Description

Technical Field

[0001] This solution belongs to the field of vehicle manufacturing technology, specifically involving a production device for automotive suspension brackets based on laser blanking. Background Technology

[0002] A vehicle mount is a vibration-damping connection assembly between the powertrain and the vehicle body or frame. It typically consists of elastic elements, damping elements, and a load-bearing structure. Its function is to buffer the vibrations and noise generated during powertrain operation, while also fixing the powertrain in position to ensure stable power transmission. The mount bracket is the load-bearing and mounting structure within the mount assembly. As the mounting carrier for the elastic and damping elements, it provides the assembly foundation for the entire mount through its connection to the vehicle body / frame and powertrain, directly affecting the mount's vibration damping effect, structural stability, and overall vehicle ride comfort.

[0003] See the existing publication (announcement) number CN103008460A, which discloses a method for manufacturing an automotive engine mounting bracket and a mold for manufacturing it. The mold includes an upper mold, a lower mold, and a base. The base is equipped with the lower mold and a guide post. The upper mold is mounted on the guide post and moves up and down along the guide post. A die is mounted on the upper mold, and a punch is mounted on the lower mold. It also includes an ejector block, which is connected to the base by multiple base springs. The ejector block has a cavity in the middle that mates with the punch. When the base springs are in a free state, the punch is entirely in the cavity. The upper surface of the ejector block corresponds to the shape of the lower surface of the die. When the upper mold is pressed down, it contacts and drives the ejector block to move downward, compressing the base springs and exposing the punch, so that the punch mates with the die.

[0004] For example, the manufacturing mold used for the aforementioned suspension bracket uses a punch and a die to gradually engage, pressing the blank block into shape throughout the pressing process. However, during the stamping process, the base spring on which the ejector block relies is prone to fatigue after long-term use, leading to insufficient stability in the movement of the ejector block. This can cause misalignment between the upper and lower dies, resulting in misalignment of the punch and die. Utility Model Content

[0005] The purpose of this solution is to provide a laser blanking-based automotive mounting bracket production device to solve the production problems of automotive mounting brackets.

[0006] To achieve the above objectives, this solution provides a laser blanking-based automotive mounting bracket production apparatus, comprising: A conveying device is used to transfer workpieces, and the conveying device is equipped with a laser sensor for detecting the workpiece's arrival at the designated position. A blanking device is located at the rear end of the conveying device and is used for stamping and separating workpieces. The first stamping device is located at the rear end of the blanking device and is used to stamp the workpiece into a horizontal surface. The second stamping device is located at the rear end of the first stamping device and is used to stamp the horizontal surface into an inclined slope. The third stamping device is located at the rear end of the second stamping device and is used to stamp the side of the workpiece to form an irregular surface. A fourth stamping device is located at the rear end of the third stamping device, and the fourth stamping device is used to stamp a horizontal surface to form an assembly hole.

[0007] The principle and effect of this scheme are as follows: (1) The workpiece is transferred by the conveying device and the workpiece is detected by the laser sensor to provide positioning for subsequent processes, avoiding processing deviation caused by workpiece offset. Then the workpiece is stamped and separated by the blanking device. Then the horizontal surface, inclined surface, irregular surface and assembly hole are formed step by step by the first to fourth stamping devices. The stress concentration and dimensional error generated by single forming can be reduced by step processing, and the quality of the suspension frame can be improved. (2) This scheme changes the traditional blanking method. By laser blanking, the workpiece is positioned by the laser sensor of the conveying device, and the protrusion and blanking groove structure in the blanking device that match the size of the workpiece can reduce the excess processing allowance reserved by the traditional punching to avoid burrs and chipping. It avoids the waste caused by unreasonable arrangement and excessive allowance of raw materials, improves the utilization rate of raw materials and reduces the production material cost.

[0008] Furthermore, the blanking device includes a blanking upper die and a blanking lower die. The blanking upper die is movably disposed above the blanking lower die, and the blanking upper die and the blanking lower die are connected by a guide post, so that the first stamping upper die can move along the guide post toward the first stamping lower die. The blanking upper die is connected to a blanking die head for punching the workpiece, and the blanking upper die is connected to a drive source for driving the blanking upper die.

[0009] The principle and effect of this solution are as follows: the upper blanking die is driven to move along the guide post towards the lower blanking die by the power provided by the drive source, and the workpiece is punched and separated by the blanking die head.

[0010] Furthermore, the blanking die head has a protrusion on the side near the blanking lower die that matches the workpiece, and the size of the protrusion matches the size of the workpiece; the blanking lower die has a blanking groove that matches the protrusion, and the size of the blanking groove matches the size of the protrusion.

