Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to an automatic bending device for processing a semitrailer compartment plate. Background Art

[0002] Semi-trailers will be subjected to various dynamic and static forces during transportation, including the weight of the cargo, inertia force during driving, etc. By bending the car body panel, its mechanical structure can be changed to form a certain reinforcement effect, thereby significantly improving the bending and torsion resistance of the panel, ensuring that the car body can still maintain good structural integrity under heavy loads and complex road conditions, reducing the possibility of deformation or even breakage, and ensuring the safety of transportation. In addition, reasonable bending angles and shapes can enable the car body panel to be closely connected with other components such as the frame, achieving more precise assembly, which can not only improve the overall stability of the vehicle, but also optimize space utilization, making the internal space layout of the car body more reasonable and improving cargo loading efficiency.

[0003] At present, the bending process of the carriage plate mainly adopts the cold pressing bending method and the stamping method. The cold pressing bending method realizes the bending process through various forms of rollers for stable rolling. By changing the roller style, the most reasonable layout can be guaranteed. In addition, the punching and cutting process can also be completed online, and the bending process of the carriage plate can be realized without secondary processing; the stamping method uses a hydraulic cylinder to drive the pressure head to press the plate in the mold to realize the bending process of the carriage plate. In order to ensure the processing efficiency, these two methods both adopt an integrated molding processing method to realize the simultaneous bending of all the bending parts of the carriage plate. However, in the process of bending multiple bending parts of the carriage plate at the same time, the two ends of the bending part cannot slide under the pressure of the roller or the mold. Therefore, the two ends of the steel plate undergo plastic deformation during the stretching process, resulting in thinning of the plate, which makes the bending part of the carriage plate appear more obvious thinning, thereby affecting the forming quality of the carriage plate.

[0004] Therefore, it is necessary to provide an automatic bending device for processing a semi-trailer carriage plate, aiming to solve the above problems. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The fixed seat is usually located at both ends of the plate to fix and support the plate, while the limit plate is used to limit the movement range of the plate to prevent it from exceeding the predetermined path, so that the plate can maintain linear motion during the processing process and improve the processing accuracy and quality of the plate. The driving roller is driven by the motor to realize the loading and unloading of the plate, so that the plate can move stably to the bending position and realize unloading after bending. After the plate reaches the bending position, the hydraulic cylinder will intervene and bend the plate through the bottom pressure head. The use of the hydraulic cylinder can provide strong force and precise control to achieve high-quality bending effect.

[0019] Through the meshing between gear one and the movable block, the movable block is driven by the bidirectional spiral groove of the driving rod and is stuck between gear one under the limit that the roller screw cannot drive the block to move, so that the movable block drives the slider to move through gear one and meshes with gear two, thereby realizing the rotation of the side plate away from one end of the fixed seat and forming a bending groove. When the slider moves to the specified position, the driving rod that continues to move will drive the meshing with the turbine to disengage, completing the intermittent loading of the plate, so that the plate can be bent by the pressure head at this time, and the rotating side plate facilitates the unloading of the plate after bending.

[0020] The cam inside the movable sleeve is connected by sliding connection in the spiral groove on the outside of the reciprocating screw, so that the rotation of the reciprocating screw can drive the piston fixedly connected to one end of the movable sleeve to achieve reciprocating movement. The reciprocating piston pushes the hydraulic oil from the oil tank into the hydraulic cylinder body and squeezes the pressure head to move downward to achieve bending of the plate. The reciprocating screw is connected to the motor output shaft through a transmission belt and a drive rod, so that the motor can provide the downward pressing power of the pressure head, and cooperate with the loading and unloading of materials and the formation of the bending groove in the device to ensure the accuracy of the machining process.

[0039] Through the connection between the hydraulic cylinder body 701 and the oil tank 702, the hydraulic oil can be poured between the piston 1 705 and the piston 2 706. When the piston 1 705 moves, the hydraulic oil can push the piston 2 706 to move, so that the piston 2 706 can drive the pressure head 707 fixedly connected to its bottom to realize the bending processing of the plate. Through the sliding connection between the protrusion in the movable sleeve 703 and the spiral groove of the reciprocating screw 704, the rotating reciprocating screw 704 can drive the piston 1 705 to move back and forth to realize the reciprocating push of the hydraulic oil, so that the pressure head 707 can move up and down to complete the repeated bending of the plate, thereby realizing automated continuous bending processing.

