Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more particularly to a local temperature-controlled stamping die based on a high-resilience material. Background Technology

[0002] In the automotive parts manufacturing industry, high-resilience materials (such as high-strength steel and aluminum alloys) are widely used in the production of key components such as stamped door anti-collision beams and engine hood outer panels due to their excellent performance. However, if the elastic deformation of such materials is not fully released during the stamping process, the dimensions of the parts will often deviate from the die surface after stamping. The amount of springback is positively correlated with the yield strength, thickness and bending radius of the material. That is, the higher the yield strength, the greater the thickness and the greater the bending radius, the greater the amount of springback. This poses a great challenge to the dimensional accuracy control of the parts after forming.

[0003] However, when stamping sheet materials using traditional stamping dies, such as the stamping die and stamping process for automotive parts disclosed in CN117299923A, the plastic deformation of the sheet material is achieved by the rigid clamping of the upper and lower dies. Although this processing method can produce stamping deformation of the sheet material, it lacks an effective mechanism to prevent springback after stamping. Especially for high-strength steel, aluminum alloys and other high-springback materials, the springback phenomenon after processing is almost unavoidable, which seriously affects the dimensional accuracy of the formed product and leads to an increase in the product defect rate. Furthermore, it is impossible to self-inspect sheet metal with surface defects (such as scratches, dents, etc.) before stamping, which means that sheet metal with unqualified surfaces will be stamped together during stamping, reducing the actual service life of the mold. Moreover, when unqualified products are detected later, the entire production process needs to be traced and investigated.

[0004] To address the aforementioned technical deficiencies, this application utilizes self-inspection during the automated feeding process, combined with temperature control and rapid cooling technology, to achieve rapid anti-springback stamping of high-resilience materials with qualified surfaces, thereby meeting the requirements of high-quality stamping production. Summary of the Invention

[0005] The purpose of this invention is to provide a locally temperature-controlled stamping die based on a high-resilience material to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a local temperature-controlled stamping die based on high-resilience material, including a double-row synchronous belt conveyor, wherein a dual-station forming component for moving temperature-controlled stamping of high-resilience sheet is provided on one side of the double-row synchronous belt conveyor, and a flipping component for double-sided self-inspection and feeding of high-resilience sheet is provided between the double-row synchronous belt conveyor and the dual-station forming component.

[0007] Preferably, multiple suction cups are installed at equal intervals on both sets of synchronous belts of the double-row synchronous belt conveyor.

[0008] Preferably, the dual-station forming assembly includes a U-shaped mounting base, with a first slide and a second slide slidably mounted on the top and inside of the mounting base, respectively, and a lifting seat provided on the top of the second slide. A fixed mold is fixedly mounted on the top of both the first slide and the lifting seat, and a movable mold adapted to the fixed mold is provided on the top of the fixed mold.

[0009] Preferably, the lifting seat is welded with a U-shaped block and a plurality of guide rods that are slidably connected to the second slide. A roller is rotatably mounted on the U-shaped block. A guide seat is fixedly connected to the bottom of the mounting seat, and the guide seat has a first guide groove that cooperates with the roller to raise and lower the lifting seat.

[0010] Preferably, the top of the first slide and the lifting seat are both fixedly connected with a plurality of limiting rods that are slidably connected to the corresponding moving mold. The first slide is slidably connected with a guide plate that is fixedly connected to the corresponding moving mold, and a guide wheel is rotatably mounted on the guide plate. The inner wall of the mounting seat is provided with a second guide groove that cooperates with the guide wheel to raise and lower the guide plate.

[0011] Preferably, gears are rotatably connected to both sides of the lifting seat, and toothed plates that mesh with the gears are installed on both the second slide and the moving mold. The fixed mold and the moving mold are respectively an inner concave mold and an outer convex mold.

[0012] Preferably, four sets of sprockets arranged in a rectangular array are rotatably mounted on one inner wall of the mounting base, and the sprockets are connected by chain drive. The first slide and the second slide are fixedly connected by a connecting block and a chain. A third servo motor that drives the corresponding sprockets to rotate is mounted on the mounting base.

