BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire bending and straightening device including iron wires and electric wires.

[0002]

2. Description of the Related Art In an electric wire processing machine for handling a wire, for example, an electric wire, the electric wire is cut into a predetermined length, the coating at the cut end is peeled off, and then the terminal is crimped to the cut end. ing.

The electric wire to be processed is usually brought in from the manufacturer in the form of a package wound around a reel or bundled in a ring and tied with a string.

Therefore, when the electric wire is unwound from the packaged shape, the electric wire has many bends, so that a correction device for removing the bend has been conventionally used (for example, Japanese Utility Model Laid-Open No. 2-87329). (See) was used.

This correction device includes a flat plate body, a comb-shaped bracket slidably provided on the plate body, a plurality of plate-side guide rollers erected on the plate body, and a comb-shaped bracket. By providing the bracket-side guide roller standing upright, the feeding paths for bending the wire rod are formed in a plurality of rows.

[0006] When the diameter of the wire rod that bends and bends is changed, the comb-shaped bracket is slid on the plate body, so that the gap for bending and bending formed by the plate-side guide roller and the bracket-side guide roller is Each row can be adjusted at the same time.

[0007]

However, since the above-described conventional straightening device cannot perform the individual adjustment of the spacing for each row, a prompt response is required when wires having different diameters are handled in each row. There was a problem that I could not.

In view of such conventional circumstances, the present invention is capable of adjusting the interval for each wire rod feeding line, and at the time of wire rod replacement, each roller of each wire rod feeding line can be opened and closed at the same time. The purpose is to provide a gusset correction device.

SUMMARY OF THE INVENTION A wire rod curving straightening device of the present invention is a straightening device in which a plurality of wire rod feeding lines are formed in parallel with each other and the wire rods that enter the respective wire rod feeding lines are bent. There, a fixed plate arranged along the wire rod feeding line, a plurality of rows of fixed side rollers provided on the fixed plate, movable plates arranged along the wire rod feeding line on both sides of the fixed plate, The movable side roller provided on each movable plate, the movable block on which each movable plate is slidably held, and the interval between each movable side roller and each fixed side roller can be individually adjusted. Therefore, in order to be able to open and close the gap adjusting mechanism interposed between each movable plate and each movable block and each movable side roller with respect to each fixed side roller at the same time, It is made of a block switching mechanism which is bridged between the movable block.

[0010]

The distance between the fixed side roller and the movable side roller is individually adjusted by each distance adjusting mechanism.

The movable side rollers are simultaneously opened and closed with respect to the fixed side rollers by a block opening / closing mechanism.
