Description

Robot for punching

Technical Field

The invention relates to the field of machining, in particular to a robot for stamping.

Background

The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. Stamping and forging are plastic working (or called pressure working), and are called forging and pressing. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. The body, chassis, oil tank, radiator sheet, boiler steam drum, shell of container, iron core silicon steel sheet of motor and electric appliance are all made by punching. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machines, and household utensils. The stamping process is a production technology for obtaining product parts with certain shape, size and performance by directly applying deformation force to a plate in a die by means of the power of conventional or special stamping equipment and deforming the plate. The plate, the die and the equipment are three elements of stamping processing. The hot stamping and the cold stamping are divided according to the stamping processing temperature. The former is suitable for processing sheet materials with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a common stamping method for thin sheets. It is one of the main methods of metal plastic working (or pressure working), and also belongs to the material forming engineering technology. The die used for stamping is called stamping die, and is called stamping die for short. A die is a special tool for batch processing of material (metallic or non-metallic) into the desired punches. The stamping die is of great importance in stamping, and batch stamping production is difficult to carry out without the stamping die meeting the requirements; without an advanced die, an advanced stamping process cannot be achieved. The three elements of the stamping process, the die, the stamping equipment and the stamping material form the stamping processing, and the stamping part can be obtained only by combining the three elements.
