Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a round steel feeder. Background Technology

[0002] The blanks for parts processed by CNC machine tools are generally round steel. Before processing, the round steel needs to be cut into blanks of appropriate length using a saw, and then the blanks are clamped on a CNC lathe for precision machining.

[0003] like Figure 1 As shown, when cutting round steel, a bracket 1 is generally needed to support the round steel 4. After cutting, the bracket 1 moves the round steel 4 a certain distance towards the sawing machine 2, and then the round steel 4 is cut again, thus cutting the round steel 4 into multiple blanks. However, in the later stages of cutting, when the length of the round steel 4 on one side of the bracket 1 is shorter, the center of gravity of the round steel 4 crosses the sawing machine 2. To prevent the round steel 4 from tilting, a support 3 needs to be set on the side of the sawing machine 2 away from the bracket 1 to support the round steel 4 and ensure that the sawing machine 2 can clamp the horizontally positioned round steel 4. Therefore, some existing feeders are inconvenient when cutting the round steel 4 in the later stages.

[0004] Patent document CN215880906U discloses an automatic feeding and unloading device for round steel bars, including a material rack, a feeding frame, a proximity switch, a clamping mechanism, and an unloading mechanism. The material rack is located on the side of the feeding frame, the proximity switch is located on the side of the tail end of the feeding frame, the clamping mechanism is located at the tail end of the feeding frame, and the unloading mechanism is located at the tail end of the clamping mechanism. The feeding frame operates to feed the material to the clamping mechanism, and together with the clamping mechanism, feeds the material to the unloading mechanism. When the tail end of the first piece of material passes the proximity switch on the side of the feeding frame, the second piece of material begins to be automatically unloaded and fed to the tail end of the first piece of material, and so on, to achieve automatic feeding.

[0005] The patent document with publication number CN221069839U discloses a round steel feeder, including a mounting frame, an adjustment mechanism on the top of the mounting frame, and a feeding mechanism on the inner side of the mounting frame;

[0006] The adjustment mechanism includes a limiting component and an auxiliary limiting component, with the auxiliary limiting component located to the right of the limiting component. During use, the limiting component moves two limiting blocks in opposite directions, reducing the distance between them and ensuring that only one round steel bar can be fed between them, preventing two round steel bars from being fed side-by-side. The auxiliary limiting component limits the height of the round steel bars with an arc-shaped block, ensuring that only one row of round steel bars can be fed at a time. When the round steel bars are standing upright, the arc-shaped block blocks the vertical bars, causing them to lie flat and thus pushing them out. The feeding mechanism pushes the round steel bars during use, allowing for the feeding of multiple round steel bars at once, increasing work efficiency.

[0007] Neither of the aforementioned patent documents provides a solution to the problem that the round steel tends to tilt during the later cutting process because its center of gravity is not on the sawing machine. Utility Model Content

[0008] The main objective of this invention is to provide a round steel feeder with good stability, ensuring the stability of the round steel even after its center of gravity has crossed the sawing machine during subsequent cutting. To achieve this objective, the technical solution provided by this invention is as follows:

[0009] A round steel feeder includes a lower plate, with support units on both sides of the upper end of the lower plate. A stabilizing component is slidably mounted on the lower plate along its length. A driving unit is installed inside the lower plate, which can drive the stabilizing component to move along the length of the lower plate. The stabilizing component includes a slide rod with a sleeve fixed on it. A lifting rod is slidably inserted into the sleeve. The lifting rod is inverted L-shaped, with its vertical part slidably inserted into the sleeve. A conical cover is fixed on the horizontal part of the lifting rod. After the lifting rod and the conical cover descend, the upper side of the tail end of the round steel can enter the conical cover. A locking screw is threaded onto the sleeve, and the locking screw abuts against the lifting rod.

[0010] Specifically, the support unit includes a side plate, the upper end of which is inclined to the outer side of the lower plate, and the lower end of the side plate is fixedly connected to the upper end of the lower plate by multiple connecting rods. A guide roller is provided between two adjacent connecting rods, the upper end of which is rotatably connected to the side plate, and the lower end of which is rotatably connected to the lower plate.

[0011] Specifically, the lower plate has a long groove, and the slide rod is slidably disposed in the long groove.

[0012] Specifically, the drive unit includes a lead screw rotatably disposed in a long slot, a motor fixed on the base plate, the output shaft of the motor being concentrically and fixedly connected to the lead screw, the lead screw passing through a slide rod, and the lead screw and slide rod being threadedly connected.

[0013] Specifically, the lower end of the lower plate is fixed with multiple support legs.

[0014] Specifically, the slide rod has a through hole concentric with the sleeve, and the vertical part of the lifting rod can pass through the through hole on the slide rod.

[0015] Specifically, the sleeve is a rectangular tube, the lifting rod has a rectangular cross-section, and the through hole is a rectangular hole.

[0016] Specifically, the motor is electrically connected to the control module, the control module is electrically connected to the PLC controller, and the PLC controller is electrically connected to the control panel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The height of the cone can be adjusted by the cooperation of the lifting rod and the sleeve. The upper side of the tail end of round steel of different diameters can be located inside the cone. Therefore, when the center of gravity of the round steel passes the saw, the cone can prevent the round steel from tilting under the blocking effect of the cone.