The slider 903 is internally slidably connected with a movable block 905 at one end away from the transmission belt 901. A bidirectional spiral groove is provided on the outer side of the driving rod 902. The internal protrusion of the movable block 905 is slidably connected in the bidirectional spiral groove. The slider 903 is internally rotatably connected with a gear 1 907. The lower surface of the movable block 905 at one end away from the motor 6 is provided with a tooth groove adapted to the gear 1 907. The top of the gear 1 907 penetrates the slider 90 3 and meshingly connected with the tooth groove on the movable block 905, the outer side of the gear 1 907 is symmetrically fixedly connected with a roller screw 914, the outer side of the roller screw 914 is threadedly connected with a clamping block 915, the clamping block 915 is slidably connected to the inside of the slider 903, the inner wall of the support seat 2 is symmetrically provided with square grooves adapted to the clamping blocks 915, the clamping blocks 915 are all slidably connected to the square grooves on the inner wall of the support seat 2, the bottom inner wall of the support seat 2 is slidably connected with a connecting plate 904, and one end of the connecting plate 904 close to the motor 6 is fixedly connected with three groups of six supporting blocks 912, each group of two A worm 913 is rotatably connected between the support blocks 912, and the worm 913 is slidably connected to the outer side of the driving rod 902 through an internal protrusion. A worm wheel 911 adapted to the worm 913 is fixedly connected to the outer side of the mounting rod 910. A connecting block 906 is fixedly connected to the end of the movable block 905 close to the motor 6. The connecting block 906 is fixedly connected to the upper surface of the connecting plate 904 close to the end of the slider 903. The transmission belt 901 includes a belt and two transmission wheels. The driving rod 902 and the reciprocating screw 704 are fixedly connected to the two transmission wheels at one end away from the fixed seat 801.

[0041] The driving rod 902 can not only provide the power for the bending assembly to bend the plate through the transmission belt 901, but also can provide the power for the support assembly to drive the plate to be loaded and unloaded through the meshing connection between the worm 913 and the worm wheel 911, and the mounting rod 910 can provide the power for the support assembly to drive the plate to be loaded and unloaded. The side plate 803 can be rotated and installed away from one end of the motor 6 through the mounting shaft 909, so as to realize the forming and opening of the bending groove, facilitate the stable bending of the plate, and also can be opened to facilitate the unloading of the plate after bending. The gear 2 908 fixedly connected to the outside of the mounting shaft 909 is adapted to the bottom tooth groove of the slider 903, so that when the slider 903 moves toward the motor 6 driven by the movable block 905, the gear 2 908 can be pushed to rotate through the tooth groove at the bottom. The rotating gear 2 908 drives the side plate 803 to realize the forming and opening of the bending groove through the mounting shaft 909, and the bidirectional spiral groove on the outside of the driving rod 902 is connected with the inner protrusion of the movable block 905. The sliding connection makes it easy for the driving rod 902 to drive the movable block 905 to move back and forth. Since the bottom of the movable block 905 is meshed with the gear 1 907, and the roller screw 914 fixedly connected at both ends of the gear 1 907 cannot push the card block 915 to move, the gear 1 907 cannot rotate to achieve the jamming with the movable block 905. At this time, the movement of the movable block 905 can drive the slider 903 to move synchronously. The installation of multiple groups of support blocks 912 and worm gears 913 can be achieved through the connecting plate 904. The worm gear 913 slides on the driving rod 902 through the internal protrusion, so that during the movement of the worm gear 913, the driving rod 902 can still drive the worm gear 913 to rotate. When the worm gear 913 is meshed with the worm wheel 911, the rotating driving rod 902 can drive the installation rod 910 to provide the feeding power of the support assembly. The movement of the movable block 905 can drive multiple groups of worm gears 913 to move synchronously through the connecting block 906.

[0042] The supporting assembly includes a fixed seat 801 and a fixed plate 802 fixedly connected between the supporting seat 2 and the supporting plate 3, the end of the fixed plate 802 close to the fixed seat 801 is fixedly connected to a side plate 803, the end of the fixed plate 802 away from the fixed seat 801 is rotatably connected to another side plate 803, the side where the two side plates 803 are close to each other is fixedly connected to a chamfered plate 804, three driving rollers 805 are rotatably installed between the supporting seat 2 and the supporting plate 3, and the tops of the driving rollers 805 all pass through the top of the fixed seat 801 and are flush with its upper surface.

[0043] The fixed seat 801 can support the plate, and cooperate with the limit plate 4 to limit the movement range of the plate and prevent it from exceeding the predetermined path, so that the plate can maintain linear motion during processing and improve the processing accuracy and quality of the plate. The fixed plate 802 can support the bottom of the bent plate, and the chamfering plate 804 can achieve chamfering to reduce the stress of the bent part. The chamfer size of this part is small and cannot affect the unloading of the plate. The bending groove can be formed and opened by rotating the side plate 803, which is convenient for bending and unloading after bending.

[0044] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0045] The initial state is as follows: the slider 903 is located inside the support seat 2 near one end of the transmission belt 901, the bottom tooth groove of the slider 903 is about to engage with the gear 2 908, the block 915 is located between the slider 903 and the roller screw 914, the movable block 905 and the gear 1 907 are meshed with each other, the worm wheel 911 is meshed with the end of the worm 913 near the motor 6, the piston 1 705 is located at the end of its stroke closest to the transmission belt 901, and the piston 2 706 and the pressure head 707 are at the top.

