Detailed Implementation

[0049] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0050] This invention provides a bending machine mold that solves the problem of springback caused by different workpiece materials in the prior art. From ordinary plates to high-strength plates, different plates have different yield strengths. The higher the yield strength of the plate, the more likely springback will occur. The springback of parts with different shapes varies greatly. Parts with complex shapes usually have an additional forming step to prevent springback due to incomplete forming. Furthermore, some special-shaped parts are more prone to springback.

[0051] To solve the above-mentioned technical problems, the overall technical concept of this invention is as follows: the male mold 1 presses down and drives the female mold 2 to move downward through the lifting mechanism 3. During the lifting process, the lifting mechanism 3 drives the rotating mechanism 4 to move due to the action of the first spring 32. The rotating mechanism 4 drives the pushing mechanism 5 to work. Then, the collecting box 6 cooperates with the pushing mechanism 5 to solve the problem of springback after extrusion processing of tough materials.

[0052] This invention provides a bending machine mold, including a support 22, a hydraulic press fixedly connected above the support 22, a male mold 1 fixedly connected below the hydraulic rod of the hydraulic press, and further comprising:

[0053] Female mold 2, which is located below male mold 1;

[0054] Lifting mechanism 3, located below female mold 2, works in conjunction with male mold 1 to extrude the workpiece;

[0055] Rotating mechanism 4, which is located to the left of lifting mechanism 3;

[0056] Pushing mechanism 5 is located on the left side of female mold 2. Pushing mechanism 5 and rotating mechanism 4 cooperate to push the processed workpiece.

[0057] Collection box 6 is slidably connected to the right side of lifting mechanism 3, and is used to shape and collect the extruded workpiece.

[0058] When the workpiece is being processed on the surface of the female mold 2 below the male mold 1, the hydraulic press fixedly connected above the bracket 22 is started. The hydraulic rod in the hydraulic press drives the male mold 1, which is fixedly connected to it, to move downward. The male mold 1 presses downward, and the female mold 2 descends with the male mold 1 through the lifting mechanism 3 fixedly connected at the bottom. During the downward pressing of the female mold 2, the male mold 1 moves upward after processing. The female mold 2 moves upward with the male mold 1 due to the lifting mechanism 3 below. During the upward movement of the female mold 2, the rotating mechanism 4 fixedly connected to the left side of the female mold 2 rotates, thereby driving the pushing mechanism 5 to work, so that the processed workpiece enters the collection box 6 slidably connected to the right side of the female mold 2.

[0059] The male mold 1 presses down, causing the female mold 2 to move downward through the lifting mechanism 3. The rotating mechanism 4 drives the pushing mechanism 5 to work, and the collection box 6, in conjunction with the pushing mechanism 5, solves the problem of springback that occurs after the extrusion processing of tough materials.

[0060] In one specific embodiment of the present invention, the lifting mechanism 3 includes:

[0061] Lifting platform 31, the lifting platform 31 is located below the female mold 2 and the female mold 2 is slidably connected to the upper surface of the lifting platform 31;

[0062] At least two No. 1 springs 32 are provided at the bottom of the lifting platform 31;

[0063] Limiting shell 33; a lifting platform 31 is slidably connected inside the limiting shell 33, which plays a limiting role for the lifting platform 31.

[0064] A lifting platform 31 is slidably connected below the female mold 2. A first spring 32 is fixedly connected to the bottom of the lifting platform 31, and the other end of the first spring 32 is fixedly connected to the bottom of the limiting shell 33. When the male mold 1 comes above the female mold 2 and presses the workpiece downward, the female mold 2 is forced to press the first spring 32, which causes the first spring 32 to move downward, and then the female mold 2 moves downward to complete the pressing work on the workpiece. When the male mold 1 moves upward after completing the processing, the female mold 2 will rise due to the rebound of the first spring 32 below it, placing the lifting platform 31 inside the limiting shell 33 so that the lifting platform 31 can slide inside the limiting shell 33, which can limit the movement trajectory of the lifting platform 31. Furthermore, a support column can also be sleeved inside the first spring 32. The support column is multi-sectioned and the adjacent two sections are telescopic. The upper end of the support column is fixedly connected to the lifting platform 31, and the lower end is fixedly connected to the bottom of the limiting shell 33, which can further limit the lifting platform 31.

