Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The quantity of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0027] Next, with reference to several representative embodiments of the present utility model, the principles and spirits of the present utility model will be elaborated in detail.

[0028] A pinch device for producing ribbed steel bars provided by the present utility model, as Figures 1 to 3As shown in the figure, it includes a pinch-feed structure 1. The pinch-feed structure 1 includes a mounting frame 11, a guide tube 14, and a pinch-feed assembly. The guide tube 14 corresponds to the pinch-feed assembly. The pinch-feed assembly includes a driving wheel 12 and a driven wheel 13 for clamping steel bars. The mounting frame 11 includes a fixed seat 111, a sliding seat 112, and a guide rod 113. A first bearing 1111 is provided on the fixed seat 111, and the driving wheel 12 is rotationally engaged with the first bearing 1111. A second bearing 1121 is provided on the sliding seat 112, and the driven wheel 13 is rotationally engaged with the second bearing 1121. The sliding seat 112 is slidably connected to the guide rod 113. An elevating adjustment assembly 2 for adjusting the sliding of the sliding seat 112 is provided on the mounting frame 11;

[0029] The elevating adjustment assembly 2 includes a movable plate 21, an adjustment bolt 22, and an elastic member 23. The elastic member 23 is abutted and connected between the movable plate 21 and the sliding seat 112. The adjustment bolt 22 penetrates through the mounting frame 11, and the adjustment bolt 22 is abutted and cooperated with the movable plate 21 so that the adjustment bolt 22 and the elastic member 23 act together to realize the elevating adjustment of the movable plate 21.

[0030] In this embodiment, the pinch-feed device is mainly composed of components such as a mounting frame 11, a driving wheel 12, a driven wheel 13, and a guide tube 14. The mounting frame 11 is further subdivided into a fixed seat 111, a sliding seat 112, and a guide rod 113, which jointly support and guide the movement of the pinch-feed structure 1. The driving wheel 12 is rotationally engaged with the fixed seat 111 through the first bearing 1111 and is driven to rotate by an external power source. The driven wheel 13 is rotationally engaged with the sliding seat 112 through the second bearing 1121, and its position can be adjusted as needed. Under the action of the elevating adjustment assembly 2, the sliding seat 112 slides along the guide rod 113 to realize the precise adjustment of the position of the driven wheel 13. When the ribbed steel bar enters the pinch-feed device, the driving wheel 12 and the driven wheel 13 act together to clamp and convey the steel bar forward. By adjusting the position of the driven wheel 13, steel bars of different diameters or thicknesses can be adapted to ensure the stability and reliability of the pinch-feed process.

[0031] In this embodiment, the mounting frame 11 is set as a frame structure. The adjustment bolt 22 penetrates through the mounting frame 11 and is threadedly connected to the mounting frame 11. A fastening nut 24 is provided on the outer wall of the adjustment bolt 22. By turning the fastening nut 24, the position stability of the adjustment bolt 22 after adjusting the elevation of the movable plate 21 can be further ensured. In other embodiments, the driving mode of the adjustment bolt 22 can be realized in various forms such as manual, electric, and pneumatic.

[0032] In this embodiment, there are two groups of guide rods 113. The two groups of guide rods 113 are respectively located on both sides of the sliding seat 112, and the guide rod 113 penetrates through the sliding seat 112, ensuring the smooth movement of the sliding seat 112 in the vertical direction, reducing the friction and resistance caused by deviation or inclination, and effectively improving the stability and accuracy of the pinch-feed device.

[0033] In this embodiment, the elastic member 23 is a spring. The elastic member 23 is in an annular structure and is sleeved on the outer wall of the guide rod 113. Both ends of the elastic member 23 are fixedly connected to the movable plate 21 and the sliding seat 112 respectively. When the adjusting bolt 22 applies a lifting force to the sliding seat 112 through the movable plate 21, the elastic member 23 can absorb part of the impact and vibration, making the movement of the sliding seat 112 smoother and more controllable. At the same time, the elastic member 23 also has a certain self-adaptive ability and can automatically adjust its compression degree according to the load size, so as to maintain an appropriate clamping force between the driven wheel 13 and the driving wheel 12.

[0034] In this embodiment, grooves 131 for fitting with steel bars are provided on both the driving wheel 12 and the driven wheel 13, so that ribbed steel bars can be clamped more tightly. When the steel bar enters the device, its surface (especially the rib part) will be embedded into the grooves 131, thus achieving a more stable clamping and conveying effect.

[0035] In this embodiment, the driving wheel 12 and the driven wheel 13 are parallel to each other, and the grooves 131 on the two of them correspond to each other, ensuring that the driving wheel 12 and the driven wheel 13 can maintain the same traveling direction and speed during the clamping and conveying process. At the same time, it can effectively enhance the stability and accuracy of the steel bar clamping and conveying, and avoid the steel bar from shifting or twisting during the clamping and conveying process.

