Description

Technical Field

[0001] The present invention relates to the technical field of bumper processing, and specifically to a forging device for automobile bumpers. Background Art

[0002] As a protective device for vehicles, automobile bumpers play a crucial role in the safety of pedestrians and the vehicle itself. It needs to have good strength and toughness to effectively absorb and disperse energy during a collision, protecting passengers and others from harm. The existing bumper production methods mainly include injection molding and die casting, etc., but there are certain limitations in terms of strength and precision, making it difficult to meet the increasingly strict safety standards and market demands.

[0003] Forging technology, with its unique forming ability and high material utilization rate, is widely used in the manufacture of various metal components, especially for components that require high precision and high strength characteristics. There is still room for improvement in the processing precision, forging efficiency, etc. of existing forging equipment and processes. Especially in the production process of large automobile bumpers, a forging device that can effectively improve the output rate and product quality is more needed.

[0004] When using forging technology to process bumpers made of metal materials, especially in the process of forging large automobile bumpers, due to the large volume of the material, it is difficult to move when feeding it into the forging equipment, resulting in low production efficiency and easy damage to the workpiece.

[0005] Therefore, the present invention proposes a forging device for automobile bumpers to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0006] In view of the above problems, the invention provides a forging device for automobile bumpers, which can effectively solve the problem that large bumpers are not easy to move in the existing technology. To achieve the above object, the embodiments of the present application provide the following technical solutions: The present invention discloses a forging device for automobile bumpers, including a base. A forging table is fixedly connected to the top of the base. A feeding mechanism for moving the forging plate above the forging table is arranged on the top of the base. A pressing mechanism for positioning the forging plate on the forging table is arranged above the forging table. A lifting mechanism for ejecting the forged plate is arranged at the bottom of the forging table. A servo mechanism for driving the feeding mechanism to move synchronously is arranged at the bottom of the base. A blowing mechanism for cleaning the residue of the forging plate is arranged inside the forging table; The feeding mechanism includes sliding rails symmetrically and fixedly connected to the upper surface of the base. Each sliding rail is externally and symmetrically slidably connected with a moving seat. A first sliding rod is fixedly connected between the two moving seats outside the same sliding rail. A supporting plate for holding the forging plate is symmetrically arranged between the two first sliding rods. At both ends of each supporting plate, sliders are symmetrically and fixedly connected. The sliders on the same side are slidably connected to the first sliding rod.

[0007] Furthermore, the feeding mechanism includes connecting rods rotatably connected to the tops of the sliders. At the ends of the two connecting rods on the same side away from the sliders, the same mounting seat is rotatably connected.

[0008] Furthermore, a guiding rod is fixedly connected to the bottom of the mounting seat. The bottom of the guiding rod slidably penetrates through the first sliding rod, and a first spring is slidably sleeved on the outside of the guiding rod. The first spring is located on the outside of the guiding rod between the first sliding rod and the mounting seat.

[0009] Furthermore, the pressing mechanism includes a bracket fixedly connected to the upper surface of the base. A hydraulic cylinder is fixedly connected to the top of the bracket. The output end of the hydraulic cylinder is fixedly connected with a forging hammer for extruding the forging plate.

[0010] Furthermore, sliding sleeves are symmetrically and fixedly connected to both sides of the forging hammer. An expansion rod is slidably connected in the cavity at the bottom of each sliding sleeve. The bottom of the expansion rod is fixedly connected with a first roller for pressing the forging plate against the forging table. The top of the expansion rod is fixedly connected with a second spring. One end of the second spring away from the expansion rod is fixedly connected to the top of the cavity of the sliding sleeve.

[0011] Furthermore, the jacking mechanism includes ejector rods symmetrically and vertically slidably connected inside the forging table. The bottom of each ejector rod slidably penetrates through the base, and the bottom of the ejector rod extends to the bottom of the base. An L-shaped plate is fixedly connected to the bottom of each ejector rod. A second roller is fixedly connected between the two L-shaped plates. A third spring is sleeved on the outside of each ejector rod, and the third spring is located on the outside of the ejector rod between the base and the L-shaped plate.

[0012] Furthermore, the jacking mechanism further includes a second sliding rod fixedly connected to the bottom of the base. A moving block is slidably connected to the outside of the second sliding rod. An inclined surface is provided at the top of the moving block, and the inclined surface is in rolling connection with the second roller.

[0013] Furthermore, a lead screw is threadedly connected to the bottom of the moving block. The two ends of the lead screw are rotatably connected to the bottom of the base. A motor is fixedly connected to the side of the base, and the output end of the motor is fixedly connected to one end of the lead screw.

