Description
Technical Field
[0001] This invention relates to the field of anti-collision beam forming mold technology, and in particular to an anti-collision beam punching-stretching-bending forming mold. Background Technology
[0002] Anti-collision beams are important structural components in automotive passive safety systems. They effectively absorb and disperse collision energy during a vehicle collision, thereby protecting the safety of occupants and reducing vehicle maintenance costs. In the manufacturing process of anti-collision beams, stamping and bending are key processing steps, and their forming quality directly affects the mechanical properties and service life of the anti-collision beams. Currently, the stamping and bending of anti-collision beams is usually completed using special molds in conjunction with a press. The blank is bent to a preset curvature through the closing action of the upper and lower molds.
[0003] However, in the existing stamping and bending forming process of anti-collision beams, the loading and unloading of workpieces mostly rely on manual labor. Before and after each stamping and bending process, operators need to manually place the anti-collision beam blank to be processed into the mold cavity, and then remove the finished product from the mold after forming. This manual loading and unloading method has obvious drawbacks: on the one hand, during the loading and unloading process, the operator's arm needs to frequently reach into the closed area between the upper and lower molds. The stamping equipment is under great pressure when it is working. Once the equipment is accidentally started or the operation is wrong, it is very easy to cause serious safety accidents such as the operator's hand being squeezed or crushed. On the other hand, the operation cycle of manual loading and unloading is limited by the operator's skill level and physical exertion, making it difficult to improve production efficiency.
[0004] Therefore, how to design a mold structure that can automatically load and unload materials during the stamping and bending process of anti-collision beams, so as to eliminate the safety hazards caused by manual operation and improve production efficiency, is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0005] The purpose of this invention is to provide a punching, stretching, and bending forming mold for anti-collision beams to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a punching and bending forming mold for a crash beam, comprising a base, a top seat fixed to the top of which is supported by a load-bearing plate, a hydraulic mechanism mounted on the top seat, and a lower mold mounted on the base; further comprising a support mechanism, which is slidably mounted on the top of the base, having two components symmetrical about the lower mold, for supporting and positioning both ends of the crash beam; a feeding mechanism, located on one side of the base, for storing the crash beam to be processed and feeding it to the lower mold; a receiving mechanism, located on the side of the base away from the feeding mechanism, for unloading and storing the processed crash beam; and a reset mechanism linked to the receiving mechanism and the feeding mechanism, the reset mechanism being used to push the crash beam on the feeding mechanism to ensure smooth operation of the hydraulic mechanism.
[0007] Preferably, it also includes a base plate, which is fixedly installed on the top of the base, a lower mold is fixedly installed in the middle position of the top of the base plate, and a support mechanism slides on the top of the base plate; a limiting slider is fixedly installed at the bottom of the support mechanism, the side of the limiting slider is convex, and the top of the base plate is provided with a limiting groove that matches the limiting slider. The limiting slider and the limiting groove cooperate to limit and guide the support mechanism.
[0008] Preferably, it also includes screw slots, which are formed on the top of the base plate. There are two of them, symmetrical about the lower mold. A drive screw is rotatably installed in each of the two screw slots. The threads of the two drive screws face opposite directions. The two drive screws are coaxially fixedly connected by a connecting shaft. A drive motor is fixedly installed on the top of the base. The output shaft of the drive motor is driven and connected to the outer end of one of the drive screws through a reducer. There are two drive sliders, which are threaded onto the outer surfaces of the two drive screws respectively. The tops of the two drive sliders are fixedly connected to the bottoms of the two support mechanisms respectively. When the drive motor rotates forward and reverse, it can simultaneously drive the two support mechanisms to move towards or away from each other. When the two support mechanisms move towards each other, they can simultaneously support and position both ends of the anti-collision beam. When the two support mechanisms move away from each other, they can simultaneously release the anti-collision beam.
