[0003] In the process of sheet metal parts processing, the bending machine mold is mainly placed on the punching machine, and then the metal sheet is placed on the bending mold to bend the metal sheet. During the bending process, the gap between the upper and lower dies The force is applied to the sheet metal to cause plastic deformation of the sheet metal. During processing, different upper and lower dies should be selected according to the shape of the sheet metal. When the sheet metal is more complicated, the shape of the bend is also relatively Complicated, at this time, it is necessary to frequently replace the upper mold and the lower mold, and the replacement process is time-consuming and laborious; and during the processing, the workpiece will generate heat after plastic deformation, so let go of the workpiece at this time, and the workpiece The rebound performance is the strongest, which will reduce the precision of the finished sheet metal parts

The invention relates to the field of machining, and particularly discloses a method for stamping sheet metal parts. A machining device is used for bending a machined piece. Conversion of a lower die can be achieved by means of rotation in the whole device, the process of dismounting and mounting the die continuously is omitted, and machining efficiency is effectively improved. Moreover, water in a limiting rod can quickly take away heat generated by the lower die and the machined piece in the machining process, the machined piece can be cooled and shaped quickly, rebound resilience of the machined piece is lowered, and machining precision is improved. Meanwhile, the limiting rod and a glass reinforced plastic pipe in a first through hole can reflect light generated by a laser generator, the water can also achieve total reflection of the light, and therefore optical energy can be gathered onto a glass reinforced plastic plate in the first through hole, a positioning light spot of the machined piece is formed, and the machining precision is improved. According to the scheme, the dismounting and mounting steps of the lower die can be simplified, and the machining efficiency is improved.
Description
Technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a stamping and bending method for sheet metal parts. Background technique [0002] Sheet metal parts have the characteristics of light weight, high strength, low cost, and good mass production performance. They are widely used in the fields of electronics, communications, automotive industry, and medical equipment. Especially in computer cases, mobile phones, and MP3, plate-shaped metal is an indispensable part. As the application of sheet metal parts becomes more and more extensive, the demand for sheet metal parts is also increasing, and the requirements for machining accuracy are also getting higher and higher. [0003] In the process of sheet metal parts processing, it is mainly to place the bending machine mold on the punching machine, and then place the sheet metal parts on the bending mold to bend the sheet metal parts. During the bending process, between the upp...
