[0021] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the utility model is a high-precision slitting equipment for the production of gold and silver wires, including a first positioning bar 1, a second positioning bar 16, a metal wire 10 and a pressure rod 2. The first positioning bar 1 and the second positioning bar 16 are arranged in a close relationship, and the first positioning bar 1 and the second positioning bar 16 are provided with L-shaped grooves on the opposite surfaces. The L-shaped grooves are combined to form a U-shaped groove 19. The metal wire 10 is axially placed in the U-shaped groove 19. The pressure rod 2 is arranged above the first positioning bar 1 and the second positioning bar 16. The bottom of the pressure rod 2 protrudes to form an extrusion portion 17 matching the U-shaped groove 19. The extrusion portion 17 is inserted into the U-shaped groove 19 and is arranged to conflict with the metal wire 10. A pressure plate 3 is provided above the pressure rod 2. The pressure rod 2 is provided with a plurality of positioning openings that pass through the pressure rod 2 and the extrusion portion 17. Cutting blades 4 are provided in the positioning openings. One end of the cutting blade 4 is installed on the pressure plate 3. Support plates 9 are installed at both ends of the first positioning bar 1, and a driving mechanism for straightening the metal wire 10 is installed above the support plates 9.

[0023] In this embodiment, the driving mechanism includes a fixed frame 8, a motor 12, a driving wheel 11, a positioning cylinder 13, a positioning column 14 and a compression spring. The driving wheel 11 is installed on the rotating shaft of the motor 12, and the outer ring of the driving wheel 11 is arranged to abut against the outer wall of the metal wire 10. One end of the fixed frame 8 is installed on the support plate 9, and the other end extends to the top of the motor 12. The positioning cylinder 13 is installed on the fixed frame 8. One end of the positioning column 14 is inserted into the interior of the positioning cylinder 13 and is installed with a compression spring. The other end of the compression spring is installed on the inner wall of the positioning cylinder 13, and the other end of the positioning column 14 is installed on the motor 12.

[0024] In this embodiment, an L-shaped plate 5 is installed on the outer surface of the second positioning bar 16, and a first cylinder 6 and a second cylinder 7 are installed on the L-shaped plate 5. The piston rod of the first cylinder 6 passes through the L-shaped plate 5 and is installed on the pressure plate 3. The piston rod of the second cylinder 7 passes through the L-shaped plate 5 and is installed with a fixed plate. The other end of the fixed plate is installed on the pressure rod 2.

[0025] In this embodiment, an avoidance groove 18 is provided on the bottom surface of the U-shaped groove 19 opposite the cutting blade 4. After the cutting blade descends and cuts the wire, the lower end of the cutting blade can be inserted into the avoidance groove to ensure the cutting depth.

[0026] In this embodiment, the first positioning bar 1 and the second positioning bar 16 are fixedly connected by a hinge, and a base 15 is installed on the outer side of the first positioning bar 1 and the second positioning bar 16. After the first positioning bar and the second positioning bar are placed on the platform, the opposite surfaces of the first positioning bar and the second positioning bar are pressed against each other, making it impossible to open outward.

[0027] In this embodiment, arc-shaped grooves are provided on the supporting plates 9, and both ends of the metal wire 10 are arranged in the arc-shaped grooves, thereby increasing the contact area with the metal wire, wherein the metal wire is gold or silver wire.

[0028] When in use, the second cylinder is started to retract the piston rod of the second cylinder. The movement of the piston rod drives the fixed plate and the pressure rod, causing the pressure rod to rise, thereby opening the U-shaped groove. The metal wire can be directly placed in the U-shaped groove, and the two ends of the metal wire can be placed in the arc groove. The motor is pressed down by the rebound of the compression spring. The movement of the motor drives the driving wheel, so that the outer ring of the driving wheel is pressed against the outer wall surface of the metal wire.

[0029] After the above is completed, the motors are started to rotate in opposite directions. The rotation of the motors drives the driving wheels. The pressure and friction between the driving wheels and the metal wire pull the metal wire outward, so that the metal wire is straightened and set inside the U-shaped groove.

[0030] After straightening, the second cylinder and the first cylinder are started, so that the piston rod of the second cylinder extends and drives the fixed plate and the pressure rod to move downward. The movement of the pressure rod drives the extrusion part, so that the extrusion part can flatten the wire and position it. After the piston rod of the first cylinder is extended, it can drive the pressure plate to move downward. The movement of the pressure plate drives the cutting blade. The descending cutting blade can complete multiple cutting operations at one time, greatly increasing efficiency.

[0031] After the cutting is completed, the first positioning bar and the second positioning bar can be lifted up so that the first positioning bar and the second positioning bar can be opened outward with the hinge as the center. After opening, the cut metal wire can be quickly taken out.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
