Embodiment Construction

[0042] In order to understand the above-mentioned purposes and advantages of the utility model more clearly, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings:

[0043] A method for developing dimension design of an extrusion outlet pattern, specifically comprising the following steps:

[0044] Step 1, determine the opening width of the mouth plate, and the opening width includes shoulder width and full width;

[0045] (1) Extrude the width of the extruded parts under the same specifications, the same rubber type, the same screw speed and different die widths to determine the optimal die width. The schematic diagram of the die width is as follows image 3 As shown, where the shoulder width is J, and the overall width is Q;

[0046] (2) Differentiate the type of machine, and analyze and design the details of the width and size of the mouth plate;

[0047] Such as Figure 4 As shown, the opening width o...

Abstract

The invention discloses a novel size design method for the development of a die plate, which includes (1) determining the opening width of the die plate, the opening width including the shoulder width and the full width; (2) determining the opening thickness of the die plate The first main step is to study the expansion rate of various rubber types in different extruders, different sizes of dies, and different shapes of dies based on the determined die width when determining the thickness of the die plate. And formulate the calculation formula of the expansion rate of the rubber material and the development size of the die plate, and the design size of the die plate with high precision can be obtained according to the obtained formula, which greatly improves the qualified rate of the first opening of the die plate; and the die developer It is no longer necessary to rely on experience to design and develop the size of the lip plate, which greatly reduces the training cycle of the lip shaper, can effectively reduce the production cost of the enterprise, improve production efficiency, and has high promotion and practical application value.

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 die 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 important role in the size ...
