- the guide path 2a of the transfer body 23 carrying the heat exchanger or the heat exchanger guide path 2a for installation of the transfer device is a heat exchanger from one side of the base portion 2 to the other side It may be provided within the distance between the first guide bar 10 and the second ball screw 20 so as to be able to pass through.
- the second ball screw 20 is positioned near the front of the second guide bar 11 (the first guide bar 10 and the second guide bar 11 1 Between the first guide bar 10 and the second ball screw 20 (not shown). In this case, the transfer of the heat exchanger within the distance between the first guide bar 10 and the second ball screw 20 is also possible.
- the second ball screw 20 is rotatably held at the upper end thereof by the pair of holding portions 21 provided on the opposing inner wall surfaces of the columns 3 and the lower end is It is rotatably held at the left and right position on the rear side of the base unit 2 and is disposed in parallel with the first guide bar 10, but in this case, the second guide bar 11 and the second ball screw 20 It is possible to avoid the side-by-side arrangement in the front and rear direction of the diameter expansion device, and the advantage is that the width dimension of the diameter expansion device in the front and rear direction can be compacted as much as necessary. is there.
- the base unit 2 is provided with a fixing device 24 for positioning and fixing the transfer body 23 to the base unit 2 at a position where the diameter expansion of the heat exchanger is possible. 24 may be provided to the transfer body 23.
- the fixing device 24 may be configured to position and fix the heat exchanger directed from one side to the other side of the base portion 2 via the transfer body 23 at the position where the diameter can be increased. Even in the case where the heat exchanger transport route is straightened and the heat exchangers are sequentially carried into the diameter expansion device so that the heat exchanger can pass through the heat exchanger from one side of the side of the base portion 2 to the other side.
- the manufacturing line of the automated heat exchanger can be Has the advantage of being able to build
- the fixing device 24 provided on at least one of the base unit 2 or the transfer device can expand the diameter of the heat exchanger from one side of the base unit 2 to the other side via the transfer device.
- the heat exchanger Even if the heat exchanger is brought into the diameter expansion device one after another in a straight line, the heat exchanger can be reliably stopped at the position where the diameter can be expanded regardless of the operator's years of experience, etc. As well as being able to expand the diameter, it has the advantage of being able to construct an automated heat exchanger production line.
- first support 12 and the second support 13 may be integrally provided on the operation plate 6, the end plate 9 and the cover 19, and the support of the housing may be attached. It may be any of the configurations.
- bracket or slider is used for the first support 12 and the second support 13, it goes without saying that such a specific structure is not limited at all.
- first guide bar 10 and the third guide bar 14 are used for the first guide bar 10 and the third guide bar 14, it is needless to say that the present invention is not necessarily limited to the cylindrical shape.
- the pipe expansion apparatus is a so-called bowl-shaped pipe expansion apparatus, but the present invention is not necessarily limited to the bowl-shaped apparatus, and a horizontal pipe expansion apparatus according to the present invention is not limited to this. It goes without saying that it belongs to the range of Nor.
- the diameter expansion device for a heat exchanger using pipe is characterized in that, in the base portion, either the guide path of the transfer body carrying the heat exchanger or the heat exchanger guide path for installation of the transfer device is the base.
- a stand bar provided in the vicinity of the first guide bar and the second guide bar 11 or in the vicinity of the column 3 to be able to pass through the heat exchanger from one side of the pedestal side to the other side.
- the configuration is provided within the distance from the ball screw 20 of FIG.
- the side of the diameter-expanding device is located between the end plate positioned on both sides (lateral direction) of the diameter-expanding device Provide a space passage for carrying in the heat exchanger from one side (in the left-right direction) and carrying out the heat exchanger from the other side (the other side) within the distance between the first guide bar and the ball screw.
- the transfer path of the heat exchanger is straightened, that is, the heat exchanger is carried from one side (lateral direction) of the pipe expansion apparatus,
- a diameter expansion apparatus capable of constructing a suitable production line capable of enhancing the transfer efficiency and improving the productivity of heat exchangers by adopting a method of carrying out the heat exchanger from the side (so-called center-through method) It is.
