Abstract

The utility model discloses a conduction oil heating roller, comprising a roller axle, an axle sleeve sleeved with the excircle of the roller axle and an oil path formed by a spiral groove and arranged on the excircle of the roller axle, wherein an oil inlet and an oil outlet of the oil path are respectively arranged on two end surfaces of the roller axle and the oil path is a reverse double oil path formed by crossing two spiral grooves; simultaneously an annular oil path is respectively arranged on the two ends in the roller axle. The rolling technology applied on the battery pole is used, so as to ensure the thermal deformation uniformity of the roller axle roller surface, keep the good linearity of the roller surface, increase the rolling quality of the battery pole and simultaneously increase the effective using width of the roller axle roller surface.

Description

A kind of heat-conducting oil heating roller

Technical field

The utility model relates to a kind of heat-conducting oil heating roller, especially a kind of rolling heat-conducting oil heating roller of battery pole piece that is used for.

Background technology

Referring to accompanying

drawing

1,2, present heat-conducting oil heating roller is for singly advancing singly to go out circulating oil path, oil inlet end can be slightly higher than oil outlet end temperature on the roll surface width relatively, therefore between roll surface B, C relatively large convexity can appear, and A and D, B and C are not reciprocity, thereby the linearity to roll surface causes harmful effect, can't satisfy the high-precision requirement of battery pole piece rolling mill practice; In addition, because roll shaft both ends of the surface area of dissipation is relatively large, the temperature at roll surface two ends can be on the low side relatively, and thermal expansion is less than normal, roll surface collapse angular breadth A, D section broad, thus reduced effective use width of roll surface.

The utility model content

The technical problems to be solved in the utility model provides a kind of heat-conducting oil heating roller, be applied to the rolling mill practice of battery pole piece, can guarantee the uniformity of roll shaft roll surface thermal deformation, the good linearity that keeps roll surface, improve the rolling quality of battery pole piece, can increase the roll shaft roll surface simultaneously and effectively use width.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of heat-conducting oil heating roller, comprise roll shaft and axle sleeve, axle sleeve is sleeved on the excircle of roll shaft, the excircle of roll shaft is provided with the oil circuit that helicla flute constitutes, the oil-in of oil circuit and oil-out are separately positioned on two end faces of roll shaft, oppositely two oil circuits that described oil circuit constitutes for the double spiral groove cross arrangement.

As to improvement of the present utility model, two oil-in I and two oil-out I of described reverse pair of oil circuit are arranged in a crossed manner respectively on two end faces of described roll shaft.

As to improvement of the present utility model, on the close excircle at both ends of described roll shaft an annular oil circuit is set respectively respectively.

As to improvement of the present utility model, the oil-in II of described two annular oil circuits and oil-out II are positioned on the side end face of described roll shaft separately.

Adopt the beneficial effect that technique scheme produced to be: the utility model mid portion is the opposite spiral circulating oil path of both direction, all there are an oil-in and an oil-out in the roll shaft two ends, make roll shaft axial temperature unanimity after the turnover oil temperature stack, guaranteed the uniformity and the good linearity of roll surface of roll surface thermal deformation; Two ends of the present utility model are provided with two independently annular circulating oil paths, have improved the heating efficiency at roll surface two ends, thereby remedied the heat leakage of roll shaft both ends of the surface, have reduced the collapse width at angle of roll surface, have increased effective use width of roll surface.

The specific embodiment

Referring to accompanying

drawing

1,2, existing heat-conducting oil heating roller is for singly advancing singly to go out circulating oil path, oil inlet end can be slightly higher than oil outlet end temperature on the roll surface width relatively, therefore between roll surface B, C relatively large convexity can appear, and A and D, B and C are not reciprocity, thereby the linearity to roll surface causes harmful effect, can't satisfy the high-precision requirement of battery pole piece rolling mill practice; In addition, because roll shaft both ends of the surface area of dissipation is relatively large, the temperature at roll surface two ends can be on the low side relatively, and thermal expansion is less than normal, roll surface collapse angular breadth A, D section broad, thus reduced effective use width of roll surface.

Referring to accompanying drawing 3, comprise roll shaft 1 in the structure of a specific embodiment of the utility model; Roll shaft 1 inside is provided with oppositely two oil circuits 2, and these oppositely two oil circuits 2 are the reverse cross arrangement of double helix, and two oil-in I 21 and two oil-out I 22 of oppositely two oil circuits 2 are arranged in a crossed manner on two end faces of described roll shaft 1; Roll shaft 1 inner two ends are provided with respectively on the oil-in II 31 of 3, two annular oil circuits 3 of an annular oil circuit and the side end face that oil-out II 32 is positioned at roll shaft 1 separately.

Referring to accompanying drawing 4, operation principle of the present utility model is: the utility model roll shaft 1 mid portion is the opposite spiral circulating oil path of both direction, all there is an oil-in I 21 and oil-out I 22 of oppositely two oil circuits 2 at roll shaft 1 two ends, make roll shaft 1 axial B section temperature unanimity after the turnover oil temperature stack, guaranteed the uniformity and the good linearity of roll surface of roll surface thermal deformation; Two ends of the present utility model are provided with two independently annular oil circuits 3, have improved the heating efficiency at roll surface two ends, thereby remedied the heat leakage of roll shaft both ends of the surface, have reduced the collapse width of angle A, C of roll surface, have increased effective use width of roll surface.

Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the single restrictive condition to its technical scheme itself.
