[0019] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0020] like Figure 1 As shown, it is a schematic diagram of the structure of the shaping mold for the tail wire of the coil provided by the utility model. The shaping mold for the tail wire of the coil includes a base block 10, a ferrule cylinder 20 arranged on the base block 10, two wire clamping components 30 respectively arranged on the base block 10, two shaping components 40 respectively arranged on the base block 10 and located on one side of the ferrule cylinder 20, and two wire pressing components 50 respectively arranged on the base block 10. It can be imagined that the shaping mold for the tail wire of the coil also includes some other functional modules, such as a wire pulling module, a manipulator module, a power module, etc., which are technologies already known to those skilled in the art and will not be described one by one here.

[0021] Please also read Figures 2 to 5It should be noted that the shaping die of the coil tail wire shapes the tail wire of a coil 60. The tail wire structure state of the coil 60 and the state after shaping are the same, so the tail wire of the coil 60 is described together below.

[0022] A step 11 is provided at a position of the base block 10 near the ring cylinder 20, and the step 11 is used to cooperate with the wire crimping assembly 50 to perform wire crimping and shaping operations on the tail wire of the coil 60, so as to bend and cross the tail wire of the coil 60 and shape the protruding end of the tail wire of the coil 60 into a step shape. The specific operation process will be described below.

[0023] The base block 10 is provided with a plurality of through holes 12 , and the through holes 12 are used to pass through various components so that the various components can cooperate with each other to perform shaping operations on the coil 60 .

[0024] A slot 13 is formed on one end of the base block 10 away from the step 11 , and the two wire clamping assemblies 30 are correspondingly arranged in the slot 13 , so as to clamp the starting and tail wires on the coil 60 . The specific clamping situation will be described below.

[0025] The ferrule cylinder 20 is provided with an avoidance groove 21, which is used to cooperate with the wire crimping assembly 50 to perform wire crimping operation on the coil 60, so as to limit the coil 60 in a plane direction perpendicular to the coil 60. The specific cooperation will be described below.

[0026] The coil 60 is sleeved on the ring cylinder 20, and the starting and tail wires on the coil 60 are pulled onto the wire clamping assembly 30 through the wire pulling module. The wire clamping assembly 30 clamps the starting and tail wires on the coil 60, thereby fixing the coil 60 to prevent the coil 60 from rotating or displacing.

[0027] The clamping assembly 30 includes a fixing block 31 fixedly disposed on the slot 13 , a clamping rod 32 movably inserted into the slot 13 , and a first spring 33 sleeved on the clamping rod 32 .

[0028] The wire clamping rod 32 is movably located between the fixed block 31 and the slot 13. A wire clamping plate 34 is provided at one end of the wire clamping rod 31 away from the first spring 33. A right angle is formed between the wire clamping plate 34 and the wire clamping rod 32. In this way, when the wire clamping rod 32 is located in the slot 13 and reciprocates, the two wire clamping plates 34 and the two fixed blocks 31 can respectively clamp or release the starting and tail wires of the coil 60.

[0029] A first baffle 35 is provided at one end of the clamping rod 32 away from the clamping plate 34, one end of the first spring 33 abuts against the base block 10, and the other end abuts against the first baffle 35, so that the fixing block 31 and the clamping rod 32 can clamp the tail wire of the coil 60 under the action of the release of the elastic potential energy of the first spring 33, thereby tightening the tail wire of the coil 60. The external power module only needs to push the clamping rod 32, compress the first spring 33, and make the clamping plate 34 away from the fixing block 31, so that the tail wire of the coil 60 can be released.

[0030] The shaping assembly 40 includes two shaping blocks 41 movably penetrated on the base block 10 and located on one side of the ring cylinder 20, a limiting rod 42 fixedly penetrated on the base block 10, two second springs 43 respectively sleeved on the two shaping blocks 41, a locking rod 44 movably penetrated on the base block 10 and located on one side of the two shaping blocks 41, and a third spring 45 sleeved on the locking rod 44.

[0031] The shaping block 41 is provided with an arc-shaped first rack 411 on one side away from the ferrule cylinder 20. The first rack 411 can cooperate with the wire crimping assembly 50 to crimp the starting and tail wires of the coil 60. The specific crimping process will be described below.

[0032] The length direction of the shaping block 41 is perpendicular to the length direction of the limiting rod 42. The shaping block 41 is provided with a limiting groove 412 along its length direction. The limiting rod 42 passes through the limiting groove 412, so that the shaping block 41 can slide along the length direction of the limiting groove 412, and the maximum sliding distance is the length of the limiting groove 412.

[0033] A second baffle 46 is provided at one end of the shaping block 41 away from the ring cylinder 20, and one end of the second spring 43 abuts against the base block 10, and the other end abuts against the second baffle 46, so that the shaping block 41 can move toward the second spring 43 under the release of the elastic potential energy of the second spring 43, so that the end of the limiting groove 412 away from the second spring 43 abuts against the limiting rod 42.

[0034] A first slot 413 is respectively defined on one side of the two shaping blocks 41 facing the locking rod 44 , and a second slot 441 is respectively defined on the locking rod 44 at positions corresponding to the two first slots 413 . The first slot 413 and the second slot 441 correspond to each other.