[0019] 2. The inclined guide rollers can effectively support the round steel and facilitate the sliding of the round steel along its length above the lower plate.

[0020] 3. The lifting rod includes a horizontal part and a vertical part, so it can push the round steel to the lower plate as a whole. When the billet length is short, the billet that has detached from the lower plate can continue to move on the saw, which can reduce the length of the remaining material head and improve the utilization rate of the round steel.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figures 1-5 As shown, a round steel feeder includes a lower plate 5, and a plurality of support legs 6 are fixed at the lower end of the lower plate 5.

[0029] Support units are provided on both sides of the upper end of the lower plate 5.

[0030] The support unit includes a side plate 14. The upper end of the side plate 14 is inclined to the outside of the lower plate 5. The lower end of the side plate 14 is fixedly connected to the upper end of the lower plate 5 by multiple connecting rods 15. A guide roller 16 is provided between two adjacent connecting rods 15. The upper end of the guide roller 16 is rotatably connected to the side plate 14, and the lower end of the guide roller 16 is rotatably connected to the lower plate 5.

[0031] A stabilizing component is slidably mounted on the lower plate 5 along its length. A driving unit is installed inside the lower plate 5, which can drive the stabilizing component to move along the length of the lower plate 5.

[0032] The stabilizing component includes a slide rod 9. A long slot 7 is formed on the lower plate 5, and the slide rod 9 is slidably disposed within the long slot 7. A sleeve 11 is fixed to the slide rod 9, and a lifting rod 12 is slidably inserted into the sleeve 11. The lifting rod 12 is inverted L-shaped, with its vertical portion slidably inserted into the sleeve 11. A conical cover 13 is fixed to the horizontal portion of the lifting rod 12. After the lifting rod 12 and the conical cover 13 descend, the upper side of the tail end of the round steel 4 can enter the conical cover 13. A locking screw 17 is threaded onto the sleeve 11, and the locking screw 17 tightly abuts against the lifting rod 12. The sleeve 11 is a rectangular tube, and the lifting rod 12 has a rectangular cross-section.

[0033] The drive unit includes a lead screw 8 rotatably disposed in a long slot 7, a motor 10 fixed on the base plate, the output shaft of the motor 10 being concentrically and fixedly connected to the lead screw 8, the lead screw 8 passing through a slide rod 9, and the lead screw 8 and the slide rod 9 being threadedly connected.

[0034] The motor 10 is electrically connected to the control module, the control module is electrically connected to the PLC controller, and the PLC controller is electrically connected to the control panel.

[0035] When material needs to be cut, the round steel bar 4 is placed between the two support units, and the guide rollers 16 on both sides can support the round steel bar 4. By setting the guide rollers 16, it is convenient for the round steel bar 4 to move between the two support units.

[0036] Move the round steel 4 so that the upper side of the tail end of the round steel 4 is inside the cone cover 13, and then loosen the locking screw 17 so that the cone cover 13 and the lifting rod 12 move downward so that the upper side of the tail end of the round steel 4 is pressed against the inner wall of the cone cover 13.

[0037] Then, motor 10 is started, driving lead screw 8 to rotate. As lead screw 8 rotates, slide bar 9, sleeve 11, lifting rod 12, and cone cover 13 push round steel 4 towards sawing machine 2. First, sawing machine 2 cuts the head end of round steel 4 to ensure it is flat. Then, the required blank length is input on the control panel. After motor 10 is started, the PLC controller controls motor 10 to rotate a set number of revolutions, ensuring the blank moves towards sawing machine 2 by a length equal to the cutting length input on the control panel. After motor 10 stops, sawing machine 2 clamps and cuts round steel 4. After sawing machine 2 finishes cutting round steel 4, it releases the round steel 4. Motor 10 starts again, causing round steel 4 to move towards sawing machine 2 again by a cutting length, and then cutting continues. Therefore, this feeder can intermittently feed round steel 4, thus completing the unloading operation.

[0038] When the round steel 4 is cut later, after the center of gravity of the round steel 4 passes the saw 2, the cone cover 13 can prevent the round steel 4 from tilting.

[0039] The lifting rod includes a horizontal part and a vertical part, so it can push the round steel as a whole to one side of the lower plate. When the length of the billet is short, the billet that has detached from the lower plate can continue to move on the saw, which can reduce the length of the remaining material head and improve the utilization rate of the round steel 4.

[0040] Example 2: Based on Example 1, referring to... Figure 5 As shown, the slide rod 9 has a through hole 18 concentric with the sleeve 11, and the vertical part of the lifting rod 12 can pass through the through hole 18 on the slide rod 9. The through hole 18 is a rectangular hole.

[0041] By setting through holes 18, the lifting range of lifting rod 12 and cone cover 13 can be increased, the diameter range of round steel 4 that this feeder can adapt to can be increased, and the upper side of the tail end of the round steel 4 can be entered into the cone cover 13 and pressed tightly against the inner wall of the cone cover 13.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
