The first cutting blade is located at the far end of the wire outlet nozzle, and the second cutting blade is located at the near end of the wire outlet nozzle. The first cutting blade is provided with a retaining plate and an elastic component. The retaining plate can slide back and forth along the cutting direction. The elastic component is arranged between the retaining plate and the first cutting blade, and the retaining plate extends out of the cutting edge of the first cutting blade through elastic force. When the first and second cutting blades approach each other, the retaining plate first contacts the metal wire and presses the metal wire tightly between the second cutting blade and the retaining plate.

[0005] Furthermore, the elastic component is a spring, one end of which is connected to a retaining plate and the other end to a cutting blade. A limiter is provided on the retaining plate, and the limiter abuts against the cutting blade to prevent the retaining plate from sliding out of the cutting blade by the elastic force.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0012] A wire cutting device includes a first cutting blade and a second cutting blade arranged opposite to each other. The first cutting blade and the second cutting blade are arranged outside the wire outlet end of the wire outlet nozzle along the wire conveying direction. The first cutting blade is located at the far end of the wire outlet nozzle, and the second cutting blade is located at the near end of the wire outlet nozzle. The first cutting blade is provided with a retaining plate and an elastic component. The retaining plate can slide back and forth along the cutting direction. The elastic component is arranged between the retaining plate and the first cutting blade, and the retaining plate extends out of the cutting edge of the first cutting blade through elastic force. When the first and second cutting blades approach each other, the retaining plate first contacts the metal wire and presses the metal wire tightly between the second cutting blade and the retaining plate.

[0013] In one embodiment, the movement direction of the first cutting blade and the second cutting blade is set to the vertical direction. When set to the vertical direction, the first cutting blade can be defined as the upper cutting blade and the second cutting blade can be defined as the lower cutting blade.

[0014] In one embodiment, the movement direction of the first and second cutting blades is set to the horizontal direction.

[0015] In one embodiment, the movement direction of the first and second cutting blades can also be set to an inclined direction, such as 45°, 60°, etc.

[0016] In one embodiment, the elastic component is a spring, one end of which is connected to a retaining plate and the other end to a cutting blade. A limiter is provided on the retaining plate, and the limiter abuts against the cutting blade to prevent the retaining plate from sliding out of the cutting blade by the elastic force.

[0017] Example See Figure 1 and Figure 2 This is a schematic diagram of the metal wire cutting device in this application, wherein... Figure 1 Main view, Figure 2 This is a side view. Combined with... Figure 1 and Figure 2 The wire cutting device of this application includes a fixing plate 1 for mounting other components; a wire outlet 9 is installed on the fixing plate 1. After the wire 11 comes out through the wire outlet 9, it enters the cutting area and is cut according to the length requirement. The operation is repeated after subsequent wires 11 come out through the wire outlet 9.

[0018] The cutting area is equipped with an upper cutting blade 3 and a lower cutting blade 5 that cooperate with each other. The upper cutting blade 3 and the lower cutting blade 5 cut the metal wire 11 between them by bringing them close together. In this application, a retaining plate 8 is provided on the upper cutting blade 3 and the lower cutting blade 5. The retaining plate 8 is used to press and hold the metal wire 11 before the upper cutting blade 3 and the lower cutting blade 5 come into contact, and at the same time, it maintains the position of the metal wire 11 after the cutting blade 3 and the lower cutting blade 5 have finished cutting the metal wire 11.

[0019] Example, combination Figure 3 The retaining plate 8 is mounted on the upper cutting blade 3 and is movably connected to the upper cutting blade 3. The retaining plate 8 can move up and down on the upper cutting blade 3. When no cutting operation is performed, the lower edge of the retaining plate 8 is lower than the cutting edge of the upper cutting blade 3. The upper cutting blade 3 is also provided with an elastic component to keep the lower edge of the retaining plate 8 lower than the cutting edge of the upper cutting blade 3.

[0020] As the upper cutting blade 3 and the lower cutting blade 5 approach each other during relative movement, the holding plate 8 first contacts the metal wire 11, pressing the metal wire 11 into the groove of the lower cutting blade 5. As the upper cutting blade 3 and the lower cutting blade 5 continue to approach each other, the metal wire 11 is cut by the cutting action of the blades of the upper cutting blade 3 and the lower cutting blade 5. At this time, the metal wire 11 is still pressed on the lower cutting blade 5 by the holding plate 8, thus keeping the metal wire 11 in an extended state so that it can be clamped and fed in subsequent repeated cutting processes.

[0021] In this application, the retaining plate 8 is mounted on the upper cutting blade 3, which should be located at the far end of the wire outlet 9, so that the lower end face of the retaining plate 8 and the upper end face of the lower cutting blade 5 can partially or even completely overlap when they are close together, and the overlapping part is used to press and retain the metal wire 11.

[0022] Combination Figure 1 and Figure 2In one embodiment, a groove is provided on the front side of the upper cutting blade 3, and a through hole is provided in the upper cutting blade 3, which is connected to the groove. The retaining plate 8 is installed on the upper cutting blade 3 through the through hole and can slide up and down in the through hole. A spring 7 is provided in the groove as an elastic component. One end of the spring 7 abuts against the upper edge of the groove, and the other end of the spring 7 abuts against the retaining plate 8, so that the retaining plate 8 can move downward under the action of the spring force of the spring 7, and when there is no external force, the lower edge of the retaining plate 8 is kept lower than the cutting edge of the upper cutting blade 3. The upper end of the retaining plate 8 passes through the upper cutting blade 3 and then a limiter 6 is fixed. The limiter 6 is used to limit the position of the retaining plate 8 and prevent the retaining plate 8 from falling off the upper cutting blade 3.

[0023] Combination Figure 4 The fixed plate 1 is also equipped with a sliding assembly 2, which includes a slide rail 14 and a slider 13. At least two sliders 13 are provided on the slide rail 14 to fix the upper slide plate 12 and the lower slide plate 15 respectively, and fix the upper cutting blade 3 on the upper slide plate 12 and the lower cutting blade 5 on the lower slide plate 15. The upper cutting blade 3 and the lower cutting blade 5 are cut in relative motion and the metal wire 11 is realized by the sliding of the slider 13 along the slide rail 14.

[0024] In one embodiment, two slide rails 14 are provided and are arranged parallel to each other on both sides of the wire outlet 9. Two sliders 13 are provided on each slide rail 14 to ensure the stability of the relative movement process of the upper cutting blade 3 and the lower cutting blade 5.

[0025] In one embodiment, a motion cylinder 4 is configured to drive the slider 13 to move relative to each other under the action of air pressure, and the two ends of the cylinder 4 are respectively fixed to the two sliders 13.

[0026] In one embodiment, a wire-retrieving claw 10 is also installed on the fixing plate 1. The wire-retrieving claw 10 is arranged outside the wire outlet end of the wire outlet 9 along the wire conveying direction of the metal wire 11. When the upper cutting blade 3 and the lower cutting blade 5 move relative to each other and cut the metal wire 11, the holding plate 8 and the lower cutting blade 5 cooperate to keep the metal wire 11 in an extended state. At this time, the wire-retrieving claw 10 clamps the metal wire 11 and pulls it outward, so that it can be cut again.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
