Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile bracket processing technology, and in particular to a stamping equipment with a buffer mechanism. Background Technology
[0002] Car brackets are automotive parts used to secure important components such as the engine and radiator, providing support and protection. In the automotive manufacturing process, especially in the manufacture of car brackets, stamping die processing technology plays a crucial role and is also a significant innovation in the automotive parts processing field, thus promoting the automotive manufacturing industry towards a more efficient, environmentally friendly, and intelligent direction.
[0003] In existing automotive bracket stamping equipment, the tight extrusion fit between dies often results in additional extrusion pressure. If these unnecessary pressures cannot be released or effectively relieved in time, they will accumulate continuously, placing a heavy pressure burden on the dies. Over time, this continuous pressure will not only shorten the service life of the dies, but may also cause the dies to deform or be damaged, thereby affecting the quality and precision of the stamped products.
[0004] Therefore, those skilled in the art have provided a stamping device with a buffer mechanism to solve the problems mentioned in the background art. Utility Model Content

First rotating blocks are rotatably installed at the lower ends of four moving blocks. Connecting blocks are rotatably installed between opposite sides of each pair of the four first rotating blocks.
[0008] An adjustment mechanism is provided inside the support base near the front end. The adjustment mechanism includes a screw. Two conveying pipes are fixedly provided inside the support base near the upper end. Multiple conveying ports are fixedly provided on opposite sides of the two conveying pipes.
[0009] Furthermore, each of the four movable blocks has a second rotating block rotatably mounted on its lower end, and each of the four second rotating blocks has a buffer block rotatably mounted on opposite sides of each other. The lower end of the support base is fixedly mounted with four sliding rods, and the four buffer blocks are slidably mounted on the outside of the four sliding rods. The lower end of each of the four buffer blocks is fixedly mounted with a second spring, and the lower end of each of the four second springs is fixedly mounted inside the lower end of the support base.
[0010] Furthermore, the lower mold base is externally slidably disposed inside the upper part of the support base, the lower end of the connecting block is fixedly disposed with a first spring, the lower end of the first spring is fixedly disposed inside the lower part of the support base, and the lower end of the trapezoidal block is slidably disposed on one side opposite to each of the four inclined blocks.
[0011] Furthermore, the two input ends of the delivery pipes are respectively fixedly installed on the upper ends of the two cylinders, and one-way valves are fixedly installed on opposite sides of the two cylinders. The opposite sides of the two one-way valves are respectively fixedly installed on opposite sides of the two oil storage tanks.
[0012] Furthermore, a worm gear is fixedly installed on the lower end of the screw, the lower end of the screw is rotatably installed inside the lower end of the support base, a worm is rotatably installed on the lower end of the support base near the rear end, the worm is externally meshed with the worm gear, and the connecting block is internally sleeved on the outside of the screw.
[0013] Furthermore, four fixing rods are fixedly installed at the lower end of the support base, and a slider is threadedly connected to the upper end of the screw. The slider is slidably installed outside the four fixing rods.
[0014] Furthermore, four compression springs are fixedly installed on the upper end of the support base, and each of the four compression springs is fitted with a guide rod. The lower ends of the four guide rods are fixedly installed on the upper end of the support base, and the upper ends of the four compression springs are fixedly installed on the lower end of the lower mold base.

[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model proposes a stamping equipment with a buffer mechanism. When the lower die base descends, the trapezoidal block moves accordingly and applies pressure to the inclined block, causing the inclined block to slide in the opposite direction within the support base. This causes the cylinder and damper to contract, and the moving block to move synchronously. The movement of the moving block causes the first rotating block and the second rotating block to rotate, which in turn causes the connecting block to slide upward along the outside of the screw and pull the first spring, causing it to deform. The rotation of the second rotating block pushes the buffer block to slide downward inside the support base. The buffer block slides along the outside of the slide rod and applies pressure to the second spring. Under the combined action of the buffer block, the damper, and the connecting block, the impact force between the upper die base and the lower die base is effectively absorbed and dispersed, thereby improving the overall stability and service life of the equipment.
