Description

Technical Field

[0001] This utility model relates to the technical field of rebar cutting devices, and in particular to a rebar cutting device with a protective structure. Background Technology

[0002] In the construction industry, cutting rebar is an extremely common and frequent processing operation. Currently, handheld rebar cutters such as angle grinders equipped with cutting discs or simple fixed cutting devices are commonly used on construction sites. When these devices cut rebar, the grinding wheel rubs violently against the rebar, generating a large amount of high-temperature sparks and hot metal oxide debris, which are sprayed and splashed in all directions.

[0003] Existing commonly used equipment generally lacks effective and active spark and debris collection and protection structures. This unrestrained splashing poses a direct safety threat to operators. The splashing sparks can easily burn the skin of personnel or ignite surrounding flammable materials, posing a fire hazard. Secondly, the diffused metal dust and debris will pollute the working environment, affect the operator's visibility, and are difficult to clean. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a steel bar cutting device with a protective structure that can effectively avoid sparks, improve the safety of on-site operators, and prevent burns and fire hazards in order to overcome the shortcomings mentioned above.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a steel bar cutting device with a protective structure, including a base and a cutting mechanism installed on the base. A rotating component is installed on the base, and the cutting mechanism is installed on the rotating component. The cutting mechanism is rotatably installed on the base through the rotating component. A gathering component is installed on the base below the cutting mechanism, and a pressing mechanism for positioning the steel bar is installed below the cutting mechanism.

[0006] Furthermore, the rotating assembly includes a rotating seat fixed to the middle of the top of the base, and a platform located on the rear side of the top of the base, with a fixed seat hinged to the upper side of the rotating seat.

[0007] Furthermore, the cutting mechanism includes a motor and a transmission shaft.

[0008] Furthermore, the gathering component includes a water box installed at the top of the base below the saw blade. The top of the water box is open, and a baffle is fixedly installed on the front side of the opening end of the water box. Two through slots are symmetrically opened on both sides of the water box.

[0009] Furthermore, a water guide seat is installed on the upper side of the water box, and several atomizing heads extending into the water box are installed equidistantly on both sides of the water guide seat along its length direction. A water supply pipe connected to an external water supply pump is installed on the water guide seat.

[0010] Furthermore, anti-splash rings are installed on the inner side of the water box at the two inner ports of the through grooves, a slope is opened at the bottom of the inner cavity of the water box, and a slag outlet is installed on the water box at the bottom of the slope.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-5 This embodiment provides a rebar cutting device with a protective structure, including a base 1 and a cutting mechanism 2 installed on the base 1. A rotating component 3 is installed on the base 1, and the cutting mechanism 2 is installed on the rotating component 3. The cutting mechanism 2 is rotatably installed on the base 1 through the rotating component 3. A gathering component 5 is installed on the base 1 below the cutting mechanism 2, and a pressing mechanism 6 for positioning the rebar is installed below the cutting mechanism 2.

[0016] The following section will explain the specific setup and function of the cutting mechanism 2, the rotating component 3, the gathering component 5, and the pressing mechanism 6.

[0017] In this embodiment: the rotating assembly 3 includes a rotating seat 31 fixed at the middle of the top of the base 1, and a frame 33 located at the rear of the top of the base 1. A fixed seat 32 is hinged to the upper side of the rotating seat 31. Specifically, the cutting mechanism 2 includes a motor 21 and a transmission shaft 22. The motor 21 is fixedly installed on the rear side of the top of the fixed base 32, and the transmission shaft 22 is rotatably installed on the front side of the top of the fixed base 32. A saw blade 221 is rotatably installed on the corresponding side of the transmission shaft 22. The output shaft of the motor 21 is connected to the transmission shaft 22 through a transmission pair 23. The effect achieved by the above components is as follows: the rotating assembly 3 provides a stable fulcrum for the cutting mechanism 2, so that the cutting mechanism 2 can rotate smoothly up and down around the rotating seat 31. When it is necessary to cut the steel bar, the cutting mechanism 2 rotates downward as a whole, and the motor 21 drives the saw blade 221 to rotate at high speed, thereby cutting the steel bar.

