HANGING DEVICE RING, containing tank, water lock, table with platform, mechanisms for lifting, lowering, swinging and unloading the table, is different in that it is pivotally installed to increase productivity. The frame with interchangeable fenders fi installed on the edge of the platform, and the unloading mechanism is designed as installed oppositely on the side walls of the hydraulic lock and tank at different levels of the sliding stop and swivel bracket, respectively interacting with the frame and platform. . ,

Description

i The invention relates to heat treatment and can be used in the metallurgical, machine-building industry. A device for hardening rings, containing a frame with a carriage and a table, a mechanism for moving fn, are known. The disadvantages of the device include the possibility of rings falling from the steel due to its swinging, as well as the complexity of the design. The closest to the invention to the technical essence is a device for hardening rings, containing a tank, a water seal, a table with a platform, lifting mechanisms, tumbles, wiggling and unloading costs. 2. The disadvantages of the known device are the complexity of the design and low productivity rings in racks. The purpose of the invention is to increase productivity. The goal is achieved by the fact that a device for hardening rings, containing a tank, a hydraulic lock table with a platform, mechanisms for raising, lowering, swinging and unloading the table, is equipped with a frame with interchangeable stoppers installed at the edge of the platform. on the side walls of the hydraulic lock and the tank at different levels of the sliding stop and swivel bracket, respectively interacting with the frame and the platform. FIG. 1 shows a front view of the device in FIG. 2 - the same, side view j in FIG. 3 and 4 - a platform table and a turning frame, side view; in fig. 5 and 6 - turnable frame with stops. The device contains a tank 1, a hydraulic shutter 2, a mechanism for lifting, lowering and swinging into the form of a two-post frame 3 of a pneumatic cylinder 4 with a stem 5, rocker arms 6, an air motor 7, a carriage 8 with a bracket 9, a base stand 10 and a Tli table mounted on the carriage 8, the loading mechanism in the form of a mechanical arm for feeding the rings to a hardening table (not shown). 92 On the table 11, a platform 12 is installed, having two open pivot bearings: the left 13 and the right 14, and a swinging frame 15 with interchangeable stops 16 mounted on it. The unloading mechanism is filled in the form of a pneumatic cylinder 5 mounted on the hydraulic lock 3 of the sliding stop 17 and located on the tank 1 swivel bracket 18. The device operates as follows. The rings stacked are loaded onto platform 12 all the way into stopper 16, the parts being pinched between two legs of limiter 16. Then pneumatic cylinder 7 is released by means of the rocker arm 6, but pneumatic motor 7 is connected to the carriage 8 through the rigidly fixed bracket 9, the carriage 8 is also lowered. Thus, after loading the rings on the table 11, the latter is lowered by the pneumatic cylinder 5 together with the rings into the quenching medium. After the table 11 is lowered into the quenching medium, the air motor 7 is turned on, which, after reciprocating the piston, shakes the table 11 in the quenching medium. When the table is rotated, a swing in the horizontal plane of the stack of rings occurs due to its own weight and due to the stopper on which the entire stack of rings rests, maintain a stable position. At the end of the quenching time, the time relay is activated and the air motor 7 is switched off. Wherein . the air motor piston stops in the upper rest position. Next, the pneumatic cylinder 5 raises the air motor 7, and with it the carriage with the working table in the upper position. Then the stop 17 is rotated and the bracket 18 is rotated. When the table 11 is lowered by the pneumatic cylinder 5, the swing frame 15 first rises, resting on the stop 17, then the platform 12 rises, leaning on the bracket 18. --. The rings are unloaded on the quenching tank conveyor 1 (not shown). After unloading the rings, table 11 rises back to the original polo;

living At the same time, the platform 12 with the frame 15, mounted on the supports 13 14 with a slope towards the unloading side, the stops of the hydraulic lock 3 rotates around the support 13 to a horizontal position in the initial position.

by increasing the swinging speed.

The use of a rotating frame with interchangeable limiters in the device, as well as a full stop and interchangeable limiter, allows increasing the throughput of the quenching tank due to the possibility of hardening the stacks of rings, which ultimately leads to an increase in the production capacity of the device itself.
