Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a cutting device for the production of electric sofa frames. Background Technology

[0002] The electric sofa frame is a core component ensuring the sofa's functionality and stability, mainly consisting of a support frame, drive assembly, connecting hinges, and C-shaped rails. The support frame bears the overall weight of the sofa and the user's pressure, maintaining the sofa's basic shape; the drive assembly provides power for angle adjustments, crucial for backrest tilting and footrest extension; and the connecting hinges connect the backrest, footrest, and main frame, ensuring smooth rotation and secure connection of all moving parts.

[0003] In electric sofa frames, C-shaped guide rails are a common structural design, playing a crucial role in the angle adjustment system. They are primarily used to enable multi-angle adjustments and smooth movement of components such as the backrest and footrest, allowing users to flexibly adjust to a comfortable position according to their needs, avoiding any jamming or wobbling during adjustment. C-shaped guide rails are typically formed by bending, a process that precisely shapes a C-shaped cross-section structure that meets design requirements, ensuring compatibility with other components and structural strength. However, in subsequent production and assembly, due to differences in the required length of C-shaped guide rails for different sizes of electric sofas, a cutting machine is needed to cut the C-shaped guide rails into segments. This ensures that the length accurately matches the overall assembly dimensions of the sofa frame, guaranteeing coordinated operation of all components and further improving the stability and smoothness of the electric sofa's adjustment.

[0004] Existing cutting equipment for electric sofa frames has significant shortcomings in its cutting process for C-shaped guide rails. Because the sidewalls of the C-shaped guide rails lack a dedicated support structure during cutting, the cutting force generated by the blade directly compresses the sidewalls without proper support or cushioning. This compression easily leads to bending and deformation of the sidewalls, affecting the assembly accuracy of the C-shaped guide rails with other components of the sofa frame. This can cause installation jams or abnormal fit gaps, and also reduces the stability of the C-shaped guide rail's adjustment function. Ultimately, the overall cutting effect is poor, failing to meet the production quality requirements of electric sofa frames. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for the production of electric sofa frames, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for producing electric sofa frames, comprising a cutting table, a support frame fixed to the bottom of the cutting table, and a cutting machine disposed at the top of the cutting table. A slit is formed through the middle of the cutting table. Two positioning beams are symmetrically fixedly installed on the outer sides of the top of the slit on the cutting table.

A fixing plate is fixedly installed on the outer side of the cutting table near one of the positioning beams. A cover support component is disposed at the top of the fixing plate. The conveying abutment component includes several drive rollers and a drive belt. The several drive rollers are equidistantly and rotatably installed inside the C-shaped mounting brackets. The drive belt is sleeved around the several drive rollers.

[0007] Furthermore, a control console is fixedly installed on the top side of the cutting table, a drive slide is fixedly installed on the top side of the cutting table near the cutting machine, and the bottom side of the cutting machine is fixedly installed on the top of the slider of the drive slide.

[0008] Furthermore, a drive motor is fixedly mounted on the outside of the C-shaped mounting bracket near one of the drive rollers, and the output end of the drive motor is coaxially fixed with one end of one of the drive rollers.

[0009] Furthermore, several friction blocks are fixedly installed at equal intervals on the outside of the drive belt.

[0010] Furthermore, the telescopic control component includes a liquid collection chamber and a first cylinder. The liquid collection chamber is located in the middle of the interior of the positioning beam. The first cylinder is vertically fixedly installed on the outside of the bottom end of the cutting table near the liquid collection chamber. The output end of the first cylinder is slidably installed inside the liquid collection chamber. A piston block is fixedly installed at the top of the output end of the first cylinder. The piston block and the inner wall of the liquid collection chamber are in a sliding seal connection.

[0011] Furthermore, the positioning beam has transversely through-holes on both sides of its inner edge. Two piston rods are symmetrically and slidably installed inside each of the through-holes. One end of each piston rod is fixedly installed on the outside of one side of the C-shaped mounting bracket. A liquid guiding channel is provided on the positioning beam between the through-hole and the liquid collecting chamber. One end of the liquid guiding channel is connected to the top of the liquid collecting chamber, and the other end of the liquid guiding channel is connected to the middle of the through-hole.

