Abstract
The utility model relates to a position guide block for stamping of a lead frame. The position guide block comprises a position guide block body. A position guide groove is arranged in the upper end surface of the position guide block body. Convex parts which are convex towards the internal part of the position guide groove are arranged at the upper parts of the two side surfaces of the position guide groove. The external surfaces of the convex parts are smooth surfaces. The position guide block is used for preventing the lead frame from being transversely deflected and being scratched during the stamping of the lead frame.
Description
Technical field
When the utility model relates to a kind of lead frame punching press with leading a piece.
Background technology
Lead frame is when punching press, and the common setting in the bottom of lead frame is led a piece and prevented that the lateral shift phenomenon from appearring in lead frame.The at present employed structure of leading a piece is as shown in Figure 2, and it comprises leads a block body 11, leads in a block body 11 upper surfaces and is provided with position guiding groove 12, and the two sides of position guiding groove 12 are inclined-plane 13.During punching press, the thick material position of lead frame 14 is arranged in the position guiding groove 12, realizes leading the position through the inclined-plane, both sides of position guiding groove 12.Its shortcoming is: because there is certain error unavoidably in the transverse width dimension of lead frame 14; When lead frame 14 punching presses; The thick material position of lead frame 14 can laterally be moved in position guiding groove 12; Because the two sides of position guiding groove 12 are inclined-plane 13, when laterally moving, the thick material position of lead frame 14 scratches mutually and impaired with inclined-plane 13.
The utility model content
The utility model technical problem to be solved is: when a kind of lead frame punching press that can the thick material of scratch lead frame position is provided with leading a piece.
For addressing the above problem; The technical scheme that the utility model adopts is: during the lead frame punching press with leading a piece; Comprise and lead a block body; Lead in the upper surface of a block body and be provided with position guiding groove, the top of said position guiding groove two sides is provided with the protuberance to the inner protrusion of position guiding groove, and the outer surface of protuberance is a round slip surface.
The beneficial effect of the utility model is: with leading a piece, it is simple in structure, easy to use during above-mentioned lead frame punching press.It is provided with the protuberance that outer surface is a round slip surface through the top in the two sides of position guiding groove, and when laterally moved in position guiding groove at the thick material position of lead frame, the side at the thick material position of lead frame only can contact with protuberance, thereby can be not impaired because of scratch.

Fig. 2 is the present employed structural representation of leading a piece described in the background technology;
Among Fig. 1: 1, lead a block body, 2, position guiding groove, 3, protuberance, 4, lead frame;
Among Fig. 2: 11, lead a block body, 12, position guiding groove, 13, the inclined-plane, 14, lead frame.
The specific embodiment
Do further to describe in detail with leading a piece during through specific embodiment below to the punching press of the utility model lead frame.
As shown in Figure 1, lead a block body 1 with leading a piece, comprising during the lead frame punching press, to lead in the upper surface of a block body 1 and be provided with position guiding groove 2, the top of position guiding groove 2 two sides is provided with the protuberances 3 to position guiding groove 2 inner protrusions, and the outer surface of protuberance 3 is a round slip surface.
The beneficial effect of the utility model is: with leading a piece, it is simple in structure, easy to use during above-mentioned lead frame punching press.It is provided with the protuberance 3 that outer surface is a round slip surface through the top in the two sides of position guiding groove 2; When laterally move in position guiding groove 2 at the thick material position of lead frame 4; The side at the thick material position of lead frame 4 only can contact with protuberance 3, thereby can be not impaired because of scratch.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
