Description

Technical Field

[0001] This utility model belongs to the field of engineering equipment technology, and specifically relates to a quantitative cutting device for steel bars. Background Technology

[0002] During construction, steel bars need to be cut and trimmed according to the design blueprints. If the length of the steel bars exceeds the actual requirements, they need to be cut to ensure that their length meets the project requirements and standards. This not only avoids wasting materials but also ensures construction quality and safety.

[0003] In existing technologies, the cutting of reinforcing bars using rebar cutting devices mostly relies on the experience of technicians, or involves measuring the rebar with a ruler and marking the cutting positions before cutting. However, cutting based on experience has low accuracy, while using a ruler for measurement has a limited scope. Therefore, how to quickly and conveniently perform quantitative cutting of reinforcing bars is a problem that needs to be solved in this field. Utility Model Content

[0004] To address the problem of how to quickly and conveniently complete the quantitative cutting of reinforcing bars in existing technologies, this utility model provides a quantitative cutting device for reinforcing bars.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A rebar quantitative cutting device includes a base, a cutting platform on the base, a cutting groove on the cutting platform, a cutting mechanism at the cutting groove, a main conveying mechanism and a length measuring mechanism on both sides of the cutting groove along its length extension direction, the main conveying mechanism including a conveying component and a fixing component, the length measuring mechanism including a fixing part connected to the cutting platform, a retractable measuring part on the fixing part, and a fixing groove for cooperating with the rebar at the end of the measuring part away from the fixing part.

[0007] By adopting this technical solution, the present invention sets a main conveying mechanism and a length measuring mechanism on both sides of the cutting groove. The main conveying mechanism conveys the steel bar forward, and one end of the steel bar is located in the fixed groove of the length measuring mechanism. When the steel bar moves forward, it drives the retractable measuring part to extend and retract. As the measuring part extends, the exposed scale gradually increases. When the required scale is observed, the conveying stops. At this time, the part to be cut is aligned with the cutting mechanism, and the cutting mechanism is started to cut the steel bar. This can realize the rapid and convenient quantitative cutting of steel bars, effectively improve work efficiency, and save manpower.

[0008] Preferably, the fixing part includes a left fixing member and a right fixing member arranged symmetrically, and the measuring part includes a left measuring member and a right measuring member. The left measuring member is disposed on the left fixing member to form a left connecting frame, and the right measuring member is disposed on the right fixing member to form a right connecting frame. The gap between the left connecting frame and the right connecting frame forms a measuring groove for accommodating the reinforcing bar, and the measuring groove is connected to the fixing groove.

[0009] After adopting this technical solution, the length measuring mechanism is set as a through structure. After the steel bar is cut, since one end is no longer supported, it can fall from the measuring groove to the bottom without manual removal, which is convenient for operation.

[0010] Preferably, an auxiliary conveying mechanism is provided inside the measuring tank.

[0011] By adopting this technical solution, the conveying force can be increased through the auxiliary conveying mechanism, ensuring the smooth delivery of steel bars.

[0012] Preferably, the bottom of the cutting groove is inclined, and the height of the end near the main conveying mechanism is greater than the height of the end near the length measuring mechanism.

[0013] After adopting this technical solution, the end of the steel bar near the cutting mechanism will fall into the cutting groove after the steel bar is cut. In order to avoid affecting subsequent cutting, the steel bar can be smoothly dropped to the ground by setting an inclined structure.

[0014] Preferably, the fixing part is provided with a mounting groove, and the measuring part is slidably disposed in the mounting groove. The measuring part includes several sliding shells sequentially sleeved from the inside to the outside. Two adjacent sliding shells can slide relative to each other. The outermost sliding shell is slidably connected to the mounting groove. The fixing groove is provided at one end of the innermost sliding shell outside the mounting groove. The innermost sliding shell is connected to the bottom of the mounting groove by an elastic element. Each sliding shell has a scale on its top, and the scale on each sliding shell forms a continuous scale from the innermost sliding shell to the outermost sliding shell.

[0015] With this technical solution, one end of the steel bar abuts against the fixed groove. As the main conveying mechanism conveys the steel bar, the innermost sliding shell moves outward. Since the sliding shells overlap, when the innermost sliding shell slides to its limit position, it can drive the adjacent sliding shell to slide out, thereby gradually revealing the scale on the sliding shell. The length of the steel bar located between the fixed groove and the cutting structure can be clearly known through the scale, thus achieving quantitative cutting.

