Description

Technical Field

[0001] This utility model belongs to the technical field of cold-rolled steel sheet and hot-rolled coil cutting rack, and particularly relates to a cold-rolled steel sheet and hot-rolled coil cutting rack. Background Technology

[0002] Hot-rolled steel coils possess excellent properties such as high strength, good toughness, ease of processing and forming, and good weldability, making them widely used in shipbuilding, automotive, bridge, construction, machinery, and pressure vessel manufacturing industries. Cold-rolled steel sheets are products made from hot-rolled coils, rolled at room temperature below the recrystallization temperature. Cold-rolled steel sheets are characterized by precise thickness, smooth surface, and superior mechanical properties, and are widely used in automotive manufacturing, electrical products, and other fields.

[0003] For example, Chinese patent CN220636453U discloses a cold-rolled steel sheet / hot-rolled coil cutting frame, including a main component comprising a base plate, a cutting drum, a first mounting plate mounted on the base plate, and a second mounting plate mounted on the base plate; and an adjustment component comprising a first placement groove on the first mounting plate, a motor mounted in the first placement groove, a lead screw mounted on the motor output shaft, a slider mounted on the lead screw, a cutting blade mounted on the slider, through grooves on the upper and lower sides of the cutting drum, first bearings located on both sides of the cutting drum, and a second placement groove on the second mounting plate. This invention, by setting a lead screw and a slider, allows for convenient adjustment of the cutting width, improving adjustment efficiency and cutting width accuracy, and ensuring personnel safety during operation. The second bearing and connecting ring enable synchronous rotation of the cutting drum and the lead screw, ensuring the stability of the cutting blade on the slider during rotation.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has some drawbacks in its use. For example, it can only cut the coil material in one direction, resulting in scraps. It's not convenient to cleverly utilize the remaining material by cutting in another direction; the coil's orientation must be manually adjusted, which is time-consuming and labor-intensive. Therefore, we propose a cold-rolled steel sheet / hot-rolled coil cutting rack. Utility Model Content

[0006] The purpose of this utility model is to provide a cold-rolled steel sheet / hot-rolled coil cutting rack to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a cold-rolled steel sheet / hot-rolled coil cutting rack, comprising:

[0008] The base has two fixed plates fixedly installed on its top. The top of the fixed plates has a groove, and the same supporting rod is placed in the two grooves. A baffle is rotatably installed on the top of the fixed plates.

[0009] Two sets of fixing components are located within two fixing plates and are used to fix the two baffles respectively;

[0010] Two support plates are fixedly installed on the top of the base. A connecting plate is fixedly installed between the two support plates. A T-shaped groove is opened at the bottom of the connecting plate. Two moving rods are slidably installed in the T-shaped groove. A rotating block is rotatably installed in the moving rod. A cutting device is fixedly installed at the bottom end of the rotating block. A through groove is opened on the moving rod. A rectangular rod fixed to the rotating block is provided in the through groove. An electric push rod is fixedly installed on the side of the two support plates that is far apart. The output end of the electric push rod extends through the support plate into the T-shaped groove and is tightly welded to the corresponding moving rod.

[0011] Two sets of limiting components are located inside two moving rods and are used to limit the movement of the two rotating blocks.

[0012] In this technical solution, during use, the fixing component is used to release the baffle from its fixation. Then, the baffle can be rotated and opened. After both baffles are opened, the operator can place the receiving rod in the two grooves. Then, the baffle is rotated and closed, so that the baffle contacts the top of the fixing plate. At this time, the fixing component is used to fix the position of the baffle. The receiving rod will then be limited in the two grooves.

[0013] When the cutting direction needs to be adjusted, the limiting component is used to release the limiting component from the rotating block. The operator can then manually move the rectangular rod to rotate the rotating block 90°. The rectangular rod will slide within the through groove. After the rotating block has rotated completely, the cutting device will also rotate 90°. Subsequently, the limiting component is used again to fix the position of the rotating block. At this point, the cutting direction of both cutting devices can be adjusted, making it more convenient to use and saving time and effort.

