Description

Technical Field

[0001] This utility model relates to the field of steel bar cutting machinery technology, specifically to an integrated machine for automatic straightening and cutting of building steel bars. Background Technology

[0002] Before use, coiled steel bars need to be straightened and then cut to the required length. Currently, steel bar straightening and cutting are usually handled by two separate devices. When the two devices work together, the straightening device needs to be stopped when the cutting device needs to perform the cutting operation. This is cumbersome and affects the efficiency of steel bar cutting. In addition, when the straightening device is stopped, the rotational inertia of the straightening roller and the feeding roller will cause the steel bar to continue to be conveyed forward for a certain distance, which will also cause inaccurate cutting length. Summary of the Invention

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide an integrated machine for automatic straightening and cutting of building steel bars.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An integrated automatic straightening and cutting machine for construction steel bars includes:

[0006] Feeding mechanism;

[0007] A straightening mechanism is provided corresponding to the feeding mechanism, so that the steel bars conveyed by the feeding mechanism pass horizontally through the straightening mechanism and are straightened.

[0008] A cutting mechanism is provided corresponding to the straightening mechanism, and the cutting mechanism includes a base, a horizontally movable knife holder, and a vertically movable knife body. The horizontal moving speed of the knife holder is the same as the horizontal feeding speed of the feeding mechanism, and the knife body is slidably connected to the knife holder.

[0009] Preferably, the feeding mechanism includes an active feeding roller assembly disposed between the straightening mechanism and the cutting mechanism.

[0010] Preferably, the feeding mechanism further includes a driven feeding roller group, and the straightening mechanism is disposed between the active feeding roller group and the driven feeding roller group.

[0011] Preferably, the straightening mechanism includes at least two straightening rollers with limiting rubber sleeves embedded in their surfaces.

[0012] Preferably, at least two of the straightening rollers include upper and lower rollers arranged in an alternating manner.

[0013] Preferably, the cutting mechanism includes a conveyor belt assembly for driving the blade holder to move horizontally.

[0014] Preferably, a linkage drive component is connected between the active feeding roller group and the conveyor belt assembly, and the linkage drive component drives the active feeding roller group to rotate continuously to feed material and the conveyor belt assembly to rotate intermittently to convey material.

[0015] Preferably, the linkage drive assembly includes a complete gear and a partial gear driven coaxially by a motor. One side of the complete gear is engaged with a first driven gear for driving the active feed roller assembly, and one side of the partial gear is engaged with a second driven gear for driving the conveyor belt assembly.

[0016] Preferably, the cutting mechanism further includes a guide rail for driving the blade body to move vertically up and down. The guide rail includes an inclined section and a transition section connected to both ends of the inclined section. The guide rail is disposed between the conveyor belt assembly and the base, and a limiting slide rod that can be slidably inserted into the guide rail is fixed on the side of the blade body.

[0017] Preferably, the top of the blade body is slidably inserted into the blade holder, and a return spring is connected between the blade body and the blade holder.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] (1) This utility model is provided with a straightening mechanism and a cutting mechanism that cooperate with each other, so as to facilitate the straightening and fixed-length cutting of building steel bars in an integrated manner. The cutting mechanism is provided with a horizontally movable blade holder and a vertically lifting blade body, so that the building steel bars can be cut at the same time as straightening and conveying, thereby improving work efficiency.

[0020] (2) The cutting mechanism includes a guide rail that can guide the blade body. The guide rail includes an inclined section and a transition section connected to both ends of the inclined section. A limiting slide rod that can be slidably inserted into the guide rail is provided on the side of the blade body, so as to realize the horizontal movement of the blade holder and the vertical lifting of the blade body at the same time. No additional drive structure is required. The structure is simple, the cost is low, and it can effectively cut the steel bars.

[0021] (3) This utility model is provided with a linkage drive assembly for the linkage drive cutting mechanism and the feeding mechanism. The feeding mechanism achieves continuous rotation drive and the cutting mechanism achieves intermittent transmission drive. This can effectively meet the cyclic transmission of the knife holder and the fixed-length cutting of the steel bar, and ensure that the length of the fixed-length cutting of the steel bar and the length of the cyclic transmission of the knife holder do not affect each other.

[0030] like Figure 1As shown, the automatic straightening and cutting machine for building steel bars provided by this utility model includes a frame, and a feeding mechanism 100, a straightening mechanism 200, a cutting mechanism 300 and a linkage drive assembly 400 installed on the frame.

[0031] Continue to refer to Figure 2 As shown, the feeding mechanism 100 includes a driven feeding roller group 102 and an active feeding roller group 101 (both the driven feeding roller group 102 and the active feeding roller group 101 include two feeding rollers arranged opposite each other). In the figure, the driven feeding roller group 102 is located on the front side of the straightening mechanism 200, and the active feeding roller group 101 is located on the rear side of the straightening mechanism 200. In addition to the position shown in the figure, the active feeding roller group 101 can also be located on the front side of the straightening mechanism 200, with the driven feeding roller group 102 correspondingly adjusted to the rear side of the straightening mechanism 200. The overall goal is to ensure that the straightening mechanism 200 is positioned between the active feeding roller group 101 and the driven feeding roller group 102, thereby ensuring that the reinforcing bars conveyed by the feeding mechanism 100 can pass through the straightening mechanism 200 in a stable horizontal state.

