Abstract
A kind of square hole punching cutter head, described cutter head is rectangular structure, one end of described cutter head is for arranging bevelled punching end, described punching end is provided with arc groove at the incline direction along inclined-plane, described arc groove is provided with and is no less than two, the inclined-plane of described punching end is rearranged by described arc groove, and described arc groove connects between two and form fin on described inclined-plane, and described fin is higher than the incline of described punching end the right and left.The utility model proposes one, to be punching into power high, reduces the square hole punching cutter head that square-tube-shaped transformation is flat.
Description
Technical field
The utility model relates to punching cutter technical field, particularly relates to a kind of square hole punching cutter head.
Background technology
The existing punching cutter for piercing on rectangular tube, its punching end is generally the plane knife edge, realizes punching by downward punching press to square tube, when perforating press high speed stamping, the lifting surface area of square tube moment is larger, if when square tube thickness is crossed thin, the deformation power that sidewall is subject to far is more than within the scope of the receivable deformation recovery of square tube, easily occurs breaking or Dish deformation, be punching into power lower, the percent defective produced is higher, and punching quality is low, and production efficiency is low.
Summary of the invention
It is high that the purpose of this utility model is that proposition one is punching into power, reduces the square hole punching cutter head of square tube deformation.
For reaching this object, the utility model by the following technical solutions:
A kind of square hole punching cutter head, described cutter head is rectangular structure, one end of described cutter head is for arranging bevelled punching end, described punching end is provided with arc groove at the incline direction along inclined-plane, described arc groove is provided with and is no less than two, the inclined-plane of described punching end is rearranged by described arc groove, and described arc groove connects between two and form fin on described inclined-plane, and described fin is higher than the incline of described punching end the right and left.
Preferably, the difference in height of described fin and described incline is no less than 1mm.
Preferably, described cutter head is installed on punch mechanism by bolt.
Preferably, the material of described cutter head is iron and steel.
Preferably, described arc groove is provided with two.
The beneficial effects of the utility model: the setting of punching point make square tube to be punching into power high, reduce the waste to square tube, form complete punching.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the structural representation of an embodiment of the present utility model.
Wherein: cutter head 1, punching end 11, arc groove 111, fin 112, incline 113, punching point 114, incline punching point 115.
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.
As shown in Figure 1 or 2, a kind of square hole punching cutter head, described cutter head 1 is rectangular structure, one end of described cutter head 1 is for arranging bevelled punching end 11, described punching end 11 is being provided with arc groove 111 along the incline direction on inclined-plane, described arc groove 111 is provided with and is no less than two, the inclined-plane of described punching end 11 is rearranged by described arc groove 111, described arc groove 111 connects between two and form fin 112 on described inclined-plane, and described fin 112 is higher than the incline 113 of described punching end 11 the right and left.
The inclined-plane of punching end 11 is rearranged by arc groove 111, arc groove 111 forms the fin 112 higher than the right and left incline on inclined-plane, the utility model square hole punching cutter head is installed on perforating press, punching end 11 carries out lower punching perforation towards square tube, due to the setting of fin 112, be combined with inclined-plane and define punching point 114, when punching is carried out to square tube, the punching point 114 of cutter head 1 first acts on piercing on rectangular tube face, the punch side wearing square tube is first rushed by the punching point 114 be arranged in the middle part of punching end 11 cutting edge, carry out punching wear and locate, rushing point 115 by the incline of both sides again acts on the punch side of square tube, be provided with multiple punching stress point, the lifting surface area of square tube moment is less, the deformation produced is in the scope recovered of square tube, so it is high to be punching into power, reduce the waste to material, in addition, the incline 113 of fin 112 specific impulse nose end 11 the right and left is high, first carry out punching to the middle part of position, hole to wear, if when wearing two ends, position, hole subpunch when square hole length is shorter, easily occur with its sidewall in the middle part of position, square tube hole caving in or flattening, cause punching failure.The cutter head of punching point is not set in prior art, during punching, because the area of the stress and deformation of square tube moment is large, the sidewall easily deformation by punching press of square tube, cause punching unsuccessful, square tube need reclaim reprocessing, punching quality and efficiency low.
Preferably, described fin 112 is no less than 1mm with the difference in height of described incline 113.Difference in height is no less than 1mm, and the punching point being positioned at fin 112 just can better play the effect of rushing and wearing and locating.
Preferably, described cutter head 1 is installed on punch mechanism by bolt.Installed by Bolt to position, can arbitrarily be installed on different punch mechanisms, easy accessibility.
Preferably, the material of described cutter head 1 is iron and steel.Iron and steel saw lumber handling ease, long service life, produces easy.
Preferably, described arc groove 111 is provided with two.According to the size of existing processing square hole size, be generally provided with two arc grooves 111 on inclined-plane and can meet crudy demand, make it have simpler structure and ornamental.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
