Description
Technical Field
[0001] This invention relates to the field of furniture manufacturing technology, and in particular to a high-efficiency and energy-saving bending device. Background Technology
[0002] With the changing lifestyles of today, all kinds of chairs are emerging on the market. Some of these chairs use complex metal rods, which are made by bending raw metal rods multiple times. Because the metal rods are round, they are prone to slippage. This causes the metal rods to shift in position when bending on the bending plate of the bending table, resulting in a shift in the bending distance of the bent metal rod. Therefore, a high-efficiency and energy-saving bending device is proposed. Summary of the Invention
[0003] To address at least one of the aforementioned technical shortcomings, this invention provides a high-efficiency and energy-saving bending device, comprising a base, an extension platform on one side of the base, a first drive motor installed within the extension platform, a push rod cylinder installed at the upper end of the extension platform, the push rod cylinder being placed through a metal rod in the middle of the base, a hopper above the metal rod, a connecting cylinder in the middle of the base, a rotating seat connected to the connecting cylinder, a platform above one side of the rotating seat, a second drive motor installed within the platform, a rotating disk below the second drive motor, a third drive motor below the middle of the rotating seat, a first transmission cylinder below the third drive motor, a second transmission rod on one side of the first transmission cylinder, and transmission discs on both sides of the first transmission cylinder and the second transmission rod.
[0004] Furthermore, the transmission disc is provided with concave arc-shaped transmission grooves arranged in a circumferential array. The first transmission cylinder and the second transmission rod are arranged circumferentially within the transmission grooves. The inner wall of the machine base is provided with a mounting groove. The transmission disc is embedded and installed in the mounting groove. The transmission disc on the other side is installed below the rotating seat through a fixing plate.
[0005] Furthermore, the second transmission rod is located below the first transmission cylinder, and the outer wall of the first transmission cylinder is provided with a clockwise spiral groove. A transmission belt connecting groove is provided on one side of the first transmission cylinder, and a transmission belt is sleeved on the output end of the third drive motor. The transmission belt is connected to the transmission belt connecting groove.
[0006] Furthermore, a mounting hole is provided in the middle of the first transmission cylinder, and a straight rod is fixedly connected in the mounting hole. Both sides of the straight rod pass through the transmission groove of the transmission disc.
[0007] Furthermore, the first transmission cylinder is made of a flexible material, and the transmission belt is made of an elastic material.
[0008] Furthermore, a protruding rod is provided on one side of the connecting cylinder, and a material strip is sleeved on the protruding rod. A through circular groove arranged in an annular array is provided outside the material strip. The hopper is bucket-shaped, and a discontinuous ring plate is provided at the bottom of the hopper. A metal rod inlet is provided at the connection between the ring plate and the hopper, and the opening width is slightly larger than the diameter of the metal rod. A through groove with the same shape as the transmission groove is provided on the other side of the connecting cylinder.
[0009] Furthermore, the bottom of the rotating seat is provided with a semi-circular seat tooth, the output end of the first drive motor is provided with a turntable, the outer wall of the turntable is provided with rotating teeth, the seat tooth meshes with the rotating teeth on the outer wall of the turntable, the middle of the rotating seat is also provided with an extension plate to facilitate further unloading of the rotating seat, and the bottom of the turntable is provided with a movable embedded bending head.
[0010] Furthermore, a through-hole is provided in the middle of the machine base to facilitate the insertion of a metal rod, and the distance and height of the material hole from the side wall of the machine base are equal.
[0011] Beneficial effects:
[0012] 1. Metal rods can be placed in the hopper. The openings between the hopper and the ring plate allow only one metal rod to pass through at a time. After the metal rod passes through the opening and falls downwards, it falls into the uppermost circular groove of the conveyor belt. The conveyor belt rotates downwards under the balance of gravity. At this time, the metal rods will enter the circular grooves of the annular array one by one. After the push rod cylinder pushes the metal rod to slide in the material channel connected to the material hole, the metal rod falls into the material channel. At the same time, the circular grooves on one side of the conveyor belt are all equipped with metal rods, while the circular grooves on the other side are hollow. Due to the gravity of the metal rods, the conveyor belt will continue to rotate, which avoids material collisions and achieves the effect of automated feeding.
[0013] 2. When the metal rod enters the material hole, the first drive motor is energized to drive the turntable to rotate. At the same time, the rotating seat is also rotated through the meshing seat teeth. After the rotating seat rotates, it drives the transmission disk connected to the bottom of the fixed plate to rotate as well. This causes the two first transmission rods and one transmission cylinder embedded in the transmission groove of the transmission disk to move along the concave arc trajectory, so that the two first transmission rods and one transmission cylinder converge towards the material hole, achieving the clamping effect on the metal rod in the material hole. At the same time, the third drive motor is energized to drive the transmission belt, causing the first transmission cylinder to rotate as well. At this time, the flexible material of the first transmission cylinder comes into contact with the outer wall of the metal rod. The clockwise rotation of the spiral groove generates a forward force. After the first transmission cylinder continues to rotate, the contact with the metal rod will cause the metal rod to move forward a certain distance, achieving the effect of controlling the precise movement of the metal rod, thereby further improving the accurate bending effect of the metal rod.
