A rotating shaft is provided on the outer surface of the support frame, penetrating the support frame and rotatably connected to it. A fixed roller is fixed to the rotating shaft, and a sliding roller is slidably connected to the rotating shaft. In this cold bending forming machine with adjustable roll width, by using a limiting component, when the position of the sliding roller is adjusted, rotating the rotating plate causes the ring to rotate synchronously via a connecting rod, causing the groove and the contact rod to intersect.

The sliding roller cannot move further, ensuring its stable position and preventing displacement during equipment operation, which would affect subsequent normal processing. Simultaneously, the movable column engages with the stabilizing groove to prevent the rotating plate from rotating on its own, enhancing the stability of the ring.

Description

Technical Field

[0001] This utility model relates to the field of cold bending forming machine technology, specifically a cold bending forming machine with adjustable roll width. Background Technology

[0002] A cold bending forming machine is a machine that uses sequentially arranged multi-pass forming rollers to continuously bend metal sheets and strips laterally to produce profiles with specific cross-sections.

[0003] According to a cold bending forming machine with adjustable roll width and its working method disclosed in the above application (Publication No.: CN113617895A), when the movable roll body and the fixed roll body are in contact, the limiting post and the clamping plate can be inserted into the limiting hole and the clamping groove respectively, so as to firmly connect the fixed roll body and the movable roll body together and avoid relative rotation during processing.

[0004] However, the aforementioned application relies solely on the connecting spring for stabilization. In actual operation, dynamic loads generated by equipment vibration, high-speed rotation of the rolls, and bending of the metal strip may render the spring's restoring force insufficient to maintain a stable connection, leading to unexpected separation or slight displacement between the movable and fixed rolls. This instability not only affects forming accuracy but may also cause equipment malfunctions, reduce production efficiency, and even pose safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a cold bending forming machine with adjustable roll width to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cold bending forming machine with adjustable roll width, comprising a support frame, a rotating shaft provided on the outer surface of the support frame, the rotating shaft passing through the support frame and being rotatably connected to the support frame, a fixed roller passing through and fixedly mounted on the rotating shaft, and a sliding roller passing through and slidably connected on the rotating shaft, wherein the sliding roller and the outer surface and interior of the rotating shaft are provided with adjustment components and limiting components;

[0007] The limiting component includes:

[0008] Circular rings are used for positioning and to improve stability.

[0009] The connecting rod is used to drive the ring to rotate synchronously.

[0010] The rotating plate is used to drive the connecting rod and the ring to rotate synchronously.

[0011] Preferably, the adjusting assembly includes a cavity located inside the sliding roller. A fixing rod is fixed to the inner wall of the cavity. A limiting block is provided inside the cavity, and a groove is formed on the outer surface of the limiting block. The fixing rod is slidably connected to the inner wall of the groove. A spring is fixed to the outer surface of the limiting block, with the end of the spring away from the limiting block fixed to the inner wall of the cavity. A limiting groove is formed on the outer surface of the rotating shaft, and an abutment rod is fixed to the outer surface of the limiting block. Pulling the sliding roller towards or near the fixed roller causes the rotating plate to disengage from the receiving groove. The limiting block slides along the limiting groove, causing the abutment rod to move into the groove of the annulus, while simultaneously compressing the spring. When the limiting block moves to a position aligned with the next limiting groove, the spring releases, pushing the limiting block into the new limiting groove. This does not affect the normal movement of the sliding roller and prevents the sliding roller from shifting on its own. Simultaneously, the fixing rod reciprocates along the groove, ensuring smooth movement of the limiting block, thereby completing the width adjustment.

[0012] Preferably, the ring is rotatably connected to the inner wall of the cavity. A connecting rod is fixed to the outer surface of the ring, and an arc-shaped hole is formed on the outer surface of the sliding roller. The end of the connecting rod away from the ring passes through the arc-shaped hole, and a rotating plate is fixed to the end of the connecting rod away from the ring. A movable groove is formed on the outer surface of the rotating plate, and a movable column is slidably connected to the inner wall of the movable groove. A second spring is fixed to the outer surface of the movable column, and the end of the second spring away from the movable column is fixed to the inner wall of the movable groove. A stabilizing groove is formed on the side of the sliding roller near the rotating plate, and a receiving groove is formed on the side of the sliding roller away from the rotating plate. A groove is formed on the inner side of the ring. Rotating the rotating plate drives the ring to rotate synchronously through the connecting rod. The groove and the contact rod are staggered, and the inner side of the ring fits against the outer surface of the contact rod, restricting the movement of the contact rod and the limiting block, ensuring the stability of the sliding roller, and preventing displacement during equipment operation. At the same time, the movable column is engaged in the stabilizing groove to prevent the rotating plate from rotating on its own, enhancing the stability of the ring.

