[0002] Rebar is the common name for hot-rolled ribbed steel bars, which are widely used in the construction of civil engineering projects such as houses, bridges, and roads. It has longitudinal and transverse ribs on its surface, which can enhance the bond strength with concrete and improve the overall strength and stability of the building. During the construction process, it is often necessary to cut the rebar into specific lengths according to actual needs. This is because different parts of the building structure have different requirements for the length of the steel bars, and only through shearing can the precise requirements of the construction be met.

[0003] In the related art, a mechanical shearing device is usually used to shear the rebar, and a hydraulically driven shearing tool is used to cut the rebar through strong pressure. However, during the shearing process, the existing rebar shearing device is prone to uneven ends of the rebar and burrs due to tool wear, uneven distribution of shearing force, etc. When connecting the steel bars, the uneven ends will lead to loose connections and reduce the integrity and stability of the structure. In addition, the ends of the rebar with burrs are easy to scratch construction workers and pose a threat to their safety. Therefore, after shearing the rebar, the uneven ends need to be processed secondary, such as grinding, which not only increases construction costs, but also wastes time and resources.

[0026] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The threaded steel shearing equipment according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0028] The threaded steel shearing equipment provided in the embodiment of the present application can be used in the construction or production and processing of threaded steel for shearing threaded steel. It can automatically grind the end of the threaded steel after the shearing is completed to effectively ensure the flatness of the end of the threaded steel, provide more reliable protection for the safety of the construction project, and effectively reduce the safety hazards of construction personnel, thereby improving the safety and work efficiency of construction.

[0029] like Figure 1-Figure 5 As shown, the threaded steel shearing equipment of the embodiment of the present application may include a shearing table 1, a clamping mechanism 2, a cutting tool 3, a driving member 4 and a grinding assembly 5.

[0030] The clamping mechanism 2 and the driving member 4 are respectively arranged on the shearing table 1 , the cutting tool 3 is arranged on the driving member 4 , and a device cavity is opened in the cutting tool 3 .

[0031] The grinding assembly 5 may include a grinding disc 51 , a sleeve 52 , a rotating rod 53 , a driving mechanism 54 and a reciprocating mechanism 55 .

[0032] Among them, the sleeve 52 is rotatably arranged in the device cavity, the rotating rod 53 is axially slidably connected to the sleeve 52, a receiving groove connected to the device cavity is opened on the side of the cutting tool 3 close to the clamping mechanism 2, the grinding disc 51 is located in the receiving groove, and the grinding disc 51 is connected to the rotating rod 53, the driving mechanism 54 is arranged on the shearing table 1, and the driving mechanism 54 is respectively connected to the driving member 4 and the sleeve 52, and the reciprocating mechanism 55 is arranged on the driving mechanism 54, and the reciprocating mechanism 55 is respectively connected to the driving member 4 and the rotating rod 53.

[0033] Specifically, when shearing the threaded steel, the relevant personnel first clamp and fix the threaded steel through the clamping mechanism 2, and then start the driving member 4 to drive the cutting tool 3 to shear the excess threaded steel. After the shearing of the threaded steel is completed, the driving member 4 drives the cutting tool 3 to reset. In the process of the driving member 4 driving the cutting tool 3 to shear and reset, the driving member 4 also cooperates with the driving mechanism 54 to drive the rotating rod 53 and the grinding disc 51 to rotate, so that in the process of resetting the cutting tool 3, the reciprocating mechanism 55 drives the grinding disc 51 through the rotating rod 53 to extend out of the receiving groove and contact with the end of the threaded steel. The ends of the threaded steel bars are in contact with each other, so that the end of the threaded steel bar is automatically polished while the polishing disc 51 is rotating, effectively ensuring the flatness of the end of the threaded steel bar, and the end of the threaded steel bar after automatic polishing has no burrs, eliminating the safety hazard to the construction workers. The construction workers do not need to worry about being scratched when transporting and installing the threaded steel bars, and can work more safely. In addition, the technical solution integrates the two processes of shearing and polishing, realizes automated operation, and avoids secondary processing due to the uneven end of the threaded steel bar. Compared with the traditional method of shearing first and then polishing, it greatly saves time and labor costs.

[0034] In one embodiment of the present application, Figure 1-Figure 5 As shown, the clamping mechanism 2 may include a first hydraulic cylinder 201 , a movable block 202 and a fixed block 203 .

[0035] The first hydraulic cylinder 201 is fixedly arranged on the shearing platform 1 , the movable block 202 is fixedly arranged on the movable end of the first hydraulic cylinder 201 , the fixed block 203 is fixedly arranged on the shearing platform 1 , and the fixed block 203 is located on a side of the movable block 202 away from the first hydraulic cylinder 201 .

[0036] Specifically, when shearing the threaded steel bar, the relevant personnel first place the threaded steel bar to be sheared between the movable block 202 and the fixed block 203, and place the threaded steel bar to be sheared at the alignment position of the cutting tool 3, and then drive the movable block 202 to move toward the fixed block 203 through the first hydraulic cylinder 201 to clamp and fix the threaded steel bar.

