Straight tube thinning device

Abstract

The invention relates to a straight tube fine-drawing device, comprising a rack; a working table is arranged on the rack; a stretching and heating tooling is installed on the working table; the stretching and heating tooling comprises a clamping mechanism for fixing a fixed end of a straight tube, a heating mechanism for heating a to-be-stretched end of the straight tube, and a stretching mechanism for stretching the heated part of the straight tube for reducing; the clamping mechanism and the stretching mechanism are respectively positioned at the two ends of the heating mechanism, and can separately go close to or away from the heating mechanism. The straight tube fine-drawing device provided by the application can realize the rapid reducing of the nylon tubes for automobiles, is exquisite in structure and reasonable in design, guarantees the precision and high efficiency of a reducing operation, and can realize batch production operation.

Description

technical field [0001] The invention relates to straight tube stretching equipment, in particular to a nylon straight tube stretching equipment. Background technique [0002] China's automobile industry is developing rapidly, and the requirements for auto parts have also been greatly improved. Nylon (polyamide) pipes for automobiles have been widely used. In the process of automobile assembly and production, nylon pipes need to be equipped with valves or joints to realize pipeline At the same time, it is necessary to develop valves or joints of corresponding specifications. At present, different brands and types of cars have their own specifications of nylon tubes, resulting in a lot of accessories for valves or joints. In order to match the pipeline design of customers, it is often necessary to Designing valves or fittings to match the piping specifications results in high costs and development risks for developing new specification valves or fittings.
