DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a precision copper rod drawing device, comprising a processing table 1, an electric slide 2 is fixedly installed on the processing table 1, a cylinder 3 is fixedly installed on the electric slide 2, two groups of clamping jaws 4 are hinged on the electric slide 2, and a connecting rod 5 is hinged at the bottom of the clamping jaw 4, and one end of the connecting rod 5 away from the clamping jaw 4 is hinged at the piston end of the cylinder 3. The cylinder 3 is started to pull the two groups of connecting rods 5, so that the two groups of connecting rods 5 squeeze the two groups of clamping jaws 4, so that the two groups of clamping jaws 4 are close to each other and clamp the copper rod, a boss 6 is fixedly installed on the processing table 1, and a collecting box 61 is movably connected to the inner wall of the boss 6. The collecting box 61 can be used to collect the copper chips cleaned by the nylon brush 81. An adjusting mechanism 7 is arranged on the boss 6. By setting the adjusting mechanism 7, a suitable horn hole 75 can be freely selected according to production needs. A cleaning mechanism 8 for cleaning copper rod debris is arranged on the boss 6. By setting the cleaning mechanism 8, the copper chips on the inner wall of the horn hole 75 can be cleaned to avoid material waste.

[0024] The above-mentioned adjusting mechanism 7 includes a rotating shaft 71, a worm 72, a limiting frame 73, a mold plate 74, a worm wheel 76, a knob 77, and a limiting rod 78; the rotating shaft 71 is rotatably connected to the inner wall of the boss 6, and the outer wall of the rotating shaft 71 is fixedly installed with a mold plate 74, and the mold plate 74 is provided with four groups of horn holes 75 with different apertures. By rotating the mold plate 74, the four groups of horn holes 75 with different apertures can be freely selected as needed, and the horn holes 75 with the required aperture can be rotated to the top of the boss 6. The outer wall of the rotating shaft 71 is fixedly installed with a worm wheel 76, and the worm 72 is rotatably connected to the inner wall of the boss 6, and the worm 72 passes through the boss 6 and is fixedly installed with a knob 77. The worm 72 and the worm wheel 76 is engaged, and the worm screw 72 is rotated by turning the knob 77. At the same time, the worm wheel 76 engaged therewith can drive the rotating shaft 71 to rotate, so that the rotating shaft 71 drives the mold plate 74 to rotate. The limit frame 73 is slidably connected to the side wall of the boss 6, and the inner wall of the limit frame 73 is rotatably connected with two groups of limit rods 78. The end of the limit rod 78 away from the limit frame 73 passes through the boss 6 and fits against the inner wall of the horn hole 75, and the limit rod 78 fits against the penetration of the boss 6. The limit frame 73 is used to push the limit rod 78 toward the inside of the boss 6, so that the two groups of limit rods 78 enter the inside of the two groups of horn holes 75. At this time, the two groups of limit rods 78 can be used to limit the mold plate 74 in cooperation with the horn holes 75.

[0025] The cleaning mechanism 8 comprises a nylon brush 81, a rotating rod 82, a handle 83 and a transmission belt 84. The end of the limiting rod 78 away from the limiting frame 73 is fixedly mounted with a nylon brush 81, and the nylon brush 81 is attached to the inner wall of the horn hole 75. The horn hole 75 may rub off some copper chips when pulling the copper rod, and the copper chips on the inner wall of the horn hole 75 can be cleaned by the rotation of the nylon brush 81, so that the fallen copper chips enter the interior of the collection box 61 for centralized treatment, thereby avoiding material waste. The inner wall of the limiting frame 73 is rotatably connected with a rotating rod 82, and the rotating rod 82 passes through the limiting frame 73. One end of the rotating rod 82 is fixedly mounted with a handle 83, and the other end of the rotating rod 82 is transmission-connected to the limiting rod 78 through a transmission belt 84. After the two groups of limiting rods 78 enter the horn hole 75, the rotating rod 82 is rotated by the handle 83, and the two groups of limiting rods 78 can be driven to rotate synchronously with the transmission belt 84, so that the limiting rod 78 drives the nylon brush 81 to rotate.

[0026] Working principle: Pass the copper rod through the trumpet hole 75 and place it between the two groups of clamping jaws 4, then start the cylinder 3 to pull the two groups of connecting rods 5, so that the two groups of connecting rods 5 squeeze the two groups of clamping jaws 4, so that the two groups of clamping jaws 4 are close to each other and clamp the copper rod, and then use the electric slide 2 to pull the copper rod. When it is necessary to pull copper rods of different diameters, first pull the limit frame 73 so that the limit frame 73 drives the limit rod 78 to move to the outside of the boss 6, and the limit rod 78 is separated from the trumpet hole 75, and then the worm 72 is rotated by the knob 77. At the same time, the worm gear 76 engaged with it can drive the rotating shaft 71 to rotate, so that the rotating shaft 71 drives the mold plate 74 to rotate, and the mold plate 74 is rotated. The rotation can freely select four groups of speaker holes 75 with different apertures as needed. The speaker hole 75 of the required aperture can be rotated to just above the boss 6, and then the limiting frame 73 is used to push the limiting rod 78 toward the inside of the boss 6, so that the two groups of limiting rods 78 enter the inside of the two groups of speaker holes 75. At this time, the two groups of limiting rods 78 can be used to limit the mold plate 74 in conjunction with the speaker holes 75 to avoid accidentally touching the knob 77 and causing the worm 72 to rotate, thereby causing the worm wheel 76, the rotating shaft 71 and the mold plate 74 to rotate. After the above operation, the appropriate speaker hole 75 can be freely selected according to production needs, without the need to frequently disassemble the mold, and it is more convenient to use.

[0027] After the two sets of limiting rods 78 enter the horn hole 75, the rotating rod 82 is rotated by the handle 83, and the transmission belt 84 can drive the two sets of limiting rods 78 to rotate synchronously, so that the limiting rods 78 drive the nylon brush 81 to rotate. The horn hole 75 may rub off some copper chips when pulling the copper rod, and the rotation of the nylon brush 81 can clean the copper chips on the inner wall of the horn hole 75, so that the fallen copper chips enter the interior of the collection box 61 for centralized treatment, saving costs and avoiding material waste.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
