Abstract
The utility model relates to a plastic pipe bending apparatus, belonging to the field of shaped material processing. The apparatus solves the problems that the existing processing method causes a plastic pipe to be wrinkled on a bending position, deformed, even damaged, etc. The apparatus adopts a solid cylindrical pipe core filler. A bending pipe which is processed by the apparatus is smooth on surface, indeformable, beautiful and durable. The utility model has a simple and practical operating method, and obviously improves work efficiency and the rate of finished products. The utility model can be widely used for bending water charging and discharging pipes with various pipe diameters, exhaust pipes, cable penetrating pipes, etc. in industrial and civil buildings and electrical equipment.
Description
The utility model relates to a kind of swan neck system, belongs to shape material manufacture field.
In various workers' usefulness, civil building and electric equipment, be extensive use of plastic pipe, especially the PVC plastic tube of various diameters, be used for upper and lower conduit and blast pipe, cable penetration pipe etc.According to the trend of pipeline, tube bending must be become suitable angle.Used pipe bender adopt the spring steel wire with fit diameter to penetrate in the pvc pipe or with sandstone as filler, on heater, be heated, form by required angular bend.Because the spring steel wire outer surface is rough, make the tube bending place easily produce distortion, as wrinkling, caliber diminishes, narrow down, cause draining, exhaust freely not to reach the threading capacity and be restricted; Use sandstone to make filler and then operate inconvenience, the problem of distortion is arranged equally.As be out of shape seriously, then causing the pipe subscription rate, the processed finished products rate is lower.
This device has overcome the deficiency of above-mentioned pipe bender, makes the pipe that processes indeformable, wrinkle resistant, and a kind of simple and practical swan neck system is provided.
This device is made of bend pipe jig, heater, tube core filler etc., it is characterized in that the tube core filler is shaped as solid garden cylindricality.
The used tube core filler of this device is the vacuum rubber rod.
According to the difference of caliber, employing cooperates the rubber bar of caliber as the tube core filler, is generally less than caliber 2mm, and the length of rubber bar can be determined according to the size of caliber and required bent angle orphan degree, gets conveniently to satisfy lonely length and dress.Concrete procedure of processing is, the rubber bar that cooperates caliber packed into needs crooked position in the plastic tube, when making it on heater, be heated to flexible temperature, it is bent to predetermined angle, stop heating, when being cooled to room temperature rapidly, rubber bar is pulled out from pipe, promptly finished bend pipe processing.
Operation is simple for this device, and the bend pipe surfaces externally and internally that processes is smooth, attractive and durable, and knee caliber and straight tube place are basic identical, do not influence extraction flow and threading capacity, and yield rate can reach 100%; Rubber bar is reusable, and cost is low than additive method, the working (machining) efficiency height.
Fig. 1 is rubber bar and a plastic tube assembling back elbow schematic diagram in the swan neck system.
Embodiment:
With external diameter is that Φ 40mm, wall thickness are that the pvc pipe bending of 2mm is angled 90 degree, lonely degree is the bend pipe of R 〉=50mm.Earlier be that the vacuum rubber rod 1 of Φ 34mm, the length 〉=1000mm pvc pipe 2 of packing into needs knees with diameter, when this position is heated to flexible temperature on electric furnace, on default jig or manual bending when spending to above-mentioned angle and orphan, be cooled to room temperature rapidly, rubber bar is pulled out from pipe, promptly finish the bend pipe operation.
Claims (2)
1. a plastic tube swan neck system is made of bend pipe jig, heater, tube core filler etc., it is characterized in that the tube core filler is shaped as solid garden cylindricality.
2. swan neck system according to claim 1 is characterized in that described tube core filler is the vacuum rubber rod.
