As shown in fig. 1 to 8, the coil shaping device 10 provided in the embodiment of the present utility model can be used for shaping the coil 20 to be shaped into an arc-shaped coil. For example, the straight coil is shaped into a racetrack coil with an arc shape, so that the arc coil shaped by the coil shaping device 10 of the embodiment not only has the excellent product performance of the racetrack coil, but also is installed in an arc groove of the product, and the groove filling rate of the coil can be increased without increasing the size of the coil.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.

As shown in fig. 2, 4 and 5, the coil shaping device 10 provided in the embodiment of the utility model includes a winding former assembly 100 and a shaping former 200, wherein the winding former assembly 100 is used for winding the coil 20 to be shaped, for example, before shaping, copper wires are used to wind the coil 20 to be shaped, which meets the set number of turns of specification, on the winding former assembly 100. The shaping die 200 can be connected to the winding die assembly 100, the shaping die 200 being provided with a shaping arc 300, the shaping arc 300 being used to shape the contour of the coil 20 to be shaped into an arc, for example the shaping arc 300 shaping the contour of a straight coil into an arc. When the shaping die 200 is in the working state, the shaping die 200 moves in a direction approaching or separating from the coil 20 to be shaped relative to the winding die assembly 100 under the action of an external force, so that the shaping cambered surface 300 presses the coil 20 to be shaped or the shaping cambered surface 300 is separated from the coil 20 to be shaped.

It can be appreciated that the coil shaping apparatus 10 of the present embodiment simplifies the structure of the coil shaping apparatus 10 by providing the winding former assembly 100 and the shaping former 200 provided with the shaping cambered surface 300, and the shaping former 200 can shape the contour of the coil 20 to be shaped wound on the winding former assembly 100, which is advantageous in simplifying the manufacturing process when manufacturing the coil shaping apparatus 10. The shaping die 200 is connected to the winding die assembly 100, and can move relative to the winding die assembly 100 along a direction close to the coil 20 to be shaped under the action of external force when in a working state, so as to utilize the shaping cambered surface 300 to extrude and shape the coil 20 to be shaped, thereby modifying the contour of the coil 20 to be shaped, and finally integrally shaping the coil 20 to be shaped into an arc-shaped coil, thereby simplifying the coil shaping mode. Meanwhile, the shaping die 200 can also move relative to the winding die assembly 100 along the direction away from the coil 20 to be shaped under the action of external force, so that the shaping cambered surface 300 can be far away from the coil 20 to be shaped, and the coil 20 to be shaped can be taken out or properly adjusted, and the shaped arc-shaped coil can also be taken out.

Moreover, the whole arc length of the arc-shaped coil obtained by shaping by using the coil shaping device 10 is the same as the length of the coil 20 to be shaped, but the straight line length formed by connecting the two ends of the arc-shaped coil is shorter than that of the coil 20 to be shaped, the coil 20 to be shaped is arranged in an arc-shaped groove of a product, and the gap between the arc-shaped coil and the arc-shaped groove is smaller, so that the groove filling rate of the coil can be increased without increasing the size of the coil, and the performance of the product is further improved.

In addition, when the coil shaping device 10 is used, the user only needs to apply an external force to the shaping die 200 to cause the shaping die 200 to move towards the coil 20 to be shaped, so that the shaping cambered surface 300 presses the coil 20 to be shaped until the user also has difficulty in causing the shaping die 200 to continue to move towards the coil 20 to be shaped when applying the external force, the operation of the user is convenient, and a complex shaping machine is not needed.

As shown in fig. 3 and 4, as an embodiment, the winding mold assembly 100 includes a pin 110 and a winding module 120 for winding the coil 20 to be shaped, and the pin 110 is detachably disposed on the winding module 120. In the first direction, at least part of the bolt 110 protrudes out of the winding module 120, so that a gap is formed between the winding module 120 and part of the coil 20 to be shaped, and when the coil 20 to be shaped is shaped and bound, the gap can be utilized and the binding band can pass through the gap, so that the binding of the arc-shaped coil is facilitated. Since the pins 110 protrude from the winding module 120 along the first direction, the pins 110 are easily removed from the winding module 120. The first direction is perpendicular to the moving direction of the sizing die 200, and can be understood as a vertical direction when the winding die set 120 is horizontally placed on the supporting surface and the sizing die 200 is moved in the horizontal direction. When the sizing die 200 is in the working state, the sizing die 200 is slidably connected to the winding die set 120, so that the sizing die 200 can move relative to the winding die set 120. Since the pin 110 protrudes out of the winding module 120, the avoiding groove 400 for avoiding the pin 110 is provided in the sizing die 200, so that the sizing die 200 can slide on the surface of the winding module 120 conveniently.

