Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel strip processing, and in particular to a cold-rolled steel strip slitting device. Background Technology

[0002] A cold-rolled steel strip slitting device is a piece of equipment used to slit cold-rolled steel strips into strips of a specific width. It can cut wide cold-rolled steel strips into multiple strips of smaller width to meet the specific requirements of different industries and products for steel strip width.

[0003] Existing cold-rolled steel strip slitting equipment lacks the function of recovering cutting fluid. Without this function, a large amount of used cutting fluid may be directly discharged, resulting in waste of cutting fluid and increased production costs.

[0004] Therefore, to address the issue that existing cold-rolled steel strip slitting devices lack the function of recovering cutting fluid, which may lead to the direct discharge of large amounts of used cutting fluid, resulting in waste and increased production costs, a new cold-rolled steel strip slitting device can be designed. This device would feature a collection tray to collect used cutting fluid. The collected cutting fluid would flow down a trough through the inclined surface of the collection tray. A filter screen inside the trough would filter out metal scraps. The filtered cutting fluid would then enter a guide chamber and proceed through a water pump. When the water pump is running, it would pump the cutting fluid from the pipe back into the storage tank, thus achieving the purpose of collecting the cutting fluid. Utility Model Content

[0007] Preferably, by setting up a collection tray, the used cutting fluid can be collected. The collected cutting fluid flows down into a drop trough through the inclined surface of the collection tray. Since a filter screen is set up in the drop trough, metal scraps can be filtered out. The filtered cutting fluid enters the first pipeline through the guide chamber, and then a water pump is set up. When the water pump is running, the cutting fluid in the first pipeline is pumped back to the storage tank, thereby achieving the purpose of collecting the cutting fluid. This solves the problem that the existing cold-rolled steel strip slitting device lacks the function of recycling cutting fluid.

[0011] Preferably, a loading bracket is provided on the rear left side of the upper surface of the base, and an external support mechanism is provided on the side of the loading bracket. Each external support plate of the external support mechanism has an installation groove 2 on its outer surface. A roller is rotatably connected inside the installation groove 2.

[0012] Preferably, a waste support is provided on the right rear side of the middle of the upper surface of the base, and a second motor is installed on the right rear surface of the waste support.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a collection tray, used cutting fluid can be collected. The collected cutting fluid flows down the inclined surface of the collection tray into a drop trough. Since a filter screen is installed in the drop trough, metal scraps can be filtered out. The filtered cutting fluid enters pipe one through a guide chamber, and then a water pump one pumps the cutting fluid in pipe one back to the storage tank when it runs.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a cold-rolled steel strip slitting device, including a base 1; it also includes a finished product receiving module 2, a cutting frame 3, a liquid collecting tray 4, a drop trough 5, a filter screen 6, a flow guide chamber 7, a pipe 8, an installation platform 9, a liquid storage tank 10, and a water pump 11. The finished product receiving module 2 is located on the right side of the upper surface of the base 1. The cutting frame 3 is installed on the left side of the middle of the upper surface of the base 1. The liquid collecting tray 4 is located in the middle of the upper surface of the cutting frame 3. A drop trough 5 is formed through the lower left side of the inner surface of the liquid collecting tray 4. A filter screen 6 is installed on the upper side of the inner surface of the drop trough 5. A flow guide chamber 7 is located on the lower surface of the liquid collecting tray 4 below the drop trough 5. The lower surface of the flow guide chamber 7 is... One end of the pipe 8 is connected to the side. An installation platform 9 is installed on the upper side of the rear surface of the cutting frame 3. A liquid storage tank 10 is set on the upper surface of the installation platform 9. A water pump 11 is set on the left side of the upper surface of the liquid storage tank 10. The upper surface of the water pump 11 is connected to the other end of the pipe 8. By setting up a liquid collection tray 4, the used cutting fluid can be collected. The collected cutting fluid flows down the drop trough 5 through the inclined surface of the liquid collection tray 4. Since a filter screen 6 is set up in the drop trough 5, metal scrap can be filtered. The filtered cutting fluid enters the pipe 8 through the guide chamber 7. Then, by setting up the water pump 11, the cutting fluid in the pipe 8 is pumped back to the liquid storage tank 10 when the water pump 11 is running, thereby achieving the purpose of collecting the cutting fluid.

