Deep-hole plug

Abstract

The invention relates to a deep-hole plug, which comprises an aluminum plug end and a second plug end welded together with the aluminum plug end. The deep-hole plug is obvious in plugging effect, easy in control of a welding process and long in service life.

Description

technical field [0001] The invention belongs to the field of precision machinery, and relates to a blocking device, in particular to a deep hole plug. Background technique [0002] In engineering installation, some reserved technological openings are required to be permanently blocked after the parts are manufactured. For example, there is a relatively large aluminum frame part with a weight of 3.5 kg. The size of the aluminum plug is relatively small and the weight 1 g. At present, when the aluminum plug is installed into the aluminum frame, due to the influence of factors such as high welding temperature and welding time during welding, the aluminum plug quickly melts and flows into the hole, resulting in failure to seal or although most of them will be The opening is blocked, and there are still some gaps. In some precision-controlled continuous fields, such gaps or failure to weld often cause irreparable mistakes. For example, for aircraft, it includes damage to major ...

Problems solved by technology

[0003] At present, in such a field of micro-technology welding, especially at the same time as welding, it is difficult to control the size of the welding shape directly in the surfacing hole

Due to the limitations of various welding conditions, it is often impossible to achieve a permanent connection. If the method of bonding is used, degumming will also cause connection failure during long-term use.
