Description

Technical Field

[0001] This application relates to the field of rebar cutting equipment technology, specifically to a rebar cutting device. Background Technology

[0002] Reinforcing steel bars are an essential material widely used in construction engineering, playing a crucial role in bearing tensile forces within concrete structures. During construction, these bars need to be cut, bent, and processed to meet engineering design requirements. Common types of reinforcing steel bar cutting machines include horizontal and vertical models. Horizontal cutting machines are primarily used for cutting reinforcing steel bars to length in construction projects. They are operated by placing the reinforcing steel bars horizontally on a feeding rack and cutting them using a hydraulically or electrically driven blade.

[0003] Traditional cutting methods require measuring and marking the rebar to obtain different lengths, which is cumbersome. To improve cutting efficiency, existing technology uses a sliding spacing structure on the feeding rack to limit the cutting length. The cutter head is controlled to cut when the rebar extends to the spacing structure. However, in practical use, the cutting length is limited by the length of the feeding rack. Cutting longer rebars requires enlarging the feeding rack, increasing equipment size and cost, and making movement and operation in confined spaces difficult. Existing sliding spacing structures often have low positioning accuracy and are prone to deviations during sliding, leading to inaccurate cutting lengths. Furthermore, frequent sliding and fixing operations can cause wear and loosening of the spacing structure, further affecting cutting accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar cutting device that does not rely on the length of the feeding rack, thereby achieving precise cutting of rebars of any length, improving cutting efficiency, reducing the space occupied by the rebar cutting device, and facilitating movement and operation.

[0005] This application is achieved through the following technical solution, specifically:

[0006] A rebar cutting device includes a rebar cutting mechanism, a distance measuring module mounted on the rebar cutting mechanism, and a material feeding mechanism disposed on the rebar output side of the rebar cutting mechanism; the rebar cutting mechanism includes a material loading groove that allows the rebar to pass through and a cutting head disposed on the side of the material loading groove; the distance measuring module includes a frame-shaped bracket fixedly connected to both sides of the material loading groove, a photoelectric sensor mounted on the lower end face of the frame-shaped bracket, and a PLC electrically connected to the photoelectric sensor.

[0007] In this solution, by introducing a distance measuring module into the rebar cutting mechanism, the cutting length of the rebar can be determined based on the distance the rebar extends from the cutting head, without relying on the length of the feeding rack. This enables precise cutting of rebars of any length, improves cutting efficiency, reduces the space occupied by the rebar cutting device, and facilitates movement and operation.

[0008] As an improvement to the material feeding mechanism in this application, the material feeding mechanism includes a guide frame that is inclined downward and a sliding gripping part installed on the upper part of the guide frame, wherein the sliding gripping part is arranged parallel to the direction of the steel bar passing through.

[0009] Furthermore, the sliding gripping part includes a slide groove and at least one clamp mounted on the slide groove.

[0010] Furthermore, the inner clamping surface of the clamp is provided with an anti-slip texture.

[0011] As an improvement to the guide frame in this application, the guide frame is a rectangular frame with baffles at both the upper and lower ends, and the bottom is composed of several longitudinally arranged strip plates; the strip plates are movably connected to the upper and lower ends of the rectangular frame.

[0012] Furthermore, a material collection trough is provided at the bottom of the guide frame near the rebar cutting mechanism.

[0013] As an improvement to the rebar cutting mechanism in this application, a first limiting ring and a second limiting ring are respectively provided on both sides of the cutting head, and an opening is provided at the lower part of the first limiting ring located on the rebar exit side.

[0014] As an improvement to the present application, a base is also provided at the lower part of the rebar cutting mechanism.

[0015] The beneficial effects of this application are as follows:

[0016] The solution proposed in this application introduces a distance measuring module into the rebar cutting mechanism, which can determine the cutting length of the rebar based on the distance the rebar extends from the cutting head, without relying on the length of the feeding rack. This enables precise cutting of rebars of any length, improves cutting efficiency, reduces the space occupied by the rebar cutting device, and facilitates movement and operation.

Detailed Implementation

[0022] The following will be combined with the appendix Figures 1-2 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] In view of the problems existing in the background technology or products, Figure 1 and Figure 2 The following are schematic diagrams of the structure of a rebar cutting device according to an embodiment of this application from two different perspectives, as shown below. Figure 1 and 2 As shown, this application provides a rebar cutting device, including: a rebar cutting mechanism 1, a distance measuring module 2 installed on the rebar cutting mechanism 1, and a material feeding mechanism 3 disposed on the rebar output side of the rebar cutting mechanism 1; the rebar cutting mechanism 1 includes a material loading groove that allows the rebar to pass through and a cutting head disposed on the side of the material loading groove, the distance measuring module 2 includes a frame-shaped bracket 21 fixedly connected to both sides of the material loading groove, a photoelectric sensor 22 installed on the lower end face of the frame-shaped bracket 21, and a PLC electrically connected to the photoelectric sensor 22.

