[0033] In this embodiment: the integrated punching and welding machine for automobile parts is mainly divided into three parts: an operating table 1, a punching mechanism 2 and a welding mechanism 3. When the device is working, the semi-finished steel plate is first placed on the top of the punching cavity 213, and then the hydraulic cylinder 222 is started to punch it. The parts after punching are automatically ejected under the action of the moving plate 215 and the return spring 216, and then the control panel 224 is used to start multiple groups of welding mechanisms 3 to weld the gaps at the four diagonal positions from bottom to top. When the welding is completed, the four groups of welding mechanisms 3 continue to move upward along the vertical tooth plate 241 to avoid interference with the punching bottom plate 209 when it is turned over. Then start the first cylinder 205 and close the second cylinder 206, at this time, the limit plate 1 207 will be inserted into the slot 1 212, and the limit plate 2 208 will be separated from the slot 2 219. Then start the lifting motor 238, and when the rotating wheel 239 rotates, the protrusion 240 will squeeze the guide wheel 236. At this time, the stamping bottom plate 209 turns to the left, and the debris remaining on its surface will fall into the debris bin 102. When the protrusion 240 is separated from the guide wheel 236, the lifting structure 228 returns to its original position. Then the first cylinder 205 is closed and the second cylinder 206 is started. At this time, the limit plate 1 207 will be separated from the slot 1 212, and the limit plate 2 208 will be inserted into the slot 2 219. Then the rotating wheel 239 continues to rotate, and the protrusion 240 will squeeze the guide wheel 236. At this time, the stamping bottom plate 209 turns to the right, and the parts on the moving plate 215 will fall into the finished product box 103 through the blanking notch 220.

[0034] See attached Figure 6 -Attached Figure 7 A stamping cavity 213 is provided in the middle of the stamping bottom plate 209 , a boss 214 is provided at the bottom of the stamping cavity 213 , a moving plate 215 is movably provided in the stamping cavity 213 , and the bottom of the moving plate 215 is connected to the bottom of the stamping cavity 213 through multiple sets of return springs 216 .

[0035] In this embodiment, after the stamping is completed, in order to make the parts pop out automatically, a plurality of sets of return springs 216 are designed at the bottom of the moving plate 215 .

[0036] See attached Figure 1 and attached Figure 3 A support frame 221 is provided in the middle of the stamping bottom plate 209 , a hydraulic cylinder 222 is installed on the top of the support frame 221 , and a stamping head 223 cooperating with the stamping cavity 213 is connected to the output end of the hydraulic cylinder 222 .

[0037] In this embodiment, in order to punch the semi-finished product, a punch head 223 cooperating with the punching cavity 213 is connected to the output end of the hydraulic cylinder 222 .

[0038] See attached Figure 3 -Attached Figure 5The lifting structure 228 includes a top rod 229 movably arranged on a slide seat 227, an arc-shaped rail 231 is arranged at the bottom of the top rod 229, a T-shaped slot 232 is opened in the arc-shaped rail 231, the T-shaped slot 232 runs through both sides of the arc-shaped rail 231, and symmetrical T-shaped sliders 233 are movably installed in the T-shaped slot 232, a screw rod 234 is fixedly connected to the back of the T-shaped slider 233, and a nut 235 is threadedly connected to the screw rod 234; a guide wheel 236 is movably arranged on the other side of the T-shaped slider 233.

[0039] In this embodiment, the position of the guide wheel 236 relative to the arc track 231 can be freely adjusted according to actual needs through the cooperation of the T-slot 232 and the T-slider 233. When the rotating wheel 239 rotates, when the protrusion 240 contacts the first guide wheel 236, the push rod 229 rises upward. When the protrusion 240 is separated from the last guide wheel 236, the push rod 229 will fall. Therefore, by adjusting the position of the T-slider 233 in the arc track 231, the lifting time can be further adjusted, thereby further adjusting the chip removal and material unloading time.

[0040] See attached Figure 3 -Attached Figure 5 A symmetrical baffle 230 is provided on the outer wall of the top rod 229.

[0041] In this embodiment: in a natural state, when the protrusion 240 does not press the guide wheel 236 upward, in order to prevent the lifting structure 228 from sliding off the slide seat 227, a baffle 230 is designed on its outer wall.

[0042] See attached Figure 3 -Attached Figure 5 A rotating groove 237 is provided in the middle of the cross frame 225, and a lifting motor 238 is installed on the other side of the cross frame 225. The output end of the lifting motor 238 is provided with a rotating wheel 239 rotatably arranged in the rotating groove 237, and the rotating wheel 239 is provided with a protrusion 240 that cooperates with the guide wheel 236.

[0043] In this embodiment, in the non-working state, the push rod 229 abuts against the upper stamping bottom plate 209. When the lifting motor 238 drives the rotating wheel 239 to rotate, the protrusion 240 will lift the guide wheel 236 upward, thereby driving the push rod 229 to flip the stamping bottom plate 209, and finally realize chip removal and material unloading.

[0044] See attached Figure 8 -Attached Fig.10The welding mechanism 3 includes a traveling frame 301, a traveling motor 302 is installed on the side of the traveling frame 301, and the output end of the traveling motor 302 is connected to a traveling gear 303 meshing with the vertical tooth plate 241, and a rotating seat 304 is also installed at the bottom of the traveling frame 301, and a telescopic upper arm 305 is arranged at the bottom of the rotating seat 304, and a telescopic lower arm 306 is slidably arranged in the telescopic upper arm 305; a telescopic cavity 307 is provided on the side of the telescopic lower arm 306, and a telescopic tooth plate 308 is installed at the bottom of the telescopic cavity 307; an adjusting cavity 309 connected to the telescopic cavity 307 is provided on the side of the telescopic upper arm 305; an adjusting plug 310 is rotatably arranged in the adjusting cavity 309, and a telescopic gear 311 meshing with the telescopic tooth plate 308 is arranged at the bottom of the adjusting plug 310; a plurality of groups of balls 312 are movably arranged on the inner wall of the adjusting cavity 309, and a plurality of groups of positioning grooves 313 cooperating with the adjusting plug 310 are arranged on the outer wall of the adjusting plug 310.