[0032] Continue to refer to Figure 2 As shown, the straightening mechanism 200 has at least two straightening rollers 202 (five in the figure) with limiting sleeves 201 embedded in their surfaces. Specifically, the at least two straightening rollers 202 include staggered upper rollers 203 (three in the figure) and lower rollers 204 (two in the figure). When the reinforcing bar passes through the straightening mechanism 200, the reinforcing bar is confined between the upper rollers 203 and the lower rollers 204 (the surface of the reinforcing bar is in contact with the surface of the limiting sleeves 201 to prevent the reinforcing bar from shifting), and the reinforcing bar is straightened under the relative squeezing action of the upper rollers 203 and the lower rollers 204.

[0033] Continue to refer to Figures 3-6 As shown, the cutting mechanism 300 includes a base, a conveyor belt assembly 303, a guide rail 304, a blade holder 301, and a blade body 302. The conveyor belt assembly 303 includes two conveyor rollers and a conveyor belt sleeved on the rollers. One end of the blade holder 301 is fixed to the conveyor belt, and one end of the blade body 302 slides into the blade holder 301. A return spring 306 connects the blade body 302 and the blade holder 301. The guide rail 304 includes an inclined section and transition sections connecting the two ends of the inclined section. The guide rail 304 is disposed between the conveyor belt assembly 303 and the base, and a limiting slide rod 305, capable of sliding into the guide rail 304, is fixed to the side of the blade body 302. Based on this, and in conjunction with... Figure 3 and Figure 4As shown in the diagram, when the cutter holder 301 is conveyed to the bottom of the conveyor belt assembly 303, the cutter holder 301 moves from left to right. During this movement, the limiting slide bar 305 on the side of the cutter body 302 gradually slides into the left transition section of the guide rail 304. As the movement continues, the limiting slide bar 305 slides into the inclined section of the guide rail 304, thereby vertically pulling the cutter body 302 downward, achieving vertical downward movement of the cutter body 302, stretching the return spring 306, and simultaneously causing the cutting edge at the bottom of the cutter body 302 to gradually approach the straightened steel bar supported on the base. When the limiting slide bar 305 slides into the right transition section of the guide rail 304, the cutter body 302 descends to its lowest point and completes the steel bar cutting. During the cutting process described above, the blade 302 and blade holder 301 move to the right at the same speed as the reinforcing bar. This keeps the blade 302 and the reinforcing bar relatively stationary in the horizontal direction. In other words, the blade 302 only moves vertically downwards relative to the reinforcing bar, ensuring precise cutting dimensions and eliminating the need to stop the feeding mechanism 100. Furthermore, when the limit slide bar 305 moves to the right and slides out of the guide rail 304, the return spring 306 allows the blade 302 to move upwards and reset, ensuring that the blade 302 can repeatedly perform vertical lifting and lowering cuts.

[0034] Continue to refer to Figure 7 As shown, the linkage drive assembly 400 includes a complete gear 401 and an incomplete gear 402 driven by a motor coaxially. One side of the complete gear 401 is meshed with a first driven gear 403 for driving the active feed roller assembly 101, and one side of the incomplete gear 402 is meshed with a second driven gear 404 for driving the conveyor belt assembly 303.

[0035] In summary, the principle of this utility model for integrated automatic straightening and cutting of building steel bars is as follows:

[0036] The complete gear 401 and the incomplete gear 402 are driven to rotate by a motor, wherein:

[0037] The drive gear 401 drives the first driven gear 403 to rotate. The first driven gear 403 is coaxially fixed with one of the feed rollers in the active feed roller group 101, thereby driving the active feed roller group 101 to rotate continuously. The steel bar passes through the driven feed roller group 102, the straightening mechanism 200 and the active feed roller group 101 in sequence, thereby realizing the continuous movement and feeding of the steel bar.

[0038] When the incomplete gear 402 meshes with the second driven gear 404, the incomplete gear 402 drives the second driven gear 404 to rotate. The second driven gear 404 is coaxially fixed with a conveyor roller in the conveyor belt assembly 303, thereby driving the conveyor belt assembly 303 to convey and drive the tool holder 301 to move horizontally. At the same time, with the cooperation of the guide rail 304 and the limiting slide bar 305, the tool body 302 is lifted and cut.

[0039] When the incomplete gear 402 disengages from the second driven gear 404, the cutting mechanism 300 is positioned in its initial state (e.g., Figure 3 (as shown), until the incomplete gear 402 re-engages with the second driven gear 404 to perform the cutting again.

[0040] Specifically, in this invention, the number of teeth on the incomplete gear 402 should ensure that the conveyor belt assembly 303 can complete one full rotation (i.e., the cutter body 302 returns to its initial position after completing one cut) through the meshing transmission between the incomplete gear 402 and the second driven gear 404. Under this constraint, the active feeding roller group 101 can rotate N times and the conveyor belt assembly 303 can transport one rotation, thereby effectively achieving fixed-length cutting of the reinforcing bar, while ensuring that the length of the fixed-length cutting of the reinforcing bar and the length of the cyclic transmission of the cutter head do not affect each other. In addition, by changing the meshing transmission ratio between the complete gear 401 and the first driven gear 403, and between the incomplete gear 402 and the second driven gear 404, the cutting length of the reinforcing bar can be flexibly adjusted.