[0011] The principle and effect of this solution are as follows: by setting a protrusion that matches the size of the workpiece, and by setting a blanking groove on the blanking die that matches the size of the protrusion, a concave-convex fit structure is formed during the punching process, thereby positioning and defining the contour of the workpiece, preventing the workpiece from shifting or deforming during punching, and by punching in accordance with the shape of the workpiece, the contour size of the workpiece after punching is more regular, reducing burrs, chipping, etc.

[0012] Furthermore, the first stamping device includes a first upper stamping die and a first lower stamping die. The first upper stamping die is movably disposed above the first lower stamping die, and the first upper stamping die and the first lower stamping die are connected by a guide post, so that the first upper stamping die moves along the guide post toward the first lower stamping die. The first upper stamping die is connected to a first upper stamping die head for punching the workpiece, and the first upper stamping die is connected to a drive source for driving the first upper stamping die. The first lower stamping die is connected to a first lower stamping die head that cooperates with the first upper stamping die head.

[0013] The principle and effect of this solution are as follows: the power source provides power to drive the first upper stamping die to move along the guide post towards the first lower stamping die, and the first upper stamping die head and the first lower stamping die head cooperate to perform punching and cutting on the workpiece, so as to reduce processing defects such as edge burrs and dimensional deviations.

[0014] Furthermore, the punching surfaces of the first upper stamping die and the first lower stamping die both include a horizontal stamping surface and a symmetrical inclined stamping surface, which are used to stamp the workpiece into a horizontal surface.

[0015] The principle and effect of this solution are as follows: the first upper stamping die and the first lower stamping die directly apply stamping to the target forming area of ​​the workpiece through the horizontal stamping surface. The symmetrically set inclined stamping surfaces realize the stable positioning of the workpiece and disperse the stamping stress, avoiding deformation problems such as warping and displacement of the workpiece during the stamping process, and improving the flatness and dimensional accuracy of the horizontal surface after forming.

[0016] Furthermore, the second stamping device includes a second upper stamping die and a second lower stamping die. The second upper stamping die is movably disposed above the second lower stamping die, and the second upper stamping die and the second lower stamping die are connected by a guide post, so that the second upper stamping die moves along the guide post toward the second lower stamping die. The second upper stamping die is connected to a second upper stamping die head for stamping a horizontal surface into an inclined surface, and the second upper stamping die is connected to a drive source for driving the second upper stamping die. The second lower stamping die is connected to a second lower stamping die head that cooperates with the second upper stamping die head. The second upper stamping die head includes a punching conical surface, and the second lower stamping die head is provided with a punching groove that cooperates with the punching conical surface.

[0017] The principle and effect of this solution are as follows: the second upper stamping die is driven by the drive source to move along the guide post to the second lower stamping die. The punching cone surface of the second upper stamping die and the punching groove of the second lower stamping die form a matching stamping structure, which presses the already formed horizontal surface of the workpiece into a slope at a preset angle. At the same time, the fit between the punching cone surface and the punching groove can evenly distribute the stamping stress and reduce the deformation of the workpiece caused by excessive local stress.

[0018] Furthermore, the third stamping device includes a third upper stamping die and a third lower stamping die. The third upper stamping die is movably disposed above the third lower stamping die, and the third upper stamping die and the third lower stamping die are connected by a guide post, so that the third upper stamping die can move along the guide post towards the third lower stamping die. The third upper stamping die is connected to a third upper stamping die head for stamping the side of the workpiece to form an irregular surface, and the third upper stamping die is connected to a drive source for driving the third upper stamping die. The third lower stamping die is connected to a third lower stamping die head that cooperates with the third upper stamping die head.

[0019] The principle and effect of this solution are as follows: the drive source drives the third upper stamping die to move along the guide post to the third lower stamping die. The matching structure of the upper and lower stamping dies is used to perform targeted stamping on the side of the workpiece. The positioning function of the guide post can avoid misalignment of the irregular surface contour caused by the misalignment of the upper and lower dies. The upper and lower dies can fit the irregular structure requirements of the side of the workpiece and transmit the force evenly during the stamping process. This ensures that the side is pressed into the preset irregular surface shape and reduces wrinkles or cracks caused by uneven local stress.

[0020] Furthermore, the third upper stamping die is provided with a receiving groove for accommodating the workpiece, and the side of the receiving groove is provided with a shaped punching surface, which matches the side of the workpiece; the third lower stamping die is provided with a shaped groove that matches the receiving groove.

