A sliding block oil film lubrication structure and its section steel drawing car

Abstract

The invention discloses a sliding block oil film lubrication structure. The sliding block oil film lubrication structure is characterized by comprising oil grooves which are formed in four corners, right opposite to positions above sliding blocks, of the upper surface of a steel drawing cart body. Connecting screws are connected to the bottoms of the oil grooves in a vertically upward and threaded mode. The lower ends of the connecting screws are connected into the sliding blocks in a penetrating mode. The lower surface of each sliding block is provided with an upwards concaved oil film groove. A vertical hole is formed in the middle of each connecting screw and communicated into the corresponding oil film groove. A mounting boss is arranged on the upper surface of each sliding block and installed in a mounting groove in the lower surface of the cart body in a limiting mode. The invention further discloses a section steel drawing cart adopting the sliding block oil film lubrication structure. According to the sliding block oil film lubrication structure and the section steel drawing cart, the hollow screws with the simple structure are used for realizing connection and installation of the sliding blocks and oil supply to the oil grooves, so that the lubrication degree is improved, frictional wear is reduced, and running smoothness of the steel drawing cart is guaranteed; meanwhile, the section steel drawing cart can realize mechanical steel drawing, is simple in structure, does not have electric failures and is connected with a steel wire rope more quickly and reliably.

Description

technical field [0001] The invention relates to a steel drawing car for an inspection platform in a section steel production line, in particular to a sliding block oil film lubrication structure and the steel drawing car for the section steel. Background technique [0002] Sectional steel refers to bar-shaped steel with a certain cross-sectional shape and size. During the production of section steel, after rolling and forming, it needs to go through hot sawing, cooling in a cold bed, straightening by a straightening machine, cold sawing and other processes. The inspection table is located on the assembly line behind the cold sawing machine, and is used to inspect the section steel to see if it meets the standard, and to paste the qualified label. [0003] A profiled steel inspection platform currently used by the applicant includes an input roller table composed of several input rollers arranged side by side and horizontally arranged at intervals, an output roller table comp...
