Pre-buried groove channel rivet rod riveting device

Abstract

The invention discloses a pre-buried groove channel rivet rod riveting device which comprises a pressing connection structure; the pressing connection structure comprises an upper die, a lower die anda base; a holding mechanism is arranged between the upper die and the lower die and comprises a supporting plate; a lower die groove is arranged at the middle part of the supporting plate; the holding mechanism is arranged on the two sides of the supporting plate; the lower end of the lower die is fixed on the base; the upper end of the lower die is arranged in the lower die groove and can slideup and down relative to the lower die groove; the base is provided with a plurality of guide holes; and a plurality of guide holes which are matched with the guide holes respectively are arranged on the lower end surface of the supporting plate and are charged into the guide holes respectively. By adopting the pre-buried groove channel rivet rod riveting device provided by the invention, when a rivet rod is riveted, a pre-buried groove channel needs to be put on the lower die only, the rivet rod after being heated is put in the holding mechanism, the upper die moves downward through holding ofthe holding mechanism, and the rivet rod is riveted to the groove channel, so that operation is convenient, and riveting efficiency is high.

Description

technical field [0001] The patent of the present invention relates to a pre-buried channel riveting equipment, especially a riveting rod riveting device. Background technique [0002] Pre-buried channels first originated in Europe, mainly used in nuclear power projects, and then gradually extended to civil projects, such as shield plates for subway tunnels and underground comprehensive pipe galleries. At present, in developed countries, most of the subway construction adopts pre-buried The technical solution of the buried channel. In recent years, the construction scheme of pre-buried channels has gradually been promoted in China, especially in the current subway construction, the use of pre-buried channels has gradually begun to increase, such as Shenzhen Metro Line 9, Shijiazhuang Metro Line 2 Lanzhou Metro Line 1, etc. [0003] Compared with the traditional on-site rebar planting, the pre-embedded channel has more advantages, which can effectively reduce the labor inten...

AI Technical Summary

Problems solved by technology

[0004] At present, the production of pre-buried channels mostly adopts hot-rolled channels, and the back riveting or welding rivet rods. Welding is gradually replaced by riveting due to its low processing efficiency and high requirements for workers' operating skills.

The method of riveting also has many problems at present, such as slow speed and looseness after riveting
