Definitions
- the invention relates to the technical field of rounding of a coiling machine, in particular to a rounding process of a numerically controlled rounding machine.
- the rounding machine is generally composed of two lower rolls of equal diameter and parallel to each other and an upper roll which is movable between the lower rolls and parallel to the lower rolls, and is driven by the upper roll and the lower rolls.
- the rounding of the non-positive cylindrical workpiece is achieved.
- the distance between the upper roller and the center line of the two lower rollers is adjusted, and the upper roller is pressed down to adapt to the rounding of the cylinder workpieces of various specifications.
- the parameter data and process methods of the upper and lower roller movements are determined only by the experience of the technician. For different diameters, different materials, different cylinder wall thicknesses and different roundness requirements, the traditional three-roll bending machine and process method are used for rounding, which cannot guarantee product quality requirements, production efficiency requirements and automated assembly requirements. .
- the object of the present invention is to provide a rounding process for a numerically controlled rounding machine, in which a high-precision sensor is mounted on the numerically controlled rounding machine for accurately measuring the position of the upper roller of the rounding machine, and the sensor is connected to the PLC controller.
- the upper roller lifting and lowering mechanism can adopt the ball screw pair. If hydraulic transmission is adopted, the system should have automatic leveling function; the PLC controller built-in program to calculate each rounding parameter, feedback In the running state, each process action command is transmitted, and the numerical control method is adopted to perform high-precision rounding of the cylindrical workpiece. It is easy to operate.
- the program can accurately calculate and control the various steps of the rounding machine in real time. Thereby ensuring accurate rounding, improving work efficiency, reducing labor intensity, improving product qualification rate, and reducing cost.
- the rounding process steps of the numerical control rounding machine are as follows - First: The total rolling amount of the upper roller is set and divided into n intervals, each interval is called Rounding passes, n passes in n intervals;
- the amount of depression for each pass is set to X.
- the X can be set to equal value as needed, or it can be unequal. If the value is not equal, the amount of depression X in each interval is set separately.
- Each pass sets the number of times the lower roller drives forward and reverse, and the lower roller rotates forward and reverse once for one cycle, which is beneficial to the rounding forming, eliminating the deformation stress and improving the correction accuracy; "When, it means that the lower roller is driven to rotate in one direction. During the rounding process, the number of cycles of the last pass should be greater than 1;
- the PLC controller commands the non-positive cylindrical workpiece according to the n-pass, the X-pressing amount and the cycle number of the lower roller drive, and the upper roller pressing and the lower roller driving rotation;
- the pass n can be set to 1, that is, the upper roll is pressed or the upper roll is raised to steplessly progressive. And at a constant speed, the correction of the workpiece is performed;
- the PLC controller instructs the variable frequency motor to accelerate, and drives the upper roller to rise rapidly to the upper position of the upper roller/z. Position, open the inside of the rounding machine
- the overturning device which exits the cylindrical workpiece, realizes high-precision NC automatic rounding of non-positive cylindrical workpieces.
- the built-in program of the PLC controller will calculate the relevant data of each action command according to the known parameters, so as to finally determine the maximum reduction of the correction, and realize the scientific and reasonable correction of the cylindrical workpiece. circle.
- the PLC controller's built-in program calculates the relevant data calculation methods as follows:
- the correction maximum reduction is the value of the reduction of the upper roll from the upper position of the upper position, the deformation of the cylinder, and the curvature after the rebound is equal to the reduction of the curvature of the perfect circle. Correcting the maximum reduction is a very important and critical value. If the value is too small, the correction will not be in place. If the value is too large, it will be overcorrected. Both cases will affect the accuracy of the rounding.
- the invention adopts a PLC controller, and the built-in program of the PLC controller calculates each rounding parameter, feeds back the running state, and transmits each process action command to achieve high-precision rounding of the cylindrical workpiece by the numerical control mode. It has easy operation.
- the program can accurately calculate the correction amount in real time, generate relevant data, and control the various steps of the rounding machine to ensure accurate rounding. , improve work efficiency, reduce labor intensity, improve product qualification rate, and reduce the cost of production.
- Figure 1 is a schematic view of the rounding principle of the present invention
- the amount of depression for each pass is set to x.
- the X can be set to equal value as needed, or it can be unequal. If the value is not equal, the amount of depression X in each interval is set separately.
- Each pass sets the number of times the lower roller 2 drives the forward rotation and the reverse rotation, and the lower roller 2 rotates forward and reverse once for one cycle, which is beneficial to the rounding forming, eliminates the deformation stress, and improves the correction accuracy;
- "Space” means that the lower roller 2 is driven to rotate in one direction.
- the number of cycles of the last pass should be greater than 1;

- the upper roller 1 is pressed down and the lower roller 2 is driven to rotate;
- the PLC controller issues a program transmission command, the upper roller 1 is no longer pressed, and the upper roller 1 will be set to the original n times. In the opposite direction, the rounding is performed while the applied pressure is unloaded.
- the pass n can be set to 1, that is, the upper roller 1 is pressed down or the upper roller 1 rises to stepless gradual and uniform speed, and the correction of the cylindrical workpiece 3 is carried out; seventh: after the upper roller rises to the non-correction interval, the PLC controller instructs the variable frequency motor to accelerate, and drives the upper roller to rise rapidly to the upper position of the upper roller. Position, open the overturning device in the rounding machine, exit the cylindrical workpiece, and realize the high-precision NC automatic rounding of the non-positive cylindrical workpiece.
