Description

Technical Field

[0001] The invention belongs to the technical field of loading and unloading brackets, and in particular relates to a loading and unloading bracket structure and system. Background Art

[0002] In the traditional aluminum bar extrusion process, the aluminum bar is heated evenly, and the temperature of the rod head and the rod tail is the same. The heat energy generated during the extrusion process causes the temperature of the rod tail to be too high, and the extrusion time needs to be extended to cool down, which wastes energy, increases costs, and affects production efficiency. The variable frequency gradient heating of the aluminum bar solves this problem. Through variable frequency heating, the axial gradient temperature of the same aluminum bar can be accurately controlled, so that the temperature of the aluminum bar gradually decreases from the beginning to the end. The aluminum bar needs to be lifted by a bracket during variable frequency gradient heating of the aluminum bar; Prior art application No. 202011323643.1 discloses a bracket structure and an operating method for loading and unloading parts, comprising: a support frame, a cylinder, a joint, a floating plate, a support plate, a guide column, a fixed plate, a fixed frame, a roller, a first temperature probe and a second temperature probe, the cylinder is arranged on the support frame, the joint is arranged on the cylinder, the floating plate is fixedly connected to the cylinder, and the support plate is fixedly installed on the top of the support frame. The bracket structure and the operating method for loading and unloading parts are reasonably designed, simple in structure, simple in use and easy to operate, and the induction structure is adjusted according to the size of the aluminum rod, and the displacement distance of the roller is adjusted by the induction structure. The bracket is controlled to align the aluminum rod with the heating device, so that the aluminum rod is heated evenly. The fixed frame adopts an integrated structure to improve the overall strength of the fixed frame, and then the stability of the roller is improved through the fixed frame. Although it has stronger size compatibility than traditional bracket equipment, the relative position between the two fixed frames cannot be moved, and the two rollers and the fixed frame are non-detachable fixed connections, which limits the size compatibility of the bracket. In addition, the bracket lacks an aluminum rod position adjustment mechanism. If the aluminum rod position is not appropriate during the heating process or the heating gap, the aluminum rod position can only be adjusted manually, which may cause safety problems if the operation is improper.

The size compatibility of the bracket can be increased by adjusting the distance between the two roller mounting seats 400. At the same time, the position of the aluminum rod 6 during the heating process can be mechanically adjusted through the design of the aluminum rod position fine-tuning mechanism 5.

[0021] Example 2 On the basis of Example 1, several groups of symmetrically arranged mounting seat moving components are rotatably connected in the roller base 4, and the mounting seat moving components correspond one to one with the roller mounting seat 400. The mounting seat moving components include an electric position adjustment screw 4000, and a position adjustment nut 4001 is threadedly connected to the electric position adjustment screw 4000. The position adjustment nut 4001 is fixedly connected to the bottom of the roller mounting seat 400, and the bottom of the position adjustment nut 4001 is slidably connected in the position adjustment screw mounting groove 4002.

[0022] The working principle and beneficial effects of the above technical solution are as follows: when adjusting the relative position between the two roller mounting seats 400, the electric position adjustment screw 4000 rotates to drive the position adjustment nut 4001 to move under the action of the thread, thereby driving the two roller mounting seats 4000 to move. During the movement, the bottom of the position adjustment nut 4001 slides along the position adjustment screw mounting groove 4002 to ensure the stability of the movement process.

[0023] Example 3 Based on Example 1, the roller mounting seat 400 includes a movable base 4003 and a mounting seat body 4004. The front side of the mounting seat body 4004 is rotatably connected to the movable base 4003 via a hinge shaft 4009. A micro angle adjustment cylinder 4006 is hinged inside the movable base 4003. The end of the micro angle adjustment cylinder 4006 away from the movable base 4003 is slidably connected to the bottom of the mounting seat body 4004 via a micro slider 4005.

[0024] The working principle and beneficial effects of the above technical solution are as follows: when in use, the inclination of the mounting seat body 4004 can be adjusted according to actual use requirements. During adjustment, the micro angle adjustment cylinder 4006 extends to push the mounting seat body 4004 to rotate around the hinge shaft 4009, thereby achieving the inclination of the mounting seat body 4004. The tiltable design of the mounting seat body 4004 increases the surface fit between the electric roller 401 and the aluminum rod 6 on the basis of adjusting the distance between the two roller mounting seats 400 to increase the compatibility of the bracket.

