Abstract

The invention provides a D-shaped pipe molding device. The D-shaped pipe molding device comprises a fixed part and a movable part, wherein the fixed part comprises a fixed frame and a fixed piece; the fixed piece is fixed in the fixed frame and the side wall of the fixed piece is provided with a semicircular containing groove; a circular pipe can be contained in the semicircular containing groove; the movable part comprises a movable frame and a movable piece; the movable piece is fixed in the movable frame; the movable part is arranged in the fixed frame of the fixed part and can move relative to the fixed frame; the semicircular containing groove is formed in one side close to the movable piece of the fixed piece; and when the movable part gets close to the fixed piece of the fixed part, the movable piece can extrude the circular pipe on the fixed piece so that the circular pipe in the semicircular containing groove is extruded into a D-shaped pipe. With the adoption of the technical scheme, the D-shaped pipe molding can be realized rapidly and simply; and the D-shaped pipe is applied to a refrigerator so that the energy is saved and the consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of forming, in particular to a D-shaped tube forming device. Background technique [0002] The evaporator is the heat conductor of the freezer and refrigerator. The existing evaporators are all made of circular tubes, which are in line contact with the freezer and refrigerator liners, and have the disadvantages of slow cooling speed and small cooling depth, which is not conducive to energy saving and consumption reduction. There is a need for improvement. [0003] In the prior art, some D-shaped tubes are used, but the forming equipment of D-shaped tubes has complicated structure and high cost. [0004] Therefore, how to quickly and simply form the D-shaped tube has become a technical problem to be solved urgently. Contents of the invention [0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0006] To this end, an object of the ...
