Description

Technical Field

[0001] This utility model relates to the field of rebar cutting technology, specifically a rebar cutting workbench. Background Technology

[0002] Reinforcing steel refers to steel bars used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners, and includes plain round bars, ribbed bars, and twisted bars. During the construction of civil engineering foundations and main structures, reinforcing steel bars need to be cut to different lengths for various applications.

[0003] When using a cutting machine to cut steel bars, both ends of the steel bars need to be fixed to prevent displacement. However, during the cutting process, due to the full fixation of the steel bars, the force generated by the cutting machine cannot be buffered, affecting the accuracy of the cutting. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a rebar cutting workbench that solves the problem that, during the rebar cutting process, the rebar cannot be properly buffered from the force generated by the cutting machine due to its full fixation, thus affecting the cutting accuracy. During the rebar cutting process, the rebar is subjected to the force of the cutting machine, and through the action of the buffer and the clamping roller, the rebar can slide appropriately on the clamping roller, thereby avoiding the problems caused by the full fixation of the rebar and improving the cutting accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rebar cutting workbench, comprising a platform assembly, a clamping assembly, a blocking assembly, and a driving assembly. The platform assembly includes a cutting platform, a mounting base, and a hydraulic cylinder. The clamping assembly includes a movable clamping plate. The blocking assembly includes a blocking baffle and a driving plate. The driving assembly includes a driving motor and a threaded rod. A first sliding groove is formed on the inner side of the mounting base. An inner platform groove is formed on the inner side of the cutting platform. Second sliding grooves are symmetrically formed on the walls at both ends of the cutting platform. A cutting machine is mounted on the top of the cutting platform. A buffer is connected to one end of the movable clamping plate. A movable frame is connected to the end of the buffer away from the movable clamping plate. A clamping roller is provided on the inner side of the movable frame. The clamping roller is rotatably connected to the movable frame. A fixed frame is connected to the top of the mounting base. Side plates are symmetrically connected to both ends of the bottom of the blocking baffle. Linkage plates are symmetrically connected to both ends of the driving plate. A limit rod is connected to the inner wall of the inner platform groove.

[0006] The beneficial effects of this utility model are as follows: by setting two sets of clamping components, the two ends of the steel bar to be cut are fixed. During the cutting process, the steel bar is subjected to the force of the cutting machine. Through the action of the buffer and the clamping roller, the steel bar can slide appropriately on the clamping roller, thereby avoiding the problems caused by insufficient fixing of the steel bar and improving the accuracy of cutting.

[0012] The beneficial effects of this improvement are as follows: when the hydraulic cylinder is started, it works and drives the moving clamping plate to move, thereby gradually bringing the moving frame closer to the fixed frame until the clamping rollers on the inner side of the moving frame are in contact with and fixed to the steel bar, thus achieving the clamping of the steel bar.

[0013] In order to limit the movement of the reinforcing bars and thus ensure that the reinforcing bars are positioned in the middle of the clamping rollers:

[0015] The beneficial effects of this improvement are: the outer ring wall of the reinforcing bar is in contact with the clamping roller inside the fixed frame, and the outer ring side of the clamping roller is a concave arc surface, which can play a certain limiting role for the reinforcing bar, thereby allowing the reinforcing bar to be located in the middle of the clamping roller.

[0016] To allow the reinforcing bars to slide properly on the clamping rollers, thereby avoiding problems caused by insufficient fixation of the reinforcing bars:

[0017] As a further improvement to the above technical solution: the lower end of the movable clamping plate is connected to a sliding rod, and the lower end of the sliding rod away from the movable clamping plate is located inside the first sliding groove. There are two sets of clamping components, and the two sets of clamping components are symmetrically installed on both sides of the cutting machine.

[0018] The beneficial effects of this improvement are as follows: by setting up two sets of clamping components to fix both ends of the rebar at the position to be cut, during the cutting process, the rebar is subjected to the force of the cutting machine. Through the action of the buffer and the clamping roller, the rebar can slide appropriately on the clamping roller, thereby avoiding problems caused by insufficient fixation of the rebar and improving the accuracy of cutting.

[0021] The beneficial effects of this improvement are as follows: After adjusting the position of the blocking baffle, place the steel bar to be cut on the mounting base and make one end of the steel bar fit tightly against the blocking pad layer, and then use a cutting machine to cut the steel bar.

[0022] In order to drive the motor to work and drive the screw rod to rotate through the rotating rod, thereby realizing the movement of the drive plate:

[0023] As a further improvement to the above technical solution: the end of the linkage plate away from the drive plate passes through the second slide groove and extends to connect with the side plate; the drive motor is installed on the inner side of the platform inner groove and is electrically connected to the operation panel; the inner wall of the platform inner groove is connected to a partition plate; the limiting rod passes through the partition plate and both ends are connected to the inner wall of the platform inner groove.

The output end of the hydraulic cylinder 15 away from the positioning side plate 14 is connected to the moving clamp 21. The hydraulic cylinder 15 is electrically connected to the operation panel. When the hydraulic cylinder 15 is started, it works and drives the moving clamp 21 to move, thereby causing the moving frame 24 to gradually approach the fixed frame 25 until the clamping roller 26 inside the moving frame 24 is in contact with and fixed to the reinforcing bar. This achieves the clamping of the reinforcing bar. The fixed frame 25 and the movable frame 24 are the same size and symmetrically arranged. The inner side of the fixed frame 25 is rotatably connected to the clamping roller 26. The outer side of the clamping roller 26 is an inwardly concave arc surface.

During the movement, the drive plate 35 drives the side plate 32 to move through the linkage plate 36, thereby realizing the adjustment of the position of the blocking baffle 31.

[0038] The working principle of this utility model is as follows: In use, the position of the blocking baffle 31 is first adjusted according to the predetermined size of the steel bar to be cut. The scale line 12 is used to mark the position of the blocking baffle 31. After starting the drive motor 41, the drive motor 41 operates and drives the threaded rod 44 to rotate via the rotating rod 45. The drive plate 35 moves laterally under the combined action of the limiting rod 43 and the threaded rod 44. During this movement, the drive plate 35 drives the side upright plate 32 to move via the linkage plate 36, thereby achieving… After adjusting the position of the blocking baffle 31, place the steel bar to be cut on the mounting base 13, ensuring one end of the steel bar is tightly fitted against the blocking pad 34. Then, bring the outer wall of the steel bar into contact with the clamping roller 26 inside the fixed frame 25.

Then, the cutting machine 19 is used to cut the steel bar. The mounting base 13 is used to install and fix the clamping assembly 2. The first sliding groove 16 is used as the groove for the sliding rod 22 to slide. The two sets of clamping assemblies 2 are used to fix the two ends of the steel bar to be cut. During the cutting process, the steel bar is subjected to the force of the cutting machine 19. Through the action of the buffer 23 and the clamping roller 26, the steel bar can slide appropriately on the clamping roller 26, thereby avoiding problems caused by insufficient fixation of the steel bar and improving the accuracy of cutting.
