Abstract
The invention discloses a novel cylinder barrel flange welding process, and belongs to the field of machining of oil cylinders. The novel cylinder barrel flange welding process comprises the following machining steps: 1) a connecting ring having the outer diameter same with the inner diameters of a cylinder barrel flange and a cylinder barrel is manufactured; 2) two sides of the connecting ring are respectively inserted in connecting ports of the cylinder barrel flange and the cylinder barrel; and the ports of the cylinder barrel flange and the cylinder barrel are aligned; 3) the connecting places of the cylinder barrel flange and the cylinder barrel are welded; and 4) after the welding is finished, and when an inner hole of the cylinder barrel is bored, fusion welding lines in the connecting ring and a groove are bored off. The process reduces the welding rejection rate of the cylinder barrel flange and the cylinder barrel of a hydraulic cylinder, improves the production efficiency and the welding quality, and achieves a fatal effect on improvement of the overall sealing performance of the hydraulic cylinder and prolonging of the service life of an oil cylinder.
Description
Technical field
The invention belongs to a kind of welding procedure, specifically, more particularly to a kind of novel cylinder barrel flange welding technique.
Background technology
With hydraulic cylinder research and development and the continuous development of manufacturing technology, it is desirable to the production efficiency and product in hydraulic cylinder manufacture process
Quality is improved constantly, cost is reduced.In order to reduce the percent defective of hydraulic cylinder drum flange and cylinder barrel welding, improve production efficiency
And welding quality, needs are constantly optimized, are tested to welding structure at this, and determine optimal welding structure, to improving hydraulic pressure
Cylinder overall sealing performance, prolongation oil cylinder service life play vital effect.
Prior art：The hydraulic jack of cylinder cap and cylinder barrel mode with bolts, cylinder barrel flange welding existing two
The scheme of kind, one kind process boss insertion cylinder barrel flange for cylinder barrel end face and are welded, and another kind adds for cylinder barrel end face of flange
Work goes out boss insertion cylinder barrel and is welded, and the effect of boss is：Cylinder barrel flange and cylinder barrel are supported during welding.
Prior art shortcoming：After boring pressure, cylinder barrel flange is more with cylinder barrel seam crossing burr, easily scratches sealing member and causes internal hemorrhage due to trauma,
Polishing is needed, production efficiency is relatively low；After welding, weld seam bottom is also easy to produce pore, affects welding quality, reduces weld strength, cylinder barrel
After boring pressure, percent defective is high.
The content of the invention
It is an object of the present invention to provide a kind of novel cylinder barrel flange welding technique, to overcome prior art middle cylinder drum flange and cylinder
The drawbacks described above that the welding procedure of cylinder is present.
The present invention employs the following technical solutions realization：
A kind of novel cylinder barrel flange welding technique, including following procedure of processing：
1) external diameter is made with cylinder barrel flange and internal diameter of cylinder identical connection ring；
2) both sides of connection ring are plugged in the connectivity port of cylinder barrel flange and cylinder barrel respectively, and by cylinder barrel flange and cylinder
The port alignment of cylinder；
3) cylinder barrel flange and cylinder barrel junction are welded；
4), after the completion of welding, connection ring and groove fusion weld seam whole boring are gone when inner hole of cylinder boring is pressed.
The cylindrical middle processing of the connection ring is provided with a circle groove
Compared with prior art, the invention has the beneficial effects as follows：Present invention process reduces hydraulic cylinder drum flange and cylinder
The percent defective of cylinder welding, improve production efficiency and welding quality, use the longevity to improving hydraulic cylinder overall sealing performance, extending oil cylinder
Life plays vital effect.

Fig. 2 is the partial structural diagram in flange and cylinder barrel welding process；
Fig. 3 is the A portions enlarged drawing of Fig. 2；
Fig. 4 is the structural representation of connection ring.
In figure：1st, cylinder barrel flange；2nd, cylinder barrel；3rd, connection ring；4th, groove.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of novel cylinder barrel flange welding technique, including following procedure of processing：
1) external diameter and 2 internal diameter identical metal connection ring 3 of cylinder barrel flange 1 and cylinder barrel are made, and in the outer of connection ring 3
Groove 4 is enclosed in processing one in the middle of circle；
2) both sides of connection ring 3 are plugged in the connectivity port of cylinder barrel flange 1 and cylinder barrel 2 respectively, and by cylinder barrel flange 1
Align with the port of cylinder barrel 2；
3) cylinder barrel flange 1 and 2 junction of cylinder barrel are welded；
4), after the completion of welding, weld seam whole boring will be merged when 2 endoporus boring of cylinder barrel is pressed at connection ring 3 and groove 4 and is gone.
Connection ring 3 is played a supporting role in welding process, and 3 outer round recessed 4 of connection ring plays aerofluxuss and weldering in welding
Seam bottom moves down effect, and whole borings after the completion of welding are gone, and weld seam bottom does not have pore, and the cost of waste of material is reduced；
Be present Burr Problem with cylinder barrel flange 1 and 2 seam crossing of cylinder barrel in boring pressure back clevis 3, it is not necessary to polish, production efficiency is carried
It is high.
