Description
Technical field
It the utility model is related to punching cutter correlative technology field, and in particular to a kind of Novel angle iron punching cutter.
Background technology
In angle steel production process, the punching of diagonal steel uses punching cutter, and pressing equipment is arranged on using fixture
It is upper to coordinate completion task with lower mould.
But in actual applications, the most prominent part in existing edge of a knife section is sharp angle-style, is connect at first in work
Touch by the angle steel of punching, but the position often forms stress concentration so that the spoilage of the edge of a knife is very because being excessively sharp
Height, how long often have more than is needed will crumble, and edge of a knife service life is short.
A kind of existing angle steel punching cutter, can cause the service life of the edge of a knife to lengthen.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided a kind of extension edge of a knife service life
Novel angle iron punching cutter.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of Novel angle iron punching cutter, it is characterised in that described including point of a knife part, blade part and knife portion
Point of a knife part in the forefront position of whole cutter, blade part is in the middle part of cutter, two sides of point of a knife part and knife
The side of body part two is angled and triangular shape, point of a knife part are the edge of a knife in most ledge, and the described edge of a knife is
Arc-shaped, blade part is rectangular shape and the other end is knife portion, and knife portion thickness ratio blade part is small, knife afterbody
The position for dividing thickness small forms neck.
Preferably, described angle steel punching cutter thickness is that 32 mm lengths are 143.75 millimeters, and knife portion neck is thick
Spend for 3 millimeters.
The utility model has the advantage that：
Point of a knife acute angle is changed to arc-shaped, avoids point of a knife stress concentration, extends edge of a knife service life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model angle steel punching cutter；
Fig. 2 is the utility model side view；
Fig. 3 is the partial schematic diagram of the edge of a knife.
Embodiment
The utility model is further described with reference to embodiment, but the scope of protection of the utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1 Fig. 2, a kind of Novel angle iron punching cutter, it is characterised in that including point of a knife part 1, blade portion
Points 2 and knife portion 3, described point of a knife part 1 in the forefront position of whole cutter, blade part 2 in the middle part of cutter,
Knife portion 3 is at the last position of cutter.Two sides of point of a knife part 1 are angled with the side of blade part two and in three
Angular shape, point of a knife part are the edge of a knife 11 in most ledge,
With reference to shown in Fig. 3, the described edge of a knife 11 is arc-shaped, and such arc-shaped can avoid the stress concentration feelings of the edge of a knife
Condition so that the edge of a knife will not damage easily in use, extend the service life of the edge of a knife.
Blade part 2 is rectangular shape and the other end is knife portion 3, and the thickness ratio blade part of knife portion 3 is small, knife
The small position of portion thickness forms neck 31, and neck causes whole cutter to may be mounted on pressing equipment.Angle steel punching
Cutter thickness is that 32 mm lengths are 143.75 millimeters, and knife portion neck thickness is 3 millimeters.
When angle steel punching cutter works, first by whole Cutting tool installation manner to pressing equipment, coordinate and coordinate diagonal steel with lower mould
Punching work is carried out, in punching, the edge of a knife of point of a knife part contacts by the angle steel of punching at first, and this practical edge of a knife is circular arc
Shape, such arc-shaped can avoid the stress concentration of the edge of a knife so that the edge of a knife will not damage easily in use, prolong
The service life of the edge of a knife is grown.
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to above-mentioned each embodiment it is detailed
Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced
Change, and all do not depart from technical scheme and its improvement of spirit and scope of the present utility model, it all should cover new in this practicality
In the right of type.