[0018] 2. This utility model proposes a stamping equipment with a buffer mechanism. When stamping different models of car brackets, the worm gear is rotated to drive the worm wheel to rotate, which in turn causes the screw to rotate, causing the slider to slide along the fixed rod, thereby adjusting the buffer force. After the equipment completes the stamping, the trapezoidal block will release the pressure on the inclined block, causing the inclined blocks to move towards each other, which in turn causes the cylinder output end to extend, generating suction. The lubricating oil in the oil tank is drawn into the cylinder through the one-way valve, while preventing the lubricating oil from flowing back. The lubricating oil can reduce the wear between the trapezoidal block and the inclined block, thereby extending the service life of the equipment. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1-7 One embodiment provided by this utility model:
[0030] A stamping device with a buffer mechanism includes a base 5 and a lower die holder 9. A buffer structure 3 is provided on the upper end of the base 5. The buffer structure 3 includes a support 305, with oil reservoirs 7 fixedly mounted on both sides of the support 305. A trapezoidal block 302 is fixedly mounted on the lower end of the lower die holder 9. Dampers 307 are fixedly mounted on both the front and rear ends inside the support 305. Cylinders 306 are fixedly mounted on both sides inside the support 305. Inclined blocks 311 are fixedly mounted on the output ends of two cylinders 306 and two dampers 307. Moving blocks 312 are slidably mounted on the lower ends of the four inclined blocks 311. First rotating blocks 304 are rotatably mounted on the lower ends of the four moving blocks 312. Connecting blocks 301 are rotatably mounted between each pair of opposite sides of the four first rotating blocks 304. Each of the four moving blocks 312 has a second rotating block 308 rotatably mounted on its lower end. Each of the four second rotating blocks 308 has a buffer block 313 rotatably mounted on opposite sides of each other. Each of the four support bases 305 has four sliding rods 310 fixedly mounted on its lower end. Each of the four buffer blocks 313 has a second spring 309 fixedly mounted on its lower end. Each of the four second springs 309 has a lower end fixedly mounted on its lower end inside the support base 305. The lower mold base 9 has a lower end slidably mounted on its upper end inside the support base 305. Each of the four connecting blocks 301 has a first spring 303 fixedly mounted on its lower end. Each of the four first springs 303 has a lower end fixedly mounted on its lower end inside the support base 305. Each of the four trapezoidal blocks 302 has a lower end slidably mounted on opposite sides of each of the four inclined blocks 311.
[0031] Specifically, during operation, the upper mold base 2 drives the lower mold base 9 downward. As the lower mold base 9 descends, its lower trapezoidal block 302 moves synchronously, and its lower end gradually contacts and applies pressure to the inclined block 311, causing the inclined block 311 to slide in the opposite direction within the support base 305. The sliding of the inclined block 311 causes the cylinder 306 and damper 307 to contract. While the inclined block 311 is moving, it also drives the moving block 312 inside it to move synchronously. The displacement of the moving block 312 further causes the first rotating block 304 and the second rotating block 308 to rotate inside the support base 305. The rotation of the first rotating block 304 causes the connecting block 301 to rise and slide outside the screw 603, thereby stretching and deforming the first spring 303 connected to it. Meanwhile, the rotation of the second rotating block 308 pushes the buffer block 313 connected to it to slide down inside the support base 305. While the buffer block 313 slides outside the slide rod 310, it compresses the second spring 309 connected to it. Under the action of the buffer block 313, the damper 307 and the connecting block 301, the impact force between the upper mold base 2 and the lower mold base 9 will be absorbed and dispersed, thereby improving the stability and service life of the equipment.
[0032] Reference Figures 1-6 An adjustment mechanism 6 is provided inside the support base 305 near the front end. The adjustment mechanism 6 includes a screw 603. A worm gear 602 is fixedly provided on the lower end of the screw 603. The lower end of the screw 603 is rotatably provided inside the lower end of the support base 305. A worm gear 604 is rotatably provided on the lower end of the support base 305 near the rear end. The worm gear 604 is externally meshed with the worm gear 602. A connecting block 301 is internally sleeved on the outside of the screw 603. Four fixing rods 601 are fixedly provided inside the lower end of the support base 305. A slider 605 is threadedly connected to the upper end of the screw 603. The slider 605 is internally slidably provided on the outside of the four fixing rods 601.
[0033] Specifically, in the stamping process, for different models of car brackets, the worm gear 604 can be rotated to drive the worm wheel 602 to rotate, which in turn drives the screw 603 to rotate, causing the slider 605 to slide smoothly along the fixed rod 601, thereby achieving precise adjustment of the buffer force.
[0034] Reference Figures 2-7 Two conveying pipes 12 are fixedly installed inside the support base 305 near the upper end. The input ends of the two conveying pipes 12 are fixedly installed on the upper ends of the two cylinders 306 respectively. One-way valves 14 are fixedly installed on opposite sides of the two cylinders 306. The opposite sides of the two one-way valves 14 are fixedly installed on opposite sides of the two oil storage tanks 7 respectively. Multiple conveying ports 13 are fixedly installed on opposite sides of the two conveying pipes 12.
