New description: [New technical field] This is an improved mechanism for the control device of the spring outer diameter of a coil spring forming machine. The position of the outer diameter cutter head can be controlled by using an electromechanical device such as a servo motor. The spring machine can quickly and accurately set the size and produce the spring products needed. This creation's department uses two mathematical relative coordinates to replace the single absolute seat's positioning, combined with the application of a simple single-axis slide. Compared with the same type of machine, it can reduce one slide. Outside the organization, it simplifies the writing of control programs and speeds up the control of the size. [Prior Art] According to the conventional spring coil outer diameter control device of the coil spring forming machine, as shown in (1), there are two outer diameter symmetrical knives to control the forming size of the spring. On the XY two-axis slide table, the control unit χ, the power source on the γ axis • _ whole head inspection 'to complete the spring outside (four) size setting and control. Using this device, after determining the change in the outer diameter size, use the angle of the cutter head to the vertical or horizontal plane, use the trigonometric function to convert the new coordinate of the cutter head, calculate the change dimension of the X and the 轴 axis, and then add the center point. The position change length can only push the lamp shaft to correctly move the position of the two cutter heads. [New content] According to the above description, when considering the rapid change of the outer diameter of the production spring, the control computer 3 must always calculate the absolute position of the outer diameter cutter head and then control the movement of the knife shaft. The creator thinks about increasing the control speed. It can improve production efficiency and reduce production cost. The easiest way is to change the original absolute single-position positioning method to two relative coordinates, and then use a separate sliding table to control the linear motion on a single target. In addition to quickly controlling the position of the outer diameter cutter head, the vertical movement of the upper and lower cutter heads can be combined on the same slide table to reduce the mechanism of one slide. [Embodiment] Please refer to the figure (2). In this example, two outer diameter knives are taken as an example. First, a pedestal slide 00 is fixed on the main table, and the cutting and sending directions of the wire exit are set. Vertically, the upper and lower outer diameter knife slides 10 and 20 are simultaneously mounted on the slide plate of the base slide table, but are divided into two upper and lower non-overlapping holes, and the outer diameter knife slide 10 On the moon plate 2, the device has an outer diameter knife 13, and the outer diameter knife blade 20 of the slide plate 22 is also provided with an outer diameter knife 23, both of which point to the center of the spring at the same time. Point, forming an angle of about 9 degrees, and a triangle with the base slide. Each of the platforms has a servo motor as the power source of the slide table, and the inner connection H and the ball screw are connected, and the push plate is advanced or retracted through the screw, and each power source has a signal line and control. The controller is connected and the controller is connected to the control computer via another signal line. M403387 After the machine setting is completed, if you want to change the size of the outer diameter, just use the subtraction method to calculate the change length of the outer diameter of the spring. Half of this value (that is, the change length of the radius) is transmitted from the CNC computer to the controller, and the synchronous start is three. A sliding σ CNC motor a 'Pushing the slide plate through the ball screw, according to the direction of increasing or decreasing, the length of the forward or backward radius to be changed, the size setting can be completed', if the XY dual-axis slide table is used, The trigonometric function can be used to calculate the different advance and retreat lengths of each axis.
