Description

Technical Field

[0001] This invention relates to the field of automotive interior processing technology, specifically to a punching equipment and processing method for automotive interior processing. Background Technology

[0002] In the automotive manufacturing industry, interior components such as door panel covers, armrest upholstery, and dashboard trim are typically made of multi-layered composite materials (e.g., knitted / non-woven fabrics combined with foam, PVC / PU artificial leather, etc.). These materials often have flocked, embossed, or short-fiber decorative layers on their surface to enhance tactile feel and aesthetics. During production, large rolls or sheets of composite materials are precisely cut into individual pieces according to the product's contours using a die-cutting process.

[0003] For example, patent CN213440101U, published on June 15, 2021, discloses a punching equipment for automotive interior panels, specifically relating to the automotive manufacturing field. It includes a punching die and a blanking die. A rotating support is rotatably fitted onto the bottom surface of the punching die, a sliding guide post is fixedly installed on the top surface of the punching die, a guide sleeve is fixedly installed on one side of the blanking die, a blanking die is provided on the top surface of the punching die, an elastic holding mechanism is fixedly installed on the periphery of the punching die, and a tool protection seat is fixedly installed on the bottom surface of the blanking die. The tool protection seat includes a protective pressure plate and an elastic telescopic rod, and a tool changer is detachably installed on the bottom surface of the blanking die. This utility model, by setting a rotating punching die structure, utilizes the punching die fitted onto the top surface of the rotating support to achieve simultaneous punching and material sheet fixing. Operators can simultaneously remove and fix the blanked material, shortening material change time and improving punching efficiency.

[0004] However, existing punching equipment still has significant shortcomings when processing such soft, multi-layered automotive interior composite materials with a velvety surface:

[0005] On the one hand, the material is prone to wrinkles or positional shifts after loading. If it is not effectively leveled and positioned, it will lead to deviations in the blanking contour, affecting assembly accuracy. On the other hand, during the blanking process, the flocking or short fibers on the material surface are easily broken and detached due to the extrusion of the die, and adhere to the lower surface of the upper blanking die. As continuous operation proceeds, these residues accumulate, which will not only contaminate the surface of subsequent automotive interior parts, forming indentations or dirt, but may also block the die vents, affecting the blanking quality. Summary of the Invention

[0006] The purpose of this invention is to provide a stamping equipment and processing method for automotive interior processing, so as to solve the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The aforementioned stamping equipment for automotive interior processing includes a pile handling mechanism comprising a vertical seat capable of moving laterally along the lower surface of the upper die, and a rotatable processing component mounted on the vertical seat.

[0011] The aforementioned stamping equipment for automotive interior processing includes a top seat and a slide bar. The slide bar is slidably disposed within the top seat and engages with the side opening of the top seat via a limiting block, allowing the height of the processed part to be adjusted.

[0012] The aforementioned stamping equipment for automotive interior processing includes a combing component comprising multiple spaced combing teeth. The combing component is fixed on the frame and performs directional combing of the surface fuzz of the automotive interior parts as the lower die moves.

The four sets of leveling mechanisms move outward synchronously to clamp and tension the four edges of the automotive interior parts.

[0014] The aforementioned stamping equipment for automotive interior processing has an elastic element between the pressure plate and the slide, and a limiting plate in the lower die for limiting the flipping angle of the pressure plate.

[0015] The aforementioned stamping equipment for automotive interior processing includes a straightening mechanism comprising a rotatable top plate, a rotating shaft, and a power component five.

[0019] Step 1: Automatically align the automotive interior parts placed on the lower mold;

[0020] Step 2: Use a leveling mechanism to clamp and tension the automotive interior parts to eliminate wrinkles;

[0021] Step 3: During the process of sending the lower die into the blanking station, the surface hairs are combed in a directional manner using a combing component;

[0022] Step 4: The upper and lower molds work together to complete the heated punching process;

[0023] Step 5: After punching, the lower surface of the upper die is automatically cleaned by a movable rotating processing component to remove the adhering lint.

[0024] The beneficial effects of the present invention are as follows: In the above technical solution, the present invention cleans away the lint that adheres to the upper mold due to heating during the molding process by setting a lint removal mechanism, thereby solving the problem that lint adhesion affects the subsequent molding quality of automotive interior parts and improving the molding quality of automotive interior parts.

