有许多农具及工具都具有锥尖,在制造这些产品时,锥尖加工常采用手工逐个磨削,不但加工质量差,而且生产效率低,劳动强度大。为此,我们研制出一种脉冲式径向挤压头及成形机。用于加工钢叉叉尖。经生产实践已取得良好效果。现将脉冲式径向挤压头工作原理及结构简要介绍如下。一、工作原理采用热挤压成形工艺。将工件欲加工的端部加热至可锻温度(约1000～1100℃),然后用如图1所示两个相同的挤压模块对工件加热端部进行挤压,挤压过程为:两个挤压模块绕工件端部轴线回转,在回
There are many tools and tools have cone tip, in the manufacture of these products, the tip processing often use manual grinding one by one, not only poor processing quality, but also low productivity, labor-intensive. To this end, we have developed a pulsed radial extrusion head and forming machine. For processing fork prongs. The production practice has achieved good results. Pulsed radial extrusion head now works and the structure is briefly described below. First, the working principle of hot extrusion forming process. The end to be machined is heated to a forgeable temperature (about 1000-1100 ° C), and then the heated end of the workpiece is extruded using two identical extrusion modules as shown in Figure 1, with two The extrusion module swivels around the end of the workpiece, back in
