Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a metal plate forming press. Background Art

[0002] The press applies pressure to the metal plate through the stamping die, causing it to separate or deform to achieve the desired shape and size. The stamping die repeatedly contacts the sheet metal during operation. In order to reduce the wear of the stamping die and the sheet metal, the stamping blade surface usually needs to be kept lubricated to avoid the workpieces from sticking and being difficult to separate. Due to the high frequency of contact between the stamping die and the sheet metal, the stamping oil on the stamping die is consumed quickly, and the stamping die needs to be frequently coated with stamping oil. Each time the stamping die is coated with stamping oil, the equipment needs to be shut down, resulting in frequent shutdowns of the equipment, affecting the service life of the equipment and reducing work efficiency.

[0080] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0081] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0083] like Figures 1 to 17 As shown, the present application proposes a metal sheet forming press machine, including a workbench 100, a punching device 111 and a sheet material body 130, a support frame 110 is fixed on the workbench 100, the punching device 111 is fixed on the support frame 110, a conveying device 120 is fixed on the side of the workbench 100, the conveying device 120 is used to convey the sheet material body 130, so that the sheet material body 130 completes the punching operation, and also includes a punching assembly 200, the punching assembly 200 is located above the sheet material body 130;

[0084] The punching assembly 200 includes a punching die 210, an oiling unit 220 and a driving unit 230;

[0085] The punching die 210 is a cylinder with a hollow interior and an open end, and the end away from the open end is fixed to the output end of the punching device 111. The punching die 210 is used to punch out a circular metal sheet. The punching device 111 is an oil cylinder. The punching device 111 drives the punching die 210 to rise and fall to punch the sheet body 130.

[0086] The driving part 230 includes a driving motor 2301, a telescopic cylinder 2302 and a fixing block 231. The driving part 230 is used to drive the oiling part 220 to perform lifting, rotation and telescopic movements;

[0087] The driving motor 2301 is fixed to the top of the punching die 210, and the telescopic cylinder 2302 is fixed to the driving end of the driving motor 2301. The driving motor 2301 is used to drive the telescopic cylinder 2302 to rotate, and the telescopic cylinder 2302 is used to drive the fixed block 231 to rise and fall.

[0088] The fixed block 231 is a cylinder and a cylinder 232 is fixed on its side. The fixed block 231 coincides with the axis of the punching die 210. A vent pipe 243 is fixed to the bottom of the fixed block 231. One end of the vent pipe 243 is connected to an air pump, and the air pump is fixed on the fixed block 231.

[0089] The oiling part 220 includes an oil storage box 221, which is an arc-shaped box with a hollow interior and is filled with stamping oil. The stamping oil is used to reduce the friction and wear of the stamping die 210. The free end of the cylinder 232 is fixed to the oil storage box 221, and the oil storage box 221 is driven to move by the extension of the cylinder 232. An oiling seat 2211 is fixed on the oil storage box 221 near the telescopic cylinder 2302. The oiling part 220 is located in the stamping die 210, and the oiling part 220 is far away from the bottom of the stamping die 210. The oiling part 220 does not affect the stamping operation of the stamping die 210.

[0090] The oiling seat 2211 is a hollow arc-shaped plate with a hollow interior and an opening at the top and two flat ends. The oiling seat 2211 can rotate around the stamping die 210. The axis of the oiling seat 2211 coincides with the axis of the fixed block 231, that is, the oiling seat 2211 coincides with the axis of the stamping die 210. The oiling seat 2211 is communicated with the interior of the oil storage box 221. A plurality of oil outlet holes are provided on the inner side surface of the oiling seat 2211. A short-hair brush is fixed at each oil outlet hole to facilitate oiling the surface of the stamping die 210, and the short-hair brush is not easy to absorb the stamping oil. The air outlet end of the vent pipe 243 extends into the oil storage box 221. The vent pipe 243 is a hose and does not affect the expansion and contraction of the oil storage box 221. The air storage box 221 is pressurized by the vent pipe 243 to make the stamping oil overflow from the oil outlet hole.

