Summary of the invention
This utility model provides a kind of single-point integral mould, its object is to provide a kind of mould for curved-surface piece processing, have employed this mould and not only contribute to improve forming efficiency and forming accuracy, it is also possible to reduce processing cost.
This utility model adopts the technical scheme that, by multiple single-point type supporting mechanisms, upper backup pad, lower supporting plate, riser and driving motor composition；
Described single-point type supporting mechanism is moved up and down formula push rod by spiral and stationary rotary driving handle forms, single-point type supporting mechanism is constituted mould with certain spacing squarely matrix and circular matrix arrangement, being machined with tapped hole on described upper backup pad, lower supporting plate is with unthreaded hole.
Spiral described in the utility model moves up and down formula push rod top and is divided into screwed cylinder, the latter half be at least one face be the solid of plane.
Spiral described in the utility model moves up and down the screwed cylinder of upper part of formula push rod and forms spiral or descending motion pair with the tapped hole of upper backup pad.Revolute pair is formed between stationary rotary driving handle described in the utility model and lower supporting plate.
The driving motor of driving stationary rotary driving handle described in the utility model is arranged on lower supporting plate.
Upper backup pad described in the utility model is connected by riser with lower supporting plate.
This utility model single-point integral mould bears the size of pressure by upper backup pad and can move up and down the decision of formula push rod by spiral.
This utility model is compared with the patent retrieved above: although being all technically to make use of multiple spot thought to constitute mould, and meet the different curve part demand to profile by adjusting multiple spot, but with the device main distinction of this patent it is, above all of patent is all to have employed square drift, and the heart portion of square drift is threaded hole, it is connected with screw rod by screwed hole, make to put body by the following screw thread of rotation to move up and down, and the maximum different and feature of this patent is to have employed with externally threaded cylinder, cylinder is possible not only to independently move up and down, simultaneously can be with separately machined workpiece.It is to say, a drift or row's drift just can process workpiece.Secondly, above patent also reside in the application patent different from this patent have employed a upper backup pad, so can strengthen each cylinder strength, and cylinder is the most interdependent simultaneously, there is not lodging phenomenon when processing workpiece；And the multiple spot drift of the above patent depends on each other for existence, use dense arrangement, after adjusting profile, upper die and lower die load, drift is lodged, thus the surface accuracy that the shape changing profile makes workpiece to be machined reduces, this essence defect being mainly above patent causes, have a disadvantage in that all of drift have employed square, it must mutually be nestled and move up and down, if allowing it move, certain gap must be kept between it, the most all of drift will rely on the coaming plate constraint of outermost that multiple spot mould could be kept will not to produce bigger lodging in stress.
Single-point Collapsible structure is used for integral mould by this utility model, for processing by thin plate to slab, is simultaneous for difform curved-surface piece and is processed.Have and once manufacture, the nonexpondable feature of different structure, for being simultaneous for greatly enhancing part, use multistep to shape and just can complete.
The utility model has the advantages that novel structure, have employed with externally threaded cylinder, cylinder is possible not only to independently move up and down, simultaneously can be with separately machined workpiece.Secondly, this utility model have employed a upper backup pad, so can strengthen each cylinder strength, and cylinder is the most interdependent simultaneously, there is not lodging phenomenon when processing workpiece；By this utility model, various difform curved-surface piece can be processed with continuous high-efficient, can be implemented in the Machining of Curved Surface of large-sized sheet material simultaneously, it is to avoid tangible mold is processed, cost-effective for meeting the processing of difformity curved-surface piece.
