一、零件的功用 穿簧机是软垫家具专用设备中的一种。该机的功用是将弹簧钢丝绕成圆柱弹簧丝,然后将它穿在垫簧的上下两端,使垫簧有规律地排列并成为一体。缠绕模是穿簧机上的一个成形件,是使钢丝成为弹簧式的主要零件,而且也是一个易损件,需要用耐磨的高强度材料制成。为此选用了GT35钢结硬质合金材料,此材料规定热处理硬度为HRC65～71,甚至还可以更高。零件的形状如图1所示。 First, the function of parts wear spring machine is a kind of special equipment for upholstered furniture. The machine’s function is to wrap the spring steel wire into a cylindrical spring wire, and then put it on the upper and lower ends of the spring, so that the spring is regularly arranged and integrated. Wrapping dies are a forming part on a spring machine that makes the wire spring-loaded as a primary part, but also as a consumable part that needs to be made of wear-resistant, high-strength material. This selection of GT35 steel bonded carbide material, this material provides heat treatment hardness of HRC65 ~ 71, and even higher. The shape of the part is shown in Figure 1.
