Description

Technical Field

[0001] The present application belongs to the technical field of capillary flanging, and in particular relates to an automatic device for capillary flanging. Background Art

[0002] Most analytical instruments use capillaries as connecting pipes. In order to ensure sealing and extend the service life of the pipes, flanging capillaries are generally used as the tail connection method. Compared with straight capillaries, the biggest feature of flanging capillaries is the flanging at the tail. The flanging capillary mouth is used with a blade ring, blade sleeve and pressure ring to greatly improve the sealing of the pipeline system and the stability of the connection system, and reduce the probability of capillary falling off and causing analysis interruption in a high-pressure environment. Therefore, it is widely used in the analysis and detection industry.

[0003] Most of the flanging technologies currently used are manually operated on the flanging machine using a fixture. Although the operation steps are simple, the processing precision and accuracy are relatively high. This process has the following shortcomings: 1. Slow speed and low efficiency: Because the capillary is small and slippery, the flanging operation needs to overcome friction to ensure that the capillary does not slip and can be pushed into the fixture. At the same time, it is also necessary to ensure that the capillary and the fixture remain vertical. Manual flanging is greatly affected by human subjective factors, and long-term operation is prone to fatigue. Each time the capillary is operated to fit the fixture, it is easy to cause the flanging tube to fail to meet the technical requirements and cannot be used due to human errors, resulting in scrapping and affecting the yield rate;

[0004] 2. Inaccurate positioning and asymmetric flanging: When flanging, it is generally necessary to align the tool head vertically. This operation step is easily caused by manual operation to cause asymmetric or elliptical flanging.

[0005] 3. Risk of burns: This process requires heating to soften the capillary and then shape it. Most heat conduction parts are made of metal products with good thermal conductivity. Manual operation can easily cause burns if not careful. Utility Model Content
