Description

Technical Field

[0001] The invention relates to the technical field of steel processing, in particular to a grinding device for cold-rolled steel processing with an anti-deformation function. Background Art

[0002] In the modern steel industry, cold-rolled steel processing is an important part of improving the quality and performance of steel, and grinding technology, as a key process, plays a decisive role in improving the surface quality of steel. Whether it is construction, automobile manufacturing, home appliances or precision machinery, many industries have strict requirements on the surface quality of cold-rolled steel plates, such as surface flatness, smoothness and micro-texture, etc. These requirements are directly related to the product's appearance, corrosion resistance, coating and plating performance, and the convenience of subsequent processing.

[0003] However, traditional cold-rolled steel grinding equipment faces many challenges in practical applications. First, during the grinding process, due to the inevitable unevenness on the surface of the rolled steel, existing grinding equipment often finds it difficult to automatically adjust the grinding angle according to the surface conditions. When the grinding angle is fixed, the contact area and pressure distribution between the grinding head and the rolled steel are uneven on the raised parts of the rolled steel surface, and the local pressure is too high, which can easily cause the rolled steel to become concave and deformed; while in the concave parts, insufficient or uneven grinding may occur due to poor contact, further affecting the consistency of surface quality.

[0004] Secondly, if the large amount of heat generated during the grinding process cannot be dissipated in time, the local temperature of the rolled steel will rise sharply. When the rolled steel is heated unevenly, thermal stress will be generated inside. This thermal stress and the grinding force will significantly increase the risk of deformation of the rolled steel. Especially for some thin cold-rolled steel plates with high precision requirements, even a slight deformation may make it unable to meet the requirements of subsequent processing technology, resulting in product scrapping and increased production costs.

[0005] In addition, in actual production, the height and width of rolled steel are not completely fixed, and there are certain dimensional tolerances and dynamic changes in the production process. Traditional grinding equipment lacks the ability to adaptively adjust the height and width of rolled steel. When the size of rolled steel does not match the preset parameters of the equipment, it is easy to cause insufficient or excessive grinding, which not only affects the surface quality, but also may damage the edge of the rolled steel and reduce the yield rate. Summary of the invention

[0006] The purpose of the present invention is to provide a grinding device for cold-rolled steel processing with an anti-deformation function to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions: The grinding equipment for cold-rolled steel processing with anti-deformation function comprises a workbench, a shaping and adjusting distance unit, a grinding unit, a cooling unit and a controller, wherein the workbench is placed on a horizontal basis, the shaping and adjusting distance unit is fixedly mounted on the workbench, the shaping and adjusting distance unit has a function of changing the grinding height of the grinding unit, the shaping and adjusting distance unit is electrically connected to the grinding unit, the grinding unit is fixedly mounted on the workbench, the cooling unit is fixedly connected to the shaping and adjusting distance unit, the grinding unit is fixedly connected to the cooling unit, the grinding unit has a function of changing the spraying angle of the cooling unit, and the controller is fixedly connected to the workbench; The workbench is used to install and fix the shaping and pitch-adjusting unit, the grinding unit, the cooling unit and the controller. The controller is used to control the opening and closing of the shaping and pitch-adjusting unit, the grinding unit and the cooling unit. The shaping and pitch-adjusting unit is used to adapt to the transportation and shaping of rolled steel of different widths and heights. The grinding unit is used to grind the rolled steel. The cooling unit is used to cool the rolled steel during the grinding process. When the rolled steel is conveyed to the shaping and pitch-adjusting unit, the rolled steel is corrected by the shaping and pitch-adjusting unit and the height of the grinding unit is adjusted according to the thickness of the rolled steel. The rolled steel is evenly ground by the grinding unit to avoid deformation caused by uneven local force at the concave and convex parts of the rolled steel surface due to grinding pressure. At the same time, the cooling unit is used to cool the grinding part to avoid deformation caused by excessive grinding temperature. The shaping and pitch-adjusting unit comprises a driving motor, a driving wheel, a driven wheel, a conveyor belt, a conveyor roller, an electromagnet, a shaping frame, a light source, a photoresistor group, a guide rod and a conductive ring.

