[0020] A bending machine slider moving assembly, comprising:

[0021] Connecting mechanism,

The wear-resistant guide plate 1 is adjustably installed on the rear side of the slider, and the adjustment direction is perpendicular to the rear wall direction of the slider. The layout direction of the wear-resistant guide plate 1 is parallel to the movement direction of the slider;

[0025] The guide wheel group 2 is installed at the rear of the slide plate and is attached to the wear-resistant guide plate 2.

[0028] In the present application, the side of the adjustment block is provided with two inclined surfaces distributed on the left and right, and the inclined surfaces gradually approach the axis of the connecting bolt along the direction close to the slider;

[0029] There are two groups of mounting holes, which are respectively arranged on the left and right sides of the wear-resistant guide plate 1, and the threaded holes correspond to the inclined positions of the corresponding adjustment blocks.

[0030] In the present application, the guide wheel group 1 and the guide wheel group 2 are both provided with two groups and are symmetrically distributed on the left and right sides;

[0031] The guide wheel group 1 is provided with two rollers distributed on the left and right, and the outer peripheral surfaces of the rollers are arranged on the left and right sides of the wear-resistant guide plate 1 in a rolling manner;

[0032] The guide wheel group 2 is provided with two rollers distributed front and back, and the outer peripheral surfaces of the rollers are rolled on the front and back side surfaces of the wear-resistant guide plate 2.

[0033] Compared with the prior art, the present invention aims to solve three technical problems:

[0034] 1. In the case of the ball screw driving the nut and slider to move up and down to bend the workpiece, due to processing errors or uneven force, non-vertical force is generated. The upper joint and the lower joint are matched through arc surfaces to achieve eccentric load bending. When the lower joint and the slide are offset due to lateral force, the disc spring and arc gasket installed on the bolt follow the offset to reduce the lateral force of the upper joint, thereby reducing the impact of the eccentric load on the ball screw, so that the force of the ball screw during bending is within the tolerable range, and thus can support the eccentric load bending within the set range. Before this mechanism is installed, the bending angle accuracy can only be guaranteed to be 0.5°, and the service life of the ball screw is 7,000 times; after installing this mechanism, the bending angle accuracy can be guaranteed to be 0.2°, and the service life of the ball screw is 10,000 times.

[0035] 2. When the ball screw drives the nut and the slider to move up and down to bend the workpiece, the eccentric load cannot be avoided or eliminated. Due to the objective existence of the eccentric load, the ball screw will still have a certain force in the non-vertical direction, which requires strict selection requirements when selecting the ball screw, resulting in a high cost of the ball screw. This application adds a connecting piece between the upper joint and the lower joint, and uses the two ends of the connecting piece to rotate in the vertical direction and the up and down deflection of the connecting end to achieve a slight deflection angle of the lower joint when it is subjected to lateral force. Since the deflection of this angle will cause the state of the connecting piece to change, this change will not change the horizontal state of the upper joint from a mechanical point of view, thereby eliminating the lateral force of the upper joint, thereby reducing the selection standard of the ball screw. Before this mechanism is installed, the bending angle accuracy can only be guaranteed to be 0.5°, and the service life of the ball screw is 7,000 times; after installing this mechanism, the bending angle accuracy can be guaranteed to be 0.12°, and the service life of the ball screw is 11,000 times after installing this mechanism.

[0036] 3. Since the off-center load cannot be eliminated, it can only be effectively reduced to a controllable range. In traditional skateboards, the off-center load limitation is often set on the front and rear sides of the wear-resistant guide plate to limit the front and rear, and the side is limited by rollers. When the off-center load occurs, the rollers on the side will be offset in the front and rear directions, causing the wear-resistant guide plate to float from the wear-resistant pad on one side, making the nut on the ball screw move stiffly, and then causing damage to the ball screw. The present application uses two-way guidance, using rolling linear guidance for the front and back and left and right, and has a certain clamping force on the wear-resistant guide plate, thereby reducing the downward resistance. Secondly, due to the existence of processing errors and assembly errors of the wear-resistant guide plate and the slider, the problem of non-parallelism of the installed wear-resistant guide plate relative to the ball screw occurs, resulting in problems with the straightness of the slider during processing, which further affects the bending accuracy. Therefore, an adjustment block and an adjustment screw for slightly adjusting the position of the adjustment block are added to the wear-resistant guide plate to fine-tune the parallelism of the wear-resistant guide plate and the ball screw, so as to complete the smooth up and down movement and achieve high-speed movement. Before installing this mechanism, the slider can only reach a maximum speed of 200mm / s. If it goes higher, there will be abnormal noise. The service life of the ball screw is 7000 times of use. After installing this mechanism, the slider can reach a maximum speed of 250mm / s, and the noise is 10 decibels lower than the original one. The service life of the ball screw is 12000 times of use.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] Embodiment 1, as Figures 1 to 5 As shown, a bending machine slider self-adjusting joint connection mechanism comprises:

[0054] A slider 10 is provided with a U-shaped groove, a mounting seat 11 is installed in the U-shaped groove, and an axial cavity is provided inside the mounting seat 11;

[0055] The lower joint component 20 is connected to the top of the mounting seat 11, and an axial hole 1 is provided in the middle of the lower joint component 20;

[0056] The upper joint component 30 is connected to the top of the lower joint component 20, and the upper joint component 30 and the lower joint component 20 are adaptively matched, and the middle part of the upper joint component 30 is provided with an axial hole 2;

[0057] A cover plate 40, the cover plate 40 is fixedly mounted on the top of the upper joint component 30;

[0058] The lead screw nut 50 has a lifting lead screw 51 matched therein. The lifting lead screw 51 and the lead screw nut 50 are installed in the axial cavity, the first axial hole and the second axial hole.

[0059] The top surface of the lower joint component 20 and the top surface of the upper joint component 30 are matched through arc surfaces;

[0060] The bottom surface of the lower joint component 20 is provided with a plurality of stepped holes 1 evenly distributed circumferentially upward, and the top surface of the upper joint component 30 is provided with a plurality of stepped holes 2 evenly distributed circumferentially downward, wherein the small holes of the stepped holes 2 are larger than the small holes of the stepped holes 3.

[0061] A bolt is inserted into the second stepped hole, and an upper arc gasket 21 and a lower arc gasket 22 are inserted in sequence at the bottom of the bolt and extend into the first stepped hole.

[0062] A plurality of disc springs 23 and locking double nuts 24 are mounted on the bolts located inside the stepped hole 1, and the locking double nuts 24 are located below the plurality of disc springs 23 .

[0063] The lead screw nut 50 is provided with a vertically distributed outer convex strip 52, and the middle of the cover plate 40 and the upper joint part 30 are both provided with an adaption groove 1, and the adaption groove 1 cooperates with the outer convex strip 52 to facilitate the upper and lower joint connection installation and hole alignment operation.

[0064] During installation, the lower joint component 20 and the mounting sleeve 11 are fixed by bolts, and the lower joint component 20 is installed on the top of the mounting sleeve 1. Then, the upper joint component 30 is matched on the top of the lower joint component 20 through the arc surface, and connected by bolts, upper arc gaskets, lower arc gaskets, disc springs, and locking double nuts. The cover plate 40 is put on the outside of the top of the screw nut 50 and installed on the top of the upper joint component 30 by bolts. The assembly of the structure is completed and the mounting sleeve is fixed on the skateboard 10 to complete the assembly. When in use, the lifting screw 51 is inserted into the screw nut 50 and driven by the servo motor to realize the up and down movement of the slide plate 10 to achieve plate processing. During the up and down movement of the slide plate 10, when the slider 10 is overloaded, when the lower joint and the slide plate are offset due to lateral force, the disc spring and arc gasket installed on the bolt follow the offset to reduce the lateral force of the upper joint, thereby reducing the influence of the overload on the ball screw, so that the force on the ball screw is within the tolerable range during bending, and thus can support the overload bending within the set range, and the lifting screw 51 is basically not affected by the lateral force.

[0065] Embodiment 2, as Figures 6 to 10 As shown, the difference from the first embodiment is the connection method of the lower joint component 20 and the upper joint component 30, which is specifically:

[0066] Three groups of circumferentially distributed connecting members 60 are installed and connected between the lower joint component 20 and the upper joint component 30 . The tops of the three connecting members 60 are installed on the bottom surface of the upper joint component 30 , and the bottoms are installed on the top surface of the lower joint component 20 .

[0067] The connecting member 60 includes an upper connecting head 61, a lower connecting head 62 and an intermediate connecting body 63. The two ends of the intermediate connecting body 63 are respectively hingedly connected to the upper connecting head 61 and the lower connecting head 62. The upper connecting head 61 is rotatably mounted on the upper joint member 30 along the Y axis, and the lower connecting head 62 is rotatably mounted on the lower joint member 20 along the Y axis. By combining the rotation of the connecting head's own axis and the rotation of the hinge point with the intermediate connecting body 63, when the lower joint member 20 is subjected to an eccentric load, the force on the upper joint member 30 is in the vertical direction and is not affected by the eccentric load, thereby reducing the selection criteria of the lead screw and further improving the bending accuracy and life of the lead screw.

