Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more specifically to a sheet metal electroplating system and process for new energy vehicles. Background Technology

[0002] Automotive sheet metal typically refers to the metal components of a car body, including the body shell, doors, hood, trunk lid, roof, and other parts. These components are usually made of sheet metal, which is processed from sheet metal through cutting, stamping, bending, welding, and other processes. Sheet metal parts in new energy vehicles often use lightweight materials such as aluminum alloys, high-strength steel, and magnesium alloys to reduce the overall weight of the vehicle. Special pretreatment is required before electroplating aluminum alloys, typically using chemical or mechanical methods to remove the oxide layer from the surface. Currently, sheet metal electroplating systems cannot remove the oxide layer from the aluminum alloy surface before electroplating. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a new energy vehicle sheet metal electroplating system, which has the advantage of facilitating the removal of the oxide layer on the surface of rod-shaped aluminum alloy sheet metal parts.

[0004] A new energy vehicle sheet metal electroplating system includes a mold holder, a lower mold, a hydraulic cylinder, and an upper mold. The lower mold is welded to the mold holder, the hydraulic cylinder is screwed to the top of the lower mold, and the upper mold is screwed to the other end of the hydraulic cylinder. Abrasive grains are provided above the lower mold and below the upper mold.

[0005] A process for a sheet metal electroplating system for new energy vehicles includes the following steps:

[0006] S1: Place the sheet metal part on the lower mold and start the first rotary motor to clamp the sheet metal part with the clamping ring;

[0007] S2: Move the upper mold downwards to clamp the sheet metal part, and start the first rotary motor in reverse to make the sheet metal part rotate and move forward simultaneously;

[0008] S3: The pusher pushes the sheet metal part from the clamping ring into the space between the two limiting plates, and the sheet metal part is immersed in the electroplating solution;

[0009] S4: Power on terminals I and II, with terminal I as the negative terminal and terminal II as the positive terminal;

[0010] S5: Rotate the wheel to drive the metal plate to move and change the contact position between the sheet metal part and the metal plate. Attached Figure Description

[0027] like Figure 6-7 As shown, this example demonstrates how to easily remove the oxide layer from the surface of rod-shaped aluminum alloy sheet metal parts.

[0028] The new energy vehicle sheet metal electroplating system includes a mold holder 201, a lower mold 202, a hydraulic cylinder 203, and an upper mold 204. The lower mold 202 is welded to the mold holder 201, the hydraulic cylinder 203 is screwed to the upper part of the lower mold 202, and the upper mold 204 is screwed to the other end of the hydraulic cylinder 203. Abrasive grains are provided above the lower mold 202 and below the upper mold 204, which allows the rod-shaped sheet metal parts to be placed above the lower mold 202. The hydraulic cylinder 203 can drive the upper mold 204 to move downward, so that the sheet metal parts are clamped between the lower mold 202 and the upper mold 204. When the sheet metal parts move, the abrasive grains on the lower mold 202 and the upper mold 204 can remove the oxide layer on the surface of the sheet metal parts, which facilitates subsequent electroplating processing and achieves the effect of easily removing the oxide layer on the surface of the rod-shaped aluminum alloy sheet metal parts.

[0029] like Figure 4-7 As shown, this example allows for the convenient rotation of the driven ring 105 while moving the skateboard 103.

[0030] The new energy vehicle sheet metal electroplating system also includes a slide 101, a threaded rod 102, a slide plate 103, a drive ring 104, and a driven ring 105. The slide 101 is welded to the top of the mold holder 201. The threaded rod 102 is rotatably connected inside the slide 101. The slide plate 103 is slidably connected to the slide 101. The drive ring 104 is rotatably connected inside the slide plate 103 and threadedly connected to the threaded rod 102. The driven ring 105 is rotatably connected to the slide plate 103. The drive ring 104 and the driven ring 105 are connected by a belt drive. The output shaft of a first rotary motor is keyed to the drive ring 104, which drives the drive ring 104 to rotate. The drive ring 104 can then move forward along the threaded rod 102, which in turn drives the slide plate 103 to move forward. The drive ring 104 can then drive the driven ring 105 to rotate via the belt, thus facilitating the rotation of the driven ring 105 when the slide plate 103 is moved.

