A Bending Die for Bending Micro-diameter Thin-Wall Pipes for Heat Exchangers

Abstract

The invention provides a bending mold for bending a micro-diameter thin-wall pipe of a heat exchanger. The bending mold is composed of a working part, a guiding part and an auxiliary accessory; according to the connection relation between the working part, the guiding part and the auxiliary part, a part of the working part is movably connected and fixed on the guiding part so that the working part can generate displacement in the rotating direction, and the other part of the working part is movably connected and fixed on a mold frame and is used for providing the compressing guiding effect for forming; the guiding part is fixed on a workbench and provides torque for the forming of the micro-diameter thin-wall pipe; and the auxiliary accessory is connected and fixed on the working part, can rotate along with the working part and is used for providing auxiliary help for the forming process. The bending mold has the advantages that the working principle is simple, the machining is convenient, the replaceability is high, the cost is low, the quality of the formed surface can be improved, and the bending angle of the pipe can be mastered in real time through the readings of a dial 5.

Description

technical field [0001] The invention provides a mold for bending micro-diameter and thin-walled pipes of heat exchangers, which is a bending mold for bending micro-diameter and thin-walled pipes of heat exchangers, and especially relates to a new type of multi-station adjustable A bending die with its own clamping tool is suitable for 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...

AI Technical Summary

Problems solved by technology

At present, the existing pipe bending equipment mainly uses the rigidity and friction of the pipe itself and the torque generated by the equipment to fix it in the clamping method, but it cannot provide greater rigidity for micro-diameter thin-walled pipes, so the traditional clamping method is not suitable. It is applicable again, and at the same time, the small rigidity of the micro-diameter thin-walled pipe also brings about the problems of difficult positioning and complicated operation, so the existing pipe bending equipment on the market cannot solve the existing problems
