Abstract
The utility model relates to an expanding bar for expanding oval special-shaped condenser tubes, which comprises an expanding bar. The expanding bar is characterized in that cross section of the expanding bar is oval, a clearance is arranged between the outer wall of the expanding bar and the inner wall of an oval special-shaped condenser tube, a circle of expanding joint is disposed at the edge of the top of the expanding bar, and the largest cross section of the expanding joint is slightly larger than the cross section of the inner wall of the oval special-shaped condenser tube. The expanding bar is characterized in that the expanding joint consists of three circular-arc surfaces which are in smooth connection, the top-section circular-arc surface is in round-corner transition connection with a top end surface of the expanding bar, and the bottom-section circular-arc surface is in smooth connection with the body of the expanding bar. The expanding bar has the advantages of being capable of tightly and fixedly connecting oval special-shaped condenser tubes with thin and soft radiating fins easily.
Description
Technical field
The utility model relates to a kind of bloated rod, particularly a kind of bloated rod that the special-shaped condenser pipe of ellipse is carried out reaming.
Background technology
Current rapid development of economy causes the in short supply of the energy, and in life and industrial production, use a large amount of refrigeration, heating equipment, consumed a large amount of energy, in order to improve the efficient of heat exchange, cut down the consumption of energy, condenser with special-shaped condenser pipe has been arranged, utilize special-shaped condenser pipe to make condenser and can reduce windage, help heat radiation, but in when assembling since usually the radiating fin on the condenser because thinner, soft, the through hole of wearing condenser pipe generally will be a bit larger tham the diameter of condenser pipe, be convenient to the smooth assembling on production line, yet in order to make the medium institute heat content and extraneous exchange in the condenser pipe, condenser pipe must be closely with being connected of radiating fin, if adopt welding, just may cause the rosin joint of product, leak weldering, thereby influence the quality of condenser, the problem that the special-shaped condenser pipe that therefore needs to be resolved hurrily is connected with the radiating fin fitting tight.
Summary of the invention
The purpose of this utility model is to solve existing problem in being connected of special-shaped condenser pipe and radiating fin in the prior art, provide a kind of can be with special-shaped condenser pipe and the bloated rod that approaches, soft radiating fin closely is fixedly coupled.A kind of bloated rod that the special-shaped condenser pipe of ellipse is carried out reaming of the utility model design, comprise the rod that expands, it is characterized in that: the cross section of the rod that expands is for oval, between the outer wall of bloated rod and the inwall of oval special-shaped condenser pipe the space is arranged, avris at the excellent top of expanding has a circle expansion joint, and the maximum cross section at expansion joint place is a bit larger tham the cross section of inboard wall of oval special-shaped condenser pipe.It is characterized in that: expansion joint is made up of three arc surfaces, and three smooth connections of arc surface have a round-corner transition to be connected between the top end face of top section arc surface and the rod that expands, back segment arc surface and bloated excellent smooth connection of barred body.The utility model has the advantages that and easily the special-shaped condenser pipe of ellipse closely to be fixedlyed connected with thin, soft radiating fin.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise the rod 1 that expands among the figure, it is characterized in that: the cross section of the rod 1 that expands is for oval, between the outer wall of bloated rod 1 and the inwall of oval special-shaped condenser pipe the space is arranged, avris at bloated excellent 1 top has a circle expansion joint 2, and the maximum cross section at expansion joint 2 places is a bit larger tham the cross section of inboard wall of oval special-shaped condenser pipe.It is characterized in that: expansion joint 2 is made up of three arc surfaces 4, and three arc surface 4 smooth connections have a fillet 3 transition to be connected between the top end face of top section arc surface and the rod 1 that expands, back segment arc surface 4 and bloated excellent 1 smooth connection of barred body.
When oval special-shaped condenser pipe is inserted into radiating fin in a row on assembly line, this moment, oval special-shaped condenser pipe was shape in upright arrangement, the rod that will expand is installed on the press, press is depressed after aiming at oval special-shaped condenser pipe, bloated rod enters in the oval special-shaped condenser pipe, with promptly fastening with radiating fin behind the special-shaped condenser pipe distending one of ellipse.Can carry out the processing of subsequent step then.
Claims (2)
1. bloated rod that the special-shaped condenser pipe of ellipse is carried out reaming, comprise the rod that expands, it is characterized in that: the cross section of the rod that expands is for oval, between the outer wall of bloated rod and the inwall of oval special-shaped condenser pipe the space is arranged, avris at the excellent top of expanding has a circle expansion joint, and the maximum cross section at expansion joint place is a bit larger tham the cross section of inboard wall of oval special-shaped condenser pipe.
2. by the described a kind of bloated rod that the special-shaped condenser pipe of ellipse is carried out reaming of claim 1, it is characterized in that: expansion joint is made up of three arc surfaces, three smooth connections of arc surface, there is a round-corner transition to be connected between the top end face of top section arc surface and the rod that expands, back segment arc surface and bloated excellent smooth connection of barred body.