[0012] Furthermore, the correction assembly includes an electric telescopic rod and a double-sided rack. The electric telescopic rod is vertically fixedly installed on the outside of one side of the positioning beam. The double-sided rack is vertically fixed on the outside of the output end of the electric telescopic rod. A guide strip is fixedly installed on the side of the positioning beam near the double-sided rack. One side of the double-sided rack is vertically slidably engaged with the outside of one side of the guide strip. Two limiting gears are symmetrically meshed on both sides of the double-sided rack. A rotating rod is provided on one side of each limiting gear.

[0013] Furthermore, rotating seats are rotatably mounted through both ends of the rotating rod. One side of the rotating seat is fixedly connected to the side of the positioning beam near the bottom. One end of the rotating rod is fixedly mounted through the middle of the limiting gear on the corresponding side. A connecting plate is fixedly mounted on one side of the bottom of the rotating rod. A columnar rubber strip is fixedly mounted on the end of the connecting plate away from the rotating rod.

[0014] Furthermore, the cover support assembly includes a limiting groove and a limiting rotating shaft. The limiting groove is opened inside the top of the fixed plate, and the limiting rotating shaft is rotatably installed inside one side edge of the limiting groove. A drive gear is fixedly installed through the outside of one end of the limiting rotating shaft, and a drive rack is laterally meshed at the bottom end of the drive gear.

[0015] Furthermore, a second cylinder is fixedly mounted on the side of the fixed plate near the drive rack via a bracket. The output end of the second cylinder is fixedly connected to one side of the drive rack. A rotating plate is fixedly mounted on one side of the limiting shaft. A placement groove is provided at the top of the rotating plate, and a plastic cover is placed inside the placement groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By incorporating positioning beams on both sides of the cut, along with C-shaped mounting brackets and conveyor contact components, this cutting equipment provides reliable foundation positioning for the C-shaped guide rail during cutting. It establishes a stable support benchmark from both sides of the cutting area, effectively resisting the force generated by the cutting blade's compression, preventing bending deformation of the C-shaped guide rail sidewalls under stress, ensuring the structural accuracy and subsequent performance of the C-shaped guide rail after cutting, and avoiding deformation under stress. Simultaneously, the telescopic adjustment component allows for flexible expansion and fine-tuning of the C-shaped mounting brackets and conveyor contact components on both sides of the positioning beams. This adjusts the contact force and fit according to the actual specifications of the C-shaped guide rail, resulting in a more uniform and stable contact effect, avoiding insufficient local support. This design not only further enhances support reliability but also adapts to C-shaped guide rails of different sizes and specifications, significantly expanding the applicability of the device and reducing the hassle of replacing special tooling due to differences in C-shaped guide rail specifications. It also provides precise structural support for subsequent assembly processes.

[0018] 2. By setting up the correction component, the cutting equipment can form a stable resisting and expanding force on the concave sidewall of the C-shaped guide rail opening during use, effectively maintaining the vertical state of the sidewall and preventing deformation of the groove during processing or subsequent operations. This provides a precise structural foundation for subsequent installation processes, reduces the amount of adjustment work during installation, and prevents installation deviations or component damage caused by groove deformation. It ensures the overall structural stability and assembly quality of the C-shaped frame, and improves the reliability of product processing and assembly. At the same time, by setting up the cover support component, after the correction component is completed, a plastic cover is placed against the inside of one end of the corrected C-shaped guide rail. With the help of the embedded plastic cover, it fits tightly against the inner wall of the C-shaped guide rail to form effective support. This not only prevents the C-shaped guide rail from sagging or slightly deforming due to the lack of restraint at one end in subsequent processes (such as temporary storage and transfer), but also ensures precise cooperation with other components.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 6 A cutting device for producing electric sofa frames includes a cutting table 1, a support frame 35 fixed to the bottom of the cutting table 1, and a cutting machine 4 set at the top of the cutting table 1. A slit 2 is opened through the middle of the cutting table 1. Two positioning beams 6 are symmetrically fixed on the outside of the top of the cutting table 1 at the top of the slit 2. Two C-shaped mounting brackets 7 are symmetrically arranged on both sides of the top of each positioning beam 6. A conveying abutment component is arranged on one side of each C-shaped mounting bracket 7. A telescopic adjustment component is arranged inside each positioning beam 6. The conveying abutment component includes a plurality of drive rollers 8 and a drive belt 9. The plurality of drive rollers 8 are equidistantly and rotatably installed inside the C-shaped mounting brackets 7. The drive belt 9 is driven and sleeved on the outside of the plurality of drive rollers 8.