[0009] Preferably, the hydraulic mechanism includes a hydraulic rod, a top plate, and an upper die; the cylinder of the hydraulic rod is fixedly installed on the top of the top seat, the telescopic rod of the hydraulic rod passes through the top seat and is fixedly connected to the top plate, the upper die is fixedly installed on the bottom of the top plate, and the upper die is located directly above the lower die; after the two support mechanisms support the anti-collision beam, the telescopic rod of the hydraulic rod extends and presses the anti-collision beam through the upper die, wherein the pressure can be increased by pressing down the top plate together.
[0010] Preferably, the feeding mechanism includes a storage rack, a push plate, and a stabilizing frame; the storage rack is L-shaped, one end of which is fixed to the top of the base and abuts against one side of the lower mold, the upper surface of the storage rack is flush with the top of the lower mold, the top of the stabilizing frame is fixed to the bottom of the storage rack away from the lower mold, and the bottom of the stabilizing frame is placed on the ground; the stabilizing frame supports the outer end of the storage rack, providing auxiliary load-bearing effect; the push plate slides on the top of the storage rack, and a guide rod is fixedly installed on one side of the push plate, which slides through the vertical section of the storage rack, and a pushing spring is provided between the push plate and the vertical section of the storage rack; when loading, the guide rod is first pulled to make the push plate close to the vertical section of the storage rack, and the anti-collision beam to be processed is placed on the storage rack, and the push plate pushes the anti-collision beam under the action of the pushing spring, pushing the anti-collision beam onto the lower mold.
[0011] Preferably, the two ends of the lower mold are protruding, and the top of the protrusion is flush with the upper surface of the storage rack. Both protruding tops are provided with recessed grooves. The width of the recessed grooves is equal to the width of the anti-collision beam. When the push plate pushes the anti-collision beam to slide to the top of the upper mold, the anti-collision beam will fall into the recessed groove under the action of gravity. The next anti-collision beam is blocked by the fallen anti-collision beam and cannot continue to slide.
[0012] Preferably, the receiving mechanism includes a pad, a receiving frame, an electric telescopic rod, and a magnetic plate; the pad is fixed to the top of the base and abuts against the side of the lower mold away from the storage rack, its top is flush with the lower surface of the middle position of the lower mold, the end of the pad away from the lower mold is fixedly connected to the inner side of the receiving frame, and the upper surface of the pad is flush with the top of the receiving frame; the cylinder of the electric telescopic rod is fixedly installed on the outer side of the receiving frame near the top via a mounting base, and the telescopic end of the electric telescopic rod is fixedly connected to the magnetic plate; a push rod is fixed to the top of the outer side of the receiving frame via a fixing plate, and a matching hole for the matching push rod is opened through the magnetic plate. When the upper die stamps the anti-collision beam, the telescopic rod of the electric telescopic rod extends, and the magnetic plate is located on the side of the lower die. After stamping, both ends of the anti-collision beam are raised, and the recessed groove can no longer block the anti-collision beam. The anti-collision beam is attracted by the magnetic plate, and the telescopic rod of the electric telescopic rod retracts. When the anti-collision beam moves to the top of the receiving frame, the abutment rod passes through the matching hole and abuts the anti-collision beam. The magnetic plate continues to reset under the drive of the electric telescopic rod. At this time, the anti-collision beam loses its attraction and falls into the receiving frame. The mounting plate has two parts, which are fixed to the bottom of the storage rack and the bottom of the pad respectively. They are locked in the slot at the top of the base.
[0013] Preferably, it further includes: an inner recessed groove, symmetrically opened on the front and back of the inner wall of the receiving frame, with a lifting plate hinged to the top of the groove; a spring cavity is opened on the inner side of the inner recessed groove near the middle, with a lifting spring inside the spring cavity, one end of the lifting spring abutting against the lifting plate; after the anti-collision beam falls into the receiving frame, it will be supported by two symmetrical lifting plates to prevent the anti-collision beam from falling and damaging the main body or the anti-collision beam below; and a material removal port, which is opened through the bottom of the outer side of the receiving frame; it is used to remove the formed anti-collision beam.
