Development and innovation of modern forging hammer technology (III)

⑴ It can realize precise control of strike energy

by accurately controlling the closing time of the strike valve, the program-controlled hammer not only ensures the energy required by the forging, but also does not produce additional impact kinetic energy. Therefore, the service life of some key parts such as hammer rod, hammer head and upper and lower dies is greatly improved

⑵. The return journey is fast

because the lower chamber of the main oil cylinder is always connected with the accumulator, once the upper chamber is relieved, the hammer can be lifted quickly, so the contact time of the die is short. This performance, combined with accurate energy control, can increase the service life of the forging die by more than one time

⑶. High forging precision:

because the guide rail of this product adopts X-shaped structure, the guide rail gap can be adjusted very small, and the forging precision is very high

⑷. The material utilization rate is very high

because the energy can be controlled, the blank making accuracy is very high, and the flash of the forged piece is only 25% of the wall thickness of the previous generation of connectors. Because of the high forging accuracy, the upper and lower dies will not be wrong, so the material utilization rate is very high, laying the foundation for less and no cutting. 6. Workbench stroke: 0 400mm

⑸. Low noise

because the product is a programmable equipment with striking energy, the program is compiled to make the forgings complete, but not give more residual energy, so the noise is very small. The operator of the traditional forging hammer judges whether the forging is finished by listening to the sound of the die. Sometimes the judgment is not accurate, and he is used to hitting a few more times, which is actually redundant

⑹. No bumping phenomenon

through accurate calculation and design of the size of the damping hole and orifice in the hydraulic system, the hammer head is cushioned to the top, which is very stable, without any bumping phenomenon

⑺. Low vibration

because the strike energy of this product can be programmed, no excess energy is generated, and the lower part of the hammer body is equipped with a vibration isolator of the brand of jieergu produced by German technology, which has no impact on the surrounding machine tools and residential areas

⑻. Environmental protection:

this product is an environmental protection product because of its low impact noise, shock absorber and low vibration during the strike process

⑼. The quality of forgings is relatively stable

due to the control of the program controller, the forging processes of various forgings can be stored in the program and adjusted for use at any time according to needs. Therefore, the same kind of forgings can get consistent strike energy and strike times, avoiding the diversity of manual operations, so the quality of forgings is relatively stable

IV. manual full hydraulic die forging hammer

1. Principle: take the S-type sensor as an example

the basic principle of manual full hydraulic die forging hammer is that it adopts the transmission of oil pump accumulator, and controls four large diameter cartridge valves through a manual slide valve to realize the actions of lifting hammer, hanging hammer, slow lowering, striking, etc

2. Advantages and disadvantages compared with program-controlled hammer:


⑴ The operating mechanism can be operated manually or by foot. The energy is achieved by the operator controlling the stroke of the hammer head, and the operation is relatively flexible. ⑵. Simple structure and convenient maintenance


⑴ Energy can not be accurately controlled, so it is difficult to achieve precision forging; ⑵. Because the oil pressure is smaller than the program-controlled hammer, the stroke is longer, the strike frequency is smaller, and the production efficiency is low
