Description

Technical Field

[0001] The present invention relates to the technical field of bending dies, and particularly to a depth flexible control device for an automobile part bending die. Background Art

[0002] In the process of automobile manufacturing, the bending process is a key process for producing parts such as body panels, chassis components, and interior structures. Traditional bending dies are usually designed for fixed angles and depths, and it is difficult to meet the production requirements of parts with different models, materials, or process requirements. With the development of the automobile industry towards flexible production and high-precision manufacturing, die technologies with adjustable bending depths have emerged.

[0003] The depth of existing bending dies is not easy to adjust. The bending angles and depths required for different vehicle models or parts are different. Fixed-depth dies can only be designed for specific parts and cannot quickly switch to produce other models of parts. The curvature differences of body panels (such as car doors and hoods) are relatively large, and single-depth dies are difficult to meet diverse requirements. For each new part produced, the entire set of dies needs to be replaced, resulting in an extended die change time and reduced production efficiency. It is especially not suitable for small-batch or customized production. For this reason, we propose a depth flexible control device for an automobile part bending die to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a depth flexible control device for an automobile part bending die to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A depth flexible control device for an automobile part bending die, including a workbench. A motor is fixedly installed at the lower right end of the workbench. A ball screw is connected to the lower end inside the workbench, and both left and right ends of the ball screw are sleeved with ball screw nuts. The upper end of the ball screw nut is fixedly connected to an adjustment rod, and the other end of the adjustment rod is fixedly connected to a mounting plate. A lower die is fixedly installed at the upper end of the mounting plate. Fixed plates are fixedly connected to both left and right sides of the upper end of the workbench, and a connecting rod is fixedly connected to the upper end of the fixed plate. The other end of the connecting rod is fixedly connected to a fixed frame. Air cylinders are fixedly installed on both left and right sides of the upper end of the fixed frame. A mounting rod is fixedly connected to the lower end of the fixed frame, and an upper die is fixedly installed at the lower end of the mounting rod.

[0006] Preferably, a groove is opened inside the workbench, and the left side of the ball screw is rotationally connected to the inner wall of the workbench, and the right side of the ball screw is fixedly connected to the rotating shaft of the motor.

[0007] Preferably, limiting sliders are fixedly connected to both front and rear ends of the ball screw nut, and sliding grooves matching the limiting sliders are opened on the inner wall of the workbench.

[0008] Preferably, the adjusting rod is composed of two groups of rod bodies in an X-shaped structure, and the middle positions of the two groups of rod bodies are hinged. The upper and lower ends of the adjusting rod are both hinged to the mounting plate and the ball screw sleeve.

[0009] Preferably, a magnetic attraction plate is fixedly connected to the lower surface of the lower die, and a magnet that adsorbs to the magnetic attraction plate is fixedly connected to the upper surface of the mounting plate.

[0010] Preferably, T-shaped blocks are fixedly connected to both the left and right sides of the mounting plate, and T-shaped slots that cooperate with the T-shaped blocks are provided on the inner wall of the workbench.

[0011] Preferably, the lower ends of both the left and right sides of the mounting rod are provided in an L-shaped structure, locking bolts are inserted into both the left and right sides of the lower end of the mounting rod, and locking slots that cooperate with the locking bolts are provided at the upper end of the upper die.

[0012] The present invention provides a depth flexible control device for an automobile part bending die, which has the following beneficial effects:

[0013] By providing a ball screw and a ball screw sleeve, the motor can be turned on. The motor drives the ball screw to rotate through the rotating shaft. At the same time, the ball screw drives the ball screw sleeve to move, so that the two ball screw sleeves move towards each other. The two ball screw sleeves drive the mounting plate to move through the adjusting rod, and the mounting plate drives the lower die to move. Thus, the position of the lower die can be adjusted according to different usage requirements, and the bending depth of the device during use can be adjusted, increasing the adaptability of the device during use.

[0014] By fixedly connecting T-shaped blocks to both the left and right ends of the lower die, when the lower die moves, the T-shaped blocks move with it, and the stability of the lower die during movement can be maintained through the T-shaped blocks, preventing its position from shifting during use.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a depth flexible control device for an automotive part bending die, including a workbench 1, a motor 2 is fixedly installed at the lower right end of the workbench 1, a ball screw 3 is connected to the lower end inside the workbench 1, and ball screw sleeves 4 are sleeved at both the left and right ends of the ball screw 3, and an adjusting rod 5 is fixedly connected to the upper end of the ball screw sleeve 4, the other end of the adjusting rod 5 is fixedly connected to a mounting plate 6, a lower mold 7 is fixedly installed at the upper end of the mounting plate 6, fixing plates 8 are fixedly connected to both the left and right sides of the upper end of the workbench 1, and a connecting rod 9 is fixedly connected to the upper end of the fixing plate 8, the other end of the connecting rod 9 is fixedly connected to a fixing frame 10, cylinders 11 are fixedly installed at both the left and right sides of the upper end of the fixing frame 10, a mounting rod 12 is fixedly connected to the lower end of the fixing frame 10, and an upper mold 13 is fixedly installed at the lower end of the mounting rod 12