[0065] In one specific embodiment of the present invention, the rotating mechanism 4 includes:

[0066] Rack 41, the rack 41 is located on the outer surface of the left side wall of the lifting platform 31;

[0067] Fixed plate 42, the side wall of the lifting platform 31 is provided with fixed plate 42 and is located on one side of rack 41;

[0068] A ratchet mechanism 43 is engaged on the left side of the rack 41; the ratchet mechanism 43 includes an outer wheel 431, a limiting groove is formed inside the outer wheel 431, and a pawl 432 is rotatably connected inside the limiting groove; an inner wheel 433 is provided inside the outer wheel 431; the outer wheel 431 and the inner wheel 433 are coaxial;

[0069] Long shaft 44, the ratchet mechanism 43 is provided with a long shaft 44 in the middle and is rotatably connected to the fixed plate 42;

[0070] The fixing frame 45 is provided on the side of the long shaft 44 away from the fixing plate 42 and is rotatably connected to it;

[0071] The wheel 46 is provided on the surface of the fixed frame 45 and is fixedly connected to the long shaft 44.

[0072] When the male mold 1 drives the female mold 2 to press down via the lifting mechanism 3, the rack 41 fixedly connected to the left side of the lifting platform 31 moves downward accordingly. A ratchet mechanism 43 meshes with the surface of the rack 41. When the rack 41 moves downward, it drives the outer wheel 431, which is rotatably connected to the long shaft 44, to rotate. Figure 7As shown, the outer wheel 431 rotates clockwise at this time. Because a limiting groove is provided inside the outer wheel 431, and the right sidewall of the limiting groove contacts the pawl 432 hinged inside the limiting groove, when the rack 41 moves down, it drives the outer wheel 431 to rotate clockwise. At this time, the pawl 432 cannot drive the inner wheel 433 to rotate. Conversely, when the outer wheel 431 rotates counterclockwise, the limiting groove on the right side of the pawl 432 causes the pawl 432 to engage with the ratchet fixedly connected to the inner wheel 433. That is, the counterclockwise rotating outer wheel 431 can drive the inner wheel 433 fixedly connected to the surface of the long shaft 44 to rotate. Utilizing the principle that the ratchet mechanism 43 can only rotate in one direction and cannot reverse, when the lifting mechanism 3 rises, the ratchet mechanism 43 rotates counterclockwise, driving the internal fixed connection... The long shaft 44 rotates. To fix the long shaft 44, a fixed plate 42 is rotatably connected to one side of the long shaft 44 and fixedly connected to the outer left wall of the lifting platform 31. A fixed frame 45 is rotatably connected to the other side of the long shaft 44, and a wheel 46 is rotatably connected to the surface of the fixed frame 45. When the ratchet mechanism 43 rotates counterclockwise, it drives the long shaft 44 to rotate, which in turn drives the wheel 46 fixedly connected to the long shaft 44 to rotate. When the lifting mechanism 3 descends, the outer surface of the ratchet mechanism 43 meshes with the rack 41 and rotates, while the inside does not rotate. Therefore, it cannot drive the long shaft 44 to rotate. This means that the push mechanism 5 on one side of the lifting mechanism 3 only works when the lifting platform 31 rises and does not work when the lifting platform 31 descends, preventing the push mechanism 5 from interfering with the descending lifting platform 31.

[0073] In one specific embodiment of the present invention, the pushing mechanism 5 includes:

[0074] The second spring 51 is located between the female mold 2 and the side wall of the lifting platform 31, and there are at least two of them;

[0075] Groove 52: A groove 52 is provided on the surface of the lifting platform 31 between the two second springs 51.

[0076] The fixing block 53 is located on the surface of the wheel 46, and a U-shaped groove 531 is formed inside the fixing block 53.

[0077] Slider 54, the surface of the wheel 46 is provided with slider 54 and slider 54 is located in U-shaped groove 531;

[0078] Link 55, the fixing block 53 is fixedly connected to the surface of the fixing block 53;

[0079] Long rod 56, which is provided above the connecting rod 55 and is located inside the fixing frame 45;

[0080] Electric push rod 57, which is installed inside the long rod 56.

