A second gear is freely mounted to the input shaft and driven by a second servo motor. A box having two pairs of rollers is connected between the input shaft and an output shaft and the wire is rolled forward by the rollers. A first auxiliary gear is co-axially is co-rotatably connected to the second gear and drives the rollers on the box. The auxiliary gear is driven by a third servo motor. The input shaft and the output shaft are rotated independently from the box.
Description
- The present invention generally relates to a spring manufacturing device that has a box co-rotatably connected to a shaft so that the wire is clamped whole the box is rotated.
- Conventional spring manufacturing device utilizes several pairs of rollers to send a wire and an end of the wire is sent to an operation section on which a lot of forming members are located. The end of the wire is then bent to a desired angle and the wire is then scrolled on a mandrel to form a coil spring. The other end of the wire is also be bent to have a desired angle. The operation section has many pairs of forming members so as to bend the wire to different angles. However, it is difficult to bend the wire to a small angle if the operation section has too many forming members thereon. An improved wire device has a rotary device which is cooperated with a computer to rotate the wire at a preprogrammed angle and one of the pairs of forming members are activated to bend the wire. By this way, a small angle on the wire can be done. Nevertheless, the rollers sending the wire have to release the wire when the wire is rotated. Similarly, when sending the wire by the rollers, the rotary device has to be stopped. This is not efficient for production. Besides, the wire could shift if no rollers retain the wire when the wire is rotated and the shift of the wire results an un-precise product.
- This invention has been made to overcome the above mentioned drawbacks of a conventional spring manufacturing device and comprises an input shaft through which a wire extends and a first gear is fixedly mounted to the input shaft which is driven by a first servo motor. A second gear is freely mounted to the input shaft and driven by a second servo motor. A first auxiliary gear is co-axially and co-rotatably connected to the second gear. A box has an end thereof connected to an end of the input shaft and two first rollers and two second rollers are connected to the box. The other end of the box is connected to an output shaft and a third gear is co-axially connected to the output shaft. A fourth gear is engaged with the auxiliary gear and a driving shaft extends from the fourth gear and is inserted into the box. The driving shaft drives the two first rollers and the two second rollers. A third servo motor drives the third gear.
- The primary object of this invention is to provide a spring manufacturing device wherein the wire is still controlled by the rollers while it is rotated.
- The foregoing and other objects, features, aspects and advantages of the present invention will become better understood from a careful reading of a detailed description provided herein below with appropriate reference to the accompanying drawings.
- FIG. 1 is a side view to show the spring manufacturing device of the present invention, wherein two pairs of rollers on the box are shown;
- FIG. 2 is a side view to show the spring manufacturing device of the present invention, wherein a set of guide rollers are shown;
- FIG. 3 is a side view to show the spring manufacturing device of the present invention, wherein three servo motors are shown;
