[0002] In the processing of metal parts for new energy vehicles, stamping equipment is used for stamping. The stamping equipment uses a mold to apply pressure to the metal sheet under the action of a press, causing it to undergo plastic deformation, thereby obtaining the required shape and size of the automotive parts.

[0003] However, in the current technology, the interior panels of new energy vehicles are mostly made of metal sheet stamping, such as stainless steel sheet, aluminum alloy sheet or magnesium aluminum alloy sheet. The existing stamping method is to first cut large interior panels into individual interior panels and then stamp them. The cutting equipment and stamping equipment are independent of each other. This single-piece processing method is time-consuming and labor-intensive, resulting in a long stamping cycle and low efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a CNC stamping equipment for processing metal interior panels for new energy vehicles. By integrating the cutting, stamping, and unloading of metal interior panels for new energy vehicles, the stamping effect is improved, aiming to solve the problems in the background technology.

[0007] As a preferred embodiment of the present invention, an elastic element is connected between the connecting block and the slider, and a stop is provided at the end of the slider.

[0008] As a preferred embodiment of the present invention, a cutter seat is fixedly connected to the fixed base, and a cutter that cooperates with the cutter seat is fixedly connected to the upper mold base for cutting the metal interior panel to be processed; and a spring seat is fixedly connected to the upper mold base, and a pressure seat is connected below the spring seat for pressing one end of the metal interior panel onto the cutter seat, and an elastic mechanism is connected between the pressure seat and the spring seat.

[0009] As a preferred embodiment of the present invention, the module is fixedly connected to both sides with positioning frames, the positioning frames are equipped with positioning wheels, and the fixed base is provided with clearance holes that cooperate with the positioning frames.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example: This example discloses a CNC stamping equipment for processing metal interior panels of new energy vehicles, suitable for stamping and forming metal interior panels, such as... Figures 1-6 As shown, this embodiment includes: a base 1, an upper mold base 4, a lower mold base 3, and a hydraulic cylinder 5 for driving the upper mold base 4 to rise and fall; a fixed arm 2 is fixedly connected to the base 1, and the hydraulic cylinder 5 is fixedly installed on the fixed arm 2; wherein, a fixed seat 31 is fixedly connected to the lower mold base 3, and a module 32 capable of rising and falling is connected to the upper surface of the fixed seat 31. The fixed seat 31 is provided with a receiving groove 318 that cooperates with the module 32, and a pressing block 41 that cooperates with the module 32 for stamping is fixedly connected to the upper mold base 4; during stamping, the metal interior panel is placed on the module 32, the hydraulic cylinder 5 drives the upper mold base 4 to fall, the pressing block 41 stamps the metal interior panel, drives the module 32 to fall into the receiving groove 318, and stamps the metal interior panel. After stamping, the upper mold base 4 rises, and the module 32 automatically pushes out the metal interior panel.

[0025] like Figures 3-4As shown, the fixed base 31 has a horizontally arranged slide groove 312 on its side, and a slider 313 is slidably connected in the slide groove 312. An inverted L-shaped pusher 311 is fixedly connected to the slider 313 for pushing out the stamped parts. The pusher 311 is located above the fixed base 31. An inclined ejector plate 6 is provided on one side of the fixed base 31. The pusher 311 pushes the formed metal interior panel onto the ejector plate 6. A slide rod 315 is fixedly connected to the slider 313, and a connecting block 314 is slidably connected to the slide rod 315. A bracket 47 is fixedly connected to the upper mold base 4, and a connecting rod 8 is hinged between the bracket 47 and the connecting block 314. An elastic element 316 is connected between the connecting block 314 and the slider 313. The elastic element 316 is a spring, which is sleeved on the surface of the slide rod 315. A stop 317 is provided at the end of the slide rod 315. When the upper mold base 4 descends, it drives the slider. 313 and connecting block 314 slide to the left along slide groove 312 simultaneously. When slider 313 slides to the leftmost position, pressure block 41 just contacts module 32. When upper mold base 4 continues to descend to stamp the metal interior panel, it drives connecting block 314 to continue sliding to the left, compressing elastic element 316, thus not affecting the descent of upper mold base 4. When the metal interior panel is stamped and upper mold base 4 rises, elastic element 316 releases its elastic force, pushing connecting block 314 to slide to the right, and then drives slider 313 to move together, driving pusher 311 to move to the right. Since the metal interior panel is irregularly shaped after stamping and the height increases, pusher 311 can push the stamped metal interior panel onto discharge plate 6 when it moves, and finally discharge from discharge plate 6, thereby achieving the purpose of automatically pushing out the stamped metal interior panel.

