Scope

GB/T 42596.1-2023 is the English-translated version of 机床安全压力机第1部分：通用安全要求.

GB/T 42596.1-2023 is Part 1 of the Chinese series on press safety, and sets the general safety requirements.

Presses amputate more hands than any other class of machine tool, and always in the same way: the operator's hand is in the die area when the slide comes down, either because the guarding was defeated to speed up the work or because the machine repeat-stroked when it should not have.

Everything in the standard follows from that.

It defines the press categories used across the series, the press components and control functions, and the operating modes, then lists the significant hazards and sets the safety requirements: the basic design, the mechanical hazards in the die area, the control and monitoring system, die adjustment, stroke adjustment, maintenance and lubrication, the other mechanical hazards, slips, trips and falls, and protection against other hazards, followed by the verification and the information for use. It took effect on 1 December 2023.

Foreword

This document specifies technical safety requirements and measures to be adopted by persons undertaking the design, manufacture and supply of presses which are intended to work cold metal or material partly of cold metal.

This document applies to presses which can function independently and can also be used as a guide for the design of presses which are intended to be integrated in a manufacturing system.

The covered presses transmit force mechanically to cut, form, or work cold metal or other sheet materials by means of tools or dies attached to or operated by slides/ram in range in size from small high speed machines with a single operator producing small workpieces to large relatively slow speed machines with several operators and large workpieces.

This document does not cover machines whose principal designed purpose is:

a) metal cutting by guillotine;

b) attaching a fastener, e.g. riveting, stapling or stitching;

c) bending or folding by press brakes or folding machines;

e) turret punch pressing;

g) drop forging or drop stamping;

h) compaction of metal powder;

i) single purpose punching machines designed exclusively for profiles, e.g. used in the construction industry;

l) working by pneumatic hammer.

This document is not applicable to presses which are manufactured before the date of its publication.
