Summary of the invention
The invention provides a kind of single-point integral mould, its object is to, for curved-surface piece processing provides a kind of mould, have employed this mould and be not only conducive to improving forming efficiency and forming accuracy, can also cut down finished cost.
The technical scheme that the present invention takes is, by multiple single-point type supporting mechanism, and upper backup pad, lower supporting plate, riser and drive motors composition;
Described single-point type supporting mechanism moves up and down formula push rod by spiral and stationary rotary driving handle forms, single-point type supporting mechanism is formed mould with certain spacing squarely matrix and the arrangement of circular matrix, described upper backup pad is processed with tapped hole, and lower supporting plate is with unthreaded hole.
Spiral of the present invention moves up and down formula push rod top and is divided into screwed cylinder, the solid of the latter half to be at least one face be plane.
Spiral of the present invention moves up and down the screwed cylinder of upper part of formula push rod and the tapped hole of upper backup pad forms spiral or descending motion is secondary.Revolute pair is formed between stationary rotary driving handle of the present invention and lower supporting plate.
The drive motors 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 by riser with lower supporting plate.
The size that single-point integral mould of the present invention bears pressure is by upper backup pad and can move up and down formula push rod and determine by spiral.
The present invention is compared with above retrieved patent: although be technically all make use of multiple spot thought to form mould, and meet the demand of different curve part to profile by adjustment multiple spot, but with the device main distinction of this patent be, patents all is above all have employed square drift, and the heart portion of square drift is threaded hole, be connected with screw rod by screwed hole, make to put body by the screw thread rotated below to move up and down, and the maximum difference of this patent and feature have employed with externally threaded cylinder, cylinder not only can independently move up and down, simultaneously can independent processing work.That is, a drift or once row drift can processing work.Secondly, above patent is different from this patent is also that the application's patent have employed a upper backup pad, can strengthen each cylinder strength like this, and cylinder is not interdependent mutually simultaneously, there is not lodging phenomenon when processing work, and the multiple spot drift of the above patent depends on each other for existence, adopt dense arrangement, after adjusting profile, upper die and lower die load, drift is lodged, thus the shape changing profile makes the surface accuracy of workpiece to be machined reduce, the essence defect of this mainly above patent causes, it is square that its defect is that all drifts have employed, it mutually must to be nestled and to move up and down, if allow it move, certain gap must be kept between it, simultaneously all drifts all will rely on the constraint of the coaming plate of outermost that multiple spot mould could be kept can not to 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, processes for difform curved-surface piece simultaneously.Have and once manufacture, the nonexpondable feature of different structure, simultaneously for greatly enhancing part, adopting multistep to be shaped and just can complete.
Advantage of the present invention have employed with externally threaded cylinder, and cylinder not only can independently move up and down, simultaneously can independent processing work.Secondly, present invention employs a upper backup pad, can strengthen each cylinder strength like this, cylinder is not interdependent mutually simultaneously, there is not lodging phenomenon when processing work; By the present invention, various difform curved-surface piece can be processed by continuous high-efficient, can be implemented in the Machining of Curved Surface of large-sized sheet material simultaneously, avoid tangible mold to process, cost-saving for meeting the processing of difformity curved-surface piece.
