Problems solved by technology

[0003] However, in the anodizing devices currently used in the industry, there is no reliable hanger for special use, but simple hooks or conductive wires are used.
These traditional hangers have greatly affected the efficiency of hanging workpieces, and the workpieces picked up by traditional hangers are relatively single, which cannot adapt to the pace of diversification of production products today; furthermore, traditional hangers cannot guarantee the oxidation quality of products , especially when faced with diversified products, it is more difficult to control

Embodiment 1

[0040] In order to improve the strength and operability of the hanger of the present invention, the structure and connection of the fixed hook 6 and the threaded post 7 are optimized, as image 3 , Figure 5 As shown, the fixed hook 6 is provided with two hinged ears 61, the stud head 71 is hinged between the two hinged ears 61, and the cross section of the stud head 71 is set as an oblate or square structure;

Embodiment 2

[0042] Such as Figure 4 , Image 6 As shown, the fixed hook 6 is provided with a T-shaped groove 62, and the stud head 71 is set as a T-shaped structure to cooperate with the T-shaped groove 62 of the fixed hook 6. This structure can avoid the process of inserting the hinge shaft, and the operation is simpler , in order to ensure the stability when the threaded post 7 is connected with the fixed hook 6, such as Figure 7 As shown, the T-shaped slot 62 is provided with a positioning slot 63 for positioning the stud head 71 . Of course, the connection relationship between the fixed hook 6 and the threaded column 7 can also be set as threaded connection, hook connection, etc., which will not be repeated here, and all these equivalent forms also fall within the scope of protection defined by the present application.

[0043] In order to facilitate the loading and unloading of the hanger and meet the needs of humanization, the present invention has a handle 2 on the main rod, wh...

Abstract

The invention discloses a special rack for surface anodic oxidation, and belongs to the technical field of surface treatment of workpieces. The rack comprises a main rod with an adjustable length, wherein a hanging piece is arranged on one end of the main rod, a fixed pothook is arranged on the other end of the main rod, and the fixed pothook is detachably connected with a threaded column which is connected with a threaded hole in the workpiece to be oxidized. A rubber cushion is arranged on the threaded stud for sealing the threaded hole, connected with the threaded column, on the workpiece to be oxidized; and a handle and a detection interface are arranged on the main rod. The rack provided by the invention can be connected with the different workpieces with different sizes of threaded holes by adjusting the diameter of the threaded rod on the threaded column, so that the current diversified flexible connection requirement of the product is met, and the rack is convenient to use, recycle and replace; the detection interface is arranged on the main rod of the rack, so that specific detection on oxidization parameters such as current and temperature of the product in an oxidization device is facilitated, the oxidization process is effectively detected, and the oxidization effect is convenient to control and improve.

Description

technical field [0001] The invention relates to the technical field of workpiece surface treatment, in particular to a special hanger for surface anodic oxidation. Background technique [0002] AC7A aluminum alloy is a new type of aluminum-magnesium casting alloy with light texture and excellent machining performance. It is currently the most respected aluminum for molds in the world and is widely used in the field of tire mold manufacturing. However, in actual production, the tire mold performs frequent precise opening and closing movements during the tire vulcanization process. Because the hardness of the AC7A aluminum alloy is relatively low (65HB) and the surface wear resistance is poor, the contact surface of the aluminum alloy tire mold block is in the Severe wear and tear during the opening and closing process limits the service life of the mold. In order to prolong the service life of tire molds, it is the demand of some high-end molds to improve the surface hardnes...