[0013] Preferably, an electric heating rod is installed inside the moving mold, multiple cooling chambers are equidistantly arranged inside the fixed mold, and a connecting groove is provided between the tops of the cooling chambers. Connecting pipes communicating with the corresponding cooling chambers are installed on both sides of the fixed mold, and a control panel is installed on the mounting base.

[0014] Preferably, the flipping assembly includes a mounting bracket welded to a mounting base, and a rotating rod is rotatably connected between the mounting brackets. A C-shaped plate is symmetrically fixed to both sides of the rotating rod, and slots are provided on the inner walls of both sides of the C-shaped plate. An I-shaped pusher is slidably connected between the two sets of C-shaped plates, and a first servo motor that drives the rotating rod to rotate is mounted on the mounting bracket.

[0015] Preferably, a lead screw is rotatably mounted on the mounting frame, and a U-shaped plate that is slidably connected to the mounting frame is threaded onto the lead screw. Linear scan cameras are mounted on the inner walls of both sides of the U-shaped plate, and a second servo motor that drives the lead screw to rotate is mounted on the mounting frame.

[0016] The beneficial effects of this invention are as follows: This invention utilizes a dual-station forming assembly with alternating reverse motion to achieve mobile stamping forming of high-resilience sheet materials. This significantly improves stamping forming efficiency. During the movement process, the moving and stationary dies undergo autonomous rigid mold closing, reducing the need for additional drive components and lowering equipment production costs. Furthermore, during the mold closing stamping process, the moving die is first heated by an electric heating rod to indirectly soften the bent portion of the high-resilience sheet material. Then, coolant flows within the cooling chamber for rapid cooling and hardening. This process of heating and softening followed by cooling and hardening effectively reduces the material's yield strength and significantly minimizes elastic recovery, thereby improving the dimensional accuracy of the stamped product. This invention also utilizes a double-row synchronous belt conveyor and several suction cups on the synchronous belt combined with a flipping U-shaped plate. This not only enables automatic feeding of high-resilience sheet materials through flipping, assisting in automated stamping processing, but also allows a line scan camera to perform a full-range scan of both sides of the high-resilience sheet material using the flipping operation in conjunction with the moving U-shaped plate. This generates high-resolution two-dimensional image data, which is then analyzed in depth by the image analysis and comparison module in the control panel. This accurately identifies significant defects such as scratches and dents, enabling surface self-inspection of the high-resilience sheet material before stamping. This effectively prevents substandard high-resilience sheet materials from entering the stamping process, thus avoiding impacts on processing quality and efficiency. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 , Figures 4-9 As shown, given the lack of an effective mechanism in existing technologies to prevent springback after stamping, the problem of increased product defect rates due to springback after processing high-springback materials such as high-strength steel and aluminum alloys can be solved by the following solutions: The local temperature-controlled stamping die based on high-resilience material in this embodiment includes a double-row synchronous belt conveyor 1. A dual-station forming component 2 for moving and temperature-controlled stamping of high-resilience sheet material is provided on one side of the double-row synchronous belt conveyor 1. Through the alternating reverse movement of the dual-station forming component 2, the high-resilience sheet material is subjected to moving stamping and forming, which significantly improves the stamping and forming efficiency. At the same time, autonomous rigid mold closing is performed during the movement to reduce the use of additional driving components and reduce equipment production costs. A flipping component 3 for double-sided self-inspection and feeding of high-resilience sheet material is provided between the double-row synchronous belt conveyor 1 and the dual-station forming component 2.

[0021] The dual-station molding assembly 2 includes a U-shaped mounting base 21, with a first slide block 22 and a second slide block 23 slidably mounted on the top and inside of the mounting base 21, respectively. The first slide block 22 and the second slide block 23 are mounted at different heights to avoid mutual interference of reverse movements. A lifting seat 24 is provided on the top of the second slide block 23. A fixed mold 25 is fixedly mounted on the top of both the first slide block 22 and the lifting seat 24. A movable mold 26 that is adapted to the fixed mold 25 is provided on the top of the fixed mold 25.

