Description

Technical Field

[0001] This invention belongs to the field of cutting machine technology, and in particular relates to a novel and convenient steel mesh cutting device. Background Technology

[0002] Steel mesh and thin sheet metal are widely used in industrial production, including construction, machinery manufacturing, and heat treatment workshops. Currently, steel mesh cutting equipment on the market mainly includes traditional shearing machines and fixed cutting machines. These devices are typically hydraulically or electrically driven, but their functions are limited, only capable of unidirectional cutting (e.g., transverse or longitudinal). For example, when cutting steel mesh, a common shearing machine first needs to perform a transverse cut to obtain the required length, then manually adjust the material direction or change equipment to perform a longitudinal cut to achieve the desired width. This process is not only time-consuming but also cumbersome, severely impacting production efficiency. Furthermore, existing equipment often uses fixed-mount cutting blades, making replacement difficult and unable to quickly adapt to the processing needs of different materials or thicknesses. While some equipment has a feeding function, the lack of linkage between the feeding mechanism and the cutting mechanism results in low positioning accuracy, easily leading to material waste or cutting deviations. Additionally, traditional cutting machines have complex structures and high maintenance costs, especially for small and medium-sized workshops, where the burden of equipment purchase and maintenance is significant.

[0003] Therefore, there is an urgent need for an integrated, convenient, and multifunctional cutting device for steel mesh cutting to improve processing efficiency and quality. Summary of the Invention

[0004] This invention addresses the problems of existing technologies, such as single cutting direction, inconvenient tool replacement, complex structure, safety concerns, and poor adaptability. It proposes a novel, convenient steel mesh cutting device, comprising: a main frame, a transmission mechanism, a feeding mechanism, and a cutting mechanism. The device is characterized by: a support frame in the lower half of the main frame; a horizontal platform on the upper part of the main frame; the support frame including: a first rotatable roller, a second rotatable roller, and a third rotatable roller, arranged in an inverted triangle; wherein the first and second rotatable rollers are parallel and positioned upwards, with a roller gear at one end of the first rotatable roller; and the third rotatable roller is positioned downwards; the support frame is used to support rolled materials. The transmission mechanism includes a crank handle and a transmission component, with the crank handle hinged to the transmission component; the transmission component is hinged to a first rotatable roller; by rotating the crank handle, the first rotatable roller is driven to rotate via the transmission component. The feeding mechanism includes a feeding roller and a clamping mechanism; the clamping mechanism is respectively disposed at both ends of the feeding roller; the clamping mechanism includes: a spring, a pressure plate, and a bolt; the bolt is vertically fixed on the main frame; the pressure plate is provided with a threaded hole for threaded connection with the bolt; one end of the spring is fixed on the lower surface of the pressure plate; the other end of the spring clamps the feeding roller; the distance between the feeding roller and the table surface can be adjusted by turning the bolt; The cutting mechanism includes a transverse cutting component and a longitudinal cutting component. The transverse cutting component includes: a transverse cutting drill, a slide plate, a carriage, a gear set, and a transverse cutting blade. The carriage is horizontally mounted on the main frame. The slide plate is slidably mounted on the carriage. The transverse cutting drill is mounted on the slide plate. A gear set is mounted at the front end of the transverse cutting drill. The gear set is connected to the transverse cutting blade. The transverse cutting drill drives the gear set to rotate the transverse cutting blade. The transverse cutting blade achieves transverse cutting by moving the slide plate. The longitudinal cutting component includes a side fixing plate, a tie rod, and a side frame. The tie rod is telescopically mounted on one side of the main frame. The extension and retraction direction of the tie rod is perpendicular to the movement direction of the slide plate. The side fixing plate is equipped with a side drill and a side blade. The longitudinal cutting of the side blade is achieved by pulling the tie rod.

[0005] According to the above-described novel convenient steel mesh cutting device, the first rotatable roller, the second rotatable roller, and the third rotatable roller of the bracket are all welded with bracket bearings at both ends.

