Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of strip steel surface treatment technology, and more specifically, to a high surface quality hot-dip galvanized strip steel leveling machine. Background Technology

[0002] Steel rusts easily in air and water, while zinc's corrosion rate in the atmosphere is only 1 / 15 that of steel. Galvanized steel sheet uses a dense zinc coating to protect the steel sheet from corrosion. Steel strip refers to a conveyor belt made of carbon steel, used as a traction and carrying component of a belt conveyor, and can also be used to bundle goods. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Steel strip, also known as strip steel, has a width of less than 1300mm, and the length varies slightly depending on the size of each coil. Steel strip is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, easy processing, and material saving. Steel strip is divided into two categories according to the material used: ordinary steel strip and high-quality steel strip; and according to the processing method: hot-rolled steel strip and cold-rolled steel strip. Generally, steel strip requires special machines for leveling.

[0003] However, the existing hot-rolled strip precision leveling machine used for hot-dip galvanized steel strip processing cannot meet the requirements for steel strip leveling, cannot flatten steel strips of different thicknesses, increases the burden on workers, and cannot meet the requirements for precision leveling, thus failing to improve product quality.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0035] like Figures 1-4 As shown, it illustrates a high surface quality hot-dip galvanized strip leveling machine according to an embodiment of the present disclosure, comprising:

[0036] The frame 1 and a pair of conveyor rollers 2 are both disposed inside the frame 1;

[0037] The leveling roller 3 and the leveling component 5 are provided. The leveling roller 3 is rotatably connected inside the frame 1, and the leveling component 5 is disposed on the frame 1 and the leveling roller 3.

[0038] A pair of guide rollers 4, both of which are rotatably connected inside the frame 1;

[0039] Temperature processing component 6 is disposed inside the frame 1;

[0040] The leveling component 5 includes several hydraulic cylinders 5-1, which are respectively arranged on the inner and outer sides of the frame 1. The output end of the hydraulic cylinders 5-1 is connected to a top frame 5-2. Several flattening rollers 5-3 are rotatably connected between the top frames 5-2. The flattening rollers 5-3 are all located on the top of the leveling rollers 3. A cavity 5-4 is opened inside the leveling rollers 3. A fixing frame 5-5 is provided on the side surface of the frame 1. An inner frame 5-6 is provided on the side surface of the fixing frame 5-5. The inner frame 5-6 is located inside the cavity 5-4. Several internal heating tubes 5-7 are fixed on the inner frame 5-6.

[0041] In some examples, a flattening component 5 is designed to achieve the effect of flattening the strip surface. Two hydraulic cylinders 5-1 are set on both the inner and outer sides of the frame 1. The output end of the hydraulic cylinder 5-1 is connected to the top frame 5-2, which can control the lifting height of the top frame 5-2. Multiple flattening rollers 5-3 are rotatably connected between the top frames 5-2, which can control the flattening rollers 5-3 to cooperate with the leveling rollers 3 to flatten the strip. The flattening rollers 5-3 have a cavity 5-4 inside, and a fixed frame 5-5 is fixed on the outside. An inner frame 5-6 is set on the fixed frame 5-5. The inner frame 5-6 is located in the cavity 5-4. Multiple internal heating tubes 5-7 are fixed on the inner frame 5-6, which can pressurize the flattening rollers 5-3 and increase the flattening effect of the strip through heat.

[0042] like Figures 1-4 As shown, this embodiment proposes the temperature treatment component 6, which includes a pair of partitions 6-1, both of which are disposed inside the frame 1. Several surface heating tubes 6-2 are disposed inside each partition 6-1. Several support rollers 6-3 are rotatably connected inside the frame 1. Several pull-out rollers 6-4 are rotatably connected inside the frame 1. One end of each pull-out roller 6-4 is provided with a transmission gear 6-5. A drive shaft 6-6 is disposed on the outside of the frame 1. The drive shaft 6-6 is rotated by a motor. Several drive gears 6-7 are disposed on the drive shaft 6-6, and the drive gears 6-7 mesh with the transmission gears 6-5. A pair of top plates 6-8 are disposed inside the frame 1, and several fans 6-9 are disposed on the top plates 6-8.

[0043] In some examples, a temperature treatment component 6 is designed to achieve the effects of heating and cooling the strip. Inside the frame 1, there is a partition 6-1 and multiple surface heating tubes 6-2. The partition 6-1 is located at the entry end of the strip and can heat the surface of the strip to improve the flattening effect. At the other end, there are multiple support rollers 6-3 and a strip-out roller 6-4. One end of the strip-out roller 6-4 is equipped with a transmission gear 6-5. On the outside of the frame 1, there is a drive shaft 6-6 and multiple drive gears 6-7. The drive gears 6-7 mesh with the transmission gears 6-5 and can control the multiple strip-out rollers 6-4 to rotate synchronously. They cooperate with the support rollers 6-3 to convey the strip outward. Inside the frame 1, there are multiple top plates 6-8. Multiple fans 6-9 are installed on the top plates 6-8 to cool the flattened strip.

[0044] For example, such as Figure 1 As shown, exhaust ports 7 are provided on both sides of the frame 1, and the exhaust ports 7 are located below the top plate 6-8.

[0045] In some examples, an exhaust port 7 is provided to facilitate the rapid discharge of air blown downwards by fans 6-9, thereby improving the heat dissipation effect.

[0046] For example, such as Figure 3 As shown, several of the flattening rollers 5-3 are evenly distributed in an arc shape on the top of the flattening roller 3.

[0047] In some examples, configuring multiple flattening rollers 5-3 can improve the flattening effect on the strip and make the processing more uniform.

[0048] For example, such as Figure 2 As shown, both the drive gear 6-7 and the transmission gear 6-5 adopt a bevel gear structure.

[0049] In some examples, a 90° transmission angle can be achieved through bevel gears, which facilitates the simultaneous synchronous rotation of multiple pull-out rollers 6-4.

[0050] For example, such as Figure 3 As shown, the surface heating tubes 6-2 inside the pair of shrouds 6-1 face the two surfaces of the strip steel respectively.

[0051] In some examples, simultaneous heating on both sides can improve the heating effect and make the strip heat up more evenly.

[0052] When leveling is required, the strip enters at the conveyor roller 2, enters at the bottom of the leveling roller 3 and wraps upwards around the surface of the leveling roller 3. Then, it is clamped by the pull-out roller 6-4 and the support roller 6-3, and the pull-out roller 6-4 is started to convey it outwards. According to the thickness of the strip, the hydraulic cylinder 5-1 is started to control the top frame 5-2 to descend, pressing multiple flattening rollers 5-3 onto the surface of the strip, which works with the leveling roller 3 to flatten it. At the same time, the internal heating pipe 5-7 and the surface heating pipe 6-2 are started to raise the temperature of the strip, which can improve the flattening effect. After the strip is leveled, the fan 6-9 is started to blow air to cool it down.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
