Description

Technical Field

[0001] This invention relates to the field of bamboo product processing technology, and in particular to an oval bamboo ring processing device. Background Technology

[0002] In the bamboo product processing industry, oval bamboo rings are core components of bamboo lamps, furniture and other products, and their processing precision and forming quality directly affect the quality of the final product.

[0003] In the existing technology, the pressure structure of the elliptical bamboo ring processing equipment is still in the early stages. The design is unreasonable, the pressure process is rigid and the force is uneven. The pressure applied to the softened bamboo cannot be evenly distributed, which makes the bamboo very prone to cracking and deformation during the bending and forming process. This seriously affects the finished product qualification rate of the elliptical bamboo ring and increases production loss and processing costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an elliptical bamboo ring processing device, which solves the problems mentioned in the background art of traditional bamboo ring processing where the pressure is too rigid and the bamboo is prone to cracking and deformation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An elliptical bamboo ring processing device includes a support frame and a support plate fixed thereon, wherein a pressure application component is provided on the side wall of the support plate; The pressure application assembly includes multiple fixed frames, each fixedly connected to one side of a support plate. Each fixed frame has a slidingly fitted arc-shaped component inside. A first cylinder is fixedly connected to the end of each fixed frame. The output end of each first cylinder is fixedly connected to the side wall of the arc-shaped component at a corresponding position. A mold core is provided on one side of the support plate. Multiple fixed rods are fixedly connected to the other side of the support plate. A fixed plate is fixedly connected to the ends of the multiple fixed rods. A connecting plate is slidingly fitted to the outer wall of the multiple fixed rods. Multiple sliding rods are fixedly connected to the side wall of the connecting plate. Each sliding rod is slidingly fitted inside the support plate, with one end fixedly connected to the side wall of the mold core. A second cylinder is fixedly connected to the side wall of the fixed plate, with the output end of the second cylinder fixedly connected to the side wall of the connecting plate. A positioning assembly is provided on the outer wall of the fixed frame.

[0006] Furthermore, the positioning component includes a positioning baffle, a dovetail slider, and a connecting slider. The dovetail slider is fixedly connected to one end of the positioning baffle, and the connecting slider is fixedly connected to the other end of the positioning baffle.

[0007] Furthermore, one of the fixing frames has a dovetail groove inside, and the dovetail slider slides within the dovetail groove.

[0008] Furthermore, a connecting groove is provided inside the fixing frame at the corresponding position, and the connecting slider slides within the connecting groove.

[0009] Furthermore, an arc-shaped block is slidably fitted inside the connecting groove, and an arc-shaped groove is opened inside the connecting slider, with the arc-shaped block and the arc-shaped groove engaging with each other.

[0010] Furthermore, a guide rod is fixedly connected to the side wall of the arc-shaped block, and the guide rod is slidably fitted in the corresponding fixed frame, with a spring sleeved on the outer wall of the guide rod.

[0011] Compared with existing technologies, the advantages of this invention are: 1. By setting up multiple sets of first cylinders to drive the arc-shaped parts to move towards each other to complete the lateral uniform pressure, and cooperating with the second cylinder to drive the mold core to complete the elliptical shaping, the softened bamboo can be smoothly and flexibly pressed and shaped. This ensures that the bamboo is subjected to uniform force during the bending and shaping process and is not prone to cracking. It solves the problems of stiff pressure and easy cracking and deformation of bamboo in traditional bamboo ring processing, and improves the qualified rate of elliptical bamboo ring finished products.

[0012] 2: By assembling positioning components on the fixed frame, the positioning baffle can be quickly disassembled and positioned using dovetail sliders and connecting sliders. Combined with guide rods and springs to form elastic limits, the bamboo joint position can be precisely limited and the joint gap can be controlled within the standard range. This achieves precise alignment and limit at the bamboo ring joint, avoiding the problems of bamboo joint misalignment and excessive joint gap that are difficult to control, and ensuring the appearance quality and dimensional accuracy of the finished product.

