Description

Technical Field

[0001] The invention belongs to the technical field of numerical control bending machines, in particular to a follow-up material supporting device for a numerical control bending machine and a use method thereof. Background Art

[0002] The sheet metal bending machine (both CNC and ordinary bending machines can be used) requires manual assistance to lift the sheet in order to synchronously reach the preset angle. Asynchronous operation will lead to deviation in the sheet forming angle and even serious deformation of the sheet. The bending machine sets different downward strokes and speeds for different sheet thicknesses and formats, which will result in different lifting speeds. Large-format and thick plates require two or more people to lift them. It is difficult to coordinate consistency and synchronization, which will increase the workload a lot. The forward push and backward pull caused by lifting during the work process will affect the bending size accuracy. Secondly, aluminum plates or mirror plates may be scratched due to sliding on the lifting platform. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a CNC bending machine follow-up support device and a method of using the same, which can avoid the bending size accuracy being affected by the forward pushing and backward pulling caused by the lifting during the working process. Secondly, it can also avoid scratches on aluminum plates or mirror plates due to sliding on the working platform, thereby solving the problems mentioned in the above background technology.

[0004] The present invention provides the following technical solutions: The first aspect of the present invention is to provide a CNC bending machine follow-up support device, including a shell and a lifting mechanism, the lifting mechanism includes a working platform and a moving mechanism, the moving mechanism includes a servo motor and a plurality of moving arms, and the plurality of moving arms form a moving linkage body, and the moving mechanism screw rod is driven by the servo motor, thereby driving the moving linkage body to move, so that the moving linkage body drives the working platform to rotate around the zero point of the working platform.

[0005] The existing lifting is basically completed by dual motors and two motion mechanisms. However, the dual motors are not synchronized, which will cause the angle deviation of the sheet forming, resulting in forward pushing and backward pulling, which will affect the bending size accuracy. Secondly, the aluminum sheet or mirror sheet will be scratched due to sliding on the lifting platform.

[0006] There is one servo motor, and the motion mechanism also includes a motion mechanism housing. The motion mechanism housing includes two motion mechanism side panels arranged opposite to each other. The bottom of the two motion mechanism side panels is provided with a motion mechanism bottom plate connecting the two, and the motion mechanism bottom plate is tilted. In order to achieve the initial tilted position of the servo motor, a motion mechanism rear plate is also provided between the two motion mechanism side plates, and an opening is provided on the motion mechanism rear plate. The front and rear motion screw rods II pass through the aforementioned openings, and the front and rear motion screw rods I located below are synchronously driven by a gear belt. A rotating block is provided under the servo motor, and a rotating connecting block is fixedly provided in the motion mechanism housing. The rotating connecting block cooperates with the rotating block to realize the rotation of the servo motor around the center of the rotating connecting block. A moving block of a motion mechanism is sleeved on the screw rod, and an internal thread that cooperates with the screw rod of the motion mechanism is arranged in the moving block of the motion mechanism. The moving block of the motion mechanism is rotatably connected to the third motion arm, the third motion arm is rotatably connected to the side plate of the motion mechanism through the seventh point, and is rotatably connected to the second motion arm through the fourth point. The other end of the second motion arm is rotatably connected to the working platform through the third point, and the other end of the working platform is connected to the first motion arm through the first point, the other end of the first motion arm is connected to the fourth motion arm through the second point, and the other end of the fourth motion arm is rotatably connected to the side plate of the motion mechanism through the fifth point, and the middle of the fourth motion arm is rotatably connected to the second motion arm through the sixth point, so that the motion linkage body drives the working platform to rotate around the rotation zero point of the working platform.

[0007] The fifth point on the fourth moving arm and the seventh point on the third moving arm are not on the same vertical plane, and the housing is further provided with symmetrically arranged supporting members and moving members for movement.

[0008] The first point, the second point, the third point, the fourth point, the fifth point, the sixth point and the seventh point are the positions of the connection rotation points. The method of realizing the rotation connection is not limited. For example, the pin shaft rotates, and the position rotation of the corresponding point can be realized by the cooperation of the shaft and the hole, or the cooperation of the sleeve and the core, etc.

