Special fixture for aluminum profiles and use method

Abstract

The invention discloses a special fixture for aluminum profiles and a use method of the special fixture. The special fixture comprises a fixture body and a support member, wherein the support member is of a groove type structure, and the support member is located at the bottom of the fixture body. Bowl-shaped fixing members are arranged on both sides of one end of the fixture body, and a stop block is arranged at the top of the other end of the fixture body. The stop block, the fixture body and the bowl-shaped fixing members are all made of copper materials, and the outer surface of the stop block is coated with a titanium alloy thin plate (the joint of the stop block and the fixture body is not coated with the titanium alloy thin plate). One end in a groove of the support member is fixedto the fixture body through a bolt and nut assembly, and the other end in the groove of the support member is fixed to the fixture body and the stop block through a bolt and nut assembly. The specialfixture for the aluminum profiles and the use method of the special fixture have the following advantages that the components of the fixture are correspondingly made of copper materials, stainless steel materials and titanium alloy materials, so that one end of the stop block of the fixture is enabled to extend into a bath solution, excellent electrical conductivity is achieved, the aluminum profiles clamped by the fixture are further enabled to enter the bath solution, and the aluminum profiles can be electrophoresed as a whole without producing an uncolored material head; and good clamping performance is ensured through a mechanism composed of a plate-shaped pressing tooth, an elastic bending plate, a cam and a rotating shaft, and the clamping effect can be improved with the increase ofthe own gravity of the profiles.

Description

technical field [0001] This application relates to the manufacturing technology of aluminum profiles, and specifically refers to a special fixture for aluminum profiles. Background technique [0002] In the production process of aluminum profiles, surface treatment processes such as anodic oxidation, electrolytic coloring, and electrophoretic coating are often used to make the surface more beautiful. There are strict requirements on the composition of the bath. Aluminum profiles need good electrical conductivity to become anodes or cathodes. However, if copper fixtures are inserted into the bath, they will easily become ions and dissolve into the bath, becoming a source of pollution for the bath. At the same time, the copper fixtures will dissolve. Therefore, the fixtures currently used in the industry cannot enter the bath, resulting in a section of aluminum profile above the liquid level of the bath, which cannot be colored and electrophoresed, resulting in waste of alumin...
