Calendering machine for molybdenum wafers

Abstract

The invention discloses a calendering machine for molybdenum wafers. The calendering machine comprises a support rod, a pressing disc, a movable extension disc, a chassis, a lead, a movable rod, a control cabinet, a display screen, a diameter limiting device, a positioning device, a bracket, a base, an extension bracket rod, a first diameter limiting disc, a second diameter limiting disc, an extension rod, a vibration reducing spring and an extension disc. The calendering machine has the following beneficial effects: the positioning device is mounted in the device, and the extension bracket rod of the calendering device extends to control, so that the position of the pressing plate is not limited during calendering, and the position deviation condition cannot be generated. The diameter limiting device is mounted in the chassis; the movable extension disc is arranged below the pressing disc; and through a matching effect with the first diameter limiting disc and the second diameter limiting disc in the diameter limiting device, the diameters of the calendered molybdenum wafers are limited, so that the molybdenum wafers calendered by the device can be calendered according to preset diameters, and the uniform specifications are guaranteed. The device has the characteristics of higher sensitivity and capability of autonomously controlling the diameters of the calendered molybdenum wafers.

Description

technical field [0001] The invention relates to a calender, in particular to a calender for molybdenum discs, and belongs to the field of industrial processing equipment. Background technique [0002] Molybdenum is a metal element. Molybdenum has the characteristics of high temperature resistance. Adding molybdenum to alloy steel can improve the elastic limit, corrosion resistance and permanent magnetism of the metal. Therefore, it is mainly used in the steel industry, most of which Therefore, industrial molybdenum oxide is directly used for steelmaking or cast iron after briquetting, and is smelted into ferromolybdenum and molybdenum foil for steelmaking, and a small part is also used in the production of semiconductor power electronic devices. Among them, the packaging of ultra-high-power thyristors adopts a press-junction process, and the chips of high-voltage and high-current semiconductor devices are all matched with alloy molybdenum wafers, and are packaged in ceramic ...

Problems solved by technology

[0003] However, the existing devices for grinding molybdenum discs still have certain defects in use, and the working efficiency of the device is not high, and powdery molybdenum disc debris is prone to appear in the grinding process. If these debris are not processed in time, Not only will it affect the normal operation of the device, but it will also interfere with the grinding effect, so that the surface smoothness of the polished molybdenum discs cannot meet the requirements, and the molybdenum disc debris has not been recycled and reused, which is wasteful
