Description
Technical Field
The invention relates to a machining part manufacturing method, in particular to a method for machining a cross beam of a printing machine.
Background
The cross beam of the printing machine is a metal machining part, and special coating needs to be sprayed on the surface of the cross beam to ensure the durability of the cross beam; the machined surface needs to be kept smooth, so the whole body is subjected to sand blasting before milling, and then the machined surface is milled cleanly through milling; the reworking after the sand blasting affects the sand blasting quality, resulting in low paint adhesion.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for processing the cross beam of the printing machine, which improves the processing technology and the paint adhesion effect on the surface of the cross beam.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a method for processing a cross beam of a printing machine,
step A: tempering the materials:
reheating and preserving heat of the quenched material, and then naturally cooling to normal temperature; tempering the material can improve the use performance of the workpiece, reduce brittleness, reduce internal stress and stabilize the size of the workpiece.
And B: milling a product:
milling the tempered material by using a milling machine tool to obtain a formed beam;
and C: installing an anti-baking jig:
installing an anti-roasting jig on the milling surface of the cross beam; the protective jig is additionally arranged on the machined surface, the milled surface is protected, the damage to the milled surface caused by subsequent machining is prevented, and the beam machining quality is improved.
Step D: product surface sand blasting:
impacting the surface of a beam product by using high-speed sand flow, removing black skin generated on the surface of the product during tempering, and improving the roughness of the surface of the beam; the sand blasting can establish an important basic rough surface on the surface of a workpiece before spraying, can increase the roughness of the surface of the workpiece, improve the mechanical property of the surface of the workpiece, improve the fatigue resistance of the workpiece, increase the adhesive force between the workpiece and a coating, improve the durability of the coating and facilitate the leveling of the spraying coating.
Step E: spraying a coating:
spraying paint on the surface of the product;
step F: demolish and prevent roast tool:
and (5) removing the anti-baking jig after the coating is dried.
Further, the method comprises the following steps: and B, spraying cutting fluid while milling.
Further, the method comprises the following steps: and C, installing the anti-baking jig in the step C on the product processing surface through screws. The installation of the anti-baking jig is carried out by utilizing the threaded hole on the processing surface of the workpiece, so that the influence of the jig on the sand blasting and spraying of the workpiece can be reduced to the greatest extent.
Further, the method comprises the following steps: and D, selecting carborundum as the abrasive material for sand blasting in the step D. The carborundum has high hardness and specific gravity, and can form larger impact force on the surface of a workpiece by using compressed air as power, play a role in cleaning and rough surface, remove grease in cutting fluid on the surface of a product and improve the adhesiveness of the coating.

Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1, a cross beam processing method of a printing press,
step A: tempering the materials:
reheating the quenched materials, preserving heat, and naturally cooling to normal temperature;
and B: milling a product:
milling the tempered material by using a milling machine tool to obtain a formed beam;
and C: installing an anti-baking jig:
installing an anti-roasting jig on the milling surface of the cross beam;
step D: product surface sand blasting:
impacting the surface of a beam product by using high-speed sand flow, removing black skin generated on the surface of the product during tempering, and improving the roughness of the surface of the beam;
step E: spraying a coating:
spraying paint on the surface of the product;
step F: demolish and prevent roast tool:
and (5) removing the anti-baking jig after the coating is dried.
On the basis, cutting fluid is sprayed while milling in the step B. The cutting fluid can play a role in lubrication, cooling and cleaning, can reduce the friction between the cutter face and the cutting chips, forms partial lubrication and reduces energy consumption. In this example, a water-based cutting fluid was used, which had better cooling performance.
On the basis, the anti-baking jig in the step C is installed on the product processing surface through screws. The anti-baking jig is also made of metal materials, and can be used for multiple sand blasting and spraying for repeated use.
On the basis, the abrasive material for blasting sand in the step D is carborundum. The residual cutting fluid on the surface of the product can be removed in the sand blasting process, so that the smoothness of the surface of the product is reduced, the roughness is increased, and the adhesiveness of the coating is improved; the abrasive for sand blasting can be selected from carborundum, quartz sand, copper ore sand, iron sand and the like. The diamond grains have the advantages of high hardness and high specific gravity, and are ideal sand blasting materials, and the diamond grains are used as the sand blasting materials in the example.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
