Technical Field

[0001] The invention relates to relevant parts on a burring machine, in particular to a supporting roller of the burring machine with a wear-resistant nano coating. Background Art

[0002] The deburring machine is a necessary equipment for the color coating production line. It is normally only used to flatten the seams and seams on the steel strip. The stamping burrs on the seams and seams are too large and may damage the roller surface of other equipment. If the steel strip is damaged along the edge during the previous process or transportation, especially at the beginning and end of each roll, the burrs will be raised. At this time, the deburring machine needs to flatten the raised burrs.

[0003] The support roller assists in the transmission and flattening operations in the deburring machine. After being used for more than one month, the surface of the support roller will wear out, and the worn area will scratch the surface of the steel strip plate, causing surface quality problems.

[0019] like Figures 1 to 5 As shown, the present invention provides a support roller of a burring machine with a wear-resistant nano-coating, comprising a roller sleeved on a central shaft 1,

[0020] The roller includes an outer cylinder 3 and an inner cylinder 2. The inner cylinder 2 is sleeved on the central axis 1, and the outer cylinder 3 is sleeved on the inner cylinder 2. The cross section of the inner cylinder 2 is a rounded triangle, which can ensure that the inner cylinder 2 drives the outer cylinder 3 and avoid the phenomenon that the three corners of the triangle are too thin and vulnerable to damage. The outer cylinder 3 includes a cylinder 301, a wrapping layer 302 wrapped on the outside of the cylinder 301, and a nano-composite coating coated on the outer surface of the wrapping layer 302. The outer surface of the inner cylinder 2 is in contact with the inner surface of the cylinder 301, wherein the wrapping layer 302 is a tin plate.

[0021] The inner cylinder 2 and the cylinder 301 are made of the same material, both of which are nickel-based alloys, and the material density of the inner cylinder 2 is the same as that of the cylinder 301.

[0022] The roller has a first fixing cover 4 and a second fixing cover 5 at both ends, and the first fixing cover 4 and the second fixing cover 5 are sleeved on the central shaft 1. The first fixing cover 4 and the second fixing cover 5 are connected to the inner cylinder 2 by screws 6.

[0023] The first fixed cover 4 and the inner cylinder 2, the second fixed cover 5 and the inner cylinder 2, the first fixed cover 4 and the outer cylinder 3, the second fixed cover 5 and the outer cylinder 3, and the inner cylinder 2 and the outer cylinder 3 are all detachable, and the inner cylinder 2 and the outer cylinder 3 are separately arranged. When cracks occur on the outer cylinder 3 or the surface of the outer cylinder 3 is severely worn, the outer cylinder 3 can be directly replaced by the following method without replacing the entire roller.

[0024] The replacement method of the outer cylinder 3 is as follows: loosen the screw 6 on the first fixing cover 4, contact the connection between the screw 6 and the inner cylinder 2, then remove the first fixing cover 4, then directly take off the outer cylinder 3, replace it with a new outer cylinder 3, and then re-sleeve the first fixing cover 4, so that the first fixing cover 4 fits the inner cylinder 2 and the outer cylinder 3, and then tighten the screw 6 to form a fixed connection between the first fixing cover 4 and the inner cylinder.

[0025] The outer surface of the cylinder 301 is provided with a grid-like groove body, and the cross-section of the groove body is an isosceles triangle, wherein the length of the first side 3011 is equal to the length of the second side 3012, the height of the third side of the isosceles triangle is greater than or equal to 20μm and less than or equal to 50μm, and the angle between the first side 3011 and the second side 3012 is greater than 15° and less than or equal to 65°. The cylinder 301 and the wrapping layer 302 are bonded by glue, and the grid-like groove body can effectively increase the contact surface between the glue and the outer surface of the cylinder 301, thereby enhancing the connection strength between the cylinder 301 and the wrapping layer 302.

[0026] The nano-based layer 303 is coated on the outer surface of the wrapping layer 302, and the nano-protective layer 304 is coated on the nano-based layer 303 to form a nano-composite coating.

[0027] The thickness of the nano-composite coating is greater than or equal to 100 μm and less than or equal to 150 μm. The nano-composite coating includes a nano-based layer 303 and a nano-protective layer 304, wherein the nano-based layer 303 is a laser-clad NiBCr-WC alloy coating, and the nano-protective layer 304 is formed by plasma spraying a WC nano-ceramic material doped with nano-lanthanum oxide particles, wherein the WC nano-ceramic material doped with nano-lanthanum oxide particles can adopt a nano-structured ceramic (n-WC-12Co) coating material doped with nano-lanthanum oxide particles, and the content of nano-lanthanum oxide is 4%-9%.

[0028] The support roller of the burring machine with wear-resistant nano coating described in this embodiment has a roller surface hardness of HRC80-85 and a roller surface roughness of Ra0.8-1, and its service life can reach 300 days.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several similar modifications and improvements without departing from the creative concept of the present invention, and these should also be regarded as within the scope of protection of the present invention.