[0014] Further, the servo mechanism includes notches symmetrically formed on the surface of the base. A vertical rod is slidably connected in each notch.

One end of the air delivery pipe away from the movable chamber is fixedly connected to an air storage tank, and the air storage tank is fixedly connected to the lower surface of the base.

[0016] Beneficial effects: 1. By setting up a feeding mechanism, the device conveys the plate to be forged to the bottom of the forging hammer by using two supporting plates. Then, the two supporting plates move away from each other to let the plate fall onto the forging die, which can smoothly transport the plate, avoid damages such as scratches and deformation that may be caused during manual operation, help maintain the quality of the material, and at the same time reduce direct manual intervention. Especially when dealing with large or heavy plates, it reduces the risk of worker injury.

[0017] 2. By setting up a pressing mechanism, before forging the plate, the first rollers that press down are used to fix the plate, avoiding the deviation of the plate during forging, ensuring that each forging is carried out at a predetermined position, thereby guaranteeing the dimensional accuracy and shape accuracy of the forged product. At the same time, since the plate is firmly fixed, there is no need to frequently adjust the position or worry about the deviation of the plate, which makes the entire forging process more smooth and efficient, and reduces the time loss of repeated operations.

[0018] 3. By setting up a jacking mechanism, after the forging is completed, when the forging hammer moves upward, it drives the ejector rod to move upward to jack up the forged product from the forging frame. The ejector rod actively pushes up the workpiece, which can quickly and effectively separate the forged product from the forging table. At the same time, the jacking mechanism can realize automatic discharging, reducing the labor intensity.

[0019] 4. By setting up a blowing mechanism, when the ejector rod jacks out the forged product, the movable block moves outward, so that the high-pressure air flow flows from the exhaust hole into the forging table. The high-pressure air flow blows out the residues in the forging table, and the high-pressure air flow automatically cleans the forging table, ensuring that the working surface is clean and free of foreign objects before each forging, avoiding problems such as forging defects or surface damage caused by residues being embedded in the next forging workpiece. At the same time, the blowing mechanism can complete the cleaning work synchronously after the ejection action is completed, without the need for additional shutdown operations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Refer to Figures 1 to 8 , a forging device for an automobile bumper in this embodiment includes a base 10. A forging table 70 is fixedly connected to the top of the base 10. A feeding mechanism 20 for moving a forging plate above the forging table 70 is arranged on the top of the base 10. A pressing mechanism 30 for positioning the forging plate on the forging table 70 is arranged above the forging table 70. A jacking mechanism 40 for ejecting the forged plate is arranged at the bottom of the forging table 70. A servo mechanism 50 for driving the feeding mechanism 20 to move synchronously is arranged at the bottom of the base 10. A blowing mechanism 60 for cleaning the residue of the forging plate is arranged inside the forging table 70.

[0033] The feeding mechanism 20 includes slide rails 201 symmetrically and fixedly connected to the upper surface of the base 10. A moving seat 202 is symmetrically and slidably connected to the outside of each slide rail 201. A first slide bar 203 is fixedly connected between the two moving seats 202 outside the same slide rail 201. A support plate 205 for holding the forging plate is symmetrically arranged between the two first slide bars 203. Sliders 204 are symmetrically and fixedly connected to both ends of each support plate 205. The sliders 204 on the same side are slidably connected to the first slide bar 203.

[0034] The feeding mechanism 20 further includes a connecting rod 206 rotatably connected to the top of the slider 204. The ends of the two connecting rods 206 on the same side away from the slider 204 are rotatably connected to the same mounting seat 207.

[0035] A guide rod 208 is fixedly connected to the bottom of the mounting seat 207. The bottom of the guide rod 208 slidably penetrates the first slide bar 203, and a first spring 209 is slidably sleeved on the outside of the guide rod 208. The first spring 209 is located on the outside of the guide rod 208 between the first slide bar 203 and the mounting seat 207.

[0036] During specific operation, the heated forging plate is placed on the surface of the two support plates 205, and the movable seat 202 is pushed horizontally to the top of the forging table 70 by the slide rail 201. Then, when the forging hammer 303 descends, the bottom of the forging hammer 303 collides with the bottom of the two mounting seats 207, and the descending forging hammer 303 pushes the mounting seat 207 and the guide rod 208 to slide downward along the first slide bar 203 synchronously. When the mounting seat 207 descends, it drives the two connecting rods 206 to push the slider 204 away from each other along the first slide bar 203, and the slider 204 synchronously drives the support plates 205 away from each other, so that the distance between the two support plates 205 becomes larger, and finally the forging plate placed on the two support plates 205 falls to the surface of the forging table 70.

