Abstract

The invention discloses a design method of a novel punching die structure and aims to overcome the defects that ZP punching dies are poor in guidance, IPT punching dies are difficult to machine and high in material consumption and the like. The design method includes structural and size design of a punching die. The punching die structurally comprises a middle die, an upper punching rod and a lower punching rod and is characterized in that the diameters of the bodies of the upper punching rod and the lower punching rod and the diameter of a punching tail are all phi 22mm or phi 25.25mm, the overall length of the punching rods is 133.35mm, the punching tail is of the structure of the ZP type punching die or the IPTB type punching die, the middle die is the IPTB or IPTD type standard middle die. The novel punching die structure mainly applies to rotary type tablet machines.

Description

technical field [0001] The invention relates to a die structure, in particular to a design method for a die structure on a tablet press in pharmaceutical machinery. Background technique [0002] In my country's pharmaceutical, chemical, food and other industries, solid particles with certain effects are often made into tablets, and the machine that makes tablets is called a tablet press. The mold that directly compresses the powdery materials into shape on the tablet press It is called a punching die, and the punching die is composed of an upper punch, a middle die, and a lower punch. At present, there are domestic standard ZP punching dies on the tablet press in the market, and international standards include IPTB, IPTD, and IPTBB punching types. The total length of the ZP punch is 115mm, of which the length of the punch body is 76.5mm, the diameter of the punch body is Φ22mm, the diameter of the middle die is Φ26mm, and the maximum outer diameter of the punch tail is Φ22mm...
