Description

Technical Field

[0001] This invention relates to the field of anomaly monitoring and protection technology, specifically to an anomaly monitoring and protection device for aluminum shell production. Background Technology

[0002] In the production of modern aluminum shells, stamping machines are widely used. "Cost reduction, quality improvement, and efficiency enhancement" are the main means for enterprises to improve their profitability. Stamping is a forming process that applies external force to sheet metal, strip, tube, and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Aluminum shell production usually adopts continuous stamping, which means that the punch presses continuously at a certain frequency. The robot changes the workpiece or adjusts its position during the interval between two punches. However, operators need to check the aluminum shells for stamping defects every 20-30 times, such as mold marks, dents, scratches, bulges, corner collapse, and edge curling. The workload is relatively large, and the waste generated during stamping can easily cause injury. Moreover, the abnormalities in production cannot be detected by the naked eye in the shortest time, which can easily lead to waste of resources. Although many machine tools are now equipped with monitoring equipment, the waste will continuously damage the monitoring equipment, resulting in a short service life. When large pieces of waste are splashed, they can directly damage the monitoring equipment. Summary of the Invention

[0008] Preferably, the protective mechanism includes a solenoid valve and a first circular ring. The solenoid valve is installed on the front end face of the air storage chamber. A second air outlet pipe is symmetrically installed on the front end face of the solenoid valve. The other end of the second air outlet pipe is installed on an air chamber opened on the front end face of the punch press. A piston is slidably installed inside the air chamber. Symmetrical tension springs are installed on the side of the piston facing the second air outlet pipe. The other end of the tension springs is installed on the inner wall of the air chamber. A second connecting rod is installed on the side of the piston away from the second air outlet pipe. A sixth circular rod is rotatably installed on the other end of the second connecting rod.

[0010] Preferably, tempered glass is installed on the front end of the punch press corresponding to the internal gear ring.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] I. This invention incorporates an intermittent mechanism and a cleaning mechanism. When the first slider is pressed down, the second slider presses down on the air cylinder to inflate the air storage chamber. Excessive pressure in the air storage chamber is discharged from the nozzle through the pressure relief valve, cleaning debris from the tempered glass. Simultaneously, the rack moves downward in the first slide groove and engages with the ratchet. When it reaches the lowest point, the rack slides inward under the action of the second slide groove on the slide rail. When the first slider rises, the rack and ratchet disengage, allowing multiple presses to clean the tempered glass and remove debris that cannot be removed by gas. This also prevents frequent cleaning from affecting the lifespan of the brush. Furthermore, cleaning is completed when the first slider is pressed down, and ends when it rises, preventing incomplete monitoring.

[0013] II. This invention incorporates a protective mechanism. When splashing debris is detected, the solenoid valve opens, gas enters the gas chamber, the piston is compressed, the tension spring is stretched, and the piston, via the second connecting rod, compresses the handle. The handle drives the internal gear ring to rotate. Since the internal gear ring meshes with the gear, the gear drives the baffle to rotate, thus protecting the fixed frame. When release is required, pressure is released through the pressure relief valve, the tension spring resets, and the tension spring pulls the piston to reset. The piston, via the second connecting rod, pulls the handle, which drives the internal gear ring to rotate. Since the internal gear ring meshes with the gear, the gear drives the baffle to rotate, thus releasing the blockage. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1 to 8 The present invention provides a technical solution: an abnormal monitoring and protection device for aluminum shell production, including a punch press 1 and a first slider 2. A control panel 3 is installed on the front end face of the punch press 1, and an air storage chamber 6 is installed on the rear end face of the punch press 1. An intermittent mechanism 100 is installed behind the first slider 2. A cleaning mechanism 200 for keeping the lens clean is installed on the side of the intermittent mechanism 100 away from the first slider 2. A protective mechanism 300 for preventing the lens from being damaged by impact is installed behind the cleaning mechanism 200.

[0024] In this embodiment, as shown Figure 4 As shown, the intermittent mechanism 100 includes a slide plate 101, the front end of which is mounted on the rear end face of the first slider 2, and a slide rail 102 mounted on the lower end face of the slide plate 101. The slide rail 102 is slidably mounted on the inner wall of the punch press 1. A second slide groove 108 is symmetrically opened on the slide rail 102. A rack 103 is symmetrically slidably mounted on the front end face of the slide rail 102. The rear end face of the rack 103 passes through the second slide groove 108 and is slidably mounted on the punch press 1 through a first slide groove 104 symmetrically opened on the front end face of the punch press 1. A ratchet 106 is rotatably mounted on the front end face of the punch press 1. A pawl 105 is engaged above the ratchet 106. The other end of the pawl 105 is rotatably mounted on the front end face of the punch press 1. A lever 107 is fixedly mounted on the front end face of the ratchet 106.

