The feed of the workpiece 1 is stopped when the workpiece 1 is opposed to the workpiece 1, and then the push tool 12 is moved to the right as shown in FIG. Bend it by a certain angle. After this, the first
As shown in Fig. d, the pusher 12 is moved back to its original position, and the feed roller 3 is rotated by a predetermined angle to feed the workpiece 1 to a point a predetermined width away from the already bent point A. is opposed to the outlet side end 11 and feeding is stopped. Then, by moving the pusher 12 to the right again, the workpiece 1 is pressed against the outlet side end 11 and bent by a certain angle as shown in FIG. 1e. By repeating the above operations, the workpiece 1 is bent at a plurality of locations at predetermined intervals. And, there are 42 bends.
If the interval between the two is relatively narrow, the entire part is bent into a curved shape, and if the interval is wide or narrow, several parts separated by the interval are individually bent into a curved shape.

て直角に復元するからである。The bending angles of the - times of the mouth are the same. Furthermore, if the width of the intermittent feed of the workpiece l by the feed roller 13 is kept constant, the mutual intervals between the respective bending points 41 will be the same. From this, when bending an arc-shaped curved part, the above-mentioned intermittent In addition to determining the feed width, the push tool 12
If the number of bends is calculated from the bending angle of the workpiece 1 that is bent by one pressing and the radius of curvature of the curved part to be formed by bending, the accurate curved shape can be calculated using both of these factors as factors. It becomes possible to perform bending processing. Note that the spring bank of the workpiece 1 must be taken into account when determining the bending angle of the workpiece 1 that is bent by one pressing of the push tool 12. Furthermore, when bending the workpiece 1 at a right angle, it is necessary to increase the movement width H of the pusher 12. It is helpful that the pusher 12 is configured to move along an arcuate path A-A, with a smaller, sharply tapered shape. That is, the workpiece 1
When the workpiece 1 is bent, the workpiece 1 returns to its original state due to springback, so the pushing tool 1
If the workpiece 2 is moved slightly upward after passing under the exit side end 11 and the workpiece 1 is bent by the pusher 12 at an acute angle smaller than the right angle, the workpiece 1 can be bent after the pusher 12 retreats. This is because the workpiece 1 is restored to the right angle by the spring bank.

It is one angle when divided into equal parts. Further, r is the radius of curvature of the curved portion.

2, and an operating mechanism 23 is connected to one of the screw shafts 20. By rotating the screw shafts 20 and 21 in the forward or reverse direction by the operating mechanism 23, the pair of shapes 10 and 10 can be brought closer or separated. The configuration is such that

．． The mutual spacing of 10 is adjusted to the outer diameter dimension of the round pipe material.

である。By the way, when the workpiece 1 is a round pipe material, a shape material 10.10 having the same shape as when bending a plate material 1°, that is, a shape material 10.10 with a flat surface facing the round pipe material as shown in FIG. When using , only one point on the circumferential surface of the round pipe material is pressed against the flat outlet side end 11 of the shape material 10 by the pushing tool 11, and the inner part of the round pipe material, that is, the part compressed by bending, is pressed at one point on the circumferential surface of the round pipe material. The pressing force may be concentrated locally and the workpiece 1 may not bend properly, and may become distorted and bent. In order to avoid such concerns, as shown in FIGS. 4 and 5, the periphery of the outlet 14 of the mold material 10.10 should be aligned with the outer peripheral surface of the round pipe material 1'' to form an arcuate molding surface 15. By doing so, the half circumferential portion of the round pipe material 1'' is bent while being supported by the forming surface 15, so that the above-mentioned local concentration of pressing force does not occur, and the round pipe material 1'' is bent. This is particularly advantageous when bending the round pipe material 1'' at a large angle.

に好適に使用できる。FIG. 6 is an explanatory diagram showing the case of bending a round pipe material 1'' into a special shape. In this case, the round pipe materials 1 and 2 are intermittently fed out from the outlet 14 of the mold material 10 (see Figure 1a, etc.), and the round pipe materials IIT are held at a desired angle around their axis by rollers, etc. By rotating the round pipe material 1'' intermittently and moving the pushing tool 12 by a certain width when the delivery and rotation of the round pipe material 1'' is stopped, the round pipe material 1'' is shaped like the shape material 10. The pipe is pressed against the outlet end 11 (see Fig. 1a, etc.) and bent by a certain angle. Even if the feeding and rotation of the round pipe material 1'' are carried out simultaneously, one is done first and then the other is bent. You may go. If the round pipe material 1'' is rotated by the same angle at each bending point 92 as shown in Fig. 6, the bent round pipe material I IT will be spirally shaped as shown in Fig. 7. It can be suitably used, for example, as a handrail for a spiral staircase.

When bending other bending points, use round pipe material I.
Bending into a curved shape without twisting is performed without rotating II.

るパイプ材の曲げ加工方法。[Claims] 1. Using a pair of molded materials whose mutual spacing can be adjusted to match the thickness or outer diameter of a workpiece such as a plate material or pipe material, and whose exit side end is tapered; The above-mentioned workpiece is intermittently fed out from the outlet of a pair of molds whose outlet width is adjusted according to the thickness or outer diameter of the workpiece, and when the feed of the workpiece is stopped. . A method for bending a plate or the like, characterized in that the workpiece is pressed against the exit side end of the mold material and bent by a certain angle by moving a pushing tool by a certain width. 2. The round pipe material is intermittently fed out from the outlet of the molded material whose exit side end is tapered and the peripheral edge of the exit is formed into an arcuate forming surface, and the feeding of the round pipe material is stopped. A method for bending a pipe material, comprising: pressing the round pipe material against the forming surface and bending the pipe material by a certain angle by moving a pushing tool by a certain width while the pipe material is being bent. 3. The round pipe material is intermittently fed out from the exit of the mold material, the round pipe material is intermittently rotated by a desired angle around its axis, and the feeding and rotation of the round pipe material are stopped. A method for bending a pipe material, the method comprising: pressing the round pipe material against the exit side end of the mold material and bending the pipe material by a certain angle by moving a pushing tool by a certain width.
