[0002] The automobile support reinforcing plate is not an independent part, but a functional part or reinforcing part, which is usually attached to the key support or mounting point of the main body structure, chassis or suspension system of the vehicle body through welding, riveting or bonding. It is installed in the area with concentrated stress to improve the rigidity and strength, and increase the local rigidity to change the natural frequency of the structure, so as to avoid resonance with engine or road excitation, thereby reducing noise, vibration and unevenness, improving ride comfort. The automobile will withstand millions of vibrations and impacts in its life cycle. The reinforcing plate effectively prevents cracks in the base material due to fatigue by dispersing stress and reducing peak stress, thereby prolonging the service life of the vehicle body structure.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figure 1 - Figure 2 As shown, a mold for forming a car bracket reinforcement plate includes an upper mold assembly 1 and a lower mold assembly 2. The upper mold assembly 1 is slidably connected to the top of the lower mold assembly 2. The lower mold assembly 2 is fixedly set on the bottom surface. A material turning mechanism 3 is provided on the lower mold assembly 2. A first pushing inclined block 4 is provided on the rear side of the lower mold assembly 2. A second pushing inclined block 5 is provided on the front side of the lower mold assembly 2. A conveyor belt 6 is provided below the lower mold assembly 2. The upper mold assembly 1 can slide vertically on top of the lower mold assembly 2 to drive the flipping mechanism 3 to flip. The upper mold assembly 1 can drive the first pusher sloping block 4 to slide horizontally by sliding vertically on top of the lower mold assembly 2. The upper mold assembly 1 can slide vertically on top of the lower mold assembly 2, which can drive the second pusher block 5 to slide horizontally.

[0030] In this embodiment, the sheet metal enters between the upper mold assembly 1 and the lower mold assembly 2 through the sides. The upper mold assembly 1 presses down to stamp the sheet metal into shape. Then, the upper mold assembly 1 rises away from the lower mold assembly 2, and the ejector pin on the lower mold assembly 2 pushes the formed car bracket reinforcement plate out of the mold. At the same time, the rise of the upper mold assembly 1 drives the flipping mechanism 3 to flip, lifting the formed car bracket reinforcement plate and flipping it to the front of the lower mold assembly 2. During this process, the rise of the upper mold assembly 1 synchronously drives the first pushing slant block 4 and the second pushing slant block 5 to assist the flipping mechanism 3 in pushing the formed car bracket reinforcement plate into the conveyor belt 6, completing the unloading of the formed car bracket reinforcement plate, realizing automated unloading, reducing the risk of manual intervention, reducing the labor intensity of operators, improving production efficiency, and ensuring operational safety. After one operation is completed, the flipping mechanism 3 and the first pushing slant block 4 and the second pushing slant block 5 are reset when the upper mold assembly 1 presses down, preparing for the next stamping, ensuring that the entire forming and unloading process is continuous and efficient.

[0031] like Figure 1 - Figure 3 As shown, the upper mold assembly 1 includes a movable mold 11, an upper backing plate 12, and a pressure plate 13. The lower mold assembly 2 includes a fixed mold 21 and a lower backing plate 22. The fixed mold 21 is fixedly connected to the top of the lower backing plate 22. Guide rods 221 are symmetrically fixedly connected to the four corners of the lower backing plate 22. The movable mold 11 is fixedly connected to the bottom of the upper backing plate 12. The pressure plate 13 is slidably connected to the bottom of the movable mold 11. The guide rods 221 pass through the upper backing plate 12. The upper backing plate 12 is slidably connected to the guide rods 221. A fixing plate is fixedly connected to the top of the guide rods 221. A hydraulic punch is fixedly installed on the fixing plate. The bottom of the hydraulic punch is fixedly connected to the top of the upper backing plate 12.

[0032] In this embodiment, the hydraulic punch drives the upper pad 12 to descend steadily along the guide rod 221, causing the moving die 11 and the pressure plate 13 to press down synchronously. The pressure plate 13 contacts the sheet metal and presses it down before the moving die 11. Then the moving die 11 continues to descend and cooperates with the fixed die 21 to complete the stamping process, ensuring that the sheet metal remains stable during the stamping process, avoiding displacement or deformation, and improving the forming accuracy. At the same time, the pressure plate 13 can achieve buffering and pressing under the elastic action of the spring, effectively absorbing the impact force of the stamping moment, reducing die wear, and extending the service life of the equipment.

