Ningbo metal stamping parts processing plant, several kinds of stamping and drawing knowledge + stamping accuracy can reach 0.01mm

The technicians of Ningbo metal stamping parts processing plant have said that as one of the main stamping processes, metal stamping parts stretch forming is widely used. Various thin-walled parts with cylindrical, rectangular, stepped, spherical, conical, parabolic and other irregular shapes can be made by the stretching process. So today, Xiaoshuo is here to share with you, what are the types of metal stamping and drawing forming processes when using stamping equipment for metal stamping and drawing processing. 1. Deep drawing and stamping processing: The drawing processing products that exceed the drawing processing limit need to go through more than two times of multiple drawing to complete. The products that have been stretched in the depth direction of the front station are re-stretched in the depth direction. The wide flange stretched part is stretched to the required flange diameter when it is stretched for the first time, and the flange diameter remains unchanged when it is stretched later. 2. Taper drawing and stamping processing: For deep taper parts with h/d0.8 and α u003d10°～30°, due to the large depth, the deformation of the blank is greater, and only the local area of u200bu200bthe blank contacting the punch The transfer of the forming force can easily cause the blank to be locally excessively thinned and severely broken, and it needs to be gradually formed through multiple transitions. The step stretching method is to first stretch the blank into a stepped transition piece, whose stepped shape is tangent to the inner shape of the tapered part, and then expands to form a cone. The stretching times and processes of the stepped transition piece are the same as those of the stepped cylindrical piece. 3. Rectangular re-stretching and stamping processing: The deformation of the high rectangular part formed by multiple stretching is not only different from the stretching of the deep cylindrical part, but also very different from the deformation of the low box-shaped part. When the multi-station automatic conveying press is used to process high rectangular box parts, the shape and size of the part will change with the height of the stretch during the multiple stretching process.
