[0025] combine figure 1 , a method for manufacturing a water turbine blade mold, comprising the following steps:
[0026] a. Process design: use the three-dimensional mold design software to design the three-dimensional drawing of the turbine blade mold;
[0027] b. According to the blade size designed by the three-dimensional mold software, the irregular curved surface is intercepted at every 400-500mm interval to form the shape of each section;
[0028] c. Make the skeleton model: according to the intercepted surface, the machining center processes the skeleton shape of each interface, so as to determine the shape of the product on each mesh surface, and slot and position at the intersection of each interface, see image 3 ;
[0029] d. Lap joint skeleton model: After the completion of each cross-section model, it is assembled to form the outline size of the product, and the connection part of the multi-layer board is reinforced with lath, and the blade surface is spli...

A manufacturing method of a water turbine blade mould is characterized by comprising the following steps of technological design, wherein three-dimensional mould design software is utilized for designing a water turbine blade mould three-dimensional pattern, through computer programming, a standard mould machining program is formed, and according to the designed blade size, irregular curved surfaces are cut out at intervals of 400 mm to 500 mm, and manufacturing shapes of various sections are formed; framework sample plate manufacturing, wherein according to the cut-out curves surfaces, a framework shape of each interface is machined, shapes of products in all grid surfaces are determined, and crossing portions of all interfaces are slotted and positioned; framework lap joint, wherein a product contour size is formed in an assembled manner, strips are adopted to carry out reinforcing, and multilayer boards are adopted in blade surfaces for splicing; machining, wherein, after a workblank is manufactured, the workblank is machined through a machining center; and assembling, a 80*80 mm square tube is adopted in a framework for connecting, reinforcing and assembling. The manufacturing method has the beneficial effects that the manufacturing period of the water turbine blade mould is shortened, and the manufacturing cost of the water turbine blade mould is reduced.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for manufacturing a water turbine blade mold. Background technique [0002] The traditional water turbine blade mold manufacturing process mainly uses wooden beams to make the skeleton, and the blade surface is sealed with 40mm thick cedar sheet to make the blank. In this manufacturing method, a large amount of material is used, the mold manufacturing cost is high, and the mold manufacturing cycle is long. Contents of the invention [0003] Aiming at the deficiency of the prior art, the invention proposes a method for manufacturing a water turbine blade mould. The invention shortens the manufacturing cycle of the water turbine blade mould, and reduces the manufacturing cost of the water turbine blade mould. [0004] A method of manufacturing a water turbine blade mold: [0005] Include the following steps: [0006] a. Process design: use the three-dimensional m...
