Description

Technical Field

[0001] This invention belongs to the field of aluminum plate embossing technology, specifically an embossing machine tool for the surface of aluminum plates for automotive parts. Background Technology

[0002] Embossing is a manufacturing process that creates regular textures such as straight lines, diamonds, or raised ridges on the surface of metal sheets through rolling. Extrusion embossing on aluminum sheets significantly improves the anti-slip properties of workpieces, facilitates assembly and gripping, and also serves decorative and branding functions. It is particularly widely used in automotive parts manufacturing, such as door trim panels, door sill trims, and dashboard decorative parts. With the increasing demands for lightweighting and surface quality in automobiles, the precision and efficiency of aluminum sheet embossing processes are receiving increasing attention.

[0003] Existing embossing machines mainly include a motor and transmission system for providing power, a pair of embossing rollers with patterned surfaces, bearing seats and pressure regulating devices for installing and adjusting the embossing rollers, and a clamping mechanism and frame for conveying and positioning aluminum sheets. The working process involves the motor driving the two embossing rollers to rotate in opposite directions via the transmission system. The aluminum sheet is fed between the rollers by a feeding mechanism. The embossing rollers apply sufficient pressure to the surface of the sheet, causing plastic flow in the surface layer, thereby forming the desired pattern.

[0004] However, the embossing machine in the aforementioned technology applies pressure to the workpiece surface through embossing rollers to induce plastic deformation. While this method can ensure forming quality for thick plates or rigid metal materials, it is difficult to precisely control the extrusion pressure of the embossing rollers when processing thin aluminum sheets or high-ductility aluminum alloy sheets commonly used in automotive parts. This is because the materials have lower hardness and thinner thickness. Excessive pressure can easily lead to warping, ripples, or localized dents on the sheet surface, damaging the overall flatness. Insufficient pressure results in insufficient pattern depth and blurred outlines, failing to meet the stringent standards for automotive exterior parts. Furthermore, different vehicle models often use aluminum sheets of varying thicknesses and grades. Existing equipment suffers from slow pressure adjustment response and cumbersome changeover adjustments, severely restricting processing efficiency and finished product yield, thus impacting the overall manufacturing level of automotive aluminum sheet parts.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 3As shown in the embodiment of the present invention, an embossing machine for the surface of aluminum plates for automotive parts includes a worktable 1; a fixed seat 2 is fixedly connected to one side of the top surface of the worktable 1; a movable seat 3 is slidably connected to the side of the top surface of the worktable 1 away from the fixed seat 2, and the movable seat 3 is driven by a hydraulic cylinder; embossing wheels 4 are rotatably connected to the sides of the fixed seat 2 and the movable seat 3 that are close to each other, and the embossing wheels 4 are connected to a motor through a universal joint coupling and a gearbox 18; a bearing seat 5 is installed on the top surface of the worktable 1 between the fixed seat 2 and the movable seat 3; the bearing seat A straight rod 6 is rotatably connected to the side of the embossing wheel 4; a plurality of evenly arranged rotating arms 7 are rotatably connected to the surface of the straight rod 6; a drive arm 8 is rotatably connected to the side of the rotating arm 7 near the straight rod 6; a drive rod 9 is rotatably connected to the end of the drive arm 8 away from the rotating arm 7, and the end of the drive arm 8 away from the rotating arm 7 is slidably connected to the straight rod 6; a fixing component is installed between the drive rod 9 and the support seat 5; the fixing component is used to lock the position of the drive rod 9; the ends of the rotating arms 7 away from the straight rod 6 rotate together. There is a stop plate 10; during operation, when it is necessary to perform knurling on a cylindrical workpiece, this embodiment of the invention can be used. First, the user needs to place the cylindrical workpiece to be processed onto the straight rod 6, then move the drive rod 9, which drives the drive arm 8 to slide on the surface of the straight rod 6, thereby pushing the rotating arm 7 to rotate, so that the rotating arm 7 drives the stop plate 10 to press against the inner wall of the cylindrical workpiece. Then, the position of the column drive rod 9 is locked by the fixing component. After that, the moving seat 3 drives the knurling wheel at the moving seat 3 to move towards the knurling wheel at the fixed seat 2, thereby making The knurling wheels at the movable seat 3 and the fixed seat 2 clamp the cylindrical workpiece between them. With the rotation of the two knurling wheels, patterns are finally engraved on the surface of the cylindrical workpiece. Through the cooperation of the drive rod 9, drive arm 8, rotating arm 7 and the abutment plate 10, when the cylindrical workpiece is squeezed by the two knurling wheels, the abutment can provide support for the cylindrical workpiece from the inside, thereby reducing the probability of deformation of the cylindrical workpiece and avoiding subsequent straightening operations. This improves both product quality and final production efficiency.

