Abstract
The utility model relates to a kind of turning roll extrusion composite knife bar of Precision Machining cylindrical outer surface, and it combines turning and two kinds of different techniques of roll extrusion, realizes one-pass and complete the object of two kinds of techniques.The utility model is on the basis of traditional round outer surface of column turning handle of a knife, install adjustable rolling device additional, in machining, also play the effect of rolling and processing, not only save process time, improve working (machining) efficiency, but also can reduce the surface roughness of processing column outer surface, improved its surface microhardness and fatigue life.
Description
Technical field
The utility model relates to a kind of turning roll extrusion composite knife bar of Precision Machining cylindrical outer surface, belongs to metal cutting machining tool technical field.
Background technology
The surface integrity (surface roughness, surface microhardness etc.) of cylindrical outer surface is the comprehensive characterization of its processing characteristics, and the quality of surface integrity is having a strong impact on serviceability and the life-span of cylindrical outer surface.Reducing the surface roughness of cylindrical outer surface and improving its microhardness is to weigh an important indicator of cutting circle outer surface of column crudy.
The intensifying method that improves now cylindrical outer surface crudy is mainly after machining completes, to carry out the secondary hardening techniques such as ultrasonic wave finishing hardening, shot peening strengthening and finish rolling hardening again.When secondary hardening, need to change cutter and adjust fixture and reorientate, having reduced working (machining) efficiency, having increased production cost.
Summary of the invention
The utility model is in order to solve in cylindrical outer surface machining, and secondary hardening process causes the problem that working (machining) efficiency is low, in conjunction with cutting technology and roll extrusion technology, has proposed a kind of turning roll extrusion composite knife bar technology that can Precision Machining cylindrical outer surface.The utility model organically combines machining and rolling and processing, realizes cutting and rolling and processing in one-pass process simultaneously, can improve suface processing quality, saves process time, increases economic benefit.
Main technical schemes of the present utility model is: a kind of turning roll extrusion composite knife bar of Precision Machining cylindrical outer surface is mainly installed matrix by turning insert, turning insert hold-down bolt, turning knife bar matrix, milled head, milled head and matrix adjustment bolt is installed and forms.Described turning insert is fixed on the front end of turning knife bar matrix by turning insert hold-down bolt, and completes the main cutting removal process of material.Milled head is installed matrix by matched in clearance and milled head and is connected, and milled head is installed matrix and is connected with turning knife bar matrix by matrix adjustment bolt is installed.Milled head in direction of feed, be positioned at turning insert after, follow turning knife bar matrix moving linearly, realize roll extrusion, the strengthening of cylindrical outer surface.The amount of overhanging that the roll extrusion deep exploitation amesdial of finish rolling hardening is adjusted milled head installation matrix realizes different roll extrusion degree of depth rolling and processing cylindrical outer surfaces.
The present invention combines turning processing and rolling and processing by composite knife bar technology, one-pass just can complete the Precision Machining of cylindrical outer surface, save the clamping time of rolling tools, improve working (machining) efficiency, reduce the surface roughness of workpiece cylindrical outer surface, apply surperficial compressive pre-stress, improved surface microhardness, extended fatigue life.
Brief description of the drawings
The utility model turning roll extrusion composite knife bar structural representation.
Detailed description of the invention
Below with reference to accompanying drawing, structure of the present invention and operation principle are elaborated.
As shown in the figure, the utility model provides a kind of turning roll extrusion composite knife bar of Precision Machining cylindrical outer surface, by turning technology and roll extrusion technology are combined, existing turning knife bar is improved, add adjustable milled head, realized the Precision Machining of cylindrical outer surface.
The roll extrusion function of the turning roll extrusion composite knife bar that the utility model is mentioned is mainly that the cylindrical outer surface after turning is machined is processed.As shown in the figure, turning insert 1 is fixed on the front end of turning knife bar matrix 3 by turning insert hold-down bolt 2, by moving linearly, coordinates the main workpiece material removal work of having rotatablely moved of cylindrical workpiece simultaneously.Milled head 4 is arranged on turning insert 1 milled head installation matrix 5 below by matrix adjustment bolt 6 is installed along the direction of feed of composite knife bar.The conical surface of 5 ° ~ 20 ° is left in the front portion of milled head 4, and the roll extrusion power that milled head 4 just can produce by the front end conical surface in the time of rolling and processing like this compresses milled head 4, in case milled head 4 drops in process, causes operator's personal injury and workpiece to lose efficacy.Actually add man-hour, the cutting parameter of turning processing is realized by the program of adjusting Digit Control Machine Tool; The machined parameters roll extrusion degree of depth of rolling and processing is installed matrix adjustment bolt 6 by amesdial adjustment and is realized.
In sum, the utility model proposes a kind of turning roll extrusion composite knife bar of Precision Machining cylindrical outer surface, turning processing and rolling and processing are organically combined, realized one-pass, secondary operations, has improved working (machining) efficiency and crudy.After the processing of turning roll extrusion combined precision, can reduce the cylindrical outer surface surface roughness of different materials, improve surface microhardness, improve fatigue life, can produce significant economic benefit.
More than implementing concrete case is only explanation technical method of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain.
