JPS5882672A - Cross hatch patterning method onto tubular surface - Google Patents

Abstract

PURPOSE:To provide a cross pattern easily, stably with high accuracy, onto the surface of a rolling, roll by pressure contacting the grindstone particle adhered to a working member against the outercircumferential face of a tubular member then providing the rotary and reciprocal motion between said tubular member and the working portion. CONSTITUTION:A spindle 4 is inserted through a spring 5 into a holder. Said holder 6 is caught by a chuck 8 moving in the acial direction of a rolling roll 1, where proper size of grindstone 7 is adhered at the tip of the spindle 4. While rotating said roll 1 the chuck 8 is reciprocated to the left and right along the axis of the roller 1 and pressed against the outercircumferential face of the roller 1 thereby a cross hatch pattern 2 is etched onto the surface of the roller 1 by the grindstone particle 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for adding a Kuromeno-Tsuchi pattern to a cylindrical OHM. This relates to a method of adding this Kuromeno-Tsuchi pattern to am of rolling--2.

For cold-rolled steel plates whose surfaces are used as sliding surfaces in the presence of lubricating oil, providing a Surf Eight Gero eye ring, or IIIWK uneven pattern, on this surface reduces friction loss. It is known to be extremely effective against scuffing or seizing. For example, the published patent publication 1987-
In the case of a belt O for a continuously variable transmission using endless thin rolled steel plates stacked in multiple layers as described in No. It is shown in Japanese Patent Laid-Open No. 103133/1983 that the provision of a transmission improves the efficiency of this transmission.

As for the method of installing the Surf 7 sprocket ring on such a steel plate, in the case of the endless metal band, a crosshatch pattern can be added by honing the inner diameter, but in the case of a large diameter metal band or even more endless. The above-mentioned honing is not possible on a steel plate that has not been honed, and an effective method is to add the crosshatch pattern to the surface of the rolling roller and transfer the crosshatch pattern to the surface of the steel plate by rolling the steel plate with this rolling row 2. It is. However, as a method of adding the crosshatch pattern to the surface of the rolling row 2.

Possible causes include photo-etching and manual scratching due to peno-machining, but in the case of the former, adding a fine four-slash pattern to the surface of a special ultra-rich roller requires special and highly advanced techniques. (In the above practical example, the groove depth of the pattern is 1μ and the pitch is 2 to 3μ).Also, in the case of ridges, it is very easy to add a fine pattern by selecting the appropriate grain size of the IPA. It is possible to do this, but since it is done by one person, it is extremely difficult to add the crosshatch angle stably and while maintaining the necessary precision of the rolling rollers.

The present invention was devised in view of the problems of the prior art of adding a crosshatch pattern to the surface of such a rolling roller.
The objective is to provide a technique for stably and highly accurately adding a four-slash pattern to the surface of a rolling roller without impairing the precision of the rolling roller itself.

In order to achieve the above object, the present invention has a structure in which: 1 abrasive grains attached to a workpiece are pressed against the outer periphery of a cylindrical body, and the relative distance between the cylindrical body and the workpiece is A method for adding a crosshatch pattern to the surface of a cylindrical body, which is characterized by performing rotational movement and reciprocating movement in the axial direction of the cylindrical body.
It is from Naruan.

Embodiments of the present invention will be described based on the drawings. FIG. 1 shows a rolling roll to which the method of the present invention has been applied, and the surface of this rolling roll 10 has a floss hatch pattern 2 according to the method of the present invention.
is added. Figure 2 shows the rolling roll 1 shown in Figure 1.
It is an endless belt with a crosshatch pattern.

A crosshatch pattern 2 is formed on the inner peripheral surface of this endless belt 3.
' has been transcribed.

As described above, the present invention relates to a method of adding a crosshatch pattern 2 to the surface of a rolling roll 1 as shown in FIG. It is something. In the figure, a spindle 4 is inserted into a holder 6 via a spring 5, and the holder 6 is held by a chuck 8 that moves in the axial direction of the rolling roll 1 (perpendicular to the plane of the figure). ing. Abrasive grains 7 of a suitable grain size are attached to the tip of the spindle 4 by an appropriate method, and it goes without saying that the grain size is determined by the depth, size, etc. of the groove to be added to the rolling roller 1. It is. In this way.

A cutting tool for processing the rolling mill 1 is constructed.

On the other hand, the rolling roll la processed by the processing cutter
It is held by a rotating chuck (not shown) and can be rotated around its axis (in the direction of the arrow in FIG. 3).

To add a p-shatte pattern to the surface of a rolling roll l using a processing tool configured as described above.

As shown in FIG. 4, while rotating the rolling roll 21 and reciprocating the chuck 8 holding the spindle holder 6 from side to side along the axial direction of the rolling roll 1 as shown by the arrow in the figure, The chuck 8 is moved toward the rolling roll ti until the abrasive grains 7 are pressed against the circumferential surface of the rolling roller 1 with a load of 6, and the chuck 8 is rolled by the abrasive grains 7 attached to the tip of the spindle 4. A crosshatch pattern 2 is engraved on the surface of the roll 10. At this time, rolling roller 1
0 rotational speed W and the left and right reciprocating speed F1 of the spindle 4. By appropriately changing v, the crosshatch angle of the crosshatch pattern can be changed freely. In the above embodiment, the rotational movement of the rolling roll and the left and right reciprocating movement of the processing cutter in the axial direction of the rolling roll were combined, but instead of such movement, the rotational movement of the processing cutter around the circumference of the rolling roll was combined. Of course, it is also possible to combine the reciprocating movement of the rolling rolls in the axial direction.

Since the present invention is as described above, a cross pattern can be easily and stably added to the surface of the rolling roller with high precision, and the high precision of the rolling roller 2 itself is not impaired in any way. This provides a method for adding a crosshatch pattern to a cylindrical body that is far superior to conventional techniques. Furthermore, the surface of the rolling roller has to be re-polished many times during use, but it is clear that this becomes extremely easy when used in conjunction with an outside diameter polishing machine.

Furthermore, the invention is not limited to the rolling roller of the present invention, but can be widely applied to all techniques for adding a crosshatch pattern to the outer surface of a cylindrical surface.