[0022] The lifting seat 24 is welded with a U-shaped block 27 and multiple guide rods that are slidably connected to the second slide 23. A roller 28 is rotatably mounted on the U-shaped block 27. A guide seat 29 is fixedly connected to the bottom of the mounting seat 21. The guide seat 29 is provided with a first guide groove 210 that cooperates with the roller 28 to lift the lifting seat 24. When the second slide block 23 carries the lifting seat 24 from one side of the mounting base 21 to the other side, the first guide groove 210 guides the roller 28, causing the lifting seat 24 to first descend, move horizontally, and then rise. This enables the fixed mold 25 and the moving mold 26 on the lifting seat 24 to sink and move in the middle of the mounting base 21, thus achieving material loading and unloading at both sides while avoiding interference with the movement of the first slide block 22.

[0023] The top of the first slide block 22 and the lifting seat 24 are both fixedly connected with multiple limiting rods that are slidably connected to the corresponding moving mold 26. These rods are used to achieve stable lifting and lowering of the moving mold 26 and to prevent the fixed mold 25 and the moving mold 26 from deviating during mold closing. The first slide block 22 is slidably connected with a guide plate 211 that is fixedly connected to the corresponding moving mold 26. A guide wheel 212 is rotatably mounted on the guide plate 211. The inner wall of the mounting seat 21 is provided with a second guide groove 213 that cooperates with the guide wheel 212 to lift and lower the guide plate 211. When the first slide block 22 slides from one side of the mounting base 21 to the other side, the guide wheel 212 is guided by the second guide groove 213, causing the corresponding moving mold 26 to move down autonomously to close the mold fixed mold 25, and perform continuous mold closing movement to rigidly stamp and form the high-resilience sheet material. Then, the moving mold 26 is pushed up to reset, in order to assist in the unloading of the formed high-resilience sheet material.

[0024] Gears 214 are rotatably connected to both sides of the lifting seat 24. The second slide 23 and the moving mold 26 are both equipped with toothed plates 215 that mesh with the gears 214. The side of the toothed plate 215 away from the teeth is slidably connected to the lifting seat 24, thereby assisting in restricting the effective meshing of the toothed plate 215 and the gears 214. The fixed mold 25 and the moving mold 26 are respectively the inner concave mold and the outer convex mold. The lifting seat 24 carries the gear 214 in a downward movement. The gear plate 215 meshes with the gear plates 215 on both sides, causing the gear 214 to rotate. This, in turn, drives the fixed mold 25 on the lifting seat 24 to descend and rigidly close with the moving mold 26 through the upper gear plate 215. This continues until the second slide 23 moves to the other side of the mounting seat 21. The first guide groove 210 guides the roller 28 to make the lifting seat 24 rise, and the fixed mold 25 and the moving mold 26 separate.

[0025] Four sets of sprockets arranged in a rectangular array are rotatably mounted on one inner wall of the mounting base 21, and the sprockets are connected by chain drive. The first slide 22 and the second slide 23 are fixedly connected by a connecting block and a chain. A third servo motor is mounted on the mounting base 21 to drive the corresponding sprocket to rotate. The third servo motor drives the corresponding sprocket to rotate, and the chain drives the first slide 22 and the second slide 23 to move relative to each other or away from each other.

[0026] An electric heating rod 216 is installed inside the moving mold 26. The electric heating rod 216 is installed at the position where the sheet material deforms, and performs localized temperature control and independent heating and softening treatment according to the amount of springback to avoid affecting the overall quality. The amount of springback is obtained by stamping at room temperature, so that multiple electric heating rods 216 can be controlled to heat to a specified temperature through the temperature control module in the control panel to perform localized heating treatment on the moving mold 26, thereby performing localized temperature control and softening treatment on the bent part of the high springback sheet material, reducing the yield strength of the material and reducing elastic recovery. Multiple cooling chambers 217 are equidistantly arranged inside the fixed mold 25, and a connecting groove is provided between the tops of the cooling chambers 217. Connecting pipes connected to the corresponding cooling chambers 217 are installed on both sides of the fixed mold 25. After heating and softening, a control signal is generated by the controller in the control panel to control the external water pump to draw coolant in conjunction with the pipes connected to the connecting pipes and the connecting grooves between the tops of the cooling chambers 217. The coolant is injected into the multiple cooling chambers 217 of the fixed mold 25 to cool, harden and shape the high-resilience sheet material after stamping, further reducing the springback of the high-resilience sheet material. A control panel is installed on the mounting base 21. The control panel is equipped with a controller, an image analysis and comparison module and a temperature control module.

