Problems solved by technology

[0002] At present, the copper joint in the prior art is composed of a pipe body, one end is a fixed part, the other end is a connecting part, and the connecting part is an end connected to a hose. The connecting part is generally equipped with a toothed structure, and the toothed structure is high On the peripheral surface of the rest of the hose, since the joint of the hose is stretched by the tooth structure when the hose is plugged in, the hose is prone to thinning or even damage at the joint, and during use, the pressure When it suddenly becomes larger, it is easy to disengage or leak, especially if there is no additional fastener, the above situation is more likely to occur; and after the fastener is added, the hose will become thinner due to the wall thickness of the hose connection. Easy to break at thinning; also, some hoses stiffen at low temperatures, making it easier for the hose to fall off
Therefore, the copper pipe joints in the prior art have the problems of poor connection stability and poor applicability

Embodiment 1

[0030] The production method of the copper joint described in any one of the preceding claims, comprising the following steps:

[0031] 1. Cutting blank tube: the length of blank tube is 1000mm;

[0032] 2. Machining: During processing, the blank tube is inserted from the rear end of the CNC machine tool to the fixture, and the rear end of the CNC machine tool is equipped with an automatic feeding device for the blank tube; and the cutter head starts processing from the fixed part 3. The connection part 1 is cut off, and the process before cutting is the rounding of the inner hole of the connection part 1, that is, before cutting, the inner hole of the connecting part 1 is rounded; the inner hole rounding of the connection part 1 is performed using a special tool 9 ;

[0033] 3. After collecting and inspecting the blanks in step 2, they can be packed.

[0034] Described special cutter 9 comprises cutter bar 91 and cutter head 92, and described cutter head 91 is fixed on an e...

Embodiment 2

[0036] The production method of the copper joint described in any one of the preceding claims, comprising the following steps:

[0037] 1. Cut blank tube: the length of blank tube is 1500mm;

[0038] 2. Machining: During processing, the blank tube is inserted from the rear end of the CNC machine tool to the fixture, and the rear end of the CNC machine tool is equipped with an automatic feeding device for the blank tube; and the cutter head starts processing from the fixed part 3. Cut off at the connection part 1, and the previous process of cutting is the rounding of the inner hole of the connecting part 1; the rounding of the inner hole of the connecting part 1 is performed with a special tool 9;

[0039] 3. After collecting and inspecting the blanks in step 2, they can be packed.

Abstract

A copper connector comprises a pipe body. The pipe body is divided into a connecting part (1), a transition part (2) and a fixing part (3). The outer diameter of the transition part (2) is larger thanthat of the connecting part (1), the outer diameter of the transition part (2) is smaller than that of the fixing part (3), and the peripheral face of the transition part (2) is provided with a firstannular groove (4). The corresponding diameter of the bottom face of the first annular groove (4) is larger than the outer diameter of the connecting part (1). The connecting part (1) is divided intoa sawtooth section (11) and a smooth section (12). A copper connector production method comprises the first step of blank pipe cutting, the second step of machining and the third step of collecting and checking of falling materials in the second step and then packaging. Compared with the prior art, the copper connector and the copper connector production method have the beneficial effects that connecting stability and applicability are good, and the production cost is low.

Description

technical field [0001] The invention relates to a joint, in particular to a copper joint used for connecting hoses and a production method thereof. Background technique [0002] At present, the copper joint in the prior art consists of a pipe body, one end is a fixed part, the other end is a connecting part, and the connecting part is the end connected to the hose. The connecting part is generally equipped with a toothed structure, and the toothed structure is high As for the peripheral surface of the remaining parts, since the connection of the hose is greatly stretched by the tooth-like structure when the hose is plugged in, the connection of the hose is prone to thinning or even damage, and during use, the pressure When it suddenly becomes larger, it is easy to disengage or leak, especially if there is no additional fastener, the above situation is more likely to occur; and after the fastener is added, the hose will become thinner due to the wall thickness of the hose con...
