Upper mould fixed plate Jing cushion blocks are fixedly connected upper bolster, holding pad connection upper mould fixed plate with bolt；Low mold frame 5, lower bolster 4, under
Template 3, die shoe 2 are from top to bottom sequentially connected.
Be separately positioned on left end punching station I and right-hand member be punched station III cylinder switching mechanism principle is identical, structure sets
Almost symmetry is put, requires that the position of drift or quantity have been adjusted just for the hole position of left member or right member.Below in conjunction with accompanying drawing
As a example by being arranged on the cylinder switching mechanism of left end punching station I, the mould is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3, the cylinder switching mechanism includes cylinder 16, side pushing block 10 and drift 20, and cylinder, side push away
Block is located between upper mould fixed plate and upper bolster, and the affixed upper bolster of cylinder, cylinder rod connecting side pushing block, side pushing block bottom are provided with side
Push away inclined-plane 10-1.Drift 20 is up big and down small stage structure, and drift upper end is provided with shoulder, is provided with truncated cone-shaped and presents a theatrical performance as the last item on a programme at the top of shoulder
20-1.Drift is slidably matched with upper mould fixed plate axis hole.Bore of the punch is provided with correspondence drift on the holding pad 8, low mold frame sets
There is female die embedding cover 21, female die embedding cover is corresponding with the upper-lower position of drift, drift is coordinated with female die embedding cover realizes punching.Holding pad 8
For compressing plate 7, screw set 18 passes through upper mould fixed plate, unloading bolt 17 to be located in unloading bolt set, unloading bolt lower end
It is threadedly coupled with holding pad.Upper mould fixed plate 9 is provided with spring eye, and return spring 19 is arranged in spring eye, and return spring is upper and lower
End stand and holding pad on the difference contact spring hole of two ends.Define that holding pad is relative by screw set, unloading bolt and return spring
The up and down motion scope of upper mould fixed plate.The bore of the punch of correspondence forcer position is additionally provided with holding pad.
Referring to Fig. 2, Fig. 4, it is to realize that punching is oriented to, is provided with guide pillar 15 and upper guide bush 14, lower guide pin bushing 13, upper guide bush 14,
Lower guide pin bushing 13 is coaxially disposed, and the affixed upper mould fixed plate of guide pillar, upper guide bush 14 are inlaid on holding pad, and lower guide pin bushing 13 is inlaid in lower mould
On frame.Punch process, guide pillar are slidably matched with upper guide bush, lower guide pin bushing, so that drift accurately enters female die embedding cover.
Referring to Fig. 1, Fig. 2, Fig. 3, the course of work of the present invention below as a example by processing left member, is illustrated：Left end is punched into work
The cylinder switching mechanism of position I switches to working condition, and the cylinder switching mechanism of right-hand member punching station III is deactivated state；Punching
12 Jing upper bolsters of sanction equipment top shoe 11 drive cylinder 16, side pushing block 10, upper mould fixed plate 9, drift 20, holding pad 8 to plate 7
Direction movement, until holding pad 8 and 7 upper surface of sheet material, now holding pad is applied to plate 7 under the effect of return spring 19
Plus-pressure；16 action of cylinder, promotes side pushing block 10 to move right, and drift 20 is moved downward after receiving side-thrust, until drift upper end
Shoulder simultaneously clamped on upper mould fixed plate 9 by side pushing block 10；Blanking equipment applies pressure, drives rushing for left end punching station I
Head is punched the drift action of station II with middle part, and the punching on plate completes the hole position processing of left member.After the completion of left member punching,
12 Jing upper bolsters of blanking equipment top shoe 11 drive cylinder 16, side pushing block 10, upper mould fixed plate 9, drift 20 to move up, cylinder
Bar withdraws, and side pushing block is moved to left, and in the case where back-moving spring 19 is acted on, holding pad is separated with upper mould fixed plate, as shown in figure 4, now left
Part can be taken off.
When Fig. 5 show processing right member, left end punching station I cylinder switching mechanisms do not work, mold closed condition shows
It is intended to, as seen from the figure, withdraws in non-operative end cylinder rod, side pushing block is disengaged with drift, and drift will not be with blanking equipment
Action and punching.
In the middle part of the mould be punched station II forcer position be according to left member, the identical hole position of right member and set.It is described
It is during mould processing right member, similar with the process of processing left member, do not repeat herein.
The above-mentioned course of work of the present invention can be coordinated to complete by control device.
The above and accompanying drawing are that left end of the present invention is punched station I and right-hand member punching station III respectively arranges a set of cylinder and cuts
Converting mechanism, the embodiment for often covering cylinder switching mechanism one drift of setting.The present invention when actually used, can according to left member or
The hole position processing request of right member is adjusted flexibly position and the number of drift；Multiple cylinder switching mechanisms can also be set, by each
Cylinder switching mechanism drives the drift of the different hole positions of processing, above-mentioned setting or similar improvement to be included in protection of the invention respectively
Within the scope of.The present invention can also be applied to the other products part punching processing with the identical hole position in part.
