Abstract
The utility model relates to a submersible welding miniature draining device which is formed by the joint connection of an insulating sleeve, a connecting sleeve, a drainage cover and a sealing gasket, wherein the insulating sleeve is screwed with inner screws of the connecting sleeve through outer screws, the drainage cover is screwed with the inner screws of the connecting sleeve through the outer screws, and the drainage cover is affixed with the sealing gasket through adhesive. The utility model has the advantages of simple structure, easy use, reliability, economy and practicability. A local no water area is generated when the underwater welding is carried out, the wet way weld joint is changed to the local dry way weld joint, so the weld quality is enhanced.
Description
The utility model is to weld miniature drainage arrangement under water, belongs to underwater welding technology equipment.
Self-protection flux-cored wire welds under water with underwater electrode wet method welding and compares, and has the efficient height, is easy to realize the advantage of mechanization etc.But owing to still weld under the environment of wet method, particularly when deep water (when pressure is greater than 0.6～0.7Mpa under water) exists the protection effect of self-protection flux-cored wire significantly to descend, shortcoming and problem that weldquality is difficult to guarantee etc.In order to ensure the quality of products, under the high pressure of water, adopt the method that adds gas shield usually.
The purpose of this utility model is exactly in order to overcome and to solve shortcoming and the problem that existing underwater electrode or self-protection flux-cored wire wet method weldering under water exist protection weak effect, the weldquality of self-protection flux-cored wire to be difficult to guarantee etc.; research and design is a kind of welds miniature drainage arrangement under water; it can make when welding under water and produce a local no aqua region between two electrodes; create the environment that welds in the similar air; become wet method and be welded as the local dry cavity welding, thereby weldquality is improved greatly.
The utility model is realized by following technical proposals: weld the structure of miniature drainage arrangement and operation principle schematic diagram under water shown in Fig. 1～2, it is connected and composed jointly by insulation sleeve 1, adapter sleeve 2, drainage cover 3, sealing gasket 4, and its interconnected relationship is: insulation sleeve 1 spins mutually by the external screw thread of itself and the internal thread and the adapter sleeve 2 of adapter sleeve 2; Drainage cover 3 spins mutually by the internal thread and the adapter sleeve 2 of self external screw thread and adapter sleeve 2; Sealing gasket 4 is bonding by adhesive and drainage cover 3; When welding under water, welding gun 5 spins mutually by the internal thread of external screw thread and insulation sleeve, workpiece 9 welding gun 5 by the high pressure that applies at this miniature drainage arrangement under with close the connecting of sealing gasket of this miniature drainage arrangement.
Style of work principle of the present utility model is as follows: this welds miniature drainage arrangement under water and is installed on the wire feed electrode, insulation sleeve can be done the electricity isolation with this device case and welding gun electrode, and sealing gasket can make drainage cover contact and intercept in the outside current direction cover chamber with the work intercropping is flexible.When adopting flux-cored wire to weld under water, steam when gas that produces by solder wire material self and water vapor arranges the water in this miniature drainage arrangement case, form the no aqua region of a part, electric arc is in this zonal combustion, and becoming under water, wet method is welded as the local dry cavity welding.For example, before the welding, a zone in the drainage cover chamber, the b zone of honeybee pad has been full of water.During welding, electric arc is in the chamber internal combustion, and the steam when gas that solder wire material self is produced and water vapor is more and more, and the pressure in the chamber is increasing.When cavity pressure during greater than its all edge water pressure, the water in the chamber is drained into outside the chamber by sealing gasket.At this moment, loose sealing gasket plays " check valve ", and it can allow unnecessary gas discharge and water does not enter the weld zone.So the weld zone in water environment has just formed the anhydrous similar airborne zone of a part, the environment burning that electric arc just welds in this similar air makes weldquality significantly improve than the wet method welding.Along with constantly carrying out of welding, the right that this drainage arrangement is done as shown in the figure moves, sealing gasket is owing to the high temperature of weld seam the part scaling loss takes place, forms cavity C, cavity C is owing to lag behind arc zone one segment distance, make weld seam be unlikely to enter immediately in the water, make weld seam that certain slow cooling effect be arranged, more help improving the mechanical performance of weld seam.
The utility model is compared with existing underwater welding technology equipment, have following advantage and beneficial effect: (1) produces a local no aqua region because the utility model can make when welding between two electrodes under water, can create the environment that welds in the similar air, become wet method and be welded as the local dry cavity welding, welding quality is improved greatly; (2) can be installed on the wire feed electrode owing to the utility model, steam in the time of making gas that flux-cored wire produces and water vapor during welding arranges the water in this device shell---and do not need to add gas shield, self forms a stable part does not have the pool, and electric arc just burns in this bubble; Use the variable wet method under water of this miniature drainage arrangement to be welded as the local dry cavity welding, this has not only eliminated the interference under water of welding position regional area, improved the stability of arc burning, and reduced the harm of hydrogen, butt welded seam has played effective metallurgical protective effect, and weldquality can be significantly improved; (3) this miniature drainage arrangement can overcome and solve existing shortcoming of prior art equipment and problem fully; (4) this miniature drainage arrangement simple in structure, easy to use, reliable, economical and practical, make having a extensive future of submarine mechanicalization, automation welding.
Below Figure of description is further specified as follows: Fig. 1～Fig. 2 is structure and the operation principle schematic diagram that welds miniature drainage arrangement under water, and wherein: Fig. 2 is that the A-A of Fig. 1 schemes to analysing and observe (operation principle); 1 is insulation sleeve among each figure, the 2nd, and adapter sleeve, the 3rd, drainage cover, the 4th, sealing gasket, the 5th, welding gun, the 6th, conduction is chewed, and the 7th, welding wire, the 8th, electric arc, the 9th, workpiece; A is the zone in the drainage cover chamber before the welding; B is water-filled sealing gasket zone; When being welding, c makes the cavity of sealing gasket part scaling loss formation owing to the high temperature of weld seam.
Embodiment of the present utility model can be as follows: each parts of 1. pressing design shown in Figure 1, this device of processing and manufacturing.For example: insulation sleeve 1 can select for use the plastics king to form with machine-tooled method car system; Adapter sleeve 2 can select for use brass rod to form with processing method car system; Drainage cover 3 can select for use brass to form with machine-tooled method car system equally; Sealing gasket can be selected for use the sponge cutting to dig a hole and form; 2. according to described mutual alignment of top specification and interconnected relationship connection is installed then, insulation sleeve 1 is spun mutually by the internal thread of external screw thread with adapter sleeve 2, drainage cover 3 is spun mutually by the internal thread of external screw thread with adapter sleeve 2, can select for use epoxy resin drainage cover and sealing gasket to be bonded together as adhesive; When 9. welding under water, welding gun 5 is screwed in the internal thread of the insulation sleeve 1 of this device by external screw thread just can uses this device to weld under water again.The inventor is the manufacturing cost device, and has carried out welding under water with the welding gun of CV500-1 type Lincoln welding machine, makes the weldquality of workpiece that clearly raising be arranged.