[0015] Reference Figures 1-5 An elliptical bamboo ring processing device includes a support frame 1 and a support plate 2 fixed on its surface. The support plate 2 is provided with a pressure component 3 on its side wall. The support frame 1 is used to support all working components of the whole device, and plays the role of overall support and stability, so as to achieve the effect of smooth and stable operation of the device. The support plate 2 works with the support frame 1 to complete the regular arrangement of various forming components, so as to achieve the effect of centralized layout of processing structure and reduction of equipment space occupation. The pressure application component 3 includes multiple fixed frames 301, each fixedly connected to one side of the support plate 2. The fixed frames 301 are used to limit the sliding trajectory and installation position of the arc-shaped component 303 to ensure precise alignment of the pressing action. Each fixed frame 301 has an arc-shaped component 303 slidingly fitted inside. The arc-shaped component 303 is used to conform to the outer surface of the bamboo to complete the extrusion and shaping, achieving the effect of regularizing the curvature of the bamboo. Each fixed frame 301 has a first cylinder 302 fixedly connected to its end. The first cylinder 302 can be an SC32×50 type double-acting cylinder. The first cylinder 302 is used to provide a power source for the translation and pushing of the arc-shaped component 303, achieving the effect of uniform speed pushing to complete the lateral pressing. The output end of each first cylinder 302 is fixedly connected to the side wall of the arc-shaped component 303 at the corresponding position. The output end of the first cylinder 302 cooperates with the arc-shaped component 303 to perform synchronous linear pushing motion, achieving the effect of multi-directional synchronous extrusion of the bamboo.

[0016] A mold core 304 is provided on one side of the support plate 2. The mold core 304 is used to conform to the inner side of the bamboo to form a shaping reference, thereby limiting the internal forming size of the elliptical bamboo ring. Multiple fixing rods 307 are fixedly connected to the other side of the support plate 2. The fixing rods 307 are used to limit the sliding path of the connecting plate 306 to avoid displacement. The ends of the multiple fixing rods 307 are fixedly connected to fixing plates 308. The fixing plates 308 are used to fix and install the second cylinder 309 to stabilize the power installation point. The outer walls of the multiple fixing rods 307 are slidably fitted with connecting plates 306. The connecting plates 306 are used to link multiple sets of sliding rods 305 to move synchronously, thereby achieving uniform power transmission. Multiple sliding rods 305 are fixedly connected to the side wall of the connecting plate 306. The multiple sliding rods 305 are all slidably fitted inside the support plate 2. The sliding rods 305 cooperate with the support plate 2 to perform back-and-forth sliding motion, thereby smoothly driving the mold core 304 to adjust its position. One end of each of the multiple sliding rods 305 is fixedly connected to the side wall of the mold core 304.

[0017] A second cylinder 309 is fixedly connected to the side wall of the fixed plate 308. The second cylinder 309 can be an SC40×75 type double-acting cylinder. The second cylinder 309 is used to provide driving force for adjusting the position of the mold core 304, so as to achieve the effect of flexibly adjusting the size of the inner diameter of the mold. The output end of the second cylinder 309 is fixedly connected to the side wall of the connecting plate 306. The output end of the second cylinder 309 cooperates with the connecting plate 306 to perform horizontal pushing and pulling movements, so as to quickly complete the mold core position switching. A positioning component 4 is provided on the outer wall of the fixed frame 301.

[0018] The positioning component 4 is composed of a positioning baffle 401, a dovetail slider 402, and a connecting slider 403, achieving the effect of quickly assembling and positioning the workpiece. The dovetail slider 402 is fixedly connected to one end of the positioning baffle 401, and the connecting slider 403 is fixedly connected to the other end of the positioning baffle 401. One of the fixing brackets 301 has a dovetail groove 404 inside. The dovetail slider 402 is used to embed into the dovetail groove 404 to complete the unilateral positioning and guidance, thereby preventing the positioning baffle 401 from shifting to one side. The dovetail slider 402 slides and engages in the dovetail groove 404, and the dovetail slider 402 and the dovetail groove 404 perform vertical sliding engagement movements, thereby achieving the effect of conveniently completing unilateral assembly and positioning.

