在用金刚石锯条将大理石荒料锯切成毛板的过程中,除对锯机的强度、锯框的运动方式和锯框进给运动调速范围有要求外,还须采取措施来保证锯条具有8～10吨的张紧力。锯条的张紧程度直接影响其寿命和加工质量,国外通常采用的张紧方法有四种。①楔块张紧:结构简单,但不能直接量测锯条的张紧力。也不能保证每根锯条的张紧程度一致。②螺栓张紧:由于锯条间距的限制,螺栓直径一般为M12。螺栓所受拉应力很大,必须采用高强材料,并作防锈处理。可用专
In the use of diamond saw blade marble blocks cut into wool board process, in addition to the strength of the saw, saw frame movement and saw frame feed movement speed range requirements, but also to take measures to ensure that the saw blade has 8 to 10 tons of tension. Saw blade tension directly affect the life and processing quality, there are four commonly used methods of tension abroad. ① wedge tension: the structure is simple, but can not directly measure the tension of the saw blade. There is no guarantee that the tension of each blade will be the same. ② bolt tension: Due to the spacing of the saw blade, the bolt diameter is generally M12. Bolt suffered a lot of tensile stress, we must use high-strength materials, and for anti-rust treatment. Available specifically
