[0160] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0161] Embodiment 1

[0162] In view of the defects existing in the existing control technology of double-end slitting and grooving machines, based on the rich practical experience and professional knowledge in the design and manufacture of this field for many years, and in cooperation with the application of theory, the applicant actively conducts research and innovation, hoping to create a technology that can solve the defects in the existing technology, making the control technology of double-end slitting and grooving machines more practical. After continuous research, design, and repeated sample making and improvement, the present invention with practical value has finally been created.

[0163] In the embodiment of the present invention, the controlled object is a double-end slitting and grooving machine, which includes a fixed end, a mobile end, and an opening and closing mechanism for automatically opening or closing the mobile end and the fixed end; the structures of the fixed end and the mobile end are different; the mobile end includes a machine tool, a conveying mechanism installed on the machine tool, and a feeding mechanism, an upper scribing saw mechanism, a lower grooving saw 1 mechanism, a lower grooving saw 2 mechanism, a flying saw mechanism, a lower underlining saw mechanism, a splitting saw mechanism, and a pressing beam mechanism arranged in sequence along the side of the conveying mechanism; the fixed end includes a machine tool, a conveying mechanism installed on the machine tool, and a feeding mechanism and a pressing beam mechanism arranged in sequence along the side of the conveying mechanism.

[0164] Please refer to Figure 1 , the embodiment of the present invention provides a control system for a double-end slitting and grooving machine, and the system includes a human-machine interaction unit 1, a central control unit 2, a feeding control unit 3, an upper scribing saw control unit 4, a lower grooving saw 1 control unit 5, a lower grooving saw 2 control unit 6, a flying saw control unit 7, a lower underlining saw control unit 8, a splitting saw control unit 9, a pressing beam control unit 10, a conveying control unit 11, and an opening and closing control unit 12;

[0165] The human-machine interaction unit 1 is connected to the central control unit 2;

[0166] The central control unit 2 is respectively connected to the feeding control unit 3, the upper scribing saw control unit 4, the lower grooving saw 1 control unit 5, the lower grooving saw 2 control unit 6, the flying saw control unit 7, the lower underlining saw control unit 8, the splitting saw control unit 9, the pressing beam control unit 10, the conveying control unit 11, and the opening and closing control unit 12.

[0167] It should be noted that in order to realize the automatic control of the double-end slitting and grooving machine, in this embodiment, a control unit is correspondingly configured for each mechanism in the double-end slitting and grooving machine, and it is designed to make these control units cooperate with each other, that is, to control each mechanism to complete each process respectively, so as to realize the automatic operation of the double-end slitting and grooving machine.

[0168] In this embodiment, the human-machine interaction unit 1, that is, the upper computer, can be an industrial PC. As Figure 2As shown in the figure, the system takes bus control technology as the core, adopts a control method combining communication and I / O points, is convenient for wiring, has a fast response speed, and has three types of communication controls in the system: Ethernet, CANopen bus, and RS485 communication interface. Ethernet communication is used between the human-machine exchange unit 1 and each central control unit 2, with a high communication rate. Data is exchanged between each central control unit 2 through an internal network. CANopen bus communication is used for communication between the central control unit 2 and the servo drivers of each component.

[0169] The control position signal of the device is provided by a rotary encoder on the driving transmission shaft, replacing the traditional travel switch control, improving the stability of the device, and the system parameters can be changed through the host computer, facilitating the adjustment of the action position of the components.

[0170] In this embodiment, the central control unit 2 includes an industrial switch 201, a fixed-end programmable controller 202, and a mobile-end programmable controller 203;

[0171] The human-machine exchange unit 1 is communicatively connected to the industrial switch 201;

[0172] The industrial switch 201 is communicatively connected to the fixed-end programmable controller 202 and the mobile-end programmable controller 203 respectively.

