Abstract
The utility model discloses a forming mold for pressing a semicircular tube, which is characterized in that the mold comprises a lower mold, wherein the lower mold is connected with an upper mold by an inner ring; and an outer ring is arranged at the periphery of the inner ring. The forming mold has the characteristics of low material wastage, high working efficiency, low welding combination requirements, simple structure and high material utilization ratio.
Description
Technical field
The utility model relates to a kind of mould of compacting half endless tube moulding, belongs to semi-ring pipe shaping mould field.
Background technology
In certain chemical engineering project, because product structure adopts a kind of ring-type half endless tube.Its material is expensive incoloy825, in the past basic adopt be divided into up and down two halves sheet compacting after assembly welding become endless tube, first with plate circlewise under the material, suppress again, to waste of material large (main ring flat-plate stock utilization is low) during compacting; The welding combination is had relatively high expectations.
Summary of the invention
The purpose of this utility model is to solve that waste of material is large, the welding combination requires high problem, the mould that provide that a kind of spillage of material is few, high efficiency, welding combination requires the compacting low, simple in structure, that stock utilization is high half endless tube moulding.
In order to achieve the above object, the utility model provides a kind of mould of compacting half endless tube moulding, it is characterized in that comprise counterdie, counterdie is connected with patrix by inner ring, the outer outer ring that is arranged with of inner ring.
Preferably, described inner ring is divided at least 3 equal segments.
Preferably, form the cavity body of mould of sealing between the upper projection on the lower convexity on the described counterdie, the patrix and the inner ring, closely be connected between lower convexity and the upper projection.
Preferably, described lower convexity is identical with the size shape of upper projection.
The utility model adopts built up cavity, reaches up and down simultaneously flange moulding of both sides, realizes once compressingly, is convenient in demoulding reliably by the inner ring equal portions being divided, being made.Mould of the present utility model, simple in structure, applicability is stronger, and pressing process is easy, reduces the rear welding combination of in the past burst compacting difficulty, improves processing work efficient; Reduce the raw material loss, improve stock utilization (utilization rate of raw materials 13% is increased to 98%), in the past burst compacting, blank is circular sheet material, interior ring center material can't be utilized substantially, now can be with rectangularity under the sheet material, again by the synthetic tubular blank of soldering group, reduce welding combination requirement, greatly improve stock utilization.
Description of drawings
Fig. 1 is a kind of pressing structure schematic diagram of mould of compacting half endless tube moulding.
Description of reference numerals:
1 is inner ring, and 2 is counterdie, and 3 is the outer ring, and 4 is blank, and 5 is patrix, and 6 is lower convexity, and 7 is upper projection, and 8 is cavity body of mould.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
Embodiment 1
As shown in Figure 1, be a kind of pressing structure schematic diagram of suppressing the mould of half endless tube moulding.A kind of mould of compacting half endless tube moulding, counterdie 2 is connected with patrix 5 by inner ring 1, and the outer race of inner ring 1 has outer ring 3.
Inner ring 1 is divided at least 3 equal segments, forms the cavity body of mould 8 of sealing between upper protruding 7 and the inner ring 1 on the lower convexity 6 on the counterdie 2, the patrix 5, closely is connected between the lower convexity 6 and upper protruding 7, and lower convexity 6 is identical with upper protruding 7 size shape.
When suppressing half endless tube moulding, its processing method may further comprise the steps: first inner ring 1 is enclosed within on the lower convexity 6 on the counterdie 2; Again outer ring 3 is trapped among inner ring 1 outside, plays fixation; Be that rectangular blank rolls into tubular with cross section, and weld appropriate longitudinal joint, form the blank 4 of tubulose, wherein, the internal diameter of blank 4 is identical with the external diameter of lower convexity 6 tops, upper protruding 7 bottoms, and the thickness of blank 4 is big or small identical with cavity body of mould 8, and the height of blank 4 is greater than the height of inner ring 1; Ready blank 4 is put into lower convexity 6 and inner ring 1 formed groove; With the center of upper protruding 7 bottom aligning blank 4, push by 5 pairs of blanks 4 of patrix, until patrix 5 is pressed onto on the inner ring 1 fully, so that the up and down both sides of blank 4 while flange; Successively patrix 5 and outer ring 3 are removed, the inner ring 1 that will be divided into subsequently equal portions removes one by one, removes at last counterdie 2, and whole pressing process finishes, and remaining is half compressing endless tube.
The utility model adopts built up cavity, reaches up and down simultaneously flange moulding of both sides, realizes once compressingly, is convenient in demoulding reliably by the inner ring equal portions being divided, being made.
