Example 1:
the helical blade die-casting shaping frock that this embodiment provided includes base 1, projection 2, briquetting 4 and compression leg 5, wherein:
the base 1, the convex column 2, the pressing block 4 and the pressing column 5 are all solid structural members made of cast iron. The convex column 2 is fixedly arranged on the top surface of the base 1, specifically, the convex column 2 and the base 1 are integrally formed or the convex column 2 is welded on the base 1, and the top surface of the convex column 2 is a first spiral surface 21. The pressing column 5 is fixedly arranged on the bottom surface of the pressing block 4, specifically, the pressing column 5 and the pressing block 4 are integrally formed or the pressing column 5 is welded on the pressing block 4, and the bottom surface of the pressing column 5 is a second spiral surface 51 matched with the first spiral surface 21.
When this frock is produced helical blade 9, place the sheetmetal on the first helicoid 21 of projection 2, utilize compression leg 5 from last to pressing the sheetmetal down for the second helicoid 51 and the sheetmetal contact of compression leg 5, like this, first helicoid 21 and second helicoid 51 are located the below and the top of sheetmetal respectively, because first helicoid 21 and second helicoid 51 match each other, under the cooperation of first helicoid 21 and second helicoid 51, can form the helical blade 9 shape that corresponds with first helicoid 21 and second helicoid 51 with the sheetmetal die-casting. The pressing block 4 is arranged, so that the force of the pressing column 5 pressing on the metal sheet is larger, and the base 1 is arranged, so that the whole tool is stably placed at a certain position, such as the ground, a workbench and the like.
The center of the top surface of the convex column 2 is fixedly provided with a positioning column 3 which is coaxial with the convex column 2, the center of the top surface of the pressure column 5 is provided with a positioning hole 52 which is matched with the positioning column 3, the positioning hole 52 is coaxial with the pressure column 5, when the helical blade 9 is formed by die casting, the positioning column 3 is inserted into the positioning hole 52 in a sliding manner, so that the matching between the convex column 2 and the pressure column 5 and between the first helical surface 21 and the second helical surface 51 is positioned, and the helical blade 9 obtained by die casting is more accurate.
Through the structure, the helical blade die-casting forming tool provided by the embodiment has the advantages that by means of the convex column 2, the first helical surface 21 on the convex column 2, the pressing column 5 and the second helical surface 51 on the pressing column, an operator only needs to place a metal sheet on the first helical surface 21 of the convex column 2, and by means of the self-gravity of the pressing column 5 and the pressing block 4, the pressing column 5 can move downwards to enable the second helical surface 51 to be in contact with the metal sheet from the upper side, so that the helical blade 9 corresponding to the first helical surface 21 and the second helical surface 51 can be easily obtained, finally, the pressing block 4 and the pressing column 5 are lifted, and the formed helical blade 9 is taken down, so that the operation is simple and convenient, and the production efficiency of the helical blade 9 is improved nowadays. And each time the shaping obtains helical blade 9 shape and precision controllable, each time the shaping obtains helical blade 9 sameness also higher, after obtaining a plurality of helical blade 9 through this frock, through the welding mode with a plurality of helical blade 9 welding together form the flight can. It should be noted that, the molded spiral blade 9 is left on the first spiral surface 21 and surrounds the positioning column 3, and an operator needs to use another metal sheet to stir the molded spiral blade 9, so that the spiral blade 9 is separated from the first spiral surface 21, and then the spiral blade 9 is taken down.
Alternatively, the number of turns of the first and second helicoids 21 and 51 is n, where 0.5 ≦ n ≦ 1, and specifically, n may be 0.5, 0.6, 0.7, 0.8, 0.9, 1, and so on.