[0091] The inner side surface of the oiling seat 2211 includes a convex surface and a concave surface. The movement of the oil storage box 221 drives the oiling seat 2211 to move. The convex surface of the oiling seat 2211 after movement can contact the inner surface of the stamping die 210, and the concave surface of the oiling seat 2211 after movement can contact the outer surface of the stamping die 210. The oiling seat 2211 can cover the oiling range of the stamping die 210. That is to say, the stamping oil in the oil storage box 221 can be smeared on the inner and outer surfaces of the stamping die 210 and oiled at the same time after overflowing from the oil outlet.

[0092] It should be noted that the stamping oil on the surface of the stamping die 210 is relatively thin, which does not affect the stamping effect and can also play a role in lubrication and cooling. The stamping die 210 repeatedly contacts the sheet body 130 and causes a large loss. The stamping die 210 is coated with stamping oil every 15 minutes.

[0093] In the above embodiment, the sheet material body 130 is conveyed to the bottom of the stamping assembly 200 by the conveying device 120, and the stamping die 210 is driven down by the stamping device 111 to stamp the sheet material body 130. The stamping die 210 is pressed down and then rises and resets. During the rising process, the driving part 230 moves, driving the oiling part 220 to extend out from under the stamping die 210, and then the oiling seat 2211 is extended by the cylinder 232. Then, the telescopic cylinder 2302 contracts and drives the oiling part 220 to move upward, and the oiling space of the oiling seat 2211 is stuck on the stamping die 210.

[0094] Subsequently, the oiling seat 2211 is driven by the driving motor 2301 to make a circular motion along the bottom of the stamping die 210, and the oil storage box 221 is pressurized through the ventilation pipe 243, so that the stamping oil overflows from the oil outlet and contacts the inner and outer surfaces of the stamping die 210. As the oiling seat 2211 rotates, the surface of the stamping die 210 is oiled and lubricated. Subsequently, the oiling part 220 is driven by the driving part 230 to quickly reset and retract into the stamping die 210. At the same time, the sheet body 130 is pushed forward. After adjusting the next stamping position, the stamping die 210 is stamped again, and the inner and outer surfaces of the stamping die 210 can be oiled without stopping during the stamping process, thereby ensuring the stability of the operation of the stamping die 210 and improving the quality of sheet stamping.

[0095] In some embodiments of the present application, considering that the stamping die 210 is worn out and burrs are generated when it repeatedly contacts the sheet body 130, and the size of the burrs increases when the stamping die 210 withdraws from and cuts into the sheet body 130, thereby increasing the adhesion between the stamping die 210 and the sheet body 130, resulting in incomplete separation of the sheet, affecting the processing quality of the sheet, further improvements are made to the above problems, specifically, as follows: Figures 4 to 8 As shown:

[0096] A grinding seat 222 is fixed on the oil storage box 221. The grinding seat 222 is an arc-shaped plate with a hollow interior and an open top and two flat ends. The axis of the grinding seat 222 coincides with the axis of the oiling seat 2211.

[0097] Diamond particles are evenly spaced and fixed on the inner side of the grinding seat 222 and the bottom surface away from the oil storage box 221. The diamond particles are used to remove burrs on the punching die 210. The diameter of the diamond particles is in the range of 30 μm to 50 μm, which can effectively remove burrs.

[0098] The inner side surface of the grinding seat 222 includes a convex surface and a concave surface. The convex surface of the grinding seat 222 contacts the inner surface of the stamping die 210, and the concave surface of the grinding seat 222 contacts the outer surface of the stamping die 210. The grinding seat 222 can cover the punching surface at the bottom of the stamping die 210, which is convenient for removing burrs on the stamping part of the stamping die 210.

[0099] It is worth noting that when the grinding seat 222 moves at the stamping die 210, the burrs on the stamping die 210 are removed, and the burrs on the stamping die 210 are relatively small in size. During the continuous contact between the diamond particles and the stamping die 210, the burrs are ground into smaller particles by the diamond particles.

