[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the present invention, a camera and a pressure sensor are provided. The camera can photograph the sharp edges of the engine hood and the back of the sharp edges, and transmit the photographing results to the background control system. The background control system can detect the surface quality of the engine hood, the sharp edges and the back of the sharp edges through graphic comparison, complete the quality inspection of the engine hood during the production process, and can also evaluate the wear condition of the upper die according to the stamping condition of the back of the sharp edge, so that the staff can maintain the upper die more timely, prevent the upper die from being worn and the staff from maintaining it untimely, resulting in the batch generation of defective products and waste of production raw materials;

[0018] Two rotating rollers are respectively abutted against the outer walls of the lower die and the upper die. When the upper die and the lower die do not shift in position, the pressure value measured by the pressure sensor is zero. When the upper die and the lower die shift in position and cannot be aligned, at this time, the upper die or the lower die will squeeze the spring telescopic rod, and the spring telescopic rod squeezes the pressure sensor. When the pressure value measured by the pressure sensor exceeds the preset range, it indicates that the upper die and the lower die have shifted. At this time, the stamping of the engine hood is immediately stopped and the staff is notified for repair. In this way, the use safety of the upper die and the lower die can be ensured, and at the same time, the production quality of the engine hood is guaranteed.

[0019] In the present invention, a connecting block and a moving block are provided. The edge of the engine hood is clamped by the moving block, and then the two connecting blocks move closer to each other. The pressure sensor can monitor the pressure received by the engine hood. By observing the change of the surface of the engine hood when it is squeezed within the preset pressure value range, the quality inspection of the engine hood can be completed. By continuously increasing the pressure on the engine hood until the engine hood is damaged, the force limit of the engine hood can also be detected, increasing the diversity of the use functions of the device.

[0020] In the present invention, a movable block and a cleaning plate are provided. The two movable blocks move to the sharp edges of the engine hood, and then the third electric telescopic rod drives the cleaning plate to move towards the sharp edges, so that the cleaning plate can squeeze the sharp edges of the engine hood. By controlling the extending force of the third electric telescopic rod, the squeezing force of the cleaning plate on the sharp edges of the engine hood can be changed, and by observing the change of the sharp edges of the engine hood under the preset squeezing force, the production quality inspection of the sharp edges of the engine hood can be completed;

[0021] The cleaning plate can move along the length direction of the movable block. Combining the movement of the movable block driven by the second electric telescopic rod and the extending movement of the cleaning plate driven by the third electric telescopic rod, the cleaning plate can move at the die cores of the upper die and the lower die. Then, the dust suction fan connected to the cleaning plate is turned on, so that the cleaning plate can suck the metal debris at the die cores of the upper die and the lower die, complete the removal of the metal debris in the upper die and the lower die, prevent the existence of metal debris in the die cores of the upper die and the lower die from affecting the production quality of the engine hood, and increase the use convenience of the device;

[0022] When the upper mold and the lower mold need to be transferred, at this time, the first electric telescopic rod drives the movable block to extend upward until the top of the movable block rises to the top of the upper mold. Subsequently, the second electric telescopic rod drives the movable block to move in the direction of extending towards the upper mold, so that the movable block abuts against the top of the upper mold. By the movable block abutting against the top of the upper mold, the fixation of the upper mold and the lower mold can be completed during the transfer process of the upper mold and the lower mold, preventing the upper mold and the lower mold from moving during the transfer process and causing damage to the mold cores inside the upper mold and the lower mold.

The detection mechanism can perform an anti-extrusion test on the engine hood and can also perform an inclination test on the upper die 3 and the lower die 2 to prevent the upper die 3 and the lower die 2 from tilting, resulting in the failure of engine hood production and the damage of the die cores of the upper die 3 and the lower die 2.

[0036] As a technical optimization solution of the present invention, first electric telescopic rods 4 are embedded and installed at both ends of the top of the mounting plate 1. The telescopic ends of the first electric telescopic rods 4 face upward, and the telescopic ends of the first electric telescopic rods 4 are connected to the bottom of the mounting blocks 7. The mounting blocks 7 can be driven to lift by the first electric telescopic rods 4.

[0037] As a technical optimization solution of the present invention, second electric telescopic rods 5 are embedded and installed on the mounting blocks 7. The telescopic ends of the second electric telescopic rods 5 face the lower die 2. The telescopic ends of the second electric telescopic rods 5 movably penetrate through the mounting blocks 7, and the telescopic ends of the second electric telescopic rods 5 are connected to the movable blocks 6. The movable blocks 6 can be driven to move by the second electric telescopic rods 5.