[0023] A groove is provided inside the workbench 1, and the left side of the ball screw 3 is rotatably connected to the inner wall of the workbench 1. The right side of the ball screw 3 is fixedly connected to the rotating shaft of the motor 2. The front and rear ends of the ball screw sleeve 4 are fixedly connected with limit sliders. A chute matching the limit sliders is provided on the inner wall of the workbench 1. The adjusting rod 5 is composed of two sets of rod bodies in an X-shaped structure, and the middle positions of the two sets of rod bodies are hinged. The upper and lower ends of the adjusting rod 5 are hinged to the mounting plate 6 and the ball screw sleeve 4 respectively. A magnetic attraction plate is fixedly connected to the lower surface of the lower mold 7. A magnet that adsorbs to the magnetic attraction plate is fixedly connected to the upper surface of the mounting plate 6. T-shaped blocks are fixedly connected to both the left and right sides of the mounting plate 6. T-shaped grooves matching the T-shaped blocks are provided on the inner wall of the workbench 1. The ball screw 3 is driven by the motor 2 to convert rotational motion into linear motion, which has high precision and repeatability and is suitable for scenarios requiring precise positioning (such as mold clamping and stamping alignment). The ball screw 3 has a strong load-bearing capacity and can drive the heavier lower mold 7 or the mounting plate 6 to move smoothly, avoiding deformation or jamming caused by excessive load. The rolling friction characteristic of the ball screw 3 reduces energy loss and extends the service life of the equipment. The limit sliders move along the chute on the inner wall of the workbench 1 to limit the left-right or up-down displacement of the ball screw sleeve 4, ensuring the trajectory stability of the linear motion. The chute and the limit sliders jointly bear the lateral force, preventing the ball screw 3 from bending or twisting due to external forces. The X-shaped adjusting rod 5 can realize the lifting or horizontal movement of the mounting plate 6 by changing the angle between the two sets of rod bodies, adapting to molds or materials of different thicknesses. The lower mold 7 is fixedly connected to the mounting plate 6 by the magnetic attraction between the magnetic attraction plate and the magnet on the mounting plate 6, without the need for screws or clamps, and can be assembled or replaced by hand. The magnet provides sufficient adsorption force to ensure that the lower mold 7 will not detach from the equipment during operation due to vibration or tilting. The magnetic adsorption connection avoids the shear force when the screws are tightened, preventing scratches or deformation on the mold surface. The T-shaped blocks can increase the stability of the lower mold 7 during movement and prevent it from shaking.

[0024] The lower left and right sides of the lower end of the mounting rod 12 are both arranged in an L-shaped structure. Locking bolts are inserted into the lower left and right sides of the lower end of the mounting rod 12. Locking grooves matching the locking bolts are provided at the upper end of the upper mold 13. The L-shaped structure at the lower end of the mounting rod 12 increases the contact area with the upper mold 13, forming a double-point support, effectively resisting the lateral torsional force of the upper mold 13 during the mold clamping process. The vertical part of the L-shaped structure can serve as a guide post to ensure that the upper mold 13 moves vertically along the mounting rod 12, avoiding tilting or deviation. After the locking bolts are inserted into the locking grooves of the upper mold 13, the horizontal and rotational degrees of freedom of the upper mold 13 are restricted, ensuring that the upper and lower molds 7 are completely aligned during mold clamping. The tight fit between the locking bolts and the locking grooves prevents the upper mold 13 from detaching from the mounting rod 12 due to vibration or impact during equipment operation, facilitating the replacement of the upper mold 13.

[0025] Working principle: Turn on the motor 2. The motor 2 drives the ball screw 3 to rotate through the rotating shaft. The ball screw 3 drives the adjusting rod 5 to move through the ball screw sleeve 4. The adjusting rod 5 drives the mounting plate 6 and the lower mold 7 to move to a suitable position. Then turn off the motor 2. The locking bolt can be pulled out to replace the upper mold 13. Turn on the cylinder 11. The cylinder 11 drives the upper mold 13 to perform the bending work through the fixed frame 10.
