Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision beam bending molds, specifically an automotive anti-collision beam bending mold. Background Technology

[0002] Automotive crash beam bending dies are specialized tools used to bend crash beam materials. Through the specific structure of the die, the crash beam is pressed into the required curved shape. The die is usually made of high-strength materials (such as H13 and P20 die steel) and combined with precision machining technology (such as five-axis CNC machining) to ensure forming accuracy. It is mainly used to press crash beam materials (such as cold-rolled steel plates) into U-shaped grooves or double groove structures, and to achieve precise forming of complex shapes by controlling the material flow.

[0003] For example, the bending forming mold for a crash beam disclosed in the authorization announcement number CN219325522U includes an upper mold and a lower mold. The height of the forming surface of the upper mold gradually increases from the middle to both ends. It also includes a clamping assembly, which includes two clamping units. The two clamping units are respectively disposed at both ends of the crash beam. The clamping unit includes a rotating frame, which is rotatably connected to the lower mold, and the rotating frame clamps one end of the crash beam.

[0004] Although it achieves the goal of setting a clamping unit at each end of the anti-collision beam, and fixing the end of the workpiece by the rotating frame in the clamping unit, during the bending and forming process of the anti-collision beam, the rotating frame rotates along with the forming of the anti-collision beam, so that the end and middle of the anti-collision beam can be bent and formed together. The anti-collision beam is set at each end of the anti-collision beam to clamp the two ends of the anti-collision beam. When the anti-collision beam is formed, the rotating frame rotates along with the forming of the middle. There is no need to open the forming surface on the lower mold. The anti-collision beam can be bent and formed as a whole only by opening the forming surface on the upper mold, which reduces the cost of mold opening.

[0005] However, this does not solve the problem that existing anti-collision beam bending molds are generally not convenient to move to easily pick up and put down the anti-collision beams during use, which affects the convenience of picking up and putting down the anti-collision beams, making it inconvenient to move them to the outside for picking up and putting down the anti-collision beams, and making it inconvenient to eject and replace the anti-collision beams, thus affecting the working efficiency of the anti-collision beam bending molds. Utility Model Content

[0006] The purpose of this utility model is to provide an automotive anti-collision beam bending mold to solve the problems mentioned in the background art, such as the inconvenience of moving the anti-collision beam bending mold to a convenient location for picking up and placing the anti-collision beam, which affects the convenience of picking up and placing the anti-collision beam, makes it inconvenient to move it to the outside for picking up and placing the anti-collision beam, and makes it inconvenient to eject and replace the anti-collision beam, thus affecting the working efficiency of the anti-collision beam bending mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bending mold for an automotive anti-collision beam, comprising a base and a support base. A support base is symmetrically mounted on the top of the base, a support frame is mounted on the top of the support base, a hydraulic cylinder is mounted on the top of the support frame, an upper mold is mounted on the output end of the hydraulic cylinder, a lower mold is disposed outside the upper mold, two sets of L-shaped blocks are symmetrically mounted on the inner wall of the support frame, and limit posts are fitted between the two sets of L-shaped blocks. The upper mold is slidably connected to the limit posts, and springs are fitted on the surface of each limit post. The top ends of the springs are connected to the upper mold, and the bottom ends of the springs... All are connected to L-shaped blocks. Servo motors are symmetrically installed on the side walls of the support base. Each servo motor has a first threaded rod installed at its output end. Each first threaded rod extends into the interior of the support base and is movably connected to it. Each first threaded rod has a first threaded block fitted on its surface. The first threaded rod and the first threaded block are threadedly connected. Each first threaded block is connected to the lower mold. A slider is symmetrically installed at the bottom end of the lower mold. Each support base has a guide rail installed at its top end. The slider is slidably connected to the guide rail. Each support base has a first cylinder installed on the side of its top end near the guide rail. Each first cylinder has a telescopic rod installed at its output end.

[0008] Preferably, a support frame is installed on the bottom side wall of the lower mold, a second cylinder is installed inside the support frame, a support block is installed at the output end of the second cylinder, and the support block extends through the support frame to its outside.

