The present invention relates to vehicle clutches, and particular to clutch suction disk for an air compressor of a vehicle air conditioner and the method for manufacturing the same.
With reference to
Since the combination of the suction disk B and the disk D is by welding at several points, the welding will release due to vibration. A plurality of protrusions are formed on the bottom of the suction disk B and the upper side of the disk D for combining the two, but this will weaken the structure.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
Accordingly, the primary object of the present invention is to provide a method for manufacturing a clutch suction disk for an air compressor of a vehicle air conditioner, comprising the steps of: punching a solid round cylindrical steel bar so that the steel bar to be as a flattened steel cylinder; forming a recess in a central axis of the flattened steel cylinder by cool forge; expanding a bottom of the steel bar being expanded as a disk which is out of a lower end of the flattened steel cylinder; folding an outer side of the disk upwards so as to form an outer cylinder which encloses the flattened steel cylinder by a further cool forge; punching a bottom of the recess so that the bottom descends downwards to be lower than a bottom of the outer cylinder; and forming a round hole with a predetermined diameter; at the bottom of the recess.
Moreover, the present invention provide a suction disk manufactured by above methods.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details.
However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
The present invention relates to a clutch suction disk for an air compressor of a vehicle air conditioner and a method for manufacturing the same. The suction disk is formed integrally through a series of punching and forging.
The method for manufacturing a clutch suction disk for an air compressor of a vehicle air conditioner comprising the following steps:
Punching a solid round cylindrical steel bar; as illustrated in
Punching the steel bar again so that the steel bar is shorted; as shown in
Forming a recess 10 in an axial central portion of the flattened steel cylinder by cool-forge; and a bottom of the steel bar being expanded as a disk 20 which expands out of a lower end of the flattened steel cylinder; as shown in
Folding an outer side of the disk 20 upwards so as to form an outer cylinder 30 which encloses the flattened steel cylinder by a further cool-forge process; as shown in
Punching a bottom of the recess 10 so that the bottom descends downwards to be lower than a bottom of the outer cylinder 30;
Forming a round hole 40 with a predetermined diameter; at the bottom of the recess 10, as illustrated in
With reference to
The present invention causes the suction disk to be more stronger and has precise sizes. The material is less than the prior art suction disk with a quantity of 30%. Thereby, the cost is reduced greatly. The precision is higher than the prior art. Thereby, steel with uniform crystal structure can be used in the present invention. The crystals can be filled in all the structure so as to provide precise sizes. The forging process saves more material and the steps in the manufacturing process can be reduced so as to be an impact and fatigue endurance properties. In the present invention, no welding process is used. Thereby, the strength of the suction disk is preferred.
Furthermore, the present invention relates to an integral formed clutch suction disk for an air compressor a vehicle air conditioner made of above mentioned method. The integral formed clutch suction disk comprises a steel cylinder having a recess 10 through a central axis thereof; a disk expanding from a bottom of the steel bar as a disk which is out of a lower end of the flattened steel cylinder; an outer side 30 of the disk being folded upwards so as to form an outer cylinder which encloses the steel cylinder; A bottom of the recess is descended downwards to be lower than a bottom of the outer cylinder; and a round hole 40 with a predetermined diameter is formed at the bottom of the recess.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
