Description

Technical Field

[0001] The invention relates to the technical field of stamping metals, and in particular to a stamping forming device for automobile parts. Background Art

[0002] The automobile production process requires the use of sheet metal parts with special shapes. The stamping of automobile body parts is a vital part of the automobile manufacturing process. With the continuous advancement and innovation of technology, the stamping technology of automobile body parts will continue to develop in the direction of high efficiency, precision and environmental protection.

[0003] Patent publication number CN221754459U discloses an automobile parts stamping machine. The automobile parts stamping machine proposed in the prior art achieves the effect of rapid material discharge and high material discharge efficiency, thereby effectively improving the stamping efficiency and the practicability of the device.

[0004] However, the above prior art has the following technical defects: When installing the plates, the workers are required to manually place the workpiece to be stamped in the die base and work around the stamping area, which means that they need to stay near the high-speed moving punch for a long time. When the stamping equipment is working, the punch moves at an extremely high speed. If a person is too close, he or she may be clamped or hit, causing serious mechanical injuries. In addition, powder will be generated during the stamping process, which will be inhaled by the surrounding workers and affect their health.

[0005] Second, this device contains only one punch head, and the single punch head needs to bear the pressure of all punching operations, which causes the punch head of the equipment to wear more and the failure rate to increase, making it extremely easy to be damaged. At the same time, due to frequent use, the maintenance and maintenance costs of the punch head of the equipment increase, and frequent maintenance will also waste time, thereby affecting the production efficiency of the device.

[0006] In summary, this prior art still has room for improvement in terms of protecting the health of workers and improving production efficiency. Therefore, it is necessary to develop a device that allows workers to load materials and improve production efficiency even when they are away from the stamping position. Summary of the invention

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1 - Fig.15 Embodiments of the present invention are described in detail.

[0040] The embodiment of the present application discloses a stamping and forming device for automobile parts. The feeding mechanism can allow the moving side panel and its surface components to take out the finished product from the mold and put in new workpieces during operation, thereby realizing automatic loading and unloading. At the same time, the conveyor belt is driven to rotate by the components during the side movement, and the workpieces placed on it are transported toward the mold to facilitate the suction cup to grab. Then, the staff only needs to fill the empty space at the end of the conveyor belt. The staff operates in a safe area, away from the risk of mechanical injury, and will not absorb the powder generated by stamping, thereby protecting the health of the staff. Example

[0041] like Figure 1 As shown, it includes two symmetrically arranged frames 1 with windows, an upper plate 7 and a lower plate 6 are respectively installed between the two frames 1, a mold 8 is arranged on the lower plate 6, and a feeding mechanism 2 is arranged between the lower plate 6 and the upper plate 7. The two frames 1 and the lower plate 6 and the upper plate 7 together constitute the device shell, and the feeding mechanism 2 can be used to feed the workpiece into the mold 8.

[0042] like Figure 2 As shown, a stamping mechanism 3 is provided on the upper plate 7, a die groove 11 is provided on the upper side of the die 8, and a feed hole 12 is provided inside the lower plate 6 and the die 8, extending from the center of the inner bottom surface of the die groove 11 to the lower surface of the lower plate 6. The workpiece is placed in the die groove 11, and then the workpiece in the die groove 11 is stamped by the stamping mechanism 3, and the stamping waste is discharged from the feed hole 12.

[0043] like Figure 3 As shown, a downwardly inclined guide plate 10 is installed on the side of the mold 8, and a rear plate 9 is installed between the two frames 1 below the guide plate 10. The collection basket is placed on the rear plate 9 at the lower end of the guide plate 10, and the stamped finished product is placed on the guide plate 10 and falls into the rear plate 9 for collection after being guided.

[0044] like Figure 4-Figure 5 As shown, the feeding mechanism 2 includes a mounting plate 201 located on one side of the mold 8, a side plate 210 is arranged above the mounting plate 201, two rectangular grooves are opened on the side of the side plate 210, and a C-shaped plate 211 is slidably arranged in the two rectangular grooves, and a first electric push rod 214 is installed on the side of the side plate 210, and the end of the telescopic arm is fixedly connected to the C-shaped plate 211. The first electric push rod 214 can drive the C-shaped plate 211 to rise and fall in the rectangular groove by telescoping.

