Detailed Description

The utility model provides a wear resistant calender roll. The technical solution of the present invention is described in detail below with reference to the accompanying drawings so that it can be more easily understood and appreciated.

The wear-resistant calendering roller comprises a calendering roller main body 1, a calendering roller surface 2 is arranged on the calendering roller main body 1, a spraying ceramic layer 3 is arranged on the calendering roller surface 2, and a plurality of circumferential wire drawing grooves 4 which are axially and uniformly spaced are arranged on the spraying ceramic layer 3.

The specific implementation process and principle description are as follows:

this calendering roller main part 1 only need adopt ordinary stainless steel roll body can, need not to adopt the comparatively expensive wear-resisting roll body of price, carries out the machine-tooling shaping of calendering roll surface 2 on stainless steel roll body, and its machine-tooling cost is lower.

At this time, the ceramic layer 3 is sprayed on the roll surface 2 so that the ceramic layer 3 is formed on the roll wall surface of the roll surface 2, and the circumferential wire drawing groove 4 is formed in the ceramic layer 3.

The sprayed ceramic layer 3 can provide excellent wear resistance, and simultaneously has the spraying protection effect on the main body 1 of the calendering roll, thereby prolonging the service life of the calendering roll.

The structure of the circumferential wire drawing grooves 4 with axial intervals is adopted, so that very reliable contact friction force can be provided, the slipping of a film material in the rolling process can be effectively prevented, in addition, the circumferential wire drawing grooves 4 can also give an axial extension effect to the film material in the rotating process of a rolling roller, specifically, in the rolling process, the circumferential wire drawing grooves 4 generate certain material extrusion accommodating spaces, and along with the rolling and the roller rotation, the extrusion material in the extrusion accommodating spaces can generate the extension along the rolling direction, so that the extension similar to a thread shape is formed, and the rolling effect is more remarkable.

In one embodiment, the thickness of the ceramic layer 3 is 0.1 mm-0.25 mm, the depth of the circumferential wire drawing groove is 10 μm-55 μm, and the width of the groove is not limited, and is set according to the contact friction force.

Specifically, the coating can be completely covered on the surface 2 of the rolling roller to form a profiling spraying layer, the peripheral wire drawing groove with a certain depth is formed on the spraying ceramic layer 3 to meet the requirement of contact friction force, the groove width is not more than 2 times of the groove depth generally, and the coating can be processed according to the requirement.

Circumference wire drawing groove 4 adopts radium carving fashioned mode promptly for radium carving wire drawing groove, can satisfy the precision finishing precision, is difficult for causing the damage to spraying ceramic layer 3 simultaneously, prevents effectively that spraying ceramic layer 3 from scrapping.

In a specific embodiment, as shown in fig. 1, a plurality of V-shaped rolling grooves 5 are arranged on the rolling roll surface 2 at intervals, a V-shaped rolling roll surface 6 is formed between adjacent V-shaped rolling grooves 5, and the circumferential wire drawing groove 4 is located on the V-shaped rolling roll surface 6, that is, the circumferential wire drawing groove 4 only acts on the contact surface.

Through the design of the specific pressing roller surface 2, the requirement for axial two-side extension is met, and the extension effect is more obvious.

Through the description, the wear-resistant calendering roller disclosed by the utility model has the advantages that the ceramic layer spraying and circumferential wire drawing groove matching design is adopted, the wear-resistant steel with high price is not required, the wear-resistant calendering roller has excellent wear-resistant property, the calendering and slipping can be effectively avoided, the protection and machining forming requirements of the stainless steel calendering roller main body are met, the manufacturing cost of the wear-resistant calendering roller is reduced, and the service life is prolonged. Through the cooperation of the V-shaped calendering roll surface and the circumferential wire drawing groove on the V-shaped calendering roll surface, the requirement of extension on two axial sides can be met, and the calendering effect is very obvious.
