INVENTION The present invention relates, for example, liquid level adjusting with apparatus used to apply the lubricant to the forging work
The present invention relates to a lubricant applying device .

[0002]

2. Description of the Related Art In general, a work for warm forging is often sent to a press device after a graphite-based lubricant is applied to the surface thereof, and therefore, a lubricant (liquid) is stored in a supply line of the work. A tank is provided, and the lubricant is automatically applied by the work passing over the transport chute immersed in the storage tank.

FIG. 4 schematically shows a work supply line for such a warm forging. Reference numeral 1 denotes a parts feeder for arranging the discharged round bar-shaped works 2 in a line and discharging them.
Is a belt conveyor for transporting the work 2 discharged from the parts feeder 1, and 4 is a heating device for heating the work 2 fed by the belt conveyor 3 to a predetermined temperature.

[0004] in front of the heating device 4, a lubricant reservoir 6 it stores lubricating agent 5 of graphite diluted to a predetermined concentration is provided by water.

[0005] In the lubricant storage tank 6, an intermediate portion is bent substantially in a U-shape, and the lubricant 5 is introduced into the bent portion .
A plurality of lubricant introduction holes 7 for supplying the lubricant 2 and a pipe chute 8 for applying a lubricant having an inner diameter capable of allowing the work 2 to pass through with sufficient margins. By being supported, it is housed detachably.

Reference numeral 9 denotes a belt conveyor for discharging the work facing the outlet end in front of the pipe chute 8 for supplying the work 2 after applying the lubricant to a press device (not shown).

When the work 2 heated to a predetermined temperature by the heating device 4 is sequentially fed into the pipe chute 8,
While passing through the bent portion immersed in the lubricant 5, the lubricant 5 is applied to the entire individual work 2, and is sequentially sent out to the belt conveyor 9.

[0008]

In the work supply line described above, as the amount of application to the work 2 increases, the liquid level of the lubricant 5 in the storage tank 6 gradually decreases, and the bent portion of the pipe chute 8 Is exposed, the application of the lubricant 5 to the work 2 is not performed.

In order to prevent this, conventionally, the remaining amount of the lubricant 5 is inspected from time to time, and when the liquid level falls below a predetermined level, the lubricant 5 diluted to a certain concentration is replenished relatively frequently. The work of adjusting the concentration and the work of replenishment were very troublesome.

Some works do not require the application of the lubricant 5, and when such works are conveyed using the same work supply line, a straight pipe chute as shown in FIG. I needed to change it to 10. In this case, not only is the replacement operation troublesome, but also if the material and dimensions are different, it is necessary to extract the work remaining in the chute when replacing the pipe chute.

The present invention has been made in order to solve the above-mentioned problems. By making it possible to arbitrarily adjust the liquid level, the frequency of replenishing the lubricant can be greatly reduced, and one liquid can be added. It is an object of the present invention to provide a lubricant applying device with a liquid level adjusting device that can share a pipe chute.

[0012]

In order to achieve the above object, the present invention provides a lubricant storage tank having a substantially U-shaped intermediate portion.

The present invention provides a lubricant application device with a liquid level adjustment device, wherein the lubricant application device can be adjusted.

[0013]

[Action] By simply moving the telescopic rod up and down by operating the raising and lowering means and raising and lowering the tank attached to the lower end of the telescopic rod, the liquid level in the storage tank is arbitrarily adjusted, and the work is carried.
Dip the bent part of the feeding chute into the lubricant

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The same members as those in the above-described conventional example are denoted by the same reference numerals and described.

FIGS. 1 to 3 show the liquid level of the present invention provided in the middle of a supply line of a work for warm forging, similarly to the conventional example.
Indicates the attached leveling system lubricant applicator, lubricant
(Liquid) Side plate 6 on the left (left side in FIG. 2 ) of storage tank 6
An air cylinder 13 serving as an elevating means projects a piston rod 13a downward on a horizontal piece 12a of an inverted L-shaped bracket 12 fixed with a bolt 11 above the center of the b. It is fixed.

