Description
Technical field
The utility model relates to the auxiliary mould of heat exchanger processing, is specially heat exchanger guiding device for pipe penetration.
Background technology
Heat exchanger be a kind of modal in chemical industry equipment be also a kind of equipment often used, but the most of the time will be used in the assembling of heat-exchanging tube bundle in the fabrication process, mainly because the pore on tube sheet and deflection plate exists deviation in process, the tube bank shelf taken before making poling produces twisted, this makes the pore on tube sheet and each deflection plate pore decentraction, add natural bow and the distortion of itself of heat exchanger tube leading portion, what make heat exchanger tube penetrates more difficult carrying out, and this is just difficult to penetrate after just causing always penetrating half when wearing heat exchanger tube; Owing to lacking special auxiliary mould, strike with hammer often in reality, simultaneously at tube bank side also handy hand and little crowbar guiding pipe, even if be also difficult to allow heat exchanger tube pass each layer deflection plate and tube sheet like this.
Summary of the invention
The utility model solves the problem lacking poling auxiliary mould in heat exchanger processing process, provides a kind of heat exchanger guiding device for pipe penetration.
The utility model adopts following technical scheme to realize: heat exchanger guiding device for pipe penetration, comprise leading section and be provided with screw thread, rear end is fixed with the central shaft of afterbody top board, on central shaft, cover has centering axle sleeve, the endoporus of centering axle sleeve is shoulder hole, central shaft leading section is screwed with locking nut, on central shaft, cover has the spring between the cascaded surface of the shoulder hole being compressed in locking nut and centering axle sleeve, the nose threads of centering axle sleeve is screwed with its anterior guideway for taper, be inserted with screw thread in guideway and twist guided push button in central shaft front end, central shaft rear end is provided with the afterbody addendum cone be placed on by its taper endoporus on the afterbody top board of central shaft and its rear end.During use, first guided push button is pressed, the afterbody top board of central shaft and its rear end is driven to move backward, thus it is swollen to remove the support of afterbody top board to afterbody addendum cone, afterbody addendum cone is made to be inserted tube end smoothly, then guided push button is unclamped, the elastic force of spring makes central shaft reset, afterbody top board the coordinating by the taper endoporus with afterbody addendum cone of its rear end, by the rear portion of afterbody addendum cone support distending, heat exchanging inside pipe wall produces radial pressure, when having pause or impact in poling process, frictional force between afterbody addendum cone and heat exchanger tube inwall can with guiding device for pipe penetration balance of shaking force forward, thus prevent guiding device for pipe penetration landing.The large I of spring force is adjusted by locking nut.The effect of centering axle sleeve makes the center of guiding device for pipe penetration consistent with heat exchanger tube center.Heat exchanger tube automatically can be introduced the pore of each deflection plate and tube sheet by anterior guideway in poling process.
Heat exchanger guiding device for pipe penetration reasonable in design described in the utility model, novelty, uniqueness, save human and material resources, improve operating efficiency, effective guarantee heat exchanger poling quality, and then improve workmanship and the working (machining) efficiency of whole heat exchanger, be a kind of aid of simple and practical processing heat exchanger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-afterbody top board, 2-afterbody addendum cone, 3-feels relieved axle sleeve, 4-central shaft, 5-spring, 6-guideway, 7-locking nut, 8-guided push button.
Detailed description of the invention
Heat exchanger guiding device for pipe penetration, comprise leading section and be provided with screw thread, rear end is fixed with the central shaft 4 of afterbody top board 1, on central shaft 4, cover has centering axle sleeve 3, the endoporus of centering axle sleeve 3 is shoulder hole, central shaft 4 leading section is screwed with locking nut 7, on central shaft, cover has the spring 5 between the cascaded surface of the shoulder hole being compressed in locking nut 7 and centering axle sleeve, the nose threads of centering axle sleeve 3 is screwed with its anterior guideway 6 for taper, be inserted with screw thread in guideway 6 and twist guided push button 8 in central shaft 4 front end, central shaft 4 rear end is provided with the afterbody addendum cone 2 be placed on by its taper endoporus on the afterbody top board 1 of central shaft and its rear end.During concrete enforcement, the rear portion external annular surface of afterbody addendum cone 2 is the face of cylinder, to increase contact surface between heat exchanger tube inwall and frictional force.The front portion of described afterbody addendum cone 2 is stretched in centering axle sleeve 3 (rear end of axle sleeve of namely feeling relieved has the hole coordinated with afterbody addendum cone); And for taper-face contact or coordinate (axle sleeve rear end of namely feel relieved be taper hole with the anterior hole coordinated of afterbody addendum cone) between the front portion of afterbody addendum cone 2 with centering axle sleeve 3, make the more reasonable structure of whole product.
