Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a groove on the outer peripheral surface of an end portion of U-shaped steel or the like, and more particularly to a method suitable for a thin material. It is provided. 2. Description of the Related Art A conventional invention proposed by the applicant of the present invention for forming a groove on the outer peripheral surface of an end portion of a square column material, a round pipe material or the like (see Japanese Patent Publication No. 2-48370). It has been known. According to the present invention, the copying roller is brought into contact with the peripheral surface of the work, and the required groove processing is performed on the peripheral surface end portion by a cutter concentric with the copying roller. It is possible to perform groove forming of U-shaped steel, for example, using the above method.
However, in this type of steel material, since the side surface of the work is open, there is a problem that large vibration occurs when cutting the side end portion, resulting in poor accuracy and chipping of the cutting edge. When the steel material is thin, the problem is more serious and becomes uncut. Further, since the thin-walled steel material itself has a low structural strength, a large vibration is generated even at portions other than the side edges. The present invention has been made in view of the above-mentioned problems of the prior art. Even a thin steel material having an open side surface can be smoothly cut without vibrating. It is intended to provide a pre-processing method. A groove processing method for achieving the above object is as follows. That is to say, the gist of the point is that the abutting member is inserted from the open side surface of the work to hold the inner peripheral surface of the work, and the abutting member performs the cutting process under the pressing force of the copying roller. is there. Embodiments of the groove processing method according to the present invention will be described below. FIG. 1 is a front view of a groove processing apparatus to which this method is applied. FIG. 2 is a side view of the same. 1 is a table A is a U-shaped steel on the table 1 (hereinafter, simply a work W).
It is a clamping means that clamps
It is composed of a pair of vice pieces 2a, 2b on both sides. The vise pieces 2a, 2b are opened and closed by a well-known driving means. The above-mentioned vise pieces 2a, 2b are provided with pressing surfaces corresponding to the side plates a, b of the work W. Reference numeral 3 is a downward hydraulic cylinder arranged on the upper part of the table 1, and a contact member B is attached to the end of the piston rod 4. The contact member B is inserted into the inside from the open side surfaces (upper side) of the side plates a and b, and the left and right contact surfaces Ba and Bb contact the side plates a and b. Further, the lower contact surface Bc contacts the inner surface of the bottom plate c of the work W. The abutting member B pushes the work W when the piston rod 4 extends and retracts from the work W when the piston rod 4 contracts. 5, 5
Is a cover plate attached to both upper parts of the contact member B, and abuts on the upper ends of the side plates a and b when the work W is pressed by the contact member B. Note that, as shown in FIG. 2, the above-mentioned contact member B is arranged so as to correspond to the vicinity of the tip of the work W. Reference numeral 6 denotes a copying roller 7 which rolls in contact with the outer peripheral surface of the work W. A rotating shaft 8 is arranged concentrically with the center of the copying roller 6. An rotating shaft 8 is attached to the rotating shaft 7 close to the copying roller 6. The conical groove processing cutter 9 is a facing cutter provided so as to be connected to the groove processing cutter 8.
The operation of the copying roller 6 is controlled by a driving means (not shown) so as to move in the direction of a point P in the drawing and move on the peripheral surface of the work W. The structure of the groove processing apparatus according to the embodiment is as described above. Therefore, if the work W is supplied to a fixed position on the table 1 and the work W is clamped by the clamp means A and then the contact member B is operated to the pressing position, the work W is pressed from inside and outside to be firmly held. You can
In this state, as shown in FIG. 1, the copying roller 6 is brought into contact with the peripheral surface of the front end portion of the work W, and the groove cutting cutter 8 and the facing cutter 9 are cut to perform cutting. When the cutter is cut into the open side edge of the work W, the work W is pressed against the contact member B by the copying roller 6. Therefore, the vibration during cutting is suppressed,
Processing can be performed smoothly. Further, even when the copying roller 6 rolls, the cutting position is pressed against the contact member B with it, so that the cutting process is always smooth. The groove-forming cutter 8 forms a rectangular groove at the end of the peripheral surface of the work W as shown in FIG. 3, and the facing cutter 9 finishes the end of the work W at a right angle. In the above embodiment, the case where the work W is thin has been described. However, when the work W is thick and has its own structural strength, the work W is applied only to the open side surface end. It is enough to act the members. FIG. 4 illustrates this case. In the figure, 10 is a pair of vise pieces 2.
The mounting bases 11 provided on the upper portions of a and 2b are hydraulic cylinders that are provided downward on the upper end of the mounting base 10.
Reference numeral 2 is a wedge-shaped contact member attached to the piston rod end of the hydraulic cylinder 11. The above-mentioned pad member 12
Comes into contact with the side plates a and b of the work W during the extension operation of the piston rod, and presses this portion toward the vise pieces 2a and 2b. In the above-mentioned embodiment, the abutting member B is provided in conformity with the internal shape of each work W, but by constructing it as shown in FIG. Can respond. That is, reference numeral 15 is a lift plate 16 operated by the hydraulic cylinder 3, 16 is a hydraulic cylinder 17 a provided laterally on the lift plate 15, and 17 a is a hydraulic cylinder 1.
One contact member provided on the piston rods 6 and 16 1
7b is the other contact member provided on the cylinder cylinder side. 17c is the lower contact member at the lower end of the lift plate 15. As described above, in the groove processing method according to the present invention, the cutting is performed while the inside of the work is firmly held by the contact member. Therefore, vibration is not generated during the cutting process, and the excellent effect that the high-precision processing can be smoothly performed without causing the cutting edge of the cutting edge is exhibited.