[0014] 3. After the metal rod reaches the outlet at the side of the machine base, the second drive motor inside the base is energized to rotate the fixed turntable at the output end. After the turntable rotates, the two bending heads pass through and bend the metal rod in the middle. At the same time, the movable bending head will generate a force in the same direction as the metal rod is gradually bent after the turntable rotates, so that the contact surface of the metal rod continues to change, thereby further reducing the probability of indentations on the metal rod.

[0028] This embodiment provides a high-efficiency and energy-saving bending device, including a base 1. An extension platform 101 is provided on one side of the base 1. A first drive motor 2 is installed in the extension platform 101. A push rod cylinder 3 is installed at the upper end of the extension platform 101. The push rod cylinder 3 is placed through a metal rod in the middle of the base 1. A hopper 4 is provided above the metal rod. A connecting cylinder 103 is provided in the middle of the base 1. A rotating seat 5 is sleeved on the connecting cylinder 103. A base 502 is provided on one side of the rotating seat 5. A second drive motor 506 is installed in the base 502. A rotating disk 503 is provided below the second drive motor 506. A third drive motor 6 is provided below the middle of the rotating seat 5. A first transmission cylinder 8 is provided below the third drive motor 6. A second transmission rod 7 is provided on one side of the first transmission cylinder 8. Transmission discs 9 are provided on both sides of the first transmission cylinder 8 and the second transmission rod 7. Figures 1 to 3 The machine base 1 has a through-hole in the middle for inserting a metal rod, and the distance between the material hole and the side wall of the machine base 1 is equal in width and height. A protruding rod 105 is provided on one side of the connecting cylinder 103, and a material carrier 401 is sleeved on the protruding rod 105. A circular array of through-holes is provided around the material carrier 401. The hopper 4 is bucket-shaped, and a broken annular plate is provided at the bottom of the hopper 4. A metal rod inlet is provided at the connection between the annular plate and the hopper 4, and the opening width is slightly larger than the diameter of the metal rod. A through-groove with the same shape as the transmission groove 901 is provided on the other side of the connecting cylinder 103. Meanwhile, referring to… Figure 2 and Figure 10The push rod cylinder 3 is mounted above the extension platform 101 via a cylinder mounting seat. The first drive motor 2 is mounted on the inner end of the extension platform 101 via a motor mounting plate. A turntable 201 is mounted on the output end of the first drive motor 2. The outer wall of the turntable 201 is provided with rotating teeth. The bottom of the rotating seat 5 is provided with a semi-circular seat tooth 501. The seat tooth 501 meshes with the rotating teeth on the outer wall of the turntable 201 for transmission. The hopper 4 can hold metal rods. The opening between the hopper 4 and the ring plate allows only one metal rod to pass through at a time. After falling, the metal rods fall into the uppermost circular groove of the conveyor belt 401. The conveyor belt 401 rotates downwards under the balance of gravity. At this time, the metal rods will enter the circular grooves of the annular array one by one. After the pusher cylinder 3 pushes the metal rods to slide in the material channel connected to the material hole, the metal rods fall into the material channel. At the same time, the circular grooves on one side of the conveyor belt 401 are all equipped with metal rods, while the circular grooves on the other side are all hollow. Due to the gravity of the metal rods, the conveyor belt 401 will continue to rotate, so that the metal rods avoid collision with the material and achieve the effect of automated feeding.
[0029] In the embodiments, reference Figures 1 to 9The transmission disc 9 has concave arc-shaped transmission grooves 901 arranged in a circumferential array. The first transmission cylinder 8 and the second transmission rod 7 are arranged circumferentially within the transmission grooves 901. The inner wall of the base 1 has a mounting groove 104, and the transmission disc 9 is embedded in the mounting groove 104. The transmission disc 9 on the other side is mounted below the rotating seat 5 via a fixing plate 902. The second transmission rod 7 is located below the first transmission cylinder 8, and the outer wall of the first transmission cylinder 8 has a clockwise spiral groove 801. A transmission belt connecting groove is provided on one side of the first transmission cylinder 8. 803, the output end of the third drive motor 6 is fitted with a transmission belt 601, which is connected to the transmission belt connecting groove 803. A mounting hole 8-1 is provided in the middle of the first transmission cylinder 8, and a straight rod 802 is fixedly connected inside the mounting hole 8-1. Both sides of the straight rod 802 pass through the transmission grooves 901 of the transmission disc 9. The first transmission cylinder 8 is made of flexible material, and the transmission belt 601 is made of elastic material. There are three transmission grooves 901 arranged in a circular array on the transmission disc 9. The second transmission cylinder 8 is located at the top of the transmission disc 9. The transmission groove 901 is set with two first transmission rods 7, which are set in the transmission groove 901 below the second transmission cylinder 8. When the metal rod enters the material hole, the first drive motor 2 is energized to drive the turntable 201 to rotate. At the same time, the rotating seat 501 is rotated through the meshing seat teeth. After the rotating seat 5 rotates, it drives the transmission disk 9 connected to the bottom of the fixed plate 902 to rotate as well. This causes the two first transmission rods 7 and one transmission cylinder 8 embedded in the transmission groove 901 in the transmission disk 9 to move along the concave arc trajectory, so that the two first transmission rods 7 and one transmission cylinder 8 converge towards the material hole, achieving the clamping effect on the metal rod in the material hole. At the same time, the third drive motor 6 is energized to drive the transmission belt 601, causing the first transmission cylinder 8 to rotate as well. At this time, the flexible material of the first transmission cylinder comes into contact with the outer wall of the metal rod. The clockwise rotation of the spiral groove generates a forward force. After the first transmission cylinder 8 continues to rotate, the contact with the metal rod will cause the metal rod to move forward a certain distance, achieving the effect of controlling the precise movement of the metal rod, thereby further improving the accurate bending effect of the metal rod.