A cavity is opened at one end of the workbench close to the conveying roller, and the guide rod is fixedly installed in the cavity of the workbench parallel to the conveying roller. The conductive ring is evenly fixedly installed on the guide rod, and the shaping frame is slidably connected to the guide rod. A conductive block is arranged at the contact end of the shaping frame and the guide rod, and the conductive block of the shaping frame is electrically connected to the grinding unit.

[0008] When the rolled steel is transported to the conveyor roller, the controller controls the drive motor to start, thereby driving the driving wheel to rotate, and the driven wheel is driven to rotate under the transmission action of the conveyor belt, so that the conveyor roller rotates and the rolled steel is transported forward. At this time, the controller inputs current into the electromagnet, so that the electromagnet and the shaping frame made of magnet material have the same polarity, thereby pushing the shaping frame to approach each other, shaping the rolled steel with incorrect posture, avoiding uneven grinding caused by incorrect posture of the rolled steel, and at the same time, the conductive block on the shaping frame moves on the guide rod and contacts with the conductive ring, so that the corresponding line The coil receives current and starts working until the thin-film pressure sensor on the shaping frame detects that the pressure is at the set value, and then feeds back a signal to the controller, so that the controller stops supplying current to the electromagnet. After the shaping is completed, the rolled steel blocks the light source at the rectangular through slot of the shaping frame, so that the resistance value of the photoresistor on the photoresistor group changes. According to the number of photoresistors blocked by rolled steel of different thicknesses, the corresponding resistance value is presented. When the current of the controller passes through the entire photoresistor group from bottom to top, the resistance value of the photoresistor group increases, so that the current supplied to the memory spring 1 gradually decreases, thereby gradually restoring the length.

[0009] Furthermore, the grinding unit includes a fixed box, a memory spring 1, a wire harness box, a lifting plate, a grinding motor, a grinding cylinder, a memory spring 2, a telescopic rod, a straight rod, a coil and a rotating shaft. The fixed box is fixedly mounted on the upper surface of the workbench, the wire harness box is fixedly mounted on the inner surface of the fixed box near one end of the workbench, there are two lifting plates, the lifting plate is connected to the wire harness box through a memory spring 1, the memory spring 1 is initially in an energized and contracted state, the memory spring 1 is electrically connected to the photoresistor group, the fixed end of the grinding motor is fixedly mounted on the upper surface of the lifting plate, the output end of the grinding motor is fixedly connected to one end of the rotating shaft, and the rotating The other end of the shaft is fixedly connected to the lifting plate through a bent rod, one end of the memory spring is fixedly connected to the inner surface of the grinding cylinder, and the other end is fixedly connected to the outer surface of the rotating shaft, the telescopic end of the telescopic rod is fixedly connected to the inner surface of the grinding cylinder, the fixed end of the telescopic rod is fixedly connected to the outer surface of the rotating shaft, an iron ring is provided at the telescopic end of the telescopic rod away from the grinding cylinder, the telescopic end of the telescopic rod is slidably connected to the straight rod, a coil is evenly wound on the surface of the straight rod, the straight rod is fixedly installed inside the fixed end of the telescopic rod, the coil is electrically connected to the conductive block of the shaping frame, the lifting plate is fixedly connected to the cooling unit, and the coil is electrically connected to the memory spring.

