Description
Technical field
The present invention relates to a kind of machining accessory, particularly a kind of roll extrusion cutter head.
Background technology
How the processing industry highly competitive of present parts, improve crudy, improves level of processing, saves processing cost, become extremely urgent thing.
Through consulting related data, use car, boring, draw, mill, vertical milling, scrape, the processing method such as roll extrusion can meet the requirements of roughness, but in conjunction with the feature of existing process equipment and part self, can only process at numerical control vertical lathe for golden wind turning cylinder, stator main shaft, so can only select in car, roll extrusion; For Siemens, auspicious energy bearing block, can only carry out Boring at numerical control borer.
Rolling and processing is that high rigidity and smooth roller are contacted with metal surface roll extrusion, makes its superficial layer occur to improve after the plastic deformation of local trace one of plastic working method of surface roughness.The workpiece of rolling and processing not only surface roughness moment just can reach Ry0.1-0.8 μ m, and fatigue strength has also increased by 30% when after machined surface sclerosis, its wearability is improved, has advantages of in machining and cannot obtain.
But existing rolling tools are analyzed, are found now to have following shortcoming with rolling depression cutter:
1) processing method aspect: owing to having human error in clamping rolling depression cutter, when tool setting, likely there is the situation that rolling wheel is vertical not with rolling surface, thereby cause rolling surface unbalance stress in rolling process, make roll extrusion get off roughness less than very stable, sometimes cannot reach the requirement of drawing.
2) processing parts aspect: piece surface can say that surface roughness can reach a higher level under last cutter finish turning processing, but also cannot avoid existing flaw, may also exist some because the finished surface hardness that part material points hardness problem causes is inconsistent in surface, make also cannot obtain good roughness with regard to this under roll extrusion.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the invention discloses the roll extrusion cutter head that a kind of Adjustiny device error automatically and energy processing part case hardness differ.
Technical scheme: the invention discloses a kind of roll extrusion cutter head, comprise, cutter shell, is arranged on the blade in cutter shell, and cutter shell is stretched out in blade one end, and port is fixed roll extrusion cutter head by clamping bolt, and the other end is provided with adjusting bolt, is provided with spring between adjusting bolt and blade.
Wherein, described roll extrusion cutter head comprises mandrel, and described mandrel upper end is connected with blade by clamping bolt, and lower end is provided with roller, is also provided with self-aligning bearing between mandrel and roller, and mandrel outside cover has spacer shell; When the roller that described self-aligning bearing makes uses, differ and automatically adjust for surface of the work hardness, improve machining accuracy.
Wherein, the external diameter of blade is identical with the internal diameter of cutter shell, ensures blade non-loosening in cutter shell, strengthens machining accuracy.
Wherein, described blade and spring are coaxial, prevent active force skew, ensure that automatic tool preset is accurate.
The shortcoming existing for existing rolling tools, we must overcome these drawbacks by the special rolling tools of design, so we have embodied flexible design requirement by the rolling tools of design: we have designed spring in rolling tools the inside, on rolling wheel, assemble self-aligning bearing, this different design update just makes tool setting error and surface of the work hardness differ and can overcome, make the contact finished surface that roller in rolling process can be fully effectively, complete rolling process.
Beneficial effect: roll extrusion cutter head disclosed by the invention, simple in structure, can effectively overcome tool setting error and surface of the work hardness differs, improve machining accuracy.
Brief description of the drawings
Accompanying drawing 1 is rolling depression cutter header structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further explained.
The invention discloses a kind of roll extrusion cutter head, comprise, cutter shell 1, is arranged on the blade 2 in cutter shell 1, and cutter shell 1 is stretched out in blade 2 one end, and port is by the fixing roll extrusion cutter head 4 of clamping bolt 3, and the other end is provided with adjusting bolt 5, between adjusting bolt 5 and blade 2, is provided with spring 6.
Wherein, described roll extrusion cutter head 4 comprises mandrel 7, and described mandrel 7 upper ends are connected with blade 2 by clamping bolt 5, and lower end is provided with roller 8, between mandrel 7 and roller 8, is also provided with self-aligning bearing 9, and mandrel 7 outside covers have spacer shell 10; When the roller that described self-aligning bearing makes uses, differ and automatically adjust for surface of the work hardness, improve machining accuracy.
Wherein, the external diameter of blade is identical with the internal diameter of cutter shell, ensures blade non-loosening in cutter shell, strengthens machining accuracy.
Wherein, described blade and spring are coaxial, prevent active force skew, ensure that automatic tool preset is accurate.
The shortcoming existing for existing rolling tools, we must overcome these drawbacks by the special rolling tools of design, so we have embodied flexible design requirement by the rolling tools of design: we have designed spring in rolling tools the inside, on rolling wheel, assemble self-aligning bearing, this different design update just makes tool setting error and surface of the work hardness differ and can overcome, make the contact finished surface that roller in rolling process can be fully effectively, complete rolling process.
Roll extrusion cutter head disclosed by the invention, simple in structure, can effectively overcome tool setting error and surface of the work hardness differs, improve machining accuracy.
The invention provides a kind of thinking and method of roll extrusion cutter head; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
