Description
Technical Field
[0001] This utility model relates to the field of aluminum rod clamping and feeding devices, and in particular to a precision clamping and feeding device for aluminum rods. Background Technology
[0002] With the stable, continuous and rapid development of my country's national economy and high technology, my country's aluminum smelting and aluminum profile processing industries have developed very rapidly. In the 21st century, China's aluminum processing industry has closely combined with the needs of market and scientific development, and has gradually completed the transformation of traditional aluminum processed materials into modern aluminum processed materials. As a result, the varieties of aluminum processed profiles in China have undergone tremendous changes, among which aluminum rods are widely used as a raw material for aluminum profile processing.
[0003] In existing aluminum bar processing, raw aluminum bars are often cut to a suitable length before being placed into the extrusion chamber of an extruder using a clamping and feeding device to be extruded into various fixed-shape aluminum products. During clamping, two clamping plates are typically moved horizontally to hold the circumference of the aluminum bar for feeding. However, these clamping plates are mostly horizontal, resulting in limited contact area between the plates and the aluminum bar, which cannot adequately clamp the material. In the event of device vibration or other accidents, the clamping plates are prone to loosening, causing the aluminum bar to fall. To address these issues, a solution is proposed below. Utility Model Content
[0004] The purpose of this invention is to provide a precision clamping and feeding device for aluminum bars to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A precision clamping and feeding device for aluminum bars includes a support plate. Two hydraulic cylinders are mounted on the top of the support plate, and the piston rods of both hydraulic cylinders pass through the support plate. A connecting frame is fixed on the piston rod of each hydraulic cylinder. Two sets of clamping plates are rotatably arranged at the bottom of the support plate. Connecting components that connect to the clamping plates are respectively provided at the bottom of the support plate. Both clamping plates are arc-shaped. A sliding groove is formed on the clamping plate, and one end of the clamping plate passes through the sliding groove. A connecting shaft is installed between the connecting frame, the clamping plates, and the clamping plates. Both clamping plates are rotatably mounted on the connecting shaft. A driving component for moving the support plate is also provided on the top of the support plate.
[0007] Preferably, the connecting assembly includes multiple support blocks and multiple connectors. Each support block is fixed to the bottom of the support plate and has a trapezoidal structure. Each connector is hinged to the support block, and the end of each connector away from the support block is hinged to the clamping plate and the clamping plate.
[0008] Preferably, the drive assembly includes a support frame, a second support plate, and two electric slide rails. Both electric slide rails are mounted on the top of the support frame. Two support rods are mounted on the bottom of the second support plate, and the bottoms of the two support rods are respectively connected to the two electric slide rails. Multiple hydraulic cylinders are mounted on the top of the second support plate, and the piston rods of each hydraulic cylinder penetrate the second support plate. The piston rods of the hydraulic cylinders are fixedly connected to the top of the first support plate.
[0009] Preferably, the bottom of the second support plate is also equipped with multiple second support rods, which are respectively arranged on both sides of the first support rod. Each second support rod has a roller rotatably mounted at its bottom. The top of the support frame has two wide slots, and the electric slide rail is installed in the middle of the wide slots. The rollers rotate and slide within the wide slots, and the rollers have a concave structure.
[0010] Preferably, the bottom of the connecting frame is provided with an inner groove, one end of the clamping plate one and the clamping plate two are both disposed in the inner groove, and the connecting shaft is rotatably disposed in the inner groove.
[0011] Preferably, both the first clamping plate and the second clamping plate have anti-slip textures on their inner walls.
[0012] Beneficial effects: When it is necessary to clamp and feed aluminum bars, hydraulic cylinder two can be activated first. Hydraulic cylinder two pushes support plate one to move, so that clamping plate one and clamping plate two at the bottom of support plate one correspond to the aluminum bar. Then, hydraulic cylinder one can be activated again, which pushes the connecting frame to move. The connecting frame will rotate clamping plate one and clamping plate two through the connecting shaft, thus clamping the aluminum bar. Both clamping plate one and clamping plate two have arc-shaped contact, which can better contact the outer wall of the aluminum bar and achieve more precise clamping of the aluminum bar. By setting anti-slip texture on the outer wall of clamping plate one and clamping plate two, the friction effect can be increased to achieve the anti-slip function. Attached Figure Description

[0018] See Figures 1 to 4 As shown, a precision clamping and feeding device for aluminum bars includes a support plate 1. The top of the support plate 1 is provided with a drive component 9 for moving the support plate 1. When the aluminum bar is cut and needs to be clamped and fed, the drive component 9 can be started first. The drive component 9 drives the support plate 1 to move so that the support plate 1 can correspond to the aluminum bar.
[0019] The drive assembly 9 includes a support frame 91, a second support plate 92, and two electric slide rails 93. Both electric slide rails 93 are mounted on the top of the support frame 91. Two first support rods 94 are mounted on the bottom of the second support plate 92, and their bottoms are connected to the two electric slide rails 93 respectively. Each electric slide rail 93 has a slider, and the first support rods 94 are fixedly connected to the sliders. The second support plate 92 is supported by the first support rods 94. Multiple second hydraulic cylinders 95 are mounted on the top of the second support plate 92. The piston rods of each second hydraulic cylinder 95 pass through the second support plate 92 and are fixedly connected to the top of the first support plate 92. When the height of the first support plate 91 needs to be adjusted, the second hydraulic cylinder 95 can be activated, and its piston rod will push the first support plate 91 to move, allowing it to be moved to the specified height.
