[0002] In the process of processing metal sheets, it is often necessary to process the metal sheets into a bent shape. Metal bending processing equipment is processing equipment that can automatically bend metal sheets. Under the pressure of the upper mold or lower mold of the bending processing equipment, the metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is free to bend. The strip plate is pressed vertically downward by the extrusion moving mold to cooperate with the forming mold to achieve bending and forming. However, the existing bending forming molds generally do not set limit components for the original metal sheet. When processing sheets of different sizes, it is often necessary to replace the mold again, which increases the labor intensity of workers and may cause jumping of materials during extrusion, endangering personal safety.

[0024] See also Figure 1-3 The utility model provides a technical solution: a sheet side bending die, including a lower template 1 and an upper template 2, a die seat 4 for cooperating with a stamping assembly 3 to extrude the sheet to be processed is fixedly arranged at the top of the lower template 1, a guide rod 5 is symmetrically arranged on the rear side of the top of the lower template 1, and slide grooves 6 are provided on both sides of the top of the die seat 4. Limit blocks 7 are staggeredly installed on both sides of the slide groove 6, and a positioning plate 8 is movably connected through the limit blocks 7. A die handle 9 is installed at the top of the upper template 2, and a guide sleeve 10 matching the size of the guide rod 5 is arranged at the bottom, and a stamping assembly 3 is arranged below the upper template 2.

[0025] In this embodiment, the stamping device as a whole is supported by the lower template 1, and the lower template 1 is slidably connected to the guide sleeve 10 correspondingly arranged at the bottom end of the upper template 2 through the symmetrically arranged guide rods 5. The cooperation between the guide rods 5 and the guide sleeves 10 can limit each other, ensuring that the stamping assembly 3 remains stable during the pressing process and reducing errors. When working, the sheet to be processed is first placed in the corresponding position of the die seat 4, and then the position of the positioning plate 8 in the slide groove 6 is slid and adjusted according to the length of the sheet to be processed so that it is engaged with the limit block 7 at the corresponding position to fix the sheet to avoid jumping. There is no need to replace the mold again, which saves time and effort and effectively reduces the labor intensity of workers.

[0026] like Figure 4-6 As shown, in this embodiment, limit blocks 7 are staggered on both sides of the slide groove 6, and positioning holes 11 matching the positions and sizes of the limit blocks 7 are set at the bottom of the T-shaped positioning plate 8, so that the present mold can adapt to the sheet materials to be processed with a larger range of length size variation. In actual applications, combined with the production conditions of the products themselves, such as when the sizes of the products produced are usually a few fixed values ​​with little change, limit blocks 7 and positioning holes 11 can be set on one side of the slide groove 6 and the positioning plate 8 to reduce the cost and difficulty of manufacturing the present mold.

[0027] In this embodiment, the limit block 7 is configured to have a hollow cavity, and staggered notches 12 are provided on both sides of the slide 6 for accommodating the limit block 7. One end of the return spring 13 is connected to the inside of the limit block 7 and the other end is connected to the notch 12 on the inner wall of the slide 6. At the same time, the two sides of the positioning hole 11 are configured to be inclined outward by 45 degrees. 0 ~60 0 The connection end of the limit block 7 is set to a semicircular arc shape. When processing longer sheets, the positioning plate 8 is slid outward in the slide groove 6 so that the connection end of the limit block 7 moves along the inclined surface 14 and gradually disengages from the positioning hole 11. After complete disengagement, the two side walls of the positioning plate 8 squeeze the limit blocks 7 on both sides of the slide groove 6 and shrink into the notch 12. Continuing to slide outward, the connection end of the limit block 7 will move along the new inclined surface 14 and gradually enter the next positioning hole 11, and so on until it is adjusted to a suitable position. Similarly, when processing shorter sheets, the positioning plate 8 is slid inward in the slide groove 6 until it is adjusted to a suitable position.

[0028] like Figure 1 As shown, in this embodiment, the stamping assembly 3 includes a mounting seat 301 and a stamping head 302. The connecting end of the mounting seat 301 is provided with a slot for accommodating the stamping head 302 and is fixedly connected to the upper template. The stamping head 302 is detachably connected to the slot of the mounting seat 301 through a fixing member 303. When the stamping head 302 is worn out after long-term use and does not meet the product processing accuracy requirements or is damaged by improper manual operation, a new stamping head 302 can be quickly replaced without scrapping and replacing the entire stamping assembly 3, which can effectively save materials and improve production efficiency.