[0033] like Figure 4 -Figure 7 As shown, the flipping mechanism 3 includes a flipping plate 31, a hinge seat 32, a flipping rod 33, and a return spring 34. The front side of the flipping plate 31 is hinged to the front side of the fixed mold 21, the hinge seat 32 is slidably connected to the rear side of the flipping plate 31, the top of the flipping rod 33 is rotatably connected to the hinge seat 32, and the return spring 34 is sleeved on the flipping rod 33. The bottom of the flipping rod 33 passes through the rear side of the lower pad 22, and the flipping rod 33 is slidably connected to the lower pad 22. The top of the return spring 34 is fixedly connected to the bottom of the lower pad 22, and the bottom of the return spring 34 is fixedly connected to the flipping rod 33. A connecting rod is fixedly connected to the rear side of the flipping rod 33, and the top of the connecting rod is fixedly connected to the upper pad 12.

[0034] In this embodiment, when the upper pad plate 12 completes the stamping return stroke and moves upward, the reset spring 34 releases energy to push the flipping rod 33 to move upward, which drives the hinge seat 32 to move upward, and then pulls the flipping plate 31 to rotate upward around the front hinge point, so as to smoothly lift and flip the formed car bracket reinforcing plate out of the material. When the upper pad 12 moves downward, it drives the tilting rod 33 to move downward synchronously, compressing the return spring 34 to store energy. The vertical descent of the tilting rod 33 can drive the tilting plate 31 to automatically reset after the material is discharged, keeping it in contact with the fixed mold 21, preparing for the next stamping operation and ensuring a continuous and stable production process.

[0035] like Figure 8 - Figure 11 As shown, a first slide rail 222 is fixedly installed on the rear side of the lower pad 22. A first pusher block 4 is slidably connected to the first slide rail 222. A first push rod 41 is fixedly connected to the front end of the first pusher block 4. A first slide rod 42 is fixedly connected to the rear end of the first pusher block 4. A first vertical plate is fixedly connected to the rear side of the first slide rail 222. The first slide rod 42 passes through the first vertical plate and is slidably connected to the first vertical plate. A first spring 2221 is sleeved on the first slide rod 42. One end of the first spring 2221 is fixedly connected to the first vertical plate, and the other end of the first spring 2221 is fixedly connected to the first slide rod 42. A first pressure rod 121 is fixedly connected to the rear side of the upper pad 12. A first roller is rotatably connected to the bottom of the first pressure rod 121. The first roller is in contact with the top inclined surface of the first pusher block 4. A second slide rail 223 is fixedly installed on the front side of the lower pad 22. The second pusher block 5 is slidably connected to the second slide rail 223. A second push rod 51 is fixedly connected to the rear end of the second pusher block 5. A second slide rod 52 is fixedly connected to the front end of the second pusher block 5. A second vertical plate is fixedly connected to the front side of the second slide rail 223. The second slide rod 52 passes through the second vertical plate and is slidably connected to the second vertical plate. A second spring 2231 is sleeved on the second slide rod 52. One end of the second spring 2231 is fixedly connected to the second vertical plate. The other end of the second spring 2231 is fixedly connected to the second slide rod 52. A second pressure rod 122 is fixedly connected to the front side of the upper pad plate 12. A second roller is rotatably connected to the bottom of the second pressure rod 122. The second roller is in contact with the top inclined surface of the second pusher block 5.

[0036] In this embodiment, when the upper pad 12 moves downward, the first roller rolls along the inclined surface of the first pushing inclined block 4, forcing the first pushing inclined block 4 to move horizontally backward along the first slide rail 222, compressing the first spring 2221 to store energy. When the upper pad 12 moves upward on the return trip, the pressure on the first pushing inclined block 4 is released, and the first spring 2221 releases its stored energy to push the first pushing inclined block 4 to slide horizontally forward. At the same time, when the upper pad 12 moves downward, the second roller rolls along the inclined surface of the second pusher block 5, forcing the second pusher block 5 to move forward horizontally along the second slide rail 223, compressing the second spring 2231 to store energy. When the upper pad 12 moves upward on the return trip, the pressure on the second pusher block 5 is released, and the second spring 2231 releases its stored energy to push the second pusher block 5 to slide backward horizontally. After stamping, when the upper pad 12 moves upward, the formed car bracket reinforcing plate is smoothly lifted and flipped by the flipping plate 31. The first pusher 4 moves forward under the push of the first spring 2221, and the first push rod 41 pushes the rear side of the flipped formed car bracket reinforcing plate, assisting the formed car bracket reinforcing plate to move forward. The second pusher 5 moves backward under the action of the second spring 2231, and the second push rod 51 pushes the front side of the flipped formed car bracket reinforcing plate, assisting the formed car bracket reinforcing plate to flip 90 degrees and fall towards the conveyor belt 6.

