Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a steel bar cutting device. Background Art
[0002] During the construction process, a large number of steel bars are needed. The raw materials of a single steel bar are generally long and need to be cut according to the required length by a steel bar cutting tool. However, the existing steel bar cutting tool requires the steel bar to be placed on a limit seat and then pressed by a cover plate. Each time the steel bar is cut, the cover plate needs to be removed to replace the steel bar, which is a large workload. For example, the existing patent number CN216324808U is a steel bar cutting device for road and bridge construction, which discloses a base and a tool that can cut steel bars. A limit seat and a rotating shaft are set on the side of the base away from the motor, and a cover plate is connected to one side of the rotating shaft. The steel bar is placed in the middle of the top of the limit seat, and the limit block is used to dock with the limit groove, so as to facilitate the limit of the steel bar. When installing and removing the steel bar, the steel bar cutting device needs to manually remove the cover plate each time. Utility Model Content
[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a steel bar cutting device.
[0004] The technical solution of this utility model is as follows:
[0005] A steel bar cutting device comprises a mounting frame arranged on a reference plane, the mounting frame having a bottom plate, a first base arranged on the bottom plate, a clamping seat arranged on the first base, the clamping seat connected to the top of the first base through a first elastic member, a first arc groove is formed on the upper end surface of the first base, a second arc groove corresponding to the first arc groove is formed on the lower end surface of the clamping seat, a cutting knife is vertically arranged above one side of the first base, the moving direction of the cutting knife is perpendicular to and intersects with the axial direction of the first arc groove, and a lifting assembly is connected to the upper part of the cutting knife;
[0006] A lifting rod is arranged on the upper part of the cutting knife, a lifting frame is arranged on the upper part of the clamping seat, and the lifting rod is penetrated in the lifting frame.
[0007] The cutting knife can move vertically up and down driven by the lifting assembly. The steel bar is horizontally arranged on the first base, located between the first arc groove and the second arc groove, and is clamped on the first base by the clamping seat. The cutting knife can cut the steel bar when it moves downward, and the cutting knife moves upward to drive the lifting rod to move upward. When the cutting knife moves up to a certain position, the lifting rod will push the lifting frame upward, thereby driving the clamping seat to move up. The clamping seat is away from the first base, and the steel bar does not clamp the steel bar after it is cut off, which is convenient for the staff to replace the steel bar or adjust the position of the steel bar to be cut off on the first base and continue to cut it. The operation is relatively simple, which reduces the work intensity of the staff and improves the cutting efficiency of the steel bar.
[0008] The above-mentioned elastic member can play the role of tightening the clamping seat to the first base, but the tightening effect of the elastic member is limited. In order to further clamp the steel bar to the first base through the clamping seat, a counterweight seat is fixed above the clamping seat, and the lifting frame is set on the counterweight seat. The dead weight of the counterweight seat cooperates with the tightening force of the elastic member to further fix the steel bar on the clamping seat and the first base.
[0009] The moving range of the above-mentioned lifting rod is that a vertically arranged long groove is opened on the counterweight seat, and the long groove is arranged to be open on the side close to the cutting knife. The lifting rod is located in the long groove, and the lifting frame is arranged above the long groove, and the two ends of the lifting frame are respectively connected to the two sides of the long groove. The length direction of the lifting frame is arranged perpendicular to the length direction of the lifting rod, so that when the lifting rod moves upward, it can drive the lifting frame to move upward, thereby driving the counterweight seat and the clamping seat to move up at the same time.
[0010] The above-mentioned first elastic member is a tension spring, which is vertically arranged on the outside of the first base. There are multiple tension springs, which are distributed below the clamping seat. The upper end of the tension spring is fixedly connected to the lower end of the clamping seat, and the lower end of the tension spring is fixedly connected to the bottom plate. In the normal state of the tension spring, the second arc groove of the clamping seat is close to the upper end surface of the first base, and can clamp steel bars of different types.
[0011] According to the above structure, in order to reduce the shaking of the steel bars during the cutting process, which may cause accidental injury to the workers, a second base is provided on the side of the cutting knife away from the first base. The steel bars on the second base are the cut-off parts. The second base has the same structure as the first base and is symmetrically arranged. Therefore, the steel bars can be placed on the first base and the second base at the same time.
