Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and specifically to a convenient auxiliary structure for processing steel bars. Background Technology

[0002] In modern industrial production, steel bars, as an important basic material, are widely used in construction, machinery manufacturing, transportation, and other fields. During the processing of steel bars, the conveying system is a crucial link in ensuring production continuity and efficiency. Currently, most steel bar processing conveying systems use grooved rotating rollers as the conveying mechanism. Steel bars are placed within the grooves of the rollers, and the rotation of the rollers facilitates the transport of the steel bars. This conveying method has a relatively simple structure and low cost, and to a certain extent meets production needs.

[0003] However, existing steel bar conveying systems have significant drawbacks.

[0004] Because they generally lack a clamping device, the steel bars rely solely on their own weight to contact the roller grooves during transport, lacking sufficient constraint. When the steel bars are small in diameter and light in weight, the normal pressure between them and the rollers is insufficient, making it difficult to maintain stable transport due to friction, and slippage is very likely to occur. This slippage problem is even more pronounced under conditions such as high transport speeds, system start-up or emergency stops, and relatively smooth steel bar surfaces. Steel bar slippage not only significantly reduces transport efficiency and affects production progress, but may also cause the steel bars to shift in position, affecting subsequent processing accuracy; in severe cases, it can even lead to steel bar jamming or detachment from the transport track, increasing equipment maintenance costs and downtime, and reducing the stability and reliability of the entire production line.

[0005] Furthermore, as the steel bar processing industry continues to demand higher production efficiency and processing quality, the existing conveying system is no longer able to meet the growing production needs.

[0006] Therefore, there is an urgent need to design an auxiliary structure that can effectively solve the problem of steel bar slippage and improve the stability and efficiency of conveying, so as to improve the existing steel bar processing and conveying system. Utility Model Content

[0007] To address the aforementioned problems, this invention presents a convenient auxiliary structure for processing steel bars.

[0008] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0009] A convenient auxiliary structure for processing steel bars includes a base, a support seat on the left side of the top wall of the base, a drive shaft rotatably connected to the right side wall of the support seat via a bearing, a conveying wheel interference fitly connected to the right side of the outer wall of the drive shaft, a connecting seat on the right side of the top wall of the base, and a steel bar lifting and pressing mechanism on the top wall of the connecting seat.

[0010] Furthermore, the steel bar lifting and pressing mechanism includes a cylinder with an elongated hole through its side wall. A circular seat is provided on the top wall of the cylinder, and a motor is provided on the inner wall of the circular seat. Multiple sliding grooves are provided on the inner wall of the cylinder. A lead screw is rotatably connected to the upper and lower inner walls of the cylinder through bearings, and the top end of the lead screw is fixedly connected to the output end of the motor through a coupling. A circular plate is threaded onto the outer wall of the lead screw. A slider is provided on the left side wall of the circular plate, and a connecting cylinder is provided on the top wall of the circular plate. A connecting rod is provided on the right side wall of the connecting cylinder, and the right end of the connecting rod extends out of the elongated hole and is provided with a pressing mechanism.

[0011] Furthermore, the connecting sleeve is movably sleeved on the outer wall of the lead screw.

[0012] Furthermore, the clamping mechanism includes a side plate, and a rotating rod is rotatably connected to the right side wall of the side plate via a bearing. A clamping wheel is provided on the right side of the outer wall of the rotating rod.

[0013] Furthermore, the clamping wheel is located directly above the conveying wheel.

[0014] The beneficial effects of this utility model are:

[0015] This invention features an adjustable clamping wheel structure above the steel bar. A motor-driven screw moves the clamping wheel up and down, stably pressing the steel bar onto the conveyor wheel. Compared to existing technologies that rely solely on the steel bar's own weight to contact the roller, this design significantly increases the normal pressure between the steel bar and the conveyor wheel, thereby enhancing friction. This effectively prevents slippage caused by factors such as the small diameter, light weight, smooth surface of the steel bar, or changes in conveying speed, ensuring a stable and reliable steel bar conveying process.

[0016] The adjustable clamping roller structure can flexibly adjust the distance between the steel bar and the conveying roller according to the size of the steel bar. Whether the steel bar has a large or small diameter, it can be tightly fitted by adjustment, which expands the applicability of the conveying system. It can adapt to steel bars of different specifications without changing the conveying equipment, reducing the equipment modification costs and time costs incurred by enterprises due to changes in product specifications.

[0017] A stable conveying process reduces the frequency of malfunctions such as steel bar jamming and derailment, thus reducing the number of maintenance and repairs required due to equipment failures. This auxiliary structure is installed on an existing base without altering the core structure of the original conveying system, facilitating installation and maintenance, further reducing equipment maintenance costs and downtime, and improving the stability and reliability of the production line.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1-2 As shown, a convenient auxiliary structure for processing steel bars includes a base 1, a support seat 2 on the left side of the top wall of the base 1, a drive shaft 4 rotatably connected to the right side wall of the support seat 2 via a bearing 3, a conveying wheel 5 interference fitly connected to the right side of the outer wall of the drive shaft 4, a connecting seat 6 on the right side of the top wall of the base 1, and a steel bar lifting and pressing mechanism on the top wall of the connecting seat 6.

