Abstract
The invention discloses a kind of three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning, it includes：According to the traditional method of indicating the pronunciation of a Chinese character direction during turning, cutter is rotated into 2 ° of turning at b points from initial position, at withdrawing 0.5mm to c points, continue to rotate 2 ° of traditional methods of indicating the pronunciation of a Chinese character at d points, at withdrawing 1mm to e points, continue 2 ° of traditional methods of indicating the pronunciation of a Chinese character of rotation at f points, at withdrawing 2mm to g points, playback to initial position, according to turning direction from initial position 120 ° of turning of rotation, turning goes out work surface to cutter.According to the step traditional method of indicating the pronunciation of a Chinese character method for turning that the present invention is provided, a ladder is first set up on collars, cutting force is gradually discharged, so as to ensure that roll edge is unlikely to the chipping because cutting force is excessive, turning can be carried out with maximum cutting force, cutting depth, cutting speed during turning, so as to improve the process of Roller Machining efficiency and yield rate.
Description
Technical field
The present invention relates to Roller Machining technical field, more particularly to a kind of three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning.
Background technology
In current Seamless steel tube industry, the processing of three rollers (determining tube reducing) frame, most of or dependence on import lathe, turning
Mono- handle of a knife of Shi Caiyong, 120 ° of lathe tools are mutually on handle of a knife equipped with three, need to be according to the size of pass, using tool setting gauge during open cell type
Adjust the length of cutter, to good knife after, determine several knives of car according to pass and processing capacity size, last knife compensation, during turning
Program and Lathe quantity lathe automatic running are input into NC machine tool operation panel, when Lathe quantity can automatic reverse more than 10mm lathes
The segment distance of feed one (the referred to as traditional method of indicating the pronunciation of a Chinese character), performs this program untill required size repeatedly, last chamfered edge detection it is qualified into
Product.Have the disadvantage：Firstly, since three can be because making tangent after three roll elder generation traditional methods of indicating the pronunciation of a Chinese character of knife turning simultaneously to factors such as knife precision deficiencies
Left at knife tool marks (traditional method of indicating the pronunciation of a Chinese character print) into connecing, cause unnecessary production to waste and (produce roll marks or cyan line to cause steel pipe after such as reaching the standard grade
Degrade and waste or loaded vehicle is not into causing to scrap)；Secondly, after part roll Reusability quenches through steel rolling, in roller surface
Metallographic structure in form harder carbide and roll is become hard and crisp, Unit cutting force reaches 3000MPa during due to turning, by force
Pass chipping phenomenon is serious during strong impact turning, in addition damage cutter cause body of roll loaded vehicle amount it is larger change the next pass of car not into
Work(is only scrapped needs tool changing tool of losing time, and brings very big problem, and cost higher to waste to normal production turning；Again
It is secondary, part roll again by steel rolling when, cooling water is hydraulic pressure is relatively low and during water shortage, roll flow harden phenomenon is serious, car
Pass chipping phenomenon is serious when cutting, and body of roll loaded vehicle amount is larger, changes that the next pass of car is unsuccessful only to be scrapped.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning.
The present invention provides a kind of three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning, and it includes：
According to the traditional method of indicating the pronunciation of a Chinese character direction during turning, cutter is rotated into 2 ° of turning at b points from initial position, withdrawing 0.5mm to c points
Place, at continuation 2 ° of traditional methods of indicating the pronunciation of a Chinese character of rotation to d points, at withdrawing 1mm to e points, at continuation 2 ° of traditional methods of indicating the pronunciation of a Chinese character of rotation to f points, at withdrawing 2mm to g points,
Playback to initial position, according to turning direction from initial position 120 ° of turning of rotation, turning goes out work surface to cutter.
The beneficial effects of the invention are as follows：According to the step traditional method of indicating the pronunciation of a Chinese character method for turning that the present invention is provided, first set up on collars
One ladder, cutting force is gradually discharged, so that ensure that roll edge is unlikely to the chipping because cutting force is excessive, can during turning
Turning is carried out with maximum cutting force, cutting depth, cutting speed, so that the technique side for improving Roller Machining efficiency and yield rate
Method.
Roller Machining is averagely taken by 180min/ sorties, is reduced to 150min/ sorties, and processing efficiency improves nearly 21%.
During smart car, it is zero that processing metapore rooved face better quality causes that the roll traditional method of indicating the pronunciation of a Chinese character prints phenomenon, and during rolled steel tube, lumber recovery improves near
0.1%.The problem of chipping when solving high-hardness roller pass machining.

Specific embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
In order to overcome three-roll rack in turning using a knife traditional method of indicating the pronunciation of a Chinese character, connect and left at knife tool marks (traditional method of indicating the pronunciation of a Chinese character print), pass
Chipping phenomenon seriously causes tube quality to degrade (produce cyan line and roll marks) and the serious problem of cost waste, and the present invention provides one
Three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning is planted, the technique can not only improve the turning yield rate of frame, can also improve steel
Pipe quality, is that company of Baogang reduces production cost, is that one kind operates effectively method.
The technical solution adopted for the present invention to solve the technical problems is：A ladder is first set up, cutting force is gradually released
Bleed off, so as to ensure that roll edge is unlikely to the chipping because cutting force is excessive, during turning with maximum cutting force, cutting depth, cut
Cutting speed carries out turning, so as to improve the process of Roller Machining efficiency and yield rate.
In a kind of specific embodiment, the invention provides a kind of three-roll rack step traditional method of indicating the pronunciation of a Chinese character method for turning.Please
