How to modify the edge cutting die to improve stability
The mould of copper ring broaching machine includes upper mould and lower mould. The upper mould includes upper template, upper backing plate, concave and convex mould, bolt, handle and cutting rod. The concave and convex mould is provided with mould core.The spring is located between the concave and convex die and the upper discharge plate.The lower die includes the lower die plate, the lower base plate of the alloy die, the concave die and the lower base plate, which are installed on the deep drawing punch, the trimming punch and the ejector rod. The lower end of the trimming punch is positioned in the lower base plate, and the upper end of the ejector rod is in contact with the lower base plate.The lower end of the push rod is in contact with the elastic part.The copper ring of nut template deepens the gap, improves the production efficiency and the stability of product quality.The edge cutting die includes an upper plate and a lower plate which are mutually Mosaic, a lower plate guide column which is symmetrical to the corner of the lower plate, a middle plate between the lower plate and the upper plate, an upper pressing plate between the middle plate and the upper plate, and a product pressing plate between the middle plate and the lower mold plate.The product pressing plate is fixedly connected with the upper pressing plate through the connecting column of the product pressing plate on the middle plate, the product backing plate is arranged between the product pressing plate and the lower mould plate, and the edge cutting machine connected with the middle plate is arranged on the outer side of the product pressing plate.This product can cut off the die-casting casting once, that is, cut off the runner, slag bag, burr and so on, cut off the runner, slag bag and burr on the casting one by one, prevent the casting from deformation and ensure the quality of the product without manual intervention.Then, improve the finishing efficiency of die - casting parts.
