[0037] Embodiment 1:

[0038] Reference Figure 1-Figure 9 A forging device and process for deep rib parts of a car base crossbeam, comprising a pressure seat 1, a positioning rod 2 is fixedly connected to the side wall of the pressure seat 1, a mounting plate 21 is fixedly connected to the top of the positioning rod 2, a hydraulic cylinder 22 is fixedly connected to the top of the mounting plate 21, and also comprises: a forging block 3, the forging block 3 is fixedly connected to the bottom of the telescopic end of the hydraulic cylinder 22, wherein a forging die set is arranged between the bottom of the forging block 3 and the top of the pressure seat 1; a slag suction component, the slag suction component is arranged in the pressure seat 1, and the slag suction component is used for directionally collecting and processing the debris generated during the forging of the deep rib parts.

[0039] Reference Figure 1-Figure 3 , wherein the forging die set includes a bending die set 4, a pre-forging die set 41 and a final forging die set 42, and the bending die set 4, the pre-forging die set 41 and the final forging die set 42 are divided into an upper and a lower part, and the upper parts of the bending die set 4, the pre-forging die set 41 and the final forging die set 42 are fixed on the bottom of the forging block 3 in sequence, and the lower parts of the bending die set 4, the pre-forging die set 41 and the final forging die set 42 are fixed on the top of the pressure seat 1 in sequence, and the upper and lower parts of the bending die set 4, the pre-forging die set 41 and the final forging die set 42 are aligned with each other.

[0040] Through the arrangement of the above-mentioned structure, the blank to be forged is first placed on the lower bending die set 4, and then the hydraulic cylinder 22 is operated to drive the forging block 3 to fall rapidly, so that the forging blank is subjected to the first step of bending and forging at the bending die set 4; then the forging block 3 is lifted and reset, and the bent blank is transferred to the lower pre-forging die set 41, and then the forging block 3 falls again, so that the bent blank is subjected to the second step of pre-forging at the pre-forging die set 41; then the forging block 3 is lifted and reset again, and at this time the pre-forged blank is transferred to the lower final forging die set 42, and then the forging block 3 falls again, so that the pre-forged blank is subjected to the third step of final forging at the final forging die set 42, and finally a deep rib part of the beam is formed; in summary, the three-step split forging method is utilized, which is conducive to the stable and rapid forming of the deep rib part of the beam, reduces the forging difficulty, and improves the forging efficiency.

[0042] Reference Figure 7 , Figure 8 Among them, docking grooves 44 are opened at the corners around the lower parts of the pre-forging die set 41 and the final forging die set 42, and docking blocks 441 are fixedly connected at the corners around the upper parts of the pre-forging die set 41 and the final forging die set 42. The outer diameter of the docking block 441 is equal to the inner diameter of the docking groove 44, and the docking block 441 is aligned with the docking groove 44 up and down; the setting of the docking block 441 and the docking groove 44 can better help the upper and lower parts of the pre-forging die set 41 and the final forging die set 42 to be molded, effectively improving the forging accuracy.

[0043] Reference Figure 7 , Figure 8 Among them, both sides of the lower part of the pre-forging die set 41 are fixedly connected with resistance walls 45, and the resistance walls 45 are located on the surface of the lower part of the pre-forging die set 41. Such a setting can effectively reduce the gap between the upper and lower parts of the pre-forging die set 41, thereby improving the forging effect; both sides of the lower part of the final forging die set 42 are provided with U-shaped damping grooves 46; the setting of the U-shaped damping grooves 46 can make the upper and lower parts of the final forging die set 42 fit more closely when the film is closed, thereby effectively improving the forging quality.

[0044] Reference Figure 1-Figure 5 The slag suction component includes a slag dropping groove 5, which is opened on the top of the pressure seat 1, and the slag dropping groove 5 surrounds the outer side of the lower part of the bending die set 4, the pre-forging die set 41 and the final forging die set 42. A negative pressure groove 51 is opened in the pressure seat 1, and multiple groups of slag suction grooves 52 are opened between the negative pressure groove 51 and the slag dropping groove 5. A blocking plate 521 is fixedly connected to the output end of the negative pressure groove 51, and a negative pressure part that generates negative pressure suction in the negative pressure groove 51 is arranged in the forging block 3; the negative pressure part includes two groups of piston grooves 53, and the two groups of piston grooves 53 is opened on both sides of the forging block 3, and the rear piston plate 54 is slidably connected in the piston groove 53. The top of the piston plate 54 is fixedly connected with a push plate 541, and the push plate 541 passes through the piston groove 53 and extends to the top of the forging block 3. A return spring 55 is fixedly connected between the bottom of the piston plate 54 and the bottom of the inner cavity of the piston groove 53. Suction pipes 531 are fixedly connected on both sides of the piston groove 53. The two ends of the suction pipe 531 are respectively connected to the inner cavities of the piston groove 53 and the negative pressure groove 51, and a one-way valve is arranged in the suction pipe 531.

[0045] It should be noted that the one-way valve in the suction pipe 531 can only allow the gas in the negative pressure groove 51 to enter the piston groove 53 .

