s6, arranging a reticulate pattern or a spline on the outer diameter of the right section:

arranging a reticulate pattern: automatically feeding the raw materials processed in the step S5 through a multi-tapping automatic feeder, prepressing the right end of a tungsten steel die into the outer circle of a reticulate pattern blank, and performing secondary processing and molding on the chamfer at the left end and the diagonal angle of the square of the left middle section or the outer circle of a spline according to the leveling requirement;

and (4) spline setting, namely, automatically feeding the raw materials processed in the step S5 through a multi-tapping automatic feeder, prepressing the raw materials into the excircle of a spline blank by using a tungsten steel die, secondarily processing and molding the chamfer at the left end and the opposite angle of the four directions of the left middle section or the excircle of the spline according to the leveling requirement, and simultaneously stretching and forming the spline at the right end.

2. The process for manufacturing a pulley shaft of a washing machine according to claim 1, wherein the raw material in step S1 is 45 # steel.

Technical Field

The invention relates to the production field of belt pulley shafts of washing machines, in particular to a production process of the belt pulley shafts of the washing machines.

Background

The washing machine is a cleaning appliance for washing clothes by utilizing mechanical action generated by electric energy, the washing machine is an essential appliance for modern life, the existing washing machines can be generally divided into impeller type, roller type, stirring type, jet flow type, double-acting type and inclined barrel type, wherein the impeller type and the roller type are widely applied, the pulley shaft is an important part in the existing washing machine, the traditional production process of the pulley shaft generally needs more people to carry out multi-step processing on the pulley shaft, the time consumption is longer, the working efficiency is lower, and the processing efficiency is lower, so the production process of the pulley shaft of the washing machine is designed to solve the problems.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a production process of a belt wheel shaft of a washing machine.

In order to achieve the purpose, the invention adopts the following technical scheme:

a production process of a belt wheel shaft of a washing machine comprises the following steps:

s1, surface treatment: carrying out phosphating treatment on the surface of the raw material;

s2, blanking: automatically feeding the raw material obtained in the step S1 through a multi-tapping automatic feeder, and automatically cutting off the raw material according to a set length;

s3, chamfering: automatically feeding the raw material cut in the step S2 through a multi-tapping automatic feeder, and pre-pressing the raw material into an R angle or an oblique angle by using a tungsten steel die;

s4, stretching the left front section filament blank: automatically feeding the raw material chamfered in the step S3 through a multi-tapping automatic feeder, and prepressing the raw material into an outer circle by using a tungsten steel die;

s5, a left middle section square or involute spline: stretching the left front section wire blank in the step S4, then automatically feeding the stretched left front section wire blank through a multi-tapping automatic feeding machine, and prepressing the stretched left front section wire blank into a square or spline by using tungsten steel;

s6, arranging a reticulate pattern or a spline on the outer diameter of the right section:

arranging a reticulate pattern: automatically feeding the raw materials processed in the step S5 through a multi-tapping automatic feeder, prepressing the right end of a tungsten steel die into the outer circle of a reticulate pattern blank, and performing secondary processing and molding on the chamfer at the left end and the diagonal angle of the square of the left middle section or the outer circle of a spline according to the leveling requirement;

and (4) spline setting, namely, automatically feeding the raw materials processed in the step S5 through a multi-tapping automatic feeder, prepressing the raw materials into the excircle of a spline blank by using a tungsten steel die, secondarily processing and molding the chamfer at the left end and the opposite angle of the four directions of the left middle section or the excircle of the spline according to the leveling requirement, and simultaneously stretching and forming the spline at the right end.

Preferably, in step S1, the raw material is 45 # steel.
