Description

Technical Field

[0001] The utility model relates to the technical field related to hangers, in particular to an elastic hanger for saw blade electrophoresis. Background Art

[0002] Carbide circular saw blades are important cutting tools for woodworking, aluminum, and ironworking. They are mainly composed of alloy teeth and a saw blade base. The saw blade base is generally made of high-carbon steel or alloy tool steel. Therefore, when production is completed, the entire saw blade must be sealed with an electrophoretic coating of anti-rust paint to prevent oxidation and rust from long-term exposure to the air. Cathodic electrophoretic coating is to immerse the conductive saw blade in a tank filled with water-diluted, relatively low-concentration electrophoretic coating as a cathode, and set a corresponding anode in the tank. Direct current is passed between the two poles to precipitate a uniform, water-insoluble coating on the saw blade. Existing saw blades use hooks as hangers (the hanger is energized to make the saw blade charged when the saw blade is electroplated), as shown in the attached manual. Figure 1 As shown, the hook A1 has no tension, and the conductivity between the saw blade A2 and the hook depends on the weight of the saw blade itself. A heavy saw blade has good contact and conductivity, while a light saw blade has poor conductivity. This will cause the light saw blade to have a higher electrophoresis defect rate. To improve the electrophoresis yield, it is necessary to process the coating on the hook at the contact position with the saw blade to improve the conductivity. Frequent processing of the coating on the hook is time-consuming and affects production efficiency. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the present utility model is to provide an elastic hanger for saw blade electrophoresis to solve the above technical problems.

[0004] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0005] According to one aspect of the utility model, an elastic hanger for saw blade electrophoresis is designed, comprising: a hanging rod and an elastic fixing frame, a hook is provided on the upper part of the hanging rod, the elastic fixing frame is connected to the hanging rod, the elastic fixing frame comprises an upper elastic rod and a lower elastic rod, one end of the upper elastic rod is connected to one end of the lower elastic rod, an upper clamping groove is provided on the upper elastic rod, and a lower clamping groove is provided on the lower elastic rod, and the distance between the upper clamping groove and the lower clamping groove is greater than the diameter of the circular hole on the saw blade.

[0006] When the above technical solution is adopted, when the saw blade needs to be installed on the elastic fixing frame, the saw blade is moved close to one end of the elastic fixing frame, so that the end connected to the upper elastic rod and the lower elastic rod is inserted into the circular hole on the saw blade. As the saw blade moves, the saw blade contacts and rubs with the upper elastic rod and the lower elastic rod, and the saw blade drives the upper elastic rod and the lower elastic rod to elastically deform and approach each other. The friction between the saw blade and the upper elastic rod and the lower elastic rod can scrape off the electrophoretic coating on the upper elastic rod and the lower elastic rod, thereby enhancing the conductivity between the saw blade and the elastic fixing frame, and avoiding the problem of frequent paint stripping of the hanger. When the saw blade is matched with the upper card slot and the lower card slot, it can be installed with a limit, and the upper elastic rod and the lower elastic rod elastically abut against the saw blade, further improving the electrical performance, thereby improving the yield rate of the electrophoretic treatment of the saw blade, and thus improving the production efficiency of the saw blade.

[0007] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0008] In some embodiments, the upper elastic rod is connected to the lower elastic rod via a spring ring. The provision of the spring ring can enhance the elasticity of the upper elastic rod and the lower elastic rod, and improve the electrical conductivity between the upper elastic rod and the lower elastic rod and the saw blade.

[0009] In some embodiments, two lower elastic rods are provided, and the two lower elastic rods are correspondingly connected to two ends of the upper elastic rod.

[0010] In some embodiments, two lower elastic rods are provided, and both ends of the upper elastic rod are connected to the lower elastic rods via spring rings.

[0011] In some embodiments, the upper elastic rod, the lower elastic rod and the spring coil are integrally formed by bending stainless steel wire.

[0012] In some embodiments, the upper portion of the upper elastic rod is bent to form an arc-shaped portion.

[0013] In some embodiments, the arc-shaped portion is connected to the hanging rod via a locking member.

[0014] In some embodiments, the arc-shaped portion is welded to the hanging rod.

[0015] In some embodiments, there are more than one elastic fixing bracket. When there are more than two elastic fixing brackets, they are vertically distributed and respectively connected to the hanging rods. BRIEF DESCRIPTION OF THE DRAWINGS
