Description

Technical Field

[0001] This utility model relates to the field of steel bar production technology, specifically to a guide wheel adjustment assembly for steel bar production. Background Technology

[0002] In the industrial production of steel bars, the guide wheel assembly is a key functional unit on the continuous production line. Its main function is to accurately guide and position the steel bars during the rolling or traction process. According to CN112758770B, a feeding and positioning guide device for rebar production is disclosed. This technology discloses a technical solution that includes a rectangular shell, a T-shaped movable plate, a first drive cylinder, a conical support block, a servo motor, an L-shaped mounting plate, a second drive cylinder, a positioning drive wheel, and guide wheels. The first drive cylinder drives the T-shaped movable plate and the conical support block to move upward to a suitable position, and the conical support block supports and places the end of the rebar. Then, the two second drive cylinders drive the two L-shaped mounting plates to move inward, thereby using the two guide wheels and the two positioning drive wheels to clamp the rebar and thus achieve positioning and placement of the rebar. The two servo motors drive the two positioning drive wheels to rotate relative to each other, thereby driving the rebar to move. During this process, the two guide wheels guide the rebar to ensure the quality of subsequent rebar processing, improve product quality, and ensure high safety. Existing steel bar production guiding devices generally suffer from the problem that the left and right side guide wheels cannot be adjusted synchronously and symmetrically when adjusting the spacing between the side guide wheels. This results in asynchronous contact between the guide wheels and the steel bars, generating eccentric forces that cause the steel bars to skew, twist, and scratch their surfaces during the guiding process. At the same time, the asymmetrical clamping forces also cause accelerated wear on one side of the guide wheels, affecting the service life and guiding accuracy of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a guide wheel adjustment assembly for rebar production. Through bidirectional linkage adjustment, it achieves synchronous clamping of the upper and lower guide wheels and symmetrical guidance of the side guide wheels, ensuring that the rebar is transported in the center, effectively preventing deviation and wear, and improving guiding accuracy and production stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide wheel adjustment assembly for rebar production, comprising a base, wherein a guide mechanism is provided on the base for guiding the rebar, and the guide mechanism includes: The main components include side frames fixed to the left and right ends of the base, and a cross frame fixed between the upper ends of the two side frames; The longitudinal guide assembly includes support rods pivotally connected to the rear end of the base and the left and right sides of the rear end of the cross frame. Side guide wheels are fixed between the upper and lower support rods. A protruding rod is rotatably installed on the upper end of the side guide wheel. An internal threaded seat is fixed on the top of the cross frame. A first handwheel screw is installed through the internal threaded seat. A guide frame is rotatably installed on the front end of the first handwheel screw. Guide grooves are opened on both the left and right sides inside the guide frame, and the protruding rod is located inside the guide groove. The lateral guide assembly includes a lower axle seat that is slidably mounted inside the lower end of the side frame, a lower guide wheel that is rotatably mounted between the two lower axle seats, an upper axle seat that is slidably mounted inside the upper end of the side frame, and an upper guide wheel that is rotatably mounted between the two upper axle seats.

[0005] Preferably, the lateral guide assembly further includes a second handwheel screw threaded through and mounted on the upper end of the side frame, and the lower end of the second handwheel screw is rotatably connected to the upper end of the upper shaft seat.

[0006] Preferably, the transverse guide assembly further includes a shaft plate fixed to the outer wall of the side frame, a rotating rod rotatably mounted on the outer wall of the shaft plate, and connecting rods pivotally connected to both ends of the rotating rod, with the other ends of the two connecting rods respectively rotatably connected to the lower guide wheel and the upper guide wheel.

[0007] Preferably, the guide grooves on the left and right sides inside the shaft plate are arranged symmetrically, and the support rods on the left and right sides are arranged symmetrically.

[0008] Preferably, the side frame is provided with a vertical groove for limiting the sliding trajectory of the lower and upper shaft seats.

[0009] Preferably, the wheel surface of the side guide wheel is arranged perpendicular to the wheel surfaces of the lower guide wheel and the upper guide wheel.