At the lower end of the piston rod 13a, the central part of the upper surface of a sealed rectangular cylindrical tank 15 is attached by a bolt 17 via a support plate 16. Tank 15
The left and right sides of the storage tank 6 extend from the lower end position where the lower end thereof is close to the bottom plate 6c of the storage tank 6 to the upper limit position where the lower end thereof is located almost in the middle of the storage tank 6 due to the expansion and contraction movement of the piston rod 13a. You can go up and down along. The air cylinder 13 and the tank 15 constitute a liquid level adjusting device.

Reference numeral 8 denotes a substantially U-shaped intermediate portion similar to the conventional one.
It has a bent part with a bend, and
A work transfer pipe chute provided with a number of lubricant introduction holes 7 , both ends of which are supported by side plates 6 a before and after the storage tank 6.

Thus, when the work 2 to which the lubricant 5 needs to be applied is conveyed, the compressed air is sent to the air cylinder 13 by operating the air valve (not shown), and the piston rod 13a is projected downward. Then, the tank 15 attached to the lower end moves down to the lower limit position, sinks into the lubricant 5 and raises its liquid level.

As a result, as shown in FIG. 1, the bent portion of the pipe chute 8 is immersed in the lubricant 5, and the lubricant 5 is applied to the work 2 passing through the pipe chute 8.

On the other hand, when the workpiece 2 to which the lubricant 5 does not need to be applied is conveyed to the next process through the same pipe chute 8, the air valve is opened to the atmosphere and the air cylinder 1 is opened.
The compressed air in 3 is discharged to retract the piston rod 13a upward. Then, the tank 15 rises to the upper limit position and comes out of the lubricant 5 as shown in FIG.

As a result, the liquid level which has risen so far drops, and the entire pipe chute 8 is exposed from the lubricant 5. Therefore, the lubricant 5 is not applied to the work 2 passing through the pipe chute 8.

In this manner, the lubricant 5 is applied to the work 2 passing through the pipe chute 8 simply by moving the tank 15 up and down by operating the air cylinder 13 and raising and lowering the liquid level of the lubricant 5. It is not necessary to replace the pipe chute each time as before,
One pipe chute 8 can be shared.

In the above embodiment, the air cylinder 13
When the tank 15 is moved down to operate, the case where the tank 15 is lowered to the lower limit position at one time has been described, but the pressure of the compressed air supplied to the air cylinder 13 is adjusted by, for example, an air valve with a pressure adjusting device. The amount of protrusion of the piston rod 13a may be changed as appropriate, and the amount of sink of the tank 15 into the lubricant 5 may be increased according to the remaining amount of the lubricant 5.

By doing so, the liquid level of the lubricant 5 can be maintained at a constant level until the remaining amount of the lubricant 5 reaches a certain level. Even if the applied amount of the agent 5 is increased and the liquid level is lowered, it is not necessary to supply the lubricant 5 each time.

Even when the tank 15 is lowered to the maximum, the lubricant 5 may be replenished when the liquid level does not reach a position at which the bent portion of the pipe chute 8 can be immersed. Extremely low.

In the storage tank 6, a liquid level gauge (not shown) having a variable resistance type detector for emitting a signal based on, for example, a displacement of the float is provided. By controlling the pressure of the compressed air supplied to the tank, the liquid level can be automatically adjusted to a constant level.

The lifting means may be a hydraulic cylinder, a screw feed mechanism driven by a motor or the like instead of the air cylinder 13.

[0028]

[Effect of the Invention] According to the present invention, lubrication of a lubricant application device is achieved.
Since agents may arbitrarily adjust the liquid level in the storage tank, Jun supply frequency of lubricant not only is significantly less, regardless of the presence or absence of the lubricant to the workpiece coating, the pipe chute lubricant coating Exchange becomes unnecessary and sharing can be achieved.