[0009] Preferably, a rack is installed on the side wall of the external support block of the support frame, a groove is provided on the surface of the support frame, the support block is slidably connected to the groove, and two sets of second support columns are movably installed on the top of the support frame.

[0010] Preferably, multiple sets of first support columns are installed on the outside of the second support column at the top of the support frame, and a limit frame is installed on the side of the support frame away from the first support columns, and the rack is slidably connected to the limit frame.

[0011] Preferably, the surface of the second support column is fitted with a small gear, the rack meshes with the small gear, the surface of the second support column above the small gear is fitted with a large gear, and the surface of the first support column is fitted with a threaded sleeve.

[0012] Preferably, the surface of each threaded sleeve is fitted with a first gear, which meshes with a large gear, and a second threaded rod is movably installed inside each threaded sleeve.

[0013] Preferably, all the threaded sleeves are threadedly connected to the second threaded rod, and the top end of the second threaded rod is equipped with a pin.

[0014] Preferably, the bottom end of the lower mold is equipped with multiple sets of limiting blocks, the second threaded rods are all connected to the limiting blocks, and the ejector pins all extend through the lower mold to its outside.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the anti-collision beam bending mold not only realizes the convenient movement of the anti-collision beam bending mold to pick up and put down the anti-collision beam, but also improves the convenience of picking up and putting down the anti-collision beam, facilitates the removal and placement of the anti-collision beam to the outside, facilitates the convenient ejection and replacement of the anti-collision beam, reduces the labor intensity of manual labor, and improves the working efficiency of the anti-collision beam bending mold.

[0016] The servo motor drives the first threaded rod to rotate, which in turn moves two sets of first threaded blocks. These first threaded blocks then move the lower mold and support frame, bringing the lower mold to the loading area. The anti-collision beam is placed on the surface of the lower mold. The two servo motors are then activated in the reverse direction, causing the servo motors to drive the first threaded rod to rotate. This, in turn, moves the two sets of first threaded blocks in the opposite direction. The first threaded blocks then move the lower mold, support frame, and anti-collision beam to the stamping area. The two sets of first cylinders are then activated, causing the telescopic rod to move upwards. The telescopic rod clamps the lower mold, and the hydraulic cylinder drives the upper mold to move downward. The upper mold slides downward along the surface of the limiting post. Under the elastic support of the spring, the spring buffers the upper mold, causing the upper mold to press the anti-collision beam into the interior of the lower mold. This avoids damage to the anti-collision beam due to excessive impact force, and enables convenient movement of the anti-collision beam bending mold to pick up and put down the anti-collision beam. This improves the convenience of picking up and putting down the anti-collision beam, facilitates the removal and placement of the anti-collision beam from the outside, and enhances the safety of picking up and putting down the anti-collision beam by moving the anti-collision beam bending mold.

[0017] A servo motor drives the first threaded rod to rotate, causing it to move the first threaded block, the lower mold, and the support frame to the loading area. A second cylinder drives the support block to move on the surface of the slide groove. The support block drives the rack to move, which in turn drives two sets of pinions to rotate. The pinions drive the large gear to rotate, which in turn drives multiple sets of first gears to rotate. The first gears drive multiple sets of threaded sleeves to rotate. With the support of the limit block, multiple sets of second threaded rods rise to a certain position inside the multiple sets of first gears. The multiple sets of second threaded rods drive multiple sets of ejector pins to rise, causing the ejector pins to push the anti-collision beam out to the surface of the lower mold for replacement. This enables convenient ejection and replacement of the anti-collision beam in the anti-collision beam bending mold, reducing manual labor intensity and improving the working efficiency of the anti-collision beam bending mold.