[0018] In this embodiment: the gathering component 5 includes a water box 51 installed at the top of the base 1 below the saw blade 221. The top of the water box 51 is open. A baffle 52 is fixedly installed on the front side of the opening end of the water box 51. Two through slots 54 are symmetrically opened on both sides of the water box 51. Specifically, a water guide seat 53 is installed on the upper side of the water box 51. Several atomizing heads 532 extending into the water box 51 are installed on both sides of the water guide seat 53 at equal intervals along its length. A water supply pipe 531 connected to an external water supply pump is installed on the water guide seat 53. Specifically, splash guards 541 are installed on the inner side of the water box 51 at the inner ports of the two through slots 54, and a ramp 511 is provided at the bottom of the inner cavity of the water box 51. A slag outlet 55 is installed on the water box 51 at the bottom of the ramp 511. The effects achieved by the above components are as follows: the water box 51 is located directly below the saw blade 221, and its opening and the front baffle 52 can effectively guide the high-temperature sparks and metal debris splashed during cutting into the box. The through slots 54 on both sides allow steel bars to pass through for cutting. At the same time, the anti-splash ring 541 on its inner side extends into the water box 51 to prevent the liquid in the box from overflowing outward through the through slot 54. The water guide seat 53 sprays water mist through the atomizing head 532, which can quickly cool the sparks and debris entering the box, effectively suppress dust and eliminate fire hazards. The slope 511 designed at the bottom of the water box facilitates the collection of debris and wastewater, which are then discharged through the slag outlet 55 for easy cleaning.

[0019] In this embodiment: the pressing mechanism 6 includes a side plate 61 fixedly installed on one side of the fixed base 32. A guide groove 62 is opened through the top of the side plate 61. A slide rod 63 is slidably installed inside the guide groove 62. A pressing base 64 is installed at the bottom of the slide rod 63. A spring 65 is sleeved on the outside of the slide rod 63. The two ends of the spring 65 abut against the pressing base 64 and the side plate 61 respectively. The effect achieved by the above components is as follows: the side plate 61 is connected to the fixed seat 32 of the cutting mechanism 2, so that it can move synchronously with the cutting mechanism 2. When the cutting mechanism 2 rotates downward, the pressure seat 64, under the preload of the spring 65, slides downward along the guide groove 62 through the slide rod 63, contacting and pressing the steel bar onto the base 1 before the saw blade 221. This process ensures that the steel bar remains stable throughout the cutting process, effectively preventing the cutting position from shifting, uneven cut, and safety accidents caused by the steel bar rolling, tilting, or bouncing under force.

[0020] Working principle: The operator starts the motor 21, and the power is transmitted to the transmission shaft 22 through the transmission pair 23, driving the saw blade 221 to rotate at high speed to prepare for cutting. The operator manually presses down the fixed seat 32, so that the entire cutting mechanism 2 rotates smoothly downward with the rotating seat 31 as the hinge axis through the rotating component 3. The high-speed rotating saw blade 221 then approaches and cuts the steel bar placed on the base 1. The holding mechanism 6 is fixed to the fixed base 32, which rotates synchronously with the cutting mechanism, via the side plate 61. When the cutting mechanism is pressed down, the holding mechanism 6 moves down synchronously. Under the continuous pre-tightening force of the spring 65, the pressure base 64 contacts the steel bar before the saw blade 221 through the guide of the slide rod 63 along the guide groove 62, and firmly presses it onto the bearing surface of the base 1. This process ensures that the position of the steel bar is fixed throughout the cutting process, avoiding rolling, bouncing or tilting. The hot sparks and debris generated during cutting splash downwards and laterally. The water box 51, located directly below the saw blade, intercepts most of the splashes and guides them into the box through its top opening and front baffle 52. The water supply is connected to the water guide seat 53 through the water supply pipe 531, and the atomizing head 532 distributed along it sprays fine water mist into the water box 51. The water mist can instantly cool the high-temperature debris and sparks, greatly suppress dust generation, and completely eliminate fire hazards. The inside of the through groove 54 through which the steel bars pass is equipped with a splash guard 541 to prevent the liquid inside the box from overflowing. The cooled residue and wastewater are collected at the slag outlet 55 along the slope 511 designed at the bottom of the water box 51, which is convenient for unified cleaning and keeps the inside of the equipment clean. After the cutting is completed, the operator lifts the cutting mechanism, the saw blade 221 leaves the workpiece, and the holding mechanism 6 is lifted by the spring 65 to release the steel bar. The equipment returns to standby mode, and the cut steel bar can be taken out and prepared for the next cutting cycle.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these are within the scope of protection of the present invention.
