Description

Adjustable punch press waist hole mould

Technical Field

The invention relates to the technical field of machining equipment of mechanical punches, in particular to an adjustable punch waist hole die.

Background

The steel die punching is a production process for processing hole positions on a plate by utilizing a male die and a female die which are made of tool steel, and shearing force is applied to the plate at the middle position between the male die and the female die according to the relative movement between the male die and the female die so as to complete the punching operation on the plate, wherein a waist hole is a common hole pattern in the field of machining and is mainly processed on a punch press.

At present, the existing waist-hole blanking die is divided into two forms: one is a die capable of only performing one-to-one blanking, that is, a punching female die of one specification can only punch a hole pattern of one specification, and female dies of different specifications are required to be prepared when waist holes of different sizes are required to be punched, but the female dies are relatively thick and heavy in manufacturing due to the fact that the female dies need to bear larger impact load, and further the manufacturing cost of waist hole dies of different specifications is increased seriously; the second is a sectional type waist hole blanking die, although the length of the waist hole can be adjusted by moving towards two sides, the middle position of the female die can have a larger gap after adjustment, so that the female die cannot support a workpiece, the waist hole at the position can be sunken in the process of pressing down by the male die, and meanwhile, due to the fact that the effect of supporting and extruding is lost, burrs at the position of the waist hole are more, and the quality of the punched waist hole of the workpiece is seriously influenced.
