Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The utility model provides a kind of diel cam mechanism protective device, for protecting the cam mechanism of mould during punching press, as Figure 1-5, this device comprises and is positioned at patrix drive block 1 and is provided with the first wearing plate 3 and the second wearing plate 4, first wearing plate 3 and the second wearing plate 4 stagger and arrange, and namely both are non-intersect; Being positioned at counterdie drives slide block 2 to be provided with the 3rd wearing plate 5 and the 4th wearing plate 6, same 3rd wearing plate 5 and the 4th wearing plate 6 also stagger setting, and the 3rd wearing plate 5 and corresponding with the first wearing plate 3 and the second wearing plate 4 respectively setting of the 4th wearing plate 6, namely the 3rd wearing plate 5 can contact with the first wearing plate 3, and the 4th wearing plate 6 can contact with the second wearing plate 4;
The drive block 1 of the present embodiment can move downward relative to driving slide block 2, when moving downward, the first wearing plate 3 on drive block 1 first contacts with the 3rd wearing plate 5 driven on slide block 2 and is separated afterwards, and promote to drive slide block 2 to move in contact process, meanwhile, drive block 1 drives the second wearing plate 4 to move to the 4th wearing plate 6 and contacts completely, namely first the first wearing plate 3 first contacts with the 3rd wearing plate 5 driven on slide block 2, now the second wearing plate 4 does not contact with the 4th wearing plate 6, along with drive block 1 continue move downward, first wearing plate 3 can be shifted onto and drive slide block 2 to move a segment distance, in motion process, second wearing plate 4 gradually moves to the 4th wearing plate 6 and starts contact, now drive block 1 continues to move downward, second wearing plate 4 starts to shift the 4th wearing plate 6 onto and promotes further to drive slide block 2 to move, now the first wearing plate 3 is separated gradually with the 3rd wearing plate 5, namely above-mentioned said first wearing plate 3 first contacts with the 3rd wearing plate 5 and is separated afterwards, second wearing plate 4 moves to the 4th wearing plate 6 and contacts completely.
As the preferred technical scheme of one, first wearing plate 3 and the second wearing plate 4 are inclined on drive block 1, and the first wearing plate 3 is 15 °-25 ° with the angle of the vertical plane of drive block 1,20 ° are preferably in the present embodiment, second wearing plate 4 is 35 °-45 ° with the angle of the vertical plane of drive block 1, is preferably 40 °.
Corresponding, 3rd wearing plate 5 and the first wearing plate 3 be arranged in parallel, 4th wearing plate 6 and the second wearing plate 4 be arranged in parallel, namely the 3rd wearing plate 5 and the 4th wearing plate 6 are also be arranged on driving slide block 2 in what tilt, angle of inclination is identical with the first wearing plate 3 and the second wearing plate 4, and then achieve the first wearing plate 3 and contact with the 4th the seamless of wearing plate 6 with the 3rd wearing plate 5, second wearing plate 4, improve buffering effect during contact.
As preferably, at drive block 1 and drive on slide block 2 and be equipped with connecting plate, the first wearing plate 3 and the second wearing plate 4 are fixed on the connecting plate of drive block 1, the 3rd wearing plate 5 and the 4th wearing plate 6 be fixed on drive slide block 2 connecting plate on.It should be noted that drive block 1 and drive the size of the connecting plate on slide block 2 not identical only need meet and can fix above-mentioned respective wearing plate.
Below detailed process principle of the present utility model is illustrated:
Originally, as shown in Figure 3, in the process that the drive block 1 of patrix down moves, the first wearing plate 3 has just started to contact with the 3rd wearing plate 5, now, also has certain distance between the second wearing plate 4 and the 4th wearing plate 6;
As shown in Figure 4, the drive block 1 of patrix continues down to move, and now the first wearing plate 3 and the 3rd wearing plate 5, second wearing plate 4 and the 4th wearing plate 6 are all in contact condition.The effect that the driving slide block 2 of counterdie contacts (namely the first wearing plate 3 promotes the 3rd wearing plate 5) due to the first wearing plate 3 with the 3rd wearing plate 5 in this process has moved right a segment distance, and the second wearing plate 4 starts to contact with the 4th wearing plate 6;
Subsequently, as shown in Figure 5, the drive block 1 of patrix moves to extreme position and overwhelms dead point, after the second wearing plate 4 contacts with the 4th wearing plate 6, the motion of the driving slide block 2 of counterdie starts to promote the 4th wearing plate 6 by the second wearing plate 4 and realizes, first wearing plate 3 is separated gradually with the 3rd wearing plate 5, until be finally separated completely.
In above process, owing to first promoting the 3rd wearing plate 5 by the first wearing plate 3, driving slide block 2 is moved a segment distance, driving slide block 2 is made to have had an initial velocity, promote the 4th wearing plate 6 by the second wearing plate 4 more afterwards to move to make driving slide block 2, whole process can reduce drive block 1 to driving the shock of slide block 2, also prevent cam mechanism stressed excessive and damage in motion process.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