[0025] The first slider 2 presses downwards, causing the slide plate 101 to move downwards. The slide plate 101 drives the lower slide rail 102 to slide on the punch press 1. The slide rail 102 drives the racks 103 on both sides to move downwards. When the racks 103 engage with the ratchet 106, the ratchet 106 on both sides will rotate inwards by a certain angle. The ratchet 106 drives the lever 107 to rotate, and the ratchet 106 will push the pawl 105 upwards. The pawl 105 will prevent it from rotating. When the first slider 2 reaches the bottom, the rack 103... Under the action of the first slide groove 104 and the second slide groove 108, the slide 103 will slide inward on the slide rail 102. After the stamping is completed, the first slider 2 will drive the slide plate 101 to rise, and the slide plate 101 will drive the slide rail 102 to rise. Since the rack 103 is at the innermost side of the first slide groove 104, the rack 103 will not mesh with the ratchet 106. When the first slider 2 reaches the top, the rack 103 will slide outward on the slide rail 102 under the action of the first slide groove 104 and the second slide groove 108, and the rack 103 will return to its original position.

[0026] Further, such as Figure 4 As shown, the cleaning mechanism 200 includes a first connecting rod 201 and a pressure relief valve 210 symmetrically installed. A second round rod 203 is rotatably mounted on the rear end face of the first connecting rod 201, and the other end of the second round rod 203 is fixedly mounted on the punch press 1. A third round rod 204 is rotatably mounted on the right front end face of the first connecting rod 201. A first round rod 202 is slidably mounted inside the left side of the first connecting rod 201. A third slider 205 is mounted on the rear end face of the first round rod 202. The third slider 205 is slidably mounted on the punch press 1 through a third sliding groove 213 opened on the front end face of the punch press 1. The third slider 205 is further... A fourth round rod 211 is installed at one end, and a spring 207 is installed on the lower end face of the third slider 205. The other end of the spring 207 is fixedly installed on the inner wall of the third slide groove 213 opened on the front face of the punch press 1. A brush 206 is sleeved on the outside of the fourth round rod 211. A fifth round rod 212 is rotatably installed on the rear end face of the brush 206. The other end of the fifth round rod 212 is fixedly installed on the punch press 1. The pressure relief valve 210 is installed on the front face of the air storage chamber 6. A first air outlet pipe 209 is symmetrically installed on the front face of the pressure relief valve 210. A nozzle 208 is installed on the other end of the first air outlet pipe 209. Figure 2 As shown, a second slider 4 is fixedly connected to the rear end face of the slide plate 101 through the punch press 1. An air cylinder 5 is symmetrically installed on the lower end face of the second slider 4. An air inlet pipe 7 is installed on one side of the air cylinder 5, and the other end of the air inlet pipe 7 is installed on the rear end face of the air storage chamber 6. The number of teeth of the ratchet 106 is ten times that of the rack 103. Tempered glass is installed on the front end face of the punch press 1 at the position corresponding to the inner toothed ring 304.

[0027] The sliding plate 101 drives the second slider 4 downward, which in turn squeezes the air cylinder 5 downward. Gas enters the air storage chamber 6 through the air inlet pipe 7. Since the air pressure inside the air storage chamber 6 is constant, when the first slider 2 moves downward, the gas inside the air storage chamber 6 is discharged through the pressure relief valve 210 and then flows through the first air outlet pipe 209 and is discharged from the nozzle 208. This cleans the tempered glass on the punch press 1, preventing debris from remaining on the tempered glass and affecting the monitoring camera. Because it is moving downward at this time, the punching is not yet complete. When the first slider 2 rises, the cleaning is completed and the punching is finished, so it will not delay the monitoring camera from taking pictures to detect abnormalities. Since the number of teeth on the ratchet 106 is ten times that of the rack 103, after ten punches, the lever 107 on the ratchet 106 will push the third round rod 204 upward. The third round rod 204 drives the first connecting rod 203 to move upward. Rod 201 rotates around the second round rod 203. The other end of the first connecting rod 201 moves downward through the first round rod 202, causing the third slider 205 to move downward in the third groove 213. The spring 207 is compressed. At the same time, the fourth round rod 211 moves downward, causing the brush 206 to rotate around the fifth round rod 212. Due to the lever principle, the other end of the brush 206 cleans the tempered glass, causing the debris that cannot be blown away by the gas to fall off. When the next stamping occurs, the lever 107 no longer resists the third round rod 204, the spring 207 extends, and the third slider 205 returns to its original position. Since the first slider 2 moves downward when the lever 107 moves the third round rod 204 upward, the stamping has not yet been completed. When the first slider 2 rises, the cleaning has been completed and the stamping is finished, so it will not delay the monitoring camera from taking pictures to detect abnormalities.

