Problems solved by technology

Since the movable dies and guide plate processing grooves in the pipe bending field are consistent with the pipe diameter, one pair of molds can only be used for one pipe diameter. Because there are many different pipe diameters for air-conditioning pipes, it is necessary to manufacture a large number of molds. It is troublesome to adapt to different pipe diameters and change the mold every time

Embodiment Construction

[0009] like figure 2 As shown, a multi-purpose bending pipe mold includes a fixed mold 5, a movable mold 4 and a guide plate (not shown in the figure) matched with the fixed mold 5, and is characterized in that one end of the movable mold 4 is provided with a special-shaped processing groove , the special-shaped processing groove is formed by connecting two arc surfaces with different radii. R2, where R2>R1, smooth connection between the first arc surface and the second arc surface (tangential connection between the first arc surface and the second arc surface), the stent is opened with the special shape The processing groove matches the semicircular processing groove, and the radius of the processing groove depends on the pipe diameter. According to a preferred embodiment of the present invention, the radius R1 of the first arc surface is 4-8mm, the radius R2 of the second arc surface is 6-30mm, the depth H of the processing groove is 3-10mm, and the width of the processing...

Abstract

The invention discloses a multi-purpose pipe bending mould which comprises a fixed mould and a movable mould. The multi-purpose pipe bending mould is characterized in that a special-shaped processing groove is formed on the movable mould and is formed by connecting two arc surfaces of different radii, the middle portion of the special-shaped processing groove is a first arc surface, two ends of the first arc surface are respectively connected with a second arc surface, the first arc surface and the second arc surface are smoothly connected, and a semi-circular processing groove is formed on the fixed mould. By improving processing grooves of the movable mould and a guide plate, the multi-purpose pipe bending mould can meet the requirement of bending pipes of different diameters. The multi-purpose pipe bending mould has the advantages of being capable of reducing mould manufacturing quantity greatly, reducing mould costs, shortening mould changing time, improving production efficiency, and integrating the management optimization and the design standard of the mould.

Description

technical field [0001] The invention relates to the field of pipe bends for automobile air conditioners, in particular to a multipurpose pipe bend mold which can adapt to different pipe diameters. Background technique [0002] like figure 1 , the current common way to bend the pipe is that the movable mold 1 and the fixed mold 3 clamp the pipeline, and the guide plate 2 uses the fixed mold 3 as the radius to achieve the purpose of bending. Since the movable dies and guide plate processing grooves in the pipe bending field are consistent with the pipe diameter, one pair of molds can only be used for one pipe diameter. Because there are many different pipe diameters for air-conditioning pipes, it is necessary to manufacture a large number of molds. It is troublesome to adapt to different pipe diameters and change the mold every time. Contents of the invention [0003] The purpose of the present invention is to provide a multi-purpose elbow mold to adapt to more pipe diamet...