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please see Figure 1-8This utility model provides an embodiment of a car anti-collision beam bending mold, comprising a base 1 and a support base 2. The support base 2 is symmetrically mounted on the top of the base 1, and a support frame 3 is mounted on the top of the support base 2. A hydraulic cylinder 4 is mounted on the top of the support frame 3. An upper mold 5 is mounted on the output end of the hydraulic cylinder 4. A lower mold 6 is disposed outside the upper mold 5. Two sets of L-shaped blocks 8 are symmetrically mounted on the inner wall of the support frame 3, and limit posts 9 are fitted between the two sets of L-shaped blocks 8. The upper mold 5 is slidably connected to the limit posts 9. Springs 10 are fitted on the surface of each limit post 9, with the top of each spring 10 connected to the upper mold 5 and the bottom of each spring 10 connected to the L-shaped blocks 8. Servo motors 11 are symmetrically installed on the side walls of the support base 2. Each output end of the servo motor 11 is equipped with a first threaded rod 12. The first threaded rod 12 extends into the interior of the support base 2 and is movably connected thereto. Each surface of the first threaded rod 12 is fitted with a first threaded block 13. The first threaded rod 12 and the first threaded block 13 are threadedly connected. The first threaded block 13 is connected to the lower mold 6. A slider 15 is symmetrically installed at the bottom end of the lower mold 6. A guide rail 14 is installed at the top end of the support base 2. The slider 15 is slidably connected to the guide rail 14. A first cylinder 16 is installed on the side of the top end of the support base 2 near the guide rail 14. A telescopic rod 30 is installed at the output end of each first cylinder 16.

[0029] When using the automotive anti-collision beam bending die, two sets of servo motors 11 are activated. Supported by the support base 2, the servo motors 11 drive the first threaded rod 12 to rotate. With the threaded connection between the first threaded rod 12 and the first threaded block 13, the first threaded rod 12 drives the two sets of first threaded blocks 13 to move. Supported by the guide rail 14 and the slider 15, the first threaded blocks 13 drive the lower die 6 and the support frame 7 to move, allowing the lower die 6 to move to the loading area and place the anti-collision beam on the surface of the lower die 6. Then, the two sets of servo motors 11 are activated in the opposite direction, causing the servo motors 11 to drive the first threaded rod 12 to rotate. The first threaded rod 12 drives the two sets of first threaded blocks 13 to move in the opposite direction, allowing the first threaded blocks 13 to move the lower die 6, the support frame 7, and the anti-collision beam to the stamping area. Finally, the two sets of first cylinders 16 are activated, and the first cylinders 16 drive the telescopic rod 30. The upper mold 5 is moved upwards, causing the telescopic rod 30 to press against the lower mold 6 to prevent excessive pressure during stamping from damaging the guide rail 14 and the slider 15. The hydraulic cylinder 4 is opened, and under the support of the support frame 3, the hydraulic cylinder 4 drives the upper mold 5 to move downwards. Under the support of the L-shaped block 8, the upper mold 5 slides downwards along the surface of the limit post 9. Under the elastic support of the spring 10, the spring 10 buffers the upper mold 5, causing the upper mold 5 to press the anti-collision beam into the interior of the lower mold 6. This avoids damage to the anti-collision beam due to excessive impact force, and realizes the convenient movement position of the anti-collision beam bending mold to pick up and put down the anti-collision beam. This improves the convenience of picking up and putting down the anti-collision beam, facilitates the removal and placement of the anti-collision beam from the outside, and improves the safety of picking up and putting down the anti-collision beam by moving the anti-collision beam bending mold.

[0030] A support frame 7 is installed on the bottom side wall of the lower mold 6. A second cylinder 17 is installed inside the support frame 7. A support block 18 is installed at the output end of the second cylinder 17. The support block 18 extends through the support frame 7 to its outside.

[0031] A rack 19 is installed on the side wall of the external support block 18 of the support frame 7, and a groove 31 is provided on the surface of the support frame 7. The support block 18 is slidably connected to the groove 31, and two sets of second support columns 26 are movably installed on the top of the support frame 7.

[0032] Multiple sets of first support columns 20 are installed on the outside of the second support column 26 at the top of the support frame 7. A limit frame 29 is installed on the side of the support frame 7 away from the first support column 20. The rack 19 is slidably connected to the limit frame 29.

[0033] The surface of the second support column 26 is fitted with small gears 27, the rack 19 meshes with the small gears 27, the surface of the second support column 26 above the small gears 27 is fitted with large gears 28, and the surface of the first support column 20 is fitted with threaded sleeves 21.

