Detailed implementation manners

[0024] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0025] The cold-rolled steel coil cutting device according to the embodiment of the present application will be described below with reference to the drawings.

[0026] As Figures 1 - 5 shown, the cold-rolled steel coil cutting device according to the embodiment of the present application may include: a conveying frame 1, a supporting mechanism 2, a cutting mechanism 3, and a driving device 4.

[0027] Among them, the conveying frame 1 is vertically placed relative to the ground.

[0028] It should be noted that in this embodiment, the conveying frame 1 and the ground are supported by legs, and the legs can reduce the contact area between the conveying frame 1 and the ground, thereby increasing the pressure between the two and ensuring the stability of the device during use.

[0029] The supporting mechanism 2 includes a rod assembly 21 and a plurality of supporting wheels 22.

[0030] Among them, both ends of the rod assembly 21 are respectively connected to the conveying frame 1, and a plurality of supporting wheels 22 are respectively connected to the rod assembly 21 through a plurality of adjusting components 24, and grooves 23 are provided on the supporting wheels 22.

[0031] It should be noted that the groove 23 described in this embodiment is arranged in an annular structure.

[0032] The cutting mechanism 3 includes a first rod body 31 and a plurality of cutting wheels 32.

[0033] Wherein, both ends of the first rod body 31 are respectively rotatably connected to the conveying frame 1, a plurality of cutting wheels 32 are slidably sleeved outside the first rod body 31, the plurality of cutting wheels 32 are arranged opposite to the plurality of supporting wheels 22, and the cutting edge of the cutting wheel 32 extends into the interior of the groove 23.

[0034] One end of the first rod body 31 penetrates through one side of the conveying frame 1, the output shaft of the driving device 4 is connected to one end of the first rod body 31, and the driving device 4 is installed on the rod body assembly 21.

[0035] It should be noted that the conveying frame 1 described in this embodiment is arranged between two external devices, for example: a steel coil uncoiling or rewinding device.

[0036] Specifically, using this equipment to perform a slitting operation on a cold-rolled steel coil, the cold-rolled steel coil is conveyed on the conveying frame 1, passes between the supporting mechanism 2 and the cutting mechanism 3, the driving device 4 drives the first rod body 31 to rotate, the first rod body 31 drives the plurality of cutting wheels 32 to rotate, the cutting wheels 32 and the supporting wheels 22 act together on the cold-rolled steel coil, the cutting edge of the cutting wheel 32 extends into the groove 23 on the supporting wheel 22, and during the cutting process, the groove 23 can play a role in guiding and protecting the cutting tool 322, thereby improving the cutting accuracy of the steel coil.

[0037] According to production requirements, relevant technicians need to adjust the position of the cutting wheel 32. First, the relevant technicians ensure that the operation process is carried out under the condition of shutdown. By adjusting the component 24, the position of the supporting wheel 22 on the rod body assembly 21 is changed. Since the cutting edge of the cutting wheel 32 extends into the groove 23 on the supporting wheel 22, the supporting wheel 22 interferes with the cutting wheel 32. The relevant technicians push the supporting wheel 22, and the cutting wheel 32 and the supporting wheel 22 move together, thereby changing the position of the cutting wheel 32. After the position is determined, the supporting wheel 22 is fixed by using the adjusting component 24. During the whole process, the operator is far away from the cutting wheel 32, thereby improving the safety when adjusting the cutting tool.

[0038] In an embodiment of the present application, as Figure 2 shown, the rod body assembly 21 includes a second rod body 211 and two connecting components 212.

[0039] Wherein, the supporting wheel 22 is arranged on the second rod body 211, two connecting components 212 are respectively arranged at both ends of the second rod body 211, and the connecting components 212 are connected to the conveying frame 1.

[0040] In an embodiment of the present application, asFigure 2 As shown, the connecting component 212 includes a rotating part 2121, an extension rod 2122, a frame body 2123, and a hand-operated screw 2124.

