Abstract
A kind of pipe fitting production stable-pressure device, including current divider (5), bracket (3), mouth mold (8), plug (6), gas-guide tube (2), the current divider (5) is fixed on bracket (3), air inlet (4) are set on the bracket (3), the gas-guide tube (2) is also secured on bracket (3), described gas-guide tube (2) one end and air inlet (4) connection, the other end is connected with the central through hole (7) on plug (6), one end connection one conical separator tube (71) of the central through hole (7) far from gas-guide tube (2), the separator tube (71) is connect with buffer area (72), buffer area (72) is round tube, its internal diameter is not more than the internal diameter of mouth mold (8).By setting separator tube and buffer area, air-flow gradually slows down at separator tube when inflation, and tends towards stability at separator tube, keeps the air pressure of pipe fitting both ends more stable, to improve yield rate, decreases the ratio of pipe fitting waste product, reduce production cost.
Description
Technical field
The present invention relates to a kind of pipe fittings to produce stable-pressure device, specifically a kind of in still highly uniform steady of pipe fitting pressure at two ends
Pressure device.
Background technique
Internal pressure sizing is one of the main method of current tube forming, is primarily used to the tubing of production major diameter.Internal pressure
Sizing is compressed air will to be filled with inside tubing, and making tubing, outer wall is attached to calibration sleeve inner surface and is cooled under the influence of gas
Type.But at pipe fitting both ends, due to keeping the admission line of pressure that can generate air-flow in air inlet, make pipe fitting end close to mouth
Local decompression is formed at mould, causes to be easy to produce the problems such as not round and smooth or outer surface is not round and smooth on pipe material inner wall here.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides one kind to make pipe fitting production medial end portions air pressure and internal gas
The pipe fitting of pressure more evenly produces stable-pressure device, keeps the end yield rate of pipe fitting higher, save the cost.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of pipe fitting produces stable-pressure device, including shunts
Device, bracket, mouth mold, plug, gas-guide tube, the current divider are fixed on bracket, and air inlet is arranged on the bracket, described to lead
Tracheae is also secured on bracket, and described gas-guide tube one end and air inlet connection, the other end are connected with the central through hole on plug,
One end connection one conical separator tube of the central through hole far from gas-guide tube, the separator tube are connect with buffer area, and buffer area is
Round tube, internal diameter are not more than the internal diameter of mouth mold.
Preferably, the axial length of the buffer area is 10-20cm.
Preferably, the axial length of the separator tube is 20-30cm.
Further, drainage air pressure regulator is connected on the air inlet.
By setting separator tube and buffer area, air-flow gradually slows down at separator tube when inflation, and tends at separator tube
Stablize, to guarantee gentler in the air-flow at pipe fitting both ends, keeps the air pressure of pipe fitting both ends more stable, to improve yield rate, also subtract
Lack the ratio of pipe fitting waste product, reduces production cost.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
1- drainage air pressure regulator, 2- gas-guide tube, 3- bracket, 4- air inlet, 5- current divider, 6- plug, the center 7- are logical
Hole, 71- separator tube, the buffer area 72-, 8- mouth mold.
Specific embodiment
The invention will be further described below.
As shown in Figure 1, the present invention includes current divider 5, bracket 3, mouth mold 8, plug 6, gas-guide tube 2, the current divider 5 is solid
It is scheduled on bracket 3, air inlet 4 is set on the bracket 3, the gas-guide tube 2 is also secured on bracket 3, described 2 one end of gas-guide tube
With 4 connection of air inlet, the other end is connected with the central through hole 7 on plug 6, the described one end of central through hole 7 far from gas-guide tube 2
The conical separator tube 71 of connection one, the separator tube 71 are connect with buffer area 72, and buffer area 72 is round tube, and internal diameter is not more than mouth mold
8 internal diameter.The axial length of the buffer area 72 is 10-20cm.The axial length of the separator tube 71 is 20-30cm.It is described
Drainage air pressure regulator 1 is connected on air inlet 4.
In production process, especially at the beginning, when inflating pressure stabilizing, air-flow just driven at pipe fitting both ends it is slow, to make two
End be not likely to produce because air-flow it is too fast caused by negative pressure at air-flow tail end, air pressure is more stable, to improve both ends yield rate, drops
Low production cost.
