[0021] Reference Figure 1-Figure 3 , a magnesium alloy wire electroplastic continuous drawing device, comprising a wire-releasing support 1 and a wire-collecting support 2, wherein a pretreatment mechanism and a wire-drawing mechanism are respectively provided between the wire-releasing support 1 and the wire-collecting support 2;

[0022] The pretreatment mechanism is located at the front end of the wire drawing mechanism;

[0023] The pretreatment mechanism includes a pickling box 3, which realizes the action of cleaning the oxide layer of the wire by the pickling box 3;

[0024] The wire drawing mechanism includes a wire drawing block 4 , and the wire drawing mechanism enables the wire drawing block 4 to draw the wire material.

[0025] The pretreatment mechanism also includes a heating box 301, which is located at the rear end of the pickling box 3. The inner wall of the heating box 301 is fixedly connected to an electric heating tube 302, and the surface of the heating box 301 is fixedly connected to a temperature sensor 303. The two temperature sensors 303 are symmetrically distributed with the axis of the heating box 301 as the center.

[0026] Furthermore, the heating box 301 heats the magnesium alloy wire, and the temperature sensors 303 at both ends of the heating box 301 monitor the temperatures at the inlet and outlet of the heating box 301 .

[0027] A fixed shaft 304 is fixedly connected to the inner wall of the pickling box 3, and a pickling wheel 305 is rotatably connected to the surface of the fixed shaft 304. Guide brackets 306 are provided on both sides of the pickling box 3. The two guide brackets 306 are symmetrically distributed with the axis of the pickling box 3 as the center, and the surface of the guide brackets 306 is rotatably connected to the guide wheel 307.

[0028] Furthermore, the magnesium alloy wire passes through the surface of the guide wheel 307 on one side, bypasses the pickling wheel 305 and then passes through the surface of the guide wheel 307 on the other side. Pickling liquid is added to the pickling box 3.

[0029] The wire drawing mechanism further includes a lubrication box 401 , which is located at the rear end of the heating box 301 . A feed port 402 is provided above the lubrication box 401 , a clearing port 403 is provided below the lubrication box 401 , and an observation window 404 is provided on the surface of the lubrication box 401 .

[0030] Furthermore, the wire is lubricated during the drawing process, and the observation window 404 is convenient for observing the remaining lubricant and adding it in time.

[0031] The wire drawing block 4 is located at the rear end of the lubrication box 401 . A reducing hole 405 and a pressure relief hole 406 are respectively opened on the surface of the wire drawing block 4 . The inner wall of the reducing hole 405 is fixedly connected to the inner wall of the pressure relief hole 406 .

[0032] Furthermore, the lubricated magnesium alloy wire passes through the reducing hole 405 and exits from the pressure relief hole 406 to complete the drawing.

[0033] The surface of the wire-releasing bracket 1 and the surface of the wire-collecting bracket 2 are respectively fixedly connected with the wire-releasing motor 407 and the wire-collecting motor 408. The output shaft of the wire-releasing motor 407 and the output shaft of the wire-collecting motor 408 are respectively fixedly connected with the wire-releasing roller 409 and the wire-collecting roller 410 through a coupling. The surface of the wire-releasing roller 409 and the surface of the wire-collecting roller 410 are respectively rotatably connected with the surface of the wire-releasing bracket 1 and the surface of the wire-collecting bracket 2.

[0034] Furthermore, by cooperating with the unwinding roller 409 and the collecting roller 410 , the feeding speed of the magnesium alloy wire can be kept balanced and adjustable, thereby avoiding material accumulation at the drawing mechanism due to excessive speed or excessive slow speed or wire breakage due to excessive traction.

[0035] By setting up a pretreatment mechanism and a wire drawing mechanism, the magnesium alloy wire is first pickled to pretreat the oxide layer on the surface, and then heated by the induction current of the electric heating mechanism to improve the plastic deformation ability of the magnesium alloy wire. During the drawing process, lubricant is added to reduce the friction between the material and the mold, protect the mold and improve product quality, which solves the technical problem that the existing drawing device does not treat the oxide layer on the surface of the magnesium alloy wire and add lubricant during the drawing process.

[0036] Working principle:

[0037] Before use, the magnesium alloy wire is clamped on the wire-releasing roller 409 on the surface of the wire-releasing bracket 1. The wire-releasing motor 407 on the surface of the wire-releasing bracket 1 drives the wire-releasing roller 409 to rotate and slowly releases the wire. The magnesium alloy wire passes through the guide wheel 307 on one side of the pickling box 3 and enters the pickling box 3. After bypassing the pickling wheel 305, it passes through the pickling box 3 and goes out from the guide wheel 307 on the other side. The magnesium alloy wire under the pickling wheel 305 is immersed in the pickling solution to remove the surface oxide layer. The magnesium alloy wire after surface pretreatment passes through the heating box 301. The electric heating tube 302 inside the heating box 301 quickly heats the magnesium alloy wire and keeps the temperature constant. The temperature sensors 303 on both sides of the heating box 301 monitor the temperature of the magnesium alloy wire at the inlet and outlet of the heating box 301. The heated magnesium alloy wire passes through the lubrication box 401. The internal filling of the lubrication box 401 The lubricant is filled with lubricant, and the observation window 404 on the surface of the lubrication box 401 is used to observe the remaining lubricant in the lubrication box 401 and add it in time from the feed port 402 above the lubrication box 401. The cleaning port 403 below the lubrication box 401 is convenient for cleaning and replacing the lubricant. The lubricated magnesium alloy wire passes through the reducing hole 405 on one side of the wire drawing block 4 and passes out from the pressure relief hole 406 on the other side of the wire drawing block 4 to complete the drawing of the magnesium alloy wire. The drawn magnesium alloy wire is clamped on the wire-receiving roller 410, and the wire-receiving motor 408 on the surface of the wire-receiving bracket 2 drives the wire-receiving roller 410 to rotate and slowly rewind the wire. Through the mutual cooperation of the wire-releasing roller 409 and the wire-receiving roller 410, the feeding speed of the magnesium alloy wire can be guaranteed to be balanced and adjustable, thereby avoiding material accumulation at the drawing mechanism due to too fast or too slow speed or wire breakage due to excessive traction.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
