Description
Technical Field
The utility model belongs to the technical field of surface treatment of steel backs of vehicle disc brake pads, and particularly relates to a CV disc brake pad steel back glue sprayer.
Background
In the production process of the automobile disc brake pad, a procedure is to glue or spray glue on the surface (gluing surface) of the steel back and the friction material, so that the steel back and the friction material are firmly bonded by heating and pressurizing in the subsequent hot pressing procedure.
The steel back of the small-sized light car disc type sheet (also called PV disc type sheet) is mostly provided with a plane surface, and the steel back is usually coated by adopting a roll coating method. Disc brake pads (also called CV disc type pads) of large-size commercial vehicles and medium-and heavy-duty vehicles mostly have special uneven surfaces such as spurs, welded nets, cast bosses and the like on the steel back, and the gluing uniformity is ensured by adopting a manual glue spraying mode or a glue spraying mode of a glue spraying machine.
The manual glue spraying is similar to the manual glue spraying, the glue spraying uniformity is related to the operation level, the labor intensity is high, and the manual glue spraying device is suitable for spraying glue on small-batch products; the glue spraying machine can guarantee stable product quality, has low labor intensity and is suitable for spraying glue on mass products.
The existing glue sprayer is formed by connecting a glue spraying chamber, a tunnel type heating furnace and a tunnel type cooling furnace in series. The working principle is as follows: at the inlet end of the glue spraying chamber, a plurality of steel back gluing surfaces are manually placed in trays, the trays are placed on a net chain or a conveying belt and then enter the glue spraying chamber, a plurality of fixed spray guns or a movable spray gun arranged on the glue spraying chamber spray glue on the steel back gluing surfaces, and then workpieces enter a heating furnace to be dried and enter a cooling chamber to be cooled. And at the outlet end, after the workpiece is manually taken out, the workpiece tray is cleaned and dried and then is conveyed to the inlet end, and the next cycle is started.
When the existing glue sprayer sprays glue, the vaporific glue can settle in a plurality of areas without workpiece coverage in the tray and on a net chain or a conveying belt outside the area of the tray, and the glue can not be recycled to cause waste of the glue;
the glue solution remained in the area covered by the tray without the workpiece can be hardened into a plurality of glue hard block areas with uneven heights after being heated and dried, if the glue hard block areas are not cleaned in time, the workpiece is influenced to be placed, and even the steel backing is inclined to be placed to influence the uniformity of glue spraying. Therefore, auxiliary processes of cleaning, drying and transferring the residual gum in the tray to the inlet end of the equipment need to be added, and a sufficient number of trays are prepared for turnover;