[0045] like Figure 6As shown, two cylinders 212 are symmetrically installed on the lower side of the U-shaped plate 211, and four suction cups 213 are installed on the lower side of the cylinder 212 in a rectangular shape. A negative pressure generator 216 is installed on the upper side of the U-shaped plate 211, and a three-way pipe 215 connected with the two cylinders 212 is installed on the output end of the negative pressure generator 216. When a group of suction cups 213 are covered on the same workpiece, negative pressure is generated in the group of suction cups 213 through the negative pressure generator 216 and the three-way pipe 215, so that the workpiece can be fixed on the four suction cups 213. When the negative pressure on the four suction cups 213 is released, the fixation between the workpiece and the suction cups 213 can be released.

[0046] like Figure 7 As shown, two vertical plates 217 with upper ends fixedly connected to the upper plate 7 are symmetrically installed on one side of the side plate 210, and a group of round rods 218 are installed between the two vertical plates 217. A sliding seat 219 fixedly connected to the side plate 210 is slidingly arranged on the two round rods 218. A second electric push rod 220 with a telescopic arm end fixedly connected to the sliding seat 219 is installed on the side of one of the vertical plates 217. The second electric push rod 220 can drive the sliding seat 219 to slide on the round rod 218 by telescoping, and at the same time drive the side plate 210 to move.

[0047] like Figure 7-Figure 9 As shown, a C-shaped frame 202 is embedded in the upper surface of the mounting plate 201, a group of transmission wheels 209 are rotatably installed between the inner side surfaces of the C-shaped frame 202, a conveyor belt 203 is commonly sleeved on the two transmission wheels 209, and a plurality of evenly distributed support rollers 223 are rotatably installed between the inner walls of the C-shaped frame 202 and between the two transmission wheels 209. The staff places the workpiece on the end of the conveyor belt 203 away from the mold 8, and the rotating transmission wheel 209 drives the conveyor belt 203 to rotate, thereby transporting the workpiece on the conveyor belt 203, and at the same time a group of support rollers 223 are used to support the workpiece through the conveyor belt 203.

[0048] like Figure 8 As shown, a group of synchronous wheels 204 are provided on one side of the C-shaped frame 202, wherein one synchronous wheel 204 is fixedly connected to an end of a transmission wheel 209, and the other synchronous wheel 204 is rotationally connected to the side of the C-shaped frame 202. A synchronous belt 205 is commonly provided on the two synchronous wheels 204. When the synchronous wheel 204 rotationally connected to the side of the C-shaped frame 202 rotates, the synchronous wheel 204 connected to the transmission wheel 209 is driven to rotate through the synchronous belt 205, thereby driving the corresponding transmission wheel 209 to rotate.

[0049] like Figure 8As shown, the end of the synchronous wheel 204 rotatably connected to the side of the U-shaped frame 202 is installed with a first one-way clutch 206, and a feeding gear 207 is installed at one end of the first one-way clutch 206. A feeding rack 208 meshing with the feeding gear 207 is slidably provided on one side of the feeding gear 207. The moving feeding rack 208 drives the feeding gear 207 to rotate, and the rotating feeding gear 207 drives the corresponding synchronous wheel 204 to rotate through the first one-way clutch 206. When the feeding rack 208 moves in the opposite direction to drive the feeding gear 207 to reverse, the corresponding synchronous wheel 204 will not be driven to rotate through the first one-way clutch 206.

[0050] like Figure 7 As shown, a first slide groove 221 is opened on the upper side of the mounting plate 201, and a first L-shaped plate 222 is installed on the side of the side plate 210 and is fixedly connected to the feed rack 208 through the first slide groove 221. The moving side plate 210 drives the feed rack 208 to move through the first L-shaped plate 222.

