Introduction

GB/T 46639 covers casting machinery used in casting production.

Casting, as a metal heat treatment process that involves filling a mold with molten metal and allowing it to solidify to obtain parts or part blanks, has a long history.

History, and its technology is constantly developing and changing. Depending on the mold used, or the method of filling or solidification of the molten metal, it varies.

Depending on the method, there are many different casting processes, such as sand casting, investment casting, lost foam casting, die casting, low-pressure casting, and metal mold casting.

Force casting and centrifugal casting, etc.

GB/T 46639, as the fundamental standard for casting machinery, defines each concept applicable to the general application of casting machinery.

The scope covers various casting equipment for different casting methods and different production process stages.

GB/T 46639 is proposed to be divided into the following 6 parts.

---Part 1: Fundamentals. The purpose is to define the basic terminology and definitions of casting machinery.

---Part 2: Molding, Core-Making Machines and Other Non-Permanent Casting Equipment. The purpose is to define molding machines, core-making machines, and other non-permanent casting equipment.

Terminology and definitions for long-form casting equipment.

---Part 3: Die Casting Machines and Other Permanent Casting Equipment. The purpose is to define the technical specifications of die casting machines and other permanent casting equipment.

Language and definition.

---Part 4: Shot blasting machines and other casting cleaning equipment. The purpose is to define shot blasting machines and other casting cleaning equipment.

Equipment terminology and definitions.

---Part 5: Cupolas, Casting Equipment and Ladles. The purpose is to define the terminology and definitions for cupolas, casting equipment and ladles.

---Part 6: Other. The purpose is to define the casting machinery-related terms and definitions not covered in Parts 1 through 5.

This document is Part 4 of GB/T 46639, and only covers the terms and definitions for shot blasting machines and other casting cleaning equipment, including...

Structural features, functions, and key components of various shot blasting machines, riser removal devices, core removers, grinding machines, and other related equipment.

Basic concepts of components, main processes and parameters.

The formulation of GB/T 46639 provides a foundation for the development and revision of standards in the field of casting machinery, as well as for technical documents and related scientific and technological publications.

It provides a unified basis for terminology.

3 Terms and Definitions

The following terms and definitions apply to this document.

Abrasive blasting; shot blasting the process of using abrasive materials to continuously impact a workpiece or surface to be cleaned in order to achieve the desired effect.

[Source. ISO 23472-1:2020, 3.1] 3.2 A machine that uses centrifugal force or compressed air as an abrasive acceleration method to complete the shot peening cleaning process.

Abrasive cut-off machine; grinding cutter A device that uses a high-speed rotating cutting wheel to cut the gating system or other metal materials in castings.

Abrasive media; shotblasting media A particulate metal or non-metal material that is forced to the surface of a workpiece to achieve the desired effect.

Note. For the classification of metallic abrasives, see ISO 11124-1; for the classification of non-metallic abrasives, see ISO 11126-1.

[Source. ISO 23472-1:2020, 3.3] 3.5 Bullet circulation system in a shot peening machine, a mixture of abrasive and cleaned material is collected, and the abrasive is separated from the mixture for supply.

A system for shot peening.

Note. This system typically consists of a bucket elevator, screw conveyor, shot separator, vibrating screen, shot storage hopper, shot gate, and shot flow pipe.

A device that uses gravity, airflow, screens and/or magnetism to remove impurities from used abrasives and separate reusable abrasives.
