Description

Technical Field

[0001] This utility model relates to the field of C-shaped steel processing technology, and more specifically, to a cold rolling and shaping device for C-shaped steel processing. Background Technology

[0002] The C-shaped steel cold rolling forming device is a professional cold bending forming equipment used to produce C-shaped steel. This device uses a multi-pass continuous cold rolling forming process to gradually bend metal coils into structural profiles with a C-shaped cross-section at room temperature. For example, the C-shaped steel cold rolling forming machine proposed in publication number "CN219965979U" includes a base, with a hydraulic pushing and cutting mechanism on the top of the base. The hydraulic pushing and cutting mechanism includes a fixed plate, a C-shaped opening on one side of the fixed plate, multiple hydraulic rods fixed to one side of the fixed plate, and a cutting plate fixed to one side of each hydraulic rod. This utility model utilizes a hydraulic pushing and cutting mechanism;

[0003] However, the aforementioned C-shaped steel cold rolling forming machine lacks a structure for effectively cooling the pressure rollers responsible for forming the steel sheet. As a result, during the continuous cold bending forming process, the pressure roller assembly generates a large amount of heat due to high-speed friction with the metal strip, which is difficult to dissipate quickly. This not only exacerbates the wear of the pressure rollers, shortens their service life, and reduces forming accuracy, but may also affect the mechanical properties and surface quality of the strip due to heat accumulation. Utility Model Content

[0004] The main objective of this invention is to provide a cold rolling forming device for C-shaped steel processing. This device effectively addresses the lack of a structure in the prior art for effectively cooling the pressure rollers responsible for forming the steel sheet in C-shaped steel cold rolling forming machines. This results in a large amount of heat generated by the pressure roller assembly during continuous cold bending forming due to high-speed friction with the metal strip, which is difficult to dissipate quickly. This not only exacerbates the wear of the pressure rollers, shortens their service life, and reduces forming accuracy, but may also affect the mechanical properties and surface quality of the strip due to heat accumulation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cold rolling forming device for processing C-shaped steel includes a frame, a set of conveying rollers arranged between the two sides of the inner wall of the frame, and a set of pressure rollers arranged between the two sides of the inner wall of the frame.

[0007] A cooling assembly for cooling the pressure roller assembly is provided between the two sides of the inner wall of the frame.

[0008] The cooling assembly includes a bidirectional threaded rod, which is rotatably mounted between the two sides of the inner wall of the frame. A positioning rod is fixedly installed between the two sides of the inner wall of the frame. A movable frame is threaded on both sides of the bidirectional threaded rod, and the two movable frames are slidably mounted on both sides of the positioning rod.

[0009] The movable frame has an internal cavity, and the inner wall of the movable frame is provided with a number of nozzles, each of which is connected to a corresponding cavity.

[0010] A motor is fixedly mounted on one side of the frame via a positioning bracket, and one end of the bidirectional threaded rod passes through the frame and is fixedly connected to the motor output shaft.

[0011] Preferably, both of the outer walls of the movable frames are provided with water inlet pipes, and the interiors of the two water inlet pipes are respectively connected to the corresponding cavities.

[0012] Water pumps are installed on both sides of the frame, and the output ends of the two water pumps are fixedly connected to the corresponding water inlet pipes through corrugated pipes.

[0013] Preferably, a top plate is fixedly installed on the upper surface of the frame, a cylinder is fixedly installed on one side of the top plate, the output end of the cylinder passes through the top plate and is fixedly installed on a support frame, and two scrapers are fixedly installed on one side of the support frame.

[0014] Preferably, two limiting rods are slidably disposed on one side of the top plate, and both limiting rods are fixedly connected to the support frame.

[0015] Preferably, a water trough is provided on the bottom surface of the frame.

[0016] Preferably, inclined grooves are formed on both sides of the inner wall of the water tank.

[0017] Preferably, a triangular plate is fixedly installed at the bottom of the water tank.

