3 Terms and Definitions
GB/T 15706.1 as defined in the following terms and definitions apply to this document.
3.1
JHA area hazardzoneofworking
Completion of the regional workpiece on forging machinery. As for the working parts from time to time as the relative motion of the working parts of the reciprocating linear motion
Or flame, laser, high-pressure fluid; mold installation space (including attachments) on the work surface projected on the direction of travel included
And the space between the workpiece contains.
3.2
Direction of the work stroke workingstroke
Working parts forging machinery reciprocated from the full open position to a fully closed position of the stroke.
3.3
Safe distance safetydistance
Protection work between the danger zone and ensure the safety of the minimum distance.
3.4
Co-operating multi-synchronousactuation
Two or more operators during joint operations, each operating simultaneously manipulation device with both hands, in order to start working parts
the way.
3.5
Security Bar safetycolumn, safetyscotch, mechanicalrestraintscotch
When forging mechanical adjustment or repair the mold, placed between the bottom surface of the mold member or work with the table plate to prevent the working portion

5.1.1 Design of forging machinery and spare parts, attachments should be consistent with GB 5083, GB/T 15706.1, GB/T 15706.2 and this mark
Registration requirements. Forging machinery design should be taken to reduce risk assessment and risk measures.
5.1.2 The danger can not be avoided by design, safety precautions should be taken. For the design can not take safety measures to avoid
Free dangerous legacy application information notification or alert the operator.
5.1.3 There should be no sharp edges result in personal injury, sharp corners (except function required).
5.1.4 Screw forging machinery, nuts and other fasteners and pins, because of its loose parts fall off will cause displacement, drop caused by accident
Should adopt a reliable anti-rotation.
5.1.5 Forging Machinery shall own structural characteristics, technology objects and set the appropriate mode of operation of safety devices and blocking devices.
5.1.6 Forging Machinery should be its own structural features, set the appropriate security surveillance and control device for the safety of the health of forging machinery
Monitoring.
5.1.7 working parts reciprocating forging machinery, should be required to set safety bolt, and should be the main drive or control system working parts
Interlock.
5.1.8 may produce forging machinery around dangerous, such as CNC punch turret press, CNC laser (or flame, high-pressure water) cutting machine to send
Around the intake device or the like, should be set to block devices.
5.1.9 forging machinery should not be overturned in the accident under predetermined conditions, move or fall, due to structural reasons can not guarantee stability, we should say
Ming stabilization measures.
5.1.10 pressure vessels, including accumulator design, manufacture should be consistent (all parts) requirements GB 150.
5.2 Transmission
5.2.1 General requirements
Transmission structure 5.2.1.1 forging machinery should be safe and reliable.
5.2.1.2 may cause wound, inhaled or involved in dangerous moving parts and transmission should be set safety devices, safety is not affected
