Abstract
The invention discloses a forming die for compression moulding a semi-circular pipe, which comprises a lower die, wherein the lower die is connected with an upper die through inner rings, and an outer ring is arranged at the peripheries of the inner rings. A processing method of the forming die for compression moulding the semi-circular pipe comprises the following steps that step 1, the inner rings are sleeved at a lower projection on the lower die; step 2, then, the outer ring surrounds the outer parts of the inner rings, and plays the role of fixing; step 3, a blank with a rectangular cross section is coiled into a barrel shape, and the two ends of the blank are welded together to form the blank of the semi-circular pipe; step 4, the prepared blank is put in a groove which is formed by the lower projection and the inner rings; step 5, the bottom end of an upper projection is aligned to the center of the blank until the upper die is completely compressed onto the inner rings; and step six, the upper die and the outer ring are sequentially removed, then, the inner rings which are dividedly equally are removed one by one, so the semi-circular pipe which is compression moulded is obtained. The die has the characteristics of less material consumption, high working efficiency, low requirements on welding combination, simple structure and high material utilization rate.
Description
Technical field
The present invention relates to the shaping mould of a kind of compacting half endless tube and processing method, belong 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 upper and lower two half compactings after assembly welding become endless tube, first by plate circlewise under material during compacting, then suppress, to waste of material comparatively large (main ring flat-plate stock utilization is low); Welding combination requires higher.
Summary of the invention
The object of the invention is to solve that waste of material is large, welding combination requires high problem, provide that a kind of spillage of material is few, operating efficiency is high, welding combination requires the mould that low, that structure is simple, stock utilization is high compacting half endless tube is shaping and processing method.
In order to achieve the above object, the invention provides the mould that a kind of compacting half endless tube is shaping, it is characterized in that, comprise counterdie, counterdie is connected with patrix by inner ring, and the outer of inner ring is arranged with outer ring.
Preferably, described inner ring is divided at least 3 equal segments.
Preferably, the lower convexity on described counterdie, the projection on patrix and form closed cavity body of mould between inner ring, compact siro spinning technology between lower convexity and projection.
Preferably, described lower convexity is identical with the size shape of projection.
Adopt the processing method that compacting half endless tube as above-mentioned mould is shaping, it is characterized in that, comprise the following steps:
Step one, is enclosed within the lower convexity on counterdie by inner ring;
Step 2, then outer ring is trapped among outside inner ring, play fixation;
Step 3, is that rectangular blank rolls into tubular by cross section, and welds appropriate longitudinal joint, forms the blank of tubulose;
Step 4, puts into the groove that lower convexity and inner ring are formed by ready blank;
Step 5, is aimed at the center of blank, is extruded by patrix to blank by the bottom of projection, until be pressed onto completely on inner ring by patrix, make the flange simultaneously of both sides up and down of blank;
Step 6, removes patrix and outer ring successively, is removed one by one by the inner ring being divided into equal portions subsequently, finally removes counterdie, and whole pressing process terminates, and namely obtains half compressing endless tube.
Preferably, the internal diameter of the blank in described step 4 is identical with the external diameter of lower convexity top, projection bottom, and the thickness of blank is identical with the size of cavity body of mould, and the height of blank is greater than the height of inner ring.
The present invention adopts built up cavity, and flange is shaping simultaneously to reach upper and lower both sides, realizes once compressing, by being divided by inner ring equal portions, makes to be convenient in demoulding reliably.Mould of the present invention, structure is simple, adopts drawing method of the present invention, and applicability is comparatively strong, and pressing process is easy, welds combination difficulty, improve processing work efficiency after reducing burst compacting in the past; Reduce raw material loss, improve stock utilization (utilization rate of raw materials 13% is increased to 98%), burst compacting in the past, blank is circular sheet material, and inner ring center material cannot utilize substantially, and existing method can by rectangularity under sheet material, again by soldering group synthesis tubular blank, reducing welding combination requirement, greatly improve stock utilization, is a kind of forming method sheet material preferably.
Accompanying drawing explanation
Fig. 1 is a kind of pressing structure schematic diagram suppressing the shaping mould of half endless tube.
Description of reference numerals:
1 is inner ring, and 2 is counterdie, and 3 is outer ring, and 4 is blank, and 5 is patrix, and 6 is lower convexity, and 7 is projection, and 8 is cavity body of mould.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.
Embodiment 1
As shown in Figure 1, be a kind of pressing structure schematic diagram suppressing the shaping mould of half endless tube.The mould that compacting half endless tube is shaping, 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, the lower convexity 6 on counterdie 2, the projection 7 on patrix 5 and form closed cavity body of mould 8, compact siro spinning technology between lower convexity 6 and projection 7 between inner ring 1, and lower convexity 6 is identical with the size shape of projection 7.
Suppress half endless tube shaping time, its processing method, comprises the following steps: be first enclosed within by inner ring 1 on the lower convexity 6 on counterdie 2; Again outer ring 3 is trapped among outside inner ring 1, plays fixation; Be that rectangular blank rolls into tubular by 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 top, projection 7 bottom, and the thickness of blank 4 is identical with the size of 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 the groove that lower convexity 6 is formed with inner ring 1; The bottom of projection 7 is aimed at the center of blank 4, extruded by patrix 5 pairs of blanks 4, until be pressed onto completely on inner ring 1 by patrix 5, make the flange simultaneously of both sides up and down of blank 4; Patrix 5 and outer ring 3 are removed successively, removed one by one by the inner ring 1 being divided into equal portions subsequently, finally remove counterdie 2, whole pressing process terminates, and remaining is half compressing endless tube.
The present invention adopts built up cavity, and flange is shaping simultaneously to reach upper and lower both sides, realizes once compressing, by being divided by inner ring equal portions, makes to be convenient in demoulding reliably.
