[0023] When the core 3 is pressed, first, the second driving device 45 is started to move the guide cylinder 44 downward to approach the outer side surface of the core 3, until the guide cylinder 44 contacts with the elastic sealing ring on the side wall of the core 3, at this time, the inner wall of the guide cylinder 44 can play a guiding role for the core 3 when the lower pressing cylinder 42 presses the core 3 downward, to prevent the core 3 from tilting and deviating when moving downward, then the first driving device 43 is started, the lower pressing cylinder 42 moves downward to approach the upper surface of the core 3, and after contacting with the upper surface of the core 3, the core 3 is pressed downward into the inside of the feeding press head 31.

[0024] Please refer to Figures 3-5The wire dialing mechanism 5 comprises a wire dialing frame 51 and two wire guide plates 52 mounted on the wire dialing frame 51, the wire dialing frame 51 is symmetrically arranged on the first control plate 411 away from the side of the accommodation slot 421, the first control plate 411 is slidably provided with a first push plate 53 at the bottom, and the end of the wire dialing frame 51 away from the pressing cylinder 42 is slidably mounted on the first push plate 53, a third driving device 54 is mounted below the first control plate 411, the output end of the third driving device 54 is connected with the first push plate 53, and the first push plate 53 can be reciprocatingly moved by the third driving device 54, close to or away from the pressing cylinder 42. The wire guide plate 52 is slidably mounted at the lower end of the wire dialing frame 51, and the side away from each other of the two wire guide plates 52 is connected with a spring 55, the other end of the spring 55 is connected with the wire dialing frame 51, and the faces close to each other of the two wire guide plates 52 are in contact at the beginning, the two sides of the wire guide plate 52 are symmetrically provided with inclined surfaces, and the end faces of the ends of the inclined surfaces away from each other are vertically arranged along the length direction of the pressing cylinder 42, when the two wire guide plates 52 are in contact, the inclined surfaces of the two wire guide plates 52 can be combined into a sharp cone structure. The first control plate 411 is provided with a first guide slot 412 at the bottom along the moving direction of the first push plate 53, and the top end of the wire dialing frame 51 is slidably mounted in the first guide slot 412, and the first guide slot 412 is arranged to ensure that the faces close to each other of the two wire guide plates 52 are always in contact with the outer side surface of the pressing cylinder 42 and the outer side surface of the core 3 when the wire guide plates 52 move on the pressing cylinder 42.

[0025] Before the pressing mechanism 4 works, the lower pressing cylinder 42 is first moved downward to a certain height, leaving a gap between the lower pressing cylinder 42 and the core 3 for placing the wires 32, at this time the length of the wire plate 52 in the vertical direction is greater than the gap between the lower pressing cylinder 42 and the core 3, then the third driving device 54 drives the first push plate 53 to push the wire plate 52 close to the lower pressing cylinder 42, because the diameter of the bottom surface of the lower pressing cylinder 42 is the same as the diameter of the upper surface of the core 3, the wire plate 52 is in contact with the outer side of the lower pressing cylinder 42 and the core 3 at the same time, at this time the wires 32 on the core 3 are pushed to one side of the wire plate 52 under the action of the sharp cone structure composed of the inclined surface of the wire plate 52, then under the action of the first guide groove 412, the two wire plates 52 move away from each other while moving, and the side of the two wire plates 52 close to each other is in contact with the outer side of the lower pressing cylinder 42 and the core 3 at the same time, the wires 32 are pushed to approach the accommodation slot 421, when the wire plate 52 continues to move to the side close to the accommodation slot 421, the two wire plates 52 are in contact again under the action of the first guide groove 412, and at this time the wires 32 are clamped between the two wire plates 52, because the spring 55 is connected on the wire plate 52, it prevents clamping the wires 32 while preventing damaging the surface of the wires 32, the first push plate 53 continues to move, at this time the wires 32 are gradually straightened, and at this time the accommodation slot 421 is just located above the wires 32. Then the pressing mechanism 4 works, the lower pressing cylinder 42 and the guide cylinder 44 move downward and make the wires 32 enter the accommodation slot 421, ensuring that the lower pressing cylinder 42 moves downward and presses the core 3 downward into the inside of the pressing head 31.

[0026] Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7The wire pushing mechanism 5 further comprises a lead wire structure installed on the machining table 2, the lead wire structure is arranged below the installation groove 21, and the lead wire structure comprises a lead wire plate 7 installed on the bottom surface of the machining table 2. One side of the lead wire plate 7 is slidably provided with a second push plate 71, and the machining table 2 is provided with a fourth driving device 72. The output end of the fourth driving device 72 is connected with the second push plate 71, and the fourth driving device 72 can drive the second push plate 71 to move up and down, to move close to or away from the installation groove 21. Two limiting columns 73 are slidably connected to the second push plate 71, and the limiting columns 73 are symmetrically arranged on the two sides of the installation groove 21. The lead wire plate 7 is provided with second guide grooves 74 in the moving direction of the second push plate 71, and the two second guide grooves 74 gradually approach the direction close to the installation groove 21. The limiting column 73 is provided with a guide column 731 reciprocally sliding in the second guide groove 74. The end of the limiting column 73 close to the installation groove 21 is provided with an arc-shaped plate 732, and the arc-shaped plates 732 on the two limiting columns 73 are cross arranged. In the initial state, the arc-shaped plate 732 is below the upper surface of the installation groove 21, and at this time, the two arc-shaped plates 732 do not contact. When the second push plate 71 moves upward, the limiting columns 73 approach each other under the action of the second guide grooves 74, and simultaneously drive the arc-shaped plates 732 to move synchronously until the two ends of the arc-shaped plates 732 contact. At this time, the inner arc surfaces of the two arc-shaped plates 732 and the two end contact parts jointly form a closed space, and then the arc-shaped plates 732 continue to approach and gradually reduce the closed space.

