Description

Technical Field

[0001] The utility model relates to the technical field of three-way catalytic converter processing equipment, in particular to a three-way catalytic converter shell shrinkage forming device. Background Art

[0002] Traditional three-way catalytic converter housing necking forming technology has numerous shortcomings, such as dents, corrugated warping, uneven transitions, and uneven end faces. These issues not only affect the product's aesthetics but also potentially reduce its catalytic efficiency and service life. Therefore, the industry urgently needs a necking forming device for three-way catalytic converter housings that can overcome these shortcomings and improve product availability. To meet this need, researchers conducted extensive technical research and development. They first analyzed the shortcomings of traditional necking forming technology and proposed various improvement solutions. Among them, a three-way catalytic converter housing necking forming device based on an inner eight-lobed die tensioning mechanism emerged as a promising candidate. This device utilizes an expanding core positioned at the center of the inner eight-lobed die. This core contacts the inclined surfaces of the die to support and tension the straight section of the inner wall of the housing port. Furthermore, the device incorporates components such as a cylinder block and piston rod. Driven by the cylinder, the cylinder applies uniform pressure to the housing end face, effectively addressing the dents, corrugated warping, and other issues inherent in traditional necking forming technology. Another device for shrinking the shell of a three-way catalytic converter also deserves attention. This device utilizes an outer mold plate, outer mold halves, a core rod, a shell, an inner mold halves, and a push rod. The outer mold halves' push rod applies a retaining force to the outer mold halves during the expansion process, effectively securing the shell end face. Furthermore, a guide post and a positioning plate are installed at the rear end of the push rod. A nitrogen spring propels the push rod, ensuring stable movement and ensuring natural shaping and uniform force distribution at the shell end. This device not only improves the quality of the shrinking process but also reduces the quality requirements for incoming shell material, thereby reducing production costs. With continuous technological advancement and innovation, the performance of three-way catalytic converter shell shrinking forming devices has also been significantly improved. Modern three-way catalytic converter shell shrinking forming devices now enable automated and intelligent production, significantly improving production efficiency and product quality. Furthermore, these devices offer high adaptability and flexibility, enabling rapid adjustment and optimization to meet diverse production needs.

[0003] According to Chinese patent number CN215614347U, a device for forming a three-way catalytic converter housing is disclosed. The device comprises a rectangular base plate, a drive housing disposed on one side of the upper surface of the rectangular base plate, a rotating shaft connected inwardly at the center of the inner side of the drive housing, a three-way catalytic converter to be formed by the forming process being fixed to the inner side of the rotating shaft via a clamping member, and two transverse slide rails disposed on the upper surface of the rectangular base plate at the lower end of the inner side of the drive housing. A horizontal movable seat is slidably mounted between the slide rails. A drive threaded rod passes through the interior of the horizontal movable seat and is driven to move horizontally left and right by the forward and reverse rotation of the drive threaded rod. A concave mounting seat is fixed to the upper surface of the horizontal movable seat. The device improves the quality of the three-way catalytic converter housing forming process, reducing phenomena such as concavity at the forming process, corrugated warping, uneven transition sections, and uneven end faces, thereby improving product availability.