[0009] The seventh point on the third moving arm and the fifth point on the fourth moving arm are the moving fulcrums of the moving mechanism. Under the movement of the third moving arm, the other moving arms realize their own movements around the seventh point on the third moving arm and the fifth point on the fourth moving arm, so that the moving linkage body drives the working platform to rotate around the zero point of the working platform. Avoid the forward push and backward pull caused by the lifting during the working process to affect the bending size accuracy, and secondly, the aluminum plate or mirror plate will be scratched due to sliding on the lifting platform.

[0010] The moving part is a universal wheel, and the supporting part is an adjustable foot. More preferably, the universal wheel has a locking device, or the universal wheel and the fixed wheel are used in combination. Two universal wheels and two fixed wheels.

[0011] The adjustable foot includes a foot connection block connected to the shell, the foot connection block is provided with a socket, a limit pin cooperates with the socket, the foot is rotatably connected to the foot connection block through a foot connection arm, the socket is located outside the rotation point of the foot connection arm, when the foot plays a supporting role, the foot connection arm is inclined downward at an angle to the horizontal plane, and the limit pin is located above the foot connection arm, limiting the upward rotation of the foot connection arm.

[0012] There are four adjustable feet, which are foldable and lift-up feet. The front two are in a straight line shape extending on both sides, extending to the outside of the equipment, which can better stabilize the left and right swing amplitude of the machine. The back two feet are in an outward eight-shaped shape, with the left one slanted outward than the left, and the right one slanted outward than the right, and both extend to the outside of the equipment.

[0013] It also includes an adjustment mechanism, and a symmetrically arranged motion mechanism connecting arm is provided on the outer side of the motion mechanism shell. A through hole is provided on the motion mechanism connecting arm, and the forward and backward sliding optical axis passes through the through hole to connect the lifting mechanism and the inner shell. The inner shell is open at the upper end and is used for the up and down lifting movement of the motion mechanism.

[0014] An operation panel is provided on the inner front plate of the inner shell, a first through hole is provided on the inner rear plate of the inner shell, a forward and backward motion motor is provided on the inner wall of the inner rear plate at the corresponding position, and the forward and backward motion screw rod of the forward and backward motion motor passes through the first through hole. A through groove is also provided on the inner rear plate for arranging the up and down motion motor, the up and down motion screw rod and the first connecting block sleeved on the outside of the up and down motion screw rod to realize the up and down movement of the first connecting block.

[0015] The front and rear moving motor drives the front and rear moving screw rod, which is connected to the outer shell of the moving mechanism, so that the moving mechanism can slide forward and backward on the front and rear sliding optical axis; the up and down moving motor drives the up and down moving screw rod, which drives the sleeved first connecting block to move up and down, because the first connecting block is connected to the outer rear plate of the outer shell, so as to realize the overall up and down movement of the inner shell and the moving mechanism. The front and rear and up and down fine-tuning can be used to adapt to the bending machines of different manufacturers. The up and down fine-tuning uses an independent control system, which is separated from the servo motor and uses an independent control system to avoid mutual interference between circuits.

[0016] The through slot is an inverted T-slot, the up and down motion motor is located at the horizontal part of the T-slot, the side wall of the first connecting block is connected to the outer shell, and the inner rear plate and the outer rear plate of the outer shell are symmetrically provided with matching sliders and up and down motion rails at corresponding positions, and the other side of the slider is fixed to the inner rear plate.

[0017] Another preferred solution is that the outer shell is provided with two thread-adjustable support rods at the front, so as to have a fixed and stable distance between the outer shell and the bending machine.

