introduction： With the increasing development of the automobile industry，The number and variety of car stringers are also increasing，Longitudinal beam processing equipment is also constantly innovated and improved，Therefore, the reasonable selection of longitudinal beam processing equipment is the key for automobile longitudinal beam manufacturing enterprises to maintain strong competitiveness。 A general longitudinal beam consists of a main beam and a reinforced beam，The shape of the beam isUtype。The reinforcing beam is installed in the main beam，rivet。Depending on the vehicle type，The longitudinal beam is divided into straight beam and curved beam；It is also divided into beam of equal section and beam of variable section。 one、Processing procedure of longitudinal beam General processing processes are divided into two categories，That is, the hole is processed before forming or the hole is processed after forming。

introduction： Working principle： The movement of solid materials in the fluidized bed is mainly carried out by vibration。Vibrating fluidized beds can be used for drying or cooling processes，Suitable for coarse particles or irregular particles and not easy to flow products，Or products that require lower fluidization rates and are easy to bond because the particles are to remain intact、Temperature sensitive products。The particle layer is generally not exceeded when using this device200Millimeter thickness，Therefore, the particle retention time per unit area is much less than that of the non-vibrating bed，The thickness of the particle layer in the non-vibrating fluidized bed can be as high as1500millimeter。

introduction：What kinds of plastics can be divided into What are its characteristics？ According to the molecular structure and thermal properties of synthetic resin in plastics．Plastic plastic resin4Kind of，One is thermoplastic，The other is thermosetting plastics。 [1)Characteristics of thermoplastics 1)The molecule of resin has a linear or chain structure。 2)Soften on heat，When it reaches a certain humidity, it is molten，Become a fluid, sticky bunker，It can be formed into a certain shape under a certain pressure，After cooling, it retains its formed shape。It can be softened if reheated、Incipient melting，Repeated forming。 3)On the heat、Only physical changes occur during the cooling forming process

introduction： Abrasive tools are used for grinding、Grinding and polishing tools。Most abrasives are artificial abrasives made of abrasives and binders，Also useful natural mineral rock directly processed into natural abrasive tools。 Abrasive tools are classified according to their source of raw materials，There are two types of natural abrasives and artificial abrasives。The only natural abrasives commonly used in the machinery industry are oil stones。Artificial abrasives are distinguished according to basic shape and structural characteristics，Grinding wheel、Grinding head、Oil stone，Sand tile and coated abrasives five categories。In addition，It is also customary to list abrasive as a class of abrasive tools。 Abrasives are widely used in machine building and other metal processing industries，
