Embodiment Construction

[0030] Embodiments of the present invention will be described below with reference to the drawings.

[0031] figure 1 It shows the vulcanization molding apparatus 1 using the elastic crawler manufacturing method related to the first embodiment of the present invention, figure 2 The elastic crawler belt 2 which is a product manufactured by the vulcanization molding apparatus 1 is shown. in addition, figure 1 The left and right directions of the figure 1 same.

[0032] like figure 2 As shown, the elastic crawler 2 is an elastic crawler used in a crawler-type traveling device such as a combine harvester or a harvester, and has a crawler main body 3 formed of an elastic rubber material in a jointless shape, a steel rope buried in the crawler main body 3, and the like. The anti-expansion body 4, the driving protrusion 5 protruding from the inner peripheral side (lower side in the figure) of the crawler main body 3, and the flange 6 protruding from the outer peripheral side (...

Abstract

This invention provides a manufacturing method for elastic pedrails adhered tightly by sulfuration and a sulfuration molding device, which utilizes a metal mold separated into a heating region and a cooling region along the length of the pedrail to make one end at the un-sulfurated state or semi-sulfurated state and sulfurate it to a strip rubber, then forms an un-sulfurated or semi-sulfurated joint faces to be adhered to the other end of a strip rubber body at such state so as to integrate them to one body as a product and adheres said joint face to the other end of the strip rubber in sulfuration when the ambit line between the joint face and outside of the product is in the cooling region and away from the heating region.

Description

technical field [0001] The present invention relates to a method for manufacturing an elastic crawler mounted on various crawler-type traveling devices, etc., and a vulcanization molding device using the method. Background technique [0002] Conventionally, elastic crawlers, for example, are known as jointless elastic crawlers mounted on agricultural and forestry vehicles, construction vehicles, and the like. As a method of manufacturing this elastic crawler, for example, a manufacturing method called feed vulcanization described in Japanese Patent Laid-Open Publication No. 2002-120231 is known and is being put into practical use. [0003] Based on the manufacturing method of the feed-vulcanized elastic crawler, using a metal mold divided into a heating zone and a cooling zone in the belt length direction, one end of the belt length direction is unvulcanized or semi-vulcanized, and vulcanized into a belt-shaped rubber After that, the unvulcanized or semi-vulcanized joint su...
