拉延模设计（Drawing die design） The second chapter is the design process of drawing die structure Section 2.1 technical requirements Each project will sign the technical agreement with customers (or other similar documents), technical agreement contained in the relevant information on all customer mold requirements, should carefully read the technical agreement before the start of each project. After receiving the production tasks, should first check method, understand the relevant information, including a name, product material, material thickness, blank size, production line and machine used in this order, the height of the closed mold etc.. According to the mechanical properties of material and material thickness from the technology agreement (or other documents signed with customers or their own design standards - first customer requirements based on whether the search) mold using soil block structure and mold body and soil block material, if the material is used to block forgings for casting soil structure, overall structure. The production line is divided into manual production line and automatic production line, automatic production line is divided into ordinary and high speed automatic line line, automatic line mould to design the corresponding induction device is an induction switch, a DC and AC induction switch points, depending on the production line set. Manual production line, process components in two machine tools between the transfer is done by manual, and automatic production line can be robot or manipulator to complete. The most essential difference between high-speed line and common automatic line is in the speed of production. Usually, the drawing die arrangements in the production line of the first machine tool production (some require blanking products, the machine is not) a single action and double action points according to different production line, the corresponding mold structure also corresponds to the single structure and the structure of doub
