Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to forming a first rod material by winding a prepreg containing reinforcing fibers around a mandrel, and winding a thermoforming tape around the outer peripheral surface of the first rod material and firing it. The present invention relates to a method for polishing a surface of a rod material, which comprises forming two rod materials and polishing the outer peripheral surface of the second rod material.

[0002]

2. Description of the Related Art Conventionally, for polishing a second rod material, a second rod material, which has been previously peeled from a thermoforming tape, is sandwiched between two opposing grinding rolls, and the thermoforming tape is wound. The centerless surface polishing method of grinding the irregularities formed on the circumferential surface of the rod has been adopted.

[0003]

In the case of such a centerless system, the grinding roll itself must simultaneously grind while maintaining the second rod material in a predetermined posture.
When the rotation of the grinding roll is irregular or there is a difference in rotation speed between the left and right grinding rolls, the second rod material may be blown off from the grinding roll, and the second rod material may drop from between the grinding rolls. There was a difficulty in controlling the rotation. In addition, since the amount of biting of the grinding roll changes due to fluctuations in the rotation speed of the grinding roll, it is difficult to set the grinding amount, and the direction of the grinding roll is orthogonal to the rod axis center with respect to the prepreg located at the outermost periphery. There is also a problem that the reinforcing fiber is easily damaged and the rod strength is lowered because the reinforcing fiber acts to peel off the reinforcing fiber. An object of the first invention is to propose a surface polishing method capable of performing grinding easily and quickly by rationally setting a grinding movement direction of a grinding tool.

[0004]

According to the first aspect of the present invention, the second rod material is installed in a standard posture, and one of the surface grinding tool and the second rod material is relatively moved in the axial direction of the rod axis. The effect is as follows.

[0005]

By setting the second rod material in the reference posture, grinding can be performed in a state where the relative postures of the surface grinding tool and the second rod material do not change even during the grinding process.

[0006]

Therefore, if the grinding amount is properly set, the grinding amount does not change over the entire length of the second rod material, and the grinding amount is appropriate and the reinforcing fiber is not damaged.

An object of the second invention is to provide a surface polishing apparatus which can grind easily and quickly by sharing the functions of the grinding tool and the second rod material.

[0008]

According to a second aspect of the present invention, there is provided a support base for setting the second rod material in a standard posture, and a rod axis direction of the second rod material installed on the support base. It is composed of a surface grinding tool that moves in parallel and polishes the outer peripheral surface of the second rod material, and the operation and effect thereof are as follows.

[0009]

[Operation] The support base is made to have the function of merely installing the second rod material in the standard posture, while the surface grinding tool is mounted on this support base and has the same basic condition as the second rod material that does not change the rod shaft. By providing a function only for moving in the core direction and sharing the functions between the support base and the surface grinding tool,
The rod material can have a strong support form so that the rod axis does not move, and by establishing this reference state, the surface grinding tool will have a structure that only moves parallel to the rod axis. Just enough.

[0010]

Therefore, even if the moving speed of the surface grinding tool changes due to a change in grinding resistance, the grinding amount does not change, and the second rod material is not repelled by the surface grinding tool. It is not necessary to control the movement speed of the surface grinding tool as strictly as in the conventional configuration, and the inconvenient situation that the work efficiency is reduced due to the second rod material falling off the support base and the installation work is redone. There is also an effect that can be avoided.