[0022] like Figure 3As shown, the fixing assembly includes a pair of symmetrically arranged cylinders 11; the cylinders 11 are embedded in the surface of the bearing seat 5 near the drive rod 9; the telescopic ends of the two cylinders 11 are slidably connected to the compression ring 12; one end of each of the multiple drive rods 9 is fixed to the compression ring 12; during operation, when it is necessary to move the drive rod 9, the user can activate the cylinders 11, which push the compression ring 12 to move, and then the compression ring 12 drives the drive rod 9, drive arm 8 and rotating arm 7 to move or rotate, thereby pressing the abutment plate 10 against the inner wall of the cylindrical workpiece. After that, the cylinders 11 always remain in the ejected state, thereby achieving the locking effect of the drive rod 9. At the same time, the cylinders 11 and the compression ring 12 push the drive rod 9 synchronously, which also avoids the user manually adjusting the drive rod 9, thereby reducing the user's operating difficulty and improving the ease of use of the embodiment.

[0023] like Figures 1 to 2 As shown, a movable plate 13 is slidably connected between two knurling wheels on the top surface of the worktable 1; a push plate 14 is slidably connected to the top surface of the movable plate 13, and the push plate 14 is driven by a servo motor; a pair of symmetrically arranged screws 15 are rotatably connected to the top surface of the push plate 14 at the corresponding position of the bearing seat 5; the threads of the two screws 15 are opposite in direction, and the screws 15 are driven by a servo motor; both screws 15 are threadedly connected to the bearing seat 5; during operation, before the user performs knurling on a cylindrical workpiece, it is necessary to adjust the cylindrical surface... The cylindrical workpiece is clamped. At this time, the user only needs to place the cylindrical workpiece on the top surface of the moving plate 13. Then the moving plate 13 will drive the support seat to move towards the cylindrical workpiece and insert the straight rod 6 into the inside of the cylindrical workpiece. Then the cylinder 11 is activated and the abutment plate 10 abuts against the inner wall of the cylindrical workpiece, thereby fixing the cylindrical workpiece. Then the servo motor drives the screw 15 to rotate, thereby driving the support seat 5 and the cylindrical workpiece to rise together between the two knurling wheels, thus automatically feeding the cylindrical workpiece, thereby improving the processing efficiency of the cylindrical workpiece.

[0024] like Figure 2 and Figure 4 As shown, a driven plate 16 is slidably connected to the end of the top surface of the movable plate 13 away from the push plate 14; toothed plates 17 are fixedly connected to the sides of the driven plate 16 and the push plate 14 that are close to each other; a gear 18 is rotatably connected to the top surface of the movable plate 13 between the two toothed plates 17, and the gear 18 is meshed with the two toothed plates 17; a support rod 19 is fixedly connected to the top surface of the driven plate 16; during operation, when the push plate 14 drives the bearing seat 5 to move towards the cylindrical workpiece, the push plate 14 will drive the driven plate 16 and the support rod 19 on the other side to move towards the push plate 14 through the transmission of the toothed plates 17 and the gear 18, and finally the support rod 19 moves to the end of the straight rod 6 away from the bearing seat 5, so that the straight rod 6 can be supported, avoiding deformation of the straight rod 6 after long-term use, which would affect the final product quality.

[0025] like Figures 1 to 2 As shown, a bearing 20 is fixedly connected to the top surface of the support rod 19; a connecting ring 21 is fixedly connected to the inner side of the bearing 20; a pair of symmetrically arranged slots 22 are opened on the surface of the connecting ring 21; a pair of symmetrically arranged mating blocks 23 are fixedly connected to the side of the straight rod 6 near the connecting ring 21, and the mating blocks 23 are adapted to the slots 22; during operation, when the support rod 19 moves towards the end of the straight rod 6, the bearing 20 at the top of the support rod 19 also moves towards the end of the straight rod 6, so that the mating block 23 at the end of the straight rod 6 is inserted into the slot 22 on the surface of the connecting ring 21. At this time, in addition to cooperating with the support rod 19 to support the straight rod 6, the bearing 20 can also limit the straight plate through the cooperation between the slot 22 and the mating block 23 on the surface of the connecting ring, thereby reducing the shaking of the cylindrical workpiece during the processing and ensuring the processing quality of the cylindrical workpiece.

