A fastener is a generic term for a class of mechanical parts that are used when two or more parts (or components) are fastened together. Depending on the use of different cold heading machines to produce different types of fastening equipment. The types of fasteners produced by the cold heading machine are bolts, studs, screws, …

Currently used for cold heading machine material, in many materials, the longest is divided into two categories: a black metal and nonferrous metals two categories. Cold heading machine materials are ferrous metals mainly include steel, carbon and some other materials. From the process point of view, the use of steel in the habit of the …

1, standard parts / fasteners manufacturing industry with bolts, nuts connected fasteners a lot, should ensure that it has enough preload, but it can not be tightened too tight. If the screw is too tight, on the one hand will make the joint under the action of external force to produce permanent deformation; the other …
As the cold heading machine is in the case of heavy load, continuous production, coupled with a higher degree of automation, and most of the body movement by the crankshaft or cam control for cyclical reciprocating motion or swing, so that the acceleration caused by the impact and impact Force is very large, and the …

1．硬件现场连接。将接近开关安装于设备上，依据电气原理图连接各部分元件。 2．参数设置。根据用户单位的要求，通过设定加减速时间参数（2202），将变频器启动频率由1Hz上升到50Hz（即电机转速由0r/min上升至1500r/min）所需的时间设置为3s。 3．加工试验。先在手动模式下启动设备加工零件，设备运行动作正确，改为自动模式。在计数器上设定加工零件的总数为30件，启动设备，当加工数量达到30件，设备停止运行。在手动和自动模式下，转动调速电位器，零件加工速度随之改变，数显表上显示出不同时期的速度。多工位自动冷镦机 4．急停和保持。按下控制柜操作面板上的急停按钮，设备停止运行。拉掉总电源，计数器上的数据保持不变。重新送电启动后，设备接着加工零件，直至达到预置数后停止。 5．复位。按动计数器操作面板上的两个复位开关，可以分别将预置数和加工数复位。 6．键保护。冷镦机，旋动钥匙开关（SA1）后，计数器操作面板上的按键操作均失效。
（1）冷镦机根据金属塑变理论，在常温下对金属坯料施加一定的压力，使之在模腔内产生塑变，按规定的形状和尺寸成型。 （2）冷镦机必须选优质“塑变”良好的金属材料，例如如铆螺钢，它的化学成分和机械性能是有严格的标准的。 （3）冷镦螺栓、螺母成型机械已经有多型号、多系列的机种。冷镦机设备性能可靠、效率高、产品质量稳定。 （4）冷镦机产品成型镦锻力大，配置动力在，设备一次投入大。因此生产规格M24以下最为经济。 （5）有较好的表面质量，较高的尺寸精度。冷镦机因在镦锻过程中存在着冷作硬化，变形量不应该太大。一定要减少开裂。 （6）冷镦机工艺适用范围于批量大、各类规格的产品，这样才能降低成本从而产生更大的效益。