[0013] Preferably, a gear is passed through and fixed at the right end of the rotating shaft. The rotating shaft, fixed roller, sliding roller, and gear are arranged symmetrically from top to bottom. A motor is connected to the surface of one set of gears. When the motor is started, the fixed roller can be rotated, thus processing the sheet material.

[0014] Preferably, the cross-section of the end of the limiting block away from the spring is triangular. When it moves with the sliding roller, its surface abuts against the inner wall of the limiting groove, which allows the limiting block to move away from the rotating shaft without affecting the normal movement of the sliding roller, and facilitates the adjustment of the width to use plates of different widths.

[0015] Preferably, the end of the movable column away from the movable groove is set to an arc shape, so that when it comes into contact with the inner wall of the stabilizing groove, the movable column can move into the movable groove without affecting the normal rotation of the rotating plate.

[0016] Preferably, the stabilizing groove is provided in two sets to facilitate the stabilization of the rotating plate.

[0017] Compared with the prior art, this utility model provides a cold bending forming machine with adjustable roll width, which has the following beneficial effects:

[0018] 1. This cold bending forming machine with adjustable roll width, through a set limiting component, allows the rotating plate to rotate when the sliding roll position is adjusted. This rotation, via a connecting rod, drives the ring to rotate synchronously, causing the groove and the contact rod to intersect. At this point, the inner side of the ring is in contact with the outer surface of the contact rod, thus limiting the contact rod and the limiting block. The sliding roll cannot move further, ensuring its stable position and preventing displacement during operation, which could affect subsequent processing. Simultaneously, the movable column engages with the stabilizing groove to prevent the rotating plate from rotating on its own, enhancing the stability of the ring.

[0019] 2. This cold bending forming machine with adjustable roll width, through its adjustable components, allows for width adjustment. When the processing width needs to be adjusted, the sliding roll is pulled towards or near the fixed roll. The outer surface of the limiting block abuts against the inner wall of the limiting groove, and the abutting rod moves into the groove, simultaneously compressing spring one. When the limiting block moves to a position aligned with the next limiting groove, spring one is released, pushing the limiting block into the new limiting groove. This does not affect the normal movement of the sliding roll and prevents the sliding roll from shifting on its own, thus allowing for width adjustment to accommodate sheets of different widths.

[0030] like Figures 1-9 As shown, this utility model provides a technical solution: a cold bending forming machine with adjustable roll width, including a support frame 1, a rotating shaft 2 is provided on the outer surface of the support frame 1, the rotating shaft 2 passes through the support frame 1 and is rotatably connected to the support frame 1, a fixed roller 3 passes through and is fixed thereon on the rotating shaft 2, and a sliding roller 4 passes through and is slidably connected thereon on the rotating shaft 2. An adjustment component 6 and a limiting component 7 are provided on the outer surface and inside of the sliding roller 4 and the rotating shaft 2; the limiting component 7 includes: a ring 70, a connecting rod 71, a rotating plate 72, an arc-shaped hole 73, a movable groove 74, a movable column 75, a spring 76, a stabilizing groove 77, a receiving groove 78, and a recess 79.

[0031] A circular ring 70 is rotatably connected to the inner wall of the cavity 60. A connecting rod 71 is fixed to the outer surface of the circular ring 70. An arc-shaped hole 73 is opened on the outer surface of the sliding roller 4. The end of the connecting rod 71 away from the circular ring 70 passes through the arc-shaped hole 73. A rotating plate 72 is fixed to the end of the connecting rod 71 away from the circular ring 70. A movable groove 74 is opened on the outer surface of the rotating plate 72. A movable column 75 is slidably connected to the inner wall of the movable groove 74. A second spring 76 is fixed to the outer surface of the movable column 75. The second spring 76 is slidably connected to the inner wall of the movable column 60. One end of the column 75 is fixed to the inner wall of the movable groove 74. A stabilizing groove 77 is provided on the side of the sliding roller 4 closest to the rotating plate 72, and a receiving groove 78 is provided on the side of the sliding roller 4 furthest from the rotating plate 72. A groove 79 is provided on the inner side of the ring 70. The end of the movable column 75 furthest from the movable groove 74 is arc-shaped. Two sets of stabilizing grooves 77 are provided. When the sliding roller 4 is in contact with the outer surface of the fixed roller 3 or other sliding rollers 4, rotating the rotating plate 72 will drive the ring 70 to rotate synchronously via the connecting rod 71. At this time, the groove 79 and the contact rod 66 are staggered, and the inner side of the ring 70 is in contact with the outer surface of the contact rod 66, thereby restricting the movement of the contact rod 66 and the limiting block 62, ensuring the stability of the sliding roller 4, and preventing displacement during equipment operation. During the rotation of the rotating plate 72, the movable column 75 is pressed into the movable groove 74, and the second spring 76 is compressed. When the movable column 75 aligns with another set of stabilizing grooves 77, the second spring 76 is released, pushing the movable column 75 into the stabilizing groove 77, preventing the rotating plate 72 from rotating on its own and enhancing the stability of the ring 70. When further width adjustment is needed, the above steps are repeated, and the rotating plate 72 can be stored in the receiving groove 78 to avoid interfering with normal operation.

