ていたものである。In the above publication, a C-shaped member 31 having an upper bending blade and a lower bending blade attached thereto is fixed to the tip of a rocker arm 32 as shown in FIG. The rocker arm is swingably attached to the bending machine main body via an eccentric member 33, and an actuator 34 is attached to the eccentric member to rotate the eccentric member. Then, the actuator is actuated to rotationally displace the rocker arm 32 to horizontally displace the upper bending blade or the lower bending blade.

の欠点があった。[Problems to be Solved by the Invention] Therefore, in the conventional one, when the rocker arm 32 is swung in the work approach direction to perform the bending process in consideration of the spring back, the C-shaped member 31 and the rocker arm are formed.
The reaction force in the horizontal direction and the rotational force A in the direction of the arrow at the joint with 32
Is added (Fig. 8). Therefore, the strength of the joint is
The design must be large enough to withstand the above bending loads that occur during processing and to prevent damage to the machine. Therefore, the joint portion and the rocker arm body are restricted in strength and material, and often require a reinforcing member, which has a drawback that the cost and the weight of the apparatus are increased.

を提供することを目的とする。In view of this, the present invention eliminates the conventional welded structure in which the C-shaped member and the rocker arm are fixed to each other, and interposes the rolling member between the two members, so that a considerable slip between the two members is achieved. Is a structure that can allow. Therefore, it is an object of the present invention to provide a bending machine in which only a horizontal reaction force is applied to a rocker arm and no rotational force is applied during overbend processing.

The upper die 5 and the lower die 3 hold down the work. Next, when bending the tip edge of the work upward by 90 °, use cylinders CY 2 and C
When Y 3 is simultaneously driven to raise the C-shaped member 9, the edge of the work is bent upward at a right angle by the upward bending movable blade 10b. On the contrary, when bending downward, when the C-shaped member is lowered, it is bent downward by the downward bending movable blade 10a.

加工を行なう。In this case, in order to drive the overbend setting mechanism 22, the C-shaped member 9 is raised to the upper limit, the piston rod of the cylinder CY 4 is extended, and the shaft 25 is rotated by a predetermined amount by the crank. Then, the holding arm 21 is advanced toward the upper and lower molds 3 and 5 by rotating the eccentric member 23 about the shaft by a predetermined angle. A rolling member consisting of a ball or a roller member 20 that rotates in contact with the rear surface of the C-shaped member is attached to the tip of the holding arm, and the tip of the holding arm is regulated by a guide so as not to be displaced vertically. Therefore, when the holding arm 21 advances toward the upper and lower molds 3 and 5, the C-shaped member 9 swings toward the work approach side around the guide roller 15 provided between the fixed rails 13 therebelow. That is, when the C-shaped member 9 reaches the upper limit, the guide roller 15 attached to the lower part of the tuna 17 is constrained between the lower fixed rails 13, 13 while the guide roller 15 attached to the upper part of the tuna is fixed rail. It is located on the movable body 14 arranged in the notch at the terminal end. Since the movable body is elastically held by the pulling 18 and can be depressed toward the work approach side, the upper guide roller 15 is released from the constraint and becomes free. In this state, when the rolling element 20 is brought into contact with the rear surface of the C-shaped member 9 and pushed backward by the holding arm 21, the C-shaped member is swung toward the work approach side, and an acute angle bending in consideration of spring back is performed. When bending down, C
The mold member is lowered to the lower limit, the upper guide roller is restrained, the lower guide roller is set in a free state, and the C-shaped member is swung toward the work approach side to perform bending work.

力がかかるのを防ぐことができる。The bending reaction force of the material generated during bending is transmitted to the holding arm 21 from the C-shaped member 9 to which the upper blade or the lower blade is attached,
A component force in the horizontal component force normal direction is generated at the bent portion between the C-shaped member and the holding arm. The component force in the horizontal direction is supported by the holding arm 21, and the component force in the normal direction escapes as a slip between the rolling element 20 and the C-shaped member 9, so that an unreasonable force is applied to the holding arm and the C-shaped member. Can be prevented.
