Description

High-quality cold-rolled strip steel has wide applications in industries such as automobiles, shipbuilding, bridges, construction, aerospace, instrumentation, electronics, food packaging, and home appliances. Its quality and performance directly affect the competitiveness of downstream products. In particular, with the development of the automotive industry, high-end automotive panels place increasingly higher demands on cold-rolled strip steel, requiring not only high strength and toughness but also lightweight and corrosion resistance.

[0003] However, some cold-rolled strip forming equipment has a relatively simple structure and still uses manual operation to adjust the gap between the rolls to ensure appropriate rolling force and product thickness. Since a small amount of internal stress is generated during the cold rolling process, problems such as strip warping and wavy may occur. Manually adjusting the gap between the rolls may cause the strip to lose the force of the rolls, warp up, and scratch personnel or damage the equipment. Utility Model Content

[0014] 1. By setting up a pressing and rolling mechanism, the prismatic geometry principle of the prismatic hinge frame is utilized, so that the hydraulic cylinder drives the upper receiving block to press down, which in turn drives the lower receiving block to rise.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 As shown, this utility model provides a technical solution: a high-precision automated forming equipment for cold-rolled strip steel, including a first outer shell 1, on which a rolling mechanism 2 and an elongation mechanism 3 are arranged.

[0025] The pressing mechanism 2 includes a pressing assembly and a driving assembly. The pressing assembly includes two second housings 21 fixedly connected to the left and right sides of the first housing 1. The inner walls of the two second housings 21 each have two first grooves 22. The inner walls of the first grooves 22 each have several connecting grooves 23. The inner walls of the connecting grooves 23 on the left and right sides are slidably connected to limit blocks 24. The inner walls of the connecting grooves 23 on the upper and lower sides are slidably connected to first connecting rods 25. The ends of the first connecting rods 25 and the limit blocks 24 that are far apart from each other extend to the inner wall of the first grooves 22.

[0026] Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly includes a prismatic hinge frame 26 that is hinged to the outer walls of several first connecting rods 25 and limiting blocks 24. Two hydraulic cylinders 27 are fixedly connected to the top surfaces of the two second housings 21. Two receiving blocks 28 are slidably connected to the inner walls of several first grooves 22. The top surfaces of several receiving blocks 28 located on the upper side are fixedly connected to the output ends of the hydraulic cylinders 27. Springs 29 are fixedly connected to the sides of several receiving blocks 28 that are close to each other. Pressure rollers 210 are rotatably connected to the outer walls of several first connecting rods 25.

[0027] By setting up the rolling mechanism 2, the prismatic geometry of the prismatic hinge frame 26 is utilized, so that the hydraulic cylinder 27 drives the upper receiving block 28 to press down, which in turn drives the lower receiving block 28 to rise. The compression spring 29 acts as a buffer, while the first connecting rod 25 drives the two rolling rollers 210 to move closer to each other, rolling and flattening the strip steel. In conjunction with the extension mechanism 3 and several mechanical structures, the cold-rolled strip steel is automatically driven, reducing manpower input and safety risks, ensuring the stable operation of the device, and improving the practicality of the device.

[0028] Among them, such as Figure 2 , Figure 3 and Figure 5As shown, the extension mechanism 3 includes a flipping assembly, a linkage assembly, and a cooling assembly. The flipping assembly includes two second grooves 31 formed on the inner wall of the first outer shell 1. Each of the two second grooves 31 has several arc-shaped grooves 32 on its inner wall. Each arc-shaped groove 32 has a second connecting rod 33 slidably connected to its inner wall. The ends of the second connecting rods 33 that are far apart from each other extend to the inner wall of the second groove 31. Each second connecting rod 33 has a sleeve 38 rotatably connected to its outer wall. The linkage assembly includes several connecting blocks 34 rotatably connected to the inner walls of the two second grooves 31. The inner walls of the two grooves 31 are rotatably connected to the rotating shafts 35. The outer walls of the rotating shafts 35 are fixedly connected to the inner walls of the connecting block 34. The outer walls of the rotating shafts 35 are fixedly connected to the gears 36. Two chains 37 are sleeved between the gears 36. The front of the first housing 1 is fixedly connected to the motor 39. The output end of the motor 39 is fixedly connected to the front end of the rotating shaft 35 located on the front right side through a coupling. The cooling assembly includes a fan cooler 310 fixedly connected to the inner wall of the first housing 1. The ends of the second connecting rods 33 that are far apart from each other are rotatably connected to the inner walls of the connecting block 34.

[0029] By setting up the extension mechanism 3, the motor 39 drives the chain 37 and several gears 36 to rotate several connecting blocks 34 around the rotating shaft 35. This causes the connecting blocks 34 to drive the sleeve 38 to flip along the arc groove 32 through the second connecting rod 33, bending the strip steel after being pressed by the rolling mechanism 2, diffusing the internal stress of the strip steel and avoiding wrinkles, thus further improving the practicality of the device.

