Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Change as seen in figures 3-5 and amendment.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
As seen in figures 3-5, single-blade chip breaking extended type reamer 100 of the present utility model comprises: cutter hub 10, be formed at the cutter head 20 of cutter hub 10 one end and be formed at the handle of a knife 30 of described cutter hub 10 other end.Wherein, cutter head 20 is for cutting, and cutter hub 10 plays guide effect, thus cutting is born by the different position of two on reamer from guiding by single-blade chip breaking extended type reamer of the present utility model respectively.
Described cutter head 20 has the first blade 21 and the second blade 22.Wherein, described first blade 21 and the second blade 22 form Double-blade structure, the radial load of the two and the guiding of having made a concerted effort of tangential force, support and squeezing action.Particularly, described first blade 21 is positioned at one end of described cutter head 20, and its length is 1mm ~ 3mm, and oblique angle A is 25 ° ~ 45 °.Wherein, oblique angle refers to the angle between the tangential direction of the first blade 21 and cutter hub 10 radial direction.Second blade 22 plays the effect of cutting most of surplus, and its length is 0.5mm ~ 2mm, and tool cutting edge angle is 3 ° ~ 15 °, and wherein, tool cutting edge angle refers to the angle between the tangential direction of the second blade 22 and the axial direction of cutter hub 10.In addition, described cutter head 20 has rake face, this rake face offers chip-breaker 23, and this chip-breaker 23 makes working angles more steady, and then reaches good chip breaking effect.
Described cutter hub 10 forms the targeting part of reamer of the present utility model, and preferably, cutter hub 10 is cylindrical, and the ratio of its length and diameter is: 8-15:1.Thus cutter hub 10 is longer, so, both can improve the rigidity of cutter head cutting tip, and in whole process, make the cutting of cutter head be support reliably at one and guiding basis is carried out, to ensure machining accuracy.In addition, described cutter hub 10 also offers chip pocket 11, it makes blade have independently chip space, and described chip pocket 11 one end is connected with the chip-breaker 23 on described rake face.Further, described chip pocket 11 is extended along the length direction of described cutter hub 10.
Described handle of a knife 30 forms the installation end of the utility model reamer.
Contrast below in conjunction with the stock-removing efficiency of test data to reamer of the present utility model and existing reamer.Take non-ferrous metal such as, as processing object, aluminium alloy.Result is as shown in table 1 below:
| Cutting situation | Reamer of the present utility model | Existing reamer |
| Processing mode | 2 layers of processing, cutting depth 90mm | 3 layers of processing, cutting depth 90mm |
| Stock-removing efficiency | 500％ | 100％ |
As can be seen here, compared with existing reamer, reamer of the present utility model has higher machining efficiency.
To sum up, single-blade chip breaking extended type reamer of the present utility model is easy to use, flexible operation, and it has completely independently chip space.And ream is combined with extruding, not only make working angles more steady, and can be good at chip breaking, improve precision and the rigidity of processing.
In addition, compared with existing reamer, adopt single-blade chip breaking extended type reamer of the present utility model to allow to retain more reaming allowance, therefore, can save and slightly cut with scissors operation, increase work efficiency.And, when allowance little and even time, reamer of the present utility model, while carrying out finish reaming, can provide enough large cutting force, and can select the larger amount of feeding.Cutting speed 60 ~ 90% can be improved, and monodentate chip breaking ability can be increased, improve stock-removing efficiency 3-5 doubly.
Further, reamer of the present utility model, weight reduction on the whole of leading, makes cutting force distribute more reasonable, is issued to the object strengthening cutter rigidity in the condition not increasing tool weight.Be widely used in high-speed and high-efficiency ream, deep hole precision cutting tool, significantly, application prospect is better for economic benefit and social effect.
