The heat exchanger pipeline is used for guaranteeing that the temperature of compressed air in the high pressure air cylinder fluctuates within a controllable range in repeated reciprocating motions. By means of the controllable air energy storage type buffer, impact kinetic energy is converted into gas potential energy and internal energy to be accumulated, and the gas potential energy and the internal energy can be released when needing, restoration of the piston rod can be achieved. The pressure of gas filled in the high pressure air cylinder is controllable, thereby guaranteeing formed buffer to reach the largest stroke of the piston rod of the low pressure air cylinder and obtaining relatively stable buffer process. The potential energy of the compressed air in the high pressure air cylinder is utilized when the controllable air energy storage type buffer resets so that other modes similar to spring resetting do not exist. Therefore, no fatigue property of the controllable air energy storage type buffer is required to be considered, and the controllable air energy storage type buffer can be applied to occasions having high frequency impact and effectively guarantees production safety.

Damping device is to prevent that machinery from rigid collision a kind of safety installations commonly used taking place in running; Its function mainly is to play buffer function at the movement travel terminal; Prolong the action time of impulsive load, absorb and transform the kinergety of impulsive load, thereby reduce the harmful effect that mechanical shock causes equipment as far as possible; Just be widely used at present, mainly be used in the various middle-size and small-size industrial machinery safety system that impact force is less, striking velocity is slower.
The modern heavy-duty engineer equipment has characteristics such as impact force is big, speed is fast, and existing damping device can't meet the demands.At present; How to be occupied absolute leading position in state's internal inner ring and the accumulator market by foreign brand name; But be used for the impact of the big mass motion object of absorption rate≤5 m/s more; In a single day the quality of object and movement velocity change just needs type selecting, purchase and installation again, and majority all is to use mechanical self-locking device in the buffer product, and damper piston need be opened the self-locking device completion by external force and reset; For the repeated stock of the medium and small quality of large scale industry machinery, high-speed moving object, the existing market product all can't be accomplished effectively buffering and accumulation of energy basically.
The model utility content
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the existing technology; And a kind of controllable gas spring buffer is provided, and be a kind of more high performance damping device, can tackle the repeated stock of little quality and high-speed moving object; To prevent that machinery from rigid collision taking place in running; Effectively reduce the influence that heavy equipment brings when shock and vibration, improve the security and stability of modern heavy-duty engineer equipment, ensure production safety.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of controllable gas spring buffer; Comprise high pressure cylinder that uses as accumulator and the low-pressure cylinder of carrying out buffer function; Between high pressure cylinder and the low-pressure cylinder valve ending cover is set; It is characterized in that piston and piston rod are set in the low-pressure cylinder cylinder body, high pressure cylinder only is made up of the high pressure cylinder cylinder body, and high pressure cylinder is used to store and is compressed pressurized gas in the low-pressure cylinder; Simultaneously in the high pressure cylinder heat exchange manifold is housed, can ensures that controlled spring buffer pressurized gas temperature in to-and-fro motion mesohigh cylinder repeatedly fluctuates in controlled range.
The described valve ending cover of the utility model is provided with low paramount valve and high extremely low valve.
Be provided with monitoring module in the utility model high pressure cylinder, the high pressure cylinder cylinder body is provided with gas ducting and disappointing pipeline.
On the utility model piston magnet ring is housed, low-pressure cylinder cylinder body arranged outside has Test coil, carries out piston rod position and detects.
Be provided with cushion pad in the cylinder in the utility model low-pressure cylinder cylinder body, the low-pressure cylinder cylinder cap is provided with the outer cushion pad of cylinder.
The beneficial effect of the utility model is: through regulating the inflation pressure of controllable gas spring buffer high pressure cylinder; Can tackle the high speed impact of quality from speed≤70 m/s of several kilograms to several tons object; Impact kinetic energy is converted into the potential energy of gas and interiorly can carry out accumulation of energy; The moment at needs slowly discharges, and accomplishes resetting of controllable gas spring buffer piston rod.Because inflation pressure is adjustable in the high pressure cylinder, when the object of reply different quality and movement velocity impacts, can guarantee to cushion the range that formation reaches the low-pressure cylinder inner piston rod, buffering course is steady relatively.What use when the controllable gas spring buffer resets is the potential energy of pressurized gas in the high pressure cylinder, does not exist spring-like to reset and waits other pattern, therefore need not consider its fatigue characteristic, can be used for having the occasion of high frequency time impact, effectively ensures production safety.