[0018] Preferably, a filter plate is slidably disposed through one side of the frame, and a positioning plate is fixedly installed on one side of the filter plate, the positioning plate being fixedly connected to the frame by bolts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Start the motor. The motor drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the two moving frames and the moving frames are simultaneously slidably set on the positioning rod, the rotational motion is converted into the linear motion of the two moving frames in opposite directions along the axial direction of the positioning rod. This adjusts the two moving frames to the optimal cooling position covering the working area of ​​the pressure roller group. After the cooling position is adjusted, start the water pump. The water pump pumps the cooling medium through the bellows to the water inlet pipe. The cooling medium enters the cavity inside the moving frame through the water inlet pipe and is evenly distributed to each nozzle. The nozzles spray the cooling medium in the form of atomization or jet onto the roller surface and key areas of the working pressure roller group below. The cooling medium absorbs the frictional heat and flows away, achieving continuous, uniform and direct cooling of the pressure roller group, effectively suppressing the temperature rise of the pressure roller in the pressure roller group.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1-5 As shown, a cold rolling forming device for C-shaped steel processing includes a frame 1, a conveying roller group 2 arranged between the two sides of the inner wall of the frame 1, and a pressure roller group 3 arranged between the two sides of the inner wall of the frame 1.

[0029] A cooling assembly 4 for cooling the pressure roller group 3 is provided between the two sides of the inner wall of the frame 1;

[0030] Cooling assembly 4 includes a bidirectional threaded rod 401, which is rotatably mounted between the two sides of the inner wall of the frame 1. A positioning rod 402 is fixedly mounted between the two sides of the inner wall of the frame 1. A movable frame 403 is threaded on both sides of the bidirectional threaded rod 401, and the two movable frames 403 are slidably mounted on both sides of the positioning rod 402.

[0031] The movable frame 403 has an internal cavity, and the inner wall of the movable frame 403 is provided with a number of nozzles 404, each nozzle 404 being connected to the corresponding cavity.

[0032] A motor 406 is fixedly mounted on one side of the frame 1 via a positioning bracket 405. One end of a bidirectional threaded rod 401 passes through the frame 1 and is fixedly connected to the output shaft end of the motor 406.

[0033] Both movable frames 403 have water inlet pipes 5 on their outer walls, and the interiors of the two water inlet pipes 5 are connected to the corresponding cavities.

[0034] Water pumps 6 are installed on both sides of the frame 1, and the output ends of the two water pumps 6 are fixedly connected to the corresponding water inlet pipes 5 through corrugated pipes 7.

[0035] The frame 1 forms the main support structure of the device. The metal strip is first guided and conveyed by the conveyor roller group 2 to ensure its smooth entry into the forming station. The metal strip then enters the cold bending forming area composed of the pressure roller group 3. The pressure roller group 3 consists of multiple pairs of horizontally arranged forming rollers. Through its specific roller profile, it applies a continuous lateral bending force to the moving strip, causing its cross-sectional shape to gradually undergo plastic deformation, ultimately forming a C-shaped steel of the preset specifications. During continuous production, in order to overcome the heat problem generated by the high-speed friction of the pressure roller group 3, the cooling component 4 is activated. First, the motor 406 is started, and the motor 406 drives the bidirectional threaded rod 401 to rotate. Since the bidirectional threaded rod 401 is threadedly connected to two moving frames 403, and the moving frames 403 slide simultaneously... The rotational motion is converted into linear motion of two moving frames 403 along the axial direction of the positioning rod 402 in opposite directions. This adjusts the two moving frames 403 to the optimal cooling position covering the working area of ​​the pressure roller group 3. After the cooling position is adjusted, the water pump 6 is started. The water pump 6 pumps the cooling medium through the bellows 7 to the water inlet pipe 5. The cooling medium enters the cavity inside the moving frame 403 through the water inlet pipe 5 and is evenly distributed to each nozzle 404. The nozzle 404 sprays the cooling medium in the form of atomization or jet onto the roller surface and key areas of the working pressure roller group 3 below. After absorbing the frictional heat, the cooling medium flows away, achieving continuous, uniform and direct cooling of the pressure roller group 3, effectively suppressing the temperature rise of the pressure rollers in the pressure roller group 3.

[0036] In another embodiment of the present invention, a top plate 701 is fixedly installed on the upper surface of the frame 1, a cylinder 702 is fixedly installed on one side of the top plate 701, the output end of the cylinder 702 passes through the top plate 701 and is fixedly installed on a support frame 8, and two scrapers 9 are fixedly installed on one side of the support frame 8.

[0037] Two limiting rods 10 are slidably installed on one side of the top plate 701, and both limiting rods 10 are fixedly connected to the support frame 8.

