Abstract

The utility model discloses a punching cutter which is suitable for the mechanized punching of the honeycomb paperboard materials. The utility model comprises a long strip shaped cutter body; a plurality of saw teeth with various lengths are mounted on one side of the cutter body; the two inclined planes which form the saw teeth are shaped in slopes; the slopes are crossed on the top of the saw teeth to generate the subsidiary teeth. The punching cutter of the utility model solves the problems of continuous punching, rough hole edge and internal inclined hole edge etc., which are caused by the small hole punching or the irregular hole punching on the honeycomb paperboard materials. The punching cutter reduces the labor intensity and improves the safe coefficient and production efficiency.

Description

A kind of punching cutter

Technical field

The utility model relates to materials such as honeycomb cardboard is carried out punching cutter in the hole punched device of punching.

Background technology

In the past, honeycomb cardboard was not a very prosperous industry always, and the scale of the enterprise in this industry is all smaller usually, demand to honeycomb cardboard is also less, it all is hand labour basically that the postorder processing of honeycomb cardboard is handled, and labour intensity is big, and production efficiency is not high.In fact, because little to total demand of honeycomb paper, the amount of each batch is pitiably little especially, and the requirement that makes the postorder processing of honeycomb cardboard handle mechanization is not very urgent.Yet, along with the fast development of China's economy and country pay attention to day by day, obtained fast development as the honeycomb cardboard industry of ep-type material for environmental protection, a lot of manual operationss originally all or by mechanization produce substitute.Because the particularity of honeycomb cardboard material; it can be stepped down when stressed and the phenomenons such as jam of sticking, the chip of cardboard; make people when adopting general punching cutter to carry out towards aperture or irregular hole to honeycomb cardboard, through regular meeting occur dashing constantly, the limit, hole is rough, defective such as oblique in the limit, hole.Therefore, on materials such as honeycomb cardboard, offer aperture or irregular hole mainly still by manually finishing.The shortcoming of artificial perforate is: labour intensity is big, and production efficiency is low; Pass is lack of standardization, and the limit, hole is rough; Also cause personal injury etc. easily.

The utility model content

Technical problem to be solved in the utility model is: a kind of punching cutter applicable to material mechanical punchings such as honeycomb cardboards is provided.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of punching cutter comprises: the strip cutter hub, and a side of cutter hub is provided with several sawtooth different in size, two inclined-planes that form sawtooth are sloping shape, and intersect at the auxilliary tooth of top, formation of sawtooth.

All sawtooth are configured to that one is long and the other is short two kinds of sawtooth, and long tooth and short space of teeth are arranged.

The beneficial effects of the utility model are: the utility model is by being provided with sawtooth different in size, and each sawtooth all has auxilliary tooth, during work, long tooth at first contacts with cardboard, and in the incision cardboard, because the tooth pitch of two long teeth is bigger, cardboard is less to the resistance that it causes, thereby has avoided the generation that because of resistance excessive or cardboard distortion indent etc. can not the punching phenomenon; Simultaneously, bigger tooth pitch gap has given a Free up Memory of cardboard distortion, and along with the continuous incision of long tooth, joint-cutting constantly broadens, resistance increases gradually, when resistance increased to a certain degree, short tooth began to contact with cardboard, and the incision of this moment is quite smooth and easy, and the auxilliary tooth and hair of sawtooth top is waved effect, cut off the still cardboard filament of sticking connection, make cut surface smooth, played the effect of shaping.This punching cutter has solved well that materials such as honeycomb cardboard exist towards aperture or irregular hole the time dashes constantly, the limit, hole is rough, problem such as oblique in the limit, hole, has reduced labour intensity, has improved safety coefficient and production efficiency.

Among Fig. 1 to Fig. 3: 1, cutter hub, 2, long tooth, 21, long tooth inclined-plane, 22, long tooth inclined-plane, 3, short tooth, 31, short tooth inclined-plane, 32, short tooth inclined-plane, 4, auxilliary tooth, 5, auxilliary tooth.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of punching cutter described in the utility model comprises: strip cutter hub 1, a side of cutter hub 1 is provided with several long teeth 2 and short tooth 3, long tooth 2 and short tooth 3 arrange that at interval that is: long tooth 2 and long tooth 2 are non-conterminous, and short tooth 3 is non-conterminous with short tooth 3; Form long tooth 2 two inclined-planes 21 and 22 and two inclined-planes 31 and 32 of forming short tooth 3 all be sloping shape, and intersect at respectively long tooth 2 and short tooth 3 the top, form auxilliary tooth 4 and 5.

The utility model is by being provided with sawtooth different in size, that is: long tooth 2 and short tooth 3, and each sawtooth all has auxilliary tooth, that is: and the top that has auxilliary tooth 4, a short tooth 3, the top of long tooth 2 has and assists tooth 5.This punching cutter in the course of the work, long tooth 2 at first contacts with cardboard, and in the incision cardboard, because the tooth pitch of two long teeth 2 is bigger, cardboard is less to the resistance that it causes, and has avoided the generation that because of resistance excessive or cardboard distortion indent etc. can not the punching phenomenon; Simultaneously, bigger tooth pitch gap has given a Free up Memory of cardboard distortion, and along with the continuous incision of long tooth 2, joint-cutting constantly broadens, resistance increases gradually, when resistance increased to a certain degree, short tooth 3 beginnings contacted with cardboard, and the incision of this moment is quite smooth and easy, and the auxilliary tooth 4 and 5 of long and short tooth 2 and 3 tops plays a role, cut off the still cardboard filament of sticking connection, make cut surface smooth, played the effect of shaping.This punching cutter has solved well that materials such as honeycomb cardboard exist towards aperture or irregular hole the time dashes constantly, the limit, hole is rough, problem such as oblique in the limit, hole, has reduced labour intensity, has improved safety coefficient and production efficiency.

Claims (2)

1. punching cutter, comprising: the strip cutter hub is characterized in that: a side of described cutter hub is provided with several sawtooth different in size, two inclined-planes that form sawtooth are sloping shape, and intersect at sawtooth the top, form auxilliary tooth.

2. punching cutter as claimed in claim 1 is characterized in that: all sawtooth are configured to that one is long and the other is short two kinds of sawtooth, and long tooth and short space of teeth are arranged.
