Manufacturing process of cross beam of planer type milling machine

Abstract

The invention discloses a manufacturing process of a cross beam of a planer type milling machine. The manufacturing process comprises the following steps: making a mold of the cross beam of the planer type milling machine; putting resin sand into a mold so as to make a resin sand model; drying and patching a modeled casting mold; brushing a coating at the surface of the casting mold; preparing a pond furnace material; filling the pond furnace material into an intermediate frequency furnace to obtain a pond furnace; drying the pond furnace; making a fire in the intermediate frequency furnace; loading materials into the pond furnace; smelting materials in the intermediate frequency furnace; opening the intermediate frequency furnace to release molten iron; pouring the molten iron into a cast mold by using a crane ladle for pouring; staying the cast mold for 1-5 minutes; when a solidified layer reaches a desired thickness, pouring out excessive molten iron; after the cast mold is cooled, cleaning the cast mold so as to obtain a desired cast; carrying out shot-blasting to the cast; polishing and cleaning the cast; and brushing an anti-rust paint to the cast so as to obtain a finished product. The manufacturing process of the cross beam of the planer type milling machine, disclosed by the invention, has the advantages as follows: the production can be continuously carried out, the lifting is reduced, the production efficiency is increased and the production cost is reduced.

Description

Technical field:

[0001] The invention relates to a manufacturing process of a beam of a gantry milling machine. Background technique:

[0002] At present, most of the beams of the existing gantry milling machines adopt decentralized processing methods, including cross-cutting, sanding, cutting, bending and other processes. These processes are scattered operations. After each process is completed, they need to be stacked and lifted separately. The production efficiency is low, the production area is large, and more workers are required, and the labor intensity of the workers is high. Bending consumes a lot of energy and produces a lot of noise, which is not conducive to environmental protection. Invention content:

[0003] The object of the present invention is to overcome the above disadvantages and provide a manufacturing process for the crossbeam of a gantry milling machine that can be produced continuously, reduce hoisting, improve production efficiency, and reduce pro...
