Abstract
An overlapping technology for cap and lining of pressure container in order to add metal lining to pressure container includes overlapping cap plate and lining plate, drilling positioning hole in the center of lining plate, plug welding it to cap plate, drilling 4 positioning holes around the center, spot welding, drilling small air holes at intervals of 300 mm, making 4-8 notches at the edge of lining plate and plug welding the air holes to cap plate. Its advantages are simplified technology and high shaping quality of lining plate.
Description
The invention belongs to sheet metal forming technology, particularly pressure vessel is as the tube potting head of boiler, basin, heat exchanger and the method for corrosion protective lining stacked moulding simultaneously.
Existing pressure vessel as boiler, gas tank, receiver, heat exchanger tank body, is tubular, is made up of the cylindrical shell end socket of cylindrical shell and two ends welding, adopts carbon sheet to make, and wall thickness is bigger, with pressure-bearing.In order to improve the Corrosion Protection of tank skin, add to establish corrosion resistant plate or copper coin lining.When end socket position lining was made, it was fan-shaped to need that the lining metal plate is divided into the 6-8 piece, spliced at the end socket position to the scene to be welded into integral body again, could guarantee that head plate and liner sheet are stacked to become one.This forming method is taken a lot of work, is required great effort, waste material, difficult quality guarantee.As adopt head plate, the stacked global formation of liner sheet, and then because of head plate and the liner sheet location is inaccurate and the punching press distortion differs, cause the edge of product uneven, the lining wrinkle can't use.
The objective of the invention is to, overcome the deficiencies in the prior art, adopt head plate and liner sheet once punch forming simultaneously become head plate in the compound belt material closely, to simplify manufacture craft, reduce cost of manufacture.
Pressure vessel head of the present invention, the stacked novel molding method of lining, its technical process is:
End socket carbon steel sheet and lining corrosion resistant plate are overlaped, and 1 diameter 4mm of stainless steel twist drill locating hole welds with plug welding and carbon steel sheet at the center point;
In the radius 50-100mm, bore 4 diameter 8mm locating holes again around central point, spot welding prevents that lining corrosion resistant plate and end socket carbon steel sheet from moving dislocation;
On the lining corrosion resistant plate, every interval 300mm drill diameter 4mm air-vent forms arrangement straggly, ventilative usefulness when type is made in voltage supply;
Offer 4-8 4 * 8mm gap, lining edge wrinkle when preventing to heat compression moulding at the circumferential edges of lining corrosion resistant plate;
Heating compression moulding;
Air-vent is welded with plug welding and end socket carbon steel sheet.
Advantage of the present invention is: when having solved pressure vessel lining being set, head plate has been simplified moulding process with the stamping forming difficult problem of liner sheet, has reduced cost of manufacture, has improved the Forming Quality of liner sheet.Be applicable to the moulding process when various pressure vessels add clad lining.
Below in conjunction with drawings and Examples, the invention is further described:
Fig. 1 is the organigram of existing pressure vessel
Fig. 2 is the liner sheet welding schematic diagram of existing pressure vessel
Fig. 3 is the end socket of pressure vessel head of the present invention, the stacked novel molding method of lining and the expanded view before the lining compacting.
Fig. 4 is the end socket of pressure vessel head of the present invention, the stacked novel molding method of lining and the organigram after the lining compression moulding
Embodiment:
As seen from Figure 1, existing pressure vessel basin is made of cylindrical shell, end socket, lining, and cylindrical shell 1 and end socket 2 adopt the 6-16mm carbon steel sheet to make, and lining 3 adopts 1-2mm corrosion resistant plate or copper coin to make.
As seen from Figure 2, the past forming method is, liner sheet is welded into 8 splicings, time-consuming, effort, and waste material, second-rate.
As seen from Figure 3, pressure vessel head of the present invention, the stacked novel molding method of lining, its technical process is: end socket carbon steel sheet and lining corrosion resistant plate are overlaped, and 1 diameter 4mm of stainless steel twist drill locating hole 4 welds with plug welding and carbon steel sheet at the center point;
In the radius 50-100mm, bore 4 diameter 8mm locating holes 5 again around central point, spot welding prevents that lining corrosion resistant plate and end socket carbon steel sheet from moving dislocation;
On the lining corrosion resistant plate, every interval 300mm drill diameter 4mm air-vent 6 forms arrangement straggly, ventilative usefulness when type is made in voltage supply;
Offer 44 * 8mm gap 7 at the circumferential edges of lining corrosion resistant plate, lining edge wrinkle when preventing to heat compression moulding.
As seen from Figure 4, behind the end socket and lining compression moulding of pressure vessel head of the present invention, the stacked novel molding method of lining, the air-vent of liner sheet is welded with plug welding and end socket carbon steel sheet, promptly finished whole stacked moulding process.
Claims (2)
1, a kind of pressure vessel head, the stacked novel molding method of lining are overlaped by end socket carbon steel sheet and lining corrosion resistant plate, it is characterized in that:
1 diameter 4mm of lining stainless steel twist drill locating hole welds with plug welding and end socket carbon steel sheet at the center point;
On the inside front cover corrosion resistant plate around central point in the radius 50-100mm, bore 4 diameter 8mm locating holes again, spot welding prevents that lining corrosion resistant plate and end socket carbon steel sheet from moving dislocation;
On the lining corrosion resistant plate, every interval 300mm drill diameter 4mm air-vent forms arrangement straggly, ventilative usefulness when type is made in voltage supply;
Offer 4-8 4 * 8mm gap, lining edge wrinkle when preventing to heat compression moulding at the circumferential edges of lining corrosion resistant plate;
Heating compression moulding;
The air-vent of lining corrosion resistant plate is welded with plug welding and end socket carbon steel sheet.
2, pressure vessel head as claimed in claim 1, the stacked novel molding method of lining is characterized in that, lining is a copper coin.
