Description

Nut stamping equipment

Technical Field

The invention relates to the technical field of nut stamping, in particular to nut stamping equipment.

Background

The nut is a nut, and is screwed together with a bolt or a screw rod to play a role in fastening, and one element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types according to different materials.

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 existing nut stamping equipment needs to manually place the nut below the stamping head in the stamping process, so that the operation is complex, and when manual operation is possibly caused, the stamping head presses the hand of an operator to cause injury.