[0014] Preferably, it also includes extension rods, which are provided in two symmetrical positions fixed to the outer ends of the magnetic plate near the top. The outer ends of the two extension rods are fixed with pressing inclined plates, and the bottom end of the pressing inclined plates is on the same horizontal plane as the top of the receiving frame. When the extension rod of the electric telescopic rod extends and drives the magnetic plate to slide forward, the pressing inclined plates move above the receiving frame. The pressing inclined plates will press down on the anti-collision beam that is lifted by the lifting plate at the top of the receiving frame and protrudes from the receiving frame, so that the anti-collision beam passes over the lifting plate and completely enters the receiving frame. This will not affect the magnetic plate's reset or the entry of the next anti-collision beam into the receiving frame. It should be noted that when the anti-collision beam falls into the receiving frame and is lifted by the topmost lifting plate, the upper surface of the middle part of the anti-collision beam is below the receiving frame and will not affect the sliding of the magnetic plate.
[0015] Preferably, the reset mechanism includes pulleys, a belt, a linkage shaft, a toothed ring, a recessed groove, a toothed plate, a clamping plate, a clamping groove, and a through hole. Four pulleys are provided, each rotatably mounted inside the storage rack near the lower die. Two pulleys form a group and are connected by belt drive. The top of the belt is located above the storage rack. The belt is made of rubber, providing high friction. The two pulleys near the lower die are coaxially fixedly connected by the linkage shaft, and the toothed ring is coaxially fixedly mounted on the outer surface of the linkage shaft. The recessed groove is located at the top of the pad near the lower die, and the through hole is located through the lower die. The recessed groove communicates with the through hole. The toothed plate slides through the recessed groove and the through hole. The end of the toothed plate away from the pad extends into the storage rack, and the bottom teeth mesh with the top of the toothed ring. The plate is fixedly installed on the upper surface of the toothed plate at one end located in the recessed groove. The top of the clamping plate is located above the pad plate, and the clamping groove is opened at the bottom of the inner side of the magnetic plate. When the magnetic plate slides towards the lower mold, the clamping plate will be clamped into the clamping groove. Then, the magnetic plate pushes the toothed plate to slide through the clamping plate. When the toothed plate slides, it will drive the belt to rotate through the toothed ring, the linkage shaft, and the pulley. When the belt rotates, due to the large friction, it will push the anti-collision beam on the storage rack away from the lower mold, which can prevent the anti-collision beam on the storage rack from being crushed when the upper mold is pressed down. When the magnetic plate is reset, the push plate is pushed by the push spring to slide towards the lower mold to supply material to the lower mold. At the same time, the push plate pushes the anti-collision beam to slide, and the anti-collision beam will drive the pulley and the linkage shaft to rotate through the friction with the belt. At this time, the toothed plate begins to reset by meshing with the toothed ring.
[0016] The beneficial effects and advantages of this invention are as follows: 1. This invention achieves automated loading and unloading of anti-collision beams through a fully automatic feeding mechanism, receiving mechanism, and resetting mechanism, completely replacing the traditional process that requires manual insertion of arms into the closed area of the upper and lower molds, fundamentally eliminating serious safety accidents such as hand crushing and injury caused by accidental equipment startup or operational errors.
[0017] 2. The automated loading, unloading, and handling process of this invention eliminates the limitations of manual operation skills and physical exertion, enabling continuous and stable stamping operations. Through the automated connection of material supply, positioning, stamping, and material collection, the auxiliary time of single-piece processing cycle is effectively shortened, and the production cycle and overall capacity are greatly improved.
[0018] 3. By setting a drive screw and a drive motor with symmetrical threads, the support mechanism of this invention can move simultaneously and accurately towards each other, providing symmetrical support and positioning for both ends of the anti-collision beam. This dual-side synchronous and adjustable clamping method ensures the positional accuracy and stability of the anti-collision beam during the stamping and bending process, thereby improving the forming quality.
