Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a forging device for automobile gear production. Background Art

[0002] At present, the automotive industry is booming, and gears are key components of automobiles, so the improvement of their manufacturing process is crucial. Traditional automotive gear production forging devices have many drawbacks and can no longer meet the needs of modern production.

[0003] In the past, forging equipment had insufficient protection against sparks generated when hammering steel billets. A large number of flying sparks not only endangered the personal safety of workshop workers, but also could damage peripheral equipment, leading to increased equipment maintenance costs and production interruptions. In the traditional forging process, the problem of mold heating is prominent. Frequent contact between the steel billet and the mold causes the mold temperature to rise rapidly, which not only reduces the strength of the mold itself and easily causes deformation, resulting in poor gear forming accuracy and unstable quality, but also makes it difficult to demold the steel billet at high temperature. The deformation problem during demolding causes the scrap rate to remain high.

[0004] It is difficult for traditional equipment to effectively clean the debris generated by forging. The debris accumulated on the die affects the placement accuracy of the steel billet. Mixing into the product will also cause quality defects, reduce product qualification rate, and increase production costs. The close fit between the steel billet and the die and the effects of thermal expansion and contraction make the traditional demolding method consume a lot of manpower and time. It may also damage the gear surface, affecting the product appearance and performance, further restricting the improvement of production efficiency and product quality.

[0038] The forging press 3 further includes an air curtain assembly 32, which includes a sealed cabin 321 fixedly connected to the interior of the forging press 3, the sealed cabin 321 fixed to the top of the inner cavity of the forging press 3 and located above the gear rod 315, a slide bar 322 fixedly connected to the top of the inner cavity of the forging press 3, a cover plate 323 slidably connected to the interior of the sealed cabin 321, the cover plate 323 slidably connected to the outer wall of the slide bar 322, a first fixedly connected between the upper surface of the cover plate 323 and the top of the inner cavity of the forging press 3 Second spring 324, the outer wall of the sealed cabin 321 is fixedly connected with a second air duct 325, the interior of the annular plate 311 is provided with an air outlet groove 326, the end of the second air duct 325 away from the sealed cabin 321 is fixedly connected to the interior of the air outlet groove 326 of the annular plate 311, the outer wall of the cover plate 323 is tightly fitted with the inner wall of the sealed cabin 321, the opening of the air outlet groove 326 is inclined toward the surrounding of the annular plate 311, and the bottom of the annular plate 311 is fitted with the upper surface of the base plate 1.

[0039] In actual use of the embodiment of the present invention: during forging, the worker places the steel billet on the template 4, and then starts the equipment to forge the steel billet. When the equipment is running, the forging press 3 hammers downward to shape the steel billet. The steel billet is formed under the hammering of the forging press 3 and the shaping action of the template 4. When the forging press 3 hammers the steel billet, the downward movement of the forging press 3 will drive the gear rod 315 to move downward together. Compared with the forging press 3, the gear rod 315 will first contact the upper surface of the bottom plate 1. When the forging press 3 continues to move downward, the gear rod 315 will slide relatively toward the inside of the forging press 3. When 315 slides toward the inside of the forging machine 3, the gear 313 drives the tooth plate 312 to slide downward. During the rotation of the gear 313, the torsion spring 314 generates torque due to twisting. The tooth plate 312 slides downward and drives the annular plate 311 to slide downward from the outer wall of the forging machine 3, and makes the bottom of the annular plate 311 fit tightly with the upper surface of the bottom plate 1, so as to prevent the sparks splashed by the steel billet when it is hit by the hammer from causing harm to the staff, thereby improving the safety of the equipment when in use. When the forging machine 3 is lifted upward, the torsion rebound of the torsion spring 314 drives the tooth rod 315 and the tooth plate 312 to engage and slide.

[0040] When the forging press 3 moves downward to prepare for hammering the steel billet, the gear rod 315 slides upward inside the forging press 3 to push the cover plate 323. During the sliding process of the cover plate 323 inside the sealed cabin 321, the space inside the sealed cabin 321 is squeezed to generate positive pressure. The positive pressure gas inside the sealed cabin 321 is blown toward the outer wall of the annular plate 311 through the second air guide pipe 325 and the air outlet groove 326. At this time, because the opening of the air outlet groove 326 is narrowed, the positive pressure gas inside the sealed cabin 321 cannot pass in time. The air outlet groove 326 discharges outward, so in the process of the forging machine 3 being lifted upward, the positive pressure gas inside the sealed cabin 321 will continue to be discharged outward through the air outlet groove 326. At this time, because the air outlet groove 326 is tilted outward inside the annular plate 311, the blown gas can form a conical wind curtain under the annular plate 311, which can effectively block the sparks generated during hammering. At the same time, the slag dropped on the bottom plate 1 can be cleared by high wind speed to prevent the slag from affecting the loading and unloading of the steel billet on the table.

[0041] See also Figures 1 to 6 A base plate 1 is provided below the forging machine 3, a template 4 is installed on the upper surface of the base plate 1 and directly below the forging machine 3, an electric telescopic rod 2 is installed on the upper surface of the base plate 1, a pushing assembly 21 is provided on the electric telescopic rod 2, and the pushing assembly 21 includes a U-shaped plate 211 fixedly connected to the output end of the electric telescopic rod 2, a motor 212 is slidably connected to the outer wall of the U-shaped plate 211, a round rod 213 is installed at the output end of the motor 212, a cone wheel 214 is fixedly connected to the outer wall of the round rod 213, the cone wheel 214 is located inside the U-shaped plate 211, a fan wheel 215 is fixedly connected to the outer wall of the round rod 213, and a first air duct 216 is sleeved on the outer wall of the fan wheel 215, an exhaust port 217 is opened inside the U-shaped plate 211, the first air duct 216 is connected to the exhaust port 217, and the inner cavity of the U-shaped plate 211 is fixedly connected with a shunt pipe 218.

