Stamping head replacing structure of stamping die
Technical Field
The invention relates to the field of replacement structures, in particular to a replacement structure of a stamping head of a stamping die.
Background
The stamping is a forming processing method for applying external force to plates, strips, pipes, profiles and the like by a press and a die to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) with required shapes and sizes, the stamping and the forging belong to the same plastic processing (or called pressure processing), the stamping is called forging and pressing, the stamped blanks are mainly hot-rolled and cold-rolled steel plates and steel strips, 60-70 percent of the steel products in the world are plates, most of the plates are stamped to be manufactured into finished products, automobile bodies, chassis, oil tanks, radiator sheets, steam drums of boilers, shells of containers, iron core silicon steel sheets of motors and electric appliances and the like are stamped, and a large number of stamped parts are also arranged in products such as instruments, household appliances, bicycles, office machines, domestic utensils and the like, the stamping processing is that the plates are directly subjected to deformation force in the die and are deformed by the power of conventional or special stamping equipment, the sheet metal, the mould and the equipment are three elements of stamping processing, the sheet metal is divided into hot stamping and cold stamping according to the stamping processing temperature, the former is suitable for the sheet metal processing with high deformation resistance and poor plasticity, the latter is carried out at room temperature, the sheet metal is a stamping method commonly used for thin plates, the sheet metal is one of the main methods of metal plastic processing (or pressure processing), and the sheet metal is also affiliated to the material forming engineering technology, wherein the mounting structure of the stamping head plays a certain role in mounting and using in stamping, the sheet metal can be convenient for mounting and using of various stamping heads, has better fixing effect, has lower production cost and is widely applied to the field of stamping moulds;
however, the existing stamping die stamping head replacement structure has certain disadvantages when in use, the long-term impact of the stamping head during use can not quickly dissipate a large amount of heat, so that the stamping head can not be damaged, the stamping head fixing rod of the stamping head can not ensure the tight contact with the top of the mounting groove when the stamping head fixing rod and the top of the mounting groove are mounted, the stamping head can be damaged easily due to the impact force caused by the existence of a gap, and the mounting structure body at the current stage can not be used for mounting and dismounting.
