图1所示为一台搓丝机,在搓4.2×13毫米的材质为不锈钢和耐酸钢的钢板螺钉时,生产率可达600件/分;而且,搓丝板的寿命反而比在200件/分时还高。这主要是由于采用了可靠的、凸轮控制的送进与推入装置,它能稳定地把坯料送到固定丝板与活动丝板之间,并能确保每次只送入一个坯料。此外,该机在搓带尖的木螺钉时,能自动地将螺钉与废料分开。在调整搓丝板时,由于滑块能作“寸动”行程,比较方便。另外,从图1中可以看
Figure 1 shows a thread rolling machine, rubbing 4.2 × 13 mm made of stainless steel and acid-resistant steel plate screws, the productivity of up to 600 / min; and, however, the life of the screw plate instead of 200 pieces / Time-sharing is also high. This is mainly due to the use of reliable, cam-controlled infeed and in-feed units that deliver the stock steadily between the stationary and moving plates and ensure that only one stock is fed at a time. In addition, the machine can automatically separate the screws from the waste material when tapping the pointed wood screws. In adjusting the screw plate, the slider can be “inch” stroke, more convenient. In addition, it can be seen from FIG. 1
