Description

Oil coating apparatus for press material

The present invention relates to a press material oil application device that applies oil to the surface of a press material, and in detail, by setting an oil application section so that oil is sprayed as much as the width of the press material, oil loss is prevented, and oil is removed. It was applied in duplicate (twice) to achieve a uniform oil application.

In general, a press device is a device that produces a product (part) by pressing a material and is widely used for mass production of products.

The material introduced into the press device has a problem in that a part of the surface of the press material is damaged or cracks and noise are generated due to frictional force pressed by a high pressure during the molding process. Therefore, oil such as drawing oil is applied to the surface of the press material before the press material is put into the press device.

Conventionally, since the operator sprayed oil directly on the surface of the press material and applied it, not only the oil was blown (spattered) around the work site very dirty, but also harmful substances contained in the oil could easily reach the worker's respiratory tract or skin. There is a problem of causing disease by being inhaled, and there is a problem such as a high cost loss because the quality is deteriorated and productivity is deteriorated because uniform oil application is not made depending on the worker, and the oil blown to the workplace is wasted as it is.

In order to solve such a problem, a device for applying oil to the press material surface by configuring an application roller that can contain oil on the surface of the rotating roller has been proposed. However, by forming an oil hole inside the shaft bar of the application roller, It is a method in which the oil is applied to the surface of the press material while the oil is ejected out of the application roller, so that even spraying does not occur, so the application is not uniform, and it is difficult to control the amount of injection. Since it is a structure that sprays oil in a wide width, there are various problems such as excessive oil waste.

The state of use of the oil application device 1 of the present invention is as follows.

First, the material adsorption means of the material carrying unit descends to the material loading device by the controller (not shown), adsorbs the press material 10 loaded on the top, and then moves upward and puts it onto the inlet conveyor belt 11 The press material 10 is returned to transport the next press material 10, and the press material 10 seated on the inlet conveyor belt 11 passes between the upper and lower application rollers 5 and 7 in the front, and the primary oil 14 The press material 10a, which is applied and leaves the front upper and lower application rollers 5 and 7 while being applied with the primary oil, enters between the upper and lower application rollers 6 and 8 at the rear, and the secondary oil 14 is applied. The press material (10a) exiting the rear upper and lower application rollers (6) (7) while the oil of an appropriate thickness is evenly applied passes between the guide members (39) (40) by the outlet side conveyor belt (12) Upon arrival, when the arrival of the press material 10a is detected by the proximity sensor 41 located at the outlet, the material adsorption means of the material discharging unit descends by the controller to adsorb the press material 10a and then move it into the mold. Then, the press material 10a returned to the mold and brought into the mold is punch-molded by the mold. At this time, the press material 10a to be punch-molded is coated with oil 14 of a uniform thickness on the surface, so that a part of the surface of the press material 10a to be molded is not damaged or cracked, so that good molding is achieved, and the mold is not damaged. It is prevented and the service life is prolonged, and molding noise generated during press work is also drastically reduced.

At the end of the outlet side conveyor belt 12, separation or fall of the press material 10a is prevented by a base 2b protruding upward, and a material adsorption means installed in the material carrying unit is provided to the press material 10a. When adsorbed and transferred to the press mold, the proximity sensor 41 detects the discharge of the press material 10a, and the controller lowers the material adsorption means of the material carrying unit to the material loading device and is loaded on the top of the press material 10. The continuous oil application is achieved by repetition of the process of adsorbing and then moving upwards and putting it onto the inlet conveyor belt 11 and then returning to transport the next press material 10.

In the present invention, since the oil 14 is automatically applied to the surface of the press material 10, the operator uses the oil 14 on the surface of the press material 10 in order to apply the oil 14 to the press material 10 as in the prior art. ), so it is not necessary to spray and apply the oil (14), so that the work area is not very dirty or harms the human body.

In the present invention, since the oil 14 is applied by the application rollers 5, 6, 7 and 8, the oil 14 is not scattered to the periphery, and the oil 14 falling after application is collected in the oil collecting tank 16. Since it can be filtered and reused after being filtered, the waste of oil 14 is prevented and cost is reduced.

In the oil spraying means 14 of the present invention, the oil 14 is sprayed by the proximity sensors 33 and 34 into the oil spraying section L having a length equal to or slightly longer than the width w of the press material 10a. As it is applied, the consumption of the oil 14 can be reduced, thereby reducing the loss and cost of the oil 14.

In the present invention, in consideration of the width (w) of the press material (10), the oil injection section (L) is set by moving the position of the proximity sensors (33) (34), and the oil injection that reciprocates along the cam screw (17) Since the means 15 sprays and applies the oil 14 only in the oil spray section L, waste of the oil 14 is prevented.

In addition, when the width (w) of the press material 10 to be applied with oil is changed, the proximity sensors 33 and 34 installed on the support bar 29 are moved so that the oil 14 is removed in the changed width (w) section of the press material. Since the oil spray section (L) can be set so that it can be applied, the oil 14 is sprayed and applied only in the width w section of the press material 10, thereby preventing the waste of the oil 14.

The present invention described above is not limited to the present embodiment and the accompanying drawings, and various substitutions, modifications and changes can be made within the scope of the technical spirit of the present invention, which in the technical field to which the present invention pertains.
