Abstract
The invention relates to a wide-line processing indexable bulb milling cutter for a mould, and is used for solving the problem that the processing efficiency of the conventional bulb milling cutter is low when opening small-curvature moulds such as automobile covering part skylight convex-concave moulds are processed. The wide-line processing indexable bulb milling cutter provided by the invention comprises a body, wherein the body is provided with four cutting edges, and the four cutting edges are a cutting edge I (1), a cutting edge II (5), a cutting edge III (7) and a cutting edge IV (11); each cutting edge is respectively provided with a front tool surface (12), a front tool surface (17), a front tool surface (8), a front tool surface (19) and a rear tool surface (18), a rear tool surface (4), a rear tool surface (15) and a rear tool surface (10), and the front tool surface (12), the front tool surface (17), the front tool surface (8) and the front tool surface (19) are adjacent to the cutting edge; transition parts of an upper surface (3) of the body and the front tool surface (8) and the front tool surface (12) are respectively an inclined surface (6) and an inclined surface (2), and transition parts of a lower surface (3) of the body and the front tool surface (17) and the front tool surface (19) are an inclined surface (16) and an inclined surface (13). The wide-line processing indexable bulb milling cutter provided by the invention is used for a cutter for machining.
Description
technical field:
the present invention relates to a kind of mould and process indexable rose cutter with wide row, be specifically related to a kind of Mould Machining special efficient milling cutter.
background technology:
at present multiplex in the fine finishining for car large-scale covering mould is a kind of clip type rose cutter of single centre of sphere, in this kind of tool sharpening process, its processing mode is the processing of some contact narrow row, and place, rose cutter summit linear velocity is zero, make Tool in Cutting inclement condition, exist the low and crudy of lathe efficiency not allow manageable shortcoming.If when the uncovered class small curve moulds such as processing automobile covering skylight punch-die, adopt conventional rose cutter working (machining) efficiency very low.And the rose cutter cutter adopting is non-indexing type, after event of blade failure, need to reface, or can not use, and has increased the use cost of cutter, has reduced working (machining) efficiency.
summary of the invention:
the object of the present invention is to provide a kind of mould to process indexable rose cutter with wide row.
the object of the present invention is achieved like this:
a kind of mould is processed indexable rose cutter with wide row, body, described body has four cutting edges, four described cutting edges are cutting edge one, cutting edge two, cutting edge three, cutting edge four, cutting edge described in each has respectively the rake face one adjacent with cutting edge described in this, rake face two, rake face three, rake face four and rear knife face one, rear knife face two, rear knife face three, rear knife face four, the upper surface of described body respectively with described rake face one, the transition portion of described rake face three is Yi He inclined-plane, inclined-plane two, the lower surface of described body respectively with described rake face two, described rake face four transition portions are San He inclined-plane, inclined-plane four.
described mould is processed indexable rose cutter with wide row, in the middle of described body, has trip bolt hole, and described body is connected with corresponding knife bar by trip bolt.
described mould is processed indexable rose cutter with wide row, and described cutting edge is circular arc, and every adjacent described cutting edge has two different centers of circle, and centre is straight sword, and described cutting edge has blunt round structure.
beneficial effect:
1. rose cutter bulb of the present invention partly adopts two centre of sphere structures, can avoid the narrow row of rose cutter point contact in the past to process the problems such as the working (machining) efficiency causing is low, machined surface quality is uncontrollable.
the present invention adopts indexable formula structure, has four cutting edges, than the mould fine finishining rose cutter of current use many two cutting edges, the quantity of cutting edge is current 2 times, service life be current 2-3 doubly, working (machining) efficiency increases exponentially.
in the middle of two centre ofs sphere of rose cutter of the present invention, adopt vertical cut to cut tooth shape formula, having weakened rose cutter apex lines speed is the zero impact on cutter life reduction and surface quality variation in process.
accompanying drawing explanation:
accompanying drawing 1 is front view of the present invention.
accompanying drawing 2 is side views of the present invention.
accompanying drawing 3 is rearviews of the present invention.
accompanying drawing 4 is cutaway views of the present invention.
the specific embodiment:
embodiment 1:
a kind of mould is processed indexable rose cutter with wide row, its composition comprises: body, described body has four cutting edges, four described cutting edges are cutting edge one (1), cutting edge two (5), cutting edge three (7), cutting edge four (11), four described cutting edges have respectively the rake face one (12) being adjacent, rake face two (17), rake face three (8), rake face four (19) and rear knife face one (18), rear knife face two (4), rear knife face three (15), rear knife face four (10), the upper surface of described body (3) respectively with the rake face three (8) of described body, rake face one (12) transition portion is inclined-plane one (6) and inclined-plane two (2), the lower surface of described body (14) respectively with the rake face two (17) of described body, the transition portion of rake face (19) four is inclined-plane three (16) and inclined-plane four (13).
embodiment 2:
according to the mould described in embodiment 1, with wide row, process indexable rose cutter, in the middle of described body, have trip bolt hole (9), described body is connected with corresponding knife bar by trip bolt.
embodiment 3:
according to the mould described in embodiment 1 or 2, with wide row, process indexable rose cutter, described cutting edge is circular arc, and every adjacent described cutting edge has two different centers of circle, and centre is straight sword, and described cutting edge has blunt round structure.
Claims (3)
