Abstract
The invention relates to a brake hose joint using ring welded body for sealing and pressing a lining core. The brake hose joint comprises a metal joint (1) and a lining core (2), and is characterized in that the lining core (2) is connected with the metal joint (1) through riveting, and a ring welded body (3) is filled in a gap between the metal joint (1) and the lining core (2). No gap between the metal joint and the lining core of the brake hose joint using the ring welded body for sealing and pressing the lining core is ensured. The sealing between the metal joint and the lining core can reach the sealing requirement, the metal joint and the lining core are directly welded and the potential defects of air blisters, insufficient welding and the like are thoroughly avoided. After the lining core is riveted, the lining core is not deformed and cracked, the leakage of an assembly is prevented from being caused and the potential hazards are prevented.
Description
Technical field
The present invention relates to a kind of air brake hose nipple that adopts annular welds sealing pressing embedding lining core, this joint is the metal joint that the special seal requirement is arranged in hydraulic pipe line, the metal joint that particularly the automobile hydraulic flexible pipe is used.
Background technique
Metal joint, owing to being subject to the basic combination that adopts body and lining core of processing technology restriction, can be divided into nipple and interior Threaded Connector Coupling according to the Placement of joint.Served as a contrast core and joint body is mainly to adopt following several modes to process in the past:
1) as Fig. 1, the rear secondary pressurized sealing of packing into of lining core.Tolerance of size during due to manufacture causes the poor sealing performance of product, may have gap.
2) as Fig. 2, the lining core is packed into rear with melting welding or soldering (melting the scolders such as silver-colored tin alloy), and this technique may can not reach seal request because insufficient solder connection causes joint, is directly welded, and has the defect hidden danger of sand holes, rosin joint etc.
3) as Fig. 3, joint adopts the integrated type processing structure, because the wall thickness of lining core only has 0.5-0.6mm, in processing, can cause wall thickness deviation even wall break, once and lining core integral joint is packed into after the rubber hose riveted, this risk is difficult for discovering, the lining core has Wall-Thickness Difference, deform after riveted and break, causing assembly to leak, having very large hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of air brake hose nipple that adopts annular welds sealing pressing embedding lining core.
Technological scheme of the present invention is:
A kind of air brake hose nipple that adopts annular welds sealing pressing embedding lining core, comprise metal joint 1 and lining core 2, and described lining core 2 is connected with metal joint 1 riveting, in the gap between metal joint 1 and lining core 2, is full of annular welds junctor 3.
Between described metal joint 1 and lining core 2, by molten solder, connect.
Described metal joint 1 and the lining core 2 between without any gap and pore.
The invention has the beneficial effects as follows:
Between the metal joint of the air brake hose nipple of employing annular welds sealing pressing embedding lining core of the present invention and lining core, guarantee without any gap.Can reach seal request between metal joint and lining core, directly be welded, thoroughly avoid the defect hidden danger of sand holes, rosin joint etc.To can not deform and break after lining core riveted, and prevent from causing assembly to leak, avoid hidden danger.
The accompanying drawing explanation
Fig. 1 is that the rear secondary pressurized sealing of packing into of the lining core of prior art may exist the structural representation in gap.
Fig. 2 is the lining core of the prior art rear structural representation with melting welding or soldering of packing into.
The later structural representation of rubber hose riveted once the lining core integral joint that Fig. 3 is prior art is packed into.
After Fig. 4 is metal joint of the present invention and lining core assembling and pressing, through the structural representation of constant riveting for the second time.
Fig. 5 is the structural representation of embodiments of the invention one.
Fig. 6 is the structural representation of embodiments of the invention two.
Fig. 7 is the structural representation of embodiments of the invention three.
In figure: 1 is that metal joint, 2 is the annular welds junctor for serving as a contrast core, 3.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 4 to Fig. 7, a kind of air brake hose nipple that adopts annular welds sealing pressing embedding lining core, comprise metal joint 1 and lining core 2, and described lining core 2 is connected with metal joint 1 riveting, in the gap between metal joint 1 and lining core 2, is full of annular welds junctor 3.
Between metal joint 1 and lining core 2, by molten solder, connect.
Manufacturing procedure of the present invention is:
1, as Fig. 4, after metal joint and lining core assembling and pressing, must be through constant riveting for the second time, to guarantee intensity and the sealing after combination.
2, select to adapt to the electrode tool of the special material of size, to the place of riveted for the second time melting welding.
Present technique adopts annular solder technology fusing bulk material to make to serve as a contrast core after by the press-fiting of butt joint, punching press sealing again and joint becomes one, and has guaranteed sealing and the safety reliability of joint.
As Fig. 5,6,7, it is 3 kinds of different embodiments' of the present invention structural representation.
As Fig. 5, embodiment one.
The connecting head of the present embodiment lining core 2 is square, the structural representation after connecting by molten solder between metal joint 1 and lining core 2.Annular welds junctor 3 has covered gap and the metal joint 1 between metal joint 1 and lining core 2 and has served as a contrast intersection between core 2.
As Fig. 6, embodiment two.
The connecting head of the present embodiment lining core 2 is taper, the structural representation after connecting by molten solder between metal joint 1 and lining core 2.Annular welds junctor 3 has covered intersection between metal joint 1 and lining core 2.
As Fig. 7, embodiment three.
The connecting head of the present embodiment lining core 2 is long taper, the structural representation after connecting by molten solder between metal joint 1 and lining core 2.Annular welds junctor 3 has covered gap and the metal joint 1 between metal joint 1 and lining core 2 and has served as a contrast intersection between core 2.
Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not breaking away under design concept prerequisite of the present invention; various modification and improvement that in related domain, common engineers and technicians make technological scheme of the present invention; all should fall into protection scope of the present invention, the technology contents that the present invention asks for protection all is documented in claims.