[0010] Beneficial effects This invention provides a guide wheel adjustment assembly for rebar production. Compared with the prior art, it has the following advantages: 1. The guide frame moves back and forth by rotating the first handwheel screw. The sliding engagement of the symmetrically arranged guide grooves on both sides with the protruding rods at the upper ends of the side guide wheels forces the support rods pivotally connected to the rear end of the base and the rear end of the crossbeam to move synchronously. When the guide frame moves backward, the guide grooves push the protruding rods towards each other, causing the upper parts of the support rods to retract inward, reducing the distance between the side guide wheels. When the guide frame moves forward, the guide grooves release the protruding rods, causing the upper parts of the support rods to expand outward under gravity or the action of the reinforcing bars, increasing the distance between the side guide wheels. This achieves synchronous, equidistant, stepless adjustment of the distance between the side guide wheels, allowing it to adapt to the width requirements of different specifications of reinforcing bars. This ensures that the reinforcing bars remain centered and aligned during longitudinal guidance, effectively preventing scraping, jamming, or unstable guidance caused by inappropriate spacing, greatly improving guidance accuracy and equipment adaptability.

[0011] 2. By rotating the second handwheel screw, the upper shaft seat slides vertically along the inside of the side frame, thereby causing the upper guide wheel to rise and fall synchronously. The upper guide wheel drives the rotating rod to rotate through the connecting rod connected to it, and then drives the lower shaft seat and its lower guide wheel to move synchronously in the opposite direction through the connecting rod on the other side, thereby realizing the relative or opposite movement of the upper and lower guide wheels. This ensures that the upper and lower guide wheels always maintain symmetrical movement with the center line of the rebar as the reference, ensuring that the rebar is always in the guide center position, avoiding unilateral wear, surface scratches and bending deformation caused by asymmetrical clamping, and improving the guiding accuracy and the stability of equipment operation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a guide wheel adjustment assembly for rebar production, including a base 1, a guide mechanism 2 on the base 1 for guiding the rebar, the guide mechanism 2 including: The main component 21 includes side frames 211 fixed at the left and right ends of the base 1, and a cross frame 212 fixed between the upper ends of the two side frames 211. The longitudinal guide assembly 22 includes support rods 221 pivotally connected to the rear end of the base 1 and the left and right sides of the rear end of the cross frame 212. Side guide wheels 222 are fixed between the upper and lower support rods 221. A protruding rod 223 is rotatably installed on the upper end of the side guide wheel 222. An internal thread seat 224 is fixed on the top of the cross frame 212. A first handwheel screw 225 is threaded through the internal thread seat 224. A guide frame 226 is rotatably installed at the front end of the first handwheel screw 225. Guide grooves 227 are opened on both the left and right sides inside the guide frame 226, and the protruding rod 223 is located inside the guide groove 227. The transverse guide assembly 23 includes a lower shaft seat 231 slidably mounted inside the lower end of the side frame 211, a lower guide wheel 232 rotatably mounted between the two lower shaft seats 231, an upper shaft seat 233 slidably mounted inside the upper end of the side frame 211, and an upper guide wheel 234 rotatably mounted between the two upper shaft seats 233.

[0016] In this embodiment, the guide frame 226 is driven to move back and forth by rotating the first handwheel screw 225. The guide grooves 227 symmetrically arranged on its left and right sides slide against the protrusions 223 at the upper ends of the left and right side guide wheels 222, forcing the support rods 221 pivotally connected to the rear ends of the base 1 and the crossbeam 212 to move synchronously. When the guide frame 226 moves backward, the guide grooves 227 push the protrusions 223 to move towards each other, causing the upper parts of the support rods 221 to retract inward, reducing the distance between the side guide wheels 222. When the guide frame 226 moves forward, the guide grooves 227 on both sides release the protruding rods 223, causing the upper part of the support rods 221 on both sides to expand outward under the action of gravity or steel bars, increasing the distance between the side guide wheels 222 on both sides; thus realizing the synchronous and stepless adjustment of the distance between the side guide wheels 222 on both sides, enabling it to adapt to the width requirements of steel bars of different specifications, ensuring that the steel bars remain centered and aligned during the longitudinal guidance process, effectively preventing steel bar scraping, jamming or unstable guidance caused by unsuitable spacing, and greatly improving the guiding accuracy and equipment adaptability.