[0173] Please refer to Figure 3 , in this embodiment, the feeding control unit 3 includes a fixed-end feeding component 301 and a mobile-end feeding component 302;

[0174] The fixed-end feeding component 301 includes an auxiliary upper pressure wheel cylinder 3011, an auxiliary upper pressure wheel solenoid valve 3012, an auxiliary upper pressure wheel motor 3013, an auxiliary upper pressure wheel frequency converter 3014, a feeding baffle cylinder 3015, a feeding baffle solenoid valve 3016, and a baffle induction switch 3017;

[0175] The auxiliary upper pressure wheel solenoid valve 3012, the auxiliary upper pressure wheel frequency converter 3014, the feeding baffle solenoid valve 3016, and the baffle induction switch 3017 are respectively connected to the central control unit 2 through an I / O module;

[0176] The auxiliary upper pressure wheel frequency converter 3014 is also communicatively connected to the central control unit 2 through an RS485 communication interface;

[0177] The auxiliary upper pressure wheel motor 3013 is connected to the auxiliary upper pressure wheel frequency converter 3014;

[0178] It should be noted that the auxiliary upper pressing wheel component is the default selection in the program. After the device is powered on, the solenoid valve 3012 of the auxiliary upper pressing wheel is automatically energized, the cylinder 3011 of the auxiliary upper pressing wheel extends downward to press, and the starting method of the frequency converter 3014 of the auxiliary upper pressing wheel is the same as that of the conveying motor, and the linear speed is the same as that of the conveying motor. Due to different reduction ratios of each driving motor and different sizes of driving wheels, there are different parameters in the system corresponding to different frequencies to achieve the same linear speed. The relevant data is transmitted into the frequency converter 3014 of the auxiliary upper pressing wheel through RS485 serial communication. After the device is started, the device synchronously sends the workpiece into the slitter smoothly.

[0179] The feeding baffle controls the distance between workpieces, and this distance can be set according to needs in the parameters of the host computer.

[0180] The mobile feeding component 302 includes a side push cylinder 3021, a side push servo motor 3022, an ultra-wide induction switch 3023, an ultra-thick induction switch 3024 and a side push servo driver 3025;

[0181] The side push cylinder 3021, the ultra-wide induction switch 3023 and the ultra-thick induction switch 3024 are respectively connected to the central control unit 2 through an I / O module;

[0182] The side push servo driver 3025 is communicatively connected to the central control unit 2 through a CANopen bus;

[0183] The side push servo motor 3022 is connected to the side push servo driver 3025.

[0184] It should be noted that this device can prevent the error of the plate size and damage to the machine.

[0185] The position confirmation of the side push mechanism in the feeding mechanism of the mobile end is as follows: as Figure 4 shown, the system automatically calculates the position data of the side push servo motor 3022 according to the size of the plate and the position of the opening and closing mechanism, and then moves to the required position. The side push cylinder 3021 is used as a supplement to the side push position. The side push cylinder 3021 works all the time, providing an adjustable buffer side push pressure for the side push to avoid hard contact between the side push surface and the side surface of the workpiece.

[0186] This side push device can make the side push close to the side surface of the workpiece, laterally position the moving workpiece, and smoothly send the workpiece into the slitter;

[0187] In the manual working mode and the program stop state, the side push servo motor 3022 can be moved in a jogging manner on the host computer.

[0188] Please refer to Figure 5In this embodiment, the upper scribing saw control unit 4 includes an upper scribing saw mechanism tool motor 401, an upper scribing saw mechanism tool inverter 402, an upper scribing saw mechanism X-axis servo motor 403, an upper scribing saw mechanism Z-axis servo motor 404, an upper scribing saw mechanism X-axis servo driver 405, an upper scribing saw mechanism Z-axis servo driver 406, an upper limit position sensing switch 407, a lower limit position sensing switch 408, an upper limit position sensing switch 409 and a lower limit position sensing switch 410;

[0189] The upper marking saw mechanism tool frequency converter 402, upper limit position sensing switch 407, lower limit position sensing switch 408, upper limit position sensing switch 409 and lower limit position sensing switch 410 are respectively connected to the central control unit 2 through I / O modules;

[0190] The upper scribing saw mechanism tool motor 401 is connected to the upper scribing saw mechanism tool frequency converter 402;

[0191] The upper scribing saw mechanism X-axis servo driver 405 and the upper scribing saw mechanism Z-axis servo driver 406 are respectively connected to the central control unit 2 through a CANopen bus;

[0192] The upper scribing saw mechanism X-axis servo motor 403 is connected to the upper scribing saw mechanism X-axis servo driver 405;

[0193] The upper scribing saw mechanism Z-axis servo motor 404 is connected to the upper scribing saw mechanism Z-axis servo driver 406 .

[0194] It should be noted that the function of the upper scoring saw mechanism is to cut a groove with adjustable depth on the surface of the workpiece to prevent uneven cross-section when cutting.

