[0002] Cold-rolled steel sheets are widely used in the fields of automotive parts, home appliances, and steel bars due to their excellent performance and wide applicability. Cold-rolled steel sheets are obtained by further processing of cold-rolled coils. During the processing, through cutting, flattening, finishing and other processes, cold-rolled steel sheet products that meet the requirements can be obtained;

[0003] In the process of preparing cold-rolled steel sheets, the cold-rolled steel coils need to be cut to form cold-rolled steel coils of appropriate lengths before subsequent processing operations are carried out. During cutting, while ensuring that the cutting length is appropriate, it is also necessary to ensure that the end faces after cutting are flat and smooth, thereby ensuring the subsequent processing effect. In the prior art, after cutting, it is necessary to manually perform fine inspections on the cutting length and the effect of the cutting end faces. However, completing the inspection work by manual inspection is time-consuming and labor-intensive, and it is easy for the inspection results to be biased. Summary of the invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a cold-rolled steel plate and its processing system and method, which can automatically detect the cutting length and end face cutting effect of the steel coil, and can automatically grind and remove burrs on the cut end face.

[0005] A cold-rolled steel plate processing system comprises a base plate, a side plate is fixedly connected to the base plate, a clamping plate is slidably connected to the base plate, a longitudinal sliding rod is slidably connected to the base plate, a transverse sliding rod is slidably connected to the longitudinal sliding rod, a connecting frame is fixedly connected to the transverse sliding rod, a moving part is connected to the connecting frame, a detection rod is slidably connected to the moving part, a grinding wheel is rotatably connected to the moving part, and a first compression spring is fixedly connected between the moving part and the detection rod.

[0006] The moving part is slidably connected to the connecting frame, a pressure rod is slidably connected to the moving part, an auxiliary plate B is fixedly connected to the longitudinal sliding rod, the detection rod can contact the auxiliary plate B, and a second compression spring is fixedly connected between the pressure rod and the connecting frame.

[0007] The front side of the detection rod is provided with an arc chamfer.

[0008] It also includes an auxiliary plate A fixedly connected to the auxiliary plate B, and the auxiliary plate A is fixedly connected to a support rod.

[0009] The cold-rolled steel plate processing system is used for a processing method of a cold-rolled steel plate, and the method comprises the following steps:

[0010] Step 1: Place the steel coil on the bottom plate and make one end of the steel coil rest against the vertical plate;

[0011] Step 2: Slide the clamping plate until it cooperates with the side plate to clamp the steel coil;

[0012] Step 3: Slide the pressure rod downward until it presses against the upper side of the steel coil;

[0013] Step 4: Use a cutting knife to cut the steel coil at a suitable length;

[0014] Step 5: operate the longitudinal slide bar to slide on the bottom plate and move the longitudinal slide bar to the same position as the target length after the steel coil is cut;

[0015] Step 6: operate the transverse slide bar to slide on the longitudinal slide bar, and detect the cutting and forming effect of the end face of the steel coil by detecting the sliding condition of the rod;

[0016] Step 7: If the sliding of the detection rod is caused by a small burr, continue to slide the moving part until the grinding wheel contacts the burr, and use the rotating grinding wheel to remove the burr;

[0017] Step 8: If the sliding of the detection rod is caused by a large protrusion that cannot be removed by grinding, re-cut the position to ensure the cutting effect of the finished product;

[0018] Step 9: After the cutting and end surface inspection operations are completed, the steel coil is cold rolled, annealed, flattened and refined to form the steel coil into a finished cold rolled steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-8 As shown:

[0029] A cold-rolled steel plate processing system comprises a base plate 102, a side plate 105 is fixedly connected to the base plate 102, a clamping plate 201 is slidably connected to the base plate 102, a longitudinal slide bar 301 is slidably connected to the base plate 102, a transverse slide bar 402 is slidably connected to the longitudinal slide bar 301, a connecting frame 401 is fixedly connected to the transverse slide bar 402, a moving part 501 is connected to the connecting frame 401, a detection rod 502 is slidably connected to the moving part 501, a grinding wheel 504 is rotatably connected to the moving part 501, a first electric push rod capable of pushing the longitudinal slide bar 301 to slide is fixedly connected to the base plate 102, a second electric push rod capable of pushing the transverse slide bar 402 to slide is fixedly connected to the longitudinal slide bar 301, a first motor capable of driving the grinding wheel 504 to rotate is fixedly connected to the transverse slide bar 402, and a first compression spring is fixedly connected between the moving part 501 and the detection rod 502.

