A fixing device for the production of carbon-carbon insulation cylinder materials

Abstract

The invention belongs to the field of silicon single crystals, and particularly relates to a fixing device for manufacturing of a carbon-carbon heat preservation cylinder material. In the manufacturing process of existing heat preservation cylinders, a manufacturing material needs to be fixed and punched, and can be used after being subjected to punching forming. According to the prior art, the heat preservation cylinder is often not fixed stably, resulting in a large deviation in the punching forming size, and therefore the product yield is low. Proposed now is the following scheme: the fixing device comprises a base, wherein a fixed seat is fixedly installed at the top of the base, a fixed cavity is arranged on the fixed seat, a push rod motor is fixedly installed on the inner wall of the top of the fixed cavity, a pressing plate is welded to an output shaft of the push rod motor, and connecting plates are fixedly installed on both sides of the pressing plate. By means of the fixingdevice, the pressing plate is pushed to move by the push rod motor and power is generated, the heat preservation cylinder can be clamped and fixed, the fixing mode is firmer than the traditional fixing mode, and meanwhile, the yield of the heat preservation cylinder is improved.

Description

technical field [0001] The invention relates to the technical field of silicon single crystals, in particular to a fixing device for the production of carbon-carbon insulation cylinder materials. Background technique [0002] The silicon single crystal furnace thermal field system has a great influence on the single crystal yield, pulling speed and quality of the single crystal ingot. For silicon single crystal production enterprises, it is necessary to improve the utilization rate of silicon materials, reduce unit energy consumption, and improve production. Efficiency and reducing production costs have always been the goals pursued by enterprises. Therefore, the design of the thermal field system and the selection and use of key components in the thermal field have attracted much attention. The insulation cylinder is one of the key components of the silicon single crystal furnace thermal field system, and its main function is to reduce heat loss and control the temperature ...
