Description

Technical Field

[0001] The utility model relates to the technical field of coating tooling, in particular to a hot riveting head magnetic coating tooling. Background Art

[0002] A hot rivet head is a device used for processing plastic melts, primarily for producing various plastic products. Depending on the processing requirements, there are different types of hot rivet heads, including flat hot rivet heads, circular hot rivet heads, and Fisher hot rivet heads.

[0003] Since these hot rivet heads often adhere to plastics, the most non-sticky type currently available is a PTFE coating. PTFE, short for polytetrafluoroethylene, is a plastic material with excellent non-stick properties, corrosion resistance, insulation, and high-temperature resistance. Coating the PTFE surface of the hot rivet head effectively prevents plastic from adhering to the die, ensuring long-term performance and processing quality.

[0004] However, PTFE coating has poor high temperature resistance. For the melt processing of some high melting point plastics, DLC coating is often used instead of PTFE coating. DLC coating has a higher application temperature, up to 350 degrees, and has good anti-sticking effect. It works excellently as an anti-stick coating on hot rivet heads.

[0005] Although the size of the hot rivet head is not large, if special tooling is not used for coating clamping, the clamping efficiency will be slow, the coating quality will be unstable, the coating appearance will be unstable, the coating thickness will be uneven, the clamping quantity will be small, and the coating cost will be high.

[0009] In order to facilitate driving the tooling to rotate and thus realize coating processing of each end face, the clamping hole is a square hole, the clamping hole is connected with the clamping rod, and the rotation of the clamping rod drives the entire tooling body to rotate.

[0010] In order to improve coating efficiency, preferably, the polyhedron hanger is a pentahedron; in order to ensure the stability of clamping, there are two hanging holes.

[0011] In order to facilitate the disassembly and assembly of various components, the magnetic hanging plate includes a magnetic plate, a clamping plate and a limit frame.

The clamping plate covers the surface of the magnetic plate and can slide along the limit frames on both sides and stop at the limit frame at the bottom.

[0012] In order to facilitate the disassembly and assembly of the hot rivet head, the magnetic plate is evenly provided with magnetic holes, and high-temperature magnets are embedded in the magnetic holes. The clamping plate is evenly provided with through holes that can clamp the hot rivet head and correspond to each magnetic hole one by one.

[0019] like Figure 1-4 The hot rivet head magnetic coating tool shown includes a tool body, which includes a polyhedron hanger 1 and a magnetic hanging plate. The polyhedron hanger 1 has clamping holes 3 at both ends. The polyhedron hanger 1 has multiple clamping end faces in the circumference, and each clamping end face has two hanging holes 2. The magnetic hanging plate is detachably connected to the hanging hole 2.

Each end face in the length direction of the tooling body 1 is respectively provided with two hanging holes 2. The magnetic hanging plate includes a magnetic plate 4, a clamping plate 5 and a limit frame 7. The back of the magnetic plate 4 is detachably connected to the hanging hole 2 by a snap. A number of magnetic holes 6 are evenly provided on the magnetic plate 4, and high-temperature magnets are embedded in the magnetic holes 6. Limiting frames 7 and limiting frames 10 are respectively welded on both sides and the bottom of the magnetic plate 4. A guide groove is formed between the limit frame 7 and the magnetic plate 4.
