[0002] A roll is a tool that causes plastic deformation of (rolled materials) metal and is an important consumable part that determines the efficiency of a rolling mill and the quality of rolled materials. A roll is an important part on a rolling mill in a rolling mill factory. It uses the pressure generated when a pair or a group of rolls roll to roll steel. It mainly bears the static and dynamic loads during rolling, wear, and the influence of temperature changes. Surfacing, as an economical and rapid process method for material surface modification, is more and more widely used in the manufacturing and repair of parts in various industrial departments; in order to most effectively play the role of the surfacing layer, it is hoped that the surfacing method adopted has less dilution of the base material, a higher deposition rate, and excellent surfacing layer properties, that is, a high-quality, high-efficiency, and low-dilution rate surfacing technology.
[0003] The existing roll surfacing machine tools on the market have the following several deficiencies: 1. When surfacing, the surfacing position cannot be effectively fixed, and the welding rod is easy to fall off. After the existing surfacing is completed, the roll is also required to enter a heating furnace for heat preservation and slow cooling to avoid cracking or falling off of the surfacing layer. This is neither efficient nor cost-effective; 2. The structure is complex, the body is heavy, and the operation process of the operator is relatively complex.
[0004] In view of the above several technical problems, it is particularly necessary to develop a high-efficiency roll surfacing machine tool. Content of the Utility Model
[0005] The purpose of the utility model is to provide a high-efficiency roll surfacing machine tool to solve the problems put forward in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical scheme: a high-efficiency roll surfacing machine tool, including a bed body. One side of the top of the bed body is fixedly installed with a longitudinal telescopic rod. The top of the longitudinal telescopic rod is fixedly installed with a transverse telescopic rod through a connecting seat. One end of the transverse telescopic rod is fixedly installed with a rectangular plate. The front of the rectangular plate is rotatably connected with an angle adjusting plate. The middle of the front of the angle adjusting plate is fixedly installed with a welding rod tube. The top of the front of the angle adjusting plate is fixedly installed with a welding rod box. The bottom end of the welding rod tube is connected with a head cover.
[0007] As a preferred technical scheme of the utility model, a screw rod is inserted through the front of the angle adjusting plate, and a nut is threadedly connected to the screw rod.
[0008] As a preferred technical scheme of the utility model, a welding rod heater is fixedly installed at the bottom end of the welding rod tube.

A through hole having the same diameter as the electrode tube is provided at the bottom end of the electrode holder. The electrode holder is communicated with the electrode tube through the through hole, and the diameter of the electrode tube is the same as the diameter of the electrode.
[0010] As a preferred technical solution of the present utility model, a bracket is fixedly installed on one side of the top end of the electrode holder, and two sets of guide wheels are correspondingly arranged on the bracket.
[0011] As a preferred technical solution of the present utility model, a column is fixedly installed on the other side of the top end of the bed body.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for a high-efficiency roll surfacing machine tool:
[0023] Embodiment 1:
[0024] According to Figure 1 , Figure 2 and Figure 3 shown, a high-efficiency roll surfacing machine tool includes a bed body 1. One side of the top of the bed body 1 is fixedly installed with a longitudinal telescopic rod 2. The top of the longitudinal telescopic rod 2 is fixedly installed with a transverse telescopic rod 4 through a connecting seat 3. The longitudinal telescopic rod 2 and the transverse telescopic rod 4 are convenient for adjusting the longitudinal and transverse telescopic adjustments of the welding structure. One end of the transverse telescopic rod 4 is fixedly installed with a rectangular plate 5. The front of the rectangular plate 5 is rotatably connected with an angle adjustment plate 6. A screw rod is inserted through the front of the angle adjustment plate 6, and a nut is threadedly connected to the screw rod. The provided threaded connection of the nut and the screw rod facilitates the position fixing of the angle adjustment plate 6 when the angle adjustment plate 6 is adjusted in angle. The middle of the front of the angle adjustment plate 6 is fixedly installed with an electrode tube 7. The top of the front of the angle adjustment plate 6 is fixedly installed with an electrode box 11. The bottom end of the electrode tube 7 is connected with a hood 9. One side of the top of the electrode box 11 is fixedly installed with a bracket 12. Two groups of guide wheels 13 are correspondingly arranged on the bracket 12. The guide wheels 13 facilitate the guiding of the flexible electrode and are convenient for subsequent welding.
