Embodiment 1

[0046] Such as Figure 4-6 Shown, a kind of copper tube bending forming device comprises:

[0047] base 1,

[0048] Chuck 2, bolt 4 Chuck 2 is installed on the bolt 4 base 1, the starting end of the copper pipe is clamped with the bolt 4 Chuck 2;

[0049] Several rollers 3 and several bolts 4 and rollers 3 are respectively installed on the bolt 4 base 1; the bolt 4 copper pipes are sequentially bent around several bolts 4 rollers 3 to form a product with several sections of bending;

[0050] Wherein, the installation position and shape of the bolt 4 chuck 2 and the bolt 4 roller 3 are set according to preset product parameters.

[0051]The base 1 is the installation basis of the chuck 2 and the roller 3, and at the same time serves as the bottom plane limit when the copper pipe is bent. After the chuck 2 and the roller 3 are installed on the base 1, when the copper pipe to be bent is bent, The base 1 is equivalent to the workbench, providing a stable foundation; when the ch...

Embodiment 2

[0061] A copper tube bending forming method, using the above-mentioned copper tube bending forming device, the steps include:

[0062] S1: According to the preset product parameters, select the corresponding chuck 2 and several rollers 3, and install the chuck 2 and several rollers 3 on the corresponding positions of the base 1;

[0063] S2: insert the starting end of the copper pipe into the bolt 4 clamp 2;

[0064] S3: Bending the copper pipe along each roller 3 .

[0065] After selecting the chuck 2 and roller 3 that match the preset product, install the chuck 2 and roller 3 at the corresponding position according to the preset product parameters. The starting end of the copper pipe fixed by the chuck 2 determines the starting position of the product. Then, the bending process is carried out along each roller 3 successively to obtain the bent pipe product 100 conforming to the preset. The present invention is applicable to the manual production of small batches of bent pip...

Embodiment 3

[0082] A bent pipe product 100 is formed by using the above copper pipe bending forming method.

[0083] Specifically, such as Figure 4 and 2 As shown, the bent pipe product 100 includes a first straight pipe section 101, a first bent pipe section 102, a second straight pipe section 103, a second bent pipe section 104, a third straight pipe section 105, and a third bent pipe section connected in sequence. 106 and the fourth straight pipe section 107.

[0084] The copper pipe bending and forming device includes a chuck 2 , a first roller 301 , a second roller 302 and a third roller 303 .

[0085] Select a reference coordinate axis to obtain the preset parameters of the product: the pipe diameter of the first straight pipe section 101, the inclination angle α of the starting end of the first straight pipe section relative to the reference axis, and the first straight pipe section 101 is selected. When the pipe diameter is suitable for the chuck 2, the chuck 2 is installed on...

Abstract

The invention relates to a copper pipe bend forming device and method and a bent pipe product. The device comprises a base, a chuck and multiple rollers; the chuck and the multiple rollers are mountedon the base; an initial end of a copper pipe is clamped with the chuck; the copper pipe is bent around the multiple rollers in sequence to form multiple sections of bent products; the mounting positions and the shapes of the chuck and the rollers are set according to preset product parameters; when the chuck is clamped with the initial end of the copper pipe, the initial position and direction ofthe copper pipe are determined; the rollers can limit the direction of the copper pipe during bending to achieve the bend forming purpose; the mounting positions and the shapes of the chuck and the rollers are set according to the preset product parameters, preset products can be obtained after bending; and the device is suitable for manual manufacturing of small-batch bent pipe products, achieves the generality under the condition of guaranteeing the bending quality of the manual bent copper pipes to meet different bending shape requirements, and meanwhile, is convenient to use.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a copper pipe bending forming device and method and a bent pipe product. Background technique [0002] In the installation of microwave amplification equipment, copper pipes need to be bent on site according to the installation location, such as figure 1 shown. Such as figure 2 and image 3 Shown is an example of a complex shape that requires bending. The smoothness of copper tube bending will directly affect the microwave signal transmission loss, and the accuracy of the bending interface will directly affect the difficulty of installation. [0003] Different microwave amplification equipment needs to bend copper tubes into different shapes, and small batch products use equipment programming to bend copper tubes, which is costly and inefficient. However, manual bending is difficult to ensure the smoothness and accuracy of copper pipe bending. Contents of the inventio...
