A diameter reducing device for automatic oiling operation

Abstract

The invention discloses a portal reduction device for an automatic oil coating process. The portal reduction device comprises a portal reduction mechanism and an oil coating mechanism. The portal reduction mechanism comprises a portal reduction base and a portal reduction pressure cylinder fixed relatively to the portal reduction base. A retractable operation end at the bottom of the portal reduction pressure cylinder is provided with a portal reduction pressure head. The upper end of the portal reduction base is provided with a portal reduction Half-type part. The portal reduction Half-type part is located below the portal reduction pressure head and comprises a cylindrical Half-type sleeve and a cylindrical Half-type assembly arranged in the Half-type sleeve. The cylindrical Half-type assembly comprises multiple arc-shaped Half-type blocks arranged in a central symmetry way. The oil coating mechanism comprises an outer sleeve oil coating pipe arranged on the portal reduction pressure head and an inner sleeve oil coating pipe arranged on the portal reduction base. An oil outlet of the outer sleeve oil coating pipe is located above the cylindrical Half-type assembly. An oil outlet of the inner sleeve oil coating pipe is provided with a fuel injector. The portal reduction device realizes simultaneous automatic portal reduction and anti-rust oil coating and has the advantages of easy control of operation quality and high labor efficiency.

Description

technical field [0001] The invention relates to a diameter reducing device for automatic oiling operation, which belongs to the technical field of production and processing equipment for auto parts. Background technique [0002] The rubber material itself has the advantages of light weight, impact resistance and easy absorption of high-frequency vibrations. With the improvement of rubber and metal bonding technology, metal and rubber assemblies are widely used in support components such as automobile suspensions. The combination of metal and rubber is usually formed by heating and vulcanizing. During the vulcanization process, there is a certain heat shrinkage due to heating. After the vulcanization is completed, there is a gap between the rubber layers when it cools down, and the tensile strength is not enough. After the vulcanization is completed, it is necessary to reduce the diameter of the metal and rubber assembly and apply prestress to make the rubber arrangement dens...

Problems solved by technology

[0003] The diameter reduction process of the metal and rubber assembly is carried out on the diameter reduction device. In the prior art, it is necessary to manually apply anti-rust oil on the inner and outer surfaces of the metal and rubber assembly while performing the diameter reduction operation. The operation is not only low in labor efficiency, but also difficult to guarantee the quality of the operation. Uneven application of anti-rust oil often leads to rusting of metal and rubber assemblies and a decrease in service life.