[0041] Wherein, one side of the rotating part 2121 is connected to one end of the second rod body 211, one end of the extension rod 2122 is connected to the other side of the rotating part 2121, the frame body 2123 is arranged on the outer wall of the conveying rack 1, the other end of the extension rod 2122 extends into the interior of the frame body 2123, the hand-operated screw 2124 is rotatably connected to the frame body 2123, and the hand-operated screw 2124 is threadedly connected to the extension rod 2122.

[0042] It should be noted that both the second rod body 211 and the first rod body 31 described in this embodiment are square rods. The square rods can not only drive the supporting wheels 22 and the cutting wheels 32 to rotate, but also facilitate their sliding on the corresponding second rod body 211 and first rod body 31.

[0043] It can be understood that setting the connecting component 212 can change the distance between the supporting wheel 22 and the cutting wheel 32. On the one hand, it is convenient for loading the cold-rolled steel coil. On the other hand, when the supporting wheel 22 and the cutting wheel 32 rotate, they can apply a force to the surface of the cold-rolled steel coil, avoiding the situation of bending at the cutting position and ensuring the stability of cutting.

[0044] Specifically, rotate the two hand-operated screws 2124. Since the hand-operated screws 2124 are threadedly connected to the extension rod 2122, the extension rod 2122 drives the rotating part 2121 and the second rod body 211 to move, increasing the distance between the supporting wheel 22 and the cutting wheel 32. The cold-rolled steel coil passes through the space between the supporting wheel 22 and the cutting wheel 32. Rotate the two hand-operated screws 2124 in the reverse direction to reduce the distance between the supporting wheel 22 and the cutting wheel 32, and the cutting edge of the cutting wheel 32 extends into the groove 23, and the supporting wheel 22 applies a certain force to the cold-rolled steel coil (this working condition can be obtained through a pressure sensor).

[0045] In an embodiment of the present application, as Figure 3 shown, the adjusting component 24 includes a sleeve 241 and a fixing member 242.

[0046] Wherein, a guide groove 240 is formed on the outer wall of the second rod body 211. One end of the guide groove 240 is arranged in an open structure. The sleeve 241 is sleeved outside the second rod body 211. One end of the sleeve 241 is connected to one side of the supporting wheel 22, and the fixing member 242 is arranged on the sleeve 241. One end of the fixing member 242 extends into the interior of the guide groove 240.

[0047] As a possible situation, in order to prevent the fixing member 242 from loosening, a rubber layer can be arranged inside the guide groove 240. The fixing member 242 abuts against the rubber layer, and a force can be applied to it to prevent the fixing member 242 from loosening during the operation of the device.

[0048] It can be understood that one end of the guide groove 240 is arranged in an open structure, which can facilitate the detachment of the support wheel 22 from the second rod body 211 when it is damaged.

[0049] In an embodiment of the present application, as Figure 2 shown, the cutting wheel 32 includes a central wheel 321 and a cutting blade body 322.

[0050] Among them, the central wheel 321 is slidably sleeved on the outer side of the first rod body 31, the cutting blade body 322 is sleeved on the outer side of the central wheel 321, and the cutting edge of the cutting blade body 322 is adapted to the groove 23.

[0051] It should be noted that in this embodiment, the cutting blade body 322 is sleeved on the outer side of the central wheel 321, and the two are connected in a detachable manner, which is convenient for replacing the cutting blade body 322 when it is damaged.

[0052] In an embodiment of the present application, as Figure 1 and Figure 5 shown, it further includes an auxiliary trimming mechanism 5. The auxiliary trimming mechanism 5 includes a grinding component 51, a transmission component 52 and a collection component 53.

[0053] Among them, the grinding component 51 includes a housing 511 and a plurality of ridges 512. Among them, the housing 511 has a cylindrical structure, the housing 511 is rotatably connected to the conveying frame 1, a plurality of through holes 513 are formed in the housing 511, and a plurality of ridges 512 are respectively arranged on the outer wall of the housing 511, and the plurality of ridges 512 and the plurality of through holes 513 are arranged at intervals.

[0054] It should be noted that the ridges 512 described in this embodiment are made of abrasive materials, and the through holes 513 are located between two ridges 512, and can collect the metal particles generated by grinding inside the housing 511.

