Embodiment Construction

[0011] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0012] Depend on figure 1 It can be seen that, when the metal plate 8 is stamped by the mold, the following steps are included:

[0013] 1. During the downward movement of the upper die, first punch the metal plate 8 through the part 1 of the upper die;

[0014] 2. The part 6 of the lower die cooperates with the annular groove 4 on the upper die to realize the flanging of the edge of the punched through hole, and the matching of the part 2 on the upper die and the upper blind hole 7 of the lower die. Stretch the outside of the edge;

[0015] 3. Blanking and punching are carried out through the cooperation of the part 3 of the upper die and the edge part 5 of the lower die.

[0016] After the above steps, it is obtained as figure 2 Shown is the semi-finished product 9 of the sealing ring fixing plate.

[0017] Will figure 2 The semi-finished product 9 shown...

Abstract

A technology for processing a rotatable filter sealing ring fixed plate is completed on a die by a stamping way and comprises the following steps of punching a metal sheet, flanging the edge of the punched hole, extending the external side of the flanging part, blanking and cutting to obtain a semi-finished product; and folding the edge of the semi-finished product and the flanging position of the through hole on the semi-finished product. The technology has reasonable process; and compared with the existing machining process, the technology has the active effects of less processing and dies investment, higher productivity, lower material consumption and reject rate, and the like.

Description

technical field [0001] The invention relates to a processing technology for a fixing plate of a sealing ring of a spin-on filter. Background technique [0002] The sealing ring fixing plate is a key part of the spin-on filter, and it plays a sealing role after being engaged with the filter housing. At present, the processing of the sealing ring fixing plate is completed on the mold by stamping. The existing processing steps for the sealing ring fixing plate are: (1) blanking and stretching the metal sheet; (2) punching 1. Flange the edge of the hole; (3) Fold the edge of the hole; (4) Trim and fold the edge of the semi-finished product. The disadvantage of this existing processing method is: the method of stretching first and then punching, the deformation of the material during stretching depends entirely on the shrinkage of the outer edge of the sheet, which will cause poor uniformity of the edge of the semi-finished product. Therefore, it is necessary to Trimming increa...
