Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, and in particular to a plate positioning and cutting device with high-precision arc adjustment of a cutter head and an adjustment method. Background Art

[0002] A circular cutter is a tool or device used to cut circular materials. It usually consists of a rotating cutter and a fixed workbench. When the circular material is placed on the workbench, the cutter rotates along a predetermined path and cuts the desired circular shape. Some metal sheets require related equipment during processing to cut square metal sheets into circular metal sheets.

[0003] Some current circular cutting machines have the following disadvantages in the process of cutting out circular metal sheets: 1. Since the metal sheet being cut is relatively thin, it needs to be supported, but the support surface of the circular cutting machine for the metal sheet is not adjustable. If the designed support is relatively large, the cutter cannot contact the small-sized metal sheet after it is placed. If the designed support surface is relatively small, the edge of the larger raw material is prone to drooping and warping downward, thereby affecting the cutting process. Therefore, it is necessary to design a cutting device that can adjust the support surface; 2. During the cutting process, the cutting knife cuts a circular arc on the surface of the square metal sheet to form a circular 3. The cut scraps of the circular metal sheet are in strip shape, and the scraps will rotate or accumulate with the plate, which can easily hinder cutting and affect the accuracy. However, in order to prevent the scraps from rotating continuously with the plate, the staff needs to use pliers to cut them at the starting position of the cut of the cutting knife, and then continue to pull the scraps to prevent the scraps from rotating or accumulating with the plate. This method is too dangerous. The staff's hands are close to the machine, and the scraps are sharp, which can cut the gloves and cause scratches, posing a safety hazard; ③. The circular metal sheet needs to be polished on the side after cutting. The staff holds the grinding wheel and polishes it up and down, which is inefficient. Summary of the invention

[0046] The support and adjustment mechanism 7 includes a bolt vertical plate 71, which is connected to the top of the truncated table 2. The number of the vertical plates 71 is several and they are distributed in a circular array with the center of the truncated table 2 as the center of the circle, and the vertical plates 71 are designed in groups of two.

The rotating sleeve 78 is connected to the first screw 72 through a bevel gear transmission. The rotating sleeve 78 drives the first screw 72 to rotate in the manner of a large bevel gear driving a small bevel gear. The rotating column 5 passes through the rotating sleeve 78 and is rotatably connected to its inner wall through a bearing, so that the rotating column 5 will not affect the rotating sleeve 78 during the rotation process. When working, the first motor 79 is first turned on. The output shaft of the first motor 79 drives the rotating sleeve 78 to rotate through a belt. The rotating sleeve 78 drives the first screw 72 to rotate through the bevel gear. At this time, the first screw 72 drives the first threaded sleeve 73 on its surface to move in the horizontal direction. Multiple first screws 72 move synchronously. The threaded sleeve 73 synchronously moves away from the center of the disc 3, and the first threaded sleeve 73 drives the upper vertical rod 76 and the support wheel 77 to move, and synchronously adjusts the distance between multiple support wheels 77 and the center of the lower clamping plate 6 to achieve the adjustment of the support position to adapt to the cutting requirements of metal sheets with different radii. When the horizontal distance between the support wheel 77 and the center of the lower clamping plate 6 is slightly smaller than the diameter of the circular metal sheet after cutting, the first motor 79 is stopped, and the square metal sheet to be circularly cut is placed on the top surface of the lower clamping plate 6, and the top surface of the support wheel 77 is flush with the top surface of the lower clamping plate 6. At this time, the support wheel 77 contacts the bottom of the metal sheet to achieve support for the edge of the circular cutting line.

[0047] The second adjustment mechanism 15 includes a support plate 151, a second screw rod 152, a movable seat 153, a connecting rod 154 and a second threaded sleeve 155.

The two screws 152 rotate synchronously, and the second threaded sleeve 155 starts to move. The second threaded sleeve 155 drives the upper moving seat 153 to move in the horizontal direction. Since the rotation direction of the second screw 152 is the same as the rotation direction of the corresponding first screw 72, and the pitch of the two is also the same, the moving seat 153 moves with the support wheel 77. When the support wheel 77 moves away from the center of the lower clamping plate 6, the moving seat 153 also moves away from the center of the lower clamping plate 6. If the support wheel 77 approaches the center of the lower clamping plate 6 during the adjustment process, the moving seat 153 also follows the downward clamping. The center of the plate 6 is close to the movable seat 153, and the cutting mechanism 17 and the clamping mechanism 18 arranged above it are moved together for synchronous adjustment; the bottom of the movable seat 153 is also bolted with a lower support plate 156, and the surface of the lower support plate 156 is rotatably connected to the second running wheel 157.
