Description
Technical field
The utility model relates to a kind of production equipment of ultrahigh molecular weight polyethylene tubing, the special-purpose hemmer of specifically a kind of ultrahigh molecular weight polyethylene tubing.
Background technology
Ultra-high molecular weight polyethylene is a molecular weight greater than 1,500,000 polyethylene, is heated to more than the fusing point, still is elastomeric state, and can not as other thermoplastic, flows.Just because of this, the connected mode between the ultrahigh molecular weight polyethylene tubing adopts " hot melt butt welding " welding manner commonly used of common polythene tubing unworkable at all, welds insecure.For solving this difficult problem, people have adopted " flange connection " mode: the mode of the tubing two ends being carried out " high temperature preheating, the moulding of die pressure flange ".Traditional flange mode is: putting steel flanges above on the molecular weight polyethylene tubing in advance; Adopt the manual work of acetylene-oxygen welding gun to the preheating of heating of ultrahigh molecular weight polyethylene tubing two ends; After treating that tube end face reaches molten condition, manual work is compressed into tube end face with flanging die, cooling back mold removal; Tubing two ends end face will form the little flange like the flanging die shape like this; This little flange fixedly steel flanges can not come off from tubing, utilize to surpass the self sealss characteristics of molecular weight polyethylene material, and two tubes just can utilize flange directly to connect between only.The shortcoming of this traditional flange mode is: owing to utilize artificial acetylene-oxygen heating, people's experience is different, and heating can be inhomogeneous; And the bad control of temperature if temperature is low excessively, can cause the flange surface to be uneven; Sealing is bad during connecting leg, and material from leakage is as surpassing the melt temperature of ultra-high molecular weight polyethylene; Raw material will be degraded, and causes quality of item to descend, and reduces service life; Owing to be artificial compacting tool set, speed is slow, and the tubing cooling is fast, so the also necessary heating-up temperature height of tubing heating a bit.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of the utility model is to provide, operation easily, homogeneous heating, the special-purpose hemmer of ultrahigh molecular weight polyethylene tubing of raising flange quality.
In order to reach above purpose, the technical scheme that the utility model adopted is: the special-purpose hemmer of this ultrahigh molecular weight polyethylene tubing comprises operating desk; It is characterized in that: on operating desk, be fixed with after-poppet and fore-stock, on fore-stock, be fixed with sleeve pipe, sleeve pipe is provided with set bolt; On after-poppet, be fixed with ram, ram is evenly laid three, and the front end of ram is fixed with staking punch; The middle part of staking punch is provided with installation tube, and the middle part of installation tube is a positioning chamber.
The utility model is also implemented through following measure: be provided with cartridge heater in the positioning chamber of described installation tube, be provided with outer electrothermal ring and interior electrothermal ring in the chamber of cartridge heater.
Be provided with flanging die in the positioning chamber of described installation tube, the front end face of flanging die is provided with cannelure.
The beneficial effect of the utility model is: simple in structure, easy to use, and operation easily, tube end face flange homogeneous heating has improved the flange quality.

The specific embodiment
Make the utility model with reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4.The special-purpose hemmer of this ultrahigh molecular weight polyethylene tubing comprises operating desk 1, it is characterized in that: on operating desk 2, be fixed with after-poppet 2 and fore-stock 3; On fore-stock 3, be fixed with sleeve pipe 8, sleeve pipe 8 is provided with set bolt 9, and insert in the sleeve pipe 8 termination of ultrahigh molecular weight polyethylene tubing; And an outstanding segment distance, fixing with set bolt 9, on after-poppet 2, be fixed with ram 4; Ram 4 is evenly laid three; The front end of ram 4 is fixed with staking punch 5, and the middle part of staking punch 5 is provided with installation tube 6, and the middle part of installation tube 6 is a positioning chamber 7.
Be provided with cartridge heater 10 in the positioning chamber 7 of described installation tube 6; Be provided with outer electrothermal ring 11 and interior electrothermal ring 12 in the chamber of cartridge heater 10; In the time of need heating the termination of ultrahigh molecular weight polyethylene tubing, be placed on cartridge heater 10 in the positioning chamber 7 of installation tube 6 earlier, primer fluid bears down on one 4; Staking punch 5 moves forward to the end of ultrahigh molecular weight polyethylene tubing; The termination that makes ultrahigh molecular weight polyethylene tubing outside between electrothermal ring 11 and the interior electrothermal ring 12, energising utilizes the heat radiation of outer electrothermal ring 11 and interior electrothermal ring 12 to heat, and makes its fusion; Described outer electrothermal ring 11 can adopt stainless steel Far-infrared Heating circle with interior electrothermal ring 12; So that the inside and outside wall of while heating of plastic tubing; Outer electrothermal ring 11 internal diameters are greater than 4 centimetres of tube outer diameter, and interior electrothermal ring 12 external diameters are less than 4 centimetres of pipe internal diameters, prevent to heat inhomogeneous.
Be provided with flanging die 13 in the positioning chamber 7 of described installation tube 6, the front end face of flanging die 13 is provided with cannelure 14, and the shape of cannelure 14 is identical with the shape of flange; After the fusion of the termination of ultrahigh molecular weight polyethylene tubing, make ram 4 retractions, unload cartridge heater 10; Flanging die 13 is installed in the positioning chamber 7 of installation tube 6, ram 4 is stretched out, staking punch 5 marches to the end of ultrahigh molecular weight polyethylene tubing forward with flanging die 13; The termination of the ultrahigh molecular weight polyethylene tubing of molten condition is got in the cannelure 14; Being extruded to shape gets final product, and after the cooling, tube end face forms the shape same with flanging die 13 naturally.
