Description
Technical field
The utility model relates to a kind of swan neck system, particularly a kind of PVDF engineering plastics pipe hot air circulation swan neck system that is applied to.
Background technology
In various workers' usefulness, civil building and electric equipment, be extensive use of plastic pipe, especially the PVDF engineering plastics pipe of various diameters, be used for upper and lower conduit and blast pipe, cable penetration pipe etc.Send out trend according to pipeline, tube bending must be become suitable angle.Used pipe bender adopts supporters such as the spring steel wire of fit diameter, rubber bar is penetrated in the pvc pipe, or with sandstone as filler, on heater, be heated, then, form by required angular bend.Present heater is to be placed on when being heated to flexible temperature on the electric furnace mostly, on default jig or manual bending during to angle of setting and radian, is cooled to room temperature, with rubber spring steel wire, glue rod or pull out from pipe, finishes the bend pipe operation.Heat owing to adopt on the electric furnace, the tube bending place easily produces distortion on the one hand, diminishes, narrows down as wrinkling, footpath, pass, cause draining, exhaust freely not to reach threading and be restricted easily, on the other hand, complex procedures, efficient is low, make and sandstone as filler inconvenient operation especially.
Summary of the invention
The object of the present invention is to provide a kind of PVDF of being applied to engineering plastics pipe hot air circulation swan neck system, can make heating of PVDF engineering plastics pipe and crooked one-shot forming by this swan neck system, operation is simple, the efficient height, and make the pipe that processes indeformable, wrinkle resistant.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of PVDF engineering plastics pipe hot air circulation swan neck system that is applied to, it is characterized in that this swan neck system comprises a baking oven, bend pipe mould is housed in the baking oven, bend pipe mould is connected with frequency conversion brake motor shaft, and can the mould heating pipe built-in be installed in the described bend pipe mould with brake motor shaft rotation of frequency conversion, be provided with the circulation air path that communicates with baking oven in the baking oven, circulation air path is connected with a circulating fan, and electric heating tube is installed in the circulation air path.
As the utility model improvement of the technical scheme, the baking oven inwall is provided with thermal insulation layer.
As the utility model further improvement in the technical proposal, baking oven is equipped with positioning cylinder, and locating piece is installed in the baking oven, and positioning cylinder is connected with locating piece.
Further improvement as the utility model technique scheme is equipped with the cooling blower that is connected with baking oven on the baking oven.
The beneficial effects of the utility model are: the utility model allows pipeline softening by circulating air equably, and mould is together with the pipeline rotational forming, and through insulation, cooling, operation is simple, the efficient height, and make the pipe that processes indeformable, wrinkle resistant; Baking oven has been installed the mould heating pipe built-in, and makes hot air circulation by circulating fan, realizes the heating function of circulated air, forces to improve the circulated air temperature, makes the circulated air temperature meet the bend pipe requirement, thereby temperature is even in the control baking oven; Mould is built in the baking oven, directly bends moulding in baking oven, not influenced by external factor; Frequency conversion brake motor can be controlled bending process rate by pipeline, and near bending when finishing, slowly bend pipe speed is so that motor brakes, with control curvature arc size accurately; Temperature thermocouple and mould heating pipe built-in are installed on the mould, can be independently heated, prevent that pipeline and mould from existing temperature difference to cause pipeline and mould contact surface to produce heat loss the baking oven inner mold; Baking oven is connected with cooling blower, and cooling blower quickens cooling to bend, to enhance productivity; The location cylinder can prevent the pipeline resilience.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
