Cold-drawn seamless tube is a kind of steel processed by cold-drawing and other techniques under normal temperature environment. Compared with the cold-drawn tube, the hot-rolled tube is a kind of steel processed above the recrystallization temperature. The specific differences between cold-rolled tubes and hot-rolled tubes are as follows: 1) When making a cold-drawn pipe, its … Read more
Cold-drawn steel tubes are precision cold-drawn seamless tubes with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality. What are the classifications of cold-drawn tubes？ … Read more
Honed tubing is seamless cold drawn steel tubing that have been honed. Honing is a machining process. The inner hole of the cold-drawn steel tube is reciprocating high-speed grinding through the honing head, so that the inner hole can meet the required tolerance size and surface roughness requirements for the hydraulic cylinder barrels. Compared with … Read more
Main feature of seamless steel pipe Seamless steel tube has no welded seams and can withstand higher pressure. Products can be with rough surfaces as-cast or cold drawn. Precision steel pipe is a product that has appeared in recent years, mainly because the inner hole and outer wall have strict tolerances and roughness. Features of … Read more
What material is used for the hydraulic cylinder barrel? As the main component of the hydraulic cylinder, the processing quality of the hydraulic cylinder barrel directly affects the life and reliability of the entire product. The cylinder has high processing requirements, and its inner surface roughness is required to be Ra0.4 ~ 0.8um, and the … Read more
What are the characteristics of the honing tube heat treatment process? The heat treatment process of the honed tube is a heat treatment method for heating and cooling the surface of the iron casting, thereby changing the surface properties of the metal material. The characteristics of the surface heat treatment process are as follows: 1. … Read more
The heat treatment of the honed tube is a very important process. After heat treatment, it can obtain better performance. Let’s introduce the heat treatment process of honing tubes, including the following steps: forging annealing, rough machining, quenching and tempering, semi-finishing, stress relief, rough grinding, high-frequency quenching, tempering, and finishing. The following focuses on two … Read more
The hydraulic cylinder barrel is the main body of the hydraulic cylinder, it is also known as honed tubing. and its inner hole is generally manufactured by precision machining processes such as boring, reaming, rolling or honing, so that the piston and its seals and supports can slide smoothly, thereby ensuring the sealing effect and … Read more
Large-scale hydraulic cylinders are divided into two categories: large-bore large-scale hydraulic cylinders and large-tonnage large-scale hydraulic cylinders. They are characterized by large cylinder diameters, long strokes (individually), large volumes, and large own weights. The pulling force or thrust provided is also large. It is difficult and expensive to process large hydraulic presses. Therefore, before designing … Read more
