Fig. 1 is a schematic structural view of a lock plate, which has an irregular contour and an inner hole. The lock plate is a key part of an automobile door lock, the product quality requirement is high, the section bright band is more than 90%, the sag is 15% lower than the material thickness, and the flatness needs to reach 0.1 mm. The largest cross-sectional dimension of the lock plate is 200mm long and 80mm wide.
As shown in fig. 2, the locking plate fine blanking die includes an upper die assembly 20 and a lower die assembly 21. For blanking the locking plate shown in fig. 1.
The upper die assembly 20 comprises an upper die plate 1, an upper backing plate 2, an upper clamping plate 3 and an intermediate plate 7 which are arranged in sequence from top to bottom. Wherein, the upper template 1, the upper backing plate 2 and the upper clamping plate 3 are fixed, and are matched with each other for installing components such as a punching mandril 6, etc., the upper backing plate 2 is used for replacing when a punch-die 5 (see the following) is worn and repaired, and the thicker upper backing plate 2 is replaced to ensure that the punch-die 5 is adapted to the lower die assembly 21.
The intermediate plate 7 is movably arranged with the upper template 1 through a guide post 18 and a guide sleeve 19. The intermediate plate 7 and the upper die plate 1 move relatively more firmly under the guidance of the guide posts 18 and the guide sleeves 19.
A stop plate 4 is further arranged in the middle plate 7, and the stop plate 4 is positioned below the upper clamping plate 3 and used for stopping the stroke of the upper clamping plate 3 (together with the upper die plate 1 and the upper backing plate 2) so as to control the blanking stroke.
A ring gear plate 8 is fixed below the middle plate 7, and the lower surface of the ring gear plate 8 is provided with a linear extending convex strip (not shown) which is correspondingly pressed on the periphery adjacent to the outer contour of the lock plate so as to limit the transverse movement of the lock plate workpiece during blanking.
The upper die assembly 20 is also provided with a punch-die 5, and the punch-die 5 is fixed on the upper backing plate 2 and the upper die plate 1 through screws and extends into the stop plate 4 and the gear ring plate 8.

Compared with the design of the hanging platform structure in other embodiments, the method for controlling the stroke of the ejector 15 has low cost and long service life of the die.
The punching male die 13 and the inner holes in the lock plate are equal in number and same in shape. The punching male die 13 is arranged corresponding to the punching mandril 6 in the male and female dies 5 so as to punch an inner hole in the lock plate. The punching male die 13 punches upwards, the punching ejector rod 6 abuts against the burr surface (upper surface) of the lock plate to provide reverse acting force to better match with the punching male die 13 for punching, and the punching ejector rod 6 moves downwards to eject the inner hole waste material after the punching male die 13 punches.
The punching male die 13 is fixed on the lower cushion plate 10 through a hanging table, so that the installation and the disassembly are convenient.
The lower cushion plate 10 is internally provided with a lower cushion block 14, the lower cushion block 14 is positioned below the female die 16, and the lower cushion block 14 is used for adjusting the horizontal height of the female die plate 9 during initial installation or subsequent wear and repair of the die.
The lower template 17 and the upper template 1 are connected through a guide post 18 and a guide sleeve 19 for good guidance.
The lock plate is formed by fine punching, the section bright band reaches more than 90%, the sag is lower than the material thickness by 15%, the flatness reaches 0.1mm, the subsequent procedures of correction and leveling are not needed, the product is formed once to meet the technical requirements, the quality is stable, and the cost is low.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