[0034] The surface of each threaded sleeve 21 is fitted with a first gear 22, which meshes with a large gear 28. The inside of each threaded sleeve 21 is movably installed with a second threaded rod 23, and each threaded sleeve 21 is threadedly connected to the second threaded rod 23. The top of each second threaded rod 23 is fitted with a pin 25.

[0035] Multiple sets of limiting blocks 24 are installed at the bottom of the lower mold 6. The second threaded rods 23 are all connected to the limiting blocks 24, and the ejector pins 25 all penetrate the lower mold 6 and extend to its outside.

[0036] When it is necessary to eject the stamped anti-collision beam, two sets of servo motors 11 are activated. The servo motors 11 drive the first threaded rod 12 to rotate. Under the threaded connection between the first threaded rod 12 and the first threaded block 13, and with the sliding support of the guide rail 14 and the slider 15, the first threaded rod 12 moves the first threaded block 13, the lower mold 6, and the support frame 7 to the loading area. The second cylinder 17 is activated. With the support of the support frame 7, the second cylinder 17 drives the support block 18 to move on the surface of the slide groove 31. The support block 18 drives the rack 19 to move. With the meshing of the rack 19 and the pinion 27, the rack 19 drives the two sets of pinions 27 to rotate. With the support of the second support column 26, the pinions 27 drive the large gear 28 to rotate. With the meshing of wheel 28 and first gear 22, the large gear 28 drives multiple sets of first gears 22 to rotate, and the first gears 22 drive multiple sets of threaded sleeves 21 to rotate. With the threaded connection between the second threaded rod 23 and the threaded sleeve 21, and supported by the limiting block 24, the limiting block 24 slides inside the lower mold 6 to prevent the second threaded rod 23 and the threaded sleeve 21 from rotating synchronously. This causes multiple sets of second threaded rods 23 to rise to a certain position inside the multiple sets of first gears 22. The multiple sets of second threaded rods 23 drive multiple sets of ejector pins 25 to rise, causing the multiple sets of ejector pins 25 to push the anti-collision beam out to the surface of the lower mold 6 for replacement. This realizes the convenient ejection and replacement of the anti-collision beam in the anti-collision beam bending mold, reduces the labor intensity of manual labor, and improves the working efficiency of the anti-collision beam bending mold.

[0037] Working principle: Servo motor 11 drives the first threaded rod 12 to rotate, which in turn drives two sets of first threaded blocks 13 to move. The first threaded blocks 13 then move the lower mold 6 and support frame 7, moving the lower mold 6 to the loading area and placing the anti-collision beam on the surface of the lower mold 6. The two sets of servo motors 11 are then turned in the opposite direction, causing the servo motor 11 to drive the first threaded rod 12 to rotate. The first threaded rod 12 then drives the two sets of first threaded blocks 13 to move in the opposite direction, moving the lower mold 6, support frame 7, and anti-collision beam to the stamping area. Hydraulic cylinder 4 drives the upper mold 5 to move downwards. Supported by L-shaped block 8, the upper mold 5 slides downwards along the surface of the limiting post 9. Supported by the elasticity of spring 10, the spring 10 buffers the upper mold 5, causing the upper mold 5 to press the anti-collision beam into the interior of the lower mold 6. The servo motor 11 drives the first threaded rod 12 to rotate, causing the first threaded rod 12 to move the first threaded block 13, the lower mold 6, and the support frame 7 to the loading area. The second cylinder 17 drives the support block 18 to move on the surface of the slide groove 31. The support block 18 drives the rack 19 to move, and the rack 19 drives two sets of pinions 27 to rotate. Under the support of the second support column 26, the pinions 27 drive the large gear 28 to rotate, and the large gear 28 drives multiple sets of first gears 22 to rotate. The first gears 22 drive multiple sets of threaded sleeves 21 to rotate, causing multiple sets of second threaded rods 23 to rise to a certain position inside the multiple sets of first gears 22. The multiple sets of second threaded rods 23 drive multiple sets of ejector pins 25 to rise, causing the multiple sets of ejector pins 25 to push the anti-collision beam out to the surface of the lower mold 6 for replacement, thus completing the use of the anti-collision beam bending mold.