[0028] In this embodiment, as shown Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the protective mechanism 300 includes a solenoid valve 301 and a first ring 312. The solenoid valve 301 is installed on the front end face of the air storage chamber 6. A second air outlet pipe 302 is symmetrically installed on the front end face of the solenoid valve 301. The other end of the second air outlet pipe 302 is installed on an air chamber 303 opened on the front end face of the punch press 1. A piston 307 is slidably installed inside the air chamber 303. A tension spring 318 is symmetrically installed on the side of the piston 307 facing the second air outlet pipe 302. The other end of the tension spring 318 is installed on the inner wall of the air chamber 303. A second connecting rod 308 is installed on the side of the piston 307 away from the second air outlet pipe 302. A sixth round rod 309 is rotatably installed on the other end of the second connecting rod 308. A handle 310 is slidably sleeved on the outside of the sixth round rod 309. An internal gear ring 304 is fixedly installed on the outer wall of one side of the handle 310. The internal gear ring 304 is rotatably installed on the punch press 1. 4. Gears 305, evenly distributed along the circumference, are internally meshed. A baffle 306 is fixedly installed on the rear end face of the gears 305. The rear end face of the baffle 306 is mounted on the punch press 1. Seventh round rods 311 are symmetrically installed on the upper and lower outer walls of the first ring 312. The other end of the seventh round rod 311 is rotatably mounted on the punch press 1. Eighth round rods 313 are symmetrically rotatably installed on the left and right inner walls of the first ring 312. A second ring 316 is installed on the other end of the eighth round rod 313. A fixing frame 317 is installed on the inner wall of the second ring 316. A second pneumatic telescopic rod 315 is installed on the upper outer wall of the fixing frame 317. A first pneumatic telescopic rod 314 is installed on the right outer wall of the fixing frame 317. The other ends of the second pneumatic telescopic rod 315 and the first pneumatic telescopic rod 314 are rotatably mounted on the punch press 1 via a rotating ball. The baffles 306 are of the same thickness and are staggered in sequence.

[0029] When a small vertical adjustment is needed, the second pneumatic telescopic rod 315 extends or retracts, and the fixing frame 317 drives the second ring 316 to rotate around the eighth rod 313 as the center, thus completing the adjustment. When a small horizontal adjustment is needed, the first pneumatic telescopic rod 314 extends or retracts, and the fixing frame 317 drives the first ring 312 to rotate around the seventh rod 311 as the center through the second ring 316 and the eighth rod 313, thus completing the adjustment.

[0030] When there is flying debris during stamping, the monitoring camera will send feedback to the control panel 3. At this time, the control panel 3 will control the solenoid valve 301 to open, and the gas in the gas storage chamber 6 will be discharged through the solenoid valve 301, flow through the second vent pipe 302 and into the gas chamber 303. The gas will compress the piston 307, and the tension spring 318 will be stretched. The piston 307 drives the second connecting rod 308 to compress the handle 310 through the sixth round rod 309. The handle 310 drives the internal gear ring 304 to rotate. Since the internal gear ring 304 and the gear 305 mesh with each other, the gear 305 will drive... The baffle 306 rotates, blocking the front of the mounting bracket 317 to protect the monitoring camera and prevent damage. When it needs to be released, the pressure is released through the pressure relief valve 210, the tension spring 318 contracts, and the piston 307 is reset, which in turn drives the second connecting rod 308 to move. The second connecting rod 308 pulls the handle 310 to reset through the sixth round rod 309. The handle 310 drives the internal gear ring 304 to rotate. Since the internal gear ring 304 and the gear 305 mesh with each other, the gear 305 will drive the baffle 306 to rotate and return to its original position.

