[0002] In the field of modern daily-use metal product production, metal sheet cutting is a crucial basic process. With the continuous improvement of people's living standards, the demand for daily-use metal products is becoming increasingly diverse. From simple and practical kitchen utensils to exquisitely shaped home decorations, the product variety is endless, which poses higher requirements for the metal sheet cutting process.

[0003] The patent with the publication number CN217571071U relates to a metal sheet cutting device with relatively high safety. This patent provides such a metal sheet cutting device, which includes an installation frame, a cutting machine, a collection box, a rubber frame, an observation window, a movable plate, an elastic rope, etc. The rear side of the inner top of the installation frame is connected with a cutting machine, the lower part of the installation frame is slidably connected with a collection box for collecting slag, both the middle parts of the left and right sides of the installation frame are connected with rubber frames, the upper part of the front side of the installation frame is connected with an observation window, both the left and right sides of the front side of the installation frame are rotatably connected with movable plates, and elastic ropes are connected between the lower parts of the front sides of the movable plates and the installation frame. Under the action of the installation frame, this device can prevent the sparks and slag generated during cutting from contacting people and causing damage to people, thus protecting people. However, during the process of cutting the metal plate, workers need to manually push the metal sheet for cutting, and workers need to frequently adjust the position of the metal sheet, which is likely to lead to a decrease in the cutting efficiency of workers. Therefore, a metal sheet cutting device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a metal sheet cutting device in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A metal sheet cutting device includes a cutting table.

The inner wall of the baffle is rotationally connected to the lead screw. The surface of the push plate is slidably connected to the inner wall of the baffle. The front part of the inclined plate one is slidably connected to the inner wall of the baffle. The bottom of the inclined plate one is in contact with the top of the inclined plate two. When starting to cut the metal sheet, first place the metal sheet on the top of the cutting table, which can automatically push the metal sheet moving on the surface of the cutting table, and can realize a continuous and fast cutting process, without the need for manual frequent adjustment and pushing of the metal sheet, saving manpower and time, and greatly improving the cutting efficiency. At the same time, it can avoid the situation that the metal sheet will deviate due to the cutting force or vibration during the cutting process. It can also make the pressure roller generate pressure on the metal sheet, thereby improving the neatness of the metal sheet cutting. At the same time, it can also fixedly clamp the metal according to the width of the metal sheet, further improving the stability of the metal sheet during the cutting process.

[0006] Preferably, the protection device includes a sliding groove fixedly connected to the bottom of the cutting table. The bottom of the push plate is fixedly connected to an L-shaped long plate. The bottom of the cutting table is fixedly connected to a sleeve. The circumferential surface of the sleeve is rotationally connected to a rotating frame through a torsion spring. The inner wall of the rotating frame is fixedly connected to a fixed rod, and the front of the fixed rod is fixedly connected to a protective cover. The bottom of the cutting table is fixedly connected to a first fixing block. The inner wall of the first fixing block is slidably connected to a second sliding rod through a spring. The rear of the second sliding rod is fixedly connected to a limiting plate. The inner wall of the sliding groove is in contact with the surface of the L-shaped long plate, and the rear of the limiting plate is in contact with the front of the protective cover. During the process of pushing the metal sheet to move, the fixed rod rotates to drive the protective cover to rotate, so that the protective cover can be opened. Thus, when the device is not in use, the blade of the cutting machine can be protected to prevent the blade from being exposed, which is likely to cause scratches or cuts to the staff. Furthermore, the safety of the device during use can be improved, and the risk of accidents to personnel can be reduced. At the same time, the protective cover can be limited to prevent the protective cover from resetting and rotating back due to the vibration generated during the operation of the device during cutting, which may cause the protective cover to collide with the metal sheet during cutting and prevent normal cutting.

[0007] Preferably, the collection device includes a collection box fixedly connected to the bottom of the cutting table.

