Abstract

The utility model discloses a three-point bending die with an adjustable bending angle, belonging to the field of bending dies. The three-point bending die comprises a bending upper die and a bending lower die, wherein the bending lower die comprises a lower die main body and an ejector rod; the ejector rod is connected with a hydraulic device of a machine tool; the three-point bending die also comprises a fixing block; the fixing block is fixed on the machine tool body; and the upper part of the fixing block is fixed on the outer surface of the lower die main body through a fastening bolt. Through the die disclosed by the utility model, in a bending process, the scratches on the surface of the sheet metal are reduced through the three-point contact between the sheet metal and the lower die main body, thus the surface quality of the sheet metal is improved; and after the bending process, since the ejector rod experiences the upward hydraulic force, the sheet metal pops out of a groove under the effect of the ejector rod to realize convenient and quick unloading.

Description

A kind of bikini Bending Mould of bending adjustable angle
Technical field
The utility model belongs to the Bending Mould field, more particularly, relates to a kind of bikini Bending Mould of bending adjustable angle.
Background technology
Bending Mould is a kind of die apparatus that is used to process bending workpieces such as V-arrangement, U-shaped, plays important effect in mould applications.The groove angle of tradition bending counterdie is fixed, and every secondary bending counterdie can only bending goes out a kind of plate of angle, function singleness.When needing bending to go out the plate of differently curved angle in the actual production, must change the bending counterdie of different model, the replacing repeatedly of mould causes production efficiency low.In addition, in the prior art, the less plate of angle of bend exists plate to be stuck in easily in the counterdie groove after accomplishing the bending process, is difficult for the problem of taking out.
One Chinese patent application number: 200820131108.4; The patent document of the applying date: 2008-07-21 discloses a kind of Bending Mould; It comprises a patrix and a counterdie, and this counterdie comprises a die base, and the both sides, top of this die base are respectively equipped with a die regulating block; Form a die between these two die regulating blocks, the A/F of this die is to regulate setting through this die regulating block.Because the A/F of this die is the scalable setting, so the workpiece of the more bending radius of this bending function compacting, improved the versatility of this die; And through regulating this die ground A/F easily, and with repeatedly guarantee the die mould precision of workpiece than positive curve, even if, also can guarantee its die mould precision for the bending of orthodrome workpiece more rambunctious.The weak point of this utility model is; The angular range of the sheet material that this mould can be processed is limited, in actual production process, when running into the required bending angle of sheet material amplitude of variation when big; Still need more mold exchange; Wasted human and material resources, influenced production efficiency, but and the structural design that the die regulating block is set above the die base make machining angle can not be continuously, accurately adjust.
Summary of the invention
The technical problem that solves
To Bending Mould in the prior art cannot bending multi-angle plate and plate after bending, be difficult for the deficiency of taking out, the utility model provides a kind of bikini Bending Mould of bending adjustable angle.The mould of the utility model has more versatility than prior art, and uses the mould of the utility model, and plate discharging after bending is convenient.
Technical scheme
The purpose of the utility model realizes through following technical scheme:
The bikini Bending Mould of a kind of bending adjustable angle of the utility model comprises bending patrix and bending counterdie; Described bending counterdie comprises counterdie main body and push rod, and push rod links to each other with the hydraulic means of lathe.
It also comprises fixed block, and fixed block is fixed on the bed piece, and described fixed block top is fixed on the outer surface of counterdie main body through trip bolt.Fixed block is connected with die holder on the bender workbench, plays the clamping mould.
Beneficial effect
Than prior art, the advantage of the utility model is:
(1) mould of use the utility model, in the bending process, the bikini of plate and counterdie main body contacts the cut that has reduced panel surface, has improved the surface quality of plate;
(2) mould of the utility model cooperates the location of push rod to control the bending angle of plate by the amount of moving down of patrix, but bending angle flexible makes this Bending Mould have more versatility;
(3) mould of use the utility model, the contact pressure between plate and the push rod can be controlled springback angle effectively, improves the plate bending precision;
(4) mould of use the utility model, after the bending process was accomplished, because push rod receives the upwards effect of hydraulic coupling, plate ejected groove under the effect of push rod, realize discharging quickly and easily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label declaration among the figure: 1-bending patrix 2-plate 3-counterdie main body 4-push rod 5-trip bolt 6-fixed block.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail.
Like Fig. 1, a kind of bikini Bending Mould of bending adjustable angle comprises bending patrix 1 and bending counterdie; Described bending counterdie comprises counterdie main body 3 and push rod 4, and push rod 4 links to each other with the hydraulic means of lathe.It also comprises fixed block 6, and fixed block 6 is fixed on the bed piece, and described fixed block 6 tops are fixed on the outer surface of counterdie main body 3 through trip bolt 5.
Embodiment 1
As shown in Figure 1, the Bending Mould of the utility model is made up of bending patrix 1, bending counterdie and fixed block 6.Wherein, the bending counterdie is made up of counterdie main body 3 and push rod 4, and push rod 4 links to each other with the hydraulic means of lathe.Fixed block 6 is fixed on the bed piece, and described fixed block 6 tops are fixed on the outer surface of counterdie main body 3 through trip bolt 5.
Use the mould of the utility model; When bending patrix 1 move down touch plate 2 after, along with the carrying out of bending process, the end face of two die ports and push rod 4 contacts about 2 of plates and counterdie main body 3; Because between plate 2 and the bending counterdie is 3 contacts; Contact area is little, has reduced the cut on plate 2 surfaces, has improved surface quality.Simultaneously, the bending angle of plate 2 can be controlled by the amount of moving down of bending patrix 1, thereby can bending goes out the plate 2 of different angles, has increased the versatility of this Bending Mould.
In whole bending process, the push rod 4 of bending counterdie receives the constant hydraulic coupling that radially makes progress that is applied by hydraulic means all the time, has a kind of contact pressure thereby make between plate 2 and the push rod 4.One of effect of this structure is the strain that reduces plate 2 crooked positions, improves its plastic deformation degree, thereby can control springback angle effectively, improves plate 2 bending precisions; Two of effect is after the bending process is accomplished, and plate 2 can play the effect of discharging at the push rod 4 effect ejection groove down of hydraulic coupling upwards.
