[0050] Reference Figure 1 to Figure 7, which is the first embodiment of the present invention, proposes a stable automobile sheet metal trimming and stamping equipment for cutting off the edge waste of the sheet metal, including a stamping device 1; an upper mold 2 is arranged at the stamping end of the stamping device 1; a lower mold 3 is tiltedly arranged in the stamping device 1, located below the upper mold 2, a stamping space is formed between the lower mold 3 and the upper mold 2, and a mounting groove 31 is provided on the lower side of the lower mold 3; a lifting block 4 is lifted and arranged in the mounting groove 31, and the upper surface of the lifting block 4 is combined with the upper surface of the lower mold 3 to form a stamping surface; a first elastic member 5 is arranged in the mounting groove 31, and the two ends of the first elastic member 5 are respectively abutted against the lifting block 4 and the mounting groove 31, so as to provide the lifting block 4 with a force to lift the sheet metal.

[0051] In this embodiment, in order to solve the problem that the automobile roof will deform during blanking after the stamping and trimming is completed in the related art, a stable automobile sheet metal trimming and stamping equipment is designed. The stamping device 1 is a hydraulic stamping machine. The upper die 2 is installed at the stamping end of the stamping device 1 and is made of alloy steel. The lower die 3 is tiltedly arranged in the stamping device 1 and is located below the upper die 2. The lower die 3 has a mounting groove 31 on the lower side. The lifting block 4 can be raised and lowered in the mounting groove 31, and the upper surface and the upper surface of the lower die 3 constitute a stamping surface. The first elastic member 5 is a coil spring, which is arranged in the mounting groove 31, and the two ends abut the lifting block 4 and the bottom of the mounting groove 31 respectively. When the stamping operation is performed, the sheet metal is placed in the stamping space between the lower die 3 and the upper die 2. After the stamping device 1 is started, the upper die 2 moves downward to stamp and trim the sheet metal, and the lifting block 4 is pressed downward to compress the first elastic member 5. After the stamping is completed, the upper die 2 moves upward, and the first elastic member 5 lifts the lifting block 4 to eject the sheet metal.

[0052] The advantage is that the combination of the lifting block 4 and the first elastic member 5 in the trimming and stamping equipment for automobile sheet metal parts has multiple advantages. First, after the stamping is completed, the first elastic member 5 can push the lifting block 4 up to realize the demoulding of the sheet metal parts and improve production efficiency. Second, it avoids the deformation problem of sheet metal parts during traditional unloading, and the ejection force of the lifting block 4 acts evenly on the sheet metal parts to ensure quality. Third, it reduces the labor intensity of operators and makes unloading operations convenient. Fourth, it improves equipment stability and reduces equipment failures and downtime caused by unloading difficulties.

[0053] Furthermore, the lifting block 4 has a guide groove 41, which is divided into a sliding-in section 411, a clamping section 412 and a sliding-out section 413, and is connected end to end in sequence. It also includes a first rocker arm 6, one end of which is hingedly arranged at the bottom of the mounting groove 31, and the other end of the first rocker arm 6 has a clamping portion 61. The guide groove 41 is configured such that after pressing the lifting block 4, the clamping portion 61 passes through the sliding-in section 411 and enters the clamping section 412, so that the lifting block 4 is close to the lower mold 3. After pressing the lifting block 4 again, the clamping portion 61 slides out of the clamping section 412 and the sliding-out section 413, so that the lifting block 4 lifts up the sheet metal.

[0054] In this embodiment, the lifting block 4 is provided with a guide groove 41, which is divided into a slide-in section 411, a clamping section 412 and a slide-out section 413. One end of the first swing arm 6 is hinged at the bottom of the mounting groove 31. The other end of the first swing arm 6 has a clamping portion 61. When the lifting block 4 is pressed, the clamping portion 61 passes through the slide-in section 411 and enters the clamping section 412, and the lifting block 4 is close to the lower mold 3. After the lifting block 4 is pressed again, the clamping portion 61 slides out of the clamping section 412 and the slide-out section 413, so that the lifting block 4 lifts up the sheet metal under the action of the first elastic member 5.

