Description

Technical Field

[0001] This utility model relates to a stainless steel bar stacking device, belonging to the field of stainless steel bar processing technology. Background Technology

[0002] In the production, storage, and processing of stainless steel bars, stacking and transfer are crucial processes. The core requirement is to use clamps to stably hold both ends of the bars, enabling efficient transfer and orderly stacking of single or multiple bars. Currently, the industry commonly uses fixed-width clamps as the clamping actuators, combined with a traversing mechanism to drive the clamps closer to or further away from the bars to complete the clamping and releasing actions.

[0003] In mass production scenarios, to improve transfer efficiency, it is often necessary to clamp multiple stainless steel bars at once. In this case, a wider clamp is required to ensure that the clamp can cover both ends of multiple bars simultaneously. However, when the production process is switched to single bars, such as when unqualified bars are extracted for separate sorting or when a single high-precision bar is extracted according to production needs, the drawbacks of the wide clamp will be fully exposed. The two sides of the clamp that extend beyond the main clamping area will obstruct and interfere with adjacent bars in the stack. This not only makes it difficult to accurately align the clamping point of the target single bar, but also causes the edge of the clamp to rub and squeeze with non-target bars, resulting in scratches on the bar surface. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a stainless steel bar stacking device, which realizes the purpose of batch clamping of multiple bars and precise clamping of a single bar.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a stainless steel bar stacking equipment, characterized in that it includes: a feeding rack, a bar material placement groove is opened at one end of the top of the feeding rack, and a rotating column is vertically arranged at the other end of the top of the feeding rack through a bearing, a horizontal plate is fixed at the top of the rotating column, and a hydraulic cylinder is fixed through the horizontal plate, a rectangular frame is arranged below the hydraulic cylinder, and a main clamping plate is arranged at both ends inside the rectangular frame, a side clamping plate is slidably connected to both sides of the main clamping plate, a slider is fixed on both sides of the main clamping plate, a sliding groove is opened on the side wall of the side clamping plate, and the slider is located in the sliding groove;

[0006] The loading rack has a drive mechanism at its internal midpoint for moving the main clamping plate laterally.

[0007] The feeding rack has adjustment mechanisms at both ends for driving the side clamps to move vertically.

[0008] The outer side of the feeding rack is fixed with a rotating mechanism for driving the rotating column to rotate.

[0009] Preferably, the output end of the hydraulic cylinder is fixed with a mounting plate, and the mounting plate is fixed to the top of the rectangular frame.

[0010] Preferably, the driving mechanism includes a bidirectional lead screw, which passes through two sets of main clamping plates and is threadedly connected to them. A guide rod is also fixed at the midpoint inside the rectangular frame, which passes through the two sets of main clamping plates and is slidably connected to them. A motor is fixed outside the rectangular frame, and the output end of the motor is connected to the bidirectional lead screw.

[0011] Preferably, rubber pads are fixed to the lower sides of both the main clamping plate and the side clamping plate.

[0012] Preferably, the adjustment mechanism includes a gear rod, which is installed on both sides inside the rectangular frame. A rack is fixed to the side wall of the side clamp, and the rack meshes with the gear rod. Motor 2 is fixed to both ends of the outer side of the rectangular frame, and the output end of motor 2 is connected to the gear rod.

[0013] Preferably, the rotating mechanism includes a third motor, the output end of which is provided with a driving wheel, and the bottom of the rotating column is fitted with a driven wheel, which meshes with the driving wheel.

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

[0015] The main clamping plate and the sliding side clamping plate are combined to form a clamping structure. The two sides of the main clamping plate are slidably connected to the sliding grooves of the side clamping plate by sliders. With the help of independent drive and adjustment mechanisms, the clamping mode can be flexibly switched. When multiple stainless steel bars need to be transferred at one time, the adjustment mechanism can drive the side clamping plate to descend to be flush with the main clamping plate. At this time, the main clamping plate and the two side clamping plates form a wide clamping surface, which can simultaneously fit the two ends of multiple bars, improving the transfer efficiency. When it is necessary to sort out unqualified bars or extract a single high-precision bar, the adjustment mechanism can drive the side clamping plate to rise along the sliding groove, leaving only the main clamping plate as the clamping body. This ensures that the main clamping plate can accurately align with the clamping point of the target single bar, improving the accuracy and reliability of single bar extraction.

[0016] Compared to traditional equipment that requires manual disassembly and replacement of clamps of different widths, this device can directly lift and lower the side clamps and move the main clamps laterally through the adjustment and drive mechanisms. The clamping mode can be switched without stopping the machine to change clamps, and the single switching time is shortened to a few seconds, which significantly improves the utilization rate of the equipment and reduces the physical labor of operators. At the same time, it avoids the clamp alignment deviation caused by manual operation and reduces the probability of equipment failure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] A stainless steel bar stacking device includes: a feeding rack 1, a bar storage trough at one top end of the feeding rack 1, and a rotating column 2 vertically arranged at the other top end of the feeding rack 1 via a bearing. A horizontal plate 3 is fixed to the top of the rotating column 2, and a hydraulic cylinder 4 is fixed through the horizontal plate 3. A rectangular frame 6 is arranged below the hydraulic cylinder 4, and main clamping plates 7 are arranged at both ends inside the rectangular frame 6. Side clamping plates 8 are slidably connected to both sides of the main clamping plates 7. Sliding blocks 9 are fixed to both sides of the main clamping plates 7. A sliding groove 10 is opened on the side wall of the side clamping plates 8, and the sliding block 9 is located in the sliding groove 10.

