Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, and in particular to a deformation-resistant metal cutting device and a metal cutting processing method. Background Technology

[0002] Metalworking, or simply metal processing, is an important activity widely present in industrial production. It mainly refers to the production process in which humans use various technical means to process materials composed primarily of metallic elements and possessing metallic properties. This process encompasses multiple stages from raw materials to finished products. Among these, cutting metal using cutting devices is an indispensable part of metalworking, and it is a specific operational method within metalworking.

[0003] However, in practical applications, existing metal processing and cutting devices have some problems that urgently need to be solved. Specifically, most common cutting devices currently use a cutting motor to drive a cutting wheel to rotate at high speed to cut metal blocks. However, before the cutting operation, the metal block must be accurately positioned. The problem is that the upper part of the positioned metal block is usually in an unconstrained state. When the cutting wheel cuts it, the lack of effective limiting measures on the outside of the metal block easily leads to deviations in the cutting position.

[0004] This deviation in the cutting position will further cause deformation of the metal block when precise cutting is required later. This deformation will not only affect the metal block's appearance but may also adversely impact its performance. Summary of the Invention

[0005] In order to at least solve one of the above-mentioned technical problems, the present invention aims to provide a deformation-resistant metal cutting device and a metal cutting processing method, which provides effective limiting and reduces the possibility of deviation and deformation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A deformation-resistant metal cutting device includes a worktable, a cutting frame fixedly mounted on top of the worktable, a cutting mechanism fixedly connected to the cutting frame via a lifting mechanism, a strip-shaped cutting groove on the worktable, clamping mechanisms on both sides of the cutting groove, the clamping mechanism including a clamping cylinder fixedly connected to the edge of the worktable, a clamping frame fixedly connected to the movable part of the clamping cylinder facing the cutting groove, a clamping plate fixedly mounted on the clamping frame facing the cutting groove, a corner cylinder fixedly connected to the back of the clamping plate, and a lower pressure plate fixedly connected to the movable part above the corner cylinder.

[0008] Preferably, the lifting mechanism is a lifting cylinder.

[0009] Preferably, the lifting mechanism further includes multiple sliding telescopic rods, the two ends of which are fixedly connected to the cutting frame and the cutting mechanism, respectively.

[0010] Preferably, the cutting mechanism includes a connecting frame connected to the lifting mechanism, a cutting motor is fixedly connected to the bottom of the connecting frame, and a cutting blade wheel is fixedly connected to the output shaft of the cutting motor.

[0011] Preferably, the connecting frame is configured as an inverted tripod shape, and a blower facing the cutting wheel is provided inside the connecting frame.

[0012] Preferably, the worktable surface, the working surface of the lower pressure plate, and the working surface of the clamping plate are all coated with a wear-resistant and anti-slip coating.

[0013] Preferably, a collection box is provided at the bottom of the workbench, and the cutting groove is connected to the collection box.

[0014] Preferably, a cleaning door is provided on one side of the collection box, and a transparent observation window is provided on the cleaning door.

[0015] Preferably, a vacuum pump is connected to one side of the collection box, and a filter screen is installed at the inlet of the vacuum pump.

[0016] A deformation-resistant metal cutting process includes the following steps:

[0017] Place the metal to be cut on both sides of the cutting groove of the worktable, activate the clamping cylinder to move the clamping plate toward the cutting groove, and clamp the metal to be cut between the clamping plate and the edge of the cutting groove.

[0018] The rotary cylinder is activated, causing the lower pressure plate to rotate downwards and press against the upper surface of the metal to be cut, further fixing the metal to be cut.

[0019] Activate the lifting cylinder in the lifting mechanism to lower the cutting mechanism to a suitable cutting height, and at the same time slide the telescopic rod to extend and retract as the cutting mechanism descends;

[0020] Start the cutting motor to drive the cutting wheel to rotate and perform the cutting operation on the metal to be cut.

