Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for machining the upper die of a porthole die, and specifically discloses a machining tooling for the upper die of a porthole die. Background Art

[0002] A porthole die is a die for processing aluminum bars into aluminum profiles through extrusion. The porthole die is mainly divided into two parts: an upper die and a lower die. The upper and lower dies cooperate to jointly form the cross-sectional shape of the aluminum profile, and together they form the porthole die. The upper die spread is a specific area designed at the aluminum bar inlet position of the upper die of the porthole die, which extends downward and outward at a certain angle or multiple angles and becomes wider due to the requirements of the aluminum profile extrusion process. Among them, the spread angle is an important parameter in the design, which determines the flow direction and speed of the metal during extrusion.

[0003] In the machining of the spread position of the upper die of the porthole die in the prior art, first, a common milling machine is used to deflect the angle for measurement and machining, then a CNC electric discharge machine is used for forming and chamfering machining, and finally, a fitter is used for grinding and smoothing machining. The above machining process uses machine tools with low automation and manual machining. There are great differences in the sense of responsibility, technical level, and process understanding ability of the operators, resulting in low standardization, low replicability, and low machining efficiency. To solve the above problems, a five-axis machining center can also be used for direct machining, but the cost of the five-axis machining center is relatively high, and the number of units configured by general machining enterprises is limited. The other machining tasks of the five-axis machining center are also relatively heavy, resulting in limited improvement in machining efficiency.
