Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0030] Please refer to Figures 1-8 , the present application provides a short stress rolling mill, including a rolling steel component 2 and a deburring component 3;

[0031] The rolling steel member 2 includes a base 21 and mounting plates 22 provided on both sides thereof. A fixed rolling roll 23 and a movable rolling roll 24 are respectively provided between the two mounting plates 22. A support plate 25 is provided on the outer wall of one of the mounting plates 22, and a motor 26 with an output end connected to the fixed rolling roll 23 is mounted on the outside of the support plate 25;

[0032] The deburring member 3 includes a rotating shaft 31 rotatably provided on the support plate 25. A belt transmission member 32 is provided between the rotating shaft 31 and the output shaft of the motor 26. A bevel gear A33 is provided at one end of the rotating shaft 31. A bevel gear B34 meshing with the bevel gear A33 is slidably connected to the base 21. The bevel gear B34 is hollow and a grinding member 35 is provided therein.

[0033] In this embodiment, when the motor 26 is started, the fixed rolling roll 23 rotates self - rotatably. At the same time, with the assistance of the belt transmission member 32, the bevel gear A33 at the end of the rotating shaft 31 can also be made to rotate self - rotatably. Under the meshing transmission of the bevel gear A33 and the bevel gear B34, the grinding member 35 is also made to rotate. Such a design enables the workpiece to enter the grinding member 35 for more comprehensive grinding after passing between the fixed rolling roll 23 and the movable rolling roll 24. The rolling and grinding of the workpiece share one motor 26, reducing the use and maintenance costs of the rolling mill.

[0034] The belt transmission member 32 includes two belt pulleys A321 and belt pulleys B322 respectively fixed on the rotating shaft 31 and the output shaft of the motor 26. A belt 323 is tensioned between the belt pulley A321 and the belt pulley B322. Specifically, through the cooperation of the belt pulley A321, the belt pulley B322 and the belt 323, it is convenient to make the rotating shaft 31 and the fixed rolling roll 23 rotate synchronously, and also make the bevel gear A33 and the bevel gear B34 mesh and transmit power. In this way, the rolling and grinding of the workpiece can both operate under the drive of the motor 26.

[0035] The grinding member 35 includes sleeves 351 connected to the inner wall of the bevel gear B34 at equal intervals. A sleeve rod 352 is sleeved on the sleeve 351. A spring 353 is fixed between the inner end of the sleeve rod 352 and the inner end of the sleeve 351. The outer end of the sleeve rod 352 is fixedly connected to a grinding plate 354 with both ends bent outward. Specifically, as Figure 6 shown, by using the elastic cooperation of the sleeve 351 and the sleeve rod 352, it is convenient to make the grinding plate 354 movable to adapt to the grinding of steel bar workpieces of various different sizes.

[0036] Installation openings 221 are provided on the installation plate 22. Sliding seats A27, which are rotatably connected to both sides of the fixed roller 23, are fixed at the bottoms of the two installation openings 221. Sliding seats B28, which are rotatably connected to both sides of the movable roller 24, are slidably connected to the upper parts of the two installation openings 221. A screw rod 29 is rotatably connected to the sliding seat B28, and a top cover, which is threadedly connected to the screw rod 29, is fixed on the tops of the two installation plates 22. Specifically, bearings that are respectively rotationally matched with the fixed roller 23 and the movable roller 24 are embedded in both the sliding seat A27 and the sliding seat B28, enabling both the fixed roller 23 and the movable roller 24 to rotate. By turning the screw rod 29, the cooperation between the screw rod 29 and the screw holes on the top cover facilitates the displacement and fixation of the sliding seats B28 at both ends of the movable roller 24, thus facilitating the rolling of reinforcing bar workpieces of various different sizes.

[0037] A slider 36 is fixedly connected to the base 21, and a slide rail 341, which is adapted to the slider 36, is provided on the bevel gear B34. Specifically, as Figure 5 and Figure 7 shown, by using the design of the slider 36 and the slide rail 341, the bevel gear B34 on the base 21 can be rotated by itself under the drive of the bevel gear A33.

[0038] The present application further provides a dust suction mechanism, including the above-mentioned short stress rolling mill and a collection box 4 provided at the bottom of the base 21. Through openings 211, which are located on the outer sides below the grinding member 35, are provided in pairs on the base 21. Specifically, the cooperation between the collection box 4 and the through openings 211 facilitates the recovery of the metal chips that fall after grinding.

[0039] An exhaust fan 5, which is communicated with the inner cavity of the collection box 4, is fixed on the bottom side wall of the collection box 4. A draw opening 41 is provided on the side wall of the collection box 4, and a filter member 6 is slidably drawn on the draw opening 41;

[0040] The filter member 6 includes a filter net 61 that slides from the draw opening 41 into the collection box 4. A baffle 62 is fixedly provided on the outer wall of the filter net 61, and the baffle 62 is detachably fixed to the outer wall of the collection box 4.

[0041] The air extraction end of the exhaust fan 5 is located below the filter net 61. Specifically, starting the exhaust fan 5 can cause the metal chips after grinding to enter the collection box 4 under the action of its suction force and fall onto the filter net 61, and removing the baffle 62 and pulling out the filter net 61 facilitates the regular collection and cleaning of the metal chips in the collection box 4.

[0042] It should also be noted that a cushion block, which has the same height as the collection box 4, is further provided on the other side of the bottom of the base 21, thus increasing the stability of the present application when placed and used.

[0043] When the present application is used:

[0044] Start the motor 26, the fixed rolling roller 23 rotates on its own, and at the same time, with the assistance of the belt transmission member 32, the bevel gear A33 at the end of the rotating shaft 31 can also be made to rotate on its own. Under the meshing transmission of the bevel gear A33 and the bevel gear B34, the grinding member 35 is also made to rotate. Such a design enables the workpiece to enter the grinding member 35 for more comprehensive grinding after passing between the fixed rolling roller 23 and the movable rolling roller 24. The rolling and grinding of the workpiece share one motor 26, reducing the use and maintenance costs of the rolling mill. During the grinding process, starting the exhaust fan 5 can cause the metal chips after grinding to enter the collection box 4 under the action of its suction force and fall onto the filter screen 61. Removing the baffle 62 and pulling out the filter screen 61 facilitate the regular collection and cleaning of the metal chips in the collection box 4. In this way, the cleaning effect of the workpiece burrs is better and the rolling quality is higher.

[0045] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claims involved.
