Description

one

The invention relates to heat treatment equipment and is intended for quenching tubular products with the aim of their formation.

A known machine for heat treatment of products containing a multi-turn inductor, a product loading mechanism, a cooling unit.

The disadvantage of the known automaton is small; and the productivity.

The aim of the invention is to improve the performance of the machine.

For d. In order to achieve the goal set, the cooling unit is made in the form of a rotor with cooling devices mounted in it, while the rotor has a rotational drive, kinematically connected with the product loading mechanism.

Fig, 1 shows the proposed machine, front view; in fig. 2 - section A-A fkg. li fig, 3 - section bb fkg. 1} in FIG. 4 - top view of the machine.

The machine includes a rotor 1 in which cooling devices 2 are mounted.

The rotor 1 is structurally made of two disks 3 rigidly interconnected with trunnings 4 and 5.

The rotor can be rotated on the shaft 6, rigidly fixed in the housing 7, by a pivotal (lever-ratchet) mechanism 8 connected with a telescopic rod 9 of the mechanism for moving the product.

Through the central and radial openings of the right part of the shaft 6 and the trunnion 5 through the pipelines 1O coolant is supplied to the hydraulic valves 11 of the cooling devices.

Having drilled coolant (when the products are clamped with the sleeves 12 and the hydraulic valves are opened with 11 tons and 13), the inner cavity of the telescopic rods 14, the rods 15, the radial and axial holes of the trunnion 4 and the left part of the shaft 6 are skull.

The air supply to the pneumatic cranes 16 proi:) is led through the non-axial and radial opening of the shaft 6, the radial holes of the journal 4 and the pipelines 17.

From the pneumatic taps 16, air can be supplied via lines 18 and 19 to the left

or the right cavity of the pneumatic cylinders of cooling devices 2.

On the path of movement of the telescopic rod 9, an emphasis 2O is installed, resting against which the quill 21 of the telescopic rod allows the product axis to be aligned with the axis of the cooling device, and also allows the rod 9 of the pneumatic cylinder 22 to move relative to pin 21 of 21 With rod 9, open stop 23 with stop 24 (rigidly fixed, 23) and press the limit switch 25, which switches the pneumatic cylinder to reverse through the pneumatic distributor with electric control.

To load the products, a tray 26 is used, from which, at the command of a time relay with a periodic periodicity, the rod of the pneumatic cylinder 27 serves billets into a multi-seated inductor 28, pushing out the heated billet to the pinny 21 grip.

Products are unloaded before shipment. When the rotor 1 is rotated, the knob of the pneumatic tap 16, resting against the fixed stop, turns, the air is fed into the right cavity of the pneumatic cylinder 2, and the product, released, falls into the container.

The machine works as follows.

After a predetermined period, the time relay is triggered and activates (via an electrically operated pneumatic caulk) a pneumatic cylinder 27, the rod of which feeds the billet from tray 26 into the multi-seat inductor 28 and simultaneously pushes the heated billet into the grip of the quill 21. At the end of the stroke, the rod of the pneumatic cylinder 27 presses the end switch which, through the same pneumozolotnik with electric control, gives it a reverse stroke and simultaneously switches on the second pneumatic spool with electric control, which drives the rod 9 of the pneumatic actuator 22, the mechanism product movement.

four

As the rod 9 moves, the quill 21 rests on the stop 20, and the axis of the workpiece coincides with the axis of the cooling device.

During the further course of the rod 9 relative to the quill 21, the 23 rotates the knob of the pneumatic tap 16 and the product is clamped by the sleeves 12. In its subsequent movement of the ta 23, the abutment 24 presses the limit switch 25, which gives a command through the second pneumatic hammer with the electric control 9 To reverse the telescopic rod 9. During the return stroke of the rod 9, the turning mechanism 8 rotates the rotor (in this case) 1/6 of a turn.

In the process of rotating the rotor, the handle of the pneumatic tap of the cooling device, which moves to its initial position, abuts against the stationary stop and directs the compressed air to the other cavity of pneumatic cylinder 2, releasing the product, which falls into the container, and the cooling device returns to its original position.

The use of the invention will reduce the complexity of the processing process and increase the productivity of labor.