[0018] The aforementioned method for using the CNC bending machine follow-up support device is as follows: (1) The bending machine is equipped with an external grating ruler to collect data; (2) Push the CNC bending machine follow-up support device close to the bending machine through the universal wheel, adjust the foot to the folding upper lift foot, pull out the limit pin, turn the folding upper lift foot down, insert the limit pin, the limit pin is located outside the rotation point of the foot, and there are two threaded support rods at the front end of the equipment. One end of the support rod is against the surface of the bending machine, so that there is a fixed and stable distance between it and the bending machine; (3) Place the plate to be processed on the working platform. According to the parameters and structures of the bending machines of different manufacturers, the working platform position of the CNC bending machine follow-up support equipment is fine-tuned up and down or forward and backward by adjusting the mechanism to adapt to the bending machines of different manufacturers; (4) When the upper die of the bending machine just contacts the plate, the CNC bending machine follow-up support device of the present invention can memorize this point as the action point according to the numerical value of the external grating ruler; (5) When in use, just enter the V-groove specifications and plate thickness of the bending machine on the equipment operation panel to lift synchronously; (6) When lifting, the servo motor starts to drive the motion mechanism screw to rotate. A motion mechanism moving block is provided on the outside of the motion mechanism screw. The motion mechanism moving block is connected to the third motion arm in rotation. The third motion arm and the first motion arm, the second motion arm, the third motion arm, the fourth motion arm and the working platform form a motion linkage body, so that the motion linkage body drives the working platform to rotate around the working platform zero point flip.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The motion mechanism uses a single-drive servo motor to drive the motion mechanism screw rod, and then drives several connected motion arms through the third motion arm, so that the motion linkage body drives the working platform to rotate around the rotation zero point of the working platform, thereby realizing the lifting of the working platform, avoiding the errors and failure rates of the multi-drive motor coordination in the lifting work, and also avoiding the forward pushing and backward pulling caused by the lifting during the working process, which affects the bending size accuracy. Secondly, there will also be problems such as scratches on aluminum plates or mirror plates due to sliding on the lifting platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Specific embodiment 1: Please refer to Figure 1-9 The first aspect of the present invention is to provide a CNC bending machine follow-up support device, including a shell and a lifting mechanism, the shell includes a moving mechanism shell 4 protected by the moving mechanism, an inner shell 2 and an outermost outer shell 1.

[0024] The motion mechanism housing 4 includes two relatively arranged motion mechanism side panels 401, a motion mechanism bottom panel 402 and a motion mechanism rear panel 406. The motion mechanism rear panel 406 is not restricted to be connected to the entire back of the motion mechanism, and only partially cooperates with the adjustment mechanism. In order to realize the tilting setting of the servo motor of the lifting mechanism, the motion mechanism bottom panel 402 is tilted.

[0025] The inner shell 2 is an open structure at the top, and the upper opening is for the motion mechanism to realize lifting. The inner shell 2 includes an inner side plate 201, an inner bottom plate 203 and an inner rear plate 202 arranged opposite to each other. The three can be connected through an inner frame 204, or directly welded.

[0026] The outer shell 1 includes two relatively arranged outer plates 101 and an outer rear plate 102. The connection between the two can be achieved by an outer frame 103 or direct welding. A switch box 104 is provided on the outer plate 101 of the outer shell 1. The switch box 104 is used to control the movement start and stop of the adjustment mechanism of the present application, i.e., the up and down fine-tuning and the front and back fine-tuning. Before use, it is convenient to adjust the rotation zero point 22 of the working platform of the CNC bending machine follower support device of the present invention to coincide with the origin 20 of the bending machine mold. It is also convenient to observe during adjustment, and it can avoid the use of a wire control box to cause a broken line and short circuit malfunction. For zero point confirmation, there will be an L-shaped ruler with a pointed tip at the front placed at the front end of the working platform. The tip of the ruler is referenced to coincide with the zero point position of the bending machine mold.

[0027] Of course, the location of the switch box 104 is not limited to the outer plate 101, and can also be located in other places that do not affect the circuit and are suitable for operation.

[0028] The lifting mechanism is the key to the realization of the follow-up material support of the CNC bending machine, especially the motion mechanism. At present, the existing technology uses multiple gears or dual servo motors to achieve dual lifting, and the error and failure rate of multi-drive motor coordination are affected. The working process is affected by the forward push and backward pull caused by lifting, which affects the bending size accuracy, and the aluminum plate or mirror plate 21 is scratched due to sliding on the lifting platform. The motion mechanism coordination in the present invention can well solve the above problems.

[0029] The lifting mechanism includes a working platform 3 and a motion mechanism, wherein the motion mechanism includes a servo motor and a plurality of motion arms, and the plurality of motion arms form a motion linkage body. The servo motor drives the motion mechanism lead screw 17, thereby driving the motion linkage body to move, thereby achieving the lifting of the working platform 3.

