[0002] A straightening machine is a device specially used for straightening metal materials. With a certain pressure, driven by the transmission device, the metal material undergoes plastic deformation, thereby achieving its straightening. The straightening principle of the straightening machine is to compress the material with a certain force, causing it to undergo plastic deformation, thereby achieving the straightening effect. The straightening machine can achieve precision requirements by straightening metal materials, thereby improving product quality. The straightening machine can greatly improve production efficiency, especially for some repetitive tasks, such as straightening of aluminum profiles, steel formwork, etc. The straightening machine can be completed quickly and with high quality, which can reduce the labor intensity of workers and thus improve production efficiency.
[0003] At present, when straightening and twisting square workpieces, this usually requires two devices, a straightening machine and a twisting machine. During the work, the workpiece needs to be moved back and forth between the two devices, which is time-consuming and labor-intensive, greatly reducing the straightening efficiency. Secondly, the sensor used to detect the bending amount of each point on the workpiece is fixed on the support detection seat. The sensor and the workpiece need to maintain contact during the measurement process. The straightening machine will throw the workpiece onto the support detection seat during operation. The main purpose is to ensure that the workpiece produces plastic deformation under pressure, thereby eliminating the original bending deformation. Therefore, when the workpiece thrown onto the support detection seat contacts the sensor, it is easy to cause the sensor to be affected by the impact force and cause damage.

[0016] The present invention has the following beneficial effects:
[0017] 1. In the fully automatic mobile gantry straightening and twisting machine, the height of the clamped workpiece can be adjusted through the cooperation of the first servo motor, the first servo hydraulic cylinder, the second mounting seat and the second servo hydraulic cylinder. The first displacement component fixed on the base can be adaptively adjusted according to the length of the workpiece. The first mechanical claw and the second mechanical claw can clamp the two ends of the workpiece. The twisting component arranged on the first mounting seat can achieve the purpose of adjusting the rotation angle of the rotating shaft, prompting the first mechanical claw to rotate, and can twist the bent and deformed workpiece to effectively eliminate the deformation on the workpiece and ensure the quality and performance of the workpiece. The weighing sensor can be installed through the several supporting and detecting seats arranged on the base. When the workpiece is bent, The weighing sensor can detect the value changes on both sides of the workpiece, and the bending amplitude of the workpiece can be automatically determined by the value changes on both sides of the workpiece. The second spring fixed between the mounting block and the support detection seat can realize that the weighing sensor can be hidden in the cavity when it is not working, so that when the workpiece falls on the support detection seat, it can avoid collision with the weighing sensor and cause damage. The set interference bar can move synchronously with the first mounting seat, so that the purpose of the interference bar and the interference wedge bar can be realized. When the workpiece falls into the support detection seat, the interference frame is prompted to move horizontally and conflict with the mounting block. The mounting block moves up with the weighing sensor in the support detection seat, which can realize the purpose of detecting the workpiece. The hidden weighing sensor greatly improves the protection performance during use.
[0018] When the detection head arranged in the supporting detection seat collides with the workpiece, the workers can judge the deformation condition of the workpiece by the change in the position of the detection head, and adopt the corresponding straightening processing direction. The working position of the straightening frame can be adjusted according to the length of the workpiece through the second displacement component, and the working position of the straightening head can be adjusted through the cooperation of the third servo hydraulic cylinder and the sliding bracket. When the workpiece is lateral bent, the slot arranged on the straightening head can be aligned and engaged with the workpiece, so that the side wall of the workpiece can contact the rotating roller rotatably connected in the straightening head. When the straightening head moves, the lateral bending of the workpiece can be straightened. When the workpiece is flatly bent, the position where the slot is opened in the straightening head is offset to one side of the workpiece, and the position where the slot is not opened appears above the workpiece. The third servo hydraulic cylinder arranged on the straightening frame can apply pressure on the straightening head, and the purpose of correcting the flat bent part of the workpiece can be achieved during the movement of the straightening head. The present application can complete the lateral bending straightening, plane bending straightening and twisting processing of the workpiece, saves the process of workpiece handling, greatly improves the straightening efficiency, and reduces the space occupied by equipment.