[0021] The present invention has the following beneficial effects:

[0022] I. Effective Limitation Reduces Deviation and Deformation: Existing metal processing and cutting devices leave the upper part of the metal block unconstrained after positioning. During cutting, the lack of effective limiting measures on the outside easily leads to cutting position deviation, causing deformation of the metal block and affecting its appearance and performance. The anti-deformation metal cutting device of this invention features clamping mechanisms on both sides of the cutting groove on the worktable. Clamping cylinders push the clamping frame to clamp the metal to be cut between the clamping plate and the edge of the cutting groove. Simultaneously, corner cylinders rotate the lower pressure plate downwards to press against the upper surface of the metal to be cut. This effectively limits the metal to be cut from both horizontal and vertical directions, reducing the possibility of cutting position deviation and metal block deformation.

[0023] II. Stable Lifting and Lowering of the Cutting Mechanism: The lifting mechanism of this invention is a lifting cylinder, and also includes multiple sliding telescopic rods. Both ends of the sliding telescopic rods are fixedly connected to the cutting frame and the cutting mechanism, respectively. When the lifting cylinder is activated to lower the cutting mechanism to a suitable cutting height, the sliding telescopic rods extend and retract with the descent of the cutting mechanism, providing stable guidance and support for the lifting and lowering of the cutting mechanism. This ensures the stability of the cutting mechanism during the lifting and lowering process, and helps improve the accuracy and quality of the cutting.

[0024] 3. Facilitates the cleaning of cutting debris: A collection box is installed at the bottom of the workbench, connected to the cutting groove, allowing debris generated during cutting to fall directly into the collection box. A cleaning door is located on one side of the collection box for convenient, periodic cleaning of the debris; a transparent observation window on the cleaning door allows for constant monitoring of debris accumulation for timely removal. Furthermore, an exhaust fan is connected to one side of the collection box, with a filter installed at the fan inlet. The exhaust fan draws fine debris and dust generated during cutting into the collection box, while the filter prevents debris from entering the exhaust fan and damaging the equipment, further improving the working environment.

[0025] IV. Optimized Cutting Environment: The connecting frame is designed as an inverted triangular frame, which provides greater stability and better withstands the weight and vibration of the cutting motor and cutting wheel. A blower is installed inside the connecting frame, facing the cutting wheel. During cutting, the blower removes debris and heat, reducing debris interference with the cutting wheel, lowering the risk of overheating damage, extending the cutting wheel's lifespan, and improving cutting efficiency and quality.

[0026] 5. Enhanced component durability: The worktable surface, the working surface of the lower pressure plate, and the working surface of the clamping plate are all coated with a wear-resistant and anti-slip coating. During the cutting process, these working surfaces will frequently come into contact with and rub against the metal to be cut. The wear-resistant and anti-slip coating can effectively reduce the wear of the components and improve their durability. At the same time, the anti-slip performance can better fix the metal to be cut and ensure the stability of the cutting process. Attached Figure Description

[0034] 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.

[0035] First embodiment

[0036] like Figures 1 to 3As shown, a deformation-resistant metal cutting device includes a worktable 1, a cutting frame 2 fixedly mounted on the worktable 1, and a cutting mechanism fixedly connected to the cutting frame 2 via a lifting mechanism. A strip-shaped cutting groove 101 is provided on the worktable 1, and clamping mechanisms are provided on both sides of the cutting groove 101. The clamping mechanism includes a clamping cylinder 301 fixedly connected to the edge of the worktable 1, a clamping frame 302 fixedly connected to the movable part of the clamping cylinder 301 facing the cutting groove 101, a clamping plate 303 fixedly mounted on the clamping frame 302 facing the cutting groove 101, a corner cylinder 304 fixedly connected to the back of the clamping plate 303, and a lower pressure plate 305 fixedly connected to the movable part above the corner cylinder 304.