[0035] A third baffle 47 is disposed at one end of the locking rod 44, one end of the third spring 45 abuts against the base block 10, and the other end abuts against the third baffle 47, so that the locking rod 41 can have a force to move toward the base block 10 under the release of the elastic potential energy of the third spring 45, and then when the locking rod 41 is pushed, the first clamping groove 413 can be clamped on the locking rod 41. In this way, the two shaping blocks 41 can be fixedly protruded from the base block 10, so as to cooperate with the wire crimping assembly 50 to perform wire crimping operation on the coil 60.

[0036] The shaping block 41 is in contact with the gap between the ring cylinder 20 , so before the coil 60 is sleeved on the ring cylinder 20 , the shaping block 41 can be passed through the second slot 441 , so that the shaping block 41 is hidden in the surface of the base block 10 , thereby facilitating the sleeve of the coil 60 on the ring cylinder 20 .

[0037] The starting and tail wires of the coil 60 clamped by the wire clamping assembly 30 are moved to the shaping block 41 through the wire pulling module and closely adhere to the outer contour of the shaping block 41 to wait for the wire pressing assembly 50 to perform the wire pressing and shaping operation.

[0038] The wire pressing assembly 50 includes two first pressing blocks 51 which are correspondingly arranged on the base block 10 and respectively located on both sides of the ring cylinder 20, two first clamping columns 52 which are respectively fixedly arranged on one side of the first pressing block 51, two second pressing blocks 53 which are correspondingly arranged on the base block 10 and respectively located on one side of the two wire clamping assemblies 30, and two second clamping columns 54 which are respectively fixedly arranged on one side of the second pressing block 53.

[0039] A first moving rod 511 is provided on one side of the first pressing block 51, and the first moving rod 511 is movably installed on the base block 10. A fourth spring 512 is sleeved on the first moving rod 511, and a fourth baffle 513 is provided on one end of the first moving rod 511 away from the first pressing block 51. One end of the fourth spring 512 abuts against the base block 41, and the other end abuts against the fourth baffle 513, so that the first pressing block 51 can perform a downward pressing action under the release of the elastic potential energy of the fourth spring 512, thereby performing a wire pressing operation on the coil.

[0040] A pressure strip 514 is provided at a position of the first pressure block 51 corresponding to the avoidance groove 21 . When the first pressure block 51 is pressed down, the pressure strip 514 can press the coil 60 corresponding to the avoidance groove 21 , thereby limiting the coil 60 and preventing the coil 60 from falling off.

[0041] A second rack 515 in a stepped shape is provided at the position of the first pressing block 51 corresponding to a part of the first rack 411, and a part of the first rack 411 and the second rack 515 are arranged alternately, so that when the first pressing block 51 is pressed down, the second rack 515 can press the starting and ending wires of the coil 60 at the first rack 411 to make the starting and ending wires of the coil 60 close to the outer contour of the shaping block 41, and the stepped second rack 515 matches the step 11 on the base block 10, so as to press the starting and ending wires of the coil 60 into a stepped shape.

[0042] The first pressing block 51 has a first slot 516 at a position corresponding to the first clamping column 52 , and the first clamping column 52 passes through the first slot 516 , thereby preventing the first moving rod 511 from driving the first pressing block 51 to rotate, thereby limiting the first pressing block 51 .

[0043] A second moving rod 531 is provided on one side of the second pressing block 53, and the second moving rod 531 is movably provided on the base block 10. A fifth spring 532 is sleeved on the second moving rod 531, and a fifth baffle 533 is provided on one end of the second moving rod 531 away from the second pressing block 53. One end of the fifth spring 532 abuts against the base block 41, and the other end abuts against the fifth baffle 533, so that the second pressing block 53 can perform a downward pressing action under the release of the elastic potential energy of the fifth spring 532, thereby performing a wire pressing operation on the coil.

[0044] An opening 534 is formed at the end of the second pressing block 53, and the opening 534 matches a tooth on the first rack 411. When the second pressing block 53 is pressed down, the opening 534 is clamped on the first rack 411, thereby pressing the starting and ending wires of the coil 60 so that the starting and ending wires of the coil 60 are tightly attached to the outer contour of the shaping block 41, thereby pressing it into an arc shape.

[0045] A second slot 535 is provided on the side wall of the second pressing block 53, and a third slot 536 is provided at one end of the second pressing block 53 away from the opening 534. The second and third slots 535 and 536 are matched with the second clamping column 54. When performing the wire pressing operation, the second clamping column 54 is clamped into the third slot 536 so that the opening 534 corresponds to the first rack 411. After the wire pressing operation is completed, the fifth baffle 533 is pushed to disengage the second clamping column 54 from the third slot 536, and the second moving rod 531 is rotated to drive the second pressing block 53 to rotate so that the second slot 535 corresponds to the second clamping column 54, so that the second pressing block 53 avoids the wire pulling path of the starting and tail wires of the coil 60 to prevent interference.

[0046] Compared with the prior art, the shaping die of the coil tail wire provided by the utility model clamps and tightens the tail wire of the coil 60 through the clamping assembly 30, waiting for the wire pulling module to move the tail wire of the coil 60 to one side of the shaping block 41, so that the tail wire of the coil 60 is closely attached to the outer contour of the shaping block 41, and cooperates with the wire pressing assembly 50 to perform wire pressing operation on the coil 60.
