Description

A kind of bending machine die of flanging
Technical field
The invention belongs to the mould applications that bender uses, more particularly, relate to a kind of bending machine die of flanging.
Background technology
Bender is a kind of machine, the especially metal-processing industry that industry is commonly used now, and the application of bender is more general, and bender is to rely on mould to complete various bending operations, so mould has determined the operation that bending function completes.Flanging operates operation conventional while being existing plate processing, for different bending demands, traditional shifting gears is that shape by changing bending machine die bed die is processed different shapes, existing bending machine die is generally that workpiece is placed between upper/lower die in the time of bending operation, then depress mold, workpiece is pressed in groove corresponding on bed die to the two ends perk of workpiece, but for the larger workpiece of area, we usually need workpiece to carry out alice processing, sometimes need to stick up twice, but utilize existing mould to carry out flanging processing, in the time of flanging, the both sides at flanging place all can stick up, if workpiece is larger, sticking up can be more difficult, for the larger workpiece of area, the height of possible perk can exceed the height of factory building, processing is inconvenient, but also may cause the accident, when so now a lot of factories carry out flanging to large-scale workpiece, need workman to carry out by hand flanging, not only inefficiency, and outward appearance is not attractive in appearance, unstable product quality.
Chinese Patent Application No.: 201110047827.4, open day 2011-09-14, applicant: Suzhou ace Manufacturing Co., Ltd., apply for that a name is called a kind of patent application document of Bending Mould, this disclosure of the invention a kind of Bending Mould, comprise bending lower die and with the supporting bending upper die of described bending lower die, in described bending lower die, have V-arrangement bending groove, in the V-arrangement bending groove of described bending lower die, have reinforcement post.The die cost of this invention is low, easy to operate, surface quality of workpieces is good, can change flexibly the shaped position of reinforcement, in the time completing bending, generated reinforcement, reinforcement contributes to submit to the Rigidity and strength of product simultaneously, thereby has reduced product stress and the distortion that produces, ensure the intensity of product, improved the quality of product.
China Patent No. 01819384.6, open day 2004-02-18, patentee Honda Motor Co., has applied for that a name is called the patent of bending method and equipment thereof, and this invention is mainly that the first flanging die unit and the second flanging mould cellular installation are in single press.The first flanging die unit carries out part bending to one side of workpiece.To give the second flanging die unit through the bending work piece delivery of part.The second flanging die unit carries out remaining necessary bending to one side of workpiece.Here, only moving downward of the patrix by the first and second flanging die units just can complete the predefined curved of edge to workpiece, and not need to use cam or cam driver in single press.
All there is complex structure in above-mentioned flanging mould and the patent of bending method and equipment thereof, the problem of flanging weak effect, the larger workpiece of area is carried out to flanging add man-hour if topmost problem is these two parts of patents, the both sides at flanging place all can stick up, processing is inconvenient, the generation that may cause the accident, is not suitable for the larger workpiece of area to carry out flanging work; And to need the workpiece major part of alice processing be all iron and steel, there is certain elastic recovery capability, when bending, the angle on workpiece both sides is 90 °, after bending, is greater than 90 ° because strain becomes again, reprocessing is to 90 ° of special difficulties just.
Summary of the invention
the problem solving
Be not suitable for the larger workpiece of area to carry out flanging processing for existing flanging mould, and manual flanging processing exists quality unstable, profile is not attractive in appearance, and the problem wasting time and energy the invention provides a kind of bending machine die of flanging.
technical scheme
For addressing the above problem, the invention provides following technical scheme:
A bending machine die for flanging, comprises mold and bed die, and described bed die comprises dwang, base, support, connecting rod, spring and supporting plate; Fluted in the middle of described base, the both sides of groove are projection, in the projection on the groove left side, have spring, and the lower end of spring is connected with the projection on the groove left side, and the other end is connected with the bottom surface of supporting plate left end; Described support is fixed on base; Described supporting plate is tabular, and the bottom surface of supporting plate right-hand member is connected with one end of connecting rod; The other end of described connecting rod is connected with dwang; Described dwang is a numeral " 7 " type, in the middle of dwang, fixes on the support of base by hinges fixing, and dwang can rotate by the hinge on this support; The bottom surface of described mold is plane.
Described mold right flank has a groove, and groove is square.Groove can be also other shapes, and groove is mainly during for flanging, can make the limit that workpiece is turned up can enter groove, and through repetition test, the effect of square groove in the time of flanging is best.
Being connected through the hinge the other end and being connected all of dwang of being connected of described supporting plate and connecting rod, connecting rod.When mold presses down, supporting plate also moves downward, and supporting plate promotes to rotate centered by the hinge of dwang in the middle of dwang by connecting rod, and the upper end of dwang will apply a power to plate workpiece, makes workpiece complete bending.
The upper level of described supporting plate will be greater than or equal to the height of dwang in the time that spring is upspring.Mainly convenient when placing tabular workpiece.
beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) bed die of the present invention is by dwang, base, support, connecting rod, spring and supporting plate, fluted in the middle of base, the both sides of groove are projection, in the projection on the groove left side, there is spring, the lower end of spring is connected with the projection on the groove left side, the other end is connected with the bottom surface of supporting plate left end, support is fixed on base, supporting plate is tabular, the bottom surface of supporting plate right-hand member is connected with one end of connecting rod, the other end of connecting rod is connected with dwang, dwang is a numeral " 7 " type, in the middle of dwang, fix on the support of base by hinges fixing, dwang can rotate by the hinge on this support, the right flank of mold has a groove, bottom surface is plane, when use, only workpiece need be placed on supporting plate and dwang, depress mold, workpiece moves down, and part on dwang is by perk, and part on supporting plate continues to move down some distances, do not need perk, easy to process, handling safety,
(2) mold right flank of the present invention is fluted, and when alice operation, dwang can put in groove, while making alice, the angle on workpiece both sides is less than 90 °, like this in the time that the strain of workpiece is recovered, can reach 90 ° or approach 90 °, after only need process a little, manufacturing procedure is simple;
