Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention provides a welding wire drawing and shaping device through improvement, such as Figure 1-Figure 8 As shown, it includes an operating table 1, a molding mechanism 2 and a spraying mechanism 3. The outer wall of the operating table 1 is provided with a first boss 101, a second boss 102, a third boss 103 and a fourth boss 104 which are coaxial from top to bottom; a guide hole 115 is provided in the middle of the first boss 101, and the spraying mechanism 3 includes a rotating drum 301 movably arranged on the second boss 102, a limiting convex ring 302 is provided on the top of the rotating drum 301, a storage bin 305 is installed on the limiting convex ring 302, and an annular spray rack 306 located inside the rotating drum 301 is provided at the output end of the storage bin 305; When the drum 301 rotates, the spray rack 306 can spray lubricating powder on the outer surface of the welding wire to be drawn; the forming mechanism 2 includes a rotating part 203 movably mounted inside the third boss 103, and multiple groups of sub-mold sleeves 211 are movably mounted on the inner wall of the rotating part 203, and a contraction portion 212 is provided on the inner wall of the sub-mold sleeve 211. A symmetrical gear ring 219 is also movably mounted inside the rotating part 203, and multiple groups of extrusion portions 221 are provided on the inner wall of the gear ring 219; when the gear ring 219 rotates, the extrusion portion 221 extrude the sub-mold sleeve 211 and adjust the diameter of the welding wire after drawing.

[0022] In this embodiment: the welding wire drawing and shaping equipment is mainly divided into three parts: an operating table 1, a forming mechanism 2 and a spraying mechanism 3. When the equipment is in use, the welding wire reel 114 is first installed on the top of the operating table 1, and its rotating shaft is limited by the upper rotating seat 113 and the lower rotating seat 109, and then the welding wire is passed through the guide hole 115, the rotating drum 301, the sub-mold sleeve 211, the brush structure 123 and the guide wheel 122 in sequence. Then the spraying motor 307 and the rotating motor 207 are started. Driven by the spraying motor 307, since the outer wall of the belt 310 abuts against the rotating drum 301, the rotating drum 301 will drive the spray rack 306 to rotate freely, and the spray rack 306 will evenly spray lubricating powder on the surface of the welding wire. When the rotating member 203 rotates, it can be pulled while rotating, thereby further improving the forming efficiency.

When the gear ring 219 rotates clockwise, the extrusion portion 221 separates from the sub-mold sleeve 211, and the sub-mold sleeve 211 moves toward the outside of the rotating member 203 along the sliding groove 209 under the drive of the return spring 214, and the inner diameter of the molded sub-mold sleeve 211 increases.

[0023] See attached Figure 1 -Attached Figure 2 A lower rotating chamber 107 is provided on the top of the operating platform 1, in which a first bearing 108 is installed, and a lower rotating seat 109 is installed on the inner wall of the first bearing 108; a symmetrical lifting cylinder 110 is also installed on the top of the operating platform 1, and a top plate 124 is provided at the output end of the lifting cylinder 110, and an upper rotating chamber 111 is provided in the middle of the top plate 124, in which a second bearing 112 is installed, and an upper rotating seat 113 is installed on the inner wall of the second bearing 112, and a welding wire reel 114 is installed between the upper rotating seat 113 and the lower rotating seat 109.

In order to ensure that both ends of the welding wire drum 114 are movably arranged on the operating table 1 and can be quickly replaced, an upper rotating seat 113 and a lower rotating seat 109 that cooperate with each other are designed.

[0025] See attached Figure 1 -Attached Figure 2 A storage cavity 105 is provided inside the operating table 1 , and a control panel 106 is also provided on the outer wall of the operating table 1 .

[0026] In this embodiment, a storage chamber 105 is designed to store the welding wire reel 114 to be drawn. A control panel 106 is designed to control the operation of the device.

[0027] See attached Figure 1 -Attached Figure 2 and attached Figure 7 A spraying through hole 116 cooperating with the rotating drum 301 is opened at the center of the second boss 102, an outer notch 118 connected with the spraying through hole 116 is opened on the outer wall of the second boss 102, and an inner notch 303 cooperating with them is opened on the outer walls of the rotating drum 301 and the limiting convex ring 302.

[0028] In this embodiment, in order to facilitate the insertion of the welding wire to be drawn into the interior of the rotating drum 301 during operation, an outer notch 118 and an inner notch 303 structure that cooperate with each other are provided.

[0029] See attached Figure 2 and attached Figure 7 -Attached Figure 8 A mounting cavity 117 penetrating the spray through hole 116 is provided in the middle of the second boss 102, and limiting rollers 304 located on both sides of the outer notch 118 are movably installed inside the mounting cavity 117; a spray motor 307 is also installed on the top of the second boss 102, and an active roller 308 is installed at the output end of the spray motor 307, and a plurality of groups of driven rollers 309 are also installed inside the mounting cavity 117, and a belt 310 is arranged between the active roller 308 and the driven roller 309, and the outer wall of the belt 310 abuts against the rotating drum 301.

[0030] In this embodiment, driven by the spray motor 307, the active roller 308 and the driven roller 309 rotate in tandem, and since the outer wall of the belt 310 abuts against the rotating drum 301, the rotating drum 301 drives the spray rack 306 to rotate freely. The storage bin 305 stores lubricating powder inside, and a spray pump (not shown) is installed at the connection between the storage bin 305 and the spray rack 306.

