Description

Technical Field

[0001] The present application relates to the technical field of grinding machine casting manufacturing, and in particular to a V-method casting process and processing equipment for high-precision molded grinding machine box castings. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers. The grinder box is mainly used to support and fix the various components of the grinder to ensure stability and accuracy during the processing. The grinder box is the basic supporting structure of the grinder. Its main functions include supporting and fixing the various components of the grinder (such as the spindle, worktable, slide, etc., to ensure the stability and accuracy of these components during the processing), providing a stable processing environment (the structural design of the box can ensure the stability and rigidity of the grinder during operation, reduce vibration and deformation, thereby improving processing accuracy and surface quality) and protecting the internal mechanical structure (it has sealing and lubrication functions, which can protect the internal mechanical structure from external dust and impurities and extend the service life of the equipment).

[0003] The box is usually cast, using a machined wooden mold and a resin sand box molding process. The production process is as follows: the processed wooden mold is placed in the sand box, and then the resin sand is filled into the sand box and compacted to form the cavity of the mold. The upper and lower sand boxes are combined to ensure that the parting surface is flat and tightly fitted to prevent the metal liquid from leaking, and the molten metal liquid is poured into the mold. This process requires controlling the pouring speed and temperature to ensure that the metal liquid can evenly fill the entire mold cavity. Cooling and unpacking: After the metal liquid cools and solidifies, open the sand box and take out the casting. This process requires careful operation to avoid damaging the casting or the sand box. The removed casting is cleaned to remove excess burrs and gate residues. Then, post-processing operations such as heat treatment and machining are performed as needed to improve the mechanical properties and surface quality of the casting.

[0004] However, customers of high-precision molding grinder boxes require a shorter production cycle, but the wooden mold model production cycle is long, with a set of molds taking 15-20 days, resulting in a longer production cycle; high costs, the process has high requirements for model accuracy, and can only be a machined model, with high model manufacturing costs; and low production efficiency.