[0026] Preferably, a guide rod 319 is fixedly connected inside the receiving groove 318. The guide rod 319 is movably connected to the module 32. A compression spring 320 is connected to the surface of the guide rod 319. The compression spring 320 plays the role of lifting and resetting the module 32, automatically pushing the module 32 out of the receiving groove 318. A positioning plate 37 is fixedly connected to the fixed seat 31 for positioning the end of the metal interior panel. The height of the positioning plate 37 is higher than the height of the module 32. By blocking and positioning one end of the metal interior panel through the positioning plate 37, the feeding distance of the metal interior panel is the same each time, ensuring the accuracy of the cutting and stamping position of the metal interior panel.

[0027] like Figure 6As shown, a cutter seat 36 is fixedly connected to the fixed base 31. The surface of the cutter seat 36 is flush with the surface of the module 32. The cutter seat 36 and the positioning plate 37 are respectively located on both sides of the fixed base 31 and on both sides of the module 32. A cutter 45 that cooperates with the cutter seat 36 is fixedly connected to the upper mold base 4 for cutting the metal interior panel to be processed. A spring seat 42 is fixedly connected to the upper mold base 4. A pressure seat 43 is connected below the spring seat 42 for pressing one end of the metal interior panel onto the cutter seat 36. The pressure seat 43 and the spring seat 42 are connected to each other. An elastic mechanism 44 is connected between the spring seats 42. The elastic mechanism 44 adopts a structure combining a slide rod and a spring. When the upper mold seat 4 descends, the pressure seat 43 first presses and fixes the metal interior panel. As the upper mold seat 4 descends, the cutter 45 cuts the metal interior panel. When cutting, the side of the cutter 45 contacts the side of the cutter seat 36, and the fixed seat 31 is provided with a clearance groove that cooperates with the cutter 45. After the metal interior panel is cut, the upper mold seat 4 continues to descend, the pressure block 41 stamps the metal interior panel, and the cutter 45 descends into the clearance groove.

[0028] Preferably, positioning frames 33 are fixedly connected to both sides of module 32. Positioning wheels 34 are installed on the positioning frames 33, and the positioning frames 33 are provided with strip holes that cooperate with the positioning wheels 34 to facilitate the adjustment of the position of the positioning wheels 34. The fixed base 31 is provided with clearance holes 35 that cooperate with the positioning frames 33 to facilitate the lifting and lowering of the positioning frames 33. The positioning wheels 34 position the two sides of the metal interior panel, and the positioning plate 37 positions the end of the metal interior panel, thereby limiting the position of the metal interior panel.

[0029] Preferably, a positioning rod 38 is fixedly connected to the lower mold base 3, a sleeve 39 is movably connected to the positioning rod 38, and a cylindrical spring 310 is connected to the surface of the positioning rod 38. The cylindrical spring 310 is located between the sleeve 39 and the lower mold base 3. A pressure cylinder 46 that cooperates with the positioning rod 38 is fixedly connected to the upper mold base 4. When the upper mold base 4 descends, the pressure cylinder 46 is inserted into the positioning rod 38, which drives the sleeve 39 to descend and compresses the cylindrical spring 310.

[0030] Preferably, multiple U-shaped support frames 7 are fixedly connected to the base 1, and a pair of limiting wheels 71 are connected to the support frames 7 to ensure that the position of the metal interior panel will not shift during the feeding process.

[0031] Working principle: The metal interior panel is fed into the container manually or mechanically. One end of the metal interior panel abuts against the positioning plate 37. The upper mold base 4 is lowered by the hydraulic cylinder 5. The pressure base 43 first presses and fixes the metal interior panel. The metal interior panel is cut by the cutter 45. Then the pressure block 41 stamps the metal interior panel into shape. Then the upper mold base 4 starts to rise. The module 32 pushes out the formed metal interior panel. As the upper mold base 4 rises, it drives the pusher 311 to slide to the right, pushing the formed metal interior panel onto the discharge plate 6. The panel is discharged from the discharge plate 6, thus completing the integrated feeding, cutting, stamping and discharge of the metal interior panel, effectively improving the stamping efficiency.

[0032] Finally, it should be noted that in the description of this invention, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
