Abstract
The utility model discloses a tooling for processing an expansion joint on a pipe fitting. The tooling comprises an upper mould and a lower mould which are used in a buckled manner, wherein a forming groove is formed between the upper mould and the lower mould which are buckled with each other; an expansion groove is arranged on the forming groove; after being buckled with each other, the upper mould and the lower mould are sleeved by an integral protection mold comprising a tapered inner chamber; and the wall of the tapered inner chamber of the integral type protection mold and the outer walls of the upper and the lower moulds form a conical surface and are jointed with each other. The tooling has the advantages that the structure is simple; the swell forming of the expansion joint on the pipe fitting is greatly facilitated; the processing cost is reduced; and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of frock of on pipe fitting, processing used for expansion joint.
Background technology
In order to satisfy the mechanically needs of special use; Usually expansion joint need be set on pipe fitting, a kind of method commonly used is through turning processing, and the pipe fitting that has strengthened wall thickness is carried out whole turning; Unwanted local turning is fallen, and the place of reservation just forms bulge shape expansion joint.Yet this turning method for processing need strengthen the wall thickness of whole pipe fitting, and so not only waste material has improved processing cost, and the position of differential expansion difficulty carry out turning, waste time and energy, production efficiency is low.
The utility model content
The problem that the utility model need solve be: provide a kind of simple in structure, can make things convenient for expansion joint expansion molding on the pipe fitting greatly a kind of on pipe fitting the frock of processing used for expansion joint.
For addressing the above problem; The technical scheme that the utility model adopts is: a kind of frock of on pipe fitting, processing used for expansion joint; The upper die and lower die that comprise involutory use form forming tank between the upper die and lower die after involutory, and described forming tank is provided with expansion slot; Upper die and lower die after involutory are set with the monoblock type protection mould of band conical internal cavity outward, are the conical surface between the conical internal cavity wall of described monoblock type protection mould and the outer wall of upper die and lower die and fit each other.
Further, aforesaid expansion tube is used frock, and wherein, described upper die and lower die are upper and lower Hough mould.
The utility model has the advantages that: simple in structure, greatly facilitate the expansion molding of expansion joint on the pipe fitting, reduced processing cost, improved production efficiency.
Description of drawings
Fig. 1 is the described a kind of structural representation of on pipe fitting, processing the frock of used for expansion joint of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1; A kind of frock of on pipe fitting, processing used for expansion joint; The last Hough mould 1 and following Hough mould 2 that comprise involutory use, formation forming tank 3 between last Hough mould 1 after involutory and the following Hough mould 2 is provided with expansion slot 31 on the described forming tank 3; Last Hough mould 1 after involutory and the following Hough mould 2 outer monoblock type protection moulds 4 that are set with the band conical internal cavity are the conical surface between the conical internal cavity wall of described monoblock type protection mould 4 and the outer wall of last Hough mould 1 and following Hough mould 2 and fit each other.
The operation principle of the utility model is following: fill in monoblock type after the last Hough mould 1 that the pipe fitting 5 that needs the processing expansion joint will be housed and following Hough mould 2 are involutory and protect in the inner chamber of mould 4; The outer wall of Hough mould 1 and following Hough mould 2 and the internal chamber wall of monoblock type protection mould 4 are fitted each other; Then the hydraulic expanding tube device is put into pipe fitting 5; The hydraulic expanding tube device produces high pressure; Pipe fitting 5 is expanded at the position of expansion slot 31 heave and form expansion joint;, goes up by pipe fitting 5 Hough mould 1 and following Hough mould 2 stressed also outwards expansions when expanding; And fit each other owing to be the conical surface between the outer wall of the internal chamber wall of monoblock type protection mould 4 and last Hough mould 1 and following Hough mould 2, promptly monoblock type protects the inner chamber of mould 4 to be tapered to an other end by an end, and the outer wall of the mould of Hough up and down after involutory also is an end to the tapered shape of the other end; When upper and lower Hough mould receive the back of expanding when outwards expanding its outer wall will protect the mutual swelling of conical internal cavity wall of mould 4 with monoblock type, between monoblock type protection mould 4 and last Hough mould 1 and the following Hough mould 2 relative slip can not take place.In the process that pipe fitting expands, monoblock type protection mould 4 has born the bulbs of pressure, has guaranteed the normal expansion at the position of processing expansion joint on the pipe fitting 5.Treat that pipe fitting 5 expansions finish, only need upper and lower Hough mould knocked out from monoblock type protection mould 4 and can obtain the pipe fitting 5 that expand tube finishes with the method for knocking.
Claims (2)
- One kind on pipe fitting processing used for expansion joint frock; It is characterized in that: the upper die and lower die that comprise involutory use; Form forming tank between the upper die and lower die after involutory; Described forming tank is provided with expansion slot, and the upper die and lower die after involutory are set with the monoblock type protection mould of band conical internal cavity outward, is the conical surface between the conical internal cavity wall of described monoblock type protection mould and the outer wall of upper die and lower die and fits each other.
- 2. a kind of frock of on pipe fitting, processing used for expansion joint according to claim 1, it is characterized in that: described upper die and lower die are upper and lower Hough mould.
