Description
Technical field
The present invention relates to Roller Machining and recovery technique field, the multiple carving technology of especially a kind of figured plate working roller, use
Tofu pudding after roller surface abrasion is carved again.
Background technology
Diamond plate because its have the characteristics that it is attractive in appearance, anti-skidding, easy to clean, be widely used in building, machine-building, bridge,
The every field such as traffic, shipbuilding, decorative pattern panel products are mainly produced by hot continuous rolling process, i.e., are mainly in process of production
The figured plate working roller that Tofu pudding (Tofu pudding is also pattern groove) is carved with by roll surface (is also referred to as diamond plate work roll, pattern groove rolls
Roller) rolled, plate face metal flow is filled into Tofu pudding by applying roll-force effect in the operation of rolling.According to national standard
Illustrate in GB/T3277-1991 and professional standard YBT/4159-2007, at present the main style of decorative pattern panel products be rhombus, it is flat
Beans shape, circle beans shape and the combination class of shape four.
In the diamond plate operation of rolling, because working roll directly produces interaction between metal with being rolled, rolling
Figured plate working roller should bear very big dynamic pressure and bending stress in journey, bear the larger temperature shadow of amplitude of variation again
Ring, after certain amount of rolling, working roll roll surface can be worn, the parameter hair such as the groove depth of Tofu pudding, flute length, groove width, flute profile
Raw to change, the working roll that Tofu pudding produces after certain loss can not meet rolling demand, it is necessary to carry out two to the Tofu pudding on working roll
Secondary processing can be reused after repairing.
The secondary processing method of existing figured plate working roller, is mainly included the following steps that：Turning is carried out to working roll to add
Work, the original Tofu pudding turning of work roll surface is fallen；Working roll after turning is ground, makes the parameters of roller surface
Meet to require；Again Tofu pudding is scribed in roller surface using milling machine.Existing processing method is primarily present following shortcoming：First, enter
Capable turnery processing amount is big, and time-consuming, high processing costs；Second, substantially reduce the service life of figured plate working roller, decorative pattern
Amount of rolling of plate working roll is 800 tons or so, and after rolling 3 times, the Tofu pudding on working roll can not be inconsistent because of deformation
Close and require, it is necessary to carve roller again, traditional diamond-making technique needs original Tofu pudding whole turning is clean, the then weight after grinding machine is processed
Newly scribe, the waste of work roll diameter turning once is 6.5~7mm.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of figured plate working roller Tofu pudding multiple carving technology in situ, to solve
Existing figured plate working roller problem present in secondary processing process, Lathe quantity is reduced, shorten machining period, reduction is processed into
This, extends roll working life.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of figured plate working roller Tofu pudding multiple carving technology in situ, the technique comprise the following steps：
1) grinding, the figured plate working roller after Tofu pudding is worn, which is placed on roll grinder, carries out accurate grinding, makes flower
The roughness of card working roll roll surface meets that multiple carve requires；
2) at Tofu pudding multiple quarter in situ, first the Tofu pudding in one cutting direction is handled along the axial direction of working roll, is specifically
Multiple quarter is carried out after being identified successively to original Tofu pudding on cutting direction by image recognition technology, further along roll axially to it
Original Tofu pudding in its cutting direction carries out multiple quarter；
3) forming processes, the figured plate working roller after multiple quarter is handled, makes surface roughness meet to require.
Technical solution of the present invention further improvement is that：In the step 1) stock removal of grinding be 0.02~
0.05mm, the pattern groove roll surface roughness Ra after grinding are 0.16~0.04 μm.
Technical solution of the present invention further improvement is that：Tofu pudding multiple carve in situ in the step 2) includes following step
Suddenly：
2-1) IMAQ, roller surface is axially divided into several image acquisition regions along working roll, used
Image capture device, the image of each image acquisition region is acquired successively；
2-2) image recognition, the image collected is handled, identify position and the shape of original Tofu pudding in image
Shape；
2-3) image rectification, according to the specification requirement at multiple quarter, original Tofu pudding is corrected on image, formation conforms to
The Tofu pudding image asked；
2-4) icking tool is positioned, and according to the Tofu pudding image after correction, milling head is positioned；
2-5) cutting, Tofu pudding is scribed again according to the specification requirement at multiple quarter.
Technical solution of the present invention further improvement is that：The step 2-1) in each image acquisition region at least
Include a complete Tofu pudding.
Technical solution of the present invention further improvement is that：The step 2-2) in the long axis of Tofu pudding in image and short
Axis is identified, and position and the shape of original Tofu pudding are determined according to long axis and minor axis.
Technical solution of the present invention further improvement is that：The step 2-3) in image rectification be according to the rule carved again
Lattice requirement, is corrected on the long axis and minor axis of original Tofu pudding in image, meets the specification requirement that Tofu pudding is carved again.
Technical solution of the present invention further improvement is that：The technique is applied to rhombus Tofu pudding, lablab shape Tofu pudding, circle beans
Shape Tofu pudding, the original position of combination shape Tofu pudding are carved again.
By adopting the above-described technical solution, the technological progress that the present invention obtains is：
A kind of multiple carving technology of decorative pattern grooved roller of the present invention, technical process is easy to grasp, easy to operate, automaticity
Height, Lathe quantity can be reduced, save the non-renewable precious metal such as substantial amounts of Cr, Ni, Mo, V, shorten machining period, reduced
Processing cost, extend roll working life, there is preferable economic benefit and social benefit.
The present invention carries out accurate image recognition and image rectification using image recognition technology to original Tofu pudding, can be in original
Have and multiple quarter is carried out on the basis of Tofu pudding, without all original Tofu puddings are removed, considerably reduce Lathe quantity, extend and roll
The service life of roller.Original pattern groove is accurately positioned present invention employs image recognition technology, multiple quarter can be ensured
The accuracy of position, decorative pattern groove location produces deviation during preventing multiple carve, and makes the roll quality after multiple carve meet to require.
The secondary processing method of working roll of the prior art, every time will be by the diametric(al) of working roll after processing
The surface of working roll is ground away into 6.5~7mm, this process at least needs to spend 36 hours, and work roll diameter can also produce greatly
The reduction of amplitude, a secondary operation is carried out, at least need to spend 2.4 ten thousand yuan of expenses, a new working roll is generally carried out 6 times
Production requirement cannot be met after secondary operation.
And the Tofu pudding carving technology in situ multiple of the present invention, when processing every time, the surface of working roll need to only grind away to 0.02~
0.05mm, this process need only to spend 8 hours, it is only necessary to spend 0.6 ten thousand yuan of expenses, a new working roll generally carries out 30
Secondary multiple carve can also be normally carried out using, and greatly extend the service life of working roll roller.