[0025] A drive mechanism 11 for moving the main clamping plate 7 laterally is provided at the midpoint of the interior of the feeding rack 1;

[0026] The feeding rack 1 has an adjustment mechanism 13 at both ends inside for driving the side clamping plate 8 to move vertically;

[0027] A rotating mechanism 14 for driving the rotating column 2 to rotate is fixed on the outside of the feeding rack 1.

[0028] Furthermore, the top storage slot of the loading rack 1 holds the bar stock; the rotating column 2 supports the rotation of the horizontal plate 3; the hydraulic cylinder 4 with the rectangular frame 6 lifts and aligns the bar stock; the main clamping plate 7 and the side clamping plate 8 slide and cooperate through the slider 9 and the slide groove 10; the drive mechanism 11 moves the main clamping plate 7 laterally to clamp and release; the adjustment mechanism 13 lifts and lowers the side clamping plate 8 to switch the clamping mode; and the rotation mechanism 14 rotates the rotating column 2 to adjust the stacking position.

[0029] In this embodiment: the output end of the hydraulic cylinder 4 is fixed with a mounting plate 5, and the mounting plate 5 is fixed to the top of the rectangular frame 6.

[0030] Furthermore, the mounting plate 5 at the output end of the hydraulic cylinder 4 increases the contact area with the rectangular frame 6, so that the vertical force is transmitted evenly, avoiding the rectangular frame 6 from tilting and deforming, and ensuring the stability of the clamping structure in lifting and lowering.

[0031] In this embodiment: the drive mechanism 11 includes a bidirectional lead screw 1101, which passes through two sets of main clamping plates 7 and is threadedly connected to them. A guide rod 1102 is also fixed at the midpoint inside the rectangular frame 6, which passes through the two sets of main clamping plates 7 and is slidably connected to them. A motor 1103 is fixed outside the rectangular frame 6, and the output end of the motor 1103 is connected to the bidirectional lead screw 1101.

[0032] Furthermore, the motor 1103 drives the bidirectional lead screw 1101 to rotate. Because the threads at both ends of the lead screw are reversed, it drives the two sets of main clamping plates 7 to move closer or further away. The guide rod 1102 restricts the rotation of the main clamping plate 7, allowing it to move smoothly laterally only, thus ensuring precise clamping.

[0033] In this embodiment: rubber pads 12 are fixed to the lower sides of both the main clamping plate 7 and the side clamping plate 8.

[0034] Furthermore, the rubber pads 12 below the main clamping plate 7 and the side clamping plate 8 buffer the clamping force to prevent the bar stock from being scratched, while increasing the friction to prevent the bar stock from slipping.

[0035] In this embodiment: the adjustment mechanism 13 includes a gear rod 1301, which is installed on both sides inside the rectangular frame 6. A rack 1302 is fixed to the side wall of the side clamp 8, and the rack 1302 meshes with the gear rod 1301. A second motor 1303 is fixed to both ends of the outer side of the rectangular frame 6, and the output end of the second motor 1303 is connected to the gear rod 1301.

[0036] Furthermore, the second motor 1303 drives the gear rod 1301 to rotate, and through meshing with the rack 1302, the rotational motion is converted into the vertical motion of the side clamping plate 8, realizing the switching of the side clamping plate 8 to hold one or more clamps. Since the axial length of the gear rod 1301 covers the range of the side clamping plate 8 moving laterally with the main clamping plate 7, it ensures that the rack 1302 always remains meshed with the gear rod 1301 during the lateral movement of the side clamping plate 8, and the rack 1302 will not disengage from the gear rod 1301 due to lateral displacement.

[0037] In this embodiment: the rotating mechanism 14 includes a motor 1401, the output end of the motor 1401 is provided with a driving wheel 1402, the bottom of the rotating column 2 is fitted with a driven wheel 1403, and the driven wheel 1403 meshes with the driving wheel 1402.

[0038] Furthermore, motor 3 1401 drives the drive wheel 1402 to rotate, which in turn drives the driven wheel 1403 and the rotating column 2 to rotate, thereby causing the horizontal plate 3 and the clamping structure to turn, thus realizing the transfer of bar stock.

[0039] The workflow of this embodiment is as follows: First, the stainless steel bars to be stacked are placed into the storage slot of the loading rack 1, ensuring that the ends are flush. Then, the hydraulic cylinder 4 extends, and the rectangular frame 6 descends via the mounting plate 5, so that the rubber pads 12 of the main clamping plate 7 and the side clamping plate 8 are close to both ends of the bar. Then, the motor 1103 starts, driving the bidirectional lead screw 1101 to rotate. Because the threads at both ends of the lead screw are reversed, the two sets of main clamping plates 7 move towards each other along the guide rod 1102, clamping the bar. The rubber pads 12 prevent scratches and slippage. Then, the hydraulic cylinder 4 retracts, and the rectangular frame 6 and the clamped bar rise, detaching from the storage slot. The motor 1103 then retracts. 401 starts, driving the drive wheel 1402 to rotate, meshing with the driven wheel 1403 to make the rotating column 2 rotate, which in turn drives the horizontal plate 3 and the bar to turn, placing the bar on the stacking platform. When clamping a single bar, the motor 1303 is started in the initial preparation stage, driving the gear rod 1301 to rotate, meshing with the rack 1302 to make the side clamping plate 8 rise along the slider 9 and the slide groove 10. If clamping multiple bars, the motor 1303 drives the gear rod 1301 to rotate, meshing with the rack 1302 to make the side clamping plate 8 fall along the slider 9 and the slide groove 10. After the main clamping plate 7 is flush with the side clamping plate 8, multiple bars can be clamped.