[0010] When the current received by memory spring 1 decreases, memory spring 1 gradually stretches and recovers, thereby lifting the lifting plate upward, driving the grinding motor and the grinding cylinder to synchronously lift upward until the grinding cylinder contacts the surface of the rolled steel, thereby achieving the grinding of rolled steel of different thicknesses. When the rolled steel passes under the grinding cylinder, the controller controls the grinding motor to start, thereby driving the grinding cylinder to rotate under the transmission action of the rotating shaft and memory spring 2, and grinding the surface of the rolled steel. When there are concave and convex parts in multiple areas on the surface of the rolled steel, in order to avoid uneven grinding pressure on the rolled steel due to the fixed contact distance between the grinding cylinder and the rolled steel surface, resulting in excessive grinding pressure on the convex part causing deformation of the rolled steel and insufficient grinding pressure on the concave part causing the unpolished part, in the area of ​​the convex part of the rolled steel, the grinding cylinder there is squeezed, from The second memory spring is compressed to shrink the grinding radius, and the pressure is roughly adjusted. At the same time, the iron ring of the telescopic part of the telescopic rod moves toward the center. At this time, the effective number of turns of the coil increases, which reduces the current delivered to the second memory spring, thereby contracting the second memory spring for fine adjustment, ensuring that constant pressure grinding is performed when the grinding cylinder contacts the raised part, avoiding deformation of the rolled steel due to excessive pressure. In the area of ​​the rolled steel recessed part, when the pressure on the grinding cylinder there is reduced, the second memory spring extends under the action of its own restoring force. At this time, the effective number of turns of the iron ring of the telescopic part of the telescopic rod in contact with the coil on the straight rod is reduced, and the current increases, thereby pushing the second memory spring to receive the current and extend to a certain length for the second time, so that the grinding cylinder and the rolled steel recessed part maintain a certain pressure, thereby ensuring the uniformity of the grinding of the rolled steel surface in the recessed part.

[0011] Furthermore, the cooling unit includes a support rod, a water pipe, a rotating drum and a pull rope, one end of the support rod is fixedly mounted on the upper surface of the electromagnet, both ends of the water pipe are fixedly connected to the support rod, the water pipe is conductively connected to an external water pump, the rotating drum is coaxially placed with the water pipe, both ends of the rotating drum are connected to the water pipe through a torsion spring, a lifting ear is provided on the outer surface of the rotating drum, one end of the pull rope is fixedly connected to the lifting ear on the rotating drum, and the other end passes through the wiring box and is fixedly connected to the lifting plate, and the rotating drum is conductively connected to the water pipe through a pipeline.

[0012] When encountering thick rolled steel, the memory spring pushes the lifting plate up and the pull rope is released. The torsion spring's own restoring force drives the rotating drum to rotate clockwise, causing the nozzle on the rotating drum to flip upward. At this time, the controller controls the water pump to deliver cold water to the water pipe, thereby spraying cold water on the contact area between the grinding drum and the rolled steel to avoid deformation of the rolled steel caused by high temperature during the grinding process.

[0013] Furthermore, the coils on the grinding cylinder with the same axis as the plurality of conductive rings are independently controlled.

[0014] In order to avoid the situation where the narrow rolled steel is not in contact with the grinding cylinder and the corresponding pressure control is not performed, the memory spring 2 and the coil may respond during the grinding process, which may lead to misjudgment of the area as a recessed area and cause wear on the workbench or other structures.

[0015] Furthermore, the outer surfaces of the plurality of grinding cylinders are completely covered by a flexible grinding plate with a roughened surface.

[0016] During the grinding process of rolled steel, no matter the rolled steel surface is flat or has certain unevenness, the flexible grinding plate can be deformed according to the shape of the rolled steel surface, so that each grinding cylinder can participate in the grinding process, ensuring that the grinding cylinder always maintains good contact with the rolled steel surface, and ensuring that all parts of the rolled steel surface can be evenly ground.

[0017] Furthermore, a nozzle is provided on the rotating drum, and an initial angle of the nozzle on the rotating drum with the horizontal axis is 135 degrees, and the direction is horizontally downward.

