Detailed implementation manners
[0033] The following further describes the present application in detail with reference to the Figures 1-3 accompanying drawings.
[0034] An embodiment of the present application discloses a plate cutting device.
[0035] Referring to Figure 1 and Figure 2 , the plate cutting device includes a frame 1, a mounting bracket 2, a tool holder 3, an upper knife 4, a lower knife 5 and an adjustment assembly 6. Both sides of the lower end of the mounting bracket 2 are rotatably connected to the frame 1, the tool holder 3 is slidably connected in the mounting bracket 2, and the sliding direction of the tool holder 3 is the width direction of the mounting bracket 2. The upper knife 4 is fixedly connected to the tool holder 3, the lower knife 5 is fixedly connected to the frame 1, the upper knife 4 is located above the lower knife 5, and the upper knife 4 and the lower knife 5 are arranged in a staggered manner. Among them, the tool holder 3 is connected to the crank and connecting rod mechanism 7, so that the tool holder 3 drives the upper knife 4 to reciprocally approach the lower knife 5 to complete the cutting of the plate.
[0036] The adjustment assembly 6 includes a rotating shaft 61, two eccentric wheels 62, a worm and worm gear reducer 63 and an elastic member 64. The rotating shaft 61 is parallel to the axis of rotation of the mounting bracket 2 and is close to the upper end of the mounting bracket 2. The rotating shaft 61 is rotatably connected to the frame 1 and is located on one side of the mounting bracket 2. The two eccentric wheels 62 are respectively fixedly connected to both ends of the rotating shaft 61. The eccentric wheels 62 are eccentrically arranged with the rotating shaft 61 and abut against the mounting bracket 2. The worm and worm gear reducer 63 is fixedly connected to the outside of the frame 1, and the rotating shaft 61 extends to the worm of the worm and worm gear reducer 63, so that the rotating shaft 61 is coaxially fixedly connected to the worm.
[0037] In this embodiment, the elastic member 64 is a disc spring and the number is two. The two elastic members 64 are installed on the frame 1 at intervals along the length direction of the mounting bracket 2. The two elastic members 64 are located on the side of the mounting bracket 2 away from the eccentric wheel 62, and each elastic member 64 is arranged opposite to each eccentric wheel 62. The elastic member 64 drives the mounting bracket 2 to rotate towards the eccentric wheel 62.
[0038] In practical applications, by rotating the worm of the worm and worm gear reducer 63, the worm wheel of the worm and worm gear reducer 63 is driven to rotate, so as to drive the rotating shaft 61 to rotate, so that different positions of the eccentric wheels 62 at both ends of the rotating shaft 61 are in contact with the mounting bracket 2, so as to drive the mounting bracket 2 to rotate. Since the upper cutter 4 is installed on the tool holder 3 slidably connected to the mounting bracket 2, the position of the upper cutter 4 is adjusted, so as to adjust the gap between the upper cutter 4 and the lower cutter 5. Therefore, only by rotating the worm can the gap between the upper cutter 4 and the lower cutter 5 be adjusted, and the operation is simple and convenient, thus facilitating the adjustment of the gap between the upper cutter 4 and the lower cutter 5.
[0039] Moreover, the elastic member 64 drives the mounting bracket 2 to rotate towards the eccentric wheel 62, so that the mounting bracket 2 is stably limited between the elastic member 64 and the eccentric wheel 62, and the rotation of the mounting bracket 2 during the cutting of the plate is avoided as much as possible to ensure the stability of the cutting work. And under the action of the worm and worm gear reducer 63, the adjustment accuracy of the gap between the upper cutter 4 and the lower cutter 5 is high, thereby improving the cutting accuracy.
[0040] Refer to Figure 1 and Figure 3 In some embodiments, a dial 631 is provided on the side of the worm and worm gear reducer 63 away from the machine frame 1. Scale lines are provided on the dial 631 to represent the gap between the upper cutter 4 and the lower cutter 5. A pointer 632 is provided on the side of the dial 631 away from the machine frame 1. The rotating shaft 61 extends to the outside of the worm and worm gear reducer 63 and is fixedly connected to the pointer 632. In practical applications, the pointer 632 can rotate synchronously with the rotating shaft 61, so that the pointer 632 points to different positions on the dial 631, and the size of the gap between the upper cutter 4 and the lower cutter 5 can be judged through the scale lines, so as to facilitate the adjustment of the position of the upper cutter 4.
