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 bending angle. 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. It is widely used in the field of machining.

[0003] Currently, traditional cold bending forming machines adjust the bending angle by rotating a screw to control the distance between the pressure roller and the support roller. However, this adjustment relies on the operator's subjective judgment and lacks an auxiliary adjustment structure, making it easy for deviations to occur during adjustment. Therefore, we propose a cold bending forming machine with adjustable bending angle. Utility Model Content

[0004] The purpose of this invention is to provide a cold bending forming machine with an adjustable bending angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold bending forming machine with adjustable bending angle, comprising a machine body and a U-shaped frame fixed to the top of the machine body. A bending mechanism is provided on the inner side of the U-shaped frame. The bending mechanism consists of two sets of drive blocks, pressure rollers, and support rollers. An adjustment control mechanism is provided on the U-shaped frame. The adjustment control mechanism consists of a control part and a limiting part. The limiting part includes:

[0006] Lifting blocks are used to limit drive blocks;

[0007] Fixed teeth and fixed blocks are used to cooperate with movable teeth to support the lifting block;

[0008] The control component is used to control the movement of the movable jaw teeth.

[0009] Preferably, the two sets of drive blocks are slidably installed on the inside of the U-shaped frame. The output shaft of one set of drive blocks is fixed to the pressure roller, and the output shaft of the other set of drive blocks is fixed to the support roller. The drive block is a drive motor that slides inside the U-shaped frame through its housing. The control unit can control the movement of the drive block at the top to adjust the distance between the pressure roller and the support roller, thereby adjusting the bending angle. The two sets of drive blocks drive the pressure roller and the support roller to rotate.

[0010] Preferably, the fixed locking teeth are fixed to the front of the U-shaped frame, the lifting block is slidably mounted on the front of the U-shaped frame, the movable locking teeth penetrate the side of the lifting block and are slidably connected to the lifting block, the control component is set on the lifting block, the fixed locking teeth are provided with a scale on the front, the lifting block is fixed with a pointer on the front, the movable locking teeth and the fixed locking teeth engage, unidirectionally restricting the lifting block so that the lifting block cannot move downwards, thereby the lifting block can lift the driving block at the top, so that when adjusting the driving block to move downwards, the driving block can only move to the position of the lifting block and then stop, which plays an auxiliary adjustment function, avoids deviation during adjustment, and can adjust the bending angle as needed, and adjust the height of the lifting block according to the pointer and scale, thereby restricting the adjustment of the distance between the two sets of driving blocks.

[0011] Preferably, the control component includes a grip rod that passes through the lifting block and is fixed to the inner wall of the lifting block. A telescopic rod is fixed to the end of the movable locking tooth away from the fixed locking tooth. The end of the telescopic rod away from the movable locking tooth is fixed to the grip rod. A return spring is provided between the telescopic rod and the grip rod. A control rod is fixed to the outer wall of the telescopic rod, and the control rod passes through the lifting block. When the lifting block is moved upwards, the inclined surface of the movable locking tooth abuts against the inclined surface of the fixed locking tooth, causing the movable locking tooth to... Moving the lifting block within the block does not affect its upward movement. When the lifting block moves downward under force, the vertical surfaces of the movable locking teeth abut against the vertical surfaces of the fixed locking teeth, thus restricting the lifting block's downward movement. To control the lifting block's downward movement, simply squeeze the control lever and move it towards the grip. The control lever will then retract the movable locking teeth into the lifting block via the telescopic rod, and the movable locking teeth will no longer engage with the fixed locking teeth. At this point, the lifting block can be controlled to move downward, making it convenient to use.

[0012] Preferably, the control unit includes a fixing frame, which is fixed to the top of the U-shaped frame. A nut is fixed to the top of the fixing frame, and the nut is threadedly connected to a screw. The screw passes through the U-shaped frame and the fixing frame, and the bottom of the screw is rotatably mounted on the top of the drive block. By rotating the screw, the drive block at the top can be controlled to move downward, thereby adjusting the gap between the pressure roller and the support roller.

[0013] Compared with the prior art, this utility model provides a cold bending forming machine with an adjustable bending angle, which has the following beneficial effects:

[0014] 1. This cold bending forming machine with adjustable bending angle, through its control and limiting parts, restricts the lifting block in one direction when adjusting the pressure roller by engaging the movable and fixed locking teeth, preventing the lifting block from moving downwards. This allows the lifting block to support the drive block at the top, ensuring that when adjusting the drive block to move downwards, it can only move to the position of the lifting block and then stop, thus providing auxiliary adjustment and preventing deviations during adjustment.

