Description
Technical field
The utility model discloses a kind of split pin forming machine, belong to and make the split pin apparatus field.
Background technology
At present, the circle split pin is standard component, commonplace on the market, but can use flat split pin in some production process, and flat split pin criteria of right and wrong part, all kinds of flat split pin that suitable for producing is used is difficult to buy, ordinary circumstance is that industrial enterprise make by hand entirely, time-consuming, the effort of this preparation method, efficient is low, and the flat cotter pin hole of making at that time just is fit to the needs of the condition of production at that time, and waiting until also needs other making when need next time again, can waste lot of materials, cause economic loss.
Subsequently, denomination of invention having occurred is flat split pin press, and application number is to be the patented technology scheme on October 30th, 2,008 200820139392 applyings date.This patented technology scheme is as follows: a kind of flat split pin press, comprise cylinder and table top, and it is characterized in that be connected with guide plate on the described table top, be equipped with connector fixing header board and back plate the guide plate upper end, the guide plate middle part is connected with guide pin bushing; Being provided with riser between described header board and the back plate, fixedlys connected with cylinder in the upper end of riser, is hinged with on this riser to press and cuts, and pressure is cut crossing fault mandrel is housed, and this mandrel other end is loaded in the guide pin bushing, and the mandrel afterbody is connected with connecting plate; Also be connected with extension spring on the described riser, the other end of this extension spring is fixed on the connecting plate; Also be connected with joint pin on the described connecting plate, torsion spring and ratchet are housed on this joint pin.The described press of above-mentioned patented technology scheme, though have the benefit of fixation workpiece,, structure is comparatively numerous and diverse, cause operation to increase, operation sequence increases, and, because, increased guide pin bushing, if wearing and tearing appear in guide pin bushing, the workpiece contraposition just is easy to skew occur, and percent defective improves certainly.And, defective anti-skidding, anti-avulsion that the split pin that this press makes does not possess.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of split pin forming machine, and it is easy that the split pin that this forming machine makes has a moulding, and make efficiency improves, and the split pin of manufacturing so also has anti-skidding, anti-avulsion, the benefit that pin joint is stable.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of split pin forming machine, comprise workbench, upper die and lower die, counterdie is arranged on the workbench relative with patrix, counterdie connects with workbench is movable, it is characterized in that: described patrix is provided with drift, counterdie is provided with for the groove of placing the bar shaped sheet-like workpiece, is provided with hollow-out parts with the drift correspondence position on the workbench.
The end that drift described in the utility model is relative with counterdie is provided with projection.
Also be provided with on the counterdie described in the utility model and described protruding corresponding groove.
The width coupling of the width of hollow-out parts described in the utility model and bar shaped sheet-like workpiece.
Operation principle of the present utility model and process are:
On the groove 4 with the placement of bar shaped sheet-like workpiece and counterdie 3, depress patrix 2,5 pairs of workpiece of the drift on the patrix 2 are implemented punching press, workpiece is under projection 8 actings in conjunction on groove 6 and the drift 5, and recessed in the middle of the workpiece, two upwarps slightly, at this moment, mention patrix 2, and, remove counterdie 3, said workpiece is placed on the hollow-out parts 7, depress patrix 2 again, obtain the kink inner ring projection is arranged, the split pin of closure tight close, in the side, the split pin that removes after the shaping gets final product.
Because the utility model has adopted technique scheme and operation principle, therefore, has following beneficial effect:
At first, counterdie is provided with for the groove of placing the bar shaped sheet-like workpiece, makes that workpiece namely can prevent from removing easily again on counterdie easily, and is convenient many than bolt or guide pin bushing;
Secondly, be provided with drift at patrix, made things convenient for component shaping;
The 3rd, workbench is provided with hollow-out parts, has made things convenient for drift in the process of pressing down, and the closing up of workpiece is to form the closure of split pin;
The 4th, the end that drift is relative with counterdie is provided with projection, is in order to make workpiece when bending for the first time, in the projection of kink formation to inner ring, has avoided the kink of split pin because of in using effectively, overexerts, and closure occurs, and passes pin-and-hole;
The 5th, counterdie is provided with and described protruding corresponding groove, further lays a good foundation to the projection of inner ring for kink forms;
The 6th, the width of the width of hollow-out parts and bar shaped sheet-like workpiece coupling, be for workpiece in the process that presses down, can not swing, guaranteed the closure tight close of split pin.