[0021] The principle and effect of this solution are as follows: the workpiece is accommodated and limited by the receiving groove of the third stamping upper die head, and the irregular punching surface that matches the side of the workpiece is used to form a complete stamping cavity with the irregular groove of the third stamping lower die head. During the stamping process, the workpiece is constrained to avoid displacement or deformation, and the stamping force is transmitted through the fit between the irregular punching surface and the groove, so that the side of the workpiece is pressed into the preset irregular surface shape.

[0022] Furthermore, the fourth stamping device includes a fourth upper stamping die and a fourth lower stamping die. The fourth upper stamping die is movably disposed above the fourth lower stamping die via a guide post, allowing the fourth upper stamping die to move along the guide post toward the fourth lower stamping die. The fourth upper stamping die is connected to a fourth upper stamping die head for stamping an assembly hole in a horizontal surface. The fourth upper stamping die is also connected to a drive source for driving the fourth upper stamping die. The fourth lower stamping die is connected to a fourth lower stamping die head that cooperates with the fourth upper stamping die head.

[0023] The principle and effect of this solution are as follows: the drive source drives the fourth upper stamping die to move along the guide post to the fourth lower stamping die, and the cooperation between the upper and lower stamping dies punches holes in the horizontal surface of the workpiece.

[0024] Furthermore, the fourth upper stamping die is provided with a punching head, and the number of punching heads is four symmetrically arranged; the fourth lower stamping die is provided with a boss that cooperates with the punching head, and the boss is used to support the inclined surface; the fourth lower stamping die is provided with a slot for holding and fixing the edge of the irregular surface.

[0025] The principle and effect of this solution are as follows: the four symmetrical punching heads of the fourth upper punching die can simultaneously punch the horizontal surface of the workpiece. The boss of the fourth lower punching die forms a stable bearing on the inclined surface of the workpiece, and the slot holds and fixes the edge of the irregular surface. During the punching process, the punching heads ensure the positional symmetry and diameter accuracy of the four assembly holes. Furthermore, the cooperation between the boss and the slot prevents the workpiece from shifting or deforming due to the punching force, so that the material around the hole is subjected to uniform force, reducing burrs and hole position deviations.

Detailed Implementation

[0028] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example: Please see Figures 1-17This embodiment discloses a laser-based automotive suspension bracket production device. Along the processing flow of workpiece 5, a conveying device, a blanking device 1, a first stamping device 2, a second stamping device 3, a third stamping device 4, and a fourth stamping device 6 are sequentially arranged. Each device is fixedly installed on the same cast iron worktable via steel brackets to meet the continuous processing requirements of mass production of suspension brackets. The conveying device is existing technology, employing a synchronous belt conveyor structure (not shown). The feed end of the conveying device is connected to the upstream coil uncoiling equipment via a flange, and the discharge end is precisely aligned with the feed area of ​​the blanking device 1. Laser sensors (not shown) are fixedly installed on the steel brackets on both sides of the conveying device via angle brackets. The laser sensors are diffuse reflection photoelectric sensors, with their detection probe axis set at a 90° angle perpendicular to the synchronous belt surface. The signal output end of the laser sensor is electrically connected to the signal input end of the device's overall control system via a shielded wire. When workpiece 5 moves to the preset processing position of unloading device 1 along the synchronous belt, the beam emitted by the laser sensor is reflected and received by the next workpiece 5, and then sends a workpiece 5 arrival signal to the main control system. The main control system immediately controls the drive motor of the conveyor to stop running, and at the same time triggers the unloading device 1 to start, so as to avoid subsequent processing deviations caused by workpiece 5 shifting due to positioning.

[0029] Please see Figure 1 and Figure 2The blanking die 12 of the blanking device 1 is fixedly installed on the worktable by bolts. Guide posts are vertically welded at the four corners of the upper surface of the blanking die 12. Guide holes are opened at the four corners of the blanking die 11 corresponding to the guide posts. The guide holes and guide posts are clearance-fitted to allow the blanking die 11 to move smoothly and center along the guide posts. The top center of the blanking die 11 is fixedly connected to the drive source. In this embodiment, the drive source is a double-acting hydraulic drive cylinder (not shown). The cylinder body of the hydraulic drive cylinder is fixedly installed on the top crossbeam bracket (not shown) by bolts. The lower surface of the blanking die 11 is fixedly connected to the blanking die head 14 by bolts. The blanking die head 14 is made of mold steel. A protrusion 141 is integrally formed on the side of the blanking die head 14 near the blanking die 12. The outline of the protrusion 141 is completely consistent with the outline of the workpiece 5. The edge of the protrusion 141 is rounded with a radius of 0.2×45° to avoid scratching the workpiece 5 during punching. The upper surface of the blanking die 12 has a blanking groove 15 corresponding to the position of the protrusion 141. The depth of the blanking groove 15 is 2.5mm greater than the height of the protrusion 141. The inner wall contour of the blanking groove 15 fits snugly with the outer wall contour of the protrusion 141. A waste discharge hole is provided at the bottom of the blanking groove 15. During operation, the hydraulic drive cylinder drives the blanking upper die 11 to move downward along the guide post. The protrusion 141 gradually embeds into the blanking groove 15. Through the convex-concave mating structure, the workpiece 5 is accurately positioned and its contour is defined, avoiding displacement or deformation of the workpiece 5 during punching. At the same time, with the punching action that fits the shape of the workpiece 5, the contour dimensions of the workpiece 5 after punching are accurate, reducing processing defects such as burrs and chipping, and providing qualified blanks for subsequent stamping processes.

