Embodiment Construction

[0031] like Figure 2 to Figure 6As shown, it is an embodiment of the present invention, the split plug includes a fixed end 10 and a sealing end 20 detachably arranged on the fixed end 10, wherein the fixed end 10 has a first channel 100, The sealing end 20 has a second channel 200, and when the sealing end 20 is arranged on the fixed end 10, the first channel 100 of the fixed end 10 communicates with the second channel 200 of the sealing end 20, In order to enable the user to provide a suitable hydraulic fluid flow, such as high-pressure water flow, to the pipe to be processed through the first channel 100 and the second channel 200 .

[0032] as attached Figure 3 to Figure 6 As shown, the fixed end 10 further has a first connecting hole 110, the sealing end 20 includes a sealing portion 21 and a connecting portion 22, wherein the sealing portion 21 is suitable for sealingly arranged on the pipe, wherein the sealing portion 21 There is a second connecting hole 210, wherei...

Abstract

The invention discloses a split-type plug used for processing internal high-pressure forming pipe fittings, which is made of high-strength wear-resistant metal materials, and is characterized in that: the plug includes a fixed end and a sealing end, and the fixed end is fixed Connected to the external driving device, one end of the sealing end is detachably connected to the fixed end, and the other end is in contact with the end of the pipe to be processed placed in the internal high-pressure mold and can seal the pipe end of the pipe; A first channel is opened inside the sealing end, a second channel is opened inside the fixed end, and when the sealing end is connected to the fixed end, the first channel and the second channel communicate with each other, so that the user can provide a liquid flow with a suitable hydraulic pressure to the pipe to be processed through the first channel and the second channel; a liquid inlet hole is opened on the fixed end, and the liquid inlet hole is connected with the external The booster pump is connected through a water pipe.

Description

technical field [0001] The invention relates to a split-type plug used for processing internal high-pressure forming pipe fittings. Background technique [0002] The internal high pressure forming equipment generally includes an internal high pressure mold, and a cavity is formed in the internal high pressure mold, which is used to place the pipe fittings to be formed. Lateral hydraulic cylinders or other driving devices are respectively arranged on both sides of the inner high-pressure mold, and plugs are installed on the driving devices, and the plugs are used to seal the pipe fittings. When working, the external booster pump sends the water in the water tank to the inside of the pipe fitting through the liquid flow channel inside the plug, so that the hydraulic pressure inside the pipe fitting gradually increases, and with the help of this internal hydraulic pressure, the pipe fitting expands outward until it is in line with the The shape of the mold cavity is completely...