As shown in fig. 3 and 4, as an embodiment, the latch 110 is detachably connected to opposite sides of the winding module 120 in the first direction. The two pins 110 extend upward and downward from two opposite sides of the winding module 120 along the first direction, so that in the first direction, gaps can be formed between two opposite sides of the winding module 120 and the wound coil 20 to be shaped, and the shaped arc-shaped coil can be conveniently bound at multiple positions. Generally, before winding the coil 20 to be shaped around the winding former assembly 100, a protective film is laid on the pin 110 to prevent the pin 110 from directly contacting the coil 20 to be shaped, and to prevent the pin 110 from damaging the coil 20 to be shaped.

As shown in fig. 3, as an embodiment, the winding module 120 is provided with a groove 130, and the plug 110 is detachably mounted in the groove 130, so as to facilitate mounting of the plug 110. The length of the plug 110 is longer than the length of the winding module 120 in the moving direction of the sizing die 200, so that when the plug 110 is removed, the plug 110 is conveniently knocked out of the groove 130 using a tool, thereby facilitating the removal of the plug 110.

As shown in fig. 3, as an embodiment, the winding module 120 is provided with a first guiding and sliding part 140, the first guiding and sliding part 140 is located at two opposite sides of the latch 110, the sizing die 200 is provided with a second guiding and sliding part 500, the second guiding and sliding part 500 is located at two opposite sides of the avoiding groove 400, and the sizing die 200 is slidably connected with a part of the first guiding and sliding part 140 through the second guiding and sliding part 500 so as to be slidably matched with the winding module 120. In this embodiment, the arrangement of the first guiding and sliding portion 140 and the second guiding and sliding portion 500 not only realizes the sliding fit between the sizing die 200 and the winding die set 120, but also improves the stability of the movement of the sizing die 200 in the working state relative to the winding die set 120.

As shown in fig. 3, as an embodiment, one of the first guide sliding portion 140 and the second guide sliding portion 500 is a guide rail, and the other is a chute. For example, the first guiding and sliding portion 140 is a linear guide, and the second guiding and sliding portion 500 is a sliding slot, so that the first guiding and sliding portion 140 can guide the second guiding and sliding portion 500 to slide linearly, thereby guiding the sizing die 200 to move linearly relative to the winding die set 120.

As shown in fig. 3 and 4, as an embodiment, at least a portion of the first sliding guide portion 140 is protruding on the winding module 120 in the first direction, a space is formed between the first sliding guide portion 140 and the pin 110, and along the moving direction of the sizing die 200, a local portion of the first sliding guide portion 140 between two ends is attached to a portion of the coil 20 to be shaped, so that a gap through which the binding wire passes is formed between the pin 110, the first sliding guide portion 140 and the coil 20 to be shaped. Moreover, the first sliding guide portion 140 and the pin 110 simultaneously support the coil 20 to be shaped, so that the balance stability of the coil 20 to be shaped around the winding module 120 can be improved.

As shown in fig. 5, 6 and 7, as an embodiment, the winding module 120 includes a first winding die 121 and a second winding die 122, the first winding die 121 and the second winding die 122 are arranged side by side along a first horizontal direction, and in an embodiment in which the winding module 120 is horizontally placed on a supporting surface, the first horizontal direction may be understood as a direction in which the sizing die 200 moves back and forth along the horizontal direction. The first winding former 121 and the second winding former 122 are in plug-in fit, the first winding former 121 and the second winding former 122 are designed to be in a split detachable mode, after shaping is finished, the shaped arc-shaped coil is fixed by using a binding belt, the first winding former 121 is detached from the second winding former 122, or the second winding former 122 is detached from the first winding former 121, and then the shaped arc-shaped coil is removed, so that the difficulty in taking out the coil after shaping is finished is reduced. In the first horizontal direction, the first winding mold 121 is provided with a slot 123, the slot 123 is communicated with a part of the groove 130 formed on the upper end surface of the first winding mold 121, the second winding mold 122 is provided with a plugboard 124, and the plugboard 124 is plugged into the slot 123 to realize plug-in fit between the first winding mold 121 and the second winding mold 122.

The width of the first winding former 121 is greater than the width of the second winding former 122 in a second horizontal direction, which is perpendicular to the first horizontal direction, and which may be understood as a left-right direction in an embodiment in which the winding module 120 is horizontally placed on the supporting surface. The width of the junction of the first and second bobbins 121 and 122 in the second horizontal direction extends from the second bobbin 122 toward the first bobbin 121 in a gradually increasing width direction, and forms a winding station 125 for winding the coil 20 to be shaped. It will be appreciated that the width of the winding station 125 increases gradually from the second winding die 122 toward the first winding die 121, so that the length of the coil 20 to be shaped in the second horizontal direction also increases gradually from the second winding die 122 toward the first winding die 121, thereby facilitating the profile of the coil 20 to be shaped to be gradually extruded by the shaping die 200 into an arc shape.