[0026] like Figure 2 , Figure 6 and Figure 7 As shown, the top surface of the workbench 1 is provided with a pair of sliding grooves 24; the bottom surface of the moving plate 13 is fixedly connected to a pair of symmetrically arranged limiting plates 25 at corresponding positions of the two sliding grooves 24; the two sliding grooves 24 are slidably connected to a limiting rod 26, and the limiting rod 26 extends to the outside of the workbench 1; a plurality of evenly arranged springs 27 are fixedly connected between the limiting rod 26 and the pair of limiting plates 25; the surface of the limiting rod 26 is threadedly connected to a threaded rod 28, and the threaded rod 28 extends to the outside of the workbench 1; during operation, when the bearing seat 5 and the straight rod 6 drive the cylindrical workpiece to rise between the two knurling wheels, the moving seat 3 will drive the knurling wheel on one side of itself to move towards the fixed seat 2, and clamp the cylindrical workpiece between the two knurling wheels. Then, the knurling wheel extrudes the surface of the cylindrical workpiece through the helical teeth on its surface, thereby extruding a groove on the surface of the cylindrical workpiece that matches the knurling wheel. During this period, the knurling wheel at the moving seat 3 always maintains the alignment with the fixed seat 2. The extrusion of the cylindrical workpiece causes grooves to be extruded from its surface, causing the moving plate 13 and the limiting plate 25 to shift along the slide groove 24 toward the fixed seat 2. At this time, the cylindrical workpiece will be driven by the straight rod 6 and the bearing seat 5 to shift the moving plate 13 and the limiting plate 25 toward the fixed seat 2, thereby causing the limiting plate 25 to compress and stretch the spring 27 on one side, thus ensuring the smooth processing of the cylindrical workpiece. After the cylindrical workpiece is processed, the moving seat 3 moves the knurling wheel on one side away from the cylindrical workpiece, and the springs 27 on both sides of the limiting rod 26 return to their original position, causing the moving plate 13 to return to its original position, thereby causing the cylindrical workpiece to disengage from the knurling wheel on one side of the fixed seat 2, making it easier to remove the cylindrical workpiece. At the same time, while processing cylindrical workpieces of different sizes, the user can also screw on the threaded rod 28 to adjust the position of the limiting rod 26 and the moving plate 13 to adapt to cylindrical workpieces of different sizes.

[0027] like Figures 6 to 8 As shown, a sliding rod 29 is fixedly connected to the side of the worktable 1 near the limiting rod 26 extending to the outside of the worktable 1; a ruler 30 is slidably connected to the surface of the sliding rod 29, and the ruler 30 is locked to the sliding rod 29 by bolts; an indicator plate 31 is fixedly connected to the side of the limiting rod 26 near the ruler 30; during operation, when the user rotates the threaded rod 28 to move the limiting rod 26, the indicator plate 31 at the end of the limiting rod 26 will also move along with the limiting rod 26, so that the user can observe the position of the indicator plate 31 on the ruler 30, determine the distance between the axis of the straight rod 6 and the knurling wheel at the fixed seat 2, and thus adapt to the radius of the cylindrical workpiece, thereby facilitating the user to adjust the limiting rod 26, reducing the difficulty of operation for the user, and improving the usability of the embodiment of the present invention.

[0028] like Figures 6 to 8 As shown, a support plate 32 is fixedly connected to the side of the ruler 30 away from the indicator plate 31; a laser level 33 is fixedly connected to the top surface of the support plate 32; during operation, when the user changes to a knurled wheel of different diameters, the user can also slide the ruler 30 on the slide bar 29. During this process, the user needs to open the end of the ruler 30 and the laser level 33 at the support plate 32. The laser level 33 projects a laser onto the surface of the knurled wheel, thereby facilitating the user to adjust the end of the ruler 30 so that its end can be aligned with the outer edge of the knurled wheel, thus facilitating the user's adjustment of the ruler 30.

