Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, a printing machine beam processing method,

[0024] Step A: Material Tempering:

[0025] The quenched material is reheated and kept warm, and naturally cooled to normal temperature;

[0026] Step B: Product Milling:

[0027] The tempered material is milled by a milling machine to obtain a formed beam;

[0028] Step C: Install the anti-bake fixture:

[0029] Install anti-baking fixtures on the milling surface of the beam;

[0030] Step D: Sandblasting the product surface:

[0031] Use high-speed sand flow to impact the surface of the beam product, remove the black skin on the surface of the product during tempering, and improve the roughness of the beam surface;

[0032] Step E: Spray the paint:

[0033] Spray paint on the surface of the product;

[0034] Step F: Remove the anti-bake fixture:

[0035] ...

Abstract

The invention relates to the field of machined part preparation methods, and discloses a method for machining a cross beam of a printing press. Tempered materials are milled, an anti-baking jig is mounted on a milled face, and then sand blasting process treatment is carried out; the product surface is cleared and roughed, the roughness of the product surface is improved, and the adhesiveness of asubsequent coating is improved; and finally the coating is sprayed, and after the spraying is aired, the anti-baking jig is removed. High-speed sand flow is utilized for impacting on the surface of the cross beam product, black skin generated on the product surface during tempering is removed, and the roughness of the surface of the cross beam is improved; a very important basic rough surface canbe built on the workpiece surface through sand blasting before spraying, the roughness of the workpiece surface can be improved, the mechanical performance of the workpiece surface can be improved, and the fatigue resistance of the workpiece can be improved; and the adhesive force before the workpiece and the coating is improved, the durability of the coating can be improved, and sprayed coating leveling is convenient.

Description

technical field [0001] The invention relates to a method for preparing machined parts, in particular to a method for processing a beam of a printing machine. Background technique [0002] The beam of the printing machine is a metal machined part. In order to ensure its durability, special paint needs to be sprayed on the surface of the beam. Because the metal surface is relatively smooth, it is usually necessary to sandblast the smooth metal surface to increase the roughness of the metal surface. Degree; the machined surface needs to be kept smooth, so usually the whole surface is sandblasted before milling, and then the machined surface is milled clean by milling; after sandblasting, processing will affect the quality of sandblasting, resulting in low coating adhesion. Contents of the invention [0003] The technical problem solved by the invention is to provide a method for processing the beam of a printing machine, which improves the processing technology and improves t...