As shown in fig. 4, 5 and 6, as an embodiment, the shaping die 200 is slidably connected to the second winding die 122, and the center of the shaping arc 300 is located at a side of the shaping arc 300 away from the coil 20 to be shaped. It can be understood that the center of the shaping arc 300 is located at one side of the shaping arc 300 facing away from the coil 20 to be shaped, and the shaping die 200 pushes the shaping arc 300 to move away from the center of the shaping arc to press a side of the coil 20 to be shaped facing the coil 20 to be shaped. The end of the first winding mold 121 far away from the second winding mold 122 is used for abutting against a first supporting surface (not labeled), for example, an end surface of the first winding mold 121 far away from the second winding mold 122 abuts against a wall surface, so that the first winding mold 121 and the second winding mold 122 are kept connected with each other in the moving process of the sizing mold 200, and at least part of the plug 110 is prevented from being separated from the first winding mold 121 and/or the second winding mold 122 along the moving direction of the sizing mold 200, thereby effectively avoiding the phenomenon that the plug 110 is separated from the winding mold 120 in the shaping process of the coil 20 to be shaped.

As shown in fig. 4, 6 and 7, as one embodiment, the first winding die 121 includes a first body portion 1211, a second body portion 1212, and a first support portion 1213, the first body portion 1211 and the second body portion 1212 being connected to each other in a first horizontal direction, and the first body portion 1211 having a width greater than that of the second body portion 1212 in a second horizontal direction. The first body 1211 is connected to the first support 1213, and the first support 1213 is at least used for placing the first body 1211 and the second body 1212 on a second support surface, such as a table top, and the second body 1212 and the second winding die 122 are in plug-in fit, and form a winding station 125 with the second winding die 122, and the coil 20 to be shaped is wound on the winding station 125. The width of the second body portion 1212 in the second horizontal direction extends from the junction of the second body portion 1212 and the second wire-winding die 122 to the junction of the second body portion 1212 and the first body portion 1211 in a gradually increasing trend. In an embodiment of the present utility model, the formation of the winding station 125 is embodied and provides a location for the coil 20 to be shaped to be wound therearound.

As shown in fig. 5, 6 and 7, as an embodiment, the second winding die 122 includes a main body 1221 and a second supporting portion 1222, the second main body 1212 and the main body 1221 are in plug-fit, the sizing die 200 is slidably connected to the main body 1221, the main body 1221 is connected to the second supporting portion 1222, the second supporting portion 1222 is at least used for placing the main body 1221 on the second supporting surface, and at least a part of the second main body 1212 and a part of the main body 1221 form the winding station 125. In the embodiment of the present utility model, the second supporting portion 1222 can form a space between the main body portion 1221 and the second supporting surface for sliding the partial shaping die 200 located on the lower end surface of the main body portion 1221, so that the shaping die 200 can simultaneously squeeze and shape the coil 20 to be shaped wound on the upper surface and the lower surface of the winding station 125, and the shaping effect is improved.

As shown in fig. 4, 6 and 7, in one embodiment, in the second horizontal direction, the first supporting portions 1213 are disposed on opposite sides of the second body portion 1212, the second supporting portions 1222 are disposed on opposite sides of the main body portion 1221, and a limiting space for limiting the winding position of the coil 20 to be shaped is formed between the first supporting portions 1213 and the second supporting portions 1222. In the first horizontal direction, the first support portion 1213 and the second support portion 1222 located on the same side of the coil 20 to be shaped are offset, and at least a portion of the second body portion 1212 and a portion of the main body portion 1221 located between the first support portion 1213 and the second support portion 1222 form the winding station 125. In the present utility model, such arrangement of the first support portion 1213 and the second support portion 1222 not only provides a position for restricting the winding of the coil 20 to be shaped, but also effectively prevents the coil 20 to be shaped from being entirely shifted to both front and rear sides during winding or shaping, and reduces the probability of the coil 20 to be shaped from being shifted.

As shown in fig. 5 and 8, as an embodiment, the shaping die 200 includes a first shaping portion 210, a second shaping portion 220, and a connection base 230, where the first shaping portion 210 and the second shaping portion 220 are disposed opposite to each other at a distance in the first direction, and the connection base 230 is connected between the first shaping portion 210 and the second shaping portion 220. The connection seat 230 has a function of connecting the first shaping portion 210 and the second shaping portion 220, and improves the overall structural stability of the shaping die 200. The body portion 1221 is interposed between the first shaping portion 210 and the second shaping portion 220, and both the first shaping portion 210 and the second shaping portion 220 are slidably connected to the body portion 1221. That is, when the sizing die 200 is in the working state, the main body 1221 is located in the space surrounded by the first shaping portion 210, the connecting base 230, and the second shaping portion 220. Along the moving direction of the shaping die 200, the end of the first shaping portion 210 facing the winding die assembly 100 and the end of the second shaping portion 220 facing the winding die assembly 100 are both provided with shaping cambered surfaces 300, so that the first shaping portion 210 and the second shaping portion 220 simultaneously extrude and shape the coil 20 to be shaped wound on the upper surface and the lower surface of the winding station 125, and the shaping effect is improved. The connecting seat 230 is used for driving the first shaping portion 210 and the second shaping portion 220 to move along a direction approaching the coil 20 to be shaped under the action of an external force, so as to drive the shaping cambered surface 300 to move.
