In the existing technology, the specifications of iron sheet are fixed, and the iron sheet needs to be cut according to actual conditions when used. Currently, special scissors are generally used for cutting. However, no matter how the scissors structure changes, they can only perform intermittent cutting operations, resulting in low cutting efficiency. At the same time, since the consistency of the cutting positions before and after cannot be guaranteed, burrs are very likely to appear on the cutting edges. Utility Model Content

[0003] The main purpose of this application is to provide a cutting device for iron sheets, aiming to solve the defect of low cutting efficiency in the prior art.

[0004] This application achieves the above objectives through the following technical solutions:

[0012] Optionally, a support platform is further provided on the cutting table, and the driven shaft is rotatably connected to the support platform via a rolling bearing; the cutting edge of the second cutting blade is flush with the top surface of the support platform.

[0013] Optionally, the first cutting disc and the second cutting disc both include a disc body, and a cutting edge with a conical structure is integrally connected to the outer circumference of the disc body.

[0014] Optionally, a plurality of cutting teeth are provided on the cutting edge of the first cutting disc around the axis of the first cutting disc.

[0015] Optionally, the support frame includes a column and a cantilever beam, one end of the column is connected to the cutting table, and the other end is connected to the cantilever beam in an L-shaped structure; the cantilever beam is provided with a storage cavity for accommodating the rolling bearing and the rotating shaft.

[0016] Optionally, a limit block 13 is provided on the rotating shaft, and a fixing plate is threadedly connected to the rotating shaft. The limit block 13 and the fixing plate clamp and fix the first cutting disc on the rotating shaft.

[0017] Optionally, a plurality of plug holes are provided on the limit block 13 around the axis of the rotating shaft, and a plurality of plug rods are provided on the first cutting disc, and each of the plug rods is respectively inserted into each of the plug holes.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] The present application includes a cutting table, wherein the cutting table is provided with a support frame, and a first cutting blade is rotatably provided on the support frame; a second cutting blade is also rotatably provided on the cutting table, and the first cutting blade and the second cutting blade are staggered along the axis of the first cutting blade, and the cutting edges of the first cutting blade and the second cutting blade fit together; a driving module is also provided on the cutting table, and the driving module is connected to the first cutting blade;

[0020] During use, the driving module drives the first cutting blade to rotate, and the iron sheet to be cut is placed between the first cutting blade and the second cutting blade. Since the first cutting blade and the second cutting blade are staggered along the axis of the first cutting blade, and the cutting edges of the first cutting blade and the second cutting blade fit together, the above structure is similar to a scissors structure. At the same time, the rotation of the first cutting blade drives the second cutting blade to rotate synchronously in the opposite direction. The synchronously rotating first cutting blade and the second cutting blade will cut the iron sheet from the upper and lower sides at the same time, thereby realizing the shearing of the iron sheet.

[0021] The scissors in the prior art need to be opened again after the blade is closed before they can cut again. Therefore, during the cutting process, opening the blade is a necessary process, but it cannot complete the cutting, which results in the scissors only being able to perform intermittent cutting operations.

[0022] The present application replaces the cutting edge of traditional scissors by continuously rotating the first cutting disc and the second cutting disc. The high-speed rotating first cutting disc and the second cutting disc are synchronously separated during the continuous closing and cutting process. Therefore, the step of closing and then opening the scissors again can be omitted, thereby achieving continuous cutting of iron sheets and improving cutting efficiency as much as possible.

[0023] Secondly, the first cutting shear disc and the second cutting shear disc of the present application can both be driven by a driving module, which helps to reduce the difficulty of using the device and makes the device more convenient to operate.

[0024] Finally, since the present application performs continuous cutting through the rotating first cutting disc and the second cutting disc, it can effectively ensure the flatness of cutting, which is conducive to improving the cutting quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Implementation Method 1

[0037] Reference Figures 1 to 5This embodiment, as an optional embodiment of the present application, discloses a cutting device for iron sheets, comprising a cutting table 1, wherein the cutting table 1 is provided with a support frame 2, wherein the support frame 2 comprises a column 201 and a cantilever beam 202, wherein one end of the column 201 is connected to the cutting table 1, and the other end thereof is connected to the cantilever beam 202 in an L-shaped structure; a cavity is provided on the cantilever beam 202;

[0038] The cutting device also includes a first cutting blade 3. A plurality of rolling bearings are provided in the cavity of the cantilever beam 202. The rolling bearings are connected in series via a rotating shaft 5. Both ends of the rotating shaft 5 extend out of the cavity. A driving module is also provided on the column 201. The driving module includes a driving motor 6. The output shaft of the driving motor 6 is dynamically connected to one end of the rotating shaft 5 via a coupling.

