Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a steel bar cutting machine for construction projects. Background Technology

[0002] Reinforcing steel bars have a wide range of applications, especially in the construction industry, where there is a large demand for them. When combined with concrete, reinforcing steel bars can better withstand external forces. Currently, some reinforcing steel coils are processed by operators in the production room, while others are directly transported to construction sites.

[0003] Existing rebar cutting machines first straighten the rebar, then cut it using a cutting machine behind the straightening device. Most existing rebar cutting machines that can control the cutting length use intelligent encoders to cut to the required length. This method is cumbersome to operate, and the rebar's elasticity can easily cause it to slip and spring back during cutting, leading to encoder deviations, affecting the output of the required rebar length, and resulting in unusable rebar and a higher likelihood of waste. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a steel bar cutting machine for construction projects, which solves the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a construction steel bar cutting machine, including a base, a feeding box fixedly connected to one side of the base surface, an mounting frame fixedly connected to the side of the base surface away from the feeding box, a spring device fixedly connected to one side of the mounting frame, a cutting blade fixedly connected to the side of the spring device away from the mounting frame, a connecting block fixedly connected to the surface of the cutting blade, a screw rotatably connected to the surface of the cutting blade, the end of the screw away from the cutting blade rotatably connected to the surface of the connecting block, and a limit block bolted to the middle surface of the screw.

[0008] Optionally, a fixing rod with a spring device is fixedly connected to one side of the mounting bracket. A limit hole is opened on the side of the fixing rod away from the mounting bracket. A spring is fixedly connected inside the fixing rod. A locking block is fixedly connected to one end of the spring. A compression rod is fixedly connected to the end of the locking block away from the spring. A sleeve is fitted onto the surface of the fixing rod. The side of the compression rod away from the locking block is fixedly connected to the inside of the sleeve. The outside of the sleeve is fixedly connected to the surface of the cutting blade. There are two spring devices, distributed vertically on the same side of the mounting bracket.

[0009] Optionally, the machine base has a discharge port at the cutting blade, and a first sliding groove is formed on the surface of the machine base. A first slider is slidably connected inside the first sliding groove. The side of the first slider away from the first sliding groove is fixedly connected to the bottom surface of the cutting blade. A second slider is slidably connected to the side of the first sliding groove away from the first slider. The other end of the second slider is fixedly connected to a limiting block. A second sliding groove is formed at the upper part of the mounting bracket. A third slider is slidably connected inside the second sliding groove. The other end of the third slider is fixedly connected to the upper surface of the cutting blade.

[0010] Optionally, a circular locking block is fixedly connected to one end of the screw, and the circular locking block is rotatably connected to the surface of the cutting blade.

[0011] This utility model provides a steel bar cutting machine for construction projects, which has the following beneficial effects:

[0012] 1. The steel bar cutting machine for this construction project uses a screw and a limiting block. When in use, the position of the limiting block can be adjusted by rotating the screw to achieve the effect of cutting the required length of steel bar. After the position of the limiting block is adjusted, the screw can be clamped by the cooperation of the clamping block and the slot to prevent the limiting device from sliding during machine operation, which would cause length deviation and affect the scrap rate of steel bars.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example

[0022] Please see Figures 1 to 5 This utility model provides a technical solution for a construction steel bar cutting machine, including a base 1. A feeding box 2 is fixedly connected to one side of the surface of the base 1. A mounting frame 3 is fixedly connected to the side of the surface of the base 1 away from the feeding box 2. A spring device 4 is fixedly connected to one side of the mounting frame 3. A cutting blade 5 is fixedly connected to the side of the spring device 4 away from the mounting frame 3. A connecting block 6 is fixedly connected to the surface of the cutting blade 5. A screw 16 is rotatably connected to the surface of the cutting blade 5. The end of the screw 16 away from the cutting blade 5 is rotatably connected to the surface of the connecting block 6. A limit block 7 is bolted to the middle surface of the screw 16.

[0023] Specifically, the mounting bracket 3 is used to fix the spring device 4 and the stabilizing cutter 5. The cutter 5 is fixedly connected to the connecting block 6, and a screw 16 is rotatably connected in the middle. A limit block 7 is bolted to the middle surface of the screw 16, so that the cutter 5 and the connecting block 6 can remain stationary when the screw 16 rotates. The limit block 7 moves back and forth along the thread of the screw 16, thereby achieving the effect of adjusting the cutting length. When the steel bar abuts against the limit block 7, the pressure from the rear feeding box 2 will cause the limit block 7 to move forward. At this time, the spring device 4 can effectively buffer the pressure. When the steel bar is cut, the tensile pressure received by the spring device 4 is released, so that the steel bar can quickly enter the cutter 5 for the next cut, thereby improving work efficiency.

[0024] Please see Figures 1 to 5A fixing rod 41 of a spring device 4 is fixedly connected to one side of the mounting bracket 3. A limit hole 44 is opened on the side of the fixing rod 41 away from the mounting bracket 3. A spring 42 is fixedly connected inside the fixing rod 41. A locking block 43 is fixedly connected to one end of the spring 42. A compression rod 45 is fixedly connected to the end of the locking block 43 away from the spring 42. A sleeve 8 is sleeved on the surface of the fixing rod 41. The side of the compression rod 45 away from the locking block 43 is fixedly connected to the inside of the sleeve 8. The outside of the sleeve 8 is fixedly connected to the surface of the cutting blade 5. There are two spring devices 4, which are distributed on the same side of the mounting bracket 3.

