Abstract
The utility model discloses a non-welding waste gas purification and catalysis machine of an engine. In the prior art, the conventional waste gas purification and catalysis machine casing of the engine is formed by processing a cone body and a casing in a welding manner, multiple welding processing procedures are needed, and discontinuity and strength reduction exist during welding, and in order to ensure the quality of a welding area, multiple detection procedures are performed and a large number of working personnel are needed, which cause the situations that the procedures are various and the production efficiency is influenced. According to the utility model, the non-welding method is used for spinning the cone body and the casing of the catalysis machine into a whole, the front end and the rear end of the catalysis machine are connected by a hoop, so that the whole catalysis machine has no welding seams, light weight of an exhaust system component is realized, the dimensional precision, degree of finish and observability of the appearance of a workpiece are improved, polishing and grinding are not needed, dimensional change caused by secondary shrinkage is avoided, the manufacturing period of the catalysis machine is shortened, the production cost is reduced, and the defect that the air tightness and attractiveness are influenced caused by a welding seam appeared on the catalysis machine during the welding is overcome.
Description
Technical field
The utility model relates to a kind of welding engine exhaust purifying catalyst converter, belong to engine exhaust purifying catalyst converter manufacturing technology field.
Background technique
At present, conventional engine exhaust purifying catalyst converter housing all adopts the method machine shaping of welding with cone and housing in known technology, need multiple tracks welding manufacturing procedure, also have discontinuity, strength decreased during welding, for guaranteeing the quality of welding zone, must pass through Multi-channel detection, such as air tightness test, expose the soldering point surface, after middle temperature phosphating is processed, rust prevention by applying liquid material priming paint etc. need a large amount of staff, and operation is various and affect manufacturing efficiency.If welding quality is slightly poor, will affect catalyticing purifying effect, therefore, seek the catalyst converter of a kind of catalyst converter cone and housing welding seam, be a kind of promotion to the technological progress of catalyst converter, meaning of the present utility model just is this.
The model utility content
The purpose of this utility model just provides a kind of welding engine exhaust purifying catalyst converter, overcomes the shortcoming that the conventional engines exhaust purification catalyst needs the multiple tracks welding fabrication, improves catalyticing purifying effect.
For achieving the above object, the utility model has adopted following technical proposals: welding engine exhaust purifying catalyst converter, formed by catalyst converter front end and catalyst converter rear end, catalyst converter front end and catalyst converter rear end are comprised of cone and the housing that connects respectively, between catalyst converter front end and catalyst converter rear end, be provided with catalyst converter front end and catalyst converter rear end are fastenedly connected together anchor ear.
Take the utility model of above-mentioned measure, use the welding method that catalyst converter cone and housing spinning is in aggregates, the catalyst converter front end is connected anchor ear and is connected with the catalyst converter rear end, because whole catalyst converter no-welding-seam, can realize the lightweight of exhaust system component, improve the ornamental of product dimensional accuracy, degree of finish and outward appearance, do not needed polishing grinding also to shrink the dimensional changes that causes with regard to having avoided because of secondary.Shortened the manufacturing cycle of catalyst converter, reduced cost of production, overcome catalyst converter and in welding process, had weld seam and affect tightness and shortcoming attractive in appearance.
For further specifying the utility model, below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure shaft side figure figure;
Fig. 2 is the utility model plan view.
Embodiment
Shown in above-mentioned accompanying drawing, the utility model is comprised of catalyst converter front end 1, catalyst converter rear end 2, anchor ear 3, flange 4.Catalyst converter front end 1 is identical with the structure of catalyst converter rear end 2, and just the mounting point is different, and its sectional shape is circle, and is simple and clear in order to describe, and only the structure of catalyst converter front end 1 is described.As shown in Figure 1, catalyst converter front end 1 is comprised of with import and export 1-3 cone 1-1 and cylindrical shell 1-2, it is cylindric that cone 1-1, cylindrical shell 1-2 and import and export 1-3 are hollow, use in the preparation the spinning mode, cone 1-1, cylindrical shell 1-2 and import and export 1-3 are made an integral body, the level and smooth no-welding-seam in three connecting part is installed catalyst carrier in cylindrical shell 1-2, import and export 1-3 and be connected with flange 4 by screw thread.Between catalyst converter front end 1 and catalyst converter rear end 2, be provided with anchor ear 3, by anchor ear 3 catalyst converter front end 1 and catalyst converter rear end 2 are fastened together, thereby the catalyst converter that forms an integral body is as shown in Figure 2.