[0031] Working principle: First, adjust the corresponding parameters through the control panel 3. Place the monitoring camera inside the mounting bracket 317. Adjust the angle of the mounting bracket 317 slightly by controlling the second pneumatic telescopic rod 315 and the first pneumatic telescopic rod 314. When vertical adjustment is required, the second pneumatic telescopic rod 315 extends or retracts, and the mounting bracket 317 drives the second ring 316 to rotate around the eighth rod 313 as the center, thus completing the adjustment. When horizontal adjustment is required, the first pneumatic telescopic rod 314 extends or retracts, and the mounting bracket 317 drives the first ring 312 to rotate around the seventh rod 311 through the second ring 316 and the eighth rod 313, thus completing the adjustment.

[0032] When stamping is required, the first slider 2 presses downwards, causing the slide plate 101 to move downwards. The slide plate 101 then moves the lower slide rail 102 onto the punch press 1. The slide rail 102 moves the racks 103 on both sides downwards. When the racks 103 engage with the ratchet 106, the ratchet 106 rotates inwards by a certain angle. The ratchet 106 then rotates the lever 107, causing it to push the pawl 105 upwards. The pawl 105 prevents the ratchet from rotating. Simultaneously, the slide plate 101 moves the second slider 4 downwards, which in turn compresses the air cylinder 5. Gas flows from the air inlet pipe 7. Upon entering the air storage chamber 6, when the first slider 2 reaches the bottom, the rack 103 slides inward on the slide rail 102 under the action of the first slide groove 104 and the second slide groove 108. After the stamping is completed, the first slider 2 drives the slide plate 101 to rise, and the slide plate 101 drives the slide rail 102 to rise. Since the rack 103 is at the innermost side of the first slide groove 104, the rack 103 does not mesh with the ratchet 106. When the first slider 2 reaches the top, the rack 103 slides outward on the slide rail 102 under the action of the first slide groove 104 and the second slide groove 108, and the rack 103 returns to its original position.

[0033] Since the air pressure inside the air storage chamber 6 is constant, when the first slider 2 moves downward, the gas inside the air storage chamber 6 will be discharged through the pressure relief valve 210 and then flow through the first air outlet pipe 209 and be discharged from the nozzle 208 to clean the tempered glass on the punch press 1 and prevent debris from being on the tempered glass and affecting the monitoring camera. Because it is moving downward at this time, the punching has not yet been completed. When the first slider 2 rises, the cleaning has been completed and the punching has been completed, so it will not delay the monitoring camera from taking pictures or monitoring abnormalities.

[0034] After repeated stamping, lever 107 pushes the third round rod 204 upwards. The third round rod 204 drives the first connecting rod 201 to rotate around the second round rod 203. The other end of the first connecting rod 201 moves downwards through the first round rod 202, causing the third slider 205 to move downwards in the third slide groove 213. The spring 207 is compressed. At the same time, the fourth round rod 211 drives the brush 206 to rotate around the fifth round rod 212. Due to the lever principle, the other end of the brush 206 cleans the tempered glass, causing debris that cannot be blown away by the gas to fall off. When stamping occurs again, lever 107 no longer resists the third round rod 204, the spring 207 extends, and the third slider 205 returns to its original position. Since the first slider 2 is moving downwards when lever 107 pushes the third round rod 204 upwards, the stamping has not yet been completed. When the first slider 2 rises, the cleaning and stamping have been completed, so it will not delay the monitoring camera from taking pictures and monitoring abnormalities.

[0035] When there is flying debris during stamping, the monitoring camera will send feedback to the control panel 3. At this time, the control panel 3 will control the solenoid valve 301 to open, and the gas in the gas storage chamber 6 will be discharged through the solenoid valve 301, flow through the second vent pipe 302 and into the gas chamber 303. The gas will compress the piston 307, and the tension spring 318 will be stretched. The piston 307 drives the second connecting rod 308 to compress the handle 310 through the sixth round rod 309. The handle 310 drives the internal gear ring 304 to rotate. Since the internal gear ring 304 and the gear 305 mesh with each other, the gear 305 will drive... The baffle 306 rotates, blocking the front of the mounting bracket 317 to protect the monitoring camera and prevent damage. When it needs to be released, the pressure is released through the pressure relief valve 210, the tension spring 318 contracts, and the piston 307 is reset, which in turn drives the second connecting rod 308 to move. The second connecting rod 308 pulls the handle 310 to reset through the sixth round rod 309. The handle 310 drives the internal gear ring 304 to rotate. Since the internal gear ring 304 and the gear 305 mesh with each other, the gear 305 will drive the baffle 306 to rotate and return to its original position.
