The ring track is cut by manually pushing the steel plate or adjusting the position of the cutting equipment. During manual operation, it is difficult to ensure the uniformity of the cutting track, which can easily lead to deviations in the ring size and affect subsequent assembly and use. Summary of the Invention

[0009] Preferably, the fixing component further includes multiple magnets, which are distributed at intervals along the circumference of the rotating support platform.

Detailed Implementation

[0015] refer to Figure 1-3 This invention proposes a cooperative fixed-type automatic ring plate cutting device for cutting steel plates. Its components work collaboratively to achieve ring cutting of the steel plate. The specific structure includes: Frame 1 serves as the mounting base for the entire device, supporting and fixing the main components of the device to ensure that each component maintains a relatively fixed positional relationship during operation, providing stable support for the cutting operation.

[0016] Cutting unit 2 is fixedly installed on frame 1 and is used to perform steel plate cutting operations. Its installation position is fixed to ensure that the position of the cutting end does not shift during the cutting process and to ensure the stability of the cutting trajectory.

[0017] The rotating bearing platform 3 is rotatably mounted on the frame 1. The rotating bearing platform 3 has an upward bearing surface, which is used to place the steel plate to be cut. The rotating bearing platform 3 can rotate around its own rotation axis, driving the steel plate placed on the bearing surface to rotate synchronously, providing power support for the formation of the circular cutting trajectory.

[0018] The fixing component 4 is installed on the rotating support table 3. The fixing component 4 can press the steel plate tightly against the support surface. Its function is to limit the displacement of the steel plate during rotation and cutting, ensure that the steel plate rotates synchronously with the rotating support table 3, and avoid the steel plate loosening from affecting the cutting accuracy.

[0019] The cutting unit 2 is located above the bearing surface, and the cutting unit 2 is offset in the horizontal direction relative to the rotation axis of the rotating bearing table 3. This offset setting creates a fixed distance between the cutting end of the cutting unit 2 and the rotation axis of the rotating bearing table 3, so that an annular cutting trajectory corresponding to the distance can be formed on the steel plate as the steel plate rotates with the rotating bearing table 3, thus completing the cutting of the annular plate.

[0020] The cutting unit 2 includes a plasma cutter 21. A support rod is fixedly installed on the frame 1, with one end of the support rod fixedly connected to the frame 1. The support rod is used to fix and support the plasma cutter 21, ensuring the installation stability of the plasma cutter 21. The plasma cutter 21 is fixedly installed on the other end of the support rod, with the cutting torch of the plasma cutter 21 vertically downwards towards the bearing surface. The cutting torch is aligned with the steel plate on the bearing surface, ensuring that the cutting operation can accurately act on the surface of the steel plate and achieve effective cutting of the steel plate.

[0021] The fixing component 4 includes multiple clamping units 41, which are evenly distributed along the circumference of the rotating bearing platform 3. The multiple clamping units 41 can work together to press the steel plate onto the bearing surface. The evenly distributed arrangement ensures that the clamping force at each position on the edge of the steel plate is consistent, further improving the stability of the steel plate fixing and avoiding displacement caused by uneven local force on the steel plate.

[0022] Each clamping unit 41 includes a fixing block 411, a clamping screw 412, a handle 413, and a pressure block 414. The fixing block 411 is fixedly connected to the bearing surface of the rotating bearing platform 3 and is used to provide installation support for the clamping screw 412. A vertical through-hole is provided on the fixing block 411. The clamping screw 412 passes through the threaded hole and is threadedly engaged with the threaded hole. The threaded engagement structure enables the clamping screw 412 to move up and down along the threaded hole. The handle 413 is fixedly connected to one end of the clamping screw 412 and is used for the operator to hold and rotate it to adjust the height of the clamping screw 412. The pressure block 414 is fixedly connected to the other end of the clamping screw 412 and is used to directly contact the edge of the steel plate and apply clamping force. When the handle 413 is rotated, the clamping screw 412 can move up and down along the threaded hole, thereby driving the pressure block 414 to press against or disengage from the edge of the steel plate, realizing the fixing and loosening of the steel plate, which facilitates the placement of the steel plate to be cut and the removal of the finished product after cutting.

[0023] The fixing component 4 also includes multiple magnets 42, which are distributed circumferentially along the rotating support platform 3. Each magnet 42 is mounted one-to-one on a multiple pressure block 414, and the upper surface of each magnet 42 is parallel to the bearing surface. The magnets 42 magnetically attract the steel plate, working in conjunction with the clamping unit 41 to further enhance the fixing effect between the steel plate and the rotating support platform 3, preventing warping or displacement of the steel plate during rotation, and adapting to the fixing requirements of steel plates of different thicknesses.

[0024] The rotating support platform 3 has multiple slag discharge holes 5 arranged in a ring array. All the slag discharge holes 5 penetrate the rotating support platform 3. The upper surface of the frame 1 is flat. During the process of the plasma cutting machine 21 cutting the steel plate, the waste slag generated can fall onto the frame 1 through the multiple slag discharge holes 5, avoiding the accumulation of waste slag on the support surface of the rotating support platform 3, preventing the waste slag from affecting the cutting of the steel plate, and facilitating the subsequent collection and cleaning of the waste slag.

[0025] Multiple slag discharge holes 5 and multiple clamping units 41 are evenly distributed around the center along the same inner circumference, alternating and at equal intervals, and are distributed in a centrally symmetrical manner. This distribution method ensures that the rotating bearing platform 3 is subjected to uniform force, avoids rotational instability caused by local weight concentration, and ensures that the waste slag can be discharged evenly without affecting the normal operation of the clamping unit 41.

[0026] The annular plate cutting device also includes a drive unit, which provides power for the rotation of the rotating support table 3. The drive unit includes a motor and a transmission shaft 6. The motor is fixedly installed inside the frame 1, which provides installation space for the motor and also protects it from damage caused by waste or external debris generated during the cutting process. One end of the transmission shaft 6 is fixedly connected to the output end of the motor to transmit the power output by the motor. The other end of the transmission shaft 6 is fixedly connected to the bottom center of the rotating support table 3, so that the power output by the motor can be accurately transmitted to the rotating support table 3 through the transmission shaft 6, driving the rotating support table 3 to rotate at a constant speed around its own axis, ensuring the stability of the steel plate rotation speed, and thus ensuring the uniformity and accuracy of the annular cutting trajectory.

[0027] The above description is only a preferred embodiment 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.
