Abstract

The invention discloses a sheet metal processing method for a conical pipe. The sheet metal processing method for the conical pipe comprises a to-be-processed workpiece and further comprises a bottom die, wherein the bottom die is mounted on an externally connected sheet metal bending machine; a tool holder capable of moving up and down and a pressure head connected with the tool holder are arranged above the bottom die respectively; the workpiece is placed on the bottom die; and the pressure head is arranged over against the bottom die and presses downwards the workpiece through the tool holder. According to the sheet metal processing method for the conical pipe, the bottom die of the sheet metal bending machine and the tool holder connected with the pressure head are used in a matching manner, so as to provide convenience for processing the workpiece and reduce the intensity of manual manufacture. Meanwhile, a welding procedure for manufacturing the workpiece is omitted, so as to improve the attractiveness of the workpiece and eliminate potential safety hazards caused by welding in manual manufacture. Moreover, compared with the manual manufacture, the method effectively improves the accuracy of the workpiece by the use of the bottom die of the sheet metal bending machine and the tool holder connected with the pressure head.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a sheet metal processing method of a tapered pipe. Background technique [0002] Sheet metal is a comprehensive cold working process for sheet metal. At present, the tapered tubular sheet metal components basically rely on hand-made. For the tapered tubular sheet metal components with a plate thickness greater than 3mm and a small diameter less than 200mm, manual production is usually done by half-fabrication and then welding. It not only increases labor intensity, but also affects the appearance of components, especially for components used in pressure vessels, it will increase the hidden dangers caused by welding. Contents of the invention [0003] The purpose of the present invention is to provide a sheet metal processing method for tapered pipes to solve the problems of high labor intensity, affected appearance and hidden dangers caused by welding caused by the existing ma...
