[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1 and Figure 2 A rebar cutting machine includes a support plate 1 with a protrusion at the bottom that can be fixed to an external mechanism to provide support for the support plate 1. A circular saw 2 for cutting rebar is provided above the support plate 1. A horizontally movable rectangular plate 3 is provided at the bottom of the support plate 1. An abutment plate 4 is fixedly connected to the top of one end of the rectangular plate 3.
[0025] The top of the rectangular plate 3 has a scale, which makes it easy to control the movement distance of the rectangular plate 3. The movement distance of the rectangular plate 3 can be adjusted according to the different lengths of steel bars to be cut.
[0026] The shape of the contact plate 4 includes, but is not limited to, a circle, a rectangle or a regular polygon. The contact plate 4 is used to press against one end of the steel bar when cutting the steel bar. The support plate 1 is provided with a through groove 101 for the movement of the circular saw 2. The saw blade part at the bottom of the circular saw 2 can move along the through groove 101.
[0027] like Figure 3 and Figure 4 A positioning plate 301 is fixedly connected to the bottom of the rectangular plate 3. A fixing clamp 5 and a locking mechanism 6 are respectively provided on both sides of the positioning plate 301. The fixing clamp 5 is fixed to the bottom of the rectangular plate 3. The locking mechanism 6 includes a support block 601 fixed to the bottom of the support plate 1. A locking screw 602 is threadedly connected to the support block 601. A movable clamp 603 is rotatably connected to one end of the locking screw 602. The movable clamp 603 and the fixing clamp 5 are located on both sides of the positioning plate 301, which can clamp the positioning plate 301 and prevent the positioning plate 301 and the rectangular plate 3 from shifting.
[0028] like Figure 1 The bottom rectangular plate 3 of the support plate 1 has guide grooves 7 on both sides. The bottom of the support plate 1 and both sides of the guide grooves 7 are fixedly connected to guide slide plates 8. The guide grooves 7 and guide slide plates 8 are slidably connected, so that the guide slide plates 8 can provide support for the rectangular plate 3 while ensuring the sliding of the rectangular plate 3.
[0029] like Figure 2 A support frame 9 is fixedly connected to the support plate 1. A rectangular groove is provided on the support frame 9. A limiting shaft 901 is fixedly connected in the rectangular groove. A sliding block 10 is slidably connected to the limiting shaft 901. While providing support for the sliding block 10, it ensures that the sliding block 10 can only move along the direction of the limiting shaft 901. The bottom of the sliding block 10 is fixedly connected to the circular saw 2 through a connecting rod, which is used to drive the circular saw 2 to move together.
[0030] like Figure 1 and Figure 2 An electric telescopic rod 11 is fixedly connected to the support plate 1, and a protruding plate 12 is fixedly connected to the sliding block 10. The telescopic end of the electric telescopic rod 11 and the protruding plate 12 are slidably connected. Both the electric telescopic rod 11 and the circular saw 2 are connected to an external power source and have corresponding external control switches.
[0031] like Figure 1 The support plate 1 is fixedly connected with a linear array of support blocks 13. The center of the top of the support block 13 is provided with an arc-shaped concave shape for supporting the reinforcing bars. The support block 13 can provide support for the reinforcing bars.
[0032] like Figure 1 A fixed frame 14 is fixedly connected to the top of the support plate 1. A pressing cylinder 15 is fixedly connected to the fixed frame 14. The pressing cylinder 15 is existing technology and is equipped with a power source. A horizontal plate 16 is fixedly connected to the telescopic end of the pressing cylinder 15. Multiple pressing plates 17 are fixedly connected to the bottom of the horizontal plate 16. The bottom of the pressing plate 17 has an arc-shaped concave shape, which can be adapted to the reinforcing bars and press the reinforcing bars. The pressing plates 17 and the support blocks 13 are staggered and used to press the reinforcing bars of the support blocks 13.
[0033] The working principle of the rebar cutting machine provided by this utility model is as follows:
[0034] When it is necessary to cut the steel bars, rotate the locking screw 602 clockwise to separate the movable clamping plate 603 and the positioning plate 301. At this time, the rectangular plate 3 can be moved horizontally to adjust the straight distance between the contact plate 4 and the circular saw when cutting the steel bars. After the adjustment is completed, rotate the locking screw 602 counterclockwise to move the movable clamping plate 603 closer to the positioning plate 301, and the fixed clamping plate 5 clamps the positioning plate 301 from both sides to fix the rectangular plate 3 and the contact plate 4.
[0035] Next, place the reinforcing bar on the support block 13 and press one end of the reinforcing bar against the contact plate 4. The pressing cylinder 15 extends and drives the transverse plate 16 and the pressing plate 17 to move down to press and fix the reinforcing bar. Finally, start the circular saw 2. The electric telescopic rod 11 retracts and drives the circular saw 2 to cut the reinforcing bar. Then it extends again to reset the circular saw 2.
[0036] The clamping cylinder 15 retracts, causing the clamping plate 17 to move upward. At this time, the steel bar can be pushed so that one end of the steel bar touches the contact plate 4. Then, the clamping cylinder 15 extends, causing the clamping plate 17 to move downward, fixing the steel bar. The circular saw 2 then moves to cut the steel bar. By repeating this step, the steel bar can be cut into multiple pieces of the same length but different lengths.
[0037] Compared with related technologies, the rebar cutting machine provided by this utility model has the following beneficial effects:
[0038] This invention ensures that the same length of steel bar is cut each time by pressing one end of the steel bar against the contact plate 4 before each cutting, and then moving the pressure plate 17 downward to fix the steel bar by extending and retracting the pressure cylinder 15. This eliminates the need for measuring or marking the steel bar. At the same time, by adjusting the position of the rectangular plate 3 horizontally, the straight distance between the circular saw 2 and the contact plate 4 when cutting the steel bar can be adjusted, and the steel bar can be cut to different lengths as needed.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
