The U-shaped support frame 2 is U-shaped with its opening facing downwards, possessing good structural stability, and is used to support components such as a hydraulic cylinder 3. A hydraulic cylinder 3 is fixedly connected to the top of the U-shaped support frame 2. The hydraulic cylinder 3 is a linear reciprocating motion actuator that can output stable hydraulic driving force.

The hydraulic rod 4 is driven by the hydraulic cylinder 3 and can extend and retract vertically, transmitting the power of the hydraulic cylinder 3. A bending assembly 5 is fixedly connected to the bottom of the hydraulic rod 4. The bending assembly 5 is used to perform the bending operation on the copper-clad laminate and moves synchronously with the hydraulic rod 4. Two constraint components 6 are fixedly connected to the top of the base 1. The two constraint components 6 are symmetrically distributed on the top of the base 1 to constrain the copper-clad laminate from the horizontal direction and prevent it from shifting when bent. A mold component 8 is fixedly connected to the top of the base 1. The mold component 8 is a forming mold for bending the copper-clad laminate and provides the surface support required for bending. A slide groove 7 is opened on the top of the base 1. The slide groove 7 provides a guide track for the sliding of the mold component 8. It is long and strip-shaped and adapts to the sliding requirements of the mold body 81. The horizontally distant side of the two constraint components 6 is set inside the U-shaped support frame 2. That is, part of the structure of the constraint component 6 is within the space surrounded by the U-shaped support frame 2, making reasonable use of the space layout. The bottom of the bending component 5 is set on the top of the mold component 8. The bottom of the bending component 5 cooperates with the top of the mold component 8 to bend the copper-clad laminate placed on the mold component 8. The mold assembly 8 includes a mold body 81, which serves as the main load-bearing structure for mounting components such as the semi-cylinders 82. The mold body 81 is externally slidably connected to the interior of a slide groove 7, allowing it to slide along the length of the slide groove 7 for easy adjustment of the working position of the mold assembly 8. Two semi-cylinders 82 are slidably connected to the top of the mold body 81. These two semi-cylinders 82 can be joined to form cylindrical surfaces of different diameters, providing an arc-shaped support surface for bending the copper-clad laminate. They can slide on the top of the mold body 81 to accommodate copper-clad laminates of different specifications. Adjusting columns 84 are fixedly connected to both sides of the semi-cylinders 82. These cylindrical adjusting columns 84 are used to connect compression springs 85, transmitting the elastic force of the springs. Compression springs 85 are fixedly connected to the outside of the adjusting columns 84. These compression springs 85 have elastic extension and contraction characteristics, applying an elastic preload to the semi-cylinders 82 to assist in their reset and position adjustment. The ends of the compression springs 85 are fixedly connected to the outside of the mold body 81, allowing the elastic force of the compression springs 85 to act on the mold body 81 and the semi-cylinders 82. Between the cylinders 82, to maintain the stable position of the semi-cylinders 82, two tightening bolts 83 are threadedly connected to both sides of the outer side of the mold body 81. The tightening bolts 83 are detachable connectors. By screwing them into the mold body 81, they can press against the semi-cylinders 82 to fix their position. The two tightening bolts 83 are positioned on the outer side of the semi-cylinders 82 at a close distance. When tightened, the ends of the tightening bolts 83 contact the outer wall of the semi-cylinders 82, generating a tightening force to restrict the sliding of the semi-cylinders 82. The bottom outer side of the mold body 81 is fixed. The fixed connection has two fixing blocks 86. The fixing blocks 86 are block-shaped structures with threaded holes adapted to the expansion positioning pins 87 for installing the expansion positioning pins 87.

The expansion positioning pins 87 are connected to the fixing blocks 86 and the base 1 through threads, which can lock the position of the mold body 81 in the slide groove 7. The external threads of the expansion positioning pins 87 are connected to the inner side of the base 1, realizing the relative fixation of the mold body 81 and the base 1, and ensuring the working stability of the mold assembly 8.