[0038] As a technical optimization solution of the present invention, the auxiliary mechanism includes a third electric telescopic rod 15 and a cleaning plate 16. A first slot 8 is formed through the top of the movable block 6. The third electric telescopic rod 15 is movably installed inside the first slot 8. The telescopic end of the third electric telescopic rod 15 on one movable block 6 faces upward, and the telescopic end of the third electric telescopic rod 15 on the other movable block 6 faces downward. The telescopic end of the third electric telescopic rod 15 is equipped with a cleaning plate 16. A second slot 17 is formed on the side of the cleaning plate 16 away from the third electric telescopic rod 15, and a through hole 18 is formed through the bottom end of the inner wall of the second slot 17. The cleaning plate 16 can suck out the metal debris inside the upper die 3 and the lower die 2, complete the removal of the metal debris in the upper die 3 and the lower die 2, prevent the existence of metal debris in the cores of the upper die 3 and the lower die 2 from affecting the production quality of the engine hood, increase the use convenience of the device. The third electric telescopic rod 15 can drive the cleaning plate 16 to extend, so that the cleaning plate 16 can more conveniently suck out the metal debris inside the upper die 3 and the lower die 2. By pressing the sharp edges of the engine hood under a preset extrusion force by the cleaning plate 16, the quality of the stamping sharp edges of the engine hood can be detected.

[0039] As a technical optimization solution of the present invention, first chutes 13 are horizontally formed on both sides of the inner wall of the first slot 8. First electric sliders 14 are slidably installed inside the first chutes 13. One side of the first electric slider 14 close to the third electric telescopic rod 15 is connected to the third electric telescopic rod 15. By the sliding of the first electric slider 14 in the first chute 13, the third electric telescopic rod 15 can be driven to move inside the first slot 8.

[0040] As a technical optimization solution of the present invention, a plurality of cameras 9 are evenly installed on the top of the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing upward, and a plurality of cameras 9 are evenly installed on the bottom of the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing downward. Through the cameras 9, the appearance of the engine hood can be detected, and the quality control of the sharp edges of the engine hood can be completed.

[0041] As a technical optimization solution of the present invention, third slots 20 are opened at both ends of the side of the movable block 6 close to the lower die 2. A spring telescopic rod 19 is movably installed inside the third slots 20. A pressure sensor 23 is installed at the bottom end of the inner wall of the third slots 20. One end of the spring telescopic rod 19 close to the pressure sensor 23 is connected to the pressure sensor 23, and the end of the spring telescopic rod 19 far from the pressure sensor 23 is connected to the connecting block 10. The rotating roller 12 below the connecting block 10 abuts against the outer wall of the side of the lower die 2, and the rotating roller 12 above the connecting block 10 can abut against the outer wall of the upper die 3. After the upper die 3 is pressed down, the two rotating rollers 12 respectively abut against the outer walls of the lower die 2 and the upper die 3. When the upper die 3 and the lower die 2 do not shift in position, the pressure value measured by the pressure sensor 23 is zero. When the upper die 3 and the lower die 2 shift in position and cannot be aligned, at this time, the upper die 3 or the lower die 2 will squeeze the spring telescopic rod 19, and the spring telescopic rod 19 squeezes the pressure sensor 23. When the pressure value measured by the pressure sensor 23 exceeds the preset range, it means that the upper die 3 and the lower die 2 have shifted. At this time, the stamping of the engine hood is immediately stopped and the staff is notified for maintenance. In this way, the use safety of the upper die 3 and the lower die 2 can be guaranteed, and at the same time, the production quality of the engine hood is ensured.

[0042] As a technical optimization solution of the present invention, stable sliding grooves 21 are horizontally opened on both sides of the inner wall of the third slots 20. A stable sliding block 22 is slidably installed inside the stable sliding grooves 21. One side of the stable sliding block 22 close to the spring telescopic rod 19 is connected to the spring telescopic rod 19. By the sliding of the stable sliding block 22 inside the stable sliding grooves 21, the movement of the spring telescopic rod 19 is made more stable.