[0019] 4. The reset mechanism of this invention realizes the linkage between the feeding and receiving processes. When the magnetic plate moves forward, it will drive the toothed plate to rotate the belt, pulling the anti-collision beam to be processed on the storage rack away from the lower die. This action effectively prevents the unprocessed anti-collision beam on the storage rack from being crushed when the upper die presses down during die closing and stamping, thus protecting the raw materials.
[0020] 5. The material receiving mechanism of this invention is designed with magnetic plates to adsorb and pick up materials, and works with the lifting plate and lifting spring on the inner side of the receiving frame to flexibly receive materials, preventing finished products from falling directly and causing them to hit or collide and deform. At the same time, the extension rod design with pressing inclined plate can ensure that finished products that have fallen into the top of the receiving frame are completely pressed into place, without affecting the reset of the magnetic plate and the entry of the next anti-collision beam, thus realizing the orderly and safe stacking of finished products.
[0021] 6. This invention integrates multiple action mechanisms such as material storage, feeding, positioning, stamping, unloading, receiving, and resetting to prevent interference onto a single base. It utilizes mechanical mechanisms such as gear transmission, linkage shaft, and slide groove to achieve physical linkage of some actions. The structure is compact, reducing dependence on complex external control systems and ensuring stable and continuous operation. Attached Figure Description

A lower mold 14 is provided on the base 1. It also includes a support mechanism 2, which is slidably disposed on the top of the base 1. There are two such mechanisms symmetrical about the lower mold 14, which are used to support and position the two ends of the anti-collision beam. A feeding mechanism 3 is disposed on one side of the base 1, which is used to store the anti-collision beam to be processed and feed it to the lower mold 14. A receiving mechanism 4 is disposed on the side of the base 1 away from the feeding mechanism 3, which is used to unload and store the processed anti-collision beam. A reset mechanism 5 is linked between the receiving mechanism 4 and the feeding mechanism 3. The reset mechanism 5 is used to push the anti-collision beam on the feeding mechanism 3 so that the hydraulic mechanism 13 can operate smoothly.
[0026] Specifically, it also includes a base plate 15, which is fixedly installed on the top of the base 1, a lower mold 14, which is fixedly installed in the middle of the top of the base plate 15, and a support mechanism 2 that slides on the top of the base plate 15; a limiting slider 21, which is fixedly installed at the bottom of the support mechanism 2, the side of the limiting slider 21 is convex, and the top of the base plate 15 is provided with a limiting groove 151 that matches the limiting slider 21. The limiting slider 21 and the limiting groove 151 cooperate to limit and guide the support mechanism 2.
[0027] Specifically, it also includes screw grooves 22, which are opened on the top of the base plate 15. There are two of them, symmetrical about the lower mold 14. A drive screw 23 is rotatably installed in each of the two screw grooves 22. The threads of the two drive screws 23 are facing opposite directions. The two drive screws 23 are coaxially fixedly connected by a connecting shaft 24. A drive motor 25 is fixedly installed on the top of the base 1. The output shaft of the drive motor 25 is driven and connected to the outer end of one of the drive screws 23 through a reducer. There are two drive sliders 26, which are threadedly installed on the outer surface of the two drive screws 23 respectively. The tops of the two drive sliders 26 are fixedly connected to the bottoms of the two support mechanisms 2 respectively. When the drive motor 25 rotates forward and reverse, it can drive the two support mechanisms 2 to move towards or away from each other at the same time. When the two support mechanisms 2 move towards each other, they can simultaneously support and position both ends of the anti-collision beam. When the two support mechanisms 2 move away from each other, they can simultaneously release the anti-collision beam.
