Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing of embodiment below.
Fig. 1 is the structural representation of a kind of Pneumatic edge cutting device of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, an embodiment of the present utility model, a kind of Pneumatic edge cutting device, it comprises at least one trimming mechanism, and described trimming mechanism comprises and is arranged on cope match-plate pattern 1 above forcing press, is arranged on the lower bolster 2 below forcing press, the cutting die 3 be arranged on described cope match-plate pattern 1, the float support seat 4 be arranged on lower bolster 2; Described float support seat 4 is provided with and the locating mould cavity 41 needing trimming paper mould product 5 form fit, the blade of described cutting die 3 and the peripheral end of described locating mould cavity 41 just right; Air compressing chamber 42 is provided with between described lower bolster 2 and described float support seat 4; Described lower bolster 2 is provided with the air admission hole 21 communicated with described air compressing chamber 42, and described air admission hole 21 connects air-source.
During concrete enforcement, described cope match-plate pattern 1 or lower bolster 2 are connected with the matched moulds driving mechanism of forcing press.Described cope match-plate pattern 1 is provided with core rod 6 and outside plate 7; Described cutting die 3 is clamped between described core rod 6 and outside plate 7, and its blade stretches out towards described float support seat 4 direction.Described float support seat 4 comprises two cavitys, one is and the locating mould cavity 41 needing trimming paper mould product 5 form fit, this locating mould cavity 41 is positioned at float support seat 4 top, and another is 2-in-1 air compressing chamber 42 of enclosing formation with lower bolster, and this air compressing chamber 42 is positioned at float support seat 4 bottom.It should be noted that, owing to considering replacing and the maintenance problem of all parts, the upper end (one end namely towards the opposite with blade) of described core rod 6 is connected with lower bolster 2 by screw, changes core rod 6 to facilitate according to the paper mould product 5 of difformity or size.Described outside plate 7, cutting die 3 and core rod 6 are connected in turn by screw, carry out changing and keeping in repair after wearing and tearing to facilitate cutting die 3.
In order to prevent the Leakage Gas in air compressing chamber 42, between the contact surface of described lower bolster 2 and described float support seat 4, be provided with O-ring seal 8.Concrete, be provided with draw-in groove 43 bottom described float support seat 4; The upper end of described O-ring seal 8 is stuck in described draw-in groove 43, and its lower end is given prominence to described draw-in groove 43 and is connected with described lower bolster 2 by screw.In addition, while described float support seat 4 realizes being connected with lower bolster 2 by O-ring seal 8 and air compressing chamber 42 seals, the present embodiment also requires that sealing cushion rubber 8 has certain elasticity, and for providing certain decrement during matched moulds, this decrement scope can between 3 millimeters to 5 millimeters.
More preferably, the peripheral end of described locating mould cavity 41 is provided with the step 44 just right with the blade of described cutting die 3, described step 44 is provided with trimming backing plate 9, and this trimming backing plate 9 is detachable replacings, causes the phenomenon such as surperficial scratching, cutting die 3 tipping to prevent blade from touching float support seat 4.
During the present embodiment work, upper and lower mould is opened by the matched moulds driving mechanism of forcing press, the paper mould product 5 needing trimming is put in the locating mould cavity 41 of the float support seat 4 of counterdie, then upper and lower mould closes up by the matched moulds driving mechanism of forcing press, until when cutting die 3 just cuts paper mould product 5 upper surface, by locked for forcing press Up/down base position guarantee cope match-plate pattern 1 and lower bolster 2(and upper die and lower die) maintain static, now O-ring seal 8 is by compression 3 ~ 5 millimeters.Then the air admission hole 21 on lower bolster 2 passes into compressed air to air compressing chamber 42, its Stress control is in 0.4 to 0.6 MPa, at this moment under the effect of compacted O-ring seal 8, float support seat 4 pressurized plane (i.e. the top planes in air compressing chamber 42) forms air pressure, and the similar piston of float support seat 4 moves up 2 ~ 3 millimeters and cut off paper mould product 5 edge under compressed air effect.Visible, the utility model utilizes compressed air for power source, promote float support seat 4 paper mould product 5 of trimming moves by needing and cuts off edge by cutting die 3, when large table top more than one piece paper mould product 5 trimming, the requirement of table top and cutting die 3 cutting blade facial plane degree and parallelism precision can be met, effectively avoid occurring that paper mould product can't cut phenomenon; Utilize that Pneumatic pressure is adjustable, the compressible feature of gas simultaneously, prevent from producing excessive surge between cutting die 3 and trimming backing plate 9, ensure that the service life of cutting die 3.
In addition, the situation that the utility model is particularly suitable for large form, multi-mould uses simultaneously, on the one hand, avoid large form and require the too high and processing difficulties that causes in the depth of parallelism of whole stencil plane, on the other hand, the distortion avoiding the initiation of large form discontinuity is all irregular, thus has influence on the uneven problem of multi-mould trimming.And more trimming mechanism of the present utility model can overlap and be arranged on forcing press, its to the pressure requirements of forcing press without the need to very high, as long as can the weight of driving device own.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
