Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a steel bar cutting device for building construction. Background Technology

[0002] In the construction industry, steel bars, as the core reinforcing material in concrete structures, directly affect the stability and safety of engineering structures through their processing quality. With the continuous expansion of infrastructure construction and the rapid development of the construction industry in my country, the steel bar processing industry has also ushered in new opportunities and challenges. Modern construction projects have increasingly higher requirements for the specifications and precision of steel bars, and different parts of the project often require steel bar components of different lengths and specifications, which places higher demands on steel bar processing equipment.

[0003] Most widely used rebar cutting equipment currently employs a single cutting unit design, which has certain limitations in practical applications. When a single rebar needs to be cut into multiple segments of different lengths, traditional equipment must perform multiple repetitive operations, including repositioning, clamping, and cutting. This process is inefficient and prone to dimensional errors due to repeated clamping. Furthermore, adjusting the cutting specifications requires replacing molds or readjusting the equipment, which is time-consuming, labor-intensive, and affects construction progress. To address these issues, we provide a rebar cutting device for building construction. Utility Model Content

The steel bar cutting device includes a fixing mechanism and a feeding mechanism fixedly mounted on the fixing mechanism. The feeding mechanism has a guiding mechanism at its outlet end, and the fixing mechanism has three spaced-apart cutting mechanisms on one side of the guiding mechanism at its top. The fixing mechanism includes a fixing plate, and the guiding mechanism includes a guide plate. The guide plate has a V-shaped groove with a width significantly greater than its depth. The V-shaped groove has two vertical cut surfaces along the feeding direction, a first cut surface and a second cut surface. The first cut surface extends vertically downwards from the edge of the grooved plate, and the second cut surface extends downwards from the edge of the grooved plate and inclined downstream in the steel bar feeding direction, forming an asymmetrical structure where the second cut surface is inclined. This structure provides support for the steel bar during cutting and prevents springback and jamming.

[0006] The present invention is further configured such that the cutting grooves are correspondingly arranged one-to-one with the cutting mechanisms, a first through shaft and a second through shaft are provided through the inside of the guide plate, a first sliding column and a second sliding column are provided between the fixed plate and the feeding mechanism, the first through shaft is rotatably connected between the fixed plate and the feeding mechanism, the first sliding column is fixedly arranged on the top of the guide plate, the second sliding column is fixedly connected between the fixed plate and the feeding mechanism, the second through shaft is slidably connected between the fixed plate and the feeding mechanism, a push plate is slidably sleeved between the first sliding column and the second sliding column, and a rope drive assembly is provided on one side of the guide plate, the rope extending from the rope drive assembly is fixedly connected to the push plate.

[0007] The present invention is further configured such that the fixing mechanism includes a fixing platform, the fixing plate is fixedly connected to the top of the fixing platform, an electric telescopic rod base is fixedly installed on the top of the fixing platform, an electric telescopic rod is hinged on the electric telescopic rod base, a hinged support is fixedly installed on the lower surface of the guide plate, and the output end of the electric telescopic rod is hinged to the hinged support.

[0008] The present invention is further configured such that the rebar feeding mechanism and the fixing plate are provided with an arc-shaped groove on the side near the guide plate, the two ends of the second through shaft and the second sliding column are slidably disposed in the arc-shaped groove, and the rebar outlet of the rebar feeding mechanism is in contact with the fixing plate.

[0009] The present invention is further configured such that the cable drive assembly includes a motor base fixedly mounted on one side of the guide plate, a winding motor fixedly mounted on the top of the motor base, a take-up reel fixedly connected to the output shaft of the winding motor, and the movable end of the wire rope wound on the take-up reel fixedly connected to the push plate.

[0010] The present invention is further configured such that the cutting mechanism includes a shearing support plate fixedly mounted on the top of the fixed platform, a T-slot is provided on the shearing support plate, a horizontal slide plate is slidably mounted inside the T-slot, four diagonal tie rods are rotatably mounted on the horizontal slide plate, the cutting mechanism also includes two shearing arms, each of the two shearing arms is fixedly mounted with interlocking shearing clamps, a shearing hinge support is fixedly mounted on the shearing arm, and one end of the diagonal tie rod is hinged to the corresponding shearing hinge support.

[0013] This utility model has the following beneficial effects: 1. By setting up a guiding mechanism and three spaced-apart cutting mechanisms in cooperation, when the reinforcing bar is conveyed to the guide plate of the guiding mechanism by the reinforcing bar feeding mechanism, it can simultaneously pass through the three cutting slots and be operated by the corresponding cutting mechanisms. This structure realizes the synchronous multi-segment fixed-length cutting of a single reinforcing bar, solving the problem that traditional cutting devices cannot complete the synchronous cutting of multiple specifications of reinforcing bars at one time, thus improving construction efficiency and cutting accuracy.

