Description

Technical Field

[0001] This utility model relates to the field of bar and wire rolling technology, and in particular to a cutting device for bar and wire rolling processing. Background Technology

[0002] In the total national steel production, bar and wire rod production accounts for 40%. Bar and wire rod have a wide range of uses. Apart from rebar and wire rod used directly as finished products in construction, they generally need to undergo further processing to become finished products. During the rolling process, bar and wire rod need to be cut, but the existing cutting equipment is not efficient enough and it is difficult to limit the running trajectory of the bar and wire rod, thus failing to guarantee the cutting quality.

[0003] For example, a cutting device for bar and wire rolling processing disclosed in Chinese patent literature (publication number: CN215314714U) not only increases the cutting efficiency of the device by fixing one end of the bar and wire and manually pushing one end of the bar and wire towards the bottom of the cutter, but also limits the running trajectory of the bar and wire, thus ensuring the cutting quality.

[0004] However, in the bar and wire cutting process, because the lower end is suspended and lacks effective support, the bar and wire are prone to shaking due to uneven force when the cutter falls at high speed to perform the cutting operation. This shaking is directly reflected in the cut, resulting in burrs, unevenness, or even severe skewing, which greatly reduces the cutting quality and cannot meet the requirements of high-precision processing. Furthermore, after each cutting operation, the bar and wire must be manually pushed downwards towards the cutter to prepare for the next cut, which requires a large amount of manual labor and greatly reduces cutting efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the current methods for cutting bar and wire rods suffer from poor stability, resulting in reduced cutting quality. Furthermore, the need for manual pushing of the bar and wire rods not only increases labor costs but also reduces cutting efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for bar and wire rolling processing, including a cutting table, a first V-shaped support block fixedly connected to the upper end of the cutting table, a clamping and cutting mechanism provided at the upper end of the cutting table, and the clamping and cutting mechanism including a first bracket, a hydraulic cylinder fixedly installed on the inner wall of the first bracket, and an installation plate fixedly connected to one end of the piston rod of the hydraulic cylinder.

[0007] A cutter is fixedly connected to the lower end of the mounting plate. Symmetrically distributed movable holes are opened at the upper end of the mounting plate. Movable rods are movably sleeved on the inner walls of the movable holes. A first V-shaped pressure block is fixedly connected to the lower end of the movable rod. A symmetrically distributed guide rod is fixedly connected to the upper end of the first V-shaped pressure block. One end of the guide rod passes through and extends to the upper end of the mounting plate. A support spring is movably sleeved on the outside of the movable rod. One end of the support spring is fixedly connected to the upper end of the first V-shaped pressure block, and the other end of the support spring is fixedly connected to the lower end of the mounting plate. A feeding mechanism is provided at the upper end of the cutting table.

[0008] Optionally, the feeding mechanism includes a second bracket, on the inner wall of which a first servo electric cylinder is fixedly installed.

[0009] Optionally, a second V-shaped pressure block is fixedly connected to one end of the piston rod of the first servo electric cylinder, a sliding groove is provided at the upper end of the cutting table, and a servo motor is fixedly installed on one side of the cutting table.

[0010] Optionally, the output shaft of the servo motor is fixedly mounted with a lead screw via a coupling. One end of the lead screw passes through and extends into the interior of the sliding groove, and the outer end of the lead screw is rotatably connected to the inner wall of one side of the sliding groove via a bearing.

[0011] Optionally, the lead screw has an external threaded connection with a threaded block, the outside of which is slidably connected to the inner wall of the sliding groove, and a movable frame is fixedly connected to the upper end of the threaded block.

[0012] Optionally, a second V-shaped support block is fixedly connected to the inner bottom wall of the movable frame, and a second servo electric cylinder is fixedly installed at the upper end of the movable frame.