[0030] The steel coil is placed on the bottom plate 102, and then the clamping plate 201 is slid to cooperate with the side plate 105 to clamp the steel coil. After the steel coil is clamped and fixed, the steel coil is cut at a suitable length using a cutting knife to obtain a clamped steel coil of the target length. After the cutting operation is completed, the longitudinal slide bar 301 is operated to slide on the bottom plate 102, and then the longitudinal slide bar 301 is moved to the same position as the target length after the steel coil is cut. At this time, the detection rod 502 should be in a position that can just contact the end face of the cut steel coil, and then the transverse slide bar 402 is slid on the longitudinal slide bar 301, so that the detection rod 502 is gradually Approaching the steel coil, so that the detection rod 502 gradually passes through all positions of the cut end face of the steel coil. During this process, the staff can observe whether the detection rod 502 slides on the moving part 501 to overcome the elastic force of the first compression spring, so as to accurately understand whether there are abnormal protrusions or burrs on the cut end face of the steel coil, and then detect the cutting effect of the steel coil. At the same time, by observing whether the detection rod 502 can smoothly overlap with the end face after sliding the longitudinal slide rod 301, it is possible to further detect whether the cutting length of the steel coil meets the target requirements, so as to avoid the situation where the cutting length of the steel coil is deviated due to program errors and affects the subsequent actual use.

[0031] If the detection rod 502 can smoothly overlap with the end face after sliding the longitudinal slide bar 301, but the detection rod 502 adaptively slides on the moving part 501 when the moving part 501 is continuously slid, the staff can observe the sliding position of the detection rod 502. If the sliding of the detection rod 502 is caused by a small burr, the grinding wheel 504 can be operated to rotate on the moving part 501, and the rotating grinding wheel 504 can be made to contact the burr position, so as to grind the burr position with the rotating grinding wheel 504, thereby improving the smooth and flat effect of the end face. If the sliding of the detection rod 502 is caused by a large protrusion that cannot be removed by grinding, the position can be cut again, thereby further ensuring the cutting effect of the finished product.

[0032] The sliding condition of the detection rod 502 can be monitored by the naked eye of the staff, or by connecting a displacement sensor to the moving part 501 by tightening bolts, and fixing the moving end of the displacement sensor to the detection rod 502. When the detection rod 502 moves, the displacement sensor can promptly convert the movement into an electrical signal for transmission, so that the staff can arrive at the scene in time, determine the cause of the sliding of the detection rod 502, and thus determine the subsequent processing method, which brings convenience to actual use.

[0033] like Figure 3-8 As shown:

[0034] The moving part 501 is slidably connected to the connecting frame 401, and a pressure rod 503 is slidably connected to the moving part 501. An auxiliary plate B302 is fixedly connected to the longitudinal sliding rod 301. The detection rod 502 can contact the auxiliary plate B302, and a second compression spring is fixedly connected between the pressure rod 503 and the connecting frame 401.

[0035] Normally, the pressure rod 503 is pressed against the moving part 501 by the elastic force of the second compression spring, so that the detection rod 502 is pressed against the auxiliary plate B302. In the process of sliding the longitudinal slide bar 301, the auxiliary plate B302 is moved to a position that coincides with the target length of the end face of the cut steel coil. At this time, if the cutting effect is perfect, the detection rod 502 should be able to just contact the end face of the steel coil after cutting. Then, the detection rod 502 can be used to detect the end face of the steel coil after cutting by sliding the transverse slide bar 402. During the detection process, if the detection rod 502 slides, and the staff observes that the sliding of the detection rod 502 is small, The burr can be removed by grinding with the rotating grinding wheel 504, and the detection rod 502 can continue to slide adaptively on the moving part 501 by sliding the moving part 501. When the detection rod 502 slides to the maximum stroke, the burr will push the moving part 501 outward, so that the pressure rod 503 can slide on the connecting frame 401 to overcome the elastic force of the second compression spring, so that the moving part 501 moves away from the burr position first, and then as the horizontal sliding rod 402 continues to slide until it is in contact with the grinding wheel 504 and the burr position, the rotating grinding wheel 504 can be used to grind the position to complete the operation of perfecting the cutting effect;

[0036] That is, the device can make the detection rod 502 pass through the burr position smoothly by continuously sliding the transverse slide rod 402 and can remove the burr smoothly by rotating the grinding wheel 504, thus completing an efficient processing operation.

[0037] like Figure 5-6 As shown:

[0038] The front side of the detection rod 502 is provided with an arc chamfer.

[0039] The arc chamfer is set so that when the detection rod 502 contacts the burr and as the moving part 501 continues to slide, the arc chamfer on the detection rod 502 can further smoothly make the detection rod 502 pass the burr position, bringing convenience to subsequent processing work.

[0040] like Figure 3 and Figure 8 As shown:

[0041] It also includes an auxiliary plate A303 fixedly connected to the auxiliary plate B302, and a support rod 304 is fixedly connected to the auxiliary plate A303.