[0014] In the above technical solution, the fixing component further includes:

[0015] The second slide is formed inside the fixed plate. A U-shaped pin is slidably installed inside the second slide. One end of the U-shaped pin passes through one side of the second slide and extends into the baffle. The other end of the U-shaped pin is fixedly installed with a tension spring that is fixed to the inner wall of the second slide.

[0016] In this technical solution, the operator first pulls the U-shaped pin, causing one end of the U-shaped pin to be pulled out of the baffle. At this time, the tension spring will extend and generate tension, releasing the baffle from its fixed position. The baffle can then be rotated and opened. After opening both baffles through the above operation, the operator can place the receiving rod in the two grooves, and then rotate and close the baffle, so that the baffle contacts the top of the fixed plate. At this time, under the action of the tension spring, the tension spring will pull one end of the U-shaped pin to move closer to the baffle, causing one end of the U-shaped pin to re-insert into the baffle, thereby limiting the position of the baffle. At this time, the receiving rod will be limited in the two grooves.

[0017] In the above technical solution, one end of the U-shaped pin is further engaged with the baffle.

[0018] In this technical solution, it is ensured that one end of the U-shaped pin can be inserted into the baffle.

[0019] In the above technical solution, the limiting component further includes:

[0020] A sliding groove is provided, which is located inside the moving rod and above the rotating block. A limiting block is slidably installed inside the sliding groove. A rectangular groove is provided on the top of the rotating block. One end of the limiting block passes through the bottom of the sliding groove and extends into the rectangular groove. A handle is fixedly installed on one side of the limiting block. One end of the handle passes through one side of the sliding groove and extends to the outside. A spring is fixedly installed on the top of the limiting block and is fixed to the inner wall of the sliding groove.

[0021] In this technical solution, when the cutting direction needs to be adjusted, the operator can first pull the handle upwards. The handle will cause the limiting block to move upwards. At this time, the spring will be compressed and contract until one end of the limiting block is pulled out of the rectangular groove and fully enters the slide groove. At this time, the limiting block will be released. The operator can then manually move the rectangular rod to make the rotating block rotate 90°. The rectangular rod will slide in the through groove. After the rotating block has rotated completely, the cutting equipment will also rotate 90°. Subsequently, under the action of the spring's rebound force, the spring will push the limiting block downwards until one end of the limiting block is inserted back into the rectangular groove, thereby fixing the position of the rotating block again.

[0022] In the above technical solution, one end of the limiting block is inserted into the rectangular groove, and the handle is slidably connected to the sliding groove.

[0023] In this technical solution, one end of the limiting block is ensured to be inserted into the rectangular groove, so that the handle can slide within the slide groove.

[0024] In the above technical solution, further, a scale line is engraved on one side of the connecting plate, and an L-shaped pointer is fixedly installed on one side of the moving rod, with one end of the L-shaped pointer located on one side of the scale line.

[0025] In this technical solution, it is ensured that the specified width can be accurately cut through the cooperation between the scale lines and the L-shaped pointer.

[0026] In the above technical solution, the output shaft of the electric push rod is further slidably connected to the support plate.

[0027] In this technical solution, it is ensured that the electric linear actuator can operate normally.

[0028] The beneficial effects of this utility model are:

[0029] This cold-rolled steel sheet and hot-rolled coil cutting rack, through the cooperation of the movable rod, slide groove, through groove, rectangular rod, rotating block and limiting components, can directly rotate and adjust the cutting direction of the cutting equipment, eliminating the need for personnel to adjust the orientation of the coil, thus saving more time and effort, and making it more convenient and faster.

[0049] Example 1:

[0050] Please see Figure 1 - Figure 12 As shown, this embodiment provides a cold-rolled steel sheet / hot-rolled coil cutting rack, comprising:

[0051] The base 1 has two fixed plates 2 fixedly installed on its top. The top of the fixed plates 2 has a groove 15, and the same support rod 7 is placed in the two grooves 15. A baffle 8 is rotatably installed on the top of the fixed plates 2.

