A choice between self-compensating and adjustable shock absorber

The industrial shock absorbers from HOILD top off the company's offerings in damping technology. This HOILD category gives designers a choice between self-compensating and adjustable shock absorber. Whichever design is chosen, this type of shock absorber impresses with its robustness and operational readiness wherever heavy loads need to be reliably stopped on-the-spot and at a precise point. 

Shock absorber for heavy duty

Whether in state-of-the-art cranes, automated high-rack facilities or in the container logistics, whether as bump stop for trains, cable cars or swing bridges or to decelerate slabs and supports in steelworks: Heavy duty shock absorber are used in many different industrial areas to protect machines, equipment and goods from heavy impacts.

The main purpose of the hydraulic shock absorber series

Strictly speaking, the higher precision of the speed governor, oil filled shock absorbers and oil head, etc. belong to the same type, the focus is used in the high degree of automation of mechanical equipment, the main role is to buffer and Stable speed, so that machinery and equipment to a certain speed uniform speed, and thus ensure the accuracy of mechanical equipment and safety characteristics, to a large extent to enhance the operational efficiency of machinery and equipment.

Hydraulic shock absorber of precision speed controller with the characteristics

Hydraulic shock absorber of precision speed controller with the characteristics:

1, the piston lever friction is relatively small, basically can be considered that there is no friction

2, precision governor for a long time without the use of oil leakage situation;

3, stable characteristics of strong, can continue for a long time stable braking;

4, precision transmission is the use of permanent lubricants, long-term use do not need to add lubricant.

Precision speed stabilizer to ensure that the operation of machinery and equipment when the speed is stable, to ensure that its degree of automation and precision, so that the quality of parts has improved.

Adjustable Pressure in Hydraulic Shock Dampers

The ability to adjust pressure in a damper will make it one of the more versatile tools in any heavy gauge stamping situation. Being able to change the tonnage in your press in just a few minutes saves on down time and tooling. It also allows the dampers to be used on a different size presses (smaller) if needed. This makes the dampers useful life much greater because it can be used across a number presses over time. External pressure adjustment is a unique quality of damper and no other competitor in the market has this feature.To change the pressure in a hydraulic oil shock absorber all you’ll need is a 3/16th Hex Head and pressure gauge. Then you’ll need to locate the flow control valve and use the wrench to adjust the pressure up (rotating in clockwise) or down (rotating it counter-clockwise). It’s really that simple. The adjustable hydraulic damper will start to optimize the performance of any press and it will not add additional forward tonnage to any blanking application. It will also Increase production by running at a reduced pressure will allow the press to run at higher SPM without excessive wear.

How does hydraulic shock absorber work?

Blanking requires the press to build tonnage that exceeds the shear strength of the material. When this happens, the press frame and housings are loaded in tension. At the moment of material fracture, the resisting forces in the press are released and the press slide is allowed to accelerate downward at speeds that approach 10g's.Sides and adjusted properly, the hydraulic shock absorber will automatically develop a resisting counter pressure force (through internal hydraulic pressure control) that will absorb the acceleration and eliminate the resulting shock and vibration.

Who Needs Shock Dampers?

Custom oil shock damper is beneficial in any blanking, punching of die trimming application of metal, plastics of composites that is experiencing excessive reverse shock, premature die wear, fatigued press components or hydraulic system failure at part breakthrough.