[0030] like Figure 4 As shown in the figure, the servo motor is a single drive motor (not shown in the figure, the motion mechanism gear box 405 includes a servo motor, the servo motor drives the gears in the motion mechanism gear box 405 to rotate, thereby driving the motion mechanism lead screw 17 to rotate), the motion mechanism bottom plate 402 is tilted, in order to achieve the initial position of the servo motor tilt, a rotating block 407 is provided under the servo motor, a rotating connecting block 403 is fixedly provided in the motion mechanism housing 4, the rotating connecting block 403 and the rotating block 407 cooperate to realize the rotation of the servo motor around the center of the rotating connecting block 403, and the motion mechanism lead screw 17 is sleeved with a motion mechanism moving block 407. The movable block 18 and the moving mechanism screw 17 adopt a high-precision and high-thrust ball screw. The moving mechanism screw 17 is between two relatively arranged third moving arms 7. The two sides of the rotating movement of the moving block 18 of the moving mechanism are respectively connected to the third moving arms 7. The rotation connection here can be that cylindrical protrusions are respectively provided on both sides of the moving block 18 of the moving mechanism, and holes are opened at corresponding positions on the third moving arm 7. The cylindrical protrusions are inserted into the holes for connection, and the other end of the cylindrical protrusions is provided with threads. By passing a nut on the other side of the third moving arm 7, the cylindrical protrusions are limited and connected. The rotation of the moving mechanism screw 17 ultimately drives the two third moving arms 7 to move together.

[0031] The third moving arm 7 is rotationally connected to the moving mechanism side plate 401 through the seventh point 907, and is rotationally connected to the second moving arm 6 through the fourth point 904. The other end of the second moving arm 6 is rotationally connected to the working platform 3 through the third point 903. The other end of the working platform 3 is connected to the first moving arm 5 through the first point 901. The other end of the first moving arm 5 is connected to the fourth moving arm 8 through the second point 902. The other end of the fourth moving arm 8 is rotationally connected to the moving mechanism side plate 401 through the fifth point 905. The middle of the fourth moving arm 8 is rotationally connected to the second moving arm 6 through the sixth point 906, thereby realizing that the moving linkage body drives the working platform 3 to rotate around the working platform rotation zero point 22.

[0032] The first point 901 of the first moving arm 5 and the third point 903 of the second moving arm 6 are connected to the working platform 3, and can be directly connected by rotation, or can be connected through the working platform connecting member 301, such as Figure 2 shown.

[0033] The fifth point 905 on the fourth moving arm 8 and the seventh point 907 on the third moving arm 7 are not on the same vertical plane. The housing is also provided with symmetrically arranged supporting members and moving members for movement.

[0034] The first point 901, the second point 902, the third point 903, the fourth point 904, the fifth point 905, the sixth point 906 and the seventh point 907 are the positions of the connection rotation points. The method of realizing the rotation connection is not limited. For example, the pin shaft rotates, and the position rotation of the corresponding point can be realized by the cooperation of the shaft and the hole, or the cooperation of the sleeve and the core, etc.

[0035] The fourth point 904 and the seventh point 907 on the third moving arm 7 , and the connection point between the moving mechanism lead screw 17 and the third moving arm 7 , are not on the same branch line, but are on the same plane, namely, the third moving arm 7 .

[0036] The seventh point 907 on the third moving arm 7 and the fifth point 905 on the fourth moving arm 8 are the moving fulcrums of the moving mechanism. Under the movement of the third moving arm 7, the other moving arms realize their own movements around the seventh point 907 on the third moving arm 7 and the fifth point 905 on the fourth moving arm 8, so that the moving linkage body drives the working platform 3 to rotate around the working platform rotation zero point 22. Avoid the bending size accuracy affected by the forward push and backward pull caused by the lifting during the working process, and secondly, the aluminum plate or mirror plate 21 may be scratched due to sliding on the lifting platform.

[0037] An operation panel 205 is provided on the inner front plate of the inner housing 2 , and an operation panel distribution board 2051 is connected to the operation panel 205 .

[0038] An opening is provided on the rear plate 406 of the motion mechanism, and the front and rear motion screw rod II 1102 passes through the aforementioned opening and realizes synchronous transmission with the front and rear motion screw rod I 1101 located below through a gear belt. Since the front and rear motion motor 11 is fixed on the inner rear plate, there is no need to reserve holes on the rear plate 406 of the motion mechanism to match the front and rear motion screw rod I 1101.

