[0024] In this embodiment, the power supply device main body 2 includes: Main oscillation circuit: A 4MHz crystal oscillator is used to generate the main frequency pulse, and two square wave pulses of 250kHz and 62.5kHz are output through the frequency division circuit to provide a reference pulse signal for the system; Pulse width adjustment circuit: Four single-pole single-throw switches are used to select different RC time constants to control the duration of the discharge pulse; Interval adjustment circuit: Adjust the rest time between the discharge pulses, and control the number of discharges per unit time by changing the duty cycle; Power amplification circuit: Transistors or field effect transistors are used to amplify the power of the adjusted pulse signal, and the output current is increased to the tens of amperes level to meet the requirements of discharging and eroding metals; Rectifier power supply: It includes a three-phase full-wave rectification circuit and filtering elements, which convert 380V alternating current into 80 - 100V direct current to provide stable energy for the entire pulse power supply system; In this embodiment, the connection wire harness of the power supply device main body 2 is connected to one of the commutation rollers 20. Since the electrode wire 22 is arranged on the commutation roller 20, when the electrode wire 22 passes through the commutation roller 20 with pulsed electric energy, a spark discharge will be formed at the electrode wire 22; It is a mature existing technology and will not be elaborated here; For example, as Figure 3 shown, the wire cutting assembly 6 includes: The displacement plate 13 is threadedly connected to the outside of the transmission screw 4. One end of the displacement plate 13 is fixedly connected to the positioning seat 14. The top and bottom of the inner side of the positioning seat 14 are respectively rotatably connected to the unwinding roller 15 and the winding roller 16. One end of each of the unwinding roller 15 and the winding roller 16 is fixedly connected to a linkage spur gear 17, and the two linkage spur gears 17 are meshed; The positioning strip 18 is fixedly connected to one end of the positioning seat 14. The bottom of one end of the positioning strip 18 is fixedly connected to the guiding frame 19. Both ends of the guiding frame 19 are rotatably connected to a plurality of commutation rollers 20. A tension adjustment assembly 21 is arranged in the middle of the positioning strip 18. The electrode wire 22 is wound around the outside of the unwinding roller 15, and the end of the electrode wire 22 away from the unwinding roller 15 passes through the tension adjustment assembly 21 and a plurality of commutation rollers 20 in sequence and is fixedly connected to the winding roller 16; The transmission assembly is assembled inside the support frame 3 and is used to obtain the power of the drive motor 5 to drive the unwinding roller 15 to rotate.

[0025] For example, as Figure 3 shown, the transmission assembly includes: The linkage shaft rod 23 is vertically rotatably connected inside the support frame 3. At the top of the linkage shaft rod 23 and the top of the outer side of the transmission screw rod 4, linkage sprockets 24 are fixedly connected, and the two linkage sprockets 24 are connected by a chain; The hollow shaft rod 25 is vertically rotatably connected to one end of the displacement plate 13 close to the linkage shaft rod 23, and the hollow shaft rod 25 is also slidably connected to the outer side of the linkage shaft rod 23. A transmission bevel gear 26 is fixedly connected to the outer side of the hollow shaft rod 25. One end of the unwinding roller 15 close to the transmission bevel gear 26 is fixedly connected with a mating bevel gear 27, and the mating bevel gear 27 is meshed with the transmission bevel gear 26.

[0026] For example, as Figure 3 shown, a limiting strip 28 is fixedly connected to the outer side of the linkage shaft rod 23, a limiting groove is formed in the inner wall of the hollow shaft rod 25, and the limiting strip 28 is slidably connected inside the limiting groove. Through the structural cooperation of the limiting strip 28 and the limiting groove, when the displacement plate 13 is vertically displaced, the hollow shaft rod 25 can follow the displacement under the guidance of the limiting strip 28, and when the linkage shaft rod 23 rotates, since the limiting strip 28 is inside the limiting groove, the hollow shaft rod 25 can follow the linkage shaft rod 23 to rotate.

