Abstract
A revolving tube expander is used for expanding a copper tube of a copper tube fin heat exchanger and comprises an expander body, an expanding rod and an expanding head, as well as an electric motor, a gear case, a sliding block, an expanding rod guide holder, a tail seat, a big air cylinder and a small air cylinder, wherein the electric motor is installed on the expander body and drives the expanding rod and the expanding head to revolve through the speed change of the gear case; and the big air cylinder is installed on the expander body and pushes the sliding block to do reciprocating motion, the expanding rod guide holder, the tail seat and the small air cylinder are installed on the sliding block, the expanding rod passes through the expanding rod guide holder, and the small air cylinder pushes the tail seat to control the length size of a heat exchange fin. By changing the linear motion of the original hydraulic expansion tube for a revolving motion, the tube expander leads to uniform wall thickness of tubular products, a revolving expansion tube is fast by more than 3 times, compared with the technology of the hydraulic expansion tube technique under the same conditions, and the manufacture cost of the heat exchanger is one third of that of the hydraulic expansion tube. In addition, the revolving tube expander is rather convenient for repair and maintenance.
Description
Technical field
The utility model relates to the electric tube expander that a kind of finned heat exchanger for gas heater, air conditioner heat exchanger and other field etc. carries out expand tube, especially relates to a kind of rotation electric tube expander.
Background technology
The copper tube and fin radiator need to increase the copper pipe diameter after fin is inserted in copper pipe, so that fin is enclosed within on the copper pipe firmly, thereby avoid loosening, makes both closely contact the minimizing heat transfer resistance simultaneously.What existing gas heater manufacturer and air conditioning system maker adopted all is the hydraulic expanding tube technology, its operation principle is: pass to oil cylinder after providing feed flow to press power by Hydraulic Station, then oil cylinder drives the motion that slide block that the expand tube frock is housed goes round and begins again under hydraulic power, thereby carries out expand tube work.
Hydraulic expanding tube is technical to be rectilinear motion, and the problem of existence is;
Can there be " tolerance " when one, tubing is produced, " position degree deviation " can occur on the hydraulic expanding tube operation.When position degree deviation makes hydraulic expanding tube, be easy to cause heat exchanger hole and not contraposition of expander roll, heat exchanger can occur bending and deformation and scrap on the expand tube operation, and general scrappage is about 1%～3%.If heat exchanger length lengthening, scrappage also will raise.
Two, hydraulic test needs often maintenance because of sealing part abrasion, hydraulic oil also will be often exchange device more, the cost of use height.
Three, heat is changed the sheet hydraulic expanding tube and can't be guaranteed product length, and length dimension is difficult to control; Heat is changed sheet and is also arranged evenly, makes fume emission freely not cause flue gas to exceed standard.
Four, heat exchanger does not descend because of expand tube does not tightly cause water heater complete machine thermic load, thereby causes product bad.
Five, production efficiency is low, and hydraulic press could be worked when specified pressure, and speed is very slow.
The utility model content
For this reason, the purpose of this utility model provides a kind of rotation electric tube expander, and its expander roll and the head that expands only rotate in pipe, and expand tube speed is fast, and compact conformation, and the expand tube cost is low.
For achieving the above object, the utility model provides technical scheme as described below:
A kind of rotation electric tube expander is used for the copper pipe of copper tube and fin heat exchanger is carried out expand tube, comprises fuselage, expander roll and bloated head, also comprises motor, gear-box, slide block, expander roll guide holder, tailstock and big cylinder, little cylinder; Described motor mounting drives expander roll and expands the head rotation by the gear-box speed change in fuselage; Described big cylinder is installed on fuselage, promotes described slide block and reciprocatingly moves, and expander roll guide holder, tailstock and little cylinder are installed on the slide block, and described expander roll passes described expander roll guide holder, and described stingy cylinder promotes described tailstock control heat exchange fin length size.
Workpiece is installed on the slide block and moves back and forth, the expander roll and the only rotation of head of expanding, and the expander roll guide holder that the expander roll and the head that expands pass on the slide block enters rotation expand tube in the pipe, and big cylinder promotes slide block gos deep in the pipe head that expands, and stingy cylinder promotes tailstock, the length of control heat exchange fin.
According to a preferred embodiment of the present utility model, also comprise big cylinder block and little cylinder block, described big cylinder block is installed on fuselage with bolt, and described big cylinder is installed on big cylinder block; Described little cylinder block is installed on fuselage with bolt, and described little cylinder is installed on little cylinder block.
According to another preferred embodiment of the present utility model, also comprise pneumatic floor push, step described pneumatic floor push and start described big cylinder and little cylinder.
According to another preferred embodiment of the present utility model, described fuselage is made by 50 * 50mm angle steel and the thick iron plate of 20mm.
According to another preferred embodiment of the present utility model, described bloated head forms with 40Cr structural alloy steel welding production for the YT14 carbide alloy.
According to another one preferred embodiment of the present utility model, the output shaft of described gear-box has the M10 internal thread, and expander roll one end has external screw thread and is attached thereto, and the other end has the M8 internal thread, and has the externally threaded bloated head of M8 and is connected.
Rotation electric tube expander of the present utility model becomes the rectilinear motion of original hydraulic expanding tube and rotatablely moves, make tube wall thickness even, and make heat exchanger heat change sheet and tubing under the effect of rotation in conjunction with very compact, heat exchanger product thermic load height, heat exchange fin at interval evenly, so the product fume emission is unimpeded, the heat exchange efficiency height.Compare with the hydraulic expanding tube technology, the rotation expand tube is fast more than 3 times down for equal conditions, and the manufacturing cost of heat exchanger is 1/3 of a hydraulic expanding tube.In addition, the maintenance of rotation electric tube expander is also very convenient.
Description of drawings
Fig. 1 is the schematic diagram according to the rotation electric tube expander of a specific embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in more detail.
Shown in Fig. 1 is schematic diagram according to the rotation electric tube expander of a specific embodiment of the present utility model, the slide block assembly that it comprises fuselage 12, is installed in the expand tube assembly on the fuselage 12 and can reciprocatingly moves.
The expand tube assembly comprises by bolting and is installed in motor 1 on the fuselage 12, gear-box 3, big cylinder block 10 and big cylinder 11.The main shaft of motor 1 is by fifth wheel 2 driven gear casees 3, and gear-box 3 drives expander roll 6 and expands 5 rotation.A 5 employing YT14 carbide alloy that expand form with 40Cr structural alloy steel welding production.The output shaft of gear-box 3 has the M10 internal thread, and expander roll 6 one ends have external screw thread and are attached thereto, and expander roll 6 other ends have the M8 internal thread, and has externally threaded expand of M8 and 5 is connected.