[0195] The setting position of the X-axis servo motor 403 of the horizontal upper scribing saw mechanism is automatically consistent with the setting position of the X-axis servo motor of the splitting saw mechanism. The fine adjustment of the position of the X-axis servo motor 403 of the horizontal upper scribing saw mechanism can be compensated by its origin position error parameter. The actual working height of the Z-axis servo driver 406 of the vertical upper scribing saw mechanism is equal to the plate thickness minus the scribing depth (system parameter). The scribing depth can be set according to the process requirements, and the fine adjustment of the position can be compensated by its origin position error parameter.

[0196] In the manual working mode and the program stop state, the upper marking saw mechanism X-axis servo motor 403 in the horizontal direction or the upper marking saw mechanism Z-axis servo driver 406 in the vertical direction can be moved in a jog manner on the host computer.

[0197] After the program starts, the X-axis servo motor 403 of the upper scribing saw mechanism and the Z-axis servo motor 404 of the upper scribing saw mechanism automatically move to the required positions according to the program settings. The tool motor 401 of the upper scribing saw mechanism starts with a delay and rotates continuously to process the workpiece flowing through. When the component is not enabled, after the program starts, the Z-axis servo driver 406 of the upper scribing saw mechanism automatically retracts to an avoidance position.

[0198] The key points of safety control are as Figure 6 shown. The shaft of the tool motor 401 of the upper scribing saw mechanism passes through the perforation in the mobile end pressing beam. Since both the Z-axis of the upper scribing saw mechanism and the pressing beam are mechanisms that can move up and down, if the operation is improper, it will cause a collision between the two. This application has carefully designed an interlocking control method. In the machine adjustment state, when the up and down keys of the Z-axis servo of the upper scribing saw mechanism or the mobile end pressing beam are jogged, the Z-axis servo of the upper scribing saw mechanism and the motor of the mobile end pressing beam will rise or fall simultaneously. When one mechanism is jogged up and down, the other will also rise or fall in the same direction. In the non-machine adjustment state, after the program starts, the pressing beam mechanism will act first. After the position is reached, the Z-axis servo of the upper scribing saw mechanism will be triggered to start. When the mobile end pressing beam contacts the upper limit induction switch 407 or the lower limit induction switch 408 during the up and down movement, the Z-axis servo of the upper scribing saw mechanism will automatically follow the up and down movement. After the mobile end pressing beam is positioned, the Z-axis servo of the upper scribing saw mechanism starts again and rises or falls to the required position.

[0199] The upper extreme limit induction switch 409 and the lower extreme limit induction switch 410 are for extreme limit protection. Once these two extreme limit induction switches are touched, the actions of the Z-axis servo of the upper scribing mechanism and the mobile end pressing beam in this direction will stop, thus avoiding a collision between the two mechanisms.

[0200] Please refer to again Figure 5 In this embodiment, the control unit 5 of the lower grooving saw 1 includes a tool motor 501 of the lower grooving saw 1 mechanism, a tool frequency converter 502 of the lower grooving saw 1 mechanism, an X-axis servo motor 503 of the lower grooving saw 1 mechanism, a Z-axis servo motor 504 of the lower grooving saw 1 mechanism, an X-axis servo driver 505 of the lower grooving saw 1 mechanism, a Z-axis servo driver 506 of the lower grooving saw 1 mechanism, and an anti-collision limit induction switch 507;

[0201] The tool frequency converter 502 of the lower grooving saw 1 mechanism and the anti-collision limit induction switch 507 are respectively connected to the central control unit 2 through the I / O module;

[0202] The tool motor 501 of the lower grooving saw 1 mechanism is connected to the tool frequency converter 502 of the lower grooving saw 1 mechanism;

[0203] The X-axis servo driver 505 of the lower grooving saw 1 mechanism and the Z-axis servo driver 506 of the lower grooving saw 1 mechanism are respectively connected to the central control unit 2 through the CANopen bus for communication connection;

[0204] The X-axis servo motor 503 of the lower grooving saw 1 mechanism is connected to the X-axis servo driver 505 of the lower grooving saw 1 mechanism;

[0205] The Z-axis servo motor 504 of the lower grooving saw 1 mechanism is connected to the Z-axis servo driver 506 of the lower grooving saw 1 mechanism.

