Technical Field

Background
Hinges, also known as hinges, are mechanical devices used to connect two solids and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material. The platen is shaped so that one end is a hinge flexure and the other end is a semicircular hook, as shown in figures 1 and 2. The compression object is bound through the hinge connection. The thickness of the pressing plate is 2mm, the pressing plate is made of 08F materials, and the distance between the center of the hinge and the center of the semicircular hook is large and different. The principle of hinge edge rolling adopts a push-round method, a vertical edge rolling die is used, but the length of a hinge product is different according to different purposes of a hinge, when the vertical edge rolling die is used, different requirements can be met on the closing height of a machine tool, the pressure required for edge rolling of the hinge product is very low, but the hinge product is forced to be designed and manufactured into a die with a large closing height due to the fact that the hinge product is very long, the machine tool machining product with a high closing height and a large relative tonnage is selected, the cost for manufacturing the die and the cost for using equipment are increased, and each hinge product needs to be designed and manufactured into one edge rolling die, so that the hinge edge rolling die is not suitable for a small-batch. At present, more than ten hinge products with different material thicknesses, lengths and rolling diameters adopt a traditional vertical rolling die structure, the design and manufacturing cost of each set of die is 1.5 ten thousand yuan, the design and manufacturing cost of the rolling die for the hinge products is 20 ten thousand yuan every year, and the types of devices required to be used are multiple.
