Technical Field
[0001] This utility model relates to the field of bending and shaping machine technology, and in particular to a bending and shaping machine for processing environmentally friendly dining chairs. Background Technology
[0002] In the field of eco-friendly dining chair manufacturing, bending and shaping machines are key equipment to ensure smooth production. As environmental awareness grows, the market demand for eco-friendly dining chairs is increasing, placing higher demands on the performance of processing equipment. Bending and shaping machines need to precisely and efficiently bend tubing of various materials and specifications to meet diverse dining chair design requirements.
[0003] Currently, in the processing of eco-friendly dining chairs, traditional bending and shaping machines typically employ relatively fixed mold structures. These molds, with specific shapes and sizes, fit tightly against the surface of the tubing, using mechanical pressure to bend the tubing to a predetermined angle. Their working principle is primarily based on the friction between the mold and the tubing, as well as the rigid constraint of the mold itself, causing the tubing to undergo plastic deformation under pressure, thereby achieving the purpose of bending and shaping.
[0004] However, traditional bending and shaping machines have significant limitations. Because they rely on molds of specific sizes to position the tube surface, a single mold can only be used for positioning tubes of the same size. In actual environmentally friendly dining chair processing, the tube specifications used are diverse, and different dining chair styles require tubes of different diameters and wall thicknesses. When processing tubes of different sizes, traditional bending and shaping machines often require frequent mold changes, which is cumbersome and time-consuming, greatly affecting production efficiency and making it difficult to adapt to diverse tube processing needs. This severely restricts the applicability of the equipment in environmentally friendly dining chair processing. Therefore, a bending and shaping machine for environmentally friendly dining chair processing is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a bending and shaping machine for processing environmentally friendly dining chairs, which aims to improve the problem that traditional bending machines usually use molds to position the surface of the tube, but the molds can only position tubes of the same size and are difficult to adapt to different tubes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A bending and shaping machine for processing environmentally friendly dining chairs includes a bending machine, a support base fixedly connected to one side of the bending machine, a control machine rotatably connected to the outer wall of the support base, positioning components provided on the outer walls of both the support base and the control machine, and a stabilizing component provided on the outer wall of the bending machine.
[0008] The positioning assembly includes two connecting blocks 1. The outer walls of the two connecting blocks 1 are respectively fixedly connected to the outer walls of the support base and the control machine. Each connecting block 1 has a rotating shaft rotatably connected to both sides inside. Each rotating shaft has a worm gear and a connecting block 2 fixedly connected to its outer wall. Each connecting block 1 and connecting block 2 has a protective pad fixedly connected to one side. Each connecting block 1 has a fixing frame 1 and a fixing frame 2 fixedly connected to one side. A worm gear is rotatably connected between the fixing frame 1 and the fixing frame 2. Each worm gear has a handle fixedly connected to one end.
[0009] As a further description of the above technical solution:
[0010] The stabilizing component includes multiple arc-shaped rubber pads located at the top of the bending machine, and a connecting frame is fixedly connected to the bottom of the bending machine.
[0011] As a further description of the above technical solution:
[0012] A motor is fixedly connected inside the connecting frame, and a connecting plate is fixedly connected to the output end of the motor.
[0013] As a further description of the above technical solution:
[0014] Both sides of the connecting plate are rotatably connected to transmission plates, and each transmission plate is rotatably connected to a rotating bar inside.
[0015] As a further description of the above technical solution:
[0016] Each of the rotating bars is fixedly connected to a slide at its bottom, and multiple slides are located on top of the connecting frame.
[0017] As a further description of the above technical solution:
[0018] Each of the slide blocks has a fixed block slidably connected to both sides inside, and the bottom of the multiple fixed blocks is fixedly connected to the top of the connecting frame.
[0019] As a further description of the above technical solution:
[0020] Each of the slide blocks is fixedly connected to a second connecting plate on its top, and each of the second connecting plates is fixedly connected to a clamping plate on its opposite side.