[0039] The moving part is a universal wheel 14, and the supporting part is an adjustable foot 13. More preferably, the universal wheel 14 has a locking device, or the universal wheel 14 and the fixed wheel 15 are used in combination. Two universal wheels 14 and two fixed wheels 15.

[0040] The adjustable foot 13 includes a foot connection block 1301 connected to the shell, and a socket is provided on the foot connection block 1301. A limit pin 1302 cooperates with the socket. The foot is rotatably connected to the foot connection block 1301 through a foot connection arm 1303. The rotational connection here adopts a pin shaft rotational connection in this embodiment. The socket is located outside the rotation point of the foot connection arm 1303. When the foot plays a supporting role, the foot connection arm 1303 is inclined downward at an angle to the horizontal plane. The limit pin 1302 is located above the foot connection arm 1303, limiting the upward rotation of the foot connection arm 1303.

[0041] Specifically, there are four adjustable feet 13, which are foldable and lift-up feet. The front two are in a straight line shape extending on both sides, extending to the outside of the equipment, which can better stabilize the left and right swing amplitude of the machine. The rear two feet are in an outward eight-shaped shape, with the left side slanted outwardly than the left side, and the right side slanted outwardly than the right side, and both extend to the outside of the equipment.

[0042] This structure facilitates the shaking of the bending machine, so that the device of the present invention can further enhance the tightness between the device of the present invention and the bending machine, and the device of the present invention will not be far away from the bending machine due to shaking. Because the two rear adjustment feet 13 are in an outward eight-shaped shape, and the foot connection arm 1303 is tilted outward and downward from the outer shell 1 of the device of the present invention, when the machine vibrates by the bending machine, such as the upward vibration of the device of the present invention, when the device of the present invention vibrates upward, the rotation connection point of the foot connection arm 1303 and the foot connection block 1301 moves upward in space. At this time, there will be an inward force through the foot connection arm 1303, driving the foot to move inward, that is, to move closer to the bending machine.

[0043] An adjustment mechanism is provided to achieve front-to-back and up-down fine-tuning to adapt to bending machines from different manufacturers. The up-down and up-down fine-tuning uses an independent control system to avoid mutual interference between circuits.

[0044] Specific structure of the adjustment mechanism: a symmetrically arranged moving mechanism connecting arm 404 is provided on the outer side of the moving mechanism shell 4, and a through hole is provided on the moving mechanism connecting arm 404, through which the front and rear sliding optical axis 10 passes, and a front and rear sliding shaft sleeve 16 is provided on the outer sleeve of the front and rear sliding optical axis 10, and the front and rear sliding shaft sleeve 16 is located between the front and rear sliding optical axis 10 and the through hole, connecting the lifting mechanism and the inner shell 2, and the inner shell 2 is open at the upper end, and is used for the up and down lifting movement of the moving mechanism.

[0045] A first through hole 2021 and a second through hole 2022 are provided on the inner rear plate 202 of the inner shell 2, and a forward and backward motion motor 11 is provided on the inner wall of the inner rear plate 202 at a position corresponding to the first through hole 2021, and a forward and backward motion screw rod Ⅰ1101 of the forward and backward motion motor 11 passes through the first through hole 2021, and the forward and backward motion screw rod Ⅱ1102 is above the forward and backward motion motor 11, and one end of the forward and backward motion screw rod Ⅱ1102 passes through the second through hole 2022, and the forward and backward motion screw rod Ⅱ1102 and the part of the forward and backward motion I exposed from the rear plate 406 of the motion mechanism realize synchronous transmission of the two forward and backward motion screw rods through a gear belt (this part is not shown in the accompanying drawings, but does not affect the understanding of those skilled in the art).

[0046] The inner rear plate 202 is also provided with a through groove 2023, which is used to set the up and down movement motor 12, the up and down movement screw rod 1201 and the first connecting block 1202 sleeved on the outside of the up and down movement screw rod 1201 to realize the up and down movement of the first connecting block 1202. The first connecting block 1202 is connected to the outer rear plate 102 of the outer shell 1.

