Description

Technical Field

[0001] The invention belongs to the technical field of bowl-hook type joint production equipment, and specifically relates to a bowl-hook type aluminum alloy joint production device. Background Art

[0002] The cup-hook scaffolding is a new type of scaffolding developed on the basis of absorbing the advanced joints and accessories technology of the same type of scaffolding abroad and combining with the actual situation in my country. The cup-hook scaffolding joint has a reasonable structure, simple manufacturing process, easy operation, and a wide range of use. It can fully meet the construction requirements of various buildings such as houses, bridges, tunnels, and water towers. The cup-hook scaffolding is composed of steel pipe uprights, cross bars, cup-hook joints, etc. The assembly form is flexible and the bracket spacing can be flexibly adjusted. The dimensions of each component are unified, and the erected scaffolding has the characteristics of standardization and standardization. The disassembly and assembly efficiency is high, the loose parts are not easy to lose, and the transportation is convenient. It can be transformed using fastener steel pipes, which greatly reduces the renewal cost.

[0003] As a core component, the bowl-hook joint is usually produced by casting technology. A snap-on connection part is provided inside the bowl of the bowl-hook joint. Due to its internal functional shape, the prior art usually uses a sand core as a mold to be manually filled and produced, and the sand core must be manually disassembled after molding. The sand core used becomes waste after production and cannot be recycled, which is not conducive to environmental protection, reduces production efficiency, and increases production costs. Moreover, the traditional sand core used as a casting mold core will affect the quality of the casting due to the tightness of the overall structure of the sand core, affect the thickness and uniformity of the fine grain area of ​​the casting surface at the clamping point, easily produce pores, and increase the defective rate.

[0004] If metal mold cores are used instead of sand cores for molding production, it is difficult to separate the product from the metal mold core after casting. Generally, manual multi-point knocking is used for demoulding, and the demoulding efficiency is low. Since the strength of the knocking process is difficult to control, the mold is easily damaged, affecting the quality of product molding and the service life of the mold.
