According to the structure, the stamping die can be divided into three categories: single engineering mold, composite mold and continuous mold. The first two categories require more manpower than economic benefits, and the continuous model can be mass-produced with high efficiency. Similarly, design a set of high-speed precision continuous die, a. Introduction Pressing die can be divided into three categories: single engineering die, composite die and continuous die. The first two categories require more manpower than economic benefits, and the continuous model can be mass-produced with high efficiency. Similarly, design a set of high-speed precision continuous die, but also for the products you produce (including all products processed by stamping, Foxconn Group mainly has terminals, computer casings and connectors for connectors and current mobile phone parts, etc. Wait). To design continuous die, attention should be paid to the spacing between the modules, the machining accuracy of the parts, the accuracy of the assembly, the accuracy of the matching and the interference problem, so as to achieve the purpose of mass production of continuous mode automation.
2. The concept of unitized design The overall structure of the stamping die can be divided into two parts: (1). Common part (2). The part that changes according to the product. The common part can be standardized or standardized, and the part that changes according to the product is difficult to normalize.
III. Composition and specifications of the template
1. The composition of the template
The composition of the stamping die will vary depending on the type and composition of the die, and there are two types of configurations: the configuration of the configuration and the configuration of the reverse configuration. The former is the most commonly used construction, and the latter is mainly used for extension forming dies or with special dies.
The main tasks involved include:
(1) Digital drawing--converting 3D products and mold models into 2D engineering drawings used in conventional processing;
(2) Digital design of the mold--based on the product model and design intent, establish the relevant 3D solid model of the mold;
(3) Digital analysis and simulation of the mold--structural analysis, thermal analysis, fatigue analysis and motion analysis of the mold according to the product forming process conditions;
(4) Simulation of product forming process - injection molding, stamping;
(5) Customized to fit the company's mold design standard parts and standard design process;
(6) Mold production management.
2. Specifications of the mold
(1). Mold size and locking screws
The size of the template should be larger than the work area and the standard template size should be selected. The position of the template locking screw is related to the type of mold and the size of the template. Among them, the single engineering mold is most often used in the four corners with the locking screws, and the most standard working area can be widely used. Long molds and continuous molds are most often placed in the four corners and intermediate positions using locking screws.
(2). Thickness of the template
The thickness selection of the template has an absolute relationship with the structure of the mold, the type of stamping, the processing force of the press, and the precision of the press. It is difficult to determine the thickness of the mold according to theoretical calculations. Generally, it is obtained by experience. The thickness of the template used for design should be as small as possible, and the mold height and clamping height should be standardized to facilitate procurement and inventory management.
