Abstract
The utility model relates to an extruder, which is structurally characterized in that an adjusting nut is in threaded connection with a mandrel, an external circumferential boss of the adjusting nut is provided with a spring, the other end of the spring is contacted with an internal end face of a sleeve, and a bearing is arranged at one end of the adjusting nut and inside the sleeve. A limiter is further arranged on the external circumference of a bushing, the front end of the limiter is coaxially matched with the mandrel simultaneously, 2 to 5 evenly distributed grooves are arranged on the external circumference of the front end of the limiter, and rolling columns are arranged in the grooves and axially fixed through cylindrical pins. An end cover is arranged on the external circumference of the front end of the limiter and fixed through a screw II, the front end of the mandrel is in a round table shape and is contacted with the circumferential surfaces of the rolling columns, and the mandrel penetrates out from an inner hole of the end cover. A lock nut is further arranged on the rear end face of the adjusting nut and is in threaded connection with the mandrel. The extruder is simple in structure, the surface strengthening effects of steel part holes are good, and fatigue life and surface luminosity of the holes are greatly improved.
Description
Technical field
The utility model relates to a kind of squeezer, is used for the squeezer that the steel hole in piece part is strengthened on the surface of Ф 20～Ф 60mm.
Background technology
It is to cause surface significantly viscous deformation but the enhancement method that do not cut that extruding is strengthened.Hole extrusion hardening method, it can reach the purpose of the fatigue lifetime of improving the hole, thereby prolongs the work-ing life of part.Hole extruding is strengthened, and promptly adopts the high firmness compression tool of building ring greater than bore dia, through after the sufficient lubrication, pushes continuously, equably and through the hole, makes the hole wall metal produce viscous deformation and a kind of technological process that the hole is reinforced.In this course, can increase substantially metal parts hole limit fatigue lifetime and erosion-resisting ability, thereby prolong the time of crack initiation and diffusion, reach the purpose in the work-ing life that prolongs part.
Summary of the invention
The technical problem that the utility model will solve provides a kind of squeezer, and this squeezer is simple in structure, and the steel hole in piece part carries out the effective of surface strengthening, has improved the fatigue lifetime and the finish in hole greatly.
For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of squeezer, and its structure is: setting nut is connected with mandrel thread, and the excircle boss of setting nut is provided with spring; And place jointly in the sleeve, the other end of spring contacts with the telescopic inner face; At an end of setting nut and in sleeve, be provided with bearing, the other end of bearing is provided with lining, and lining is connected with the mandrel coaxial cooperation respectively with bearing; Excircle at lining also is provided with slicer, and slicer is connected with the telescopic inwall through the screw I, simultaneously the front end and the mandrel coaxial cooperation of slicer; On the fore end outer circumference of slicer, be provided with 2 ~ 5 equally distributed grooves, be provided with roller in the groove, roller is through the straight pin axial restraint; Fore end outer circumference at slicer is provided with end cap, and end cap is fixed through the screw II, and the front end of mandrel is a truncated conical shape; And contact with the periphery of roller, mandrel passes from the endoporus of end cap; Aft end face at setting nut also is provided with set nut, and set nut is connected with mandrel thread.
This squeezer adopts the structure of setting nut and set nut, can control moving radially of roller through moving axially of setting nut, with the aperture of control Strengthening Hole, and locks with set nut simultaneously; The front end of mandrel is a truncated conical shape, can guarantee that roller can move radially along the excircle of mandrel.With the rear end of mandrel with clamps on lathe, and adopt the processing mode of the swivel feeding of squeezer, can push reinforcement to multiple part material hole, simple in structure, do not receive the influence of profile, and easy to process.

Embodiment
As shown in Figure 1, a kind of squeezer, its structure is: setting nut 7 is threaded with mandrel 1, and the excircle boss of setting nut 7 is provided with spring 8, and places jointly in the sleeve 5, and the other end of spring 8 contacts with the inner face of sleeve 5; At an end of setting nut 7 and in sleeve 5, be provided with bearing 13, the other end of bearing 13 is provided with lining 6, and lining 6 is connected with mandrel 1 coaxial cooperation respectively with bearing 13; Excircle at lining 6 also is provided with slicer 4, and slicer 4 is connected with the inwall of sleeve 5 through screw I 12, simultaneously the front end and mandrel 1 coaxial cooperation of slicer 4; On the fore end outer circumference of slicer 4, be provided with 4 equally distributed grooves; Be provided with roller 3 in the groove, roller 3 is through straight pin 11 axial restraints, is provided with end cap 2 in the fore end outer circumference of slicer 4; End cap 2 is fixing through screw II 10; The front end of mandrel 1 is a truncated conical shape, and contacts with the periphery of roller 3, and mandrel 1 passes from the endoporus of end cap 2; Aft end face at setting nut 7 also is provided with set nut 9, and set nut 9 is threaded with mandrel 1.
During use, unclamp set nut 9, rotation adjusting nut 7; Because mandrel 1 and setting nut for being threaded, move radially so setting nut 7 can drive mandrel 1, the roller of while slicer 4 front ends promptly moves radially along the excircle of the round platform of mandrel front end; When size conforms predetermined diameter size; Be on the squeezer circumference relatively the roller diameter difference be not more than 0.01mm, then with set nut 9 lockings, the rear end of the squeezer of adjusting is installed on the lathe with unit clamp; The working parameter of adjustment lathe response; Roller 3 begins the swivel feeding motion under the drive of lathe,, promptly accomplish a hole extruding and strengthen all through being extruded hole in piece part until the roller length direction.
