[0002] In the sheet metal processing industry, stamping and bending are two common processes. Traditionally, companies need to purchase dedicated punch presses and bending machines to perform these two tasks, resulting in high equipment costs, large floor space requirements, and reduced production efficiency due to the need to transfer sheet metal between different machines. For example, Chinese patent CN201210330795.3 discloses a bending machine whose function is limited to bending sheet metal. Although some solutions attempt to perform simple punching at the bending station, most are fixed or temporary tooling, resulting in poor versatility, cumbersome assembly and disassembly, low positioning accuracy, and interference with the original function of the bending machine.

[0003] Therefore, there is an urgent need for a standardized stamping accessory that can be quickly and securely connected and separated from the bending machine without affecting the original operation of the bending machine, so as to complete multiple processes on one machine and reduce the overall processing cost of the factory.

[0007] In this utility model, a fixing block is fixedly installed on the side of the first assembly plate. The fixing block has a through hole. The first threaded sleeve passes through the through hole and a drive disc is fixed at its end. The fixing block has a rotating groove inside to accommodate the drive disc.

[0008] In this invention, a light rod is fixedly installed on both the upper template and the lower template, and a sliding sleeve is slidably connected to the outer side of the light rod. The end of the sliding sleeve is fixedly connected to the first assembly plate.

[0009] In this invention, a T-shaped slider is fixedly installed at the end of the second assembly plate, and a T-shaped groove adapted to the T-shaped slider is provided on the side of the first assembly plate, and the T-shaped slider is embedded in the T-shaped groove.

The assembly mechanism includes a first screw 5 fixedly connected to the upper template 2 and the lower template 3, and a first screw thread screwed to the outside of the first screw 5. The components include: a screw sleeve 6; a first assembly plate 7 rotatably connected to the first screw sleeve 6; a return spring 9 connected between the first assembly plate 7 and the second assembly plate 8; a second screw 10 fixedly connected to the first assembly plate 7; a second screw sleeve 11 screwed to the outside of the second screw 10; and an insert block 12 fixedly installed on the sides of the first assembly plate 7 and the second assembly plate 8; and a pressure plate mechanism, which is mounted on the bending machine 18 and includes a positioning plate 13 fixedly installed on the body of the bending machine 18 and a pressure rod 15 installed on the side of the positioning plate 13 by a wing bolt 14.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the side of the connecting plate 1 is provided with a slot adapted to the insert block 12, and the insert block 12 extends into the slot. A lower die base is fixedly installed above the lower template 3, and the surface of the lower die base is provided with a punch groove adapted to the stamping column 4. A fixing block is fixedly installed on the side of the first assembly plate 7. The fixing block is provided with a through hole, and the first threaded sleeve 6 passes through the through hole and its end is fixed with a driving disc. The fixing block is provided with a rotating groove to accommodate the driving disc, so that the first threaded sleeve 6 can rotate freely relative to the first assembly plate 7 but is axially limited.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, both the upper template 2 and the lower template 3 are fixedly mounted with a light rod 16. A sliding sleeve 17 is slidably connected to the outer side of the light rod 16. The end of the sliding sleeve 17 is fixedly connected to the first assembly plate 7. The arrangement of the light rod 16 and the sliding sleeve 17 ensures that the first assembly plate 7 moves smoothly. A T-shaped slider is fixedly mounted to the end of the second assembly plate 8. The side of the first assembly plate 7 is provided with a T-shaped groove that matches the T-shaped slider, and the T-shaped slider is embedded in the T-shaped groove.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the side of the second assembly plate 8 is provided with a through hole for the second screw 10 to pass through, and the second screw sleeve 11 abuts against the side of the second assembly plate 8. Positioning screw grooves are provided at intervals along the height direction of the positioning plate 13, and the end of the wing bolt 14 passes through the pressure rod 15 and is screwed into the positioning screw groove. A flexible pad is adhered to the side of the pressure rod 15 to avoid scratching the surface when pressing the plate.

[0021] Working process: First, the connecting plate 1 is fixedly connected to the convex template 19 and concave template 20 of the bending machine 18 respectively. When the sheet metal needs to be stamped, the second threaded sleeve 11 is rotated counterclockwise to move it away from the second assembly plate 8. Under the thrust of the return spring 9, the second assembly plate 8 is pushed to move horizontally. Then, the first threaded sleeve 6 is rotated counterclockwise to move the first assembly plate 7 horizontally. Subsequently, each insert 12 is roughly aligned with the slot on the connecting plate 1. The first threaded sleeve 6 is rotated clockwise to drive the first assembly plate 7 to move towards the connecting plate 1 until the end of the insert 12 enters the slot. Then, the second threaded sleeve 11 is rotated clockwise to press against the second assembly plate 8, overcoming the elasticity of the return spring 9, and pushing the insert 12 on the second assembly plate 8 further into the slot. Through the coordinated tightening of the first threaded sleeve 6 and the second threaded sleeve 11, all inserts 12 are finally made to form an interference or tight fit with the slot, thereby stamping. The components are rigidly assembled on the connecting plate 1 to complete the assembly of the upper template 2 and the lower template 3. Then, the sheet metal is placed on the lower die base of the lower template 3. According to the thickness of the sheet metal, the wing bolts 14 and the pressure rods 15 are installed in the positioning screw grooves at appropriate positions on the positioning plate 13. This allows the pressure rods 15 and the flexible pads to be pressed tightly onto the sheet metal, effectively preventing the sheet metal from shifting during the stamping process and further improving the processing quality. Then, the cylinder of the bending machine 18 is started to drive the convex template 19 downward, which can drive the upper template 2 and the stamping column 4 to complete the stamping of the sheet metal. When the sheet metal needs to be bent, the first screw sleeve 6 and the second screw sleeve 11 are rotated in the opposite direction to remove the upper template 2 and the lower template 3. The sheet metal is then placed on the concave template 20. Then, the cylinder of the bending machine 18 is started, and the convex template 19 presses the sheet metal downward to complete the bending of the sheet metal. The bending machine can then be used normally. The two processes do not affect each other, improving the overall utilization rate of the equipment.
