Winding type rubber extrusion forming die and using method and application thereof

Abstract

The invention discloses a winding type rubber extrusion forming die and a using method and application thereof, and belongs to the technical field of rubber extrusion winding formation. By adoption ofthe winding type rubber extrusion forming die and the using method and application thereof, the problems that the shape and size of rubber extruded by existing winding type rubber roller coating equipment cannot ensure smooth and flat winding and attaching of rubber and high size precision are solved. By optimizing the design of the mold, the ratio of the chord length of the arc concave surface of the mold, the arc height of the arc concave surface and the right-angle side length of the transition surface of the mold is (55-65):(3-4):(1-2), so that the flow speed and thickness of rubber at the two ends of the mold can be increased, the stable size of extruded rubber is ensured, the surface of the rubber is smoothly formed, and the edges of the two ends of the rubber are ordered, and through arrangement of the arc concave surface, it is ensured that the left side and the right side of the rubber are centrally symmetrical, accordingly, the pitch range for winding and attaching is ensured, and it is also ensured that the size precision of rubber attaching can be flexibly controlled by adjusting the pitch when the rubber is wound and attached forward and reversely.

Description

technical field [0001] The invention belongs to the technical field of rubber extrusion winding molding, and in particular relates to a winding rubber extrusion molding die and its use method and application. Background technique [0002] With the rapid development of industries such as steel, paper and printing, the demand for rubber rollers is increasing, and the requirements for rubber rollers are getting higher and higher. How to improve efficiency and quality is a must for all rubber roller manufacturers. and solve the problem. The rubber roller wrapping equipment of winding method solves the problem that the rubber roller is extruded and wrapped on the automatic winding machine. Although this can improve the quality and output, but the current molding die is prone to extruded rubber shape, Quality issues such as size and appearance restrict the efficiency of rubber wrapping after extrusion. Therefore, in order to further improve the efficiency and quality, we need to...

Problems solved by technology

[0006] Aiming at the problem that the rubber extruded by the existing rubber roll wrapping equipment of the winding method cannot guarantee the smoothness of the rubber winding and bonding, the present invention provides a rubber extrusion molding die for the winding method and its use method and application. By optimizing the molding die The unique design can increase the flow speed and thickness of the rubber at both ends of the forming mold to ensure the stability of the extruded rubber size. When the rubber is used, the dimensional accuracy of the rubber bonding can be flexibly controlled by adjusting the pitch
