Abstract
The utility model discloses a kind of piston rod cold breakdown and squeeze holder after lathe supporting feed mechanism, it forms rear holder by steel are refining, and is provided with rear holder slide bar semicircle folder hole and rear holder fixing hole thereon; After lathe supporting feed mechanism is squeezed in the cold breakdown of this piston rod, holder has 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; The holder arranged is for fixedly mounting slide bar specially, and what it on, several installing holes of setting were convenient to holder facilitates I&M.
Description
technical field:
The utility model relates to a kind of pay-off parts of lathe, and holder after lathe supporting feed mechanism 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 holder after lathe supporting feed mechanism.
The utility model adopts following technical scheme to realize its goal of the invention: holder after lathe supporting feed mechanism is squeezed in a kind of piston rod cold breakdown, and it forms rear holder 1 by steel are refining; And be provided with rear holder slide bar semicircle folder hole 2 and rear holder fixing hole 3 thereon; Rear holder slide bar semicircle folder hole 2 is located at rear holder about 1 two ends; Rear holder fixing hole 3 is located at rear holder 1 center, and is through hole.
Owing to have employed above technical scheme, the utility model achieves its goal of the invention preferably, after lathe supporting feed mechanism is squeezed in the cold breakdown of this piston rod, holder has 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; The holder arranged is for fixedly mounting slide bar specially, and what it on, several installing holes of setting were convenient to holder facilitates I&M.
accompanying drawing illustrates:
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Description of reference numerals is shown in description last page form.
detailed description of the invention:
Below in conjunction with accompanying drawing, utility model content is described further:
embodiment 1:
From summary of the invention, holder after lathe supporting feed mechanism is squeezed in a kind of piston rod cold breakdown, and it forms rear holder 1 by steel are refining; And be provided with rear holder slide bar semicircle folder hole 2 and rear holder fixing hole 3 thereon; Rear holder slide bar semicircle folder hole 2 is located at rear holder about 1 two ends; Rear holder fixing hole 3 is located at rear holder 1 center, and is through hole.
Rear holder 1 described in the utility model refers to: the building block of holder; Which is provided with rear holder slide bar semicircle folder hole 2, rear holder fixing hole 3; Its structure as shown in Figure 1.
Rear holder slide bar semicircle folder hole 2 described in the utility model refers to: be located at the semicircle folder hole on rear holder 1; Its effect is convenient to install slide bar; Its design attitude is as marked shown in 2 in accompanying drawing 1.
Rear holder fixing hole 3 described in the utility model refers to: be located at the fixing hole on rear holder 1; Its effect is the installation being convenient to holder; Its design attitude is as marked shown in 3 in accompanying drawing 1.