[0015] 2. This cold bending forming machine with adjustable bending angle features a movable locking tooth that abuts against the fixed locking tooth when the lifting block moves upward. This allows the movable locking tooth to move inward without affecting the upward movement of the lifting block. When the lifting block moves downward under force, the vertical surface of the movable locking tooth abuts against the vertical surface of the fixed locking tooth, thus restricting the lifting block and preventing it from moving downward. To control the downward movement of the lifting block, simply squeeze the control lever and move it towards the grip. The control lever will then retract the movable locking tooth into the lifting block via the telescopic rod, and the movable locking tooth will no longer engage with the fixed locking tooth. At this point, the lifting block can be controlled to move downward, making it convenient to use. Attached Figure Description

[0022] like Figures 1-5As shown, this utility model provides a technical solution: a cold bending forming machine with adjustable bending angle, including a machine body 1 and a U-shaped frame 2 fixed on the top of the machine body 1. A bending mechanism 5 is provided on the inner side of the U-shaped frame 2. The bending mechanism 5 consists of two sets of drive blocks 51, pressure rollers 52 and support rollers 53. An adjustment control mechanism is provided on the U-shaped frame 2. The adjustment control mechanism consists of a control part 3 and a limiting part 4. The limiting part 4 includes: a lifting block 41, a fixed locking tooth 42, a movable locking tooth 43, a control component 44, a scale 45, and a pointer 46.

[0023] Two sets of drive blocks 51 are slidably installed on the inside of the U-shaped frame 2. The output shaft of one set of drive blocks 51 is fixed to the pressure roller 52, and the output shaft of the other set of drive blocks 51 is fixed to the support roller 53. The drive block 51 is a drive motor that slides inside the U-shaped frame 2 through its housing. The control unit 3 can control the drive block 51 at the top to move and adjust the distance between the pressure roller 52 and the support roller 53, thereby adjusting the bending angle. The two sets of drive blocks 51 drive the pressure roller 52 and the support roller 53 to rotate.

[0024] The fixed locking teeth 42 are fixed to the front of the U-shaped frame 2, and the lifting block 41 is slidably installed on the front of the U-shaped frame 2. The movable locking teeth 43 penetrate through the side of the lifting block 41 and are slidably connected to the lifting block 41. The control component 44 is set on the lifting block 41. The fixed locking teeth 42 is provided with a scale 45 on the front, and the lifting block 41 is fixed with a pointer 46 on the front. The movable locking teeth 43 and the fixed locking teeth 42 engage to restrict the lifting block 41 in one direction, so that the lifting block 41 cannot move downward. Thus, the lifting block 41 can lift the driving block 51 at the top, so that when adjusting the driving block 51 to move downward, the driving block 51 can only move to the position of the lifting block 41 and then stop. This plays an auxiliary adjustment function, avoids deviation during adjustment, and can adjust the bending angle as needed. The height of the lifting block 41 can be adjusted according to the pointer 46 and the scale 45, thereby restricting the adjustment of the distance between the two sets of driving blocks 51.

[0025] The control component 44 includes a grip rod 441 that passes through the lifting block 41 and is fixed to the inner wall of the lifting block 41. A telescopic rod 442 is fixed to the end of the movable locking tooth 43 away from the fixed locking tooth 42. The end of the telescopic rod 442 away from the movable locking tooth 43 is fixed to the grip rod 441. A return spring 443 is provided between the telescopic rod 442 and the grip rod 441. A control rod 444 is fixed to the outer wall of the telescopic rod 442 and passes through the lifting block 41. When the lifting block 41 is moved upwards, the inclined surface of the teeth of the movable locking tooth 43 abuts against the inclined surface of the teeth of the fixed locking tooth 42, causing the movable locking tooth 43 to... Moving the lifting block 41 into the lifting block 41 does not affect its upward movement. When the lifting block 41 moves downward under force, the vertical surface of the teeth of the movable locking tooth 43 abuts against the vertical surface of the teeth of the fixed locking tooth 42, thereby restricting the lifting block 41 and preventing it from moving downward. When it is necessary to control the lifting block 41 to move downward, simply squeeze the control lever 444 to move it closer to the grip lever 441. The control lever 444 can then retract the movable locking tooth 43 into the lifting block 41 via the telescopic rod 442. The movable locking tooth 43 will no longer engage with the fixed locking tooth 42, and the lifting block 41 can then be controlled to move downward. This method is convenient to use.

[0026] The control unit 3 includes a fixing frame 31, which is fixed to the top of the U-shaped frame 2. A nut 32 is fixed to the top of the fixing frame 31. The nut 32 is threadedly connected to a screw 33. The screw 33 passes through the U-shaped frame 2 and the fixing frame 31. The bottom of the screw 33 is rotatably mounted on the top of the drive block 51. By rotating the screw 33, the drive block 51 at the top can be controlled to move downward, thereby adjusting the gap between the pressure roller 52 and the support roller 53.

[0027] In this invention, when the bending angle needs to be adjusted, the control lever 444 is squeezed to move closer to the grip lever 441, controlling the movable locking tooth 43 to separate from the fixed locking tooth 42, and controlling the lifting block 41 to move up or down. The position of the lifting block 41 is adjusted according to the position of the pointer 46 pointing to the scale 45. After adjustment, the control lever 444 is released. Under the action of the return spring 443, the telescopic rod 442, along with the movable locking tooth 43, returns to its original position and re-engages with the fixed locking tooth 42. The vertical surface of the teeth of the movable locking tooth 43 abuts against the vertical surface of the teeth of the fixed locking tooth 42, thereby restricting the lifting block 41 and preventing it from moving downward.

[0028] At this point, the screw 33 can be rotated to control the drive block 51 at the top to move downward, thereby adjusting the distance between the pressure roller 52 and the support roller 53 and thus adjusting the bending angle.

[0029] 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.
