Description

Technical Field

[0001] This utility model relates to the technical field of cold-rolled ribbed steel bar production equipment, specifically a feeding device for a cold-rolled ribbed steel bar production line. Background Technology

[0002] Cold-rolled ribbed steel bars are steel bars with two or three crescent shapes formed by multiple cold rolling reductions of hot-rolled round steel, one rib pressing, and stress relief. Due to their high steel strength, which can save construction steel and reduce project costs, good bonding and anchoring performance between cold-rolled ribbed steel bars and concrete, and greater elongation than similar cold-worked steels, they are widely used in cast-in-place concrete structures in the construction industry.

[0003] According to the publicly disclosed feeding device for a cold-rolled ribbed steel bar production line (Announcement No.: CN215657072U), the above application includes a material placement rack and a feeding rack; the material placement rack includes a tilting base and a support, with the support fixedly installed on the tilting base; the feeding rack includes a vertically installed upright, with a first guide wheel assembly at the bottom of the upright; a guide frame is horizontally installed on the top of the upright, with a guide assembly on the guide frame.

[0004] However, in actual use, the above-mentioned feeding device requires the hot-rolled round steel coils to be placed on the support. This requires lifting the hot-rolled round steel coils to the top of the support. Generally, hot-rolled round steel coils are heavy, and manual lifting poses a high safety risk, which may cause them to slip and fall and cause injury. In view of this, we propose a feeding device for a cold-rolled ribbed steel bar production line. Summary of the Invention

[0005] The purpose of this utility model is to provide a feeding device for a cold-rolled ribbed steel bar production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a cold-rolled ribbed steel bar production line, comprising a frame, a guide wheel rotatably connected to the inner wall of the frame, and a guide assembly provided on the side wall of the frame, the guide assembly comprising:

[0007] A drive motor is provided, with a threaded rod fixedly connected to the output end of the drive motor. A movable frame is threadedly connected to the side wall of the threaded rod. A guide wheel is rotatably connected to the inner wall of the movable frame. A guide sleeve is fixedly connected to the bottom end face of the movable frame.

[0008] A base body, the top end face of which is hinged to a hinge frame, the top end face of which is fixedly connected to a bracket, the inner wall of which is fixedly connected to a rotating shaft, and the side wall of which is fitted with a limit frame.

[0009] Preferably, the drive motor is fixedly connected to the inner bottom surface of the frame, the movable frame is slidably connected to the frame, and the drive motor drives the threaded rod to rotate, so that the movable frame moves longitudinally.

[0010] Preferably, there are two sets of the hinge frame and the bracket, and the two sets of brackets are arranged at an angle, with the angle of the brackets facing the guide sleeve.

[0011] Preferably, the base is fixedly connected to the side wall of the frame, and two sets of limiting frames are provided, with the two sets of limiting frames interlocked together.

[0012] Preferably, the hot-rolled round steel strip passes sequentially through the limiting frame, guide sleeve, guide wheel two, and guide wheel one, with the hot-rolled round steel strip being guided by guide wheel two and guide wheel one.

[0013] Preferably, the guide sleeve is funnel-shaped and has a large-diameter end and a small-diameter end, with the large-diameter end located below the guide sleeve.

[0014] Preferably, a rubber sleeve is fixedly connected to the side wall of the rotating shaft, and the end face of the rubber sleeve is movably connected to the limiting frame.

[0015] Compared with the prior art, this utility model provides a feeding device for a cold-rolled ribbed steel bar production line, which has the following beneficial effects:

[0016] 1. The feeding device of this cold-rolled ribbed steel bar production line, through the setting of a guide component, rotates the hinge frame to change the support from a vertical state to a horizontal state, so that the coiled hot-rolled round steel bars can be inserted horizontally, and then rotates back to a vertical state to complete the feeding. This reduces the feeding height, and the operators do not need to lift the steel plate high or climb to work, which greatly reduces the risk of personnel injury and significantly improves safety. The limiting frame forms a threading channel, guides and limits the round steel bars. When the round steel bars are passed out, they can only be pulled out one turn at a time, avoiding multiple turns being brought out at once, preventing the round steel bars from getting tangled, jumping off the plate, or popping out, improving the smoothness of the round steel bar output, and making the entire line operate stably.

[0017] 2. The feeding device of this cold-rolled ribbed steel bar production line increases the friction between the limiting frame and the rotating shaft by setting a rubber sleeve, so that when only one side of the limiting frame is unfolded, its angle does not droop and it is kept at a specified angle. At this time, the other set of hinged frames and supports can be fed, which facilitates independent feeding on both sides and improves feeding efficiency and stability. Attached Figure Description

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a feeding device for a cold-rolled ribbed steel bar production line, including a frame 1, a guide wheel 2 rotatably connected to the inner wall of the frame 1, and a guide assembly 3 provided on the side wall of the frame 1. The guide assembly 3 includes a drive motor 301, a threaded rod 302, a moving frame 303, a guide wheel 304, a guide sleeve 305, a seat 306, a hinge frame 307, a bracket 308, a rotating shaft 309, and a limiting frame 310.

