Description

Technical Field

[0001] This utility model relates to a cutting device for producing iron frames, and more particularly to a cutting device with a protective structure for producing sofa iron frames, which is applied in the field of cutting devices. Background Technology

[0002] Cutting equipment refers to machinery or tools used to divide, cut, or slit materials. It is widely used in various fields such as industrial manufacturing, construction, metal processing, electronics, and medical applications. Based on different cutting principles, materials, and application scenarios, cutting equipment can be divided into several types. Sofa frame cutting devices are specialized equipment designed specifically for cutting strip-shaped iron frames in sofa frame production.

[0003] Chinese patent CN203992592U discloses a metal pipe cutting device, including a cutting machine, a frame one, and a frame two. The frame one includes two right-angled iron frames on the left and right and two crossbeams. The upper and lower ends of the two iron frames are connected by the crossbeams. The frame two includes a square frame and a pipe-laying frame. The frame has upper and lower pins at the four opposite corners. It is a metal pipe cutting device with simple structure and convenient use, which can cut multiple pipes side by side or stacked.

[0004] Chinese patent CN208289099U discloses an automatic steel pipe cutting device, including a working platform. First grooves are formed on both sides of the working platform, and first iron frames are provided on both sides of the right side of the upper surface of the working platform. A stainless steel plate is fixedly connected between the upper ends of the two sets of first iron frames. A cylinder is installed on the upper surface of the stainless steel plate. This invention facilitates adjustment of the required cutting length of the steel pipe, results in more precise cutting, automates the steel pipe cutting process, improves work efficiency, and provides protection for workers.

[0005] Traditional equipment often has a fixed protective structure that cannot be adjusted synchronously with the movement of the cutting components. This causes metal debris to easily fly out of the gaps during cutting, posing a safety threat to operators and potentially affecting the accuracy of subsequent processing due to debris adhering to the equipment surface. The limited range of protection also results in blind spots of protection when cutting strip-shaped iron frames of different specifications, increasing the risk of production accidents. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the protective structure of traditional devices is mostly fixed and cannot be adjusted synchronously with the movement of the cutting components. This causes metal chips to easily fly out of the gaps during cutting, which not only poses a safety threat to the operators, but may also affect the subsequent processing accuracy due to the chips adhering to the equipment surface. The limited protection range often results in localized blind spots when cutting strip-shaped iron frames of different specifications, increasing the risk of production accidents.

[0007] To solve the above problems, this utility model provides a cutting device for producing sofa iron frames with a protective structure, including a cutting equipment component 1. A linkage adaptive protection component 2 is provided at the upper end of the cutting equipment component 1, and a fine-fitting component 3 is provided in the linkage adaptive protection component 2. A dust-collecting component 4 is provided below the cutting equipment component 1. The cutting equipment component 1 includes an equipment frame 100. A vertical electric guide rail 101 is fixedly connected to the front inner wall of the equipment frame 100. A sliding matching bracket 102 is installed at the output end of the vertical electric guide rail 101. An outer frame 103 is fixedly connected to the end of the sliding matching bracket 102 away from the vertical electric guide rail 101. A motor 104 is installed on the right side of the outer frame 103. A cutting circular blade 105 is installed at the output end of the motor 104. A material placement anti-slip platform 106 is fixedly connected to the lower inner wall of the equipment frame 100. Below the cutting circular blade 105, the linkage adaptive protection component 2 includes an L-shaped side linkage bracket 200 fixedly connected to both sides of the sliding matching bracket 102. A hollow linkage side protection frame 201 is fixedly connected to the lower end of the L-shaped side linkage bracket 200. The two hollow linkage side protection frames 201 are located on the left and right sides of the equipment frame 100, respectively. Multiple springs 203 are fixedly connected to the upper inner wall of the hollow linkage side protection frame 201. The multiple springs 203 are horizontally equidistant. A vertical adapter shielding side strip 202 is fixedly connected to the lower end of the springs 203. The fine adapter component 3 includes a hollow bottom groove 300 opened below the vertical adapter shielding side strip 202. A damping connecting shaft 301 is installed between the left and right inner walls of the hollow bottom groove 300. A vertical connecting plate 302 is installed outside the damping connecting shaft 301. A protruding follower extrusion plate 303 is fixedly connected to the lower end of the vertical connecting plate 302.

