Description

Technical Field

[0001] This utility model relates to the field of bolt production technology, and more specifically, to a slow-speed feeding rack for a bolt forming machine. Background Technology

[0002] In the bolt production process, the feeding stage of the bolt forming machine usually requires a worktable to support and transport the wire rod or wire for subsequent drawing, forming, and other processing steps. However, in actual use, the existing bolt forming machine feeding racks cause the worktable to rotate continuously due to the tension and inertia of the wire rod or wire during the drawing and feeding process. As processing progresses, the speed of the worktable tends to gradually increase. This uncontrolled speed can lead to unstable conveying speed of the wire rod or wire, which may not only cause uneven stretching, bending, or deformation of the material, but also cause the material to be conveyed too quickly due to excessive speed, exceeding the processing rhythm of subsequent steps, resulting in equipment malfunctions such as jamming, material jamming, or even shutdown, thus affecting production efficiency. Therefore, we propose a slow-speed feeding rack for bolt forming machines to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a slow-speed feeding rack for a bolt forming machine. This solves the problem that in the actual use of existing bolt forming machine feeding racks, the tension and inertia of the wire rod or coil during the feeding process cause the worktable to rotate continuously. As processing progresses, the speed of the worktable tends to gradually increase. This loss of speed control leads to unstable conveying speed of the wire rod or coil, which may not only cause uneven stretching, bending, or deformation of the material, but also cause the material to be conveyed too quickly due to excessive speed, exceeding the processing rhythm of subsequent steps, resulting in equipment malfunctions such as jamming, material jamming, or even shutdown, thus affecting production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A slow-speed feeding rack for a bolt forming machine includes a worktable. A transmission rod is installed in the middle of the lower surface of the worktable. A base is engaged at the lower end of the transmission rod. A reduction mechanism is installed between the transmission rod and the base. The reduction mechanism includes a brake ring and a fixing block. The brake ring is installed on the lower surface of the transmission rod, and the upper end of the base is engaged inside the brake ring. A plane bearing is installed inside the brake ring, and the upper and lower ends of the plane bearing are in contact with the transmission rod and the base. The fixing block is installed on the upper end of one side of the base. A support block is installed on the upper surface of the fixing block away from the brake ring. A lead screw is threaded through the inside of the support block. A movable block is movably installed on the upper surface of the fixing block. The end of the lead screw near the brake ring is connected to the movable block. A friction plate is installed on the side of the movable block near the base, and the friction plate is in contact with the brake ring.

[0006] Preferably, the upper surface of the workbench is provided with several grooves, and threaded rods are movably installed inside the grooves. Nuts are installed on the outer side of the threaded rods located at the upper end of the workbench via threads.

[0007] Preferably, a support frame is installed between the lower surface of the fixing block and the base.

[0008] Preferably, a turntable is installed at the end of the lead screw away from the movable block, and a rotating block is installed at the end of the lead screw close to the movable block, with the rotating block engaging inside the movable block.

[0009] Preferably, the upper surface of the fixed block is provided with a groove, and a slider is movably installed inside the groove. The upper end of the slider is connected to the movable block. Guide rods are respectively installed at the front and rear ends inside the groove, and the rods of the guide rods are movably installed inside the slider.

[0010] Preferably, a friction block is movably installed inside the movable block at one end close to the brake ring. The friction block is in contact with the friction plate. Several bolts are threadedly installed inside the movable block at one end close to the brake ring. The ends of the bolts away from the brake ring are in contact with the friction blocks.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) In this utility model, through the design of the deceleration mechanism, the user can rotate the turntable to drive the lead screw to rotate, thereby pushing the movable block closer to or away from the brake ring, so as to adjust the tightness of the fit between the friction plate and the brake ring. When the speed of the worktable increases due to the wire rod or wire, the friction between the friction plate and the brake ring can be increased, and the speed of the worktable can be effectively reduced by the friction resistance. Conversely, the friction can be reduced to meet the low speed requirements. This adjustable deceleration method can accurately control the rotation speed of the worktable, avoid the problem of unstable wire rod or wire conveying due to excessive speed, reduce quality defects such as uneven material stretching and bending deformation, and ensure the continuity of subsequent processing procedures.

