Limiting mechanisms are installed at both ends of the forming device and the leveling mechanism. A cutting mechanism is installed on the left side of the leveling mechanism, and a conveying mechanism is installed on the left side of the cutting mechanism. After the steel plate is released by the uncoiling machine, it is supported and guided by the support rollers and guide rollers. The forming device pulls the material in and processes the steel plate into shape. The leveling mechanism can adjust the processed heat sink to ensure flatness. The cutting mechanism can cut the heat sink. The conveying mechanism outputs the cut heat sink. The limiting mechanism can limit and guide the steel plate during conveying, and can be adjusted according to the width of the steel plate to ensure processing accuracy. Integrated processing saves time and labor, and occupies less space.

[0005] Preferably, the forming device includes two pulling rollers, two sets of adjusting seats, two sets of hydraulic cylinders, two sets of die rollers, multiple telescopic drive shafts, and two limiting plates. Multiple adjusting slots are provided at the bottom of the frame. The hydraulic cylinders are installed at the bottom of the adjusting slots, and the adjusting seats are slidably installed at the bottom of the adjusting slots. The telescopic ends of the hydraulic cylinders are connected to the adjusting seats. Pulling rollers are rotatably installed at the front and rear ends of the right side of the frame and between the front and rear adjusting seats. Multiple sets of die rollers are rotatably installed on the left side of the pulling rollers. Telescopic drive shafts are installed at the input ends of the pulling rollers and die rollers, and limiting plates are installed between the pulling rollers and die rollers. The telescopic drive shafts are connected to an external drive device. The telescopic drive shafts drive the pulling rollers to rotate and pull in the material. At the same time, the telescopic drive shafts drive the multiple sets of die rollers to rotate and form the steel sheet. The hydraulic cylinders push the adjusting seats to move, adjusting the distance between the upper and lower die rollers. The rollers can be pushed up and down according to the thickness of the steel sheet to ensure contact between the die rollers and the steel sheet, ensuring processing quality.

[0006] Preferably, the leveling mechanism includes two crossbeams, two adjusting plates, two sets of adjusting screws, two sets of adjusting nuts, and two sets of leveling rollers. The two crossbeams are installed at the front and rear ends of the left side wall of the machine frame. Leveling rollers are rotatably installed on the lower part of the two crossbeams, and a sliding groove is opened inside. The adjusting screws are installed on the top of the crossbeams, and the adjusting nuts are screwed onto the adjusting screws. The adjusting plates are located in the sliding grooves, and the top of the adjusting plates is connected to the bottom of the adjusting screws. Leveling rollers are rotatably installed between the front and rear adjusting plates and corresponding to the lower leveling rollers. After the steel plate is processed and formed, it passes between the upper and lower sets of leveling rollers to adjust and level it, ensuring the straightness of the heat sink and improving the processing quality. The adjusting nuts and adjusting screws can move the adjusting plates in the sliding grooves to adjust the distance between the upper and lower sets of leveling rollers, which can be adjusted according to the thickness of the steel plate.

[0007] Preferably, the cutting mechanism includes a base, support legs, multiple columns, a top plate, a first hydraulic cylinder, two connecting seats, two vertical rods, and two springs.

Vertical rods are installed on the top of the connecting seats. The upper die is slidably installed at both ends of the upper die. Two springs are fitted on the outer wall of the vertical rods. When the first hydraulic cylinder is activated, it pushes the upper cutting die downward to cut the formed heat sink according to the required length. When the upper die moves downward, it slides on the vertical rods and compresses the springs to store energy.

[0008] Preferably, the limiting mechanism includes a rotating rod, an adjusting handle, two movable seats, two supporting slide rods, and two sets of limiting rollers. The rotating rod has symmetrically threaded grooves at both ends. The rotating rod is rotatably mounted on the right end of the frame and the left end of the crossbeam.

The movable seats are screwed onto the outer wall of the rotating rod in the middle. The left and right ends of the movable seats are slidably mounted on the outer walls of the supporting slide rods. Limiting rollers are rotatably installed at the top left and right ends of the movable seats. The steel plate material passes between the two sets of limiting rollers, which limit and guide the material, preventing it from shifting and affecting processing accuracy. The adjusting handle drives the rotating rod to rotate, causing the movable seats to slide on the supporting slide rods, thereby adjusting the distance between the limiting rollers. This distance can be adjusted according to the width of the material.

