Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a KAB safety airbag housing cover plate bending machine. Background Art

[0002] In the field of automobile airbag production, there are a series of technical problems that need to be solved in the assembly process of KAB airbag housing and cover. These problems limit production efficiency, product quality and cost control. Traditional assembly equipment is often designed for a single product and lacks specialized parts that can be quickly replaced, making it difficult to adapt to the assembly needs of a variety of KAB airbags. Once the product model changes, the company may need to repurchase or modify the equipment, which not only costs a lot of money, but also causes production stagnation, affecting production progress and corporate benefits.

[0003] Some assembly equipment was designed without fully considering the operator's work convenience. For example, the height area for picking and placing parts was set unreasonably, and the operating space was narrow, which required workers to frequently bend, turn around, or perform unnatural movements when frequently picking and placing KAB airbag workpieces. This increased the workers' labor intensity, and long-term operation could easily cause physical fatigue and occupational diseases, while also reducing production efficiency.

[0004] During the assembly process of the KAB airbag housing and cover plate, strict requirements are placed on the bending operation of the housing. It is difficult for traditional equipment to accurately control the point and size of the bending force during bending, which can easily cause unnecessary pressure on parts of the housing other than the bending point, thereby causing deformation of the housing. The deformation of the housing may affect the normal ejection of the airbag, reduce product safety, and increase safety hazards. Therefore, a KAB airbag housing cover plate bending machine is proposed to solve the above-mentioned problems. Summary of the invention

[0030] A support part 4 is provided on the main seat plate assembly 1, and the support part 4 includes four linear bearings 41.

[0031] It is worth mentioning that a shell part 7 is provided on the tooling part 3, and the shell part 7 includes an airbag assembly shell 71. The airbag assembly shell 71 is installed on the positioning tooling base 31, and the outer wall of the airbag assembly shell 71 is integrally provided with a supporting positioning surface 72, and one side of the shell opening of the airbag assembly shell 71 is integrally connected with a slanted side U-shaped flange 73, and the other side of the shell opening of the airbag assembly shell 71 is integrally connected with a straight side U-shaped flange 76, the slanted side U-shaped flange 73 is provided with a number of plug-in grooves 74 corresponding to the bending head 514, and the outer wall surface of each plug-in groove 74 is provided with a bending surface 75 aligned with the bending head 514, and the straight side U-shaped flange 76 is provided with a number of plug-in grooves 2 corresponding to the elbow replacement part 63, and the outer wall surface of each plug-in groove 2 is provided with a bending surface 2 aligned with the elbow replacement part 63.

[0032] A cover portion 8 is provided on the outer shell portion 7, and the cover portion 8 includes an airbag assembly cover 81. The bottom sides of the airbag assembly cover 81 are respectively connected with wedge-shaped pins 82 corresponding to the number of plug-in slots 1 74 and 2, each wedge-shaped pin 82 is respectively plugged into the corresponding plug-in slot 1 74 and the inner wall of the plug-in slot, and an airbag tear line 83 is provided in the middle of the airbag assembly cover 81.

[0033] Working principle: place the shell of the KAB airbag on the airbag assembly shell 71 of the tooling part 3, use the positioning tooling base 31 for preliminary positioning, start the closing and clamping cylinder 25, and its movable end pushes the closing and clamping plate 26 to move downward along the linear guide pair 22. The clamping adjustment column 27 at the bottom of the closing and clamping plate 26 cooperates with the closing adjustment bolts 32 at the top of the two ends of the positioning tooling base 31 to further adjust the clamping force and position of the workpiece to ensure the relative position of the shell and the cover plate during the closing process. At the same time, the tooling track wheel 35 descends synchronously with the positioning tooling base 31.

[0034] For the narrow side, during the downward movement of the closing and clamping plate 26, the tooling track wheel 35 contacts the curved guide plate 59 of the narrow side bending portion 5 and slides along its surface. As the tooling track wheel 35 rolls, the curved guide plate 59 slides in the guide hole of the L-shaped front support 57 through the guide bolt 510. At the same time, the height locking bolt 58 can adjust and lock the height of the curved guide plate 59 to meet the needs of different products. The outer wall of the airbag assembly shell 71 squeezes the bending support 511, and the support seat plate 56 slides along the lower guide rail pair 516 and the upper guide rail pair 517 through the supporting slide plate 518. In this process, the compensation spring 521 plays a role of buffering and fine-tuning to ensure that the bending support 511 is inserted into the inner side of the support positioning surface 72 of the adaptive airbag assembly shell 71 into the U-shaped flange 73 on the oblique side.

[0035] For the straight-mouth side, the straight-mouth side bending replacement part 6 can directly replace the corresponding parts through installation and disassembly, and is used to adapt to the straight-mouth side U-shaped flange 76 of the airbag assembly shell 71, and there is no need to install the curved guide plate 59 on the L-shaped support replacement part 66 on this side. Since the straight-mouth side U-shaped flange 76 opens vertically downward, when the shell moves downward as a whole with the closing action, the bending support replacement part 65 of the straight-mouth side bending replacement part 6 can be directly inserted into the inner side of the U-shaped mouth, and staggeredly fit the inner side surface of the support positioning surface 72 to form a support limiting effect. Other components of the straight-mouth side bending replacement part 6, such as the push plate replacement part 61, the elbow seat replacement part 62, the elbow replacement part 63, the support seat replacement part 64 and the L-shaped support replacement part 66, work in coordination with the corresponding components of the narrow-mouth side bending part 5 to ensure the smooth progress of the straight-mouth side bending operation.

[0036] When the bending support member 511 and the bending support replacement member 65 reach the inner side of the supporting surfaces on both sides of the shell respectively and fit together, the lifting spring 47 of the support part 4 is in a compressed state, providing power for the subsequent rise of the positioning tooling, and the main cylinder 54 is started. The piston rod of the main cylinder 54 pushes the bending push plate 515 through the cylinder piston rod joint 512. The bending push plate 515 drives the elbow seat plate 513 and the bending head 514 to move toward the bending surface 1 75 of the shell. At the same time, the elbow replacement member 63 on the straight mouth side also moves toward the bending surface 2 on the straight mouth side under the action of the corresponding driving mechanism. During the bending process, the displacement sensor 55 monitors the positions of the bending head 514 and the elbow replacement member 63 in real time to accurately control the bending amount. The bending support member 511 and the bending support replacement member 65 are subjected to reaction force during the bending process, so that the bending force only acts on each other through the outer side of the U-shaped flange, avoiding unnecessary pressure on the part of the shell other than the bending part, thereby ensuring that the shell is not deformed.

[0037] When the bending head 514 and the elbow replacement part 63 bend the outer bending surface 1 75 and the bending surface 2 of the plug-in slot 1 74 and the plug-in slot 2, the bending part tightly presses the corresponding wedge-shaped pin 82. After the assembly is completed, the main cylinder 54 and the closing cover clamping cylinder 25 retract, and under the action of the compensation spring 521 and the lifting spring 47, the support seat plate 56 and the positioning tool base 31 return to their initial positions respectively, the bending support part 511 and the bending support replacement part 65 are separated from the airbag assembly shell 71, and the closing cover clamping plate 26 rises. At this time, the KAB airbag shell cover plate assembly that has completed the bending assembly can be taken out, completing a working cycle.
