A track is fixedly installed on the left side of the upper surface of the cutting table. A rack is slidably mounted on the track. A gripper is fixedly mounted on the outer side of the upper surface of the rack.

[0008] Preferably, when the rotating rod is in a horizontal state, the lower part of the cutting disc extends into the cutting groove.

[0009] Preferably, the protective cover is a hollow semi-circular shape, and the upper part of the cutting disc is inside the protective cover.

[0010] Preferably, the rack slides on the track, and the rack meshes with the gear.

[0011] Preferably, a centimeter scale is provided on the right side of the cutting groove on the outer side of the upper surface of the cutting table.

[0012] Preferably, the cutting groove extends through the outer surface of the cutting table, and the bottom of the cutting groove is inclined with a lower outer horizontal height and a higher inner horizontal height.

[0013] Preferably, the track includes a track groove and a spring. The track groove is formed on the upper surface of the track and has an inner end sealed groove structure. A spring is fixedly arranged between the inner end of the track groove and the rack.

[0014] Preferably, the track groove is convex in shape, and the lower part of the rack matches the track groove, with the lower part of the rack sliding within the track groove.

[0015] Preferably, when the spring is in its naturally extended state, the rotating rod is tilted with the outer end higher than the inner end, and at this time the horizontal height of the cutting disc is higher than the horizontal height of the upper surface of the cutting table.

[0016] Preferably, a protective component is fixedly installed on the left side of the upper surface of the cutting table. The protective component includes an L-shaped bracket, a protective plate, and a handle. The L-shaped bracket is fixedly installed on the left side of the outer surface of the cutting table. The protective plate is installed through the center of the upper surface of the L-shaped bracket. The handle is fixedly installed on the upper surface of the protective plate.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] 1. This utility model, equipped with a pin, gear, track, and rack, allows for cutting of steel plates. When cutting, the operator grasps the outer end of the rotating rod and rotates it upwards, raising the cutting disc to a height higher than the upper surface of the cutting table. The steel plate to be cut is then placed on the cutting table, with the cutting point directly below the cutting disc. The operator grasps the gripper lever, turns on the motor, and the motor drives the cutting disc to rotate. Pushing the gripper lever inwards causes the rack to drive the gear, which in turn drives the pin to rotate the rotating rod. The cutting disc cuts the steel plate. The gripper lever controls the rotation of the rotating rod to achieve cutting. The gripper lever is positioned far from the cutting disc to prevent metal shavings from injuring the operator's hands, ensuring safety.

[0019] 2. This utility model, by setting a centimeter scale, allows the distance between the cutting point of the cutting disc and the end of the steel plate to be read through the centimeter scale when cutting the steel plate. This enables the control of the length of the cut steel plate and increases the convenience of cutting.

[0020] 3. This utility model has a cutting groove that runs through the outer surface of the cutting table. The bottom of the cutting groove is inclined with a lower horizontal height at the outer end and a higher horizontal height at the inner end. When metal chips generated from cutting the steel plate fall into the cutting groove, they will move outward along the bottom of the cutting groove under the action of gravity until they fall from the outer end of the cutting groove. This can prevent metal chips from clogging the cutting groove and facilitate the collection of metal chips.

[0021] 4. This utility model features a track groove and a spring. The track groove ensures the stability of the rack sliding within it. When the spring is in its natural extended state, the rotating rod is tilted with the outer end higher than the inner end, making it convenient to place the steel plate to be cut under the cutting disc without manually rotating the rotating rod. The operation is simple and convenient. During cutting, pulling the gripper rod outward overcomes the spring force, causing the rack to drive the gear to rotate, thereby driving the rotating rod to rotate and achieving the cutting effect.

[0022] 5. This utility model, by incorporating a protective component, allows for easy cutting of steel plates. When the worker stands on the left side of the cutting table, they need to grasp the handle and operate the rotating rod to make the cut. However, by installing a protective component on the left side of the upper surface of the cutting table, the steel plate to be cut is placed on the cutting table. By pulling the handle upwards, the handle moves the protective plate upwards, allowing the steel plate to pass under the protective plate. Once the cutting position is determined, the handle is released, and the protective plate, under gravity, moves downwards and adheres to the upper surface of the steel plate to be cut. The protective plate protects the worker standing on the left side of the cutting table, preventing hand injuries from flying metal during cutting. Attached Figure Description

[0030] Example:

[0031] like Figures 1-4 As shown, an embodiment of this utility model provides a steel plate processing protective device, including a cutting table 1. A cutting groove 101 is provided in the center of the outer surface of the cutting table 1. A concave frame 2 is fixedly provided on the inner side of the upper surface of the cutting table 1. A pin 3 is rotatably provided on the concave frame 2. A rotating rod 4 is fixedly provided on the pin 3. A gear 301 is fixedly provided on the left end of the pin 3. A motor 5 is fixedly provided on the outer end of the left side surface of the rotating rod 4. A cutting disc 6 is installed at the output end of the motor 5. A protective cover 7 is fixedly provided on the right side surface of the rotating rod 4. A track 8 is fixedly provided on the left side of the upper surface of the cutting table 1. A rack 9 is slidably provided on the track 8. A gripper rod 901 is fixedly provided on the outer side of the upper surface of the rack 9.