[0018] In order to allow cold water to be sprayed onto the surface of the rolled steel at a specific angle, when the grinding equipment is adjusted as the height of the rolled steel changes, this angle can ensure that the coolant covers the grinding area while reducing the splashing and loss of the coolant, so that the coolant can better adhere to the surface of the rolled steel, absorb heat and take away heat, and prevent high temperature deformation caused by grinding.

[0019] Furthermore, the coil on the straight rod is composed of two parts, the end of the lower coil away from the rotating shaft is the current receiving end, and the end of the upper coil close to the grinding cylinder is the current receiving end. The coils on the same axis of the two adjacent grinding cylinders are electrically connected by a branch circuit at the current receiving end, and the current direction is transmitted from the two ends of the grinding cylinder to the center.

[0020] In order to achieve the corresponding expansion and contraction of the coil and the memory spring 2 during the grinding process of the grinding cylinder on the concave and convex parts of the rolled steel surface, so as to avoid the deformation of the rolled steel surface caused by excessive grinding pressure or uneven grinding caused by insufficient grinding pressure. At the same time, the coil current is transmitted from both ends to the center to avoid the situation where the grinding cylinders at both ends that are not grinding are damaged by misoperation and cause damage to the equipment.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention pushes the shaping frames closer to each other through electromagnets to shape the rolled steel with incorrect posture, thereby avoiding uneven grinding caused by incorrect rolled steel posture. At the same time, the shaping frame contacts with the conductive ring and responds to the corresponding coil receiving current to start working, preparing for grinding the concave and convex areas of the rolled steel. The rolled steel blocks the light source, so that the resistance value of the photoresistor on the photoresistor group presents a corresponding resistance value according to the number of rolled steels of different thicknesses blocking the photoresistor. When the current passes through the entire photoresistor group from bottom to top, the current delivered to the memory spring 1 is reduced to restore its length.

[0022] 2. The present invention gradually stretches and recovers the memory spring 1, thereby lifting the lifting plate upward and making the grinding cylinder contact with the surface of the rolled steel, thereby realizing the grinding of rolled steel of different thicknesses. In the area of ​​the raised part of the rolled steel, the grinding cylinder there is squeezed, thereby compressing the memory spring 2 to shrink the grinding radius, and the iron ring of the telescopic part of the telescopic rod moves toward the center while the pressure is roughly adjusted. At this time, the effective number of turns of the coil increases, and the current delivered to the memory spring 2 is reduced, so that the memory spring 2 is contracted to perform fine pressure adjustment, ensuring that the grinding cylinder is ground at a constant pressure when in contact with the raised part, and avoiding deformation of the rolled steel due to excessive pressure. In the area of ​​the depressed part of the rolled steel, when the pressure on the grinding cylinder there is reduced, the memory spring 2 is stretched under the action of its own restoring force, and the effective number of turns of the iron ring of the telescopic part of the telescopic rod in contact with the coil on the straight rod is reduced, and the current is increased, thereby pushing the memory spring 2 to receive the current and stretch to a certain length for the second time, so that the grinding cylinder and the depressed part of the rolled steel maintain a certain pressure, thereby ensuring the uniformity of the grinding of the surface of the rolled steel at the depressed part.

