Description
Technical field
The present invention relates to ball cold header, relate in particular to the master slider parts in the ball cold header.
Background technology
Ball cold header is the special purpose machine tool with header system punching out steel ball blanks, and it comprises charging, blank, cold-heading and the motion such as ejects.Wherein, cold-heading and eject all and to drive the master slider moving linearly by toggle and realize, fixed-type die cavity in the cold upsetting forming die is fixed on the lathe bed side of master slider slippage inner chamber, mobile shaping mold cavity is fixed on the master slider, decide the right opposite that shaping mold cavity is positioned at mobile shaping mold cavity, master slider is realized moving back and forth by toggle, thereby constantly upsetting pressure goes out steel ball blanks.Master slider is arranged on by the lower railway plate, left track plates, right track plates and top platen form in the specific sliding rail, in steel ball punching out process, because master slider provides power by toggle, left track plates and right track plates only play the guiding role, only be subjected to the friction effect, lower railway plate and top platen are then born the effect of the torsional forces of direction checker, therefore in actual use, the service life of left track plates and right track plates is longer, and the service life of lower railway plate and top platen is shorter, when the wear extent of track plates and top platen reaches capacity instantly, master slider will be excessive in the movement clearance of above-below direction, cause the punching out steel ball mismatch defective to occur, directly have influence on the quality of steel ball, in ball cold header, the lower railway plate is positioned at the below of master slider, and be fixed on the lower support surface lathe bed of rail groove, when the wearing and tearing of the lower surface of master slider pair of friction components are overproof, master slider must move down, in order to prevent mismatch, can only carry out height to fixed-type die cavity by trimming bolt and regulate, to guarantee and the accurate matched moulds of mobile shaping mold cavity.Top platen is positioned at the top of master slider, and be fixed on the lathe bed upper surface, rail groove side, when wearing and tearing when overproof in the lower surface of top platen, can only dismantle it again that grinding installs again, eliminate between master slider upper surface and the top platen producing the gap with this, so not only workload is large, maintenance downtime is long, directly have influence on the utilization rate of equipment, and eliminate fit clearance by integral body again grinding method, accelerated the shortening in top platen service life; When the upper surface of master slider wear extent is overproof, then can't eliminates between master slider upper surface and the top platen and produce fit clearance.Run into defective like this, according to the equipment operating manual requirement, this equipment must be scrapped by complete machine, or changes the master slider parts, and maintenance cost is high, and this is the critical defect that the master slider parts exist in the ball cold header.
Summary of the invention
In order effectively to overcome the defects that the master slider parts exist in the ball cold header, the purpose of this invention is to provide a kind of ball cold header master slider gap adjusting mechanism, it can regulate the gap that produces between master slider and the top platen easily, can simplify the gap adjustment mode, shorten maintenance time, reduce maintenance cost, the utilization rate of raising equipment, can prolong again the service life of top platen and master slider, no matter be the wearing and tearing of top platen lower surface, or the wearing and tearing of the upper surface of master slider cause that fit clearance is overproof can both eliminate easily between the two, can overcome technically the technical barrier that the wearing and tearing of master slider upper surface can not be repaired use after overproof.
