Device for clearing and cutting fixed length of clad tube

Abstract

The invention belongs to automatic turning device design field, in particular discloses a device for clearing and cutting fixed length of clad tube. Two fixed length cutting means are sequentially installed along both ends of a cradle so as to cut fixed length of the two ends of the clad tube along two stations but not cut simultaneously, thereby, the axiality of the clad tube and a molding cutter can be ensured, the adjustment of the axiality during the producing can be achieved, the yield is improved. A detecting device is installed after tube drawing, cleaning, and fixed length cutting stations, thus increasing the production accuracy and the yield. The cleaning device and the fixed length cutting device are respectively provided with a protective cover to prevent the sprinkling of chips, in addition, a chip collector is arranged for centralizedly recovery processing the cutting chips and graphite dust, accordingly, the clean of the workpiece is ensured, the work environment is improved. A pneumatic damper is adopted by the cutting feeding for achieving the change from the rapid advance phase to the feeding, thereby, the invention has advantages of stable performance , high control accuracy, easy maintenance, convenient adjustment, no pollution, and convenient replacement and purchase.

Description

technical field [0001] The invention belongs to the design field of automatic turning devices, and in particular relates to a cleaning, cutting and length-fixing device. Background technique [0002] Cleaning and cutting the cladding tube to length is a key process on the CANDU-6 heavy water reactor nuclear fuel element assembly production line that determines the follow-up process. In order to meet the requirements of subsequent production, it is necessary to clean and Bevel cutting on the end face, and ensure that the overall length of the workpiece after cutting is within the required range. At present, there is no relevant manufacturing device in China, and the manual pure mechanical or hydraulic cutting device cannot guarantee the processing accuracy and cleanliness of the components, nor can it meet the requirements of the assembly line operation, and it is difficult to guarantee the processing accuracy and processing efficiency of the components. In addition, at pres...

Problems solved by technology

At present, there is no relevant manufacturing device in China, and the manual pure mechanical or hydraulic cutting device cannot guarantee the processing accuracy and cleanliness of the components, nor can it meet the requirements of the assembly line operation, and it is difficult to guarantee the processing accuracy and processing efficiency of the components

In addition, currently foreign (such as Canada, South Korea, etc.) heavy water reactor nuclear power fuel elements are manufactured using fully automatic cutting-to-length devices, but foreign equipment has neither public technical reports nor relevant patent documents for reference