[0046] The steps of sheet metal processing are as follows:

[0047] Loading of plates: first, the operator needs to place the plates between the fixed seat 801 and the limiting plate 4, and then start the motor 6 so that its output shaft drives the driving rod 902 to rotate. Since the worm 913 slides on the outside of the driving rod 902 through the protrusion, the rotating driving rod 902 drives the worm 913 to rotate through the protrusion, and the rotating worm 913 drives the worm wheel 911 meshing with it to rotate synchronously. The rotating worm wheel 911 drives the mounting rod 910 fixedly connected to it to rotate, and the rotating mounting rod 910 drives the driving roller 805 fixedly connected to its outside to rotate. The rotating driving roller 805 pushes the plate on its top to move stably along the fixed seat 801 and the limiting plate 4 between the support seat 2 and the support plate 3 to realize loading;

[0048] When the driving rod 902 is rotating, the bidirectional spiral groove on the outer side thereof drives the movable block 905 to move through the internal protrusion of the movable block 905. When the gear 1 907 is stuck, the movable block 905 drives the slider 903 to move toward one end of the motor 6. The movable slider 903 can drive the gear 2 908 to rotate through the meshing connection with the gear 2 908 at the bottom tooth groove. The rotating gear 2 908 drives the internal fixed installation shaft 909 to rotate synchronously counterclockwise. The rotating installation shaft 909 drives the side plate 803 away from one end of the fixed seat 801 to rotate, and forms a bending groove with the other side plate 803 and the fixed plate 802, so as to facilitate the plate to move to its top end to realize bending processing.

[0049] The rotation of the driving rod 902 can drive the reciprocating screw 704 to rotate through the transmission belt 901, and the reciprocating screw 704 drives the movable sleeve 703 to move back and forth through the sliding connection between the outer spiral groove and the inner protrusion of the movable sleeve 703, and the reciprocating movable sleeve 703 drives the piston 1 705 fixedly connected thereto to move back and forth, and the reciprocating piston 1 705 drives the piston 2 706 to move up and down through the hydraulic oil, and the moving piston 2 706 drives the pressure head 707 fixedly connected thereto to move back and forth;

[0050] During the loading process of the plate, the slider 903 moves to the end of its stroke closest to the motor 6, and the clamping block 915 is aligned with the square groove symmetrically opened on the inner wall of the support seat 2, the movable block 905 drives the connecting plate 904 driven by the connecting block 906 to move to the end of its stroke closest to the motor 6, and the worm 913 rotatably mounted on the connecting plate 904 through a set of two supporting blocks 912 also moves to the end of its stroke closest to the motor 6, and the pressure head 707 moves downward to fit the upper surface of the plate;

[0051] Bending of the plate: When the slider 903 moves to the end of its stroke closest to the motor 6, the pressure head 707 fits with the upper surface of the plate, and the worm 913 moves to the end of its stroke closest to the motor 6. At this time, the continued rotation of the output shaft of the motor 6 can drive the movable block 905 to move through the driving rod 902, and the movable block 905 can drive the gear 1 907 to rotate through the engagement with the gear 1 907. The rotating gear 1 907 drives the roller screw 914 to rotate, and the rotating roller screw 914 drives the block 915 to move into the square groove, so as to realize the fixing of the slider 903 at this position, ensure the fixing of the position of the rotating side plate 803 after rotation, and avoid looseness affecting the bending quality;

[0052] When the movable block 905 moves in the slider 903, the movable block 905 can drive the connecting plate 904 to move through the connecting block 906, and the connecting plate 904 drives the worm 913 to move through a set of two supporting blocks 912, and the worm 913 and the worm wheel 911 are engaged and disengaged at this time, thereby realizing intermittent feeding of the plate, so as to provide the time required for bending;

[0053] When the sheet material stops being fed, the driving rod 902 that continues to rotate drives the reciprocating screw 704 to rotate through the transmission belt 901, and the rotating reciprocating screw 704 drives the movable sleeve 703 to move, and the movable sleeve 703 drives the piston 1 705 fixedly connected thereto to move and push the hydraulic oil, so that the hydraulic oil drives the pressure head 707 to move downward through the piston 2 706 to achieve bending and forming of the sheet material in the bending groove;

[0054] The movable sleeve 703 is moved upwards by the movable sleeve 703. When the surface of the movable sleeve 703 is flush with the surface of the plate, the driving rod 902 drives the movable block 905 to move into the slider 903 and is about to mesh with the gear 1 907. At the same time, the movable block 905 drives the worm 913 to mesh with the worm wheel 911 through the connecting block 906 and the connecting plate 904. At this time, the driving rod 902 that continues to rotate can drive the movable block 905 to completely enter the slider 903, and drive the clamping block 915 to disengage from the square groove through the gear 1 907. The continued movement of the movable block 905 can push the slider 903 to drive the gear 2 908 to rotate to realize the synchronous rotation of the side plate 803. The worm 913 and the worm wheel 911 resume meshing. At this time, the rotating worm 913 can also drive the plate to move to realize the unloading of the bent part. This can be repeated to complete the processing of multiple bends on the plate.
