Abstract

The invention relates to a handrail end circular arc punching and forming device. The handrail end circular arc punching and forming device comprises an upper die seat, a lower die seat and a circular arc punching mechanism installed between the upper die seat and the lower die seat, wherein the circular arc punching mechanism consists of a male die, a supporting female die, a male die fixing plate and a supporting die core, the male die fixing plate provided with the male die is arranged on the upper die seat, the supporting die core is installed on the lower die seat, the male die is vertically arranged above the supporting die core, the supporting female die is fixedly arranged under the supporting die core, and the supporting female die and the male die are located on the same vertical line. A die is convenient to manufacture and maintain and compact in structure, the design work can be greatly simplified, a design period is shortened, and the cutter design and manufacture cost is reduced.

Description

technical field [0001] The invention relates to a thin-walled steel pipe punching device, in particular to a circular arc punching forming device at the end of a railing. Background technique [0002] Pipes are widely used as parts and brackets in light industrial products. The joints of pipes and pipes need to be processed into arc-shaped curved surfaces before welding, so that the pipes can be welded together. In the past, milling, grinding wheel grinding, and gas cutting were used. Round pipe ends are used to complete the round pipe arc. This processing method has low work efficiency and poor quality stability. The cutting and lubricating oil will also pollute the inner wall of the pipe, which needs to be cleaned before welding. The oxyacetylene gas cutting is not well formed, and the grinding wheel is polished and splashed, which poses safety hazards and affects the health of workers. Contents of the invention [0003] The technical problem to be solved by the present...
