Description

Technical Field

[0001] This invention belongs to the field of machining and relates to a steel plate cutting device. Background Technology

[0002] Steel plate is an important metallic material widely used in construction, machinery, automobiles, shipbuilding, and many other fields. It is made by heating flat steel billets to a high temperature and then performing rolling, cooling, and leveling processes. The thickness, width, and length of steel plates can be customized according to actual needs. Steel plates have a wide range of applications in various industries, such as construction, machinery manufacturing, automotive, and shipbuilding.

[0003] According to the China Patent Network (Publication No.: CN221389106U), a steel plate cutting clamping device is disclosed. By setting up a disassembly and assembly mechanism, the user can easily install the clamping plate through the disassembly and assembly mechanism, and the user can also disassemble the clamping plate through the disassembly and assembly mechanism, so as to facilitate the user to replace the clamping plate. The clamping plate can be replaced with a clamping plate suitable for clamping workpieces of different shapes, which facilitates the limiting of workpieces and improves the stability of workpiece clamping.

[0004] While the aforementioned existing technologies can achieve the desired results using their structures, they still suffer from the following drawbacks: it is difficult to collect and filter harmful gases generated during cutting. Furthermore, because the steel plate contains sulfur, hydrogen sulfide may be generated during the cutting process. This toxic gas irritates the eyes, nose, and throat, and high concentrations of hydrogen sulfide can even be fatal. Therefore, this paper proposes a steel plate cutting device that can filter harmful gases. Summary of the Invention

A limit strip 36 is fixedly installed on the top of the clamping plate 35. By activating the cylinder 32, the sliding block 33 is moved, which in turn causes the two clamping plates 35 to retract. Under the action of the limit strip 36, the placed steel plate is clamped.

[0010] As a further preferred embodiment of the present invention, a plurality of metal cones 37 are fixedly installed on the top of the clamping plate 35, and the plurality of metal cones 37 are arranged in an array to support the steel plate.

[0011] As a further preferred embodiment of the present invention, the moving component 40 includes two translation slots 401 formed on the top of the housing 10, a moving slot 402 formed on the top of the housing 10, a base block 404, a motor 405, a threaded rod 403, and a moving block 406. The moving slot 402 is located between the two translation slots 401. The threaded rod 403 is rotatably connected to the left and right sides of the moving slot 402. The base block 404 is fixedly installed on one side of the housing 10. The motor 405 is fixedly installed on the base block 404. The motor 405 is connected to the threaded rod 403. By starting the motor 405, the threaded rod 403 is driven to rotate, which in turn causes the moving block 406 to move horizontally, thereby realizing the left and right movement of the laser head 13.

[0012] As a further preferred embodiment of the present invention, the moving component 40 includes a moving block 406 threadedly connected to the outer wall of the threaded rod 403, a support plate 407, two rectangular blocks 408, and an electric slide rail 409.

The two rectangular blocks 408 are slidably connected to the inside of two translation grooves 401 respectively. The electric slide rail 409 is fixedly installed on the bottom of the rectangular blocks 408. By activating the electric slide rail 409, the laser head 13 is driven to move back and forth, thereby further adjusting the laser head 13. By sliding the two rectangular blocks 408 inside the translation grooves 401, the laser head 13 is kept in balance when moving.

[0013] As a further preferred embodiment of the present invention, the lifting assembly 41 includes an electric telescopic rod 411 and a snap-fit ​​box 412 fixedly installed at the bottom of the electric slide rail 409. The snap-fit ​​box 412 is fixedly installed at the output end of the electric telescopic rod 411. A snap-fit ​​block 413 is snapped into the inside of the snap-fit ​​box 412. The laser head 13 is fixedly installed at the bottom of the snap-fit ​​block 413. By activating the electric telescopic rod 411, the laser head 13 is driven to extend and retract, so that the laser head 13 can cut the steel plate.

[0014] By activating the exhaust mechanism 21, multiple exhaust fans 213 draw outside air into the housing 10, allowing the gas generated during internal cutting to enter the filter mechanism 20. The gas passes through the filter screen 204, where harmful gases are blocked and purified. Activating the clamping mechanism 3 moves the clamping plate 35, clamping the steel plate placed on top of it. Activating the telescopic mechanism 4 moves the laser head 13 to cut different parts of the steel plate. The filter screen 204 again blocks and purifies the harmful gases. Manually pulling the handle 205 forward allows the filter frame 203 to slide within multiple pull slots 202 for replacing the filter screen 204. Activating the exhaust fans 213 draws outside air into the housing 10 through the air inlet slot 211, sending harmful gases into the filter box 12. The installed fans... The frame 212 is used to install multiple exhaust fans 213 to prevent vibration when the multiple exhaust fans 213 rotate. By starting the cylinder 32, the sliding block 33 is moved, which in turn causes the two clamping plates 35 to retract. Under the action of the limit bar 36, the placed steel plate is clamped. Multiple metal cones 37 are installed to support the steel plate and prevent damage to the equipment during cutting. By starting the motor 405, the threaded rod 403 is rotated, which in turn causes the moving block 406 to move horizontally, thereby enabling the laser head 13 to move left and right for accurate cutting of the steel plate. By starting the electric slide rail 409, the laser head 13 is moved back and forth to further adjust the laser head 13. By having two rectangular blocks 408 slide inside the translation groove 401, the laser head 13 is kept balanced during movement. By starting the electric telescopic rod 411, the laser head 13 is extended and retracted, allowing the laser head 13 to cut the steel plate.

[0015] The beneficial effects of this invention are: 1. When the steel plate cutting device is performing steel plate cutting operations, it activates the exhaust mechanism, which drives multiple exhaust fans to draw outside air into the housing. This allows the gas generated during the cutting process to enter the filtration mechanism. By passing through the filter screen, harmful gases inside are blocked and purified, effectively protecting the respiratory safety of the workers.

[0016] 2. This steel plate cutting device, by activating the clamping mechanism, moves the clamping plate to clamp the steel plate placed above it, preventing the steel plate from shifting during cutting and thus avoiding inaccurate cutting position, effectively improving cutting accuracy and placement stability.

[0017] 3. In this steel plate cutting device, the filter screen 204 is detachably connected to the inside of the filter frame 203. After long-term use, when the filter screen ages, the filter frame 203 can be slid through multiple pull slots 202 by manually pulling forward the handle 205. This allows for the replacement of the filter screen 204 inside the filter frame 203. The operation is simple and convenient. Attached Figure Description