[0032] The system is equipped with a pin 3, gear 301, track 8, and rack 9. When cutting a steel plate, the operator grasps the outer end of the rotating rod 4 and rotates it upwards, making the horizontal height of the cutting disc 6 higher than the upper surface of the cutting table 1. Then, the steel plate to be cut is placed on the cutting table 1, with the cutting point directly below the cutting disc 6. The operator grasps the gripper rod 901 and turns on the motor 5. The motor 5 drives the cutting disc 6 to rotate, pushing the gripper rod 901 inwards. The rack 9 drives the gear 301 to rotate, causing the pin 3 to drive the rotating rod 4 to rotate. The cutting disc 6 cuts the steel plate. The gripper rod 901 controls the rotation of the rotating rod 4 to achieve the cutting. The gripper rod 901 is positioned far from the cutting disc 6 to prevent metal shavings from injuring the operator's hands during cutting, ensuring safety.

[0033] In this embodiment, when the rotating rod 4 is in a horizontal state, the lower part of the cutting disc 6 extends into the cutting groove 101, which facilitates the cutting disc 6 to cut the steel plate placed on the upper surface of the cutting table 1 and spanning the cutting groove 101.

[0034] In this embodiment, the protective cover 7 is a hollow semi-circular shape, and the upper part of the cutting disk 6 is inside the protective cover 7, which facilitates the protective cover 7 to block the metal chips generated during cutting and prevent the metal chips generated during cutting from splashing.

[0035] In this embodiment, the rack 9 slides on the track 8, and the rack 9 meshes with the gear 301, so that the movement of the rack 9 along the track 8 can drive the gear 301 to rotate, thereby achieving the effect of driving the pin 3 and the rotating rod 4 to rotate.

[0036] In this embodiment, a centimeter scale 102 is provided on the right side of the cutting groove 101 on the outer side of the upper surface of the cutting table 1.

[0037] With a centimeter scale 102, when cutting a steel plate, the distance between the cutting point of the cutting disc and the end of the steel plate can be read through the centimeter scale by placing the steel plate on the cutting table. This allows for control over the length of the cut steel plate and increases the ease of cutting.

[0038] In this embodiment, the cutting groove 101 extends through the outer surface of the cutting table 1, and the bottom of the cutting groove 101 is inclined with the outer end being lower than the inner end.

[0039] The cutting groove 101 extends through the outer surface of the cutting table 1, and the bottom of the cutting groove 101 is inclined with the outer end being lower than the inner end. When metal chips generated from cutting the steel plate fall into the cutting groove 101, under the action of gravity, the metal chips will move outward along the bottom of the cutting groove 101 until they fall from the outer end of the cutting groove 101. This can prevent the metal chips from clogging the cutting groove and facilitate the collection of metal chips.

[0040] In this embodiment, the track 8 includes a track groove 801 and a spring 802. The track groove 801 is provided on the upper surface of the track 8, and the track groove 801 has a groove structure with an inner end sealed. The spring 802 is fixedly provided between the inner end of the track groove 801 and the rack 9.

[0041] In this embodiment, the track groove 801 is convex in shape, and the lower part of the rack 9 matches the track groove 801. The lower part of the rack 9 slides in the track groove 801 to ensure the stability of the rack 9 sliding in the track groove 801.

[0042] In this embodiment, when the spring 802 is in a naturally extended state, the rotating rod 4 is tilted with the outer end horizontal height higher than the inner end horizontal height, and at this time the horizontal height of the cutting disk 6 is higher than the horizontal height of the upper surface of the cutting table 1.

[0043] By setting the track groove 801 and the spring 802, the track groove 801 ensures the stability of the rack 9 sliding within it. When the spring 802 is in its natural extended state, the rotating rod 4 is tilted with the outer end higher than the inner end, making it convenient to place the steel plate to be cut under the cutting disc 6 without manually rotating the rotating rod 4 to place the steel plate. The operation is simple and convenient. When cutting, pulling the gripper rod 901 outwards overcomes the elasticity of the spring 802, which causes the rack 9 to drive the gear 301 to rotate, thereby driving the rotating rod 4 to rotate and achieving the cutting effect.

[0044] In this embodiment, a protective component is fixedly installed on the left side of the upper surface of the cutting table 1. The protective component includes an L-shaped bracket 10, a protective plate 1001, and a handle 1002. The L-shaped bracket 10 is fixedly installed on the left side of the outer surface of the cutting table 1. The protective plate 1001 is provided through the center of the upper surface of the L-shaped bracket 10. The handle 1002 is fixedly installed on the upper surface of the protective plate 1001.

[0045] With the addition of a protective component, when cutting a steel plate, the worker stands on the left side of the cutting table 1 and needs to grasp the handle 901 to control the rotating rod 4 to achieve the cut. By setting the protective component on the left side of the upper surface of the cutting table 1, the steel plate to be cut is placed on the cutting table 1, and by pulling the handle 1002 upward, the handle moves the protective plate 1001 upward. The steel plate passes under the protective plate 1001. After the cutting position of the steel plate is determined, the handle 1002 is released, and the protective plate 1001 moves downward under the action of gravity and adheres to the upper surface of the steel plate to be cut. The protective plate 1001 can protect the worker standing on the left side of the cutting table 1 and prevent the worker's hand from being injured by flying metal during the cutting process.

[0046] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
