Background technology:

At present, the dome head that boiler and pressure vessel are commonly used except rotary press modelling, generally all is compressing with whole spherical plunger chip die.The dome head of same nominal diameter and ellipse head need to obtain through refining separately respectively the solid punch mould to be suppressed, and causes boiler and pressure vessel head manufacturing enterprise plunger chip die is too much, die cost is high, deficiency in economic performance.

Summary of the invention:

The purpose of this utility model provides a kind of optimization plunger chip die that can reach and designs, improves existing plunger chip die utilization rate, the consumption of minimizing plunger chip die, reduction manufacturing cost, the boiler of increasing economic efficiency and pressure vessel sphere and the spherical plunger chip die of oval dual-purpose NEW TYPE OF COMPOSITE.

Above-mentioned purpose realizes by following technical scheme:

The spherical plunger chip die of the spherical and oval dual-purpose NEW TYPE OF COMPOSITE of a kind of boiler and pressure vessel, its composition comprises: oval plunger chip die, combination die, described oval plunger chip die has oblong surface or convex surface, has concave surface above the described combination die, described oblong surface or convex surface connect described concave surface, and described oval plunger chip die connects described combination die and is welded to connect described combination die with the fastening or described oval plunger chip die of bolt fastener.

Have convex surface below the spherical plunger chip die of the spherical and oval dual-purpose NEW TYPE OF COMPOSITE of described boiler and pressure vessel, described combination die, described convex surface forms the spherical surface of complex spherical plunger chip die.

Beneficial effect:

1. the special structure form of the spherical and oval dual-purpose spherical plunger chip die of NEW TYPE OF COMPOSITE of the utility model reaches the purpose of optimizing the plunger chip die design, improving existing plunger chip die utilization rate, reduce plunger chip die consumption, reduce manufacturing cost, increase economic efficiency.

2. the required integral spherical plunger chip die of compacting dome head that the utility model will be in the past be made into oval plunger chip die with same specification, by bolt fastener or weld seam connect insert after, form spherical and oval dual-purpose NEW TYPE OF COMPOSITE sphere plunger chip die version; Reach the spherical drift project organization of optimization, take full advantage of existing plunger chip die, reduced material consumption and cost, improved the economic benefit of boiler and pressure vessel head manufacturing enterprise.

The utility model has changed common boiler of past and pressure vessels spherical seal-head uses single integrally-built plunger chip die to bring the large deficiency of mould consumable material; With needed in the past independent spherical plunger chip die structure innovation made in one piece for same specification, existing or newly obtain through refining oval plunger chip die, by bolt fastener or the weld seam connection rear formation compound punch mould structure of inserting.

The oval plunger chip die that comprises same specification in the spherical plunger chip die of the utility model, both available existing oval plunger chip die was wherein suppressed ellipse head, and the compacting dome head also can combine; Otherwise, by the spherical compound punch mould that the application newly obtains through refining, both can suppress dome head, also can with oval plunger chip die compacting ellipse head wherein, realize that a mould is dual-purpose.

Complex spherical plunger chip die of the present utility model is the oval plunger chip die of existing or the same specification of newly the obtaining through refining overwhelming majority as this mould, but Effective Raise plunger chip die utilization rate, reduces the plunger chip die manufacturing cost, reduces enterprise's mould consumption, increases economic efficiency.

The utility model technology is novel, practical, advanced, reliable; Simple in structure, easy to make, easy disassembling, durable in use, be convenient to select.

The utility model utilizes the oval plunger chip die of existing Dn700, newly-increased insert and the bolt fastener preparation has been finished and needed the spherical plunger chip die of SR350 made in one piece in the past, and the about 1450kg of cutting down the consumption of raw materials, 81% has obviously reduced the mould manufacturing expense.