[0037] After forging is completed, the forging hammer 303 moves upward. At this time, under the push of the elastic force of the first spring 209, the guide rod 208 and the mounting seat 207 move upward synchronously. The mounting seat 207 that moves upward drives the two sliders 204 on the same side to approach each other along the first slide rod 203 through the connecting rod 206, thereby driving the two support plates 205 to approach each other. Finally, the two support plates 205 are driven by the slide rail 201 to move to the outside of the forging table 70 to re-place the forged plate. The plate can be transported smoothly by using the support plate 205, avoiding scratches, deformation and other damages that may be caused during manual operation, which helps to maintain the quality of the material and reduce direct manual intervention, especially when handling large or heavy plates, reducing the risk of worker injury.

[0038] The pressing mechanism 30 includes a bracket 301 fixedly connected to the upper surface of the base 10 , a hydraulic cylinder 302 is fixedly connected to the top of the bracket 301 , and a forging hammer 303 for extruding forged plates is fixedly connected to the output end of the hydraulic cylinder 302 .

[0039] The forging hammer 303 is symmetrically fixedly connected with sliding sleeves 304 on both sides, and a telescopic rod 305 is slidably connected in the bottom cavity of each sliding sleeve 304. The bottom of the telescopic rod 305 is fixedly connected with a first roller 307 for squeezing the forged plate onto the forging table 70, and the top of the telescopic rod 305 is fixedly connected with a second spring 306. The end of the second spring 306 away from the telescopic rod 305 is fixedly connected to the top of the cavity of the sliding sleeve 304.

[0040] During specific operation, after the heated forging plate is conveyed above the forging table 70 by the feeding mechanism 20, the hydraulic cylinder 302 drives the forging hammer 303 to descend. When the forging hammer 303 descends, the forging plate first falls onto the forging table 70, and then the first roller 307 contacts the surface of the forging plate. When the forging hammer 303 continues to descend, the telescopic rod 305 slides inside the cavity of the sliding sleeve 304. Under the elastic force of the second spring 306, the first roller 307 is always pressed against the surface of the forging plate, preventing the plate from shifting during forging and ensuring that each forging is carried out at a predetermined position. This guarantees the dimensional accuracy and shape accuracy of the forged product. At the same time, since the plate is firmly fixed, there is no need to frequently adjust the position or worry about the plate shifting, making the entire forging process more smooth and efficient.

[0041] The lifting mechanism 40 includes ejector rods 401 symmetrically and vertically slidably connected inside the forging table 70. The bottom of each ejector rod 401 slidably penetrates through the base 10, and the bottom of the ejector rod 401 extends to the bottom of the base 10. A L-shaped plate 402 is fixedly connected to the bottom of each ejector rod 401, and a second roller 403 is fixedly connected between the two L-shaped plates 402. A third spring 409 is sleeved outside each ejector rod 401, and the third spring 409 is located outside the ejector rod 401 between the base 10 and the L-shaped plate 402.

[0042] The lifting mechanism 40 further includes a second sliding rod 406 fixedly connected to the bottom of the base 10. A moving block 404 is slidably connected to the outside of the second sliding rod 406. An inclined surface 405 is formed at the top of the moving block 404, and the inclined surface 405 is in rolling connection with the second roller 403.

[0043] The bottom of the moving block 404 is threadedly connected to a lead screw 407. The two ends of the lead screw 407 are rotatably connected to the bottom of the base 10. A motor 408 is fixedly connected to the side of the base 10, and the output end of the motor 408 is fixedly connected to one end of the lead screw 407.

[0044] During specific operation, the motor 408 drives the lead screw 407 to rotate. When the lead screw 407 rotates, it drives the moving block 404 to horizontally move along the second sliding rod 406. When the moving block 404 horizontally moves towards the motor 408, the inclined surface 405 of the moving block 404 pushes the second roller 403 to roll upward. During the upward rolling process of the second roller 403, the ejector rod 401 is driven to move upward through the L-shaped plate 402. When the ejector rod 401 moves upward, the forged plate in the forging table 70 is ejected, which can quickly and effectively separate the forged product from the forging table 70. At the same time, the lifting mechanism 40 can achieve automatic discharging, reducing the labor intensity.

