Abstract
The invention discloses a blank manufacturing method of a tractor transmission, and belongs to the field of agricultural machinery. The blank manufacturing method comprises the following steps: (1) the tractor transmission is divided into upper and lower two parts according to a design drawing of the tractor transmission for respectively designing and manufacturing tractor transmission precoated sand molds; (2) the tractor transmission precoated sand molds are put on an automatic molding machine to manufacture a precoated sand pouring sand shell model and a sand core model; (3) the pouring is performed; and (4) a casting is taken out and cleaned. The blank manufacturing method has the characteristics of capability of efficiently realizing blank production of the tractor transmission, saving of materials and labors, reduction of the mechanical loading quantity, reduction of casting defects, improvement of the yield and easy realization of the automatic production.