[0021] As a further description of the above technical solution:
[0022] Each of the clamps has an arc-shaped rubber pad fixedly connected to its inner wall, and the curvature of the inner wall of the arc-shaped rubber pad is consistent with the curvature of the outer wall of the pipe.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by rotating the handle, the two connecting blocks on both sides are rotated in opposite directions, and the angle of the connecting blocks is fixed by the self-locking property between the worm gear and the worm, the positioning effect of pipes of different sizes is achieved. This solves the problem that traditional bending machines usually use molds to position the surface of pipes, but the molds can only position pipes of the same size and are difficult to adapt to different pipes, thus enhancing the applicability of the equipment.
[0025] 2. In this utility model, the pipe is clamped and fixed on both sides by the clamping plates on both sides, and the vibration force on the surface of the pipe is relieved by the arc-shaped rubber pad, which achieves the effect of fixing the position of the pipe. This solves the problem that the surface of the pipe is prone to shaking or even displacement during the bending process of the pipe by the traditional bending machine, which affects the subsequent bending accuracy. This enhances the fixing effect of the equipment on the position of the pipe. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2An embodiment of this utility model is provided: a bending and shaping machine for processing environmentally friendly dining chairs, including a bending machine 1, a support base 2 fixedly connected to one side of the bending machine 1, a control machine 3 rotatably connected to the outer wall of the support base 2, positioning components are provided on the outer walls of both the support base 2 and the control machine 3, and a stabilizing component is provided on the outer wall of the bending machine 1.
[0033] The positioning assembly includes two connecting blocks 5, whose outer walls are fixedly connected to the outer walls of the support base 2 and the control mechanism 3, respectively. The function of the connecting blocks 5 is to connect the support base 2 and the control mechanism 3 and transmit force. Each connecting block 5 has a rotating shaft 7 rotatably connected to both sides inside. The rotating shaft 7 provides rotational support and transmits torque. Each rotating shaft 7 has a worm gear 8 and a connecting block 6 fixedly connected to its outer wall. The worm gear 8 meshes with a worm 9 to achieve transmission. The connecting block 6 clamps the pipe. Protective pads 21 are fixedly connected to one side of each connecting block 5 and connecting block 6. The protective pads 21 are used to prevent damage to the surface of the pipe. Each connecting block 5 is fixedly connected to one side of each fixing bracket 10 and fixing bracket 21. The fixing bracket 10 and fixing bracket 211 are used to support the worm 9. The worm 9 is rotatably connected between the fixing bracket 10 and fixing bracket 21. The worm 9 is used to drive the worm wheel 8 to rotate. Each worm 9 is fixedly connected to one end of each worm 9. The handle 12 is used to facilitate manual operation.
[0034] Specifically, during the extrusion process of the pipe, the handle 12 is rotated, which drives the worm 9 to rotate. The rotation of the worm 9 transmits power through the meshing relationship between the worm 9 and the worm wheel 8, pushing the worm wheels 8 on both sides to rotate in opposite directions. While the worm wheels 8 are rotating, they also drive the connecting block 6 to rotate in opposite directions through the rotating shaft 7, so that the distance between the connecting blocks 6 on both sides is gradually adjusted to a position that matches the outer wall of the pipe. After the adjustment is in place, the self-locking property between the worm 9 and the worm wheel 8 can keep the angle of the connecting block 6 fixed, preventing displacement during the extrusion process. Ultimately, this allows the equipment to adapt to the processing needs of pipes of different diameters, enhancing the applicability of the equipment.
