Embodiment Construction

[0013] Referring to the accompanying drawings, the flame spraying clamping device on the surface of the roller includes a long axis 1, two flanges, an elastic member, an adjusting sleeve 6 and an adjusting nut 7. Both flanges are set on the long axis and are divided into fixed Flange 2 and movable flange 8, the fixed flange is fixed at one end of the long axis, the movable flange can move freely in the length direction of the long axis, the outer side of the movable flange is connected with one end of the adjustment sleeve through elastic parts connection, the other end of the adjustment sleeve is connected with the adjustment nut, and the adjustment nut is threaded with the long shaft.

[0014] The present invention is further improved, the movable flange is generally in the shape of a truncated cone, and its taper α is between 15-30°, 15° being the best, and the inner diameter of the roller to be clamped is between the diameter of the upper end surface and the lower end surfa...

Abstract

The invention discloses a roller surface flame spraying and clamping device and an assembling method of the roller surface flame spraying and clamping device. By the adoption of the roller surface flame spraying and clamping device and the assembling method of the roller surface flame spraying and clamping device, thermal expansion is effectively released, the phenomenon that heat on the surface of a roller is not dissipated evenly is eliminated, the problems that a spraying layer is prone to cracking and the roller is prone to deformation are solved, production scheduling can be more flexible, the requirements of a production line can be better met, the number of spare parts of the production line is reduced practically, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a roller surface flame spraying clamping device and an assembly method thereof. Background technique [0002] The flame spraying method of the roller surface of the traditional hot-rolled laminar flow cooling roller is to spray on the turntable after the roller, the shaft head, the flange, etc. are assembled and welded. The following problems exist when spraying the surface of the roller after assembly and welding: [0003] (1) Since the flange and the inner wall of the roller are welded together after assembly, the strain cannot be released after thermal expansion, causing the roller to deform and bend; the place where the flange contacts the inner wall of the roller dissipates heat quickly during spraying, causing the sprayed coating here Cracks and rework, the above two defects make the yield of the traditional spraying method only 80%. [0004] (2) The size of the rol...