[0042] The U-shaped plate 211 is slidably connected to the inside of the special-shaped plate 219, the top of the special-shaped plate 219 is rotatably connected to the gear shaft 2110, the bottom of the special-shaped plate 219 is rotatably connected to the cleaning brush 2111, a transmission belt 2112 is transmission-connected between the gear shaft 2110 and the cleaning brush 2111, both ends of the cleaning brush 2111 are rotatably connected to connecting rods 2113, one end of the connecting rod 2113 away from the cleaning brush 2111 is fixedly connected to a slider 2114, the slider 2114 is slidably connected to the inside of the U-shaped plate 211, and a first spring 2115 is fixedly connected between the lower surface of the slider 2114 and the bottom of the inner cavity of the U-shaped plate 211.

[0043] The cone wheel 214 slides toward one side of the special-shaped plate 219 and meshes with the special-shaped plate 219. The cone wheel 214 meshes with the gear shaft 2110. The opening of the exhaust port 217 located on the surface of the U-shaped plate 211 is tilted downward and narrowed. The outer wall of the special-shaped plate 219 close to the cone wheel 214 is symmetrically fixed with bevel teeth. The opening of the exhaust port 217 close to the template 4 is narrowed, and the opening of the exhaust port 217 is tilted toward the bottom of the U-shaped plate 211.

[0044] In actual use of the embodiment of the present invention: after the forging of the steel billet is completed, the electric telescopic rod 2 extends and pushes the U-shaped plate 211 to move in the direction close to the template 4. When the U-shaped plate 211 is fitted with the steel billet on the template 4, the round rod 213 is squeezed by the steel billet and slides in the direction close to the electric telescopic rod 2. At this time, the cone wheel 214 moving with the round rod 213 is engaged with the special-shaped plate 219. When the round rod 213 rotates, the special-shaped plate 219 is driven by the cone wheel 214 to slide downward inside the U-shaped plate 211. When the special-shaped plate 219 slides to the bottom, the cone wheel 214 is engaged with the special-shaped plate 219. The meshing slip forms a limit on the special-shaped plate 219, so that the special-shaped plate 219 drives the cleaning brush 2111 to be located below the U-shaped plate 211. At this time, the cone wheel 214 meshes with the gear shaft 2110 and drives the gear shaft 2110 to rotate. When the gear shaft 2110 rotates, it drives the cleaning brush 2111 to rotate together through the transmission belt 2112. Therefore, when the U-shaped plate 211 contacts the steel billet, the cleaning brush 2111 contacts the top of the template 4 and is in a rotating state, so that the debris scattered on the template 4 by the steel billet is swept away by the rotation of the cleaning brush 2111, thereby improving the stability of the steel billet when it is placed on the template 4.

[0045] When the motor 212 drives the round rod 213 to rotate, it also drives the impeller 215 to rotate. When the impeller 215 rotates, gas is injected into the first air duct 216. The gas is transmitted to the inside of the U-shaped plate 211 through the first air duct 216 and the diverter pipe 218, and then discharged through the exhaust port 217. The gas discharged from the exhaust port 217 will cool the contact position between the steel billet and the template 4, thereby preventing the steel billet from being easily deformed due to high temperature during demolding. At the same time, by cooling the top of the template 4, the strength of the template 4 during continuous forging can be ensured, thereby avoiding the problem of high temperature and easy deformation due to continuous hammering and pressure.

[0046] See also Figure 11 to Figure 12An auxiliary discharging assembly 41 is arranged below the template 4, and the auxiliary discharging assembly 41 includes a square rod 411 fixedly connected to the bottom of the output shaft of the electric telescopic rod 2, a limiting frame 412 is fixedly connected to the top of the bottom plate 1, a slide plate 413 is slidably connected inside the limiting frame 412, a third spring 414 is fixedly connected between the slide plate 413 and the side of the limiting frame 412 close to the electric telescopic rod 2, a push tube 415 is slidably connected inside the template 4, a slide 416 is slidably connected inside the push tube 415, a fourth spring 417 is fixedly connected between the top of the slide 416 and the top of the inner cavity of the push tube 415, and air outlet holes 418 are opened around the top of the push tube 415.

[0047] In actual use of the embodiment of the present invention: when the hammering of the steel billet is completed, the electric telescopic rod 2 is extended to prepare for demolding the steel billet and the template 4, the square rod 411 will push the slide plate 413 to slide inside the limit frame 412 to the side close to the template 4, and the third spring 414 is stretched and elastically stretched. When the slide plate 413 is close to the side of the slide 416 and contacts the slide 416, the slide plate 413 will push the slide 416 upward through its outer wall, so that the slide 416 slides upward inside the push tube 415 and the fourth spring 417 is squeezed and contracted. At this time, the push tube 415 is located inside the template 4, and the air outlet 418 is compressed. The inner wall of the template 4 is blocked and is in a closed state. The extrusion of the slide 416 inside the push tube 415 causes the interior of the push tube 415 to be in a positive pressure state. When the slide plate 413 continues to squeeze the bottom of the slide 416, the bottom of the slide 416 is completely fitted with the push tube 415. Therefore, the push tube 415 is lifted upward under the action of the slide plate 413. The upward lifting of the push tube 415 drives the steel billet to be lifted upward together. During the upward movement of the push tube 415, the air outlet 418 is no longer blocked by the inner wall of the template 4 and releases the positive pressure gas in the inner cavity of the push tube 415 to the outside, so that the contact surface between the steel billet and the template 4 is quickly cooled and separated, thereby improving the demolding efficiency.