[0019] 2. In the fully automatic mobile gantry straightening and twisting machine, the second column arranged on the base can be elastically connected to the support detection seat through the fifth spring. When the workpiece is side-bent and straightened, if the straightening head encounters an obstacle formed by the support detection seat during movement, the moving straightening head can drive the interference rod to move synchronously. When the straightening head approaches the support detection seat, the interference rod can be in conflict with the trapezoidal interference block fixed on one side of the support detection seat, prompting the support detection seat to slide downward on the second column and automatically avoid it, thereby ensuring that the straightening head can move normally and unhindered to straighten the side-bent workpiece, greatly improving the straightening effect and efficiency of the side-bent workpiece.
[0020] 3. In the fully automatic mobile gantry straightening and twisting machine, the positioning push rod arranged in the cavity can be located on both sides of the support and detection seat. When the bent workpiece moves down to the support and detection seat for detection, the second contact bar can be driven to move horizontally synchronously during the horizontal movement of the contact frame, so that the second contact bar can push the first contact bar fixed on the positioning push rod to move synchronously during the movement, and the positioning push rod can push the workpiece horizontally in the support and detection seat to position and adjust the workpiece, so that the detection accuracy of the workpiece can be improved and the error can be reduced during the detection process.

[0039] The workpiece is hoisted to both ends of the first mounting seat 2 and the second mounting seat 3 by a hoisting device, and one end of the workpiece is clamped by a first mechanical claw 5 on one side of the first mounting seat 2. Figure 1-Figure 7 According to the length of the workpiece, the second servo motor 96 in the first displacement assembly drives the screw rod 94 to rotate on the two rectangular blocks 91, and the moving block 95 is threadedly connected to the screw rod 94, which can drive the moving seat 93 to move horizontally on the two slide bars 92, so that the position of the second mounting seat 3 can be adaptively adjusted according to the length of the workpiece, so that the second mechanical claw 7 set on the second mounting seat 3 can clamp the other end of the workpiece, the working height of the first mounting seat 2 can be adjusted by the first servo hydraulic cylinder 8, and the working height of the second mounting seat 3 can be adjusted by the second servo hydraulic cylinder 9. The first mechanical claw 5 and the second mechanical claw 7 release the clamping of the workpiece, so that the workpiece falls into the support detection seat 10. If the workpiece can conflict with the detection head 12, the first spring 13 accumulates force and the detection head 12 retracts into the slide groove 11, and the other end of the detection head 12 is released from one end of the support detection seat 10. When extending outward laterally, it is convenient for manual preliminary observation of the bending deformation of the workpiece to determine whether the workpiece needs to be straightened sideways. At the same time, the first mounting seat 2 and the second mounting seat 3 move downward mechanically, prompting the first mechanical claw 5 and the second mechanical claw 7 to move downward synchronously to avoid obstruction to the workpiece detection. The set interference bar 21 can move synchronously with the first mounting seat 2, so as to achieve the purpose of the interference bar 21 and the interference wedge bar 20 to interfere with each other.

The detection values of several weighing sensors 15 can be automatically obtained through the measuring system of the device to obtain the bending condition of the workpiece.
[0040] When the workpiece needs to be twisted, refer to Figure 1-Figure 2 The two ends of the workpiece are clamped and fixed by the first mechanical claw 5 and the second mechanical claw 7 respectively. When the output end of the twisting cylinder 202 rotatably connected to the yoke 201 is telescopically adjusted, the twisting cylinder 202 can drive the bar block 203 fixed at the end of the rotating shaft 4 to deflect, so that the first mechanical claw 5 drives one end of the workpiece to deflect, thereby achieving the purpose of twisting the workpiece. The rotation angle of the second mechanical claw 7 can be adjusted by the first servo motor 6, and the purpose of flipping and adjusting the straightening surface of the workpiece can be achieved, so that the workpiece can be omnidirectionally corrected;
[0041] When the plane of the workpiece is bent and needs to be straightened, the slide rail 221 provided in the second displacement assembly facilitates the sliding connection of the sliding block 222. When the third servo motor 224 fixed on the sliding block 222 drives the gear 225 to rotate on the rack 223, the purpose of pushing the straightening frame 22 to move horizontally during the straightening process can be achieved. The third electric push rod 38 can adjust the moving position of the straightening head 24 on the sliding bracket 37. The working contact surface of the straightening head 24 can be adjusted according to the bending condition of the workpiece plane, so that the part of the straightening head 24 without the slot 25 is located above the workpiece. The third servo hydraulic cylinder 23 fixed on the straightening frame 22 can adjust the vertical downward position of the straightening head 24, so as to apply the straightening pressure to the bending position of the workpiece plane to perform the straightening process;
[0042] When the workpiece is bent sideways and needs to be straightened, the position of the straightening head 24 needs to be adjusted by the third electric push rod 38, so that the slot 25 provided by the straightening head 24 can be aligned with the workpiece, so that the straightening head 24 can move downward to engage with the workpiece, and several equally spaced rotating rollers 26 on both sides of the slot 25 can be against the side of the workpiece. By adjusting the horizontal movement position of the straightening head 24, the rotating roller 26 can be used to straighten the side of the workpiece. By using a special straightening head 24, both the side bending straightening of the workpiece and the horizontal straightening of the workpiece can be completed.