[0038] After cooling, the medium used in the cooling process will remain on the surface of the pressure roller assembly 3. The cylinder 702 is activated, and the output end of the cylinder 702 drives the support frame 8 to move downward. The support frame 8 is fixedly connected to two limit rods 10. The limit rods 10 pass through and slide in the top plate 701. This structure ensures the vertical linear movement of the support frame 8. When the support frame 8 moves downward, it drives the two scrapers 9 fixed on one side to move downward synchronously until the working edge of the scraper 9 contacts the roller surface of the pressure roller assembly 3. During the continuous rotation of the pressure roller assembly 3, the scraper 9 in close contact with the roller surface scrapes off the liquid medium remaining on the roller surface, allowing the liquid to be guided away along the roller surface, avoiding water stains or rust hazards.

[0039] In another embodiment of this utility model, a water tank 11 is provided on the bottom surface of the inner side of the frame 1.

[0040] Inclined grooves 12 are provided on both sides of the inner wall of the water tank 11.

[0041] A triangular plate 13 is fixedly installed at the bottom of the water tank 11.

[0042] A filter plate 14 is slidably mounted through one side of the frame 1, and a positioning plate 15 is fixedly installed on one side of the filter plate 14. The positioning plate 15 is fixedly connected to the frame 1 by bolts 16.

[0043] During the operation of the cooling component 4, the cooling medium sprayed by the nozzle 404 cools the pressure roller assembly 3. The water, along with the impurities washed off, drips downwards. The dripping water and impurities are collected in a water tank 11 located on the bottom surface of the inner wall of the frame 1. The collected water containing impurities gathers in the water tank 11. Larger solid impurities in the water first settle to the bottom of the water tank 11 under gravity. The water continues to flow along the water tank 11. When it flows past the triangular plate 13 fixedly installed at the bottom of the water tank 11, the water is smoothly guided by the guiding effect of its cross-sectional shape. Subsequently, the water flows through the inclined grooves on both sides of the inner wall of the water tank 11. The inclined design of the sloping trough 12 helps to guide the water flow smoothly and avoid stagnation at the trough opening. In order to remove fine impurities suspended in the water, the water flow needs to pass through the filter plate 14 before discharge or circulation. The filter plate 14 is slidably installed on one side of the frame 1. Its installation position is located on the water flow path of the water tank 11. When the water flows through the filter plate 14, the solid particles are filtered out. The filter plate 14 is positioned by the positioning plate 15 fixedly installed on one side and is fixedly connected to the frame 1 with bolts 16 to ensure its stability under the impact of water flow. When it is necessary to clean or replace the filter plate 14, the bolts 16 can be loosened to pull it out from the frame 1.

[0044] The working principle of a cold rolling and shaping device for processing C-shaped steel:

[0045] The frame 1 forms the main support structure of the device. The metal strip is first guided and conveyed by the conveyor roller group 2 to ensure its smooth entry into the forming station. The metal strip then enters the cold bending forming area composed of the pressure roller group 3. The pressure roller group 3 consists of multiple pairs of horizontally arranged forming rollers. Through its specific roller profile, it applies a continuous lateral bending force to the moving strip, causing its cross-sectional shape to gradually undergo plastic deformation, ultimately forming a C-shaped steel of the preset specifications. During continuous production, in order to overcome the heat problem generated by the high-speed friction of the pressure roller group 3, the cooling component 4 is activated. First, the motor 406 is started, and the motor 406 drives the bidirectional threaded rod 401 to rotate. Since the bidirectional threaded rod 401 is threadedly connected to two moving frames 403, and the moving frames 403 slide simultaneously... The rotational motion is converted into linear motion of two moving frames 403 along the axial direction of the positioning rod 402 in opposite directions. This adjusts the two moving frames 403 to the optimal cooling position covering the working area of ​​the pressure roller group 3. After the cooling position is adjusted, the water pump 6 is started. The water pump 6 pumps the cooling medium through the bellows 7 to the water inlet pipe 5. The cooling medium enters the cavity inside the moving frame 403 through the water inlet pipe 5 and is evenly distributed to each nozzle 404. The nozzle 404 sprays the cooling medium in the form of atomization or jet onto the roller surface and key areas of the working pressure roller group 3 below. After absorbing the frictional heat, the cooling medium flows away, achieving continuous, uniform and direct cooling of the pressure roller group 3, effectively suppressing the temperature rise of the pressure rollers in the pressure roller group 3.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