[0036] In this embodiment, the guide tube 14 corresponds to the groove 131. A support frame is provided on the mounting frame 1, and the guide tube 14 is fixedly connected to the support frame. The steel bar enters the grooves 131 on the driving wheel 12 and the driven wheel 13 from the guide tube 14, which can further enhance the stability and accuracy of the steel bar clamping and conveying, and avoid the steel bar from shifting or twisting during the clamping and conveying process.

[0037] It should be noted that the driving wheel 12 is driven to rotate by an external power source. After the groove 131 on it is engaged with the steel bar, the power is transmitted to the steel bar through friction, while the driven wheel 13 rotates passively as the steel bar moves, and its groove 131 also plays a role in clamping and guiding.

[0038] In this embodiment, there are two sets of clamping and conveying components, which can make the stability of the steel bar conveyed along the clamping and conveying components higher. In this embodiment, there are two sets of guide tubes 14. One set of guide tubes 14 is located between the two sets of clamping and conveying components, and the other set of guide tubes is located on the side of the clamping and conveying components facing the steel bar output direction. In other embodiments, the clamping and conveying components and the guide tube 14 can be set in various forms such as one set and multiple sets respectively, and the guide tube 14 can also be arranged on the side of the clamping and conveying components facing the steel bar input direction.

[0039] In this embodiment, two sets of the driving wheels 12 are linked and connected with a driving mechanism 3 for driving the driving wheels 12 to rotate. The driving mechanism 3 includes a driving motor 31 and a transmission shaft 32. The driving motor 31 is linked and connected with the transmission shaft 32. There are two sets of the transmission shafts 32, and the two sets of the transmission shafts 32 are respectively linked and connected with the two sets of the driving wheels 12. A transmission wheel 33 is sleeved on the outer wall of the transmission shaft 32, and a transmission belt 34 is sleeved on the transmission wheel 33.

[0040] In this embodiment, the driving motor 31 serves as a power source and transmits power to the driving wheels 12 through the transmission shaft 32. In order to achieve synchronous driving of the two sets of driving wheels 12, the driving motor 31 is linked and connected with one of the transmission shafts 32, and this transmission shaft 32 then transmits power to the other transmission shaft 32 through the linkage cooperation of the transmission wheel 33 and the transmission belt 34. When the transmission shaft 32 rotates, the driving wheels 12 will also rotate accordingly. When the steel bar enters the pinch feeding device, the grooves 131 on the two sets of driving wheels 12 and the driven wheels 13 will jointly clamp the steel bar. As the driving wheels 12 rotate, the steel bar will be conveyed forward. Since the two sets of driving wheels 12 and the driven wheels 13 all work synchronously, the steel bar can maintain a stable traveling direction and speed throughout the pinch feeding process.

[0041] In this embodiment, the driving mechanism 3 includes a frame box body 35, which bears various forces and torques generated during the transmission process and protects the internal transmission components from the influence of the external environment. The frame box body 35 is fixedly connected with the mounting frame 11. A linkage wheel 321 is arranged on one of the transmission shafts 32, and a linkage belt 322 is sleeved on the outer wall of the linkage wheel 321 and the outer wall of the driving end of the driving motor 31. In this embodiment, when the driving motor 31 is started, its driving end drives the linkage wheel 321 to rotate through the linkage belt 322. Since the linkage wheel 321 is coaxially installed with one of the transmission shafts 32, this transmission shaft 32 will also rotate accordingly. Through the linkage cooperation of the transmission wheel 33 and the transmission belt 34, synchronous rotation of the two sets of transmission shafts 32 is achieved, and further synchronous rotation of the two sets of driving wheels 12 is achieved.

[0042] In this embodiment, a plurality of bearing seats 351 are arranged on the side wall of the frame box body 35, and the two sets of the transmission shafts 32 both penetrate through the bearing seats 351, which are used to support the transmission shafts 32 and reduce friction and wear during their rotation.

[0043] In this embodiment, the guide rod 113 is perpendicular to the transmission shaft 32, which can make more effective use of space and enhance the stability of the device in three-dimensional space.

[0044] A pinch roll device for producing ribbed steel bars provided by the present utility model can, through the adjustment function of the lifting adjustment assembly 2, adapt to ribbed steel bars of different diameters or thicknesses, thereby effectively improving the versatility and flexibility of the device. Moreover, the device has a simple structure, low manufacturing cost, simple operation, and low operation time cost. The close cooperation between the driving wheel 12 and the driven wheel 13, as well as the smooth sliding of the sliding seat 112 along the guide rod 113, ensure the stability and reliability of the steel bar during the pinching and feeding process, reduce quality problems caused by vibration or slipping, and the stable pinching and feeding process helps to maintain the continuity and high efficiency of the production line, improving production efficiency and product quality.