[0027] Example 2: Please refer to Figures 1-3 As shown, the problem of not being able to perform self-inspection of sheet metal with surface defects before stamping and to achieve automatic feeding to improve stamping efficiency can be solved by the following solutions: The local temperature-controlled stamping die based on high-resilience material in this embodiment includes a double-row synchronous belt conveyor 1. The double-row synchronous belt conveyor 1 can avoid interference with the rotation of the I-shaped plate 33 carrying the I-shaped pusher 34. A dual-station forming component 2 for moving temperature-controlled stamping of high-resilience sheet is provided on one side of the double-row synchronous belt conveyor 1. A flipping component 3 for double-sided self-inspection and feeding of high-resilience sheet is provided between the double-row synchronous belt conveyor 1 and the dual-station forming component 2.

[0028] Multiple suction cups 11 are installed at equal intervals on both sets of synchronous belts of the double-row synchronous belt conveyor 1. When multiple high-resilience sheet materials are transported intermittently by the double-row synchronous belt conveyor 1, the high-resilience sheet materials are adsorbed and fixed by the multiple suction cups 11 on the synchronous belt to prevent deviation and slippage and transport them into the corresponding shaped plate 33.

[0029] The flipping assembly 3 includes a mounting bracket 31 welded to the mounting base 21, and a rotating rod 32 is rotatably connected between the mounting brackets 31. A C-shaped plate 33 is symmetrically fixed to both sides of the rotating rod 32, and slots are opened on the inner walls of both sides of the C-shaped plate 33. An I-shaped pusher 34 is slidably connected between the two sets of C-shaped plates 33. A first servo motor that drives the rotating rod 32 to rotate is installed on the mounting bracket 31. With the cooperation of the suction cup 11 on the synchronous belt, the high-resilience sheet material can be driven to push the I-shaped pusher 34 to move. Then, the movement of the I-shaped pusher 34 automatically and completely pushes out the high-resilience sheet material in the C-shaped plate 33 on the other side and falls into the inner cavity of the moving mold 26 to complete the feeding process.

[0030] A lead screw 35 is rotatably mounted on the mounting bracket 31, and a U-shaped plate 36 is threadedly connected to the lead screw 35 and slidably connected to the mounting bracket 31. Linear array cameras are mounted on the inner walls of both sides of the U-shaped plate 36. A second servo motor that drives the lead screw 35 to rotate is mounted on the mounting bracket 31. The high-resilience sheet material enters the slots between the U-shaped plates 33. The first servo motor drives the rotating rod 32 to rotate 90°, so that the high-resilience sheet material is located between the U-shaped plates 36. The second servo motor drives the lead screw 35 to rotate, causing the U-shaped plate 36 to carry two sets of line scan cameras to move on both sides of the high-resilience sheet material. The line scan cameras scan the surface of both sides of the high-resilience sheet material in all directions, generating high-resolution two-dimensional image data information. Combined with the image analysis and comparison module in the control panel, the two-dimensional image data information is analyzed in depth to accurately identify defects such as scratches and dents that have a significant impact. This enables the surface self-inspection treatment of the high-resilience sheet material before stamping, effectively preventing unqualified high-resilience sheet material from entering the stamping process and affecting processing quality and efficiency.