[0008] In the aforementioned cutting device for producing sofa iron frames with protective structures, this solution, through the synergistic effect of the linkage adaptive protection component and the fine fitting component, can provide all-round protection for the cutting area, meeting the actual needs of sofa iron frame production.

[0009] As a further improvement of this application, the vertically adaptable shielding side strip 202 and the hollow linkage side protective frame 201 are slidably connected, and the lower end of the protruding follow-up extrusion plate 303 is fixedly connected to a flexible bottom plate 304.

[0010] As a further improvement of this application, the lower end of the flexible bottom plate 304 is fixedly connected with a plurality of anti-slip contact strips 305, and the dust collection assembly 4 includes a bottom dust storage bin 400.

[0011] As a further improvement of this application, the bottom dust storage bin 400 is fixedly connected to the bottom of the equipment frame 100, and the front end of the bottom dust storage bin 400 is fixedly connected to a connecting pipe 401.

[0012] As another improvement of this application, a suction port 402 is fixedly connected to the upper end of the connecting pipe 401, and the suction port 402 extends into the vertical electrical guide rail 101.

[0013] As a further improvement to this application, the bottom dust storage bin 400 has a built-in pump, and the pump output end is connected to the connecting pipe 401.

[0014] As a further improvement to this application, a strip-shaped iron frame to be processed is placed on the material placement anti-slip platform 106, and multiple vertically adaptable shielding side strips 202 are respectively attached to the strip-shaped iron frame to be processed.

[0015] In summary, this solution, through the synergistic effect of the linkage adaptive protection components and the fine-fitting components, provides all-around protection for the cutting area. The vertically adapting shielding side strips, under the action of springs, tightly adhere to the iron frame to be processed. Combined with the flexible bottom plate and anti-slip contact strips, this effectively blocks flying debris generated during cutting, improving operational safety and preventing accidental injury. The L-shaped side linkage bracket moves synchronously with the sliding matching bracket, ensuring that the protection range always covers the cutting point, eliminating blind spots and enhancing the continuity and reliability of protection. The material placement anti-slip platform stably holds the iron frame to be processed, preventing... The device prevents workpiece slippage during cutting, ensuring cutting accuracy and improving product quality stability. The dust extraction component promptly removes dust and debris generated during cutting through the suction port and connecting pipe, collecting them in the bottom dust storage bin to reduce pollution to the working environment and protect the health of operators. The damping connecting shaft allows the vertical connecting plate to be flexibly adjusted to adapt to the processing needs of different specifications of iron frames, enhancing the versatility and adaptability of the device. The overall structure is compact and reasonable, with smooth linkage between components. While improving cutting efficiency, it also takes into account safety protection and environmental protection requirements, meeting the actual needs of sofa iron frame production.

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-7 A cutting device for producing sofa iron frames with a protective structure is shown, including a cutting equipment component 1, an adaptive protection component 2 at the upper end of the cutting equipment component 1, a fine fitting component 3 in the adaptive protection component 2, and a dust suction component 4 at the lower end of the cutting equipment component 1.

[0028] The cutting equipment assembly 1 includes an equipment frame 100. A vertical electric guide rail 101 is fixedly connected to the front inner wall of the equipment frame 100. A sliding matching bracket 102 is installed at the output end of the vertical electric guide rail 101. An outer frame 103 is fixedly connected to the end of the sliding matching bracket 102 away from the vertical electric guide rail 101. A motor 104 is installed on the right side of the outer frame 103. A cutting circular blade 105 is installed at the output end of the motor 104. A material placement anti-slip platform 106 is fixedly connected to the lower inner wall of the equipment frame 100. The material placement anti-slip platform 106 is located below the cutting circular blade 105.

[0029] The linkage adaptive protection component 2 includes an L-shaped side linkage bracket 200 fixedly connected to both sides of the sliding matching bracket 102. A hollow linkage side protection frame 201 is fixedly connected to the lower end of the L-shaped side linkage bracket 200. The two hollow linkage side protection frames 201 are located on the left and right sides of the equipment frame 100, respectively. Multiple springs 203 are fixedly connected to the upper inner wall of the hollow linkage side protection frame 201. The multiple springs 203 are horizontally equidistant from each other. A vertical adaptive shielding side strip 202 is fixedly connected to the lower end of the springs 203.

