[0002] Metal sheets are plate-shaped components made of metal materials through processes such as rolling and casting. They have high strength, corrosion resistance, and electrical and thermal conductivity, and are widely used in construction, automobiles, aerospace and other fields.

[0003] When processing metal sheets, the raw materials are prepared first, then inspected, and their surfaces are treated. After that, they are leveled and straightened, their thickness is changed through rolling, their size is changed through cutting, and after bending and post-processing, the finished products are packaged and finally put into storage.

[0004] If the metal sheet is not fixed during the rolling and cutting process, it will cause dimensional deviations and surface damage. Therefore, a metal sheet rolling and cutting device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A metal sheet stretching and cutting device according to this utility model includes a conveying device; a stretching device is installed on one side of the conveying device; a pad is fixedly connected to the surface of the conveying device; a cover plate is fixedly connected to the top of the stretching device; a hydraulic cylinder is fixedly connected to the surface of the cover plate; a cutter head is fixedly connected to the output end of the hydraulic cylinder; a set of first sliding grooves is opened at the bottom of the cover plate; a first linear motor is installed in the middle of the first sliding groove; a first support seat is fixedly connected to the load end of the first linear motor; a second support seat is fixedly connected to the bottom of the cover plate; the second support seat and the first linear motor... Each support base is rotatably connected to a connecting rod in the middle; a set of connecting rods is rotatably connected to a fixed column in the middle; the ends of the connecting rods are rotatably connected to another first support base and a second support base; a pressure plate is fixedly connected to the bottom of the other first support base and the second support base; the pressure plate and the cover plate are mirror images of each other; by moving the first linear motor in the first slide groove, the connecting rod rotates around the second support base, causing the pressure plate to move up and down, which can press the metal plate onto the surface of the conveying device, reducing the impact force of the cutter head during cutting and preventing the metal plate from lifting, while also reducing the displacement of the metal plate due to the cutting force, and increasing the stability of the cutting dimensions.

[0007] Preferably, a distributor is fixedly connected to the top of the cover plate; an air pipe is fixedly connected to the top of the distributor; a hot air blower is installed at the end of the air pipe; a flat air nozzle is fixedly connected to the top of the cover plate; the flat air nozzle is connected to the distributor; hot air is sprayed into the cutting area through the flat air nozzle, which locally heats the metal plate, reducing edge warping or deformation after cutting, improving material plasticity, reducing the risk of cracks during cutting, and reducing the cutting resistance of the cutter head, thus extending its life.

[0008] Preferably, a set of second sliding grooves is provided on the top of the pad; a second linear motor is installed in the middle of the second sliding groove; a guide is rotatably connected to the load end of the second linear motor; by moving the second linear motor in the second sliding groove, the guide is driven to fit against the edge of the plate, reducing the offset of the metal plate and preventing the cutting head from exceeding the cutting size tolerance.

The lubricant forms an oil film on the cutter head surface, reducing the surface temperature of the cutter head, reducing the softening of the cutting edge due to high temperature, and increasing the service life of the cutter head.

[0010] Preferably, a support plate is fixedly connected to one side of the conveying device; an electric push rod is fixedly connected to one side of the support plate; a push plate is fixedly connected to the output end of the electric push rod; a sliding plate is fixedly connected to one side of the conveying device; the sliding plate is inclined; the sliding plate and the push plate are correspondingly arranged; pushing the push plate off the surface of the conveying device by the electric push rod can reduce the accumulation of metal plates that may cause the conveying device to jam, increase the stability of continuous processing, reduce manual intervention, and increase production efficiency.

[0011] Preferably, a rubber pad is fixed to one side of the pressure plate; the rubber pad is set at the bottom of the pressure plate; by setting a rubber pad at the bottom of the pressure plate, when the pressure plate is pressed down, the rubber pad can evenly distribute the pressure through elastic deformation, reduce the generation of indentations, scratches or deformation on the surface of the metal plate, and increase the surface quality of the metal plate.

[0013] 1. The metal sheet stretching and cutting equipment of this utility model uses a first linear motor to move in a first chute, causing a connecting rod to rotate around a second support base, which in turn causes the pressure plate to move up and down. This can press the metal sheet onto the surface of the conveying device, reducing the impact force of the cutter head during cutting and preventing the metal sheet from lifting. At the same time, it reduces the displacement of the metal sheet caused by the cutting force and increases the stability of the cutting dimensions.