[0014] 2. This utility model adopts an adjustment structure in which an electric telescopic rod drives the guide plate to rotate around the through shaft. The tilt angle of the guide plate relative to the fixed plate can be dynamically adjusted by the telescopic movement of the electric telescopic rod, thereby precisely controlling the conveying interval and cutting length of the reinforcing bars. This adjustment process is flexible, continuous, and controllable, solving the drawbacks of fixed cutting specifications and cumbersome adjustments in traditional equipment. It enables a single piece of equipment to quickly adapt to complex and ever-changing construction needs, improving the equipment's versatility and automation level. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] For a specific implementation example, please refer to Implementation Example 1. Figures 1-5This utility model relates to a rebar cutting device for building construction, comprising a fixing mechanism 1, a rebar feeding mechanism 2, and a guiding mechanism 3. The fixing mechanism 1 includes a fixing platform 102 and a fixing plate 101 vertically fixed thereon. The rebar feeding mechanism and the fixing plate have arc-shaped grooves on the side near the guiding plate. The two ends of the second through shaft and the second sliding column are slidably disposed in the arc-shaped grooves. The rebar outlet of the rebar feeding mechanism is in contact with the fixing plate. The guiding mechanism 3 includes a guiding plate 301. The guiding plate 301 has three V-shaped grooves and a cutting groove 302 along the rebar feeding direction. The first through shaft 303 and the second sliding column pass through the interior of the guiding plate 301. The first through shaft 303 is rotatably connected to the fixed plate 101 and the housing 201 at both ends. The second through shaft 304 is placed in the arc groove of the fixed plate 101 and the housing 201 at both ends and can slide and rotate along the arc groove. The fixed plate 101 and the housing 201 are provided with a first sliding column 305 and a second sliding column 306. The push plate 307 is slidably provided between the two sliding columns. The push plate 307 is fixedly connected to the free end of the wire rope of the cable drive assembly. The fixed platform 102 is hinged with an electric telescopic rod 308. The output end of the electric telescopic rod 308 is hinged to the hinge support on the lower surface of the guide plate 301.

[0029] The operation process of this embodiment is as follows: The reinforcing bar enters the reinforcing bar feeding mechanism through the front inlet of the feeding mechanism 2, and is smoothly fed towards the guide plate 301 at a constant speed (this feeding mechanism is existing technology, so it will not be described in detail here). After the front end of the reinforcing bar leaves the reinforcing bar outlet of the feeding assembly mounting frame, it enters the V-shaped guide groove on the guide plate 301 corresponding to the reinforcing bar outlet. As the reinforcing bar continues to move forward, its front end eventually contacts the push plate 307 that is slidably sleeved on the first sliding column 305 and the second sliding column 306, pushing the push plate 307 to slide away from the feeding mechanism 2 along the sliding column. The push plate 307 drives the steel wire rope fixedly connected to it to stretch. When the push plate 307 completely passes the cutting groove 302 on the side close to the fixed plate 101, the system determines that the length of the steel wire rope stretched has reached the preset value, that is, it determines that the reinforcing bar has been accurately fed to the predetermined cutting position. The steel feeding assembly then stops feeding, and the device enters the waiting-to-cut state, preparing for subsequent multi-segment synchronous cutting operations.

[0030] For a specific embodiment two, please refer to Figures 6-9Based on the first specific embodiment, the steel bar cutting device for construction in this utility model further includes three cutting mechanisms 4 and a blanking mechanism 5. Each cutting mechanism 4 includes a shearing support plate 401, on which a T-slot 402 and four vertical slots 407 are formed. A horizontal sliding plate 403 is slidably disposed within the T-slot 402, and four rotating shafts 404 are rotatably disposed on the horizontal sliding plate 403. The cutting mechanism 4 also includes two shearing arms 405, on which staggered shearing clamps 406 are fixedly disposed respectively. A shearing hinge support is fixedly installed, and the other end of the rotating shaft 404 is rotatably connected to the shearing hinge support. The shearing rotating shaft passes through the shearing hinge support, and a vertical slider 408 is fixedly connected to the shearing rotating shaft. The vertical slider 408 is slidably disposed in the vertical groove 407. A hydraulic cylinder 409 is fixedly installed on the shearing support plate 401. The output end of the hydraulic cylinder 409 is fixedly connected to a fixed support on the horizontal slide plate 403. The material feeding mechanism 5 is located below each cutting mechanism 4. The material feeding mechanism 5 includes an inclined guide plate 501, two side baffles 502 and a bottom storage box 503.

[0031] The operation process of this embodiment is as follows: When the control system confirms that the steel bar has been delivered to the predetermined cutting position, the three spaced cutting mechanisms 4 are started sequentially according to the preset program. The cutting mechanism 4 closest to the steel bar feeding mechanism 2 is started first. The piston rod of the hydraulic cylinder 409 at this location extends and pushes the horizontal slide plate 403 to move horizontally along the T-slot 402 on the shear support plate 401. The movement of the horizontal slide plate 403 is transmitted to the shear hinge support on the two shear arms 405 through the four inclined tie rods 404 hinged on it. The shear rotation shaft rotatably connected to the shear hinge support rotates accordingly and drives the vertical slider 408 on it to slide in the vertical slot 407, so that the two shear arms 405 move closer to each other. The shear clamps 406 arranged at their front ends complete a closed shearing action to cut off the near end of the steel bar. Then the middle and farthest cutting mechanisms 4 are started synchronously. The two hydraulic cylinders 409 are activated at the same time, pushing their respective horizontal slide plates 403 to move, so that the two ends of the middle section of the steel bar are clamped at the same time. The system cuts the steel bars into multiple fixed-length sections during a single feeding process. After all cutting actions are completed, the electric telescopic rod 308 retracts, pulling the guide plate 301 downwards with its first through shaft 303 as the rotation center. At this time, the two ends of the second through shaft 304 slide in the arc groove of the fixed plate 101 and the steel bar feeding assembly mounting frame. After the guide plate 301 tilts, the cut steel bar sections slide down the inclined plane under the action of gravity and fall onto the inclined guide plate 501 of the material feeding mechanism 5 directly below. The baffles 502 on both sides of the inclined guide plate 501 prevent the steel bar sections from scattering and guide them to the bottom. After collection, the electric telescopic rod 308 extends again, driving the guide plate 301 to smoothly return to the horizontal working position. The winding motor in the rope drive assembly starts to reverse, retracting the wire rope. The traction push plate 307 slides back to the initial position along the first slide column 305 and the second slide column 306. The entire system completes one working cycle and returns to the initial state. Then the above process is repeated.