[0100] Specifically, if Figures 6 to 8 As shown, a circular air inlet pipe 240 is fixed at the bottom of the fixing block 231, one end of the vent pipe 243 extends into the air inlet pipe 240, and a distribution pipe 241 and a dust suction pipe 242 are fixed on the side of the air inlet pipe 240, and both the distribution pipe 241 and the dust suction pipe 242 can adapt to the expansion and contraction movement of the oil coating part 220;

[0101] One end of the distribution pipe 241 extends into the oiling seat 2211, and the other end of the distribution pipe 241 extends into the air intake pipe 240. A valve is fixed on the distribution pipe 241, and the valve is used to prevent the stamping oil in the oil storage box 221 from flowing back into the distribution pipe 241. One end of the dust suction pipe 242 extends into the grinding seat 222, and the other end of the dust suction pipe 242 extends into the air intake pipe 240. A valve is fixed on the dust suction pipe 242.

[0102] It is worth mentioning that when the ventilation pipe 243 draws air into the air inlet pipe 240, the valve of the distribution pipe 241 is in a closed state, and the valve of the dust suction pipe 242 is open, so that the debris is sucked into the grinding seat 222. When the ventilation pipe 243 draws air into the air inlet pipe 240, the valve of the distribution pipe 241 is open, and the valve of the dust suction pipe 242 is in a closed state, and the gas will not enter the dust suction pipe 242.

[0103] The grinding seat 222 is a hollow arc-shaped plate and has a plurality of through holes evenly spaced on its inner side surface. The through holes facilitate the entry of grinding chips into the grinding seat 222. That is, when the grinding seat 222 is evacuated, the grinding chips generated by grinding can enter the grinding seat 222 through the through holes, making it easy to clean the grinding chips and clean the surface of the stamping die 210 at the same time.

[0104] It should be noted that when the stamping die 210 is oiled, the burrs on the stamping die 210 are removed first. At this time, the stamping oil on the stamping die 210 is basically consumed, and the surface of the stamping die 210 is dry, which is convenient for collecting debris. The driving part 230 drives the oiling part 220 to grind the stamping die 210, and the vent pipe 243 first extracts air from the air inlet pipe 240 to collect debris, and then the stamping die 210 is oiled by the oiling seat 2211. Or, when burrs appear on the stamping die 210 but it is not time to oil, only the burrs on the stamping die 210 are removed, and then the driving part 230 drives the oiling part 220 to reset. At this time, the vent pipe 243 does not work, and the debris adheres to the stamping die 210, which can increase the contact strength between the stamping die 210 and the sheet body 130, and improve the stamping effect while removing the burrs of the stamping die 210 without stopping the machine.

[0105] On the basis of the above embodiment, the driving part 230 drives the grinding seat 222 to contact the inner and outer surfaces of the stamping knife die 210. At this time, the stamping knife die 210 is located in the grinding space of the grinding seat 222, and the diamond particles on the inner side of the grinding seat 222 contact the surface of the stamping knife die 210. As the driving motor 2301 drives the oiling part 220 to rotate, the diamond particles on the grinding seat 222 contact the punching surface of the stamping knife die 210, and the burrs on the punching surface of the stamping knife die 210 are removed. At the same time, the ventilation pipe 243 draws air into the air inlet pipe 240 to suck the debris into the grinding seat 222, so that the burrs on the stamping knife die 210 can be removed and cleaned without stopping the machine, thereby reducing the burden of subsequent cleaning and ensuring the stability of use.

[0106] In some embodiments of the present application, Figures 9 to 12 As shown, the grinding seat 222 includes an inner grinding plate 2221 and an outer grinding plate 2222;

[0107] The inner grinding plate 2221 is a hollow arc-shaped plate and is fixed on the oil storage box 221 near the fixed block 231. The outer arc surface of the inner grinding plate 2221 contacts the inner side surface of the punching die 210, and the dust suction pipe 242 extends into the inner grinding plate 2221.

