Description

Technical Field

[0001] This invention relates to the field of automotive aluminum alloy component processing, and more particularly to a laser forming equipment and method for automotive aluminum alloy components. Background Technology

[0002] Automotive aluminum alloy components refer to automotive parts manufactured using aluminum alloy materials through processes such as casting, stamping, extrusion, or additive manufacturing. These components possess characteristics such as lightweight, high strength, and corrosion resistance, and are widely used in vehicle body structures, powertrain systems, chassis, and battery pack housings. They are key components for improving the range of new energy vehicles and reducing energy consumption and emissions in gasoline vehicles. Typical processes include laser welding, thermoforming, and 3D printing.

[0003] In the field of laser forming of automotive aluminum alloy components, existing equipment has several shortcomings in powder handling. Firstly, powder easily adheres to the scraper during its movement; if not cleaned promptly, it will affect subsequent powder filling and make it difficult to evenly fill the forming chamber, thus impacting the forming accuracy and consistency of the components. Secondly, adjusting the powder height in the forming chamber and powder supply chamber often requires separate operations, which is inefficient and makes it difficult to ensure coordination between the powder heights of the two chambers, hindering the effective pushing of the powder by the driving mechanism. Furthermore, the observation window on the equipment is easily contaminated by powder and fumes during processing, making it difficult for operators to clearly observe the processing progress, monitor the equipment's operating status and forming condition, and ultimately affecting production efficiency and product quality. Summary of the Invention

[0013] Preferably, a laser mechanism is installed in the processing chamber, and a rotating door is rotatably connected to the surface of the processing chamber via a hinge, with an observation window provided on the rotating door.

[0014] A method for preparing a laser forming equipment for automotive aluminum alloy components includes the following steps: Step 1: Place aluminum alloy powder into the forming chamber and the powder supply chamber, and compact it. Then, melt the aluminum alloy powder in the forming chamber using a laser mechanism. After one layer is melted, start the second motor. The second motor drives the second turntable to rotate. When the second turntable rotates, it drives the drive rod to rotate through the drive groove. When the drive rod rotates, it drives the first gear to rotate through the rotating rod. When the first gear rotates, it drives the second lifting plate to move vertically downward along the inner wall of the forming chamber through the first racks on both sides. The third lifting plate moves vertically upward along the inner wall of the powder supply chamber.

[0015] Step two: After the aluminum alloy powder layer height is adjusted, start the first motor. The first motor drives the first conveyor wheel to rotate. When the first conveyor wheel rotates, it works with the second conveyor wheel and the track to drive the drive rod. When the drive rod is in motion, it drives the scraper to slide back and forth in a straight line along the surface of the first slide rod through the slide groove. When the scraper slides, it pushes the aluminum alloy powder protruding from the powder supply chamber and pushes it into the forming chamber. During the scraper's back and forth motion, since the second gear meshes with the second rack, when the second gear moves in a straight line, it drives the transmission rod to rotate. When the transmission rod rotates, it drives the drive block to move through the cam groove on its surface. When the drive block moves, it drives the push plate to slide back and forth in a straight line along the surface of the second slide rod. When the push plate slides, it cleans the powder attached to the scraper.

[0016] Step 3: After the aluminum alloy powder is leveled, the laser mechanism is restarted to melt the aluminum alloy powder in the forming chamber, and then the leveling process in Step 2 is repeated.

