[0002] To facilitate the transportation of metal wire and its processing into parts of different lengths during use, raw material manufacturers need to coil the wire for storage and transportation. When in use, the wire is then extracted, straightened to the required size, and then cut and separated for use. In the production process of screws, pins, and column metal connectors, the coiled wire is usually straightened and cut into the required size for manufacturing screws, pins, column connectors, etc. The cut wire is then processed into the required screws, pins, and other products. The existing metal wire straightening machine has a complex structure and is difficult to manufacture. Although it can automatically measure the straightening length well, it does not have an automatic cutting function. It is not convenient to use and is not conducive to promotion in small enterprises. For example: The patent with the authorization announcement number CN210996207U is named: An automatic wire straightening device. Although it improves convenience and accuracy in use, it has a complex structure and is difficult to manufacture, resulting in high manufacturing costs. Without the automatic cutting function, promotion and application have become disadvantages and have not been promoted well. Utility Model Content

The support frame is provided with a rolling mechanism, and the rolling mechanism is provided with symmetrical rolling wheels, and the rolling wheels are provided with pressure grooves for rolling the metal wire. The rolling wheels of the rolling mechanism can clamp the metal wire, and the motor controls the rotation of the two rolling wheels to clamp the metal wire in the pressure groove and push it forward into the straightening port; the straightening port includes a straightening component, and the straightening component is provided with a tightening port to cooperate with a tightening clamp ring, and the tightening clamp ring can adjust the tightening The size of the opening is determined by the tightening opening, which clamps the metal wire in the center. A cutting mechanism is provided at the upper end of the tightening opening; the cutting mechanism includes a telescopic cylinder and a cutting motor. The telescopic cylinder can control the raising or lowering movement of the cutting motor.

The rolling centers of the rolling wheels of the two rolling mechanisms are on the same axis. When the motors of the first rolling mechanism and the second rolling mechanism rotate, they drive the corresponding rolling wheels to rotate, and roll and push the metal wire entering the pressing groove. Under the clamping, rolling and pushing action of the rolling wheels of the two rolling mechanisms, the metal wire can be straightened more conveniently.

[0006] A positioning frame is provided in the second rolling mechanism of the rolling mechanism, and a straightening plate is installed in the positioning frame. The straightening plate is provided with a wire hole. The center of the wire hole is coaxial with the circle tangent to the pressure groove of the rolling wheels of the first rolling mechanism and the second rolling mechanism. When the metal wire passes through the pressure groove of the rolling wheel of the first rolling mechanism, the wire hole of the straightening plate, and the pressure groove of the rolling wheel of the second rolling mechanism, it is straightened under the action of the rolling wheels and the straightening plate.

[0007] A detachable straightening plate is provided in the positioning frame of the second rolling mechanism, and guide grooves are provided at the upper and lower ends of the positioning frame.

[0009] The rolling mechanism includes a clamping arm, a rolling wheel, a coupling, a tensioning shaft, a spring, a driving gear, a driven gear, and a support plate. Two mutually meshing driving gears are provided in the support plate. Any one of the driving gears is connected to the motor, and the rotation of the motor controls the meshing rotation of the two driving gears. Two mutually symmetrical guide arc holes are provided around the teeth of the two driving gears of the support plate.

[0011] The support frame supports the first rolling mechanism and the second rolling mechanism, so that the first rolling mechanism and the second rolling mechanism form a stable frame.

[0012] The length of the metal wire in the rolling mechanism that is clamped and pushed forward can be controlled by the number of revolutions of the motor. For example, when the motor rotates one revolution and stops, the metal wire is pushed forward 100MM; when the motor rotates two revolutions and stops, the metal wire is pushed forward 200MM. By setting the number of revolutions of the motor to control the length of the metal wire pushed forward, the cutting mechanism controls the cutting wheel to move downward to cut out the metal wire of the required length. The cutting length is easy to control, which is conducive to efficient straightening and cutting and coordinating the cutting.

Several rolling mechanisms cooperate with each other to clamp and push the metal wire, and the metal wire is rolled and straightened during the pushing process, which can quickly straighten the metal wire wound into a coil shape. The straightened metal wire enters the straightening port and is straightened again. Thereafter, the straightened metal wire is cut into lengths of a specific size by the automatic cutting mechanism for collection and use. The straightening component cooperates with the cutting mechanism, and has better stability during the cutting process, avoiding bending of the metal wire during cutting. At the same time, the straightening component can further straighten the metal wire. The equipment has a simple structure, low manufacturing cost, is more convenient to use, and is easier to promote and apply. Compared with existing equipment, it saves costs, integrates straightening and cutting functions, and is smaller in size, and is also better suitable for application in small enterprises.

The rolling centers of the rolling wheels 4 between the two rolling mechanisms are on the same axis. When the motors 18 of the first rolling mechanism 2 and the second rolling mechanism 3 rotate, they drive the corresponding rolling wheels 4 to rotate, and roll and push the metal wire 11 entering the pressing groove 5. Under the clamping, rolling and pushing action of the rolling wheels 4 of the two rolling mechanisms, the metal wire 11 can be straightened more conveniently.

