Devices for slag removal

摘要

A system for removal of slag during laser cutting of a hypotube by a laser cutting system may include a cooling system and a cooling fluid inlet regulator. The cooling system may be configured to be coupled to a laser nozzle of a laser cutting system. The cooling system may include a supply of gas and a gas inflow valve configured to regulate the gas that flows into the laser nozzle from the supply of gas. The cooling fluid inlet regulator may be configured to inject cooling fluid into an inner lumen of a hypotube during laser cutting by the laser cutting system at a velocity configured to facilitate removal of slag generated during the laser cutting of the hypotube. The cooling fluid inlet regulator may be configured to cool the hypotube during the laser cutting.

1. A system for removal of slag during laser cutting of a hypotube by a laser cutting system, the system comprising:
a laser nozzle configured to flow gas onto an external surface of a hypotube during laser cutting, a gas cooling system, a water inlet regulator; and a slag collecting device, wherein the gas cooling system comprises:
a gas supply;a connection member fluidly coupling the gas supply and the laser nozzle; anda gas inflow valve positioned along the connection member, wherein the gas inflow valve is configured to regulate the gas that flows into the laser nozzle from the gas supply through the connection member, and wherein the water inlet regulator comprises:
a source of water;a plurality of water injection tubes coupled to the source of water and configured to be coupled to an end of the hypotube, the plurality of water injection tubes arranged in series, with a diameter of each successive water injection tube being smaller than the preceding water injection tube;a pressure valve configured to flow water through the plurality of water injection tubes; anda water inlet gate configured to inject the water into an inner lumen of the hypotube at a velocity configured to facilitate removal of slag generated during the laser cutting of the hypotube, wherein the external water inlet regulator is configured to cool the hypotube during laser cutting, and wherein the slag collecting device is configured to collect the removed slag.
