Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further described.

See Fig. 1-Fig. 9, one molded can make two corresponding clamp supports 1 by the utility model, it comprises trimming G, raising C in technological process, bending L, shaping R, bending U, punching W, bending Y and cuts off the shape of Z2.1, this clamp support is as prior art, but the device structure making it is different.

The utility model comprises the cope match-plate pattern 21 in patrix 2, upper die plate 22, upper mould fixed plate 23 and stripper 25, and the lower bolster 31 in counterdie 3, counterdie fixed head 32, counterdie backing plate 33, material guide device 34, due to these parts and its concrete structure of part, connection and effect same as the prior art or equivalent, just do not describe one by one.

The utility model is also provided with pilot pin 41, buoyant pin assemblies 42, upper nitrogen spring assembly 431, lower nitrogen spring assembly 432, spring 44, push rod 45 and guide pillar guide pin bushing assembly 46, wherein: upper nitrogen spring assembly 431 is fixed with upper mould fixed plate 23, lower nitrogen spring assembly 432 is fixed with counterdie fixed head 32, and they are used for ensureing that product 10 i.e. tablet is ejected; Buoyant pin assemblies 42 is arranged on counterdie fixed head 32, is used for buoyance lift product 10 i.e. tablet, ensures feed level; Pilot pin 41 is fixed on stripper 25, is used for correcting feeding position; Spring 44 and push rod 45 are used for the product 10 i.e. tablet be enclosed within drift or punch down to release; Gap between guide pillar guide pin bushing assembly 46 correcting stripper 25 and each punch.

The utility model designs the structure of patrix 2 and counterdie 3 respectively according to the shape of clamp support 1.

Technological process of the present utility model comprises rushes the empty X-bending Y-shaping Z1-cut-out Z2 that stands of the bullport A-trimming B-raising C-punching D-trimming E-trimming F-trimming G-trimming H-empty I-of the station deburr or coin J-empty K-of the station bending L-empty M-of the station bending N-empty O-of the station bending P-empty Q-of the station empty S-of station of the shaping R-empty T-of the station bending U-empty V-of station punching W-.
