Design method for development size of novel extruded die plate

Abstract

The invention discloses a design method for the development size of a novel extruded die plate. The design method comprises the two main steps of (1), determining the width of the opening plate of a die plate, wherein the width of the opening plate comprises a shoulder width and a full width; (2) determining the thickness of the opening plate of the die plate, wherein when the thickness of the opening plate of the die plate is determined, on the basis of the determined width of the opening plate, glue types in different extruding machines, preform die of different sizes, and expansion rate inthe die plate of different shapes are researched, a computational formula of the expansion rate of rubber materials and the development size of the die plate is formulated, according to the formula obtained, the design size of the die plate with high precision can be obtained, and the qualified rate of one-time opening plate of the die plate is greatly improved; further, the mouth type developer does not need to perform design and development of the size of the die plate by virtue of empirical values, the culture period of mouth type workers is greatly reduced, the production cost of enterprises can be effectively reduced, the production efficiency can be improved, and the method has relatively high popularization and practical application values.

Description

technical field [0001] The invention belongs to the technical field of rubber tire component generation, and in particular relates to a method for designing the development size of a novel extrusion outlet pattern plate. Background technique [0002] Tires are an indispensable part of vehicles such as cars and trucks, and the performance of these vehicles is closely related to the characteristics of the tires. In the tire production process, each extruded half part needs to correspond to a separate die plate, so different die plates need to be designed. [0003] The traditional die plate design is to develop the die plate size according to the experience of the part design size. The die plate needs to go through at least 3 times of extrusion experiments. Only by welding and grinding can the qualified die size be obtained. The dimensional accuracy of the extruded half part plays an important role in the tire. Therefore, the design size and accuracy of the die plate play an ...
