In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Example one

Please refer to fig. 1 and 3, the utility model relates to a copper bar die R angle towards device, including upper die base 1, connect in fillet terrace die 2 of 1 lower surfaces of upper die base to and fillet die supporting 3, the fixed surface is connected with towards hole post 4 under 1 of upper die base, and fillet die supporting 3 sets up the nib 301 that corresponds with towards hole post 4 position.

As shown in fig. 2, the length of post 4 punches a hole is greater than fillet terrace die 2's height, the lower terminal surface position of post 4 punches a hole promptly is less than fillet terrace die 2's lower surface, when making upper die base 1 move down, post 4 punches a hole earlier with the copper bar contact, earlier through post 4 and the cooperation of nib 301 punch a hole promptly, the realization punches a hole to the copper bar, rethread fillet terrace die 2 carries out fillet processing with the cooperation of fillet die-supporting 3 to the copper bar, thereby the realization punches a hole and the die-cut synchronous processing in fillet to the copper bar, the production processes of copper bar has been reduced, the effectual production efficiency who improves copper bar processing.

Simultaneously, earlier through post 4 and the cooperation of nib 301 of punching a hole, realize punching a hole to the copper bar, rethread fillet terrace die 2 carries out the fillet processing with the cooperation of fillet die 3 to the copper bar to the utilization is punched a hole the post 4 and is realized carrying out spacing fixed effect to the copper bar, is favorable to improving the stability of copper bar when the fillet is die-cut, makes the machining precision of copper bar obtain improving.

Wherein, the cross sectional shape of the lower terminal surface of post 4 that punches a hole is U type structure, or is V type structure, or the terminal surface of post 4 that punches a hole can be the curved surface structure of indent, is favorable to improving the punching effect of post 4 that punches a hole, and can avoid the condition emergence of piece etc. easy adhesion terminal surface under post 4 punches a hole.

Meanwhile, as shown in fig. 4 and 5, the lower surface of the fillet supporting die 3 is provided with a discharge hole 302 corresponding to the position of the die hole 301, and the inner diameter of the discharge hole 302 is larger than that of the die hole 301, so that copper scrap generated by punching can be discharged out of the die hole 301 more smoothly.

Example two

On the basis of the first embodiment, the punching device further comprises a pressing block 5 provided with a through hole 501 matched with the punching column 4; the upper surface of the pressing block 5 is fixedly connected with a guide rod 502, and the guide rod 502 is movably connected with the upper die base 1 in a penetrating manner, so that the pressing block 5 can slide along the axial direction of the punching column 4, the guide rod 502 and the upper die base 1 can be limited by a clamp spring, and the pressing block 5 is prevented from slipping on the punching column 4.

The guide rod 502 and/or the punching column 4 are/is sleeved with a spring 503, as shown in fig. 2 for example, the spring 503 is sleeved on the punching column 4, and the lower end of the spring 503 abuts against the pressing block 5.

The lower surface position of the pressing block 5 is lower than the lower surface of the fillet male die 2 and is used for pressing down and fixing the copper bar through the pressing block 5. And, before punching a hole, the lower terminal surface of post 4 that punches a hole is located perforating hole 501 for when upper die base 1 moves down, before punching a hole, briquetting 5 contacts the copper bar earlier, thereby realizes pushing down fixedly to the copper bar, avoids the copper bar to take place the condition emergence of offset, thereby can prevent that the copper bar from taking place to jump the condition of material, is favorable to improving holistic machining precision.

The lower terminal surface of post 4 that punches a hole is located perforating hole 501 for the back of punching a hole, when upper die base 1 moved up, post 4 that punches a hole when retracting perforating hole 501, usable briquetting 5 cleared up post 4 lower extreme that punches a hole, if the copper scraps waste material that punches a hole and produce bonds when post 4 lower extreme that punches a hole, post 4 that punches a hole copper scraps waste material when retracting perforating hole 501 in then is blockked to break away from post 4 that punches a hole, avoids punching a hole next time and causes the influence.

EXAMPLE III

On the basis of the second embodiment, the pressing block 5 is provided with a convex block matched with the round corner surface of the round corner convex die 2 on one side, and when the round corner convex die 2 is moved upwards, the convex block is cleaned, so that the situation that foreign matters such as copper scraps are adhered to the punching blade or the side surface of the round corner convex die 2 is avoided, and the round corner processing quality is ensured.

Meanwhile, the rubber layer is coated on the lower surface of the pressing block 5 in an attached mode, the rubber layer is in contact with the copper bar, the pressing block 5 can be prevented from pressing the copper bar or generating indentation, and therefore the product quality of the copper bar is guaranteed.