The inner wall of the collection box is in contact with the bottom of the leakage plate, and the left side of the arc-shaped plate is in contact with the right side of the force-receiving block. The top of the cutting table is in contact with the circumferential surface of the transmission wheel. It can collect the iron filings generated during the cutting process to prevent the iron filings from entering the gaps, bearings, transmission components, etc. of the cutting device, resulting in increased equipment wear, jamming, or even failure. It can also flatten the iron filings falling into the collection box to prevent the iron filings from accumulating at the same position at the feeding port of the collection box, which may cause the iron filings to be unevenly distributed inside the collection box, thereby reducing the capacity of the collection box to hold the iron filings. At the same time, it can clean the metal iron filings flying on the surface of the cutting table to avoid the need for workers to clean them manually after cutting the metal iron sheet, thereby reducing the labor intensity of the workers and improving the cutting efficiency of the workers.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. The metal sheet cutting device, through the coordinated operation of the cutting table, baffle, motor, lead screw, sliding block, push plate, first inclined plate, fixed table, first sliding rod, L-shaped plate, second inclined plate, elastic telescopic rod, clamping plate, pressure roller, and cutting machine. When starting to cut the metal sheet, first place the metal sheet on the top of the cutting table, which can automatically push the metal sheet moving on the surface of the cutting table, enabling a continuous and fast cutting process. There is no need for manual frequent adjustment and pushing of the metal sheet, saving manpower and time, greatly improving the cutting efficiency. At the same time, it can prevent the metal sheet from shifting due to cutting force or vibration during the cutting process.

Thus, when the device is not in use, the blade of the cutting machine can be protected to prevent the blade from being exposed, which is likely to cause scratches or cuts to the staff, thereby improving the safety of the device during use and reducing the risk of accidents to personnel. At the same time, the protective cover can be limited to prevent the protective cover from resetting and rotating back due to the vibration generated during the operation of the device during cutting, which may cause the protective cover to collide with the metal sheet during cutting and result in abnormal cutting.

[0010] 3. The metal sheet cutting device, through the coordinated operation of the collection box, inclined hopper, rotating plate, arc-shaped plate, connecting rod, leakage plate, stress block, second fixed block, cleaning roller, and transmission wheel, can collect the iron filings generated during the cutting process, preventing the iron filings from entering the gaps, bearings, transmission components, etc. of the cutting device, which may lead to increased equipment wear, jamming, or even failure. It can also flatten the iron filings falling into the collection box, thus preventing the iron filings from accumulating at the same position at the feeding port of the collection box, resulting in uneven distribution of the iron filings inside the collection box and reducing the capacity of the collection box to hold the iron filings. At the same time, it can clean the metal iron filings flying on the surface of the cutting table, avoiding the need for workers to clean them manually after cutting the metal sheet, thereby reducing the labor intensity of the workers and improving the cutting efficiency of the workers.