[0023] 3. When encountering thick rolled steel, the present invention releases the pull rope while the memory spring pushes the lifting plate upward, and the torsion spring's own restoring force drives the rotating drum to rotate clockwise, so that the nozzle on the rotating drum flips upward, and cold water is sprayed on the contact part between the grinding drum and the rolled steel to cool it down, thereby avoiding deformation of the rolled steel caused by high temperature during the grinding process.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The controller 5 is used for controlling the opening and closing of the shaping and pitch-adjusting unit 2, the grinding unit 3 and the cooling unit 4. The shaping and pitch-adjusting unit 2 is used for adapting to the conveying and shaping of rolled steel of different widths and heights. The grinding unit 3 is used for grinding the rolled steel. The cooling unit 4 is used for cooling the rolled steel during the grinding process. When the rolled steel is conveyed to the shaping and pitch-adjusting unit 2, the rolled steel is corrected by the shaping and pitch-adjusting unit 2 and the height of the grinding unit 3 is adjusted according to the thickness of the rolled steel. The rolled steel is evenly ground by the grinding unit 3 to avoid deformation caused by uneven local force at the concave and convex parts of the rolled steel surface due to the grinding pressure. At the same time, the cooling unit 4 is used to cool the grinding part to avoid deformation caused by excessive grinding temperature. The shaping and pitch-adjusting unit 2 comprises a driving motor 21, a driving wheel 22, a driven wheel 23, a conveyor belt 24, a conveyor roller 25, an electromagnet 26, a shaping frame 27, a light source 28, a photoresistor group 29, a guide rod 210 and a conductive ring 211. The fixed end of the driving motor 21 is fixedly mounted on the workbench 1, the output end of the driving motor 21 is fixedly connected to the driving wheel 22, the driving wheel 22 is connected to the driven wheel 23 through the conveyor belt 24, the driven wheel 23 is fixedly mounted on the conveyor roller 25, the two ends of the conveyor roller 25 are rotatably mounted on the two ends of the inner side of the workbench 1, the electromagnet 26 is fixedly mounted on the surface of the workbench 1 away from the horizontal foundation, the shaping frame 27 is slidably mounted on the upper surface of the workbench 1, the shaping frame 27 is made of a magnet, and the shaping frame 27 is close to the conveyor roller 25. A rectangular through groove is opened at the end, and a thin film pressure sensor is arranged in the rectangular through groove. The light source 28 is fixedly installed on the inner wall of one side of the rectangular notch of the shaping frame 27. In the vertical direction, the photoresistor group 29 is evenly fixedly installed on the inner wall opposite to the light source 28. The end of the photoresistor group 29 close to the horizontal foundation is a current receiving end. The photoresistor group 29 is electrically connected to the grinding unit 3. A cavity is opened at the end of the workbench 1 close to the conveying roller 25. The guide rod 210 is fixedly installed in the cavity of the workbench 1 parallel to the conveying roller 25. The conductive ring 211 is evenly fixedly installed on the guide rod 210. The shaping frame 27 is slidably connected to the guide rod 210. The contact end of the shaping frame 27 and the guide rod 210 is provided with a conductive block, and the conductive block of the shaping frame 27 is electrically connected to the grinding unit 3.

[0028] When the rolled steel is transported to the conveyor roller 25, the controller 5 controls the drive motor 21 to start, thereby driving the driving wheel 22 to rotate, and driving the driven wheel 23 to rotate under the transmission action of the conveyor belt 24, so that the conveyor roller 25 rotates to transport the rolled steel forward. At this time, the controller 5 passes current into the electromagnet 26, so that the electromagnet 26 and the shaping frame 27 made of magnetic material have the same polarity, thereby pushing the shaping frame 27 to approach each other, shaping the rolled steel with incorrect posture, avoiding uneven grinding caused by incorrect posture of the rolled steel, and at the same time, the conductive block on the shaping frame 27 moves on the guide rod 210 and contacts with the conductive ring 211, so that The corresponding coil 310 receives current and starts working until the sheet pressure sensor on the shaping frame 27 detects that the pressure is at the set value, and then feeds back a signal to the controller 5, so that the controller 5 stops supplying current to the electromagnet 26. After the shaping is completed, the rolled steel blocks the light source 28 at the rectangular through groove of the shaping frame 27, so that the resistance value of the photoresistor on the photoresistor group 29 changes. According to the number of photoresistors blocked by rolled steel of different thicknesses, the corresponding resistance value is presented. When the current of the controller 5 passes through the entire photoresistor group 29 from bottom to top, the resistance value of the photoresistor group 29 increases, so that the current supplied to the memory spring 32 gradually decreases, thereby gradually restoring the length.

