Shielding-type aluminum squeezing die with small opening and large pressure-bearing face

Abstract

The invention discloses a shielding-type aluminum squeezing die with a small opening and a large pressure-bearing face. The shielding-type aluminum squeezing die comprises a flow guiding die and a pattern cushion die, a flow distribution bridge is distributed on a material supply face of the flow guiding face and comprises a center flow distributing bridge body and a peripheral flow distributing bridge body, and a flow distributing hole is formed in the peripheral flow distributing bridge body. A weld-joint chamber is formed in the material feeding face of the pattern cushion die, an outlet relief layer is arranged on the material discharging face, and a work belt is arranged between the weld-joint chamber and the outlet relief layer. The length of the work belt is 4-10 mm. the weld-jointchamber is a two-time weld-joint chamber and comprises a first weld-joint chamber body and a second weld-joint chamber body. Compared with the prior art, The shielding-type aluminum squeezing die withthe small opening and the large pressure-bearing face has the advantages of being simple in structure, good in machining effect and the like.

Description

technical field [0001] The invention relates to the field of aluminum alloy extrusion die design, in particular to an aluminum extrusion die with a small opening and a large pressure-bearing surface shielding type. Background technique [0002] In recent years, with the rapid development of the aluminum alloy extrusion industry in China, it has become a trend for aluminum formwork to replace wood or steel pipes. However, in the aluminum alloy formwork section, not only the inner corner of the wall column (such as figure 1 As shown), the mold design is the most difficult, and it needs to be supplied with 6061 aluminum alloy and T6 state. It also requires aging treatment such as water quenching during extrusion production. The deformation of the profile is large and the processing is difficult, especially the uneven wall thickness. It is more difficult to control the deformation of the inner corner of the wall column with a small opening and a large pressure-bearing surface. ...

In the prior art, the design of the tear splitter mold is usually used to overcome the above difficulties. However, the structural mold of this design is difficult to maintain and the pass rate of the machine is low. Later, the tear process needs to be used, and the tear process is labor-intensive and time-consuming. And the profile after tearing the opening needs to be reshaped due to the large change in the opening size