[0081] After the workpiece is extruded, the male mold 1 rises, and the workpiece on the surface of the female mold 2 adheres to the male mold 1. The first spring 32 inside the lifting platform 31 moves upward with the male mold 1 due to its own elasticity, ensuring that the workpiece always adheres to the male mold 1 and preventing the part from springing back. The upward movement of the female mold 2 drives the rack 41 fixedly connected to its side to move, thereby driving the ratchet mechanism 43 to rotate. At this time, the ratchet mechanism 43 rotates counterclockwise, driving the long shaft 44 to move. A slider 54 is fixedly connected to the surface of the wheel 46, and a fixing block 53 is fixedly connected above the fixing frame 45 and close to the side of the wheel 46. The slider 54 is located in the U-shaped groove 531 opened inside the fixing block 53. The wheel 46 rotates counterclockwise with the long shaft 44. The fixed block 53 slides in the U-shaped groove 531, and a connecting rod 55 is fixedly connected to the surface of the fixed block 53. When the fixed block 53 is moved by the slider 54 in the U-shaped groove 531, the connecting rod 55 moves accordingly. The connecting rod 55 drives the connected long rod 56 to move, and the long rod 56 is slidably connected in the fixed frame 45. The fixed frame 45 can support the long rod 56 to move linearly. The long rod 56 pushes the female mold 2 to the left side of the collection box 6. As the lifting platform 31 follows the male mold 1 and slowly rises, it is flush with the inner groove of the collection box 6. At this time, the long rod 56 and the bottom groove of the processed part on the surface of the female mold 2 are aligned. The long rod 56 can push the female mold 2 towards the collection box 6. The electric push rod 57 is parallel to the side wall of the workpiece. A pressure sensor is provided on the contact surface between the long rod 56 and the female mold 2. When the long rod 56 contacts the female mold 2, the electric push rod 57 starts. When the long rod 56 pushes the female mold 2 to the side of the collection box 6, the electric push rod 57 pushes the workpiece into the collection box 6. When the long rod 56 extends, the electric push rod 57 also extends. In order for the long rod 56 to continue working, after the workpiece enters the collection box 6, the lifting platform 31 continues to rise, and the rack 41 drives the ratchet mechanism 43 to continue to rotate, so that the slider 54 rotates counterclockwise from point A to point B on the surface of the wheel 46. The rod 56 retracts to its original position. Two No. 2 springs 51 are fixedly connected between the side wall of the collection box 6 and the female mold 2. After the pushing work is completed, the long rod 56 retracts, and the female mold 2 can retract according to the elastic force of the No. 2 springs 51. A groove 52 is provided between the two No. 2 springs 51 and on the side of the lifting platform 31 to provide space for the movement of the long rod 56. When the lifting platform 31 drives the female mold 2 to rise, the long rod 56 will move inside the groove 52 to prevent the long rod 56 from blocking the movement of the female mold 2. The long rod 56 can work in the groove 52. Due to the action of the ratchet mechanism 43 mentioned above, the pushing mechanism 5 will not work when the lifting platform 31 descends.

[0082] As a specific embodiment of the present invention, the collection box 6 is equipped with a track and the workpiece size is consistent with the specifications.

[0083] In one specific embodiment of the present invention, the collection box 6 is provided with blocking blocks 61 on both sides.

[0084] In one specific embodiment of the present invention, a friction strip 62 is provided below the blocking block 61.

[0085] In one specific embodiment of the present invention, the inner wall surface of the collection box 6 is provided with rubber 63.

[0086] The inner track of the collection box 6 is consistent with the size and specifications of the workpiece, allowing the workpiece to enter the track smoothly. Rubber 63 is provided on the track surface to prevent the workpiece from being bumped or scratched when entering the track. To prevent the tough material from springing back after the workpiece is processed, abutment blocks 61 are provided on both sides of the track inside the collection box 6. The workpiece can be stuck on the abutment block 61 after entering the collection box 6 from the female mold 2, so that it will not spring back. Sometimes the workpiece is freshly cut and the cut surface has burrs. Therefore, friction strips 62 are provided on the surface of the abutment block 61. When the workpieces enter the collection box 6 one after another from the female mold 2, the workpieces behind push the workpieces in front to move on the track. The cut surface of the workpiece will slide and rub against the surface of the friction strip 62, which can rub off the burrs on the cut surface of the workpiece.

