Production die for opened profiles

Abstract

The invention discloses a production die for opened profiles and relates to the technical field of production of profiles. A cleaver divider is arranged at a lower die inlet end at the center of a graph formed by surrounding of an extrusion hole, and the cleaver divider protrudes out of a plane of the lower die inlet end and stretches into a guide hole of an upper die. The die can effectively propel metal to flow to a place needing to be filled, and can avoid forming of a dead zone caused by accumulation of metal, thus being favorable for profile forming. Since metal accumulation is avoided, stress of a cantilever part of the lower die is relieved to a certain extent, the service life of the die is greatly prolonged, and compared with common dies, the extrusion pressure is reduced to a certain extent, and therefore, the production die is especially suitable for producing opened profiles.

Description

technical field [0001] The invention relates to the technical field of profile production, in particular to a production method of an open profile. Background technique [0002] The open profile is a common profile in the industrial and construction industries, which is generally processed by forging and milling. At this stage, extrusion is generally used for production and preparation. Extrusion production has a series of advantages, such as high production efficiency, dense internal structure of materials, material saving, and good heat transfer effect. [0003] For open-type materials, the method of pre-drainage die is generally used in the extrusion production process. This method will form a large dead zone at the front end of the diversion die. In the actual production process, it is found that due to The formation of the dead zone can easily lead to deformation or even collapse of the cantilever part of the mold, thereby affecting the quality of the profile and the ...

[0003] For open-type materials, the method of pre-drainage die is generally used in the extrusion production process. This method will form a large dead zone at the front end of the diversion die. In the actual production process, it is found that due to The formation of the dead zone can easily lead to deformation or even collapse of the cantilever part of the mold, which will affect the quality of the profile and the life of the mold. In addition, the existence of the dead zone is not conducive to the flow of metal
