Pipe fitting riveting machine

Abstract

The invention discloses a pipe fitting riveting machine, comprising a rack, a clamping mold for fixing the pipe fitting and a riveting mold corresponding to the clamping mold; the riveting mold comprises a hollow mold case, the mold case is provided with a mold hole corresponding to one side surface of the pipe fitting riveting position, a sliding block and a riveting block which moves by coordinating with the sliding block are arranged in the mold case, one side of the rack is provided with a first propelling mechanism which pushes the mold case to move in the clamping mold and a second propelling mechanism which pushes the sliding block to move in the mold case, the movement of the sliding block drives the riveting block to lead the upper end of the riveting block to eject out the mold hole; a fixed mold plate and a sliding mold plate are arranged on the rack, and the fixed mold plate and the sliding mold plate are provided with the clamping mold, the riveting mold, the first propelling mechanism and the second propelling mechanism, and upper and lower riveting molds are symmetrically arranged and are operated synchronously; the pipe fitting riveting machine has simple structure and convenient operation, realizes riveting connection among a plurality of the thin-wall pipe fittings and realizes inner riveting of the thin-wall pipe fittings.

Description

technical field [0001] The invention relates to a riveting device, in particular to a riveting machine used for pipe fitting connection. Background technique [0002] In daily life, many products are connected by multiple thin-walled pipe fittings, such as heating radiators, heat exchangers, etc. At present, there are roughly three connection methods for thin-walled pipe fittings. One is welding, but when welding The surface of metal pipe fittings will be deformed and discolored by heat. High temperature welding is also easy to perforate the pipe wall of the pipe fittings, and the welded part is easy to be corroded, and the durability of the product is poor. Or the matching internal and external threads are tapped on the pipe wall, but the threaded connection is easy to slip, and the firmness is not enough; the third is to use pipe joints to connect, that is, to use two-way or three-way pipe joints to connect multiple pipe fittings. Threads need to be provided on the pipe j...

Or the matching internal and external threads are tapped on the pipe wall, but the threaded connection is easy to slip, and the firmness is not enough; the third is to use pipe joints to connect, that is, to use two-way or three-way pipe joints to connect multiple pipe fittings. Threads need to be provided on the pipe joint, and the cost is high, and there are few applicable occasions

Technicians have also considered using riveting to connect pipe fittings, but in view of the fact that most of the existing riveting devices are used for riveting plate parts, there is little involvement in riveting pipe fittings, even if the riveting effect is not good, the structure needs to be improved