[0028] Specifically, the hydraulic mechanism 13 includes a hydraulic rod 131, a top plate 132, and an upper mold 133. The cylinder of the hydraulic rod 131 is fixedly installed on the top of the top seat 12, and the telescopic rod of the hydraulic rod 131 passes through the top seat 12 and is fixedly connected to the top plate 132. The upper mold 133 is fixedly installed on the bottom of the top plate 132 and is located directly above the lower mold 14. After the two support mechanisms 2 support the anti-collision beam, the telescopic rod of the hydraulic rod 131 extends out and presses the anti-collision beam through the upper mold 133. The pressure can be increased by pressing down the top plate 132 together.
[0029] Specifically, the feeding mechanism 3 includes a storage rack 31, a push plate 32, and a stabilizing frame 33. The storage rack 31 is L-shaped, with one end fixed to the top of the base 1 and abutting against one side of the lower mold 14. The upper surface of the storage rack 31 is flush with the top of the lower mold 14. The top of the stabilizing frame 33 is fixed to the bottom of the storage rack 31 at the end away from the lower mold 14, and the bottom of the stabilizing frame 33 is placed on the ground. The stabilizing frame 33 supports the outer end of the storage rack 31, providing auxiliary load-bearing. The push plate 32 slides. At the top of the storage rack 31, a guide rod 321 is fixedly installed on one side of the push plate 32. The guide rod 321 slides through the vertical section of the storage rack 31. A push spring 322 is provided between the push plate 32 and the vertical section of the storage rack 31. When loading, the guide rod 321 is pulled first to make the push plate 32 close to the vertical section of the storage rack 31. The anti-collision beam to be processed is placed on the storage rack 31. Under the action of the push spring 322, the push plate 32 pushes the anti-collision beam and pushes it onto the lower mold 14.
[0030] Specifically, the two ends of the lower mold 14 are protruding, and the top of the protrusion is flush with the upper surface of the storage rack 31. Both protruding tops are provided with recessed grooves 141. The width of the recessed grooves 141 is equal to the width of the anti-collision beam. When the push plate 32 pushes the anti-collision beam to slide to the top of the lower mold 14, the anti-collision beam will fall into the recessed grooves 141 under the action of gravity. The next anti-collision beam is blocked by the fallen anti-collision beam and cannot continue to slide.
[0031] Specifically, the receiving mechanism 4 includes a pad 41, a receiving frame 42, an electric telescopic rod 43, and a magnetic plate 44. The pad 41 is fixed to the top of the base 1 and abuts against the side of the lower mold 14 away from the storage rack 31. Its top is flush with the lower surface of the middle position of the lower mold 14. The end of the pad 41 away from the lower mold 14 is fixedly connected to the inner side of the receiving frame 42. The upper surface of the pad 41 is flush with the top of the receiving frame 42. The cylinder of the electric telescopic rod 43 is fixedly installed on the outer side of the receiving frame 42 near the top through the mounting base 431. The telescopic end of the electric telescopic rod 43 is fixedly connected to the magnetic plate 44. A push rod 423 is fixed to the top of the outer side of the receiving frame 42 through the fixing plate 421. A matching push rod 423 is provided through the magnetic plate 44. Matching hole 441 of 23; When the upper die 133 stamps the anti-collision beam, the telescopic rod of the electric telescopic rod 43 extends, and the magnetic plate 44 is located on the side of the lower die 14. After the stamping is completed, the two ends of the anti-collision beam are raised, and the recessed groove 141 can no longer block the anti-collision beam. The anti-collision beam is attracted by the magnetic plate 44, and the telescopic rod of the electric telescopic rod 43 retracts. When the anti-collision beam moves to the top of the receiving frame 42, the abutting rod 423 passes through the matching hole 441 and abuts the anti-collision beam. The magnetic plate 44 continues to reset under the drive of the electric telescopic rod 43. At this time, the anti-collision beam loses its attraction and falls into the receiving frame 42. The mounting plate 6 has two plates and is fixed to the bottom of the storage rack 31 and the bottom of the pad 41 respectively. It is locked in the slot at the top of the base 1.
