Description

Stamping die protection device

Technical Field

The utility model relates to a punching press technical field particularly, relates to a stamping die protection device.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. At present, most dies are formed by stamping, which is a forming processing method for obtaining a workpiece (stamping part) with a required shape and size by applying external force to a plate, a strip, a pipe, a section and the like by a press and a die to cause plastic deformation or separation. 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 lot of stamping parts in the products such as instruments, household appliances, bicycles, office machines, living utensils, etc., the stamping process is a production technology which makes the sheet material directly receive the deformation force and deform in the die by the power of the conventional or special stamping equipment, thereby obtaining the product parts with certain shape, size and performance. 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. When the stamping die is used, the stamping head and a workpiece are inevitably collided incorrectly, so that the stamping effect of the workpiece is influenced, the stamping head is damaged to a certain extent, and the stamping die is protected to a great extent.
