[0002] The hydraulic prop includes a hydraulic prop body, and the hydraulic prop body includes an outer cylinder and a plunger inside the cylinder. The cylinder has an inner cavity, and the plunger is installed in the inner cavity. The plunger has a layer of coating, which is the original coating. During long-term use, the outer periphery of the plunger is worn, especially the original coating, that is, the thickness of the original coating is reduced, so that there is a large gap between the outer side of the plunger and the inner side of the cylinder, which causes the entire hydraulic prop to be scrapped and cannot be used normally.

[0003] The scrapped hydraulic support can be repaired to form a regenerated hydraulic support. The regeneration of the hydraulic support is an important part of cost saving.

[0004] In order to make the regenerated hydraulic support obtain the technical effect of long service life, a plurality of grooves are formed on the outside of the plunger of the hydraulic support; in the prior art, ordinary turning tools are used to form the plurality of grooves on the outside of the plunger of the hydraulic support, which requires multiple processing, has the disadvantage of low production efficiency, and cannot meet some processing requirements. Summary of the invention

[0005] The purpose of the utility model is to provide a turning tool for a regenerative hydraulic support with high production efficiency and convenient use in view of the above shortcomings.

[0006] The technical solution adopted by the hydraulic support of the utility model is: a turning tool for a regenerative hydraulic support, including a turning tool body, the turning tool body having an upper mounting handle and a lower processing plate, the processing plate being a planar plate-like structure, characterized in that: a plurality of processing heads are arranged at intervals below the processing plate, the lower ends of the processing heads are blades, the length directions of these blades are parallel to the surface direction of the processing plate, these blades are first blades, and the edges of the contact plates are between adjacent processing heads.

[0007] The multiple grooves formed on the plunger are to ensure that the plating formed on the outside of the plunger is more firmly connected to the plunger. This plating is a regenerated plating.

[0008] Furthermore, the plurality of first blades are gradually densely arranged from one end to the other end on the side below the processing plate. The better technical effect of processing the plunger is that the grooves on the plunger are gradually densely arranged from one end to the other end, and such a turning tool just meets the requirements of the grooves on the plunger.

[0009] Furthermore, a slit knife is also arranged at the edge of the contact plate, and the slit knife has blades, and the length direction of these blades is perpendicular to the surface direction of the processing plate, and these blades are second blades.

[0010] Furthermore, the first blade is 1-2 mm higher than the edge of the contact plate.

[0011] Furthermore, the length of the second blade is 1-2 mm.

[0012] The beneficial effect of the utility model is that the turning tool has the advantages of high production efficiency and convenient use when regenerating the plunger of the hydraulic prop. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 , 2 As shown in Figure 3, a turning tool for a regenerative hydraulic support includes a turning tool body, wherein the turning tool body has an upper mounting handle 1 and a lower processing plate 2, wherein the processing plate is a planar plate-like structure, characterized in that: a plurality of processing heads 3 are arranged at intervals below the processing plate, and the lower ends of the processing heads are cutting edges, the length directions of these cutting edges are parallel to the surface direction of the processing plate, these cutting edges are first cutting edges 31, and there are contact plate edges 4 between adjacent processing heads.

[0019] Using principle, the utility model is arranged as above, when in use, the mounting handle and the plunger are mounted on a lathe, the first blade processes the side of the plunger, and multiple grooves can be processed on the plunger of the hydraulic support at one time, the production efficiency is high, the use is convenient, and the purpose of the utility model can be achieved.

[0020] The purpose of forming multiple grooves on the plunger is to make the newly formed plating on the outside of the plunger more firmly connected to the plunger. This plating is a regenerated plating.

[0021] Furthermore, the plurality of first blades are gradually densely arranged from one end to the other end on the side below the processing plate. The better technical effect of processing the plunger is that the grooves on the plunger are gradually densely arranged from one end to the other end, and such a turning tool just meets the requirements of the grooves on the plunger.

[0022] Furthermore, a slit knife 5 is provided at the edge of the contact plate. The slit knife has blades, the length directions of which are perpendicular to the surface direction of the processing plate. These blades are second blades 51.

[0023] The utility model is arranged in this way, and can also realize the gap with multiple scratches formed on the plunger, that is, the gap formed by the second blade, so that the regenerated plating layer formed later and the plunger are more firmly connected.

[0024] Furthermore, the first blade is 1-2 mm higher than the edge of the contact plate.

[0025] The utility model is arranged in this way, that is, the first blade can make the processed groove depth reach 1-2 mm, which is more in line with the process requirements.

[0026] Furthermore, the length of the second blade is 1-2 mm.

[0027] The utility model is arranged in this way, that is, the second blade can form multiple scratches on the plunger column with a gap of 1-2 mm, which better meets the process requirements.