[0025] Example 4 Based on Example 3, the mounting seat body 4004 includes a hinge seat 4007 and a disassembly plate 4008, the hinge seat 4007 is rotatably connected to the movable base 4003, the disassembly plate 4008 is detachably connected to the hinge seat 4007, and an electric roller 401 is rotatably connected between the hinge seat 4007 and the disassembly plate 4008.

[0026] Preferably, the shape of the electric roller 401 is any one of a cylinder, a straight frustum, a curved frustum, and a special-shaped cylinder.

[0027] The working principle and beneficial effects of the above technical solution are as follows: when the electric roller 401 needs to be replaced, the disassembly plate 4008 is removed, the original electric roller 401 is taken out, the new electric roller 401 is installed on the hinge seat 4007, and the disassembly plate 4008 is installed on the hinge seat 4007, thereby realizing flexible replacement of the electric roller 401. The electric roller 401 of a cylinder, a straight-faced frustum, a curved frustum, or a special-shaped cylinder can be selected based on actual usage needs to better ensure the stability of the aluminum rod 6 during the lifting process.

[0028] Example 5 On the basis of Example 1, two symmetrically arranged traversal racks 402 are fixedly connected to the roller base 4 along its length direction, and two symmetrically arranged electric traversal gears 4020 are rotatably connected to the aluminum rod position fine-tuning mechanism 5, and the electric traversal gears 4020 are meshed with the two traversal racks 402 for transmission.

[0029] The working principle and beneficial effects of the above technical solution are as follows: when the fit or position of the aluminum rod 6 needs to be fine-tuned, the electric traversal gear 4020 rotates and moves along the traversal rack 402 to the position of the aluminum rod 6 to be adjusted under the action of the traversal rack 402.

[0030] Example 6 On the basis of Example 5, a fine-tuning actuator 500 is connected to the aluminum rod position fine-tuning mechanism 5 for sliding up and down, and the fine-tuning actuator 500 includes a vertical slide bar 501, one end of the vertical slide bar 501 is fixedly connected to a power supply connection block 502, and the other end of the vertical slide bar 501 is fixedly connected to a fine-tuning actuator block 503, a connecting elastic member 504 is sleeved on the vertical slide bar 501, and the fine-tuning actuator block 503 is located in an actuator block storage groove 505, and two symmetrically arranged electric push rods 506 are rotatably connected in the actuator block storage groove 505, and the fine-tuning actuator block Two symmetrically arranged abutment rod accommodating grooves 507 are provided on 503, a plurality of piston slide grooves 5070 are provided in the fine-tuning execution block 503, an electric piston 5071 is slidably connected in the piston slide groove 5070, the electric piston 5071 is connected to the inner wall of the piston slide groove 5070 by a buffer elastic member 5076, the electric piston 5071 includes an electromagnetic block 1 5072 and an abutment piston rod 5073, an electromagnetic block 2 5074 is provided in the piston slide groove 5070; an electric toggle wheel 5075 is rotatably connected to the middle part of the fine-tuning execution block 503.

[0031] Preferably, an auxiliary gradient cooling component is also provided in the aluminum rod position fine-tuning mechanism 5, and the auxiliary gradient cooling component includes a power supply connection block 2 508, and the power supply connection block 2 508 is used to cooperate with the power supply connection block 1 502. A cooling fan mounting groove 5080 is provided in the aluminum rod position fine-tuning mechanism 5, and filters 5081 are installed at the inlet and outlet of the cooling fan mounting groove 5080, and a cooling fan 5082 is rotatably connected in the cooling fan mounting groove 5080.