[0039] A limit block 13 is further provided at the other end of the rotating shaft 5. The first cutting disc 3 includes a disc body 10. A conical cutting edge 11 is integrally connected to the outer circumference of the disc body 10. A mounting hole is further provided on the disc body 10. The rotating shaft 5 is inserted into the mounting hole. At the same time, along the axial direction of the rotating shaft 5, the limit block 13 is tightly fitted with the side surface of the disc body 10. A fixing plate 14 is also threadedly connected to the rotating shaft 5. The fixing plate 14 is tightly fitted with the other side surface of the disc body 10.

[0040] In the above structure, the limit block 13 and the fixing plate 14 are respectively placed on both sides of the first cutting disc 3, thereby clamping and fixing the first cutting disc 3 on the rotating shaft 5. It is not only simple in structure but also easy to assemble and disassemble, which is conducive to improving the maintenance efficiency of the equipment.

[0041] Furthermore, the axis of the rotating shaft 5 is sleeved, and a plurality of plug holes 15 are provided on the limit block 13. A plurality of plug rods 16 are provided on the first cutting disc 3, and each of the plug rods 16 is respectively inserted into each of the plug holes 15. It should be noted that it is preferred that 2-4 plug holes 15 are provided. If two are provided, the angle between the two plug holes 15 is 180°. If three are provided, the angle between any two adjacent plug holes 15 is 120°.

[0042] The mating rod 16 and the mating hole 15 that cooperate with each other abut against each other in the axial direction around the rotating shaft 5, which can better transmit the torque of the rotating shaft 5, avoid relative slippage between the first cutting disc 3 and the rotating shaft 5, and improve the stability and reliability of the equipment.

[0043] It should be noted that a plurality of cutting teeth 12 are provided on the cutting edge 11 of the first cutting disc 3 around the axis of the first cutting disc 3; the provision of the cutting teeth 12 enables faster cutting of the iron sheet, thereby improving cutting efficiency;

[0044] At the same time, a support platform 9 is further provided on the cutting table 1, and the support platform 9 is provided directly below the cantilever beam 202. A driven shaft 7 is rotatably connected to the support platform 9 through a rolling bearing, and a second cutting shear disk 4 is provided on the driven shaft 7. The structure of the second cutting shear disk 4 is the same as that of the first cutting shear disk 3, and both include a disk body 10 and a cutting edge 11 integrally connected to the disk body 10. It should be noted that the cutting edges 11 of the first cutting shear disk 3 and the second cutting shear disk 4 are both conical structures, and the cross-section of the cutting edge 11 can also be set to an isosceles triangle structure;

[0045] At the same time, the cutting edge 11 of the second cutting blade 4 is flush with the top surface of the support platform 9;

[0046] Along the axial direction of the rotating shaft 5, the first cutting shear disc 3 and the second cutting shear disc 4 are staggered, and at the same time, the first cutting shear disc 3 and the second cutting shear disc 4 facing each other are in contact with each other to ensure that the first cutting shear disc 3 can drive the second cutting shear disc 4 to rotate through friction; at the same time, in order to improve the wear resistance of the first cutting shear disc 3 and the second cutting shear disc 4, a wear-resistant coating can also be provided on the side that is in contact with each other.

[0047] Furthermore, the driven shaft 7 extends to the lower side of the driving motor 6, and a driving gear 8 is provided on the driven shaft 7 and the rotating shaft 5, and the two driving gears 8 are meshed with each other;

[0048] The driving gear 8 can directly drive the second cutting disc 4. On the one hand, it can effectively increase the rotation speed of the second cutting disc 4, thereby improving the cutting smoothness and cutting efficiency. On the other hand, the second cutting disc 4 is no longer driven by friction, which is beneficial to reduce the wear of the first cutting disc 3 and the second cutting disc 4, thereby extending the service life of the equipment.

[0049] The scissors in the prior art need to be opened again after the blade is closed before they can cut again. Therefore, during the cutting process, opening the blade is a necessary process, but it cannot complete the cutting, which results in the scissors only being able to perform intermittent cutting operations.

[0050] The present application replaces the cutting edge of traditional scissors by continuously rotating the first cutting disc and the second cutting disc. The high-speed rotating first cutting disc and the second cutting disc are synchronously separated during the continuous closing and cutting process. Therefore, the step of closing and then opening the scissors again can be omitted, thereby achieving continuous cutting of iron sheets and improving cutting efficiency as much as possible.

[0051] Secondly, the first cutting shear disc and the second cutting shear disc of the present application can both be driven by a driving module, which helps to reduce the difficulty of using the device and makes the device more convenient to operate.

[0052] Finally, since the present application performs continuous cutting through the rotating first cutting disc and the second cutting disc, it can effectively ensure the flatness of cutting, which is conducive to improving the cutting quality.

[0053] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