[0033] A control console 5 is fixedly installed on the top side of the cutting table 1. A drive slide 3 is fixedly installed on the top side of the cutting table 1 near the cutting machine 4. The bottom side of the cutting machine 4 is fixedly installed on the top of the slider of the drive slide 3.

[0034] A drive motor 10 is fixedly mounted on the outside of the C-shaped mounting bracket 7 near one of the drive rollers 8, and the output end of the drive motor 10 is coaxially fixed with one end of one of the drive rollers 8.

[0035] Several friction blocks 11 are fixedly installed at equal intervals on the outside of the drive belt 9.

[0036] The telescopic control assembly includes a liquid collection chamber 12 and a first cylinder 13. The liquid collection chamber 12 is located in the middle of the interior of the positioning beam 6. The first cylinder 13 is vertically fixedly installed on the outside of the bottom side of the cutting table 1 near the liquid collection chamber 12. The output end of the first cylinder 13 is slidably installed inside the liquid collection chamber 12. A piston block 14 is fixedly installed at the top of the output end of the first cylinder 13. The piston block 14 and the inner wall of the liquid collection chamber 12 are connected by a sliding seal.

[0037] The positioning beam 6 has horizontally penetrating through-holes 15 on both sides of its inner edge. Two piston rods 16 are symmetrically and slidingly sealed inside the through-holes 15. One end of each piston rod 16 is fixedly installed on the outside of one side of the C-shaped mounting bracket 7. A liquid guiding channel 17 is provided on the positioning beam 6 between the through-holes 15 and the liquid collecting chamber 12. One end of the liquid guiding channel 17 is connected to the top of the liquid collecting chamber 12, and the other end of the liquid guiding channel 17 is connected to the middle of the through-hole 15.

[0038] In this embodiment, when using the cutting equipment for producing electric sofa frames to cut C-shaped guide rails, the workflow unfolds step by step around the logic of "C-shaped guide rail conveying and positioning, support spacing adjustment, precise cutting, and finished product conveying." The various components work together to achieve deformation-resistant cutting. The specific principle is as follows:

[0039] First, after the equipment is started, the operator issues a work command through the control panel 5, starting the drive motor 10. The output of the drive motor 10 drives one of the drive rollers 8, which is coaxially fixed with it, to rotate. Since several drive rollers 8 are all rotatably mounted inside the C-shaped mounting frame 7, and the external transmission is equipped with a drive belt 9, the rotation of a single drive roller 8 will drive the other drive rollers 8 to rotate synchronously through the drive belt 9, forming a continuous conveying power. At this time, the C-shaped guide rail to be cut is placed between the drive belts 9 on both sides of the C-shaped mounting frame 7. The friction blocks 11 fixed at equal intervals on the outside of the drive belt 9 will increase the friction with the surface of the C-shaped guide rail, preventing slippage during the conveying process, and thus smoothly conveying the C-shaped guide rail to the slit 2 in the middle of the cutting table 1. At the same time, the positioning beams 6 on both sides of the slit 2 on the cutting table 1 will play a preliminary positioning role from both sides of the C-shaped guide rail, ensuring that the cutting position of the C-shaped guide rail is aligned with the slit 2.

[0040] Next, based on the actual specifications of the C-shaped guide rail to be cut, such as width and thickness, the telescopic adjustment component is controlled by the control console 5 to adjust the spacing of the C-shaped mounting brackets 7 on both sides, so that the conveying contact component can accurately fit against the side wall of the C-shaped guide rail to form support. Specifically, the first cylinder 13 in the telescopic control assembly receives a command and extends its output end upward, causing the piston block 14 fixed at its top to slide upward in the liquid collection chamber 12 inside the positioning beam 6. Under the pressure of the piston block 14, the hydraulic oil in the liquid collection chamber 12 flows through the liquid guiding channel 17 opened inside the positioning beam 6 to the limiting through holes 15 on both sides. The hydraulic oil entering the limiting through holes 15 will push the two piston rods 16 that are slidably sealed and installed in the limiting through holes 15 on both sides respectively. One end of each piston rod 16 is fixed to the outside of one side of the C-shaped mounting bracket 7. Therefore, the extension of the piston rod 16 will cause the C-shaped mounting brackets 7 on both sides to move laterally away from the center of the positioning beam 6 until the drive belt 9 is tightly attached to the two side walls of the C-shaped guide rail, forming a stable lateral support, and preventing the C-shaped guide rail from shifting or deforming due to force during subsequent cutting.