Detailed implementation manners

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1 - 9, an embodiment of the present invention is: a metal sheet cutting device, including a cutting table 1, a baffle 2 is fixedly connected to the top of the cutting table 1, a motor 3 is fixedly connected to the top of the cutting table 1, an output end of the motor 3 is fixedly connected to a lead screw 4, a sliding block 5 is movably connected to the circumferential surface of the lead screw 4, a push plate 6 is fixedly connected to the front of the sliding block 5. When starting to cut the metal sheet, first place the metal sheet on the top of the cutting table 1. At this time, the motor 3 is started, and the motor 3 drives the lead screw 4 to rotate. The screw block inside the sliding block 5 contacts the thread on the surface of the lead screw 4 when the lead screw 4 rotates, thereby driving the sliding block 5 to move to the right. The sliding block 5 moving to the right drives the push plate 6 to move to the right, so that the metal sheet on the surface of the cutting table 1 can be automatically pushed to move, and a continuous and fast cutting process can be realized. There is no need for manual frequent adjustment and pushing of the metal sheet, saving manpower and time, and greatly improving the cutting efficiency. A first inclined plate 7 is fixedly connected to the rear of the push plate 6, a fixed table 8 is fixedly connected to the top of the baffle 2, a first sliding rod 9 is slidably connected to the inner wall of the fixed table 8 through a spring, an L-shaped plate 10 is fixedly connected to the circumferential surface of the first sliding rod 9, a second inclined plate 11 is fixedly connected to the front of the L-shaped plate 10, a cutting machine 12 is installed at the bottom of the cutting table 1, a protection device 13 for protecting the safety of workers is provided on the inner wall of the cutting table 1, a collecting device 14 for collecting cutting debris is provided at the bottom of the cutting table 1, an elastic telescopic rod 15 is fixedly connected to the front of the push plate 6, a clamping plate 16 is fixedly connected to the circumferential surface of the telescopic end of the elastic telescopic rod 15, a pressing roller 17 is fixedly connected to the bottom of the clamping plate 16, the inner wall of the baffle 2 is rotatably connected to the lead screw 4, the surface of the push plate 6 is slidably connected to the inner wall of the baffle 2, the front of the first inclined plate 7 is slidably connected to the inner wall of the baffle 2, the bottom of the first inclined plate 7 contacts the top of the second inclined plate 11. At the same time, the movement of the push plate 6 drives the first inclined plate 7 to move backward. The movement of the first inclined plate 7 contacts the second inclined plate 11 and generates a downward extrusion force on the second inclined plate 11, causing the second inclined plate 11 to move downward. The downward movement of the second inclined plate 11 drives the L-shaped plate 10 to move downward, and the downward movement of the L-shaped plate 10 drives the pressing roller 17 to move downward, so that the metal sheet can be prevented from shifting due to the cutting force or vibration during the cutting process, and the pressing roller 17 can also generate pressure on the metal sheet, thereby improving the neatness of the metal sheet cutting. At the same time, during the process of placing the metal sheet, by pulling the clamping plate 16, the elastic telescopic rod 15 is stretched, so that the metal can be fixedly clamped according to the width of the metal sheet, further improving the stability of the metal sheet during the cutting process.

[0015] The protection device 13 includes a sliding groove 131 fixedly connected to the bottom of the cutting table 1. The bottom of the push plate 6 is fixedly connected with an L-shaped long plate 132. The bottom of the cutting table 1 is fixedly connected with a sleeve 133. The circumferential surface of the sleeve 133 is rotationally connected with a rotating frame 134 through a torsion spring. The inner wall of the rotating frame 134 is fixedly connected with a fixing rod 135. The front part of the fixing rod 135 is fixedly connected with a protective cover 136. During the process of pushing the metal sheet to move, the movement of the push plate 6 drives the L-shaped long plate 132 to move. During the movement of the L-shaped long plate 132, it will contact the rotating frame 134 and push the rotating frame 134 to rotate 180 degrees clockwise. The rotation of the rotating frame 134 drives the fixing rod 135 to rotate, and the rotation of the fixing rod 135 drives the protective cover 136 to rotate, so that the protective cover 136 can be opened. Furthermore, when the device is not in use, the blade of the cutting machine 12 can be protected to prevent the blade from being exposed, which is likely to cause scratches or cuts to the staff. Therefore, the safety of the device during use can be improved, and the risk of accidents to personnel can be reduced. The bottom of the cutting table 1 is fixedly connected with a first fixing block 137. The inner wall of the first fixing block 137 is slidably connected with a second sliding rod 138 through a spring. The rear part of the second sliding rod 138 is fixedly connected with a limiting plate 139. The inner wall of the sliding groove 131 is in contact with the surface of the L-shaped long plate 132, and the rear part of the limiting plate 139 is in contact with the front part of the protective cover 136. At the same time, the rotation of the protective cover 136 will contact the limiting plate 139. When the protective cover 136 rotates 180 degrees, the limiting plate 139 will no longer be in contact with the protective cover 136. Then, the second sliding rod 138 moves backward by the compression of the spring, and the backward movement of the second sliding rod 138 drives the limiting plate 139 to move backward, so as to limit the protective cover 136 and prevent the protective cover 136 from resetting and rotating back due to the vibration generated during the operation of the device during cutting, which may cause the protective cover 136 to collide with the metal sheet during cutting and prevent normal cutting.

