Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a sheet metal bending forming device. Background Technology

[0002] In machining, sheet metal bending is quite common. Currently, sheet metal bending is generally done using bending equipment. In existing technology, there are many structural forms of bending equipment, but they are generally quite complex, inconvenient to operate, and have high purchase costs. In addition, some structures lack positioning and limiting, resulting in longer forming accuracy.

[0003] Furthermore, due to the significant differences in the structure of workpieces, it is difficult to make universal bending equipment. Therefore, it is necessary to develop a forming device suitable for bending one's own workpieces. Utility Model Content

The rotating frame is rotatably connected to the arc-shaped end on its inner side, and its rotation center is concentric with the center of the arc-shaped end. The forming roller is rotatably connected inside the rotating frame and is located on the outer side of the arc-shaped end. Limiting and clamping components are respectively provided on both sides of the forming mold. The limiting and clamping components are used for limiting and clamping the workpiece.

[0006] Preferably, the limiting and pressing assembly includes a pressing and limiting plate and a pressing and locking assembly.

[0007] Preferably, at least one end of the upper and lower ends of the clamping and limiting plate is provided with a limiting flange to form an "L"-shaped limiting or a groove-shaped limiting. The clamping and locking assembly includes a clamping screw and a screw sleeve. The screw sleeve is disposed on the locking mounting bracket of the frame, and the clamping screw is rotatably engaged with it. The inner end of the clamping screw is rotatably connected to the outer side of the clamping and limiting plate.

[0008] Preferably, the forming mold is provided with positioning elements on both sides, which are used for limiting and positioning the workpiece in the length direction.

[0009] Preferably, the positioning element is slidably connected to the molding die and slides back and forth along the length of the molding die.

[0010] Preferably, the molding die has a sliding limiting elongated hole along its length, and the positioning component includes two positioning blocks and a locking bolt connecting the two positioning blocks. The two positioning blocks are located on the inner and outer sides of the sliding limiting elongated hole and slide along it. The locking bolt is used to lock and fix the sliding.