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like Figures 1 to 13This invention provides a stamping device for automotive interior parts processing, comprising: a machine body 1, on which a molding mechanism 2 and a feeding mechanism 4 are provided; the molding mechanism 2 includes a frame 21, a drive component 22, an upper mold 23 and a lower mold 24, the upper mold 23 and the lower mold 24 are vertically aligned and have a built-in heating component 25; the upper mold 23 is provided with a lint removal mechanism 3 for cleaning the lint adhering to the lower surface of the upper mold 23; the frame 21 is provided with a combing component 5 for combing the lint on the surface of the automotive interior parts before molding; the lower mold 24 is provided with a leveling mechanism 6 and a straightening mechanism 7 for respectively flattening and rotating the automotive interior parts for straightening;

[0043] Specifically, the body 1 is provided with a molding mechanism 2, which is used to perform molding processing on automotive interior parts;

[0044] The molding mechanism 2 includes a frame 21, a drive component 22 is provided on the frame 21, an upper mold 23 is installed at the output end of the drive component 22, and a lower mold 24 is provided on the body 1. The upper mold 23 and the lower mold 24 are aligned in the vertical direction, and a heating component 25 is provided in both the upper mold 23 and the lower mold 24. The heating component 25 is used to heat the automotive interior parts.

[0045] In one embodiment of the present invention, the fluff processing mechanism 3 includes a vertical seat 35 that can move laterally along the lower surface of the upper mold 23, and a rotatable processing component 31 mounted on the vertical seat 35.

[0046] Specifically, the upper mold 23 is provided with a lint removal mechanism 3. The lint removal mechanism 3 includes a processing component 31 that can move along the lower surface of the upper mold 23. The lint removal mechanism 3 is used to clean the lint adhering to the lower surface of the upper mold 23 by moving the processing component 31 after the molding process.

[0047] Specifically, the heating component 25 is an electric heating plate, and there are two electric heating plates. The two electric heating plates are respectively set in the upper mold 23 and the lower mold 24. The processing component 31 is a rotatable roller brush. The roller brush can be driven to rotate by a motor. The rotatable roller brush moves along the lower surface of the upper mold 23 to clean the lint adhering to the lower surface of the upper mold 23. The driving component 22 is a hydraulic cylinder.

[0048] Specifically, an air extraction component can be installed near the roller brush. The air extraction component is an air pump, which can be equipped with multiple air extraction ends. The air extraction ends are located near the roller brush. When the roller brush removes the attached lint, it can suck up and collect the removed lint, thereby reducing the amount of lint that falls onto the lower mold 24 or other parts of the machine body 1. This reduces the need for manual cleaning of the fallen lint and reduces the labor intensity of manual labor.

[0049] The specific implementation scenario is as follows: During molding, the automotive interior parts are first placed on the lower mold 24. Then, the upper mold 23 is driven downward by a hydraulic cylinder. The upper mold 23 and the lower mold 24 perform molding processing on the automotive interior parts. Simultaneously, the electric heating plates installed inside the upper mold 23 and the lower mold 24 are energized to heat the automotive interior parts. However, because the surface of the automotive interior parts is textured with a velvet finish for comfort, and thicker automotive interior parts require a longer heating and molding time, the velvet on the surface of the automotive interior parts may cause issues during the heating and molding process. The lint tends to adhere to the surface of the upper mold 23. As more automotive interior parts are processed, more lint adheres to the surface of the upper mold 23. As processing continues, this can affect the molding quality of the automotive interior parts. Furthermore, the longer the lint adheres, the more difficult it is to clean. Therefore, after molding the automotive interior parts, the upper mold 23 is reset by driving a hydraulic cylinder, and a rotatable roller brush is driven to move along the lower surface of the upper mold 23. The roller brush cleans away the lint adhering to the upper mold 23, thus solving the problem of lint adhesion affecting the subsequent molding quality of automotive interior parts and improving the molding quality.

[0050] Further, please refer to the appendix to the instruction manual. Figure 4 The fluff processing mechanism 3 also includes a power component 32, the output end of which is fixedly connected to the processing component 31. The power component 32 is used to drive the processing component 31 to rotate. A second power component 33 is installed on the upper mold 23. A lead screw 34 is installed on the output end of the second power component 33. A vertical seat 35 is threadedly connected to the lead screw 34. The power component 32 is installed on the vertical seat 35.

