Description

Technical Field

[0001] The utility model relates to the technical field of dustproof rubber sleeve punching processing, in particular to a punching device for subsequent processing of dustproof rubber sleeves. Background Art

[0002] Dustproof rubber sleeves are accessories used to seal and protect various devices, connectors, cables, etc. from external environmental damage such as dust, dirt and liquids. They are widely used in various mechanical products, electronic equipment, instruments and meters and other fields.

[0003] The molding steps of dust-proof rubber sleeves mainly include preparing the mold, loading the rubber, high-temperature vulcanization, removing the product and post-processing. The molding is done by injecting the rubber into the mold cavity through the runner. The injection holes and the lifting rod system ensure that the rubber is evenly distributed and fills all the mold cavities. Vulcanization treatment is carried out under high temperature and high pressure conditions to make the rubber material chemically cross-linked to form a strong and elastic network structure. After vulcanization is completed, the mold opening ejector is used to lift the upper mold and the middle mold to automatically separate the mold. When the mold is fully opened, the formed dust-proof rubber sleeve is taken out.

[0004] During the subsequent processing of the dustproof rubber sleeve, holes are punched through a punching device. Punching can effectively increase the surface area of ​​the rubber sleeve, thereby accelerating the dissipation of heat and avoiding aging or deformation of the material due to overheating. Punching can keep the internal and external air pressure balanced, avoiding the internal and external air pressure difference in the working environment of the dustproof rubber sleeve. The uneven air pressure causes deformation or damage to the rubber sleeve. Punching makes the rubber sleeve more adaptable to these changes and maintains stability and reliability.

[0005] Compared with flat dust-proof rubber sleeves, punching is more convenient. Vertical punching can be performed using punching equipment. For cylindrical rubber sleeves, since the rubber sleeves have a certain degree of softness and toughness, direct punching is prone to deformation due to the lack of support during the punching process, resulting in errors in punching and a reduced product qualification rate. Utility Model Content

[0015] As a preferred solution of the present invention, the bottom of the fixed rod is connected to an electric telescopic rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In response to the problems raised in the background technology, the present application supports and positions the dust-proof rubber sleeve that needs to be punched by using a punching support and positioning device, and places the dust-proof rubber sleeve between multiple positioning support blocks and a punching positioning ring.
