Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic shearing equipment, in particular to a steel bar cutting machine with a protective structure. Background Art

[0002] After the structural concrete pouring of some buildings is completed, due to the failure to completely wrap the steel bars during the concrete pouring process or the deviation in the positioning of the steel bars, some of the steel bar ends will be exposed on the outside. These exposed steel bars not only affect the aesthetics of the project, but may also cause obstacles to subsequent construction, hinder the removal of the formwork or affect the installation of other components. Therefore, it is necessary to use cutting equipment to cut off the excess steel bars;

[0003] When cutting off the excess steel bars on the building structure, a handheld hydraulic shear is generally used to directly cut off the excess steel bars from the end, such as the Chinese utility model patent disclosed by publication number CN212201417U: a micro-excavation hydraulic shear. The application adopts a single hydraulic cylinder to reduce the volume of the hydraulic shear and the weight of the hydraulic shear. The shear teeth and the shear rod are the same length, which can make the single hydraulic cylinder better push the hydraulic shear and increase the shearing force of the hydraulic shear. The synchronous teeth can synchronize the shear teeth to prevent the phenomenon of poor bite caused by the asynchronization of the shear teeth during shearing, thereby achieving stability during operation. However, when the end of the steel bar is cut off through this application, the hydraulic shear will apply a huge shearing force at the moment of cutting the steel bar. This force will quickly act on the steel bar, causing a strong reaction force when the steel bar breaks, so that the cut steel bar fragments fly out, and the flying steel bar fragments are easy to splash onto people, causing injuries.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a steel bar cutting machine with a protective structure, including a hydraulic shear body 1, a handle 2 is fixedly installed on the rear side of the hydraulic shear body 1, a switch 3 is movably installed in the handle 2, and the switch 3 is electrically connected to the main control board in the hydraulic shear body 1, a handle 4 is fixedly installed on the top of the hydraulic shear body 1, a knife seat 5 is fixedly installed on the front side of the hydraulic shear body 1, a shearing assembly 6 is movably installed on the front side of the knife seat 5, and a protective mechanism 7 is arranged on the outside of the knife seat 5, the protective mechanism 7 includes two arc-shaped mounting seats 8 and a fixed ring 9 and a movable cover 10, the fixed ring 9 and the movable cover 10 are movably connected to each other by a plurality of connecting screws 11, and the fixed ring 9 is also fixedly installed on one side of the shearing assembly 6 through the arc-shaped mounting seat 8.

[0022] like Figure 2-Figure 3As shown, the two sides of the two arc-shaped mounting seats 8 are respectively fixedly installed with fixing seats 12, and bolts are inserted and connected between the two fixing seats 12. The arc-shaped mounting seats 8 are fixedly installed on the outside of the knife seat 5 through the two fixing seats 12 and the bolts. Through the arrangement of the two arc-shaped mounting seats 8, the fixing ring 9 and the movable cover 10 can be installed on one side of the shearing assembly 6. A plurality of first fixing rods 13 are fixedly installed on one side of the fixing ring 9. The fixing ring 9 located between the two first fixing rods 13 is also provided with a screw groove 14. An end block 17 is fixedly installed at one end of the connecting screw 11, and the other end of the connecting screw 11 is threadedly connected in the corresponding screw groove 14. Two first connecting rods 15 are fixedly installed on the outside of the fixing ring 9. The first connecting rods 15 are L-shaped. The ends of the two first connecting rods 15 away from the fixing ring 9 are respectively fixedly installed with connecting seats 16. The connecting seats 16 are inserted and installed between the two fixing seats 12 and fixed by bolts.

[0023] like Figure 2-Figure 5 As shown, a plurality of second fixing rods 18 are fixedly installed on one side of the movable cover 10, and a second connecting rod 19 is fixedly connected between the two second fixing rods 18. Through the arrangement of the second fixing rod 18, when the end of the steel bar is cut, the end of the steel bar can automatically contact the recessed part on one side of the movable cover 10, so that the movable cover 10 drives the plurality of second fixing rods 18 to move smoothly. The two second fixing rods 18 are inserted and installed between the corresponding two first fixing rods 13, and the second connecting rod 19 is also inserted and installed on the corresponding connecting screw 11 by using the internal through hole.

[0024] It should be noted that the utility model is a steel bar cutting machine with a protective structure. When cutting the end of the steel bar, the handle 2 can be held by hand and the hydraulic shear body 1 can be carried by hand through the handle 4. Then, the shear assembly 6 is inserted and installed on the steel bar to be cut. At the same time, the cut part of the steel bar is placed between the fixing ring 9 and the first fixing rods 13 and the second fixing rods 18.

The movable cover 10 drives multiple groups of second fixing rods 18 to move to one side between the corresponding two first fixing rods 13, and makes the second connecting rod 19 between the two second fixing rods 18 move on the corresponding connecting screw 11. At the same time, the compression spring 20 on the outside of the connecting screw 11 is compressed toward the end block 17 at one end of the connecting screw 11, so that it can be adjusted according to the cutting length of the steel bar. Subsequently, the steel bar is cut by the handle 2 in cooperation with the external hydraulic station and the shearing assembly 6. Then, the cut steel bar fragments fall into the cavity composed of the fixing ring 9, the movable cover 10, and the multiple first fixing rods 13 and the second fixing rods 18, so as to prevent the steel bar fragments from splashing.