[0006] According to the above-described novel convenient steel mesh cutting device, the feeding roller is provided with feeding roller bearings on both sides; there are two clamping mechanisms, which are respectively provided on both sides of the main frame. One end of the spring of the clamping mechanism is provided on the feeding roller bearing of the feeding roller. Tightening the bolt can increase the pressure of the pressure plate on the feeding roller bearing, thereby adjusting the clamping force between the feeding roller and the table.

[0007] According to the above-described novel convenient steel mesh cutting device, both ends of the transmission component are equipped with transmission gears. The two transmission gears and the chains on them are respectively connected to the shaft gear on the crank handle and the roller gear on the first rotatable roller, so that the crank handle drives the first rotatable roller to rotate and feed the coiled material.

[0008] According to the above-described novel convenient steel mesh cutting device, the slide plate and the carriage of the transverse cutting component are connected by a guide rail; the gear set adopts a standard reduction structure.

[0009] According to the above-described novel convenient steel mesh cutting device, the side fixing plate of the longitudinal cutting component is hinged to the side frame, one end of the pull rod is fixed to the side fixing plate, and the other end extends to the operating end of the pull rod; when the pull rod is pulled, the side fixing plate drives the side blade set on the side electric drill to move longitudinally to complete the longitudinal cutting.

[0010] According to the above-described novel convenient steel mesh cutting device, the electric drill and the side-mounted electric drill are both detachable electric drills, which are respectively snapped and fixed on the sliding plate and the side fixing plate.

[0011] According to the above-described novel convenient steel mesh cutting device, the main frame adopts a welded steel structure, and the surface of the table set on its upper part is ground.

[0012] According to the above-described novel convenient steel mesh cutting device, the surface of the feeding roller is covered with a rubber layer to increase the friction with the material; the rubber layer is removable and replaceable.

[0013] According to the above-described novel convenient steel mesh cutting device, the transmission component also includes a tension wheel, which is fixedly mounted on the main frame by bolts and is used to adjust the tension of the chain.

[0014] The beneficial effects of this invention are as follows: 1. Significantly Improves Cutting Accuracy and Product Quality. In existing technologies, manual cutting of steel mesh relies heavily on operator experience and feel, easily leading to problems such as skewed cuts, numerous burrs, and dimensional errors. This invention fundamentally improves cutting quality by integrating a high-precision clamping mechanism. First, the ground table provides a precise reference plane for cutting. Second, the feeding mechanism, through elastic clamping—springs and bolts—ensures the steel mesh does not shift during cutting. The transverse cutting component uses a guide rail slide structure, ensuring the transverse cutting blade's movement trajectory is linear, avoiding the shaking and instability of manual pushing. Longitudinal cutting is guided by a retractable pull rod, ensuring the straightness of the longitudinal cut. This combination of mechanical guidance and stable clamping results in a significantly higher repeatability of each cut compared to manual operation, effectively reducing scrap rates and improving product consistency and quality.

[0015] 2. Significantly Improved Production Efficiency and Yield. Compared to traditional manual segmented measurement, marking, and cutting, the integrated design of this invention concentrates material feeding, conveying, and cutting functions into one machine, achieving centralized and streamlined operations, resulting in a significant increase in yield. The transmission mechanism, through a crank handle and chain drive, allows for quick and labor-saving material feeding and fine-tuning of material position, replacing heavy manual dragging. The conveying mechanism ensures smooth and accurate material feeding, reducing the time spent on repeated adjustments. The cutting mechanism separates transverse and longitudinal cutting functions, allowing operators to complete both types of cutting without changing tools, reducing the time spent on process transitions. In particular, the transverse cutting speed, with its sliding plate moving much faster than manual sawing, is significantly faster. For batch tasks requiring multi-segment cutting, this efficiency advantage is even more pronounced, greatly increasing the number of qualified pieces completed per unit time.