EXAMPLE An explanation will be given based on a manufacturing process of a rod material. As shown in FIG. 1, (a) A fixed prepreg first layer 1 is placed on a surface plate, and a mandrel 2 is rolled on the upper surface of the prepreg first layer 1 to wind the first layer 1. The first layer 1 is made of resin impregnated with reinforcing fibers such as carbon fibers, and the carbon fibers are aligned in the circumferential direction of the rod. (B) As shown in FIG. 2, the second layer 3 made of prepreg is wound around the peripheral surface of the first layer 1 to form the first rod material. In the case of this second layer 3, the direction of the carbon fibers is set to be parallel to the rod axis direction. (C) As shown in FIG. 2, the second layer 3 may be the outermost layer, but the first layer 1 and the second layer 3 may be stacked as one set and a plurality of sets may be stacked. (D) As shown in FIG. 3, in this embodiment, the second
When the layer 3 is the outermost layer, a thermoforming tape 4 of ester or the like is wound around the outer peripheral surface of the second layer 3 and fired after winding to form the second rod material 5. After that, the second rod material 5 goes through a peeling process of the thermoforming tape 4 and then enters a polishing process. (E) Next, the polishing apparatus A is used to polish the step unevenness formed on the rod circumferential surface by the thermoforming tape 4.

The polishing apparatus A will be described. As shown in FIG. 4, a support base 6 on which the second rod material 5 is placed is provided, and an installation groove 6 for dropping and positioning the second rod material 5 on the support base 6.
Form A. The second rod material 5 has the upper body exposed while being installed in the installation groove 6A. Auxiliary patterns 7 and 7 are wound around the rod tip and the rod butt end of the second rod material 5, and the second rod material 5 is fixed to the auxiliary patterns 7 and 7 by using appropriate clamp mechanisms 8 and 8. However, even in the fixed state, the second
The clamp state is adjusted so that the rod material 5 can be rotated around its rod axis, and the rotary drive mechanism B is connected to the rod tip to switch the grinding surface. On the other hand, a surface grinding tool 9 that moves in contact with the upper surface of the support body 6 is provided, and a concave portion 9A is formed on the lower surface of the surface grinding tool 9 to cover the exposed upper body of the second rod material 5 and perform grinding operation on the upper body. Recess 9 to add
The inner diameter of A is set as the grinding surface and the inner diameter is set. Downward projecting ridges 9B and 9B are provided on both sides of the recess 9A, and the ridges 9B and 9B are fitted into the support base 6 to form guide grooves 6A for guiding the surface grinding tool 9 in the rod axis direction. Formed,
Further, a drive moving means 10 such as a hydraulic cylinder is connected to the surface grinding tool 9, and the drive moving means 10 and the guide groove 6A cooperate with each other to reciprocate the surface grinding tool 9 along the rod axial direction. . The above structure is called a polishing apparatus A. (F) When the polishing step is completed, the rod tip portion and the rod tail portion are cut off to form a rod material having a predetermined length. As described above, the configuration in which the surface grinding tool 9 is moved in the rod axis direction with respect to the prepreg in which the carbon fibers are aligned in the rod axis direction reduces damage to the carbon fibers.

[Other Embodiments] The following may be used as the first rod material. That is, as the prepreg, a cross-shaped prepreg in which reinforcing fibers are arranged in the rod axial direction and the rod circumferential direction may be used. The reinforcing fibers of the prepreg located on the outermost periphery may be aligned in the rod circumferential direction.
It is the second rod material 5 that is moved during grinding, or
Either the grinding tool 9 or the second rod material 5 may be moved. Another embodiment of the polishing apparatus A will be described. Figure 5
And, as shown in FIG. 6, a longitudinally rotatable endless belt 11 is wound above the support base 6 to rotate along the rod axial direction of the second rod material 5 placed on the support base 6. At the same time, the polishing layer 11a is attached to the outer surface of the endless belt 11 to form the sander belt type surface grinding tool 9. Inside the endless belt 11, a rubber presser body 12 that moves along the rod axial direction of the second rod material 5 is provided, and as shown in FIG.
The lower surface of the pressing body 12 is recessed so as to follow the outer peripheral surface of the second rod material 5 in the state of pressing. In the figure, 13 is a spiral body that indirectly acts on the presser body 12 to drive and move it,
Reference numeral 14 is a drive means for rotating the spiral body 13. Again 1
Reference numeral 5 denotes an urging spring for urging the pressing body 12. With the above configuration, the belt 11 is rotated in one direction, and the pressing body 12 is moved in the forward and reverse directions in the arrow direction to perform surface polishing.