[0030] Please see Figures 3-8The first stamping die 22 of the first stamping device 2 is fixed to the worktable by bolts. Guide posts of the same specifications as those of the blanking device 1 are vertically welded to the four corners of the upper surface of the first stamping die 22. Guide holes are correspondingly provided at the four corners of the first stamping die 21, which cooperate with the guide posts to achieve movement. A double-acting hydraulic drive cylinder is also connected to the top of the first stamping die 21, and the parameters of the hydraulic drive cylinder are consistent with the drive source of the blanking device 1. The first stamping die head 23 is fixedly installed on the lower surface of the first stamping die 21 by bolts. The first stamping die head 24 is fixedly installed on the upper surface of the first stamping die 22 at the position corresponding to the first stamping die head 23 by bolts. Both the first stamping die head 23 and the first stamping die head 24 are made of mold steel. Both the upper stamping die 23 and the lower stamping die 24 have horizontal stamping surfaces 25 and symmetrical inclined stamping surfaces 26 on their cutting surfaces. The angle between the symmetrical inclined stamping surfaces 26 and the horizontal stamping surfaces 25 is set to 20°, and the inclined stamping surfaces 26 on both sides are symmetrically distributed about the center line of the horizontal stamping surfaces 25. During operation, the hydraulic drive cylinder drives the upper stamping die 21 to move along the guide post towards the lower stamping die 22. The horizontal stamping surfaces 25 directly apply a uniform stamping force to the target forming area of ​​the workpiece 5, while the symmetrical inclined stamping surfaces 26 provide stable positioning from both sides of the workpiece 5 and disperse the concentrated stress generated during the stamping process, avoiding deformation problems such as warping and displacement of the workpiece 5. Finally, the workpiece 5 is pressed into a preset horizontal surface 51, providing a flat reference for the subsequent processing of the inclined surface 52.

[0031] Please see Figures 9-11The second stamping die 32 of the second stamping device 3 is fixed to the worktable by bolts. The guide posts on the second stamping die 32 are exactly the same as the guide posts of the first stamping device 2. The four corners of the second stamping die 31 are provided with guide holes, and the top is connected to a double-acting hydraulic drive cylinder. The stamping force of the hydraulic drive cylinder is adjusted to 20-30kN according to the forming requirements of the inclined plane 52. The lower surface of the second stamping die 31 is fixedly installed with the second stamping die head 33 by internal bolts. The lower end of the second stamping die head 33 is machined with a punching cone surface 331. The cone angle of the punching cone surface 331 is designed to be 45° according to the angle of the preset inclined plane 52. The upper surface of the second stamping die 32 is fixedly mounted to the second stamping die 34 via bolts, corresponding to the position of the second stamping upper die 33. The upper surface of the second stamping die 34 has a punching groove 341. The inner wall of the punching groove 341 is a conical surface adapted to the punching cone surface 331. The depth of the punching groove 341 is 1mm greater than the height of the inclined surface 52 after forming, ensuring the complete forming of the inclined surface 52. During operation, the hydraulic drive cylinder drives the second stamping die 31 to move downwards along the guide post. The punching cone surface 331 gradually embeds into the punching groove 341, contacting and applying pressure to the already formed horizontal surface 51 of the workpiece 5. Through the conical surface mating structure, the horizontal surface 51 is pressed into an inclined surface 52 at a preset angle. Simultaneously, the close fit between the punching cone surface 331 and the punching groove 341 evenly distributes the stamping stress, reducing plastic deformation of the workpiece 5 caused by excessive local stress.

