Embodiment Construction
[0025] The present invention will be described in detail below with reference to the drawings and embodiments.
[0026] A method for forming a filter flange by flushing and rotating integrally includes the following steps:
[0027] 1) Reference figure 1 with figure 2 , Punching blanks: using a circular sheet material 100, punch out the center hole and the surrounding small holes, round the edge of the center hole to obtain blank 101;
[0028] 2) Integrated punching and spinning:
[0029] 2.1) Reference image 3 , Install the blank 101 on the cone surface of the lower die 3 of the integrated punching and spinning equipment;
[0030] 2.2) Reference Figure 4 with Figure 5 , The mold is closed to complete the inner hole flanging: the upper mold 2 moves to the lower mold 3 until the upper mold 2 and the blank 101, the lower mold 3 and the blank 101 are completely attached, so that the blank 101 realizes the inner hole flanging, and the primary workpiece 102 is obtained;
[0031] 2.3) Refer...

A method for integrally forming filter flanges by punching and spinning. First, a circular plate is used to punch out the center hole and surrounding small holes, and the edge of the center hole is rounded to obtain a blank; Install the billet on the conical surface of the lower die of the punching and rotating integrated equipment, and the upper die moves to the lower die until the upper die and the billet, and the lower die and the billet are completely attached, so that the billet can realize the flanging of the inner hole and obtain the primary workpiece; the upper die The clamping position of the mold and the lower mold remains unchanged, and the primary workpiece is clamped. The upper mold is also used as a core mold for spinning, and the lower mold is also used as a tailstock for spinning. first-level workpiece; then correct the secondary workpiece to obtain the final-level workpiece; finally trim the edge of the final-level workpiece to obtain the filter flange. The invention effectively reduces the number of mold sets, shortens the forming time, and reduces the production cost.
Description
Technical field [0001] The invention belongs to the technical field of filter flange forming, and in particular relates to a method for forming a filter flange by flushing and rotating integrally. Background technique [0002] Automotive filters are indispensable parts to ensure the normal operation, reliability and durability of automobile engines. Oil filters play an important role in ensuring the normal operation of the lubrication system and extending the service life of the oil. The oil filter housing and end flanges are generally stamped and formed. [0003] Due to the complicated structure and high performance requirements of the end flange of the oil filter, its stamping and forming process has undergone multiple steps, several passes and multiple intermediate stress relief annealing. The typical stamping forming process mainly includes one punching (peripheral small holes), two deep drawing, one trimming, one punching (center hole), and one flanging (inner hole flanging)....
