Embodiment 1

[0020] Such as figure 1 As shown, a piece of Shula Haiwei blank blade is listed below.

[0021] 1) Take a photo of the cast blank blade and send the image to the computer. After comparing the three-dimensional digital-analog imaging, it is found that the upper surface of the blade corner is 30mm less than the standard digital model, and the lower surface is 30mm longer. (The deformation area is about 1.6㎡)

[0022] 2) Place the Shula Haiwei blank blade (hereinafter referred to as the blank blade) on the steel plate platform, clamp the blank blade and the steel plate platform with a clamping tool, and spot weld the two ends of the clamping tool with the blank blade and the steel plate platform respectively ;

[0023] 3) Use refractory bricks to build a hollow heating wall on the steel plate platform below the deformation area of ​​the blank blade. The heating wall is built to the lower edge of the blank blade. The periphery of the heating wall is surrounded by rock wool felt ...

Embodiment 2

[0029] Such as figure 2 As shown, a piece of rough leaves of Tugutang is listed below.

[0030] 1) Take a picture of the cast blank blade, and send the image to the computer. After comparing the three-dimensional digital-analog imaging, it is found that the upper surface of the blade corner is 50mm shorter than the standard digital analog, and the lower surface is 50mm longer. (The deformation area is about 6㎡)

[0031] 2) Put the blank blade of Tugutang (hereinafter referred to as the blank blade) on the steel plate platform, clamp the blank blade and the steel plate platform with a clamping tool, and spot weld the two ends of the clamping tool with the blank blade and the steel plate platform respectively;

[0032] 3) Use refractory bricks to build a hollow heating wall on the steel plate platform below the deformation area of ​​the blank blade. The heating wall is built to the lower edge of the blank blade. The periphery of the heating wall is surrounded by rock wool felt...

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 [0001] The invention relates to an orthopedic method, in particular to an orthopedic method for blank blades. Background technique [0002] The blades are prone to deformation during the process of boxing, heat treatment and subsequent treatment. Welding deformation or spot welding and stretching are usually used for baking. This conventional orthopedic method has a complex process and is not easy to control the amount of orthopedic, and the orthopedic cost is high, and the production cycle is also lengthened. In particular, the presence of welding heat-affected zones in the method of welding repair has a great impact on the overall casting quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a method for rectifying blank blades, which has a simple rectification process, saves production cost and reduces production cycle. [0004] To achieve th...