[0031] like Figure 4-7 As shown, this example allows for easy clamping of sheet metal parts between the clamps 108.

[0032] Since the new energy vehicle sheet metal electroplating system also includes a threaded ring 106, a stop bar 107, a clamping ring 108, and a baffle 205, the threaded ring 106 is threadedly connected to the driven ring 105. Two clamping rings 108 are fixedly connected to the threaded ring 106. The stop bar 107 is fixedly connected to the threaded ring 106. The baffle 205 is fixedly connected to the upper grinding mold 204. Therefore, when the upper grinding mold 204 is not moving downwards, the baffle 205 blocks the stop bar 107, preventing the threaded ring 106 from rotating with the driven ring 105. This, in turn, starts the first rotary motor, driving the sliding plate. When 103 moves outward, the driven ring 105 rotates, driving the threaded ring 106 to slide inward. When the sheet metal part is placed on the lower mold 202, the front end of the sheet metal part is placed between the two clamping rings 108. The two clamping rings 108 then move into the driven ring 105, clamping the sheet metal part. When the upper mold 204 moves downward, the baffle 205 no longer blocks the stop rod 107, and the threaded ring 106 can rotate with the driven ring 105, thus achieving the effect of easily clamping the sheet metal part between the clamping rings 108.

[0033] like Figure 4-7 As shown, this example can facilitate the ejection of sheet metal parts from clamp 108.

[0034] Since the new energy vehicle sheet metal electroplating system also includes a push plate 206, a push column 207, and a tension spring 208, the push plate 206 is rotatably connected to the mold holder 201, the push column 207 is slidably connected to the mold holder 201, one end of the push column 207 is rotatably connected to the push plate 206, and the tension spring 208 is fixedly connected between the push column 207 and the mold holder 201. A stop is provided on the mold holder 201, so when the slide plate 103 moves to the other side of the slide 101, the stop... On the stop lever 107, the threaded ring 106 is prevented from rotating together with the driven ring 105, thereby causing the clamping ring 108 to move outward from the driven ring 105, loosening the sheet metal part. Then, the stop lever 107 pushes the push plate 206 to rotate, and the push plate 206 drives the push column 207 to slide forward, pushing the sheet metal part out of the clamping ring 108. Then, the tension spring 208 can reset the push column 207 for the next processing, thereby achieving the effect of easily pushing the sheet metal part out of the clamping ring 108.

[0035] like Figure 8-9 As shown, this example can facilitate the pushing of sheet metal parts into the two limiting plates 302.

[0036] Since the new energy vehicle sheet metal electroplating system also includes an electroplating liquid tank 301 and two limiting plates 302, the electroplating liquid tank 301 is fixedly connected to the bottom of the mold frame 201, and the two limiting plates 302 are fixedly connected inside the electroplating liquid tank 301. Each limiting plate 302 is provided with an inclined plate above it. The electroplating liquid tank 301 is filled with electroplating liquid. When the sheet metal parts fall from the clamping ring 108, the two inclined plates can guide the sheet metal parts between the two limiting plates 302, so that the sheet metal parts are immersed in the electroplating liquid in the electroplating liquid tank 301, thereby achieving the effect of facilitating the pushing of the sheet metal parts into the two limiting plates 302.

[0037] like Figure 8-9 As shown, this example demonstrates how sheet metal parts can be connected to a cathode via a metal sheet 306.

[0038] Since the new energy vehicle sheet metal electroplating system also includes terminal block I 307 and rotating frame 308, each limiting piece 302 is rotatably connected to a rotating rod 303, and several metal pieces 306 are welded to each rotating rod 303. The rotating frame 308 is welded to the top of the electroplating liquid tank 301, and two rotating rods 303 are rotatably connected to the rotating frame 308. Terminal block I 307 is fixedly connected to the top of the rotating frame 308. When terminal block I 307 is energized, terminal block I 307 is used as the negative terminal, and the current is transmitted to the sheet metal parts through the metal pieces 306. The sheet metal parts are then connected to the cathode of the power supply, thus achieving the effect of connecting the sheet metal parts to the cathode through the metal pieces 306.

