Description

Technical Field

[0001] The present invention relates to the field of friction stir welding additive equipment, and in particular to an automatic wire feeding type friction stir welding additive feeding mechanism. Background Art

[0002] Friction stir welding (FSW) equipment is a new type of processing equipment that combines FSW technology with additive manufacturing principles. It is primarily used to achieve near-net-shape manufacturing of metal components through layer-by-layer material deposition. Its core principle is to utilize the thermal coupling effect of FSW to fuse raw materials such as welding wire and sheet metal with the substrate or deposited layers through plastic deformation, ultimately forming a metal part with a specific shape and properties. This technology combines the advantages of high joint strength, low heat input, and environmental friendliness.

[0003] The friction stir welding additive equipment also includes a feeding mechanism, which is used to transport materials such as welding wire into the friction stir welding head. However, in the feeding mechanism in the prior art, the wire release roller and the conveying roller structure are driven by two or more motors respectively, which causes the wire release speed and the conveying speed to be out of sync, which easily causes the welding wire to be entangled or blocked and accumulated inside the feeding mechanism, thereby affecting the wire feeding effect and wire feeding speed. Summary of the Invention

[0044] Working principle: When in use, first open the box door 101, then turn the bolt 216 to take it out from the inside of the rotating rod 202, and slide the wire-wound roller 203 to the outer wall of the rotating rod 202. When placing the wire-wound roller 203, the exposed end of the wire wound on the outer wall of the wire-wound roller 203 needs to face the left side, as shown in FIG. Figure 1 、 Figure 4 and Figure 5As shown, the exposed end of the welding wire is pulled downward, and then the cylinder 1 215 is started to move the connecting frame 209 to the left and drive the two rotating shafts 210, the conveying roller 211 and the gear 212 to move to the left, so that they are separated from the rotating shaft 1 205, the conveying roller 1 207 and the gear 1 208, and then the pulled-out welding wire portion is placed between the conveying roller 1 207 and the conveying roller 2 211, and then the cylinder 1 215 is started to move the connecting frame 209 to the right. During the movement, the rotating shaft 210 needs to be rotated to align the tooth groove of the gear 2 212 with the toothed portion of the gear 1 208. When the connecting frame 209 is moved into place, the gear 2 2 12 is meshed with gear 1 208, the outer wall of the conveying roller 211 fits with the outer wall of the conveying roller 1 207, and the welding wire is clamped between the conveying roller 1 207 and the conveying roller 2 211, and then the bolt 216 is threadedly connected to the inside of the rotating rod 202, and the surface of the bolt 216 fits with the surface of the wire-releasing roller 203, and the wire-releasing roller 203 is limited and fixed to the outer wall of the rotating rod 202. After the installation is completed, the motor 1 201 is started again, and the motor 1 201 is used to drive the rotating rod 202, the wire-releasing roller 203 and the driving wheel 204 to rotate, so that the welding wire moves downward continuously to achieve the effect of wire-releasing, and the driving wheel 204 rotates while driving the driven wheel 204. The wheel 206 rotates in the opposite direction, prompting the driven wheel 206 to drive one of the rotating shafts 1 205, the conveying roller 1 207 and the gear 1 208 to rotate, and the rotating shaft 1 205 rotates and drives the synchronous wheel 213 on its outer wall to rotate, thereby driving the synchronous belt 214 and the other rotating shaft 1 205 and the synchronous wheel 213 to rotate, thereby realizing the synchronous rotation of the two rotating shafts 1 205, the conveying roller 1 207 and the gear 1 208, and the rotation direction is opposite to that of the wire-releasing roller 203, and the gear 1 208 rotates while driving the gear 2 212 to rotate, thereby driving the rotating shaft 2 210 and the conveying roller 2 211 to rotate, thereby realizing the conveying roller 1 20 7 and the second conveying roller 211 rotate synchronously and in opposite directions, thereby continuously conveying the clamped welding wire portion downward, thereby achieving the effect of conveying the welding wire synchronously while the wire-releasing roller 203 releases the wire, and the driving wheel 204 and the driven wheel 206 are toothed wheels of the same model, size and number of teeth, so the wire-releasing speed is the same as the wire-conveyance speed, thereby solving the problem of different wire-releasing speeds and conveying speeds caused by two or more motors driving the wire-releasing roller 203, the conveying roller 1 207 and the conveying roller 2 211 respectively in the prior art, avoiding the problem of entanglement or blockage of the welding wire during the wire-releasing and conveying process, and improving the wire feeding efficiency;When the wire is fed, the motor 2 301 and the cylinder 2 308 can be started. The motor 2 301 drives the eccentric wheel 302 to rotate, and the rotation of the eccentric wheel 302 drives the connecting rod 303 to swing back and forth, thereby driving the installation box 304 and the sliding rod 305 on its lower surface to move back and forth. The sliding rod 305 is limited and slides inside the sleeve 306 and is supported by the spring 307. In the process of the installation box 304 moving up and down, when the installation box 304 moves up, the cylinder 2 308 pushes the sleeve 309 to make the splint 1 310 and the fan gear 1 311 rotate and open, and also drives the splint 2 312 and the fan gear 2 313 to rotate and open. When the installation box 304 moves up to the highest point, the cylinder 2 308 pulls the sleeve 309, prompting the sleeve 309 to pull the splint 1 310, thereby driving the splint 1 310 and the fan gear The first clamp 311 rotates an angle and causes the second clamp 312 and the second sector tooth 313 to rotate an angle, so that the first clamp 310 and the second clamp 312 close and clamp the outer wall of the welding wire. During the downward movement of the installation box 304, the first clamp 310 and the second clamp 312 always clamp the welding wire, thereby assisting the feeding of the welding wire. When the installation box 304 moves down to the lowest point, the second cylinder 308 pushes the shaft sleeve 309 to cause the first clamp 310 and the second clamp 312 to rotate open, no longer clamping the welding wire. The installation box 304 then moves up and down reciprocatingly, and the second cylinder 308 repeats the above operation, thereby assisting the wire feeding work and improving the wire feeding efficiency. After being fed, the welding wire passes through the bottom of the installation box 1 and simultaneously passes through the guide tube 4 into the interior of the friction stir welding head 5, and then the friction stir welding work is performed by the friction stir welding head 5.