[0055] In actual operation, when the sheet metal is placed on the lower die 3 and ready for stamping, the lifting block 4 is in the initial position. As the operation progresses, if the lifting block 4 needs to be lowered to better fix the position of the sheet metal, the lifting block 4 can be pressed by external force, so that the clamping portion 61 of the first swing arm 6 enters the clamping portion 412 from the sliding section 411, and the lifting block 4 is lowered and close to the lower die 3. When the stamping is completed, the lifting block 4 is pressed again, and the clamping portion 61 slides out of the clamping section 412 and the sliding section 413 in turn. The lifting block 4 moves upward under the elastic force of the first elastic member 5 to lift the sheet metal.

[0056] The advantage is that, through the cooperation of the guide groove 41 and the first swing rod 6, the lifting position of the lifting block 4 can be accurately controlled to meet the requirements of the position of the lifting block 4 in different stamping stages. This structural design makes the movement of the lifting block 4 more stable and reliable, avoids the accidental movement of the lifting block 4 during the stamping process, and ensures the stamping quality. The operator can control the state of the lifting block 4 by a simple pressing operation, which is easy to master and operate, and improves work efficiency.

[0057] Furthermore, after the clamping portion 61 is located at the clamping section 412, the upper surface of the lifting block 4 is higher than the upper surface of the lower mold 3, and it also includes a robotic arm 7; the suction cup device 8 is arranged at the output end of the robotic arm 7; the first telescopic member 9 is arranged above one side of the suction cup device 8, and after the suction cup device 8 sucks the sheet metal and moves it above the lower mold 3, the first telescopic member 9 extends, and the extended end of the first telescopic member 9 presses the lifting block 4 through the sheet metal; after the upper mold 2 slides downward, it abuts against the sheet metal and presses the lifting block 4 again.

[0058] In this embodiment, a mechanical arm 7, a suction cup device 8 and a first telescopic member 9 are provided. The suction cup device 8 is arranged at the output end of the mechanical arm 7, and the first telescopic member 9 is arranged on the suction cup device 8. When the suction cup device 8 sucks the sheet metal and moves it above the lower mold 3, the first telescopic member 9 extends, and its extended end presses the lifting block 4 through the sheet metal. At the same time, after the upper mold 2 slides downward, it will also abut against the sheet metal and press the lifting block 4 again.

[0059] During the production process, the robot arm 7 drives the suction cup device 8 to move to the position where the sheet metal is placed. After the suction cup device 8 absorbs the sheet metal, the robot arm 7 moves it above the lower mold 3. At this time, the first telescopic member 9 extends to push the sheet metal downward, thereby pressing the lifting block 4, so that the clamping part 61 of the lifting block 4 enters the clamping state, and the sheet metal is stably placed on the lower mold 3. Then, the stamping device 1 is started, and the upper mold 2 slides downward, and after contacting the sheet metal, it continues to press the lifting block 4 for a second time to ensure that the position of the sheet metal is stable during the stamping process.

[0060] The advantage is that, through the cooperation of the mechanical arm 7, the suction cup device 8 and the first telescopic member 9, the automatic loading of the sheet metal parts and the control of the lifting block 4 are realized, which greatly improves the production efficiency and reduces the time and labor intensity of manual operation. The mechanical arm 7 and the suction cup device 8 can accurately place the sheet metal parts on the lower mold 3, and the pressing of the first telescopic member 9 and the upper mold 2 on the lifting block 4 ensures the position accuracy of the sheet metal parts during the stamping process, thereby improving the stamping quality. This structure can adapt to sheet metal parts of different shapes and sizes, and improves the versatility and flexibility of the equipment.

[0061] Furthermore, the guide groove 41 has a first protrusion 414, and the first protrusion 414 has a guide surface 4141 and a first abutting surface 4142. The guide surface 4141 connects the slide-out section 413 and the first protrusion 414. After the clamping portion 61 slides over the first protrusion 414, it abuts against the first abutting surface 4142, so that the clamping portion 61 enters the slide-in section 411. The second swing rod 10 is also included. One end of the second swing rod 10 is hingedly arranged at the bottom of the installation groove 31. The first swing rod 10 is hingedly arranged at the bottom of the installation groove 31. One end of the rod 6 away from the clamping portion 61 is hingedly arranged at the bottom of the installation groove 31 through the other end of the second rocker arm 10. After the clamping portion 61 enters the slide-out section 413, it abuts against the guide surface 4141, so that the first rocker arm 6 swings. After the clamping portion 61 slides out of the slide-out section 413, the first rocker arm 6 is reset, and the clamping portion 61 abuts against the first abutting surface 4142; the second elastic member 11 is sleeved at the hinge between the first rocker arm 6 and the second rocker arm 10, and is used to provide force for resetting the first rocker arm 6.

