Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a material oiling device that applies a processing oil to the entire surface of a tape-shaped material when pressing a fin of a cooler.

[0002]

[Prior Art]

 In the conventional fin processing press, the material coating oil is partly immersed in the processing oil in the oil tank, and a rotating roll is contacted with a rotating roll that has hard urethane rubber baked on its surface. The material was sandwiched between and the processing oil was applied to both sides of the material.

[0003]

[Problems to be solved by the device]

 Since the fins of the cooler are made of an aluminum material, it is easy to make a rehabilitation edge on the die when press working, and if the rehabilitation edge is formed, the sharpness will deteriorate. Processing oil is applied to the material fed from the pinch rolls in order to prevent the occurrence of rehabilitative cutting edges and prolong the life of the mold.However, if too much processing oil is used, the material will adhere to the mold and the specified length will be exceeded. It becomes impossible to feed the material, and if it is too small, the life of the mold will be shortened.

When the processing oil is applied by the conventional transfer roll method, the desired oil film thickness cannot be obtained due to the gap between the upper and lower transfer rolls, the viscosity of the oil, the processing accuracy of the roll, etc. I can't do it either. If it is used for a longer period of time, the hard urethane rubber baked on the surface of the transfer roll will be worn and the oil film will become thin.

[0005]

[Means for Solving the Problems]

 The present invention solves the above problems and provides a material oiling device capable of uniformly applying a desired oil film, which is a fluid permeation system in which cast iron and a ceramic porous body are combined in a part of the main body. A roll-shaped oiling member made of cast cast iron is provided with an oil supply hole, and the fluid-permeable cast iron of a pair of oiling members with oil supply pipes connected to the oil supply hole are supported by a holder facing each other at a predetermined interval. It is characterized by being present.

[0006]

[Function and effect of the device]

 When the processing oil is supplied from the oil supply pipe to the oil supply hole of the oil coating member, the processing oil is ejected in the form of fine mist from a large number of three-dimensional stitch-shaped holes of the fluid permeable cast iron. The material fed from the pinch roll is covered with mist-like working oil ejected from the upper and lower oiling members, so that the working oil is evenly applied to the entire surface of the material.

Since the flow rate of the processing oil that permeates the fluid-permeable cast iron is proportional to approximately the square of the supply pressure, the thickness of the oil film applied to the material can be adjusted by adjusting the pressure of the processing oil that is supplied. It can be of any desired thickness.

Therefore, the thickness of the oil film applied to the material can be easily controlled, and the oil can be applied under the best conditions for press working, so that the quality of the pressed product can be improved and the life of the die can be greatly improved. can do.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1 and FIG. 3, the oil coating member 1 is a part of the body 2 of cast iron in a roll shape, and is formed into a circular arc shape of 30 ° to 50 ° and has a fluid permeation which is a composite of cast iron and a porous ceramic body. The cast iron 3 is cast and integrated.

The fluid permeable cast iron 3 which is a composite of cast iron and a ceramic porous body has a characteristic of fluid permeability in which three-dimensional mesh-like continuous triangular holes are regularly arranged, and the fin of a cooler is used. For refueling, the fluid permeable cast iron having a hole size (which means the size of one side of a triangular shape) of 0.4 to 0.7 mm and a number of holes of 9 to 13 / cm ² is suitable.

An oil supply hole 4 communicating with the fluid permeable cast iron 3 is formed from one end of the oil application member 1, and the oil supply hole 4 is connected to an oil supply pipe 6 via a joint 5 screwed to the oil supply member 1. ..

Shafts at both ends of the pair of oil coating members 1 are fixed to the holder 7 by caps 9 fastened to the holder 7 by bolts 8, and the permeable cast iron 3 of the oil coating members face each other at a predetermined interval A. There is. If this interval A is the minimum interval for finishing the outer shape of the oil coating member 1 with high precision by machining and allowing the material W to pass through, the atomized processing oil ejected from the fluid permeable cast iron 3 is scattered around the surroundings. It can be applied to the material W with a minimum amount of application.

In FIG. 1, 11 is a regulator, 12 is a pressure gauge, 13 is a check valve, and 14 is a pump. The pressure of the working oil supplied to the oil coating member 1 can be adjusted by the regulator 11. Is becoming

The material W wound around the coil material 21 is sandwiched between a pair of pinch rolls 23 rotated by a motor 22 as is known, and is fed at a constant speed. The material W fed at a constant speed is slackened in a U shape between the idle rollers 24.25 and temporarily stored, and the slack material W is intermittently fed to the press machine by a predetermined length by a feeding device (not shown). As shown in FIG. 4, the material oiling device 20 is press-worked, and is installed between the pinch roll 23 and the idle roller 24 to apply oil to the material W fed at a constant speed from the pinch roll 23. ..