[0013] (2) The groove on the surface of the workbench in this utility model is combined with the threaded rod and nut. The fixed position can be adjusted according to the specifications of the wire rod or wire, which enhances the adaptability to materials of different sizes. The friction block and bolt design inside the movable block can adjust the pressure of the friction block on the friction plate through the bolt, indirectly compensating for the wear of the friction plate and extending its service life. In addition, the support frame strengthens the fixed block, which improves the overall structural strength of the deceleration mechanism and ensures the stability in long-term use. It is suitable for bolt production needs under different working conditions. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown in the figure, this utility model embodiment proposes a slow-speed feeding rack for a bolt forming machine, including a worktable 1. A transmission rod 2 is installed in the middle of the lower surface of the worktable 1. A base 4 is engaged with the lower end of the transmission rod 2. A reduction mechanism 3 is installed between the transmission rod 2 and the base 4. The reduction mechanism 3 includes a brake ring 301 and a fixing block 302. The brake ring 301 is installed on the lower surface of the transmission rod 2, and the upper end of the base 4 is engaged with the inside of the brake ring 301. A plane bearing 8 is installed inside the brake ring 301. The upper and lower ends of the plane bearing 8 are engaged with the transmission rod 2. The moving rod 2 and the base 4 are in contact with each other. The fixed block 302 is installed on the upper end of one side of the base 4. A support block 304 is installed on the upper surface of the fixed block 302 and on the side away from the brake ring 301. A lead screw 305 is installed inside the support block 304 through a threaded engagement. A movable block 310 is movably installed on the upper surface of the fixed block 302. The end of the lead screw 305 near the brake ring 301 is connected to the movable block 310. A friction plate 312 is installed on the side of the movable block 310 near the base 4. The friction plate 312 is in contact with the brake ring 301.

[0023] like Figures 4 to 6As shown, in another embodiment of this utility model, the upper surface of the workbench 1 is provided with several grooves 5, and threaded rods 6 are movably installed inside the grooves 5 respectively. Nuts 7 are respectively installed on the outer side of the rod body at the upper end of the workbench 1 by threads. A support frame 303 is installed between the lower surface of the fixing block 302 and the base 4. A turntable 306 is installed at the end of the lead screw 305 away from the movable block 310, and a rotating block 311 is installed at the end of the lead screw 305 close to the movable block 310. The rotating block 311 is engaged inside the movable block 310. The upper surface of the fixing block 302 is provided with a sliding groove 307. The slide 307 has a movable slider 309 inside, the upper end of which is connected to the movable block 310. The slide 307 has guide rods 308 installed at both the front and rear ends. The rods of the guide rods 308 are movably installed inside the slide 309. The movable block 310 has a friction block 313 movably installed at the end closest to the brake ring 301 inside. The friction block 313 is in contact with the friction plate 312. The movable block 310 has several bolts 314 installed inside the end closest to the brake ring 301 through threads. The ends of the bolts 314 away from the brake ring 301 are in contact with the friction block 313.

[0024] The wire rod or coil is placed on the worktable 1. The threaded rod 6 in the groove 5 is adjusted and tightened with the nut 7 to achieve stable support for wire rods or coils of different specifications. When the wire rod or coil is drawn, its tension drives the worktable 1 to rotate. The worktable 1 transmits the rotational force to the brake ring 301 via the transmission rod 2, causing the brake ring 301 to rotate synchronously with the transmission rod 2. The plane bearing 8 acts as a lubricant between the transmission rod 2 and the base 4, reducing frictional resistance during relative rotation. Then, when it is necessary to reduce the rotational speed of the worktable 1... When the user rotates the turntable 306, the lead screw 305 rotates within the support block 304. The lead screw 305 pushes the movable block 310 along the guide rod 308 in the slide groove 307 towards the brake ring 301 via the rotating block 311. This causes the friction plate 312 on the movable block 310 to come into contact with the brake ring 301. The friction reduces the rotational speed of the brake ring 301 and the transmission rod 2, thereby slowing down the worktable 1. Then, rotating the turntable 306 in the opposite direction can reduce the tightness of the contact between the friction plate 312 and the brake ring 301, thus reducing the deceleration effect.

[0025] If the friction plate 312 becomes worn, the friction block 313 can be separated from the friction plate 312 by turning the bolt 314 on the movable block 310, and then the user can replace the friction plate 312.

[0026] The combination of turntable 306 and lead screw 305 enables precise control of the tightness of the fit between friction plate 312 and brake ring 301. Users can flexibly adjust the deceleration force according to the actual speed requirements to avoid problems such as material stretching and deformation and equipment jamming caused by excessive speed.

[0027] The working principle of the slow-speed feeding rack of the bolt forming machine:

[0028] In use, first place the wire rod or wire on the worktable 1, adjust the threaded rod 6 in the groove 5, and tighten the nut 7 to achieve stable support for wire rods or wires of different specifications. Then, when the wire rod or wire is drawn, its tension drives the worktable 1 to rotate. The worktable 1 transmits the rotational force to the brake ring 301 through the transmission rod 2, causing the brake ring 301 to rotate synchronously with the transmission rod 2. Then, the plane bearing 8 acts as a lubricant between the transmission rod 2 and the base 4, reducing the frictional resistance when the two rotate relative to each other. Then, when it is necessary to lower the worktable... At speed 1, the user rotates the turntable 306, causing the lead screw 305 to rotate within the support block 304. The lead screw 305 pushes the movable block 310 along the guide rod 308 in the slide groove 307 towards the brake ring 301 via the rotating block 311, so that the friction plate 312 on the movable block 310 fits against the brake ring 301. The friction reduces the speed of the brake ring 301 and the transmission rod 2, thereby reducing the speed of the worktable 1. Then, rotating the turntable 306 in the opposite direction can reduce the tightness of the fit between the friction plate 312 and the brake ring 301, reducing the speed reduction effect.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
