The present invention relates to the work roll that the cold-rolling aluminium figured plate band uses and the manufacture method of roll, especially relevant with the work roll that cold rolling two-sided patterned aluminum strip is used.
The patterned aluminum strip has excellent noise elimination, sound insulation, heat dispersion, extensively use finishing work in recent years with luxurious facility, wall finishing and ceiling furred ceiling as luxurious hotel, dance hall, dining room, broadcasting studio, recording studio, theater, telephone box, reach the decoration of palace car, vehicle cab, the liner of low temperature refrigerator, refrigerator.This sheet material not only result of use is good, and the life-span is long, and especially two-sided aluminium checkered plate has better result of use.
Two-sided aluminium checkered plate all is to have negative and positive to cooperate rolling the forming of working roll of decorative pattern with a pair of surface usually, the result of use of diamond plate is relevant closely with the quality of diamond plate with the life-span, requires the surface area of diamond plate big, the figure line is clear, distortion evenly, does not allow and rolls phenomenon.
The working roll that the most generally uses is the identical patterned roll of a pair of hardness at present, and the two-sided aluminium checkered plate that shuts out with this working roll can obtain decorative pattern clearly, but because the hardness of two rollers is identical, so the decorative pattern on the roll surface will be distinguished processing separately.For avoiding two-sided aluminium checkered plate goods to roll or burr appears in pattern edge or floral designs are unintelligible, perhaps even damage the roll surface decorative pattern, must be strict with the corresponding ridge design of the upper working rolls and lower working rolls unanimity that fits like a glove.Guarantee up-down rollers decorative pattern unanimity, all adopt programme controlled laser or spark machined operation processing roll respectively at present.Obvious this processing method, not only need big, the expensive equipment of technical difficulty, as: laser, spark erosion equipment and computer, and because decorative pattern is careful, the design pattern various programs of establishment that need wide in variety, the difficulty of program composition is also big, and this certainly will will improve the manufacturing cost of roll.
The objective of the invention is to design a pair of working roll that a kind of cold rolling two-sided patterned aluminum strip is used.This decorative pattern to the working roll body surface has fabulous negative and positive cooperate degree, is easy to make.
Another object of the present invention is the manufacturing process that will propose the working roll that a kind of new cold rolling two-sided patterned aluminum strip uses, this manufacturing process is simple and reliable, cost is low, and the equipment that must heavy price and the decorative pattern of the working roll body surface that instrument is made have fabulous negative and positive cooperate degree.
The cold rolling two-sided patterned aluminum strip recruitment of the present invention's design comprises two rolls that hardness number is different as roll, and the body surface of two rollers has the ridge design that is the negative and positive cooperation, and pattern depth is the 0.1-0.4 millimeter.One is hard roller in two rolls, and another is soft roller, and soft roller is a composite roll, is made up of roller core and cladding, and the hardness of cladding is starkly lower than roller core.
The invention allows for the processing technology of a kind of cold rolling two-sided aluminium checkered plate, comprise and make hard roller and make soft roller operation with work roll.Make hard roller operation by making smooth roll, on body of roll working face, draw grid, forming towards texturing line, deburring.Soft roller manufacturing process by make roller core, on the roller core surface vertically and radially working groove, add the surface coating layer, with the soft roller of hard roll-in; Form the cloudy decorative pattern of hard roller on soft roller surface.
The cold rolling two-sided patterned aluminum strip recruitment of design is made roll and is made up of a hard roller and a soft roller.The body surface of each roller has the ridge design that negative and positive cooperate that is of certain depth respectively, and floral designs can be selected as required, as all birds paying homage to the phoenix, prosperity brought by the dragon and the phoenix, The Goddess Chang'e flew to the moon.Hard roller is made by general steel roll material.As No. 45 steel of 40Cr or cold-rolled steel roll material etc.Soft roller is a composite roll, comprise roller core and cladding, the effect of roller core is to guarantee that working roll has enough intensity, roller core be steel rider can be identical with hard roller also can be different, the diameter of roller core influences the intensity and the working life of soft roller, diameter is less than yielding in the use of the then soft roller insufficient strength of 1/2 soft roller diameter, diameter is greater than 3/4 soft roller diameter, then cladding can extend loosening at work and can't use, and therefore, the roller core diameter should be controlled between the 1/2-3/4 of soft roller diameter.The soft roller that diameter is big, its roller core diameter can take off limit value, and diameter is little answers the capping value.Cladding selects for use aluminum or aluminum alloy to make, and uses the aluminium alloy of a little higher than desire processing of hardness aluminium sheet to do the use that cladding can improve soft roller and receives a mandate, and is convenient to again form decorative pattern on soft roller surface.
The roller processing technology of the present invention's design comprises to be made hard roller and makes soft roller operation.Make the hard burnishing-in roller of required size earlier with the general material of making the steel roll, line forms the grid of regular arrangement in length and breadth on the body of roll again, on each lattice, use the decorative pattern of steel seal drift punching out setting then successively, the decorative pattern depth capacity can reach 0.4 millimeter, remove the burr wedge angle after, promptly make the figuratum hard roller in surface.Soft roller is the composite roll of being made up of roller core and cladding, use the material similar to make roller core earlier with hard roller, at the radially and axial working groove of the body surface of roller core, then at roller core surface casting one deck aluminum or aluminum alloy cladding, the aluminium of fusion or aluminium close the groove that towel fills up the roller core surface, can prevent cladding in the radial and axial slip in roller core upper edge, will form the soft roller of light face behind the car light of cladding surface.Hard roller and soft roller are contained on the milling train of roll machinery Synchronous Transmission, between upper and lower roll, apply certain pressure with screwdown gear, two rollers increase drafts gradually in operation process, decorative pattern convex surface on the hard roller is pressed in the soft roller gradually, some part of soft roller is the cavity of decorative pattern on the hard roller of filling gradually, and the soft roller body of roll is formed and the corresponding identical patterned roll of roller firmly.General each drafts is 0.01～0.05 millimeter.
Advantage of the present invention is:
1. working roll adopts a hard roller and a soft roller, but reduce hard roller wearing and tearing life-saving, though and the simple cost of soft roller rapid wear manufacturing is low, cladding damages can be cast into soft roller again on former steel core.
2. the manufacturing process of the working roll that is proposed need only utilize open-and-shut equipment tool just can process the floral designs of desired arbitrary shape, floral designs on the soft roller body of roll are soft roller and roller body of roll spreading formation under certain pressure firmly, so strict corresponding identical with the decorative pattern energy on the hard roller.Technical process is simple, grasps easily, and general materials processing factory also can make this working roll.
3. use the rolling diamond plate of this working roll phenomenons such as decorative pattern rolls seldom to occur, good product quality, yield rate height.