[0027] For example, as Figure 4 shown, the tensioning and adjusting assembly 21 includes: The positioning ear 29 is fixedly connected to the middle of the positioning strip 18. An adjusting screw rod 30 is vertically rotatably connected inside the positioning ear 29. A displacement ear 32 is threadedly connected to the outer side of the adjusting screw rod 30. One end of the displacement ear 32 is rotatably connected with a tensioning and adjusting roller 33, and the electrode wire 22 is laid on the top of the tensioning and adjusting roller 33.

[0028] For example, as Figure 5 shown, a linear guide rod 31 is fixedly connected to the inner side of the positioning ear 29, and the displacement ear 32 is also slidably connected to the outer side of the linear guide rod 31; For example, as Figure 6 shown, the feeding assembly 7 includes: The transmission seat 34 is fixedly connected to the top of the bearing plate 1. A pushing screw rod 35 is rotatably connected inside the transmission seat 34. A pushing frame 36 is threadedly connected to the outer side of the pushing screw rod 35. A linear guide rail 37 is fixedly connected to the top of the pushing frame 36. Adjusting frames 38 are slidably connected to both ends of the linear guide rail 37, and positioning clamping plates 39 are fixedly connected to the two adjusting frames 38; An electric push rod 40, the electric push rod 40 is fixedly connected to the top of one side of the push frame 36, the output end of the electric push rod 40 is fixedly connected to a push plate 41, both ends of the push plate 41 are rotatably connected to push rods A42, and the ends of the two push rods A42 away from the push plate 41 are rotatably connected to the two adjustment frames 38 respectively; A carrying ear 43 is fixedly connected to one end of the transmission seat 34, and one end of the carrying ear 43 is fixedly connected to a driving motor 44, and an output end of the driving motor 44 is fixedly connected to a rotating shaft 45, and one end of the rotating shaft 45 is provided with a detachable incomplete gear 46, and one end of the pushing screw 35 is fixedly connected to a matching spur gear 49, and the incomplete gear 46 is meshingly connected with the matching spur gear 49.

[0029] For example, Figure 8 As shown, one end of the incomplete gear 46 is fixedly connected to an assembly rod 47, and the ends of the assembly rod 47 and the rotating shaft 45 that are close to each other are fixedly connected to a quick-mount flange 48, and the rotating shaft 45 and the assembly rod 47 are connected by the quick-mount flange 48. Through the setting of the quick-mount flange 48, the incomplete gear 46 can be easily replaced while ensuring the transmission stability of the incomplete gear 46.

[0030] For example, Figure 6 As shown, the top of the positioning clamp plate 39 is an arc-shaped structure, and the inner side of the top of the positioning clamp plate 39 is provided with anti-slip grooves. Through the structural characteristics of the top of the positioning clamp plate 39, it can contact the bolt rod over a larger range, and combined with the setting of the anti-slip grooves, the friction between the positioning clamp plate 39 and the bolt rod can be increased to prevent the bolt rod from loosening.

[0031] For example, Figure 6 As shown, one end of the transmission seat 34 away from the mounting ear 43 is fixedly connected with a stabilizing plate 50, and a plurality of alloy balls 51 are arranged on the inner side of the stabilizing plate 50. Through the arrangement of the stabilizing plate 50, the bolt rod can be auxiliary supported to prevent the bolt rod from jumping up and down.

[0032] For example, Figure 9 As shown, the receiving assembly 12 includes: A limiting rod 52, the limiting rod 52 is fixedly connected to the bottom end of the receiving frame 8, a guide plate 53 is slidably connected to the outer side of the limiting rod 52, and a coil spring 54 is fixedly connected between one side of the guide plate 53 and the receiving frame 8; A compression rod 55, the compression rod 55 is vertically slidably connected to the top of the receiving frame 8, the bottom end of the compression rod 55 is fixedly connected to a conducting plate 56, one end of the conducting plate 56 is rotatably connected to a push rod B57, and the end of the push rod B57 away from the conducting plate 56 is also rotatably connected to the guide plate 53; The baffle plate 58 is fixedly connected to the top end of the guiding plate 53. A blanking notch 59 is formed at one end of the baffle plate 58 close to the guiding plate 53.