[0045] In this embodiment: In order to automatically drive the welding mechanism 3 to move up and down relative to the vertical tooth plate 241, a traveling gear 303 is designed to mesh with it. In order to rotate the welding gun 315, thereby further improving the degree of freedom, a rotating seat 304 is installed at the bottom of the traveling frame 301. In order to freely adjust the extension and contraction of the welding gun 315 according to actual work requirements, a telescopic gear 311 and a telescopic tooth plate 308 that cooperate with each other are designed. In order to further improve the stability of the regulating plug 310 during operation, a ball 312 and a positioning groove 313 that cooperate with each other are designed.

[0046] See attached Figure 8 -Attached Fig.10 The bottom of the telescopic lower arm 306 is movably connected to a welding gun 315 through a symmetrical connecting arm 314. A swing bin 316 is provided at the bottom of the telescopic lower arm 306. A swing motor 317 is installed in the swing bin 316. A swing arm 318 is installed on the output end of the swing motor 317. A driving rod 320 is connected to the swing arm 318. A swing groove 319 cooperating with the driving rod 320 is provided at the bottom of the welding gun 315.

[0047] In this embodiment, in order to adjust the angle and position of the welding gun 315, the welding gun 315 is swingably arranged at the bottom of the telescopic lower arm 306 through the connecting arms 314 on both sides. In order to automatically drive the welding gun 315 to swing so as to adjust the angle, a driving rod 320 and a swinging slot 319 that cooperate with each other are designed.

[0048] See attached Figure 1 and attached Figure 4 A rotating groove 204 is provided on the rotating seat 1 202 and the rotating seat 2 203 , and a control panel 224 is installed on the side of the supporting frame 221 .

[0049] In this embodiment, in order to improve the stability during deflection, a rotation groove 204 cooperating with the rotation shaft 1 211 is provided on the rotation seat 1 202, and a rotation groove 204 cooperating with the rotation shaft 218 is also provided on the rotation seat 203. In order to control the operation of the device, a control panel 224 is installed on the side of the support frame 221.

[0050] See attached Figure 6 A blanking notch 220 is provided on one side of the punching cavity 213 close to the second rotating seat 203 .

[0051] In this embodiment, since the automobile parts themselves have a certain weight, after the punching and welding is completed, under the gravity pressure of the box body, the height of the moving plate 215 will be slightly lower than the punching cavity 213. When the punching bottom plate 209 deflects to the left, this design can prevent the parts from accidentally sliding off when dumping the debris. When the punching bottom plate 209 deflects to the right, in order to ensure that the parts slide off smoothly and leave the punching cavity 213, a material discharge notch 220 structure is designed.

[0052] Working principle of the present invention: When the device is working, the semi-finished steel plate is first placed on the top of the stamping cavity 213, and then the hydraulic cylinder 222 is started to stamp it. The stamped parts are automatically ejected under the action of the moving plate 215 and the return spring 216, and then the control panel 224 is used to start the multiple welding mechanisms 3 to weld the gaps at the four diagonal positions from bottom to top. When the welding is completed, the four welding mechanisms 3 continue to move upward along the vertical tooth plate 241 to avoid interference with the stamping bottom plate 209 when it is turned over. Then the first cylinder 205 is started and the second cylinder 206 is closed. At this time, the limit plate 1 207 will be inserted into the slot 1 212, and the limit plate 2 208 will be separated from the slot 2 219. Then the lifting motor 238 is started, and when the rotating wheel 239 rotates, the protrusion 240 will squeeze the guide wheel 236. At this time, the stamping bottom plate 209 turns to the left, and the debris remaining on its surface will fall into the debris bin 102. When the protrusion 240 is separated from the guide wheel 236, the lifting structure 228 returns to its original position. Then the first cylinder 205 is closed and the second cylinder 206 is started. At this time, the limit plate 1 207 is separated from the slot 1 212, and the limit plate 208 is inserted into the slot 2 219. Then the rotating wheel 239 continues to rotate, and the protrusion 240 presses the guide wheel 236. At this time, the stamping bottom plate 209 turns right, and the parts on the moving plate 215 fall into the finished product box 103 through the blanking notch 220.

[0053] The present invention can punch semi-finished steel plates through the cooperation of the punching cavity 213 and the punching head 223. The box body after punching rises upward under the action of the reset spring 216. At this time, the four diagonal parts of the iron box can be welded by the welding gun 315. After welding, driven by the lifting motor 238, the protrusion 240 on the rotating wheel 239 will lift the lifting structure 228 upward. Since the iron box itself has a certain weight, the top of the moving plate 215 will be slightly lower than the punching cavity 213 after the punching is completed. At this time, under the obstruction of the inner wall of the punching cavity 213, the auto part will not slide down during chip removal. Then the rotating wheel 239 continues to rotate, and the punching bottom plate 209 will return to its original position. Then the second cylinder 206 is opened and the first cylinder 205 is closed. At this time, the auto part will fall into the finished product box 103 on the right through the blanking notch 220. This design further improves the processing efficiency and practicality of the punching and welding machine for auto parts.

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.
