Problems solved by technology

However, in continuous die production, the strip cannot be turned over, and the other R angle can only be pressed from the back, which greatly increases the difficulty of unloading; 2. When punching nails, due to the large impact force, the product is prone to bending Deformation; and when cutting and separating the product at the end, it is not easy to discharge the product with an ordinary thimble

Abstract

The invention relates to the technical field of dies and discloses a manufacturing process of a continuous die for square washers. The manufacturing process of the continuous die includes the steps of S1, cutting steps for a blank; S2, pre-stamping the blank for precisely positioning a guide hole for a strip; S3, finish-stamping a middle hole in the blank; S4, pre-pressing corners of the middle hole in the blank; S5, pressing the two face pressure corners R of the middle hole in the blank; S6, stamping a nail for the blank; S7, scraping the middle hole of the blank; S8, cutting edges of the blank to obtain a finished square washer; S9, separating the finished square washer. In the step S5, a pressure corner male die for pressing the two face pressure corners R of the middle hole is provided with a single-face tilt angle; in the step S6, a nail stamping female die is fixed on a stripping plate, moves with one strip, and stamps a nail when the bottom of the die is ejected. The manufacturing process of the continuous die for square washers has the advantages that stripping is easier and bending deformation occurs rarely.

Description

technical field [0001] The invention relates to the technical field of moulds, and more specifically relates to a production process of a square washer continuous mold. Background technique [0002] Square washer is one of the hardware accessories of electro-acoustic speakers. Figure 1a , Figure 1b Shown is a typical square washer product, the part is SPHC with a material thickness of 3.0. The key part of the part is the punching nail, and the pressure R angle on both sides of the middle hole, and the middle hole requires a high degree of smoothness and precision. In the prior art, this type of product is mainly produced by a single-process mold, and the steps are divided into three processes: blanking-punching-pulling. During production, the efficiency is relatively slow, many machines are required, and workers are not easy to operate. Safety. As the demand for square washer products gradually increases, in order to meet the continuous improvement of production efficie...
