Dongguan stamping hardware shares with you how to quickly solve problems for customers with square tensile fracture-hardware

At the end of 2018, the master of Dongguan stamping hardware shared with you, when the customer's product is square stretched, what should be done when it breaks? ① The drawing depth is too large. If reducing the drawing depth to prevent rupture, first check other reasons. When the rupture cannot be prevented after solving other factors, then use the method of reducing the drawing depth and adding a finishing drawing process. ② The corner radius (rd) of the die is too small. When the square tube is drawn, the measure to prevent the side wall of the straight side from rebounding and recessing is generally used to stretch the drawbead, but this method has the defect of occurrence of drawbead scars. Therefore, when the drawbead is not used for deep drawing, as a measure for stretch forming, the gap is slightly smaller than the plate thickness, and at the same time, the drawing method is selected when the rd is too small. If cracks occur if the tensile limit is exceeded, the rd can be slightly increased and then the trial deep drawing can be performed. Dongguan stamping hardware, 15 years of craftsmanship, 5,000 square meters of factory area, 20,000+ sets of customized stamping die processing and production, product accuracy can reach 0.01MM. Quickly solve the time-critical problem of your stamping parts, solve your needs for the accuracy of stamping parts, and solve the quality of your stamping parts during mass production.
