Embodiment Construction

[0021] Referring to the accompanying drawings, a solder paste uploading device for a metal honeycomb carrier includes a pneumatic propulsion device 1 for solder paste and a negative pressure recovery device 2 for solder paste. The pneumatic propulsion device 1 for solder paste includes a bracket on which A storage mold 3 is erected, and a step hole 4 is arranged on the storage mold 3. The aperture of the step hole 4 is large and small, and a cylinder 5 is set under the storage mold 3, and the piston rod extension end of the cylinder 5 is vertically upward. And the protruding end is fixedly installed with the piston 6 matching the diameter of the lower hole of the stepped hole 4, the upper hole of the stepped hole 4 is used to fix the metal honeycomb carrier, and the piston cylinder structure is formed between the lower hole and the matched piston 6, and the piston cylinder The solder paste is placed in the cavity of the body structure, and the sliding and sealing fit between th...

Abstract

The invention discloses a device and method for uploading a soldering paste of a metal honeycomb carrier. The device comprises an air pressure propelling device used for uploading the soldering paste, and a soldering paste negative pressure recovery device. The method is a method that brazing is carried out by coating the soldering paste after rolling and forming, and the method comprises the following steps: rolling a flat wave strip into the metal honeycomb carrier; placing the formed metal honeycomb carrier on the air pressure propelling device used for uploading the soldering paste, so as to push the soldering paste into the metal honeycomb carrier; placing the metal honeycomb carrier filled with the soldering paste upside down to be delivered into the soldering paste negative pressure recovery device to recycle redundant soldering paste; and finally placing the metal honeycomb carrier containing small amount of soldering paste in clearance into a vacuum brazing room to be welded. The device for uploading the soldering paste of the metal honeycomb carrier is reasonable in structure design, and the method is simple and feasible, so that not only the soldering paste cannot generate plugged holes in a carrier pore canal, but also the condition that the soldering paste is discharged and pressed can be reduced, and soldering flux is saved, thereby rational utilization of resources can be achieved, and meanwhile, the welding strength is improved, and the quality of products is guaranteed.

Description

technical field [0001] The invention relates to the field of metal honeycomb carriers, in particular to a solder paste uploading device and method for metal honeycomb carriers. Background technique [0002] Welding between the flat corrugated strips in the inner core of the metal honeycomb carrier: the traditional process all uses BNi-5 welding strips to be sandwiched between the flat corrugated strips when the metal honeycomb carrier is rolled. After the rolling is completed, the metal honeycomb carrier is made by vacuum brazing The flat-wave ribbons of the inner core are connected to each other. This method has disadvantages such as complex production process, easy breakage of solder ribbons, and low efficiency. And the welding ribbon is continuously wound between the flat wave belts. The welding belt only plays a welding role at the contact point between the top of the wave belt and the flat belt. Exhaust resistance, after improvement, the method of rolling the solder pa...
