Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a fixing clamp for a heating lamp tube. Background Art

[0002] At present, the SLS molding method in 3D printing technology is basically inseparable from the assistance of heating lamps. The heating lamps are fixed on the workbench or in the working chamber by lamp clips, and the heating lamps are used to preheat the workbench or the building chamber to provide a constant temperature environment to ensure that the printing material can be kept in a suitable temperature range during the printing process, thereby improving the printing quality and success rate. Heating lamps are generally protected or heat-conducting efficiency is improved by coating the surface with a gold-plated layer. Figure 8 The figure shows a commonly used fixed lamp clamp. The clamping claws of this type of fixed lamp clamp are relatively wide, and the contact area with the heating lamp is large. The clamp itself will accumulate heat during 3D printing. When the printing work stops, if the clamp cannot quickly dissipate the heat, the heat of the clamp will continue to be transferred to the heating lamp tube, thereby aggravating the volatilization of the surface coating of the heating lamp tube and affecting the service life of the heating lamp.

[0003] The utility model is made based on the above situation. Utility Model Content
