The Philippines hinge shaft cylinder

(The Philippines hinge shaft cylinder,produced by Hengyu Group)

hinge shaft cylinder are widely used in The Philippines,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed hinge shaft cylinder for customers from The Philippines.

Introduction to hinge shaft cylinder:

When producing oil hinge shaft cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular hinge shaft cylinder action. Troubleshooting method: Replace the rubber hose.

hinge shaft cylinder is the most important part of construction machinery, the traditional processing method is: broaching hinge shaft cylinder block - fine boring hinge shaft cylinder block - grinding hinge shaft cylinder block. The rolling method is: broaching hinge shaft cylinder block - fine boring hinge shaft cylinder block - rolling hinge shaft cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the hinge shaft cylinder block is about 1-2 days, rolling 1 meter of the hinge shaft cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the hinge shaft cylinder increases by 25%. If the hinge shaft cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality hinge shaft cylinders, you must take the rolling production process. After the hinge shaft cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

When the hinge shaft cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the hinge shaft cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

Answers to some questions about hinge shaft cylinder:

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.

Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.
