Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to a rolling die for automotive anti-collision tubes. Background Technology

[0002] The automotive crash barrier rolling forming mold is a key piece of equipment used to roll sheet metal into automotive crash barriers. In the existing technology, a side mold consisting of a mold base, mold frame, side mold, auxiliary mold and push block is used to roll it into a roll shape. The side mold reset operation is mainly controlled by a spring.

[0003] However, under prolonged use, the spring will gradually lose its elasticity due to repeated stress exceeding its fatigue limit. As a result, the side mold controlled by the spring may not move properly, leading to incomplete rolling of the sheet metal during the subsequent rolling process. This affects the forming quality of the automotive crash barrier tube. To address the shortcomings of existing technology, we propose an automotive crash barrier tube rolling forming mold to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rolling forming mold for automotive crash barriers. This solves the problem that when springs are subjected to repeated stress exceeding their fatigue limit over long periods of use, microcracks develop inside, causing the springs to gradually lose elasticity. Consequently, the side mold controlled by the spring may not move properly, resulting in incomplete rolling of the sheet metal during subsequent rolling processing, thus affecting the forming quality of the automotive crash barrier.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling forming mold for automotive anti-collision tubes, comprising a mold base, a stand, a hydraulic cylinder, a slide rail, a side mold, a spring, a moving frame, an auxiliary mold, and a pushing block.

[0007] A groove is formed inside the slider. Two sets of clamping plates are slidably arranged inside the groove. A bidirectional threaded rod for clamping and fixing the two sets of clamping plates and the guide rod is rotatably connected inside the groove.

[0008] A drive motor is located on one side of the slider and connected to one end of a bidirectional threaded rod;

[0009] An electric telescopic rod is installed on the side of the mold base, and one end of the electric telescopic rod is fixedly connected to one end of the guide rod.

[0010] Preferably, a hollow box for supporting the drive motor is fixedly connected to the side of the slider.

[0011] Preferably, the top surfaces of both sets of clamps are fixedly connected to limit blocks, which slide within the inner wall of the groove.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This application provides a rolling forming mold for automotive crash barriers, which solves the problem that when a spring is subjected to repeated stress exceeding its fatigue limit after long-term use, microcracks develop inside, causing the spring to gradually lose its elasticity. As a result, the side mold controlled by the spring may not move to the correct position, leading to incomplete rolling of the sheet metal during subsequent rolling processing, thus affecting the forming quality of the automotive crash barrier. This invention enables the adjustment of the side mold position based on the spring.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This utility model discloses a rolling forming mold for automotive anti-collision pipes.

[0031] According to the appendix Figure 1-7As shown, the assembly includes a mold base 1, a support frame 11 fixedly mounted on the top surface of the mold base 1, a hydraulic cylinder 12 fixedly mounted on the top surface of the support frame 11, a slide rail 2 formed on the top surface of the mold base 1, a side mold 3 that slides along the slide rail 2, a spring 31 set inside the slide rail 2 for elastic movement of the side mold 3, a movable frame 4 slidably mounted on the outer wall of the support frame 11, an auxiliary mold 5 set on the bottom surface of the movable frame 4, and a push block 6. One end of the hydraulic cylinder 12 is fixedly connected to the top surface of the movable frame 4. Specifically, when rolling the automotive anti-collision tube, the sheet material is first placed... On the top surface of the mold base 1, one end of the plate-shaped material contacts the arc-shaped wall of the side mold 3. The plate-shaped material is then clamped and fixed by the fixture on the mold base 1. Next, the hydraulic cylinder 12 is activated, pushing the moving frame 4, the auxiliary mold 5 located on the bottom surface of the moving frame 4, and the pushing block 6 downwards. When the pushing block 6 contacts the inclined surface of the side mold 3, the side mold 3 moves towards the plate-shaped material via the compression spring 31 under the pushing of the pushing block 6. Simultaneously, the auxiliary mold 5 remains in a downward-moving state. When the side mold 3 and the auxiliary mold 5 move to the position shown in the attached diagram... Figure 1 When the plate material is in the state of forming a circular space, the part of the plate material located inside the circular space is rolled up, thereby completing the forming of the car anti-collision tube. Finally, the hydraulic cylinder 12 drives the moving frame 4 and the auxiliary mold 5 and the pushing block 6 set on the bottom surface of the moving frame 4 to move upward. At this time, the pressure on the side mold 3 disappears, and the side mold 3 moves away from the plate material under the elastic force of the spring 31, so that the car anti-collision tube formed on the top surface of the mold base 1 is exposed.

