Regarding 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 CDK counterblow hammer 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 70s,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 80s 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 striking control system.
The structure characteristic:
U-shape high rigidity casting-steel framework and adjustable actinoid wide guide construction are used in CDK hydraulic counterblow hammer, on which the one side guide clearance can be accurate to 0.1mm.Especially.it is suitable for precise forging. The hammer tup and the framework will strike each other with equal energy, even if the stroke and speed of the framework are different. The frame is much heavier than the tup and the ratio is up to 10:1, which ensures the stability when striking. There are several anti-vibration pad filled in compressed air under the lower anvil. When the framework is hydraulically forced down, it is also compressing the air in the anti-vibration pad. As releasing the hydraulic pressure, the whole framework is lifted up by the compressed air at the same time, the upper hammer head is driven down by high pressure oil and strike together for the purpose of forging operation.
The hydraulic drive system makes use of separate side-set design, concentrated control and all the pipelines connected with flexible tube, which completely solves the reliable influence on the hydraulic system when hammer working.
CDK PLC striking control system takes the advantage of touch screen and programme logic controller. With the touch screen, we can realize man-machine conversation and display the statue of working and malfunctions. With the PLC, we can control the striking energy and programme.
Performance and feature:
A. High energy-saving
The CDK hydraulic forging hammer is actuated by hydraulic drive system, which makes the energy utilization to 65% and the striking efficiency to 95%.However, the traditional hammer only has the 2-3% energy utilization and 85% striking frequency. Furthermore, the energy-saving is precisely on controlling striking energy and it is wasteful to give more.
B .High accuracy
U-shape high rigidity framework and adjustable actinoid wide guide are the precondition for accurate forging. The precisely control of striking energy and programme can avoid the unstable quality due to different operator.
C. Less or no vibration
The forging hammer tup of CDK and framework will strike each other with equal energy. There are several anti-vibration pad filled in compress air under the framework. The forging hammer will not impact foundation when striking; therefore, the entire impact vibration problem can be solved. CDK PLC hydraulic counterblow hammer is significant modern equipment ,which can meet the environmental needs.
D. Fewer investment
CDK PLC hydraulic hammer not only has a price advantage with higher performance, but also can economize the basal investment of vibration isolation and reduce the demand of workshop. It is calculated that compared with the same weight electro-hydraulic hammer, the cost of the counterblow hammer can be reduced 1/3 only on equipment and basal foundation.If including the new workshop, the reduction can up to 50%.
E. Lower using cost
The advanced CDK hydraulic forging hammer are not only on high efficiency, energy-saving, high precision, no vibration and environment protecting but also striking energy control. Giving the forgings enough energy but not more can lessen the vibration, reduce the noise, greatly improve the reliability of the equipment and extend the die life.
