[Technical field to which the device belongs]

 The present invention relates to a type of double-sided roller type lubricating oil application device, and more particularly, to a device designed for applying lubricating oil to the surface of a press material and capable of smoothly supplying oil and evenly applying an oil material.

[0002]

[Prior art]

 When pressing metal, there is a problem that high heat is likely to be generated due to strong pressure contact between the die and the material, which shortens the service life of the die. Lubricant is applied to the surface to increase the lubricity of the contact between the mold and the material and to reduce the high temperature effect, thereby extending the service life of the mold.

In order to apply the lubricating oil to the surface of the press material, one lubricating oil applying mechanism 11 is provided on the feed side of the press 10, and the lubricating oil applying mechanism 11 applies the lubricating oil to the surface of the pressing material. I do. In its design, one frame-shaped mounting base 12 is mainly used, a plurality of oil supply members 14 are provided on the bottom edge of the upper oil tank 13 on the upper side thereof, and the amount of oil supplied by the oil supply member 14 is higher than that of the upper oil tank 13. Controlled by the corresponding fine adjustment valve member 15 installed in the above, the lower side of the above-mentioned mounting base 12 is a semi-open type lower oil tank 16, on which two sets of rollers covered with felt are installed. The upper roller 17 is slightly brought into contact with the oil supply member 14, and the lower roller 18 is immersed in the lower oil tank 16 to allow the press material to pass between these two rollers. Has achieved. Lubricating oil is supplied to the upper oil tank 13 and the lower oil tank 16 by means of an oil jar 20 hung on one side of the machine body of the press 10. Suspended on one hanger 21 manufactured by folding in the bay, and equipped with one simple control valve 22 to open and close the oil passage, and with the above, provide a lubricating oil application device for press material before pressing, It corresponds to the implementation of the plus processing work.

The construction of the device described above had the following drawbacks in practical use: Since the oil jar is hung on one side of the press body and is not fixed to the oil jar, the vibration of the oil jar causes the oil jar to oscillate during the progress of press working, which causes smooth lubrication. Was affected. 2. The oil jar is designed as a single solid and can only accommodate one kind of lubricating oil.However, when pressing different materials, it is sometimes necessary to apply a special cutting oil. The lubricating oil in the vase could not be applied, and it was necessary to either take out the internal lubricating oil and replace it with the applicable oil, or to replace the entire oil vase, which was inconvenient and troublesome. 3. Although a control valve is installed below the oil jar to control refueling, since it is a general simple mechanical valve member, its state easily changes due to vibration during press working. It is inconvenient because it has to be closed artificially after it has stopped working smoothly and the machining operation has completely stopped.In addition, if the operator forgets to close the valve, the oil in the oil tank will overflow and Formed waste. 4. Oil is supplied to the upper roller by the oil supply member of the upper oil tank, and the amount of oil supply is controlled by the fine adjustment valve member.However, the vibration generated during press working is transmitted to the fine adjustment valve member, and Vibration was likely to occur, loosening and dropout were likely to occur, which affected the amount of oil supply and caused the phenomenon of uneven oil application. 5. The surface of the roller is covered with felt that has excellent oiling properties. When the roller is new, the two rollers contact the press material evenly, but after a certain period of use, the roller absorbs oil and the felt fibers become dense. As a result, the volume decreased, which caused the gap between the two rollers to widen, resulting in poor contact with the press material, which affected the uniformity of the oil coating. 6. There are differences in the specifications of press materials depending on the product, so it is necessary to control whether or not lubrication is performed by the lubrication member using the fine adjustment valve material. Then, when oil is applied to a material of a certain standard, that part of the felt becomes dense due to oil absorption and contact with the press material due to the high usage rate of the corresponding area of the roller, and the volume is reduced. Therefore, the phenomenon of roller surface irregularity occurred, and the uniformity was affected when the oil was applied to different press materials at a later date. 7. Since the lower roller is immersed in the lower oil tank, the lower roller absorbs a relatively large amount of oil, which not only accelerates the densification speed of the felt oil, but also increases the amount of oil applied to the lower surface of the press material. Became a waste of oil. 8. The felt that covers the roller needs to be replaced because it becomes saturated with oil after being used for a certain period of time, which is troublesome and expensive. 9. Since the supply of lubricating oil is done in a single direction, in the lower oil tank, the amount of oil stored in the press material decreases due to the oil applied to the press material, and the amount of oil applied to the lower surface of the press material must be replenished as needed. Gradually became thin, and the phenomenon of non-uniformity of oiling occurred. As can be seen from the above points, the structure of the above-mentioned device is not perfect, so that it may cause some defects in actual use and affect the press working work, and it is still the best industrial use. It had no value and needed improvement.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to prevent a fine adjustment valve member from slackening and deviating due to vibration by utilizing a pressing position limitation to the fine adjustment valve member in which a set of spring pieces are chained in an upper oil tank. Maintains the set amount of lubrication of the lubrication member to prevent uneven lubrication phenomenon, while at the same time, one fixed base for supporting the oil vase is installed on one side of the machine body, and the vibration of the press causes the vibration of the vase to rock. The purpose of this is to prevent the occurrence of noise and to supply oil smoothly, and to improve the influence of vibrations that occur in press work on the fine adjustment valve member and oil supply to the oil supply.

