[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention rolls the Great Wall buckle on copper wire rods of different thicknesses, by adjusting the rotation of the adjusting screw rod driven by the motor, the adjusting threaded ring moves along the axis direction of the adjusting screw rod, thereby changing the spacing size between the two adjusting threaded rings, and thus changing the end widths of the lower rolling punch and the upper rolling punch, so that the spacing size between the lower rolling punch and the upper rolling punch after they approach each other is the thickness of the copper wire rod, thereby rolling copper wire rods of different thicknesses, and thus eliminating the need for multiple devices to roll copper wire rods of different thicknesses, achieving a reduction in production costs; 2. The present invention compresses the formed part of the copper wire rod by using the first pressing block and the second pressing block that are aligned up and down to ensure that the formed part of the copper wire rod will not be pulled by the punching force during the forming process, thereby avoiding deformation of the formed part of the copper wire rod; 3. The present invention starts the moving motor inside the first connecting plate clockwise, while the moving motor inside the second connecting plate rotates counterclockwise, so that the upper rotating plate rotates clockwise, and the lower rotating plate rotates counterclockwise, so that the rotating plate pushes the moving connecting rod to slide reciprocally inside the moving chute. When the moving connecting rod slides reciprocally, it drives the moving plate to perform reciprocating motion. The two moving plates approach each other and contact the rolled Great Wall buckle. At this time, the moving plate moves along the copper wire rod transportation direction, causing the copper wire rod to move a distance. After the copper wire rod moves, the two moving plates move away from each other and separate from the Great Wall buckle. The moving plate moves reciprocally, and during the continuous movement of the moving plate, it pushes the rolled part of the copper wire rod to move, thereby realizing the intermittent movement of the copper wire rod, and the length of each movement of the copper wire rod is the same, thereby avoiding defects or dimensional errors in the rolled Great Wall buckle due to inconsistent movement distances of the copper wire rod; 4. The present invention installs two rows of symmetrically distributed guiding wheels inside the guiding plate, and uses the guiding wheels with guiding grooves on their outer surfaces to guide and transport the copper wire rod to be rolled, thereby avoiding skewing or position deviation of the copper wire rod during the transportation process, and thus ensuring that there are no dimensional errors in the rolled Great Wall buckle; 5. The present invention uses the side limiting baffle to guide and transport the rolled Great Wall buckle, and cooperates with the wire guiding and transporting frame to ensure that the copper wire rod will not deviate or skew during rolling.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Such as Figure 1 and Figure 2As shown in the figure, an adjustable rolling forming device for copper wire Great Wall cards includes a fixed seat 1 and a top cover 2. The top cover 2 is located above the fixed seat 1, and four symmetrically distributed support frames 3 are fixed between the top cover 2 and the fixed seat 1. Reinforcement slots 8 are provided on the outer sides of both ends of the support frames 3. Two reinforcement enclosing plates 7 are provided on the outer sides of the four support frames 3. Both of the two reinforcement enclosing plates 7 are clamped inside the reinforcement slots 8. The four support frames 3 are used to support the fixed seat 1 and the top cover 2, and the four support frames 3 are reinforced from the outside by the reinforcement enclosing plates 7 to prevent the four support frames 3 from falling off between the fixed seat 1 and the top cover 2.