[0016] Working principle: When starting to cut the metal sheet, first place the metal sheet on the top of the cutting table 1. At this time, the motor 3 starts. The start of the motor 3 drives the screw rod 4 to rotate. The rotation of the screw rod 4 causes the slider inside the sliding block 5 to contact the thread on the surface of the screw rod 4, thereby driving the sliding block 5 to move to the right. The movement of the sliding block 5 to the right drives the push plate 6 to move to the right, so that the metal sheet on the surface of the cutting table 1 can be automatically pushed to move, enabling a continuous and rapid cutting process. There is no need for manual frequent adjustment and pushing of the metal sheet, saving manpower and time, and greatly improving the cutting efficiency. At the same time, the movement of the push plate 6 drives the inclined plate 1 7 to move backward. The movement of the inclined plate 1 7 contacts the inclined plate 2 11 and generates a downward extrusion force on the inclined plate 2 11, causing the inclined plate 2 11 to move downward. The downward movement of the inclined plate 2 11 drives the L-shaped plate 10 to move downward, and the downward movement of the L-shaped plate 10 drives the pressure roller 17 to move downward, which can prevent the metal sheet from shifting due to the cutting force or vibration during the cutting process. It can also make the pressure roller 17 exert pressure on the metal sheet, thereby improving the neatness of the metal sheet cutting. At the same time, during the process of placing the metal sheet, by pulling the clamping plate 16, the elastic telescopic rod 15 is stretched, so that the metal can be fixedly clamped according to the width of the metal sheet, further improving the stability of the metal sheet during the cutting process.

[0017] During the process of pushing the metal sheet to move, the movement of the push plate 6 drives the L-shaped long plate 132 to move. During the movement of the L-shaped long plate 132, it contacts the rotating frame 134 and pushes the rotating frame 134 to rotate 180 degrees clockwise. The rotation of the rotating frame 134 drives the fixed rod 135 to rotate, and the rotation of the fixed rod 135 drives the protective cover 136 to rotate, so that the protective cover 136 can be opened. Thus, when the device is not in use, the blade of the cutting machine 12 can be protected to prevent the blade from being exposed, which is likely to cause scratches or cuts to the staff, and can improve the safety of the device during use and reduce the risk of accidents to personnel. At the same time, the rotation of the protective cover 136 contacts the limit plate 139. When the protective cover 136 rotates 180 degrees, the limit plate 139 will no longer contact the protective cover 136. Then, the sliding rod 2 138 moves backward through the spring compression, and the backward movement of the sliding rod 2 138 drives the limit plate 139 to move backward, which can limit the protective cover 136 to prevent the protective cover 136 from resetting and rotating back due to the vibration generated during the operation of the device during the cutting process, resulting in a collision between the protective cover 136 and the metal sheet during the cutting of the device and causing the cutting to be unable to proceed normally.

