Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of band compensates upper die of bending machine Quick mechanical clamping device, including intermediate plate 1, presses afterwards
Plate 2, regulating block 3, connecting plate 4, front pressuring plate 5 and eccentric shaft handle 14, intermediate plate 1 and regulating block 3 contact of incline plane, intermediate plate 1,
Regulating block 3 is fixing with connecting plate 4 respectively to be connected, and can be realized the deflection compensation of bending upper die by the position adjustment of regulating block 3；Before
Connected by fixing bolt 8 between pressing plate 5 and intermediate plate 1, fixing bolt 8 is cased with spring 2 10 and spheric washer 9, front pressuring plate
5 can globally packing ring 9 cambered surface rotate；Inclined-plane is processed in front pressuring plate 5 rear end, and by contour screw 6 and spring 1 and connecting plate
4 fixing connections；It is connected by clamping screw 15 between rear fender 2 with intermediate plate 1；Connecting plate 15 upper bottom portion center position is slotted
Being provided with needle bearing 12, front pressuring plate 5 rear end fluting is provided with eccentric shaft handle 14, and eccentric shaft handle 14 work surface is eccentric convex
The camber of wheels, eccentric shaft handle 14 is provided with for spacing locating dowel 13；Corresponding position peace on front pressuring plate 5 and rear fender 2
Equipped with rubber strip 16 and the movable panel 11 in bending upper die square groove can be snapped in；Operation by eccentric shaft handle 14
Realize the handling of bending upper die.Wherein, described locating dowel 13 can be flexibly positioned post, more convenient operation.
Wherein, the work surface of described eccentric shaft handle 14 and needle bearing 12 linear contact lay, pull eccentric shaft handle 14, pass through
Locating dowel 13 is spacing, and eccentric shaft handle 14 is in 90 ° with front pressuring plate 5, and front pressuring plate 5 front end is flared to fix with intermediate plate 1 grip orifice
Size, bending upper die inserts, and the movable panel 11 on front pressuring plate 5 clamping face snaps in the square groove of bending upper die automatically, prevents folding
Bending mould comes off；Pulling eccentric shaft handle 14, eccentric shaft handle 14 becomes 0 ° with front pressuring plate 5, and front pressuring plate 5 clamps face clamping bender
Tool, it is existing that the rubber strip that front pressuring plate clamping face is inlayed can prevent bending upper die clamping dimensional discrepancy from causing bending upper die clamping to loosen
As；During mould unloading, pull eccentric shaft handle 14, press locating dowel, make eccentric shaft handle 14 be more than 90 ° with front pressuring plate 5 angle, front pressure
Grip orifice flare up horn mouth between plate 5 and intermediate plate 1, it is simple to Bending Mould unloads.
Preferably, described clamping screw 15 is cased with back-moving spring, by tighten clamping screw 15 regulate rear fender 2 and in
Between jaws size between plate 1, it is achieved the clamping of rear fender 2.
Preferably, described intermediate plate 1 is connected by bolt is fixing with connecting plate 4, and regulating block 3 is by bolt and connecting plate 4
Fixing connection.
During work, as shown in Figures 2 and 3, the contour screw 6 installed in eccentric shaft handle 14 rear end and the effect of spring 7
Under, eccentric shaft handle 14 work surface and needle bearing 12 linear contact lay all the time.Pull eccentric shaft handle 14, when eccentric shaft handle 14 with
During front pressuring plate 5 angle α=0 °, eccentric shaft handle 14 work surface eccentric distance reaches maximum, front pressuring plate 5 globally packing ring 9 cambered surface
Rotate, make front pressuring plate 5 front end and intermediate plate 1 jaws size minimize value, now clamp bending upper die；Then eccentric shaft is pulled
Handle 14, locating dowel 13 positions, and 0 ° of ＜ α≤90 ° of angle between eccentric shaft handle 14 and front pressuring plate 5, eccentric shaft handle 14 works
Face eccentric distance diminishes, and front pressuring plate 5 front end and intermediate plate 1 jaws become large-sized, and bending upper die is at front pressuring plate 5 front end and intermediate plate
Loosening in 1 jaws, now the movable panel 11 of front pressuring plate 5 front end is stuck in bending upper die square groove, prevents bending upper die from coming off.Press
Lower locating dowel 13, pulls eccentric shaft handle 14, angle α ＞ 90 ° between eccentric shaft handle 14 and front pressuring plate 5, eccentric shaft handle 14