[0014] 2. The metal sheet stretching and cutting equipment of this utility model uses a second linear motor to move within a second chute, causing a guide to fit against the edge of the sheet, reducing metal sheet offset and preventing the cutting head from exceeding the tolerance. At the same time, the guide's constraint on the edge of the metal sheet makes the cutting head more evenly stressed during cutting, reducing the occurrence of blade tilting or chipping caused by unilateral stress.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the figure, a metal sheet stretching and cutting device according to an embodiment of the present invention includes a conveying device 1; a stretching device 11 is installed on one side of the conveying device 1; a pad 12 is fixedly connected to the surface of the conveying device 1; a cover plate 13 is fixedly connected to the top of the stretching device 11; a hydraulic cylinder 14 is fixedly connected to the surface of the cover plate 13; a cutter head 15 is fixedly connected to the output end of the hydraulic cylinder 14; a set of first sliding grooves 16 are opened at the bottom of the cover plate 13; a first linear motor 17 is installed in the middle of the first sliding grooves 16; a first support seat 18 is fixedly connected to the load end of the first linear motor 17; a second support seat 110 is fixedly connected to the bottom of the cover plate 13; a connecting rod 19 is rotatably connected to the middle of the second support seat 110 and the first support seat 18; a fixed column 111 is rotatably connected to the middle of the set of connecting rods 19; another first support seat 18 and the second support seat 110 are rotatably connected to the end of the connecting rod 19; a pressure plate 112 is fixedly connected to the bottom of the other first support seat 18 and the second support seat 110. The pressure plate 112 and the cover plate 13 are mirror images of each other. During operation, one side of the metal plate is placed in the rolling device 11 and rolled into a thin sheet. After the metal plate is extruded to the required size by contacting the surface of the conveying device 1 with the pad 12, the first linear motor 17 is controlled to move its load end along with the first support seat 18, causing the connecting rod 19 to rotate around the fixed column 111. The connecting rod 19 and the second support seat 110 cooperate to move the pressure plate 112 up and down, pressing it onto the surface of the metal plate for fixation. Then, the hydraulic cylinder 14 is controlled to extend and retract, causing its output end to drive the cutter head 15 to contact the edge of the pad 12. The extension and retraction continue to cut the metal plate. The first linear motor 17 moves in the first groove 16, causing the connecting rod 19 to rotate around the second support seat 110, which in turn moves the pressure plate 112 up and down. This can press the metal plate onto the surface of the conveying device 1, reducing the impact force of the cutter head 15 during cutting and preventing the metal plate from lifting. It also reduces the displacement of the metal plate caused by the cutting force, increasing the stability of the cutting size.

[0026] like Figure 1 and Figure 4 As shown, a distributor 2 is fixedly connected to the top of the cover plate 13; an air pipe 21 is fixedly connected to the top of the distributor 2; a hot air blower is installed at the end of the air pipe 21; a flat air nozzle 22 is fixedly connected to the top of the cover plate 13; the flat air nozzle 22 is connected to the distributor 2; during operation, the hot air blower delivers hot air to the distributor 2 through the air pipe 21; then blows it out through the flat air nozzle 22, spraying hot air into the cutting area through the flat air nozzle 22, which locally heats the metal plate, reducing warping or deformation after cutting, improving material plasticity, reducing the risk of cracks during cutting, and reducing the cutting resistance of the cutter head 15, thus extending its life.

[0027] like Figure 1 and Figure 6As shown, a set of second sliding grooves 3 are provided on the top of the pad 12; a second linear motor 31 is installed in the middle of the second sliding groove 3; a guide 32 is rotatably connected to the load end of the second linear motor 31; during operation, the second linear motor 31 is controlled to move its load end with the guide 32 to contact the edge of the metal plate. The movement of the second linear motor 31 in the second sliding groove 3 drives the guide 32 to fit against the edge of the plate, reducing the offset of the metal plate and preventing the cutting head 15 from exceeding the cutting size tolerance. At the same time, the constraint of the guide 32 on the edge of the metal plate makes the cutting head 15 more evenly stressed when cutting, reducing the occurrence of blade tilting or chipping caused by unilateral stress.