[0016] Preferably, the main conveying mechanism includes a support frame with a through groove, and the conveying component and the fixing component are disposed in the through groove.

[0017] Preferably, the conveying assembly includes a first conveying member and a second conveying member with identical structures and symmetrical arrangement. The first conveying member includes a bracket, on which a conveying roller is rotatably connected. The bracket is provided with a driving member for driving the conveying roller to rotate. The gap between the conveying roller of the first conveying member and the conveying roller of the second conveying member forms a conveying groove for accommodating the reinforcing bar.

[0018] With this technical solution, the steel bars are clamped by the first and second conveying components that are symmetrically arranged, and the steel bars are moved forward by the rotation of the two conveying rollers.

[0019] Preferably, the bracket and the support frame are connected by a first electric telescopic rod.

[0020] After adopting this technical solution, the distance between the bracket and the support frame can be adjusted by the first electric telescopic rod, thereby adjusting the width of the conveying trough to realize the conveying of steel bars of different diameters.

[0021] Preferably, the fixing assembly includes a second electrically operated telescopic rod connected to the bracket, wherein the telescopic end of the second electrically operated telescopic rod is provided with an abutment for rebar engagement.

[0022] After adopting this technical solution, in order to prevent the steel bars from moving during the cutting process after the conveying is completed, they can be fixed in the conveying trough by fasteners, thereby fixing the steel bars and facilitating the smooth cutting of the steel bars.

[0023] Preferably, the base is provided with wheels at its bottom.

[0024] With this technical solution, the quantitative cutting device can be moved by the walking wheels.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0026] This invention features a main conveying mechanism and a length measuring mechanism on both sides of the cutting groove. The main conveying mechanism transports the reinforcing bar forward, with one end of the bar positioned in the fixed groove of the length measuring mechanism. As the reinforcing bar moves forward, it causes the retractable measuring part to extend and retract. As the measuring part extends, the exposed scale gradually increases. When the desired scale is reached, the conveying stops, and the part to be cut is aligned with the cutting mechanism. The cutting mechanism is then activated to cut the reinforcing bar, enabling rapid and convenient quantitative cutting of the reinforcing bar, effectively improving work efficiency and saving manpower.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] The following is combined Figures 1-7 This utility model will be described in detail.

[0039] like Figure 1 As shown, a rebar quantitative cutting device includes a base, on which a cutting platform 6 is provided. A cutting groove 4 is provided on the cutting platform 6, and a cutting mechanism 5 is provided at the cutting groove 4. It should be noted that the structure and working principle of the cutting mechanism 5 in this embodiment are the same as those in the prior art. For example, the structure and working principle of the cutting mechanism 5 of the GQ50 rebar cutter can be referred to. Since the cutting mechanism 5 is not the inventive point of this utility model, its structure and working principle will not be described in detail here. A main conveying mechanism and a long... The length measuring mechanism (i.e., respectively set at the front and rear ends of the cutting groove 4) includes a main conveying mechanism comprising a conveying component 12 and a fixing component 13. The length measuring mechanism includes a fixing part 7 connected to the cutting base 6. The fixing part 7 is equipped with a retractable measuring part. At the end of the measuring part furthest from the fixing part 7, a fixing groove 9 is provided to cooperate with the reinforcing bar. The fixing groove 9 is cylindrical in shape, its size is larger than the largest diameter reinforcing bar 17, and its depth is approximately 2-3 mm. Its function is to limit and support one end of the reinforcing bar 17, facilitating the extension of the measuring part and also facilitating smooth cutting. Its usage can be referred to... Figure 6When in use, one end of the reinforcing bar 17 is first inserted into the main conveying mechanism, which then conveys the reinforcing bar 17 forward. When the end of the reinforcing bar 17 reaches the fixed groove 9, it represents the minimum length to be cut. This minimum length is the initial distance between the cutting mechanism 5 and the fixed groove 9. This distance can be set according to actual needs to meet the requirements of quantitative cutting. If the length to be cut is the minimum cutting length, the conveying component 12 can be turned off and the conveying can be stopped once the end of the reinforcing bar 17 is observed to have entered the fixed groove 9. Then, the fixing component 13 can be started to fix the reinforcing bar 17. After fixing, the cutting mechanism 5 can be started to cut the reinforcing bar 17. If the length to be cut is greater than the minimum cutting length, the reinforcing bar 17 can be conveyed forward through the conveying component 12 after it is inserted into the fixed groove 9 until the required length is observed through the measuring unit. Then, the conveying can be stopped, the fixing component 13 can be started to fix the reinforcing bar 17, and the cutting mechanism 5 can be started to cut the reinforcing bar 17.