[0016] 3. Simple and flexible operation, reducing labor intensity and skill dependence. This invention simplifies the cutting operation and reduces reliance on operator skills. Both the transmission and feeding mechanisms are manually adjustable, requiring no complex electrical control knowledge. The cutting power comes from a common detachable electric drill, which has low procurement and maintenance costs and high versatility. The clamping force of the clamping mechanism can be steplessly adjusted by turning the bolts, quickly adapting to materials of different thicknesses and materials. The rubber layer of the feeding roller is replaceable, extending the life of the components. The inverted triangular layout of the support makes loading and unloading more stable and labor-saving. The entire equipment structure is clear at a glance, and ordinary workers can operate it after brief training, greatly reducing labor intensity and training costs.

[0017] 4. Achieving Energy Saving and Low-Cost Operation. Compared with large-scale automated CNC cutting equipment, this invention achieves mechanized cutting while offering significant advantages in energy saving and low cost. Large CNC equipment typically relies on high-power motors and complex control systems, resulting in high energy consumption and large investment. This invention has no other power-consuming components besides the cutting drill. The drill used is a general-purpose tool with low cost. The entire machine has a compact structure, uses less material, and has a manufacturing cost far lower than large equipment. For small and medium-sized enterprises or construction sites, this invention maximizes economic benefits by minimizing equipment purchase costs and daily operating energy consumption while ensuring basic cutting functions and accuracy.

[0018] 5. Improved Work Safety and Environment. Manual cutting of steel mesh, especially when using tools like angle grinders, is extremely noisy and generates sparks, posing serious safety hazards and environmental pollution. This invention effectively addresses this issue through its structural design. The high-speed rotating cutting blade is confined to a specific trajectory and positioned above the worktable, reducing the risk of accidental contact with the operator. Cutting is performed on a stable worktable, preventing injuries caused by material slippage. Compared to fully open manual cutting, the structure of this invention restricts the range of sparks and metal shavings to a certain extent, making it easy to equip the worktable with collection devices, thus improving the working environment. Although noise is still generated, the use of a universal electric drill and a smoother cutting process generally results in less noise and vibration than high-powered tools like handheld angle grinders, reducing the negative impact on the operator and the surrounding environment.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figures 1 to 4 As shown: A convenient steel mesh cutting machine according to this embodiment includes a main frame 14, a transmission mechanism, a feeding mechanism and a cutting mechanism.

[0026] The main frame 14 serves as the basic support structure and is preferably made of square tubing or channel steel welded together, providing good rigidity and stability to ensure that the entire machine does not vibrate violently during the cutting process. The lower half of the main frame 14 is equipped with a support bracket 1 for supporting the rolled steel mesh material, and the upper part is horizontally equipped with a ground table 13, which provides a flat and smooth reference plane for the conveying and cutting of the steel mesh.

[0027] The support bracket 1 is fixedly installed on the lower half of the main frame 14. Its core function is to support the rolled steel mesh material and ensure orderly feeding. The support bracket 1 includes a first rotatable roller 101, a second rotatable roller 102, and a third rotatable roller 103. These three are arranged in an inverted triangle: the first and second rotatable rollers 101 and 102 are parallel and positioned higher, forming the main support for the material roll; the third rotatable roller 103 is positioned lower, serving to guide and stabilize the material roll. To reduce rotational resistance, support bearings are welded to both ends of the first, second, and third rotatable rollers 101, 102, and 103. A roller gear is also provided at one end of the first rotatable roller 101 for connection to the transmission mechanism.

[0028] The transmission mechanism provides power for unloading the material. This mechanism includes a crank handle 3 and a transmission component 2. The crank handle 3 is hinged to one end of the transmission component 2. The transmission component 2 is a chain drive system with transmission gears at both ends, connected by a chain to the shaft gear on the crank handle 3 and the roller gear on the first rotatable roller 101. When the operator turns the crank handle 3 clockwise or counterclockwise, power is transmitted through the chain, driving the first rotatable roller 101 to rotate, thus slowly releasing the rolled steel mesh. To further optimize transmission performance, the transmission component 2 also includes a tensioning wheel, which is bolted to the main frame 14. Adjusting its position changes the chain tension, ensuring smooth and reliable transmission.