[0030] Furthermore, the first transmission cylinder 8 is made of flexible material, and the transmission belt 601 is made of elastic material. The flexible material of the first transmission cylinder 8 can increase the coefficient of friction with the metal rod, and the elastic material of the transmission belt 601 can prevent the transmission belt 601 from coming off when the first transmission cylinder 8 moves, thus improving the stability of the connection. Moreover, a straight rod 802 is fixed in the mounting hole 8-1 in the center of the first transmission cylinder 8. The two sides of the straight rod 802 are inserted into the transmission grooves 901 of the transmission discs 9. One of the transmission discs 9 is embedded in the mounting groove 104 on the middle side wall of the machine base 1, and the other transmission disc 9 is fixed to the lower end face of the rotating seat 5 by the fixing plate 902. The material part 401 is sleeved on the outer wall of the protruding rod 105.
[0031] Furthermore, the distance from the material hole to the top and sides of the machine base 1 is equal, so that the horizontal position of the bending head 505 relative to the material hole will not change when the rotating seat 5 rotates.
[0032] In the embodiments, reference Figure 4 The rotating base 5 is also provided with an extension plate 504 in the middle to further provide force relief to the rotating base, and the bottom of the rotating disk 503 is provided with a movable and embedded bending head 505. There are two bending heads 505, so that after the bending heads 505 are inserted into the gap between them, the rotating disk 503 rotates and can drive the inserted metal rod to perform bending work. After the metal rod reaches the outlet at the side end of the machine base 1, the second drive motor 506 in the seat 502 is energized to rotate the rotating disk 503 with the output end fixed. After the rotating disk 503 rotates, the two bending heads 505 inserted through it can bend the metal rod in the middle. At the same time, after the rotating disk 503 rotates, the movable bending head 505 will generate a force in the same direction as the metal rod begins to be bent, so that the contact surface of the metal rod will continue to change, thereby further reducing the probability of indentation on the metal rod.
[0033] Working principle: Metal rods can be placed in the hopper 4. The opening between the hopper 4 and the ring plate allows only one metal rod to pass through at a time. After the metal rod passes through the opening and falls downwards, it falls into the uppermost circular groove of the conveyor belt 401. The conveyor belt 401 rotates downwards under the balance of gravity. At this time, the metal rods will enter the circular grooves of the annular array one by one. After the pusher cylinder 3 pushes the metal rod to slide in the material channel connected to the material hole, the metal rod falls into the material channel. At the same time, the circular grooves on one side of the conveyor belt 401 are all equipped with metal rods, while the circular grooves on the other side are all hollow. The weight of the metal rod causes the material carrier 401 to rotate continuously, preventing collisions and achieving automated feeding. Once the metal rod enters the feeding hole, the first drive motor 2 is energized, rotating the turntable 201. Simultaneously, the meshing seat teeth 501 cause the rotating seat to rotate as well. The rotating seat 5 then rotates the transmission disc 9 connected below the fixed plate 902, causing the two first transmission rods 7 and one transmission cylinder 8 embedded in the transmission groove 901 within the transmission disc 9 to move along a concave arc trajectory. This brings the two first transmission rods 7 and one transmission cylinder 8 towards the feeding hole, clamping the metal rod inside. Simultaneously, the third drive motor 6 is energized, driving the transmission belt 601, causing the first transmission cylinder 8 to rotate. At this point, the flexible material of the first transmission cylinder contacts the outer wall of the metal rod. The clockwise rotation of the spiral groove generates a forward force. As the first transmission cylinder 8 continues to rotate, its contact with the metal rod causes the metal rod to move forward a certain distance, achieving precise control of the metal rod's movement and further improving the accurate bending of the metal rod. As a result, after the metal rod reaches the outlet of the machine base 1, the second drive motor 506 in the back seat 502 is energized, causing the fixed output disc 503 to rotate. After the disc 503 rotates, the two bending heads 505 bend the metal rod in the middle. At the same time, after the disc 503 rotates, the movable bending head 505 will generate a force in the same direction as the metal rod is gradually bent, so that the contact surface of the metal rod continues to change, thereby further reducing the probability of indentations on the metal rod.
