Abstract
The utility model discloses a rotary intermediate mould used for processing an expansion joint. The rotary intermediate mould comprises an inner mould and an outer mould, wherein the outer mould is an integral outer mould; an outer mould bump is arranged on the inner hole wall of the outer mould; the inner mould is composed of two inner half moulds; the outer wall of each inner half mould is provided with an inner mould groove matching with the outer mould bump. The rotary intermediate mould used for processing the expansion joint has the beneficial effects that: the outer mould of the intermediate mould is of an integral structure, the inner mould is composed of two semi-ring-shaped inner half moulds, the inner mould groove and the outer mould bump are aligned to each other when in use, the inner half moulds after being assembled are rotated for 45 degrees to be sleeved on a pipe blank, and after the pressing is finished, the outer mould is rotated for 45 degrees and then the inner half moulds are taken off to finish the whole pressing process. The rotary intermediate mould used for processing the expansion joint has the advantages of being simple in structure, convenient to assemble and disassemble, long in service life, and high in size precision of produced products.
Description
Technical field
The utility model relates to special metal part processing technique field, especially relates to a kind of expansion joint processing rotary type intermediate die.
Background technology
Expansion joint is called telescopic joint or corrugated expansion joint traditionally, that limited dilatation by a kind of like this flexible structure element of expansion joint absorbs the change in size that pipeline, conduit or container produce due to the reason such as expand with heat and contract with cold, a kind of for compensating element.Different according to material therefor, can be divided into type metal expansion joint and non-metal expansion joint.When the crest of pressed metal expansion joint, intermediate die need to be installed in the middle of adjacent two crest locations.The expansion joint of different materials, different size, corresponding intermediate die requires different.Expansion joint size is larger, more require intermediate die easy to removal and installation, and in prior art, monoblock type intermediate die is difficult to meet this requirement.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, provide a kind of mounting or dismounting four to open intermediate die easily, interior half module is arranged in external mold by internal mold groove, the technical scheme adopting is: a kind of expansion joint processing rotary type intermediate die, comprise internal mold and external mold, it is characterized in that: described external mold is monoblock type external mold, is provided with external mold projection on the inner hole wall of described external mold; Described internal mold consists of two interior half modules, is provided with the internal mold groove matching with external mold projection on the outer wall of described interior half module.
Technical characterictic of the present utility model also has: described external mold projection is four, is evenly distributed on the inner hole wall of external mold.
The beneficial effects of the utility model are: the external mold of this intermediate die is monolithic construction, and internal mold consists of half module in two semicirculars, during use, internal mold groove is alignd with external mold projection, after assembling, interior half module being rotated to 45 ° is sleeved on pipe, after having suppressed, external mold takes off interior half module after rotating 45 °, and whole compacting finishes.The utlity model has advantage simple in structure, to install and remove facility, long service life, the product size precision height of doing.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is cutaway views of accompanying drawing 1, and accompanying drawing 3 is cast outer mold structure schematic diagrames, and accompanying drawing 4 is interior half module structural representations, wherein, the 1st, external mold, the 2nd, interior half module, the 3rd, external mold projection, the 4th, internal mold groove.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.The utility model discloses a kind of expansion joint processing and use rotary type intermediate die, comprise internal mold and external mold 1, wherein external mold 1 is monoblock type external mold, is provided with external mold projection 3 on the inner hole wall of external mold 1.Internal mold consists of two interior half modules 2, is provided with the internal mold groove 4 matching with external mold projection 3 on the outer wall of interior half module 2.
In the present embodiment, external mold projection is four, is evenly distributed on the inner hole wall of external mold 1.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
Claims (2)
1. a rotary type intermediate die is used in expansion joint processing, comprises internal mold and external mold, it is characterized in that: described external mold is monoblock type external mold, is provided with external mold projection on the inner hole wall of described external mold; Described internal mold consists of two interior half modules, is provided with the internal mold groove matching with external mold projection on the outer wall of described interior half module.
2. according to expansion joint processing claimed in claim 1, use rotary type intermediate die, it is characterized in that: described external mold projection is four, is evenly distributed on the inner hole wall of external mold.
