Description
[technical field]
The utility model relates to diel field, particularly a kind of diel that can improve thick long bending part formed precision.
[background technology]
Bending is stamping procedure conventional in manufacturing industry, and the materials processing of sheet can be become to have the product of certain space morphological requirements by this operation.Bending part generally has a lot of installing hole, and only have angle and length to satisfy the demand could normal assembling simultaneously.Because the form of bending part is different, adds and also have different difficult points man-hour.For the workpiece that thickness is larger, stamping press not only may bring the bending of material, also can cause drawing material or distortion, if in the workpiece that length is larger, range error is easy to amplify because of angular error.As shown in Figure 1, this workpiece 3 comprises first surface 31, second face 32, the 3rd face 33 and fourth face 34, the long face that wherein this example of first surface 31 length and width is larger.Workpiece 3 is formed through three right-angle bendings by a sheet material, and last bending at knuckle 3a, thus makes fourth face from 34 ' position transfer to 34 positions, and first surface 31 and fourth face 34 require to be positioned at same plane.Easily there is displacement in product in the bending operation of free forming, and because first surface 31 is longer, very little displacement also can bring flatness error very high between first surface 31 and fourth face 34.
Therefore, be necessary to provide a kind of thick machining long workpieces Bending Mould newly to solve above problem.
[utility model content]
Main purpose of the present utility model is to provide a kind of diel that can improve thick long bending part formed precision.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of thick machining long workpieces Bending Mould, it comprises the moving platen and solid plate that are oppositely arranged, described solid plate is provided with bending insert, on described moving platen, corresponding bending insert site is mobilizable is provided with briquetting, be provided with spring between described briquetting and moving platen, described moving platen be positioned at described briquetting side and be provided with Bending punch; The side described solid plate being positioned at described briquetting is also provided with a pair positive stop for the long face of holding workpiece, and described positive stop is fixed perpendicular to described solid plate, and described two positive stops are parallel to each other.
Preferably, described positive stop is embedded in a pedestal, and described pedestal is fixed on described solid plate.
Preferably, described spring adopts nitrogen spring.
Preferably, the bottom surface of described bending insert is provided with beading.
With prior art mutually this, the beneficial effect of the thick machining long workpieces Bending Mould of the utility model is:
1, utilize workpiece to have the feature in long face, with the initial position of vertically disposed positive stop restriction workpiece patrix, avoid workpiece generation sidesway in punching press, and higher with the positional precision in the long face of Angle ambiguity.
2, pedestal can make positive stop fixing more surely on solid plate, prevents the perpendicularity of the effect of jitter workpiece of positive stop itself.
3, the sudden change of nitrogen spring elastic force is fast, briquetting and bending insert primary clamp force can be made to raise fast, make bending stage workpiece because of impulse force, sidesway can not occur easily, ensure positional precision further.
4, the beading in bending insert produces sclerosis at knuckle position after can making material bending, discharges the resilience caused, make bending perpendicularity more accurate to weaken material stress.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 2, shown in Fig. 3, the utility model is a kind of thick machining long workpieces Bending Mould, comprise the moving platen 11 and solid plate 21 that are oppositely arranged, solid plate 21 is provided with bending insert 22, on moving platen 21, corresponding bending insert 22 position is mobilizable is provided with briquetting 14, nitrogen spring 13 is provided with between briquetting 14 and moving platen 11, moving platen 11 is positioned at briquetting 14 side and is provided with Bending punch, side solid plate 21 being positioned at briquetting 14 is also provided with a pair positive stop 23 for the long face of holding workpiece, positive stop 23 is embedded in a pedestal 24, pedestal 24 is fixed on solid plate 21.Positive stop 23 utilizes workpiece to have the feature in long face, limits the initial position of workpiece, avoids workpiece generation sidesway in punching press, and higher with the positional precision in the long face of Angle ambiguity.Pedestal 24 can make the stability of positive stop 23 itself higher, prevents its shake and affects workpiece perpendicularity.
With reference to Fig. 4, bending insert 22 bottom surface is provided with beading 221, and beading 221 can make knuckle 3a position quick-hardening, discharges the resilience caused, make bending perpendicularity more accurate to weaken material stress.
With reference to Fig. 2, during patrix, the second face 32 holder of workpiece 3 is held in bending insert 22, and first surface 31 is held between a pair positive stop 23, such workpiece 3 cannot move left and right, and avoids workpiece 3 in punching press and sidesway occurs, and higher with first surface 31 positional precision that Angle ambiguity is elongated; When bending starts, dynamic model 11 drives Bending punch 12 and briquetting 14 descending, when workpiece 3 encountered by briquetting 14, nitrogen spring 13 starts compression, now nitrogen spring 13 produces an elastic reactance rapidly, briquetting 14 and bending insert 22 is made to be clamped by workpiece 3, nitrogen spring 13 compress while Bending punch 12 continue descending, then Bending punch 12 collide workpiece 3 make its knuckle 3a place generation bending.Because nitrogen spring 13 can produce high resiliency fast, make workpiece 3 in whole Forging Process because of the pulling force of deformation position, sidesway can not occur, relatively common spring can improve stamping position precision.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
