The cross-section of the shaping portion 11 is semicircular; the width direction of the shaping portion 11 is the thickness direction of the shaping portion 11; the first shaping member 2 is arranged above the shaping portion 11, and the second shaping member 3 is arranged on the shaping portion 11 and is located below both sides of the first shaping member 2.
[0025] See also Figure 1 、 Figure 2 The coil 10 to be shaped is in a flat waist shape. When shaping the coil 10, both ends of the coil 10 need to be bent from the middle of the coil 10 toward the shaping portion 11, and the middle and both ends of the coil 10 need to be stretched outward to a predetermined distance.
[0026] Specifically, the coil 10 to be shaped is first placed on the shaping portion 11 of the base 1. Thereafter, the middle part of the coil 10 is pressed outward by the first shaping member 2, and then the two ends of the coil 10 are pressed down onto the arc surface of the shaping portion 11, so that the second shaping member 3 is located within the inner circle of the two ends of the coil 10. Thereafter, the second shaping member 3 is moved downward along the tangent direction of the shaping portion 11, so that the second shaping member 3 can push down the inner circle of the coil 10. When the second shaping member 3 moves to at least be tangent to the side surface of the shaping portion 11, the shaping of the two ends of the coil 10 is completed. At the same time, the first shaping member 2 is controlled to open the middle part of the coil 10 on both sides along the width direction of the shaping portion 11 to achieve the shaping of the middle part of the coil 10. The present application uses a first shaping member 2 provided on the top of the shaping portion 11 and a second shaping member 3 provided on both sides of the shaping portion 11 on the first shaping member 2 to respectively stretch the middle and both ends of the coil 10, and electrically heats the coil 10. After the coil 10 cools down, the shaping effect of the coil 10 can be achieved. The application has the characteristics of simple structure, convenient operation and low production cost.
[0027] In one or more embodiments, the first shaping member 2 includes a first limiter 21 and a second limiter 22 which are arranged at the top of the shaping portion 11 and can move in opposite directions along the width direction of the shaping portion 11; the second shaping member 3 includes a third limiter 31 and a fourth limiter 32 which are arranged on both sides of the shaping portion 11 and can move downward along the tangent of the shaping portion 11; the first limiter 21, the second limiter 22, the third limiter 31 and the fourth limiter 32 are contoured structures at the parts that contact the inner ring of the coil 10, and the contoured structures can adapt to the shape of the inner ring of the coil 10 after being shaped.
[0028] See also Figure 3 、 Figure 4 The first limiting member 21 and the second limiting member 22 are arranged at the top of the shaping portion 11 along the width direction of the shaping portion 11, and the first limiting member 21 and the second limiting member 22 can move toward or away from each other; the third limiting member 31 and the fourth limiting member 32 are respectively arranged on both sides of the shaping portion 11 on the first shaping member 2, and the third limiting member 31 and the fourth limiting member 32 can both move along a certain tangent line of the shaping portion 11 to move obliquely downward or obliquely upward.
[0029] See also Figure 3 、 Figure 4The ends of the first limiter 21, the second limiter 22, the third limiter 31 and the fourth limiter 32 that contact the inner ring of the coil 10 are contoured structures, and the contoured structures can adapt to the shape of the inner ring of the coil 10 after forming; wherein, the contoured structure size of the ends of the first limiter 21 and the second limiter 22 is smaller than the contoured structure size of the ends of the third limiter 31 and the fourth limiter 32; in other possible embodiments, the contoured structure size of the ends of the first limiter 21 and the second limiter 22 is larger than the contoured structure size of the ends of the third limiter 31 and the fourth limiter 32. There is no specific limitation and it needs to be determined according to the type of shaping of the coil 10.
[0030] See also Figure 3 、 Figure 4 When shaping the coil 10, first place the planar coil 10 on the top of the shaping part 11 so that the first limiter 21 and the second limiter 22 are located inside the coil 10 of the shaping part 11. Then, control the first limiter 21 and the second limiter 22 to move in opposite directions to press against the middle of the planar coil 10. Then, press the two ends of the planar coil 10 down on the arc surface of the shaping part 11 so that the third limiter 31 and the fourth limiter 32 are respectively located inside the two ends of the bent coil 10. Control the third limiter 31 and the fourth limiter 32 to move synchronously and tilt downward to press against the inner circles at both ends of the coil 10. Then, power on the coil 10 for heating. After the coil 10 cools down, the shaping of the coil 10 is achieved. It has the characteristics of simple structure, convenient operation, and practicality.
[0031] In one or more embodiments, the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32 are respectively driven by four groups of control structures 4 configured on the shaping part 11, and the control structure 4 includes a fixing plate 41 and an adjustment bolt 42 threadedly connected to the fixing plate 41.
[0032] See also Figure 3 、 Figure 4 、 Figure 5 The control structure 4 has four groups, which respectively control the first limit member 21 and the second limit member 22 to move toward or away from each other at the top of the shaping part 11, and control the third limit member 31 and the fourth limit member 32 to move obliquely upward or obliquely downward along the tangent direction of the side of the shaping part 11; the control structure 4 is a fixed plate 41 fixedly installed on the shaping part 11 and an adjusting bolt 42 threaded on the fixed plate 41, and the four groups of adjusting bolts 42 are rotatably installed on the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32 at the end away from the fixed plate 41.
[0033] Specifically, when the inner turn of the coil 10 is shaped, the two sets of adjusting bolts 42 at the top of the shaping part 11 are controlled to rotate on the two sets of fixing blocks respectively, so that the first limit member 21 and the second limit member 22 move in opposite directions, and the two sets of adjusting bolts 42 on both sides of the shaping part 11 are controlled to rotate on the two sets of fixing blocks respectively, so that the third limit member 31 and the fourth limit member 32 move obliquely downward along the tangential direction of the side of the shaping part 11. Through this arrangement, the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32 can be respectively pressed against the inner turn of the coil 10, thereby achieving fixation of the coil 10 before shaping.
[0034] In other possible embodiments, the control structure 4 can also be four groups of driving cylinders arranged on the shaping part 11. The four groups of driving cylinders can control the first limit member 21 and the second limit member 22 to move toward or away from each other, and control the third limit member 31 and the fourth limit member 32 to move obliquely upward or obliquely downward along the tangential direction of the side of the shaping part 11.
[0035] In one or more embodiments, the concave surface of the shaping portion 11 is provided with a support structure 5 to maintain the support strength of the shaping portion 11. Figure 5 The cross-section of the shaping portion 11 is semicircular, and the shaping portion 11 is concave on the side facing the base 12. The concave surface of the shaping portion 11 and the supporting structure 5 installed on the base 12 can be a plate or other possible fillers; through this arrangement, the deformation of the shaping portion 11 due to external force can be reduced, thereby extending the service life of the shaping tooling of the present application.
[0036] In one or more embodiments, a through limiting groove 6 is provided on the shaping portion 11 , and both the first shaping component 2 and the second shaping component 3 move on the shaping portion 11 along the limiting groove 6 .
[0037] See also Figure 4 , there are four groups of limit slots 6, and the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32 correspond to one group of limit slots 6 respectively; the bottom ends of the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32 all extend out of the corresponding limit slots 6, thereby realizing the restriction of their respective moving directions and positions, ensuring the stability of the movement of the first limit member 21, the second limit member 22, the third limit member 31 and the fourth limit member 32, and then ensuring the shaping effect of the coil 10 of this application.
[0038] In one or more embodiments, the base 1 is made of hard plastic. This configuration can provide insulation when the coil 10 is energized, while also ensuring compression resistance using its own strength, thereby extending the service life of the base 1.
