Description

Technical Field

[0001] The invention belongs to the technical field of steel bar cutting, and in particular, relates to a steel bar cutting device and a method for cutting steel bars in construction. Background Art

[0002] In the process of construction, building materials such as steel bars are often needed. However, the delivered steel bars are not cut and do not meet the length requirements of construction. Therefore, they often need to be cut on site during construction. The existing method is to cut the steel bars using a steel bar cutting device.

[0003] However, it is found in actual use that the steel bars generally need to be cut multiple times during the cutting process. Therefore, after each cutting, the operator needs to re-fix the end face of the steel bar, which makes the operation process more complicated. In addition, the surface temperature of the steel bar just cut is high, and it is risky to directly control the clamping structure by hand to clamp. After cutting, the operator generally uses an inclined guide plate for discharge. However, the surface of the steel bar is rough and the friction is large, especially for steel materials such as rebar. Therefore, the steel bar cannot slide down smoothly along the guide plate when discharging, which affects the discharge and causes low cutting efficiency.

[0061] The present invention also discloses a cutting method of a construction steel bar cutting device, the steps of which are as follows:

[0062] Step 1: Loading, the locking sleeve 3 is driven to move by shifting the electric push rod 321, and the locking sleeve 3 drives the steel bar 4 clamped inside to move, and the steel bar 4 is inserted into the guide sleeve 61 and the positioning sleeve 611;

[0063] Step 2: Automatic clamping. As the steel bar 4 moves, the end of the steel bar 4 finally contacts the push plate 64, pushing the push plate 64 to move outward. The push plate 64 slides along the guide plate 63. When the push plate 64 passes over the slope 631, the guide plate 63 tends to move downward under the elastic force of the return spring 624, thereby driving the insertion rod 621 to move downward. The insertion rod 621 moves downward and pushes the pressure plate 622 to slide downward, thereby clamping the steel bar 4 to be cut.

[0064] Step 3: Automatic unlocking. When the guide plate 63 moves downward, the top clamping plate 211 moves downward synchronously, and the clamping plate 211 and the positioning plate 21 on the adjusting electric push rod 22 are separated, thereby unlocking the cutter 2.

[0065] Step 4: Cutting, the cutting depth of the cutter 2 is controlled by adjusting the electric push rod 22, and the electric slider 221 slides on the slide rail 222 to drive the cutter 2 to move horizontally, thereby cutting the steel bar 4;

[0066] Step five: unloading, the unloading electric push rod 71 drives the slide bar 7 to move, the slide bar 7 drives the rocker arm 72 to rotate, the rocker arm 72 drives the flip plate 6 installed with the steel bar 4 to rotate, and the flip plate 6 is tilted at a certain angle to facilitate the sliding of the steel bar 4 to unload, and at this time the push plate 64 slides along the combined slide groove, when the push plate 64 slides in the flip slide groove 732, the relative positions of the push plate 64 and the flip plate 6 do not change, and the steel bar 4 and the workbench 1 are separated at this time, and when the push plate 64 slides on the shift slide groove 733, the push plate 64 slides on the flip plate 6, pushing the steel bar 4 to move outward, thereby achieving the purpose of unloading and ensuring that the steel bar 4 will not be stuck on the flip plate 6, affecting the unloading operation.

[0067] The implementation principle of a construction steel bar cutting device and method of this embodiment is as follows:

[0068] The locking sleeve 3 is driven to move by shifting the electric push rod 321, and the steel bar 4 is inserted into the internal through hole 31 of the locking sleeve 3, and the steel bar 4 is locked as a whole by the locking bolt 311. During the movement of the locking sleeve 3, the steel bar 4 can be driven to move synchronously and the steel bar 4 can be inserted into the guide sleeve 61 and the positioning sleeve 611.

[0069] As the steel bar 4 moves, the end of the steel bar 4 finally contacts the push plate 64, pushing the push plate 64 to move outward, and the push plate 64 can drive the reset slider 65 to slide on the reset slot 651, and when the reset slider 65 slides outward on the guide rod 652, the first spring 653 can be compressed and the second spring 654 can be stretched, and the reset operation is conveniently performed by the first spring 653 and the second spring 654. When the push plate 64 slides outward, the vertical rod 642 and the guide wheel 643 on the push plate 64 slide along the guide plate 63, and when the vertical rod 642 passes over the slope 631, the guide plate 63 has a tendency to move downward under the elastic force of the reset spring 624, thereby driving the insertion rod 621 to move downward, and the insertion rod 621 can drive the baffle 623 to slide on the extrusion cover 62, and the insertion rod 621 moves downward to drive the pressing plate 622 to slide downward, clamping the steel bar 4 to be cut.

[0070] When the guide plate 63 moves downward, the side wall of the guide plate 63 slides downward along the limit rod 632, and the limit plate 633 on the limit rod 632 prevents the guide plate 63 and the limit rod 632 from separating, and when the guide plate 63 moves downward, it drives the connecting rod 212 to slide downward synchronously, and the connecting rod 212 drives the top clamping plate 211 to move downward synchronously, and the clamping plate 211 and the positioning plate 21 on the adjusting electric push rod 22 are separated, thereby unlocking the cutter 2.

[0071] Then, the cutting depth of the cutter 2 is controlled by adjusting the electric push rod 22, and the electric slider 221 slides on the slide rail 222 to drive the cutter 2 to move horizontally, thereby cutting the steel bar 4. After the cutting is completed, the steel bar clamped by the locking sleeve 3 needs to be moved outward by one end so that the steel bars at both ends can be separated. At this time, the steel bar 4 on one side of the push plate 64 is not squeezed by external force, and the first spring 653 and the second spring 654 at this time push the push plate 64 to reset, and the pressure plate 622 and the steel bar 4 are unlocked.

[0072] Then the operator starts the material unloading electric push rod 71, which drives the sliding rod 7 to retract and move, and the sliding rod 7 slides on the bar groove 721 of the rocker arm 72, and finally drives the rocker arm 72 to rotate as a whole, and the rocker arm 72 drives the flip plate 6 installed with the steel bar 4 to rotate, and the flip plate 6 rotates around the rotation axis 722, wherein the flip plate 6 is tilted at a certain angle to facilitate the sliding of the steel bar 4 for unloading. At the initial stage of the rotation movement, the synchronous rod 641 of the side wall of the push plate 64 and the shift slider 734 are in the flip slide groove 7 32, and the relative positions of the push plate 64 and the flip plate 6 do not change at this time. The purpose of this stage is to separate the steel bar 4 and the discharge port 12. When the synchronization rod 641 and the shift slider 734 of the side wall of the push plate 64 slide on the shift slide groove 733, the shift slide groove 733 is in an inclined state, and the push plate 64 can slide on the flip plate 6 at this time. The push plate 64 pushes the steel bar 4 to move outward, achieving the purpose of unloading and ensuring that the steel bar 4 will not be stuck on the flip plate 6, affecting the unloading operation.
