Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment; specifically, the utility model relates to a thin-wall hollow cutter quenching tool. Background Art

[0002] Thin-walled hollow cutters are important parts of cutting tools. They need to be quenched during processing. When the thin-walled hollow cutters are heated above the critical temperature, their crystal structure becomes unstable, and then they form a martensitic structure under the action of rapid cooling. This structure has a higher hardness. After quenching, the thin-walled hollow cutters have higher strength, that is, their tensile and compression resistance is enhanced. The surface of the thin-walled hollow cutters after quenching is harder, so they have higher wear resistance, which enables the thin-walled hollow cutters to better resist friction and wear and extend their service life.

[0003] However, at present, there are certain problems in fixing the thin-walled hollow cutters during quenching. Some operators directly tie the thin-walled hollow cutters with wire, etc., and the thin-walled hollow cutters may expand and deform during the quenching process, resulting in a high frequency of unqualified thin-walled hollow cutters.

[0024] Figure 1 The figure is a schematic diagram of the structure of the thin-walled hollow cutter quenching tool of the utility model. The figure shows the bottom plate 1, the support plate 2 and the top plate 3 of the thin-walled hollow cutter quenching tool.

[0025] like Figure 1-4As shown, the quenching tooling includes: a bottom plate assembly, a plurality of support plate assemblies and a top plate assembly. The bottom plate assembly includes a bottom plate 1, bolts 4 and isolation nuts 5. First through holes 6 are provided at the four corners of the bottom plate 1. The bolts 4 pass through the first through holes 6 from bottom to top and are threadedly connected to the isolation nuts 5. Several support plate assemblies are arranged in sequence along the height direction on the bottom plate 1. The support plate assembly includes a support plate 2 and an isolation column 7 with a stud on the top. Second through holes 8 are provided at the four corners of the support plate 2. A threaded hole is provided at the bottom of the isolation column 7. The bolts 4 pass through the second through holes 8 from bottom to top and are threadedly connected to the threaded hole at the bottom of the isolation column 7. The studs of the isolation columns 7 of the lower support plate assembly pass through the second through holes 8 located above them and are threadedly connected to the threaded holes at the bottom of the isolation columns 7. The top plate assembly includes a top plate 3 and a locking nut 9. Third through holes 10 are provided at the four corners of the top plate 3. The studs of the isolation columns 7 pass through the third through holes 10 from bottom to top and are threadedly connected to the locking nut 9. Several openings 11 are provided on the top plate 3 and the support plate 2.

[0026] When in use, the thin-walled hollow cutter is inserted into the openings 11 of the top plate 3 and the support plate 2 from top to bottom. During quenching, the openings 11 of the top plate 3 and the support plate 2 can effectively prevent the thin-walled hollow cutter from expanding and deforming. Specifically, in this embodiment, two groups of support plate assemblies are provided, that is, there are two support plates 2. When corresponding to thin-walled hollow cutters of different lengths, the support plate assemblies can be increased or decreased as needed.

[0027] Furthermore, a first through hole 6 is opened at the center of the bottom plate 1, a second through hole 8 is opened at the center of the support plate 2, and a third through hole 10 is opened at the center of the top plate 3. The same connecting parts as those at the four corners are added at the center positions of the bottom plate 1, the support plate 2 and the top plate 3 to improve the overall stability.

[0028] Furthermore, the stud of the isolation column 7 passes through the third through hole 10 at the center of the top plate 3 from bottom to top, and is threadedly connected with the eye nut 12. The setting of the eye nut 12 facilitates the coordination of the whole with the external hook, making the whole easy to take.
