Description
Technical field
The utility model belongs to automatic lathe turning technical field, and in particular to a kind of large size steel part heavy duty roughing vehicle
Knife.
Background technique
Lathe tool is for most widely used in turnery processing, the cutter with cutting tip and machining
One of cutter can be used on various lathes, processing excircles, inner hole, end face, screw thread, recessing etc., and when needs are to large-scale steel part
When material is processed, it is necessary to process is completed with lathe tool using heavily loaded roughing, still, present heavily loaded roughing
Lathe tool when in use, since main cutting edge intensity is inadequate, is easy to collapse scarce or tearing；Meanwhile ligament width is consistent, with cutting-in
Deepen locally generate very big cutting force；The chip space designed thereon is flatter, and chip removal and volume bits performance are bad, is easy to scrape
Hurt machined surface, moreover, clast can also generate damage to blade；In addition, the fine grinding bottom surface of existing heavy duty roughing lathe tool exists
It is not reprocessed after coating, causes the fine grinding bottom surface depth of parallelism slightly worse, be easy to produce flutter in heavy duty processing.
Utility model content
For above-mentioned deficiency in the prior art, the utility model provides a kind of large-scale steel part heavy duty roughing lathe tool,
Existing lathe tool can effectively be solved and be easy tipping in processing, collapse scarce problem.
In order to solve the above technical problems, the technical solution adopted in the utility model are as follows:
A kind of large-scale steel part heavy duty roughing lathe tool, the turning cutter body including being in rectangle are provided；Before turning cutter body includes
Knife face, major flank and fine grinding bottom surface；
It is provided in the middle part of turning cutter body by its perforative through-hole；Be provided on turning cutter body it is several be located at rake face and through-hole it
Between, and the chip-breaker tangent with rake face；
Rake face and major flank intersection are provided with the main cutting edge with 10~30 ° of negative chamfered edges；The intersection of major flank
It is provided with the point of a knife being arc-shaped.
Preferably, cutting edge surface carries out blasting treatment, and with 15 ° of negative chamfered edge.
Preferably, point of a knife is located at turning cutter body quadrangle, and surface carries out blasting treatment, and with 15 ° of negative chamfered edge, radius
R is 2.4cm.
Preferably, major flank has 0 ° of relief angle.
Preferably, chip breaking rooved face carries out blasting treatment comprising the volume of several spaced sets considers concave point to be worth doing.
The utility model has the following beneficial effects:
1, it is provided with the negative chamfered edge with 10~30 ° at main cutting edge and the point of a knife being arc-shaped, considerably increased
The intensity of main cutting edge and point of a knife reduces lathe tool and occurs being broken, collapsing scarce problem in process, meanwhile, in conjunction with rear
Continuous blasting treatment eliminates cutting edge defect that may be present at main cutting edge and point of a knife so that lathe tool forms Waterfall type passivation,
Its intensity is promoted, lathe tool is further reduced and occurs being broken in process, collapses scarce problem.
2, chip-breaker and rake face are tangent, and there are multiple volumes to consider concave point to be worth doing, have in big cutting-in heavy duty processing good
Volume bits, chip breaking effect, reduce the friction between iron filings, then match with blasting treatment, further improve its volume bits, break
It considers effect to be worth doing, reduces cutting resistance, meanwhile, it can also effectively reduce influence of the chip breaking to lathe tool.
3, fine grinding bottom surface keeps soffit plane degree high, can allow lathe tool and edge bearing perfect combination, reduces flutter when processing
The blade breakages of initiation, large area collapse situations such as scarce.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present apparatus；
Fig. 2 is the structural schematic diagram of chip-breaker；
Fig. 3 is fine grinding bottom view.
Wherein, 1, point of a knife；2, major flank；3, main cutting edge；4, rake face；5, chip-breaker；6, through-hole；7, bottom surface is refined.
Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all are created using the utility model of the utility model design in the column of protection.
As shown in Figure 1, the large size steel part heavy duty roughing lathe tool, is in the turning cutter body of rectangle including section, and in vehicle
The centre of knife ontology is provided with the through-hole 6 for being fixed.
As shown in figures 1 and 3, which includes rake face 4, major flank 2 and fine grinding bottom surface 7, and fine grinding bottom surface 7 makes
Soffit plane degree is high, can allow lathe tool and edge bearing perfect combination, reduce the blade breakages that flutter when processing causes, big face
Product collapses situations such as scarce.
As shown in Figure 1, the intersection of rake face 4 and major flank 2 is provided with the main cutting edge of the negative chamfered edge with 10~30 °
3, the preferably angle of the negative chamfered edge is 15 °；The intensity that main cutting edge 3 can effectively be promoted, reduces it and collapses in process
The problem of sword；Meanwhile blasting treatment also is carried out to the cutting edge of main cutting edge 3, cutting edge defect is eliminated, Waterfall type passivation knot is formed
Structure further promotes the intensity of main cutting edge 3.
As shown in Figure 1, the intersection of major flank 2 is provided with the point of a knife 1 positioned at rectangle turning cutter body four corners, point of a knife 1 is in
Arc-shaped, arc-shaped radius R is 2.4cm, while it also has 10~30 ° of negative chamfered edge, the preferably angle of the negative chamfered edge
It is 15 °；Thus the structural strength that can guarantee point of a knife 1, avoids the problem that it tipping occurs in process；Meanwhile also to knife
Point 1 carries out blasting treatment, further to promote the intensity of point of a knife 1.
As depicted in figs. 1 and 2, on turning cutter body, several chip-breakers between rake face 4 and through-hole 6 are provided with
5, each chip-breaker 5 includes that several mutually independent volumes consider concave point to be worth doing, and 5 edge of chip-breaker and rake face 4 are tangent, that is, volume bits
Concave point edge and rake face 4 are tangent, meanwhile, blasting treatment also has been carried out to chip-breaker 5.
Chip-breaker 5 and rake face 4 are tangent, and there are multiple volumes to consider concave point to be worth doing, have in big cutting-in heavy duty processing good
Volume bits, chip breaking effect, reduce the friction between iron filings, then match with blasting treatment, further improve its volume bits, break
It considers effect to be worth doing, reduces cutting resistance, meanwhile, it can also effectively reduce influence of the chip breaking to lathe tool.
Specific embodiment has carried out detailed big foot and carefully has described, but should not be construed as the limit to the protection scope of this patent
It is fixed.In range described by claims, various modifications that those skilled in the art can make without creative work
Still belong to the protection scope of this patent with deformation.