[0019] The corresponding fixing bracket 301 has a connecting groove 405 inside. The connecting groove 405 is used to accommodate the connecting slider 403 for alignment and installation, achieving the effect of reserving space for limiting assembly. The connecting slider 403 slides within the connecting groove 405. An arc-shaped block 407 slides within the connecting groove 405. An arc-shaped groove 406 is provided inside the connecting slider 403. The arc-shaped groove 406 is used to engage and lock the arc-shaped block 407, achieving the effect of locking and fixing the other side of the positioning baffle 401. As a result, the arc-shaped block 407 and the arc-shaped groove 406 engage with each other. A guide rod 408 is fixedly connected to the side wall of the arc-shaped block 407. The guide rod 408 is used to limit the range of motion of the arc-shaped block 407 to ensure smooth engagement. The guide rod 408 is slidably fitted in the corresponding fixed frame 301. A spring 409 is sleeved on the outer wall of the guide rod 408. The spring 409 is used to provide elastic clamping force for the arc-shaped block 407 to achieve automatic engagement and locking, while facilitating disassembly and separation by external force.

[0020] The elastic clamping force of the spring (409) ensures that the arc block (407) is always in pre-tight contact with the connecting slider (403), thereby automatically compensating for the slight deformation of the bamboo end during the pressure application process and ensuring uniform joint gap.

[0021] In this invention, during use, the pre-treated and softened bamboo is first placed on the outside of the mold core 304 to complete the initial placement of the workpiece. During operation, the second cylinder 309 on the fixing plate 308 is activated first. The second cylinder 309 pushes the connecting plate 306 to slide smoothly along the surface of the fixing rod 307. The connecting plate 306 drives multiple sliding rods 305 to move synchronously. The sliding rods 305 pass through the support plate 2 and drive the mold core 304 to complete the position adjustment, thereby adjusting the inner diameter of the mold and adapting to the processing needs of oval bamboo rings of different sizes. After the mold core is positioned, the first cylinders 302 on multiple sets of fixing frames 301 are started simultaneously. The output end of the first cylinder 302 pushes the arc-shaped part 303 to slide smoothly along the inside of the fixing frame 301. Multiple sets of arc-shaped parts 303 move towards the mold core 304 simultaneously, and push the bamboo material evenly from multiple directions, so that the bamboo material fits the outer wall of the mold core 304 to complete the bending and shaping. The multi-directional synchronous pressure method makes the bamboo material uniformly stressed, avoiding cracking, twisting and deformation caused by uneven pressure, and improving the finished product qualification rate.

[0022] During the bamboo joining and forming process, the staff can assemble the positioning component 4 according to the processing requirements. The dovetail slider 402 at one end of the positioning baffle 401 is inserted into the dovetail groove 404 to complete the limiting. Then, the connecting slider 403 at the other end is placed into the connecting groove 405, so that the arc groove 406 and the arc block 407 are locked together. At the same time, the guide rod 408 and the outer wall spring 409 form an elastic pressing state, which can stably limit the positioning baffle 401. By relying on the positioning baffle 401 to block and limit the two ends of the bamboo, the bamboo joining gap is precisely controlled to prevent the bamboo from being misaligned. When there is no need to limit the joint gap, the positioning baffle 401 can be pulled outward directly to overcome the elastic force of the spring 409 to complete the quick disassembly. The equipment can then perform ordinary arc bamboo processing normally. After processing, all cylinders are reset in sequence, the arc part 303 and the mold core 304 are separated, and the staff can take out the processed elliptical bamboo ring.