[0062] In this embodiment, the guide groove 41 of the lifting block 4 has a first protrusion 414. The first protrusion 414 has a guide surface 4141 and a first abutting surface 4142, and the guide surface 4141 connects the slide-out section 413 and the first protrusion 414. When the clamping portion 61 slides over the first protrusion 414, it abuts against the first abutting surface 4142, so that the clamping portion 61 enters the slide-in section 411.

[0063] One end of the second swing rod 10 is hingedly arranged at the bottom of the installation groove 31, and one end of the first swing rod 6 away from the clamping portion 61 is hingedly arranged at the bottom of the installation groove 31 through the other end of the second swing rod 10. When the clamping portion 61 enters the slide-out section 413 and abuts against the guide surface 4141, the first swing rod 6 swings, and after the clamping portion 61 slides out of the slide-out section 413, the first swing rod 6 is reset, and at this time, the clamping portion 61 abuts against the first abutting surface 4142. The second elastic member 11 is sleeved at the hinge between the first swing rod 6 and the second swing rod 10, and is used to provide a force for the first swing rod 6 to reset.

[0064] For example, during the operation of the equipment, when the lifting block 4 is pressed so that the clamping portion 61 moves in the guide groove 41, the clamping portion 61 enters the slide-out section 413 and contacts the guide surface 4141 of the first protrusion 414, thereby driving the first swing arm 6 to swing. When the clamping portion 61 continues to move and slide out of the slide-out section 413, under the action of the second elastic member 11, the first swing arm 6 is reset, and the clamping portion 61 contacts the first contact surface 4142, preparing for the next action of the lifting block 4.

[0065] The advantage is that, through the design of the first protrusion 414, the guide surface 4141 and the first abutting surface 4142, and the cooperation of the first swing rod 6, the second swing rod 10 and the second elastic member 11, the moving path of the clamping portion 61 can be accurately controlled to ensure that the lifting block 4 is lifted and lowered in a predetermined manner, thereby improving the reliability of the equipment operation. The second elastic member 11 provides a reset force for the first swing rod 6, making the equipment more stable during operation and reducing the probability of failure caused by inaccurate position of the clamping portion 61.

[0066] Furthermore, it also includes a limit plate 12, which is used in pairs. One end of the limit plate 12 used in pairs is set at the bottom of the installation groove 31. The limit plate 12 is located on both sides of the hinge point between the second swing arm 10 and the bottom of the installation groove 31, and is used to limit the swing range of the second swing arm 10.

[0067] In this embodiment, the limiting plates 12 are used in pairs. One end of the pair of limiting plates 12 is disposed at the bottom of the installation slot 31 and is located at both sides of the hinge point between the second swing rod 10 and the bottom of the installation slot 31 .

[0068] During the operation of the equipment, when the first swing arm 6 and the second swing arm 10 are in motion, the limit plate 12 can limit the swing range of the second swing arm 10. Without the limit plate 12, the second swing arm 10 may swing excessively, causing the clamping portion 61 to be unable to move accurately in the guide groove 41, affecting the normal operation of the lifting block 4. With the limit plate 12, the swing of the second swing arm 10 is controlled within a certain range, ensuring that the clamping portion 61 can smoothly switch between the slide-in section 411, the clamping section 412 and the slide-out section 413.

[0069] The advantage is that the limit plate 12 can accurately limit the swing range of the second swing arm 10, ensuring that the moving path of the clamping portion 61 in the guide groove 41 is accurate, thereby ensuring that the lifting and lowering action of the jacking block 4 is stable and reliable. By limiting the swing of the second swing arm 10, the equipment failure that may be caused by excessive swinging is reduced, and the stability and reliability of the entire stamping equipment are improved. The existence of the limit plate 12 makes the equipment more convenient during debugging and maintenance. The swing range of the second swing arm 10 can be optimized by adjusting the position of the limit plate 12 to meet different work requirements.

