Abstract
The utility model relates to a composite oval punch die for a boiler and a pressure container. At present, oval end sockets commonly used by the boiler and the pressure container are often formed by an integral oval punch die in a pressing mode besides spinning forming, spherical end sockets and oval end sockets of the same nominal diameter are required to be pressed through an integral punch die singly extracted respectively, and the problems of too many punch dies, high die cost and poor economical benefit are caused to enterprises manufacturing the end sockets of the boiler and the pressure container. The punch die comprises an integral spherical punch die (1) and an insert die (2). One end of the integral spherical punch die is provided with a spherical surface, one end of the insert die is provided with a recessed face matched with the spherical surface, the other end of the insert die is provided with an oval protruding face, the integral spherical punch die is connected with the insert die, and the integral spherical punch die and the insert die has identical nominal diameter. The die is used for die pressing.
Description
technical field:
the utility model relates to a kind of boiler and the compound oval plunger chip die of pressure vessel.
background technology:
at present, the ellipse head that boiler and pressure vessel are conventional, except rotary press modelling, is generally all compressing with whole oval plunger chip die.The dome head of same nominal diameter and ellipse head need to obtain through refining separately respectively solid punch mould to be suppressed, and sees Fig. 1 and Fig. 2.Cause boiler and pressure vessel head manufacturing enterprise plunger chip die is too much, die cost is high, deficiency in economic performance.
utility model content:
the purpose of this utility model is to provide a kind of boiler and the compound oval plunger chip die of pressure vessel.
above-mentioned object realizes by following technical scheme:
the compound oval plunger chip die of a kind of boiler and pressure vessel, its composition comprises: integral spherical plunger chip die, combination die, described integral spherical plunger chip die one end has spherical surface, described combination die one end has the concave surface matching with described spherical surface, the other end of described combination die has oval convex surface, described integral spherical plunger chip die is connected with described combination die, and described integral spherical plunger chip die has identical nominal diameter with described combination die.
beneficial effect:
1. the utility model takes full advantage of the integral spherical plunger chip die of existing same specification: both available spherical plunger chip die compacting dome heads, also can, by increasing the combination die of the identical nominal diameter compacting ellipse head that combines, realize a mould dual-purpose.Spherical plunger chip die as compound oval drift exhausted most, can effectively improve existing plunger chip die utilization rate, reduce plunger chip die manufacturing cost, reduce enterprise's mould consumption, increase economic efficiency.
the utility model is applicable to boiler and the application of pressure vessel head manufacturing enterprise, is especially applicable to the application of solid punch mould compacting diameter Dn300～4000mm end socket.
compound oval drift design of the present utility model has changed past boiler and pressure vessel ellipse head is used single integrally-built oval plunger chip die to suppress the large deficiency of mould consumable material of bringing.
when integral spherical plunger chip die is connected by bolt fastener with combination die, the utility model is suitable for often assembling and dismounting of needs, the occasion of replaceable mould shape repeatedly; When integral spherical plunger chip die is connected by weld seam with combination die, the utility model is suitable for not needing frequent assembly and disassembly and the occasion of replaceable mould shape repeatedly not.The utility model is simple in structure, easy to make, easy disassembling, durable in use, be convenient to select.

the specific embodiment:
embodiment 1:
the compound oval plunger chip die of a kind of boiler and pressure vessel, its composition comprises: integral spherical plunger chip die 1, combination die 2, described integral spherical plunger chip die one end has spherical surface, described combination die one end has the concave surface matching with described spherical surface, the other end of described combination die has oval convex surface, described integral spherical plunger chip die is connected with described combination die, and described integral spherical plunger chip die has identical nominal diameter with described combination die.
embodiment 2:
according to the boiler described in embodiment 1 and the compound oval plunger chip die of pressure vessel, described integral spherical plunger chip die can be connected by bolt fastener 3 with described combination die, and described integral spherical plunger chip die also can be connected by weld seam 4 with described combination die.
embodiment 3:
the compound oval plunger chip die of described boiler and pressure vessel, utilizes the spherical plunger chip die of existing SR250 (or Dn 500) to prepare the oval plunger chip die of Dn500.According to the utility model, the oval plunger chip die of Dn500 can adopt compound oval plunger chip die version, sees Fig. 7.Dn500 is compound, and oval plunger chip die manufacture process is:
(1) according to the spherical plunger chip die of existing SR250, the design compound oval plunger chip die Dn500 combination die of Dn500 and bolt fastener;
(2) obtain through refining newly-increased Dn500 combination die and bolt fastener.Require combination die and the spherical plunger chip die sphere of SR250 will be joined car, note closes; Screw is joined brill.Combination die adopts vertical numerical controlled lathe to be processed as suitable;
(3) the spherical plunger chip die of assembling SR250, Dn500 combination die, bolt fastener, prepare the compound oval plunger chip die of required Dn500.
(4) the utility model utilizes the spherical plunger chip die of existing SR250, has increased less Dn500 combination die and the bolt fastener of consumable material newly, prepared and needed the compound oval plunger chip die of Dn500 that consumable material made in one piece is larger in the past, obviously reduced material consumption and mould manufacturing expense.
Claims (1)
1. a boiler and the compound oval plunger chip die of pressure vessel, its composition comprises: integral spherical plunger chip die, combination die, it is characterized in that: described integral spherical plunger chip die one end has spherical surface, described combination die one end has the concave surface matching with described spherical surface, the other end of described combination die has oval convex surface, described integral spherical plunger chip die is connected with described combination die, and described integral spherical plunger chip die has identical nominal diameter with described combination die.