[0020] As Figures 2 to 4 shown in the figure, a rolling die 5 is installed between the fixed seat 1 and the top cover 2. The rolling die 5 includes an upper hydraulic rod 506, a lower hydraulic rod 507, a first pressing hydraulic rod 510 and a second pressing hydraulic rod 511. The upper hydraulic rod 506 and the first pressing hydraulic rod 510 are fixed inside the fixed seat 1, and an upper moving plate 509 and the second pressing hydraulic rod 511 are respectively fixed at the bottom ends. The lower hydraulic rod 507 and the second pressing hydraulic rod 511 are respectively fixed inside the lower hydraulic rod 507, and a lower moving plate 508 and a second pressing plate 513 are fixed at the top ends. Rolling punches 503 are fixed on the upper surface of the lower moving plate 508 and the bottom surface of the upper moving plate 509. First pressing blocks 501 and second pressing blocks 502 are fixed on the bottom surface of the first pressing plate 512 and the upper surface of the second pressing plate 513. The first pressing blocks 501 and the second pressing blocks 502 are aligned vertically. The first pressing blocks 501, the second pressing blocks 502 and the rolling punches 503 penetrate through the fixed seat 1 and the top cover 2. A lower rolling limit block 504 is also fixed on the upper surface of the lower moving plate 508 and penetrates through the fixed seat 1. An upper rolling limit block 505 is also fixed on the bottom surface of the upper moving plate 509 and penetrates through the top cover 2. The formed part of the copper wire is pressed by the vertically aligned first pressing blocks 501 and second pressing blocks 502 to ensure that the formed part of the copper wire will not be pulled by the punching force during rolling during the forming process of the copper wire, thereby avoiding deformation of the formed part of the copper wire.

[0021] The rolling punch 503 includes a lower rolling punch 5031 and an upper rolling punch 5032. The lower rolling punch 5031 penetrates through the fixed seat 1 and is fixed to the upper moving plate 509. The first pressing plate 512 penetrates through the top cover 2 and is fixed to the lower moving plate 508. The lower rolling punch 5031 is vertically aligned with the upper rolling limit block 505, and the lower rolling punch 5031 and the lower rolling limit block 504 are spaced apart. The upper rolling punch 5032 is vertically aligned with the upper rolling limit block 505, and the upper rolling punch 5032 and the upper rolling limit block 505 are spaced apart. The copper wire is punched up and down by the vertically aligned lower rolling punch 5031 and the upper rolling limit block 505 and the upper rolling punch 5032 and the lower rolling limit block 504, so that the copper wire is bent and formed into a Great Wall buckle.

[0022] The lower rolling punch 5031 and the upper rolling punch 5032 both include a rolling connection block 50301. Inside one end of the rolling connection block 50301, a regulation motor 50302 is fixed. At the output shaft end of the regulation motor 50302, a regulation lead screw 50308 is fixed. The other end of the regulation lead screw 50308 penetrates through the rolling connection block 50301, and a regulation thread ring 50309 is sleeved outside the end. The regulation thread ring 50309 is in threaded transmission with the regulation lead screw 50308. Two symmetrically distributed regulation inclined rods 50311 are fixed on the outside of the regulation thread ring 50309.

[0023] At the end of the rolling connection block 50301 where the regulation motor 50302 is installed, there are two symmetric regulation sliding grooves 50303. Inside the two regulation sliding grooves 50303, rolling stamping plates 50304 are slidably installed. A wrapping rubber sleeve 50307 is sleeved outside the two rolling stamping plates 50304, and the wrapping rubber sleeve 50307 is fixed to the end of the rolling connection block 50301. One end of the regulation thread ring 50309 is in sliding contact with the inner wall of the rolling stamping plate 50304. Elastic connection ropes 50314 are fixed on the inner sides of the two rolling stamping plates 50304. A hollow ring 50313 is fixed between the two elastic connection ropes 50314. The hollow ring 50313 is located outside the regulation lead screw 50308 and does not contact the regulation lead screw 50308. By driving the regulation lead screw 50308 to rotate through the regulation motor 50302, the regulation thread ring 50309 moves along the axial direction of the regulation lead screw 50308, thereby changing the distance dimension between the two regulation thread rings 50309, so as to change the end width of the lower rolling punch 5031 and the upper rolling punch 5032. And the existence of the elastic connection ropes 50314 ensures that after the regulation thread ring 50309 moves closer to the rolling connection block 50301, the two rolling stamping plates 50304 can move closer to each other.