[0108] The outer grinding plate 2222 is an arc-shaped plate with a hollow interior and is located on the oil storage box 221 away from the fixed block 231. The inner grinding plate 2221 and the outer grinding plate 2222 are parallel and their axes coincide. The inner arc surface of the outer grinding plate 2222 contacts the outer side surface of the stamping die 210, and the diamond particles are fixed on the outer arc surface of the inner grinding plate 2221 and the inner arc surface of the outer grinding plate 2222.

[0109] It is easy to understand that the inner grinding plate 2221 grinds the inner side surface of the stamping die 210 , and the outer grinding plate 2222 grinds the inner side surface of the stamping die 210 .

[0110] Specifically, if Figures 9 to 12 As shown, a telescopic tube 2224 is fixed at the bottom between the inner grinding plate 2221 and the outer grinding plate 2222, and there is a gap between the telescopic tube 2224 and the oil storage box 221, that is, the outer grinding plate 2222 and the telescopic tube 2224 are not connected to the oil storage box 221, and the inner grinding plate 2221 and the outer grinding plate 2222 are connected to each other through the telescopic tube 2224;

[0111] A support plate is fixed on the oil storage box 221 near the outer grinding plate 2222, and a gas soft bag 2223 is fixed on one side of the support plate near the outer grinding plate 2222. The free end of the gas soft bag 2223 is fixed to the outer grinding plate 2222. After the gas soft bag 2223 is expanded, it can push the outer grinding plate 2222 to approach the stamping die 210.

[0112] An air supply pipe 2411 is fixed on the distribution pipe 241 near the fixed block 231, and the free end of the air supply pipe 2411 extends into the gas bag 2223. The connection between the air supply pipe 2411 and the gas bag 2223 is airtightly fixed, and the gas bag 2223 is inflated through the air supply pipe 2411. A valve is fixed on the air supply pipe 2411, and the valve at the distribution pipe 241 is close to the oiling seat 2211. In other words, the valve of the distribution pipe 241 will not hinder the air in and out of the air supply pipe 2411.

[0113] It is worth noting that when grinding burrs on the surface of the stamping die 210, when the valve of the air supply pipe 2411 is opened, the other valves are closed, and the air in the gas bag 2223 is inflated to adjust the contact force between the outer grinding plate 2222 and the stamping die 210. After the contact force between the outer grinding plate 2222 and the stamping die 210 is increased, the air intake is stopped, and the valve of the air supply pipe 2411 is closed. Then, the valve of the dust suction pipe 242 is opened to collect the burrs generated by grinding.

[0114] On the basis of the above embodiment, when the size of the burrs on the stamping die 210 is large, air is introduced into the air inlet pipe 240 through the ventilation pipe 243, the valve on the air supply pipe 2411 is opened, and the other valves are closed, and the gas enters the gas soft bag 2223, causing the gas soft bag 2223 to expand and push the outer grinding plate 2222 to approach the stamping die 210, thereby increasing the contact force between the outer grinding plate 2222 and the stamping die 210, which can better remove the burrs on the surface of the stamping die 210 and ensure the stability of the use of the stamping die 210.

[0115] In some embodiments of the present application, Figures 13 to 17 As shown, the stamping assembly 200 further includes a chip collecting portion 250;

[0116] The chip collecting portion 250 includes a discharge bin 252;

[0117] A branch pipe 2521 is fixed to the side of the discharge bin 252 close to the oil storage box 221;

[0118] A spray seat 223 is fixed to the oil storage box 221 near the sheet body 130. The spray seat 223 is an arc-shaped plate with a hollow interior and is filled with anti-corrosion liquid. The anti-corrosion liquid is a dry film oil. The anti-corrosion liquid is used to protect the sheet after stamping to avoid corrosion of the sheet, and the anti-corrosion liquid can form a film quickly after spraying. An atomizing nozzle 2231 is fixed to the bottom of the spray seat 223, and the free end of the branch pipe 2521 extends into the spray seat 223, and the pressure in the spray seat 223 is increased through the branch pipe 2521.