[0032] The adjusting assembly 6 includes a cavity 60, which is located inside the sliding roller 4. A fixing rod 61 is fixed to the inner wall of the cavity 60. A limiting block 62 is provided inside the cavity 60, and a groove 64 is formed on the outer surface of the limiting block 62. The fixing rod 61 is slidably connected to the inner wall of the groove 64. A spring 63 is fixed to the outer surface of the limiting block 62, and the end of the spring 63 away from the limiting block 62 is fixed to the inner wall of the cavity 60. A limiting groove 65 is formed on the outer surface of the rotating shaft 2, and an abutment rod 66 is fixed to the outer surface of the limiting block 62. The cross-section of the end of the limiting block 62 away from the spring 63 is triangular. When processing plates of different widths, the sliding roller 4 is pulled towards the fixed roller 3, and the rotating plate 72 is disengaged from the receiving groove 78. At this time, the limiting block 62 slides along the limiting groove 65, causing the abutment rod 66 to move into the groove 79 of the ring 70, while compressing the spring 63. When the limiting block 62 moves to a position aligned with the next limiting groove 65, the spring 63 is released, pushing the limiting block 62 into the new limiting groove 65, while the abutment rod 66 disengages from the groove 79. During this process, the fixing rod 61 reciprocates along the slide groove 64 to ensure that the limiting block 62 moves smoothly, thereby completing the width adjustment to meet the processing requirements of different sized plates.

[0033] A gear 5 is fixed through and fixed to the right end of the rotating shaft 2. The rotating shaft 2, fixed roller 3, sliding roller 4, and gear 5 are arranged symmetrically from top to bottom. The surface of one set of gears 5 is connected to a motor. The plate is placed between the fixed rollers 3, and the upper and lower gears 5 mesh at the same time. When the motor is started, the fixed roller 3 can be rotated, and the plate can be processed.

[0034] In use, the sheet material is placed between the fixed rollers 3, and the upper and lower gears 5 mesh simultaneously. Starting the motor causes the fixed rollers 3 to rotate, allowing for the processing of the sheet material. When dealing with sheets of different widths, the sliding roller 4 is pulled closer to the fixed roller 3. At this time, the rotating plate 72 disengages from the receiving groove 78. Simultaneously, as the sliding roller 4 moves, the outer surface of the limiting block 62 abuts against the inner wall of the limiting groove 65. The limiting block 62 then moves away from the rotating shaft 2, simultaneously moving the contact rod 66 into the groove 79, compressing the spring 63. When the limiting block 62 is parallel to the limiting groove 65, the spring 63 releases, and the limiting block 62 enters the limiting groove 65. The contact rod 66 disengages from the groove 79, and the fixed rod 61 reciprocates into the sliding groove 64, stabilizing the movement of the limiting block 62. This allows for width adjustment, facilitating the processing of different sheet materials. When the sliding roller 4 is in contact with the outer surface of the fixed roller 3 or other sliding rollers 4... At this time, rotating the rotating plate 72 causes the ring 70 to rotate synchronously via the connecting rod 71, so that the groove 79 and the contact rod 66 are staggered. At the same time, the inner side of the ring 70 is in contact with the outer surface of the contact rod 66, which limits the contact rod 66 and the limiting block 62, preventing the sliding roller 4 from moving further and avoiding affecting the position and stability of the sliding roller 4 during operation. Meanwhile, when the rotating plate 72 rotates, the outer surface of the movable column 75 abuts against the inner wall of the stabilizing groove 77, causing the movable column 75 to move into the movable groove 74. At the same time, the second spring 76 is compressed. When the movable column 75 is parallel to another set of stabilizing grooves 77, the second spring 76 is released, driving the movable column 75 into the stabilizing groove 77. This prevents the rotation of the rotating plate 72 from affecting the position of the ring 70 and improves the stability of the ring 70. When the width is further increased, the above steps are repeated, and the rotating plate 72 enters the receiving groove 78 without affecting the normal bonding.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
