Foreword

The standard proposed by China Machinery Industry Federation. This standard by the National Forging Machinery Standardization Technical Committee (SAC/TC220) centralized. This standard was drafted. Anyang Forging Machinery Industry Co., Ltd., Jinan Foundry and Metalforming Machinery Research Institute, Shenzhen City, measuring Detection limited the company. The main drafters of this standard.

1 Scope

GB/T 25718-2010 is the Chinese national standard on electro hydraulic forging hammer - type and basic parameter, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2011. Classification: ICS 25.120.10, CCS J62. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the types and basic parameters of electro-hydraulic hammer. This standard is applicable to the anvil type, gas-liquid-driven and hydraulically driven electro-hydraulic hammer.
