Problems solved by technology

[0003] At present, the method used to expand the pipe fittings is usually to manually insert the expansion head into the metal pipe, expand the metal pipe, and then pull out the expansion head. Manual expansion will inevitably cause the inclination of the expansion position of the handlebar pipe fitting, which is labor-intensive and expensive. The production efficiency is low, and when the expansion rod is drawn out, it is difficult to remove the expansion rod and the pipe fittings smoothly due to the tight connection between the expansion rod and the pipe fittings

Abstract

The invention discloses a pipe expanding device for the production of bicycle handlebars, which comprises a fixed seat, a hydraulic machine is fixedly connected to the fixed seat, a pipe expanding head is fixedly connected coaxially to the hydraulic rod, and a working box is fixedly connected to the fixed seat. The hydraulic rod is fixedly connected with a mounting plate, the mounting plate is fixedly connected with a telescopic rod, the telescopic rod is fixedly connected with a limit ring, the telescopic rod is sleeved with a spring, and the two ends of the spring are respectively offset against the mounting plate and the limit ring, and the working A baffle is slidably connected to the box, a placement hole is opened on the baffle, a rectangular block is fixedly connected to the baffle, a slanting rod is fixedly connected to the limit ring, and the slanting rod is slidably connected in the rectangular block. Righting mechanism for straightening handlebar fittings. In the present invention, the handlebar pipe is vertically limited by setting the baffle plate, the handlebar pipe is horizontally limited by setting the copy mechanism, and the expansion pipe head can be smoothly separated from the handlebar pipe by setting the separation mechanism and the lubricating mechanism. .

Description

technical field [0001] The invention relates to the technical field of tube expansion devices, in particular to a tube expansion device used in the production of bicycle handlebars. Background technique [0002] The handlebar is one of the necessary parts of the bicycle. It is generally made of pipe. The handlebar needs to be expanded during production and processing. The bicycle handlebar pipe fittings are enlarged, and then the lifting pipe head is pulled out, and the diameter of the pipe fittings will be enlarged. [0003] At present, the method used to expand the pipe fittings is usually to manually insert the expansion head into the metal pipe, expand the metal pipe, and then pull out the expansion head. Manual expansion will inevitably cause the inclination of the expansion position of the handlebar pipe fitting, which is labor-intensive and expensive. The production efficiency is low, and when the expansion rod is drawn out, it is difficult to remove the expansion ro...
