Abstract
The utility model relates to a hydraulic assembly cover (1) for a rear case used for a miniature tractor. The utility model is characterized in that original iron castings are replaced by steel stampings; the surface of the utility model has a rectangular concave structure (2); the back side of the utility model has a corresponding rectangular convex structure (3); the periphery of the utility model has vertical edges (4). The steel cover has the advantages of simple manufacture, high efficiency, material saving and low cost.
Description
The utility model belongs to cabinet parts behind the tractor with small four wheels.
At present, hydraulic pressure rear cover assembly leakproof oil cap plate in the back cabinet that tractor with small four wheels is used is one and cuts shoulder rectangle cast iron plate that this plate has certain thickness, if the casting that reduces cost is a little thin, it is higher then to produce percent defective.
For overcoming above-mentioned defective, its production technology has been done improvement, makes a kind of steel plate punching press cover plate.
The utility model is so improved, and back cabinet hydraulic pressure assembly cover plate (1) adopts steel plate to be stamped to form, and stamps out indent structure (2) in the surface, and its back side shows corresponding evagination structure (3), the upright edge (4) of periphery compacting one circle of plate.
Change ironcasting into steel stamping part, make simply, technical indicator is not less than ironcasting, and cost descends.