[0087] In one specific embodiment of the present invention, a sensor 21 is provided on the side of the female mold 2 near the collection box 6.

[0088] In one specific embodiment of the present invention, the first spring 32 is a high-strength hard spring.

[0089] A sensor 21 is provided on the side of the female mold 2 near the collection box 6. When the long rod 56 pushes the female mold 2 to the left side of the collection box 6, the sensor 21 is linked to the electric push rod 57. At this time, the electric push rod 57 extends out from inside the long rod 56. Meanwhile, in order to enable the lifting platform 31 to withstand the downward squeezing force of the male mold 1, the spring in the lifting platform 31 is a high-strength hard spring.

[0090] Working principle:

[0091] When the workpiece is being processed on the surface of the female mold 2 below the male mold 1, the hydraulic press fixedly connected above the bracket 22 is started. The hydraulic rod in the hydraulic press drives the male mold 1, which is fixedly connected to it, to move downward. The male mold 1 presses downward, and the female mold 2 descends with the male mold 1 through the lifting mechanism 3 fixedly connected at the bottom. During the downward pressing of the female mold 2, the male mold 1 moves upward after processing. The female mold 2 moves upward with the male mold 1 due to the lifting mechanism 3 below. During the upward movement of the female mold 2, the rotating mechanism 4 fixedly connected to the left side of the female mold 2 rotates, thereby driving the pushing mechanism 5 to work, so that the processed workpiece enters the collection box 6 slidably connected to the right side of the female mold 2.

[0092] The male mold 1 presses down, causing the female mold 2 to move downward through the lifting mechanism 3. The rotating mechanism 4 drives the pushing mechanism 5 to work, and the collection box 6, in conjunction with the pushing mechanism 5, solves the problem of springback that occurs after the extrusion processing of tough materials.

[0093] A lifting platform 31 is slidably connected below the female mold 2. A first spring 32 is fixedly connected to the bottom of the lifting platform 31, and the other end of the first spring 32 is fixedly connected to the bottom of the limiting shell 33. When the male mold 1 comes above the female mold 2 and presses the workpiece downward, the female mold 2 is forced to press the first spring 32, which causes the first spring 32 to move downward, and then the female mold 2 moves downward to complete the pressing work on the workpiece. When the male mold 1 moves upward after completing the processing, the female mold 2 will rise due to the rebound of the first spring 32 below it, placing the lifting platform 31 inside the limiting shell 33 so that the lifting platform 31 can slide inside the limiting shell 33, which can limit the movement trajectory of the lifting platform 31. Furthermore, a support column can also be sleeved inside the first spring 32. The support column is multi-sectioned and the adjacent two sections are telescopic. The upper end of the support column is fixedly connected to the lifting platform 31, and the lower end is fixedly connected to the bottom of the limiting shell 33, which can further limit the lifting platform 31.