[0040] In this embodiment, the opening and closing of the conveying component 12, the fixing component 13, and the cutting mechanism 5 are all performed manually. However, in other embodiments, to save labor, a corresponding control system can be used, including a controller electrically connected to the cutting mechanism 5, the conveying component 12, and the fixing component 13. The controller is electrically connected to a timer and a control display screen. The operator can input the required cutting length on the control display screen. In this embodiment, an infrared rangefinder is installed on the movement path of the steel bar 17 in the cutting groove 4. The infrared rangefinder is electrically connected to the controller. When the infrared rangefinder detects a change in distance, the timer starts timing. Since the conveying speed of the conveying component 12 is constant, and the distance between the infrared rangefinder and the cutting mechanism 5 is constant, the movement distance of the steel bar 17 can be calculated based on the time and speed, and the moving length of the steel bar 17 can be determined. When the required cutting length is reached, the controller automatically closes the conveying component 12 and starts the fixing component 13 to fix the steel bar 17. After fixing, the cutting mechanism 5 is automatically started to cut the steel bar 17, which improves the convenience of steel bar cutting.

[0041] In one embodiment, such as Figure 7 The fixing part 7 shown includes a left fixing member and a right fixing member arranged symmetrically. The measuring part includes a left measuring member and a right measuring member. The left measuring member is set on the left fixing member to form a left connecting frame, and the right measuring member is set on the right fixing member to form a right connecting frame. The gap between the left connecting frame and the right connecting frame forms a measuring groove for accommodating the reinforcing bar. The measuring groove is connected to the fixing groove 9. The width of the measuring groove is greater than the diameter of the maximum diameter reinforcing bar 17 that needs to be cut. In use, the reinforcing bar 17 extends out from the cutting groove 4 and enters the measuring groove, and then enters the fixing groove 9 through the measuring groove.

[0042] In one embodiment, such as Figure 5 and Figure 7 As shown, the fixing part 7 is provided with a mounting groove 14, and the measuring part is slidably disposed in the mounting groove 14. The measuring part includes a plurality of sliding housings 8 sequentially sleeved from the inside to the outside (the structure of which is shown in the figure). Figure 5 As shown), two adjacent sliding housings 8 can slide relative to each other (smooth sliding and anti-detachment achieved through the cooperation of multiple sliding grooves and sliders). The outermost sliding housing 8 is slidably connected to the mounting groove 14 (smooth sliding and anti-detachment achieved through the cooperation of sliding grooves and sliders). The innermost sliding housing 8 has the fixing groove 9 at one end outside the mounting groove 14 (the innermost sliding housing 8 is a cylindrical structure that is not connected front to back, while the other sliding housings 8 are cylindrical structures that are connected front to back). The innermost sliding housing 8 is connected to the bottom of the mounting groove 14. The sliding housing 8 is connected via an elastic element 15 (in this embodiment, the elastic element is a spring, and the spring force can be set as needed). Each sliding housing 8 has a scale 10 on its top (upward-facing side). The scale 10 on each sliding housing 8 forms a continuous scale 10 from the innermost sliding housing 8 to the outermost sliding housing 8, and the scale 10 on each sliding housing 8 increases sequentially from the innermost sliding housing 8 to the outermost sliding housing 8. The initial scale on the innermost sliding housing 8 represents the distance from the cutting mechanism 5 to the fixing groove 9 in the initial state. As the reinforcing bar 17 extends sequentially along with each sliding housing 8, the scale protruding from the junction of the measuring part and the fixing part gradually increases. This scale at the junction represents the length from the end of the reinforcing bar 17 to the cutting mechanism 5. When the required length is observed, the conveying assembly 12 can be closed and the fixing assembly 13 can be activated.