[0031] Example 3: Please refer to Figures 1-9 As shown, the present invention also proposes a method for using a locally temperature-controlled stamping die based on a high-resilience material, comprising the following steps: Step 1: Multiple high-resilience sheet materials are intermittently conveyed by a double-row synchronous belt conveyor 1. During the conveying process, the high-resilience sheet materials are adsorbed and fixed by multiple suction cups 11 on the synchronous belt to prevent deviation and slippage during conveying. Step 2: The high-resilience sheet material is adsorbed and conveyed to the slots between a set of U-shaped plates 33 by the double-row synchronous belt conveyor 1. The high-resilience sheet material moves against the I-shaped pusher 34. Then, the first servo motor drives the rotating rod 32 to rotate 90°, so that the high-resilience sheet material is located between the U-shaped plates 36. The second servo motor drives the lead screw 35 to rotate, which drives the U-shaped plates 36 to move on both sides of the high-resilience sheet material carrying two sets of line scan cameras. Step 3: The line scan camera simultaneously scans both sides of the high-resilience sheet material, generating high-resolution two-dimensional image data information and transmitting it to the image analysis and comparison module in the control panel. The image analysis and comparison module identifies defects such as scratches and dents based on the received two-dimensional image data information. If any of the following occurs: the length or depth of the scratch is greater than or equal to the preset length or depth, or the number of dents is greater than or equal to the set number, the surface of the high-resilience sheet material is determined to be unqualified. The image analysis and comparison module generates an unqualified signal and transmits it to the controller in the control panel to generate a first-level control signal, which controls the external robot to grab the unqualified high-resilience sheet material and move it to the waste collection area. Conversely, if the surface of the high-resilience sheet material is deemed qualified, the image analysis and comparison module generates a qualified signal and transmits it to the controller in the control panel to generate a secondary control signal, which controls the first servo motor to drive the rotating rod 32 to continue to deflect 90°. Step 4: The high-resilience sheet material is adsorbed and conveyed to the slots of another set of C-shaped plates 33 by the double-row synchronous belt conveyor 1. The high-resilience sheet material moves against the I-shaped pusher 34, thereby removing the qualified high-resilience sheet material from the corresponding C-shaped plate 33 and pushing it into the inner cavity of the fixed mold 25 on the first slide block 22. Then, multiple high-resilience sheet materials are continuously inspected and fed. Step 5: The third servo motor drives the corresponding sprocket to rotate, which in turn drives the first slide block 22 and the second slide block 23 to move relative to each other via the chain. During the movement of the first slide block 22, the guide wheel 212 is guided by the second guide groove 213, causing the corresponding moving mold 26 to move down and close. Together with the fixed mold 25, the high-resilience sheet material is rigidly stamped and formed. At the same time, the temperature control module in the control panel controls the electric heating rod 216 to heat to the specified temperature, which heats the moving mold 26. This allows for localized temperature-controlled heating and softening of the bent part of the high-resilience sheet material, reducing the yield strength of the material, reducing elastic recovery, and improving the dimensional accuracy after stamping and forming. After the heating process of the electric heating rod 216 is stopped, a control signal is generated by the controller in the control panel to control the external water pump to draw coolant and inject it into the multiple cooling chambers 217 of the fixed mold 25 through the pipe connected to the connecting pipe. This coolant is used to cool, harden and shape the high-resilience sheet material after stamping, further reducing the springback of the high-resilience sheet material. When the first slide 22 moves to the side of the mounting seat 21 away from the double-row synchronous belt conveyor 1, the guide wheel 212 is guided by the second guide groove 213, causing the corresponding moving mold 26 to rise and reset, assisting in the unloading of the high-resilience sheet material. Step Six: During the movement of the second slide block 23, the first guide groove 210 guides the roller 28, causing the lifting seat 24 to first descend, move horizontally, and then rise. During this process, the lifting seat 24 carries the gear 214 downward, and the gear 214 rotates due to the meshing of the toothed plate 215 with the toothed plate 215 below it. This causes the toothed plate 215 above the gear 214 to descend, causing the fixed mold 25 and the moving mold 26 on the lifting seat 24 to rigidly close. This continues until the second slide block 23 moves to the side of the mounting base 21 close to the double-row synchronous belt conveyor 1. The first guide groove 210 guides the roller 28, causing the lifting seat 24 to rise. The fixed mold 25 and the moving mold 26 separate, and the high-resilience sheet material is fed through the two sets of rotating C-shaped plates 33.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