[0032] Specifically, it also includes an inner recess 424, which is symmetrically opened on the front and back of the inner wall of the receiving frame 42. The top of the inner recess is hinged to a support plate 425. A spring cavity 426 is opened on the inner side of the inner recess 424 near the middle. A support spring 427 is installed inside the spring cavity 426. One end of the support spring 427 abuts against the support plate 425. After the anti-collision beam falls into the receiving frame 42, it will be supported by two symmetrical support plates 425 to prevent the anti-collision beam from falling and damaging the main body or the anti-collision beam below. The material removal port 428 is opened through the bottom of the outer side of the receiving frame 42. It is used to remove the formed anti-collision beam.
[0033] Specifically, it also includes extension rods 45, which are provided in two symmetrical positions fixed to the outer ends of the magnetic plate 44 near the top. The outer ends of the two extension rods 45 are fixed with pressing inclined plates 451. The bottom end of the pressing inclined plate 451 is on the same horizontal plane as the top of the receiving frame 42. When the extension rod of the electric telescopic rod 43 extends and drives the magnetic plate 44 to slide forward, the pressing inclined plate 451 moves above the receiving frame 42. The pressing inclined plate 451 will press down on the anti-collision beam that is lifted by the lifting plate 425 at the top of the receiving frame 42 and protrudes from the receiving frame 42. This will cause the anti-collision beam to pass over the lifting plate 425 and completely enter the receiving frame 42, so that it will not affect the reset of the magnetic plate 44 and will not affect the entry of the next anti-collision beam into the receiving frame 42. It should be noted that when the anti-collision beam falls into the receiving frame 42 and is lifted by the topmost lifting plate 425, the upper surface of the middle part of the anti-collision beam is below the receiving frame 42 and will not affect the sliding of the magnetic plate 44.
[0034] Specifically, the reset mechanism 5 includes pulleys 51, a belt 52, a linkage shaft 53, a toothed ring 54, a recessed groove 55, a toothed plate 56, a clamping plate 57, a clamping groove 58, and a through hole 59. Four pulleys 51 are provided and rotatably installed inside the storage rack 31 near one end of the lower mold 14. Each pair of pulleys 51 forms a group and is connected by a belt 52. The top of the belt 52 is located above the storage rack 31. The belt 52 is made of rubber and has high friction. The two pulleys near the lower mold 14... A pulley 51 is coaxially fixedly connected to a linkage shaft 53, and a toothed ring 54 is coaxially fixedly installed on the outer surface of the linkage shaft 53. A recessed groove 55 is formed at the top of the pad 41 near the lower mold 14, and a through hole 59 is formed through the lower mold 14. The recessed groove 55 communicates with the through hole 59. A toothed plate 56 slides through the recessed groove 55 and the through hole 59. The end of the toothed plate 56 away from the pad 41 extends into the storage rack 31, and the bottom teeth mesh with the top of the toothed ring 54. The clamping plate 57 is fixedly installed on one end of the upper surface of the toothed plate 56, located within the recessed groove 55. The top of the clamping plate 57 is located above the pad 41, and the groove 58 is opened at the bottom of the inner side of the magnetic plate 44. When the magnetic plate 44 slides towards the lower mold 14, the clamping plate 57 will engage in the groove 58. Then, the magnetic plate 44 pushes the toothed plate 56 to slide through the clamping plate 57. When the toothed plate slides, it drives the belt 52 to rotate through the toothed ring 54, the linkage shaft 53, and the pulley 51. When the belt 52 rotates, due to friction... The force is relatively large, which will push the anti-collision beam on the storage rack 31 away from the lower mold 14, which can prevent the upper mold 133 from crushing the anti-collision beam on the storage rack 31 when it presses down; when the magnetic plate 44 is reset, the push plate 32 is pushed by the push spring 322 to slide towards the lower mold 14 to supply material to the lower mold 14. While the push plate 32 pushes the anti-collision beam to slide, the anti-collision beam will drive the pulley 51 and the linkage shaft 53 to rotate through the friction with the belt 52. At this time, the toothed plate 56 begins to reset by meshing with the toothed ring 54.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
