The invention relates to the technical field of blanking progressive dies, in particular to a novel double-discharging-plate structure progressive stamping die.
Background
The engine transmission chain is a high-precision transmission part, so that high requirements are imposed on all parts forming the chain. The chain plate is one of essential parts in the chain assembling process, and the chain plate blanking quality is ensured to be one of the directions for improving the chain performance. The link joint quality difference of current mould blanking mainly embodies in two aspects: the chain plate is bent, and the flatness is more than 0.02 mm; the size difference of parts punched in the two times is large. The main cause of these problems is caused by the working principle of the continuous press mold: after the first sheet type blanking, burrs with the thickness of 0.1-0.3mm are remained on the periphery of the steel belt net material, and the burrs move forwards along with the net material; when carrying out the blanking of secondary blade type, burr on the net material is along with the steel band gets into in the second stripper, leads to two piece upper and lower locating plates can't fix a position the steel band to lead to the blanking quality poor. At present, in order to ensure the size uniformity of chain plates in the chain assembling process, management and control are carried out in the production process in a cavity-dividing and lane-changing mode, the mode seriously influences the production efficiency, and higher requirements are provided for the management and control of the production process.
The chain plate bending leads to the increase of the side clearance of the chain, so that the axial runout of the chain is increased in the actual operation process, and larger noise is generated; the size difference of the left cavity die and the right cavity die seriously influences the matching of relevant parameters of the chain, reduces the performance of the chain and prolongs the service life of the chain.
