Abstract
The utility model discloses a die-casting rough gear pump shaft sleeve. Sunken technical concave platforms are arranged at two sides in the middles of the front side and the back side of the rough gear pump shaft sleeve by die casting; and a sealing groove is formed in the front side of the rough gear pump shaft sleeve by die casting. The rough gear pump shaft sleeve is formed through die-casting, is accurate in size, less in allowance for machining, sand holes inside the rough gear pump shaft sleeve are few, and the surfaces are smooth, the technical concave platforms arranged can meet the clamping requirement of a clamp in the machining center, the machining center can replace tens of traditional machining equipment for high-precision machining, thereby improving the quality of shaft sleeve products and further greatly improving the quality of a gear pump; and the sealing groove formed through die-casting is not required for secondary machining, so that the working procedures are reduced, the machining time is shortened, the consumption of labor force is saved, and the processing cost is lowered.
Description
Technical field
The utility model relates to gear pump production and processing field, is specifically related to a kind of gear pump sleeve blank of die cast.
Technical background
Gear pump sleeve is the important spare part of Assembling gear pump, and how very big on the overall performance impact of gear pump its quality is.At present, the gear pump sleeve blank is many to be made by hand teeming, then saw is except cutting-off gate, through rough turn two sides, heavy boring endoporus, right boring endoporus, rough mill cylindrical, scraping cylindrical, mill two sides, mill several operation such as seal groove, make the axle sleeve finished product, need tens equipment of design, and be all to use traditional processing machine manually to operate, the product machining accuracy is poor.The gear pump sleeve blank of casting forming can't use modern high-precision machining center to carry out highi degree of accuracy processing because of structure problem.
Summary of the invention
The utility model provides a kind of gear pump sleeve blank of die cast, satisfies the fixture clamping requirement of machining center, can use machining center to carry out highi degree of accuracy processing, the axle sleeve superior product quality, and then improve the gear pump quality, and the reduction manufacturing procedure, the processing clout is little, greatly cuts down finished cost.
The utility model is achieved through the following technical solutions:
The gear pump sleeve blank of die cast, there is sagging technique concave station the both sides, positive and negative centre of described gear pump sleeve blank die casting respectively.
The further improvement of the utility model scheme is that the positive die casting of described gear pump sleeve blank has seal groove.
The utility model compared with prior art has following obvious advantage:
One, in the middle of the positive and negative of gear pump sleeve blank described in the utility model both sides respectively die casting sagging technique concave station is arranged, satisfied the fixture clamping requirement of machining center, available machining center substitutes tens traditional machining apparatus and carries out highi degree of accuracy processing, the axle sleeve product quality improves, and then greatly improve the quality of gear pump, and reduce workman's labor intensity.
Two, the utility model die cast, the front of gear pump sleeve blank integrated die-casting in press casting procedure goes out seal groove, need not again to process, and has reduced operation, shortens process time, has saved labour force's consumption, has reduced processing cost.
Three, the utility model die cast, size is accurate, and machining allowance is little, has both improved using rate of metal, the economical with materials cost, reduced again processing intensity, shortened man-hour, inner sand hole of while is few, any surface finish, through destructive testing, improve 2% with the gear pump volumetric efficiency of die casting axle sleeve than the gear pump volumetric efficiency of casting axle sleeve, total efficiency reaches more than 83%, has greatly improved the total quality of product.
The annex explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is reverse view of the present utility model.
Fig. 3 is right elevation of the present utility model.
Specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, there is sagging technique concave station 2 both sides, the positive and negative of gear pump sleeve blank 1 described in the utility model centre die casting respectively.
The positive die casting of described gear pump sleeve blank 1 has seal groove 3.
In course of working, by two-sided technique concave station 2, the clamping work in-process carries out respectively two-sided processing in the heart, and machining accuracy is high, superior product quality.
Claims (2)
1. the gear pump sleeve blank of die cast is characterized in that: in the middle of the positive and negative of described gear pump sleeve blank (1) both sides respectively die casting sagging technique concave station (2) is arranged.
2. the gear pump sleeve blank of die cast according to claim 1, it is characterized in that: the positive die casting of described gear pump sleeve blank (1) has seal groove (3).