[0051] In summary, a plurality of mutually contacting workpieces to be punched are arranged on the conveyor belt 203. When the workpiece in the die groove 11 is punched into a finished automobile part, the second electric push rod 220 extends to drive the side plate 210 to move in the opposite direction of the mold 8 until the front group of suction cups 213 is directly above the finished product, and the rear group of suction cups 213 is directly above the workpiece on the conveyor belt 203 closest to the mold 8. The first electric push rod 214 extends to drive the two groups of suction cups 213 to contact the workpiece and the finished product respectively, and the negative pressure generator 216 operates to generate negative pressure in the two groups of suction cups 213 to fix the corresponding workpiece and the finished product on the corresponding group of suction cups 213. Then the first electric push rod 214 shortens to drive the workpiece and the finished product to rise until the finished product is removed. After leaving the die groove 11, the second electric push rod 220 shortens and drives the side plate 210 to move toward the mold 8, and at the same time drives the fixed workpiece and the finished product to move, until the workpiece moves to just above the die groove 11. At this time, the finished product also moves to above the guide plate 10. The first electric push rod 214 continues to extend to send the workpiece into the die groove 11. Then the negative pressure generator 216 releases the negative pressure, releases the fixation of the workpiece and the finished product, and the finished product falls on the guide plate 10, and falls into the collection basket after being guided by it. Then the first electric push rod 214 shortens and drives the suction cup 213 to move out of the die groove 11. Then the second electric push rod 220 shortens and drives the side plate 210 to move in the opposite direction of the mold 8 so that the die groove 11 is just between the two groups of suction cups 213.

[0052] When the side plate 210 moves in the opposite direction to the mold 8, the feeding rack 208 is driven to move through the first L-shaped plate 222, and the moving feeding rack 208 drives the feeding gear 207 to rotate. The rotating feeding gear 207 drives the corresponding synchronous wheel 204 to rotate through the first one-way clutch 206, and drives the conveyor belt 203 to rotate through the transmission wheel 209. The rotating conveyor belt 203 transports the workpiece placed thereon toward the mold 8. At the same time, the staff places the workpiece on the new vacancy caused by the rotation of the conveyor belt 203 to achieve filling. When the mold groove 11 is exactly in the center of the two suction cups 213, the feeding rack 208 is disengaged from the feeding gear 207, and when the side plate 210 moves toward the mold 8, it drives the feeding rack 208 to move in the opposite direction. When the feeding rack 208 moves in the opposite direction to drive the feeding gear 207 to reverse, the corresponding synchronous wheel 204 will not be driven to rotate through the first one-way clutch 206.

[0053] like Figure 10-12 As shown, the stamping mechanism 3 includes a rotating shaft 301 rotatably mounted on the lower side of the upper plate 7, a disc 302 is mounted on the lower end of the rotating shaft 301, and a plurality of groups of vertical rods 306 evenly distributed in a circular shape are arranged above the disc 302. A rectangular block 303 is commonly mounted on the upper ends of two vertical rods 306 in each group, and a return spring 305 is sleeved between the vertical rod 306, the rectangular block 303 and the disc 302. The descending rectangular block 303 drives the corresponding group of vertical rods 306 to descend while compressing the return spring 305, and when the return spring 305 rebounds, it drives the rectangular block 303 and the vertical rod 306 to restore their positions.

[0054] like Fig.11 and Fig.12 As shown, each group of two vertical rods 306 penetrates the disc 302 and is jointly equipped with a punch head 304. A cylinder 307 is installed on the upper side of the upper plate 7 just above the die groove 11. The end of the telescopic arm of the cylinder 307 penetrates the upper plate 7 and is equipped with a pressure plate 308. The cylinder 307 extends and presses down the rectangular block 303 just below through the pressure plate 308, driving the punch head 304 to descend and punch the workpiece in the die groove 11.

[0055] like Fig.12 As shown, the upper end of the rotating shaft 301 extends to the upper side of the upper plate 7 and is installed with a second one-way clutch 315, and the upper end of the second one-way clutch 315 is installed with a rotating gear 312. The rotating rotating gear 312 drives the rotating shaft 301 to rotate through the second one-way clutch 315, and when the rotating gear 312 reverses, it will not drive the rotating shaft 301 to rotate through the second one-way clutch 315.