[0052] Two sets of fixing components are located in the two fixing plates 2 respectively, and are used to fix the two baffles 8 respectively;

[0053] Two support plates 3 are fixedly installed on the top of the base 1. A connecting plate 6 is fixedly installed between the two support plates 3. A T-shaped groove 24 is opened at the bottom of the connecting plate 6. Two moving rods 13 are slidably installed in the T-shaped groove 24. A rotating block 19 is rotatably installed in the moving rod 13. A cutting device 5 is fixedly installed at the bottom end of the rotating block 19. A through groove 12 is opened on the moving rod 13. A rectangular rod 14 fixed to the rotating block 19 is provided in the through groove 12. An electric push rod 4 is fixedly installed on the side of the two support plates 3 that is far apart. The output end of the electric push rod 4 extends through the support plate 3 into the T-shaped groove 24 and is tightly connected to the corresponding moving rod 13.

[0054] Two sets of limiting components are located within the two moving rods 13, and are used to limit the movement of the two rotating blocks 19.

[0055] In use, by using the fixing components, the fixing components can be released from fixing the baffle 8. Then, the baffle 8 can be rotated and opened. After both baffles 8 are opened by the above operation, the operator can place the receiving rod 7 in the two grooves 15. Then, the baffle 8 is rotated and closed, so that the baffle 8 contacts the top of the fixing plate 2. At this time, the fixing components are used to fix the position of the baffle 8. At this time, the receiving rod 7 will be limited in the two grooves 15.

[0056] When the cutting direction needs to be adjusted, the limiting component can be used to release the limiting component on the rotating block 19. The operator can then manually move the rectangular rod 14, causing the rectangular rod 14 to rotate the rotating block 19 by 90°. The rectangular rod 14 will slide within the through groove 12. After the rotating block 19 has rotated completely, the cutting device 5 will also rotate by 90°. Subsequently, the limiting component will be used again to fix the position of the rotating block 19. At this point, the cutting direction of the two cutting devices 5 will be adjusted, making it more convenient to use and saving time and effort.

[0057] Example 2:

[0058] This embodiment provides a cold-rolled steel sheet / hot-rolled coil cutting rack, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0059] The second slide 21 is formed inside the fixed plate 2. A U-shaped pin 23 is slidably installed inside the second slide 21. One end of the U-shaped pin 23 passes through one side of the second slide 21 and extends into the baffle 8. The other end of the U-shaped pin 23 is fixedly installed with a tension spring 22 that is fixed to the inner wall of the second slide 21.

[0060] First, the worker pulls the U-shaped pin 23, causing one end of the U-shaped pin 23 to be pulled out of the baffle 8. At this time, the tension spring 22 will extend and generate tension, and the baffle 8 will be released from its fixed position. It can be rotated and opened. After both baffles 8 are opened through the above operation, the worker can place the receiving rod 7 in the two grooves 15, and then rotate and close the baffle 8 so that the baffle 8 contacts the top of the fixing plate 2. At this time, under the action of the tension spring 22, the tension spring 22 will pull one end of the U-shaped pin 23 to move closer to the baffle 8, so that one end of the U-shaped pin 23 is inserted into the baffle 8 again, thereby limiting the position of the baffle 8. At this time, the receiving rod 7 will be limited in the two grooves 15.

[0061] Example 3:

[0062] This embodiment provides a cold-rolled steel sheet and hot-rolled coil cutting rack. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the U-shaped pin 23 is inserted and engaged with the baffle 8.

[0063] Specifically, it is ensured that one end of the U-shaped pin 23 can be inserted into the baffle 8.

[0064] Example 4:

[0065] This embodiment provides a cold-rolled steel sheet / hot-rolled coil cutting rack, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0066] A slide 16 is formed inside the moving rod 13 and located above the rotating block 19. A limiting block 18 is slidably installed inside the slide 16. A rectangular groove 20 is formed on the top of the rotating block 19. One end of the limiting block 18 passes through the bottom of the slide 16 and extends into the rectangular groove 20. A handle 11 is fixedly installed on one side of the limiting block 18. One end of the handle 11 passes through one side of the slide 16 and extends to the outside. A spring 17 is fixedly installed on the top of the limiting block 18 and is fixed to the inner wall of the slide 16.

