Description

Integrated three-dimensional panel beating blade

The utility model relates to a kind of integrated three-dimensional (promptly being called for short 3D) panel beating blade, refers to the 3D panel beating blade structure of receded disk impellers such as a kind of suitable what pump, blower fan or stator especially.

At present the impeller (Impeller) on widespread what pump or the blower fan and stator (Diffuser) generally can generally be divided into two kinds of casting and panel beating systems.The pump impeller that tradition is made with die casting has shortcomings such as comparatively heavy, that material behavior is relatively poor, production process easily pollutes by what, is therefore replaced by the pump impeller of panel beating system and stator gradually now.

3D panel beating blade uses what high efficiency centrifugal pump mostly, because of its good 3D spoon of blade that has can meet good angle and the load distribution of fluid at impeller or gate vane channel, therefore can significantly improve the pumping usefulness of fluid.

Yet, known panel beating manufacturing technology can't reach the blade that one-body molded mode manufacturing has good 3D curved surface, and after only making blade one by one earlier, again these blades blocks ofly located respectively, welded between preceding, the back of the body lid of what impeller and become a complete impeller, causing now, the manufacture cost of panel beating system impeller and stator remains high.This is that the shape of its curved surface can cause the technical blind spot of stamped, and one-body molded stamping process may be implemented hardly because have the blade of good 3D curved surface flow passage structure.So the general existing one-body molded blade made from impact style (promptly, a plurality of blades can be one-body molded) all be only to have simple 2D curved blade but not perfect 3D curved surface, the angle and the load request of fluid can't be satisfied by its simple blade angle of what, what can only be suitable for so can significantly reduce pumping usefulness at a low price on the centrifugal pump product of low usefulness.

And known technology is welded the operating type of location more one by one with the blade that the monolithic stamped has good 3D curved surface, comprise but have: blade quantity is many, jig Design is complicated, the shortcomings such as accurate location difficulty of 3D blade, so that the integral body manufacturing and the assembly cost of the known 3D panel beating of what impeller are all higher relatively.

In addition, to the design of the pump of the some special purposes of what, in the time of for example need emphasizing that anti-turbulent flow (De-swirl) pump function of gate vane channel or desire improve pumping pressure, known technology has the impeller or the guide vane structure of employing multiple row (Multi--Row) blade.For example, number No. 342425 patent case of Taiwan patent announcement and U.S. Patent number US.No.5,310,309,4,877,370,5,417,547,5,516, patents such as 263,4,354,802 all are cases of inquiring into the utilization of " multiple row formula " blade structure and can reaching effect.Yet these known " multiple row formula " blade structures have only with the forging type moulding and just can produce the runner of 3D curved surface to satisfy fluid angle and loading demand.If be the words made from metal plate punching, the blade of 3D curved surface is made, locatees and assembled to pin respectively because of it needs blocks of ground again, and " multiple row formula " blade structure will significantly increase more than the integral blade quantity several times, make the degree of difficulty and the manufacture cost of impeller assembling more significantly improve, therefore still be further improved.

The purpose of this utility model, be to provide a kind of integrated 3D panel beating blade, they can be with a plurality of blades that originally need produce respectively, locate and assemble, integration becomes a few panel beating system of can once-through making and integrates lamellar body, only need integrate the lamellar body combination with this a few, promptly finish manufacturing, location and the assembly working of a plurality of blades simultaneously, not only each blade can have good 3D curved surface with raising pumping usefulness, and more can significantly reduce the degree of difficulty and the integral production cost of the assembling of blade location.

Another purpose of the present utility model, provide a kind of integrated 3D panel beating blade at what, integrate lamellar body by a plurality of blades being integrated a few panel beating system of can once-through making of whats, as long as integrate the lamellar body combination with this a few, can form one " multiple row formula " blade structure rapidly, make it can be with the high pumping usefulness of the good 3D curved surface bucket of metal plate punching system and the low-cost advantage of simplifying blade location assembling process.