[0017] Compared with the prior art, the present invention has the following beneficial effects: With a pushing mechanism, the first motor drives the first conveyor wheel to rotate. The first conveyor wheel, together with the second conveyor wheel and the track, drives the drive rod. When the drive rod is in motion, it drives the scraper to slide back and forth in a straight line along the surface of the first slide rod through the slide groove. When the scraper slides, it pushes the aluminum alloy powder protruding from the powder supply chamber and pushes it into the forming chamber. During the reciprocating motion of the scraper, the cam groove and the drive block drive the push plate to slide back and forth in a straight line along the surface of the second slide rod. When the push plate slides, it cleans the powder attached to the scraper and also facilitates the filling of powder into the forming chamber. The system incorporates an adjustment mechanism, using a second motor to drive a second turntable. This turntable, in turn, drives a drive rod via a drive groove. The drive rod, in turn, drives a first gear via a rotating rod. The first gear, in turn, drives two first racks on either side, causing a second lifting plate to move vertically downwards along the inner wall of the forming chamber, and a third lifting plate to move vertically upwards along the inner wall of the powder supply chamber. This achieves the purpose of lowering the forming chamber and raising the powder supply chamber, simultaneously adjusting the powder height in both chambers and facilitating the powder-moving mechanism. A cleaning mechanism is also included. A rotating handle drives a rotating plate at one end of a shaft. This plate, when rotating, cleans the observation window with a sponge, preventing impurities from adhering to the window and affecting viewing.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides a laser forming device for automotive aluminum alloy components, including a processing chamber 100. The processing chamber 100 is equipped with a pushing mechanism 300, an adjusting mechanism 200, and a cleaning mechanism 400. The adjusting mechanism 200 uses a second motor 205 to drive a second turntable 206 to rotate. When the second turntable 206 starts rotating, it drives a drive groove 203 to rotate. The drive groove 203 is an annular groove with notches on both sides, separated by inclined baffles. Figure 8As shown, a drive rod 220 on the surface of the first turntable 207 is located within the drive groove 203. Initially, the drive rod 220 remains relatively stationary during the initial rotation of the drive groove 203. When the drive groove 203 rotates to the point where the baffle contacts the drive rod 220, the inclined baffle applies a tangential thrust to the drive rod 220, forcing it to move along the inclined surface of the baffle and eventually disengage from the drive groove 203. During this process, the movement of the drive rod 220 causes the first turntable 207 to rotate. As the first turntable 207 rotates, the next adjacent drive rod 220 will pass through the drive groove 203. The gap re-enters the groove until it contacts the baffle again. Through this cyclical mechanical interaction, the continuous rotation of the second turntable 206 is converted into the intermittent stepping rotation of the first turntable 207, realizing the conversion and transmission of motion. When the first turntable 207 rotates, it drives the first gear 221 to rotate through the rotating rod 215. When the first gear 221 rotates, it drives the second lifting plate 211 to move vertically downward along the inner wall of the forming chamber 208 through the first racks 217 on both sides. The third lifting plate 212 moves vertically downward along the inner wall of the powder supply chamber 213. The wall moves vertically upwards, thereby lowering the forming chamber 208 and raising the powder supply chamber 213. This simultaneously adjusts the powder height within both chambers, facilitating the pushing mechanism's movement of the powder. A pushing mechanism 300 is provided, and a first motor 309 drives the first conveyor wheel 313 to rotate. The first conveyor wheel 313, in conjunction with the second conveyor wheel 314 and the track, drives the drive rod 312. During transmission, the drive rod 312, through the slide groove 315, drives the scraper 307 to slide linearly back and forth along the surface of the first slide rod 303. When the scraper 307 slides, it pushes the protruding aluminum alloy powder in the powder supply chamber 213 and pushes it into the forming chamber 208. During the reciprocating motion of the scraper 307, the cam groove and the drive block 306 drive the pusher 308 to slide linearly back and forth along the surface of the second slide bar 311. When the pusher 308 slides, it cleans the powder attached to the scraper 307 and also facilitates the filling of powder into the forming chamber 208. The adjustment mechanism 200 includes a recovery chamber 209 with an adjustable bottom height, a forming chamber 208, and a powder supply chamber 213. The pushing mechanism 300 includes a first slide rod 303, which is fixedly installed inside the processing chamber 100. The first slide rod 303 is used to support the sliding of the scraper 307.

