Put.
The content of the invention
The present invention provides a kind of single-point integral mould, its object is to provide a kind of mould for curved-surface piece processing, employs
This mould not only contributes to improve forming efficiency and forming accuracy, can also reduce processing cost.
The present invention adopts the technical scheme that, by multiple single-point type supporting mechanisms, upper backup pad, lower supporting plate, riser with
And motor composition；
The single-point type supporting mechanism moves up and down formula push rod by spiral and stationary rotary driving handle is constituted, single-point type branch
Support mechanism is constituted and is machined with mould, described upper backup pad in band with certain spacing squarely matrix and circular matrix arrangement
The hole of screw thread, lower supporting plate carries unthreaded hole.
Spiral of the present invention moves up and down formula push rod top and is divided into screwed cylinder, and the latter half is at least one
Individual face is the solid of plane.
Spiral of the present invention moves up and down the screwed cylinder in upper part and spiral shell in upper backup pad band of formula push rod
The hole of line forms spiral or descending motion pair.Formed between stationary rotary driving handle and lower supporting plate of the present invention
Revolute pair.
The motor of driving stationary rotary driving handle of the present invention is arranged on lower supporting plate.
Upper backup pad of the present invention is connected with lower supporting plate by riser.
Single-point integral mould of the present invention bear the size of pressure by upper backup pad and can spiral move up and down formula push rod and determine.
Compared with the patent that the present invention is retrieved more than：Although all it is technically that make use of multiple spot thought to constitute mould, and
Demand of the different curve part to type face is met by adjusting multiple spot, but is with the device main distinction of this patent, it is all of above
Patent be all to employ square drift, and the center portion of square drift is threaded hole, is connected by screwed hole with screw rod, leads to
Cross and rotate following screw thread and move up and down square body, and the maximum of this patent is different and feature is employed with externally threaded
Cylinder, cylinder not only can be moved up and down independently, while can be with separately machined workpiece.That is, a drift or one
Row's drift can just process workpiece.Secondly, above patent also resides in the application patent with this patent difference and employs a upper branch
Fagging, can so strengthen each cylinder strength, while cylinder is not mutually interdependent, it is existing that lodging is not present when processing workpiece
As；And the multiple spot drift of patent described above depends on each other for existence, using dense arrangement, after type face is adjusted, upper die and lower die add
Carry so that drift lodges, so that the shape for changing type face reduces the surface accuracy of workpiece to be machined, it is special that this is mainly the above
The essence defect of profit causes, and has a disadvantage in that all drifts are employed square, it must mutually nestle and move up and down, such as
Fruit allows it to move, and certain gap must be kept between it, while all drifts will be fettered just by the coaming plate of outermost
Multiple spot mould can be kept not produce larger lodging in stress.
Single-point Collapsible structure is used for integral mould by the present invention, for processing by thin plate to slab, while for difference
The curved-surface piece of shape is processed.With once manufacturing, the characteristics of different structure is used for multiple times, while for greatly enhancing part,
It can just be completed using multistep shaping.
It is an advantage of the invention that employing with externally threaded cylinder, cylinder not only can be moved up and down independently, together
When can be with separately machined workpiece.Secondly, present invention employs a upper backup pad, each cylinder strength can so be strengthened,
Cylinder is not mutually interdependent simultaneously, and lodging phenomenon is not present when processing workpiece；By the invention it is possible to which continuous high-efficient processing is various
Curved-surface piece of different shapes, while the Machining of Curved Surface in large-sized sheet material can be realized, it is to avoid tangible mold is processed is different to meet
The processing of shape curved-surface piece is cost-effective.