[0009] Preferably, the conveying mechanism includes a base frame, two transmission boxes, two sets of conveying rollers, a fixed frame, two first screws, two support arms, a rotating roller, and a pressure roller.

[0020] After the steel plate is released by the uncoiling machine, it is supported and guided by the support roller 2 and the guide roller 3. The telescopic drive shaft 8 is connected to the external drive device. The telescopic drive shaft 8 drives the pulling roller 4 to rotate and pull the material in. At the same time, the telescopic drive shaft 8 drives multiple sets of mold rollers 7 to rotate and process the steel plate into shape. The hydraulic cylinder 6 pushes the adjusting seat 5 to move, which can adjust the distance between the upper and lower mold rollers 7. It can push up and down according to the thickness of the steel plate to ensure contact between the mold rollers 7 and the steel plate and ensure processing quality. After processing, the steel plate passes between the upper and lower sets of leveling rollers 22 to adjust and flatten the steel plate, ensuring the straightness of the heat sink and improving processing quality. The adjusting nut 21 and adjusting screw 20 can move the adjusting plate 19 in the slide groove to adjust the distance between the upper and lower sets of leveling rollers 22 according to the thickness of the steel plate. The first hydraulic cylinder 27 is started to push the cutting upper die downward to cut the formed heat sink according to the required length. When the upper die moves downward, it slides on the vertical rod 29, while compressing the spring 30 to store energy. The steel plate passes between the front and rear sets of limiting rollers 17, which limit and guide the plate material to prevent it from shifting and affecting the processing accuracy. By adjusting the lever 14, the rotating rod 13 is driven to rotate, so that the moving seat 15 slides on the support slide rod 16, thereby adjusting the distance between the limiting rollers 17. This distance can be adjusted according to the width of the material. The starting motor drives the multiple conveying rollers 33 to rotate through the transmission box 32. The cut heat sink is conveyed onto the multiple conveying rollers 33.

The steel plate passes under the encoder 12, which can count the meters accurately as needed, and then facilitates subsequent cutting and pressing. The position of the encoder 12 can be adjusted by the electric telescopic rod 11 for easy adjustment.

[0021] like Figures 1 to 5As shown, in operation, the heat sink forming machine of this utility model releases the steel plate through the uncoiling machine. The support roller 2 and guide roller 3 support and guide the steel plate. The machine is connected to an external drive device. The telescopic transmission shaft 8 drives the pulling roller 4 to rotate and pull in the material. Simultaneously, the telescopic transmission shaft 8 drives multiple sets of mold rollers 7 to rotate and process the steel plate into shape. The hydraulic cylinder 6 pushes the adjusting seat 5 to move, adjusting the distance between the upper and lower mold rollers 7. The distance can be adjusted according to the thickness of the steel plate, ensuring contact between the mold rollers 7 and the steel plate. After processing, the steel plate passes between the upper and lower sets of leveling rollers 22 to adjust and level it, ensuring the straightness of the heat sink. This is achieved by adjusting the nut 21 and the adjusting screw 2. The 0 mechanism allows the adjusting plate 19 to move within the chute, adjusting the distance between the upper and lower sets of leveling rollers 22. This distance can be adjusted according to the thickness of the steel plate. The steel plate passes between the front and rear sets of limiting rollers 17, which limit and guide the plate material to prevent it from shifting. The steel plate passes under the encoder 12, where it can be counted. Based on the precise meter reading, the first hydraulic cylinder 27 is activated to push the upper cutting die downwards, cutting the formed heat sink according to the required meter reading. The motor is started to rotate multiple conveying rollers 33 via the transmission box 32, and the cut heat sink is conveyed onto the multiple conveying rollers 33. The heat sink passes under the pressure roller 38, which positions it.

[0022] The encoder 12 and transmission box 32 of the heat sink forming machine of this utility model are purchased from the market.