[0023] The second rolling mechanism 3 of the rolling mechanism is provided with a positioning frame 9, and a straightening plate 10 is installed in the positioning frame 9. The straightening plate 10 is provided with a wire hole. The center of the wire hole is coaxial with the circle tangent to the groove 5 of the rolling wheel 4 of the first rolling mechanism 2 and the second rolling mechanism 3.

The central axis of the driven gear 6 can be in the guide arc hole 12 under the pulling force of the clamping arm 13. The position of the arc hole 12 is adjusted by arc motion along the guide arc hole 12. The two clamping arms 13 connected to the central axis of the driven gear 6 intersect and are connected to the tensioning shaft 15. The tensioning shaft 15 can pull the two clamping arms 13 to retract or expand. The tensioning shaft 15 passes through the axial hole of the coupling 14. A spring 16 and an adjusting nut 17 are provided at the end of the tensioning shaft 15. When the adjusting nut 17 is tightened, the elastic force of the spring 16 increases, and the two clamping arms 13 will be tightened and retracted, and the two driven gears 6 will be tightened to engage in the teeth around the corresponding driving gear 7; the driven gear 6 is fixedly connected to the rolling wheel 4 and is coaxial, and the rotation of the driven gear 6 controls the synchronous movement of the rolling wheel 4.

[0026] When the elastic force of the spring 16 tightens the two clamping arms 13, the two rolling wheels 4 approach each other and can clamp the metal wire 11.

[0028] The support frame 1 supports the first rolling mechanism 2 and the second rolling mechanism 3 so that the first rolling mechanism 2 and the second rolling mechanism 3 form a stable frame. A cutting mechanism is installed in the second rolling mechanism 3.

[0029] Two opposing straightening components 20 are provided directly in front of the rolling wheel 4 of the second rolling mechanism 3 of the support frame 1. The metal wire 11 extending forward from the pressure groove 5 of the second rolling mechanism 3 enters the tightening opening 21 of the first straightening component 20 and then enters the tightening opening 21 of the second straightening component 20. The cutting wheel 25 of the cutting mechanism can cut the metal wire 11 in the middle section of the two straightening components 20. The two straightening components 20 cooperate with the cutting mechanism to provide better stability during the cutting process, preventing the metal wire 11 from bending during cutting. At the same time, the straightening components 20 can further straighten the metal wire 11.

When the metal wire passes through the pressing groove 5 of the first rolling mechanism 2, the wire hole of the straightening plate 10, the pressing groove 5 of the second rolling mechanism 3, and the straightening component 20, it is better pulled under the positioning and straightening action of the rolling wheels 4, the straightening plate 10, and the straightening component 20. The straightened metal wire 11 enters the straightening component 20 at the end. When the motor 18 stops, the rolling wheel 4 stops rotating, and the metal wire 11 stops rolling and pushing. At this time, the cutting motor 24 rotates to control the cutting wheel 25 to rotate, and the telescopic cylinder 23 controls the cutting motor 24 to descend, and the cutting wheel 25 moves downward to cut the metal wire 11 passing through the tightening mouth 21. After the metal wire 11 is cut and broken, the telescopic cylinder 23 controls the cutting motor 24 to rise, and the cutting wheel 25 rises upward, away from the metal wire 11, completing a cutting operation. When the motor 18 of the first rolling mechanism 2 and the second rolling mechanism 3 rotates again, the metal wire 11 is rolled and pushed forward again. When the set length is reached, the motor 18 stops, the rolling wheel 4 stops rotating, the metal wire 11 stops rolling and pushing, and is then cut by the cutting mechanism. The straightening and cutting are continuously circulated, and a section of material is completed with each cycle. Yes, but not limited to, by adjusting the tightening clamp 22 so that the tightening opening 21 of the end straightening part 20 is larger than the tightening opening 21 of the front straightening part 20, the metal wire 11 extending from the front tightening opening 21 can more easily enter the tightening opening 21 of the end straightening part 20.

[0031] The length of the metal wire 11 that is clamped and pushed forward can be controlled by the number of revolutions of the motor 18. For example, when the motor 18 rotates one revolution and stops, the metal wire 11 is pushed forward 100MM; when the motor 18 rotates two revolutions and stops, the metal wire 11 is pushed forward 200MM. By setting the number of revolutions of the motor 18 to control the length of the metal wire 11 that is pushed forward, the cutting mechanism can cut out the required length. The cutting length is easy to control, which is conducive to efficient straightening and cutting coordination.

[0032] The motor 18 can be any one of a stepping motor, a steering gear, a servo motor, and a gear reduction motor; the telescopic cylinder 23 can be any one of a hydraulic telescopic cylinder, an electric screw telescopic cylinder, and a pneumatic telescopic cylinder.
