Rubber machinery edit
It is a machine used to manufacture various rubber products such as tires, including general rubber machinery, tire machinery and other rubber product machinery.
General rubber machinery is the machinery for preparing rubber or semi-finished products, including raw material processing machinery, rubber mixing machine, extruder, calender, curtain canvas pretreatment device and cutting machine.
Rubber mixing machine is divided into open type and closed type. The open rubber mixing machine is mainly used for hot refining, sheeting, breaking, plasticizing and mixing of rubber one thousand eight hundred and twenty-six It has been used in production since, its structure is relatively simple, and it is still widely used in modern times; The closed rubber mixing machine is mainly used for plastic mixing and mixing of rubber. It has an internal mixing room more than the open rubber mixing machine. since one thousand nine hundred and sixteen Since the invention of the closed rubber mixer with elliptical rotors in, the closed rubber mixer has developed rapidly in the rubber industry, and later there were other forms of closed rubber mixers with rotors. The mixing cycle of modern closed rubber mixing machine is two point five ～ three Minutes, the larger capacity of the internal mixing room is up to six hundred and fifty Litres.
Extruder is a rubber machine used to extrude tread, inner tube, rubber tube and various rubber strips. It is also used to cover cable and wire products. A common type of extruder is a screw extruder. When it is working, the rubber material is stirred, mixed, plasticized and compacted in the barrel by virtue of the rotation of the extrusion screw, and then moves towards the head, later extruding products of a certain shape from the die.
The calender is mainly used for gluing or rubbing of curtain canvas, pressing, fitting, molding and embossing of rubber materials. Next to the front desk calender one thousand eight hundred and fifty-seven It was made in and used in production, and has been continuously improved since then. Especially in the 20th century fifty Since the s, the development of plastic industry has effectively promoted the improvement of high-precision and high-speed calenders.
Tire machinery includes tire molding machine, tire bead machine, tire molding vulcanizer, capsule vulcanizer, cushion belt vulcanizer, inner tube joint machine and inner tube vulcanizer, as well as bicycle tire machinery, tire repair machinery and rubber renewal production machinery. world 60% The above rubber is used to make tires, so tire machinery plays an important role in rubber machinery.
The tire molding machine is mainly used to fit and process various parts such as rubber cord, bead, tread, etc. into tire blanks. According to different uses, it can be divided into two categories: ordinary tire molding machine and radial tire molding machine. The whole process of radial tire molding is completed by one molding machine, which is called one-step molding method; The carcass is made by a modified ordinary tire molding machine and then molded on the radial tire molding machine, which is called two-stage molding method.
The tire curing press is a machine used for vulcanizing the outer tires of pneumatic tires, such as automobiles, engineering vehicles, tractors and aircraft. This machine appeared in the 20th century forty Age. The tire loading, molding, vulcanization, tire unloading, post inflation cooling and other operations can be completed on the molding vulcanizing machine. The temperature, pressure and steam chamber temperature of the superheated water in the capsule can be measured, recorded and controlled, and the entire production process can be carried out automatically.