[0055] The transmission component 52 includes a driving sprocket 521, a driven sprocket 522 and a chain 523. Among them, the driving sprocket 521 is installed between the first rod body 31 and the output shaft of the driving device 4, the driven sprocket 522 is installed at one end of the housing 511, the diameter of the driving sprocket 521 is larger than the diameter of the driven sprocket 522, and the chain 523 is wound around the driving sprocket 521 and the driven sprocket 522.

[0056] It should be noted that in this embodiment, the diameter of the driving sprocket 521 is larger than that of the driven sprocket 522, that is, the rotational speed of the grinding assembly 51 is greater than the moving speed of the cold-rolled steel coil, so that there is relative movement between the grinding assembly 51 and the cold-rolled steel coil.

[0057] The collecting assembly 53 includes an aggregator 531 and a pipe body 532. Among them, the aggregator 531 is installed on the outer wall of the conveying frame 1, and one end of the pipe body 532 is communicated with the housing 511 and one end of the aggregator 531.

[0058] It should be noted that the aggregator 531 described in this embodiment has been disclosed in the prior art. The aggregator 531 can form a negative pressure inside the pipe body 532 by means of suction. The pipe body 532 extends into the housing 511 to collect the metal particles entering the housing 511.

[0059] As a possible situation, there will inevitably be a small part of metal burrs on the cold-rolled steel coil after slitting. The auxiliary trimming mechanism 5 can grind this part of the metal burrs to ensure the quality of the narrow strip of the steel coil.

[0060] During the grinding and trimming of the slit cold-rolled steel coil, the gravity of the cold-rolled steel coil itself is used to pull it to fit on the outside of the housing 511, so that there is a certain acting force between the two, thereby ensuring the grinding effect.

[0061] In an embodiment of the present application, as Figure 1 and Figure 4 shown, it includes a limiting mechanism 6. The limiting mechanism 6 includes a limiting roller shaft 61 and two groups of pressing components 62.

[0062] Among them, the limiting roller shaft 61 is located above a conveying roller shaft of the conveying frame 1. The two groups of pressing components 62 are respectively connected to the conveying frame 1, and the limiting roller shaft 61 is rotatably connected to the pressing components 62.

[0063] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the pressing component 62 includes a cover body 621, a slider 623 and a spring 624.

[0064] Among them, the cover body 621 is connected to the conveying frame 1. A through groove 622 is opened on the outer wall of the cover body 621. The slider 623 is slidably arranged inside the cover body 621. The spring 624 is arranged between the slider 623 and the top wall of the cover body 621. One end of the limiting roller shaft 61 penetrates through the through groove 622, and one end of the limiting roller shaft 61 is rotatably connected to the slider 623.

[0065] It should be noted that during the slitting process of cold-rolled steel coils, due to the characteristics of the cold-rolled steel coils themselves, there is a certain tension fluctuation effect. Before the cold-rolled steel coil is cut, it is restricted by the limiting mechanism 6 to eliminate the influence of the tension fluctuation on the cutting effect.

[0066] Specifically, the cold-rolled steel coil is placed below the limiting roller shaft 61, and one of the conveying roller shafts on the conveying rack 1 plays an auxiliary role. The elastic potential energy of the spring 624 is used to push the slider 623, and the slider 623 drives the limiting roller shaft 61 to apply a force to the cold-rolled steel coil, thereby playing a limiting role.

[0067] In summary, for the cold-rolled steel coil cutting equipment of the embodiment of the present application, through the combined action of the supporting mechanism and the cutting mechanism on the steel coil, the cutting edge of the cutting wheel extends into the groove. During the cutting process, the groove can play a guiding and protecting role for the cutting tool, thereby improving the cutting accuracy of the steel coil; in addition, when adjusting the position of the cutting wheel, by pushing the supporting wheel, the supporting wheel interferes with the cutting wheel, thereby driving the cutting wheel to move to the preset position. During the whole process, the operator is far away from the cutting wheel, thereby improving the safety when adjusting the cutting tool.