[0037] like Figures 1 to 3 As shown, the workbench 1 serves as the basic support structure for the entire device, providing a platform for the installation and operation of other components. The cutting frame 2 is fixedly mounted above the workbench 1, providing an installation position for the cutting mechanism. It is connected to the cutting mechanism via a lifting mechanism, allowing the cutting mechanism to move vertically to adjust the cutting height and adapt to the cutting requirements of metals of different thicknesses. The strip-shaped cutting groove 101 on the workbench 1 provides a cutting channel for the cutting wheel 502, enabling accurate cutting operations. Furthermore, the metal to be cut is placed on both sides of the cutting groove 101, and the edges of the cutting groove 101 are used for preliminary horizontal positioning of the metal, determining the approximate cutting position in the horizontal direction. The clamping cylinder 301 is fixedly connected to the edge of the workbench 1, with its movable part facing the cutting groove 101. When the clamping cylinder 301 is activated, the movable part pushes the clamping frame 302 towards the cutting groove 101, and the clamping plate 303 on the clamping frame 302 moves accordingly, clamping the metal to be cut between the clamping plate 303 and the edge of the cutting groove 101. In this way, the metal to be cut is fixed horizontally, preventing displacement due to cutting force during the cutting process and ensuring accurate cutting position. An angle cylinder 304 is fixedly connected to the back of the clamping plate 303 of the clamping frame 302, and a lower pressure plate 305 is fixedly connected to its movable part. When the angle cylinder 304 is activated, the movable part drives the lower pressure plate 305 to rotate downwards until it presses firmly against the upper surface of the metal to be cut. This vertically presses and fixes the metal, further enhancing its stability during cutting and preventing vertical jumping or deformation caused by vibration or uneven force during cutting, thus effectively reducing deformation during metal cutting.

[0038] like Figures 1 to 3As shown, the lifting mechanism is a lifting cylinder 401. The lifting mechanism also includes multiple sliding telescopic rods 402, with both ends of the sliding telescopic rods 402 fixedly connected to the cutting frame 2 and the cutting mechanism, respectively. The lifting cylinder 401 serves as a power source, achieving the vertical lifting and lowering of the cutting mechanism through the extension and retraction of its piston. When the piston of the lifting cylinder 401 extends, it pushes the cutting mechanism downwards, bringing the cutting blade wheel 502 closer to the metal to be cut; when the piston retracts, it drives the cutting mechanism upwards, moving the cutting blade wheel 502 away from the metal that has been cut or adjusting it to a suitable initial height. Both ends of the multiple sliding telescopic rods 402 are fixedly connected to the cutting frame 2 and the cutting mechanism, respectively. During the lifting process of the lifting cylinder 401 driving the cutting mechanism to rise and fall, the sliding telescopic rods 402 play a guiding and stabilizing role. They ensure that the cutting mechanism moves smoothly in the vertical direction, preventing swaying or deviation during the lifting and lowering process, thereby improving cutting accuracy. For example, when the cutting mechanism descends to cut, the sliding telescopic rods 402 retract as the cutting mechanism descends, always maintaining connection with the cutting frame 2 and the cutting mechanism, ensuring the accurate movement trajectory of the cutting mechanism.

[0039] like Figures 1 to 3 As shown, the cutting mechanism includes a connecting frame 403 connected to a lifting mechanism. A cutting motor 501 is fixedly connected to the bottom of the connecting frame 403, and a cutting wheel 502 is fixedly connected to the output shaft of the cutting motor 501. The connecting frame 403 is designed as an inverted triangle, and a blower 503 facing the cutting wheel 502 is installed inside the connecting frame 403. The inverted triangle design of the connecting frame 403 provides high stability and strength, and can withstand the vibration and impact forces generated by the cutting motor 501 and the cutting wheel 502 during the cutting process. At the same time, the inverted triangle-shaped connecting frame 403 provides reasonable installation space for the cutting motor 501 and the blower 503, making the entire cutting mechanism compact. The cutting motor 501 is fixedly connected to the bottom of the connecting frame 403, and its output shaft is fixedly connected to the cutting wheel 502. When the cutting motor 501 starts, the output shaft drives the cutting wheel 502 to rotate at high speed. The high-speed rotating cutting wheel 502 contacts the metal to be cut, and cuts the metal through friction and cutting force, thus realizing the cutting operation. The blower 503 is located inside the connecting bracket 403 and faces the cutting wheel 502. During the cutting process, metal cutting generates a large amount of debris and heat. The airflow from the blower 503 can blow these debris away from the cutting wheel 502, preventing debris from accumulating on the cutting wheel 502 and affecting the cutting effect. At the same time, it can also play a certain role in heat dissipation, reducing the temperature of the cutting wheel 502 and extending its service life.

