It is fixed on lower tool apron 3.
As shown in Fig. 2, in the present embodiment, presser device includes positioned at 8 entrance side of upper tool post and mobile with upper tool post 8
Top board 7 and the lower platen 15 for being fixed on lower slide entrance side, 7 edge of top board extends to 6 entrance side of upper cutter head, lower platen 15
Edge extends to lower 3 entrance side of tool apron, and top board 7 is mobile with upper tool post 8, and strip is compressed or unclamped with shear action.
As depicted in figs. 1 and 2, in the present embodiment, 7 top surface of top board is symmetrically fixed at least two vertical guide rods
13,8 entrance side of upper tool post is equipped with the guide sleeve 11 cooperated with guide rod 13, and 13 top of guide rod stretches out guide sleeve 11 and is equipped with supporting plate 10,
Top board 7 separates rear upper tool post 8 with lower platen 15 when continuing to rise, and guide sleeve 11 drives guide rod 13 and top board 7 by supporting plate 10
Rise, be cased with spring 12 at least one guide rod 13, spring 12 is pressed between top board 7 and guide sleeve 11, top board 7 and pushing
When upper tool post 8 continues decline after plate 15 contacts, guide sleeve 11 is pressurizeed by spring 12 to top board 7, and the setting of presser device was both real
It is mobile with upper tool post 8 to have showed top board 7, and has played the role of pressurization, for the strip of different-thickness, compression effect is good, no
Strip can be destroyed.
As shown in Figures 2 and 3, in the present embodiment, on upper tool post 8, the root of card slot is widened small to outlet side
Groove, upper cutter head 6 at little groove using obtuse angle transition and not contacted with little groove, on lower slide, the root of card slot be to
The widened little groove of entrance side, lower tool apron 3 at little groove using obtuse angle transition and not contacted with little groove, using little groove and
The effect of obtuse angle transition, first is that prevent from being bonded it is overstocked, facilitate tool apron to be detached from card slot, second is that prevent when installation collsion damage tool apron and
Knife rest, using obtuse angle transition rather than arc transition, be easy for fabricating.
As shown in figure 3, in the present embodiment, 18 top of disc spring is covered with cover cylinder 21, pull rod 19 passes through cover cylinder 21, locking nut
17 are compressed cover cylinder 21 by improved mat 22, and cover cylinder 21 compresses disc spring 18, and cover cylinder 21 prevents locking nut 17 from directly acting on
In in disc spring 18, reducing the damage of disc spring 18, improved mat 22 ensure that the locking stability of locking nut 17.
As shown in figure 3, being fitted with wear-resistant sleeve 23 in the present embodiment, in through-hole, pull rod 19 cooperates in wear-resistant sleeve
In pipe 23, wear-resistant sleeve 23 avoids the abrasion of knife rest, improves the service life of knife rest；Wear-resistant sleeve 23 is equipped with several
Aperture, part of the pull rod 19 in wear-resistant sleeve 23 are equipped with annular groove, the effect of aperture and annular groove, generate first is that offsetting frictional heat generation
Thermal expansion, avoid blocking, second is that playing the role of heat dissipation.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