The next subject of the present invention is to use a roller made of a synthetic rubber material instead of a conventional roller coated with a felt, and use the characteristic that the synthetic rubber material does not deform even if it absorbs oil. Under the condition that the oil effect is not affected, the uniformity of the oil coating is enhanced, and the roller has a three-layer design, and the press material is passed between the upper and middle layers of the roller, and directly below. The lower roller, which is immersed in an oil tank, should not be brought into contact with the lower roller, and the lower roller should be contact-coated to apply oil to the lower surface of the material with the intermediate roller. It is to prevent the uniform phenomenon.

Still another object of the present invention is to provide one float-type liquid level switch in the lower oil tank, and combine this with a solenoid valve provided in an oil jar to maintain a fixed amount of oil in the lower oil tank. This is an issue.

It has an oil pot 31 which is hung on one side and supplies oil to the lubricating oil applying mechanism 40. The oil jar 31 is a two-tank oil jar, and can accommodate two different kinds of oil, and is received in a fixed base 32 chained to one side of the machine body 30, whereby press working is performed. It is possible to prevent the vibration during work from oscillating the oil jar and to provide lubrication smoothly. The oil jar 31 has its inner tank connected to one oil output pipe 33 and 34, respectively, and is connected to one two-way solenoid valve 35 for controlling opening and closing, and then connected to a lubricating oil application mechanism 40 by an oil pipe 36. Has been done. The solenoid valve 35 is used for conversion when different oils in the two inner tanks of the oil jar 31 are selected, thereby eliminating the trouble and inconvenience of exchanging the oil. Since the press mechanism of the press is connected to the press mechanism, when the press mechanism stops the machining operation, the solenoid valve 35 is triggered to shut off the oil passage and stop the oil supply. As a result, an automatic opening / closing function of the oil supply is provided, and manual control is not required, and at the same time, there is no disadvantage that the mechanical control valve is slack and easily deviates due to vibration. As a result, the lubrication oil application mechanism 40 can be supplied with oil more smoothly.

Next, as shown in FIGS. 4, 5 and 6, in the lubricating oil application mechanism 40 of the present invention, a set of tightening spring pieces 50 is connected to one side of the upper oil tank 42 of the mounting base 41. The pair of tightening spring pieces 50 are substantially L-shaped and correspond to the pressing spring pieces 51 respectively formed on the one fine adjustment valve member 43 of the upper oil tank 42. The form of the piece 51 is provided with a characteristic of performing contact positioning with respect to the fine adjustment valve member 43, and on the contact surface of the pressing spring piece 51 and the fine adjustment valve member 43, one protruding rib 52 is further formed by pressing. Is provided, so that the fine adjustment valve member 43 is closely fitted with the rib pattern formed on the swivel knob portion, the state of the fine adjustment valve member 43 is maintained, and the press material of the mold is processed. Fine adjustment due to conduction of vibration during installation to the mounting base 41 The slack of the valve member 42 is prevented, so that the amount of oil supplied by the oil supply member 44 is secured, and the amount of oil supplied to the upper roller 46 is maintained at an appropriate amount. That is, the problem of non-uniform oil coating formed on the material due to the excessive or excessive amount of oil of the upper roller 46 is solved.

Further, as shown in FIGS. 4 and 7, another design point of the present invention is that a synthetic rubber roller is adopted in place of a conventional felt-coated roller, and the roller is upper, middle, or lower. , The lower three-layer design, in which the upper layer roller 46 substantially contacts the oil supply member 44 of the upper oil tank 42 and the lower layer roller 48 is placed in the lower oil tank 45 and The roller 47 and the lower layer roller 48 are in contact with each other, and the press material 60 is supposed to pass between the upper and middle layer rollers 46 and 47. With this design, the upper layer roller 46 is supplied with oil directly by the oil supply member 44 of the upper oil tank 42, and the amount of oil supply is maintained constant by the action of the set of tightening spring pieces 50. Refueling is performed by applying by contacting the lower layer roller 48 attached from the lower oil tank 45, so that the oil amount in the middle layer 47 does not become excessive and is maintained in a uniform state. The effect that the oil coating on the upper and lower surfaces of the press material 60 of the rollers 46, 47 in the middle layer is uniform is achieved. In order to prevent waste of oil, the amount of oil in the lower oil tank 45 is provided with a single float-type liquid level switch 49 inside the lower oil tank 45, which is combined with a solenoid valve (see FIG. 3) of an oil bottle. The oil amount in the lower oil tank 45 is adjusted by the adjustment, and a function is provided to automatically replenish and replenish the oil amount in the lower oil tank 45 when it is insufficient.
