Abstract
The utility model provides a punch mould combination used for a boiler and the spherical head of a pressure vessel. The punch mould combination comprises a flat-base spherical punch body; a punch changeable embedded lump is mounted on the flat-base spherical punch body; and the flat base spherical punch body adopts a flat base on the mounting position and is matched with the embedded lump, so as to form a flat base spherical punch mould combination through a fastener. Bi-functional moulds with various shapes of spherical punch moulds of same specification are realized in the utility model. The punch mould combination has the characteristics of simple manufacture for embedded lump, reliable structure, low cost, easy assembly and disassembly and durability. The punch mould assembly is applicable to the manufacture of various medium wall boilers and the spherical head of the pressure vessel in bulk. The utility model has the major advantages that the enterprise mould quantity is reduced, considerable mould manufacture cost is saved, and the product manufacturing cycle is shortened.
Description
(1) technical field
The utility model relates to boiler and pressure vessel head manufacturing technology, is specifically related to the plunger chip die combination of dome head.
(2) background technology
At present, the such problem of boiler and pressure vessel head prior art ubiquity: the same size difformity (as at the bottom of the flat and ball point) dome head needs the drawback that obtain through refining plunger chip die respectively separately, cause enterprise's number of molds many, the die manufacturing cost height, production cycle is long, directly influences economic benefit of enterprises.
(3) summary of the invention
The purpose of this utility model is to provide a kind of enterprise's number of molds that reduces, and reduces considerable die manufacturing cost, shortens the production cycle, obviously improves the plunger chip die combination that is used for boiler and pressure vessel dome head of business economic benefit.
The purpose of this utility model is achieved in that it comprises flat spherical drift body, on flat spherical drift body, be equipped with one and can carry out inserting of drift conversion, on the flat spherical drift body in installation place is flat, cooperates and forms flat spherical plunger chip die combination by securing member with inserting.
The utility model also has some technical characterictics like this:
1, described insert and flat spherical drift body cooperation place is flat, outer rim is hemispherical;
2, described securing member is a sunk screw;
3, described securing member is plug welding.
The utility model is by installing block-shaped appropriate, a material plunger chip die combination light and handy, cheap, simple in structure, that insert a kind of reliably on an existing flat spherical drift body, make spherical plunger chip die at the bottom of the identical new ball of the needed specification of another part, the backward practice that the difform two kinds of spherical drifts of same size that formed since having avoided over a long period of time need be obtained through refining plunger chip die separately.Also can may carry out flat processing on the spherical drift body at the bottom of the existing ball under the situation conversely, this drift become by the flat dome head of same specification add spherical drift assembling die at the bottom of the ball of inserting, do not influencing under the former spherical end socket plunger chip die operating position, insert by dismounting, obtain the identical new flat spherical plunger chip die of the needed specification of another part.Therefore, the utility model has realized utilizing a kind of spherical plunger chip die body to make the spherical plunger chip die of two kinds of specifications by the conversion of inserting.The utility model has been realized " mould is dual-purpose " under the prerequisite that guarantees the product stamping quality, reduced enterprise's number of molds, has reduced considerable die manufacturing cost, has shortened the product manufacturing cycle, has obviously improved economic benefit of enterprises.
Flat spherical drift body can a kind of needed flat dome head of punching press; This body is by coupling together with inserting with the securing member of some, can form spherical drift at the bottom of the ball of another kind of same size, again can the another kind of needed ball of punching press at the bottom of dome head.Formed the plunger chip die combination technique of " mould is dual-purpose " of the spherical plunger chip die body of a kind of specification.
Invention effect of the present utility model has: the plunger chip die body adds the plunger chip die combination technique of inserting, and has realized " mould is dual-purpose " of the spherical plunger chip die of same size difformity first.Be characterized in inserting make simple, reliable in structure, with low cost, mounting or dismounting are easy, durable in use.The utility model is fit to the middle heavy wall boiler of various batches and the manufacturing of pressure vessel dome head.Major advantage is to reduce enterprise's number of molds, saves considerable die manufacturing cost, shortens the product manufacturing cycle, obviously improves economic benefit of enterprises.
(4) description of drawings
Fig. 1 is a product structure schematic diagram of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Embodiment 1: present embodiment comprises flat spherical drift body 1, what the conversion of can inserting was installed on flat spherical drift body 1 inserts 2, on the flat spherical drift body in installation place is flat, and the match grinding contoured surface also forms flat spherical plunger chip die combination by securing member 3 with inserting.In conjunction with Fig. 1, insert 2 with flat spherical drift body 1 cooperation place be flat, outer rim is hemispherical, it transits to flat spherical drift body outer rim and forms flat spherical drift, flat-bottom punch is connected with the screw of inserting in the present embodiment, processing technology is:
The design of (1), inserting;
(2), the processing of the profile lathing inserted, with the tapping of flat bottom cover drilling;
(3), insert and flat-bottom punch match grinding contoured surface;
(4), insert and be connected with flat-bottom punch by sunk screw.
Embodiment 2: present embodiment basic structure is with embodiment 1, and difference is flat-bottom punch and being welded to connect of inserting, and processing technology is:
The design of (1), inserting;
The profile lathing processing of (2), inserting, processing plug welding hole;
(3), insert and flat-bottom punch match grinding contoured surface;
(4), insert and be connected with flat-bottom punch by plug welding.
Wherein, first kind of scheme mounting or dismounting is more flexible; First kind of scheme relatively is fit to not remove for a long time use.
Claims (4)
1, a kind of plunger chip die combination that is used for boiler and pressure vessel dome head, it comprises flat spherical drift body, it is characterized in that on flat spherical drift body, being equipped with one and can carry out inserting of drift conversion, on the flat spherical drift body in installation place is flat, cooperates and forms flat spherical plunger chip die combination by securing member with inserting.
2, a kind of plunger chip die combination that is used for boiler and pressure vessel dome head according to claim 1 is characterized in that described insert and flat spherical drift body cooperation place is flat, and outer rim is hemispherical.
