Description

Technical Field

[0001] This utility model relates to the field of electromagnetic wire production technology, specifically to an electromagnetic wire straightening device. Background Technology

[0002] Electromagnetic wire is a conductive metallic wire with an insulated layer, mainly used for winding coils or windings in motors, transformers, electrical appliances, and other equipment. Its core principle utilizes Faraday's electromagnetic induction effect, generating a magnetic field through current or inducing current by cutting magnetic lines of force, thus achieving the mutual conversion of electrical energy and magnetic field energy. Before winding the electromagnetic wire onto the equipment surface, the wire needs to be straightened and flattened to facilitate subsequent winding. This requires electromagnetic wire straightening equipment. Existing electromagnetic wire straightening equipment often consists of multiple sets of straightening rollers and pressing rollers. Two rows of straightening rollers on the same mounting frame are staggered, and the straightening directions of adjacent sets of straightening rollers are not aligned. Similarly, two adjacent sets of straightening rollers are symmetrically distributed. The gap between the rollers can be changed by rotating the corresponding adjusting bolts to accommodate different specifications of electromagnetic wire. When the electromagnetic wire passes through the straightening rollers, the straightening rollers straighten the electromagnetic wire by their own limiting effect. Then, the straightening rollers press the electromagnetic wire into a suitable shape by their own pressure, which facilitates subsequent winding work. Traditional electromagnetic wire straightening equipment changes the gap between the rollers by rotating the corresponding adjusting bolts. Manually rotating the adjusting bolts will introduce errors, resulting in errors in the spacing between each set of rollers, which affects the straightening effect of the electromagnetic wire. Therefore, we propose an electromagnetic wire straightening device. Utility Model Content

When the first limiting post 556 and the second limiting post 557 are both located on the right side of the first limiting groove 554 and the second limiting groove 555, the distance between the first straightening wheel 52 and the second straightening wheel 53 increases, and vice versa, providing a basis for adjusting the electromagnetic wire straightening operation. The straightening mechanism 5 also includes a lead screw 558, which is rotatably connected to the upper left rear of the base 1. The outer surface of the lead screw 558... All are connected to the inner left middle thread of the adjusting plate 553. The left end of the lead screw 558 is equipped with a knob to provide a driving effect for the adjustment of the electromagnetic wire straightening work. It is equipped with a pressing mechanism 4 and a straightening mechanism 5, which can simultaneously and accurately adjust the distance between all the straightening wheels 1 52 and straightening wheels 2 53, and automatically change the gap between the pressing wheels 45, avoiding the error caused by manual adjustment and improving the straightening effect of the electromagnetic wire. A corrugated tube 3 can be provided between the right side of the step at the upper left rear of the base 1 and the left side of the adjusting plate 553, so that the corrugated tube 3 is sleeved on the outside of the lead screw 558. The corrugated tube 3 adapts to the extension and retraction as the adjusting plate 553 moves, and the corrugated tube 3 provides an external protective barrier for the lead screw 558.

[0027] The working principle of the electromagnetic wire straightening device provided by this utility model is as follows: When straightening the electromagnetic wire, first pass the electromagnetic wire between the first straightening wheel 52 and the second straightening wheel 53, and then pass it between the two sets of straightening wheels 45. Then, adjust the work according to the actual situation. First, adjust the distance between the straightening wheels 45. The single-chip microcomputer 7 controls the second motor 47 to run. The output shaft of the second motor 47 drives the worm 44 to rotate. Because the worm wheel 43 is meshed with the worm 44, the worm wheel 43 also rotates, driving the bidirectional lead screw 42 to rotate. Since the inside of the slider 41 is threaded to the outer surface of the vertically adjacent bidirectional lead screw 42, the two vertically adjacent sliders 41... The rollers move inward synchronously, causing the corresponding straightening rollers 45 to also move inward synchronously until the two vertically adjacent straightening rollers 45 reach a suitable distance, thus completing the distance adjustment of the straightening rollers 45. Then, the distance between straightening roller 1 52 and straightening roller 2 53 is adjusted. Turning the knob drives the lead screw 558 to rotate. Because the outer surface of the lead screw 558 is connected to the inner left middle thread of the adjusting plate 553, the adjusting plate 553 moves to the left as the lead screw 558 rotates, causing the limiting post 1 556 and limiting post 2 557 to move to the left synchronously. At this time, limiting post 1 556 presses against limiting groove 1 554, and limiting post 2 557 presses against limiting groove 2 555. The limiting plate 1 551 moves downward, limiting the movement. Plate 2 552 moves forward. Since the shape and angle of limiting groove 1 554 and limiting groove 2 555 are the same, the moving distance of limiting plate 1 551 and limiting plate 2 552 is also the same. As limiting plate 1 551 and limiting plate 2 552 move, the corresponding connecting column 51 also moves synchronously. The tension spring 54 expands downward under force, and the vertically adjacent straightening wheel 2 53 slowly approaches straightening wheel 1 52 until straightening wheel 2 53 reaches the appropriate position. At this time, the adjustment work is completed. The microcontroller 7 controls motor 1 46 to run. The two upper motors 1 46 rotate in reverse, and the two lower motors 1 46 rotate in forward. The output shaft of motor 1 46 drives the straightening wheel 45 to rotate synchronously. The two sets of straightening wheels... As the electromagnetic wire moves to the right, the straightening wheel 45 presses against it. When the electromagnetic wire passes the left straightening wheel 1 52 and straightening wheel 2 53, straightening wheel 1 52 presses against the lower end of the outer surface of the electromagnetic wire, and straightening wheel 2 53 presses against the upper end of the outer surface of the electromagnetic wire. When the electromagnetic wire passes the right straightening wheel 1 52 and straightening wheel 2 53, straightening wheel 1 52 presses against the front end of the outer surface of the electromagnetic wire, and straightening wheel 2 53 presses against the rear end of the outer surface of the electromagnetic wire. At this time, the electromagnetic wire is straightened by the pressure of the two sets of straightening wheels 1 52 and straightening wheel 2 53. As the electromagnetic wire continues to move, the relatively rotating pressing wheel 45 presses against the electromagnetic wire, straightening the already straightened electromagnetic wire into a suitable shape, thus completing the straightening work of the electromagnetic wire.

[0028] It is worth noting that the microcontroller 7 disclosed in the above embodiments is an STM32F103RCT6 microcontroller, motor 1 46 is a 4632-R395 motor, and motor 2 47 is a 2BLD10-24GN-20S motor. The microcontroller 7 controls the operation of motor 1 46 and motor 2 47 using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