[0024] At the end where the rolling stamping plate 50304 is slidably clamped inside the regulation sliding groove 50303, there is a through regulation guiding groove 50305. Inside the regulation guiding groove 50305, a anti - detachment pin 50306 is inserted. One end of the anti - detachment pin 50306 is inserted into the inside of the rolling connection block 50301, and the rolling stamping plate 50304 is slidably connected with the anti - detachment pin 50306. The position of the end of the rolling stamping plate 50304 is restricted by the anti - detachment pin 50306. The cooperation of the anti - detachment pin 50306 and the wrapping rubber sleeve 50307 ensures that the rolling stamping plate 50304 will not separate from the rolling connection block 50301 during the regulation process.

[0025] A reinforcing rib 50310 is fixed between the two ends of the rolling and stamping plate 50304. The reinforcing rib 50310 is in an X shape, and a through anti-interference sliding groove 50312 is provided in the middle part of the reinforcing rib 50310. The regulating threaded ring 50309 and the elastic connecting rope 50314 pass through the inside of the anti-interference sliding groove 50312. The strength of the rolling and stamping plate 50304 is increased by the reinforcing rib 50310, so as to ensure that the rolling and stamping plate 50304 will not be deformed or bent due to the extrusion between the rolling and stamping plate 50304 and the copper wire during the stamping and rolling of the copper wire.

[0026] As Figure 1 , Figures 5 to 7 shown, a Great Wall buckle moving mechanism 6 is fixed on the other side of the fixed seat 1 and the top cover 2. The Great Wall buckle moving mechanism 6 includes a first connecting plate 601 and a second connecting plate 602. One end of the first connecting plate 601 is fixedly connected to the top cover 2, and one end of the second connecting plate 602 is fixedly connected to the fixed seat 1. Side limiting baffles 603 are fixed on the front and back surfaces of the first connecting plate 601 and the second connecting plate 602. The distance between the two side limiting baffles 603 is the same as the width of the Great Wall buckle after rolling. The side limiting baffles 603 are used to guide and transport the Great Wall buckle after rolling, and cooperate with the wire guiding transmission frame 4 to ensure that the copper wire will not be offset or skewed during rolling.

[0027] The front and rear surfaces of the first connecting plate 601 and the second connecting plate 602 are both provided with moving sliding grooves 604. Inside the first connecting plate 601 and the second connecting plate 602, a moving motor 611 is fixed. The two output shaft ends of the moving motor 611 penetrate through the sides of the first connecting plate 601 and the second connecting plate 602, and the axis of the moving motor 611 coincides with the center point of the moving sliding groove 604. On the outer sides of both ends of the moving motor 611, a rotating plate 605 is fixed. Between the rotating plate 605 and the first connecting plate 601 and the second connecting plate 602, there is a moving plate 607. On the surfaces of the two moving plates 607 facing each other, a moving insertion block 612 is fixed. A rubber sleeve 608 is sleeved outside the moving insertion block 612. The moving plate 607 is in sliding contact with the first connecting plate 601 and the second connecting plate 602. At the end of the rotating plate 605 connected to the moving plate 607, there is a penetrating adjustment sliding groove 610. At the end of the moving plate 607 connected to the rotating plate 605, a moving connecting rod 606 is penetrated. One end of the moving connecting rod 606 passes through the inside of the adjustment sliding groove 610, and this end of the moving connecting rod 606 is slidably clamped inside the moving sliding groove 604. On the outer surface of the moving connecting rod 606, there is a connecting ring groove 609. The moving connecting rod 606 is clamped inside the connecting ring groove 609. By driving the rotating plate 605 to rotate with the moving motor 611, the rotating plate 605 is made to push the moving connecting rod 606 to slide reciprocally inside the moving sliding groove 604. When the moving connecting rod 606 slides reciprocally, it drives the moving plate 607 to perform a reciprocating motion. During the continuous movement of the moving plate 607, it pushes the rolled part of the copper wire to move, thereby realizing the movement of the copper wire, and the length of each movement of the copper wire is the same.

