How to obtain the position accuracy of stamping parts in stamping processing orders

The processing accuracy of stamping parts is determined by the degree of conformity between the geometric parameters of the part size, shape and position accuracy and the ideal geometric parameters of the drawing. This article will take you to understand how the drawing stamping parts manufacturer obtains the stamping parts in the stamping processing order The method of location accuracy. The accuracy of the position of the processed surface on other surfaces is mainly determined by the clamping of the workpiece. 1. Direct aligning and clamping is a clamping method that uses a dial indicator, marking plate or visual inspection to directly align the position of the workpiece on the machine tool. 2. Scribe line alignment and clamping. This method is to first draw the center/center line, symmetry line and the processing line of each surface to be processed on the blank according to the part drawing, then install the workpiece on the machine tool, and align the workpiece according to the drawn line The clamping position on the machine tool. This clamping method has low productivity, low accuracy, and high technical requirements for workers. It is generally used for processing complex and bulky parts in small batch production, or where the blank size tolerance is large and cannot be directly clamped by fixtures. 3. Fixture with fixture is specially designed in accordance with the requirements of the processed process. The positioning element on the fixture can quickly occupy the correct position of the workpiece relative to the machine tool and the tool. The positioning accuracy of the workpiece can be ensured without alignment. The clamping productivity is high and the positioning accuracy is high, but it is necessary to design and manufacture special fixtures, which are widely used in mass production.
