Description

Technical Field

[0001] The present invention relates to the technical field of cold-rolled steel plate processing, and particularly relates to a continuous production device for cold-rolled steel plates. Background Art

[0002] Cold-rolled steel plates refer to steel plates obtained by rolling hot-rolled steel plate billets below the recrystallization temperature. Usually, through multiple passes of rolling, the thickness of the steel plate is reduced, the dimensional accuracy is improved, the surface quality is improved, and specific mechanical properties are imparted. The production process of cold-rolled steel plates is as follows: First, a suitable hot-rolled steel plate is selected as the billet, and the billet needs to undergo surface pretreatment, such as removing impurities such as scale and oil stains, to ensure the smooth progress of the rolling process. The pretreated billet enters the cold rolling mill, and under the strong pressure of the rolling rolls, the steel plate undergoes plastic deformation and the thickness gradually decreases. During the rolling process, parameters such as the gap between the rolling rolls, the rolling speed, and the tension need to be precisely controlled to ensure that the thickness, shape, and performance of the steel plate meet the requirements. However, traditional cold-rolled steel plate production is often intermittent, with较多工序衔接等待时间,such as the billet replacement, the equipment restart after adjusting the rolling parameters, etc., resulting in low overall production efficiency.

[0003] In the prior art, a Chinese invention patent document with the publication number CN118180761A was proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: The invention relates to the field of cold-rolled steel plate processing, and particularly relates to a continuous production device for cold-rolled steel plates and cold-rolled steel plates. The device includes a first frame, a second frame, a cold-rolled steel plate coil placement table, an uncoiling wheel, an auxiliary wheel, and a traction wheel. A welding platform is slidably installed between the auxiliary wheel and the traction wheel of the second frame. The welding platform is provided with a first bottom plate, a second bottom plate, a pressing plate, an avoidance opening, a movable plate, a first welding head, and a second welding head. The first welding head and the second welding head are fixedly installed on a "C"-shaped connecting frame. The connecting frame is connected to a connecting block at the bottom of the movable plate. A vertical limiting insertion rod is provided at the bottom of the connecting block, and the limiting insertion rod is inserted into a limiting sliding groove provided at the bottom of the second frame. This technical solution synchronously welds the upper and lower sides of new and old cold-rolled steel plates, and the welding process is automatically carried out during movement, improving the working efficiency and the strength of the welding joint at the same time.

[0004] It can be seen from the technical solution proposed in the above-mentioned invention patent document that the above-mentioned solution still has obvious shortcomings. For example, when two cold-rolled steel plates are welded by the welding platform in the above-mentioned technical solution, the ends of the two cold-rolled steel plates need to be kept in contact with each other and highly flush before welding. However, after the steel plates have undergone multiple rounds of rolling, the thickness of the steel plates changes, and the ends of the steel plates produce uncontrollable deformation and stretching during the rolling process, making it impossible to weld the two steel plates with different thicknesses and end faces that cannot be fitted together. Even if the welding is completed, the welding point is too thin, resulting in a weak weld between the two steel plates, which in turn affects the subsequent operation of the cold-rolled steel plates. Therefore, the prior art urgently needs a technical solution to solve the above-mentioned problems. Summary of the invention

[0021] As a further illustration of the embodiment of the present invention, when welding two cold-rolled steel plates in the prior art, the ends of the two cold-rolled steel plates need to be kept in a state of being in close contact with each other and highly flush before welding can be performed. However, after the steel plates have been rolled for multiple rounds, the thickness of the steel plates changes, and the ends of the steel plates undergo uncontrollable deformation and stretching during the rolling process, making it impossible to weld two steel plates with different thicknesses and end faces that cannot be in close contact. Even if the welding is completed, the welding point is too thin, resulting in the welding between the two steel plates not being firm, thereby affecting the subsequent operation of the cold-rolled steel plates. In this embodiment, the second transmission assembly 3 is driven by the driving assembly 6 to slide axially along the support rod 11, and the spacing between the first transmission assembly 2 and the second transmission assembly 3 is adjusted according to the thickness of the steel plate, and the steel plate is rolled and transmitted backward through the cold rolling equipment externally connected to the ends of the first transmission assembly 2 and the second transmission assembly 3. When manual or electronic equipment detects that the steel plates need to be welded, the ends of the steel plates in the first conveying assembly 2 and the second conveying assembly 3 are conveyed to the top support assembly 4 (hereinafter referred to as the initial steel plate for easy distinction), the initial steel plate is fixed by the top support assembly 4 and the bearing plate 41, the cutting assembly 5 is started to cut the ends of the initial steel plates, and after cutting, the new steel plates are rolled and fed in from the ends of the first conveying assembly 2 and the second conveying assembly 3 (hereinafter referred to as the subsequent steel plates), the subsequent steel plates are conveyed to the top support assembly 4 by the first conveying assembly 2 and the second conveying assembly 3, the subsequent steel plates are fixed by the top support assembly 4, the cutting assembly 5 is started to cut the ends of the subsequent steel plates, and after cutting, the waste 10 is pushed away from the bearing plate 41 by the telescopic push plate (for details, refer to Figure 5), and then the first conveying assembly 2 and the second conveying assembly 3 cooperate with the adjustment of the supporting assembly 4 to align and fit the ends of the initial steel plate and the subsequent steel plate at the preset points, and start the first welding assembly 7 and the second welding assembly 8 to perform double-sided welding operations on the ends of the initial steel plate and the subsequent steel plate, so that the two steel plates are fixedly connected into a whole. The present invention rolls and conveys the steel plates through the first conveying assembly 2 and the second conveying assembly 3, ensuring that the thickness of the two steel plates is the same, and then the ends of the steel plates after rolling and deformation are cut off by the cutting assembly 5, thereby ensuring that the ends of the two steel plates can fit each other before welding, thereby improving the stability of the welding operation of the two steel plates, and further improving the firmness of the two steel plates after welding.

