Embodiment 1

[0034] Such as figure 1 , 2 A kind of equipment for applying solder 1 on metal corrugated belt 2 shown in and 3, this equipment comprises: be used for the feeding device 10 of metal corrugated belt 2, be used for the solder of metal corrugated belt 2 positioning application solder 1 An application unit 11, and a gas cooling device 8 for solidifying the solder. The solder applying unit 11 includes a material chamber 15 for containing solder powder or a mixture of solder powder and a binder, and a material feeding chamber 12 communicating with the material chamber 15 . A rotating blade 4 is fixed in the feeding chamber 12, and the rotating blade 4 is connected with a motor for controlling its rotation. The bottom of the feeding chamber 12 is provided with an opening 7 for entering liquid solder, and the opening 7 is located below the rotating blade, so that the liquid solder 3 in the feeding chamber 15 can flow into the feeding chamber 12 under the agitation of the rotating bl...

Embodiment 2

[0040] The specific scheme is the same as in Example 1, the difference is that the gas cooling device 8 used to solidify the solder is changed to a hot air drying device, and the hot air drying device is used to provide hot air at 50°C to 100°C for solder powder and normal temperature adhesive mixture is dried. The hot air drying device in this embodiment is a hot air blower, and since the hot air blower is not the focus of the improvement of the present invention, it will not be described in detail.

Embodiment 3

[0042] Adopt the equipment of embodiment 1, select the wide solder nozzle 9 of 10mm for use, and as image 3 The way in which is arranged in the solder applying unit 11, so that the solder is fixed at a predetermined position. Add 1000 g of pure solder powder into the material chamber 15, and the whole process of applying solder is carried out under the protection of argon gas. Turn on the power supply of the heating device 14, set the temperature of the heating device to 1150° C. and start heating. After the solder powder melts into a molten state, turn on the motor connected to the rotating blade 4 to make the rotating blade 4 start to rotate, observe the solder outflow situation in the solder nozzle 9, and adjust the rotational speed of the rotating blade 4 so that the solder flow in the solder nozzle meets the process requirements. Start the feeding device 10 of the metal corrugated belt, make the metal corrugated belt pass smoothly above the solder application unit 11 at...

Abstract

The invention belongs to the technical field of vehicle exhaust purification, and specifically relates to a method for applying soldering fluxes to metal corrugated ribbons and a device for implementing the method, wherein the metal corrugated ribbons to which the soldering fluxes are applied are preferably used for manufacturing metal honeycomb carriers for vehicle exhaust purifiers. The device for applying soldering fluxes to metal corrugated ribbons comprises a feeding device of metal corrugated ribbons, a soldering flux application unit for positioning the metal corrugated ribbons so as to carry out soldering flux application, and a gas cooling device or a heated-air drying device for solidifying the soldering fluxes. The method for applying soldering fluxes to metal corrugated ribbons is implemented mainly through the following step: applying soldering flux powder or a mixture consisting of the soldering flux powder and a binding agent to the metal corrugated ribbons by using the soldering flux application unit so as to form soldering fluxes solidified on or adhered to the wave crests or troughs of the metal corrugated ribbons. By using the method and device provided by the invention, the defects in the prior art, that the soldering fluxes are easy to fall off in the process of soldering flux application and the application strength of the prepared product is not enough, are overcome.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas purification of motor vehicles, and in particular relates to a method for applying solder on a metal corrugated belt and equipment for realizing the method. The metal corrugated belt applied with solder is preferably used to manufacture metal for motor vehicle exhaust gas purifiers. Cellular carrier. Background technique [0002] Metal honeycomb carrier is widely used in the exhaust system of gasoline engine and diesel engine as the carrier of catalyst material. It has the advantages of fast light-off, small size, high strength and good heat resistance, and is most widely used in motorcycle exhaust purification. In consideration of the service life and use cost of the metal honeycomb carrier, the metal carrier uses a solder application method in a specific area. [0003] The invention patent with publication number CN 1147780A describes the use of adhesives to bond solder powder to metal stru...
