Mini roller press

Abstract

The invention relates to a mini roller press. To be particular, the roller press comprises: a housing (10) with a charge port (11) and a discharge port (13); a forming roller module (20) comprising a driving cylinder (21) placed in the housing (10) and used for compression forming of powder loaded via the charge port (11) and a driven cylinder (23) forming a pair with the driving cylinder (21); and a roll pressing device (30) which conducts pressure adjustment of the cylinders of the forming roller module (20) in case the load applied to the cylinders is too large so as to guide a part of or the whole displacement of the cylinders.

Description

technical field [0001] The present invention is as a kind of roller pressing device that puts used nuclear fuel or radioactive waste and other powders or powders and ordinary powders or powders into a certain size product (or semi-finished product) between rollers, and introduces a plurality of An elastic unit composed of coil springs. That is, the present invention relates to a micro-rolling machine. By arranging coil springs in the device, not only can the device become more compact, but also because there is no need to configure auxiliary equipment for the rolling device, it can be used even in a narrow room such as a hot room. It can also be easily set up and operated in the space. Background technique [0002] Korean Patent No. 1998-0008371 (hereinafter referred to as "prior art") discloses a rolling machine driving device, a rolling machine, and a rolling method as a rolling machine and a rolling machine according to the prior art. [0003] In addition, as a similar ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, in order to manufacture the above-mentioned hydraulic rolling mill, it is necessary to separately introduce auxiliary equipment such as oil tanks and pipes, which will increase the size of the device and increase the installation area.

[0008] In addition, there is a possibility of oil leakage from piping such as pipes used for supplying oil, so when handling flammable substances, it is easy to cause safety accidents such as fire.

[0009] In addition, it is difficult to perform proper maintenance work in confined spaces such as hot cells where highly radioactive materials are handled

[0010] In addition, as for the coil spring, compared with the hydraulic drive device, the load is applied to the driven roller by 1 to 2 coil springs, so the scale of the device is relatively small, but when the load pressure changes, it must be replaced with a suitable one. coil spring

At the same time, when the coil spring is damaged during use, there will be equipment operation failures such as operation stop