[0024] Please see Figures 1-2In this embodiment, a water pump 12 is installed on the front side of the upper surface of the liquid storage tank 10. One end of a pipe 13 is installed on the upper surface of the water pump 12, and the other end of the pipe 13 is connected to a nozzle 14. By installing the water pump 12, when the water pump 12 is running, it pumps the cutting fluid in the liquid storage tank 10 into the pipe 13, and then the nozzle 14 applies pressure to spray it onto the steel strip, thereby achieving the purpose of lubricating and cooling the steel strip during cutting. The front and rear sides of the cutting frame 3 are provided with mounting grooves 15. A turntable 16 is installed on the front side of the upper surface of the cutting frame 3. The lower surface of the turntable 16 penetrates the upper surface of the cutting frame 3 and is connected to a lead screw 17. The lower surface of the lead screw 17 is connected to the front side of the cutter frame 3. The lower inner surface of the side mounting groove 15 is rotatably connected to the outer surface of the lead screw 17, through which a sliding mounting block 18 is threadedly connected. A drive shaft 19 is rotatably connected to the rear surface of the sliding mounting block 18. A cutter 20 is positioned at the middle of the outer surface of the drive shaft 19. A limit rod 21 is positioned on the lower inner surface of the rear side mounting groove 15. A sliding mounting block 22 is rotatably connected to the outer surface of the limit rod 21. The front surface of the sliding mounting block 22 is rotatably connected to the rear surface of the drive shaft 19. A motor 23 is positioned on the lower rear surface of the cutting frame 3. The output end of the motor 23 is connected to a drive shaft 24 through the rear surface of the cutting frame 3. The front surface of the drive shaft 24... The inner front surface of the cutting frame 3 is rotatably connected to the inner front surface of the transmission shaft 24. A tool 25 is positioned at the middle of the outer surface of the transmission shaft 24. A motor 23 drives the transmission shaft 24 to rotate, which in turn drives the tool 25 to rotate. A turntable 16 rotates, which in turn drives the lead screw 17 to rotate. The lead screw 17, through the cooperation of the limit rod 21 and the sliding mounting block 22, restricts the rotation of the sliding mounting block 18, thereby causing the sliding mounting block 18 to move. The movement of the sliding mounting block 18 drives the transmission shaft 19 and the tool 20 to move. When the transmission shaft 19 moves upwards, it can... A steel strip is placed between the drive shaft 19 and the transmission shaft 24. After placement, the transmission shaft 19 is lowered, and the steel strip is clamped by the transmission shaft 19 and the transmission shaft 24. Then, the motor 23 is started, and the steel strip is pulled outward while being cut, thus achieving the purpose of cutting the steel strip. A rocker arm 26 is provided on the upper surface of the turntable 16. A crank handle 27 is rotatably connected to the side of the upper surface of the rocker arm 26 away from the turntable 16. By setting the rocker arm 26, the torque applied to the turntable 16 can be increased, so that the turntable 16 can be rotated more easily. By setting the crank handle 27, the operator can have a gripping point when rotating the rocker arm 26, thus achieving the purpose of easily rotating the turntable 16.