[0043] In one embodiment, such as Figure 2 As shown, the main conveying mechanism includes a support frame 1, on which a through groove is provided. The conveying assembly 12 and the fixing assembly 13 are disposed within the through groove, as shown. Figure 3 and 4 As shown, the conveying assembly 12 includes a first conveying member 121 and a second conveying member 122 that are identical in structure and symmetrically arranged, such as... Figure 3As shown in this embodiment, the first conveying component 121 and the second conveying component 122 are disposed on the left and right sides of the conveying trough. The first conveying component 121 includes a bracket 1212, which serves to mount the driving component and support the smooth rotation of the conveying roller 1211. The conveying roller 1211 is rotatably connected to the bracket 1212, and a driving component 1213 is disposed on the bracket 1212 to drive the conveying roller 1211 to rotate. The gap between the conveying roller 1211 of the first conveying component 121 and the conveying roller 1211 of the second conveying component 122 forms the conveying trough 2 for accommodating the reinforcing bar 17. To ensure the smooth conveying of the reinforcing bar 17, a rubber sleeve with anti-slip strips is fitted on the surface of the conveying roller 1211 to increase the friction between the conveying roller 1211 and the reinforcing bar 17. The conveying assembly 12, composed of the symmetrically arranged first conveying component 121 and second conveying component 122, can clamp and convey the reinforcing bar 17.

[0044] In one embodiment, the bracket 1212 is connected to the support frame 1 via a first electric telescopic rod 16. Specifically, the support frame has an installation space with a window communicating with the through groove. The end of the conveying roller 1211 extends from the window into the conveying groove 2. The bracket 1212 and the drive component 1213 are located within the installation space, and the bracket 1212 is connected to the inner wall of the installation space via the first electric telescopic rod 16. The distance between the first conveying component 121 and the second conveying component 122, i.e., the width of the conveying groove 2, can be adjusted by extending and retracting the first electric telescopic rod 16 to meet the conveying requirements of steel bars of different diameters. Before initially inserting the steel bar 17 into the conveying groove 2, the distance between the first conveying component 121 and the second conveying component 122 can be increased. After the head of the steel bar 17 passes through the conveying groove 2, the distance between the first conveying component 121 and the second conveying component 122 can be decreased, so that the two conveying rollers 1211 respectively abut against the two sides of the steel bar 17, thereby conveying it. Operators can judge whether the two conveying rollers 1211 are in full contact with the steel bar 17 based on experience and the diameter of the steel bar 17. In other embodiments, in order to more easily know whether the conveying rollers 1211 are in contact with the steel bar 17, a pressure sensor can be installed on the conveying rollers 1211. The pressure sensor can be used to know the magnitude of the contact force between the conveying rollers 1211 and the steel bar, thereby ensuring that the friction between the conveying rollers 1211 and the steel bar 17 is large enough to ensure the smooth conveying of the steel bar 17.

[0045] In one embodiment, the fixing component 13 includes a second electrically operated telescopic rod connected to the support frame 1. The telescopic end of the second electrically operated telescopic rod is provided with an abutment for engaging with the reinforcing bar 17. The telescopic movement of the second electrically operated telescopic rod allows the abutment to engage with the reinforcing bar 17. To increase the abutment force, a rubber sleeve can be fitted onto the abutment to increase friction. In other embodiments, to more clearly determine whether the abutment is engaging with the reinforcing bar 17, a pressure sensor can be installed on the abutment. The pressure sensor can detect the magnitude of the abutment force between the abutment and the reinforcing bar 17, ensuring the effective fixing of the reinforcing bar 17.

[0046] In one embodiment, the bottom of the cutting groove 4 is an inclined structure, and the height of the end near the main conveying mechanism is greater than the height of the end near the length measuring mechanism. After the rebar 17 is cut, the end near the cutting mechanism will fall into the cutting groove 4. To avoid affecting subsequent cutting, the inclined structure ensures that the rebar 17 falls smoothly to the ground.

[0047] In one embodiment, the bottom of the base is provided with a traveling wheel 3, which can move the device to the required position. Of course, in order to ensure that the cutting is carried out smoothly, the traveling wheel should also have a locking function.

[0048] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
