Compared with the method for mechanically expanding tubes, the hydraulic tube expanding device has the advantages that the expanding depth is large, the inner wall of a tube cannot be subjected to cold hardening or mechanical damage, the insufficient expansion and excessive expansion are avoided, the operation is convenient, the labor intensity is low, and safety and reliability are achieved.
Description
Technical field
The utility model relates to technical field of processing equipment, particularly a kind of hydraulic tube expansion device.
Background technology
At present, in the industry such as chemical industry, electric power, all kinds of heat exchanger tubes and tube sheet is connected, normally realize by traditional mechanical expanding method, because mechanical expanding labour intensity is large, inspection workload is large, and after roller rolling press, inner surface of tube can produce the phenomenon of flow harden and mechanical damage, the quality of product is greatly affected, thus the potential safety hazard of bringing.
Traditional pipe expanding equipment, except having the shortcoming such as labour intensity height and inefficiency, damage pipe, is also difficult to that tube plate thickness is exceeded to 100 millimeters of above heat exchangers and carries out through thickness expanded joints.And modern chemical industry device all moves under high parameter, the tube plate thickness of heat exchanger is more and more thicker, it is not rarely seen that tube plate thickness exceedes the heat exchanger of 200 millimeters, cannot carry out through thickness expanded joint to this thick tubular sheet heat exchanger by traditional mechanical expanding technology, make the part gap between heat exchanger tube and tube sheet be difficult to eliminate, the hidden danger of leaving gap corrosion.
Wish to make a kind of pipe-expanding device, by this device being installed, being reached the effect that makes expand tube convenience, efficiently, accurately controls expand tube pressure.
Utility model content
In order to solve the problems referred to above that exist in current pipe expanding mechanical equipment, now provide a kind of hydraulic tube expansion device.Concrete technical scheme is as follows:
A kind of hydraulic tube expansion device, comprise the pressure sensor on tube expander and tube expander, wherein, also include hydraulic system, described hydraulic system comprises hydraulic control one-way valve, two position and four-way reversing valve 1DT, two position and four-way reversing valve 2DT, Pressure gauge, check valve, hydraulic pump, filter screen, fuel tank, overflow valve.
Preferably, wherein hydraulic control one-way valve is connected with tube expander, two position and four-way reversing valve 1DT one end are connected with hydraulic control one-way valve, the other end is in parallel with two position and four-way reversing valve 2DT series winding whiles and tube expander, one check valve and two position and four-way reversing valve 2DT series winding, between check valve and two position and four-way reversing valve 2DT, be provided with Pressure gauge, be used for showing pressure, to be hydraulic pump contact simultaneously in parallelly with overflow valve again with filter screen and fuel tank the other end of check valve successively, and overflow valve is used for setting up system pressure and expand tube pressure.
Compared with prior art, a kind of hydraulic tube expansion device that technique scheme provides has the following advantages: by hydraulic system has been installed, make the workpiece quality of expand tube moulding obviously be better than the workpiece quality in common mechanical expand tube, and work efficiency improves obviously, alleviate greatly labour intensity, improve working environment, reduced fabrication cycle.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the hydraulic tube expansion device structural representation providing in the utility model embodiment.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, a kind of hydraulic tube expansion device, comprise the pressure sensor 2 on tube expander 1 and tube expander, wherein, also include hydraulic system, described hydraulic system comprises hydraulic control one-way valve 3, two position and four-way reversing valve 1DT4, two position and four-way reversing valve 2DT5, Pressure gauge 6, check valve 7, hydraulic pump 8, filter screen 9, fuel tank 10 and overflow valve 11.
A kind of hydraulic tube expansion device as shown in Figure 1, wherein hydraulic control one-way valve 3 is connected with tube expander 1, two position and four-way reversing valve 1DT4 one end and hydraulic control one-way valve 3 are contacted, the other end is in parallel with two position and four-way reversing valve 2DT5 series winding whiles and tube expander 1, one check valve 7 and two position and four-way reversing valve 2DT5 series winding, between check valve 7 and two position and four-way reversing valve 2DT5, be provided with Pressure gauge 6, be used for showing pressure, to be hydraulic pump 8 contact simultaneously in parallelly with overflow valve again with filter screen 9 and fuel tank 10 other end of check valve successively, and overflow valve is used for setting up system pressure and expand tube pressure.
Fig. 1 is the schematic diagram of ultrahigh-pressure hydraulic expand tube, and its course of action is: opening power hydraulic pump 8 is worked, and regulation relief valve 11 makes the reading of Pressure gauge 6 equal 1/15 of expand tube pressure.First the swollen head of tube expander 1 is inserted and treated in swollen pipe tube sheet, then magnetic valve 1DT4 connects tube expander 1 ante-chamber and boosts, piston is return simultaneously, magnetic valve 1DT4 closes, hydraulic control one-way valve 3 is also closed thereupon, then magnetic valve 2DT5 connects, tube expander piston-advance, thereby realize supercharging, the actual pressure of tube expander ante-chamber can show by pressure sensor 2 on digital display meter, pressurize rear electromagnetic valve 2DT5 in 3 second closes, tube expander ante-chamber, back cavity off-load simultaneously, and then swollen head being extracted is next root pipe of expansible.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