[0042] When the grinding wheel 504 is needed to grind the burrs, as the grinding wheel 504 continues to slide, the detection rod 502 will contact the auxiliary plate A303. At this time, the pressure rod 503 will be tightly pressed against the moving part 501 by the elastic force of the second compression spring, so that the detection rod 502 is tightly pressed against the auxiliary plate A303, thereby ensuring the stability of the subsequent grinding process of the grinding wheel 504. When the detection rod 502 contacts the auxiliary plate A303, the pressure rod 503 contacts the support rod 304, and then the support rod 304 is used to further restrict the pressure rod 503, thereby further preventing the grinding wheel 504 from shaking during the grinding process, thereby ensuring the stability of the grinding work of the grinding wheel 504.

[0043] In actual use, the lengths of the support rod 304 and the auxiliary plate A303 are both as long as shown in the figure, ensuring that when the detection rod 502 contacts the auxiliary plate A303, the support rod 304 can just contact the pressure rod 503, providing stability for the grinding work. The auxiliary plate A303 ensures that during the subsequent sliding process of the transverse sliding rod 402, the detection rod 502 can always contact the auxiliary plate A303, further ensuring the smooth progress of the grinding work.

[0044] like Figure 1 As shown:

[0045] The device further comprises a pressing rod 103 which is slidably connected to the bottom plate 102 , and a third electric push rod which can drive the pressing rod 103 to slide is fixedly connected to the bottom plate 102 .

[0046] Before cutting, slide the pressure rod 103 downward so that it rests against the upper side of the cold-rolled steel coil. Use the pressure rod 103 to clamp the steel coil in the vertical direction. Cooperate with the clamping plate 201 and the side plate 105 to fully clamp the cold-rolled steel coil to prevent the steel coil from deviating during cutting or grinding.

[0047] like Figure 1-2 As shown:

[0048] The side plate 105 is provided with a groove A106 , and the clamping plate 201 is provided with a groove B202 . The pressure rod 103 can be inserted into the groove A106 and the groove B202 .

[0049] The arrangement of the groove A106 and the groove B202 enables the pressure rod 103 to slide down to a longer distance during the process of sliding down the pressure rod 103, thereby facilitating the clamping of steel coils of different heights and providing a wider range of application for the equipment.

[0050] like Figure 1-2 As shown:

[0051] The device further comprises a fixing base 101 , to which a bottom plate 102 is rotatably connected, and a second motor capable of driving the bottom plate 102 to rotate is fixedly connected to the fixing base 101 .

[0052] During the cutting operation, coolant can be continuously injected into the cutting position to cool the heat generated during the cutting process and prevent the cold-rolled steel coil from deforming due to overheating during the processing. After the cutting and end face inspection operations are completed, the bottom plate 102 can be operated to rotate on the fixed seat 101 to rotate the steel coil to tilt upward, and then coolant is continuously injected into the end face of the steel coil. At this time, the staff can observe whether there is a bubble position on the end face, determine whether there is a crack on the end face of the steel coil, and further inspect the cutting forming effect.

[0053] like Figure 1 As shown:

[0054] The structure also includes a vertical plate 104 fixed to the bottom plate 102 .

[0055] The vertical plate 104 is provided so that when placing the steel coil, one end of the steel coil can be placed against the vertical plate 104, so that the steel coil is stably and neatly placed on the bottom plate 102, which facilitates the subsequent cutting operation of the steel coil to a suitable length.

[0056] The cold-rolled steel plate processing system is used for a processing method of a cold-rolled steel plate, and the method comprises the following steps:

[0057] Step 1: Place the steel coil on the bottom plate 102 and make one end of the steel coil rest against the vertical plate 104;

[0058] Step 2: Slide the clamping plate 201 until the clamping plate 201 cooperates with the side plate 105 to clamp the steel coil;

[0059] Step 3: Slide the pressure rod 103 downward until the pressure rod 103 presses against the upper side of the steel coil;

[0060] Step 4: Use a cutting knife to cut the steel coil at a suitable length;

[0061] Step 5: operate the longitudinal slide bar 301 to slide on the bottom plate 102, and move the longitudinal slide bar 301 to the same position as the target length after the steel coil is cut;

[0062] Step 6: operate the transverse slide bar 402 to slide on the longitudinal slide bar 301, and detect the cutting and forming effect of the end face of the steel coil by the sliding condition of the detection rod 502;

[0063] Step 7: If the sliding of the detection rod 502 is caused by a small burr, the moving part 501 is continuously slid until the grinding wheel 504 contacts the burr, and the burr is removed by the rotating grinding wheel 504;

[0064] Step 8: If the sliding of the detection rod 502 is caused by a large protrusion that cannot be removed by grinding, re-cut the position to ensure the cutting effect of the finished product;

[0065] Step 9: After the cutting and end surface inspection operations are completed, the steel coil is cold rolled, annealed, flattened and refined to form the steel coil into a finished cold rolled steel plate.

[0066] A cold-rolled steel plate is produced by the cold-rolled steel plate processing method.