[0119] It is worth noting that the stamped sheet material body 130 needs to be stored in a designated place to facilitate subsequent transportation or reprocessing. In order to prevent the surface of the sheet material body 130 from being oxidized, it is usually necessary to protect its surface.

[0120] There are two atomizing nozzles 2231, one atomizing nozzle 2231 is parallel to the sheet body 130, and the atomizing nozzle 2231 is used to spray the periphery of the circular metal sheet, and the spray end of the other atomizing nozzle 2231 is inclined toward the fixed block 231, and the atomizing nozzle 2231 is used to spray the middle part of the circular metal sheet, and there is a staggered spraying area between the two atomizing nozzles 2231, so as to fully spray the surface of the circular metal sheet.

[0121] It is worth noting that, in the initial state, the discharge bin 252 is filled with particles, and the particles in the discharge bin 252 are sent to the spray seat 223 through the delivery pipe 253, so that the sprayed antiseptic liquid contains particles.

[0122] In the above embodiment, the driving unit 230 drives the spray seat 223 to descend and extend out of the stamping die 210, and then the driving motor 2301 drives the spray seat 223 to rotate. At the same time, the anti-corrosion liquid containing particles in the spray seat 223 is sprayed out, and the surface of the sheet material body 130 below is rotated and sprayed. After spraying, the driving unit 230 drives the spray seat 223 to reset, which can increase the adhesion between the anti-corrosion liquid and the surface of the sheet material body 130, and improve the protection of the surface of the sheet material body 130.

[0123] In some embodiments of the present application, Figures 13 to 17 As shown, the chip collecting part 250 further includes a feed bin 251 and a feed pipe 253;

[0124] The feed bin 251 is an annular tube and is fixed to the bottom of the fixed block 231. The feed bin 251 is located below the air inlet pipe 240. The discharge bin 252 is an annular tube and is fixed to the bottom of the feed bin 251 away from the air inlet pipe 240. The discharge bin 252 is located below the feed bin 251. One end of the dust suction pipe 242 extends into the inner grinding plate 2221, and the other end of the dust suction pipe 242 extends into the feed bin 251.

[0125] The suction end of the delivery pipe 253 extends into the feed bin 251, and the delivery pipe 253 is connected to an air pump. The air pump of the delivery pipe 253 is fixed on the discharge bin 252. The feed bin 251 is evacuated through the delivery pipe 253 to suck the debris in the inner grinding plate 2221 into the feed bin 251. The air outlet end of the delivery pipe 253 extends into the discharge bin 252. The delivery pipe 253 is ventilated through the air pump to send the debris in the discharge bin 252 into the discharge bin 252.

[0126] It is worth noting that there are multiple oiling parts 220, and the multiple oiling parts 220 are distributed in a ring at the fixed block 231, which improves the efficiency of oiling and polishing. When the stamping die 210 is polished, the debris particles generated by the polishing are collected, and the number of particles in the discharge bin 252 is increased, which can reduce the number of times the particles are added, and the debris can be collected and recycled at the same time.

[0127] In the above embodiment, when deburring the surface of the stamping die 210, air is evacuated from the feed bin 251 through the feed pipe 253, and the debris generated by grinding is sucked into the feed bin 251, and then enters the discharge bin 252 and is sent to the spray seat 223, and a mist of anti-corrosion liquid containing particles is sprayed out through the atomizing nozzle 2231, and the surface of the sheet body 130 is sprayed while grinding, thereby improving work efficiency.

