C. polishing the roller surface and retaining the original embossed grain bean marks to obtain a scrapped pattern roller when the new embossed grain roller is normally used until the pattern bean is scrapped;
D. c, detecting the scrapped pattern roller before repeated bean carving, and performing the step E after the detection is qualified; if the product is unqualified, the product is directly scrapped;
E. clamping the scrapped pattern roller after being detected to be qualified on a numerical control machine tool, simultaneously ensuring that the same circumferential position as that of the step B is maintained on the roller surface, aligning the outer circle of the roller surface, carrying out pattern bean carving according to the parameters determined in the step B, and realizing repeated bean carving at the same position.
The technical scheme of the invention is further improved as follows: and B, the pattern bean carving parameters in the step are known parameters.
The technical scheme of the invention is further improved as follows: the total groove number n=n1×2, n1= (3.14×d)/L3 distributed in the forward and reverse 45 ° directions on the circumference of the roller, and n1 is the total groove number distributed in the forward 45 ° direction on the circumference of the roller.

d1, observing the roll surface at 360 degrees to confirm that the roll surface has no cracks and meat falling;
and D2, screening the working layer by adopting a bicrystal detection method, and confirming that no subsurface crack exists in the expansion process.

The technical scheme of the invention is further improved as follows: and B, clamping in the steps B and E adopts flat head clamping.
By adopting the technical scheme, the invention has the following technical progress:
when the depth of the pattern beans of the pattern roller reaches the scrapped depth, the invention does not need to grind the residual pattern beans and re-etch the beans, but carries out covering re-etch on the basis of original residual bean marks to regenerate the pattern beans, thereby avoiding excessive grinding and abnormal loss of the roller caused by the complete grinding of the pattern beans, reducing the workload of a grinding machine and saving the consumption of grinding wheels, water, electricity, manpower and the like.
Detailed Description
The invention is further illustrated by the following examples:
example 1
A. The patterned roll was chosen to have a roll number F70695 and a diameter d of 639.01mm, following the technical specifications: the diameter d of the newly engraved roller is more than or equal to 636mm, and the diameter of the newly engraved roller is 639.01mm according to the on-site actual roller;
B. the spacing of the equidirectional embossing grooves is selected to be L3=42 mm, the spacing of the equidirectional embossing grooves is 36-42 mm according to the drawing requirement, the spacing of the equidirectional embossing grooves is selected to be optimal in view of improving efficiency and saving cost, and programmed milling parameters are calculated as follows:
the diameter d of the roller is 639.11mm, the length L1=1830 mm of the roller surface, the processing length L2=1638 mm of the roller surface pattern, the spacing L3=42 mm of the equidirectional pattern grooves, the depth h=3.2 mm of the milling grooves, and the milling parameters are calculated as follows:
(1) Total groove number distributed in forward and reverse 45 degree direction on the circumference of roller:
n=n1×2
wherein n1= (3.14 d)/l3= (3.14× 639.01)/42≡48 (rows); then n=48×2=96 (rows).
(2) The included angle theta=360/48=7.5 degrees between the two groups of pattern grooves in the circumferential direction of 45 degrees and the center of the roller;
the included angle between the positive 45-degree pattern groove and the reverse 45-degree pattern groove and the center of the roller is 3.75 degrees.
(3) The axial roller surface is processed into a groove number n2 of 45 degrees in the forward direction and a groove number n2 'of 45 degrees in the reverse direction'
n2=(L2/42)+1=(1640/40)+1=42；n2’=41
Determining a pattern bean carving program of F70695 and finishing new carving of the pattern roller according to the parameters to obtain a new carved pattern roller, and simultaneously recording the clamping position of the new carved roller on a numerical control machine tool;
C. polishing the roller surface and keeping original bean marks when the newly engraved pattern roller is used until the depth of the normally scrapped beans is 2.3mm, wherein the diameter is 636.91mm;
D. detecting the scrapped pattern roller before repeated bean carving:
(1) Observing the roller surface for 360 degrees before repeated bean carving, wherein the roller surface is free from cracks and meat falling; the engraved beans on the surface of the patterned roll can be regarded as roll surface defects, and the potential safety hazard is large by means of detecting the roll surface defects such as interference surface waves and eddy current detection.
(2) Screening the working layer by adopting a 2MHz bicrystal detection method, wherein no sub-surface cracks in the expansion process are found; the proportion of the surface area of the pattern beans to the surface area of the pattern roller is far smaller than that of a normal roller surface, a square blank area surrounded by the pattern beans can accommodate a bicrystal probe, a working layer is screened by adopting a bicrystal detection method, subsurface cracks in extension are found in time, and the defects of surface wave and vortex detection are overcome.
E. Clamping the scrapped pattern roller after being qualified in detection on a numerical control machine tool, clamping and maintaining the same circumferential position as the last time through a flat head, positioning and maintaining the same circumferential position as the last time on the roller surface, performing tool setting on the outer circle of the roller surface, and performing pattern bean carving according to the parameters determined in the step B, so that repeated bean carving at the same position is realized.
By adopting the repeated bean carving method, the residual pattern beans are not required to be ground off and then re-carved, and the covered re-carved beans are used for regenerating the pattern beans on the basis of the original residual bean marks, so that excessive grinding and abnormal loss of the roller caused by the fact that the pattern beans are completely ground flat are avoided, and meanwhile, the workload of a grinding machine is reduced, and the consumption of grinding wheels, water, electricity, manpower and the like is saved.
