Working handpiece of numerical control wire bending machine

Abstract

The invention relates to a working handpiece of a numerical control wire bending machine, which comprises the working handpiece of the numerical control wire bending machine. Two die heads in the die-changing and die head steering lifting position-hiding mechanism in the numerical control wire bending machine are connected with two spline shafts without relative displacement; the bottom parts of the spline shafts are contacted with the lower end of a pressure spring; the upper end of the pressure spring is contacted with the inner step of a main shaft and drives the spline shafts to move downwards; a swing arm of the position changing and swinging mechanism of the bending die head in the numerical control wire bending machine is connected with a wire bending power driving device without relative displacement; one end of a connecting rod is moveably connected with the swing arm, while the other end is moveably connected with the swing arm; the swing arm is connected with a rotating shaft of a numerical angle graduator without relative displacement; a driving device takes a worm-gear case as a main body; a worm is supported by a bearing without axial displacement, and at the same time drives two worm gears which are connected with the main shaft without relative displacement; splines are arranged in the main shaft; the spline shafts are connected with the splines in the main shaft; the main shaft and the worm-gear case are supported by the bearing without axial displacement; and two bending die heads are connected with the two spline shafts respectively without relative displacement.

Problems solved by technology

[0002] At present, in the structural design of the wire bending machines sold on the market, each die head corresponds to an oil cylinder or cylinder to push and pull separately, so as to realize die head change and turn to lift and avoid positions. The load on the head, the forming efficiency of the wire is low

[0003] The position change and positioning of the CNC bending die head is through the oil cylinder to push the pendulum, the signal detects the pause position, the action is correspondingly slow, and the accuracy of the die change and position angle is low

[0004] The bending mechanism of the CNC wire bending machine is driven by a reduction gear and a spur gear transmission. The structure of the transmission mechanism is complex, the load itself is heavy, and the forming efficiency of the wire is relatively low.

[0005] In the structural design of the wire cutting cylinder of the CNC wire bending machine, the single-push cylinder directly pushes the shearing die to perform shearing or the single-push cylinder combined with the slider pushes the shearing die to perform shearing. The shearing force of the wire is small and the volume of the cylinder Large, heavy head load, low wire forming processing efficiency
