In addition, when the inclined surface 31 described above is a curved surface having a curvature, the first and second pressing blocks 55a and 55b described later in accordance with the curvature are not proportional to the distance from which the upper body 10T descends. The displacement amount changes, and according to this change, more various types of bending can be performed.

That is, the pin 103 is made of a metal material, and when it is bent by the bending machine 10, it is bent due to plastic deformation, but is restored within the elastic limit range, so that the bending degree is bent to bend more in consideration of the degree of restoration. Done.

That is, the above-described second draft angle b is formed to be inclined by an amount of return which can be calculated by the physical properties of the pin 103, in particular, the elastic modulus, and the angle at which the pin 103 is bent is a finished product. The second draft angle b is further required when being bent at an angle greater than approximately 90 °.

On the other hand, the bending of the pin 103 can be bent 1 ° to 5 ° more than the angle of the completed state, and when explained more loosely, for example, the bending angle of the pin 103 is 90 in the finished product. The second gradient angle b described above when bent at ° may be 91 ° to 95 ° with 1 ° to 5 ° inclined further.

Then, when the upper body 10T is lowered and the upper body 10T and the lower body 10B come into contact with each other, the socket brackets 100R and 100L are the third and fourth bracket mounting parts 73a of the upper bending block 70. In addition to being respectively accommodated in 73b, the socket tube 102 is disposed in the third and fourth bracket socket grooves 74a and 74b.

If the upper body 10T continues to fall further, the first, second, third and fourth compression springs 28a, 28b, 82a and 82b described above are compressed while the upper body 10T and the lower bend are compressed. The block 20 is lowered, and the sockets of the socket brackets 100R and 100L touch the first and second bending rollers 15a and 15b disposed on the lower body 10B so that the socket tube 102 is bent. This is done.