[0029] like Figure 2 , 6 As shown in , 7 and 10, the grinding unit 3 includes a fixed box 31, a memory spring 1 32, a wire harness box 33, a lifting plate 34, a grinding motor 35, a grinding cylinder 36, a memory spring 2 37, a telescopic rod 38, a straight rod 39, a coil 310 and a rotating shaft 311. The fixed box 31 is fixedly mounted on the upper surface of the workbench 1, the wire harness box 33 is fixedly mounted on the inner surface of one end of the fixed box 31 close to the workbench 1, there are two lifting plates 34, the lifting plates 34 are connected to the wire harness box 33 through the memory spring 1 32, the memory spring 1 32 is initially in an energized contracted state, the memory spring 1 32 is electrically connected to the photoresistor group 29, the fixed end of the grinding motor 35 is fixedly mounted on the upper surface of the lifting plate 34, and the output end of the grinding motor 35 is fixed to one end of the rotating shaft 311 The other end of the rotating shaft 311 is fixedly connected to the lifting plate 34 through a bent rod, one end of the memory spring 2 37 is fixedly connected to the inner surface of the grinding cylinder 36, and the other end is fixedly connected to the outer surface of the rotating shaft 311, the telescopic end of the telescopic rod 38 is fixedly connected to the inner surface of the grinding cylinder 36, the fixed end of the telescopic rod 38 is fixedly connected to the outer surface of the rotating shaft 311, an iron ring is provided at one end of the telescopic end of the telescopic rod 38 away from the grinding cylinder 36, the telescopic end of the telescopic rod 38 is slidably connected to the straight rod 39, the surface of the straight rod 39 is evenly wound with a coil 310, the straight rod 39 is fixedly installed inside the fixed end of the telescopic rod 38, the coil 310 is electrically connected to the conductive block of the shaping frame 27, the lifting plate 34 is fixedly connected to the cooling unit 4, and the coil 310 is electrically connected to the memory spring 2 37.

[0030] When the current received by the memory spring 32 decreases, the memory spring 32 gradually stretches and recovers, thereby lifting the lifting plate 34 upward, driving the grinding motor 35 and the grinding cylinder 36 to synchronously lift upward until the grinding cylinder 36 contacts the surface of the rolled steel, thereby achieving the grinding of rolled steel of different thicknesses. When the rolled steel passes under the grinding cylinder 36, the controller 5 controls the grinding motor 35 to start, thereby driving the grinding cylinder 36 to rotate under the transmission action of the rotating shaft 311 and the memory spring 2 37 to grind the surface of the rolled steel. When there are concave and convex parts in multiple areas on the surface of the rolled steel, in order to avoid uneven grinding pressure on the rolled steel due to the fixed contact distance between the grinding cylinder 36 and the rolled steel surface, resulting in excessive grinding pressure on the convex part causing deformation of the rolled steel and insufficient grinding pressure on the concave part causing the unpolished part, in the area of ​​the convex part of the rolled steel, the grinding cylinder 36 at that place is squeezed, from The compression memory spring 2 37 shrinks the grinding radius, and the pressure is roughly adjusted. At the same time, the iron ring of the telescopic part of the telescopic rod 38 moves toward the center. At this time, the effective number of turns of the coil 310 increases, and the current delivered to the memory spring 2 37 is reduced, so that the memory spring 2 37 is contracted for fine adjustment, ensuring that the grinding cylinder 36 is ground at a constant pressure when in contact with the raised part, avoiding deformation of the rolled steel due to excessive pressure. In the area of ​​the rolled steel recessed part, when the pressure on the grinding cylinder 36 there is reduced, the memory spring 2 37 extends under the action of its own restoring force. At this time, the effective number of turns of the iron ring of the telescopic part of the telescopic rod 38 in contact with the coil 310 on the straight rod 39 is reduced, and the current is increased, thereby pushing the memory spring 2 37 to receive the current and extend it twice to a certain length, so that the grinding cylinder 36 and the rolled steel recessed part maintain a certain pressure, thereby ensuring the uniformity of the grinding of the rolled steel surface in the recessed part.