[0031] See attached Figure 2 -Attached Figure 4 A forming through hole 119 cooperating with the rotating member 203 is provided in the middle of the third boss 103, a limiting ring groove 201 is provided on the inner wall of the forming through hole 119, a third bearing 202 is installed on the inner wall of the limiting ring groove 201, and a positioning convex ring 204 cooperating with the limiting ring groove 201 is provided on the outer wall of the rotating member 203; a driven gear 205 is provided on the top of the rotating member 203, a driving cavity 206 is provided on the top of the third boss 103, a rotating motor 207 is installed in the driving cavity 206, and a driving gear 208 meshing with the driven gear 205 is installed at the output end of the rotating motor 207.

[0032] In this embodiment, in order to improve the forming efficiency of the welding wire drawing, the rotating member 203 is movably installed inside the third boss 103. In order to drive the rotating member 203 to rotate automatically, a rotating motor 207 structure is designed. When the rotating member 203 rotates, it can draw and rotate at the same time, thereby further improving the forming efficiency.

[0033] See attached Figure 4 -Attached Figure 5 A plurality of sliding grooves 209 are provided on the inner wall of the rotating member 203, and symmetrical reset grooves 210 are provided on the upper and lower sides of the sliding grooves 209. A sliding arm 213 slidably arranged in the sliding grooves 209 is fixedly arranged on the outer wall of the sub-mold sleeve 211. A symmetrical reset spring 214 is also connected to the outer wall of the sub-mold sleeve 211, and the end of the reset spring 214 is connected to the inner wall of the reset groove 210.

[0034] In this embodiment, when the gear ring 219 rotates counterclockwise, the sub-mold sleeve 211 moves toward the middle of the rotating member 203 along the sliding groove 209 under the extrusion of the extrusion portion 221, and the inner diameter of the molded sub-mold sleeve 211 decreases. When the gear ring 219 rotates clockwise, the extrusion portion 221 separates from the sub-mold sleeve 211, and the sub-mold sleeve 211 moves toward the outside of the rotating member 203 along the sliding groove 209 under the drive of the return spring 214, and the inner diameter of the molded sub-mold sleeve 211 increases.

[0035] See attached Figure 4 -Attached Figure 6 A rotating bin 215 is provided inside the rotating member 203 and is located on the upper and lower sides of the sliding groove 209, and a gear ring 219 is movably installed in the rotating bin 215; symmetrical ring rails 216 are provided on the upper and lower inner walls of the rotating bin 215, and grooves 220 matching the gear ring 219 are provided on the upper and lower sides; a linkage cavity 217 connected to the rotating bin 215 is also provided inside the rotating member 203, and a dual-axis motor 218 is installed in the linkage cavity 217, and an extrusion gear 222 meshing with the gear ring 219 is installed at the output end of the dual-axis motor 218.

[0036] In this embodiment: In order to ensure that the ring gear 219 rotates freely relative to the rotating chamber 215, a ring rail 216 and a groove 220 structure that cooperate with each other are designed. In order to drive the ring gears 219 on the upper and lower sides to rotate synchronously, so as to further adjust the forming inner diameter of the sub-mold sleeve 211, a dual-axis motor 218 structure is designed. In the initial state, that is, when the sub-mold sleeve 211 abuts against the inner wall of the rotating member 203 and the forming inner diameter is the largest, the right-angle side of the extrusion part 221 abuts against the outer wall of the sub-mold sleeve 211. This design can further improve the stability of the sub-mold sleeve 211 during drawing.

[0037] See attached Figure 1 -Attached Figure 2A cleaning through hole 120 is opened in the middle of the fourth boss 104, and a brush structure 123 is detachably installed in the cleaning through hole 120; a support plate 121 is provided at the bottom of the fourth boss 104, and a guide wheel 122 is movably installed on the support plate 121.

[0038] In this embodiment, after the drawing is completed, a brush structure 123 is designed to clean the lubricating powder remaining on the surface of the welding wire. The end of the welding wire is connected to an external traction device, and a guide wheel 122 is designed to guide the welding wire.

[0039] Working principle of the present invention: When the device is used, firstly, the welding wire reel 114 is installed on the top of the operating table 1, and its rotating shaft is limited by the upper rotating seat 113 and the lower rotating seat 109, and then the welding wire is passed through the guide hole 115, the rotating drum 301, the sub-mold sleeve 211, the brush structure 123 and the guide wheel 122 in sequence. Then the spraying motor 307 and the rotating motor 207 are started. Driven by the spraying motor 307, since the outer wall of the belt 310 abuts against the rotating drum 301, the rotating drum 301 will drive the spray rack 306 to rotate freely, and the spray rack 306 will evenly spray lubricating powder on the surface of the welding wire. When the rotating member 203 rotates, it can be pulled and rotated at the same time, thereby further improving the forming efficiency. When the gear ring 219 rotates counterclockwise, under the extrusion of the extrusion part 221, the sub-mold sleeve 211 moves along the sliding groove 209 to the middle part of the rotating member 203, and the forming inner diameter of the sub-mold sleeve 211 is reduced. When the gear ring 219 rotates clockwise, the extrusion portion 221 separates from the sub-mold sleeve 211. At this time, driven by the return spring 214, the sub-mold sleeve 211 moves along the sliding groove 209 toward the outside of the rotating member 203, and the molding inner diameter of the sub-mold sleeve 211 becomes larger.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and inventive features disclosed herein.