[0013] Optionally, one end of the piston rod of the second servo electric cylinder passes through the moving frame and is fixedly connected to a third V-shaped pressure block. An inclined guide platform is fixedly connected to the upper end of the cutting table, and one side of the inclined guide platform contacts one side of the first V-shaped support block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the combined use of the clamping and cutting mechanism and the feeding mechanism achieves automated conveying of bar and wire materials, which not only reduces manual labor but also improves the cutting efficiency of bar and wire materials. Furthermore, by stably pressing and limiting the bar and wire materials before cutting, the phenomenon of uneven force on the bar and wire materials is avoided, thereby improving the flatness of the cut.

[0022] Example

[0023] like Figure 1-4 As shown, this utility model provides a cutting device for bar and wire rolling processing, including a cutting table 1. A first V-shaped support block 2 is fixedly connected to the upper end of the cutting table 1. The V-shaped groove of the first V-shaped support block 2 can accurately adapt to the circular cross-section of the bar and wire, forming a stable support for the bar and wire from both sides, effectively preventing the bar and wire from rolling laterally during the cutting process, ensuring accurate positioning of the cutting operation, and the first V-shaped support block 2 is provided with an avoidance groove that cooperates with the cutter 33 to cut in.

[0024] The upper end of the cutting table 1 is equipped with a clamping and cutting mechanism, which includes a first bracket 3. A hydraulic cylinder 31 is fixedly installed on the inner wall of the first bracket 3. One end of the piston rod of the hydraulic cylinder 31 is fixedly connected to a mounting plate 32. When the hydraulic cylinder 31 receives a work command and starts, the piston rod will quickly extend or retract, accurately driving the mounting plate 32 to move linearly in the up and down direction, providing power for the subsequent cutting action.

[0025] The lower end of the mounting plate 32 is fixedly connected to a cutter 33. The cutter 33 is made of high-strength, high-hardness alloy material. The blade is finely ground and extremely sharp, which can easily cut into the bar wire and ensure a neat and clean cut.

[0026] The upper end of the mounting plate 32 has symmetrically distributed movable holes 34. The inner wall of the movable holes 34 is movably sleeved with a movable rod 35. The lower end of the movable rod 35 is fixedly connected to a first V-shaped pressure block 36. When the mounting plate 32 moves downward, the first V-shaped pressure block 36 will contact the bar wire first and press the bar wire from above. Together with the first V-shaped support block 2 below, it can achieve all-round tight clamping of the bar wire and prevent the bar wire from shifting or shaking due to uneven force at the moment of cutting.

[0027] The upper end of the first V-shaped pressure block 36 is fixedly connected to symmetrically distributed guide rods 37. One end of the guide rod 37 passes through and extends to the upper end of the mounting plate 32. A support spring 38 is movably sleeved on the outside of the movable rod 35. One end of the support spring 38 is fixedly connected to the upper end of the first V-shaped pressure block 36, and the other end of the support spring 38 is fixedly connected to the lower end of the mounting plate 32. Before cutting, the support spring 38 is in a naturally extended state, giving the first V-shaped pressure block 36 a certain pre-pressure so that it can fit tightly against the bar wire. When the cutting is completed and the mounting plate 32 rises, the support spring 38 can use its own elastic restoring force to assist the first V-shaped pressure block 36 to quickly return to its position, preparing for the next cutting.

[0028] A feeding mechanism is provided at the upper end of the cutting table 1.

[0029] The feeding mechanism includes a second bracket 4, and a first servo electric cylinder 41 is fixedly installed on the inner wall of the second bracket 4.

[0030] A second V-shaped pressure block 42 is fixedly connected to one end of the piston rod of the first servo electric cylinder 41. A sliding groove 43 is provided on the upper end of the cutting table 1. A servo motor 44 is fixedly installed on one side of the cutting table 1. Under the drive of the first servo electric cylinder 41, the second V-shaped pressure block 42 can quickly descend and cooperate with the first V-shaped support block 2 on the cutting table 1 to perform initial clamping of the bar wire, laying the foundation for the stable operation of subsequent cutting processes.