[0094] When the male mold 1 drives the female mold 2 to press down via the lifting mechanism 3, the rack 41 fixedly connected to the left side of the lifting platform 31 moves downward accordingly. A ratchet mechanism 43 meshes with the surface of the rack 41. When the rack 41 moves downward, it drives the outer wheel 431, which is rotatably connected to the long shaft 44, to rotate. Figure 7 As shown, the outer wheel 431 rotates clockwise at this time. Because a limiting groove is provided inside the outer wheel 431, and the right sidewall of the limiting groove contacts the pawl 432 hinged inside the limiting groove, when the rack 41 moves down, it drives the outer wheel 431 to rotate clockwise. At this time, the pawl 432 cannot drive the inner wheel 433 to rotate. Conversely, when the outer wheel 431 rotates counterclockwise, the limiting groove on the right side of the pawl 432 causes the pawl 432 to engage with the ratchet fixedly connected to the inner wheel 433. That is, the counterclockwise rotating outer wheel 431 can drive the inner wheel 433 fixedly connected to the surface of the long shaft 44 to rotate. Utilizing the principle that the ratchet mechanism 43 can only rotate in one direction and cannot reverse, when the lifting mechanism 3 rises, the ratchet mechanism 43 rotates clockwise, driving the internal fixed connection... The long shaft 44 rotates. To fix the long shaft 44, a fixed plate 42 is rotatably connected to one side of the long shaft 44 and fixedly connected to the outer left wall of the lifting platform 31. A fixed frame 45 is rotatably connected to the other side of the long shaft 44, and a wheel 46 is rotatably connected to the surface of the fixed frame 45. When the ratchet mechanism 43 rotates forward, it drives the long shaft 44 to rotate, which in turn drives the wheel 46 fixedly connected to the long shaft 44 to rotate. When the lifting mechanism 3 descends, the outer surface of the ratchet mechanism 43 meshes with the rack 41 and rotates, while the inside does not rotate. Therefore, it cannot drive the long shaft 44 to rotate. This means that the push mechanism 5 on one side of the lifting mechanism 3 only works when the lifting platform 31 rises and does not work when the lifting platform 31 descends, preventing the push mechanism 5 from interfering with the descending lifting platform 31.

[0095] After the workpiece is extruded, the male mold 1 rises, and the workpiece on the surface of the female mold 2 adheres to the male mold 1. The first spring 32 inside the lifting platform 31 moves upward with the male mold 1 due to its own elasticity, ensuring that the workpiece always adheres to the male mold 1 and preventing the part from springing back. The upward movement of the female mold 2 drives the rack 41 fixedly connected to its side to move, thereby driving the ratchet mechanism 43 to rotate. At this time, the ratchet mechanism 43 rotates counterclockwise, driving the long shaft 44 to move. A slider 54 is fixedly connected to the surface of the wheel 46, and a fixing block 53 is fixedly connected above the fixing frame 45 and close to the side of the wheel 46. The slider 54 is located in the U-shaped groove 531 opened inside the fixing block 53. The wheel 46 rotates counterclockwise with the long shaft 44. The fixed block 53 slides in the U-shaped groove 531, and a connecting rod 55 is fixedly connected to the surface of the fixed block 53. When the fixed block 53 is moved by the slider 54 in the U-shaped groove 531, the connecting rod 55 moves accordingly. The connecting rod 55 drives the connected long rod 56 to move, and the long rod 56 is slidably connected in the fixed frame 45. The fixed frame 45 can support the long rod 56 to move linearly. The long rod 56 pushes the female mold 2 to the left side of the collection box 6. As the lifting platform 31 follows the male mold 1 and slowly rises, it is flush with the inner groove of the collection box 6. At this time, the long rod 56 and the bottom groove of the processed part on the surface of the female mold 2 are aligned. The long rod 56 can push the female mold 2 towards the collection box 6. The electric push rod 57 is parallel to the side wall of the workpiece. A pressure sensor is provided on the contact surface between the long rod 56 and the female mold 2. When the long rod 56 contacts the female mold 2, the electric push rod 57 starts. When the long rod 56 pushes the female mold 2 to the side of the collection box 6, the electric push rod 57 pushes the workpiece into the collection box 6. When the long rod 56 extends, the electric push rod 57 also extends. In order for the long rod 56 to continue working, after the workpiece enters the collection box 6, the lifting platform 31 continues to rise, and the rack 41 drives the ratchet mechanism 43 to continue to rotate, so that the slider 54 rotates counterclockwise from point A to point B on the surface of the wheel 46. The rod 56 retracts to its original position. Two No. 2 springs 51 are fixedly connected between the side wall of the collection box 6 and the female mold 2. After the pushing work is completed, the long rod 56 retracts, and the female mold 2 can retract according to the elastic force of the No. 2 springs 51. A groove 52 is provided between the two No. 2 springs 51 and on the side of the lifting platform 31 to provide space for the movement of the long rod 56. When the lifting platform 31 drives the female mold 2 to rise, the long rod 56 will move inside the groove 52 to prevent the long rod 56 from blocking the movement of the female mold 2. The long rod 56 can work in the groove 52. Due to the action of the ratchet mechanism 43 mentioned above, the pushing mechanism 5 will not work when the lifting platform 31 descends.