[0070] Furthermore, the guide groove 41 , the first swing rod 6 , the second swing rod 10 and the second elastic member are combined to form a clamping device, and there are a plurality of clamping devices, which are evenly arranged on both sides of the lifting block 4 .

[0071] In this embodiment, the guide groove 41 , the first swing rod 6 , the second swing rod 10 and the second elastic member 11 are combined to form a clamping device. There are a plurality of clamping devices, which are evenly arranged on both sides of the lifting block 4 .

[0072] In actual equipment, two clamping devices may be provided on the left and right sides of the lifting block 4. These clamping devices work together during operation. When the lifting block 4 needs to be lowered, the clamping parts 61 of the first swing rod 6 in each clamping device simultaneously enter the clamping section 412 to ensure that the lifting block 4 is stably lowered. When the lifting block 4 needs to be raised, the clamping parts 61 in each clamping device synchronously slide out of the clamping section 412 and the slide-out section 413, and the lifting block 4 rises steadily under the action of the first elastic member 5.

[0073] The advantage is that multiple clamping devices are evenly distributed on both sides of the lifting block 4, so that the lifting block 4 is subjected to more uniform force during the lifting process, which improves the stability of the lifting block 4 and ensures the stability of the position of the sheet metal during the stamping process. If a single clamping device fails, the other clamping devices can still function, ensuring the overall reliability of the equipment and reducing the equipment downtime caused by the failure of a single component.

[0074] Furthermore, it also includes a limit rod 20, which is arranged in the installation groove 31 and is used to limit the lifting distance of the jacking block 4.

[0075] In this embodiment, the limiting rod 20 is disposed in the mounting groove 31. The length and position of the limiting rod 20 are precisely designed, and when the lifting block 4 rises or falls under the action of the first elastic member 5, the limiting rod 20 can limit the lifting distance of the lifting block 4.

[0076] In actual operation, when the lifting block 4 moves upward due to the elastic force of the first elastic member 5, the limit rod 20 can prevent the lifting block 4 from rising excessively, ensuring that the upper surface of the lifting block 4 and the upper surface of the lower mold 3 form a stamping surface at a suitable position. When the lifting block 4 is pressed downward by an external force, the limit rod 20 can prevent the lifting block 4 from falling too much and damaging the first elastic member 5 or affecting the normal operation of the equipment.

[0077] The advantage is that the limit rod 20 can accurately limit the lifting distance of the lifting block 4, ensuring that the lifting block 4 moves within a suitable range, thereby ensuring the accuracy and stability of the stamping process. By limiting the lifting distance of the lifting block 4, it is possible to prevent the lifting block 4 from excessively rising or falling and causing damage to the first elastic member 5 and other equipment components, thereby extending the service life of the equipment.

[0078] Furthermore, the stamping device 1 has a plurality of discharge troughs 101, which are located around the lower mold 3 and are used to collect waste. It also includes a toggle rod 13, and one end of the toggle rod 13 has a toggle portion 131. There are a plurality of toggle rods 13, and the other ends of the toggle rods 13 are all swingably set on the stamping device 1. The toggle rods 13 are arranged at intervals. After the toggle rod 13 swings, the toggle portion 131 is located above the discharge trough 101, and the toggle portion 131 is used to toggle the waste.

[0079] In this embodiment, the punching device 1 has a plurality of discharge grooves 101, which are located around the lower mold 3. A toggle rod 13 has a toggle portion 131 at one end, and the other ends of the plurality of toggle rods 13 are swingably disposed on the punching device 1, and the plurality of toggle rods 13 are disposed at intervals. When the toggle rod 13 swings, the toggle portion 131 is located above the discharge groove 101, and is used to toggle the waste material.

[0080] After the stamping process is completed, the waste material on the edge of the sheet metal part will fall into the discharge groove 101 around the lower mold 3. At this time, the operator can manually push the toggle rod 13 to swing it, so that the toggle part 131 enters the top of the discharge groove 101, and the waste material is pulled out of the discharge groove 101 for subsequent cleaning and recycling.

[0081] The advantage is that the design of the discharge trough 101 and the toggle rod 13 allows the waste to be concentrated in a specific area, and the waste can be cleaned up conveniently and quickly through the toggle action of the toggle rod 13, thereby improving the cleanliness and work efficiency of the production site. Timely cleaning of waste helps to recycle and reuse waste, reduce production costs, and improve resource utilization.