[0028] As Figure 1 , Figure 8 and Figure 9 shown, on the same side of the fixed seat 1 and the top cover 2, a wire guiding and transmitting frame 4 is installed. The wire guiding and transmitting frame 4 includes a first fixing frame 401 and a second fixing frame 402. The top end of the first fixing frame 401 is fixed to the side of the top cover 2, and the bottom end of the second fixing frame 402 is fixed to the side of the fixed seat 1. Between the first fixing frame 401 and the second fixing frame 402, a guiding plate 403 is fixed. Inside the guiding plate 403, two rows of symmetrically distributed guiding wheels 404 are installed. An axial positioning pin 406 is penetrated through the guiding wheel 404. The two ends of the positioning pin 406 are rotatably connected to the guiding plate 403 through roller bearings. On the outer surface of the guiding wheel 404, there is a guiding groove 405. The cross-section of the guiding groove 405 along the axis direction of the positioning pin 406 is V-shaped. The guided copper wire is guided and transmitted by the guiding wheel 404 with the guiding groove 405 on its outer surface, so as to prevent the copper wire from being skewed or displaced during the transmission process.

[0029] Working principle: First, insert the copper wire into the inner side of the guide plate 403 so that the side of the copper wire is located inside the guide groove 405, and push the copper wire to move between the fixed seat 1 and the top cover 2. At this time, the copper wire moves between the two rows of guide wheels 404 without any position deviation or deflection. When the end of the copper wire moves to the position between the first pressing block 501 and the second pressing block 502 closest to the rolling punch 503, turn on the power supply of the device. After the power is turned on, the first pressing hydraulic rod 510 and the second pressing hydraulic rod 511 are activated, and the first pressing plate 512 and the second pressing plate 513 approach each other, so that the first pressing block 501 and the second pressing block 502 approach each other and clamp the end of the copper wire. Subsequently, the upper hydraulic rod 506 and the lower hydraulic rod 507 are powered on and activated. After the upper hydraulic rod 506 is activated, it drives the upper rolling punch 5032 and the upper rolling limit block 505 to approach the copper wire through the upper moving plate 509. At the same time, after the lower hydraulic rod 507 is activated, it drives the lower rolling punch 5031 and the lower rolling limit block 504 to approach the copper wire through the lower moving plate 508. When the lower rolling punch 5031, the lower rolling punch 5031, the lower rolling limit block 504 and the upper rolling limit block 505 approach each other, the copper wire is extruded and rolled, so that the copper wire is bent to form a Great Wall buckle. After the copper wire is formed, the upper hydraulic rod 506, the lower hydraulic rod 507, the first pressing hydraulic rod 510 and the second pressing hydraulic rod 511 are activated again and drive the upper moving plate 509, the lower moving plate 508, the first pressing plate 512 and the second pressing plate 513 to reset. Next, the copper wire continues to move, and the unrolled part is moved to the position between the lower rolling punch 5031, the lower rolling punch 5031, the lower rolling limit block 504 and the upper rolling limit block 505. Subsequently, repeat the previous rolling operation. The formed part of the copper wire is clamped by the first pressing block 501 and the second pressing block 502, and then the unrolled part of the copper wire is rolled and formed by the lower rolling punch 5031, the lower rolling punch 5031, the lower rolling limit block 504 and the upper rolling limit block 505. During this process, the formed part of the copper wire will not be deformed. When rolling the Great Wall buckle of copper wires with different thicknesses, the regulating motor 50302 is driven to rotate the regulating screw rod 50308, so that the regulating threaded ring 50309 moves along the axis direction of the regulating screw rod 50308, thereby changing the distance between the two regulating threaded rings 50309, and thus changing the end widths of the lower rolling punch 5031 and the upper rolling punch 5032, so that the distance between the lower rolling punch 5031 and the upper rolling punch 5032 after they approach each other is the thickness of the copper wire, so as to roll copper wires with different thicknesses, and thus there is no need for multiple devices to roll copper wires with different thicknesses, achieving the reduction of production costs.