[0206] Please refer to Figure 7 , in this embodiment, the control unit 6 of the lower grooving saw 2 includes a tool motor 601 of the lower grooving saw 2 mechanism, a tool frequency converter 602 of the lower grooving saw 2 mechanism, an X-axis servo motor 603 of the lower grooving saw 2 mechanism, a Z-axis servo motor 604 of the lower grooving saw 2 mechanism, an X-axis servo driver 605 of the lower grooving saw 2 mechanism, and a Z-axis servo driver 606 of the lower grooving saw 2 mechanism;

[0207] The tool frequency converter 602 of the lower grooving saw 2 mechanism is connected to the central control unit 2 through an I / O module;

[0208] The tool motor 601 of the lower grooving saw 2 mechanism is connected to the tool frequency converter 602 of the lower grooving saw 2 mechanism;

[0209] The X-axis servo driver 605 of the lower grooving saw 2 mechanism and the Z-axis servo driver 606 of the lower grooving saw 2 mechanism are respectively connected to the central control unit 2 through a CANopen bus for communication;

[0210] The X-axis servo motor 603 of the lower grooving saw 2 mechanism is connected to the X-axis servo driver 605 of the lower grooving saw 2 mechanism;

[0211] The Z-axis servo motor 604 of the lower grooving saw 2 mechanism is connected to the Z-axis servo driver 606 of the lower grooving saw 2 mechanism.

[0212] It should be noted that the structures of the control unit 5 of the lower grooving saw 1 and the control unit 6 of the lower grooving saw 2 are almost the same. Their functions are as follows: the control unit 5 of the lower grooving saw 1 grooves the moving side on the bottom surface of the workpiece according to process requirements. The control unit 6 of the lower grooving saw 2 grooves the fixed side on the bottom surface of the workpiece according to process requirements.

[0213] The X-axis servo motor 603 of the lower grooving saw 2 mechanism in the horizontal direction controls the groove edge distance. The data source can be set by the system or sent by the master control data. The fine adjustment of the position of the X-axis servo motor 603 of the lower grooving saw 2 mechanism in the horizontal direction can be compensated by its origin position error parameter. The Z-axis servo motor 604 of the lower grooving saw 2 mechanism in the up and down direction controls the grooving depth. The data source can be set by the system or sent by the master control data. The fine adjustment of the position of the Z-axis servo motor 604 of the lower grooving saw 2 mechanism can be compensated by its origin position error parameter.

[0214] In the manual mode and program stop state, the X-axis servo motor 603 of the lower grooving saw 2 mechanism in the horizontal direction or the Z-axis servo motor 604 of the lower grooving saw 2 mechanism in the vertical direction can be moved in a jogging manner on the host computer.

[0215] After the program is started, the X-axis servo motor 503 of the lower grooving saw 1 mechanism and the Z-axis servo motor 504 of the lower grooving saw 1 mechanism automatically move to the required positions according to the program settings. The tool motor of the lower grooving saw 1 mechanism starts with a time delay and rotates continuously to process the workpiece flowing through. If the component is not enabled, the Z-axis servo motor 504 of the lower grooving saw 1 mechanism automatically retracts to an avoidance position.

[0216] The key points of safety control are as Figure 8 , the upper scribing saw mechanism and the lower grooving saw 1 mechanism are on the same column. When the Z-axes of the two mechanisms move up and down, if the data settings are improper, there will be a risk of collision between the tools during the operation of the two mechanisms, which will cause damage to the components. The present application has carefully designed a control interlock method.

[0217] 1) Set a soft limit safety distance in the system for soft limit protection. When the difference between the set positions of the two mechanisms is less than the limit safety distance, the system will prompt an alarm and cannot be started. Or when the difference between the actual positions of the two mechanisms is less than the limit safety distance, the system will prompt an alarm and stop the machine.

[0218] 2) Set an anti-collision limit induction switch 507 between the two mechanisms. This switch will not be touched during normal operation, but when the position data of the mechanism is abnormal and touches this anti-collision limit induction switch 50, the system will immediately alarm and stop the machine, and at the same time stop the rotation of the tool.

[0219] Please refer to again Figure 7 , in this embodiment, the flying saw control unit 7 includes a flying saw mechanism tool motor 701, a flying saw mechanism tool frequency converter 702, a flying saw mechanism X-axis servo motor 703, a flying saw mechanism Z-axis servo motor 704, a flying saw mechanism X-axis servo driver 705, a flying saw mechanism Z-axis servo driver 706, a flying saw mechanism counterweight solenoid valve 707 and a flying saw mechanism counterweight cylinder 708;

[0220] The flying saw mechanism tool frequency converter 702 and the flying saw mechanism counterweight solenoid valve 707 are respectively connected to the central control unit 2 through the I / O module;

