用热压法生产金刚石钻头，准确地掌握烧结过程中的压缩量是十分重要的一环，为此，我们研制了一种观测压缩量的行程表。通过两年来生产实践表明，效果良好，现介绍如下：一、结构及原理该表由信号发送和接收装置两个部分组成。信号发送装置在烧结炉上的安装位置如图1所示，由自整角机（9）和安在自整角机轴上的小齿轮（10）以及上端固定在滑动梁（6）上，下端插入底盘（11）通孔中，并与小齿轮（10）相啮合的小齿条（8）等主
The production of diamond drill bits by hot pressing and accurate grasping of the amount of compression in the sintering process are very important. For this reason, we have developed a schedule for observing the amount of compression. Through two years of production practice shows that the effect is good, are introduced as follows: First, the structure and principle The table consists of two parts of the signal sending and receiving devices. The installation position of the signal sending device on the sintering furnace is shown in Fig. 1. The sizing machine (9) and the pinion (10) mounted on the sizing shaft and the upper end are fixed on the sliding beam (6). The lower end is inserted into the through hole of the chassis (11), and the small rack (8) engaged with the pinion (10) is mastered.
