GB/T 15784-2009Programming method for converted timber machine (English PDF)

Foreword

This standard replaces GB/T 15784-1995 "sawing machine model designation." The main difference compared with the standard GB/T 15784-1995 as follows:

--- To increase conversion coefficient of the second main parameter;

--- Increase group name mechanical system. This standard was proposed by the State Forestry Administration. This standard by the National Standardization Technical Committee panel machinery. This standard was drafted. Xinyang Woodworking Machinery Co., Ltd. The main drafters of this standard. Hu Dedi, Shen Wen, Li Xinmin, Wang Xihong, Han Hui. This standard replaces the standards previously issued as follows:

--- GB/T 15784-1995. Lumber machinery Model methodology

1 Scope

GB/T 15784-2009 is the Chinese national standard on programming method for converted timber machine, in the field of agriculture. 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 30 November 2009 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 January 2010. Classification: ICS 65.060.80, CCS B90. 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 method for the preparation of lumber mechanical models. This standard applies to the preparation of various types of lumber saws, lumber cars, lumber auxiliary equipment, grinding equipment, lumber mechanical model in.

2 Lumber machinery models

2.1 Model Representation Lumber mechanical models are structured as follows: lumber machine code classification code () general characteristics and structural characteristics of the code group code Department Code main parameters (/ ) second main argument (-) significant improvements sequence number

Note 1. "-" symbol, serving capital phonetic alphabet.

Note 2. "" symbol, serving Arabic numerals.

Note 3. "()" symbol who, when no content is not expressed, if the content should not be bracketed.

2.2 sawing machinery classification code Lumber machinery is divided into four categories according to the functions, classification code Pinyin letters (see Table 1), located behind lumber machine code. Table 1 lumber machinery classification code Category lumber sawn timber car mechanism lumber auxiliary grinding equipment Code J C F M

2.3 lumber mechanical characteristics of the code

2.3.1 lumber mechanical properties of common code Lumber mechanical properties of common code Pinyin letters (see Table 2), located after the classification code. In the model represents only the most The main one common feature. Table 2 lumber mechanical properties of common code General features semi-automatic digital program-controlled universal Code Z B K W Structural characteristics

2.3.2 lumber machine code Mechanical properties of structural lumber code in the general characteristics of the code after, left the users "(Z)" represents the right to not express.
