Abstract
The utility model relates to a blade shelf for thermal treatment. The blade shelf is characterized in that a plurality of grooves are disposed on the upper surface of a rectangular cast base, and the size of each groove matches with that of each blade. Suspension lugs are further disposed on the base. Compared with the prior art, the blade shelf for thermal treatment has the advantages that a plurality of blades are uprightly placed and fed into a kiln for thermal treatment, are not easy to deform and can be fed into the kiln for thermal treatment simultaneously, thermal treatment cycle is shortened, thermal treatment cost is reduced, and as proved by practice, the shelf is excellent in thermal treatment effect when being used for mixed flow type blades of water-turbine generator sets.
Description
Technical field
The utility model relates to thermal treatment frock field, particularly a kind of blade thermal treatment laying rack.
Background technology
Be applied to the blade in the hydraulic generator unit, be divided into axial--flow blading and runner bucket, axial--flow blading has spindle nose; Can directly stand on the kiln car during last kiln thermal treatment, runner bucket is a complex spatial warped surface, can not stand on the kiln car; Can only lie low on kiln car, for guaranteeing to be heated evenly, generally selection level is put; Be about to blade lie low the object putting on the thermal treatment kiln car or put an ability support blade blade stand up lean against above, its weak point one is the blade easy deformation, the 2nd, the heat treatment kiln utilization ratio is low; Can not place multiple-blade, heat treatment kiln can not fully utilize, and production efficiency is low.
Summary of the invention
The purpose of the utility model provides a kind of blade thermal treatment laying rack, overcomes the deficiency of prior art, and under the indeformable prerequisite of blade, as far as possible blades of placing to improve the utilization ratio of heat treatment kiln more.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of blade thermal treatment laying rack is characterized in that, at rectangle crucible former upper surface groove a plurality of and the blade dimensions coupling is set.
Also be provided with hanger on the said base.
Compared with prior art; The beneficial effect of the utility model is: blade adopts the upright kiln thermal treatment of laying out; Blade is not easy distortion, and can make a plurality of blades go up kiln thermal treatment simultaneously, has shortened heat treatment cycle and thermal treatment cost; Facts have proved that hydraulic generator unit runner bucket adopts this laying rack thermal effectiveness fine.
Description of drawings
Fig. 1 is the utility model result of use synoptic diagram.
Among the figure: 1-base 2-groove 3-hanger 4-blade
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1, a kind of blade thermal treatment of the utility model laying rack result of use synoptic diagram is provided with a plurality of and grooves 2 blade 4 size match at rectangle crucible former 1 upper surface.Also be provided with hanger 3 on the base 1.During use two laying racks are arranged in parallel within on the kiln car, the water inlet limit with blade 4 just is inserted in the laying rack groove 2 on the rising head limit again, and the rest may be inferred puts other blade with parallel the standing of first blade, so just a plurality of blades of thermal treatment simultaneously.All pass through the same with other foundry goods of base 1 made die model, rising head, and sand mold, gating system, cast at last forms, and can change the width and the quantity of groove 2 according to the space situation and the blade dimensions situation of heat treatment kiln, can make things convenient for on-the-spot operation like this.
Claims (2)
1. a blade thermal treatment laying rack is characterized in that, at rectangle crucible former upper surface groove a plurality of and the blade dimensions coupling is set.
2. a kind of blade thermal treatment laying rack according to claim 1 is characterized in that, also is provided with hanger on the said base.