[0027] After the core 3 is pressed into the inside of the pressing head 31, the pressing mechanism 4 moves upward. At this time, the lead wire 32 is still clamped by the lead wire plate 52. The fourth driving device 72 is started and drives the limiting column 73 to move upward through the second push plate 71. The limiting column 73 approaches and makes the two ends of the arc-shaped plates 732 contact to form a closed space under the cooperation of the second guide grooves 74 and the guide column 731. At this time, the arc-shaped plates 732 are below the lead wire 32. Then the lead wire plate 52 moves reversely and releases the lead wire 32. At this time, the lead wire 32 falls and is placed on the upper surface of the pressing head 31 until the lead wire plate 52 moves to the initial position. The machining table 2 rotates to the next station. Then the arc-shaped plates 732 continue to move upward to the upper surface of the pressing head 31 and continue to approach each other, so that the closed space gradually becomes smaller and clamps the lead wire 32 in the closed space. Until the arc-shaped plates 732 move upward to the state that the lead wire 32 remains vertical and stop moving. At this time, the arc-shaped plates 732 just move below the joint of the lead wire 32. The closed space jointly formed by the inner arc surfaces of the arc-shaped plates 732 and the two end contact parts has a cross section smaller than that of the joint of the lead wire 32. The cross section of the joint of the lead wire 32 is larger than that of the lead wire 32, so that the joint of the lead wire 32 can be limited, and the lead wire 32 is prevented from falling from between the two arc-shaped plates 732.

[0028] Please refer to Figure 2 and Figures 7-10The fixing mechanism 6 comprises a second control device 61 arranged on one side of the shell 1, and the second control device 61 is arranged at a position apart from the first control device 41 by one station. A second control plate 611 is arranged above the second control device 61. The second control plate 611 can be controlled to rotate around an axis and move up and down by the second control device 61. When the lead 32 is straightened to a vertical state by the lead structure, the core 3 is rotated to the pressing mechanism 4, and the second control plate 611 can be controlled to move to the position directly above the core 3 by the second control device 61. A lifting column 612 is arranged at the bottom of the second control plate 611. Two clamping blocks 613 are rotatably arranged at the bottom of the lifting column 612. The two clamping blocks 613 are symmetrically arranged. When the side of the clamping block 613 close to each other is kept in a vertical state, the side away from each other is a slope. The side of the clamping block 613 close to each other is made of a flexible material. The flexible material can be selected from rubber, silica gel, sponge, and flexible fiber, which have certain elasticity and deformation ability. A torsional spring 614 is connected to the rotating shaft of the clamping block 613. The other end of the torsional spring 614 is connected to the bottom of the lifting column 612. Since the rotating shaft of the clamping block 613 is above it, the torsional spring 614 makes the lower ends of the clamping blocks 613 away from each other under the action of no external force. A lifting plate 62 is slidably arranged on the lifting column 612. A fifth driving device 63 is arranged above the second control plate 611. The output end of the fifth driving device 63 is connected to the upper surface of the lifting plate 62. The lifting plate 62 can be driven to move up and down along the lifting column 612 by the fifth driving device 63. A rotating drum 64 is slidably sleeved on the outside of the lifting column 612. A first gear 641 is arranged on the rotating drum 64. A second gear 642 is rotatably arranged at the bottom of the lifting plate 62 and engaged with the first gear 641. A motor 65 is arranged above the lifting plate 62. The output end of the motor 65 is connected to the second gear 642. The second gear 642 and the first gear 641 can be driven to rotate synchronously by the motor 65, thereby driving the rotating drum 64 to rotate around an axis along the outer wall of the lifting column 612.

[0029] When the core 3 rotates to the position of the fixing mechanism 6, the second control plate 611 moves to the position of placing the compression ring 33, then the rotating drum 64 moves downward and pushes the clamping blocks 613 downward, so that the two clamping blocks 613 rotate towards each other, the torsional springs 614 are twisted under the force, and finally the clamping blocks 613 are pushed into the rotating drum 64, at this time, the two clamping blocks 613 are closest to each other, the side close to each other is parallel and vertical, after the compression ring 33 is limited and adsorbed to the bottom of the rotating drum 64, the rotating drum 64 moves upward, the clamping blocks 613 are reset under the action of the torsional springs 614, and the inclined surface of the side far away from each other can just contact the compression ring 33 at this time, for auxiliary support of the compression ring 33. Then the second control device 61 controls the second control plate 611 to move above the wire 32 end joint, adjusts the height of the second control plate 611 so that the two clamping blocks 613 are just located on both sides of the wire 32 end joint, at this time, the clamping blocks 613 are pushed downward again by the rotating drum 64 moving downward driven by the lifting plate 62, and the clamping blocks 613 rotate towards each other while clamping the wire 32 end joint, the side close to each other of the clamping blocks 613 is made of flexible material to avoid damaging the joint.