[0056] like Fig.11As shown, a rectangular rod 309 is installed on one side of the upper rotating gear 312 of the upper plate 7, a connecting seat 310 is slidably provided on the rectangular rod 309, and a rotating rack 311 meshing with the rotating gear 312 is installed on the side of the connecting seat 310. The moving rotating rack 311 drives the rotating gear 312 to rotate, and the rotating rack 311 moving in the opposite direction drives the rotating gear 312 to reverse, and the moving rotating rack 311 will also drive the rectangular rod 309 to slide on the pressure plate 308.

[0057] like Fig.11 As shown, a second slide groove 313 is opened on the upper side of the upper plate 7 on one side of the rectangular rod 309, and a second L-shaped plate 314 is installed on the side of the rotating rack 311 through the second slide groove 313 and fixedly connected to the side plate 210. The connecting seat 310 moving toward the direction of the mold 8 drives the rotating rack 311 to move through the second L-shaped plate 314, and the connecting seat 310 moving in the opposite direction of the mold 8 drives the rotating rack 311 to move in the opposite direction.

[0058] In summary, the cylinder 307 extends and presses down the rectangular block 303 directly below through the pressure plate 308. The descending rectangular block 303 drives the corresponding set of vertical rods 306 to descend while compressing the return spring 305, and at the same time drives the punch head 304 to descend to punch the workpiece in the die groove 11. Then the cylinder 307 shortens and drives the pressure plate 308 to rise to release the downward pressure. When the return spring 305 rebounds, it will drive the rectangular block 303 and the vertical rod 306 to restore their positions, and drive the punch head 304 to move out of the die groove 11.

[0059] When the feeding mechanism 2 is filling, when the side plate 210 moves toward the mold 8, the rotating rack 311 is driven to move through the second L-shaped plate 314, and the moving rotating rack 311 drives the rotating gear 312 to rotate, and the second one-way clutch 315 drives the rotating shaft 301 to rotate sixty degrees, so that an adjacent punch head 304 is directly above the die groove 11, and then the above operation is repeated to allow multiple punch heads 304 to punch in sequence.

[0060] like Figure 13-14 As shown, a fixing plate 317 is installed on the side of the rotating shaft 301 above the upper plate 7, and a fixing mechanism 4 is arranged on the upper plate 7 below the fixing plate 317. The fixing mechanism 4 includes an annular seat 402. A plurality of evenly distributed pin holes 316 are opened on the side of the fixing plate 317. A latch 405 whose lower end is connected to the annular seat 402 is arranged in each pin hole 316. When the latch 405 is inserted into the pin hole 316, the fixing plate 317 and the rotating shaft 301 are fixed. When the latch 405 is removed, the fixing of the rotating shaft 301 can be released.

[0061] like Figure 13-14As shown, a group of slide rods 401 with their lower ends fixedly connected to the upper plate 7 are symmetrically installed on the lower side of the annular seat 402, and the upper ends of the slide rods 401 extend to the upper side of the annular seat 402 and are installed with limit plates 403. A fixed spring 404 is sleeved on the slide rod 401. The lowering of the annular seat 402 will compress the fixed spring 404, and the rebound force of the fixed spring 404 is used to apply a reverse damping force to the annular seat 402.

[0062] like Figure 13-14 As shown, a connecting rod 406 is installed on the side of the annular seat 402, and a slider 407 is slidably arranged on the connecting rod 406. A third sliding groove 408 is opened on the upper side of the upper plate 7 below the slider 407, and a third L-shaped plate 409 is installed on the lower side of the slider 407, which passes through the third sliding groove 408 and is fixedly connected to the U-shaped plate 211. The moving third L-shaped plate 409 drives the slider 407 to slide on the connecting rod 406, and the descending third L-shaped plate 409 drives the annular seat 402 to descend together with the slider 407 and the connecting rod 406.

