Abstract
The utility model discloses a pressed end enclosure for boilers or pressure vessels. Commonly-used spherical or elliptic pressed end enclosures for boilers or pressure vessels are formed in a spinning mode or generally formed by hot-pressing single sheet billets through pressing dies; each end enclosure needs a corresponding puncher pin pull ring pressing die with the same specification in terms of diameter and thickness, and consequently boiler or pressure vessel manufacturing enterprises face with the problems that a large number of dies are needed, cost of the dies is high, manufacturing technologies are lacked and economic benefits are poor. The pressed end enclosure comprises a spherical or elliptic pressed end enclosure body (3), and the surface of one side or two sides of the end of the edge of the spherical or elliptic pressed end enclosure body is connected with a ring plate (1) through fillet welds (2). The method is used for forming end enclosures for boilers or pressure vessels in a pressing mode.
Description
technical field:
the utility model relates to a kind of boiler and pressure vessel pressing seal head.
background technology:
spherical or the oval pressing seal head that boiler and pressure vessel were conventional in the past, except adopting rotary press modelling, is all generally hot-forming by compacting tool set with single steel plate blank.The end socket of each diameter and thickness specification all need corresponding same specification drift draw ring compacting tool set.Cause boiler and pressure vessel manufacturers mould is too much, die cost is high, manufacturing technology is single, deficiency in economic performance.
utility model content:
the purpose of this utility model is to provide a kind of boiler and pressure vessel pressing seal head.
above-mentioned object realizes by following technical scheme:
a kind of boiler and pressure vessel pressing seal head, its composition comprises: spherical or oval pressing seal head, on the surface, marginal end portion one or both sides of described spherical or oval pressing seal head, described spherical or oval pressing seal head is connected by angle welding with ring flat-plate, between described ring flat-plate and described spherical or oval pressing seal head, is connected with space outerpace in the mode of ring flat-plate boring or angle welding local interruption, described angle welding is the angle welding that adopts manual electric arc welding or Lincoln weld, described ring flat-plate is the ring flat-plate that entirety or segmentation are manufactured.
beneficial effect:
1. the utility model has changed the pressing seal head such as spherical or oval that boiler and pressure vessel are in the past conventional and has only used the molded simple designs structure of single steel plate blank direct heat and dependence and the restriction of manufacturing process to drift and draw ring compacting tool set.By connect the novel pressing seal head special structure form of suitable thickness ring flat-plate with angle welding form at pressing seal head steel plate blank edge, between the different existing compacting tool set of specification and institute's press seal head, set up effective connection and adjusting.Have advantages of that even thickness, surface smoothing, welding job amount are little, easy to make, be conducive to guarantee seal head forming size and dimension at end socket edge welding equipment ring flat-plate, improve existing draw ring mould utilization rate, optimize pressing process, shorten the production cycle, increase economic efficiency.Simple in structure, technology novelty, practicality, advanced person, reliable.While being specially adapted to boiler and pressure vessel manufacturers compacting separate unit, small lot end socket, apply.
the utility model, by the special structure form for boiler and the novel pressing seal head of pressure vessel creativity and innovation, reaches and optimizes the manufacturing technology of pressing seal head, the object that improves existing compacting tool set utilization rate, reduces number of molds, reduces production costs, shortens the production cycle, increases economic efficiency.
the utility model is by the edge of the single steel plate blank of pressing seal head in the past, with angle welding form welding equipment ring flat-plate, partial thickening is carried out at straight flange position to pressing seal head edge, to reach inside and outside circle size and the thickness at effective adjusting pressing seal head straight flange position, make full use of existing compacting tool set.
accompanying drawing explanation:
accompanying drawing 1 is ring flat-plate structural representation of the present utility model while being arranged on lateral surface.
accompanying drawing 2 is the structural representations before ring flat-plate compacting of the present utility model.
accompanying drawing 3 is structural representations of SR358 × 52 novel ball end socket.
accompanying drawing 4 is ring flat-plate structural representations before ring flat-plate compacting of the present utility model while being arranged on medial surface.
accompanying drawing 5 is ring flat-plate structural representations before ring flat-plate compacting of the present utility model while being arranged on medial surface and lateral surface.
the specific embodiment:
embodiment 1:
a kind of boiler and pressure vessel pressing seal head, its composition comprises: spherical or oval pressing seal head, on the surface, marginal end portion one or both sides of described spherical or oval pressing seal head, described spherical or oval pressing seal head is connected by angle welding with ring flat-plate.
embodiment 2:
according to the boiler described in embodiment 1 and pressure vessel pressing seal head, between described ring flat-plate and described spherical or oval pressing seal head, be connected with space outerpace in the mode of ring flat-plate boring or angle welding local interruption, described angle welding is the angle welding that adopts manual electric arc welding or Lincoln weld, described ring flat-plate is the ring flat-plate that entirety or segmentation are manufactured.
embodiment 3:
described boiler and pressure vessel pressing seal head, the novel pressing seal head special structure form of boiler and pressure vessel, be included in the spherical and oval ring flat-plate that waits surface, end socket steel plate blank marginal end portion one or both sides to be connected suitable thickness and width with angle welding form of boiler and pressure vessel, ring flat-plate can entirety or segmentation manufacture, between ring flat-plate and steel plate blank, space is communicated with space outerpace in the mode of ring flat-plate boring or angle welding local interruption, prevents from forming enclosure space; Angle welding is to adopt the method welding such as manual electric arc welding or Lincoln weld to form; After end socket compacting, ring flat-plate appears at boiler and the Novel seal head straight flange position such as pressure vessel is spherical and oval is inside and outside or surfaces externally and internally, and is removed; By connect the ring flat-plate of suitable thickness in end socket blank steel plate edge, can effectively regulate head skirt position inside and outside circle size and thickness, facilitate the use existing compacting tool set.
embodiment 4:
described boiler and pressure vessel pressing seal head, compacting SR358 × 52 dome head still lacks plunger chip die, can regulate by increasing ring flat-plate mode at end socket inner surface, adopt novel compacting end enclosure structure form to make required SR358 × 52 end socket, ring flat-plate thickness is 8mm, head thickness is 52mm steel plate blank, SR350 × 60 compacting tool set.First, determine that SR358 × 52 dome head adopts Novel seal head project organization; Secondly, ring flat-plate thickness is got 8mm, 1/3 splicing, and with manual electric arc welding welding angle welding, ring flat-plate is connected with steel plate blank; Again, hot-forming to steel plate blank, after compacting, ring flat-plate and angle welding are removed, can obtain SR350 × 50 dome head; Finally, utilize existing SR350 × 60 draw ring mould, by pressing seal head version of the present utility model, with lower cost consumption, completed quickly and easily the making of SR358 × 52 dome heads.