[0051] Specifically, the power component 32 is an electric motor, and the processing component 31 is a rotatable roller brush. The roller brush is driven to rotate by the power component 32 for cleaning. After the molding process of the automotive interior parts, the roller brush is driven to rotate by the power component 32, and at the same time, the lead screw 34 is driven to rotate by the power component 33. The lead screw 34 is connected to the vertical seat 35 through the threaded engagement, which drives the roller brush to move along the lower surface of the upper mold 23 to clean off the lint adhering to the lower surface of the upper mold 23. This solves the problem of lint adhering to the lower surface of the upper mold 23, which affects the subsequent molding quality of the automotive interior parts, and improves the molding quality.

[0052] In one embodiment of the present invention, the vertical seat 35 includes a top seat 351 and a slide rod 352. The slide rod 352 is slidably disposed in the top seat 351 and cooperates with the side opening 3511 of the top seat 351 through a limiting block 3521, so that the height of the processing component 31 can be adjusted.

[0053] Further, please refer to the appendix to the instruction manual. Figure 4The vertical seat 35 includes a top seat 351 and a slide rod 352. The slide rod 352 is slidably disposed in the top seat 351. The top seat 351 is threadedly connected to the lead screw 34. The power component 32 is installed on the slide rod 352. A side opening 3511 is provided on the top seat 351. A limit block 3521 is fixedly disposed on the slide rod 352. The limit block 3521 is slidably disposed in the side opening 3511.

[0054] Specifically, by sliding the slide bar 352 within the top seat 351 and limiting it with the limiting block 3521 and the side opening 3511, the height of the roller brush is adjustable. When not performing molding, the processing part 31 is at its lowest height under the action of gravity, and at this time the processing part 31 is at the same height as the lower surface of the upper mold 23. During molding, as the upper mold 23 is driven to move downward, the processing part 31 will contact the lower mold 24, and the slide bar 352 can slide within the top seat 351, thereby solving the problem of interference between the presence of the processing part 31 and the molding process.

[0055] Further, please refer to the appendix to the instruction manual. Figure 5 The machine body 1 is provided with a feeding mechanism 4, which includes a power component 3 41. The output end of the power component 3 41 is equipped with a connecting seat 42, which is fixedly connected to the lower mold 24. The machine body 1 has an opening 43, and the connecting seat 42 is located in the opening 43. The top of the machine body 1 is provided with a guide rail 44, and the lower mold 24 is slidably mounted on the guide rail 44.

[0056] Specifically, the power component 3 41 is a cylinder, which drives the lower mold 24 to move on the surface of the machine body 1, so that when placing automotive interior parts, the lower mold 24 can be moved out of the frame 21. After the automotive interior parts are placed, the lower mold 24 is driven to reset and move again by the cylinder, so that the automotive interior parts can be placed easily, and the problem of inconvenience in placing automotive interior parts caused by the obstruction of the frame 21 is solved.

[0057] However, in the above technical solutions, because automotive interior parts have fuzz, and the molding process involves heating and pressure treatment to change the shape of the automotive interior parts or enhance certain properties, when it is necessary to form specific textures or patterns on the automotive interior parts, grooves corresponding to the textures or patterns are usually set on the mold. Furthermore, since fuzz is a loose fiber, when the fuzz on the surface of the automotive interior parts is disordered, it is easy for the fuzz to overfill the fine grooves of the mold during molding (overfilling the mold refers to disordered fuzz, with some fuzz piled up). When the piled-up fibers accumulate in the mold groove, it can easily cause excessive filling of the mold groove. Therefore, the messy fibers can hinder the clear formation of the texture pattern. This filling can prevent the mold from pressing completely, resulting in blurred pattern details, which in turn affects the processing quality of the automotive interior parts, the overall aesthetics of the automotive interior parts, and the failure to achieve the expected molding quality. To address this, the present invention proposes a combing component 5, which is used to comb the fibers on the automotive interior parts before molding, so that the fibers are arranged in a consistent direction.

[0058] In one embodiment of the present invention, the combing member 5 includes a plurality of spaced combing teeth 51. The combing member 5 is fixed on the frame 21 and moves with the lower mold 24 to comb the fuzz on the surface of the automotive interior parts in a directional manner.

[0059] Specifically, refer to the instruction manual appendix. Figure 6 and Figure 7 A combing component 5 is fixedly installed on the frame 21. The combing component 5 includes multiple combing teeth 51, and there is a gap between two adjacent combing teeth 51. The combing component 5 combs the fuzz on the top of the automotive interior parts through the multiple combing teeth 51.

