Abstract

The invention discloses a hose depoling method, in specific: after a hose model is molded, high-pressure medium is led to the contact surface between a model core and a hose; the high-pressure medium leads the hose to have radial expansion, and the model core is taken out after the hose and the model core mutually separate. A hose depoling device used for applying the method comprises a support device and an annular plug; wherein the support device is used for supporting the hose with the model core; one end of the annular plug is inserted into the contact surface between the model core and the hose; the annular plug can be used for leading the high-pressure medium to the contact surface between the model core and the hose; the high-pressure medium leads the hose to have radial expansion, and the model core is taken out after the hose and the model core mutually separate. By means of the characteristics of high-pressure air or high-pressure water, the method and the device can easily take out the hose with multiple corrugations and long length, thereby solving the problems of difficult depoling and depoling fail of the prior art. Furthermore, the device has the advantages of simple structure, high efficiency and low cost, etc.

Description

technical field [0001] The invention relates to the field of rubber hoses for automobiles, in particular to a method and a device for removing cores from rubber hoses. Background technique [0002] With the development of the automobile industry, rubber hoses of various calibers are installed on the air inlet and outlet systems of automobiles. When making such multi-corrugated, large-length, corrugated and long-length rubber hoses, it is extremely difficult for the forming core to come out. Traditional core removal generally adopts the following two methods: one is to make the corrugated section in the multi-corrugated core into a split structure, and withdraw the corrugated section separately during core removal to complete the core removal. The second is to make the large-length rubber hose into a two-section or multi-section structure, and then connect the steel pipe or plastic pipe through interpolation, and add clamps to fix and connect the multi-section rubber hose. ...