[0041] Subsequently, the cutting stage begins. Control console 5 activates the drive slide 3 at the top of the cutting table 1. The slider of the drive slide 3 drives the cutting machine 4, fixed at its top, to move smoothly along the length of the kerf 2. During this movement, the cutting machine 4 initiates its cutting function, cutting the C-shaped guide rail supported and fixed below by the conveyor contact assembly. The kerf 2 provides clearance for the cutting blade, preventing damage to the cutting table 1 itself. Throughout this process, the drive belts 9 on the C-shaped mounting brackets 7 remain in contact with the sidewalls of the C-shaped guide rail. On one hand, the friction blocks 11 prevent lateral displacement of the C-shaped guide rail during cutting; on the other hand, the resulting support force counteracts the pressure exerted by the cutting blade on the sidewalls of the C-shaped guide rail, fundamentally preventing bending deformation of the C-shaped guide rail sidewalls.

[0042] Finally, after the C-shaped guide rail is cut, the control console 5 first controls the cutting machine 4 to stop cutting and resets it via the drive slide 3. Then, it controls the output end of the first cylinder 13 to retract, causing the piston block 14 to slide downward in the liquid collection chamber 12. A negative pressure is formed in the liquid collection chamber 12, and the hydraulic oil in the limiting through hole 15 will flow back to the liquid collection chamber 12 through the liquid guide channel 17. The piston rod 16 then retracts and drives the C-shaped mounting bracket 7 to reset. At the same time, the drive motor 10 continues to drive the drive belt 9 to rotate, conveying the cut C-shaped guide rail out of the equipment from above the cut slit 2, completing one complete C-shaped guide rail cutting cycle.

[0043] Example 2: Please refer to Figure 7 - Figure 10 This embodiment further illustrates Example 1. Each positioning beam 6 has a correction component on one side of its exterior. A fixing plate 25 is fixedly installed on the exterior of the cutting table 1 near one of the positioning beams 6. A cover support component is provided on the top of the fixing plate 25.

[0044] The correction assembly includes an electric telescopic rod 18 and a double-sided rack 19. The electric telescopic rod 18 is vertically fixed on the outside of one side of the positioning beam 6. The double-sided rack 19 is vertically fixed on the outside of the output end of the electric telescopic rod 18. A guide strip 34 is fixedly installed on the side of the positioning beam 6 near the double-sided rack 19. One side of the double-sided rack 19 is vertically slidably engaged with the outside of one side of the guide strip 34. Two limiting gears 22 are symmetrically meshed on both sides of the double-sided rack 19. A rotating rod 21 is provided on one side of each limiting gear 22.

[0045] Rotating rod 21 has rotating seats 20 mounted on both ends of its external surface. One side of the rotating seat 20 is fixedly connected to the side of the positioning beam 6 near the bottom. One end of the rotating rod 21 is fixedly mounted on the middle of the corresponding limiting gear 22. A connecting plate 23 is fixedly mounted on one side of the bottom of the rotating rod 21. A columnar rubber strip 24 is fixedly mounted on the end of the connecting plate 23 away from the rotating rod 21.

[0046] The cover support assembly includes a limiting groove 26 and a limiting shaft 27. The limiting groove 26 is opened inside the top of the fixed plate 25. The limiting shaft 27 is rotatably installed inside one side edge of the limiting groove 26. A drive gear 28 is fixedly installed through the outside of one end of the limiting shaft 27. A drive rack 30 is laterally meshed at the bottom end of the drive gear 28.

[0047] A second cylinder 29 is fixedly installed on the side of the fixed plate 25 near the drive rack 30 by a bracket. The output end of the second cylinder 29 is fixedly connected to one side of the drive rack 30. A rotating plate 31 is fixedly installed on one side of the limiting shaft 27. A placement groove 32 is opened at the top of the rotating plate 31, and a plastic cover 33 is placed inside the placement groove 32.