[0031] The output shaft of the servo motor 44 is fixedly mounted with a lead screw 45 via a coupling. One end of the lead screw 45 passes through and extends into the interior of the sliding groove 43. The outer side of one end of the lead screw 45 is rotatably connected to the inner wall of one side of the sliding groove 43 via a bearing. The selection of the coupling ensures the connection rigidity and concentricity between the output shaft of the servo motor 44 and the lead screw 45, minimizing energy loss and vibration during power transmission.

[0032] The lead screw 45 is externally threaded with a threaded block 46. The thread fit between the threaded block 46 and the lead screw 45 is extremely precise. When the lead screw 45 rotates, the threaded block 46 can achieve precise linear displacement according to the pitch of the lead screw 45, efficiently converting rotational motion into linear motion.

[0033] The outer side of the threaded block 46 is slidably connected to the inner wall of the sliding groove 43. The upper end of the threaded block 46 is fixedly connected to the moving frame 47. The sliding groove 43 provides a stable guiding constraint for the movement of the threaded block 46, ensuring that the threaded block 46 will not deviate or shake during the movement, thus ensuring the accuracy of feeding.

[0034] A second V-shaped support block 48 is fixedly connected to the inner bottom wall of the moving frame 47, and a second servo electric cylinder 49 is fixedly installed at the upper end of the moving frame 47. The second V-shaped support block 48 works in conjunction with the moving frame 47 to continuously support the bar wire from below during the bar wire conveying process. Combined with the relevant pressure block structure above, it ensures that the bar wire maintains a stable posture during the conveying process.

[0035] One end of the piston rod of the second servo electric cylinder 49 passes through the moving frame 47 and is fixedly connected to the third V-shaped pressure block 410. Driven by the second servo electric cylinder 49, the third V-shaped pressure block 410 can move up and down flexibly and cooperate with the second V-shaped support block 48 below to achieve precise clamping of the bar wire in the moving frame 47, meeting the needs of fixing the bar wire under different working conditions.

[0036] The upper end of the cutting table 1 is fixedly connected to the inclined guide table 411. One side of the inclined guide table 411 contacts one side of the first V-shaped support block 2. When the cut bar wire moves to the inclined guide table 411 under the push of the subsequent mechanism, it can smoothly roll out along the inclined surface by its own gravity, realizing an automated unloading process and greatly improving production efficiency.

[0037] Workflow:

[0038] Step 1: The operator passes the wire rod through the moving frame 47 and places it on the upper end of the first V-shaped support block 2 and the second V-shaped support block 48. Then, the first servo electric cylinder 41 is activated to drive the second V-shaped pressure block 42 to move downwards. The first V-shaped support block 2 initially clamps the wire rod. Then, the piston rod of the hydraulic cylinder 31 is activated to extend, thereby driving the mounting plate 32 to move downwards. The downward movement of the mounting plate 32 further clamps and limits the wire rod on both sides of the cutter 33 through the two first V-shaped pressure blocks 36. As the mounting plate 32 continues to move downwards, the support spring 38 contracts with the cooperation of the guide rod 37 until the cutter 33 moves downwards and cuts the wire rod.

[0039] Step 2: After cutting is completed, the piston rod of hydraulic cylinder 31 retracts, thereby driving the cutter 33 and the first V-shaped pressure block 36 to rise and reset via mounting plate 32. At this time, the second servo electric cylinder 49 drives the third V-shaped pressure block 410 to descend and move, and after the second V-shaped support block 48 clamps the bar wire to be cut, the piston rod of the first servo electric cylinder 41 is started to retract, so that the second V-shaped pressure block 42 is disengaged from the bar wire.

[0040] Step 3: Then, start the servo motor 44 to drive the lead screw 45 to rotate. The rotation of the lead screw 45 drives the threaded block 46 to move through the sliding groove 43. The movement of the threaded block 46 drives the bar wire to be cut to move and feed through the moving frame 47. The cut bar wire is squeezed out of the first V-shaped support block 2 and rolled out through the inclined guide table 411. When it reaches the cutting size, the servo motor 44 stops working, and the first servo electric cylinder 41 drives the second V-shaped pressure block 42 to move down and move, and continues to clamp the bar wire in the first V-shaped support block 2 to facilitate subsequent cutting.
