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

A kind of processing technology of high-precision metal plate belt pulley
Technical field
The present invention relates to a kind of processing method of belt pulley, more particularly, to a kind of processing work of high-precision metal plate belt pulley Skill.
Background technology
At present, processing method market disclosing such a sheet metal belt pulley, first by the roll bending punching press after launching Become pulley shape, then, reprocess belt pulley bearing position, because belt pulley bearing position adopts cutting way, easily by bearing position Upper harder surface cut is fallen, and have impact on the case hardness on bearing position, and the abrasion due to cutting tool, along with clamping becomes Shape, the surface roughness easily causing bearing position is relatively low poor with ovality.
Content of the invention
It is an object of the invention to provide a kind of can ensure that belt pulley bearing position case hardness, roughness and ovality are higher The processing technology of high-precision metal plate belt pulley.
For reaching above-mentioned purpose, a kind of processing technology of present invention high-precision metal plate belt pulley, comprise the following steps:
1.. blanking: first roll bending is flattened and strike out discoid blank;
2.. stretching: step discoid blank 1. is drawn into cup-shaped;
3.. reverse-drawing: step cup-shaped blank 2. is drawn into the semi-finished blank that shaft section is in m shape, and forms bearing Position;
4.. necking reverse-drawing: the bearing position on semi-finished blank is carried out stretch necking, to guarantee the wall on its bearing position Thick;
5.. punching: finally the bearing position bottom on semi-finished blank is punched out, is easy to short axle and passes through sheet metal belt Wheel.
Make the bearing position diameter that 3. step bearing position diameter 4. is formed less than step.
Described necking reverse-drawing includes shaping necking stretching, Surface hardened layer necking stretching, surface smoothness stretching and becomes Shape necking stretches.
Described Surface hardened layer necking stretching: necking is carried out to the outer surface on semi-finished blank, meanwhile, to semi-finished blank On outer surface and bearing position carry out Surface hardened layer.
Described reshape necking stretching: make bearing position diameter on semi-finished blank be less than surface smoothness stretching and formed Bearing position diameter.
After this technique, due to the bearing position on semi-finished blank is carried out with stretch necking it is ensured that its bearing position On wall thickness, need not again bearing position be processed, thus reach can ensure that belt pulley bearing position case hardness, roughness and ellipse The higher purpose of circularity.
Brief description
The present invention is described in further detail with reference to the accompanying drawings and examples.
Accompanying drawing 1 is a kind of each operation machining sketch chart of the processing technology of present invention high-precision metal plate belt pulley.
Specific embodiment
1. a kind of processing technology of high-precision metal plate belt pulley of the present invention shown in accompanying drawing 1, comprise the following steps:. blanking: First roll bending is flattened and strike out discoid blank;2.. stretching: step discoid blank 1. is drawn into cup-shaped;③. Reverse-drawing: step cup-shaped blank 2. is drawn into the semi-finished blank that shaft section is in m shape, and forms bearing position;4.. necking is anti- Stretching: the bearing position on semi-finished blank is carried out stretch necking, to guarantee the wall thickness on its bearing position;5.. punching: finally right Bearing position bottom on semi-finished blank is punched out, and is easy to short axle and passes through sheet metal belt pulley;Make step bearing position 4. straight The bearing position diameter that 3. footpath is formed less than step;Described necking reverse-drawing includes shaping necking stretching, Surface hardened layer necking is drawn Stretch, surface smoothness stretches and reshapes necking stretching;Described Surface hardened layer necking stretching: to the outer surface on semi-finished blank Carry out necking, meanwhile, Surface hardened layer is carried out to the outer surface on semi-finished blank and bearing position;Described reshape necking stretching: The bearing position diameter on semi-finished blank is made to be less than the formed bearing position diameter of surface smoothness stretching.