The first motor 309 is horizontally positioned and is used to drive the first conveyor wheel 313 to rotate. The shaft end of the first motor 309 passes through the vertical plate 301 and is fixedly connected to the first conveyor wheel 313. The scraper 307 is U-shaped.

By setting the second rack 305 and the second gear 304, when the second gear 304 moves linearly, it drives the second gear 304 to rotate. A drive block 306 is rotatably connected to the push plate 308. The drive block 306 is cylindrical and slides in the cam groove. The drive block 306 is set for sliding in the cam groove.

[0025] The adjusting mechanism 200 includes a connecting rod 201, which is fixedly installed on the inner wall of the processing chamber 100.

The cylinder 202 is used to lift the first lifting plate 210 so as to take out the powder in the recycling bin 209.

[0028] A mounting base 216 is fixedly installed on the inner wall of the processing chamber 100. The mounting base 216 is vertically arranged and is used to support the rotation of the rotating rod 215. The inner wall of the mounting base 216 is rotatably connected to the rotating rod 215, which is cylindrical in shape. The rotating rod 215 is used to support the installation of the first gear 221. The first gear 221 is fixedly installed at one end of the rotating rod 215 and is used to mesh with the first rack 217.

[0029] The bottom ends of both the second lifting plate 211 and the third lifting plate 212 are fixed with a first rack 217 and a reinforcing rod 222. The reinforcing rod 222 is designed to increase strength. One end of the reinforcing rod 222 is fixedly connected to the side of the first rack 217. The first gear 221 meshes with the first rack 217. The presence of the first rack 217 facilitates the movement of the second lifting plate 211 and the third lifting plate 212 when the first gear 221 rotates.

[0030] The cleaning mechanism 400 includes a shaft 403, which is rotatably connected to the processing chamber 100. The shaft 403 is used to support the installation of the rotating plate 402. The rotating plate 402 is fixedly installed at one end of the shaft 403, and a sponge 401 is fixedly installed on the surface of the rotating plate 402. The sponge 401 is used to clean the observation window 600. The other end of the shaft 403 passes through the processing chamber 100 and is fixedly installed with a handle 404. The handle 404 is used to rotate the shaft 403.

[0031] A laser mechanism 700 is installed inside the processing chamber 100. The laser mechanism 700 consists of a laser and a multi-axis motion platform, etc., which are existing known technologies and will not be described in detail. A rotating door 500 is connected to the surface of the processing chamber 100 by a hinge. The rotating door 500 is set to open the processing chamber 100. An observation window 600 is set on the rotating door 500 to observe the processing progress.

[0032] In use, the processing chamber 100 is opened through the rotary door 500. Aluminum alloy powder is then placed into the forming chamber 208 and the powder supply chamber 213 and compacted. The aluminum alloy powder in the forming chamber 208 is then melted by the laser mechanism 700. After one layer has melted, the second motor 205 is started, driving the second turntable 206 to rotate. When the second turntable 206 starts rotating, it drives the drive groove 203 to rotate. The drive groove 203 is an annular groove with notches on both sides, separated by inclined baffles, as shown in the attached diagram. Figure 8As shown, a drive rod 220 on the surface of the first turntable 207 is located within the drive groove 203. Initially, the drive rod 220 remains relatively stationary during the initial rotation of the drive groove 203. When the drive groove 203 rotates to the point where the baffle contacts the drive rod 220, the inclined baffle applies a tangential thrust to the drive rod 220, forcing it to move along the inclined surface of the baffle and eventually disengage from the drive groove 203. During this process, the movement of the drive rod 220 causes the first turntable 207 to rotate. As the first turntable 207 rotates, the next adjacent drive rod 220 will re-enter the groove through the notch in the drive groove 203 until it contacts the baffle again. Through this cyclical mechanical coordination, the continuous rotation of the second turntable 206 is transformed into the intermittent stepping rotation of the first turntable 207, realizing the conversion and transmission of motion. When the first turntable 207 rotates, it drives the first gear 221 to rotate through the rotating rod 215. When the first gear 221 rotates, it drives the second lifting plate 211 to move vertically downward along the inner wall of the forming chamber 208 through the first racks 217 on both sides. The third lifting plate 212 moves vertically upward along the inner wall of the powder supply chamber 213, thereby achieving the purpose of lowering the forming chamber 208 and raising the powder supply chamber 213.

