Ireland tension cylinder

(Ireland tension cylinder,produced by Hebei Hengyu company)

tension cylinder are widely used in Ireland,because of clever hydraulic energy conversion,powerful torque,high work efficiency.So our company has designed tension cylinder for customers from Ireland.

Introduction to tension cylinder:

Piston tension cylinder is widely used in hydraulic transmission. When the tension cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the tension cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the tension cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Repair method of small range wear of oil tension cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

tension cylinder is the most important part of construction machinery, the traditional processing method is: broaching tension cylinder block - fine boring tension cylinder block - grinding tension cylinder block. The rolling method is: broaching tension cylinder block - fine boring tension cylinder block - rolling tension cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tension cylinder block is about 1-2 days, rolling 1 meter of the tension 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 tension cylinder increases by 25%. If the tension 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 tension cylinders, you must take the rolling production process. After the tension 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.

If it is found that the tension cylinder lubrication is poor or the tension cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the tension cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the tension cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the tension cylinder center line. In this way, when the piston works in the tension cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the tension cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about tension cylinder:

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