[0128] In some embodiments of the present application, Figures 17 to 24 As shown, a collecting groove 140 is opened in the middle of the workbench 100, and the sheet material body 130 after stamping falls into the collecting groove 140. A lower spray seat 141 is fixed in the collecting groove 140 near the sheet material body 130, and the lower spray seat 141 is filled with antiseptic liquid;

[0129] The inner side of the lower spray seat 141 is evenly spaced and fixed with a plurality of nozzles 1411. The nozzles 1411 do not contact the falling sheet material body 130, and the nozzles 1411 do not hinder the falling of the sheet material body 130. The spray end of each nozzle 1411 is tilted upward, so as to facilitate comprehensive spraying of the lower surface of the sheet material body 130 with the stamping area.

[0130] An annular groove is formed in the collecting tank 140 near the lower spray seat 141, and a liquid storage box 142 is fixed in the annular groove. The liquid storage box 142 is an annular rubber strip and is filled with antiseptic liquid.

[0131] The inner ring surface of the liquid storage box 142 extends into the collecting trough 140, so that the falling sheet material body 130 can squeeze the liquid storage box 142. A sponge 1421 is fixed on the inner ring surface of the liquid storage box 142. An opening is opened on the liquid storage box 142 near the sponge 1421. The preservative liquid in the liquid storage box 142 seeps into the sponge 1421 from the opening. The sponge 1421 contacts the side of the stamped sheet material body 130. An injection tube is fixed at the liquid storage box 142 to facilitate the addition of preservative liquid into the liquid storage box 142.

[0132] It is worth mentioning that when the spray seat 223 sprays the upper surface of the sheet body 130, the anti-corrosion liquid in the lower spray seat 141 is sprayed out from the nozzle 1411 to spray the lower surface of the sheet body 130. When the punched sheet falls into the collecting trough 140, the oiling part 220 is stored in the stamping die 210, and the driving part 230 drives the oiling part 220 to move downward and push the sheet body 130 through the sponge 1421. At this time, the atomizing nozzle 2231 is closest to the sheet body 130, and the atomizing nozzle 2231 is a soft nozzle, which can prevent the sheet body 130 from jumping chips after stamping.

[0133] Specifically, if Figures 18 to 21 As shown, the outer side of the stamping die 210 is provided with two slide grooves, a fixing frame 2601 is positioned in one slide groove, a sliding connection is formed between the fixing frame 2601 and the slide groove, and a fixing ring 260 is fixed at the bottom of the two fixing frames 2601, and the fixing ring 260 is located outside the stamping die 210;

[0134] The fixing ring 260 is a hollow annular body with a through groove on its inner arc surface. The axes of the fixing ring 260 and the punching die 210 coincide with each other. A movable ring 261 is movably connected to the inner arc surface of the fixing ring 260.

[0135] The movable ring 261 is a circular ring body with a hollow interior and a sealing plate is fixed on the side thereof close to the fixed ring 260. The sealing plate is rotatably sealed with the through groove. One side of the sealing plate is communicated with the interior of the movable ring 261, and the other side of the sealing plate extends into the fixed ring 260. That is, the movable ring 261 is communicated with the interior of the fixed ring 260. A feeding pipe 262 is fixed on the side of the fixed ring 260. The feeding pipe 262 is a bellows that can adapt to the expansion and contraction of the driving part 230. The free end of the feeding pipe 262 extends into the lower spray seat 141. That is to say, when the spray seat 223 sprays the upper surface of the sheet material body 130, the lower spray seat 141 sprays the lower surface of the sheet material body 130.

[0136] A discharge pipe 2611 is fixed to the side of the discharge bin 252, and a reserved groove is opened on the stamping die 210 to facilitate the discharge pipe 2611 to enter and exit the stamping die 210. The remaining end of the discharge pipe 2611 extends into the movable ring 261, and the discharge pipe 2611 is fixedly connected to the movable ring 261. That is to say, when the oil coating part 220 rotates, the movable ring 261 rotates accordingly, and the fixed ring 260 remains stationary.

