Background
In one working stroke of the press, the die for simultaneously completing more than two blanking processes at the same part of the die is called a compound blanking die. The basic structural form of the composite blanking die is a forward-loading composite die and a reverse-loading composite die. The composite die with the blanking female die arranged on the upper die is called a flip-chip composite die; the composite die with the blanking female die arranged on the lower die is called as a sequential composite die. The main advantages of the compound die are compact structure, flat product, general precision IT11-ITI0, and sometimes IT8. The common tolerance requirement is higher, and thin materials and soft material parts with difficult feeding and spacing are mostly punched by adopting a composite die. If the common parts are punched, a flip-chip compound die with a fixed die shank and a rigid pushing piece is adopted.
When the die descends, the blanking concave-convex die and the stripper plate need to press the woolen material at the same time, and under the condition that the upper die and the lower die of the die are dead, the stripper plate needs to be stuck to the blanking concave-convex die, so that good flatness of the punched product can be ensured, and the conditions of warping and irregular bright bands can not occur.
The existing transformer hardware composite stamping die has the following problems in the compacting materials: 1) The upper die plate descends to press the spring, so that the stripper plate is stuck to the blanking concave-convex die to press the woolen, but the spring is pressed to be too stressed, so that the service life of the spring is reduced; 2) The woolen is generally punched and then inserted into the positioning pin of the blanking concave-convex die, but excessive punching on the woolen can affect the beautiful appearance of the product.
