal rail 2 by means of gears 20, 21 and 22, and the end of the rail 4 is in contact with a stop 32 fixed on the side surface of the flap. In addition, a bracket 33 is mounted on the flap along its width so that the lower end of the flap and the lower end of the bracket are installed at the same level. On a closed loop 6, con fi jers 25 are mounted on one axis in contact with the bottom ends of the flap and bracket 33, while circuit 6 is filled with irreversible and has vertical 26, horizontal-27 and inclined 28 sections.

2, depending on the size, configuration and weight of the parts, is fastened with clamps of various designs and dimensions.

In the initial position, before loading, the heating furnace is closed by a flap 8, which is in its lowest position and rests on

1 shows a device of the area of 14 ribs 12 and 13, loading and unloading parts from a heating furnace, front view} in FIG. 2, view A in FIG. 1; on fig.Z - I section in figure 1.

I The device includes a housing 1, a 5 5 water horizontal rail 2 installed in a guide 3, a vertical i rail 4 fixed in support 5,; flexible connection J made in the form of ot-;, efficient closed loop 6, connected to the actuator 7, and the valve 8 on; heating furnace 9.. Case 1 is welded and made; IT from base 10, walls 11, ribs 12 and 13, having platforms 14, To the base 10, lugs 15 are welded, and driven sprockets 16 and rollers 17 are mounted on walls 11.

The vertical rail 4 is provided with a spring 18 to the adjusting nuts and is connected to the horizontal rail 2 by means of gears 20, 21 and 22,

Closed loop 6 is made non-reversing and mounted on driven sprockets 16, rollers 17 and leading 35 sprocket 23 mounted on actuator 7, while rollers 25 are fixed to it on console 24 on one axis. In addition, contzF b has a vertex rail 2 on some the distance from the furnace 3, the rollers 25 of the flexible contour — on the inclined section 2, the drive 7 is turned off, and the vertical rail 4, which has compressed the spring, is stopped downward due to contact with the stop 32.

In this position, the tong (not shown) of the horizontal rail 2 is loaded with a part,

When the actuator 7 is turned on, the rollers 25 moving together with the flexible contour exit to the vertical section 26 and interact with the lower end 34 of the valve 8 and the lower end 35 of the bracket 32. With further movement, the rollers 25 raise the valve 8 to the horizontal section 27,

During the movement of the rollers 25 along the horizontal section 27, the shutter 8 is in its extreme upper position and stationary due to the fact that the horizontal direction of movement of the rollers 25 coincides with the horizontal position of the bottom of the slab and the bracket, while the heating furnace 9 is open and between the vertical bar 4 and focus 32 is formed

kalnye.26 and horizontal 27 area-40 ° P

Continuing the movement of the rollers 25, the coping configuration of the flexible contour, moves to the initial position n opposite to the vertical 26 and inclined 28 sections, which ensures the downward movement of the valve by the action of its own weight before contact with the sites of 14 edges

ki corresponding to the outer contour of the valve, and inclined sections 28,

The actuator 7 is mounted on racks 29 with the possibility of movement with fixing the extreme position by means of a push-pull volume 30,

The flap 8 has guide rollers 31, an abutment 32 fixed on its side surface, lateral 33, located along the width of the flap, while the lower end 34 of the flap 8 and the lower end 35 of the bracket 32 are flush. The stop 32 is periodically in contact with the upper end 36 of the ver-i ticker rail 4.

The device works in the following way.

For loading and unloading the heating furnace 9 to the horizontal bar 2 - at some distance from the furnace 3, the rollers 25 of the flexible circuit - on the inclined section 28, the actuator 7 is turned off, and the vertical bar 4 that has squeezed the spring is stopped down due to contact with the stop 32.

In this position, the tong (not shown) of the horizontal rail 2 is loaded with a part,

When the actuator 7 is turned on, the rollers 25 move along with the flexible contour to the vertical section 26 and interact with the lower end 34 of the valve 8 and the lower end 35 of the bracket 32. When moving further, the rollers 25 raise the valve 8 to the horizontal section 27,

During the movement of the rollers 25 in the horizontal section 27, the flap 8 is in its extreme upper position and stationary due to the fact that the horizontal direction of movement of the rollers 25 coincides with the horizontal position of the bottom of the flap and bracket, while the heating furnace 9 is open and between the vertical rail 4 and the stop 32 formed

° P

Continuing the movement of the rollers 25, a copy of the configuration of the flexible contour, they move to their original position in the opposite vertical 26 and inclined 28 sections, which ensures that the damper moves downward under the action of its own weight until it comes into contact with the sites of 14 ribs

12 and 13.

I

While raising the flap, the tong and the part move in the direction of the heating furnace 9 due to the upward movement of the vertical rail 4 under the action of the compressed spring 18.

The movement of the rail 4 is the result of raising the stop 32 with the flap 8.

The vertical movement of the rail 4 is converted into an increased horizontal movement of the rail 2,

which, when lifted to the appropriate height of the flap 8, grip a part into the heating furnace.

During the stop of the valve 8 in the extreme upper position of the tong of the horizontal rail 2, at the command of the corresponding sensor, it cuts out and the part rests on the pitch below (not shown) of the heating furnace 9, with which it is transported deep into the furnace.

Due to the downward movement of the rail 4 under the action of the lowering stop 32 when the valve 8 is moved downward, the spring is compressed and the horizontal rail 2 returns to its original position,.

The unloading of the heating furnace 9 is carried out in a similar way, with the heated part of the furnace moving the piece to the setting of the rail 2.

The proposed device ensures reliable operation, since there is no need to stop the drive, when changing the direction of movement of the valve,