[0029] like Figure 2 and Figure 9 As shown, the bottom of the fixed base 2 is provided with a clearance groove 34; a conveyor belt 35 is installed on the top surface of the workbench 1 at the clearance groove 34; a pair of symmetrically arranged push rods 36 are slidably connected to the top surface of the workbench 1 on the side of the conveyor belt 35 near the moving plate 13, and the push rods 36 are driven by the air pump inside the workbench 1; an electric push rod 37 is embedded in the bottom of the moving base 3; a vacuum suction cup 38 is fixedly connected to the telescopic end of the electric push rod 37; during operation, in order to facilitate continuous feeding in this embodiment of the invention, the user can transport the cylindrical workpiece to be processed to the conveyor belt 35, and then the cylindrical workpiece will be conveyed by the conveyor belt 35. The workpiece passes through the clearance groove 34 and abuts against the top rod 36. Then, the electric push rod 37 at the moving seat 3 drives the vacuum suction cup 38 to adsorb the cylindrical workpiece at the end of the conveyor belt 35. Subsequently, the top rod 36 descends, and the electric push rod 37 drives a vacuum suction cup 38 to move to the moving plate 13. Then, the top rod 36 rises, separating the cylindrical workpiece at the conveyor belt 35 from the cylindrical workpiece at the moving plate 13. This completes the single loading of the cylindrical workpiece. After each cylindrical workpiece is processed, the previous loading operation can be repeated, thus realizing the continuous loading operation of the cylindrical workpiece and improving the processing efficiency of the embodiment of the present invention.

[0030] like Figures 1 to 2As shown, a guide groove 39 is provided on the top surface of the workbench 1 near the movable seat 3; a collection box 40 is fixedly connected to the side of the workbench 1 away from the fixed seat 2 at the position corresponding to the guide groove 39; during operation, after the cylindrical workpiece is processed, the electric push rod 37 still uses the vacuum suction cup 38 to pick up the processed cylindrical workpiece and move it to the guide groove 39. Then the vacuum suction cup 38 stops picking up the cylindrical workpiece, and the cylindrical workpiece will slide into the guide groove 39 and slide into the collection box 40 under the guidance of the guide groove 39, thus completing the unloading and collection operation of the cylindrical workpiece.

[0031] When performing knurling on a cylindrical workpiece, this embodiment of the invention can be used. First, the user places the cylindrical workpiece to be processed onto the straight rod 6. Then, the drive rod 9 is moved, causing the drive arm 8 to slide on the surface of the straight rod 6, thereby pushing the rotating arm 7 to rotate. This causes the rotating arm 7 to push the abutment plate 10 against the inner wall of the cylindrical workpiece. The position of the drive rod 9 is then locked by the fixing assembly. Afterward, the moving seat 3 moves the knurling wheel at the moving seat 3 towards the knurling wheel at the fixed seat 2, thereby causing the moving seat... The knurling wheels at points 3 and 2 clamp the cylindrical workpiece between them. With the rotation of the two knurling wheels, patterns are finally engraved on the surface of the cylindrical workpiece. Through the cooperation of the drive rod 9, drive arm 8, rotating arm 7 and abutment plate 10, when the cylindrical workpiece is squeezed by the two knurling wheels, the abutment can provide support for the cylindrical workpiece from the inside, thereby reducing the probability of deformation of the cylindrical workpiece and avoiding subsequent straightening operations. This improves both product quality and final production efficiency.

[0032] When it is necessary to move the drive rod 9, the user can activate the cylinder 11, which pushes the extrusion ring 12 to move. The extrusion ring 12 then drives the drive rod 9, drive arm 8, and rotating arm 7 to move or rotate, thereby pressing the abutment plate 10 against the inner wall of the cylindrical workpiece. Afterward, the cylinder 11 remains in the ejected state, thus achieving a locking effect on the drive rod 9. At the same time, the cylinder 11 and the extrusion ring 12 push the drive rod 9 synchronously, which also avoids the user manually adjusting the drive rod 9, thereby reducing the user's operating difficulty and improving the ease of use of the embodiment.

[0033] Before the user performs knurling on the cylindrical workpiece, the cylindrical workpiece needs to be clamped. At this time, the user only needs to place the cylindrical workpiece on the top surface of the moving plate 13. Then the moving plate 13 will drive the receiving seat to move towards the cylindrical workpiece and insert the straight rod 6 into the inside of the cylindrical workpiece. Then the cylinder 11 is activated and the abutment plate 10 abuts against the inner wall of the cylindrical workpiece, thereby fixing the cylindrical workpiece. Then the servo motor drives the screw 15 to rotate, thereby driving the bearing seat 5 and the cylindrical workpiece to rise together between the two knurling wheels, thus automatically feeding the cylindrical workpiece, thereby improving the processing efficiency of the cylindrical workpiece.

[0034] When the push plate 14 drives the bearing seat 5 to move toward the cylindrical workpiece, the push plate 14 will drive the driven plate 16 and the support rod 19 on the other side to move toward the push plate 14 through the transmission of the toothed plate 17 and the gear 18. Finally, the support rod 19 moves to the end of the straight rod 6 away from the bearing seat 5, so that the straight rod 6 can be supported and avoid deformation of the straight rod 6 after long-term use, which would affect the final product quality.

