BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lattice bar manufacturing apparatus, and more particularly, to a lattice bar manufacturing apparatus that automatically bends a main wire into a zigzag shape while simultaneously transporting three types of wire, The automatic lattice bar automatic manufacturing apparatus according to the present invention can automatically and precisely cut a predetermined size of a lattice bar.

Generally, a lattice bar is inserted into a concrete in a building to increase the strength of the building. As the concrete is put together with the concrete, the lattice bar can firmly support the concrete and increase the strength.

The lattice bar is folded in the form of a zig-zag, such as an N-type W, and is laid with the concrete.

Such a lattice bar is manufactured by directly bending each bending portion by manual operation of a work force, so that the operation time is delayed and there is a problem that a large amount of lattice bars can not be manufactured.

In order to solve the above-mentioned problem, a bending machine capable of bending a reinforcing bar at a certain angle has been used so that the worker can bend without applying great force.

However, even if the bending machine is used, the work force is always required, and the angles and intervals to be bent are not constant as the worker directly works, resulting in inaccurate problems.

In order to solve the above-mentioned problem, in the prior art 1 (automatic continuous continuous lathing machine of the lattice and the lattice continuous formed body manufactured thereby), a plurality of intermeshing conveying rollers are provided, And pressurizes and presses it.

However, since it is possible to bend the steel bar up and down, and the worker has to cut the steel bar manually at a certain length, the work force is indispensable.

In addition, it is difficult to cut and set the length accurately, and in order to cut the length to the standard, there is a problem that the length must be separately measured.
