U-shaped pipe pushing device, automatic pipe passing device and operation method of U-shaped pipe pushing device

Abstract

The invention provides a U-shaped pipe pushing device, which comprises a plurality of linear modules in parallel arrangement, wherein each linear module respectively comprises a linear guide rail, in addition, the guide directions of the linear guide rails are identical, a clamping device used for clamping two parallel straight pipes of U-shaped pipes is respectively arranged on a slide seat of each linear guide rail, a plurality of clamping grooves for accommodating U-shaped parts of the U-shaped pipes are parallelly formed in the clamping devices, and the clamping directions of the clamping devices are vertical to the support direction of the slide seats. Through the clamping devices, pipelines of linear parts of a plurality of U-shaped pipes are mutually parallelly clamped between the clamping devices, during the transmission, the U-shaped pipes are pushed in the length direction of a linear pipeline, through the arrangement of a plurality of parallel linear modules, during the conveying, the U-shaped pipes are pushed in the length direction of the linear pipelines, through the arrangement of a plurality of side-by-side modules, the linear modules positioned in different positions are controlled to move in different work hours, the installation intensity in different positions of fins and the U-shaped pipes are continuously regulated in the installation process, and the pipe passing difficulty is reduced. The invention also provides an automatic pipe passing device. The invention also provides an operation method of the U-shaped pipe pushing device.

Description

technical field [0001] The invention relates to the technical field of automatic pipe threading machine production, and more specifically relates to a U-tube pushing device, an automatic pipe threading machine and an operation method for the U-tube pushing device. Background technique [0002] In the prior art, U-shaped tubes are used as a heat transfer device for gas-liquid transfer, and its structure includes a plurality of U-shaped tubes arranged in parallel in the length direction. A plurality of fixed support plates in the length direction are supported, and U-shaped tubes are interspersed and arranged on the fixed support plates. [0003] In the prior art, the manual operation method is often used to realize the pipe threading work of the U-shaped pipe on the fixed support component. The platform clamps the pre-piercing device. Then take the long U-shaped tube. The U-shaped tube is generally a copper tube. Manually use one hand to correct the long U copper tube, alig...

Problems solved by technology

Then take the long U-shaped tube. The U-shaped tube is generally a copper tube. Manually use one hand to correct the long U copper tube, align it with the hole on the pre-piercing tube device, and push the long U into the corresponding hole with the other hand. In the hole of the pre-threading device, this method has high labor intensity, low efficiency, and is easy to cause damage to the pipe-threading parts. It is difficult for unskilled employees to perform this job, and manual pipe threading is not conducive to heat transfer products. Realization of flow production