[0048] In this embodiment, Embodiment Two adds a correction component and a cover support component to Embodiment One, further enhancing the accuracy assurance and subsequent protection during C-shaped guide rail cutting. Its workflow connects to the "C-shaped guide rail conveying positioning and support spacing adjustment" step in Embodiment One. The specific principle is as follows:

[0049] First, in Embodiment 1, after the C-shaped guide rail has been conveyed to the top of the cut slit 2 by the conveying and contacting component, and the telescopic adjustment component drives the C-shaped mounting bracket 7 to form lateral support, the control console 5 will simultaneously activate the correction component on one side of the positioning beam 6 to precisely correct and reinforce the concave sidewall of the opening end of the C-shaped guide rail. The operation logic of the correction component is as follows: The control console 5 sends a command to the electric telescopic rod 18, and the output end of the electric telescopic rod 18 extends vertically downward, driving the double-sided rack 19 fixed at its top to move downward synchronously. Since the positioning beam 6 has a guide strip 34 fixed on one side near the double-sided rack 19, and one side of the double-sided rack 19 is vertically slidably engaged with the outside of the guide strip 34, the guide strip 34 can restrict the movement direction of the double-sided rack 19, preventing it from shifting laterally during the descent and ascent, and ensuring stable meshing transmission.

[0050] As the double-sided rack 19 moves downward, the two limiting gears 22 that are symmetrically meshed on both sides will be driven to rotate synchronously. The rotation of the limiting gears 22 will drive the rotating rod 21 to rotate synchronously inside the rotating seat 20. When the rotating rod 21 rotates, the connecting plate 23 will drive the columnar rubber strip 24 to flip towards the concave side wall of the C-shaped guide rail opening, until the columnar rubber strip 24 is tightly against the concave side wall of the C-shaped guide rail.

[0051] Due to the synchronous rotation of the limiting gears 22 on both sides and the synchronous flipping of the connecting plate 23, the columnar rubber strips 24 on both sides will apply a uniform resisting and expanding force to the concave side wall of the C-shaped guide rail. On the one hand, it can correct the slight verticality deviation of the C-shaped guide rail caused by the previous processing or transportation, and ensure that the side wall remains vertical. On the other hand, it can further offset the squeezing force of the cutting blade on the side wall of the C-shaped guide rail during the subsequent cutting process, and avoid the deformation of the groove. It provides double protection for cutting accuracy and subsequent assembly (the columnar rubber strips 24 are made of elastic rubber material, which can provide support while avoiding scratching the inner wall of the C-shaped guide rail).

[0052] After the corrective component completes the resistance expansion and the cutting machine 4 completes the C-shaped guide rail cutting according to the process of Embodiment 1, the control console 5 will start the cover support component to support and protect one end of the cut C-shaped guide rail, preventing the C-shaped guide rail from sagging and deforming due to the lack of restraint at one end during subsequent transportation or temporary storage. The working principle of the cover support component is as follows: The control console 5 sends a command to the second cylinder 29, and the output end of the second cylinder 29 extends laterally, driving the drive rack 30 fixed at its top to move synchronously. The movement of the drive rack 30 will drive the meshing drive gear 28 to rotate, thereby driving the limiting rotating shaft 27 fixed to the drive gear 28 to rotate inside one edge of the limiting groove 26. When the limiting rotating shaft 27 rotates, the rotating plate 31 will flip towards one end of the C-shaped guide rail. The top of the rotating plate 31 has a placement groove 32, and a plastic cover 33 is pre-placed inside the placement groove 32. When the rotating plate 31 flips... When aligned with the C-shaped guide rail end, the plastic cover 33 will be pushed by the rotating plate 31 and embedded into the interior of one end of the C-shaped guide rail. The outer wall of the plastic cover 33 is tightly fitted with the inner wall of the C-shaped guide rail, forming a stable internal support. This can effectively prevent the C-shaped guide rail from sagging or slightly deforming due to the lack of restraint at one end during the transfer and temporary storage after cutting. At the same time, the material of the plastic cover 33 can avoid scratching the inner wall of the C-shaped guide rail, thus preserving a good structural foundation for the subsequent precise assembly with other parts of the sofa frame. In addition, an existing feeding device can be installed on one side of the cutting table 1 to transport and place the plastic cover 33.
