Abstract
The utility model relates to a metal blade twist shaping frock, including two the same zigzag steel sheets, its characterized in that: every zigzag steel sheet middle part is equipped with metal blade patchhole, and the both sides face at zigzag steel sheet both ends all is fixed with a dog. The end design at zigzag steel sheet both ends for semi -circular, the end of the shape of every dog and size and zigzag steel sheet is unanimously. The utility model discloses region, direction of rotation, 0 degree < torsion angle < various metal twist blade of 90 degrees are twistd reverse to applicable difference. Torsional metal blade cost is reduced.
Description
Technical field
The utility model relates to a kind of metal blade twisting tooling, is applicable to paddle, fan leaf, wind wheel leaf reverse machine-shaping, 0 degree of < torsion angle < 90 degree.
Background technology
The metal blade that usual needs reverse adopts casting, forging, shaping grinding apparatus die mould, and its manufacturing cost is very high, and a kind of mould can only the stirring vane of corresponding a kind of accessory size.
Summary of the invention
The purpose of this utility model in order to overcome above-mentioned prior art Problems existing, and provides a kind of metal blade twisting tooling.
The technical solution of the utility model is:
A kind of novel metal blade twist forming frock, comprises the identical zigzag steel plate of two pieces, it is characterized in that: be provided with metal blade patchhole in the middle part of every part zigzag steel plate, the two sides at the two ends of zigzag steel plate are all fixed with a block.Zigzag steel plate central aperture is used for metal blade and inserts, bottom block height limitation metal blade torsion angle.
The termination at described zigzag steel plate two ends is designed to circular arc end face, and termination is rotated around frock supporting surface under stressing conditions, and the shape of each block is consistent with the termination of zigzag steel plate with size.
Described zigzag steel plate materials intensity is greater than or equal to metal blade intensity.
Do not interfere as principle when the metal blade patchhole size designed in the middle part of zigzag steel plate is to insert metal blade.
During work, zigzag steel plate symmetry identical for two pieces is placed on two ends, metal blade torsion region, utilizes vertical to make two pieces zigzag steel plate produce phase detorsion, complete the torsion of metal blade.
The utility model is suitable for the various metal twist blades of different torsion region, direction of rotation, 0 degree of < torsion angle < 90 degree.Reduce the cost of the metal blade of torsion.

Detailed description of the invention
In conjunction with the accompanying drawings and embodiments, the utility model will be further described.In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; introduce to the accompanying drawing used required in embodiment or description of the prior art briefly below; accompanying drawing in apparent description is only section Example of the present utility model; for those of ordinary skill in the art; under the prerequisite not paying creative work; other embodiment can also be obtained according to these embodiments, all belong to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, the utility model comprises the identical zigzag steel plate 1 of two pieces, it is characterized in that: be provided with metal blade patchhole in the middle part of every part zigzag steel plate 1, the two sides at the two ends of zigzag steel plate 1 are all fixed with a block 2.Zigzag steel plate central aperture is used for metal blade 3 and inserts, block 2 height limitation metal blade 3 torsion angle of bottom.The termination at described zigzag steel plate two ends is designed to circular arc, and termination is rotated around frock supporting surface under stressing conditions, and the shape of each block is consistent with the termination of zigzag steel plate with size.Do not interfere as principle when the metal blade patchhole size designed in the middle part of zigzag steel plate is to insert metal blade.
As shown in Figure 3, during work, zigzag steel plate 1 symmetry identical for two pieces is placed on two ends, metal blade 3 torsion region, and all abandons putting on hydraulic press base 4, utilize the vertical of hydraulic press to make two pieces zigzag steel plate produce phase detorsion, complete the torsion of metal blade 3.The reverse part of metal blade 3 as shown in Figure 4.
The utility model is suitable for the various metal twist blades of different torsion region, direction of rotation, 0 degree of < torsion angle < 90 degree.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, all should be included within protection domain of the present utility model.
