[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The embodiment of the present application discloses a circular wire drawing auxiliary device for a metal workpiece.

[0038] Reference Figure 1 and Figure 2A circular wire drawing auxiliary device for metal workpieces includes a machine base 1, a wire drawing disk 2, a driving component 3 and an electromagnet 4. The wire drawing disk 2 is used for placing the workpiece. The bottom wall of the wire drawing disk 2 is connected to a rotating rod 5. The axis of the wire drawing disk 2 and the axis of the rotating rod 5 are located on the same vertical line. The end of the rotating rod 5 away from the wire drawing disk 2 is rotatably connected to the machine base 1. The driving component 3 is used to drive the wire drawing disk 2 to rotate. The driving component 3 is fixed to the machine base 1. A notch is provided on the top wall of the wire drawing disk 2. The electromagnet 4 is fixed and embedded in the notch on the top wall of the wire drawing disk 2. The rotating part is fixedly connected to a power supply component 6, which is electrically connected to the electromagnet 4. In this embodiment, the wire drawing disk 2 adopts a wooden disc.

[0039] When a metal workpiece is subjected to a wire drawing process, the workpiece is placed on the wire drawing disk 2, and the position of the workpiece is adjusted so that the center of the workpiece is located on the rotation axis of the rotating rod 5. The power supply component 6 is turned on, and the electromagnet 4 is energized to adsorb the metal workpiece so that the workpiece is stably placed on the wire drawing disk 2, thereby reducing the possibility of movement of the metal workpiece. The driving component 3 is started, and the driving component 3 drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the wire drawing disk 2 to rotate, thereby rotating the metal workpiece and pressing sandpaper on the surface of the rotating metal workpiece to achieve wire drawing on the metal surface, thereby reducing the possibility of the metal workpiece moving on the wire drawing disk 2 and causing the wire drawing line to be disordered, thereby improving the wire drawing quality of the metal surface.

[0040] In order to improve the rotation stability of the rotating rod 5 , a sleeve 11 is fixedly connected to the top of the base 1 , the rotating rod 5 is inserted into the sleeve 11 , and the rotating rod 5 is rotatably connected to the sleeve 11 , thereby reducing the possibility of shaking of the rotating rod 5 .

[0041] The driving assembly 3 includes a driving member 31, a first gear 32, a rack 33 and a second gear 34. The driving member 31 is fixedly connected to the top of the machine base 1, and the output end of the driving member 31 is fixed to the first gear 32. The rack 33 is arranged around and meshes with the first gear 32 and the second gear 34. The second gear 34 is fixedly connected to the end of the rotating rod 5 away from the drawing disk 2. In this embodiment, the driving member 31 adopts a driving motor.

[0042] When the rotating rod 5 is rotated, the driving member 31 is started, and the driving member 31 drives the first gear 32 to rotate. The rotation of the first gear 32 drives the rack 33 and the second gear 34 to rotate, thereby driving the rotating rod 5 to rotate, thereby improving the rotation stability of the rotating rod 5, reducing the possibility of the rotating rod 5 getting stuck and causing the wire drawing line to be disordered, and further improving the wire drawing quality of the metal surface.

[0043] A control box 7 is installed on the top of the base 1. The control box 7 is electrically connected to the driving member 31, so as to control the start and stop of the driving member 31 and improve the convenience of operation.

[0044] The power supply assembly 6 includes a battery 61 and a switch key 62. The battery 61 is fixedly connected to the side wall of the rotating part. The battery 61 is electrically connected to the switch key 62. The electromagnet 4 is electrically connected to the battery 61 and the switch key 62. The electromagnet 4, the battery 61 and the switch key 62 rotate along with the rotation of the rotating rod 5, thereby reducing the possibility of the electromagnet 4, the battery 61 and the switch key 62 spinning when the three are connected by wires. The switch key 62 is installed at the edge of the top wall of the wire drawing disk 2, which is convenient for controlling the magnetic attraction and power supply of the electromagnet 4 and improving the convenience of operation.

[0045] A sliding groove 21 is provided through the top wall of the wire drawing disk 2. The center of the wire drawing disk 2 is located in the extension direction of the sliding groove 21. The sliding grooves 21 are equidistantly arranged along the axial circumference of the wire drawing disk 2. A positioning member 8 is slidingly connected in the sliding groove 21. The positioning member 8 is composed of multiple cylinders connected coaxially. The positioning member 8 rolls on the groove wall of the sliding groove 21 to improve the sliding smoothness of the positioning member 8 on the wire drawing disk 2. In order to achieve the positioning of the workpiece, a positioning member 8 is matched in each sliding groove 21, and the distance between each positioning member 8 and the rotation axis centerline of the rotating rod 5 is consistent. The wire drawing disk 2 is provided with a regulating component 9, and the regulating component 9 is used to control the positioning member 8 to slide along the sliding groove 21 with the same displacement.

