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 Figure 1-Figure 4 As shown, the present invention will be further described with respect to the processing method of the head shown in the figure below.

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

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

[0036] S20: Scribe, draw a circle on the board according to the design size requirements, as the basis of the blank size.

[0037] S30: Blanking, cutting the plate to form a wafer.

[0038] S40: Open a hole, fix the wafer, and open a through hole on the CNC machine tool to form the orifice plate 1. In this embodiment, the CNC machine tool selects a CNC hole drilling machine.

[0039] S50: Stamping, cold stamping the orifice ...

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 sealing head, in particular to a processing method of an opening sealing head. Background technique [0002] The existing mixing equipment or sewage treatment equipment has an open-hole head, which is used to filter the larger particles in the mixing mixture or the large impurities in the sewage. When in use, the port of the head and the discharge port of the mixing equipment Or welding the sewage outlet of sewage treatment equipment. At present, there are generally two ways to produce the head in China. One is to punch the wafer and then punch it, and the other is to punch the wafer after it is punched. The opening on the former forming head is generally processed by a machining center or manual scribing. Machining center processing equipment investment is large, because the surface of the hole is non-planar, the design of fixture and CNC programming is extremely difficult, and the processing cost is ...
