Abstract

The invention provides an adjustable die frame for a heat exchanger micro-diameter thin-wall pipe bending die. The adjustable die frame comprises a compressing part, a fixed connecting part and a guide part. The guide part is fixed to a workbench. Displacement of the compressing part in a certain direction is restrained on the guide part. The guide part is connected with the workbench through threads. All the parts of the adjustable die frame are simple in working principle, machining is convenient, replaceability is high, and the adjusting range is large. The locating error can be reduced during use, and forming quality is improved.

Description

technical field [0001] The invention provides an adjustable formwork used for bending molds of micro-diameter thin-walled pipes for heat exchangers, and in particular relates to an adjustable formwork with a locking guide device for a new type of bending micro-thin-walled pipe molds, which is suitable for The invention relates to the precise bending and forming of fine thin-walled pipes, and belongs to the field of aerospace science and technology. Background technique [0002] With the development of aerospace science and technology, the bending process of pipes is often involved in its manufacturing field. The bending of pipes in different parts usually involves different pipe diameters, different bending radii, and different bending angles. For different bending For pipe fittings, the bending process usually used is also different. According to the bending method, it can be divided into stretch bending, winding bending, push bending, rolling bending and pressing bending;...
