Problems solved by technology
Although the above various connection methods achieve the purpose of connection and fixation, the sealing effect is not ideal, and welding and other processes are required to realize the connection, which is not only complicated in process, but may also cause adverse consequences such as deformation of the cylinder body.
[0003] The steel cylinder, the cylinder head and its connecting parts are all made of metal, with a rough surface, heavy weight, and large dimensions. The overall appearance looks monotonous and unattractive, giving people a clumsy feeling

The invention discloses a cylinder body of an oil cylinder and an air cylinder, which is one-step molded by plastics and metals and comprises a cylinder barrel and a back cylinder cover; the cylinder barrel is embedded on the back cylinder cover, and the cylinder barrel, the back cylinder cover, a connecting nozzle and a flange which are arranged on the back cylinder cover are one-step molded together. The manufactured cylinder body has accurate size, good sealing effect, enough strength, rigidity and durability, simplified processing technique, easy manufacture, low cost and high production efficiency. In addition, the cylinder body also can reduce the overall size of a hydraulic cylinder to the great extent, realize compact structure and achieve the effects of beautiful appearance, lightweight and energy conservation.
Description
technical field [0001] The invention relates to a cylinder body of an oil cylinder, in particular to a cylinder body of an oil cylinder formed by plastic and metal at one time. Background technique [0002] In the field of machinery and electronics, oil cylinders have been widely used, including front cover, cylinder barrel, rear cover, piston, piston rod and guide sleeve and other components. Among them, the cylinder barrel and the cylinder head are a part of the oil cylinder, and there are various connection methods. Such as figure 1 It is a structural diagram of a single-piston rod hydraulic cylinder, one end of the cylinder is welded to the rear cover, and the other end is threaded to the front cover. In addition, the connection forms between the cylinder body and the cylinder head include tie rod connection, flange connection, snap ring connection, external thread connection, and internal thread connection. For example, the flange connection of high pressure cylinder...
