Embodiment 1

[0044] A continuous spinning forming method for sheet metal spinning pulleys with unequal diameters, wherein there are N=4 small-diameter V-shaped grooves and M=4 large-diameter V-shaped grooves on the outer ring of the unequal-diameter sheet metal spinning pulley groove, the forming method of the unequal-diameter sheet metal spinning pulley includes blanking, deep drawing, shape correction, punching, edge trimming, material distribution and spinning forming processes, the blanking, deep drawing, shape correction, punching Hole, edge trimming, and material distribution process are the same as the above-mentioned steps of the forming method of the conventional unequal-diameter sheet metal spinning pulley with V-shaped grooves on the outer rim, and will not be repeated here.

[0045] The described spinning forming process is a continuous spinning forming process. First, use 5 pairs of preforming wheels with small-diameter U-shaped grooves and large-diameter U-shaped grooves at th...

Embodiment 2

[0060] The invention relates to a continuous spinning forming method of spinning belt pulleys made of sheet metal with unequal diameters whose material dividing process is spinning.

[0061] This embodiment is a further improvement on the implementation of Example 1. It connects the common material distribution process and the spinning forming process of the present invention into a continuous spinning forming process, which includes material distribution spinning and spinning forming two steps, the said sub-spinning is to send the yu-shaped pulley blank into the sub-spinning mold for sub-processing, and make the yu-shaped pulley blank with a 'Y' shape on the edge. The spinning forming process is to use a pre-formed wheel with a small-diameter U-shaped groove and a large-diameter U-shaped groove to pre-spin the 'Y'-shaped Yu-shaped pulley blank, and then use a small-diameter V-shaped pulley blank. The forming wheel of the V-shaped groove and the large-diameter V-shaped groove ...

Abstract

The present invention relates to a continuous rotary extrusion forming method for a waney metal-plate rotary extrusion belt pulley with the outer wheel circle being provided with a V-shaped groove, and comprises the procedures of feeding, extension, shape correction, perforation, edge cutting, distribution and rotary extrusion forming; at the rotary extrusion forming procedure, a pre-forming wheelwith a small-diameter U-shaped groove and a large-diameter U-shaped groove is used to perform the rotary extrusion on the Y-shaped cup-shaped belt pulley roughcast of an edge belt after the distribution procedure, and then a forming wheel with a small-diameter V-shaped groove and a large-diameter V-shaped groove is used to perform the forming rotary extrusion so as to be made into a formed wheelof a waney metal-plate rotary extrusion belt pulley; the value range of M and N is: M is more than or equal to 1 and is less than or equal to 10, and N is more than or equal to 1 and less than or equal to 10. The belt pulley that is produced with the forming method hereinabove has good dynamic and static balancing performance, and guarantees the size requirements when simultaneously driving two elements; the jumping consistence of the circle of the V-shaped groove surface is good; at the same time, the processing method also has the advantages of long service life of the distributing wheel andthe forming wheel, simple processing procedures and short processing period.

Description

Technical field: [0001] The invention relates to a processing method of a belt pulley in a mechanical transmission part, in particular to a continuous spinning forming method of a spinning belt pulley made of unequal diameter sheet metal. Background technique: [0002] As an important mechanical transmission part, the V-groove pulley is widely used in various mechanical transmission equipment such as automobiles, agricultural machinery, and textile machinery. The traditional manufacturing process of the V-groove pulley is made by cutting the casting blank. The belt pulley made by this method is not only heavy but also has a large moment of inertia, high energy consumption in starting and braking, and a large amount of metal materials must be removed in the process of processing, which not only wastes materials but also has poor production conditions. , pores, etc.), so each pulley needs to be balanced, so the production efficiency is low and the cost is high. [0003] At pr...
