Can rapidly alignment fiducials helix, improve operating efficiency.
Utility model content
The purpose of this utility model is intended at least solve one of described technological deficiency.
Therefore, the purpose of this utility model is to propose a kind of helical blade tube pressed mould, helical-blade mostly is solved at present
The problem of piece shapes inconsistent using hydraulic press stretch forming, therefore each helical blade.
To achieve these goals, the utility model provides a kind of helical blade tube pressed mould, including：Upper mold, lower tire
Tool, the upper mold is placed on above lower mold, and the upper mold includes upper mold pedestal, multiple upper leads, upper spiral tabletting,
The lower section of the upper mold pedestal is provided with upper spiral tabletting, provided with multiple between the upper spiral tabletting and the upper mold pedestal
Upper lead,
The lower mold includes lower mold pedestal, positioning core axle, multiple lower leads, lower spiral tabletting, the lower mold
The center of pedestal is provided with positioning core axle, and the top of the lower mold pedestal is provided with lower spiral tabletting, and the lower spiral tabletting passes through
The multiple lower leads set between the upper mold pedestal are fixed.
Further, when the upper mold is with the lower mold combination application, in the positioning core axle and the upper mold
Heart correspondence, the lower spiral tabletting is corresponding with the upper spiral tabletting.
Further, when the upper mold is with the lower mold combination application, the outer surface of the positioning core axle scribbles profit
Consistent lubricant.
Further, when the upper mold is with the lower mold combination application, the upper mold and the lower mold are all solid
Due on forcing press, and provided with the helical blade blank after expansion between the upper spiral tabletting and the lower spiral tabletting.
Further, the hypotenuse group for the more than one piece right-angled trapezium gusset that the lower spiral tabletting is radially divided equally using positioning core axle
Into helicoid.
Further, the hypotenuse group for the more than one piece right-angled trapezium gusset that the upper spiral tabletting is radially divided equally using positioning core axle
Into helicoid.
During utility model works, the helical blade blank after expansion is placed on the upper spiral tabletting of upper mold and lower tire
Before the lower spiral tabletting of tool, using forcing press to being suppressed between upper mold and lower mold, keep after certain time, prevent
Resilience, final compressing, the more than one piece right angle all radially divided equally using positioning core axle due to upper spiral tabletting and lower spiral tabletting
The hypotenuse composition helicoid of trapezoidal gusset, therefore the helical blade being pressed into each helical blade shaping is consistent, profile surface effect
It is really good, and profile surface size controls well, can in assembly welding rapidly alignment fiducials helix, improve operating efficiency.
In the utility model, the upper spiral tabletting of upper mold and the lower spiral tabletting of lower mold using spiral camber into
Shape, because continuous curve surface manufacture difficulty is larger, and high processing costs, the cycle is long, therefore uses the more than one piece radially divided equally along mandrel
The hypotenuse composition helicoid of right-angled trapezium gusset so that the manufacturing process of whole mold avoids machining, improves work effect
Rate, and reduce manufacturing cost.
The utility model is because blank is in forming process, and the frictional force between internal diameter and mandrel is larger, therefore in compacting
During the surface of positioning core axle need to apply moderate lubrication fat.
The additional aspect of the utility model and advantage will be set forth in part in the description, partly by from following description
In become obvious, or by it is of the present utility model practice recognize.