[0067] When the cutting direction needs to be adjusted, the operator can first pull the handle 11 upwards. The handle 11 will cause the limiting block 18 to move upwards. At this time, the spring 17 will be compressed and contract until one end of the limiting block 18 is pulled out from the rectangular groove 20 and fully enters the slide groove 16. At this time, the limiting block 18 will be released from its limiting position. The operator can then manually move the rectangular rod 14, causing the rectangular rod 14 to rotate the rotating block 19 by 90°. The rectangular rod 14 will slide in the through groove 12. After the rotating block 19 has finished rotating, the cutting device 5 will also rotate 90°. Subsequently, under the action of the spring 17's rebound force, the spring 17 will push the limiting block 18 downwards until one end of the limiting block 18 is inserted back into the rectangular groove 20, thereby fixing the position of the rotating block 19 again.

[0068] Example 5:

[0069] This embodiment provides a cold-rolled steel sheet and hot-rolled coil cutting rack. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the limiting block 18 is inserted into the rectangular groove 20, and the handle 11 is slidably connected to the slide groove 16.

[0070] Specifically, it ensures that one end of the limiting block 18 can be inserted into the rectangular groove 20, and that the handle 11 can slide within the slide groove 16.

[0071] Example 6:

[0072] This embodiment provides a cold-rolled steel sheet and hot-rolled coil cutting rack. In addition to the technical solutions of the above embodiments, it also has the following technical features: a scale line 9 is engraved on one side of the connecting plate 6, and an L-shaped pointer 10 is fixedly installed on one side of the moving rod 13, with one end of the L-shaped pointer 10 located on one side of the scale line 9.

[0073] This ensures that the specified width can be accurately cut through the cooperation between the scale line 9 and the L-shaped pointer 10.

[0074] Example 7:

[0075] This embodiment provides a cold-rolled steel sheet and hot-rolled steel coil cutting rack. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of the electric push rod 4 is slidably connected to the support plate 3.

[0076] Among these measures, it is essential to ensure that the electric push rod 4 can operate normally.

[0077] Working principle: In use, the operator first pulls the U-shaped pin 23, so that one end of the U-shaped pin 23 is pulled out from the baffle 8. At this time, the tension spring 22 will extend and generate tension, and the baffle 8 will be released from fixation. It can be rotated and opened. After opening both baffles 8 through the above operation, the operator can place the receiving rod 7 in the two grooves 15, and then rotate and close the baffle 8 so that the baffle 8 contacts the top of the fixing plate 2. At this time, under the action of the tension spring 22, the tension spring 22 will pull one end of the U-shaped pin 23 to move closer to the baffle 8, so that one end of the U-shaped pin 23 is inserted into the baffle 8 again, thereby limiting the position of the baffle 8. At this time, the receiving rod 7 will be limited in the two grooves 15.

[0078] When the cutting width needs to be adjusted, the operator can activate two electric push rods 4. The output shafts of the two electric push rods 4 will drive the two moving rods 13 to move, and the two moving rods 13 will drive the two L-shaped pointers 10 to move. According to the scale line 9 on the connecting plate 6, the zero mark on the scale line 9 is located in the middle. The values ​​on both sides of the zero mark continuously increase, so that the operator can accurately adjust the distance between the two cutting devices 5 to ensure that the cutting width meets the standard. Activate the two cutting devices 5, pull one end of the cold-rolled steel plate and hot-rolled coil, and the two cutting devices 5 will cut the cold-rolled steel plate and hot-rolled coil.

[0079] When the cutting direction needs to be adjusted, the operator can first pull the handle 11 upwards. The handle 11 will cause the limiting block 18 to move upwards. At this time, the spring 17 will be compressed and contract until one end of the limiting block 18 is pulled out from the rectangular groove 20 and fully enters the slide groove 16. At this time, the rotating block 19 will be released from its limit. The operator can then manually move the rectangular rod 14 to make the rectangular rod 14 drive the rotating block 19 to rotate 90°. The rectangular rod 14 will slide in the through groove 12. After the rotating block 19 has rotated completely, the cutting device 5 will also rotate 90°. Subsequently, under the action of the spring 17's rebound force, the spring 17 will push the limiting block 18 downwards until one end of the limiting block 18 is inserted back into the rectangular groove 20, thereby fixing the position of the rotating block 19 again. At this time, the cutting direction of the two cutting devices 5 will be adjusted, making it more convenient to use and saving time and effort.

[0080] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