[0025] The bottom end of the electrode tube 7 is fixedly installed with an electrode heater 8. The bottom end of the electrode heater 8 is communicated with the hood 9 through an electrode guide tube 20. One side of the bottom end of the electrode heater 8 is fixedly connected with the hood 9 through a connecting frame 19.
[0026] The width of the electrode box 11 is the same as the diameter of the electrode, avoiding excessive hard electrodes placed inside the electrode box 11, which may block the through-hole for discharging the electrodes in the electrode box 11. A through-hole with the same diameter as the electrode tube 7 is provided at the bottom end of the electrode box 11. The electrode box 11 is communicated with the electrode tube 7 through the through-hole. The diameter of the electrode tube 7 is the same as the diameter of the electrode, avoiding excessive electrodes discharged from the inside of the electrode box 11 at one time, which may cause blockage of the electrode tube 7.
[0027] During specific use, for the high-efficiency roll surfacing machine tool of the present utility model, adjust the telescopic stroke of the longitudinal telescopic rod 2 and the transverse telescopic rod 4 to adjust the position of the overall welding structure. After the position adjustment is completed, adjust the welding angle. At this time, through the rotational connection between the rectangular plate 5 and the angle adjustment plate 6, adjust the welding angle. After the angle adjustment, rotate the nut so that the nut presses the rectangular plate 5 and the angle adjustment plate 6 tightly, thereby fixing the position of the angle adjustment plate 6. When welding with hard electrodes, place the hard electrodes in the electrode box 11 at one time. At this time, the electrodes flow into the electrode tube 7 through the through-hole of the electrode box 11. Drive the electrode heater 8 to melt the electrodes. The molten electrodes flow from the electrode guiding tube 20 into the welding head cover 9 for welding. When welding with soft electrodes, pass the electrode through the guiding wheel 13, and one end of the electrode enters the electrode tube 7 through the through-hole at the bottom end of the electrode box 11, and repeat the above operation for welding.
[0028] Embodiment 2:
[0029] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, on the other side of the top end of the bed body 1, a column 14 is fixedly installed. At the top end of the column 14, a sand and gravel hopper 15 is fixedly installed. A rubber ring 17 is movably arranged in the middle of the sand and gravel hopper 15. A screen 16 is arranged inside the rubber ring 17. A striking plate 18 is movably placed on the top end of the screen 16. When the recycled sand and gravel are reused, there will be welding blocks in the recycled sand and gravel. The striking plate 18 strikes the sand and gravel hopper 15, and the screen 16 screens the welding blocks to avoid the existence of welding blocks in the recycled sand and gravel, which may affect subsequent use. The bottom end of the sand and gravel hopper 15 is communicated with the head cover 9 through a bent telescopic pipe 10.
[0030] During specific use, for the high-efficiency roll surfacing machine of the present utility model, during welding, at this time, the sand and gravel inside the sand and gravel hopper 15 flow into the inside of the electrode head cover 9 through the bent telescopic pipe 10, which can effectively solve the problem that the electrode does not fall or slip during surfacing on the roll. At the same time, it can also prevent the electrode welding blocks from being fixed everywhere on the workbench surface during welding. After use, the sand and gravel are recycled, and the recycled sand and gravel are poured into the sand and gravel hopper 15. There will be welding blocks in the recycled sand and gravel. The striking plate 18 strikes the sand and gravel hopper 15, and the sieve mesh 16 screens the welding blocks to avoid the existence of welding blocks in the recycled sand and gravel from affecting subsequent use.