[0221] The flying saw mechanism tool motor 701 is connected to the flying saw mechanism tool frequency converter 702;

[0222] The flying saw mechanism counterweight cylinder 706 is connected to the flying saw mechanism counterweight solenoid valve 707;

[0223] The X-axis servo driver 705 of the jumping saw mechanism and the Z-axis servo driver 706 of the jumping saw mechanism are respectively connected to the central control unit 2 via CANopen bus for communication;

[0224] The jump saw mechanism X-axis servo motor 703 is connected to the jump saw mechanism X-axis servo driver 705;

[0225] The jump saw mechanism Z-axis servo motor 704 is connected to the jump saw mechanism Z-axis servo driver 706 .

[0226] It should be noted that the function of the jump saw mechanism is to saw and cut the tail of the workpiece from bottom to top to prevent the tail edge banding from being torn when the workpiece is cut open.

[0227] The setting position of the X-axis servo motor 703 of the horizontal jump saw mechanism is automatically consistent with the setting position of the X-axis servo motor of the split saw mechanism. The fine adjustment of the position of the X-axis servo motor 703 of the horizontal jump saw mechanism can be compensated by its origin position error parameter. The actual working height of the Z-axis servo motor 704 of the vertical jump saw mechanism is equal to the plate thickness plus the rise height (system parameter). The rise height can be set according to the process requirements, and the fine adjustment of the position can be compensated by its origin position error parameter.

[0228] The counterweight of the jumping saw mechanism is as follows Figure 9 As shown, the total mass of the jumping saw mechanism is heavy. In order to solve the influence of the gravity caused by its own weight when it descends quickly, the present application adds a counterweight device. When the Z-axis servo motor 704 of the jumping saw mechanism is in place, the counterweight solenoid valve 707 of the jumping saw mechanism is powered off, and the pressure in the cylinder makes the cylinder in a free state without air pressure. When the Z-axis servo motor 704 of the jumping saw mechanism is in place, the counterweight solenoid valve 707 of the jumping saw mechanism is energized, and the counterweight cylinder 706 of the jumping saw mechanism is pressurized, and the cylinder is in an extended state. When the Z-axis servo motor 704 of the jumping saw mechanism descends, the thrust generated by the cylinder extending upward can overcome part of the deadweight of the jumping saw mechanism. Make the mechanism descend smoothly and quickly. When the mechanism is in place, the counterweight solenoid valve 707 of the jumping saw mechanism is powered off. Repeat the next action.

[0229] In the manual working mode and the program stop state, the X-axis servo motor 703 of the horizontal jumping saw mechanism or the Z-axis servo motor 704 of the vertical jumping saw mechanism can be moved in a jog manner on the host computer.

[0230] The jump saw mechanism processes the tail of the workpiece. The starting position of the up and down movements is set in the system. Through the rotary encoder, the system automatically calculates the running position of the plate. When the tail of the plate reaches the set position (jump saw action parameter), the jump saw mechanism Z-axis servo motor 704 starts and the jump saw mechanism rises. When the tool leaves the tail of the plate, the action ends.

[0231] After the program is started, the X-axis servo motor 703 of the jump saw mechanism and the Z-axis servo motor 704 of the jump saw mechanism automatically move to the required position according to the program settings, and the tool motor is delayed to start and rotate continuously to process the workpiece passing through.

[0232] Please refer to Figure 10 In this embodiment, the underlining saw control unit 8 includes an underlining saw mechanism tool motor 801, an underlining saw mechanism tool inverter 802, an underlining saw mechanism X-axis servo motor 803, an underlining saw mechanism Z-axis servo motor 804, an underlining saw mechanism X-axis servo driver 805, and an underlining saw mechanism Z-axis servo driver 806;

[0233] The underlining saw mechanism tool frequency converter 802 is connected to the central control unit 2 via an I / O module;

[0234] The underline saw mechanism tool motor 801 is connected to the underline saw mechanism tool frequency converter 802;

[0235] The underline saw mechanism X-axis servo driver 805 and the underline saw mechanism Z-axis servo driver 806 are respectively connected to the central control unit 2 through a CANopen bus;

[0236] The underline saw mechanism X-axis servo motor 803 is connected to the underline saw mechanism X-axis servo driver 805;

[0237] The Z-axis servo motor 804 of the underline saw mechanism is connected to the Z-axis servo driver 806 of the underline saw mechanism.