[0039] like Figure 8-9 As shown, this example can achieve the effect of changing the contact position between the sheet metal part and the metal sheet 306.

[0040] Since the new energy vehicle sheet metal electroplating system also includes a gear set 304 and a rotating wheel 305, the two ends of the gear set 304 are fixedly connected to two rotating rods 303 respectively, and the rotating wheel 305 is rotatably connected to the electroplating liquid tank 301. The rotating wheel 305 is fixedly connected to the rotating rod 303 on one side. Rotating the rotating wheel 305 can drive the gear set 304 to rotate, and the gear set 304 can drive the two rotating rods 303 to rotate in opposite directions. This causes the metal plate 306 on the rotating rod 303 to change its angle, thereby changing the contact position between the sheet metal part and the metal plate 306. This changes the position of the electrical contact point of the sheet metal part, allowing the electrical contact point of the sheet metal part to be electroplated as well, thus achieving the effect of changing the contact position between the sheet metal part and the metal plate 306.

[0041] like Figure 8-11 As shown, this example allows for easy rotation of the clamp 403 in the electroplating solution.

[0042] Since the new energy vehicle sheet metal electroplating system also includes a rotating shaft 401, a rotating ring 402 and two clamps 403, the rotating shaft 401 is fixedly connected above the electroplating solution tank 301, the rotating ring 402 is rotatably connected to the rotating shaft 401, and the two clamps 403 are fixedly connected to the left and right sides of the rotating ring 402 respectively. The rotating ring 402 is keyed to the output shaft of a second rotary motor, so that the second rotary motor can drive the rotating ring 402 to rotate around the rotating shaft 401, and then the rotating ring 402 drives the two clamps 403 to rotate in the electroplating solution tank 301, thereby achieving the effect of facilitating the rotation of the clamps 403 in the electroplating solution.

[0043] like Figure 10-11 As shown, this example allows for easy clamping of the coated metal plate 406 onto the clamp 403.

[0044] Since the sheet metal electroplating system for new energy vehicles also includes two clamping plates 405 and a terminal block II 407, the two clamping plates 405 are slidably connected to the left and right sides of the rotating ring 402. A compression spring 404 is fixedly connected between each clamping plate 405 and the rotating ring 402. Several plating metal plates 406 are provided between each clamping plate 405 and the clamping body 403. The terminal block II 407 is fixedly connected above the rotating shaft 401, so the compression spring 404 can press the clamping plate 405 against the clamping body 402. 3. The clamping plate 405 and the clamping body 403 tightly hold the several plated metal plates 406. When the plated metal plates 406 reduce their volume due to electroplating, they will not detach from the rotating ring 402. Then, the terminal II 407 is energized, and the terminal II 407 is used as the positive terminal. The current is then conducted into the plated metal plates 406 through the clamping body 403, so that the plated metal plates 406 can be connected to the positive terminal. This achieves the effect of easily clamping the plated metal plates 406 onto the clamping body 403.

[0045] A process for a sheet metal electroplating system for new energy vehicles includes the following steps:

[0046] S1: Place the sheet metal part on the lower mold 202, start the first rotary motor, and make the clamping ring 108 clamp the sheet metal part;

[0047] S2: Move the upper mold 204 downward to clamp the sheet metal part, and start the first rotary motor in reverse to make the sheet metal part rotate and move forward simultaneously;

[0048] S3: Push column 207 pushes the sheet metal part from the clamping ring 108 into the space between the two limiting pieces 302, and the sheet metal part is immersed in the electroplating solution;

[0049] S4: Power on terminals I 307 and II 407, with terminal I as the negative terminal and terminal II as the positive terminal;

[0050] S5: Rotate the wheel 305 to drive the metal plate 306 to move, changing the contact position between the sheet metal part and the metal plate 306.
