Abstract
The invention relates to a blank blade correction method. A cast blank blade is photographed, pictures are transmitted to a computer, the size of the blank blade is fit through a measuring scale and a three-dimensional number model, the blank blade is compared with a standard blade numerical model, and the deformation region and the deformation amount of the blank blade are determined; the blade is fixed to a steel plate platform and heated through a stacking heating wall and a heating burner, the blade is corrected multiple times through a jack via external force, and therefore the blank blade correction purpose is achieved; finally, the blade is delivered into a heat treatment furnace for relieving stress and shaping. By the adoption of the method, the correction process is simple, production cost is saved, a production period is shortened, a welding heat influence region is reduced, and product quality is improved.
Description
Technical field
The present invention relates to straightening method, particularly a kind of straightening method of blanking blade.
Background technology
Blade all easily produces distortion in the process such as shake out, heat treatment and subsequent treatment.Usually soldering deflection or spot welding lacing wire baking is all adopted.The complicated orthopedic amount of this common orthopedic procedure is not easy to control, and orthopedic cost is higher, and the production cycle also lengthens simultaneously.There is welding heat affected zone and considerable influence produced to single-casting quality in the method for special soldering.
Summary of the invention
Technical problem to be solved by this invention overcomes the straightening method that the deficiencies in the prior art provide a kind of blanking blade, and orthopaedic procedures is simple, saves production cost, reduces the production cycle.
For achieving the above object, the present invention realizes by the following technical solutions:
A straightening method for blanking blade, concrete operation step is as follows:
1) cast blank blade is taken pictures, and image is sent to computer, and passing ratio chi and three-dimensional digital-to-analogue fit to blanking blade size, to compare the deformed region and deflection of determining blanking blade with rule blade digital-to-analogue;
2) blanking blade is placed in plate platform, with replacer, blanking blade and plate platform is clamped, the two ends of replacer respectively with blanking blade and plate platform spot welding, require that weld bond can not loosen in orthopaedic procedures;
3) hollow heating pad wall is piled up with in the plate platform of refractory brick below blanking blade deformed region, heating pad wall builds blanking blade lower edge by laying bricks or stones, heating pad wall is peripheral surrounds insulation with rock wool blanket, rock wool blanket thickness is 30-50mm, heating pad wall is piled up at body of wall internal fixtion gas heating burner in process, and burner quantity is between 4-6;
4) plate platform near deformable blade district is fixed a mark post, on mark post mark until orthopedic district original position and orthopedic after final position;
5) put burner heating, orthopedic for blade district is heated to 600-700 DEG C, adds external force orthopedic with jack, orthopedic gradation is carried out, each orthotic procedure interval 0.5-1 hour, till reaching orthopedic amount;
6) the blade replacer in orthopedic district is fixed on mold;
7) close firing equipment, enter heat-treatment furnace and carry out stress-removal sizing.
Compared with prior art, the invention has the beneficial effects as follows:
Orthopaedic procedures of the present invention is simple, saves production cost and production cycle, reduces welding heat affected zone simultaneously and improves the quality of products.
