Laminated continuous extrusion metal tube mosquito coil production line and production method

Abstract

The invention relates to a laminated continuous extrusion metal tube mosquito coil production line. The laminated continuous extrusion metal tube mosquito coil production line sequentially comprises an aluminum rod cutting device, an aluminum rod cleaning device, an aluminum tube extruder, an aluminum tube cooling treatment device, aluminum tube pulling devices and a formed aluminum tube coiling device; a formed aluminum tube bending mechanism is arranged between the aluminum tube pulling devices and is mounted at the discharging ends of the aluminum rod pulling devices; the formed aluminum tube coiling device is arranged under the formed aluminum tube bending mechanism; the formed aluminum tube bending mechanism and the formed aluminum tube coiling device can move relatively in the height direction; the laminated continuous extrusion metal tube mosquito coil production line further comprises a lifting device; and the intervals between the upper surfaces of laminated spirally-coiled aluminum coils on the formed aluminum tube bending mechanism and the formed aluminum tube coiling device are make to be equal through the lifting device. The invention further discloses a production method for producing the laminated continuous extrusion metal tube mosquito coils based on the production line. The production line has the advantages of being compact in structure, convenient to use, high in production efficiency, capable of achieving automatic operation easily and the like.

Description

technical field [0001] The invention belongs to the technical field of continuous extrusion metal pipe production, in particular to a laminated continuous extrusion metal pipe mosquito coil production line and a production method. Background technique [0002] At present, in the automobile and air-conditioning industries, a large number of metal pipes are used to produce automobile water tanks, evaporators, air-conditioning condensers, and heat exchangers. At present, the metal pipe generally adopts a disc-shaped structure, that is, a long metal tube is wound on a cylindrical receiving mandrel. The wound disc-shaped structure is cylindrical in appearance, and its center is an inner hole of the same diameter; The lead-out joint of the disc-shaped metal pipe of this structure is arranged in the inner hole, and when the user uses it, it can be drawn and intercepted according to actual needs. The disc-shaped metal tube solves the inconvenience caused by the traditional single s...

Problems solved by technology

Once the entire disc-shaped metal tube is stuck or knotted, it will cause a lot of waste of metal tubes

In addition, when the drawn metal tube is moving, if it vibrates or shifts due to other reasons, the drawn metal tube will scratch the undrawn metal tube in the inner ring, thus affecting the quality of the product. quality

After the collection of the cylindrical material receiving mandrel is completed, when it is necessary to take out the cylindrical material receiving mandrel, since the two ends have the same diameter, there is a large friction force on the entire material receiving mandrel when pulling out, which is inconvenient Take out the receiving mandrel, if a large force is applied when taking it out, the inner metal tube attached to the receiving mandrel will be scratched

[0003] In addition, the minimum standard of the existing disc structure is generally 70mm in outer diameter, 30mm in height, and 65kg in weight; the largest is 140mm, 30mm in height, and 190kg in weight; from the above dimensions, due to the constraints of the receiving tray , the height of the coil cannot be changed, so the existing coil needs to be larger and can only have more coils, which undoubtedly increases the radial volume of the product and brings inconvenient