[0043] When the two first guide holes 27 provided on the first mounting seat 2 are slidably connected with the two first guide rods 28 fixed on the base 1, the first servo hydraulic cylinder 8 can achieve a stable performance of adjusting the working height of the first mounting seat 2, and when the two second guide holes 29 provided on the second mounting seat 3 are slidably connected with the two second guide rods 291 fixed on the moving seat 93, the second servo hydraulic cylinder 9 can achieve a stable performance of adjusting the working height of the second mounting seat 3;
[0044] When the workpiece is dropped from a height onto the support and detection seat 10 during the straightening process, the greater the weight of the workpiece, the greater the downward impact force, which will cause deformation to the support and detection seat 10 and affect the use of the support and detection seat 10. In order to avoid the deformation of the support and detection seat 10 that affects the use, when the first support block 31 elastically connected to the first column 30 contacts the falling workpiece, the first support block 31 is prompted to slide on the first column 30, and the fourth spring 32 accumulates force, thereby reducing the impact force and improving the protection performance of the support and detection seat 10. The first electric push rod 33 fixed on one side of the straightening frame 22 can adjust the horizontal working position of the mounting frame 34 when the workpiece is straightened, so that the mounting frame 34 can be moved to the bottom of the workpiece. The two second electric push rods 35 fixed on the mounting frame 34 can adjust the working height of the second support block 36. When the workpiece is straightened, the second support block 36 can be urged to rest on both sides of the workpiece straightening point, thereby playing a supporting role and improving the straightening accuracy.
[0045] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 7 A second column 39 is fixed on the base 1, and the second column 39 is elastically connected to the support and detection seat 10 through a fifth spring 40. A trapezoidal interference block 411 is fixed to one side of the support and detection seat 10, and an interference rod 41 is fixed to one end of the straightening head 24.
[0046] In the prior art, when the workpiece is subjected to the lateral bending straightening process, since the workpiece is stuck on the support and detection seat 10, the support and detection seat 10 is likely to hinder the moving straightening head 24 during the process. When the straightening head 24 moves close to the support and detection seat 10, the worker needs to control the height of the support and detection seat 10. When the number of workpieces is large, it is time-consuming and laborious, which will greatly affect the straightening efficiency of the workpiece. Figure 1-Figure 3 When the straightening head 24 moves to straighten the side-bent workpiece, it can drive the interference rod 41 to move synchronously, and can achieve the purpose of interference with the trapezoidal interference block 411 fixed on one side of the support and detection seat 10, so that the trapezoidal interference block 411 drives the support and detection seat 10 to move downward, and at the same time, the support and detection seat 10 slides on the second column 39, and the seventh spring 43 accumulates force, so that the support and detection seat 10 can automatically avoid the process of the straightening head 24 straightening the side-bent workpiece, thereby greatly improving the straightening efficiency of the workpiece.
[0047] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 7 A positioning push rod 42 is provided in the cavity 14 , and the positioning push rod 42 is elastically connected to the support detection seat 10 through a seventh spring 43 . A first interference strip 44 is fixed on the positioning push rod 42 , and a second interference strip 45 is fixed on the interference frame 18 .
[0048] After the workpiece is initially straightened, it needs to be raised and turned over to adjust the workpiece straightening surface. After the adjustment, it moves down to the support detection seat 10 for bending detection. Position deviation occurs during the adjustment process, which will cause measurement errors. Each time, its position needs to be positioned and centered. Figure 4-Figure 5 When the workpiece moves down into the support detection seat 10 and is detected by the weighing sensor 15, the purpose of driving the second contact bar 45 to move synchronously during the horizontal movement of the contact frame 18 can be achieved, and the second contact bar 45 can be prompted to push the first contact bar 44 to move synchronously, and the positioning push rod 42 can be used to push the workpiece horizontally for positioning and adjustment, so that the accuracy of the workpiece is improved and the error is reduced during the detection process.