[0037] In one embodiment of the present application, Figure 1-Figure 5 As shown, the driving member 4 can be set as a second hydraulic cylinder, and the cutting tool 3 is fixedly arranged on the movable end of the second hydraulic cylinder.

[0038] Specifically, the relevant personnel start the second hydraulic cylinder to drive the cutting tool 3 to shear the threaded steel outside the fixed block 203 and the movable block 202, and cut off the excess length of the threaded steel through the hydraulic pressure and the cutting force of the cutting tool 3.

[0039] In one embodiment of the present application, Figure 1-Figure 5 As shown, a plurality of slide grooves are formed on the inner wall of the sleeve 52 along its length direction, and a plurality of slide keys 531 adapted to the slide grooves are fixedly provided on the outer peripheral surface of the rotating rod 53 .

[0040] Specifically, through the cooperation between the plurality of slide grooves and the plurality of sliding keys 531 , the sleeve 52 can drive the rotating rod 53 to rotate while the rotating rod 53 can still slide back and forth on the sleeve 52 .

[0041] In one embodiment of the present application, Figure 1-Figure 5 As shown, the driving mechanism 54 may include a gear 541 and a spur rack 542 .

[0042] The end of the sleeve 52 away from the grinding disc 51 passes through the cutting tool 3 and is coaxially fixedly connected to the gear 541 . The spur rack 542 is fixedly arranged on the shearing table 1 , and the spur rack 542 is meshedly connected to the gear 541 .

[0043] Specifically, while the driving member 4 drives the cutting tool 3 to perform shearing and resetting operations, the cutting tool 3 also drives the gear 541 to move, so as to drive the sleeve 52 to rotate under the meshing action of the gear 541 and the spur rack 542, and then drives the rotating rod 53 and the grinding disk 51 to rotate through the sleeve 52, so that the end of the threaded steel bar can be ground by the grinding disk 51 in a rotating state.

[0044] It should be noted that the module of the spur rack 542 described in this embodiment should be smaller than the module of the gear 541, so that during the coordinated movement, the distance moved by the spur rack 542 is relatively small for each rotation of the gear 541, so that the rotation speed of the gear 541 is faster than the movement speed of the spur rack 542, thereby achieving a speed-increasing effect on the gear 541, so as to improve the grinding effect on the end of the threaded steel bar by increasing the rotation speed of the grinding disk 51.

[0045] In one embodiment of the present application, Figure 1-Figure 5 As shown, the reciprocating mechanism 55 may include a fixed box 557 , a connecting rod 551 , a rotating ring 552 , a rotating key 553 , a partition plate 554 , a first inclined plate 555 and a second inclined plate 556 .

[0046] Among them, the rotating ring 552 is rotatably mounted on the rotating rod 53, the connecting rod 551 is slidably set on the cutting tool 3, and one end of the connecting rod 551 is fixedly connected to the rotating ring 552 through a coupling, the fixed box 557 is fixedly set on the spur rack 542, the partition 554 is fixedly set in the fixed box 557, and the left and right sides of the partition 554 and the inner side wall of the fixed box 557 respectively form a first sliding area and a second sliding area, the rotating key 553 is rotatably set on the other end of the connecting rod 551, and the rotating key 553 is vertically set between the connecting rod 551, the rotating key 553 is slidably connected to the first sliding area and the second sliding area respectively, the first inclined plate 555 and the second inclined plate 556 are respectively fixedly set in the first sliding area and the second sliding area, and the first inclined plate 555 and the second inclined plate 556 are respectively located on the front and back sides of the partition 554.

[0047] It should be noted that the first sliding area described in this embodiment is located on the side of the partition 554 away from the cutting tool 3, and when the rotating key 553 is located in the first sliding area, the grinding disc 51 is always in the receiving groove to prevent the grinding disc 51 from affecting the shearing of the threaded steel by the cutting tool 3.

[0048] Specifically, during the process of the driving member 4 driving the cutting tool 3 to shear the threaded steel, the rotating key 553 slides in the first sliding area to place the grinding disc 51 in the receiving groove. When the cutting tool 3 moves to the end point, the rotating key 553 will move to the second sliding area under the action of the first inclined plate 555 to push the rotating rod 53 and the grinding disc 51 to move to the outside of the receiving groove, so that during the resetting process of the cutting tool 3, the grinding disc 51 can be brought into contact with the end of the threaded steel, so that the grinding effect on the end of the threaded steel can be achieved through the grinding disc 51 in a rotating state. After the cutting tool 3 is reset, the rotating key 553 will re-enter the first sliding area under the action of the second inclined plate 556 to reset the grinding disc 51. At this point, the shearing of the threaded steel and the grinding of the end can be completed simultaneously.

[0049] In summary, the rebar shearing equipment of the embodiment of the present application can automatically grind the end of the rebar after the shearing is completed, so as to effectively ensure the flatness of the end of the rebar, provide more reliable protection for the safety of the construction project, and effectively reduce the safety hazards of construction personnel and improve the safety and work efficiency of construction.