[0017] Specifically, the transverse guide assembly 23 also includes a second handwheel screw 235 that is threaded through and installed on the upper end of the side frame 211, and the lower end of the second handwheel screw 235 is rotatably connected to the upper end of the upper shaft seat 233.

[0018] In this embodiment, rotating the second handwheel screw 235 drives the upper shaft seat 233 to slide vertically along the inside of the side frame 211, thereby driving the upper guide wheel 234 to rise and fall synchronously.

[0019] Specifically, the transverse guide assembly 23 also includes a shaft plate 236 fixed to the outer wall of the side frame 211. A rotating rod 237 is rotatably mounted on the outer wall of the shaft plate 236. Both ends of the rotating rod 237 are pivotally connected to connecting rods 238, and the other ends of the two connecting rods 238 are rotatably connected to the lower guide wheel 232 and the upper guide wheel 234, respectively.

[0020] In this embodiment, when the upper shaft seat 233 drives the upper guide wheel 234 to move vertically, the connecting rod 238 connected to it drives the rotating rod 237 to rotate, and then the connecting rod 238 on the other side drives the lower shaft seat 231 and its lower guide wheel 232 to move in opposite directions synchronously, thereby realizing the relative or opposite movement of the upper and lower guide wheels; ensuring that the upper and lower guide wheels always maintain symmetrical movement with the center line of the steel bar as the reference, ensuring that the steel bar is always in the guide center position, avoiding the problems of unilateral wear, surface scratches and bending deformation caused by asymmetrical clamping, and improving the guiding accuracy and the stability of equipment operation.

[0021] Specifically, the guide grooves 227 on the left and right sides inside the shaft plate 236 are symmetrically arranged, and the support rods 221 on the left and right sides are symmetrically arranged.

[0022] Specifically, the side frame 211 has vertical slots for limiting the sliding trajectory of the lower bearing 231 and the upper bearing 233.

[0023] Specifically, the wheel surface of the side guide wheel 222 is arranged perpendicularly to the wheel surfaces of the lower guide wheel 232 and the upper guide wheel 234.

[0024] The working principle and usage process of this utility model are as follows: First, the lateral spacing is adjusted according to the specifications of the reinforcing bars. By rotating the second handwheel screw 235, the upper shaft seat 233 is driven to move the upper guide wheel 234 downward. At this time, the connecting rod 238 pushes the rotating rod 237 to rotate, and then the connecting rod 238 on the other side synchronously drives the lower shaft seat 231 and its lower guide wheel 232 to move upward, realizing the equidistant movement of the upper and lower guide wheels and forming a clamping channel suitable for the diameter of the reinforcing bars. Next, the longitudinal width is adjusted. By rotating the first handwheel screw 225, the guide frame 226 is driven to move backward, and the guides arranged symmetrically inside it move backward. The inclined groove 227 pushes the two protruding rods 223 to move towards each other, causing the upper part of the support rod 221, which is pivotally connected to the base 1 and the cross frame 212, to retract inward, so that the distance between the left and right side guide wheels 222 is reduced to match the width of the steel bar; after completing the bidirectional adjustment, the steel bar is sent into the three-dimensional guide channel composed of the lower guide wheel 232, the upper guide wheel 234 and the side guide wheel 222. The upper and lower guide wheels are responsible for the vertical limiting clamping, and the side guide wheels are responsible for the horizontal guiding and positioning; if fine adjustment is required during the conveying process, it can be precisely adjusted at any time through the two handwheel screws to ensure that the steel bar always remains centered and aligned.
