The drive module 22 is a linear module, but other linear drive mechanisms may be used instead.
The method of use of the adjustment mechanism is described below.
When the wire storage cylinder 23 rotates forwards or reversely, once the tension sensor 17 detects that the tension of the molybdenum wire deviates from the preset value, the detection system of the cutting machine starts the stepping motor 6, and the whole driving module 22 starts to move upwards or downwards. Meanwhile, the driving module 22 drives the combined support 4 and the lower insulating base 18 to move synchronously, the lower insulating base 18 drives the tension sensor 17 and the upper insulating base 16 to move synchronously, and the upper insulating base 16 drives the whole guide wheel support 20 to move synchronously. The upward movement or downward movement of the guide wheel bracket 20 drives the upper tension wheel 15 and the lower tension wheel 21 to synchronously move longitudinally, so that the tension of the molybdenum wires wound on the upper tension wheel 15 and the lower tension wheel 21 is accurately changed.
Wherein, the tension sensor 17 receives the tension in two directions of the upper insulating base 16 and the lower insulating base 18, and the detection system of the cutting machine takes the average value of the sum of the upper tension and the lower tension as a sampling numerical value to adjust the tension.
When the wire storage cylinder 23 rotates forwards or backwards, the tension of the molybdenum wires on the wire storage cylinder 23 is different, the tension sensor 17 can monitor the unidirectional tension of the wire storage cylinder 23 during the forward rotation or the backward rotation, the adjustment is accurate and reliable, the tension of the molybdenum wires on the wire storage cylinder 23 during the forward and backward rotation is detected consistently, and the machining precision and the machining reliability of the wire cut electric discharge machine are greatly improved.
Wherein the initial contact switch 10 ensures the maximum elevation height, i.e., the highest point, of the displacement detection rod 7 and the idler pulley bracket 20. The limit contact switch 12 ensures the maximum lowering height, i.e., the lowest point, of the displacement detection rod 7 and the guide wheel frame 2.
In the processing process, the molybdenum wire stretches back, the displacement detection rod 7 and the guide wheel support 2 automatically descend to ensure that the tension is constant, when the displacement detection rod and the guide wheel support descend to the lowest point, the indicating lamp is turned on, and the horn gives an alarm to prompt a user. At this time, the user moves the molybdenum wire to one end of the wire storage drum 23, removes the molybdenum wire and holds it by hand, and presses the elevation switch to adjust the displacement detection rod 7 and the idler pulley bracket 2 to an optimum position, which is the optimum point, and the switch at this point is the optimum point switch 11.
Since the tension sensor 17 has a weight, the pressure generated by the weight will cause the voltage signal output by the sensor to be inaccurate, and measurement errors are caused. Therefore, the tension sensor 17 includes a tension zero regulator 24 for regulating an initial output voltage of the tension sensor 17, and an output voltage of the tension zero regulator 24 is used to compensate for a deformation amount caused by the own weight of the tension sensor 17. As will be described further below.
As shown in fig. 10, the theoretical relationship between the amount of deformation of the tension sensor 17 and the output voltage is shown.
As shown in fig. 11, the actual relationship between the amount of deformation of the tension sensor 17 and the output voltage is shown. At this time, the K section is an output voltage caused by the self weight of the tension sensor 17.
As shown in fig. 12, it is a relationship diagram of the deformation amount of the tension sensor 17 and the output voltage after being compensated by the tension zero regulator, and the section S is the increased compensation voltage or the offset voltage.
As shown in fig. 13, which is a schematic structural diagram of the zero-point tension adjuster 24 of the present invention, the zero-point tension adjuster 24 is an adding circuit. In particular, the resistance is chosen such that R1= R2= R = RF, then U0= Ui1+ Ui2 where: ui2 is an artificially set value, the value is equal to a voltage value generated by the sensor due to self weight, and the value is adjustable and used for overcoming the discreteness error of the sensor.
Fig. 14 is a schematic diagram showing the module connection of the constant tension control mechanism for a molybdenum wire of a wire-cut electric discharge machine according to the present invention. The tension sensor 17 is installed in the molybdenum wire drive mechanism P3. The tension of the molybdenum wire P6 generates a voltage signal. The voltage signal passes through the amplifying and shaping circuit P2 to generate a voltage signal proportional to the variation. The central control system P5 issues a command code to form a set voltage. The comparison circuit P4 compares the set voltage with the voltage signal of the tension sensor 17, and the molybdenum wire driving mechanism P3 starts to rise or fall, so that the tension of the molybdenum wire P6 on the molybdenum wire connector P1 is constant.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