[0030] When used in high-precision cold-rolled strip automated forming equipment, the air-cooled unit 310 is typically used in air conditioning, refrigerators, computer cooling, and other fields. The air-cooled unit compresses the refrigerant into a high-temperature, high-pressure gas through a compressor or other equipment, and then sends it into the condenser. Through the pipes and fins of the condenser, the surface of the condenser dissipates the heat in the gas into the surrounding air through contact with the air. The high-temperature gas in the condenser gradually cools down into a room-temperature liquid. The condensed liquid refrigerant then passes through a throttling device to reduce its pressure. The throttling process lowers the temperature of the liquid refrigerant, and the low-temperature, low-pressure liquid refrigerant enters the evaporator. During this process, the refrigerant absorbs heat from the surrounding air and quickly evaporates into gas. The evaporator usually has fins or a radiator surface to maximize the heat absorption of the refrigerant when it comes into contact with the air. After absorbing heat in the evaporator, the refrigerant becomes a low-temperature gas and returns to the compressor for recompression, forming a closed-loop refrigeration cycle. The continuous circulation of the refrigerant absorbs heat and dissipates it into the ambient air, achieving a continuous cooling or temperature reduction effect.

[0031] By setting up the pressing mechanism 2, the strip steel passes through the two pressing rollers 210 and several sleeves 38 on one side via the winding device. At this time, several hydraulic cylinders 27 drive several upper receiving blocks 28 to slide downward in the connecting groove 23. According to the prismatic geometry principle of the prismatic hinge frame 26, when the upper first connecting rod 25 drives the upper end of the prismatic hinge frame 26 to slide towards the center, the limiting action of the two limiting blocks 24 on the left and right sides drives the first connecting rod 25 hinged at the lower end of the prismatic hinge frame 26 to slide upward, so that the two pressing rollers 210 move closer to each other, while the two limiting blocks 24 move away from each other in the connecting groove 23. The two pressing rollers 210 approach each other and contact the strip steel. The hydraulic cylinders 27 continue to drive, driving the two pressing rollers 210 to simultaneously squeeze the strip steel towards the center, reducing its thickness and slightly lengthening the strip steel. With the help of the extension mechanism 3, the strip steel is flipped and bent to diffuse the internal stress of the strip steel and avoid small wrinkles. After that, the strip steel... The strip steel, bent by the extension mechanism 3, is flattened by the pressure of two pressure rollers 210 on the other side. Simultaneously, the lower first connecting rod 25 drives the lower receiving block 28 to slide upward, causing the two receiving blocks 28 to move closer to each other and compress the spring 29. The spring 29 acts as a buffer to prevent the hydraulic cylinder 27 from applying excessive force, which could damage the strip steel or other components. This utilizes the prismatic geometry of the prismatic hinge frame 26, allowing the hydraulic cylinder 27 to drive the upper receiving block 28 downward, which in turn drives the lower receiving block 28 upward. While the compression spring 29 acts as a buffer, the first connecting rod 25 drives the two pressure rollers 210 to move closer to each other, flattening the strip steel. In conjunction with the extension mechanism 3 and several mechanical structures, the cold-rolled strip steel is automatically driven, reducing manpower input and safety risks, ensuring stable operation of the device, and improving its practicality.

[0032] After the extension mechanism 3 is set up and the rolling mechanism 2 on one side completes the rolling process, the drive motor 39 drives the front right rotating shaft 35 to rotate. This causes the front right gear 36 to drive several gears 36 to rotate through the linkage of the chain 37. The gears 36 drive the rotating shaft 35 to rotate. The rotation of the rotating shaft 35 drives the connecting block 34 to rotate. The second connecting rods 33 rotatably connected to both ends of the connecting block 34 cause the rotating shaft 35 to slide and rotate along the limiting guide of the arc groove 32. This causes the sleeve 38 to rotate around the rotating shaft 35, thus creating a wave-like motion in the strip between the rotating shafts 35. The strip rolled on one side of the rolling mill 2 is bent and extended to disperse the internal stress of the strip and prevent wrinkles. At the same time, the air cooler 310 is driven to generate air cooling to remove the heat from the surface of the strip, thus completing the cold rolling process. The device is driven by a motor 39, which drives a chain 37 and several gears 36 to rotate several connecting blocks 34 around the rotating shaft 35. The connecting blocks 34 drive the sleeve 38 to rotate along the arc groove 32 through the second connecting rod 33, thus bending the strip rolled by the rolling mill 2, dispersing the internal stress of the strip and preventing wrinkles, which further improves the practicality of the device.