[0045] After the forged plate is lifted, the screw rod 407 is driven to rotate in the reverse direction by the motor 408, so as to control the moving block 404 to move away from the motor 408. At this time, the second roller 403 rolls towards the lower part of the inclined surface 405, and the ejector rod 401 is pushed by the elastic force of the third spring 409, so that the ejector rod 401 descends to the bottom of the forging table 70.

[0046] The servo mechanism 50 includes notch openings 501 symmetrically formed on the surface of the base 10. A vertical rod 502 is slidably connected in each notch opening 501. One end of the vertical rod 502 is fixedly connected to the side surface of the moving seat 202, and the other end of the vertical rod 502 is fixedly connected to a cross rod 503. The end of the cross rod 503 away from the vertical rod 502 is fixedly connected to the side surface of the moving block 404. A push plate 504 is fixedly connected between the two moving blocks 404 away from the vertical rod 502.

[0047] During specific operation, when the moving block 404 moves horizontally towards the motor 408, the moving block 404 drives the moving seat 202 in the feeding mechanism 20 to move synchronously along the slide rail 201 towards the direction close to the motor 408 through the vertical rod 502 and the cross rod 503. When the moving seat 202 moves towards the direction close to the motor 408, the pallet 205 in the feeding mechanism 20 moves from above the forging table 70 to one side. At the same time, the push plate 504 horizontally pushes the lifted plate away from the forging table 70, so that the plate slides onto the surface of the base 10. Then, a new forged plate is placed on the pallet 205. Finally, the screw rod 407 is driven to rotate in the reverse direction by the motor 408, so as to control the moving block 404 to move away from the motor 408. The moving block 404 then drives the moving seat 202 in the feeding mechanism 20 to move synchronously along the slide rail 201 towards the direction away from the motor 408 through the vertical rod 502 and the cross rod 503, so as to convey the new forged plate above the forging table 70.

[0048] The blowing mechanism 60 includes a movable chamber 606 formed inside the ejector rod 401. Movable blocks 604 are symmetrically and slidably connected to the side surface of the movable chamber 606. An L-shaped exhaust hole 603 is formed inside each movable block 604. Each exhaust hole 603 communicates with the movable chamber 606, and a fourth spring 605 is fixedly connected between the two movable blocks 604. An air delivery pipe 602 is also fixedly connected inside the ejector rod 401, and the air delivery pipe 602 communicates with the movable chamber 606. One end of the air delivery pipe 602 away from the movable chamber 606 is fixedly connected to an air storage tank 601, and the air storage tank 601 is fixedly connected to the lower surface of the base 10.

[0049] During specific operation, when the ejector rod 401 ascends to eject the forged plate from the forging table 70, the two movable blocks 604 on the side of the ejector rod 401 move outwards synchronously. Under the elastic force of the fourth spring 605, the two movable blocks 604 move to the outside of the ejector rod 401. At this time, the exhaust hole 603 is communicated with the outside, and the high-pressure air flow in the air storage tank 601 enters the movable chamber 606 along the air delivery pipe 602 and is discharged into the forging table 70 from the exhaust hole 603. The high-pressure air flow flows from the exhaust hole 603 into the forging table 70, and the high-pressure air flow blows out the residues in the forging table 70. The high-pressure air flow automatically cleans the forging table 70, ensuring that the working surface is clean and free of foreign objects before each forging, and avoiding the problems of forging defects or surface damage caused by the residues being embedded in the next forging workpiece. At the same time, the blowing mechanism 60 can complete the cleaning work synchronously after the ejection action is completed, without the need for additional shutdown operations.

[0050] When the ejector rod 401 descends into the forging table 70, the two movable blocks 604 are squeezed by the through holes of the forging table 70, so that the two movable blocks 604 enter the inside of the ejector rod 401, and the exhaust hole 603 is blocked by the ejector rod 401. At this time, the high-pressure air flow will not be discharged to the outside.

[0051] Working principle: Place the plate to be forged into the feeding mechanism 20. The plate to be forged needs to be heated at a high temperature and then placed into the feeding mechanism 20. The feeding mechanism 20 moves the forged plate above the forging table 70, and then forges the plate through the pressing mechanism 30. During forging, the pressing mechanism 30 can also prevent the plate from shifting. After forging, the lifting mechanism 40 is used to lift the plate from the forging table 70. At the same time, the blowing mechanism 60 blows air into the forging table 70 to remove the residues. When the lifting mechanism 40 works, it drives the feeding mechanism 20 to move synchronously through the servo mechanism 50.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