[0041] In some embodiments, a fastening bolt 633 is provided on the side of the pointer 632 away from the scale line. One end of the fastening bolt 633 passes through the pointer 632 and is threadedly connected to the rotating shaft 61, and the other end abuts against the pointer 632 to realize the detachable connection between the pointer 632 and the rotating shaft 61, so as to facilitate the installation and disassembly of the pointer 632. When debugging the plate shearing device, it is convenient to adjust the position of the pointer 632, so as to ensure that the pointer 632 points to the accurate position on the dial 631, and further ensure the accurate adjustment of the gap between the upper cutter 4 and the lower cutter 5.
[0042] In some embodiments, a hand wheel 634 is provided on the worm of the worm and worm gear reducer 63. The hand wheel 634 is used for the staff to apply force, so as to facilitate the rotation of the worm of the worm and worm gear reducer 63, and thus facilitate the adjustment of the gap between the upper cutter 4 and the lower cutter 5.
[0043] Refer to Figure 1 and Figure 2, in some embodiments, the adjustment assembly 6 further includes two bearings 65. The two bearings 65 are respectively sleeved and fixed on the two eccentric wheels 62, so that the bearings 65 abut against the mounting frame 2. When the rotating shaft 61 rotates, the bearings 65 replace the eccentric wheels 62 to contact and rotate with the mounting frame 2, so as to reduce the dry friction between the eccentric wheels 62 and the mounting frame 2, make the rotation of the rotating shaft 61 easier, and thus facilitate the adjustment of the gap between the upper cutter 4 and the lower cutter 5.
[0044] In some embodiments, the adjustment assembly 6 further includes two limit bolts 66. The two limit bolts 66 are respectively threadedly connected to the two inner sides of the frame 1 and abut against one side of the mounting frame 2 close to the rotating shaft 61, and the limit bolts 66 and the eccentric wheels 62 are arranged at intervals in the vertical direction, so that the lower ends of the limit bolts 66 close to the mounting frame 2 can further limit the rotation of the mounting frame 2 to ensure the stability of the cutting work.
[0045] Refer to Figure 2 and Figure 3 , in some embodiments, the adjustment assembly 6 further includes a mounting box 67. The mounting box 67 is fixedly connected to the frame 1 by bolts. The elastic member 64 is located in the mounting box 67, so that one end of the elastic member 64 elastically abuts against the mounting box 67, and the other end elastically abuts against the mounting frame 2. The elastic member 64 can be installed by putting the elastic member 64 into the mounting box 67 and then fixedly connecting the mounting box 67 to the frame 1, thus facilitating the installation of the elastic member 64.
[0046] The implementation principle of this embodiment is as follows: in practical applications, by rotating the worm of the worm and worm gear reducer 63, the worm wheel of the worm and worm gear reducer 63 is driven to rotate, so as to drive the rotating shaft 61 to rotate, so that different positions of the eccentric wheels 62 at both ends of the rotating shaft 61 abut against the mounting frame 2, so as to drive the mounting frame 2 to rotate. Since the upper cutter 4 is installed on the tool holder 3 slidably connected to the mounting frame 2, the position of the upper cutter 4 is adjusted, so as to adjust the gap between the upper cutter 4 and the lower cutter 5. Therefore, only by rotating the worm can the gap between the upper cutter 4 and the lower cutter 5 be adjusted, and the operation is simple and convenient, thus facilitating the adjustment of the gap between the upper cutter 4 and the lower cutter 5.
[0047] Moreover, the elastic member 64 drives the mounting frame 2 to rotate towards the eccentric wheel 62, so that the mounting frame 2 is stably limited between the elastic member 64 and the eccentric wheel 62, and the rotation of the mounting frame 2 during the cutting of the sheet is avoided as much as possible to ensure the stability of the cutting work. And under the action of the worm and worm gear reducer 63, the adjustment accuracy of the gap between the upper cutter 4 and the lower cutter 5 is high, thus improving the cutting accuracy.
[0048] The embodiment of the present application also discloses a slitting machine.
[0049] The slitting machine includes the shearing device described in the above embodiment.
[0050] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all 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.