[0037] like Figure 8 - Figure 12 As shown, a material feeding ramp 224 is fixedly provided on the front side of the lower pad 22, and a material limiting frame 225 is fixedly provided on the front side of the material feeding ramp 224. The second push rod 51 passes through the front side wall of the material limiting frame 225 and is slidably connected to the material limiting frame 225. A material collection frame 61 is placed on the conveyor belt 6, and the material collection frame 61 is located below the material limiting frame 225.

[0038] In this embodiment, the flipping plate 31 rotates upward around the front hinge point to smoothly lift and flip the formed car bracket reinforcement plate for discharge. The car bracket reinforcement plate enters the limiting frame 225 through the discharge ramp 224. After the second push rod 51 slides backward into the limiting frame 225, it can push the front end of the car bracket reinforcement plate in the limiting frame 225, so that the car bracket reinforcement plate in the limiting frame 225 completes a 90-degree flip. Then it slides vertically from the limiting frame 225 to the conveyor belt 6. After the car bracket reinforcement plate slides vertically from the limiting frame 225, it can fall accurately into the collection frame 61. The conveyor belt 6 advances intermittently periodically. Every time the upper pad plate 12 completes one stamping cycle, the conveyor belt 6 advances the distance of one station, so that the formed car bracket reinforcement plates are stacked vertically in an orderly manner in the collection frame 61, which facilitates the subsequent transportation and processing of the formed car bracket reinforcement plates.

[0039] Working principle: During operation, the sheet metal enters between the upper mold assembly 1 and the lower mold assembly 2 through the side of the upper mold assembly 1 and the lower mold assembly 2. The hydraulic punch drives the upper pad plate 12 to descend steadily along the guide rod 221, which drives the moving mold 11 and the pressure plate 13 to press down synchronously. The pressure plate 13 contacts the sheet metal and presses it down before the moving mold 11. Then the moving mold 11 continues to descend and cooperates with the fixed mold 21 to complete the stamping. During this process, when the upper pad plate 12 moves downward, it drives the flipping rod 33 to move downward synchronously, compressing the reset spring 34 to store energy. The vertical descent of the flipping rod 33 can drive the flipping plate 31 to automatically reset after the material is discharged, keeping it in contact with the fixed mold 21. At the same time, the first roller rolls along the inclined surface of the first pusher block 4, forcing the first pusher block 4 to move horizontally backward along the first slide rail 222, compressing the first spring 2221 to store energy; the second roller rolls along the inclined surface of the second pusher block 5, forcing the second pusher block 5 to move horizontally forward along the second slide rail 223, compressing the second spring 2231 to store energy. When the upper pad 12 completes the stamping return stroke and moves upward, the reset spring 34 releases energy to push the flipping rod 33 to move upward, which in turn drives the hinge seat 32 to move upward, thereby pulling the flipping plate 31 to rotate upward around the front hinge point, so as to smoothly lift and flip the formed car bracket reinforcing plate for discharge. At the same time, the first pressure rod 121 releases the pressure on the first pusher block 4, the first spring 2221 releases its stored energy to push the first pusher block 4 to slide forward horizontally, and the first push rod 41 pushes the rear side of the flipped-over molded car bracket reinforcing plate to assist the molded car bracket reinforcing plate to move forward. Then, the car bracket reinforcing plate enters the limiting frame 225 through the feeding ramp 224. The second pressure rod 122 releases the pressure on the second pushing ramp 5. The second spring 2231 releases its stored energy and pushes the second pushing ramp 5 to slide horizontally backward. After the second push rod 51 slides backward into the limiting frame 225, it can push the front end of the car bracket reinforcing plate in the limiting frame 225, so that the car bracket reinforcing plate in the limiting frame 225 can complete the rotation of 90 degrees. Then, it slides vertically from the limiting frame 225 to the conveyor belt 6. After the car bracket reinforcing plate slides vertically from the limiting frame 225, it can fall accurately into the collecting frame 61. Repeat the above steps. Each time the upper pad 12 is raised and lowered, one stamping cycle is completed. The conveyor belt 6 advances intermittently. Each time the upper pad 12 completes one stamping cycle, the conveyor belt 6 advances one station distance, so that the formed car bracket reinforcing plates are stacked vertically in an orderly manner in the material collection frame 61, which facilitates the subsequent transportation and processing of the formed car bracket reinforcing plates.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