[0032] Please see 12- Figure 14The third stamping die 42 of the third stamping device 4 is fixed to the worktable by bolts, and the guide post on the third stamping die 42 is consistent with the specifications of the aforementioned device. The top of the third stamping die 41 is connected to a double-acting hydraulic drive cylinder, which outputs a stamping force of 35-45kN according to the forming requirements of the irregular surface 53. The lower surface of the third stamping die 41 is fixedly installed with the third stamping die head 43 by internal bolts. The lower part of the third stamping die head 43 is provided with a receiving groove 431. The inner diameter of the receiving groove 431 is 0.08mm larger than the outer diameter of the workpiece 5, which just accommodates the workpiece 5 and avoids positioning deviation caused by excessive gap. The inner wall of the receiving groove 431 is machined into an irregular punching surface 432, and the contour shape of the irregular punching surface 432 is completely consistent with the contour of the pre-set irregular surface 53 of the workpiece 5. The upper surface of the third stamping die 42 is fixedly mounted to the third stamping die head 44 by bolts at the position corresponding to the receiving groove 431. The upper surface of the third stamping die head 44 has an integrally formed irregular groove 441. The contour of the irregular groove 441 fits snugly with the irregular punching surface 432 of the receiving groove 431, and the two together form a complete stamping cavity. During operation, the hydraulic drive cylinder drives the third stamping die 41 to move downward along the guide post. The workpiece 5 is wrapped by the receiving groove 431 to achieve limitation. The irregular punching surface 432 cooperates with the irregular groove 441 to apply a uniform stamping force to the side of the workpiece 5. While constraining the workpiece 5 to avoid displacement or deformation, the side of the workpiece 5 is pressed into the preset irregular surface 53 shape.

[0033] Please see Figures 15-17The fourth stamping die 62 of the fourth stamping device 6 is fixed to the worktable by bolts, and the guide post on the fourth stamping die 62 is consistent with the specifications of the aforementioned device. The top of the fourth stamping upper die 61 is connected to a double-acting hydraulic drive cylinder, which outputs a stamping force of 15-25kN according to the punching requirements of the assembly hole 54. The lower surface of the fourth stamping upper die 61 is fixedly installed with the fourth stamping upper die head 63 by internal bolts. The lower end of the fourth stamping upper die head 63 has four punching heads 631 integrally formed. The four punching heads 631 are symmetrically arranged at 90° along the central axis of the fourth stamping upper die head 63. The outer diameter of the punching head 631 is consistent with the inner diameter of the assembly hole 54, and the cutting edge of the punching head 631 has a sharp angle of 0.1×30°. The upper surface of the fourth stamping die 62 is fixedly mounted with the fourth stamping die head 64 by bolts. The upper surface of the fourth stamping die head 64 has a through hole corresponding to the position of the cutting head 631, which is adapted to the cutting head 631. The diameter of the through hole is 0.01 mm larger than the outer diameter of the cutting head 631. A waste collection groove is threadedly connected below the through hole. The upper surface of the fourth stamping die head 64 also has an integrally formed boss 641. The height of the boss 641 matches the inclination height of the inclined surface 52. When the workpiece 5 is placed on the fourth stamping die head 64, the boss 641 and the inclined surface 52 are completely fitted together to achieve stable load bearing. A slot 642 is provided at the edge of the fourth stamping die head 64. The inner contour of the slot 642 fits the edge contour of the irregular surface 53, which can clamp and fix the edge of the irregular surface 53. During operation, the hydraulic drive cylinder drives the fourth stamping upper die 61 to move downward along the guide post. The four punching heads 631 simultaneously punch the horizontal surface 51 of the workpiece 5. At the same time, the boss 641 supports the inclined surface 52, and the slot 642 fixes the edge of the irregular surface 53. The three work together to prevent the workpiece 5 from shifting or deforming due to the stamping force, so that the material around the hole is subjected to uniform force. This ensures the positional symmetry, hole diameter accuracy, and hole position deviation of the four assembly holes 54, and ensures that the assembled holes 54 after forming can adapt to the connection requirements of the suspension frame and other components.

[0034] When this device is working, the main control system operates according to a preset program: the conveying device transfers the blank to be processed to the blanking device 1. After the laser sensor detects that the workpiece 5 is in place, the conveying device stops, and the blanking device 1 starts to complete the punching and separation of the workpiece 5. Then the conveying device restarts and transfers the workpiece 5 to the first stamping device 2. The first stamping device 2 starts to press the workpiece 5 into a horizontal surface 51. Then the workpiece 5 is transferred to the second stamping device 3 and the third stamping device 4 in sequence to complete the forming of the inclined surface 52 and the irregular surface 53, respectively. Finally, the workpiece 5 is transferred to the fourth stamping device 6 to complete the synchronous punching of the four assembly holes 54. After each process is completed, the conveying device transfers the finished product to the downstream collection conveyor belt.