[0035] Specifically, when the inclined block 311 moves in opposite directions inside the support base 305, the cylinder 306 contracts and pressurizes the lubricating oil inside, which is then sprayed out through the delivery port 13 in the delivery pipe 12. The sprayed lubricating oil reduces the wear between the trapezoidal block 302 and the inclined block 311. After the stamping process is completed, the trapezoidal block 302 releases the pressure on the inclined block 311, causing the inclined blocks 311 to move closer to each other, resulting in the output end of the cylinder 306 extending outward and generating a suction effect. At this time, the one-way valve 14 plays a key role. It allows the lubricating oil in the oil reservoir 7 to be drawn into the cylinder 306, while effectively preventing the backflow of lubricating oil, thereby reducing the degree of wear during the buffering process.
[0036] Reference Figures 1-4 Four compression springs 10 are fixedly installed on the upper end of the support base 305. Guide rods 11 are sleeved inside each of the four compression springs 10. The lower ends of the four guide rods 11 are fixedly installed on the upper end of the support base 305. The upper ends of the four compression springs 10 are fixedly installed on the lower end of the lower mold base 9. Four connecting columns 4 are fixedly installed on the upper end of the base 5. A top plate 1 is fixedly installed on the upper end of the four connecting columns 4. Two hydraulic cylinders 8 are fixedly installed on the upper end of the top plate 1. The output ends of the two hydraulic cylinders 8 are fixedly installed on the upper mold base 2.
[0037] Specifically, when stamping the car bracket, the hydraulic cylinder 8 on the top plate 1 is activated, causing the upper die holder 2 to descend. When it moves to the set position, it will close with the lower die holder 9 and continue to move downward. The movement of the lower die holder 9 will compress the compression spring 10. The guide rod 11 will provide stable support and precise guidance for the lower die holder 9 and the upper die holder 2, ensuring the accuracy and stability of the stamping process, thereby realizing the stamping. The connecting column 4 connects the base 5 to the top plate 1.
[0038] Working principle: During use, the hydraulic cylinder 8 is activated to lower the upper mold base 2. When the upper mold base 2 moves to a certain position, it will close with the lower mold base 9, causing the lower mold base 9 to continue moving downward. This allows the interior of the upper mold base 2 to slide outside the guide rod 11, and the lower mold base 9 to compress the compression spring 10. When the lower mold base 9 slides downward inside the support base 305, it will drive the trapezoidal block 302 at its lower end to move synchronously. The movement of the trapezoidal block 302 will gradually contact the inclined block 311 and compress it, causing the inclined block 311 to slide in the opposite direction inside the support base 305. This, in turn, causes the cylinder 306 and the damper 307 to contract. When the cylinder 306 contracts, the lubricating oil inside will be squeezed and sprayed from the delivery port 13 in the output pipe onto the trapezoidal block. 302 externally, to reduce wear, at the same time, the movement of the inclined block 311 will synchronously drive the movement block 312 inside it to move. The movement of the movement block 312 will cause the first rotating block 304 and the second rotating block 308 to rotate. The rotation of the first rotating block 304 will pull the connecting block 301 to rise and slide outside the screw 603. The upward movement of the connecting block 301 will cause the first spring 303 connected to it to be pulled and deformed. The rotation of the second rotating block 308 will cause the buffer block 313 connected to it to slide downward inside the support seat 305. When the buffer block 313 moves, it will slide outside the slide rod 310 and squeeze the second spring 309 connected to it, causing it to contract inside the support seat 305, thereby relieving the impact of the upper mold seat 2 on the lower mold seat 9.
[0039] Secondly, when the stamping is completed, the hydraulic cylinder 8 drives the upper die holder 2 to move upward, causing the trapezoidal block 302 to release the pressure on the inclined block 311, resulting in the inclined blocks 311 moving towards each other. The movement of the inclined blocks 311 will cause the output end of the cylinder 306 to extend, thereby generating suction inside the cylinder 306. This allows the lubricating oil inside the oil reservoir 7 to enter the cylinder 306 through the one-way valve 14. The one-way valve 14 prevents the lubricating oil from flowing back into the reservoir when the cylinder 306 is pressing the lubricating oil inside. Inside the fuel tank 7, when stamping different models of car brackets, the cushioning force of the stamping is adjusted by the adjusting mechanism 6. First, by rotating the worm 604, the worm wheel 602 meshing with it rotates inside the support seat 305. Then, the worm wheel 602 drives the screw 603 to rotate inside the support seat 305. Since the slider 605 is threadedly connected to the screw 603, when the screw 603 rotates, the slider 605 will slide outside the fixed rod 601, thereby realizing the adjustment of the cushioning force.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