[0028] like Figure 1 and Figure 5 As shown, a set of bases 4 are fixedly connected to the top of the cutter head 15; an oil bladder 41 is installed on the top of the base 4; a set of oil nozzles 42 are installed on the surface of the cover plate 13; a one-way valve is provided inside the oil nozzles 42; the oil nozzles 42 are connected to the oil bladder 41; a hose 43 is fixedly connected to one side of the base 4; an oil mist nozzle 44 is fixedly connected to the end of the hose 43; during operation, lubricant is injected into the oil nozzles 42, and when the cutter head 15 is lifted after cutting, the cutter head 15 and the cover plate 13 squeeze the oil bladder 41 to make... The lubricant inside the oil bladder 41 is sprayed onto the surface of the cutter head 15 through the oil mist nozzle 44 via the hose 43. Automatic spraying can be achieved by squeezing the oil bladder 41 when the cutter head 15 rises, thus spraying the lubricant onto the surface of the cutter head 15. The lubricant forms an oil film on the surface of the cutter head 15, which reduces the surface temperature of the cutter head 15, reduces the softening of the cutting edge caused by high temperature, and increases the service life of the cutter head 15. At the same time, the lubricant reduces the friction between the metal plate and the cutter head 15, increases the smoothness of the cut surface, and reduces the generation of burrs.

[0029] like Figure 1 As shown, a support plate 5 is fixedly connected to one side of the conveying device 1; an electric push rod 51 is fixedly connected to one side of the support plate 5; a push plate 52 is fixedly connected to the output end of the electric push rod 51; a sliding plate 53 is fixedly connected to one side of the conveying device 1; the sliding plate 53 is inclined; the sliding plate 53 and the push plate 52 are correspondingly arranged; during operation, the electric push rod 51 is controlled to extend and retract, so that its output end moves with the push plate 52; the cut metal plate is pushed to the sliding plate 53, slides down along the inclined edge of the sliding plate 53 for collection, and the push plate 52 is pushed off the surface of the conveying device 1 by the electric push rod 51 to push the metal plate off the surface of the conveying device 1, which can reduce the accumulation of metal plates and prevent the conveying device 1 from jamming, increase the stability of continuous processing, reduce manual intervention, and increase production efficiency.

[0030] like Figure 2As shown, a rubber pad 6 is fixed to one side of the pressure plate 112; the rubber pad 6 is set at the bottom of the pressure plate 112; during operation, when the pressure plate 112 contacts the metal plate for fixing, the rubber pad 6 is squeezed between the metal plate and the pressure plate 112 to reduce the direct contact between the two, and at the same time buffer the impact force of the pressure plate 112 contacting the metal plate. By setting the rubber pad 6 at the bottom of the pressure plate 112, when the pressure plate 112 is pressed down, the rubber pad 6 can evenly distribute the pressure through elastic deformation, reduce the generation of indentations, scratches or deformation on the surface of the metal plate, and increase the surface quality of the metal plate.

[0031] Working principle: A metal sheet is placed in the extrusion device 11 and extruded into a thin sheet. After the sheet is extruded to the required size by the contact plate 12 with the conveying device 1, the first linear motor 17 is controlled to move the first support 18 along its load end, causing the connecting rod 19 to rotate around the fixed column 111. The connecting rod 19 and the second support 110 cooperate to move the pressure plate 112 up and down, pressing it against the surface of the metal sheet for fixation. Then, the hydraulic cylinder 14 is controlled to extend and retract, causing its output end to drive the cutter head 15 to contact the edge of the pad 12. The extension and retraction continue to cut the metal sheet. The hot air blower delivers hot air to the distributor 2 through the air pipe 21; then, it is blown through the flat nozzle 22. The second linear motor 31 is controlled to move its load end along with the guide 32 to contact the edge of the metal plate and inject lubricant into the oil nozzle 42. When the cutter head 15 is lifted after cutting, the cutter head 15 and the cover plate 13 squeeze the oil bladder 41, causing the lubricant inside the oil bladder 41 to be sprayed from the oil mist nozzle 44 through the hose 43 onto the surface of the cutter head 15. The electric push rod 51 is controlled to extend and retract, so that its output end moves along with the push plate 52. The cut metal plate is pushed to the slide plate 53 and slides down along the inclined edge of the slide plate 53 for collection. When the pressure plate 112 contacts the metal plate for fixing, the rubber pad 6 is squeezed between the metal plate and the pressure plate 112 to reduce the direct contact between the two and at the same time buffer the impact force of the pressure plate 112 contacting the metal plate.
