ある。 The plastic material 1 used in the present invention is a metal material, mainly iron. Its shape is generally linear or rod-like, but it may also be block-like,
Further, it may be either hollow or solid, and its cross-sectional shape may be round, square, triangular, or other.
Here, the hollow bar 1a will be explained as an example. A long hollow bar 1a is drawn or rolled using a die to form grooves 2 on the entire surface along the longitudinal direction, as shown in FIG. 2b. Although its cross-sectional shape is as shown in FIG. 2a, it is of course not limited to this, and the number of grooves 2 can be increased or decreased as required. After grooving in this way,
Cut to specified dimensions. Next, a forging tool is inserted into both ends of the hollow bar 1a to bulge out the groove 2 of the end 3 and return the end shape to its original shape as shown in FIG. 3b. As a result, the grooves 2 at the end portions 3 disappear, and the grooves 2 remain only in the center portion of the surface of the hollow bar 1a. If a product with grooves 2 formed only in the center of the surface is required, use this state as a finished product. Furthermore, if it is necessary for the groove 2 to open on the inner circumferential surface 4, lathe machining is performed along the inner circumferential surface 4.
Cut off the bottom of the groove by drilling or reaming,
The groove 2 is opened in the inner circumferential surface 4. In this case, it is necessary that the groove bottom surface is recessed inward from the inner circumferential surface 4. When a solid bar 1b is used, after the groove is formed, a forging tool is driven into both ends to bulge out both ends of the solid bar 1b, as shown in FIG. As shown in the figure, if the bulging allowance is larger than the diameter of the solid bar 1b, cutting will be performed on the bulging allowance shown by diagonal lines. Furthermore, by boring the center of the solid bar 1b, the hollow bar 1a described above can be formed.

固着する。 Next, an example of the use of the method of the present invention will be described with reference to FIGS. 6 and 7. FIG. 6 is a perspective view of the board anchor 11, in which one end of the main body portion 12 is bulged into a hexagonal nut shape by swaging, for example, to form a screw head 5, and the other end has a female thread on the inner periphery. 6 is screwed. Four grooves 2 are formed in the center of the body by the method described above, and are open toward the inner circumference.
A through hole 7 for stealing meat is bored in the center of the groove 2. A through hole 8 is then bored in the material to be fastened 13, the main body portion 12 is inserted into the through hole 8, and the bolt 10 is screwed into the female thread 6 and tightened. Then, the part of the thin through hole 7 is buckled and bent outward, and the bent part 9 and the head 5 strongly fix the fastened member 13 as shown by the imaginary line.

適であるという利点がある。 As described above, the present invention involves forming a groove from one end of the plastic material to the other end by plastic working the surface of the plastic material, and then bulging the end of the plastic material by plastic working to form a groove. Since the grooves on the surface disappear, it is extremely easy to form a shape with grooves remaining only in the center of the surface of the plastic material, making it ideal for products that are used in large quantities and are inexpensive, such as board anchors. There is an advantage to having one.
