Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing, and specifically, it is a wire drawing and shaping device and its wire drawing and shaping process for welding wires. Background Art

[0002] The metal wire drawing process is a metal processing method. By applying a tensile force to the metal using a wire drawing die, the metal is made to pass through the die hole and gradually become thinner to achieve the required specifications and dimensions. This process is widely used in the industrial field and can produce metal wires of various different specifications and materials, such as copper wires, steel wires, nickel wires, etc. The basic principle of the metal wire drawing process is to apply a tensile force to the steel wire through a wire drawing die, making it pass through the die hole and gradually become thinner to achieve the required specifications and dimensions. When the metal wire is being drawn, under the action of pulling, the metal wire sequentially passes through multiple die holes, causing its diameter to gradually become smaller to the required size.

[0003] A patent application with the publication number CN118080591A discloses a metal wire drawing device, which relates to the technical field of wire drawing equipment. It includes a U-shaped frame and a base fixedly connected to the bottom of the U-shaped frame. A wire placing and winding mechanism is installed at the top of the U-shaped frame, and the wire placing and winding mechanism winds a metal raw wire. Two optical axes are installed in the middle cavity of the mounting plate, and two powder coating components are slid together by the two optical axes. The two powder coating components jointly and elastically clamp the free end of the metal raw wire. A vibration powder adding component is installed at the top of each powder coating component. A powder bin is fixedly installed at the top of the U-shaped frame. A hose is connected to the top of each vibration powder adding component, and each hose is connected to the bottom of the powder bin. An installation frame is fixedly installed in the middle of the U-shaped frame, and a wire drawing die sleeve is spirally installed on the installation frame. This metal wire drawing device uses lubricating powder to lubricate the metal raw wire passing through the wire drawing die sleeve, reducing the probability of metal raw wire breakage and improving the yield rate.

[0004] However, the processing efficiency of the above-disclosed metal wire drawing device is generally average. The powder coating components are prone to dead corners during operation, and cannot spray lubricating powder on the metal wire to be drawn in a 360-degree manner. Moreover, the degree of freedom and the applicable range are relatively poor, and the diameter of the die sleeve cannot be adaptively adjusted according to actual needs, lacking a variable-diameter wire drawing die sleeve structure.

[0032] The following will combine the attached Figures 1 to 8 The technical solutions of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides a wire drawing and shaping device by improvement. As Figures 1 - 8 shown, it includes an operating table 1, a forming mechanism 2 and a spraying mechanism 3. Coaxial first boss 101, second boss 102, third boss 103 and fourth boss 104 are sequentially arranged on the outer wall of the operating table 1 from top to bottom; a diversion hole 115 is arranged in the middle of the first boss 101. The spraying mechanism 3 includes a rotating cylinder 301 movably arranged on the second boss 102. A limiting convex ring 302 is arranged at the top of the rotating cylinder 301, and a storage bin 305 is installed on the limiting convex ring 302. The output end of the storage bin 305 is provided with an annular spraying rack 306 located inside the rotating cylinder 301; when the rotating cylinder 301 rotates, the spraying rack 306 can spray lubricating powder on the outer surface of the wire to be drawn. The forming mechanism 2 includes a rotating part 203 movably installed inside the third boss 103. Multiple groups of sub-mold sleeves 211 are movably installed on the inner wall of the rotating part 203. A shrinking part 212 is arranged on the inner wall of the sub-mold sleeve 211. Symmetric ring gears 219 are also movably installed inside the rotating part 203. Multiple groups of extrusion parts 221 are arranged on the inner wall of the ring gear 219; when the ring gear 219 rotates, the extrusion parts 221 extrude the sub-mold sleeve 211 and adjust the diameter of the wire after drawing.

[0034] In this embodiment: The wire drawing and shaping device is mainly divided into three parts: an operation table 1, a shaping mechanism 2, and a spraying mechanism 3. When the device is in use, first, the wire reel 114 is installed on the top of the operation table 1, and its rotating shaft is limited by the upper rotating seat 113 and the lower rotating seat 109. Then, the wire passes through the diversion hole 115, the rotating cylinder 301, the sub-die 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 cylinder 301, the rotating cylinder 301 will drive the spraying frame 306 to rotate freely. At this time, the spraying frame 306 will evenly spray lubricating powder on the surface of the wire. When the rotating part 203 rotates, it can be drawn and rotated at the same time, thereby further improving the shaping efficiency. When the gear ring 219 rotates counterclockwise, under the extrusion of the extrusion part 221, the sub-die sleeve 211 moves along the sliding groove 209 towards the middle of the rotating part 203. At this time, the forming inner diameter of the sub-die sleeve 211 decreases. When the gear ring 219 rotates clockwise, the extrusion part 221 disengages from the sub-die sleeve 211. At this time, driven by the return spring 214, the sub-die sleeve 211 moves along the sliding groove 209 towards the outside of the rotating part 203. At this time, the forming inner diameter of the sub-die sleeve 211 becomes larger.

