[0030] As attached Figure 1 -Attached Figure 5 As shown, the utility model provides a square rod rounding device, comprising a rod material carrying mechanism 22 and a square rod rounding mechanism 23, wherein the rod material carrying mechanism 22 and the square rod rounding mechanism 23 are both arranged on a support 21, the rod material carrying mechanism 22 is used to carry the rod material, and the square rod rounding mechanism 23 is used to grind the square rod into a round rod;

[0031] The square rod rounding mechanism 23 comprises a rotation driving device 232 and two rounding wheels 231, the axes of the two rounding wheels 231 are parallel to each other, and the wheel body interval of the two rounding wheels 231 is smaller than the diameter of the rod to be rounded, and the rotation driving device 232 drives at least one of the rounding wheels 231 to rotate, preferably, the rotation driving device 232 drives the two rounding wheels 231 to rotate in opposite directions;

[0032] The bar material carrying mechanism 22 includes a carrying track 221, and the carrying track 221 is arranged between two grinding wheels 231, and the carrying surface of the carrying track 221 is arranged toward the interval between the two grinding wheels 231. The square bar is placed on the carrying surface of the carrying track 221, and the side surfaces of the square bar are in contact with the two grinding wheels 231. The grinding wheels 231 grind the side surfaces of the square bar during rotation, and during the grinding process, the square bar will rotate with the grinding wheels 231 to ensure the roundness of the square bar.

[0033] The square rod rounding device provided by the utility model is different from the conventional method of directly placing the square rod from the upper ends of the two rounding wheels 231 and then rounding the square rod by the gravity. The interval between the two rounding wheels 231 does not need to be adjusted, the rounding efficiency is higher and the quality is better. Furthermore, the installation method of the two rounding wheels 231 can adopt a fixed installation method, the structure is simple and reliable, and the maintenance frequency of the device can be reduced and the service life of the device can be increased.

[0034] In one embodiment, the bar stock carrying mechanism 22 further includes a position adjusting mechanism 222. The position adjusting mechanism 222 is used to adjust the distance between the carrying track 221 and the two rounding wheels 231. In this embodiment, the distance between the carrying track 221 and the two rounding wheels 231 can be adjusted by the position adjusting mechanism 222. On the one hand, it is convenient for loading and unloading the bar stock 10. Specifically, when loading the square bar, the carrying track 221 can be driven to move away from the interval between the two rounding wheels 231 first, and the bar stock 10 can be placed on the carrying surface of the carrying track 221 manually or by means of instruments. Then, the carrying track 221 is driven to move closer to the interval between the two rounding wheels 231 for rounding. When unloading the square bar, the carrying track 221 is driven to move away from the interval between the two rounding wheels 231 again, and the round bar is taken away from the carrying surface of the carrying track 221 manually or by means of instruments. On the other hand, by adjusting the distance between the carrying track 221 and the two rounding wheels 231, it can be used to adapt to square bars of different sizes for rounding work, and the diameter of the rounded bar can also be adjusted.

[0035] In one embodiment, both ends of the carrying track 221 extend beyond both ends of the two rounding wheels 231;

[0036] The position adjusting mechanism 222 includes a linear moving mechanism 2221 and two vertical connecting plates 2222 arranged at the output end of the linear moving mechanism 2221. The other ends of the vertical connecting plates 2222 are connected to the ends of the carrying track 221. That is, the two vertical connecting plates 2222 and the carrying track 221 form a "U" - shaped structure, which can ensure the synchronous movement of both ends of the carrying track 221 and improve the structural strength of the carrying track 221. In this embodiment, the carrying track 221 is indirectly arranged on the support 21 through the linear moving mechanism 2221;

[0037] The moving direction of the linear moving mechanism 2221 is perpendicular to the plane where the axes of the two rounding wheels 231 are located. Thus, the linear moving mechanism 2221 drives the carrying track 221 to always move perpendicularly towards the plane where the axes of the two rounding wheels 231 are located, so that the roundness of the bar stock in all directions is consistent.

[0038] Among them, the linear moving mechanism 2221 can be selected as manual or automatic according to actual needs, such as various linear driving methods like cylinders, hydraulic cylinders, linear modules, screw - nut pairs, etc. Preferably, a linear driving method with position locking is adopted, so that the carrying track 221 can be kept in the set position.

[0039] In one embodiment, mounting blocks 2213 are provided at both ends of the supporting rail 221, and the vertical connecting plate 2222 is fixedly connected to the mounting blocks 2213, that is, the supporting rail 221 is in an "I"-shaped structure, which can ensure that the range of the supporting rail 221 within the two grinding wheels 231 is small and will not contact the grinding wheels 231, while the position extending out from the two ends of the two grinding wheels 231 is large, thereby improving the connection strength with the vertical connecting plate 2222.

[0040] In one embodiment, the two ends of the bearing track 221 are respectively a square bar entry end 2211 and a round bar exit end 2212. In this embodiment, the bar material can be directly loaded and unloaded along the axial direction of the rounding wheel 231 through the bearing track 221, that is, the movement and transportation of the bar material is realized during the rounding process of the square bar, and the rounded bar material 10 can be conveniently directly transported to the next station in the axial direction of the bar material 10, making the transportation of the bar material simpler and more reliable, and more convenient for directly transporting or processing the bar material to the next process.

[0041] In one of the embodiments, it also includes a rod moving mechanism, which is used to push the rod from the square rod entry end 2211 into the support track 221, and push the rod out of the support track 221 from the round rod output end 2212. In this embodiment, one end of the square rod enters the support track 221 from the square rod entry end 2211, and the entered part immediately contacts the two grinding wheels 231 and performs a rounding operation. In the process of the rod moving mechanism continuously pushing the rod into the support track 221, the newly pushed part is rounded accordingly, and then the square rod is rounded from one end to the other end in sequence. On the one hand, it can reduce the burden of the square rod rounding mechanism 23, and on the other hand, each part of the square rod can be rounded through the wheel body in the entire length direction of the grinding wheel 231, which can improve the rounding effect of the rod. In an embodiment with a vertical connecting plate 2222, a square through hole 22221 is provided on the vertical connecting plate 2222, and a mounting block 2213 is fixed at the bottom of the through hole 22221 by fasteners, while other parts of the through hole 22221 are used as a square rod entry end 2211 and a round rod output end 2212.

[0042] In one embodiment, the square rod rounding device further includes a round rod output track 24 connected to the round rod output end 2212, so as to directly carry the rounded rod material 10 so as to transport the round rod to the next station for processing.

[0043] In one embodiment, the two circular grinding wheels 231 are respectively an alloy grinding wheel and a silicone wheel, which can ensure the processing effect.

[0044] In one embodiment, the distance between the wheel bodies of the two grinding wheels 231 is zero, that is, the two grinding wheels 231 are arranged tangentially. At this time, the two grinding wheels 231 rotate in opposite directions. In this embodiment, the two grinding wheels 231 can grind round rods of the smallest size, and there will be no situation in which the grinding cannot be continued when the size of the round rod is smaller than the distance between them.

[0045] In one of the embodiments, the square rod rounding device also includes a spraying mechanism 25 arranged above the wheel body interval of the two rounding wheels 231, which is used to spray water on the two rounding wheels 231. On the one hand, the rounding wheels 231 are cooled to ensure the temperature, and on the other hand, the debris of the rod material 10 can be prevented from floating in the support 21 to avoid dust.

[0046] The above is only an embodiment and does not limit the present invention in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the present invention without departing from the scope of the present invention by using the above disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