[0043] As a technical optimization solution of the present invention, the detection mechanism includes a moving block 11 and a rotating roller 12. Two moving blocks 11 are movably installed on the side of the connecting block 10 close to the lower die 2. The two moving blocks 11 are both in a horizontal state. A rotating roller 12 is rotatably installed on the side of the moving block 11 close to the lower die 2. The rotating roller 12 enables the upper die 3 to be pressed down normally even in the case of deviation, ensuring the stability of the operation of the device. The moving block 11 can clamp the engine hood, making the device more stable when performing a squeezing test on the engine hood and increasing the stability of the use function of the device.

[0044] As a technical optimization solution of the present invention, second sliding grooves 24 are vertically opened at both ends of the side of the connecting block 10 close to the lower die 2. A second electric slider 25 is installed on the side of the moving block 11 close to the second sliding grooves 24. The second electric slider 25 is slidably installed inside the second sliding grooves 24. By the sliding of the second electric slider 25 inside the second sliding grooves 24, the moving block 11 can be driven to move.

[0045] When the present invention is in use, the upper die 3 and the lower die 2 in the device are applicable to the stamping of automobile hoods, and the upper die 3 and the lower die 2 are existing mature technologies, so the specific working principle thereof will not be elaborated too much. All the electric mechanisms in the device are powered by connecting to an external power supply through wires. A control system is provided on the outer side of the device to control all the electric mechanisms in the device. One side of the opening 18 away from the second slot 17 is externally connected to a dust suction fan preset outside the device through a conduit. The specific installation and daily working mode of the conduit are existing mature technologies, so no more elaboration will be made on it.

[0046] The sheet metal to be stamped is placed into the lower die 2 by a manipulator. Subsequently, the upper die 3 is pressed down by a hydraulic device. When the upper die 3 is pressed to a preset position, the hood is formed inside the lower die 2. Then the upper die 3 moves upward away from the lower die 2. Subsequently, the manipulator takes out the stamped hood, completing the stamping of the hood.

[0047] During the process of the manipulator taking out the stamped hood, the hood passes by the side where the camera 9 is installed above the movable block 6, with the sharp edges stamped on the hood facing downward. At this time, the camera 9 can take pictures of the sharp edges of the hood and transmit the taken pictures to the background control system. The background control system compares the pictures taken at this time with the standard pictures to complete the detection of the stamping quality of the sharp edges of the hood, increasing the usability of the device.

[0048] During the stamping and taking out process of the hood, the device can adopt a usage mode of randomly inspecting the hood at preset time intervals. The inspection method is that when the preset interval time arrives, after the upper die 3 rises and disengages from the lower die 2, the manipulator does not take the hood. At this time, the movable block 6 with the camera ⑨ installed below rises to a position above the bottom of the lower die 2 through the extension of the first electric telescopic rod 4. Subsequently, the second electric telescopic rod 5 drives the movable block 6 to extend towards the lower die 2. During the extension of the movable block 6, the camera 9 can take pictures of the back of the sharp edges of the hood and transmit the shooting results to the background control system. The background control system can detect the back of the hood and the back of the sharp edges through graphic comparison, and can also evaluate the wear condition of the upper die 3 according to the stamping condition of the back of the sharp edges, so that the staff can maintain the upper die 3 more timely, preventing the upper die 3 from being worn and the staff not maintaining it in time, resulting in the batch generation of defective products and wasting production raw materials. Then the movable block 6 makes a reset movement to return to its original position.

[0049] During the debugging process of the upper die 3 and the lower die 2, the hood stamped during the debugging process is photographed by the cameras 9 on the two movable blocks 6, and then compared through the background control system. The die cores of the upper die 3 and the lower die 2 can also be adjusted according to the comparison results, so that the upper die 3 and the lower die 2 can better meet the production standards, increasing the convenience of using the device.

[0050] During the stamping process of the hood, the second electric telescopic rod 5 drives the movable block 6 to extend downward toward the lower die 2. The movable block 6 extends to a preset position, so that the rotating roller 12 below the connecting block 10 abuts against the outer wall of the side of the lower die 2, and the rotating roller 12 above the connecting block 10 can abut against the outer wall of the upper die 3. After the upper die 3 presses down, the two rotating rollers 12 respectively abut against the outer walls of the lower die 2 and the upper die 3. When the upper die 3 and the lower die 2 do not shift in position, the pressure value measured by the pressure sensor 23 is zero. If the upper die 3 and the lower die 2 shift in position and cannot be aligned, at this time, the upper die 3 or the lower die 2 will squeeze the spring telescopic rod 19, and the spring telescopic rod 19 squeezes the pressure sensor 23. When the pressure value measured by the pressure sensor 23 exceeds the preset range, it means that the upper die 3 and the lower die 2 have shifted. At this time, the stamping of the hood is immediately stopped and the staff is notified for maintenance. In this way, the use safety of the upper die 3 and the lower die 2 can be guaranteed, and at the same time, the production quality of the hood is ensured.