[0047] The front and rear moving motor 11 drives the front and rear moving screw rod. In order to drive the moving mechanism to slide forward and backward along the front and rear sliding optical axis 10 through the rotation of the front and rear moving motor 11, the front and rear moving screw rod II 1102 is connected to the opening of the rear plate 406 of the moving mechanism through the nut matched with the front and rear moving screw rod II 1102. The connection method is not limited here, as long as the two are connected and the nut and the moving mechanism can be moved as one, such as welding, front and rear clamping on the rear plate 406 of the moving mechanism, etc., so that the moving mechanism can slide forward and backward on the front and rear sliding optical axis 10; the up and down moving motor 12 drives the up and down moving screw rod 1201, and the up and down moving screw rod 1201 drives the sleeved first connecting block 1202 to move up and down, because the first connecting block 1202 is connected to the outer rear plate 102 of the outer shell 1, so as to realize the overall up and down movement of the inner shell 2 and the moving mechanism. The bending machines of different manufacturers can be adapted by fine-tuning the front and back and up and down. The fine-tuning of the up and down front and back uses an independent control system to avoid mutual interference between circuits.

[0048] The through slot 2023 is an inverted T-slot, the up-and-down motion motor 12 is located at the horizontal part of the T-slot, the side wall of the first connecting block 1202 is connected to the outer shell 1, and the inner rear plate 202 and the outer rear plate 102 of the outer shell 1 are symmetrically provided with matching sliders 2024 and up-and-down motion rails 1021 at corresponding positions, and the other side of the slider 2024 is fixed to the inner rear plate 202 of the inner shell 2, and the lower surface of the upper top wall of the through slot 2023 abuts against the upper end of the up-and-down motion lead screw 1201, or a stopper is provided at the upper end of the up-and-down motion lead screw 1201, and the stopper abuts against the lower surface of the upper top wall of the through slot 2023, as shown in FIG. Figure 5 shown.

[0049] The fifth point 905 of the moving arm is tilted forward and on the outside of the outer shell of the moving mechanism. This solution can better exert the output kinetic energy of the servo motor, that is, the same power can lift heavier weights. The working platform rotation zero point 22 is designed according to the moving arm, the swing angle of the moving arm, and the speed ratio, and adopts an offset crank design. The fifth point of rotation point 905, the seventh point 907 and the working platform rotation zero point 22 are a three-point one-line structure, so that the CNC bending machine follow-up supporting device of the present invention has zero movement error and is not affected by the motion error of multiple powers, and the influence of factors such as multi-power signal interference or signal delay. The driving motor, that is, the servo motor, can run at the highest speed without generating offset errors, and the efficiency can be maximized. The forward three-point one-line design is also because the supporting machine is a mobile device, so that the CNC bending machine follow-up supporting device of the present invention and the bending machine must have a placement position, and the three-point one-line also solves the problem that the single-drive supporting device can achieve the rotation of the working platform around the zero point of the mold within a reasonable distance range without scratching the plate 21.

[0050] The aforementioned method for using the CNC bending machine follow-up support device is as follows: (1) The bending machine is equipped with an external grating ruler to collect data; (2) Push the CNC bending machine follow-up support device close to the bending machine through the universal wheel 14, adjust the foot 13 to be a foldable and lifted foot, pull out the limit pin 1302, turn the foldable and lifted foot down, and insert the limit pin 1302. The limit pin 1302 is located outside the rotation point of the foot; (3) The plate 21 to be processed is placed on the working platform 3. According to the parameters and structures of the bending machines of different manufacturers, the working platform 3 of the CNC bending machine follower support device is fine-tuned up and down or forward and backward through the adjustment mechanism to adapt to the bending machines of different manufacturers; (4) When the upper die of the bending machine just contacts the plate 21, the CNC bending machine follow-up support device of the present invention can memorize this point as the action point according to the numerical value of the external grating ruler; (5) When in use, just input the specifications of the bending machine V groove 19 and the plate thickness on the equipment operation panel 205 to lift synchronously; (6) When lifting, the servo motor starts, driving the motion mechanism lead screw 17 to rotate. The motion mechanism moving block 18 is sleeved on the outside of the motion mechanism lead screw 17. The motion mechanism moving block 18 rotates and is connected to the third motion arm 7. The third motion arm 7 and the first motion arm 5, the second motion arm 6, the third motion arm 7, the fourth motion arm 8 and the working platform 3 form a motion linkage body, so that the motion linkage body drives the working platform 3 to flip around the rotation zero point 22 of the working platform.