[0035] Refer to the appendix Figure 1 - Appendix Figure 2 , a lower rotating cavity 107 is opened on the top of the operation table 1. A first bearing 108 is installed in the lower rotating cavity 107, and a lower rotating seat 109 is installed on the inner wall of the first bearing 108; symmetric lifting cylinders 110 are also installed on the top of the operation table 1. The output end of the lifting cylinder 110 is provided with a top plate 124. An upper rotating cavity 111 is opened in the middle of the top plate 124. A second bearing 112 is installed in the upper rotating cavity 111, and an upper rotating seat 113 is installed on the inner wall of the second bearing 112. A wire reel 114 is installed between the upper rotating seat 113 and the lower rotating seat 109.

[0036] In this embodiment: During operation, the wire wound on the wire reel 114 passes through the first boss 101, the second boss 102, the third boss 103, and the fourth boss 104 in sequence. In order to ensure that both ends of the wire reel 114 are movably arranged on the operation table 1 and can be quickly replaced, the mutually cooperating upper rotating seat 113 and lower rotating seat 109 are designed.

[0037] Refer to the appendix Figure 1 - Appendix Figure 2 , a storage cavity 105 is arranged inside the operation table 1, and a control panel 106 is also arranged on the outer wall of the operation table 1.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] In this embodiment, in order to improve the forming efficiency of 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, the structure of the rotating motor 207 is designed. When the rotating member 203 rotates, it can rotate while drawing, thereby further improving the forming efficiency.

[0045] Refer to the appendix Figure 4 - appendix Figure 5 On the inner wall of the rotating member 203, a plurality of sliding grooves 209 are formed. Symmetric reset grooves 210 are formed on the upper and lower sides of the sliding grooves 209. On the outer wall of the sub-mold sleeve 211, a sliding arm 213 slidably disposed in the sliding groove 209 is fixedly provided. On the outer wall of the sub-mold sleeve 211, symmetric reset springs 214 are further connected. The end of the reset spring 214 is connected to the inner wall of the reset groove 210.

[0046] In this embodiment, when the gear ring 219 rotates counterclockwise, under the extrusion of the extrusion portion 221, the sub-mold sleeve 211 moves along the sliding groove 209 towards the middle of the rotating member 203. At this time, the forming inner diameter of the sub-mold sleeve 211 decreases. When the gear ring 219 rotates clockwise, the extrusion portion 221 disengages from the sub-mold sleeve 211. At this time, under the drive of the reset spring 214, the sub-mold sleeve 211 moves along the sliding groove 209 towards the outside of the rotating member 203. At this time, the forming inner diameter of the sub-mold sleeve 211 increases.

[0047] Refer to the appendix Figure 4 - appendix Figure 6 Inside the rotating member 203, rotating chambers 215 are formed on the upper and lower sides of the sliding grooves 209. The gear ring 219 is movably installed in the rotating chambers 215; on the upper and lower inner walls of the rotating chambers 215, symmetric ring tracks 216 are provided; on the upper and lower sides of the gear ring 219, grooves 220 cooperating with the ring tracks 216 are formed; inside the rotating member 203, a linkage cavity 217 communicating with the rotating chambers 215 is further formed. A double-shaft motor 218 is installed in the linkage cavity 217. An extrusion gear 222 meshing with the gear ring 219 is installed at the output end of the double-shaft motor 218.

[0048] In this embodiment, in order to ensure the free rotation of the gear ring 219 relative to the rotating chambers 215, the structure of the mutually cooperating ring tracks 216 and grooves 220 is designed. In order to drive the gear rings 219 on the upper and lower sides to rotate synchronously, thereby further adjusting the forming inner diameter of the sub-mold sleeve 211, the structure of the double-shaft motor 218 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, at this time, the right-angle side of the extrusion portion 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.

[0049] Refer to the appendix Figure 1 - appendix Figure 2, a cleaning through-hole 120 is provided 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.

[0050] In this embodiment: After the drawing is completed, in order to wipe the lubricating powder remaining on the surface of the welding wire clean, the brush structure 123 is designed. The end of the welding wire is connected to an external traction device, and the guide wheel 122 structure is designed to guide the welding wire.

[0051] The working principle of the present invention: When the device is in use, first, 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. Then, the welding wire passes through the diversion hole 115, the rotating cylinder 301, the sub-die 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 cylinder 301, the rotating cylinder 301 will drive the spraying frame 306 to rotate freely. At this time, the spraying frame 306 will evenly spray lubricating powder on the surface of the welding wire. When the rotating part 203 rotates, it can be drawn 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-die sleeve 211 moves towards the middle of the rotating part 203 along the sliding groove 209. At this time, the forming inner diameter of the sub-die sleeve 211 decreases. When the gear ring 219 rotates clockwise, the extrusion part 221 disengages from the sub-die sleeve 211. At this time, driven by the return spring 214, the sub-die sleeve 211 moves towards the outside of the rotating part 203 along the sliding groove 209. At this time, the forming inner diameter of the sub-die sleeve 211 becomes larger.
