Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b):
as shown in fig. 1, a positioning structure of a chain plate punching device comprises a positioning bracket 17, wherein the positioning bracket 17 is U-shaped, and two legs of the positioning bracket 17 are fixed on the side surface of an upper die plate 10. A through hole is arranged on the transverse connecting rod of the positioning bracket 17, a mandril 18 penetrates through the through hole, a compression spring 19 is sleeved on the mandril 18, one end of the mandril 18 is fixed on the transverse connecting rod of the positioning bracket 17, and the other end of the mandril 18 is propped on a positioning piece 22. One end of the pressing spring 19 abuts against the positioning bracket 17, the other end of the pressing spring 19 abuts against the pressing plate 20, the pressing plate 20 is installed on the side surface of the upper die plate 10, and the pressing spring 19 is always in a compressed state. The positioning piece 22 is positioned in the upper template 10, and one side of the positioning piece 22 is provided with an arc-shaped positioning surface, and the arc-shaped positioning surface has the same shape as the side arc line of the chain plate 13.
