Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and in particular to a steel bar shearing device. Background Technology

[0002] As an indispensable material in building structures, steel reinforcement must strictly conform to design blueprints and construction specifications in terms of length and shape. Therefore, during actual construction, steel reinforcement needs to be cut to the required length to ensure it matches the design requirements and meets the structural strength and stability requirements. On construction sites, shearing machines are commonly used to cut steel reinforcement. However, due to the varying sizes and specifications of steel reinforcement, for ease of operation, the reinforcement is usually placed directly into the shearing machine, and workers manually adjust the length to be cut and manually limit the reinforcement. While convenient, this method is prone to deviations in the cut dimensions, failing to meet construction specifications, and increasing the risk of worker injury during the cutting process. Furthermore, only one reinforcement can be cut at a time, which is detrimental to accelerating the construction process. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a rebar shearing device that can simultaneously shear multiple rebars and automatically limit their movement, thereby improving efficiency and protecting the worker's body, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A rebar shearing device includes: a base, a limiting component, and a shearing component.

[0006] The base has recesses at both ends along its length, and multiple V-shaped grooves between the recesses are provided on the top surface of the base along its width. The limiting assembly includes a support rod and a baffle, which are respectively installed in the two recesses and move along their length. The length of the support rod is parallel to the width of the base, and multiple V-shaped slots are provided on its top surface along its length for supporting the reinforcing bars. The baffle is used to abut against one end of the reinforcing bar. The shearing assembly is located above the base and includes a lifting plate that moves vertically. A shearing block is provided below the lifting plate. In application, the shearing block cooperates with the side wall of the recess to shear the reinforcing bar. A pressure block that moves vertically on one side of the shearing block is used to press the reinforcing bar.

[0007] Furthermore, the top surface of the base is provided with multiple partitions along its width direction, the length direction of the partitions is parallel to the length direction of the base, and V-shaped grooves are located between two adjacent partitions. The partitions are installed on the connecting frame, and the connecting frame is installed on the base.

[0008] Furthermore, the two ends of the support rod are sleeved on the slide rod, and the slide rod is installed at the bottom of the base.

[0009] Furthermore, the lifting plate is connected to the moving end of the vertical lifting mechanism and is sleeved on the guide rod. Both the vertical lifting mechanism and the guide rod are installed on the base.

[0010] Furthermore, the bottom surface of the pressure block is provided with a V-shaped positioning groove for limiting the position of the reinforcing bar, and the top surface is provided with a protruding rod. The upper end of the protruding rod is installed on the horizontal plate. The top surface of the horizontal plate is provided with multiple connecting rods, which pass through the lifting plate. Springs are sleeved on the connecting rods, and the two ends of the springs abut against the horizontal plate and the lifting plate respectively, and are always in a compressed state. The upper end of the connecting rod is provided with a retaining ring for abutting against the top surface of the lifting plate.

[0011] Furthermore, a connecting block is installed below the lifting plate, and a shearing block is installed on the bottom surface of the connecting block and locked with bolts.

[0012] The advantages of this invention are as follows: by setting multiple V-shaped grooves and partitions on the base, multiple steel bars can be placed on the base at the same time, and multiple steel bars can be cut at the same time by the shearing block, which greatly improves the shearing efficiency; by applying a limit to the steel bars by the pressure block and the baffle, the steel bars are prevented from shifting during the shearing process, and the baffle can be moved to adapt to different shearing lengths, so as to ensure the shearing accuracy and avoid worker injury; the support rod that supports the steel bars can be moved, so that the steel bars can be directly dropped after shearing, which can further improve the shearing efficiency.

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-4As shown, this example provides a rebar shearing device, including: a base 100, a limiting component 200, and a shearing component 300.

[0020] The base 100 has recesses 101 at both ends along its length. The top surface of the base 100 has multiple V-shaped grooves 102 located between the recesses 101 along its width direction for supporting reinforcing bars. The limiting assembly 200 includes a support rod 201 and a baffle 203, each installed in one of the two recesses 101 and moving along its length. The support rod 201 is parallel to the width direction of the base 100 along its length, and its top surface has multiple V-shaped slots 202 along its length for supporting reinforcing bars. The baffle 203 abuts against one end of the reinforcing bar. The shearing assembly 300 is located above the base 100 and includes a lifting plate 301 that moves vertically. A shearing block 302 is located below the lifting plate 301. When the reinforcing bar needs to be sheared, the shearing block 302 engages with the sidewall of the recess 101 to cut the reinforcing bar. A pressure block 303 that moves vertically on one side of the shearing block 302 is used to press the reinforcing bar.

[0021] Specifically, the top surface of the base 100 is provided with a plurality of partitions 103 along its width direction. The length direction of the partitions 103 is parallel to the length direction of the base 100. V-shaped grooves 102 are respectively located between two adjacent partitions 103. The partitions 103 are installed on the connecting frame 104, and the connecting frame 104 is installed on the base 100. When the reinforcing bar is placed on the base 100, the reinforcing bar will be located in the V-shaped groove 102, and the two adjacent reinforcing bars will be separated from each other by the partitions 103, so that the reinforcing bar can be more easily limited.

[0022] Specifically, the two ends of the support rod 201 are sleeved on the slide rod 204, which is installed at the bottom of the base 100. After the steel bar is cut, the steel bar can be pulled out a certain distance. Then, the support rod 201 is pushed toward the V-shaped groove 102 on the base 100, and the steel bar will fall under its own weight. This eliminates the need to manually remove the steel bars from the base 100 one by one, which can greatly save the time of transferring the steel bars and improve the cutting efficiency. A transfer cart can be set under the base 100 so that the steel bars can be transferred in time after the transfer cart collects a certain amount of steel bars.

[0023] Specifically, the lifting plate 301 is connected to the moving end of the vertical lifting mechanism and is sleeved on the guide rod 304. Both the vertical lifting mechanism and the guide rod 304 are installed on the base 100. The guide rod 304 provides a limiting function for the movement of the lifting plate 301, making the movement of the lifting plate 301 more stable. When it is necessary to drive the lifting plate 301 to move up and down, the vertical lifting mechanism can be activated. The vertical lifting mechanism can be a hydraulic cylinder.

[0024] Specifically, the bottom surface of the pressure block 303 is provided with a V-shaped positioning groove 305 for limiting the position of the reinforcing bar, and the top surface is provided with a protruding rod 306. The upper end of the protruding rod 306 is installed on the horizontal plate 307. The top surface of the horizontal plate 307 is provided with multiple connecting rods 308, which pass through the lifting plate 301. A spring 309 is sleeved on the connecting rod 308. The two ends of the spring 309 abut against the horizontal plate 307 and the lifting plate 301 respectively, and are always in a compressed state. The upper end of the connecting rod 308 is provided with a retaining ring 310 for abutting. When the lifting plate 301 reaches the top surface and the reinforcing bar needs to be cut, the vertical lifting mechanism drives the lifting plate 301 to move downward. The pressure block 303 will first contact the reinforcing bar. As the lifting plate 301 continues to move downward, the pressure block 303 will move relative to the lifting plate 301, and the spring 309 will be further compressed. During this process, the shearing block 302 will contact the reinforcing bar and cut it. Then, the lifting plate 301 can be raised again by the vertical lifting mechanism.

[0025] Specifically, a connecting block 311 is installed below the lifting plate 301, and a shearing block 302 is installed on the bottom surface of the connecting block 311 and locked with bolts, so as to facilitate the replacement of the worn shearing block 302.

[0026] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