[0032] See attached document Figure 2-7 The slide 2 is equipped with an adjustment mechanism 7, which allows for further position adjustment of the side mold 3. The adjustment mechanism 7 includes guide rods 71, with two sets of guide rods 71 ​​disposed inside the slide 2. A slider 72, connected to the side mold 3, is slidably connected to the outer wall of the two sets of guide rods 71. A groove 73 is formed inside the slider 72, and two sets of clamping plates 74 are slidably disposed inside the groove 73. A bidirectional threaded rod 75 is rotatably connected inside the groove 73 for clamping and fixing the two sets of clamping plates 74 and the guide rods 71. The outer wall of the bidirectional threaded rod 75 has two sets of threaded grooves. With opposite directions of the grooves, one end of each of the two sets of clamping plates 74 is threaded onto the outer wall of the bidirectional threaded rod 75, which has a set of threaded grooves. This allows the two sets of clamping plates 74 to move to the sides or to the center simultaneously when the bidirectional threaded rod 75 is rotated. The top surfaces of the two sets of clamping plates 74 are fixedly connected to limit blocks 741, which slide in a limited manner on the inner wall of the groove 73. The side of each set of clamping plates 74 near the guide rod 71 is fixedly connected to an anti-slip layer 9. The drive motor 76 is located on one side of the slider 72 and connected to one end of the bidirectional threaded rod 75. The side of the slider 72 is fixedly connected to a hollow box 721 for supporting the drive motor 76.

[0033] See attached document Figure 2 and attached Figure 7 The electric telescopic rod 77 is set on the side of the mold base 1. One end of the electric telescopic rod 77 is fixedly connected to one end of the guide rod 71. The end of the guide rod 71 away from the electric telescopic rod 77 is fixedly connected to the positioning telescopic rod 78. The other end of the positioning telescopic rod 78 is fixedly connected to the inner wall of the slide 2.

[0034] See attached document Figure 2 and attached Figure 4 A mounting base 8 for supporting the side mold 3 is fixedly connected to one side of the slider 72. One end of the mounting base 8 is limited to slide inside the slide rail 2. A locking piece 81 is fixedly connected to the bottom surface of the side mold 3. The locking piece 81 is snapped into the inside of the mounting base 8. A locking screw 82 for locking the locking piece 81 and the mounting base 8 is rotatably connected to one side of the mounting base 8. The auxiliary mold 5 and the push block 6 are fixedly connected to the moving frame 4 through the locking screw 82, so that the side mold 3, the auxiliary mold 5 and the push block 6 can be replaced as needed.

[0035] Specifically, when the spring 31 gradually loses its elasticity due to repeated stress exceeding its fatigue limit, the side mold 3 may not move to the correct position during the resetting process. In this case, the drive motor 76 is activated first, causing it to control the bidirectional threaded rod 75 to rotate. This, in turn, controls the two sets of clamping plates 74 to clamp and fix them to the outer wall of the guide rod 71. At this time, the slider 72 is in a fixed connection with the two sets of guide rods 71. Then, the electric telescopic rod 77 is activated, so that with the assistance of the positioning telescopic rod 78, the guide rod 71 and the slider 72 fixedly connected to the guide rod 71 slide inside the slide rail 2. This causes the side mold 3, which is fixedly connected to the slider 72 through the mounting base 8, to slide along the slide rail 2. Based on the control of the spring 31, the position of the side mold 3 can be further adjusted to ensure that the side mold 3 moves the required distance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
