Problems solved by technology

[0002] The existing numerical control machining method for roll passes completes the turning processing of all roll bodies and passes at one time, and has the following problems: 1. Completes the turning processing of all roll bodies and passes at one time. Influenced by the durability of the tool, the tool must be replaced during the machining process; after each tool change, the tool needs to be re-set, resulting in the presence of knives on the machined surface of the roll, which affects the surface quality of the pass and the position accuracy of the pass. Improve the precision, it is difficult to ensure the processing quality of the roll; the processing efficiency is low, the durability of the tool and the rigidity of the machine tool are high; the program is complicated, the operator’s programming level is high, and errors are prone to occur

Embodiment 1

[0014]The numerical control processing method of the roll slitting pass of the present invention is specifically as follows:

[0015]The first step is to group the units. The rolls to be processed are grouped according to the roll pass, and they are divided into several processing units, that is, a group of passes used at the same time during rolling is regarded as a processing unit, and only one unit is processed at a time , After completing one unit, proceed to the next unit processing; until all processing is completed;

[0016]The second step is the unit size programming. When programming, each processing unit is programmed with a separate processing flow; based on the roll transmission end, a turning program is programmed for the outer circle of the roll body, and the outer circle is processed to the size required by the icon;

[0017]The third step is hole type processing. According to the processing technology requirements, the processes and tools of each processing unit are respectiv...

Embodiment 2

[0020]Such asfigure 1 withfigure 2The specific numerical control processing method of a certain rebar K1 roll shown in the following:

[0021]The roll has a total of 24 passes, which are rolled by four slits, and used in 6 groups, each with 4 passes; the first group is the 1, 7, 13, and 19 holes; the second group is the 2, 8 and 14 , 20 holes; the third group is holes 3, 9, 15, and 21; the fourth group is holes 4, 10, 16, and 22; the fifth group is holes 5, 11, 17, and 23; the sixth group is holes No. 6, 12, 18, and 24 holes;

[0022]When processing, take the transmission end as the benchmark, compile a turning program for the outer circle of the roll body and process it to the size required by the icon; compile the pass pattern used in the simultaneous rolling in production into one processing unit, such as 1, 7, 13, 19 hole types are compiled into 1 processing unit; it is divided into 6 processing units, and the program of each processing unit is compiled separately. (The hole size of e...

Abstract

The invention discloses a numerical control machining method for a roll slitting pass. The method specifically comprises the following steps of 1, unit grouping; 2, unit size programming; and 3, passmachining. The numerical control machining method for the roll slitting pass is a machining method designed for roll machining and the actual use condition of a roll. According to the method, one-timemachining of the roll pass is decomposed into a plurality of machining units, only one unit is machined each time, high-quality machining of the roll is achieved, and the machining problems that theroll machining surface quality is poor, and the position precision is unqualified are solved. According to the method, a complex comprehensive program is decomposed into a plurality of simple programs, programming is simple, and operation is convenient; repeated loading is not needed during pass machining, the turning time is greatly saved, the machining efficiency is improved, and tool consumption is reduced; the surface quality and the position precision of the roll pass can be effectively ensured; and meanwhile the requirements of pass machining for the tool and machine tool performance arereduced.

Description

Technical field[0001]The invention relates to a method for processing a roll pass, in particular to a numerical control processing method for slitting a roll of a roll, and belongs to the technical field of roll pass processing.Background technique[0002]The existing CNC machining method for roll passes completes the turning of all roll bodies and passes at one time. There are the following problems: 1. Complete turning of all rolls and passes at one time. During the machining process, the continuous turning time is longer and suffers The tool durability is affected, and the tool must be replaced during the machining process; the tool needs to be re-aligned after each tool change, resulting in the presence of knives on the surface of the roll, which affects the surface quality of the pass and the accuracy of the pass position. To improve the accuracy, it is difficult to ensure the processing quality of the roll; the processing efficiency is low, the durability of the tool and the rig...
