Abstract
The invention discloses a nodular cast iron pipe die. The nodular cast iron pipe die comprises a pipe die body, the pipe die body is composed of a 6-meter pipe body section, a diversion section connected with the pipe body section, and a jack sleeve on the inner left side of the pipe body section; the right end of the jack sleeve and the pipe body section are welded with a surfacing section; and the total length of the jack length and the surfacing section is 0.3 meter. By fixing the jack sleeve inside the pipe die with an original effective length of 6 meters, the nodular cast iron pipe die can produce nodular cast iron pipes with an effective length of 5.7 meters under the condition of keeping the integral length of the pipe die unchanged; when not needing the 5.7-meter nodular cast iron pipes, an operator simply needs to remove the jack sleeve and to produce nodular cast iron pipes with an effective length of 6 meters, wherein the jack sleeve is reusable.
Description
Technical field
The present invention relates to a kind of centrifugal process and produce the effective pipe die of spheroidal graphite cast-iron, the pipe die that the centrifugal process production ductile iron pipe that particularly a kind of pipe shaft effective length can adapt to pallet loading uses.
Background technology
The standard effective length of the common ductile iron pipe that current domestic centrifugal process is produced is 6 meters, and the centrifuge that production process uses and pipe die are also design according to the such pipe of production and be equipped with.But ductile iron pipe for export mainly adopts maritime container transportation, in order to adapt to pallet loading, be mainly in the industry that the pipe of 6 meters changes 5.7 meters into by effective length.
At present usually adopt two kinds of modes of production: a kind of be production effective length is after the ductile iron pipe of 6 meters, reaches 5.7 meters through cutting.This mode adds manufacturing cost, causes very large waste; Two kinds is order short tube mould to make its production effective length be the ductile iron pipe of 5.7 meters, short tube mould must be adapted to like this to production equipment transformations such as centrifuges, and this mode cost is very high, considerably increase production cost, simultaneously when there is no this order, short tube mould leaves unused always, causes very large waste.
Summary of the invention
The technical problem to be solved in the present invention is: provide the ductile iron pipe pipe die that a kind of casting length can change, thus meets the casting requirement of 6 meters and 5.7 meters ductile iron pipes simultaneously.
In order to solve the problems of the technologies described above, ductile iron pipe pipe die of the present invention comprises pipe die body, it is the pipe shaft section 5 of 6 meters and the diversion section 1 that is connected with pipe shaft section that described pipe die body includes length, also include the socket cover 2 being arranged on left side in pipe shaft section, described socket overlaps 2 right-hand members and pipe shaft section 5 is welded with built-up welding section 3, and described socket cover 2 is 0.3 meter with the total length of built-up welding section 3.
In order to a small amount of remaining molten iron being discharged, described socket cover 2 is the cylinder of hollow.
In order to meet the casting requirement of ductile iron pipe, the right-hand member of described built-up welding section 3 is provided with the chamfering 4 consistent with ductile iron pipe socket.
The invention has the beneficial effects as follows: the pipe die internal fixtion socket cover of the present invention by former effective length being 6 meters, can production effective length be just the ductile iron pipe of 5.7 meters when pipe die entire length remains unchanged, facilitate pallet loading, be conducive to organization of production, stopped the unnecessary waste because Pipe Cutting causes, need not carry out transformation to centrifuge can complete simultaneously; In addition, when not needing the pipe of production 5.7 meters, only need socket cover to remove just to may be used for the ductile iron pipe that production effective length is 6 meters, socket cover can also be reused, and transformation and the recovery of this mechanism are simple, improve pipe die service efficiency.

Fig. 1 is structural representation of the present invention;
In figure: 1, diversion section, 2, socket cover, 3, built-up welding section, 4, chamfering, 5, pipe shaft section.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 shows a kind of detailed description of the invention of ductile iron pipe pipe die of the present invention.As shown in Figure 1, ductile iron pipe pipe die of the present invention comprises pipe die body, and as shown in Figure 1, pipe die body includes that length is the pipe shaft section 5 of 6 meters and the diversion section 1 be connected with pipe shaft section, the socket being arranged on left side in pipe shaft section 5 overlaps 2.As shown in Figure 1, socket overlaps 2 right-hand members and pipe shaft section 5 is welded with built-up welding section 3, the effect of built-up welding section 3 is mainly fixed on socket cover 2 in pipe shaft section 5, prevent socket from overlapping between the outer surface of 2 and the inner surface of pipe shaft section 5 simultaneously and there is gap, ductile iron pipe will be caused to extract if there is molten iron to enter.Requirement simultaneously in order to meet 5.7 meters, described socket cover 2 is 0.3 meter with the total length of built-up welding section 3.In order to be discharged by unnecessary molten iron, socket cover 2 is the cylinder of hollow.In order to meet the casting shape need of ductile iron pipe, the right-hand member of built-up welding section 3 is provided with the chamfering 4 consistent with ductile iron pipe socket.When needing the ductile iron pipe of casting 5.7 meters, socket cover 2 is needed to put into pipe shaft section 5, socket overlaps 2 left ends to be fixed near the left end of pipe shaft section 5, socket overlaps 2 right-hand members and pipe shaft section 5 and is welded with built-up welding section 3 and fixes, the right-hand member machined car of built-up welding section 3 goes out the chamfering consistent with ductile iron pipe socket, finally meet built-up welding section 3 and total length that socket overlaps 2 is 0.3 meter, at this moment just can cast the ductile iron pipe of 5.7 meters of applicable Container Transports; When needing the ductile iron pipe of casting 6 meters, only need the built-up welding section 3 machined car of fixing socket cover 2 to fall, socket cover 2 can reuse.This structure, on the basis of a pipe die body, can meet the casting requirement of the ductile iron pipe of 5.7 meters, can meet again the casting requirement of the ductile iron pipe of 6 meters, and socket cover can reuse, structure is simple, and pipe die service efficiency is high, has greatly saved production cost.
It should be noted that the present embodiment is most preferred embodiment of the present invention, be not restriction the present invention being made to other form, any those skilled in the art of belonging to may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent implementations of equivalent variations.But every do not depart from the prerequisite of the technology of the present invention principle under, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present invention, all should fall into scope of patent protection of the present invention.
