What are the types of drawing forming processes for metal stamping parts? +15 years of production capacity of 3 million punching the next day

Metal stamping parts Stretch forming, as one of the main stamping processes, 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, the small master of hardware will share with you what are the types of metal stamping and drawing forming processes: 1. Deep drawing and stamping processing: Stretching products that exceed the drawing processing limit need to go through more than two times. Multiple stretches can be completed. 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 forming force can easily cause local excessive thinning or even rupture of the blank, which requires multiple transitions to gradually form. 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. Figure 1-46 shows how the shape and size of the part changes with the height of the stretch during multiple stretches when the multi-station automatic conveying press is used to process high rectangular box parts. Hardware, 15 years of focus on metal stamping parts, 5000 square meters production workshop, hundreds of precision processing and production equipment, more than 20 Ru0026D and design engineers, monthly processing capacity of 100+ sets of molds and production capacity of 3 million punches per day, stamping accuracy can reach 0.01 mm, 16 quality inspections are strictly controlled. It can quickly solve the urgent problem of time when choosing hardware stamping processing, solve the problem of stamping accuracy, and solve the problem of production quality. For 15 years, I have been conscientious and dedicated to the results of your needs for the results of work!