[0046] Through the arrangement of the above-mentioned structure, during the rapid falling of the forging block 3, under the rebound action of the reset spring 55, the piston plate 54 will quickly reset upwards, and at this time, negative pressure suction is generated in the cavity of the piston groove 53, and the one-way valve in the suction pipe 531 is opened, so that the negative pressure suction flows along the suction pipe 531 and enters the negative pressure groove 51, and finally suction is generated at the input port of each group of slag suction grooves 52, so that the airflow near the slag groove 5 moves into the negative pressure groove 51, so as to absorb the debris generated during the forging of the blank, so that the debris enters the negative pressure groove 51 and is collected, which effectively improves the cleanliness in the forging area, and at the same time avoids the adverse effect of excessive debris on forging, thereby ensuring the forging quality.

When the suction disappears, under the action of gravity, the filtered debris will fall to the bottom of the negative pressure tank 51 by itself, realizing the centralized collection of debris and ensuring the filtering effect of the filter screen 532; subsequently, it is only necessary to open the sealing plate 521 regularly to clean the collected debris.

[0048] Reference Figure 2 , Figure 4 and Figure 6 Among them, air outlet grooves 56 are opened on both sides of the forging block 3, and the air outlet groove 56 is connected to the inner cavity of the piston groove 53 through an air guide hole 561, and a one-way valve is arranged in the air guide hole 561.

[0049] It should be noted that the one-way valve in the air guide hole 561 can only allow the gas in the piston groove 53 to enter the air outlet groove 56 .

[0050] Through the arrangement of the above-mentioned structure, during the process of lifting and resetting the forging block 3, the mounting plate 21 will squeeze the push plate 541, so that the push plate 541 pushes the piston plate 54 to slide toward one side of the compression reset spring 55, and one side compresses the gas in the cavity of the piston groove 53, and opens the one-way valve in the air guide hole 561, so that the compressed airflow enters the air outlet groove 56 along the air guide hole 561, and finally blows toward the bending module 4, the pre-forging module 41 and the final forging module 42 through the blowing groove 562, thereby accelerating the gas flow rate in the area where the above three are located, improving the effective heat dissipation of the three, reducing hot stamping wear, and improving the durability of the bending module 4, the pre-forging module 41 and the final forging module 42.

[0051] Reference Figure 1-Figure 3 Among them, guide rods 6 are fixedly connected at the four corners of the pressure seat 1, the top of the guide rod 6 is fixedly connected to the bottom of the mounting plate 21, and the forging block 3 is slidably connected between the four groups of guide rods 6; the setting of the four guide rods 6 can ensure that the forging block 3 falls and rises stably along the guide rods 6, ensuring the forging accuracy, and also improving the stability of the forging impact.

[0052] Embodiment 2: A forging process for deep ribs of a car base cross beam is proposed, comprising the following steps:

[0053] Step 1: The blank is heated and roll forged;

[0054] Step 1: bending the roll-forged blank to form a bent blank;

[0055] Step 3: pre-forging the bent blank in step 2 to form a pre-forged blank;

[0056] Step 4: final forging the pre-forged blank to form a primary product;

[0057] Step 5: Trim the initial product after final forging to form deep ribs of the beam.

[0058] Reference Figure 1-Figure 9 In the present invention, when in use, the blank to be forged is first placed on the lower bending die set 4, and then the hydraulic cylinder 22 is operated to drive the forging block 3 to fall rapidly, so that the forging blank is subjected to the first step of bending and forging at the bending die set 4; then the forging block 3 is lifted and reset, and the bent blank is transferred to the lower pre-forging die set 41, and then the forging block 3 falls again, so that the bent blank is subjected to the second step of pre-forging at the pre-forging die set 41; then the forging block 3 is lifted and reset again, and at this time the pre-forged blank is transferred to the lower final forging die set 42, and then the forging block 3 falls again, so that the pre-forged blank is subjected to the third step of final forging at the final forging die set 42, and finally a crossbeam deep rib part is formed; in summary, the three-step split forging method is used to facilitate the stable and rapid forming of the crossbeam deep rib part, reduce the forging difficulty, and improve the forging efficiency.

[0059] During the process of lifting and resetting the forging block 3, the mounting plate 21 will squeeze the push plate 541, so that the push plate 541 pushes the piston plate 54 to slide toward one side of the compression reset spring 55, compressing the gas in the cavity of the piston groove 53 on one side, and opening the one-way valve in the air guide hole 561, so that the compressed airflow enters the air outlet groove 56 along the air guide hole 561, and finally blows toward the bending module 4, the pre-forging module 41 and the final forging module 42 through the blowing groove 562, thereby accelerating the gas flow rate in the area where the above three are located, improving the effective heat dissipation of the three, reducing hot stamping wear, and improving the durability of the bending module 4, the pre-forging module 41 and the final forging module 42. During the rapid falling of the forging block 3, under the rebound action of the reset spring 55, the piston plate 54 will quickly reset upwards, and at this time, negative pressure suction is generated in the cavity of the piston groove 53, and the one-way valve in the suction pipe 531 is opened, so that the negative pressure suction flows along the suction pipe 531 and enters the negative pressure groove 51, and finally suction is generated at the input port of each group of slag suction grooves 52, so that the airflow near the slag groove 5 moves into the negative pressure groove 51, so as to absorb the debris generated during the forging of the blank, so that the debris enters the negative pressure groove 51 and is collected, which effectively improves the cleanliness in the forging area, and at the same time avoids the adverse effect of excessive debris on forging, thereby ensuring the forging quality.