[0031] like Figure 2 , 3 As shown in Figure 4, the cooling unit 4 includes a support rod 41, a water pipe 42, a rotating drum 43 and a pull rope 44.

One end of the pull rope 44 is fixedly connected to the lifting ear on the rotating drum 43, and the other end passes through the harness box 33 and is fixedly connected to the lifting plate 34. The rotating drum 43 and the water pipe 42 are conductively connected through a pipeline.

[0032] When encountering thick rolled steel, while the memory spring 32 pushes the lifting plate 34 to rise, the pull rope 44 is loosened, and the rotating drum 43 is driven to rotate clockwise under the action of the torsion spring's own restoring force, so that the nozzle on the rotating drum 43 flips upward. At this time, the controller 5 controls the water pump to transport cold water to the water pipe 42, so as to spray cold water on the contact part between the grinding drum 36 and the rolled steel, so as to avoid deformation of the rolled steel caused by high temperature during the grinding process.

[0033] like Figure 4 As shown, the plurality of conductive rings 211 and the coil 310 on the grinding cylinder 36 on the same axis are independently controlled.

[0034] In order to avoid the narrow rolled steel not in contact with the grinding cylinder 36 without corresponding pressure control, the memory spring 2 37 and the coil 310 can be prevented from responding during the grinding process, thereby misjudging the area as a recessed area and causing wear on the workbench 1 or other structures.

[0035] like Figure 1 As shown, the outer surfaces of the plurality of grinding cylinders 36 are completely covered by a flexible grinding plate with a roughened surface.

[0036] During the process of grinding rolled steel, no matter whether the rolled steel surface is flat or has certain unevenness, the flexible grinding plate can be deformed according to the shape of the rolled steel surface, so that each grinding cylinder 36 can participate in the grinding process, ensuring that the grinding cylinder 36 always maintains good contact with the rolled steel surface, and ensuring that all parts of the rolled steel surface can be evenly ground.

[0037] like Figure 5 As shown, a nozzle is provided on the rotating drum 43, and the nozzle on the rotating drum 43 initially forms an angle of 135 degrees with the horizontal axis and is directed horizontally downward.

[0038] In order to allow cold water to be sprayed onto the surface of the rolled steel at a specific angle, when the grinding equipment is adjusted as the height of the rolled steel changes, this angle can ensure that the coolant covers the grinding area while reducing the splashing and loss of the coolant, so that the coolant can better adhere to the surface of the rolled steel, absorb heat and take away heat, and prevent high temperature deformation caused by grinding.

[0039] like Fig.10 As shown, the coil 310 on the straight rod 39 consists of two parts, the end of the lower coil 310 away from the rotating shaft 311 is the current receiving end, and the end of the upper coil 310 close to the grinding cylinder 36 is the current receiving end. The coils 310 on the same axis of two adjacent grinding cylinders 36 are electrically connected at the branch circuit set at the current receiving end, and the current direction is transmitted from the two ends of the grinding cylinder 36 to the center.

[0040] In order to achieve the corresponding expansion and contraction of the coil 310 and the memory spring 2 37 during the grinding process of the concave and convex parts of the rolled steel surface by the grinding cylinder 36, so as to avoid the deformation of the rolled steel surface caused by excessive grinding pressure or uneven grinding caused by insufficient grinding pressure. At the same time, the way in which the current of the coil 310 is transmitted from both ends to the center avoids the situation in which the grinding cylinder 36 that has not been polished at both ends is damaged by misoperation of the grinding cylinder 36 and causes damage to the equipment.

