What Are The Safety Regulations For Operating A Power Hammer

One machine that is indispensable when engaged in any form of metal shaping and forming is a power hammer, especially if it is one that is multi-functional and can do many different tasks. A 50 Herz, 220 volt single-phase multi-hammer has the ability to perform many different styles of operations in one machine and can be used for short-stroke shaping and flanging. Profiles and designs are endless with options such as stretching dies, mechanical shrinking, louvres and flanging dies.

A power hammer makes use of an inverter to reach various operation speeds ranging from 0 ?1500 bpm. The speed can be adjusted in two ways: with an operator controlled foot-pedal or from an operator panel where the speed can be locked in. Another feature of the power hammer is stroke adjustments ranging from 0175 inches to .550 inches.

Safety Regulations For Power Hammers

The Occupational Safety and Health Administration of U.S. Department of Labor has set the following regulation standards for safety of power hammers:

– Hammers are to be positioned in a manner that ensures that they remain on, or that they are anchored to a foundation that is sufficient to support the hammer according to appropriate engineering standards.
Presses are to be installed in manner that ensures that they remain stationery or that they are anchored to a foundation that is sufficient to support the press in accordance with appropriate engineering standards.
– Means must be provided to disconnect the power to the hammer and to lock out or render cycling controls inoperable.
– The ram must be blocked when work is being done or when dies are changed on the hammer.
– Wedges or blocks must be made of materials with the strength and construction to meet or exceed the dimensions and specifications set out in Table 0-11 in the occupational safety guide.
– Tongs must be of sufficient length in order to clear the body of an operator in case of kickback and must not have sharp ends on the handles.
– Scale removers, oil swabs or other scale removing devices must be provided that are sufficient in length to enable an operator to reach the entire length of the die without having to place a hand or an arm in between the dies.
– Material handling equipment must e of adequate size, strength and dimension to safely handle die-setting operations.
– A scale guard with substantial construction must be provided at the back of the hammer and arranged in such a way that it will block flying scale.
– A scale guard must be provided at the back of the press with construction substantial enough and arranged in such a way to block flying scale.

General Safety Guidelines For Power Hammers

– All die keys and shims must be made of a material grade that will withstand undue cracking or splintering.
– All devices operated by foot such as pedals, valves, treadles, bars and switches must be effectively and substantially protected from accidental or unintended operation.
– All manually operated press valves and switches must be readily accessible and clearly identified.
– All air or steam hammers must have a safety cylinder-head that acts as a cushion should the rod pull out of the ram or break.
– All steam hammers must be provided with a quick-closing emergency valve at a convenient location in the admission pipeline. The emergency valve must be closed and locked in the position while the hammer is under repair, being serviced, adjusted, or when dies are in the process of being changed.
– Steam hammers must be provided with a cylinder draining method such as a quick-acting drain cock or a self-draining process.

Power hammers http://ellsenwroughtironmachine.com/power-hammer/ are a source of danger and should be vigilantly operated and controlled at all times. All major fittings and assemblies related to power hammers which can become loose and fall should be properly secured and kept in place to minimize the risk of accidents and injury.