[0040] like Figures 1 to 3As shown, the worktable surface of the workbench 1, the working surface of the lower pressure plate 305, and the working surface of the clamping plate 303 are all coated with a wear-resistant and anti-slip coating. This coating increases the friction between these components and the metal to be cut. When clamping and pressing the metal, the wear-resistant and anti-slip coating prevents the metal from sliding or shifting due to cutting forces, ensuring the stability of the metal during cutting and thus improving cutting accuracy and quality. Simultaneously, the wear-resistant and anti-slip coating also reduces surface wear, extending the service life of the workbench 1, the lower pressure plate 305, and the clamping plate 303.

[0041] A deformation-resistant metal cutting process includes the following steps:

[0042] The metal to be cut is placed on both sides of the cutting groove 101 on the worktable 1. The cutting groove 101 provides an initial horizontal position reference for the metal. After the clamping cylinder 301 is activated, the moving part of the clamping cylinder 301 pushes the clamping plate 303 towards the cutting groove 101. The clamping plate 303 and the edge of the cutting groove 101 work together to clamp the metal to be cut horizontally. This clamping method can prevent the metal from shifting horizontally due to the horizontal component of the cutting force during subsequent cutting, ensuring the accuracy of the cutting position.

[0043] The corner cylinder 304 is activated, and its movable part drives the lower pressure plate 305 to rotate downwards until it presses firmly against the upper surface of the metal to be cut. By applying pressure to the metal to be cut in the vertical direction, the metal is further fixed, preventing it from jumping or deforming in the vertical direction due to vibration or uneven force during cutting, thereby effectively reducing deformation problems during metal cutting.

[0044] The lifting cylinder 401 in the lifting mechanism is activated, and the piston of the lifting cylinder 401 extends, pushing the cutting mechanism downward. At the same time, the sliding telescopic rod 402 extends and retracts with the descent of the cutting mechanism. The sliding telescopic rod 402 plays a guiding role, ensuring that the cutting mechanism descends smoothly in the vertical direction, so that the cutting blade 502 can accurately reach the appropriate cutting height, preparing for subsequent cutting operations.

[0045] Once the cutting mechanism descends to the appropriate cutting height, the cutting motor 501 is activated. The output shaft of the cutting motor 501 drives the cutting wheel 502 to rotate at high speed. The high-speed rotating cutting wheel 502 contacts the metal to be cut, and the metal is cut off through friction and cutting force, thus completing the cutting operation.

[0046] Second embodiment

[0047] like Figures 4 to 5As shown, a collection box 601 is installed at the bottom of the workbench 1, and the cutting groove 101 is connected to the collection box 601. During the metal cutting process, the generated debris falls into the collection box 601 through the cutting groove 101, achieving centralized collection of cutting debris and preventing debris from scattering on the workbench 1 or the surrounding environment, keeping the work area clean and reducing subsequent cleaning workload. A cleaning door 602 on one side of the collection box 601 has a transparent observation window 603, allowing the operator to observe the accumulation of debris in the collection box 601 at any time. When the collection box 601 is observed to be nearly full of debris, the cleaning door 602 can be opened in time to clean the debris and prevent debris from overflowing the collection box 601. A vacuum pump 604 is connected to one side of the collection box 601, which creates a negative pressure environment inside the collection box 601 when it is working. On the one hand, negative pressure helps to draw fine dust and debris generated during the cutting process into the collection box 601, further improving the collection effect; on the other hand, the filter screen 605 installed at the inlet of the vacuum pump 604 can filter out debris and dust in the sucked-in gas, preventing these impurities from entering the vacuum pump 604 and damaging it, while ensuring that the discharged gas is relatively clean and reducing pollution to the surrounding environment.

[0048] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
