Regarding the type CHK PLC fully-hydraulic die forging hammer with large size, there is rather heavier framework and rather higher investment about equipment, anti-vibration foundation and transportation. Therefore, when requiring for large size forging hammer with striking energy more than 100KJ,we suggest you choose non-anvil to substitute.
Just as the name implied, the counterblow hammer is a kind of hammer that the upper tup and the low tup strike each other with equal energy.
In the early 70’s,Baixie is collaborated with China Taiyuan Heavy-duty Machinery College to co-develop the first set 63KJ hydraulic counterblow hammer in China ,and in the 80’s further introduced the technology 100KJ hydraulic counterblow hammer from China Ji’nan Foundry and Metalforming Machinery Research Institute.
On the basis of the type CHK PLC fully-hydraulic die forging hammer, Baixie absorbed the advanced technique of large size forging hammer from in and abroad. The CDK PLC hydraulic counterblow hammer with unique and up-to-date design has taken the advantage of hi-tech fully hydraulic drive system, striking system with U-shape high rigidity casting steel framework and PLC strike control system.

Regarding free forging hammer , it is flexible for the randomness of forging process requirement and also frequent to change strokes between different blanks and change energy between different working steps, on the contrary, the requirement of speedy returning without time delay and striking frequency are lower compared with die forging hammer, furthermore, the other advantage is the return positioning of the hydro-pneumatic hammer working in oil-discharge easy to be controlled. Since there is no die and not strong rigidity requirement, it is ideal to install the hydraulic-pnumatic power head which working in oil-discharge striking in the free forging hammer.
Regarding the hydro-pneumatic hammer working in oil-discharge striking, the compressed air is filled in the no-piston-rod chamber of the working cylinder, when oil is entered into the piston-rod chamber, the air in the no-piston-rod chamber is compressed and the hammer head is forced to move up, as the piston-rod chamber is connected with the oil return outlet for discharge, the compressed air in the no-piston-rod chamber is expanded and the hammer head will be dropped down at a fast speed under the action of both gravity and expanded compressed air.
