Abstract
The invention discloses a concrete mixer drum and a manufacture method thereof. The concrete mixer drum comprises a main drum, wherein one end of the main drum is fixedly connected with a front conical drum and the other end of the main drum is fixedly connected with a rear conical drum. The wall of the main drum is outwardly protruded to form a support roller track. The main drum is a spin-formed main drum, the front conical drum is a spin-formed front conical drum, and the rear conical drum is a spin-formed rear conical drum. The manufacture method of the drum comprises feeding all blanks into a spinning machine so as to be spun, performing spin forming of the main drum, the front conical drum and the rear conical drum respectively, and then suiting the front conical drum and the rear conical drum and welding the front and rear conical drums on the main drum. The support roller track is formed by outward protrusion of the wall of the main drum, simplifying the manufacture process and guaranteeing the precision in position of the support roller track on the drum. The drum is not easy to deform due to no match stress between the support roller track and the drum. All parts of the drum are spin-formed parts, thereby significantly enhancing the surface strength, improving the wear-resistant property of the drum and the prolonging the service lifetime of concrete mixers.
Description
Technical field
The present invention relates to a kind of cylinder and manufacturing approach thereof of concrete mixer.
Background technology
The cylinder of concrete mixer is the vitals of mixer, because the diameter of cylinder is bigger, and is rotary part, and machining accuracy is difficult to guarantee.The support roller track of cylinder periphery welding is annular workpiece, first, the support roller race way diameter is bigger, processing difficulties; The second, the support roller track with the cylinder welding process in positional precision can't guarantee, the rotation of cylinder is squinted, make cylinder produce axial force, quicken the wearing and tearing of support roller and support roller track axially stop block; Three, the support roller track with the cylinder welding process in be easy to generate welding stress, thereby make cylinder produce internal stress and deformation take place, the serious weld cracking that also can cause cylinder has shortened service life of concrete mixer.
Moreover; Concrete and drum inner surface frictional force were bigger when the cylinder of concrete mixer was worked, and very easily wearing and tearing are because the big volume of cylinder is bigger; Therefore can't carry out necessary case hardness intensive treatment to cylinder, this also is one of a lower reason in concrete mixer service life at all.