[0023] In operation, this invention first uses a second cylinder to push the mold core to expand the inner diameter of the bamboo ring, forming a skeletal support. Then, multiple sets of first cylinders simultaneously push the arc-shaped component to tightly grip the bamboo from the outside. This bidirectional stress balance mechanism, which supports from the inside out and compresses from the outside in, effectively avoids cracks in the bamboo caused by excessive force on one side.

[0024] Traditional positioning methods often rely on rigid fixation, which can easily lead to misalignment at both ends of the bamboo when bent due to stress rebound. The positioning baffle of this invention uses a dovetail slider for guidance and utilizes spring force to keep the arc-shaped block firmly pressed against the arc-shaped groove. This elastic limiting structure allows the bamboo to release stress within a small range while ensuring the flatness of the mating surfaces at both ends, solving the problem of 'tilting under pressure and crumbling when loosened'. Example

[0025] 1. Workpiece pre-positioning and positioning (initial state) Action description: Place the softened bamboo strips (such as steaming or microwave softening) on ​​the outside of the mold core 304.

[0026] Positioning component intervention: The staff installed the positioning baffle 401 into place. Specifically: Insert the dovetail slider 402 at one end of the positioning baffle 401 into the dovetail groove 404 of the fixing frame 301; Push the connecting slider 403 at the other end into the connecting groove 405. At this time, the arc groove 406 inside the connecting slider will squeeze the arc block 407.

[0027] Key point: Under the elastic force of spring 409, arc block 407 automatically resets and locks into arc groove 406, realizing the rapid locking of positioning baffle.

[0028] Technical effect: The positioning baffle 401 restricts the position of both ends of the bamboo. Due to the presence of the spring 409, the positioning is not completely rigid and locked, but allows the bamboo to release internal stress within a small range, preventing misalignment of the bamboo due to springback.

[0029] 2. Internal support stage (mold core action) Action Description: The control system activates the second cylinder 309. The second cylinder 309 pushes the connecting plate 306 to slide along the fixed rod 307, thereby driving the mold core 304 forward until the mold core 304 abuts against the inner wall of the bamboo material.

[0030] Key: At this stage, the mold core 304 applies an outward supporting force to the inner wall of the bamboo, initially expanding the bamboo to the major or minor axis dimension of the target ellipse (depending on the installation direction).

[0031] Technical effect: The "first support" action pre-imposes an outward tension on the bamboo, changing the stress distribution inside the bamboo and preparing it for subsequent lateral bending.

[0032] 3. External clamping and shaping stage (pressure component action) Action description: After the mold core (304) completes the shaping, multiple sets of first cylinders (302) start synchronously.

[0033] The first cylinder (302) pushes the arc-shaped part (303) to move along the fixed frame (301) toward the central axis.

[0034] Multiple curved pieces (303) simultaneously compress the outer side of the bamboo material from different angles.

[0035] Key logic: This is a process of "multi-point synchronous pressure". Due to the internal support of the mold core (304) and the external traction of the arc-shaped part (303), the bamboo material undergoes bending deformation under bidirectional force.

[0036] Technical effect: This synergistic "internal and external pressure" mechanism ensures more balanced stress on the stretched and compressed surfaces of the bamboo. Compared to traditional equipment that applies pressure from only one side, this equipment effectively prevents excessive stretching and cracking on the outer side of the bamboo, or excessive compression and wrinkling on the inner side.

[0037] 4. Pressure holding and resetting (finished product removal) Action description: Maintain pressure for a period of time (pressure holding) to shape the bamboo fibers into the target elliptical shape. Then, the first cylinder (302) retracts, and the arc-shaped part (303) detaches from the bamboo; the second cylinder (309) retracts, and the mold core (304) retracts.

[0038] Disassembly: The worker pulls the positioning baffle (401) outward to overcome the elastic force of the spring (409) so that the arc block (407) is disengaged from the arc groove (406) and the processed elliptical bamboo ring can be taken out.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