[0238] It should be noted that the function of the down-scratching saw mechanism is to cut a groove with adjustable depth on the bottom surface of the workpiece to prevent uneven cross-section when cutting.

[0239] The set position of the X-axis servo motor 803 of the horizontal underlining saw mechanism is automatically consistent with the set position of the X-axis servo motor of the cutting saw mechanism. Fine adjustments in the position of the X-axis servo motor 803 of the horizontal underlining saw mechanism can be compensated by its origin position error parameters. The Z-axis servo motor 804 of the vertical underlining saw mechanism controls the working depth of the underlining and is set according to the process requirements. Fine adjustments in the position can be compensated by its origin position error parameters.

[0240] In manual mode and program stop state, the X-axis servo motor 803 of the horizontal underline saw mechanism or the Z-axis servo motor 804 of the vertical underline saw mechanism can be moved in a jog manner on the host computer.

[0241] After the program starts, the X-axis servo motor 803 of the underlined saw mechanism and the Z-axis servo motor 804 of the underlined saw mechanism are servo-controlled and automatically move to the required position according to the program settings. The tool motor starts with a delay and rotates continuously to process the workpiece flowing through. If the component is not enabled, after the program starts, the Z-axis servo motor 804 of the underlined saw mechanism automatically retracts to an avoidance position.

[0242] Please refer to again Figure 10 , in this embodiment, the cross-cut saw control unit 9 includes a cross-cut saw mechanism tool motor 901, a cross-cut saw mechanism tool frequency converter 902, a cross-cut saw mechanism X-axis servo motor 903, a cross-cut saw mechanism Z-axis servo motor 904, a cross-cut saw mechanism X-axis servo driver 905, and a cross-cut saw mechanism Z-axis servo driver 906;

[0243] The cross-cut saw mechanism tool frequency converter 902 is connected to the central control unit 2 through an I / O module;

[0244] The cross-cut saw mechanism tool motor 901 is connected to the cross-cut saw mechanism tool frequency converter 902;

[0245] The cross-cut saw mechanism X-axis servo driver 905 and the cross-cut saw mechanism Z-axis servo driver 906 are respectively communicatively connected to the central control unit 2 through a CANopen bus;

[0246] The cross-cut saw mechanism X-axis servo motor 903 is connected to the cross-cut saw mechanism X-axis servo driver 905;

[0247] The cross-cut saw mechanism Z-axis servo motor 904 is connected to the cross-cut saw mechanism Z-axis servo driver 906.

[0248] It should be noted that the function of the cross-cut saw mechanism is to cut the workpiece in half from the middle, dividing the workpiece into two parts.

[0249] The set position system of the cross-cut saw mechanism X-axis servo motor 90 in the horizontal direction is set according to the position of the cross-cut mechanism. Fine adjustment can be compensated by its origin position error parameter. The setting of this position is related to the X-axis servo motor 403 of the upper scribing saw mechanism, the X-axis servo motor 503 of the lower grooving saw 1 mechanism, the X-axis servo motor 603 of the lower grooving saw 2 mechanism, the X-axis servo motor 703 of the jump saw mechanism, the X-axis servo motor 803 of the underlined saw mechanism, and the position of the opening and closing mechanism. Changes in the set data of the horizontal direction X-axis of the cross-cut saw will cause automatic correction of the positions of other mechanisms, so as to achieve the purpose of cutting the workpiece in half from the middle.

[0250] The actual working height of the cross-cut saw mechanism Z-axis servo motor 904 in the up and down direction is equal to the plate thickness plus the rising height (system parameter). The rising height can be set according to process requirements. Fine adjustment of the position can be compensated by its origin position error parameter.

[0251] In the manual mode and program stop state, the X-axis servo motor 90 of the cutting saw mechanism in the horizontal direction or the Z-axis servo motor 904 of the cutting saw mechanism in the up and down direction can be moved in a jogging manner on the host computer.

[0252] After the program is started, the X-axis servo motor 90 of the cutting saw mechanism and the Z-axis servo motor 904 of the cutting saw mechanism automatically move to the required positions according to the program settings. The tool motor starts with a time delay and rotates continuously to process the workpiece flowing through. If the component is not enabled, after the program is started, the Z-axis servo motor 904 of the cutting saw mechanism automatically retracts to the avoidance position.

[0258] The driving frequency converter 1101 and the auxiliary feeding frequency converter 1103 are respectively connected to the central control unit 2 through an I / O module and are respectively also communicatively connected to the central control unit 2 through an RS485 communication interface;
