5, the specific embodiment
With reference to Figure of description equipment for extruding longitudinal corrugated pipe of the present invention is done following detailed explanation.
As accompanying drawing 1,2, shown in 4, equipment for extruding longitudinal corrugated pipe of the present utility model, its structure is by frame, lowering or hoisting gear 16, external extrusion knives catch bar 5, external extrusion knives 7, internal extrusion knives 8, back taper mandrel 10 is formed, frame is by base 1, lower guide plate 4, last guide plate 11 and column 2 are formed support frame, lowering or hoisting gear 16 is arranged on the base 1, the top of lowering or hoisting gear 16 is provided with draw back plate 3, the limit portion of draw back plate 3 is connected with back taper mandrel 10 lower ends with the lower end of external extrusion knives catch bar 5 respectively with middle, last lower guide plate 11,4 are provided with sliding sleeve 12, the two ends up and down of external extrusion knives catch bar 5 and back taper mandrel 10 are through respectively among the sliding sleeve 12, the middle part of external extrusion knives catch bar 5 is provided with connecting rod 6 and is connected with external extrusion knives 7, the inboard of internal extrusion knives 8 is provided with triangle boss 9, and triangle boss 9 joins with the conical surface of back taper mandrel 10 respectively.
In equipment for extruding longitudinal corrugated pipe, last lower guide plate 11,4 and the interior external extrusion knives face that two ends join about in the of 8,7 are provided with horizontal concrete chute 14,13, and the two ends up and down of interior external extrusion knives 8,7 and horizontal concrete chute 14,13 are slidingly connected.
In equipment for extruding longitudinal corrugated pipe, the centre of last guide plate 11 has circular hole 15, and pipe 17 to be processed passes circular hole 15 and places between external extrusion knives 7 and the internal extrusion knives 8.
In equipment for extruding longitudinal corrugated pipe, the quantity of interior external extrusion knives 8,7 equates that it is two at least that interior external extrusion knives 8,7 is provided with quantity.
In equipment for extruding longitudinal corrugated pipe, lowering or hoisting gear 16 is hydraulic press or screw thread lift.
The operation principle of equipment for extruding longitudinal corrugated pipe of the present invention is, the thin-wall steel tube blank that welding is good is placed between external extrusion knives and the internal extrusion knives, the primer fluid press upwards promotes to move on the draw back plate, draw back plate promotes to move on the external extrusion knives push rod, the external extrusion knives push rod promotes external extrusion knives by connecting rod and pushes thin-wall steel tube to the center, because external extrusion knives and the interlaced arrangement of internal extrusion knives; thin-wall steel tube begins to be the distortion of longitudinal ripple shape under the extruding of interior external extrusion knives; for the two-way extruding of external extrusion knives in preventing causes thin-wall steel tube to break; the back taper mandrel is along with the inside extruding of external extrusion knives moves on synchronously gradually; the triangle boss of the side that internal extrusion knives and back taper mandrel join along the conical surface of back taper mandrel slowly to the slip of the thin portion of the conical surface; make all extrude cutter integral body and shrink; until the triangle blade of the triangle blade of external extrusion knives and internal extrusion knives and connect to the center; and and connect after gap length equate with the girth of thin-wall steel tube that just in time such thin-walled longitudinal ripple extrudes to be finished.
Embodiment,
In the application of making domestic briquet stove chimney heat exchanger, shown in accompanying drawing 3,4, longitudinal corrugated pipe 17 is arranged among the heat exchanger shell 19 as chimney, the flue gas of coal stove 21 enters from longitudinal corrugated pipe 17 lower ends, discharge from the upper end, air blast 18 blows into the cold junction of cold air from heat exchanger shell 19, and the hot-air after the heat exchange is sent into indoor from the hot-blast outlet 20 of heat exchanger.Under the situation that existing civil heating coal stove is not made any changes, just change chimney and get final product heating with the installation airduct.And easy to install, energy-saving effect is remarkable, the heat exchange effect is very good since be forced ventilation thereby, the heating effect is existing more than 3 times of civil heating equipment.And invest more than 90% than hot-water heating saving.
