Bending device for thin-walled snake-shaped heat exchange tubes

Abstract

Provided is a bending device for thin-walled snake-shaped heat exchange tubes. A box body is of an upper-end-open structure defined by a bottom plate, three side plates and a box door hinged to one side plate, and a bending platform is fixed to the upper end opening of the box body; a driving motor is installed in the box body, the driving motor is connected with a bending mechanism through a transmission piece, the lower half part of the bending mechanism is arranged in the box body, the upper half part of the bending mechanism is installed on the bending platform, and a feeding port positioning mechanism arranged on the surface of the bending platform is located on the right side of the bending mechanism; a resetting mechanism connected with the lower end of the bending mechanism is arranged in the box body; and after the driving motor drives the bending mechanism to rotate by a certain angle, bending of a to-be-bent rod piece which penetrates through the feeding port positioning mechanism and is inserted into the bending mechanism is achieved. The bending device overcomes quality defects caused by the deformation of the bending positions of the thin-walled snake-shaped heat exchange tubes, filling is not needed, the bending efficiency is improved, the uniformity of bent finished products is good, the bending process is mechanically completed, the labor intensity of staff isgreatly reduced, and the use value is high.

Description

technical field [0001] The invention belongs to the technical field of heat exchange tubes, and in particular relates to a bending device for thin-wall serpentine heat exchange tubes. Background technique [0002] The heat exchange tube is one of the elements of the heat exchanger. It is placed in the cylinder and used for heat exchange between two media. It has high thermal conductivity and good isothermal performance. A device that transmits heat from one point to another with almost no heat loss, so it is called a heat transfer superconductor, and its thermal conductivity is thousands of times that of copper. In order to improve the heat dissipation efficiency of heat exchange tubes, people generally use serpentine heat exchange tubes. However, at present, when processing serpentine heat exchange tubes, two workers usually work together to cold-bend them. Wrinkle, before bending, fill the inside of the pipe fitting to be bent (that is, fill it with sand before bending), ...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a bending equipment for thin-walled serpentine heat exchange tubes. By setting the bending mechanism with the upper half installed on the bending platform in the box, and by the The drive motor drives the bending mechanism to rotate at a fixed angle to realize the bending of the rods to be bent that pass through the feed port adjustment mechanism on the bending platform and inserted into the bending mechanism, which solves the problem of thin-walled snake-shaped heat exchange tubes. The bending position has quality defects due to deformation. There is no need to fill the inside of the rod to be bent, which improves the bending efficiency. use value