[0063] In summary, the first electric push rod 214 extends to allow the C-shaped plate 211 to drive the suction cup 213 to descend. When the suction cup 213 descends to the first stage, the annular seat 402 drives the pin 405 to disengage from the pin hole 316. When it descends to the second stage, the suction cup 213 contacts the finished product. When the first electric push rod 214 shortens and drives the finished product out of the die groove 11 through the suction cup 213, the height is at the first stage at this time, and the rising pin 405 will not be inserted into the pin hole 316. Then, when the side plate 210 moves in the opposite direction to the mold 8, the moving rotating rack 311 can drive the rotating gear 312 to rotate. Before stamping, the first electric push rod 214 continues to shorten and drives the pin 405 to rise and insert into the pin hole 316 to reinforce the fixed plate 317 and the rotating shaft 301, thereby enhancing the stability during the stamping process. When the stamping is completed, the first electric push rod 214 extends and drives the suction cup 213 to descend to the first stage, thereby releasing the fixation of the rotating gear 312. Example

[0064] Based on the first embodiment, Fig.15 As shown, a blocking mechanism 5 is provided on the rear plate 9, and the blocking mechanism 5 includes two main rods 501 that penetrate the rear plate 9 and are slidably connected thereto, and strip plates 502 are commonly installed at the upper and lower ends of the two main rods 501, and a group of blocking springs 503 are provided between the rear plate 9 and the lower strip plate 502, and the upper and lower ends of the blocking springs 503 are fixedly connected to the rear plate 9 and the lower strip plate 502 respectively. When the collecting basket is placed on the strip plate 502, the strip plate 502 is pressed down by the weight of the collecting basket, and the lower strip plate 502 is driven to descend by the two main rods 501, and the two blocking springs 503 are stretched at the same time.

[0065] like Fig.15As shown, two connecting frames 504 are symmetrically installed on the lower side of the lower strip plate 502, and a baffle 505 for blocking the lower end of the guide plate 10 is commonly installed on the sides of the two connecting frames 504. When the lower strip plate 502 descends, the baffle 505 is driven down by the two connecting frames 504 to release the blockage of the guide plate 10.

[0066] In summary, when the collecting basket is placed on the strip plate 502, the strip plate 502 is pressed down by the weight of the collecting basket, and the lower strip plate 502 is driven down by the two main rods 501, and the two blocking springs 503 are stretched at the same time. When the lower strip plate 502 is lowered, the baffle plate 505 is driven down by the two connecting frames 504, and the blocking of the guide plate 10 can be released. After that, the finished products guided by the guide plate 10 will fall into the collecting basket, and when the collecting basket is removed from the rear plate 9, the elongated springs 503 are stretched. The blocking spring 503 retracts and drives the strip plate 502 to restore its position, and at the same time drives the baffle 505 to re-seal the lower end of the guide plate 10. The finished products falling on the guide plate 10 will be blocked by the baffle 505 to prevent them from sliding out. When the empty collecting basket is pressed on the strip plate 502 again, the baffle 505 will be driven to descend to release the blockage. After that, the finished products accumulated on the guide plate 10 will continue to slide into the collecting basket, and then there is no need to close the device when the collecting basket is replaced, thereby improving the stamping efficiency.

[0067] Working principle of the present invention: S1, material taking and loading, using the feeding mechanism 2 to take out the finished product punched in the die slot 11, and put a new workpiece to be punched into it. Specifically, a plurality of workpieces to be punched that are in contact with each other are arranged on the conveyor belt 203. When the workpiece in the die slot 11 is punched into a finished automotive part, the second electric push rod 220 extends to drive the side plate 210 to move in the opposite direction of the die 8 until a group of suction cups 213 in the front are directly above the finished product, and a group of suction cups 213 in the rear are directly above the workpiece on the conveyor belt 203 closest to the die 8. The first electric push rod 214 extends to drive the two groups of suction cups 213 to contact the workpiece and the finished product respectively, and the negative pressure generator 216 is operated to allow the two groups of suction cups to move in the opposite direction of the die 8. Negative pressure is generated in the suction cup 213, fixing the corresponding workpiece and finished product on the corresponding group of suction cups 213, and then the first electric push rod 214 is shortened to drive the workpiece and the finished product to rise until the finished product is separated from the die groove 11, and the second electric push rod 220 is shortened to drive the side plate 210 to move toward the mold 8, and at the same time drive the fixed workpiece and finished product to move until the workpiece moves to just above the die groove 11. At this time, the finished product also moves to above the guide plate 10, and the first electric push rod 214 continues to extend to send the workpiece into the die groove 11, and then the negative pressure generator 216 releases the negative pressure, releases the fixation of the workpiece and the finished product, and the finished product falls on the guide plate 10 and falls into the collection basket after being guided by it.