[0023] As a further illustration of an embodiment of the present invention, the cutting assembly 5 in this embodiment adjusts the horizontal height of the mounting base 57 through the hydraulic box 56, so that the saw blade 58 can be close to or away from the steel plate fixed by the support assembly 4, and the saw blade 58 is driven by the driving motor to rotate at high speed, so that the high-speed rotating saw blade 58 rubs against the steel plate to achieve the purpose of cutting the steel plate, and then the first driving motor 53 drives the lead screw 52 to rotate, thereby driving the saw blade 58 to slide back and forth along the axial direction of the lead screw 52, ​​so that the saw blade 58 has the effect of transversely cutting the steel plate.

[0024] As a further description of an embodiment of the continuous production equipment for cold-rolled steel plates, the first conveying component 2 includes a first mounting frame 21 fixedly connected to the tops of a plurality of support rods 11, a plurality of first transmission rollers 22 are rotatably mounted in the first mounting frame 21, an extension plate 23 is fixedly mounted on the bottom of the first mounting frame 21, a synchronization component 9 for driving the plurality of first transmission rollers 22 to rotate is fixedly mounted on the side wall of the extension plate 23, and the second conveying component 3 has the same structure as the first conveying component 2, and the second conveying component 3 includes a second mounting frame 31 and a second transmission roller 32.

[0026] As a further explanation of the embodiment of the present invention, the rolling and conveying principle of the first conveying component 2 and the second conveying component 3 in the present embodiment is as follows: a plurality of first transmission rollers 22 are driven to rotate in the first mounting frame 21 by the synchronization component 9, the rotation directions of the first transmission rollers 22 and the second transmission rollers 32 are opposite, and the first transmission rollers 22 correspond to the second transmission rollers 32 one by one, when the steel plate enters from one end of the first mounting frame 21 and passes through the gap between the first transmission roller 22 and the second transmission roller 32 at the end, the steel plate whose thickness exceeds the gap between the first transmission roller 22 and the second transmission roller 32 is deformed when subjected to the rotational extrusion force of the first transmission roller 22 and the second transmission roller 32, and the deformed steel plate is conveyed forward by the rolling friction force of the first transmission roller 22 and the second transmission roller 32, and enters the gap formed between the next group of first transmission rollers 22 and the second transmission roller 32, thereby achieving the effect of conveying and repeatedly rolling the steel plate.

[0027] The synchronous assembly 9 in this embodiment forms a whole with multiple synchronous wheels 92 through a synchronous belt 97. When any synchronous wheel 92 rotates, it can drive other synchronous wheels 92 to rotate in the same direction. The tensioning wheel 95 is used to adjust the slackness of the synchronous belt 97 to facilitate the installation or removal of the synchronous belt 97.

The supporting assembly 4 in this embodiment supports the supporting plate 44 downward through the output end of the cylinder 43, so that the supporting plate 44 presses down against the steel plate, and presses the steel plate against the bearing plate 41, so that the steel plate cannot be transported forward by the first transmission roller 22 and the second transmission roller 32, thereby achieving the effect of fixing the steel plate. As a further preferred solution of the present embodiment, the lower surface of the push plate 44 is made of a rough material having greater friction with the surface of the steel plate, so that the friction between the push plate 44 and the steel plate is increased, further improving the fixing effect of the push plate 44, and the downward fixing supporting force of the push plate 44 is controlled within a certain range to avoid deformation of the steel plate due to excessive downward supporting force of the push plate 44.
