我厂生产的一种直径近六米的转盘,其滚道需要淬火,而厂内无大的淬火设备。后来我们自行设计制造了专用淬火设备,使用效果很好。现介绍如下:工件转盘是一项科研试验设备上的主要零件(图1),它工作时承受重载荷。其材料为ZG45铸钢,由两个半圆形拼成,重量为32吨。上滚道为方形槽,下滚道为弧形槽,滚道表面硬度不低于HRC42。淬火装置淬火装置由淬火器、焰炬、装夹机构、行走机构及定位装置组成。(1)淬火器:专用淬火器(图2)是用紫铜板制成的,分为气室和水室,中间用板隔开,互不渗漏。两室底面分别钻 I plant a diameter of nearly six meters of the turntable, the raceway needs to be quenched, while the factory without large quenching equipment. Later, we designed and manufactured a special quenching equipment, the use of good results. Now introduced as follows: Workpiece turntable is a research and test equipment on the main parts (Figure 1), which work under heavy load. The material is ZG45 cast steel, composed of two semi-circular, weighing 32 tons. The upper raceway is a square groove, the lower raceway is an arc groove, and the raceway surface hardness is not lower than HRC42. Quenching device quenching device consists of quencher, torch, clamping mechanism, walking mechanism and positioning device. (1) quencher: dedicated quencher (Figure 2) is made of copper plate, divided into gas chamber and water chamber, the middle board separated, mutual leakage. Bottom of the two chambers were drilled
