Structure and Principle of Simple Die, Continuous Die and Compound Die
Blanking die according to the degree of process combination can be divided into: simple blanking die, continuous blanking die, composite blanking die.
1. blanking dies can be divided into simple blanking dies, continuous blanking dies and composite blanking dies according to the degree of process combination.
(I) simple punching die is open die
1. Definition: It refers to a process in which only punching or blanking is completed in one blanking.
2. Simple punching die can be divided:
(1) The unguided single-process mold is characterized by simple structure, light weight, small size, easy mold manufacturing and low cost. However, the use of die installation trouble, low die life, punching parts of poor precision, the operation is not safe.
The unguided simple die is suitable for blanking parts with low precision requirements, simple shape, small batch or trial production.
(2) The guide plate type simple punching die has high precision, long service life, installation frame and safe operation,. But manufacturing is more complicated. It is generally suitable for workpieces with simple shapes and small sizes.
(3) The guide pillar type simple punching die is the most widely used punching die and is suitable for mass production because the die is accurate and reliable, which can ensure the uniformity of the blanking gap, the high precision of the blanking workpiece, the long service life of the die and the convenient installation and use on the punching machine.
(II) continuous punching die
1. Definition of continuous blanking die: according to a certain sequence of procedures, the blanking die, also known as the die-feeding or step-jumping die, is used to complete punching and blanking at different positions of the die.
2. The positioning principle of continuous blanking die can be divided into: guiding pin positioning principle and side blade spacing principle
(III) compound punching die
1. Definition of composite punching die: in one stroke of the slider of the part bed, the punching die of the upper process of inner hole and outer shape is completed at the same station of the punching die at the same time.
2. The composite punching die can be divided into: formal composite die and inverted composite die according to the structure.
2. we look at the comparison table of these three molds
Unguided single process die
The upper die part of the punch is composed of a die and a punch, and is installed on the punch slider through the die handle. The lower mold part consists of a discharge plate, a guide rule, and a guide rule,. Concave die, lower die base, positioning plate, through the lower die base installed on the punch workbench. The upper die and the lower die have no direct guiding relationship and are guided by the punch guide rail.
