Abstract

一种盘式硫化仪,由两个温度控制器,上、下两个 压盖,两个加热器,两个模体及等高垫,同时做测温和 控温用的铂电阻、轴承、传感器等构成。两个测温、控 温共用的铂电阻分别轴向放置于均热板和下模体中 并分别与两台温度控制器电联接,并用两个弹簧和导 热硅脂压住两个铂电阻使其尖端与安装孔底部紧密 接触。在下加热盘下面有三个等高垫。

Description

本实用新型涉及一种测量橡胶硫化程度的盘式硫化仪。
现有的盘式硫化仪,测温、控温采用间接控制方式,即测温和控温各用一个铂电阻,在上、下两个模体中就要用4个铂电阻。这种控温与测温分开的间接控制方式校正恢复时间长,易受环境温度干扰,测量误差大。
本实用新型的目的在于提供一种直接测量和控制模体温度的盘式硫化仪,改进了已有技术的不足。
本实用新型的任务是以如下方式完成的:将两个测温、控温共用的铂电阻分别轴向放置于均热板和下模体中,并分别与两台温度控制器电联接,并用弹簧和导热硅脂压住两个铂电阻使其尖端与安装孔底部紧密接触。
本实用新型的任务还以如下步骤进一步具体实现:在下加热盘下面有三个等高垫。
使用本实用新型提供的盘式硫化仪,能在室温下调整和标定。上、下两个加热器匹配,相差不超过15%,20分钟内升温即可达到设定温度,4分钟稳定,可达±0.1℃~0.2℃的水平。加入胶料后,模体温度只需1~2.5分钟即恢复到许可范围。上、下模体的升温和降温水平接近,相差1℃~2℃。提高了测温、控温的可靠性、稳定性。保证了试验曲线的一致性和重现性。另外,加热功率降至600瓦,模体温度达到195℃时,托板轴承座的温升为30℃~40℃。
下面结合附图对本实用新型作进一步叙述。
附图是本实用新型的结构剖视示意图。
圆形压盖1与圆形加热盘3之间有一加热器2,压盖1与加热盘3,均热板4与上模体5之间分别用螺钉紧固成一体,上模体5与下模体7中间有一转子6,下加热盘8,加热器9,压盖10。下加热盘8下面有三个等高垫11。托板12,主轴17,轴承套16,轴承座18中有轴承19,传感器20上有对称安放的应变片21。同时担当测温、控温用铂电阻22、13分别与两个温度控制器15电联接,并分别用弹簧23、14固定并压住两个铂电阻。三个等高垫11使下加热盘8与托板12脱开,减少温度干扰。

Claims (2)
