Detailed description of the invention

Referring to Fig. 1, mould for automobile door sill series products punching processing of the present invention is feature for a class automobile door sill class left member product, right member holes of products position and designs, the position, hole of this kind of automobile door sill class left member product (hereinafter referred to as left member), right member product (hereinafter referred to as right member) has quite a few to be identical, and the position, left end hole of left member is different from the position, right-hand member hole of right member.Mould of the present invention is made up of left end stamping-out station I, middle part stamping-out station II and right-hand member stamping-out station III, left end stamping-out station I and right-hand member stamping-out station III are at least respectively provided with place's cylinder switching mechanism, left member or right member according to workpiece, the cylinder switching mechanism switch operating of both mold ends.When processing left member, the cylinder switching mechanism of left end stamping-out station I enters duty, the cylinder switching mechanism of right-hand member stamping-out station III is deactivated state, rely on the assistance of the cylinder switching mechanism of left end stamping-out station I, under the driving of blanking equipment top shoe, jointly realized the punching processing of left member by the left end stamping-out station I of mould and middle part stamping-out station II; When processing right member, the cylinder switching mechanism of right-hand member stamping-out station III enters duty, the cylinder switching mechanism of left end stamping-out station I is deactivated state, rely on the assistance of the cylinder switching mechanism of right-hand member stamping-out station III, under the driving of blanking equipment top shoe, jointly realized the punching processing of right member by the middle part stamping-out station II of mould and right-hand member stamping-out station III.In sum, the present invention can adopt one set of die to complete the processing of two kinds of product piece.

Referring to Fig. 1, mould of the present invention comprises upper bolster 11, die shoe 2, upper mould fixed plate 9, holding pad 8, low mold frame 5, lower bolster 4 and lower bolster 3, and upper bolster connects the top shoe 12 of blanking equipment, and die shoe 2 is fixed on blanking equipment workbench 1.Upper mould fixed plate is fixedly connected with upper bolster through cushion block with bolt, and holding pad connects upper mould fixed plate; Low mold frame 5, lower bolster 4, lower bolster 3, die shoe 2 from top to bottom connect successively.

Be separately positioned on that left end stamping-out station I is identical with the cylinder switching mechanism principle of right-hand member stamping-out station III, vibrational power flow almost symmetry, just for position, the hole requirement of left member or right member, position or the quantity of drift adjust to some extent.Below in conjunction with accompanying drawing to be arranged on the cylinder switching mechanism of left end stamping-out station I, described mould is described in further detail.

Referring to Fig. 1, Fig. 2, Fig. 3, described cylinder switching mechanism comprises cylinder 16, thruster block 10 and drift 20, cylinder, thruster block between upper mould fixed plate and upper bolster, the affixed upper bolster of cylinder, cylinder rod connection side pushing block, is provided with thruster inclined-plane 10-1 bottom thruster block.Drift 20 is up big and down small stage structure, and drift upper end is provided with shoulder, and shoulder top is provided with truncated cone-shaped and presents a theatrical performance as the last item on a programme 20-1.Drift and upper mould fixed plate axis hole are slidably matched.On described holding pad 8, corresponding drift place is provided with bore of the punch, and low mold frame is provided with female die embedding cover 21, and female die embedding cover is corresponding with the upper-lower position of drift, and drift coordinates with female die embedding cover and realizes punching.Holding pad 8 is for compressing plate 7, and screw cover 18 is through upper mould fixed plate, and unloading bolt 17 is positioned at unloading bolt cover, and unloading bolt lower end is threaded with holding pad.Upper mould fixed plate 9 is provided with spring eye, and return spring 19 is arranged in spring eye, end stand and holding pad on difference contact spring hole, return spring upper and lower two ends.The scope that moves up and down of the relative upper mould fixed plate of holding pad is defined by screw cover, unloading bolt and return spring.Holding pad is also provided with the bore of the punch of corresponding forcer position.

Referring to Fig. 2, Fig. 4, for realizing punching guiding, be provided with guide pillar 15 and upper guide bush 14, lower guide pin bushing 13, upper guide bush 14, lower guide pin bushing 13 are coaxially arranged, the affixed upper mould fixed plate of guide pillar, and upper guide bush 14 is inlaid on holding pad, and lower guide pin bushing 13 is inlaid in low mold frame.Punch process, guide pillar and upper guide bush, lower guide pin bushing are slidably matched, so that drift accurately enters female die embedding cover.

Referring to Fig. 1, Fig. 2, Fig. 3, below to process left member, the course of work of the present invention is described: the cylinder switching mechanism of left end stamping-out station I is switched to duty, the cylinder switching mechanism of right-hand member stamping-out station III is deactivated state; The top shoe 12 of blanking equipment moves to the direction of plate 7 with dynamic air cylinder 16, thruster block 10, upper mould fixed plate 9, drift 20, holding pad 8 through upper bolster 11, until holding pad 8 contacts with sheet material 7 upper surface, now holding pad applies pressure to plate 7 under return spring 19 acts on; Cylinder 16 action, promote thruster block 10 and move right, drift 20 moves downward by after side-thrust, until the shoulder of drift upper end is clamped by thruster block 10 and upper mould fixed plate 9 simultaneously; Blanking equipment applies pressure, drives the drift of left end stamping-out station I and the drift action of middle part stamping-out station II, punching on plate, completes position, the hole processing of left member.After left member punching completes, the top shoe 12 of blanking equipment is with dynamic air cylinder 16, thruster block 10, upper mould fixed plate 9, drift 20 to move up through upper bolster 11, cylinder rod is regained, thruster block moves to left, under back-moving spring 19 acts on, holding pad is separated with upper mould fixed plate, and as shown in Figure 4, now left member can be taken out.

When Figure 5 shows that processing right member, left end stamping-out station I cylinder switching mechanism does not work, the schematic diagram of mold closed condition, and as seen from the figure, regain at non-operative end cylinder rod, thruster block and drift disengage, and drift can not the punching with the action of blanking equipment.

In the middle part of described mould, the forcer position of stamping-out station II is same holes position according to left member, right member and sets.During described Mould Machining right member, with processing left member process roughly the same, do not repeat herein.

The above-mentioned course of work of the present invention can have been coordinated by control device.

The above and accompanying drawing are that left end stamping-out station I of the present invention and right-hand member stamping-out station III respectively arrange a set of cylinder switching mechanism, often overlap the embodiment that cylinder switching mechanism arranges a drift.The present invention, when reality uses, can adjust position and the number of drift flexibly according to position, the hole processing request of left member or right member; Also can arrange multiple cylinder switching mechanism, driven the drift of processing position, different hole respectively by each cylinder switching mechanism, above-mentioned setting or similar improvement include within protection scope of the present invention.The present invention can also be applied to the other products part punching processing with part same holes position.