[0012] The above-mentioned second base has a third arc groove, a guide block is arranged above the third arc groove, and the lower end surface of the guide block is provided with a fourth arc groove corresponding to the third arc groove. The steel bars are placed on the first arc groove and the third arc groove, and are located between the third arc groove and the fourth arc groove. The second base and the guide block can prevent the cut part of the steel bar from moving to one side when it breaks, and the displacement of the cut steel bar can be limited between the second base and the guide block, thereby reducing the phenomenon of accidental injury to the staff.
[0013] The guide block is connected to the second base in such a manner that the guide block is connected to the second base via a second elastic member.
[0014] The guide block does not have to be in close contact with the second base. Therefore, the second elastic member is a compression spring, which is located on the outside of the second base. A channel for accommodating steel bars can be formed between the third arc groove and the fourth arc groove, thereby reducing the phenomenon of the end of the cut steel bar moving quickly to one side.
[0015] In order not to affect the lifting rod moving down with the cutting knife and not to affect the cutting of the steel bar by the cutting knife, the length of the long groove in the vertical direction is greater than the maximum moving distance of the cutting knife.
[0016] If the steel bar is too close to the bottom plate, for example, the steel bar is set parallel to the bottom plate, and the vertical distance between the steel bar and the bottom plate is 1cm, or it affects the downward movement of the cutting knife to cut the steel bar, the steel bar may not be cut completely. For this reason, the distance between the lowest point of the first arc groove and the bottom plate is set to 5-20cm, and a certain downward cutting space is reserved for the cutting knife to cut the steel bar, so as to achieve the effect of completely cutting the steel bar.
[0017] The beneficial effect of the utility model is that a large amount of steel bars are needed in the construction process. Therefore, the raw material workload of cutting the steel bars is large. In order to reduce the operating steps of cutting the steel bars and improve the efficiency of steel bar cutting, a first base and a clamping seat are provided. The steel bars are provided between the first base and the clamping seat. The clamping seat can clamp the steel bars, which is convenient for the cutting knife to quickly cut the fixed steel bars, and reduces the shaking of the steel bars during cutting, which affects the safety of the workers. The cutting knife moves downward under the action of the lifting component. During the downward movement, the lifting rod follows the cutting knife to move downward. The downward movement of the lifting rod is located in the lifting frame. After the cutting knife moves down to the lowest point to cut the steel bars, the lifting component drives it to move up to a certain position, and can lift it up through the lifting rod, thereby driving the clamping seat away from the first base, and does not clamp the cut steel bars, which is convenient for removing the steel bars or moving the remaining steel bars to be cut on the first base to continue cutting. Compared with the prior art, the manual operation steps of steel bar cutting are reduced, the safety of the operating workers is improved, and the cutting efficiency of the steel bars is improved.

[0026] Among them, Figure 2 As shown, a lifting rod 10 is provided on the side of the cutting knife 8 away from the first base 2, and a lifting frame 11 is provided on the upper part of the clamping seat 4, and the lifting rod 10 is inserted into the lifting frame 11. The moving range of the above-mentioned lifting rod 10 is that a vertically arranged long groove 1201 is provided on the counterweight seat 12, and the long groove 1201 is set as an opening near the side of the cutting knife 8, the lifting rod 10 is located in the long groove 1201, and the lifting frame 11 is set above the long groove 1201, and the two ends of the lifting frame 11 are respectively connected to the two sides of the long groove 1201, and the length direction of the lifting frame 11 is perpendicular to the length direction of the lifting rod 10, so that when the lifting rod 10 moves up, it can drive the lifting frame 11 to move up, and then drive the counterweight seat 12 and the clamping seat 4 to move up at the same time. In order not to affect the lifting rod 10 to move down with the cutting knife 8 and not to affect the cutting of the steel bar by the cutting knife 8, the length of the long groove 1201 along the vertical direction is greater than the maximum moving distance of the cutting knife 8.
