Residual Water Removal Device after Hardening

The present invention relates to a device for removing residual water after quenching, in particular, a flatness state during forced cooling of the product by cooling water sprayed from a roller quench installed on a roller table when the product is extracted after heating to a proper temperature in a heat treatment furnace. Residual water removal device after quenching to remove the residual water accumulated on the upper surface of the defective product by attaching the product to the magnet by using the air cylinder at the lower part of the roller table (TABLE PIT). It is about.

Conventionally, the product which is hardened (quenched, quenched) in the hardening apparatus and discharged is discharged in the state seated by the roller table 5 provided in the rear side of the hardening apparatus 1, as shown in FIG. It is transferred to the aftertreatment process.

In addition, the support 6, 6 'is mounted on both sides of the upper surface of the roller table 5, the air spraying device (AIR SPRAY, 2) is mounted on the upper side of the support 6, 6', The residual water 4 remaining in the concave (aka gourd) product upper surface 3 discharged to the roller table 5 through the air pumped from the air was blown out.

However, since the residual water 4 accumulated in the concave shape of the upper surface of the product 3 passes through the air spraying device 2 without being completely removed by the air pressure injected from the air spraying device 2, the upper surface of the product As oxygen contained in the residual water (3) in (3) is combined with iron, the scale generation speed is rapidly increased, and in particular, the portion where residual water is present on the surface of the product after TEMPERING has a problem of staining.

In addition, when transporting the finished product to the magnet crane, residual water 4 falls on the motor brake liner due to vibration of the crane running rail, and slip occurs when driving the roller table. Water causes hydrolysis, which causes moisture and foreign substances to get caught in the UV sensor glass, causing the burner to be extinguished, and it is pointed out as a problem in productivity and quality deterioration due to burner digestion.

Accordingly, the present invention is devised to solve the conventional problems as described above, the purpose of the present invention is to eliminate the residual water on the upper surface of the product after hardening to prevent stains caused by the scale generated on the surface of the product. It is to provide a residual water removal apparatus after quenching.

Another object of the present invention is to completely remove the residual water on the upper surface of the product after quenching and to prevent foreign matters from being caught on the UV sensor due to the evaporation of the residual water during the soaking operation. It is to provide a residual water removal apparatus after quenching to increase productivity and prevent quality deterioration.

Receives the detection signal output from the limit switch 16 and the product detection sensor 13, and outputs an operation signal to the solenoid valves 20a, 20b, and 20 ', thereby raising and lowering the air cylinders 14, 14' and horizontal air. It is composed of a control unit for operating the cylinder rod of the cylinder (26, 26 ').

Hereinafter, the operation and effects of the present invention will be described.

First, the apparatus of the present invention raises the entire base plate 23 by the air cylinders 14 and 14 'operated inside the frame 21 installed in the lower portion of the roller table 5 to the magnet 9. As the built-in product detection sensor 13 detects the product 3, the magnet 9 attaches the product 3 by its magnetic force.

At this time, the control unit (not shown) controls the solenoid valves 20a and 20b for opening and closing the flow path of the air line 19 of the lifting air cylinders 14 and 14 ', that is, the lifting air cylinders 14 and 14'. By supplying different pneumatic pressure to each other, by varying the left and right height of the base plate 23, the product is inclined to remove the residual water (4) accumulated on the upper surface of the product (3).

Of course, it is also possible to tilt the base plate 23 by mounting two different solenoid valves 20a and 20b in the air line 19, but by using different capacities of the lifting air cylinders 14 and 14 'as the base. The plate 23 may also be tilted.

And, the control unit is built in a control box (not shown) installed at a certain distance away from the roller table 5, each sensor and the driving device is connected by wire or the like to send and receive signals.

As shown in FIG. 2, the base plate 23 is hingedly coupled (not shown) to the rod ends of the lifting air cylinders 14 and 14 'and travels on the upper surface of the base plate 23. As shown in FIG. The rail 11 and the cable bearing 12 are formed, and the magnet 9 reciprocates along the running rail 11 by the traveling wheel 10 attached to the bottom surface thereof.

Of course, in the device of the present invention, although not shown, a motor for generating rotational power is attached to the bottom or other portion of the magnet 9 to receive the electric power supplied through the cable bearing 12 to provide the rotational power. Can be.

4 is a structural diagram showing the structure of an air injector according to the present invention.

The air spraying device 12 according to the present invention comprises a pair of horizontal air cylinders 26, 26 ′ mounted on the roller table 5 in a width direction perpendicular to the conveying direction of the product. It is attached to the cylinder rods 27 and 27 '.

A plurality of air injection nozzles 121 are provided at the front portion of the air injection device 12 at regular intervals, and the air is injected through the nozzles. The air injector 12 receives air in the opening process of the solenoid valve 20 ′ provided in the rubber hose 18. That is, an air compressor such as an air compressor is connected to the solenoid valve 20 '.

Therefore, when the product detection sensor 13 installed in the magnet 9 detects a product and inputs a detection signal to the control unit, the control unit supplies air pressure to the horizontal air cylinders 26 and 26 'so that the air injection device 12 is supplied. It proceeds across the top of the product 3.

Since the air is continuously injected from the plurality of nozzles 121 provided in the air injector 12 while the air injector 12 crosses the upper surface of the product 3, residual water accumulated on the upper surface of the product 3 is accumulated. (4) is blown out.

Of course, since the base plate 23 is inclined in one direction during the operation of the lifting cylinders 14 and 14 ', the residual water accumulated on the upper surface of the product 3 flows by its own weight while the air spraying device 12 Is quickly removed by blowing air.

At this time, when the air spraying device 12 continues to move forward to the forward limit switch 16 installed on the working side 8, the forward limiting is performed by the touch bar 25 "attached to the control spraying device 12. The switch 16 is switched to output a switching signal to the controller.

The control unit, which receives the switching signal from the forward limit switch 16, reverses the horizontal air cylinders 26 and 26 'to reverse the air injection device 12.

After the hardening, the product 3 discharged along the roller table 5 is attached to the magnet 9 at the lower part of the roller table 5, and then the lifting air cylinder 14 is installed at the lower part of the roller table 5. 14 ') is inclined to the product 3, and then the residual water accumulated on the upper surface of the product is completely removed by using the air spraying device 12 installed on the driving side 7.

As described above, according to the present invention, the burner is extinguished by the incomplete operation of the UV sensor by preventing the foreign matter from being caught in the UV sensor by completely removing residual water on the upper surface of the product after quenching. To increase productivity and prevent degradation of quality.
