Abstract
An upper and lower chamfering cutter is composed of a handle portion (1) and a blade portion (2), and is characterized in that a rough milling lower chamfering blade portion (2-2) is connected with a drilling blade portion (2-1); a section of cylinder blade portion is arranged between the rough milling lower chamfering blade portion (2-2) and the drilling blade portion (2-1); the rough milling lower chamfering blade portion (2-2) is a cone; the included angle B is 90 degrees. According to the upper and lower chamfering cutter, punching, rough milling and upper and lower chamfering can be completed at a time, the product machining precision is improved, the machining procedures are reduced, and the machining quality is improved.
Description
Technical field
The present invention relates to cutter manufacture technology, manufacture field, particularly relate to a kind of rose reamer up and down of cutter.
Background technology
Along with the development of machinery industry, the aspect such as delivery date and service life of user to the crudy of product, process reliability, working (machining) efficiency, cutter is proposed higher requirement.Current rose reamer is due to poor radiation, chip removal has some setbacks, the reasons such as environment for use is single, the development be out of step with the times, negative effect is caused to working (machining) efficiency and crudy, the particularly processing of some multiaspect chamferings, same exactly hole needs multiple operation, change multiple cutter to process it, this time is just high especially for requirement on machining accuracy, the particularly support processing of camera lens, when current process unit and tool sharpening, precision is not high, efficiency is also lower, yield rate is low, the performance having had a strong impact on whole product improves, therefore, design a kind of cutter of continuous chamfering, obvious advantage is had to raising processing precision of products and efficiency.
Summary of the invention
The object of the present invention is to provide a kind of rose reamer up and down, this upper and lower rose reamer can the multiple machined surface of chamfering continuously, is particularly suitable for the Continuous maching of thin-walled parts.
Technical scheme of the present invention is achieved in the following ways: a kind of rose reamer up and down, comprise shank and blade composition, blade is made up of chamfering blade, spiral guide angle on chamfering blade, coarse milling blade, coarse milling under blade of holing, coarse milling, it is characterized in that: under described described coarse milling, chamfering blade is connected with boring blade, one section of cylinder blade is provided with between chamfering blade and boring blade under coarse milling, under coarse milling, chamfering blade is cone, and angle is 90 degree.
The angle of described boring blade is 120 degree, makes locating hole use for follow-up coarse milling.
Described coarse milling blade is one section of cylinder cutting edge, and cutting edge external diameter is less than the cylinder external diameter under coarse milling between chamfering blade and boring blade.
On described coarse milling, chamfering blade is connected with coarse milling blade, and on coarse milling, chamfering blade is a cone, and cone head diameter is equal with coarse milling blade cylinder external diameter, and on coarse milling, chamfering blade cone angle is 90 degree.
Described blade along head to coarse milling on chamfering blade cone root be provided with spiral guide angle, spiral guide angle angle is between 40-50 degree.
The present invention, because blade is provided with continuous multiple processing blade, disposablely can complete punching, rough mill and upper and lower chamfering, improve processing precision of products, decrease manufacturing procedure, improve crudy.
Accompanying drawing explanation
Fig. 1 is a kind of rose reamer structural representation up and down of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
In figure: 1 shank, 2 blades, 2-1 hole blade, chamfering blade, 2-5 spiral guide angle on chamfering blade, 2-3 coarse milling blade, 2-4 coarse milling under 2-2 coarse milling.
Detailed description of the invention
By Fig. 1, Fig. 2 knows, a kind of rose reamer up and down, by shank 1, blade 2, boring blade 2-1, chamfering blade 2-2 under coarse milling, coarse milling blade 2-3, chamfering blade 2-4 on coarse milling, spiral guide angle 2-5 forms, the included angle A of described boring blade 2-1 is 120 degree, make locating hole for follow-up coarse milling to use, under described coarse milling, chamfering blade 2-2 is connected with boring blade 2-1, one section of cylinder blade is provided with between chamfering blade 2-2 and boring blade 2-1 under coarse milling, under coarse milling, chamfering blade 2-2 is cone, included angle B is 90 degree, described coarse milling blade 2-3 is one section of cylinder cutting edge, cutting edge external diameter is less than the cylinder external diameter under coarse milling between chamfering blade 2-2 and boring blade 2-1, on described coarse milling, chamfering blade 2-4 is connected with coarse milling blade 2-3, on coarse milling, chamfering blade 2-4 is a cone, cone head diameter is equal with coarse milling blade 2-3 cylinder external diameter, on coarse milling, chamfering blade 2-4 cone angle C is 90 degree, described blade 2 along head to coarse milling on chamfering blade 2-4 cone root be provided with spiral guide angle 2-5, spiral guide angle 2-5 angle is between 40-50 degree, during use, boring blade 2-1 carries out bore operation to workpiece, the die cavity of coarse milling blade 2-3 to boring rough mills out basic appearance and size, then by chamfering blade 2-2 under coarse milling, lower chamfering operation is carried out to the hole of rough milling, by chamfering blade 2-4 on coarse milling, upper chamfering operation is carried out to the hole of rough milling again, the metal fillings be finally processed to form is discharged by spiral guide angle 2-5, prevent the shaping process that is drilled in from producing putty, reduce blade 2 and add the temperature produced man-hour, extend shaping brill service life, improve crudy.
