What is De-coring hammer?

More energy efficient and efficient

de-coring hammer

A cost-effective pneumatic core removal tool.

De-coring work for cast aluminum,cast steel,and other castings where internal sand core removal is difficult or sand core remains

  • The vibration frequency is about 2-3%high(refer to the market with the same model)
  • The vibration frequency is higher,the sand cleaning and core removal effect is better.
  • Shorter vibrating cycle and efficient productivity
  • Simple structure,high reliability and long service life
  • Provide spare parts replacement service for all parts of the De-coring hammer
  • The 70plus series of De-coring hammers are identical in size to the same model of the similar products in France and Italy,and can be completely replaced by interchange
  • Personalized custom-made larger or smaller De-coring hammer that provides an increase or decrease
  • The installation parts are freely customizable and the installation range is more flexible.

Same size as similar products
in France and Italy, easy to install

Types of De-coring hammer

Higher frequency,clear sand and de-coring is better

Depending on the customer's request,we can offer De-coring hammer made of different performance parameter,in various grades of Vibration frequency,depending on the application.

Notes:

*Recommended maximum air pressure 6bar

*Recommended to use the Mobil Aimeur 525 ISO VG 46 as the recommended lubricant

*Please be sure to clean when installing the pneumatic hammer.Remember not to bring dirt from the air hammer inlet into the hammer.

Principle of De-coring hammer

Design Science Environmental Protection and Energy Conservation

The compressed air is used as the power source,and the air source switch is turned on,and the internal inner shaft tube assembly of the De-coring hammer is pushed out by the compressed air pressure until the front end hammer head presses the workpiece to be removed;

The switching of the position of the airflow reversing plug in the inner shaft tube assembly guides the airflow to make the piston rod perform periodic high frequency reciprocating impact on the hammer head,and the high frequency impact force generated by the piston rod is transmitted to the workpiece through the hammer head and then transmitted to the sand inside the workpiece.The core functions to separate the sand core,the sand core and the workpiece,thereby achieving the purpose of efficiently removing the sand core.

Parts list of De-coring hammer

Simple structure and high reliability

De-coring hammer must be lubricated regularly with lubricating oil.

We recommend lubrication with Mobil Amour 525 ISO VG 46.Each De-coring hammer needs to be lubricated separately(20-30 seconds for one cycle,one drop every 3-4 seconds).

If you have not used the De-coring hammer for a long time,you must use a degreaser to clean the inside of it.

After 510 hours of operation,De-coring hammer is recommended to inject the degreaser(recommended grade:Zep Dyna143)from the air inlet without removing the De-coring hammer from the core remover.

warning:

In order to ensure that multiple De-coring hammers on a single device can work properly,each De-coring hammer needs to use the same diameter and length of the pipeline.

It is forbidden to use De-coring hammer without hammer and casting!

It is forbidden to use a pneumatic hammer without the workpiece that needs to be removed.

Precaution:

When working for 300 hours or more,the De-coring hammer should be protected,inspected,cleaned,and the degreaser injected from the inlet.You do not need to remove the De-coring hammer from the core remover.

Notes:

“ ●” The service life depends on the working environment conditions,such as the temperature of the struck casting.

“ /” The Needs to be replaced after 1550 hours of hammering time,but if the distance between the hammer and the casting(ie the strike distance)is not within the specified distance,such parts need to be replaced after 1020 hours of hammering time.

“ *” The In order to prevent and maintain the De-coring hammer(after hammering for 510 hours or a little longer),these parts need to be repaired or replaced.

“ #” The These parts are recommended for replacement each time maintenance is performed.

Safety and maintenance De-coring hammer

Provide spare parts replacement for all parts of the De-coring hammer

warning:

All parts must be our products.Using parts from other sources will reduce the safety of use and ensure the safety of De-coring hammer.

The company is not responsible for products that do not use the original spare parts.

Maintenance:

After the De-coring hammer is disintegrated,complete the following steps:

Check the condition of each part,clean them or replace them.Reassemble the De-coring hammer step by step according to the reorganization steps.After reorganization,the De-coring hammer must be lubricated with Mobil Intermediate Lubricants.

Safety Guide:

Follow the instructions for use.

When the De-coring hammer is not working properly,cut off the air supply.

When the noise of the De-coring hammer exceeds 85DB,measures to block noise(ear headphones,etc.)are required.

Air supply:

To prevent damage,contamination,or rust in the De-coring hammer,use an air handling unit to ensure that the air supplied to the De-coring hammer is dry and clean.

The required accessories,lines,and pipes must be of appropriate size,consistent with the required air pressure,intake air volume,air output,and volume to avoid the pipe being too narrow(inappropriate use of the air pipe),resulting in insufficient air supply.
