Abstract
The invention discloses a precision drilling anvil and relates to a bench and assembly hand tool. The precision drilling anvil comprises a punch and a shank, and is characterized in that the punch is provided with a point angle of 60 degrees +/-2 minutes by means of grinding on a universal tool grinder and the rod for processing the anvil is made of high-speed tool steel. The precision drilling anvil has the advantages that the service life of the anvil is prolonged, and the anvil is not easy to deviate from lines during dotting punch so that the punched dots processed by the anvil have regular shapes.
Description
Affiliated technical field
The present invention relates to a kind of pincers worker and assembling hand tools, especially a kind of precision drilling rushes with sample.
Technical background
Before pincers worker boring, first with sample, be punched on the center of circle and hit heart sample dotting punch, as boring, center.The precision of sample dotting punch directly determines the positional precision of holing.Current sample easily departs from lines while being punched in point, thereby causes positional precision not high; The out-of-shape of sample dotting punch, during boring, drill bit is not easy to aim at the center of circle, and the life-span of production efficiency and sample punching is all lower.
Summary of the invention
In order to solve, easily to depart from lines cause positional precision not high when existing sample is punched in dotting punch, when sample dotting punch out-of-shape causes boring, drill bit is not easy to aim at the problems such as the center of circle.The object of this invention is to provide a kind of precision drilling and rush with sample, and the punching of this sample can not only go out the sample dotting punch of regular shape, and when dotting punch, be not easy to depart from lines.The object of the invention is to realize by following technical scheme: a kind of precision drilling rushes with sample, comprise drift and shank, it is characterized in that drift partly adopts on the universal cutter grinder method of grinding to wear into the drift angle of 60 ° ± 2 ＇, the pole material of processing sample punching is high-speed tool steel.
Advantage of the present invention: owing to having adopted the method for grinding on universal cutter grinder, so the circularity of the manual sample punching grinding of the convexity ratio of drift part is high, thereby improves the circularity of sample dotting punch, and drill bit is easily aimed at sample dotting punch; Because drift has partly worn into 60.The drift angle of ± 2 ＇, makes its drift angle be less than drill bit 120.Drift angle, the drill bit auto-alignment center of circle in the time of can helping to hole; Due to the pole material selection high-speed tool steel of processing sample punching, the characteristic such as therefore have that red hardness is high, wearability good, intensity is high and grindability is good, sample rushes result of use and the life-span is improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of sample punching for a kind of precision drilling.
1. drifts, 2. shank in figure.
The specific embodiment
Fig. 1 is the structural representation of sample punching for a kind of precision drilling.Figure comprises drift and shank, it is characterized in that drift partly adopts on the universal cutter grinder method of grinding to wear into the drift angle of 60 ° ± 2 ＇, and the pole material of processing sample punching is high-speed tool steel.
Owing to having adopted the method for grinding on universal cutter grinder, so the circularity that the manual sample grinding of the convexity ratio of drift part rushes is high, thereby improves the circularity of sample dotting punch, makes drill bit easy aligning sample dotting punch when boring.
Because drift has partly been worn into the drift angle of 60 ° ± 2 ＇, make its drift angle be less than the drift angle of 120 °, drill bit, the drill bit auto-alignment center of circle in the time of can helping to hole.
Due to the pole material selection high-speed tool steel of processing sample punching, the characteristic such as therefore have that red hardness is high, wearability good, intensity is high and grindability is good, sample rushes result of use and the life-span is improved.
Claims (1)
1. a precision drilling rushes with sample, comprises drift and shank, it is characterized in that: drift partly adopts and on universal cutter grinder, wears into 60 ° ± 2 ' drift angle, the pole material of processing sample punching is high-speed tool steel.
