Abstract
The utility model relates to the fold of cold forging of a gear, and discloses an integral extrusion device of an impeller shaft. The integral extrusion device of the impeller shaft comprises an upper die sleeve 4, a lower die sleeve 5, a lower die fixing seat 6, an upper spline die 2 and a lower spline die 7. An upper die cushion 1 is arranged above the upper spline die 2, and a lower die cushion 8 is arranged below the lower spline die 7. The integral extrusion device also comprises an upper ejector rod 3 and a lower ejector rod 9. The integral extrusion device has the characteristics that a die can be replaced rapidly, and precision in positioning is high; the involute splines on two ends can be simultaneously molded; the integral extrusion device has the advantages of stability in product quality, high production efficiency and high material utilization rate, and the weaknesses of the prior art that the material utilization rate in machining is low, the productivity is low, the product quality is unstable, and the production cost is high can be overcome.
Description
Technical field
The utility model relates to the cold forging field of gear, the monolithic extruded device of especially a kind of impeller shafts.
Background technology
Traditional processing adopts machining, on the equipment such as gear shapping machine, gear-hobbing machine, carry out, stock utilization and productivity ratio are lower, and workman's labour intensity is large, product quality and unstable, production cost is higher, and for the shortcoming of prior art, the utility model adopts building block system mould structure, can realize two ends involute spline is shaped simultaneously simultaneously, the coaxiality error of avoiding secondary clamping to cause, constant product quality, production efficiency is high.
Summary of the invention
The utility model, for shortcoming in prior art, has designed a kind of monolithic extruded device of impeller shafts of building block system mould structure.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The monolithic extruded device of impeller shafts, comprises Upper Die-sleeve, lower die-sleeve, lower model fixing seat, also comprises upper spline mould and lower spline mould.
As preferably, the monolithic extruded device of impeller shafts is provided with Upper Die-sleeve and lower die-sleeve, when production, blank is put in lower die-sleeve, along with equipment top shoe declines, blank completes closed orientation step in Upper Die-sleeve and lower die-sleeve, along with top shoe continues to decline, the top of blank enters into lower spline mould and upper spline mould, complete the extrusion molding of two ends spline simultaneously, the coaxial error of avoiding secondary clamping to cause, make product gear wheel surface highly polished, the steady quality of product is also protected, and service life is longer.
As preferably, the top of upper spline mould is provided with die-cushion, and lower spline mould below is provided with lower die-cushion.Upper die-cushion is protected upper spline mould, plays the effect of buffering, extends the service life of mould, and lower die-cushion is protected lower spline mould, plays the effect of buffering, extends the service life of mould.
As preferably, also comprise upper rod-knocking and lower push rod.
The utility model adopts building block system mould structure, has die change rapid, and the feature that positioning precision is high can realize two ends involute spline simultaneously and be shaped, and has constant product quality, and production efficiency is high, the advantage that stock utilization is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The toponym that in accompanying drawing, each number designation refers to is as follows: 1-upper die-cushion, 2-upper spline mould, 3-upper rod-knocking, 4-Upper Die-sleeve, 5-lower die-sleeve, 6-lower model fixing seat, 7-lower spline mould, 8-lower die-cushion, 9-lower push rod.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
The monolithic extruded device of impeller shafts, as shown in Figure 1, comprises Upper Die-sleeve 4, lower die-sleeve 5 and lower model fixing seat 6, also comprises upper spline mould 2 and lower spline mould 7.The top of upper spline mould 2 is provided with die-cushion 1, and lower spline mould 7 belows are provided with lower die-cushion 8, and the monolithic extruded device of impeller shafts also comprises upper rod-knocking 3 and lower push rod 9.
The course of work: first blank is put into lower die-sleeve 5 when production, along with equipment top shoe declines, blank completes the step of closed orientation in Upper Die-sleeve 4 and lower die-sleeve 5, top shoe continues to decline, the top of blank enters into lower spline mould 7 and upper spline mould 2, completes the extrusion molding of two ends spline simultaneously.When the demoulding, top shoe rises, after upper rod-knocking 3 contacts with by push rod equipment by-blow bar, because top shoe rises, product is separated with upper spline mould 2, after top shoe rises to certain position, 9 risings of equipment lower push rod make product deviate from lower spline mould 7, there is die change rapid, the feature that positioning precision is high.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
