CTK Fully Hydraulic Die Forging Hammer

Performance and Feature：

Flexibility and speed are main technological features of forging hammer being used. It is possible for the hammer tup to obtain huge energy in short stroke due to its fully hydraulic driving system, that is, high speed forging in the short stroke and high frequency continuous forging are the reality, which is precondition for fast forming of the forging parts. This is the unique advantage of PLC fully-hydraulic die forging hammer over any other forging equipment.

Energy-saving is the main cause for hydraulic hammer having been developed up to now, PLC fully-hydraulic die forging hammer can reach 65% drive efficiency, over 30 times more efficient than other traditional steam hammer with only 2% energy utilization. The result of energy saving is substantial.

U-shape casting steel frame, easily dismounting wide guides as well as good die alignment and adjustment structure guarantee forgings forming with high accuracy. The guide clearance is 0.2mm, and working accuracy, striking rigidity, striking efficiency and accuracy hold facility are more favorable than steam hammer.

The noise of forging hammer is unavoidable but can be reduced. If the striking energy is enough, the forging will be formed without many strikes. Or if the striking energy can be controlled to give just necessary but not more, the situation will be different.

Traditionally, the striking energy is not adjustable and usually much more than really needed. Also the operator is accustomed to strike more times, in fact, which are waste. As far as Baixie fully hydraulic hammer is concerned , it can precisely control the striking energy and each striking can be preset according to designed program which control striking energy and striking sequence , therefore, no surplus energy is waste and noise is reduced accordingly.

In order to overcome the big vibration of hammer with anvil, fully hydraulic hammer used the hydraulic damping vibration system produced by German GERB Corporation with 90 years history. It not only has isolated to the near engine, the building and inhabitant’s vibration influence, but also reduced the affect on the equipment reliability and the service life brought by hammer.

The vibration question has been considered when forging hammer is designed, such as no thread fastener as far as possible. The die is fixed with the wedge in the die holder, which makes vibrate cannot affect equipment itself, and the power head used the flexible joint and so on to reduce and omit the vibration.

When the forging hammer is operated manually, no matter how skilled the operator is, who can not guarantee keeping same for each forgings. Especially to the shift-change, it’s more difficult to keep constant striking energy and striking numbers for the same forging. But Baixie fully hydraulic hammer is able to keep the same forging procedure by using PLC, even if operated by different workers. For some special forgings, the forging procedure can be pre-programmed and digitally stored by PLC, and will be re-used for the same forging late.

Energy-saving not only means high driving efficiency but precise energy control to avoid unnecessary energy consumption ,which will also influence lives of forging hammer and forging die because of absorbing surplus energy.

It is easy to explain how big the parts can be forged on the forging machine by an operator, while it is difficult to forging hammer. The outstanding advantages of a forging hammer are fast striking speed and high striking frequency, which is most suitable for those forgings needing many times strike and fast speed deformation to fill in the die impression. Due to fast forging speed and short die contact time, it is suitable to forge thin and light and cooling-fast forgings and good for die life. When forging these kinds of forgings with complex shape and weight tolerance requirement, the forging hammer’s performance and economic advantages are very obvious.

The forging hammer is the best equipment for forging industry and very suitable for production in small batch with various shapes.

It is obvious economically to convert old steam-air hammer into hydraulic power tup and much cheaper than buying a new fully-hydraulic die forging hammer. Regardless of hammer power, steam-air hammer is much cheaper than fully-hydraulic hammer. But as a matter of fact, the driving system of the hammer must be taken into consideration, in this way; the cost between them is almost the same.

The main features of Baixie fully hydraulic hammer are unique design and reliable safety. By using three standard hydraulic priority valves, Baixie fully hydraulic hammer can realize oil filling, oil discharge, adjustment and striking operations with easy and fast and cheap maintenance and convenient change-work etc.

The fully hydraulic hammer can monitor oil cleanness, temperature, pressure and level by sensors, and will alarm immediately as long as something wrong happens and then automatically diagnose and protect itself by stopping the forging or even the hammer. Meanwhile, this sensor system can also monitor other safety auxiliaries in order to let the hammer can be operated with suitable conditions.

In order to be convenient for the users to service and maintenance easier and faster, the normal troubles can be shown on the screen. If there is something wrong, it is quick to find the trouble and solve it at once to shorten the downtime.