[0018] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, the collection device 14 includes a collection box 141. The collection box 141 is fixedly connected to the bottom of the cutting table 1. An inclined hopper 142 is fixedly connected to the right side of the collection box 141. A rotating plate 143 is rotatably connected to the circumferential surface of the rotating frame 134. An arc-shaped plate 144 is fixedly connected to the bottom of the rotating plate 143. A connecting rod 145 is slidably connected to the inner wall of the collection box 141 through a spring. A leakage plate 146 is fixedly connected to the left side of the leakage plate 146. When the protection of the cutting machine 12 is released, the rotation of the rotating frame 134 drives the rotation of the rotating plate 143. The rotation of the rotating plate 143 drives the rotation of the arc-shaped plate 144. The rotation of the arc-shaped plate 144 generates a leftward squeezing force on the stress block 147, causing the stress block 147 to move leftward. The leftward movement of the stress block 147 drives the leftward movement of the connecting rod 145. The movement of the connecting rod 145 drives the movement of the leakage plate 146, so as to collect the iron filings generated during the cutting process, prevent the iron filings from entering the gaps, bearings, transmission components, etc. of the cutting device, resulting in increased equipment wear, jamming or even failure, and can also push the iron filings falling in the collection box 141 flat, thereby avoiding the iron filings from accumulating at the same position at the feeding port of the collection box 141, resulting in the iron filings not being evenly distributed inside the collection box 141, and further causing the reduction of the iron filing capacity of the collection box 141. A stress block 147 is fixedly connected to the right side of the connecting rod 145. A second fixing block 148 is fixedly connected to the left side of the push plate 6. A cleaning roller 149 is rotatably connected to the inner wall of the second fixing block 148. A transmission wheel 1410 is rotatably connected to the central axis of the cleaning roller 149. The inner wall of the collection box 141 is in contact with the bottom of the leakage plate 146. The left side of the arc-shaped plate 144 is in contact with the right side of the stress block 147. The top of the cutting table 1 is in contact with the circumferential surface of the transmission wheel 1410. At the same time, when pushing the metal sheet, the movement of the push plate 6 drives the movement of the second fixing block 148. The movement of the second fixing block 148 drives the movement of the cleaning roller 149. The movement of the cleaning roller 149 drives the movement of the transmission wheel 1410. During the movement of the transmission wheel 1410, it will contact the top of the cutting table 1, thereby generating frictional force to drive the rotation of the transmission wheel 1410. The rotation of the transmission wheel 1410 drives the rotation of the cleaning roller 149, so as to clean the metal iron filings flying on the surface of the cutting table 1, avoid the need for workers to clean them manually after cutting the metal iron sheet, thereby reducing the labor intensity of workers and improving the cutting efficiency of workers.

[0019] Working principle: When the protection of the cutting machine 12 is released, the rotating frame 134 rotates to drive the rotating plate 143 to rotate. The rotation of the rotating plate 143 drives the arc-shaped plate 144 to rotate. The rotation of the arc-shaped plate 144 generates a leftward squeezing force on the force-bearing block 147, causing the force-bearing block 147 to move leftward. The leftward movement of the force-bearing block 147 drives the connecting rod 145 to move leftward. The movement of the connecting rod 145 drives the leakage plate 146 to move, so as to collect the iron filings generated during the cutting process, prevent the iron filings from entering the gaps, bearings, transmission components, etc. of the cutting device, resulting in increased equipment wear, jamming or even failure. It can also flatten the iron filings falling in the collection box 141, and further prevent the iron filings from accumulating at the same position at the feeding port of the collection box 141, resulting in the iron filings being unable to be evenly distributed inside the collection box 141, thus reducing the iron filing accommodation capacity of the collection box 141. At the same time, when pushing the metal sheet, the push plate 6 moves to drive the second fixing block 148 to move. The movement of the second fixing block 148 drives the cleaning roller 149 to move. The movement of the cleaning roller 149 drives the transmission wheel 1410 to move. During the movement, the transmission wheel 1410 contacts the top of the cutting table 1, and then generates a frictional force to drive the transmission wheel 1410 to rotate. The rotation of the transmission wheel 1410 drives the cleaning roller 149 to rotate, so as to clean the metal iron filings flying on the surface of the cutting table 1, avoid the need for workers to clean them manually after cutting the metal sheet, thereby reducing the labor intensity of the workers and improving the cutting efficiency of the workers.

[0020] The present invention provides a metal sheet cutting device. There are many methods and ways to specifically implement this technical solution. The above description is only a preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using the prior art.