[0033] After the aluminum alloy powder layer height is adjusted, the first motor 309 is started. The first motor 309 drives the first conveyor wheel 313 to rotate. When the first conveyor wheel 313 rotates, it works with the second conveyor wheel 314 and the track to drive the drive rod 312 for transmission. When the drive rod 312 is in transmission, it drives the scraper 307 to slide back and forth linearly along the surface of the first slide rod 303 through the slide groove 315. When the scraper 307 slides, it pushes the aluminum alloy powder protruding from the powder supply chamber 213 and pushes it into the forming chamber 208. During the reciprocating motion, since the second gear 304 meshes with the second rack 305, when the second gear 304 moves in a straight line, it will drive the transmission rod 310 to rotate. When the transmission rod 310 rotates, it will drive the drive block 306 to move through the cam groove on its surface. When the drive block 306 moves, it will drive the push plate 308 to slide back and forth in a straight line along the surface of the second slide rod 311. When the push plate 308 slides, it will clean the powder attached to the scraper 307 and also distribute the powder evenly to the forming chamber 208.

[0034] After the aluminum alloy powder is leveled, the laser mechanism 700 is restarted to melt the aluminum alloy powder in the forming chamber 208. The leveling process is then repeated until the workpiece is finished. During this period, the operator can observe the work through the observation window 600. When impurities adhere to the observation window 600, the handle 404 can be turned. The handle 404 drives the rotating plate 402 at one end of the shaft 403 to rotate. When the rotating plate 402 rotates, it will clean the observation window 600 through the sponge 401.

[0035] A method for preparing a laser forming equipment for automotive aluminum alloy components includes the following steps: Step 1: Place aluminum alloy powder into the forming chamber 208 and the powder supply chamber 213 and compact it. Then, melt the aluminum alloy powder in the forming chamber 208 through the laser mechanism 700. After one layer is melted, start the second motor 205. The second motor 205 drives the second turntable 206 to rotate. When the second turntable 206 rotates, it drives the drive rod 220 to rotate through the drive groove 203. When the drive rod 220 rotates, it drives the first gear 221 to rotate through the rotating rod 215. When the first gear 221 rotates, it drives the second lifting plate 211 to move vertically downward along the inner wall of the forming chamber 208 through the first racks 217 on both sides. The third lifting plate 212 moves vertically upward along the inner wall of the powder supply chamber 213.

[0036] Step two: After the aluminum alloy powder layer height is adjusted, start the first motor 309. The first motor 309 drives the first conveyor wheel 313 to rotate. When the first conveyor wheel 313 rotates, it works with the second conveyor wheel 314 and the track to drive the drive rod 312. When the drive rod 312 is in motion, it drives the scraper 307 to slide back and forth linearly along the surface of the first slide rod 303 through the slide groove 315. When the scraper 307 slides, it pushes the protruding aluminum alloy powder in the powder supply chamber 213 and pushes it to form the desired shape. Inside the bin 208, during the reciprocating motion of the scraper 307, the second gear 304 meshes with the second rack 305. Therefore, when the second gear 304 moves in a straight line, it will drive the transmission rod 310 to rotate. When the transmission rod 310 rotates, it will drive the drive block 306 to move through the cam groove on its surface. When the drive block 306 moves, it will drive the push plate 308 to slide back and forth in a straight line along the surface of the second slide rod 311. When the push plate 308 slides, it will clean the powder attached to the scraper 307.

[0037] Step 3: After the aluminum alloy powder is leveled, the laser mechanism 700 is restarted to melt the aluminum alloy powder in the forming chamber 208, and then the leveling work in step 2 is repeated.