[0024] Specifically, the rebar cutting mechanism 1 includes a material loading groove and a cutting head (not shown in the figure). The material loading groove guides rebars of different diameters smoothly through the cutting head, ensuring that the rebars remain straight during the cutting process. The cutting head is used to cut the rebars and can take various forms, such as a disc-type cutting head or a scissor-type cutting head. The distance measuring module 2 is used to measure the distance the rebar extends from the cutting head. The distance measuring module 2 includes a frame bracket 21, a photoelectric sensor 22, and a programmable logic controller (PLC). The frame bracket 21 is fixedly connected to both sides of the material loading groove to support the photoelectric sensor 22. The photoelectric sensor 22 is mounted on the lower end face of the frame bracket 21, perpendicular to the direction of rebar movement, and is used to measure the distance the rebar extends from the cutting head. The transmitting and receiving ends of the photoelectric sensor 22 are located on both sides of the material loading trough. When the rebar enters the trough and blocks the emitted beam of the photoelectric sensor 22, the light signal received by the receiving end changes. The photoelectric sensor 22 transmits this change signal to the PLC. The PLC calculates the length of the rebar based on the signal change of the photoelectric sensor 22 and the preset rebar moving speed, and then controls the cutting head to cut the rebar, thereby achieving precise cutting of rebars of any length. The unloading mechanism 3 is located on the rebar exit side of the rebar cutting mechanism 1 to ensure that the cut rebar can slide smoothly and avoid the rebar from scattering or piling up. It should be noted that the rebar enters the rebar cutting mechanism 1 at a constant speed.

[0025] Continue reading Figure 1 and 2 In one implementation, the feeding mechanism 3 includes a guide frame 31 that is inclined downward and a sliding gripping part 32 installed on the upper part of the guide frame 31. The sliding gripping part 32 is arranged parallel to the direction of the reinforcing bar insertion.

[0026] Specifically, the main function of the guide frame 31 is to guide the cut steel bars to slide smoothly into the collection area. Its tilt angle can be adjusted according to actual needs to ensure that the steel bars slide smoothly under gravity. In one implementation, the guide frame 31 is a rectangular frame with baffles 311 at both the upper and lower ends, and the bottom is composed of several longitudinally arranged strip plates 312; the strip plates 312 are movably connected to the upper and lower ends of the rectangular frame.

[0027] A baffle plate 311 is used to prevent reinforcing bars from falling off the guide frame 31. Strip plates 312 are used to support the sliding of different reinforcing bars. The strip plates 312 are movably connected to the upper and lower ends of the rectangular frame. By adjusting the spacing between the strip plates 312, reinforcing bars of different specifications can be supported and collected. For example, the strip plates 312 are bolted to the guide frame 31. On the side of the guide frame 31 near the reinforcing bar cutting mechanism 1, the spacing between the strip plates 312 is set wider, allowing shorter reinforcing bars obtained after cutting to fall directly through the gaps between the strip plates 312. Preferably, a collection trough 33 is provided at the bottom of the guide frame 31 near the reinforcing bar cutting mechanism 1. Shorter reinforcing bars are collected through the collection trough 33. This allows for the collection and sorting of reinforcing bars of different lengths without manual sorting.

[0028] The main function of the sliding gripping part 32 is to fix and hold the steel bar before cutting, preventing it from rebounding or slipping due to cutting force when cutting long steel bars, thus ensuring operational safety. In one implementation, the sliding gripping part 32 includes a groove 321 and at least one clamp 322 mounted on the groove 321.

[0029] The chute 321 provides guidance for the movement of the sliding gripping part 32, ensuring that it can move smoothly along the direction of the rebar insertion. The clamp is used to hold the rebar and prevent it from sliding or deviating during the cutting process. The movement of the sliding gripping part 32 can be driven by a cylinder, motor or hydraulic device. By controlling the action of the drive device, precise control of the sliding gripping part 32 can be achieved. Before cutting, the sliding gripping part 32 clamps the rebar to ensure that the rebar remains stable during the cutting process. After cutting, the sliding gripping part 32 releases the rebar, allowing the rebar to slide down along the guide frame 31 under the action of gravity. The clamping force of the sliding gripping part 32 can be adjusted according to the diameter and material of the rebar to ensure the reliability of the clamping.

[0030] Optionally, to improve the automation of material feeding, the sliding handle 32 can be electrically connected to the PLC to realize automatic monitoring and control of the material feeding process. For example, when the length of the steel bar is found to be up to standard, the clamping and releasing actions of the sliding handle 32 can be controlled according to the signal sent by the PLC to realize automatic material feeding.

[0031] Preferably, the inner clamping surface of the clamp 322 is provided with an anti-slip texture 323.

[0032] Continue reading Figure 1 and 2 In one implementation, a first limiting ring 11 and a second limiting ring 12 are respectively provided on both sides of the cutting head, and the first limiting ring 11 located on the side where the reinforcing bar is exposed has an opening at its lower part.

[0033] Specifically, the function of the first limiting ring 11 and the second limiting ring 12 is to restrict the lateral movement of the reinforcing bar during the cutting process, preventing the reinforcing bar from rebounding or deviating under the cutting force, thereby ensuring the accuracy and safety of the cutting. The inner diameter of the first limiting ring 11 and the second limiting ring 12 should be slightly larger than the diameter of the reinforcing bar to ensure that the reinforcing bar can pass smoothly while effectively restricting its lateral movement. The first limiting ring 11 is located on the side where the reinforcing bar exits, and its lower part has an opening. This opening is designed to allow the cut reinforcing bar to naturally roll through the opening to the guide frame, avoiding the reinforcing bar being blocked by the limiting ring after cutting, causing jamming or accumulation.

[0034] Continue reading Figure 1 and 2 In one implementation, a base 4 is also provided at the lower part of the rebar cutting mechanism 1.

[0035] Specifically, the base 4 supports the rebar cutting mechanism 1 and can be connected to the ground via a fixing device to improve the stability of the rebar cutting mechanism 1. The base 4 effectively prevents the rebar cutting mechanism 1 from tilting or moving during operation, thereby improving cutting accuracy and safety. Optionally, rollers and a locking device are also provided under the base 4 for position adjustment or movement.
