The expanded tube device is characterized in that the expanded head component comprises a plurality of expanded head pull rods, the upper ends of the expanded head pull rods are arranged on the expanded head pull rod seat, and each expanded head pull rod is sequentially provided with an expanded rod bush, an elastic expanded sleeve and a guide nut in a sleeved mode; the expanded rod bushes are fixed in through holes in the bottom of the expanded connection seat, and the upper portion of the expanded connection seat is connected to a cylinder body of a hydraulic cylinder through the fixing plate; the expanded head pull rod seat is connected to a hydraulic cylinder pull rod through the hydraulic cylinder connecting plate. The expanded tube device is simple in structure, convenient to operate, low in requirement for the size precision of product parts, high in production efficiency, capable of being connected with a single end in an expanding mode or with two ends in an expanding mode simultaneously, capable of being directly used for a sticking expand tube process and also capable of being used for a pre-expanding process before welding.
Description
Technical field
The utility model relates to mechanical field, relates in particular to shell-and-tube/pipe type heat exchanger field, and in shell-and-tube/pipe type heat exchanger manufacturing process, a plurality of tube-to-tube sheet connections are the expand tube device of expanded joint simultaneously specifically.
Technical background
Shell-and-tube/pipe type heat exchanger is a kind of important structural shape of field of heat exchangers; the connection of tube-to-tube sheet connection be during shell-and-tube/pipe type heat exchanger is manufactured topmost operation this one of; this operation adopts single tube and tube sheet to carry out expanded joint processing technology one by one usually; therefore to expend man-hour many for the expanded joint operation; handwork is than great; the craftsmanship requires and the manipulation strength height; operation processing efficient is low; entire product in the manufacturing cycle holding time long; product is made the time cost height; the batch process efficient that is unfavorable for product improves, and can't adapt to modern needs of scale production.
Summary of the invention
To be solved in the utility model is the problems referred to above that exist in the present technological method for processing, aims to provide a kind of working (machining) efficiency height, low cost of manufacture, simple to operate, expand tube device that manual work intensity is low.
The technical scheme that addresses the above problem employing is: a kind of expand tube device, comprise a draw-bar seat that expands, expanded joint seat, bloated an assembly, fixed head and hydraulic cylinder connecting plate, it is characterized in that a described assembly that expands comprises a plurality of pull bar that expand, the upper end of a described pull bar that expands is arranged on the described draw-bar seat that expands, suit expander roll lining, elastic expansion sleeve and spigot nut successively on each pull bar that expands; Described expander roll lining is fixed in the bottom through-hole of described expanded joint seat, and described expanded joint seat top is connected to the cylinder body of hydraulic cylinder by described fixed head; A described draw-bar seat that expands is connected to the hydraulic cylinder pull bar by the hydraulic cylinder connecting plate.
Expand tube device of the present utility model, carry out expand tube according to the following steps:
1. the expand tube device is linked to each other with the movable support of electric tube expander, this activity support provides power for the expand tube device;
2. mobile movable support enters in one group of pipe one group of pull bar that expands of expand tube device correspondingly;
3. open hydraulic mechanism, the hydraulic cylinder pull bar is twitched, and drives a pull bar that expands and moves, and then move by the spigot nut drive elastic expansion sleeve of a tie rod end that expands; The elastic expansion sleeve axial compression produces distortion in the space that pipe, expander roll lining, a pull bar that expands, spigot nut constitute, because axial length reduces, elastic expansion sleeve is radially swollen, and radially swells to expand with tube sheet and closes thereby promote institute's expand tube;
4. close and open hydraulic mechanism and rush down pressure, the hydraulic cylinder pull bar resets, and drives a pull bar that expands and resets, and takes off pipe and tube sheet assembly.
Expand tube device of the present utility model, expand tube is responsible for by an assembly that expands in the expand tube position of each tube-to-tube sheet connection, and all assemblies that expand are realized the expand tube operation by the unified control of expand tube device, and a quantity that expands and expand tube position all can be adjusted according to product needed.When tube-to-tube sheet connection assembling is finished and behind expand tube device location, the expand tube device once moves, and namely finishes the expand tube operation operation of expand tube that remains.Therefore, the utility model is simple in structure, and is easy to operate, low to the product parts dimension precision requirement simultaneously, the production efficiency height, but can single-ended expanded joint also two ends expanded joint simultaneously, can make directly to paste the expansion tube process that expands and use, also can make the pre-process application that expands before the weldering.
As further improvement of the utility model, described fixed head is connected to the cylinder body of hydraulic cylinder by an installing plate.Installing plate is thinner than fixed head, and the convenient installing hole of offering thereon makes more simple with being connected of cylinder body and convenient.