[0137] In the above embodiment, after the driving unit 230 drives the spray seat 223 to extend out from under the stamping die 210, the driving unit 230 drives the spray seat 223 to rotate and spray the upper surface of the sheet material body 130, and the discharge pipe 2611 rotates with the movable ring 261, and the particles in the discharge bin 252 enter the feeding pipe 262 from the fixed ring 260, and the lower spray seat 141 is pressurized through the feeding pipe 262, and the antiseptic liquid with particles is sprayed from the nozzle 1411 to spray the lower part of the sheet material body 130;

[0138] The sheet material body 130 after stamping falls into the collecting trough 140, and the driving part 230 drives the oiling part 220 to move downward. The oiling part 220 pushes the sheet material body 130 after stamping to move downward and squeeze the liquid storage box 142. The preservative liquid in the liquid storage box 142 seeps into the sponge 1421 from the opening. After the sheet material body 130 passes through the sponge 1421, the side surface of the sheet material body 130 is coated with the anti-corrosion liquid, which can achieve simultaneous spraying of the upper and lower surfaces of the sheet material body 130, saving processing time and improving processing efficiency.

[0139] In some embodiments of the present application, Figure 22 to Figure 24 As shown, a visual inspection device 151 is fixed at the bottom of the collecting trough 140, and the visual inspection device 151 is used to detect cracks in the sheet material body 130. A ring-shaped light source plate 150 is fixed at the bottom of the collecting trough 140 near the visual inspection device 151. The light source plate 150 is used to provide light to the inspected sheet material body 130, so that it can correctly capture and analyze images under the irradiation of light. After the antiseptic liquid with particles is sprayed on the sheet material body 130, the surface of the sheet material body 130 is roughened to form diffuse scattering, which is conducive to the inspection of the visual inspection device 151.

[0140] The workbench 100 has two parallel placement grooves at the bottom, one of which is positioned with a classification box 160. The diameter of the feed port of the classification box 160 is larger than the diameter of the sheet material body 130 after stamping, and the classification box 160 can be withdrawn, so as to facilitate the centralized processing of the collected products. One classification box 160 is used to collect qualified products, and the other classification box 160 is used to collect defective products. The placement groove is parallel to the collection groove 140. A rectangular groove is horizontally opened in the workbench 100. A baffle 172 is fixed in the rectangular groove near the classification box 160 for collecting defective products. The baffle 172 can intercept the sheet material body 130 without affecting the movement of the push plate 171. The placement groove and the collection groove 140 are connected through the inside of the rectangular groove.

[0141] A feeding cylinder 170 is fixed to the side of the workbench 100, the free end of the feeding cylinder 170 extends into the rectangular groove and is fixed with a push plate 171, and the feeding cylinder 170 is connected to the visual inspection device 151 by circuit.

[0142] The push plate 171 is an arc-shaped plate and is located in the collecting groove 140 and above the light source board 150. The push plate 171 is used to intercept the sheet material body 130 after stamping. The sheet material body 130 stays on the push plate 171 after passing through the sponge 1421.

[0143] An electromagnet is fixed on the inner arc surface of the push plate 171 close to the sheet material body 130 , and the electromagnet can magnetically attract the sheet material body 130 when energized.

[0144] In the above embodiment, the sheet material body 130 after stamping enters the collecting trough 140 and falls on the pushing plate 171. The visual inspection device 151 is used to detect cracks at the sheet material body 130. When the inspection is normal, the pushing plate 171 is pushed by the feeding cylinder 170 to send the sheet material body 130 into the classification box 160 for collecting qualified products, and then reset. When the inspection is abnormal, the electromagnet on the pushing plate 171 is energized to adsorb the sheet material body 130, and the feeding cylinder 170 contracts and drives it close to the classification box 160 for collecting defective products. After the sheet material body 130 reaches the top of the classification box 160, the electromagnet is de-energized, and the feeding cylinder 170 continues to contract to intercept the sheet material body 130 through the baffle 172, so that it falls into the designated classification box 160. This can realize the classification of the stamped sheet material body 130 during the stamping process, reduce the subsequent screening burden, and improve the use efficiency.

[0145] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
