If small bending radius difference matter soon to the material thickness, small cutting machine must be a bottom die forming.
Bending machine cut gasket adjustment and shorten the preparation time.
when the choose and buy of small cutting machine once the improper selection, production costs will rise, small cutting machine has not expected to recover costs. That is, the shorter the machine requires less shim adjustment, will be able to produce qualified parts. Parts of using free bending, bending radius bending machine bending radius of concave die openings from 0. 156 times. In terms of free bending, convex die and concave die according to the 85 ° or less than 85 ° processing ( A bit as well) 。 If most of the workpiece is five feet or more shorter, tonnage bad matter soon by half, so as to greatly reduce the purchase cost. In the process of bending, die opening distance should be 8 times the thickness of the metal material. Using this set of mold, punch and die in clearing idle at the bottom of the stroke, and compensate the springback and keep material around 90 ° of flexion. If most of the work is the thickness of the 16 the gauge length, big 10 feet of low carbon steel, so free bending force not greater than 50 tons. You can get from cutting machine manufacturers machine ton meter, the table shows that under different thickness, different material per foot length required tonnage estimates. Therefore, there are several factors to weigh in decision-making. The material brand is also a key factor. If less than the thickness of the material, the bending radius should be used in bending machine front of punch radius less than the thickness of the material, and turn to stamping bending method. So, it is need to 10 times the free bending stress. Artifacts is the first to consider important matters you want to production parts, the point is to buy a short and able to complete processing of workbench, small tonnage of the machine. However, a bottom die forming the required pressure about four times larger than the free bending. Usually, free bending die on the new cutting machine of springback Angle 2 ° or less, bending radius equal to the die opening from 0. 156 times. Well, assume that material is 1/4 inch thick, 10 feet free bending need 200 tons, and a bottom die bending ( Calibration curve) Need at least 600 tons. Torsion change under the same load, the workbench and the slider 10 feet's flexible change is 5 feet machine 4 times. In the bottom of the stroke, intensive should have a slightly larger than the material thickness of the gap between. For a bottom bending die, die Angle generally is 86 ~ 90 °. Compared with low carbon steel, stainless steel need to load usually increased by about 50%, while most of the brand of soft aluminum reduced about 50%. For example, using 16 1/2 inch opening from forming the gauge low carbon steel, parts of the bending radius is about 0. 078 inches. To improve the forming Angle, because a bottom die bending large tonnage ( About four times that of free bending) And reduce the bending radius fan
. Parts to determine the length of the specifications of the new machine is very important. However, if it is engaged in a lot of a bottom die forming, maybe a 160 tonnage of the machine tool should be considered. Carefully consider material brand and big thickness and length of processing.
