Simple perforating device for outer rubber layer of automobile air conditioner rubber tube

Abstract

The invention discloses a simple perforating device for an outer rubber layer of an automobile air conditioner rubber tube. The simple perforating device comprises a pinwheel (1), a beam slab (2), a guide rod (3), a spring (4), a bearing plate (5) and a gasket block (6). In the invention, a technical scheme that a rubber tube is introduced to pass through a pore passage enclosed by outer edges offour pinwheels of which central axes are orthogonal on the same plane and an inserting needle on the pinwheel rim punctures the outer rubber layer of the rubber tube for rolling perforation is adopted to overcome the shortcomings of complicated structure, complexity of debugging, inconvenience of operation, difficulty of maintenance and the like in the prior art. The simple perforating device forthe outer rubber layer of the automobile air conditioner rubber tube enables the perforating device to achieve the aims of simple structure, convenience of operation and simplicity of debugging and maintenance by the way of the pinwheel rolling and puncturing perforation.

Description

technical field [0001] The invention relates to a punching device in the production process of the rubber hose of an automobile air conditioner, specifically refers to a device for the outer rubber layer of the rubber hose of an automobile air conditioner used for punching vent holes in the outer rubber layer of the rubber hose during the process of processing and forming the rubber hose of the automobile air conditioner Simple punching device. Background technique [0002] Automobile air-conditioning rubber hose is made of composite inner and outer rubber layers. The inner rubber layer is heat-resistant, cold-resistant, medium leakage-resistant, and medium-swelling resistant. The outer rubber layer is resistant to high and low temperature, ozone aging, compression, tensile, and Wear resistance and anti-vibration ensure the overall mechanical strength and performance of the rubber hose; although the penetration resistance technology of the inner rubber layer is improving day...

AI Technical Summary

Problems solved by technology

[0003] The outer rubber layer punching machine of the prior art is an electromechanical integration equipment, which relies on imports from Japan, Europe and the United States. Its structure is complicated, the debugging is cumbersome, and the operation is inconvenient. The wearing parts must be imported with original packaging, which makes maintenance difficult; therefore, the prior art has structural Problems and deficiencies of complexity, cumbersome debugging, inconvenient operation, and difficult maintenance
