[0036] Referring to Figure 3 and Figure 4The drawing assembly comprises a drawing roller 16 made of alloy steel, the surface of which is specially treated and has a specific drawing pattern or structure for drawing on the surface of the aluminum plate, the inside of the drawing roller 16 is fixedly connected with an inner column 17 made of aluminum alloy, the inner column 17 provides installation space and support for linkage rods 18, conical blocks 20 and other components, and through cooperation with a linkage seat 26, the installation and fixation of the drawing roller 16 are realized, the inner column 17 is slidably connected at one end inside the linkage seat 26, which serves to position and support the inner column 17, the inner wall of the inner column 17 is slidably connected with the linkage rods 18, the linkage rods 18 are used to connect the buttons 19 and the conical blocks 20 to transfer the displacement force of the buttons 19, one end of the linkage rods 18 is fixedly connected with the buttons 19, the buttons 19 serve as an operation interface for the workers to trigger the subsequent unlocking action by pressing the buttons 19, the other end of the linkage rods 18 is fixedly connected with the conical blocks 20, the conical blocks 20 are metal conical columns, the conical blocks 20 serve to control the position of the locking rods 22 through their own displacement to realize the unlocking and locking of the drawing roller 16 and the linkage seat 26, the bottom of the conical blocks 20 is provided with a return spring 21, the function of the return spring 21 is to provide a restoring force after the displacement of the conical blocks 20 so that the conical blocks 20 can return to the initial position for next operation, one end of the return spring 21 is fixedly connected at the bottom of the conical blocks 20, the other end of the return spring 21 is fixedly connected inside the inner column 17, the outer wall of the conical blocks 20 is provided with a plurality of locking rods 22, which serve to be inserted into the inside of the linkage seat 26 under normal working conditions to realize the locking of the drawing roller 16 and the output end of the driving motor two 25, when the drawing roller 16 needs to be replaced, the inside of the inner column 17 is moved to retract to realize the unlocking of the drawing roller 16, the locking rods 22 are distributed in a circumferential manner, the bottom of the locking rods 22 is slidably connected inside the linkage seat 26, the outer wall of the locking rods 22 is fixedly connected with a limiting plate 24, the outer wall of the locking rods 22 is sleeved with a limiting spring 23, the function of the limiting spring 23 is to provide a restoring force to make the locking rods 22 slide inward and retract into the inside of the inner column 17 when the locking rods 22 lose the extrusion force of the conical blocks 20, one end of the limiting spring 23 is fixedly connected to the side wall of the limiting plate 24, the other end of the limiting spring 23 is fixedly connected inside the inner column 17;

[0037] Specifically, when there are different wire drawing operation requirements, the worker applies pressure to the button 19 in the direction of the inner column 17, and the button 19 moves linearly in the axial direction of the linkage rod 18 to the inside of the inner column 17. Since the linkage rod 18 is fixedly connected to the button 19 and the conical block 20 at both ends, when the button 19 moves, the linkage rod 18 also moves, thereby driving the conical block 20 to move. The displacement of the conical block 20 causes the reset spring 21 at the bottom of the conical block 20 to be gradually compressed, and the elastic potential energy is continuously increased. In the normal working state, the outer wall of the conical block 20 exerts lateral extrusion force on the locking rod 22, causing the locking rod 22 to move outward and insert into the containing groove 15, thereby achieving the locking of the wire drawing roller 16. When the conical block 20 moves inward, the contact position of the outer wall of the conical block 20 with the locking rod 22 changes, and the locking rod 22 is no longer subjected to lateral extrusion force, so that the limiting spring 23 on the outer wall of the locking rod 22 recovers and rebounds. The limiting spring 23 was in a compressed state due to the extrusion of the conical block 20 on the locking rod 22 before, and stored elastic potential energy. When the locking rod 22 loses the extrusion force, the limiting spring 23 releases the elastic potential energy, pushes the locking rod 22 away from the containing groove 15 through the limiting plate 24, and slides into the inner column 17. At this time, the worker can hold the wire drawing roller 16 with his hand and take it out of the linkage seat 26 at the output end of the driving motor 2, then the worker selects the wire drawing roller 16 that meets the new wire drawing operation requirements, aligns it with the linkage seat 26, and inserts the inner column 17 into the linkage seat 26. With the insertion of the inner column 17, the locking rod 22 is extruded by the outer wall of the conical block 20 and moves outward and inserts into the containing groove 15, thereby completing the installation and locking of the new wire drawing roller 16. In this way, different types of wire drawing rollers 16 can be quickly replaced, and different wire drawing requirements can be met.

[0038] Working principle: in the use of the aluminum plate wire drawing machine, first the staff will be placed in the bearing box 6 above the clamp 14 between aluminum plate. Subsequently by the console 4 start drive motor 8, drive motor 8 drive arm 9 rotation, the rotation of the rocker arm 9 drive its both ends of the connecting arm 10 also swing, the swing of the connecting arm 10 prompted its one end of the connecting table 11 in the guide rail 12 on the direction of the slide, the displacement of the connecting table 11 drive its top of the plurality of connecting column 13 displacement, in turn, drive the clamp 14 to the middle displacement, so that the aluminum plate both sides into the receiving slot 15 inside, so as to complete the fixation of aluminum plate, in turn, reaches the effect of quick fixing different size aluminum plate, after the fixation of aluminum plate, the staff through the console 4 control fixed box 5 inside the device drive motor 25 displacement, in turn, drive the wire drawing roller 16 displacement, at the same time, drive motor 25 also drive the wire drawing roller 16 rotation, so as to complete the wire drawing work on the surface of the aluminum plate, when there are different wire drawing operation needs, first the staff manually press button 19, the inward displacement of the button 19 through the linkage rod 18 drive the conical block 20 also inward displacement, the displacement of the conical block 20 makes its bottom of the return spring 21 force compression, the conical block 20 displacement, also makes the originally by its outer wall extrusion locking rod 22 lost the lateral extrusion force, so that the locking rod 22 outer wall of the limit spring 23 restore rebound, through the limiting plate 24 push the locking rod 22 end away from the linkage seat 26 inside, and slide into the inner column 17 inside, so that the staff can remove the wire drawing roller 16, and replace the new wire drawing roller 16, so as to reach the effect of quick replacement of different types of wire drawing roller 16, so as to compatible different wire drawing needs.