[0060] Specifically, by fixing the combing component 5 on the frame 21, after the automotive interior parts are placed on the lower mold 24, the lower mold 24 is transported to the frame 21 by the feeding mechanism 4. The lower mold 24 drives the automotive interior parts to move synchronously. When passing through the combing component 5, the combing teeth 51 on the combing component 5 comb the hair on the surface of the automotive interior parts, combing the hair into a consistent direction. This solves the problem of hair being overfilled into the fine grooves of the mold due to messy hair, thereby improving the processing quality of the automotive interior parts.

[0061] In the above technical solution, the combing component 5 and the feeding mechanism 4 are used to comb the surface fuzz of the automotive interior parts to solve the problem of messy fuzz causing excessive filling of the fine grooves of the mold. However, for softer automotive interior parts, and when there are knots of fuzz on the surface of the automotive interior parts, it is easier for the combing component 5 to move the automotive interior parts when the combing teeth 51 come into contact with the knots of fuzz. This can cause the automotive interior parts to shift and wrinkle. If the automotive interior parts are shifted and wrinkles are caused, the automotive interior parts will be displaced, which will affect the molding quality of the automotive interior parts during molding. Furthermore, after the automotive interior parts are displaced, it will also affect the combing of the fuzz on the surface of the automotive interior parts. Therefore, this invention proposes a leveling mechanism 6 to flatten the automotive interior parts. After the automotive interior parts are flattened, the fuzz on the surface of the automotive interior parts is combed.

[0062] In one embodiment of the present invention, the leveling mechanism 6 is provided with at least four sets, each set including a power component 61, a slide 62 and a pressure plate 63, and the four sets of leveling mechanisms 6 move outward synchronously to clamp and tension the four edges of the automotive interior parts.

[0063] Specifically, refer to the instruction manual appendix. Figures 8 to 11 The lower mold 24 is provided with a leveling mechanism 6, which includes four sets of leveling mechanisms 6. The four sets of leveling mechanisms 6 can move away synchronously. The four sets of leveling mechanisms 6 can flatten and level the car interior parts by moving away synchronously. The leveling mechanism 6 includes a power component 61, which is installed on the lower mold 24. A slide block 62 is installed at the output end of the power component 61. The slide block 62 is slidably disposed in the lower mold 24. A pressure plate 63 is hinged on the slide block 62. An elastic element 64 is provided between the pressure plate 63 and the slide block 62. A limit plate 65 is fixedly disposed in the lower mold 24. One side of the limit plate 65 is in contact with the pressure plate 63. When the pressure plate 63 is at a horizontal height, the top height is lower than the bottom height of the limit plate 65.

[0064] In one embodiment of the present invention, an elastic element 64 is provided between the pressure plate 63 and the slide block 62, and a limiting plate 65 for limiting the flipping angle of the pressure plate 63 is provided in the lower mold 24.

[0065] Specifically, the power component 61 is a cylinder, and the elastic component 64 is a spring. After the automotive interior part is placed on the lower mold 24, the cylinder drives the slide 62 to move away from the lower mold 24. At this time, under the limiting action of the limiting plate 65, the pressure plate 63 can rotate. With the cooperation of the pressure plate 63 and the slide 62, one side of the automotive interior part is clamped and the spring is squeezed. Then, while the slide 62 moves, one side of the automotive interior part is pulled. Since the leveling mechanism 6 includes four sets, the four sets clamp the four sides of the automotive interior part respectively, and the four sides of the automotive interior part can be pulled at the same time. This can tighten and level the automotive interior part, thus solving the problem that the automotive interior part is shifted or wrinkled during the combing process due to the soft material or the knotted fuzz on the surface of the automotive interior part, which affects the processing quality.

[0066] Specifically, since the automotive interior parts have a certain thickness when clamping them, the top height of the pressure plate 63 needs to be lower than the bottom height of the limiting plate 65 when it is at a horizontal height, so as to ensure that the automotive interior parts are clamped and flattened.

[0067] In one embodiment of the present invention, the straightening mechanism 7 includes a rotatable top plate 71, a rotating shaft 72, and a power component 73. The power component 73 drives the top plate 71 to rotate the automotive interior parts, thereby achieving automatic straightening of the automotive interior parts.

