Problems solved by technology

The equipment for processing in the machining center has a large investment. Because the surface of the hole is non-planar, the design of the tooling fixture and NC programming is extremely difficult, and the processing cost is also high. Low
In the latter, due to the decrease in the strength of the wafer after the hole is opened, direct stamping will cause cracks at the hole, resulting in product scrapping

Embodiment

[0033] Please refer to Figure 1-Figure 4 As shown, the present invention will be further described below with regard to the processing method of the head shown in the figure.

[0034] Processing the perforated head includes the following steps:

[0035] S10: Material selection. In this embodiment, a stainless steel plate with the brand name 06Cr18Ni11Ti is selected. This stainless steel plate has good wear resistance and can effectively prevent block solids from abrading the head during the working process of the stirring equipment or sewage treatment equipment.

[0036] S20: Draw a line, draw a circle on the plate according to the size requirements of the design, as the basis for the blanking size.

[0037] S30: blanking, cutting the plate to form a disc.

[0038] S40: Drilling, fixing a point on the wafer, opening a through hole on the CNC machine tool to form an orifice plate 1. In this embodiment, the CNC machine tool selects a CNC drilling machine.

[0039] S50: Stamp...

Abstract

The invention discloses a machining method for a trepanning shell cover. The machining method comprises the steps of material selection, marking, blanking, trepanning, stamping, taking, grooving and grinding and acid pickling. Cushion plates are placed on the upper surface and the lower surface of a pore plate respectively. In the stamping process, the cushion plates support the pore plate from beginning to end, and therefore it is avoided that the pore plate cracks due to insufficient compressive strength in the stamping process. Compared with a traditional machining method, the machining method for the trepanning shell cover has the advantages that operation is easy, machining efficiency is high, and product quality is good.

Description

technical field [0001] The invention relates to a manufacturing process of a head, in particular to a method for processing a holed head. Background technique [0002] Existing mixing equipment or sewage treatment equipment have open-hole sealing heads, which are used to filter larger particles in the stirring mixture or larger impurities in sewage. When in use, the port of the sealing head and the outlet of the mixing equipment Or the sewage outlet of the sewage treatment equipment is welded. At present, there are generally two ways to produce the head in China, one is punching the disc and then punching it, and the other is punching the disc after punching. The openings on the former forming head are generally processed by machining centers or manual marking. The equipment for processing in the machining center has a large investment. Because the surface of the hole is non-planar, the design of the tooling fixture and NC programming is extremely difficult, and the proces...
