Description

; The invention relates to heat treatment of parts, e.g. hardening d & hoists by moving them into the cool; necks of liquid with heating in a protective atmosphere in furnaces equipped at the outlet with the air trap. It is known that a device for hardening parts, containing a furnace, a quenching tank, a mechanism for moving parts of cooling fluid and a mechanism for transferring parts from the furnace to the tank. Both mechanisms are mounted on a common carriage, variable; above the quenching tank along horizontal guides to remove the device from the hydraulic seal without depressurizing the lechi. However, in such a device, it is possible to grumble, either by wiggling or turning. -, gsheniem. ; The transition from one quenching method to another requires the replacement of the entire quenching device, which limits the possibility of choosing the optimal method for parts of different nomenclature. In addition, this device requires a quenching tank of increased depth, which makes it impossible to use it in combination with hearth hardening tanks. In order to expand the field of application: in the proposed device, the jnepe- mechanism, parts of the furnace from the furnace to the tank, is made in the form of rotary cantilever arms that carry the table and the stops for holding the parts, and the axis of rotation of the levers is located relative to the hydraulic lock from the side oven, table and stops are made. with the company of arms relative to the levers, and the carriage, mounted on the horizontal directions 1f “shih, sweaty lifting, in the vertical direction - pull it out of the hardening: tank. In order to lift the carriage in the vertical direction, its horizontal directions are elevated and equipped with elevators on the i ends. In this case, the mechanism I of movement can be made in the form of j, an interchangeable block, comprising a hydraulic fluid, a device for holding parts and a working member — rolls for swinging the swing table. | In order to transfer parts to the table for t rocking, the table and the stop of the transceiver mechanism .ca can be equipped with a rotational drive in the form of two coaxial cams connected to the entire cylinder 1 and turning the TABLE and stops at the corners required by dp non-delivery of parts

FIG. 1 shows the proposed mouth. Soldering with a mechanism for rotating parts; in fig. 2 then e, with a mechanism for locating parts; fig 3 - mechanic of parts rotation with pressure rollers for dressing parts; FIG. 4 is a section along A-A in FIG. 3; in fig. 5 device, in the position of withdrawal from the quenching tank. The quenching device is installed at the entrance of the procuring quenching furnace 1.. of continuous operation, equipped with a hydraulic lock 2 at the exit, the lower edge of the cat (which is immersed in the cooling fluid of the conveyor hardening tank 3, the Furnace works with a protective atmosphere and is equipped with;; an automatic hitch mechanism, for example, a roller table mechanism,

; The quenching device contains two horizontal octal guides 4 and two horizontal fixed guides 5. Guides 4 are connected to each other, with other crossbars 6, At each corner of the lifting frame formed by the guide lines 4 and crossbars 6, T1 is a recessed screw elevator 7 Electrodvig, gateli all. Four lifts act synchronously. On tracks 4 and 5, a carriage is mixed, consisting of a frame 8 and carrying rollers 9.-. Carriage connected tse. n i 10 with a drive displacement 1.1. On. carriage mounted mechanbii, transfer, parts from the furnace to the tank, The mechanism contains. roller table 12 mounted on rotary cantilevered G.-shaped levers 13. The levers are mounted on the shaft 14 connected to the power cylinder 15. The shaft 14 and the cylinder 15 are fixed on the frame 8, the carriage. Ia levers 13 mounted power cylinder 16.

Table 12 is made in two versions.

During the hardening of parts by rotation, the table is rigidly attached to the levers 13 and supplied with fixed stops, 17 and a swivel support 18. The stop is mounted on the lever 19, the axis of which is connected by a crank and TSS / Go with the shaft of the power cishshdr 16. . 12 is pivoted with respect to the levers 13 and is mounted on the axis 20. The table of the women is fixed with a stop 21 and pivot stops 22, also seated on the axis 2O. On chr 13, the swiveling cams 24 and 25, which are mounted on the axis 23, are connected to the props of the power Z. pshindra 16.,

The cam 24 interacts with the rotation of 1 table 12, and the cam; 25 with a swivel support 22. On the frame 8 of the carriage, the mechanism for moving parts in | quench tank This mechanism is made in the form of an interchangeable block and has two basic versions: for rotating parts and showing their dp. The mechanism for rotating parts contains a few pairs of rollers 26 connected through a system, gears with drive 27, and a rotary / valve 28 connected to the sylly cylinder 29. Mechanism-flow no-j kachivavi details contains fron 30, installed. new in the guides 31. The table is said to be: reciprocating. from a rotating cam 32 connected through a gear system with a drive 27. The CTOJ is equipped with a turning stop ZZ, connected to one with the power cylinder 34. The mechanism; for rotating parts may be equipped with a device for straightening parts, which; Roy contains pinch rollers 35 with flanges; sitting on levers 36, connected

with power cylinders, 37.

The device works as follows.

The heated parts 38 arrive at the table 12. For the hardening variant of the method of rotation, the details on the table come in stacks. The levers 13 are rotated to the bottom position, depicted by a dash line. When | This part is held on the table: from-to-j j with the power of the stops 17 and 18 or 21 and 22. Stops | 18 and 21 are height adjustable above the table. .. j

at the end of the rotation of the levers 13 down part-j, they are mounted on rotating rollers; 26 and begin to rotate. With this emphasis

; 17 passes between the rollers. The rest time 18 is raised through retraction time, and the parts

. 38 move along the rolls (the shutter 28 where they continue to rotate. The movement of parts along the rolls 26 is due to the fact that the rolls are inclined to some.

: angle to horizontal. .

Then the levers 13 are raised, the table 12 and the support 18 are folded to their original position, and new parts arrive at the table from the oven, which are then lowered onto the rolls 26. After a predetermined time, the valve 28 rises.

.: it is damaged, the parts are scaled with a roll and fall onto the conveyor 39 of the quenching tank, after the closure 28 is lowered, then the stop 18 is lifted, the details are fed through the rolls to the flap 28, etc.

When quenching by rotation with adjustments to the parts, after their approach to the flap 28, the pressure rollers 35 are brought in, after which the flap 28 rises and de.

The hoists are held by the flanges of the rollers 35. The rotating parts are clamped between the L | 23 and the rollers 35, thereby correcting the parts. After the rollers 35 are lifted, the parts slide off the rollers 26. I Adjust the position of the rollers 35 to different diameters of the hardened parts by moving along the guide rails of the 40 brackets 41. j When hardened using the rocking arm at the turn of the levers 13 down power qi i pindr 16 rotates clockwise; ke cams 24 and 25 ,. As a result, the table 12 and the stop 22 turn counterclockwise. The surface of the table 12 is set to pair the table surface I 30. The stop 22 rotates at a smaller angle than the table 12, as a result of which the stop is recessed below the table surface 12. Sa descends on table 30 and swings on. held by the anvil 33. After a predetermined time, the anvil 33 rotates, and; parts are dropped onto conveyor 39. D & -. j the next cycle is repeated.

j. The withdrawal of the device from the tank without the furnace being activated is carried out as follows. The levers 13 are lowered to the lower position, after which the actuator 11 moves the carriage to the right. With this, the table is 12 hours and the stop il8 also occupies its lower positions. Then the lifts 7 raise the guides 4 upwards until all the mechanisms of the tank are completely out of the tank.