[0033] Working principle: First, place the bolt rod between the two positioning clamping plates 39. Then start the electric push rod 40 to push the pushing plate 41 upward. Since the push rod A 42 is connected between the pushing plate 41 and the adjusting frame 38, when the pushing plate 41 moves vertically, it can pull the adjusting frame 38 through the push rod A 42, causing the positioning clamping plates 39 to approach the bolt rod until the bolt rod is positioned between the two positioning clamping plates 39. Start the driving motor 44 to drive the incomplete gear 46 to rotate by means of the rotating shaft 45. In accordance with the structural characteristics of the incomplete gear 46, the incomplete gear 46 will intermittently connect with the driven spur gear 49. When the driven spur gear 49 meshes with the driven spur gear 49, it can drive the pushing screw rod 35 to rotate. Under the connection between the pushing screw rod 35 and the pushing frame 36, the pushing frame 36 will linearly displace along the pushing screw rod 35. When the incomplete gear 46 disengages from the driven spur gear 49, the pushing screw rod 35 will stop rotating. Since the moving distance of the pushing frame 36 is the same each time the incomplete gear 46 toggles the driven spur gear 49, the fixed-length pushing of the bolt rod can be realized. And when the length to be pushed changes, separate the two quick-installation flanges 48, then the incomplete gear 46 can be disassembled, and then replace the incomplete gear 46 with the corresponding number of teeth to control the pushing length of the pushing frame 36. The electrode wire 22 is as Figure 5 shown, passes through the tension adjusting roller 33 and a plurality of commutation rollers 20 in sequence and is connected to the winding roller 16. The adjusting screw rod 30 can be rotated. Under the connection between the adjusting screw rod 30 and the displacement ear 32, the displacement ear 32 can displace along the adjusting screw rod 30. Since the electrode wire 22 is arranged on the tension adjusting roller 33, the tension of the electrode wire 22 can be controlled by vertically adjusting the tension adjusting roller 33. Start the driving motor 5 to drive the driving screw rod 4 to rotate. Under the connection between the driving screw rod 4 and the displacement plate 13, the displacement plate 13 can vertically displace along the driving screw rod 4, driving the electrode wire 22 to approach the bolt rod. And provide a pulsed power supply to the electrode wire 22 through the power supply device main body 2, causing a spark discharge to be formed between the electrode wire 22 and the bolt rod. A large amount of heat is instantaneously generated in the spark channel, melting the bolt rod by heating. And under the linkage of the chain, the power of the transmission motor 5 can be transmitted to the linkage shaft rod 23, so that the linkage shaft rod 23 drives the hollow shaft rod 25 to rotate synchronously, and the transmission bevel gear 26 drives the matching bevel gear 27, thereby driving the unwinding roller 15 to rotate, and through the connection between the two linkage spur gears 17, the power of the unwinding roller 15 can be transmitted, so that the winding roller 16 can rotate in the opposite direction, so that the electrode wire 22 can be released by the rotation of the unwinding roller 15, and the electrode wire 22 can be wound up by the rotation of the winding roller 16. Through the contact between the electrode wire 22 and the bolt rod at different positions, the tension of the electrode wire 22 during operation can be guaranteed, and the operation accuracy of the electrode wire 22 can be guaranteed; At the same time, when the displacement plate 13 moves downward, the displacement plate 13 will contact with the pressure rod 55. As the displacement plate 13 continues to move downward, the pressure rod 55 can push the conductive plate 56. Since the push rod B57 is connected between the conductive plate 56 and the guide plate 53, when the conductive plate 56 moves, the push rod B57 can push the guide plate 53 to cause the baffle plate 58 to move toward the U-shaped frame 11. After the electrode wire 22 cuts the bolt rod, the cut bolt rod will be located on the inner side of the U-shaped frame 11. When the unloading notch 59 moves to the bottom of the U-shaped frame 11, the bottom of the U-shaped frame 11 loses its blockage, causing the bolt rod to fall to the mounting frame 9 and be transmitted to its end through the mounting frame 9. When the guide plate 53 is displaced, the coil spring 54 can be stretched. When the displacement plate 13 is separated from the pressure rod 55 , the guide plate 53 can be pulled back to its original position by the coil spring 54 , so as to block the U-shaped frame 11 through the baffle plate 58 .

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
