Description

Stamping and fixing device for machining gantry shell

Technical Field

The utility model relates to a stamping equipment technical field specifically is a punching press fixing device of longmen shell processing.

Background

The gantry shell is a sheet metal part, is often used as a fixed shell of various mechanical devices, and has the characteristics of high strength, no edges and corners on the surface and the like, so that the gantry shell is widely applied. 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. But the following defects exist in the stamping process aiming at the gantry shell at present:
