Background technology

Along with the competition of semiconductor electronic components and parts processing industry is growing more intense, market is to the appearance standard of electronic devices and components, and quality requirements is more and more stricter.And in process of production, the only a few components and parts cause the lead frame beading because of receiving influences such as other raw material, equipment or operate miss; Part pin root flattens, even the phenomenon that links together between pin, causes bad order or postorder test parameter bad and scrap; Traditional processing method is with sharp knife pin to be flattened part to slice off, and product can't be fixed in the process of sharp knife cutting, and sharp knife scratches the components and parts surface easily; Because of lead pin pitch is little, manual firmly inhomogeneous, slice off the beading part after; Appearance pin width differs, pin cuts off easily or squeeze the curved frame deformation that makes, and breaks off with one's hand directly at the two ends of lead-in wire if any a spot of beading and scraps, and in the process of breaking off with the fingers and thumb, can break the other end of product off with the fingers and thumb distortion; Cause the back operation can't ordinary production, cause and print no marking, train off, cut muscle and cut partially; Cut off etc., thus secondary more defective products.

The utility model content

The utility model provides a kind of beading prosthetic device, has solved in the past in the beading repair process, causes components and parts to be scratched easily, simultaneously, occurs easily also that pin width differs, pin cuts off easily or squeeze the curved problem that makes frame deformation.

The utility model is that the technical solution problem mainly realizes through following technical scheme: a kind of beading prosthetic device, comprise base plate, following baffle plate and upper guide post template, and said baffle plate down is arranged on the base plate; Said base plate is provided with the punching press guide pillar, and the upper guide post template is enclosed within on the punching press guide pillar, and following baffle plate is provided with lower cavity die and little guide pillar; Said lower cavity die is provided with down cutter and die groove, is socketed with cope match-plate pattern on the said little guide pillar, is fixed with upper slitter and convex template on the lower surface of cope match-plate pattern; Be fixed with limited block and stripper on the lower surface of said convex template; Said stripper is provided with the discharging cutter, and said upper guide post template is provided with gear and spring is hung arm, is fixed with the transmission arm of force on the said gear; The top that said spring is hung arm is fixed with return spring; The lower end of return spring is connected with tooth bar, and said tooth bar matches with gear on the upper guide post template, and tooth bar passes the upper guide post template and is connected with cope match-plate pattern through connecting rod.

Said lower cavity die is provided with pilot pin vertically.

The central shaft of said gear is through being bolted on the upper guide post template.

Said cope match-plate pattern is parallel to each other with following baffle plate.

Said punching press guide pillar is perpendicular to base plate, and little guide pillar is perpendicular to following baffle plate.

The utility model compared with prior art has the following advantages and beneficial effect: the utility model utilizes the lever principle driven gear to rotate through live the transmission arm of force with hand, and the rack drives patrix moves downwards then; Push down product,, directly partly cut away the beading on product pin both sides through upper slitter, upward knife edge and following cutter interlock; Its tangent plane is neat, and lead pin pitch is even, does not have distortion; Do not influence the quality of other orthodox materials on same the framework, and improved the quality of product, reduced scrappage; Overcome the industry manufacturing deficiency, improved production efficiency, further guaranteed quality.