[0051] The motion mechanism uses a single-drive servo motor to drive the motion mechanism screw 17, and then drives several connected motion arms through the third motion arm 7, so that the motion linkage body drives the working platform 3 to rotate around the working platform rotation zero point 22, thereby lifting the working platform 3, avoiding the errors and failure rates of the multi-drive motor coordination in the lifting work, and also avoiding the bending size accuracy affected by the forward pushing and backward pulling caused by the lifting during the working process. Secondly, there may be problems such as scratches on the aluminum plate or mirror plate 21 due to sliding on the lifting platform.

[0052] The present invention provides a CNC bending machine follow-up support device that can memorize this point as the action point according to the numerical value of the external grating ruler, and then automatically calculate the movement ratio of the bending machine's downward pressing distance according to the thickness of the plate 21 and the size of the V-groove 19. The angle is between 0 degrees and 75 degrees (the commonly used right-angle bending is 45 degrees). The speed is automatically matched according to the operating speed of the bending machine, and it can work at high speed and stability.

[0053] The present invention uses a unique calculation formula to accurately calculate the servo motor lifting and feeding distance of the bending machine V-groove 19 size, plate thickness and the stroke distance required for pressing down the corresponding plate thickness. The lifting speed is completely synchronized with the bending machine by detecting the pressing speed of the bending machine. When in use, you only need to input the specifications of the bending machine V-groove 19 and the plate thickness to lift synchronously. This algorithm completely solves the error of processing different plate thicknesses with the same V-groove 19 (for example, the actual thickness of a plate with a nominal thickness of 2.0MM will vary from 1.6MM to 1.99MM. When entering the plate thickness data, you need to enter the actual plate thickness to achieve a near-zero deviation effect) Formula: Pressing amount = (V-groove opening - 2*plate thickness) / 2*. Specific implementation: 2

[0054] The difference between this embodiment and the embodiment 1 is that the front end of the outer shell 1 has two thread-adjustable support rods, which are convenient for maintaining a fixed stable distance from the bending machine. The other end of the support rod abuts against or is connected to the surface of the bending machine.

[0055] The aforementioned method for using the CNC bending machine follow-up support device is as follows: (1) The bending machine is equipped with an external grating ruler to collect data; (2) Push the CNC bending machine follow-up support device close to the bending machine through the universal wheel 14, adjust the foot 13 to be a foldable and lifted foot, pull out the limit pin 1302, turn and lower the foldable and lifted foot, and insert the limit pin 1302. The limit pin 1302 is located outside the rotation point of the foot. There are two threaded support rods at the front end of the device. One end of the support rod is against the surface of the bending machine, so that there is a fixed and stable distance between the device and the bending machine. (3) The plate 21 to be processed is placed on the working platform 3. According to the parameters and structures of the bending machines of different manufacturers, the working platform 3 of the CNC bending machine follower support device is fine-tuned up and down or forward and backward through the adjustment mechanism to adapt to the bending machines of different manufacturers; (4) When the upper die of the bending machine just contacts the plate 21, the CNC bending machine follow-up support device of the present invention can memorize this point as the action point according to the numerical value of the external grating ruler; (5) When in use, just input the specifications of the bending machine V groove 19 and the plate thickness on the equipment operation panel 205 to lift synchronously; (6) When lifting, the servo motor starts, driving the motion mechanism lead screw 17 to rotate. The motion mechanism moving block 18 is sleeved on the outside of the motion mechanism lead screw 17. The motion mechanism moving block 18 rotates and is connected to the third motion arm 7. The third motion arm 7 and the first motion arm 5, the second motion arm 6, the third motion arm 7, the fourth motion arm 8 and the working platform 3 form a motion linkage body, so that the motion linkage body drives the working platform 3 to flip around the rotation zero point 22 of the working platform. Specific embodiment 3

[0056] The difference between this specific embodiment and the specific embodiment 2 is that there is no adjustment mechanism, and it is not necessary to implement front-to-back and up-to-down fine-tuning to adapt to the bending machines of different manufacturers. In this embodiment, the bending machine can be customized, and there is no need for front-to-back and up-to-down fine-tuning. In this case, the CNC bending machine follow-up support device of the present invention only needs to use a servo motor to complete the lifting work. After the lifting is completed, the motion linkage body can also drive the working platform 3 to flip around the working platform rotation zero point 22.