[0046] When the workpiece is subjected to wire drawing, the center of the workpiece needs to be located on the rotation axis of the rotating rod 5. When the workpiece is positioned, it is placed on the wire drawing disk 2, and the regulating component 9 is activated. The regulating component 9 controls the positioning member 8 to move the same distance on the wire drawing disk 2, and the positioning member 8 rolls in the sliding groove 21 until all the circumferentially arranged positioning members 8 are tightly pressed against the peripheral wall of the workpiece, so that the center of the workpiece is located on the rotation axis of the rotating rod 5. While quickly positioning the workpiece, the accuracy of the workpiece placement position is improved, and the possibility of the workpiece position being offset, resulting in the center position of the circular wire drawing being offset from the center of the workpiece, is reduced, thereby further improving the metal surface drawing quality.

[0047] Reference Figure 2 and Figure 3 The regulating component 9 is located at the bottom of the wire drawing disk 2, and the regulating component 9 includes a third gear 91, a plurality of toothed rods 92 and a plurality of sliding rods 93. The bottom wall of the third gear 91 is rotatably connected to the top wall of the wire drawing disk 2, and the axis of the third gear 91 is located on the same vertical line as the axis of the wire drawing disk 2. The top wall of the toothed rod 92 is slidably connected to the bottom wall of the wire drawing disk 2. One end of the toothed rod 92 is fixedly connected to the sliding rod 93, and the end of the toothed rod 92 away from the sliding rod 93 is meshed with the third gear 91. The sliding rod 93 is slidably connected to the positioning member 8. The toothed rod 92 and the sliding rod 93 are equidistantly arranged circumferentially along the axis of the third gear 91, and one positioning member 8 matches one toothed rod 92 and one sliding rod 93.

[0048] When the positioning member 8 is moved, the third gear 91 is rotated, and the third gear 91 drives the toothed rod 92 to slide on the drawing disk 2. The movement of the toothed rod 92 drives the sliding rod 93 to move. The positioning member 8 is directed along the sliding groove 21 under the action of the sliding rod 93 and the toothed rod 92. Therefore, the positioning member 8 can realize synchronous movement under the rotation of the third gear 91, and the workpiece is quickly clamped and positioned, thereby improving the convenience and accuracy of workpiece positioning.

[0049] The moving range of the positioning member 8 is related to the length of the sliding groove 21. The two ends of the length direction of the sliding groove 21 are the two end ends of the movement of the positioning member 8. When the positioning member 8 is located at the end of the sliding groove 21 away from the center of the drawing disk 2, at this time, the positioning member 8 is located at the end of the sliding member close to the gear rod 92, and the third gear 91 just meshes with the gear rod 92. When the positioning member 8 moves toward the center of the drawing disk 2, the positioning member 8 slides along the direction of the sliding groove 21 close to the center of the drawing disk 2. At the same time, the positioning member 8 slides along the end of the sliding member away from the gear rod 92.

[0050] In this embodiment, three positioning members 8 are provided. To reduce the possibility of collision when the gear rod 92 moves, the length of the sliding groove 21 is less than one fourth of the circumference of the tooth root of the third gear 91 .

[0051] Reference Figure 4 To facilitate the rotation of the third gear 91 , an adjusting member 911 is fixedly connected to the side wall of the third gear 91 .

[0052] The adjusting member 911 is rotatably connected to a rolling member 912 . An annular groove 22 is provided on the outer wall of the wire drawing disk 2 . The rolling member 912 rolls with the groove wall of the annular groove 22 .

[0053] When the adjusting rod is adjusted, the rolling element 912 rolls along the annular groove 22, thereby improving the sliding smoothness of the adjusting rod and reducing the possibility of damage to the adjusting rod.

[0054] The adjusting member 911 is threadedly connected with a fastener 913 , and one end of the fastener 913 away from the adjusting member 911 is tightly pressed against the top wall of the wire drawing disk 2 .

[0055] After the positioning member 8 positions the workpiece, the fastener 913 is screwed to reduce the possibility of the adjustment rod rotating arbitrarily when the drawing disk 2 rotates, causing inconvenience in the drawing surface treatment, thereby reducing the possibility of confusion of the metal surface drawing wire and improving the drawing quality.

[0056] The implementation principle of a circular wire drawing auxiliary device for metal workpieces in the embodiment of the present application is as follows: when the metal workpiece is subjected to a wire drawing process, the workpiece is placed on the wire drawing disk 2, and the third gear 91 is rotated. The rotation of the third gear 91 drives the positioning member 8 to move along the sliding groove 21 and toward the workpiece until all the positioning members 8 are tightly pressed against the workpiece, so that the center of the workpiece is located on the rotation axis of the rotating rod 5, and the switch key 62 is turned on. The electromagnet 4 is electrically connected to the power supply, and the electromagnet 4 adsorbs the metal workpiece so that the workpiece is stably placed on the wire drawing disk 2, and the third gear 91 is rotated. The positioning member 8 moves toward the end of the sliding member away from the workpiece, thereby reducing the possibility that the positioning member 8 hinders the wire drawing operation of the metal workpiece, and the driving member 31 is started. The driving member 31 drives the wire drawing disk 2 to rotate, and the metal workpiece rotates with the wire drawing disk 2, and the sandpaper is pressed on the surface of the rotating metal workpiece, so that the metal surface is subjected to wire drawing, and the possibility of the metal workpiece moving on the wire drawing disk 2 causing the wire drawing line to be chaotic is reduced, thereby improving the wire drawing quality of the metal surface.

[0057] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