[0029] The feeding mechanism is responsible for pressing and conveying the steel mesh material released from the support 1 forward. It includes a feeding roller 6 and two symmetrically arranged pressing mechanisms 5. Feeding roller bearings 4 are installed at both ends of the feeding roller 6, allowing it to rotate flexibly. To increase the friction with the surface of the steel mesh, the surface of the feeding roller 6 is covered with a removable and replaceable rubber layer.

[0030] The clamping mechanisms 5 are respectively located above both ends of the feeding rollers 6. Each clamping mechanism 5 includes a spring 51, a pressure plate 52, and a bolt 53. The bolt 53 is vertically fixed to the crossbeam of the main frame 14. The pressure plate 52 has a threaded hole in its center, forming a helical pair with the bolt 53. The upper end of the spring 51 is fixed to the lower surface of the pressure plate 52, while the lower end presses against the feeding roller bearing 4 of the feeding roller 6. When the operator tightens the bolt 53, the pressure plate 52 presses down, and the pressure is transmitted to the feeding roller bearing 4 through the spring 51, thereby increasing the clamping force between the feeding roller 6 and the lower platform 13, ensuring that the feeding process does not slip. The use of the spring 51 provides elastic pressure, which can adapt to steel mesh of different thicknesses.

[0031] The cutting mechanism is divided into a transverse cutting component and a longitudinal cutting component.

[0032] The transverse cutting component is used to cut the width of the steel mesh. It includes a transverse cutting drill 7, a slide plate 8, a carriage 9, a gear set 15, and a transverse cutting blade 16. The carriage 9 is horizontally fixed on the main frame 14, with its direction perpendicular to the feeding direction. The slide plate 8 is slidably mounted on the carriage 9 via guide rails. The transverse cutting drill 7 is detachably fixed to the slide plate 8 by clips. The output shaft of the transverse cutting drill 7 is connected to the front end of the gear set 15, which adopts a standard reduction structure and can adjust the output speed and torque as needed. The output shaft of the gear set 15 is connected to the transverse cutting blade 16. After the transverse cutting drill 7 is started, power is transmitted through the gear set 15, driving the transverse cutting blade 16 to rotate at high speed. The operator pushes the slide plate 8 along the carriage 9, and the rotating blade completes the transverse cutting of the steel mesh.

[0033] The longitudinal cutting component is used to cut the steel mesh along its length. It includes a side fixing plate 12, a pull rod 11, and a side frame 10. The side frame 10 is fixed to one side of the main frame 14. The pull rod 11 is telescopically mounted on the main frame 14, and its extension direction is perpendicular to the movement direction of the slide plate 8, i.e., laterally. The side fixing plate 12 is connected to the side frame 10 via a hinge, and a side drill and a side blade are detachably mounted on it via clips. One end of the pull rod 11 is fixed to the side fixing plate 12, and the other end extends to a convenient operating position. When longitudinal cutting is required, the operator pulls the pull rod 11 outward, and the side fixing plate 12 then drives the side drill and the side blade to move along the length of the steel mesh, completing the longitudinal cut.

[0034] During operation, the rolled steel mesh is first placed on the support 1, and the protruding material head passes between the feeding roller 6 and the table 13, and is laid flat on the table 13. The feeding pressure is adjusted according to the steel mesh thickness via the clamping mechanism 5. The handle 3 is turned to release the material through the transmission mechanism, and the steel mesh is manually fed to the predetermined cutting position. For transverse cutting, the transverse cutting drill 7 is started, pushing the slide plate 8 to move laterally to complete the cut. For longitudinal cutting, the side-mounted drill is started, pulling the lever 11 to complete the cut. All drills are detachable for easy replacement and maintenance.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
