Share the precision metal stamping parts blanking processing method

Today the author bring a blanking of precision metal stamping parts processing methods, this method can make both sides of the precision metal stamping parts without burrs, what method? The author first sell a imprison son here, let's article give you your answer. As is known to all, there are burrs generated is what we will form in the processing, want to get rid of it is to make great efforts one time, and, because the parting surface, the method of deburring with very frequent, especially our precision metal stamping parts products, usually, there will be a direction burr. And to remove it, need to adopt the method of pressure burrs, if not so, can only use the method of negative clearance blanking. Author share today pressing method of deburring half quantity cutting this way, we call it a 'negative space', punch than die. We want to make a convex moulded into the material to produce material is pressed into the die single flat Angle, then the amount of pressure into the punch is very main, generally is up 75% of the material thickness, below is the pressing process, pressing process is easy, but that is special. We know that the material is in one and a half quantity cutting condition, want to consider (1) is divided into three kinds of circumstances, virtual punch parts; (2), virtual die part; (3), the center portion of the virtual punch and die. The core of this is to use virtual punch and die for blanking, some of the material to its blanking itself to generate collapse Angle, is the core of pressing process. After pressing the status of the order to achieve precision metal stamping parts to the pressing process of blanking process is suitable for half the amount of pressure intake is a must, so light is not form a virtual punch, concave die, and once too deep, before they can be flat cutting off, so we want to avoid material bite will choose the negative clearance; Shape in the processing finished size of the separated this piece, after cutting the shape of the size and quantity of blanking punch size is almost the same, but with the average of blanking blanking or is there a difference in addition, we should under the edge of the negative clearance blanking die design in the stripper block, in case of stamping products is not smooth, if the product is small, it is not necessary. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts? Details: sharing details of stamping processing industry: precision metal stamping parts figure how to draw, please be aware that this several steps