[0068] S2, staff filling, when there is a vacancy on the upper side of the conveyor belt 203, the staff puts a new workpiece into the vacancy, specifically, the first electric push rod 214 shortens and drives the suction cup 213 to move out of the die groove 11, then the second electric push rod 220 shortens and drives the side plate 210 to move in the opposite direction of the mold 8, so that the die groove 11 is just between the two groups of suction cups 213, when the side plate 210 moves in the opposite direction of the mold 8, the first L-shaped plate 222 drives the feeding rack 208 to move, drives the feeding gear 207 to rotate, the rotating feeding gear 207, and drives the corresponding synchronous wheel 204 to rotate through the first one-way clutch 206, and drives the transmission wheel 209. The conveyor belt 203 is driven to rotate, and the rotating conveyor belt 203 transports the workpiece placed thereon toward the mold 8, so that the head workpiece is close to the mold 8. At the same time, the staff places the workpiece on the new empty space at the end of the row caused by the rotation of the conveyor belt 203 for filling. When the mold groove 11 is exactly in the center of the two suction cups 213, the feed rack 208 is disengaged from the feed gear 207, and when the side plate 210 moves toward the mold 8, it drives the feed rack 208 to move in the opposite direction. When the feed rack 208 moves in the opposite direction to drive the feed gear 207 to reverse, the corresponding synchronous wheel 204 will not be driven to rotate through the first one-way clutch 206.

[0069] S4, punch head change, when the inner side plate 210 of the feeding mechanism 2 moves toward the mold 8, it drives the rotating shaft 301 to rotate, and replaces the punch head 304 directly above the die groove 11. Specifically, when the side plate 210 moves toward the mold 8 during the operation of the feeding mechanism, the rotating rack 311 is driven to move by the second L-shaped plate 314, and the moving rotating rack 311 drives the rotating gear 312 to rotate, and the rotating shaft 301 is driven to rotate sixty degrees by the second one-way clutch 315, so that an adjacent punch head 304 is directly above the die groove 11.

[0070] S4, structural fixation, using a fixing mechanism to fix the rotating shaft 301 in the punching mechanism 3, specifically, before punching, the first electric push rod 214 is shortened to drive the pin 405 to rise and insert into the pin hole 316 to reinforce the fixed plate 317 and the rotating shaft 301, and enhance the stability during the punching process. When the punching is completed, the first electric push rod 214 is extended to drive the suction cup 213 to descend to the first stage, and the fixing of the rotating gear 312 is released. Before that, the first electric push rod 214 is extended to allow the U-shaped plate 211 to be inserted into the pin hole 316. It will also drive the suction cup 213 to descend. When the suction cup 213 descends to the first stage, the annular seat 402 drives the pin 405 to disengage from the pin hole 316. When it descends to the second stage, the suction cup 213 contacts the finished product. When the first electric push rod 214 shortens and drives the finished product out of the mold cavity 11 through the suction cup 213, the height is at the first stage at this time, and the rising pin 405 will not be inserted into the pin hole 316. Then, when the side plate 210 moves in the opposite direction to the mold 8, the moving rotating rack 311 can drive the rotating gear 312 to rotate.

[0071] S5, workpiece stamping, use the stamping mechanism 3 to stamp the workpiece in the die slot 11, specifically, the cylinder 307 is extended to press down the rectangular block 303 directly below through the pressure plate 308, and the descending rectangular block 303 drives the corresponding set of vertical rods 306 to descend while compressing the reset spring 305, and at the same time drives the punching head 304 to descend to stamp the workpiece in the die slot 11, then the cylinder 307 is shortened to drive the pressure plate 308 to rise to release the downward pressure, and when the reset spring 305 rebounds, it will drive the rectangular block 303 and the vertical rod 306 to restore their positions, and drive the punching head 304 to move out of the die slot 11, and then repeat the operation from S1 to achieve continuous stamping.