[0068] In the above technical solution, although the leveling mechanism 6 can be used to level the automotive interior parts, when placing the automotive interior parts, manual operation is usually used to straighten them based on experience. At this time, after a long period of manual work, the placement of the automotive interior parts is easily misaligned, which will cause the pattern at the molding point to shift due to the misalignment of the automotive interior parts, thus affecting the processing quality. To this end, the present invention also provides a straightening mechanism 7, which is used to straighten the automotive interior parts when they are misaligned, so as to solve the problem that the processing quality is affected by the misalignment of the automotive interior parts during placement.

[0069] Specifically, refer to the instruction manual appendix. Figure 12 and Figure 13 The lower mold 24 is also equipped with a straightening mechanism 7, which includes a rotatable top plate 71 for supporting the placement of automotive interior parts. The straightening mechanism 7 straightens the automotive interior parts by rotating the top plate 71. The straightening mechanism 7 also includes a rotating shaft 72, which is rotatably mounted on the lower mold 24. The top plate 71 is fixedly connected to the rotating shaft 72. A power component 5 73 is mounted on the lower mold 24. A drive gear 74 is mounted on the output end of the power component 5 73. A driven gear 75 is fixedly mounted on the rotating shaft 72. The drive gear 74 and the driven gear 75 mesh with each other.

[0070] Specifically, the power component 73 is a motor. When the car interior parts are manually placed and the car interior parts are misaligned, the motor drives the drive gear 74 to rotate. Through the meshing of the drive gear 74 and the driven gear 75, the top plate 71 is rotated through the rotating shaft 72. Thus, the car interior parts are aligned and straightened. After alignment, the car interior parts are leveled and the surface lint is combed.

[0071] In one embodiment of the present invention, the punching equipment further includes a vision inspection device for identifying the placement position of automotive interior parts and feeding back a signal to the straightening mechanism.

[0072] Specifically, a visual inspection camera can be set up to detect whether the interior parts of the car are misaligned. The visual inspection camera can monitor the placement of the interior parts of the car in a timely manner and straighten them in a timely manner through the straightening mechanism 7.

[0073] In one embodiment of the present invention, the feeding mechanism 4 includes a power component 41 and a guide rail 44, which are used to drive the lower mold 24 to reciprocate on the machine body 1 to realize the feeding and unloading of automotive interior parts.

[0074] A processing method for a stamping device used in automotive interior trim processing includes the following steps:

[0075] Step 1: Automatically align the automotive interior parts placed on the lower mold 24;

[0076] Step 2: The automotive interior parts are clamped and tensioned by the leveling mechanism 6 to eliminate wrinkles;

[0077] Step 3: During the process of sending the lower die 24 into the punching station, the combing part 5 is used to comb the surface hair in a directional manner.

[0078] Step 4: The upper mold 23 and the lower mold 24 work together to complete the heated punching;

[0079] Step 5: After punching, the lower surface of the upper mold 23 is automatically cleaned by the movable rotating processing part 31 to remove the adhering lint.

[0080] Specifically, in step one, the automotive interior parts are placed on the top plate 71 on the lower mold 24. If there is a placement offset, the power component 73 in the straightening mechanism 7 drives the drive gear 74 and the driven gear 75 to mesh, thereby rotating the rotating shaft 72 and the top plate 71 to automatically straighten the automotive interior parts.

[0081] Specifically, in step two, the leveling mechanism 6 is activated, and the slide block 62 is driven outward by four sets of power components 61. Under the action of the limiting plate 65, the pressure plate 63 is flipped to clamp the edge of the car interior parts, and continues to be pulled to tension and level the car interior parts.

[0082] Specifically, in step three, the feeding mechanism 4 is started, and the connecting seat 42 is driven to move along the guide rail 44 through the power component 3 41, which drives the lower mold 24 to feed downwards to the frame 21, so that the automotive interior parts pass through the combing component 5 fixed on the frame 21 during the movement, and the surface hairs are combed in a directional manner by multiple combing teeth 51.

[0083] Specifically, in step four, after the lower mold 24 is in place, the drive component 22 is activated to drive the upper mold 23 to move downward, cooperating with the lower mold 24 to complete the punching, while the heating component 25 heats the automotive interior parts to assist in forming.

[0084] Specifically, in step five, after the blanking is completed, the drive component 22 drives the upper mold 23 to reset, and the fluff treatment mechanism 3 is started. The second power component 33 drives the lead screw 34 to rotate, which drives the vertical seat 35 to move laterally along the lower surface of the upper mold 23. At the same time, the first power component 32 drives the treatment component 31 to rotate, cleans the fluff adhering to the lower surface of the upper mold 23, and removes the debris through the air extraction component.

[0085] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
