Abstract

The utility model discloses an automatic printing device of a progressive stamping die. The automatic printing device of the progressive stamping die comprises an upper die and a lower die, wherein the upper die comprises an upper template, a printing upper die base plate, a printing upper die and a printing upper punch; one end of the printing upper punch is fixedly connected to the printing upper die through a bolt; the lower die comprises a lower template, a printing lower die base plate, a printing lower die and a printing lower punch; the printing lower punch is embedded into the printing lower die and opposite to the printing upper punch. A chain plate can be printed at a time through cooperation of the printing upper punch and the printing lower punch, the working mode that the chain plate is stamped and then is printed in the prior art is changed, the working efficiency is improved, and production cost is saved; meanwhile, the problems that the printing position is inaccurate, the distance between the centers of two holes of the chain plate is affected, and then the chain length for assembling a chain is inaccurate are avoided.

Description

Stamping progressive die automatic band printing equipment

Technical field

The utility model belongs to Stamping Die Technology field, is specifically related to stamping progressive die automatic band printing equipment.

Background technology

Chain is generally comprised of parts such as carrier bar, chain pin, axle sleeves, for the punch forming of carrier bar, generally adopts stamping progressive die, but current existing stamping progressive die does not possess the function of printing to carrier bar.

It is by after carrier bar punch forming that existing carrier bar is printed, burr punching press being produced by planet rolling barrel is got rid of, then carrier bar is conspired to create to string by stringing device of chain plate, finally by punch press, prints one by one realization.The carrier bar which is carried out is printed, and is subject to it to pass through the impact of carrier bar profile secondary location, and its print position is not accurate enough, directly affects the outward appearance of chain.In addition, this kind of carrier bar printing type, owing to carrying out after carrier bar punching press, the effect that its punching press carrier bar two hole centre-to-centre spacing defections are printed and changing, directly affects the centre distance of carrier bar, and then the chain length precision of impact assembling chain.In addition, this kind of carrier bar printing type need could be realized through four operations, and production efficiency is lower, is difficult to meet the needs of producing in enormous quantities, meanwhile, because operation multi-step is loaded down with trivial details, also greatly increased the cost of manufacturing.

Summary of the invention

The above-mentioned defect existing in order to overcome prior art field, the purpose of this utility model is, a kind of stamping progressive die automatic band printing equipment is provided, solution is because the print position that caused by the impact of carrier bar profile secondary location is accurate not, after carrier bar punching press, print and affect carrier bar two hole centre distances, and then the problem of the chain length precision of impact assembling chain; Solution is because of the problem that the cumbersome production efficiency causing of operation multi-step is lower, manufacturing cost increases.

The stamping progressive die automatic band printing equipment that the utility model provides, it comprises upper die and lower die, described patrix comprises cope match-plate pattern, prints upper die plate, prints patrix and prints upper punch, described printing upper die plate is fixed on an end face of cope match-plate pattern, and being outwards equipped with printing patrix, described printing upper punch one end is bolted to connection is printing on patrix; Described counterdie comprises lower bolster, prints counterdie backing plate, prints counterdie and prints low punch, described printing counterdie backing plate is fixed on lower bolster one end face, and be outwards equipped with printing counterdie, and described printing low punch is embedded to be printed in counterdie, and patrix is relative with printing; Described cope match-plate pattern, printing upper die plate and printing patrix are bolted to connection, and described lower bolster, printing counterdie backing plate and printing counterdie are bolted to connection.

The stamping progressive die automatic band printing equipment that the utility model provides, its beneficial effect is: print upper punch and coordinating of low punch can once complete the print job to carrier bar with printing, change original working method that first punching press is printed again to carrier bar, increase work efficiency, save production cost; Also avoided print position inaccuracy, the problems such as chain length inaccuracy of the influenced and then assembling chain of carrier bar two hole centre distances simultaneously.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the utility model embodiment.

In figure, mark:

1. cope match-plate pattern; 2. print upper die plate; 3. print patrix; 4. print upper punch; 5. lower bolster; 6. print counterdie backing plate; 7. print counterdie; 8. print low punch; 9. workpiece.

The specific embodiment

With reference to the accompanying drawings, in conjunction with an embodiment, the stamping progressive die automatic band printing equipment that the utility model is provided is described in detail.

Embodiment

With reference to Fig. 1, the stamping progressive die automatic band printing equipment of the present embodiment, it comprises upper die and lower die, described patrix comprises cope match-plate pattern 1, prints upper die plate 2, prints patrix 3 and prints upper punch 4, described printing upper die plate 2 is fixed on an end face of cope match-plate pattern 1, and being outwards equipped with printing patrix 3, described printing upper punch 4 one end are bolted to connection is printing on patrix 3; Described counterdie comprises lower bolster 5, prints counterdie backing plate 6, prints counterdie 7 and prints low punch 8, described printing counterdie backing plate 6 is fixed on lower bolster 5 one end faces, and be outwards equipped with printing counterdie 7, and described printing low punch 8 is embedded to be printed in counterdie 7, and upper punch 4 is relative with printing; Described cope match-plate pattern 1, printing upper die plate 2 and printing patrix 3 are bolted to connection, and described lower bolster 5, printing counterdie backing plate 6 and printing counterdie 7 are bolted to connection.

Workpiece 9 to be punched is positioned on printing counterdie 7, descending by cope match-plate pattern 1, drive printing upper punch 4 descending, coordinate under the acting in conjunction of printing low punch 8 and print, under the effect of continuous punching, guaranteed the accurate of print position.