[0025] Furthermore, the steel bar lifting and pressing mechanism includes a cylinder 7, with an elongated hole 8 extending through its side wall. A circular seat 9 is located on the top wall of the cylinder 7, and a motor 10 is mounted on the inner wall of the circular seat 9. Multiple sliding grooves are formed on the inner wall of the cylinder 7. A lead screw 12 is rotatably connected to the upper and lower inner walls of the cylinder 7 via bearings 11, and the top of the lead screw 12 is fixedly connected to the output end of the motor 10 via a coupling. A circular plate 13 is threaded onto the outer wall of the lead screw 12, and a slider 14 is located on the left side wall of the circular plate 13. A connecting cylinder 15 is provided on the top wall of plate 13, and a connecting rod 16 is provided on the right side wall of the connecting cylinder 15. The right end of the connecting rod 16 extends out of the elongated hole 8 and is provided with a pressing mechanism. After the motor 10 is started, the lead screw 12 is rotated. The lead screw 12 causes the circular plate 13 to drive the slider 14, connecting cylinder 15, connecting rod 16, side plate 17, bearing 18, rotating rod 19 and pressing wheel 20 to move upward or downward. The distance between the pressing wheel 20 and the conveying wheel 5 can be adjusted according to the size of the steel rod.

[0026] Furthermore, the connecting cylinder 15 is movably sleeved on the outer wall of the lead screw 12. After the motor 10 is started, the lead screw 12 is rotated. The lead screw 12 facilitates the circular plate 13 to drive the slider 14, connecting cylinder 15, connecting rod 16, side plate 17, bearing 18, rotating rod 19 and pressure wheel 20 to move upward or downward.

[0027] Furthermore, the clamping mechanism includes a side plate 17, and a rotating rod 19 is rotatably connected to the right side wall of the side plate 17 via a bearing 18. A clamping wheel 20 is provided on the right side of the outer wall of the rotating rod 19. By moving the clamping wheel 20 upward, the distance between the clamping wheel 20 and the conveying wheel 5 can be increased, which can accommodate steel bars with larger diameters. By moving the clamping wheel 20 downward, the distance between the clamping wheel 20 and the conveying wheel 5 can be decreased, which can accommodate steel bars with smaller diameters.

[0028] Furthermore, the clamping wheel 20 is located directly above the conveying wheel 5. When the conveying wheel 5 conveys the steel bar, it causes the clamping wheel 20 to drive the rotating rod 19 to rotate through the bearing 18. The motor 10 drives the clamping wheel 20 to press against the top of the steel bar, increasing the friction between the steel bar and the conveying wheel 5, thereby improving the conveying efficiency.

[0029] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0030] One specific application of this embodiment is:

[0031] This device adopts a modular design and can be easily installed on the base 1 of an existing steel bar conveying system to achieve rapid transformation and upgrading. The specific working process is as follows:

[0032] When it is necessary to transport steel bars of different specifications, the operator starts the motor 10 through the control system. The torque output by the motor 10 drives the lead screw 12 to rotate. The lead screw 12 and the circular plate 13 are connected by threads. As the lead screw 12 rotates, the circular plate 13 rises and falls smoothly along the axial direction of the lead screw 12. The circular plate 13 is guided by the cooperation of the slider 14 and the slide groove to ensure that there is no deviation during the lifting process. At the same time, it drives the connecting cylinder 15, connecting rod 16, side plate 17 and other components to make overall linear movement.

[0033] A bearing 18 is installed on the side plate 17. The rotating rod 19 is rotatably connected to the side plate 17 through the bearing 18. The pressure wheel 20 fixedly installed at the end of the rotating rod 19 can be adjusted in height. For steel bars with larger diameters, the operator controls the motor 10 to rotate forward, so that the lead screw 12 drives the pressure wheel 20 to move upward, increasing the distance between it and the conveying wheel 5. For steel bars with smaller diameters, the operator controls the motor 10 to rotate in the opposite direction, so that the pressure wheel 20 moves downward, and the distance between the two is precisely adjusted to a suitable position.

[0034] During the steel bar conveying process, the conveying wheel 5 contacts the surface of the steel bar through the groove and drives the steel bar forward by friction. At the same time, the clamping wheel 20 is pressed against the steel bar under the action of gravity and the adjustment mechanism, forming a stable conveying structure with upper and lower clamping. When the steel bar moves, the clamping wheel 20 is subjected to friction, which drives the rotating rod 19 to rotate freely in the bearing 18, reducing the wear between the clamping wheel 20 and the steel bar and ensuring that the surface quality of the steel bar is not affected. This method of coordinated driving of upper and lower wheels significantly increases the contact pressure and friction between the steel bar and the roller compared with the traditional structure that relies solely on the conveying wheel, effectively avoiding the phenomenon of steel bar slippage and achieving a high-speed and stable conveying effect.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