[0020] Two hydraulic cylinders 12 are mounted on the top of the support plate 1. The piston rods of both hydraulic cylinders 12 pass through the support plate 1. A connecting bracket 3 is fixed on the piston rod of the hydraulic cylinders 12. Two sets of clamping plates 14 and clamping plates 25 are rotatably mounted on the bottom of the support plate 1. Connecting components 6 are respectively provided on the bottom of the support plate 1 to connect with clamping plates 14 and clamping plates 25. Clamping plates 14 and clamping plates 25 are rotatably connected to the support plate 1 through the connecting components 6. When the support plate 1 is aligned with the aluminum rod, the clamping... The first clamping plate 4 and the second clamping plate 5 are in an unfolded state, which facilitates the subsequent rotation of the first clamping plate 4 and the second clamping plate 5, thereby achieving the clamping of the aluminum rod. Both the first clamping plate 4 and the second clamping plate 5 are arc-shaped structures, which can better contact the aluminum rod, increase the contact area, and ensure the stability of the clamping. The first clamping plate 4 is provided with a sliding groove 7, and one end of the second clamping plate 5 passes through the sliding groove 7. A connecting shaft 8 is installed between the connecting frame 3, the first clamping plate 4 and the second clamping plate 5, and the first clamping plate 4 and the second clamping plate 5 are rotatably mounted on the connecting shaft 8.
[0021] The connecting assembly 6 includes multiple support blocks 61 and multiple connectors 62. Each support block 61 is fixed to the bottom of the support plate 1. The support block 61 has a trapezoidal structure. Each connector 62 is hinged to the support block 61. The end of each connector 62 away from the support block 61 is hinged to the clamping plate 4 and the clamping plate 5 respectively. When the clamping plate 4 and the clamping plate 5 need to clamp and feed the aluminum rod, the hydraulic cylinder 2 can be activated first. The hydraulic cylinder 2 pushes the connecting frame 3 to move. The bottom of the connecting frame 3 has an inner groove 31. One end of the clamping plate 4 and the clamping plate 5 is set in the inner groove 31. The connecting shaft 8 rotates. The connecting shaft 8 is rotatably connected to the two ends of the inner groove 31. When the connecting frame 3 moves, it will drive the connecting shaft 8 to move together. The clamping plate 1 4 and the clamping plate 2 5 are connected to the support block 61 through the connecting piece 1 62. The connecting shaft 8 is rotatably connected to the clamping plate 1 4 and the clamping plate 2 5. When the connecting shaft 1 moves, it will drive the clamping plate 1 4 and the clamping plate 2 5 to move. Since one end of the clamping plate 1 4 and the clamping plate 2 5 is limited by the connecting piece 1 62, the connecting shaft 8 will drive the clamping plate 1 4 and the clamping plate 2 5 to rotate when it moves, so as to achieve precise clamping of the aluminum rod.
[0022] Both clamping plate 4 and clamping plate 5 have anti-slip textures on their inner walls. By designing anti-slip textures on the inner walls of clamping plate 4 and clamping plate 5, the friction between clamping plate 4, clamping plate 5 and aluminum rod can be increased, thereby better clamping the aluminum rod.
[0023] After the aluminum rod is clamped, hydraulic cylinder 2 (95) can be activated to lift support plate 1. At this time, two electric slide rails (93) are activated, which moves two support rods (94). Support rods (94) move the top support plate (92), which in turn moves the bottom support plate (1), thus transporting the aluminum rod to the designated position. After the aluminum rod is in the designated position, hydraulic cylinder 2 (95) is restarted. The piston rod of hydraulic cylinder 2 (95) pushes support plate 1 downward. After support plate 1 is in the designated position, hydraulic cylinder 2 (2) is activated to retract its piston rod, causing clamping plate 4 (4) and clamping plate 2 (5) to rotate in opposite directions. Clamping plate 4 (4) and clamping plate 2 (5) can then release the aluminum rod, thus achieving the clamping and feeding of the aluminum rod.
[0024] The bottom of the second support plate 92 is also equipped with multiple second support rods 96, which are respectively set on both sides of the first support rod 94. Each second support rod 96 has a roller 97 rotatably mounted at its bottom. The top of the support frame 91 has two wide slots, and the electric slide rail 93 is installed in the middle of the wide slots. The rollers 97 rotate and slide within the wide slots. The rollers 97 have a concave structure. By designing the rollers 97 as concave structures, interference between the rollers 97 and the electric slide rail 93 is prevented. When the second support plate 92 moves, it will drive the second support rods 96 at the bottom to move. The second support rods 96 will drive the rollers 97 at the bottom to move within the wide slots. Through the design of the second support rods 96, the second support plate 92 can be better supported, preventing the second support plate 92 from shaking during movement.
[0025] Working principle: When it is necessary to clamp and feed the aluminum rod, hydraulic cylinder 295 can be activated first. Hydraulic cylinder 295 pushes support plate 1 to move, so that support plate 1 moves to the specified height. Clamping plate 4 and clamping plate 5 at the bottom of support plate 1 will correspond to the aluminum rod and be set on both sides of the aluminum rod respectively. At this time, hydraulic cylinder 2 can be activated. Hydraulic cylinder 2 pushes connecting frame 3 to move. Connecting frame 3 will drive clamping plate 4 and clamping plate 5 to rotate through connecting shaft 8. The aluminum rod is clamped by the clamping plate 25. Then, the hydraulic cylinder 295 is activated to retract the piston rod of the hydraulic cylinder 295, which drives the support plate 1 and the aluminum rod to move. Then, the electric slide rail 93 is activated, which drives the support plate 292 to move, thereby moving the aluminum rod to the designated position. Then, the hydraulic cylinder 295 is activated again to lower the support plate 1 to the designated height. Finally, the hydraulic cylinder 2 is activated to realize the rotation of the clamping plate 4 and the clamping plate 25, and the aluminum rod can be sent to the designated position for subsequent processing.