[0051] During the production process of the hood, a sampling inspection method is adopted to detect the stamping quality of the hood. The specific operation method of the detection is as follows: after the stamping of the hood is completed, the upper die 3 rises to a preset height position. At this time, the hood bounces up through the ejection device in the lower die 2. Under the extension of the first electric telescopic rod 4, the bottoms of the two movable blocks 6 move above the top of the lower die 2. The second electric telescopic rod 5 drives the movable block 6 to move toward the lower die 2 until the connecting block 10 abuts against the edge of the hood. At this time, the two moving blocks 11 move closer to each other through the sliding of the second electric slider 25 in the second chute 24 until the two moving blocks 11 clamp and fix the edge of the hood. Then, the first electric telescopic rod 4 extends upward. After the hood rises to a preset height position, the two second electric telescopic rods 5 extend, so that the two connecting blocks 10 squeeze the hood. At this time, the pressure sensor 23 can monitor the pressure received by the hood. By observing the changes on the surface of the hood when it is squeezed within the preset pressure value range, the quality of the hood can be detected. By continuously increasing the pressure on the hood until the hood is damaged, the force limit of the hood can also be detected, increasing the diversity of the use functions of the device.

[0052] After the production of the engine hood is completed, sampling inspection can be adopted to conduct quality inspection on the sharp edges of the engine hood. The specific inspection method is as follows: when the engine hood is grabbed by the manipulator and moves upward after stamping, when the engine hood rises to the preset height position, at this time, the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing upward moves to the lower part of the engine hood, and the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing downward moves to the upper part of the engine hood, and the two movable blocks 6 move to the sharp edges of the engine hood. Subsequently, the third electric telescopic rod 15 drives the cleaning plate 16 to move towards the sharp edge, so that the cleaning plate 16 can squeeze the sharp edge of the engine hood. By controlling the extension force of the third electric telescopic rod 15, the extrusion force of the cleaning plate 16 on the sharp edge of the engine hood can be changed, and the change of the sharp edge of the engine hood under the preset extrusion force can be observed, so as to complete the detection of the production quality of the sharp edge of the engine hood.

[0053] After the engine hood is taken out by the manipulator after stamping, the device can adopt the use method of cleaning the upper die 3 and the lower die 2 at preset intervals. The specific operation method is as follows: the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing upward moves to the upper die 3, and the movable block 6 with the telescopic end of the third electric telescopic rod 15 facing downward moves to the lower die 2. Subsequently, through the sliding of the first electric slider 14 in the first chute 13, the cleaning plate 16 can move along the length direction of the movable block 6. Combining the movement of the second electric telescopic rod 5 driving the movable block 6 and the extension movement of the third electric telescopic rod 15 driving the cleaning plate 16, the cleaning plate 16 can move at the die cores of the upper die 3 and the lower die 2. Subsequently, turn on the dust suction fan connected to the cleaning plate 16, so that the cleaning plate 16 can suck the metal debris at the die cores of the upper die 3 and the lower die 2, and complete the removal of the metal debris in the upper die 3 and the lower die 2, preventing the existence of metal debris in the die cores of the upper die 3 and the lower die 2 from affecting the production quality of the engine hood and increasing the use convenience of the device.

[0054] When the upper die 3 and the lower die 2 need to be transferred, at this time, the first electric telescopic rod 4 drives the movable block 6 to extend upward until the top of the movable block 6 rises to the top of the upper die 3. Subsequently, the second electric telescopic rod 5 drives the movable block 6 to move towards the upper die 3, so that the movable block 6 abuts against the top of the upper die 3. By the movable block 6 abutting against the top of the upper die 3, the upper die 3 and the lower die 2 can be fixed during the transfer process, preventing the upper die 3 and the lower die 2 from moving during the transfer process and causing damage to the die cores inside the upper die 3 and the lower die 2.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
