Embodiment Construction
[0033] An embodiment of the flaring molding die of the connecting pipe of the present invention, the flaring forming mold cooperates with the flaring machine to flaring the connecting pipe, such as figure 1 , figure 2 and image 3 As shown, it includes a fixed mold 100 and a movable mold 200 arranged oppositely;
[0034] Such as Figure 4 and Figure 5 As shown, a fixed mold flaring restriction wall 110 is provided on the opposite side of the fixed mold and the movable mold; Figure 6 and Figure 7 As shown, a movable mold flaring restriction wall 210 is provided on the opposite side of the movable mold to the fixed mold;
[0035] The movable mold 200 can move relative to the fixed mold 100 within a predetermined range; the movable mold flaring limiting wall 210 and the fixed mold flaring limiting wall 110 can be combined to form a wall for limiting the connecting pipe. The flared flare restricts the wall. When the distance between the movable mold 200 and the fixed mo...

Abstract
The invention discloses a flaring forming mold and method of a connecting pipe. The flaring forming mold is matched with a flaring machine to perform flaring on the connecting pipe; the flaring forming mold comprises a fixed mold and a movable mold which are oppositely arranged; one side of the fixed mold, which is opposite to the movable mold, is provided with the fixed mold flaring limiting wall; one side of the movable mold, which is opposite to the fixed mold, is provided with the movable mold flaring limiting wall; the movable mold can move opposite to the fixed mold in a preset range; the movable mold flaring limiting wall can combine with the fixed mold flaring limiting wall to form into the flaring limiting wall which is used for limiting a flaring of the connecting pipe. The flaring forming method is a usage method of the flaring forming mold. The flaring forming mold and method of the connecting pipe enables the size of the flaring to be accurate and stable.
Description
technical field [0001] The invention relates to the field of flaring pipe fittings, in particular to a flaring forming mold and a flaring forming method for connecting pipes. Background technique [0002] The split type air conditioner is composed of an indoor unit and an outdoor unit, the heat exchanger of the outdoor unit is a condenser, and the heat exchanger of the indoor unit is an evaporator. The indoor unit and the outdoor unit are connected through a connecting pipe, and the refrigerant circulates in the connecting pipe connecting the outdoor unit and the indoor unit, and realizes a heat exchange cycle through the evaporator, compressor and condenser to achieve the effect of refrigeration. Today's air-conditioning connecting pipes are divided into two types: copper and copper-aluminum composite materials. [0003] The connection between metal pipe fittings often adopts port flaring process to realize the connection between metal pipe fittings; as a kind of metal pip...
