Description
technical field:
The utility model relates to a kind of main edging parts of edging lathe, and the right seat of the special edging of lathe is squeezed in a kind of piston rod cold breakdown specifically.
background technology:
Cold rolling & extruding process is surface chill polishing processing method, and it is that tumbling axle by high rigidity and smooth and surface of the work carry out edging, makes workpiece surface material produce Plastic Flow, thus forms the technological method for processing of new surface roughness.Workpiece after cold rolling & extruding process, top layer metallographic structure refinement also produces residual compressive stress, improves the case hardness of workpiece, bearing capacity, wear resistance, fatigue strength and corrosion resistance, and can obtain the superior work minute surface of surface property.
Current existing cold breakdown is squeezed lathe and is adopted branched tumbling axle and tapering turntable to combine, tumbling axle is driven to carry out roll extrusion to workpiece by rotating table, the similar taper roll bearing of working method, its design concept is based on endoporus minute surface edging head, because its working method exists drawback, the advantage that cold breakdown is squeezed does not give full play to, and product does not reach cold breakdown and squeezes optimum efficiency.Such as: the easy spot corrosion of tumbling axle working face, service life is low; Impulse stroke is by conicity regulation, and adjustable range is little, requires strict, increase the technology difficulty of last process to the outer diameter tolerance of workpiece before rolling & extruding process; Processing high-hardness workpiece, when pressure increases, tumbling axle axial force is fixed stop, easy stuck tumbling axle; The workpiece of processing different-diameter must change turntable and correlated parts, and lathe is without versatility.
Current piston rod cold-extruded is pressed with two kinds of processing modes: one drives piston rod to rotate by lathe, and piston rod initiatively.Cold extrusion frock is placed on machine tool guideway and travels longitudinally, three roller extrusion piston bars in frock, roller and plunger rod contacts area larger, extruding force is also just large, lathe is low for service life, and due to piston rod active, workpiece loading and unloading must be shut down during operation, production efficiency is low, adopt drag motion, the center that pivot and three rollers of piston rod form requires concentric, and very high to the requirement of guide rail linearity during lengthwise movement, piston rod easily produces flexural deformation, affects the linearity of piston rod; Another kind is that piston rod is placed in cold extrusion frock, and frock is primarily of needle roller, and cages for needle and pressure adjusting dish form.Cages for needle stirs needle roller by belt drive, drives piston rod rotate and do rectilinear motion, due to needle roller working surface contact adjustment plate, makes needle roller surface easily produce spot corrosion, affect piston rod surface roughness.It is adjust by the tapering of needle roller that external force applies, and the outside dimension of piston rod must in the margin of tolerance of regulation, ability by and process; Like this, the process of last process is just required very strict, increase technology difficulty; Each building block that lathe is squeezed in piston rod cold breakdown is extremely important.
summary of the invention:
The purpose of this utility model is to provide a kind of piston rod cold breakdown and squeezes the right seat of the special edging of lathe.
The utility model adopts following technical scheme to realize its goal of the invention: the right seat of the special edging of lathe is squeezed in a kind of piston rod cold breakdown, and it is made up of seat 2 under edging right seat upper cover 1, the right seat of edging; Edging right seat upper cover 1 to be arranged under the right seat of edging on seat 2.
The utility model, in order to realize the fixed installation of edging device, is provided with the right seat upper cover 1 of edging; And be provided with right seat upper cover installing hole 3, right convex roller bearing installing hole 4, upper right semicircle axis hole 5, upper right semicircle dead eye 6 thereon; Right seat upper cover installing hole 3 is located on angle, edging right seat upper cover 1 four, top; Right convex roller bearing installing hole 4, upper right semicircle axis hole 5, upper right semicircle dead eye 6 are located at edging right seat upper cover 1 bottom.
The utility model is installed in order to the support realizing edging device, is provided with seat 2 under the right seat of edging; And be provided with right seat upper cover fixing hole 7, bottom right semicircle axis hole 8, right edging seat installing hole 9, edging right seat fixing hole 10, bottom right semicircle dead eye 11, the recessed roller bearing bearing bore 12 of right active thereon; Right seat upper cover fixing hole 7, bottom right semicircle axis hole 8, right edging seat installing hole 9, bottom right semicircle dead eye 11 are located at seat 2 top under the right seat of edging; Edging right seat fixing hole 10, right active recessed roller bearing bearing bore 12 are located under the right seat of edging on the right side of seat 2, and edging right seat fixing hole 10, the recessed roller bearing bearing bore 12 of right active are through hole.
Owing to have employed above technical scheme, the utility model achieves its goal of the invention preferably, the cold breakdown of this piston rod is squeezed the right seat of the special edging of lathe and has been drawn the advantage that lathe is squeezed in external corresponding cold breakdown, in conjunction with design itself feature, break the design concept that lathe is squeezed in existing cold breakdown completely, its exclusive working method, the advantage that cold breakdown is squeezed is not fully exerted, and product quality reaches the optimum efficiency that cold breakdown is squeezed; Under the right seat of edging of design, seat mainly ensures the support installation of edging device and the reasonable installation of each parts of edging device; The cooperation that the right seat upper cover of edging of design achieves edging device is firmly installed, and ensure that normal mounting and the smooth working of each critical piece.