[0041] Working principle of the present invention: When the rolled steel is transported to the conveyor roller 25, the controller 5 controls the drive motor 21 to start, thereby driving the driving wheel 22 to rotate, and driving the driven wheel 23 to rotate under the transmission action of the conveyor belt 24, so that the conveyor roller 25 rotates to transport the rolled steel forward. At this time, the controller 5 passes current into the electromagnet 26, so that the electromagnet 26 and the shaping frame 27 made of magnetic material have the same polarity, thereby pushing the shaping frame 27 to approach each other, shaping the rolled steel with incorrect posture, avoiding uneven grinding caused by incorrect posture of the rolled steel, and at the same time, the conductive block on the shaping frame 27 moves on the guide rod 210 and contacts with the conductive ring 211, so that The corresponding coil 310 receives current and starts working until the sheet pressure sensor on the shaping frame 27 detects that the pressure is at the set value, and then feeds back a signal to the controller 5, so that the controller 5 stops supplying current to the electromagnet 26. After the shaping is completed, the rolled steel blocks the light source 28 at the rectangular through groove of the shaping frame 27, so that the resistance value of the photoresistor on the photoresistor group 29 changes. According to the number of photoresistors blocked by rolled steel of different thicknesses, the corresponding resistance value is presented. When the current of the controller 5 passes through the entire photoresistor group 29 from bottom to top, the resistance value of the photoresistor group 29 increases, so that the current supplied to the memory spring 32 gradually decreases, thereby gradually restoring the length.

[0042] When the current received by the memory spring 32 decreases, the memory spring 32 gradually stretches and recovers, thereby lifting the lifting plate 34 upward, driving the grinding motor 35 and the grinding cylinder 36 to synchronously lift upward until the grinding cylinder 36 contacts the surface of the rolled steel, thereby achieving the grinding of rolled steel of different thicknesses. When the rolled steel passes under the grinding cylinder 36, the controller 5 controls the grinding motor 35 to start, thereby driving the grinding cylinder 36 to rotate under the transmission action of the rotating shaft 311 and the memory spring 2 37 to grind the surface of the rolled steel. When there are concave and convex parts in multiple areas on the surface of the rolled steel, in order to avoid uneven grinding pressure on the rolled steel due to the fixed contact distance between the grinding cylinder 36 and the rolled steel surface, resulting in excessive grinding pressure on the convex part causing deformation of the rolled steel and insufficient grinding pressure on the concave part causing the unpolished part, in the area of ​​the convex part of the rolled steel, the grinding cylinder 36 at that place is squeezed, from The compression memory spring 2 37 shrinks the grinding radius, and the pressure is roughly adjusted. At the same time, the iron ring of the telescopic part of the telescopic rod 38 moves toward the center. At this time, the effective number of turns of the coil 310 increases, and the current delivered to the memory spring 2 37 is reduced, so that the memory spring 2 37 is contracted for fine adjustment, ensuring that the grinding cylinder 36 is ground at a constant pressure when in contact with the raised part, avoiding deformation of the rolled steel due to excessive pressure. In the area of ​​the rolled steel recessed part, when the pressure on the grinding cylinder 36 there is reduced, the memory spring 2 37 extends under the action of its own restoring force. At this time, the effective number of turns of the iron ring of the telescopic part of the telescopic rod 38 in contact with the coil 310 on the straight rod 39 is reduced, and the current is increased, thereby pushing the memory spring 2 37 to receive the current and extend it twice to a certain length, so that the grinding cylinder 36 and the rolled steel recessed part maintain a certain pressure, thereby ensuring the uniformity of the grinding of the rolled steel surface in the recessed part.

[0043] When encountering thick rolled steel, while the memory spring 32 pushes the lifting plate 34 to rise, the pull rope 44 is loosened, and the rotating drum 43 is driven to rotate clockwise under the action of the torsion spring's own restoring force, so that the nozzle on the rotating drum 43 flips upward. At this time, the controller 5 controls the water pump to transport cold water to the water pipe 42, so as to spray cold water on the contact part between the grinding drum 36 and the rolled steel, so as to avoid deformation of the rolled steel caused by high temperature during the grinding process.
