Referring to Figure 16 and Figure 17, the hydraulic combined punching & shearing machine of the present embodiment, including a knife plate matching mechanism for seedlings, knife plate matching The core of mechanism is knife plate matching eccentric shaft 6, and it is same that the knife plate matching eccentric shaft 6 sets gradually outer stationary plates 61, first Heart section 63, the second eccentric segment 64 and third concentric segments 65, knife plate matching eccentric shaft 6 cross fuselage 1, offer on outer stationary plates 61 Fixed plate screw hole 62, outer stationary plates 61 are inserted into fixed plate screw hole 62 by bolt and are fixed with the wallboard of fuselage 1.The present embodiment Knife plate match eccentric shaft 6, as the term suggests i.e. outer stationary plates 61, the first concentric segments 63 and third concentric segments 65 be it is concentric, second Eccentric segment 64 and other three sections of all decentractions, eccentric distance are eccentric according to the knowhow of inventor depending on different situations 2mm is generally attained by requirement.

The core design thought of knife plate matching eccentric shaft 6 is that moving knife knife plate is made to pass through a connecting plate and knife in the present embodiment The second eccentric segment 64 that plate matches eccentric shaft 6 is connected, and so rotates knife plate and matches eccentric shaft 6, may make moving knife knife plate with one Oval radian rotation, rather than round radian rotation, rotation can guarantee that moving knife knife plate and quiet knife knife plate reach in this way To location matches, and then the edge of a knife of moving knife and quiet knife can also reach matching.Because the processing dimension of moving knife and quiet knife is often all It is accurate and match each other, as long as knife plate reaches location matches, then being also not required in the case where replacement moving knife and quiet knife below Other adjustment are done again, so the use of knife plate provided in this embodiment matching eccentric shaft 6 being the method put things right once and for all, adjusted After primary, behind again more allowing blade replacement when, non-matching phenomenon will be less prone to, greatly facilitates the use of client.

The knife plate matching eccentric shaft 6 of the present embodiment is generally there are two types of design method, one is in the punching and shearing machine process segment, After moving knife knife plate and quiet knife knife plate have installed, eccentric shaft 6 is matched by rotation knife plate and makes moving knife knife plate and quiet knife knife plate Reach location matches, then the aperture on the wallboard of fuselage 1, knife plate matching eccentric shaft 6 is fixed.After punching and shearing machine factory, client Moving knife plate matching eccentric shaft 6 is not needed again more allowing blade replacement yet.

Another kind is will to be set as detachable structure between outer stationary plates 61 and the first concentric segments 63, such as outer stationary plates 61 and One concentric segments 63 are connected through a screw thread.So, it is ensured that during client uses punching and shearing machine, in order to reach edge of a knife matching mesh , need to rotate again knife plate matching eccentric shaft 6 make moving knife knife plate and quiet knife knife plate reach location matches (such situation is small general Rate event).At this point, although the fixed plate screw hole 62 opened up on outer stationary plates 61 cannot be overlapped with aperture on the wallboard of fuselage 1, Still, to achieve the purpose that fixed knife plate matching eccentric shaft 6, biggish warp can will not be brought to client by replacing outer stationary plates 61 Ji loss.

Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution Similar frame mode and embodiment, are within the scope of protection of the invention.
