Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a metal sheet corner bending device for hardware processing. Background Art

[0002] Hardware processing is the process of processing raw materials into various parts according to customer drawings or samples using lathes, milling machines, drilling machines, polishing machines and other machines. When processing metal sheets, it is usually necessary to perform corner processing according to the needs of subsequent parts assembly and other operations.

[0003] After searching, for example, a Chinese patent document discloses a corner bending device for hardware processing [application number: CN202222322021.8]. This corner bending device for hardware processing includes a bottom plate.

[0004] The device disclosed in this patent can facilitate the staff to quickly disassemble and replace the corner blocks and triangular pressure blocks in preparation for the subsequent use of metal sheets for corner folding. However, the device has certain limitations in the way that it only uses the corner blocks and triangular pressure blocks to fold the metal sheets. That is, the corner blocks and triangular pressure blocks are difficult to fold the metal sheets into other shapes, and the flexibility during use is relatively poor. In addition, when the staff replaces the corner blocks, they need to move the triangular blocks while moving the two first toggle pieces. This process is inconvenient for one person to operate alone. When installing the triangular pressure block later, the staff also needs to align the triangular pressure block with the first convex slide rail while moving the two first toggle pieces. This process is also inconvenient for one person to operate alone. Utility Model Content

[0027] The positioning mechanism 15 includes an arc plate 151, a positioning plate 152, a handle 153 and a tension spring 154. The surface of the arc plate 151 is fixedly connected to the inner wall of the slot.

The surface of the positioning plate 152 contacts the inner wall of the slot 8, and the bottom of the positioning plate 152 contacts the top of the base 6. When the surface of the positioning plate 152 contacts the inner wall of the slot 8, the position of the positioning plate 152 is limited under the action of the elastic force of the tension spring 154, and the position of the arc plate 151 is limited accordingly, thereby limiting the position of the limiting mechanism 16.

[0028] The limiting mechanism 16 includes a transverse plate 161 and a limiting plate 162. The surface of the transverse plate 161 is fixedly connected to the surface of the connecting plate 14.

[0029] The reset mechanism 18 includes a slide bar 181, a reset plate 182 and a tension spring 183.

One end of the piston rod of the electric push rod 4 is in contact with the surface of the thin plate 20. When the piston rod of the electric push rod 4 pushes the corresponding thin plate 20, the triangular pressure block 22 or the arc pressure block 23 moves accordingly to perform angle processing on the metal sheet. Thereafter, under the action of the elastic force of the tension spring 183, the triangular pressure block 22 or the arc pressure block 23 can move toward the direction of the electric push rod 4 for subsequent use.

[0030] Working principle: When the device is in use, the staff can place the metal sheet on the surface of the triangular angle plate 12 or the arc angle plate 13 according to the shape of the metal sheet to be angled, and then the staff can rotate the adjustment disk, and the worm 53 drives the worm wheel 52 to rotate, which can drive the turntable 2 to rotate through the rotating shaft 51, so as to adjust the direction of the electric push rod 4. After that, the staff starts the electric push rod 4, and the piston rod of the electric push rod 4 moves to push the corresponding thin plate 20. At this time, the triangular pressure block 22 or the arc pressure block 23 moves to squeeze the metal sheet, so as to perform angle processing on the metal sheet;

[0031] When the triangular pressing block 22 or the arc-shaped pressing block 23 is damaged, the staff can directly pull the corresponding thin plate 20 upward to disassemble the damaged triangular pressing block 22 or the arc-shaped pressing block 23, so as to replace the damaged triangular pressing block 22 or the arc-shaped pressing block 23 for subsequent use;

[0032] When the triangular corner plate 12 or the arc-shaped corner plate 13 is damaged, the staff can pull the limiting mechanism 16 while lifting the corresponding handle 153. At this time, the positioning plate 152 rotates under the force, and the tension spring 154 stretches under the force. Based on this, the staff can horizontally dismantle the limiting mechanism 16. After that, the staff can dismantle and replace the corresponding triangular corner plate 12 or arc-shaped corner plate 13 through the vertical plate 10. This process is relatively simple and can be operated by one person.