[0035] Reference Figure 1 and Figure 3The stabilizing component includes multiple arc-shaped rubber pads 20 located at the top of the bending machine 1. The arc-shaped rubber pads 20 contact the pipe surface and provide cushioning protection. A connecting frame 4 is fixedly connected to the bottom of the bending machine 1. The connecting frame 4 supports and fixes the entire stabilizing component. A motor 13 is fixedly connected inside the connecting frame 4, providing power to the clamping mechanism. A connecting plate 14 is fixedly connected to the output end of the motor 13, transmitting the rotational motion of the motor 13 to the transmission mechanism. Transmission plates 15 are rotatably connected to both sides of the connecting plate 14, converting the rotational motion into linear motion. A rotating bar 22 is rotatably connected inside each transmission plate 15, connecting the transmission plate 15 and the slide 16 and transmitting motion. Each rotating bar 22 has a bottom... Each component is fixedly connected to a slide block 16. The function of the slide block 16 is to drive the clamping mechanism to move along a fixed track. Multiple slide blocks 16 are located on the top of the connecting frame 4. Each slide block 16 has a fixed block 17 slidably connected to both sides inside. The function of the fixed block 17 is to limit the movement trajectory of the slide block 16. The bottom of multiple fixed blocks 17 is fixedly connected to the top of the connecting frame 4. Each slide block 16 has a connecting plate 28 fixedly connected to the top. The function of the connecting plate 28 is to connect the slide block 16 and the clamping mechanism. Each connecting plate 28 has a clamping plate 19 fixedly connected to the opposite side. The function of the clamping plate 19 is to directly clamp and fix the pipe. Each clamping plate 19 has an arc-shaped rubber pad 20 fixedly connected to the inner wall. The function of the arc-shaped rubber pad 20 is to protect the surface of the pipe and provide cushioning. The arc of the inner wall of the arc-shaped rubber pad 20 is consistent with the arc of the outer wall of the pipe to ensure a tight contact.
[0036] Specifically, during the pipe positioning process, motor 13 is started, and motor 13 begins to run and outputs rotational power. The output end of motor 13 drives connecting plate 14 to rotate. Connecting plate 14 drives transmission plates 15 on both sides to rotate synchronously. While rotating, transmission plates 15 drive slide blocks 16 on both sides to slide in the opposite direction on the outer wall of fixing block 17 through rotating bar 22. Fixing block 17 precisely limits the movement direction of slide blocks 16 to ensure that slide blocks 16 move along the predetermined trajectory without deviation. During the movement, slide blocks 16 drive connecting plate 18 and its connected clamping plate 19 to approach the pipe surface. When clamping plate 19 contacts the pipe surface, arc-shaped rubber pad 20 first contacts the pipe. As the clamping force increases, clamping plate 19 applies a uniform clamping force to the pipe surface, firmly fixing the pipe. In the subsequent bending process, arc-shaped rubber pad 20 can effectively absorb and buffer the vibration and shaking generated by the pipe, maintain the stability of the pipe during the bending process, avoid the decrease in bending accuracy caused by vibration, and improve work efficiency and clamping accuracy.
[0037] Working principle: During the extrusion of the pipe, rotating the handle 12 drives the worm 9 to rotate. The meshing relationship between the worm 9 and the worm wheel 8 drives the worm wheels 8 on both sides to rotate in opposite directions. While the worm wheels 8 are rotating, they drive the connecting block 6 to rotate in opposite directions through the rotating shaft 7, so that the distance between the connecting blocks 6 on both sides matches the outer wall of the pipe. Furthermore, the self-locking property between the worm 9 and the worm wheel 8 fixes the angle of the connecting blocks 6 on both sides, enhancing the applicability of the equipment.
[0038] During the process of fixing the position of the pipe, the motor 13 is started, and the output end of the motor 13 drives the connecting plate 14 to rotate, thereby driving the transmission plate 15 to rotate synchronously. While rotating, the transmission plate 15 drives the slides 16 on both sides to slide in the opposite direction on the outer wall of the fixing block 17 through the rotating bar 22. The fixing block 17 limits the movement direction of the slides 16 to prevent the slides 16 from deviating from the predetermined trajectory while moving. While moving, the slides 16 drive the clamping plate 19 on one side of the connecting plate 18 to clamp and fix the surface of the pipe, thus fixing the surface of the pipe. At the same time, the arc-shaped rubber pad 20 is used to buffer the shaking force generated during the bending process of the pipe, thereby enhancing the stability of the pipe during the bending process.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
