[0029] like Figure 7-8 As shown, this example can achieve the effect of continuously drawing the metal wire thinner.

[0030] Since the cable manufacturing device includes a vertical plate 301, a plurality of wire drawing holes 303 are arranged on the vertical plate 301 from top to bottom, and the wire drawing holes 303 gradually become smaller from top to bottom. A clamping block 302 is arranged on the front and rear sides of each wire drawing hole 303. The clamping block 302 is driven to slide by a hydraulic cylinder, so that the metal wire can pass through the plurality of wire drawing holes 303 in turn, and the wire drawing holes 303 gradually become smaller from top to bottom, thereby continuously drawing the metal wire thinner. The two clamping blocks 302 at the wire drawing hole 303 can be clamped on the metal wire, thereby fixing the clamping position of the metal wire at the wire drawing hole 303 here.

[0031] like Figure 7-8 As shown, this example can achieve the effect of drawing the metal wire by passing the metal wire through a plurality of drawing holes 303 in sequence.

[0032] Since a connecting piece 306 is provided between two adjacent wire drawing holes 303, the connecting piece 306 is fixed to the vertical plate 301 by screws, a cross frame 304 is welded on the connecting piece 306, a slider 307 is slidably connected to the cross frame 304, and a rotating wheel 305 is rotatably connected to the front side of the slider 307, so that after the metal wire passes through the first wire drawing hole 303, the end of the metal wire can be fixed on the second wire drawing hole 303, and then the rotating wheel 305 is hooked at the bending part of the metal wire, and then the slider 307 is driven to move outward along the cross frame 304, and then the rotating wheel 305 is driven to move outward to pull the metal wire, so that the metal wire passes through the first wire drawing hole 303, and then the metal wire is drawn, and then the metal wire is drawn through multiple wire drawing holes 303 in turn.

[0033] like Figure 7-8 As shown, this example can achieve the effect of driving the slider 307 to move outward on the cross frame 304.

[0034] Since a motor is fixed to the outer end of the cross frame 304 , a screw rod 308 is fixed to the output shaft of the motor, and the screw rod 308 cooperates with the slider 307 through a thread, the motor can drive the screw rod 308 to rotate, thereby driving the slider 307 to move outward on the cross frame 304 .

[0035] like Figure 9-10 As shown, this example can achieve the effect of pulling the metal wire outward to complete the final wire drawing effect.

[0036] Since a crossbeam 401 is welded to the right side of the vertical plate 301, a clamping seat 404 is slidably connected to the crossbeam 401, and two guide rods 402 are welded to the rear side of the clamping seat 404, and a clamping seat 1 403 is slidably connected to the two guide rods 402. The clamping seat 1 403 is driven to slide by a hydraulic cylinder. When the metal wire passes through the last drawing hole 303, it is clamped at the end of the metal wire by the clamping seat 1 403 and the clamping seat 2 404, and then the clamping seat 1 403 and the clamping seat 2 404 are driven to slide outward along the crossbeam 401, thereby pulling the metal wire outward to complete the final wire drawing.

[0037] like Figure 9-10 As shown, this example can achieve the effect of driving the second clamping seat 404 to slide on the beam 401.

[0038] Since a right plate 405 is welded to the right end of the beam 401, a ring 406 is welded to the lower end of the right plate 405, a motor is connected to the right plate 405 via screws, a screw rod 407 is connected to the output shaft of the motor, and the screw rod 407 cooperates with the clamping seat 404 via threads. The motor can drive the screw rod 407 to rotate, thereby driving the clamping seat 404 to slide on the beam 401.

[0039] like Figure 4-8 As shown, this example can achieve the effect of making the metal wire dip into the molten plastic in the melting box 101.

[0040] Since two pillars 104 are welded to the lower end of the vertical plate 301, the two pillars 104 are fixed on the inner bottom surface of the melting box 101, and the melting box 101 is provided with an electric heating wire. Inclined plates 102 are provided on the left and right sides of the melting box 101, and a limiting groove 103 is provided on the inclined plate 102 on the left side. The two pillars 104 can support the vertical plate 301 above the melting box 101, and the PVC can be melted in the melting box 101. The metal wire after the final wire drawing is passed through the ring 406, and then the metal wire is immersed in the molten plastic in the melting box 101, so that the PVC material is coated on the outside of the metal wire, and finally the metal wire coated with the PVC material comes out from the limiting groove 103, and the limiting groove 103 guides the exit position of the metal wire, and the metal wire is pulled out of the melting box 101 and then cooled.

[0041] like Figure 4-6 As shown, this example can achieve the effect of fully bonding the metal wire to the PVC material.

[0042] Since each of the pillars 104 is slidably connected with a sliding sleeve 105, two round rods 106 are welded between the two sliding sleeves 105, a rear pillar 205 is welded on the rear side of the melting box 101, a flat rod 206 is welded on the upper part of the rear pillar 205, a seat plate 201 is slidably connected to the flat rod 206, and a plurality of toggle rods 204 are welded on the front and rear edges of the lower side of the seat plate 201, the metal wire can pass between the plurality of toggle rods 204 and between the two round rods 106, and slide back and forth on the flat rod 206 through the seat plate 201, thereby driving the plurality of toggle rods 204 to move back and forth, and then driving the metal wire to shake back and forth in the melted PVC material through the plurality of toggle rods 204, the two sliding sleeves 105 can slide vertically on the two pillars 104, thereby driving the two round rods 106 to move up and down, and then driving the metal wire to shake up and down in the melted PVC material, thereby making the metal wire fully adhere to the PVC material.

[0043] like Figure 4-6 As shown, this example can achieve the effect of driving the two round rods 106 to move up and down while driving the multiple toggle rods 204 to move forward and backward.

[0044] Since a compression spring is fixed to the rear side of the seat plate 201, the rear end of the compression spring is fixed to the rear column 205, a sloped rod 202 is fixed to the upper side of the seat plate 201, the left side of the sloped rod 202 is a slope, and a blocking rod 203 is fixed to the right end of the slope, a track 109 is provided on the front side of the melting box 101, a slide seat 108 is slidably connected to the track 109, a cylinder 107 is fixed to the upper side of the slide seat 108, the cylinder 107 is pressed on the slope on the sloped rod 202, the slide seat 108 is driven to slide by a hydraulic cylinder, one end of the articulated rod 110 is hinged to the slide seat 108, and the other end of the articulated rod 110 is hinged to the sliding sleeve 105 located on the front side, and the compression spring moves the seat plate 201 forward. The dynamic force makes the seat plate 201 and multiple toggle rods 204 always have a tendency to move forward, which can drive the slide 108 to move left and right on the track 109, and then drive the two sleeves 105 and the two round rods 106 to move up and down through the hinge rod 110. When the slide 108 and the cylinder 107 move to the right, the inclined rod 202 can be driven to move backward, and then the seat plate 201 and the multiple toggle rods 204 can be driven to move backward. When the slide 108 and the cylinder 107 move to the left, the seat plate 201 and the multiple toggle rods 204 move forward due to the action of the compression spring, and then the two round rods 106 can be driven to move up and down while driving the multiple toggle rods 204 to move forward and backward.
