Background

Patent document with publication number CN 211803548U discloses a high-efficiency wire bending device, which comprises a plurality of device main bodies, wherein the device main bodies comprise processing elbows, fixing bases and rotating shafts, and the processing elbows are rotatably connected together through the rotating shafts and the fixing bases. When high-efficient curved line equipment carries out the curved line operation, cylinder assembly promotes drive mechanism to drive pivot rotary motion, the pivot drives processing elbow rotary motion, thereby will with the elbow bellying butt treat that the processing wire rod is bent into certain angle.

According to the wire bending equipment, the wire is placed on the wire cushion seat and the positioning mechanism in advance, the first groove is formed in the processing elbow, the second groove is formed in the wire cushion seat, the wire cushion seat is located below the rotating shaft and must keep a certain gap with the rotating shaft, and the gap allows the wire to be placed on the wire cushion seat in advance. Since the wire is placed on the wire pad in advance, the clearance between the wire pad and the rotating shaft is at least equal to the outer diameter of the wire, and the wire is allowed to pass through. In addition, because the second groove on the wire pad is used for accommodating the wire, after the wire falls into the second groove, a large gap is formed between the wire and the rotating shaft, the gap is larger than the outer diameter of the wire, and the gap prevents the wire from abutting against the rotating shaft. When the elbow is used for bending the wire rod, the wire rod is bent around the rotating shaft, and a larger gap exists between the wire rod and the rotating shaft, so that the bending angle of the wire rod is influenced, and the bending angle of the wire rod is inaccurate.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the accuracy of the wire bending angle of the wire bending equipment is improved.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a multistation curved line equipment, which comprises a fixed pedestal, the positioning mechanism of setting on unable adjustment base, install the pivot on unable adjustment base, install the epaxial processing elbow of changeing, the pivot can be rotatory relatively unable adjustment base, the last rotatory drive assembly of drive pivot that is equipped with of unable adjustment base, drive assembly includes the cylinder, the rack of being connected with cylinder piston rod, gear with rack toothing, the one end at the pivot is installed to the gear, one side of rack is equipped with the round pin spare, round pin spare and curve slot cooperation, the curve slot is seted up on a lateral wall of wire rod base, the bottom of wire rod base is equipped with the guide way, movable fit has the guide block in the guide way, the guide block is vertical to be fixed unable adjustment base is last.

The wire to be bent is placed on the wire cushion seat and the positioning mechanism and penetrates through a gap between the rotating shaft and the wire cushion seat. The air cylinder drives the rack to linearly displace, the rack drives the gear to rotate, the gear drives the rotating shaft to rotate, the rotating shaft drives the machining elbow to upwards rotate, and the machining elbow upwards bends the wire.

And in the process of driving the rack to linearly displace by the cylinder, the pin piece on the rack is matched with the curve groove and displaces along the curve groove. Because the rack linearly and horizontally displaces and the trend of the curved groove has a curved path, under the guidance of the guide groove and the guide block, the pin piece drives the wire material cushion seat to ascend through the curved groove, so that the wire material on the wire material cushion seat is close to the rotating shaft. When the wire rod is drawn close, the rack with linear displacement drives the rotating shaft to rotate through the gear, and the processing elbow bends the wire rod.

Because when processing the elbow wire rod of bending, the wire rod base is drawn close wire rod on it to the pivot, consequently, the utility model discloses a line bending equipment can improve the degree of accuracy of wire rod angle of bending.