[0035] When the support rod 19 moves toward the end of the straight rod 6, the bearing 20 at the top of the support rod 19 also moves toward the end of the straight rod 6, eventually causing the mating block 23 at the end of the straight rod 6 to insert into the slot 22 on the surface of the connecting ring 21. At this time, in addition to supporting the straight rod 6 with the support rod 19, the bearing 20 can also limit the straight plate through the cooperation between the slot 22 on the connecting ring surface and the mating block 23, thereby reducing the shaking of the cylindrical workpiece during the processing and ensuring the processing quality of the cylindrical workpiece.

[0036] When the support seat 5 and the straight rod 6 lift the cylindrical workpiece between the two knurling wheels, the movable seat 3 will move the knurling wheel on one side towards the fixed seat 2, clamping the cylindrical workpiece between the two knurling wheels. Then, the knurling wheels will press the surface of the cylindrical workpiece with their helical teeth, thus extruding grooves that match the knurling wheels. During this process, the knurling wheel at the movable seat 3 will always maintain pressure on the cylindrical workpiece. After the cylindrical workpiece is extruded into the grooves, the movable plate 13 and the limiting plate 25 will shift along the slide 24 towards the fixed seat 2. At this time, the cylindrical workpiece will be driven by the straight rod 6 and the support seat 5 to move the movable plate 13 and the limiting plate. The limit plate 25 shifts towards the fixed seat 2, causing the limit plate 25 to compress and stretch the spring 27 on one side, thus ensuring the smooth processing of the cylindrical workpiece. After the cylindrical workpiece is processed, the moving seat 3 moves the knurling wheel on one side away from the cylindrical workpiece, and the springs 27 on both sides of the limit rod 26 return to their original position, causing the moving plate 13 to return to its original position. This causes the cylindrical workpiece to disengage from the knurling wheel on one side of the fixed seat 2, making it easier to remove the cylindrical workpiece. At the same time, while processing cylindrical workpieces of different sizes, the user can also screw on the threaded rod 28 to adjust the position of the limit rod 26 and the moving plate 13 to adapt to cylindrical workpieces of different sizes.

[0037] When the user screws the threaded rod 28 to move the limiting rod 26, the indicator plate 31 at the end of the limiting rod 26 will also move along with the limiting rod 26. At this time, the user can observe the position of the indicator plate 31 on the ruler 30, determine the distance between the axis of the straight rod 6 and the knurling wheel at the fixed seat 2, and thus adapt to the radius of the cylindrical workpiece. This makes it convenient for the user to adjust the limiting rod 26, reduces the difficulty of operation for the user, and improves the usability of the embodiment of the present invention.

[0038] When the user changes to a knurling wheel of different diameters, the user can also slide the ruler 30 on the slide bar 29. During this process, the user needs to open the laser level 33 at the end of the ruler 30 and the support plate 32. The laser level 33 projects a laser onto the surface of the knurling wheel, which makes it convenient for the user to adjust the end of the ruler 30 so that the end can be aligned with the outer edge of the knurling wheel, thus facilitating the user's adjustment of the ruler 30.

[0039] To facilitate continuous feeding in this embodiment of the invention, the user can transport the cylindrical workpiece to be processed to the conveyor belt 35. The cylindrical workpiece will then pass through the relief groove 34 and abut against the push rod 36 under the conveyor belt 35. Then, the electric push rod 37 at the moving seat 3 drives the vacuum suction cup 38 to pick up the cylindrical workpiece at the end of the conveyor belt 35. Then, the push rod 36 descends, and the electric push rod 37 drives a vacuum suction cup 38 to move to the moving plate 13. Then, the push rod 36 rises, separating the cylindrical workpiece at the conveyor belt 35 from the cylindrical workpiece at the moving plate 13. This completes the single feeding of the cylindrical workpiece. After each cylindrical workpiece is processed, the previous feeding operation can be repeated, thus realizing continuous feeding of cylindrical workpieces and improving the processing efficiency of this embodiment of the invention.

[0040] After the cylindrical workpiece is processed, the electric actuator 37 still uses the vacuum suction cup 38 to pick up the processed cylindrical workpiece and move it to the guide groove 39. Then the vacuum suction cup 38 stops picking up the cylindrical workpiece, and the cylindrical workpiece will slide into the guide groove 39 and slide into the collection box 40 under the guidance of the guide groove 39. This completes the unloading and collection operation of the cylindrical workpiece.
