Embodiment 1

[0044] Fixed perforated plate: eg figure 2 As shown, the diameter of the perforated plate (3) is 2460mm, and the thickness is 20mm. According to the diameter of the perforated plate (3), the size of the positioning plate (6) is determined to be 2600*2600*30mm, and the inner hole layout of the perforated plate (3) is 14mm. Arrange in a regular triangle, determine the position of the drilling and tapping according to the layout of the inner holes of the perforated plate, the horizontal distance is 15 hole distances, and the longitudinal distance is 16 rows, determine the number of drilling and tapping required, and prepare a corresponding number of nylon blocks ( 4), bolts (1) and washers (2). Afterwards, fix the positioning (6) plate on the workbench, align and determine the coordinate center, and carry out scribing, drilling, chamfering and tapping according to the planned layout. Bond the corresponding number of nylon blocks (4) to the positions of the bolt holes with AB gl...

Embodiment 2

[0047] The mode of fixing perforated plate is the same as embodiment 1;

[0048] Machining the inner hole of the perforated plate: use a 9.7mm internal cooling drill to process the bottom hole of the perforated plate 3, the rotational speed of the internal cooling drill S=1200r / min, and the feed rate F=90mm / min to obtain a 9.7mm bottom hole, and the inner hole of the bottom hole The hole roughness reaches Ra3.2; then use the chamfering drill to perform front chamfering, the chamfering drill speed S=900r / min, the feed speed F=120mm / min, after processing, the angle of 1x45° is obtained; then use S08K-SCLCR06 The boring tool performs boring on the inner hole, the speed S=750r / min, the feed speed F=100mm / min, and a smooth 9.9mm-10mm finished inner hole is obtained, and the inner hole roughness reaches Ra0.4-0.5; and then Use the mirror rolling tool to roll the inner hole, the mirror rolling tool speed S=900r / min, the feed speed F=125mm / min, to obtain the inner hole with an inner d...

Abstract

The invention belongs to the technical field of chemical equipment, and particularly relates to a machining process for improving the roughness of an inner hole of a porous plate of chemical equipment. The machining process aims to solve the problems that the porous plate deforms during machining and the smoothness of the inner hole is low. The machining process comprises the steps of adopting a positioning tool for fixing, and then machining the inner hole through a complete machining process of drilling, chamfering, boring and mirror surface rolling of an inner cooling drill bit so as to meet the requirement that the smoothness of the inner hole is Ra0.1. According to the machining process, the roughness of the inner hole of the porous plate can be improved, the roughness of the inner hole can be Ra0.1, and the circulation of viscous materials passing through the hole can be guaranteed; and the porous plate is not prone to deformation, and the machining quality is not affected.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a processing technology for improving the inner hole roughness of a porous plate of chemical equipment. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In the process of traditional mechanical processing, when processing tube sheets, more attention is paid to the spacing of tube holes and the tolerance of tube diameters, and the requirements for the roughness of the inner holes are not high. Can. The perforated plate used in chemical equipment is more prominent in the requirements of the roughness of the inner hole to ensure the fluidity of the inner hole when the ...
