The roll forming device and the shearing device are installed on the frame. After the roll forming device rolls and forms the sheet metal, it transports the sheet metal to the shearing device, and the shearing device shears the sheet metal into the required specifications.

[0003] In the related art, the shearing device includes a mounting frame, an upper knife seat, a lower knife seat, an upper knife, a lower knife, and an oil cylinder. The mounting frame is installed on the frame of the roll forming machine. The upper knife seat and the lower knife seat are arranged in a staggered manner, and the upper knife seat is located above the lower knife seat. The upper knife seat is slidably connected to the mounting frame and the upper knife is fixedly connected to the upper knife seat. The lower knife seat is fixedly connected to the mounting frame and the lower knife is fixedly connected to the lower knife seat. The oil cylinder is fixedly connected to the upper end of the mounting frame and the power output shaft is connected to the upper knife seat to drive the upper knife seat to approach or move away from the lower knife seat, so as to cooperate with the upper knife and the lower knife to complete the shearing of the sheet metal.

[0004] In practical applications, after the roll forming machine is assembled, it is transported through a box. Since the oil cylinder is located at the upper end of the mounting frame, the height of the shearing device is the sum of the lengths of the mounting frame and the oil cylinder, resulting in a relatively high height of the shearing device, that is, the overall height of the roll forming machine is relatively high, making it difficult to pass through some culverts and affecting transportation.

[0032] References herein to "embodiments" mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] The following further describes the present application in conjunction with the attached Figure 1-2 drawings for a more detailed description.

[0034] An embodiment of the present application discloses a shearing device for sheet metal forming.

[0035] Referring to Figure 1 , the shearing device includes a mounting base 1, two driving members 2, an upper tool holder 3, a lower tool holder 4, an upper tool 5, and a lower tool 6. The mounting base 1 includes a mounting plate 11. In this embodiment, the driving member 2 is an oil cylinder. In other embodiments, the driving member 2 can also be a cylinder, an electric push cylinder, etc. The two driving members 2 are vertically and fixedly connected to the upper side of the mounting plate 11, and the two driving members 2 are arranged at intervals along the length direction of the mounting plate 11.

[0036] The upper tool holder 3 is located above the mounting plate 11, and the power output shafts of the two driving members 2 are respectively fixedly connected to both ends of the upper tool holder 3. When the two driving members 2 work, they can drive the upper tool holder 3 to move in the vertical direction. At the same time, the upper tool 5 is fixedly connected to the lower side of the upper tool holder 3. The lower tool holder 4 is fixedly connected to the upper side of the mounting plate 11, and the lower tool holder 4 is arranged in a staggered manner with the upper tool holder 3. At the same time, the lower tool 6 is fixedly connected to the lower tool holder 4.

[0037] In practical applications, the sheet metal passes between the upper tool 5 and the lower tool 6. The two driving members 2 drive the upper tool holder 3 to move in the vertical direction, so that the upper tool holder 3 approaches or moves away from the lower tool holder 4, enabling the staggered upper tool 5 and lower tool 6 to cooperate to complete the shearing of the sheet metal. Among them, since the two driving members 2 are arranged on the upper side of the mounting plate 11 to make full use of the space of the mounting base 1, the overall height of the shearing device can be effectively reduced, thus facilitating the transportation of the roll forming machine.

[0038] In some embodiments, the mounting base 1 further includes two guide posts 12. Both of the two guide posts 12 are cylindrical. The two guide posts 12 are fixedly connected to the upper side of the mounting plate 11 and are arranged at intervals along the length direction of the mounting plate 11. Both ends of the upper tool holder 3 are respectively sleeved on the two guide posts 12, so that the upper tool holder 3 is slidably connected to the two guide posts 12 at the same time, improving the stability of the upper tool holder 3 moving in the vertical direction, enabling the upper tool 5 to cooperate with the lower tool 6 more stably, and thus improving the stability of sheet metal shearing.

[0039] In some embodiments, the mounting plate 11 further includes a limiting plate 13 which is fixedly connected to the upper ends of the two guiding columns 12. After the driving member 2 drives the upper knife holder 3 to move upward by a certain distance, the limiting plate 13 abuts against the upper side of the upper knife holder 3 to limit the further movement of the upper knife holder 3, which can effectively prevent the upper knife holder 3 from disengaging from the two guiding columns 12, thereby improving the working stability of the shearing device.

[0040] In some embodiments, the limiting plate 13 is detachably connected to the two guiding columns 12, so that the limiting plate 13 can be disassembled, thereby facilitating the installation and disassembly of the upper knife holder 3, facilitating the maintenance of the upper knife holder 3, and facilitating the installation and disassembly of the upper knife 5.

[0041] In some embodiments, the mounting seat 1 further includes two fastening bolts 14. The two guiding columns 12 pass through the limiting plate 13 and abut against the lower side of the limiting plate 13 to place the limiting plate 13. At the same time, the two fastening bolts 14 are respectively threadedly connected to the upper ends of the two guiding columns 12 and abut against the upper side of the limiting plate 13 to fix the limiting plate 13, that is, to realize the detachable connection between the limiting plate 13 and the two guiding columns 12, with a simple structure and convenient operation.

[0042] Referring to Figure 1 and Figure 2 , in some embodiments, the limiting plate 13 is provided with a relief groove 15 along its own length direction, so that the two fastening bolts 14 are located in the relief groove 15, enabling the overall height of the shearing device to be further reduced, and the reduced height is the length of the fastening bolts 14.

[0043] Referring to Figure 1 , in some embodiments, the shearing device further includes two mounting blocks 7. The two mounting blocks 7 are fixedly connected to both ends of the upper knife holder 3, and the power output shafts of the two driving members 2 are fixedly connected to the two mounting blocks 7 through bolts, so as to facilitate the connection between the two driving members 2 and both ends of the upper knife holder 3.

[0044] The implementation principle of this embodiment is as follows: in practical applications, the sheet passes through the upper knife 5 and the lower knife 6. The two driving members 2 drive the upper knife holder 3 to move in the vertical direction, so that the upper knife holder 3 approaches or moves away from the lower knife holder 4, enabling the misaligned upper knife 5 and lower knife 6 to cooperate to complete the shearing of the sheet. Among them, since the two driving members 2 are arranged on the upper side of the mounting plate 11 to make full use of the space of the mounting seat 1, the overall height of the shearing device can be effectively reduced, thereby facilitating the transportation of the roll forming machine.

[0045] The embodiment of the present application also discloses a roll forming machine.

[0046] The roll forming machine includes the shearing device described in the above embodiment.

[0047] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
