Summary of the invention
To attach the chain outer plate precision of plate carrier chain not high in order to solve processing belt in the prior art; The technical problem that process equipment complex structure manufacturing cost is high; The utility model provides a kind of simple and reasonable outer plate processing unit (plant), and the converted products precision is high, chain operates steadily reliably after assembling.
The technical scheme of the utility model is: a kind of outer plate processing unit (plant), comprise cope match-plate pattern, die, die shoe and guiding mechanism, and the upper fixed of cope match-plate pattern has the flange die shank; Cope match-plate pattern is provided with push rod, and push rod inserts in the flange die shank, and an end of push rod is connected with punch; Punch embeds die; The upper fixed of die shoe has concavo-convex mould fixed head, and concavo-convex mould fixed head is provided with concavo-convex mould, and concavo-convex mould is corresponding with the punch position; Concavo-convex mould fixed head is provided with buffer gear, and cope match-plate pattern is connected through guiding mechanism with die shoe.The punching press outer plate, blanking, moulding are once accomplished, and enhance productivity, and save production cost.
As preferably, buffer gear comprises cushion pad and backing pin, and cushion pad and concavo-convex mould fixed head upper surface are fixed, and backing pin is cylindrical, and one of backing pin is inserted cushion pad, and the backing pin outer wall that inserts cushion pad is with spring.There is resilience after outer plate blanking, the punch forming.Processing unit (plant) is punching press once more, and buffer gear is shared the part surge, guarantees the screen resilience after multiple stamping press is just in time eliminated the outer plate moulding, and is simple and reasonable.
As preferably, guiding mechanism comprises guide pillars and bushes, and guide pillar is connected with die shoe, and guide pin bushing is connected with cope match-plate pattern, and guide pin bushing is provided with no gap linear bearing, and guide pin bushing is through no gap linear bearing and guide pillar socket.Use no gap linear bearing, reduced the gap of guiding mechanism, guaranteed punching precision.The about cost of guide pin bushing wearing and tearing trifle.
Compared with prior art, the utility model beneficial effect is: outer plate blanking, punch forming are once accomplished, and enhance productivity, and save production cost.After the outer plate punch forming once more punching press eliminate screen resilience and guarantee machining accuracy, it is reliable to operate steadily after the chain assembling.
