Embodiment Construction

[0013] exist Figure 1-Figure 2 Among them, the front widening aluminum profile extrusion die is composed of a circular extrusion cylinder, a widening die, and a forming die. The widening die is placed in front of the forming die, and the middle part (2) of the cavity is larger than the left and right ends of the cavity (1, 3) narrowed by 25%-40%. The expansion angles (5) formed by the left and right end taper surfaces (4) of the die cavity and the axis of the front wide aluminum profile extrusion die are both 18-25°. The pressure relief angles (6) formed by the upper and lower tapered surfaces (7) and the axis of the die cavity of the front wide aluminum profile extrusion die are both 10-20°. In the extrusion process of this structure, when the end of the ingot flows into the center of the front wide expansion die, it does not flow out of the forming die immediately, but flows to both ends according to the principle of least resistance, balancing the pressure of the center a...

Abstract

The invention relates to a front-mounted broadened aluminum profile extruding die. The front-mounted broadened aluminum profile extruding die comprises a round extruding cylinder, a broadening die and a forming die, wherein the broadening die is arranged between the forming die and the round extruding cylinder, and the middle part of a die cavity of the broadening die is narrower than the left and right end parts of the die cavity by 25-40%; an extending angle formed by an upper conical surface of the die cavity and the axis is 18-25 degrees; a pressure relief angle formed by a lower conical surface of the die cavity and the axis is 10-20 degrees. According to the front-mounted broadened aluminum profile extruding die, a flat extruding cylinder is saved, the broadening effect of an ingot blank is good during the extruding, and the quality of a profile is improved; by utilizing the structure, the extrusion force can be reduced, the service life of the die can be prolonged, and the production cost can be lowered.

Description

technical field [0001] The invention relates to an aluminum profile extrusion die, in particular to a front wide aluminum profile extrusion die. Background technique [0002] Due to the increasingly wide application of aluminum profiles, the development of extrusion technology and extrusion dies has been effectively promoted. In recent years, wide-stretched aluminum row profiles have been widely used in conductive and fin radiators. And most of them have higher requirements on the surface and size of the profiles. At present, there are not many large-scale extrusion machines in our country, and the extrusion cost is high, so people often use small-tonnage extrusion machines to extrude super-rod profiles. However, since the deflector of the mold mostly adopts the direct push type feeding, the extrusion force is small, the aluminum deformation time is short, and the flow of external aluminum is small, resulting in insufficient aluminum supply at the outer edge of the mold, a...