[0068] The bottom of the upper joint component 30 is provided with an outer boss 31 extending downwards. The outer boss 31 is covered on the outer side of the lower joint component 20 to limit the eccentric load angle range of the lower joint component 20 and protect the internal connecting component 60.

[0069] During installation, the lower joint component 20 is installed on the top of the installation sleeve 11, and the two connecting heads of the connecting component 60 are respectively installed on the upper and lower joint components and rotated relative to each other to ensure that the connecting component 40 and the connecting component 60 are on the inner side of the outer boss 31, and then the joint component 30 is connected and fixed on the cover plate 40.

[0070] like Figures 9 to 13 As shown, a bending machine slider moving assembly includes the connecting mechanism of the above embodiment, and further includes:

[0071] Wear-resistant guide plate 70, wear-resistant guide plate 70 is provided with two groups on the left and right, wear-resistant guide plate 70 can be adjusted and installed on the rear side of slider 10, the adjustment direction is perpendicular to the rear wall direction of slider 10, and the layout direction of wear-resistant guide plate 70 is parallel to the movement direction of slider 10.

[0072] The wear-resistant guide plate 80 is provided with two groups, left and right, and is installed on the inner wall of the wall panel. The layout direction of the wear-resistant guide plate 80 is parallel to the movement direction of the slider 10.

[0073] A guide wheel assembly 90 is installed on the wall panel and fits on the wear-resistant guide plate 70.

[0074] The guide wheel set 100 is installed at the rear of the slide plate and fits on the wear-resistant guide plate 80.

[0075] like Fig.12 As shown, the wear-resistant guide plate 70 is provided with a plurality of mounting holes 71 , and connecting bolts and adjusting blocks 72 sleeved on the outside of the connecting bolts are installed in the mounting holes 71 , and the connecting bolts are used to install the wear-resistant guide plate 70 on the slider 10 .

[0076] A threaded hole is installed on the side of the wear-resistant guide plate 1 70 , and an adjusting screw 73 is installed in the threaded hole. The adjusting screw 73 is used to move the adjusting block 72 to the side away from the slider 10 .

[0077] like Fig.13 As shown, the side of the adjusting block 72 is provided with two inclined surfaces 74 distributed on the left and right, and the inclined surfaces 74 gradually approach the axis of the connecting bolt along the direction close to the slider 10;

[0078] There are two groups of mounting holes 71 , which are respectively arranged on the left and right sides of the wear-resistant guide plate 1 70 , and the threaded holes and the corresponding inclined surfaces 74 of the adjustment blocks 72 are located in corresponding positions.

[0079] The guide wheel set 1 90 and the guide wheel set 2 100 are both provided with two sets and are symmetrically distributed on the left and right sides;

[0080] The guide wheel assembly 90 is provided with two rollers distributed on the left and right sides, and the outer peripheral surfaces of the rollers are arranged on the left and right sides of the wear-resistant guide plate 70 in a rolling manner;

[0081] The guide wheel group 100 is provided with two rollers distributed front and back, and the outer peripheral surfaces of the rollers are rolled on the front and rear side surfaces of the wear-resistant guide plate 80 2.

[0082] After the self-adjusting connection of the skateboard 10 to set the off-load amount is performed via the connecting mechanism, the up, down, left and right positions of the skateboard 10 are further limited between the skateboard 10 and the wall panel via the guide wheel group 1 90 and the guide wheel group 2 100, that is, the off-load amount will be adjusted to be smaller than the off-load amount set by the connecting mechanism alone, thereby effectively reducing the off-load problem. However, in the past, the off-load guiding was only achieved by the sliding cooperation of the front and rear wear-resistant pads and the wear-resistant guide plates and the restriction of the lateral rollers. When off-load occurs, the wear-resistant guide plate and one of the wear-resistant pads will further abut against each other and float relative to the other wear-resistant pad, thereby increasing the processing resistance of the workpiece and making the movement of the screw nut 50 stiff. Secondly, the lateral rollers will move outward relative to the wall panel, further increasing the processing resistance. The present embodiment can move the adjusting screw 73 against the inclined surface 74 away from the side of the slide plate 10 by adjusting the adjusting screw 73, thereby ensuring that the wear-resistant guide plate 70 is always in vertical motion (parallel to the lead screw, i.e. parallel to the processing generatrix), and will not cause stiffness due to forward and backward motion relative to the guide wheel assembly 90 due to the off-load, thereby making the movement of the slide plate 10 smoother and achieving higher-speed movements.

[0083] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The replacement may be a replacement of a part of the structure, device, method step, or a complete technical solution. Any equivalent replacement or change according to the technical solution and the inventive concept of the present invention shall be covered within the protection scope of the present invention.
