The decorative film production forming treatment process comprises the following steps: S1, feeding: raw materials are input into a feeding box above the front end of the rack of a calender, crushed by a crushing roller and heated and melted; S2, calendering: the melted raw materials enter between two horizontal calender rollers on the upper side of the front end of the rack, are extruded by the two horizontal calender rollers, form sheet films, then pass through two vertical calender rollers on the lower side in sequence, and form required decorative film sheets under the extrusion and extension of the calender rollers; the speed of the delayed cooling water backflow can be realized, meanwhile, the fan blades on the backflow pipe are driven to rotate, thereby ventilating the passing decorative films, and the combination of air cooling and water cooling is used to improve the effect of the cooling and forming of the decorative films; the cut-off excess edges can be conveyed into the feeding box to be mixed, crushed, heated and melted with the raw materials and then reused.

Variable-diameter flaring forming die for seamless steel pipe
ActiveCN224101661UHave a cooling effectImprove cooling effectShaping toolsCleaning using toolsWater storageCooling effect
The utility model belongs to the technical field of seamless steel pipe machining, and particularly relates to a seamless steel pipe variable-diameter flaring forming die which comprises a flaring forming die body. An outer shell is arranged on the side wall of the flaring forming die body. A driving motor is fixedly connected to the inner side wall of the outer shell; the fan blades are driven by the driving motor to rotate and generate certain airflow, finally, the airflow is blown out of the outside through the first air outlet holes, part of heat in the airflow can be absorbed through the heat absorption plate, the heat absorbed by the heat absorption plate is cooled through water, and therefore the fan blades can blow out cold air, the cooling effect can be achieved during seamless steel pipe machining, and the service life of the seamless steel pipe is prolonged. And meanwhile, the water storage box and the heat absorption plate are used for enabling the fan blades to blow out cold air, the cooling speed of the seamless steel pipe and the flaring forming die body can be further increased, the cooling effect is improved, the service life of the flaring forming die body is prolonged, and influences on the organization structure and performance of the seamless steel pipe are reduced.
