Abstract
The invention discloses a technology for machining a high-precision metal plate belt wheel. The technology for machining the high-precision metal plate belt wheel aims to solve the problems that according to an existing technology for machining the high-precision metal plate belt wheel, because cutting of the hard surface of a bearing seat is prone to occurrence, the surface hardness on the bearing seat is influenced, and meanwhile due to the facts that a cutting tool abrades the bearing seat and clamping deformation is caused, the surface roughness and the surface ovality of the bearing seat are prone to being poor. The technology for machining the high-precision metal plate belt wheel comprises the steps that firstly, a rolled plate is pressed to be flat and is stamped into a disk-shaped blank; secondly, the disk-shaped blank is stretched into a cup-shaped blank; thirdly, the cup-shaped blank is stretched into a semi-finished blank with the axial section being in an M shape, and a bearing seat is formed; fourthly, stretching and necking are conducted on the bearing seat on the semi-finished bearing seat, so that the wall thickness on the bearing seat is guaranteed; finally, the bottom of the bearing seat on the semi-finished blank is punched, so that a short shaft conveniently penetrates through the metal plate belt wheel.
Description
Technical field
The present invention relates to a kind of processing method of belt pulley, relate in particular to the processing technology of a kind of high-precision metal plate belt pulley processed.
Background technology
At present, a kind of like this processing method of sheet metal belt pulley is disclosed on market, first the roll bending after launching is struck out to belt pulley shape, then, reprocessing belt pulley bearing position, because belt pulley bearing position adopts cutting way, easily surface cut harder on bearing position is fallen, affected the case hardness on bearing position, again due to the wearing and tearing of cutting tool, add clamping deformation, easily cause the surface roughness of bearing position lower poor with ovality.
Summary of the invention
The object of this invention is to provide a kind of processing technology that can guarantee the high-precision metal plate belt pulley processed that belt pulley bearing bit table surface hardness, roughness and ovality are higher.
For achieving the above object, the processing technology of a kind of high-precision metal plate of the present invention belt pulley processed, comprises the following steps:
1.. blanking: first roll bending is flattened and struck out discoid blank;
2.. stretch: step discoid blank is 1. drawn into cup-shaped;
3.. reverse-drawing: step cup-shaped blank is 2. drawn into the semi-finished product blank that shaft section is M shape, and forms bearing position;
4.. reducing reverse-drawing: to the reducing that stretches of the bearing position on semi-finished product blank, to guarantee the wall thickness on its bearing position;
5.. punching: finally punching is carried out in the bearing position bottom on semi-finished product blank, be convenient to minor axis through sheet metal belt pulley.
Make step bearing position diameter 4. be less than the bearing position diameter that 3. step formed.
Described reducing reverse-drawing comprises that shaping reducing stretches, reducing stretching is hardened on surface, surface smoothness stretches and reshapes reducing stretching.
The sclerosis reducing of described surface stretches: the outer surface on semi-finished product blank is carried out to reducing, meanwhile, the outer surface on semi-finished product blank and bearing position are carried out to surface sclerosis.
Describedly reshape reducing and stretch: make bearing position diameter on semi-finished product blank be less than the surface smoothness bearing position diameter forming that stretches.
Adopt after this technique, due to reducing that the bearing position on semi-finished product blank is stretched, guarantee the wall thickness on its bearing position, without again bearing position being processed, can guarantee belt pulley bearing bit table surface hardness, roughness and the higher object of ovality thereby reach.
brief description of the drawingsbelow in conjunction with drawings and Examples, the present invention is described in further detail.
Accompanying drawing 1 is each operation machining sketch chart of the processing technology of a kind of high-precision metal plate of the present invention belt pulley processed.
detailed description of the invention1. the processing technology of a kind of high-precision metal plate of the present invention shown in accompanying drawing 1 belt pulley processed, comprise the following steps:. blanking: first roll bending is flattened and struck out discoid blank; 2.. stretch: step discoid blank is 1. drawn into cup-shaped; 3.. reverse-drawing: step cup-shaped blank is 2. drawn into the semi-finished product blank that shaft section is M shape, and forms bearing position; 4.. reducing reverse-drawing: to the reducing that stretches of the bearing position on semi-finished product blank, to guarantee the wall thickness on its bearing position; 5.. punching: finally punching is carried out in the bearing position bottom on semi-finished product blank, be convenient to minor axis through sheet metal belt pulley; Make step bearing position diameter 4. be less than the bearing position diameter that 3. step formed; Described reducing reverse-drawing comprises that shaping reducing stretches, reducing stretching is hardened on surface, surface smoothness stretches and reshapes reducing stretching; The sclerosis reducing of described surface stretches: the outer surface on semi-finished product blank is carried out to reducing, meanwhile, the outer surface on semi-finished product blank and bearing position are carried out to surface sclerosis; Described surface sclerosis reducing stretches: described in reshape reducing and stretch: make bearing position diameter on semi-finished product blank be less than the surface smoothness bearing position diameter forming that stretches.