[0013] Reference Figure 1 , Figure 2 , Figure 4The bending assembly 5 includes a U-shaped mounting plate 51, which is U-shaped with its opening facing left, providing installation space and sliding guidance for the bending plate 52. The top of the U-shaped mounting plate 51 is fixedly connected to the bottom of the hydraulic rod 4, and moves up and down with the hydraulic rod 4, driving the bending assembly 5 to move as a whole. The bending plate 52 is slidably connected to the inner side of the U-shaped mounting plate 51, and the bending plate 52 can slide inside the U-shaped mounting plate 51, facilitating the replacement of different specifications to adapt to various bending needs. The bottom of the U-shaped mounting plate 51 is threaded with multiple locking bolts 53, which are screwed into the U-shaped mounting plate 51 and threadedly engaged with the bending plate 52 to fix the position of the bending plate 52. The external threads of the multiple locking bolts 53 are connected to the inside of the bending plate 52. The U-shaped mounting plate 51 and the bending plate 52 are detachably fixed by a threaded connection. A pressure sensor 9 is provided on the outside of the bending plate 52. The pressure sensor 9 is used to detect the pressure of the bending plate 52 on the copper-clad laminate in real time and provide feedback pressure data for precise control of the bending process. The constraint component 6 includes a connecting plate 61. The connecting plate 61 is flat and is used to connect the base 1 and other components of the constraint component 6, serving as a load-bearing and transition function. Four fixing bolts 67 are threadedly connected to the top of the connecting plate 61. The four fixing bolts 67 securely install the connecting plate 61 on the top of the base 1. The external threads of the four fixing bolts 67 are connected to the top of the base 1. The connection between the connecting plate 61 and the base 1 is fixed by the threaded connection, ensuring that the constraint component 6 is installed securely. A support plate 62 is fixedly connected to the top of the connecting plate 61. The support plate 62 is a vertically arranged plate structure used to install components such as electric push rods 63 and provide support. Two electric push rods 63 are fixedly connected to the outside of the support plate 62. The electric push rods 63 are linear drive elements that can output linear drive force to drive the push plate 65 to move. The drive ends of the two electric push rods 63 are fixedly connected to the push plate 65. The push plate 65 is driven by the electric push rods 63 and can reciprocate in the horizontal direction, pushing the copper-clad laminate closer to the mold assembly 8 and applying constraint. The external fixed push plate 65 A rubber pad 66 is connected. The rubber pad 66 is made of flexible material, which can avoid hard damage when in contact with the copper-clad laminate, while increasing friction and improving the constraint effect. A limit plate 64 is fixedly connected to the top of the connecting plate 61. The limit plate 64 is a plate-shaped structure with through holes adapted to the electric push rods 63. It guides and limits the movement of the electric push rods 63. The inside of the limit plate 64 is slidably connected to the outside of the two electric push rods 63. The electric push rods 63 pass through the through holes of the limit plate 64. The limit plate 64 restricts the movement direction of the electric push rods 63, making them move stably in a straight line.
[0014] Working principle: Based on the specifications of the copper-clad laminate to be bent, the mold assembly 8 is adjusted to fit. By pushing the semi-cylinder 82 to slide on the top of the mold body 81, the relative positions of the two semi-cylinders 82 are initially determined by the cooperation of the adjusting column 84 and the compression spring 85 to form a support arc that meets the bending requirements of the copper-clad laminate. Then, the tightening bolt 83 is tightened, and the position of the semi-cylinder 82 is fixed by the clamping action of the tightening bolt 83. Then, by rotating the expansion positioning pin 87, the mold body 81 is securely locked in the preset groove 7 by its threaded connection with the inner side of the base 1 and the fixing block 86. The processing position provides precise and stable mold support for bending the copper clad laminate. For the copper clad laminate to be bent, the constraint component 6 is used for positioning constraint. The connecting plate 61 is assembled on the top of the base 1 by fixing bolts 67, so that the support plate 62, the limiting plate 64, etc. are in the working posture. The electric push rod 63 is activated to drive the push plate 65 to slide along the guide of the limiting plate 64. The flexible contact of the rubber pad 66 on the outside of the push plate 65 is used to apply the pushing force from both sides of the copper clad laminate, pushing the copper clad laminate and pressing it against the predetermined processing area above the mold component 8. At the same time, the horizontal displacement of the copper clad laminate during the bending process is restricted to ensure the accuracy of the bending position. After the workpiece is positioned, the hydraulic cylinder 3 is activated, and its drive end extends to drive the hydraulic rod 4 downward, bringing the bending assembly 5 close to the copper-clad laminate on the mold assembly 8. In the bending assembly, the U-shaped mounting plate 51 moves down synchronously with the hydraulic rod 4. If it is necessary to replace the bending plate 52 with one suitable for different bending requirements, the locking bolt 53 can be loosened, the original bending plate 52 can be removed and a new plate can be installed, and then the locking bolt 53 can be tightened to complete the fixation. When the bending plate 52 presses down to contact the copper-clad laminate, the pressure sensor 9 monitors the contact pressure in real time. When the pressure reaches the preset reasonable range, the hydraulic cylinder 3 precisely controls the stroke and pressure of the hydraulic rod 4, so that the bending plate 52 cooperates with the mold assembly 8. The semi-cylinder 82 applies bending force to the copper-clad laminate. Utilizing the curvature of the mold assembly and the downward pressure of the bending plate, the copper-clad laminate is bent to a predetermined angle. During the bending process, the pressure sensor 9 continuously collects pressure data. If the pressure exceeds a preset threshold, parameters such as the output pressure of the hydraulic cylinder 3 and the downward speed of the hydraulic rod 4 are adjusted. At the same time, the mold assembly 8, through structures such as the semi-cylinder 82 and the compression spring 85, can buffer and adapt to changes in bending force to a certain extent, and the constraint assembly 6 continuously maintains the horizontal limit on the copper-clad laminate. The collaboration of multiple components ensures a stable and precise bending process, completing the high-quality bending processing of the copper-clad laminate.