[0026] In one embodiment of this utility model, a drive motor 301 is fixedly connected to the inner bottom surface of the frame 1. A threaded rod 302 is fixedly connected to the output end of the drive motor 301. A movable frame 303 is threadedly connected to the side wall of the threaded rod 302. A guide wheel 304 is rotatably connected to the inner wall of the movable frame 303. A guide sleeve 305 is fixedly connected to the bottom end face of the movable frame 303. The movable frame 303 is slidably connected to the frame 1. The drive motor 301 drives the threaded rod 302 to rotate, causing the movable frame 303 to move longitudinally.

[0027] The base 306 is fixedly connected to the side wall of the frame 1. The top end face of the base 306 is hinged to a hinge frame 307. The top end face of the hinge frame 307 is fixedly connected to a bracket 308. There are two sets of hinge frames 307 and brackets 308. The two sets of brackets 308 are set at an angle. The angle of the brackets 308 is towards the guide sleeve 305. The inner wall of the bracket 308 is fixedly connected to a rotating shaft 309. The side wall of the rotating shaft 309 is sleeved with a limiting frame 310. There are two sets of limiting frames 310. The two sets of limiting frames 310 are interlocked together.

[0028] The hot-rolled round steel strip passes through the limiting frame 310, guide sleeve 305, guide wheel 2 304 and guide wheel 1 2 in sequence. The hot-rolled round steel strip is guided by guide wheel 2 304 and guide wheel 1 2. The guide sleeve 305 is flared and has a large diameter end and a small diameter end. The large diameter end is located below the guide sleeve 305.

[0029] During the initial threading, the drive motor 301 drives the threaded rod 302 to rotate, causing the moving frame 303 to move downwards. The hinge frame 307 rotates, turning the support 308 horizontally, thus facilitating the loading of the coiled hot-rolled round steel. This connects the hot-rolled round steel on the two sets of supports 308 end-to-end. After the hot-rolled round steel is placed on the support 308, the hinge frame 307 is rotated in the opposite direction to reset the support 308. The hot-rolled round steel strip then passes sequentially through the guide sleeve 305, guide wheel 2 304, and guide wheel 1 2. Guide wheels 2 304 and 1 2 guide the hot-rolled round steel strip, and then the drive motor... 301 drives the threaded rod 302 to rotate in the opposite direction, causing the moving frame 303 to move upward. Since the descaling machine, rolling mill and other equipment in the cold-rolled ribbed steel bar production line are equipped with traction components, the hot-rolled round steel can be pulled by the traction of the other equipment to achieve automatic feeding. By rotating the hinge frame 307, the support 308 is changed from a vertical state to a horizontal state so that the coiled hot-rolled round steel can be inserted horizontally. Then it is turned back to the vertical state to complete the feeding, reducing the feeding height. Operators do not need to lift the steel coil high or climb to work, which greatly reduces the risk of personnel injury and significantly improves safety.

[0030] Rotate the hinge frame 307 to interlock the two sets of hinge frames 307 together. The hot-rolled round steel passes through the limiting frame 310, preventing a few coils of hot-rolled round steel from being pulled out of the support 308 at the same time during traction. After storage and transportation, the outer coils of hot-rolled round steel often partially stick together due to compaction, oxidation, or residual stress. When the strip is initially pulled, the outer coils are not fully separated, and several coils of round steel may be pulled out at once. Interlock the two sets of hinge frames 307 and pass the round steel through the limiting frame 310. The limiting frame 310 forms a threading channel, guiding and limiting the round steel. When the round steel passes through it, it can only be pulled out one coil at a time, avoiding multiple coils being pulled out at once, preventing the round steel from tangling, jumping off the plate, or popping out, improving the smoothness of the round steel output, and making the whole line run stably.

[0031] In addition, a rubber sleeve 4 is fixedly connected to the side wall of the rotating shaft 309. The end face of the rubber sleeve 4 is movably connected to the limiting frame 310. The rubber sleeve 4 increases the friction between the limiting frame 310 and the rotating shaft 309, so that when only one side of the limiting frame 310 is unfolded, its angle does not droop and it remains at a specified angle. At this time, the other set of hinged frames 307 and brackets 308 can be loaded, which facilitates independent loading on both sides and improves loading efficiency and stability.

[0032] In this invention, during use, the hinge frame 307 is rotated to turn the support 308 horizontally, facilitating the loading of hot-rolled round steel into coils. This connects the hot-rolled round steel on the two sets of supports 308 end to end. After the hot-rolled round steel is placed on the support 308, the hinge frame 307 is rotated in the opposite direction to reset the support 308, lowering the loading height. Operators do not need to lift the steel coil high or climb to work, greatly reducing the risk of injury. Rotating the hinge frame 307 interlocks the two sets of hinge frames 307, allowing the hot-rolled round steel to pass through the limiting frame 310. The limiting frame 310 forms a threading channel, guiding and limiting the round steel. When the round steel passes through it, it can only be pulled out one coil at a time, preventing multiple coils from being pulled out at once and avoiding entanglement, coil jumping, or ejection of the round steel.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