[0025] Specifically, when the reinforcing bar abuts against the limiting block 7, causing the spring device 4 to stretch, the compression rod 45 inside the fixed rod 41 stretches along with the cutting blade 5. The compression rod drives the spring 42 to stretch through the locking block 43. When stretched to the maximum distance, the cooperation between the locking block 43 and the limiting hole 44 can prevent the compression rod 45 from falling out of the fixed rod 41. When the compression rod 45 is stretched, it can drive the sleeve 8 to slide. The sleeve 8 can further make the movement of the compression rod 45 more stable.

[0026] Please see Figures 1 to 5 The base 1 has a discharge port 9 at the cutting blade 5. The surface of the base 1 has a first sliding groove 10. A first slider 11 is slidably connected inside the first sliding groove 10. The side of the first slider 11 away from the first sliding groove 10 is fixedly connected to the bottom surface of the cutting blade 5. A second slider 13 is slidably connected to the side of the first sliding groove 10 away from the first slider 11. The other end of the second slider 13 is fixedly connected to the limiting block 7. A second sliding groove 14 is provided at the upper part of the mounting bracket 3. A third slider 15 is slidably connected inside the second sliding groove 14. The other end of the third slider 15 is fixedly connected to the upper surface of the cutting blade 5.

[0027] Specifically, the first slider 11 is fixedly connected to the lower part of the cutting blade 5, and the second slider 13 is fixedly connected to the lower part of the limiting block 7. Both sliders are slidably connected to the first sliding groove 10. When the reinforcing bar moves against the limiting block 7, the limiting block 7 can move smoothly back and forth through the cooperation of the second slider 13 and the first sliding groove 10. The upper part of the cutting blade 5 is fixedly connected to the third slider 15, which is slidably connected to the second sliding groove 14 opened in the mounting bracket 3. When the cutting blade 5 moves, the sliders at the upper and lower ends can stabilize the cutting blade 5, so that the cutting blade 5 can move smoothly back and forth.

[0028] Please see Figures 1 to 5One end of the screw 16 is fixedly connected to a circular locking block 161, which is rotatably connected to the surface of the cutting blade 5. The end of the screw 16 away from the circular locking block 161 is fixedly connected to a rotating block 162. The surface of the rotating block 162 is provided with teeth, and a locking block 17 is sleeved on the surface of the rotating block 162. The inside of the locking block 17 is provided with a hole that matches the teeth. A buckle 171 is fixedly connected to one side of the locking block 17. There are two buckles 171, which are symmetrically arranged on both sides of the locking block 17. The other end of the locking block 17 is fixedly connected to a lever 172. The surface of the connecting block 6 is provided with several locking grooves 18, which match the shape of the buckles 171. The several locking grooves 18 are arranged in a circular array with the bolt opening as the center.

[0029] Specifically, the screw 16 and the clamping block 17 are both independent structures. The screw 16 is rotatably connected to one side of the cutting blade 5 via a circular clamping block 161, and the other side is rotatably connected to the inside of the connecting block 6 via the threaded area of ​​the screw 16. After adjusting the position of the limiting block 7 by rotating the screw 16 via the rotating block 162, the clamping block 17 is fitted onto the surface of the rotating block 162. The surface of the rotating block 162 is provided with teeth, and the inside of the clamping block 17 has holes that fit with the teeth. Then, the buckle 171 is engaged with the connecting block. The screw 16 is secured in the groove 18 on the 6-sided surface, which allows the screw to be engaged. The meshing teeth allow for a better and more stable connection between the rotating block 162 and the clamping block 17, enabling the clamping block 17 to secure the rotating block 162 effectively. Several clamping grooves 18 are provided, allowing two symmetrical buckles 171 to flexibly engage in different positions within the clamping grooves 18, increasing the accuracy of length adjustment. The cooperation between the buckles 171 and the clamping grooves 18 effectively secures the screw 16, preventing the screw 16 from rotating during use and causing length deviation.

[0030] In use, rotating the rotating block 162 drives the screw 16 to rotate. The rotation of the screw causes the limiting block 7 to move back and forth. During this movement, the second slider 13 below the limiting block 7 moves along the first groove, ensuring that the limiting block 7 can move stably back and forth without shifting left or right when the screw 16 rotates. After adjusting to the desired cutting length, the clamping block 17 is fitted onto the top of the rotating block 162, and the latch 171 is inserted into the clamping groove 18 to clamp the screw 16, preventing it from slipping during operation. The deviation in cutting length is caused by the screw being fixed. The steel bar to be processed is placed into the feeding box 2 and straightened. Then the steel bar enters the cutting blade 5 and extends continuously until it hits the limiting block 7. At this time, the pressure causes the steel bar to hit the limiting block 7 and pull the spring device 4. The cutting blade 5 then quickly cuts the steel bar. The cut steel bar falls along the discharge port 9. At this time, because the steel bar is cut, the tension pressure on the spring device 4 is released and it quickly springs back to its original position, thereby quickly loading the steel bar behind into the cutting blade 5, thus performing reciprocating cutting work.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