[0025] Please see Figures 1-4In this embodiment, a loading bracket 28 is provided on the rear left side of the upper surface of the base 1. An external support mechanism 29 is provided on the side of the loading bracket 28. Each external support plate of the external support mechanism 29 has an installation groove 30 on its outer surface. A roller 31 is rotatably connected inside the installation groove 30. By setting the external support mechanism 29, it can be used to install steel strips of different roll sizes. By setting the roller 31, the steel strip can rotate on the surface of the external support mechanism 29 after installation, thereby avoiding the situation where the steel strip roll cannot rotate and gets stuck when pulling. A scrap support 32 is provided on the rear right side of the middle of the upper surface of the base 1. A motor 33 is installed on the right rear surface of the scrap support 32. The output end of the motor 33 passes through the rear surface of the scrap support 32 and is connected to There is a receiving bracket 34. A second motor 33 is installed. When the second motor 33 runs, it drives the receiving bracket 34 to rotate. After the worker fixes the scrap steel strip to the receiving bracket 34, the scrap steel strip can be wound up by the rotation of the receiving bracket 34. An electric push rod 35 is embedded in the left side of the front surface of the scrap bracket 32. The telescopic end of the electric push rod 35 is connected to a limit ring 36. By setting the electric push rod 35, the electric push rod 35 drives the limit ring 36 to move left and right. By passing the scrap steel strip through the center of the limit ring 36, the position of the scrap steel strip also moves when the limit ring 36 moves. This can avoid the receiving bracket 34 winding the scrap steel strip in only one position when winding it up. This achieves the purpose of winding the scrap steel strip evenly at each position of the receiving bracket 34.

[0026] During operation, a water pump 12 pumps the cutting fluid from the storage tank 10 into the pipeline 13, where it is then sprayed onto the steel strip by the nozzle 14 under pressure. This lubrication and cooling of the steel strip during cutting is achieved. A motor 23 drives the transmission shaft 24 to rotate, which in turn drives the cutting tool 25 to rotate. A turntable 16 rotates, causing the lead screw 17 to rotate. The rotation of the lead screw 17 is controlled by a limit rod 21 and a sliding mounting block 2. The cooperation of component 2 restricts the rotation of sliding mounting block 18, thereby driving sliding mounting block 18 to move. When sliding mounting block 18 moves, it drives transmission shaft 19 and cutter 20 to move. When transmission shaft 19 moves upward, a steel strip can be placed between transmission shaft 19 and transmission shaft 24. After placement, transmission shaft 19 is lowered, and the steel strip is clamped by transmission shaft 19 and transmission shaft 24. Then, motor 23 is started, and the steel strip can be pulled outward while cutting, thus achieving the purpose of cutting the steel strip. By setting rocker arm 26, the application can be increased. The torque applied to turntable 16 makes it easier to rotate. The crank handle 27 provides a gripping point for the operator when rotating the rocker arm 26, further facilitating the rotation of turntable 16. The external support mechanism 29 allows for installation on steel strips of different drum sizes. The roller 31 allows the steel strip to rotate on the surface of the external support mechanism 29 after installation, preventing the steel strip from jamming during pulling. The second motor 33 drives the winding mechanism. The material receiving bracket 34 rotates. After the worker fixes the scrap steel strip and the receiving bracket 34, the scrap steel strip can be wound up by rotating the receiving bracket 34. By setting an electric push rod 35, the electric push rod 35 drives the limiting ring 36 to move left and right. By passing the scrap steel strip through the center of the limiting ring 36, the position of the scrap steel strip also moves when the limiting ring 36 moves. This can avoid the receiving bracket 34 winding the scrap steel strip in only one position when winding it up, so as to achieve the purpose of winding the scrap steel strip evenly at each position of the receiving bracket 34.

[0027] Through the above steps, the used cutting fluid can be collected by setting up the collection tray 4. The collected cutting fluid flows down the inclined surface of the collection tray 4 into the drop trough 5. Since the drop trough 5 is equipped with a filter screen 6, metal scrap can be filtered out. The filtered cutting fluid enters the pipeline 8 through the guide chamber 7. Then, by setting up a water pump 11, the water pump 11 pumps the cutting fluid in the pipeline 8 back into the storage tank 10, thereby achieving the purpose of collecting the cutting fluid. This solves the problem that the existing cold-rolled steel strip slitting device lacks the function of recycling cutting fluid. Without the function of recycling cutting fluid, a large amount of used cutting fluid may be directly discharged, resulting in waste of cutting fluid and increased production costs.
