Detailed Description
The embodiments of the present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which the embodiments of the present utility model are shown by way of illustration only, and the utility model is not limited to the embodiments of the present utility model, but other embodiments of the present utility model will be apparent to those skilled in the art without making any inventive effort.
The flat link blank 3 is provided with a blank 5 at the periphery and inside of the blank as shown in fig. 2 before trimming and punching, the object of the utility model is to trim and punch the flat link blank 3, to punch two through holes inside the flat link blank 3 and to cut off the excess blank 5 around the contour.
Referring to fig. 1 to 4, a trimming and punching composite die special for a flat link comprises: the die comprises a die holder 1, wherein a die cavity 14 is formed in the die holder 1; the top of the die cavity 14 is opened, the two sides of the opening are provided with trimming concave dies 11, and the trimming concave dies 11 are provided with openings matched with the shapes of the flat chain link blanks 3; two punching female dies 12 are arranged in the film cavity; a spring 13 is arranged between the two punching female dies 12, and the bottom of the spring 13 is fixedly connected to the inner wall of a die cavity 14; the opening of the die cavity 14 is provided with a bottom support 2, the bottom support 2 is connected with the top of the spring 13, the bottom support 2 is provided with a through hole matched with the punching die 12 in shape, and when the bottom support 2 is pressed down, the punching die 12 penetrates through the through hole; the upper part of the collet 2 is provided with a flat chain link, and a punch 4 is arranged above the flat chain link.
The contact part of the trimming die 11 and the flat chain link blank 3 is provided with an arc cutting die, the cross section of the arc cutting die is preferably trapezoidal, the opening shape of the arc cutting die is set to be the peripheral shape of the flat chain link blank 3, the waste blank 5 is cut off from the flat chain link blank 3 during cutting, and the arc cutting die ensures trimming precision.
The punching die 12 is preferably of cylindrical configuration so that a relatively smooth round hole is punched during punching.
