Technical field
The utility model relates to a kind of process equipment of automobile double step pipe part, is specifically related to a kind of double step pipe upset head mould.
Background technology
In the manufacturing process of the double step pipe part of automobile engine, generally for the oral area intensity increasing pipe fitting and the sealing be connected with external hose, usually design in pipe port portion together or the step of twice projection, as shown in Figure 5.Producer generally adopts machined and soldering.First go out by lathe process the pipe that a length of tape has double step, then by pipe together with weld parts to be processed, also need surface finish smooth after welding.There is working (machining) efficiency low, the shortcomings such as labor strength is large.In addition Ye You producer uses button head machine to carry out heading process, and automaticity is high, greatly facilitates production.But the pipe being only limited to single step is at present produced, and cannot use the pipe of double step.Therefore a kind of double step pipe upset head mould is needed to solve above-mentioned Problems existing.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of simple and reasonable a kind of double step pipe upset head mould, and use this mould can process double step pipe on upsetting is speculated, production efficiency is high.
The technical solution of the utility model is achieved in that a kind of double step pipe upset head mould comprises by the upper die and lower die be bolted together, it is characterized in that, described patrix comprises upper bolster and combination and is arranged on go forward core rod and upper rear core rod on upper bolster, described in go forward core rod and upper rear die core front end be provided with the first forming tank and upper second forming tank successively; Described counterdie comprises die shoe and combination and is arranged on lower front core rod on die shoe and lower rear core rod, and described lower front core rod and lower rear core rod are provided with lower first forming tank corresponding with described upper first forming tank and upper second forming tank, lower second forming tank successively; Described upper bolster is provided with detent, and die shoe is provided with the locating convex block matched with detent; The die cavity internal diameter that described upper first forming tank, upper second forming tank, lower first forming tank and lower second forming tank surround and circular hole external diameter to be processed match.
Preferably, described upper first forming tank and lower first forming tank sidewall outer are provided with chamfering.
Preferably, the distance between described upper first forming tank and upper second forming tank is identical with the step spacing of double step pipe.
Described upper bolster top offers installation fixing hole.
Preferably, described double step pipe upset head mould is made up of CrWMn, 9Mn2V, 7CrSiMnMoV or 6CrNiSiMnMoV material.
The utility model solves the defect existed in background technology, has following beneficial effect:
A kind of double step pipe upset head mould that the utility model provides is rational in infrastructure, the utility model carries out punching press by button head machine to the pipe in double step pipe upset head mould, the effect of one time punching molded double step can be realized, not only crudy is good, and efficiency is high, eliminate and weld and the operation such as polishing in the past, save the production cycle.The upper and lower mould of this upset head mould combines installation by die holder, front core rod and rear core rod and forms, therefore only need by changing die holder up and down and the upper and lower front and back core rod of different model size, just can realize the rapid processing of sizes pipe step, save production cost, further increase production efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of double step pipe upset head mould as shown in Figure 1, Figure 2 and Figure 3, comprise by the patrix 1 be bolted together and counterdie 2, patrix 1 comprises upper bolster 11 and combines go forward core rod 12 and the upper rear core rod 13 that are arranged on upper bolster 11, described in go forward core rod 12 and upper rear core rod 13 front end be provided with the first forming tank 121 and upper second forming tank 131 successively; Counterdie 2 comprises die shoe 21 and combines the lower front core rod 22 and lower rear core rod 23 that are arranged on die shoe 21, and lower front core rod 22 and lower rear core rod 23 front end are provided with lower first forming tank 221 corresponding with upper first forming tank 121 and upper second forming tank 131, lower second forming tank 231 successively; Upper bolster 11 is provided with detent 111, and die shoe 21 is provided with the locating convex block 211 matched with detent 111; The die cavity internal diameter that described first forming tank 121, upper second forming tank 131, lower first forming tank 221 and lower second forming tank 231 surround and circular hole to be processed 5 external diameter match.Upper first forming tank 121 and lower first forming tank 221 sidewall outer are provided with chamfering.Distance between upper first forming tank 121 and upper second forming tank 131 is identical with the step spacing of double step pipe.Upper bolster 11 top offers installation fixing hole.Double step pipe upset head mould is made up of CrWMn, 9Mn2V, 7CrSiMnMoV or 6CrNiSiMnMoV material, has good intensity and anti-wear performance.
Process of the present utility model is: 4 illustrate by reference to the accompanying drawings.Good for this upset head mould mounting and adjusting on button head machine, upper bolster 11 is fixed on lifting hydraulic cylinder 3 by screw and connecting plate.Then pipe 5 to be processed is put into counterdie 2, pipe external diameter and lower front core rod 22 and lower rear core rod 23 are posted.Then start lifting hydraulic cylinder 3, make patrix 1 close towards counterdie 2, compress pipe 5 to be processed.Start button head machine, its heading pressing mold 4 moves forward, and pipe 5 to be processed is extruded jumping-up by the plug in heading pressing mold 4.The size of plug, upper and lower first forming tank and upper and lower second forming tank and positional structure determine the shape of the step that final metal tube head is pressed into.Heading pressing mold 4 pushes back by last spring, loosens patrix, takes out forming part, namely completes a heading.Adopt the utility model just can suppress the step of two projections at pipe 5 nozzle position place to be processed by heading.In addition the upper and lower mould of this upset head mould is formed by die holder, front core rod and rear core rod combination installation, therefore only need by changing die holder up and down and the upper and lower front and back core rod of different model size, just can realize the rapid processing of sizes pipe step, further increase production efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