[0030] The fine-fitting component 3 includes a hollow bottom groove 300 below the vertical adapter shielding side strip 202. A damping connecting shaft 301 is installed between the left and right inner walls of the hollow bottom groove 300. A vertical connecting plate 302 is installed outside the damping connecting shaft 301. A protruding follower extrusion plate 303 is fixedly connected to the lower end of the vertical connecting plate 302. The vertical adapter shielding side strip 202 and the hollow linkage side protective frame 201 are slidably connected. A flexible bottom plate 304 is fixedly connected to the lower end of the protruding follower extrusion plate 303. Multiple anti-slip contact strips 305 are fixedly connected to the lower end of the flexible bottom plate 304. A strip-shaped iron frame to be processed is placed on the material placement anti-slip platform 106. The multiple vertical adapter shielding side strips 202 are respectively attached to each other with the strip-shaped iron frame to be processed.

[0031] Figures 1-7 Before starting work, the strip-shaped iron frame to be processed is placed on the material placement anti-slip platform 106 of the cutting equipment assembly 1. The anti-slip properties of the platform ensure the stable positioning of the iron frame. After the device is started, the vertical electric guide rail 101 of the cutting equipment assembly 1 drives the sliding matching bracket 102 to move vertically, thereby driving the external frame 103 fixed on the sliding matching bracket 102 to move synchronously. The motor 104 on the right side of the external frame 103 is started, driving the cutting circular blade 105 to rotate at high speed and gradually approach the iron frame on the material placement anti-slip platform 106, ready to carry out the cutting operation.

[0032] During the movement of the cutting circular blade 105, the linkage adaptive protection component 2 responds synchronously. The L-shaped side linkage brackets 200 on both sides of the sliding matching bracket 102 move together with the bracket, causing the hollow linkage side protection frame 201 at the lower end to move synchronously on both sides of the equipment frame 100. Multiple springs 203 inside the hollow linkage side protection frame 201 push the vertical adapter shielding side strip 202 to slide along the inner wall of the protection frame due to elastic potential energy, so that the vertical adapter shielding side strip 202 fits tightly against the side of the strip-shaped iron frame to be processed, forming preliminary lateral protection and blocking the lateral debris from flying during cutting.

[0033] Meanwhile, the fine-fitting component 3 further enhances the protective sealing. In the hollow bottom groove 300 below the vertical adapter shielding side strip 202, the damping connecting shaft 301 allows the vertical connecting plate 302 to rotate flexibly according to the surface shape of the iron frame, driving the lower protruding follower extrusion plate 303 to fit the bottom contour of the iron frame. The flexible bottom plate 304 at the lower end of the protruding follower extrusion plate 303 can deform slightly with the surface of the iron frame due to its flexibility. The multiple anti-slip contact strips 305 at its bottom are in close contact with the surface of the iron frame, which not only avoids the protective components from scratching the iron frame, but also fills the gaps through the multi-layer bonding structure to prevent small debris from escaping from the bottom. After the cutting is completed, the vertical electric guide rail 101 drives the sliding matching bracket 102 to drive the cutting round blade 105 to rise and reset. The spring 203 of the linkage adaptive protective component 2 rebounds, causing the vertical adapter shielding side strip 202 to detach from the iron frame and reset. The dust collection component 4 delays closing to ensure that the residual debris is completely sucked up, and finally a safe and clean cutting cycle is completed.

[0034] Second implementation method:

[0035] Figure 2 This invention illustrates a cutting device for producing sofa frame ironwork with a protective structure. The dust collection component 4 includes a bottom dust collection bin 400, which is fixedly connected to the bottom of the equipment frame 100. A connecting pipe 401 is fixedly connected to the front end of the bottom dust collection bin 400, and a suction port 402 is fixedly connected to the upper end of the connecting pipe 401. The suction port 402 extends into a vertical electrical guide rail 101. A pump is built into the bottom dust collection bin 400, and the pump output is connected to the connecting pipe 401. When the cutting circular blade 105 contacts the ironwork frame... During cutting, the dust collection component 4 starts simultaneously, and the pump built into the bottom dust collection bin 400 generates negative pressure. The suction force is transmitted through the connecting pipe 401 to the dust collection opening 402 extending into the vertical electric guide rail 101. The dust collection opening 402 is precisely aligned with the contact point between the cutting circular blade 105 and the iron frame, sucking in the metal chips and dust generated during cutting in real time. The dust is then collected in the bottom dust collection bin 400 through the connecting pipe 401, achieving centralized treatment of cutting pollution. This can be used as an optional accessory in cutting areas with limited space, eliminating the need for additional dust collection devices.

[0036] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