[0032] The working principle and beneficial effects of the above technical solution are as follows: when adjusting the position, the electric piston 5071 with appropriate height is selected to act. When acting, the electromagnetic block 2 5074 and the electromagnetic block 1 5072 corresponding to the electric piston 5071 lose power, and the electromagnetic block 1 5072 slides outward under the action of the buffer elastic member 5076 to make the abutting piston rod 5073 slide into the abutting rod receiving groove 507, and then the electric abutting rod 506 rotates until the free end of the electric abutting rod 506 abuts against the abutting piston rod 5073. With the rotation of the electric abutting rod 506, the fine-tuning actuator 500 gradually moves upward until it contacts the lower surface of the aluminum rod 6, and lifts up the aluminum rod 6. By lifting up and then putting down the aluminum rod 6, the aluminum rod 6 is driven to rotate in conjunction with the rotation of the electric toggle wheel 5075, and the position and posture of the aluminum rod 6 are adjusted to a suitable position and degree. When the aluminum rod 6 is heated in a gradient process, the heating temperature at a certain position is too high. In order to ensure that the aluminum rod 6 will not crack due to the temperature gradient, the aluminum rod position fine-tuning mechanism 5 is moved to the position to be cooled, and then the electric push rod 506 returns to its position. At this time, the power connection block 1 502 and the power connection block 2 508 are in contact, and the power connection block 1 502 and the power connection block 2 508 are energized. After power-on, the cooling fan 5082 rotates to dissipate heat at the position with excessively high temperature.

[0033] Example 7 Based on any one of embodiments 1-6, a loading and unloading bracket system includes an aluminum bar position fine-tuning mechanism control module, the aluminum bar position fine-tuning mechanism control module is used to control the operation of the aluminum bar position fine-tuning mechanism 5, and the aluminum bar position fine-tuning mechanism control module includes: A posture image acquisition unit is used to acquire the posture image of the aluminum bar 6 in the current monitoring period, and input the posture image into the trained posture image evaluation model to obtain the posture qualification evaluation value of the aluminum bar 6 in the current monitoring period; A contact pressure collection unit, used to collect the pressure exerted on each electric roller 401 on the roller mounting seat 400 during the current monitoring period; A position adjustment judgment execution unit is used to calculate the position adjustment demand coefficient of the aluminum bar 6 in the current monitoring period based on the posture qualification evaluation value of the aluminum bar 6 in the current monitoring period and the pressure on each electric roller 401. When the position adjustment demand coefficient of the aluminum bar 6 in the current monitoring period is greater than the preset position adjustment demand coefficient of the aluminum bar 6, the aluminum bar position fine-tuning mechanism 5 adjusts the position of the aluminum bar 6; The cooling judgment execution unit is used to collect the actual temperature values ​​at several collection points on the aluminum rod 6 and compare them with the preset temperature values ​​at several collection points. If the actual temperature value at the collection point is greater than the preset temperature value, the aluminum rod position fine-tuning mechanism 5 is controlled to cool the collection point.

[0034] The working principle and beneficial effects of the above technical solution are as follows: through the posture image acquisition unit, the system can obtain the posture image of the aluminum rod 6 in the current monitoring period in real time, and use the trained posture image evaluation model for analysis, ensuring real-time monitoring of the aluminum rod posture and providing accurate posture qualification evaluation values. The position adjustment judgment execution unit calculates the position adjustment demand coefficient of the aluminum rod in the current monitoring period based on the acquired posture qualification evaluation value and the roller pressure. When this coefficient exceeds the preset value, the aluminum rod position fine-tuning mechanism will automatically adjust to optimize the position and posture of the aluminum rod. The cooling judgment execution unit compares the actual temperature of the collection point with the preset temperature. The system can identify areas with excessively high temperatures and automatically start cooling measures to prevent cracks in the aluminum rod due to uneven temperature.

[0035] Example 8 On the basis of Example 7, based on the posture qualification evaluation value of the aluminum bar 6 in the current monitoring period and the pressure on each electric roller 401, the position adjustment requirement coefficient of the aluminum bar 6 in the current monitoring period is calculated as follows: (1); among which, The demand coefficient is adjusted for the position of the aluminum bar 6 in the current monitoring period, is the weight value of the posture qualification evaluation value, is the logarithm to base e, is the posture qualification evaluation value of aluminum bar 6 in the current cycle, is the standard posture qualification evaluation value of the aluminum rod 6, is the weight value of the pressure unevenness of the electric roller 401, n is the total number of the electric rollers 401, is the pressure exerted on the j-th electric roller 401.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the position adjustment requirement coefficient of the aluminum bar 6 in the current monitoring period is a comprehensive calculation based on the posture qualification evaluation value of the aluminum bar and the pressure unevenness of the electric roller, which ensures the reliability of the calculation result and provides a more accurate and mathematical method to judge and execute the position adjustment of the aluminum bar, reduces the need for human intervention, improves the intelligence and automation of the system, and ensures the stability and quality consistency of the aluminum bar 6 during the processing process.