[0027] like Figure 3 and Figure 4As shown, the first elastic member 6 is a tension spring, which is vertically arranged outside the first base 2. There are multiple tension springs, which are distributed below the clamping seat 4, and the upper end of the tension spring is fixedly connected to the lower end of the clamping seat 4, and the lower end of the tension spring is fixedly connected to the bottom plate 101. Under the normal state of the tension spring, the second arc groove 401 of the clamping seat 4 is close to the upper end surface of the first base 2, and can clamp different types of steel bars. The elastic member can play a role in clamping the clamping seat 4 against the first base 2, but the tensioning effect of the elastic member is limited. In order to further clamp the steel bar on the first base 2 through the clamping seat 4, a counterweight seat 12 is fixedly arranged above the clamping seat 4, and a lifting frame 11 is arranged on the counterweight seat 12. The counterweight seat 12 cooperates with the elastic member to further fix and clamp the steel bar on the clamping seat 4 and the first base 2.
[0028] According to the above structure, the beneficial effects that can be achieved by the utility model are as follows: a large number of steel bars are needed in the construction process, so the raw material workload of cutting the steel bars is large. In order to reduce the operation steps of cutting the steel bars and improve the efficiency of steel bar cutting, a first base 2 and a clamping seat 4 are provided, and the steel bars are provided between the first base 2 and the clamping seat 4. The clamping seat 4 can clamp the steel bars, which is convenient for the cutting knife 8 to quickly cut the fixed steel bars, and reduce the shaking of the steel bars during cutting, which affects the safety of the staff. The cutting knife 8 moves downward under the action of the lifting component 9. During the downward movement, the lifting rod 10 follows the cutting knife 8 to move downward. The downward movement of the lifting rod 10 is located in the lifting frame 11. After the cutting knife 8 moves down to the lowest point to cut the steel bars, the lifting component 9 drives it to move up to a certain position, and can be lifted by the lifting rod 10, thereby driving the clamping seat 4 away from the first base 2, and the cut steel bars are not clamped, which is convenient for removing the steel bars or moving the remaining steel bars to be cut on the first base 2, and continuing to cut. Compared with the prior art, the manual operation steps of steel bar cutting are reduced, and the cutting efficiency of steel bars is improved.
[0029] In order to reduce the shaking of the steel bar during the cutting process, which may cause accidental injury to the staff, a second base 3 is provided on the side of the cutting knife 8 away from the first base 2. The steel bar on the second base 3 is the cut-off part. The second base 3 has the same structure as the first base 2 and is symmetrically arranged. Therefore, the steel bar can be placed on the first base 2 and the second base 3 at the same time. The second base 3 has a third arc groove 301, and a guide block 5 is arranged above the third arc groove 301. The lower end surface of the guide block 5 is provided with a fourth arc groove 501 corresponding to the third arc groove 301. The steel bar is placed on the first arc groove 201 and the third arc groove 301, and is located between the third arc groove 301 and the fourth arc groove 501. The second base 3 and the guide block 5 can prevent the cut-off part of the steel bar from moving to one side when it breaks. The displacement of the cut-off steel bar can be limited between the second base 3 and the guide block 5, thereby reducing the accidental injury to the staff. The guide block 5 is connected to the second base 3 in the manner that the guide block 5 is connected to the second base 3 through the second elastic member 7. The guide block 5 does not have to be in close contact with the second base 3. Therefore, the second elastic member 7 is a compression spring, which is located on the outside of the second base 3. A channel for accommodating steel bars can be formed between the third arc groove 301 and the fourth arc groove 501, thereby reducing the phenomenon of the end of the cut steel bar moving quickly to one side.
[0030] Finally, if the steel bar is too close to the bottom plate 101, for example, the steel bar is arranged parallel to the bottom plate 101, and the vertical distance between the steel bar and the bottom plate 101 is 1 cm, or it affects the downward movement of the cutting knife 8 to cut the steel bar, the steel bar may not be cut completely. For this reason, the lowest point of the first arc groove 201 is set to a distance of 5-20 cm from the bottom plate 101, so as to reserve a certain downward cutting space for the cutting knife 8 to cut the steel bar, thereby achieving the effect of completely cutting the steel bar.
