Abstract
The utility model provides a non-standard lettering knife. The non-standard lettering knife comprises a knife body, wherein the diameter of the knife body is 6 millimeters, the diameter of the knife point is 1 millimeter, the length of the knife body is 60 millimeters, the length of the cutting edge is 20 millimeters, the angle of the cutting edge and an abdicating angle of the knife body are between 9 degrees and 10 degrees, and the angle of the knife point is 5 degrees. The non-standard lettering knife can be used to carve marks on a large-scale forging mould cavity at a position where the depth is more than 50 millimeters and the width is less than 20 millimeters. The blank of the lettering knife is an alloyed tool steel bar. The non-standard lettering knife is manufactured through grinding procedures such as taper machining of the bar, halving of the bar, cutting edge grinding, knife point grinding and abdicating machining. The non-standard lettering knife has the advantages of being low in cost and long in service life.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of nonstandard carver.
Background technology
Forging product is more and more higher to the requirement of permanent identification at present, and client is very strict to font size, the degree of depth and sign display position thereof.The large-sized forging mould structure is complicated at present, and the position die cavity of carving characters is dark, and width is little, and standard cutter often occur breaking in the process, and cost is high, can not meet the demands.
Summary of the invention
The purpose of this utility model provides a kind of nonstandard carver, can realize that the dark narrow class mould blaze of large-sized forging mould knows disposable processing, and the cost of charp tool is low, and the life-span is high.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: nonstandard carver, comprise cutter hub, it is characterized in that: the diameter of described cutter hub is 6mm, the diameter of point of a knife is 1mm, and the length of cutter hub is 60mm, and the length of cutting edge is 20mm, the blade angle of cutter hub and empty avoiding angle are 9～10 °, and the angle of point of a knife is 5 °.
Beneficial effect:
Use nonstandard carver described in the utility model, can be used in the large-sized forging mould cavity depth greater than 50mm, width is known less than 20mm position blaze.The cutter blank is the alloy tool steel bar, during manufacturing, by bar worn into tapering, opened half, cutting edge, point of a knife, empty avoiding etc. grind operation and realize.It is low that cutter has a cost, the advantage that the life-span is high.