[0082] Furthermore, the toggle rod 13 has a second abutment surface 132. After the upper mold 2 slides downward, the upper mold 2 abuts against the second abutment surface 132, driving the toggle rod 13 to swing. It also includes a mounting rod 14. There are several mounting rods 14. The mounting rods 14 are set on the stamping device 1. Several toggle rods 13 are swingably set on the stamping device 1 through the mounting rods 14; the two ends of the third elastic member 15 are respectively hinged to the mounting rod 14 and the toggle rod 13, and are used to provide the toggle rod 13 with force to move the waste material after the upper mold 2 slides upward, so as to reset the toggle rod 13.

[0083] In this embodiment, the toggle rod 13 has a second abutting surface 132. After the upper mold 2 slides downward, the upper mold 2 abuts against the second abutting surface 132, driving the toggle rod 13 to swing. There are a plurality of mounting rods 14, which are arranged on the punching device 1, and a plurality of toggle rods 13 are swingably arranged on the punching device 1 through the mounting rods 14. The two ends of the third elastic member 15 are respectively hinged to the mounting rod 14 and the toggle rod 13. When the upper mold 2 slides upward, the third elastic member 15 provides the toggle rod 13 with a force to toggle the waste material, so that the toggle rod 13 is reset.

[0084] During the stamping operation, the upper die 2 moves downward to perform stamping and trimming. When it moves to a certain position, the upper die 2 contacts the second abutment surface 132 of the toggle rod 13, thereby pushing the toggle rod 13 to swing around the mounting rod 14. When the stamping is completed, the upper die 2 slides upward to withdraw. At this time, the elastic force generated by the contraction of the third elastic member 15 acts on the toggle rod 13, causing the toggle rod 13 to swing in the opposite direction and reset. During the reset process, the toggle portion 131 of the toggle rod 13 is located above the discharge trough 101, and the waste material is toggled for cleaning.

[0085] The advantage is that the movement of the upper mold 2 is linked with the action of the toggle rod 13, realizing the function of automatically cleaning the waste during the stamping process, without additional manual operation, and improving production efficiency. The toggle rod 13 is automatically reset by the third elastic member 15 to prepare for the next stamping and waste cleaning, ensuring the continuous operation of the equipment and reducing the downtime caused by waste accumulation. By using the movement of the upper mold 2 to drive the toggle rod 13 and the reset function of the third elastic member 15, the entire structure is simple in design, reliable in operation, and reduces the maintenance cost of the equipment.

[0086] Furthermore, it also includes a cutting knife 16 , and the number of the cutting knives 16 is several. The cutting knives 16 are arranged in the discharge trough 101 and are spaced apart from the toggle rod 13 .

[0087] In this embodiment, a plurality of cutting knives 16 are evenly distributed in the discharge trough 101 and are spaced apart from the toggle rod 13. When the stamping operation is performed, as the upper mold 2 is pressed downward, the waste material at the edge of the sheet metal part is cut off and contacts the cutting knives 16. The blades of these cutting knives 16 are sharp and strong, and can withstand the pressure and friction during the stamping process. During the cutting process, after the waste material is cut into small pieces, it is easier to be toggled by the subsequent toggle rod 13. When the toggle rod 13 swings, its toggle portion 131 is accurately located above the discharge trough 101, and the waste material cut into small pieces can be easily dialed into the discharge trough 101, so that the waste material can smoothly fall into the discharge trough 101 for collection and processing.

[0088] In actual production, when the punching device 1 is started, the upper die 2 moves downward to punch and trim the sheet metal part, and the waste material is cut off and cut into small pieces by the cutting knife 16. Then, the upper die 2 slides upward, and the toggle rod 13 pushed by the upper die 2 during the descent is reset under the action of the third elastic member 15, and the small pieces of waste material are pushed into the discharge chute 101.

[0089] The advantage is that the waste is cut into small pieces by the cutting knife 16 during stamping, which greatly optimizes the waste processing process. Small pieces of waste are not only easy to be moved by the toggle rod 13, but also more easily fall into the discharge trough 101, which improves the efficiency of waste cleaning. The cut small pieces of waste are not easy to block the discharge trough 101, which ensures the smoothness of discharge, ensures the continuous operation of the equipment, and reduces the downtime and maintenance cost caused by poor discharge.
