Description

I The invention relates to the hardening of cylindrical parts with induction heating and can be used for the surface hardening of parts in mechanical engineering.

Known machine for hardening parts, containing a bed, an inductor, a drive carriage with centers and a rotation drive center. .. -.: ..

A disadvantage of the known machine is its low productivity. : The purpose of the invention is to increase productivity by reducing the time for loading, installing and unloading parts;; The goal is achieved by the fact that the automatic machine for hardening cylindrical parts, comprising a bed, an inductor, a drive carriage with centers and a drive

the vra

the center, is equipped with a loading and unloading device in the form of a frame with a portal fixed to the bed, a conveyor placed perpendicular to the frame, an unloading tray and a manipulator installed between them, the carriage - I

mounted on the portal with the possibility of movement relative to the inductor, and one of the centers is made with a clip.

Fig. 1 shows a machine for hardening cylindrical parts with heating an HDTV, general view; figure 2 is the same, a top view; in Fig.Z - section aa in Fig.2; in Fig.4 is a section bB in Fig.2; 5 is an automatic side view with a local section of the installation of the inductor.

The machine consists of a spray inductor

I, loading and unloading device 3, bed 21. The composition of the loading and unloading device includes t frame 2 with a portal

II, conveyor 4, manipulator 5, discharge chute 20. A carriage 12 with a power drive 13 is installed on the portal. Centers are located in the lower part of the carriage, the left center 14 has a rotation drive 15, the right center 16 has a power drive 17 to squeeze the center through the rocker 18, a return spring 19. The conveyor comprises a power drive 6, a rail 7 with stops 8, levers 9, serrated guides 10,

The machine works as follows.

At the beginning of the cycle, the mechanisms are in the initial position: the rail 7 of the conveyor 4 is extended, the grip of the manipulator 5 is lowered, the carriage 12 is in the rightmost position, the right center 16 is depressed.

Quenched parts are superimposed on the end of conveyor 4 with a slide. Using the power drive 6, the rail 7 with stops 8 makes translational movements after a certain period of time. The stops run over the levers 9 and they roll cylindrical parts by piece of the saw rails 10. The levers are balanced so that when the parts are serially filled with the saw rails, the levers do not lower due to the force of gravity of the parts and the stops do not run over them, those. the power cylinder will idle. In the area of the workpiece capture by the manipulator, the conveyor has a component presence sensor. When this sensor is closed, the manipulator 5 captures the part and lifts it into the zone of centers. The power drive 17 of the right cylinder 16 presses the rocker 18 and under the action of the return spring 19, the part is clamped in the centers. The carriage 12, with the help of the drive 13, moves along the portal 11 into the zones of hardening of parts, while the axis of the centers always coincides with the axis of the inductor 1. When the HDTV is heated and the part is cooled with water, the part rotates together with the centers due to the rotation drive 15 of the left center 14. When carriage return in

the initial position, the right center is pushed out and the part falls onto the discharge chute 20, through which it enters the container. Then the cycle is repeated until the parts on the conveyor are finished.

The machine can be integrated into the automatic line, then the parts on the loading device are not superimposed manually, but come from the previous operation. Similarly, the unloading of cylindrical parts is not carried out in containers, but they are delivered to the subsequent operation.

Using the invention will increase the productivity of quenching machines.
