Follow-up control fully hydraulic open die forging hammer is a kind of electric-hydraulic hammer operated by follow-up valve and drove by fully hydraulic driving system. The lower chamber of its cylinder is connected to high pressure oil always, and follow-up valve controls the upper chamber oil in and out to realize striking and return. When upper chamber connecting to high pressure oil, it will drive cylinder to get pressure difference and with ram gravity to realize quick striking; when oil discharging from upper chamber, oil will act on circle area of lower chamber and conquer ram gravity and relevant friction force to realize return.
Advantages
Its principle decides its advantages, as bellow:
1) Avoid oil and gas mixing, and air leakage;
2) When return, there is no back pressure in upper chamber, so return is fast and with high striking frequency;
3) Upper and lower between piston, there are both hydraulic oil, so the sealing working environment is improved a lot and extend its life;
4) Lower chamber is connecting to high pressure always, so the ram can return at once after striking and short die contacting time;
5) Hydraulic system pressure is stable, so it is easy to realize striking energy precise control.
6) Such hammer is a kind hammer that can instead of hydra-pneumatic hammer with its advantages, such as simple structure and lower malfunction.
Structure and performance features:
It fully refers to successful experience of China hydra-pneumatic hammer, and surpassed it on structure, safety, easily of maintenance, as bellow:
1. hydraulic driving system structure
1) there are only main cylinder and accumulator on driving system, and tie plate inner is no need anti-high pressure welding, its structure is simple and reliable;
2) there is not adding air system and auxiliary air system, so its structure is simpler; and main system is connected by pre-stressed bolts to improve connecting reliability;
3) accumulator is moving down whole and supported on waist part to improve its stabil |
