Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel processing equipment, in particular to a coiling device. BACKGROUND

[0002] The steel coiling device is a series of mechanical equipment for coiling steel into a roll or subsequent processing of the steel roll, and its performance and process level directly affect the quality and efficiency of steel processing.

[0003] In actual steel coiling production process, the coiling treatment of some short-length and small-width steel materials is often involved. Since the length of such steel materials is very short, the traditional steel coiling device is difficult to effectively bend them. In the prior art, enterprises mostly use manual bending to process these short-size steel materials, and then weld them.

[0004] However, this manual operation method has many serious defects. On the one hand, manual bending cannot guarantee the consistency and accuracy of the bending radius. Due to individual differences of the operators and uncontrollable factors in the operation process, the bending radius deviates greatly from the radius of the welded equipment. Such deviation will cause a large stress concentration phenomenon at the welding point, seriously affecting the use quality of the product. CONTENT OF THE INVENTION

[0005] In order to improve the accuracy of steel coiling, the present application provides a coiling device.

[0006] The coiling device provided by the present application adopts the following technical scheme:

[0007] A coiling device, comprising a fixed seat in the shape of a cylinder and a plurality of coiling rollers with different diameters distributed in the circumferential direction of the fixed seat, the diameters of the coiling rollers being matched with steel rolls of different size specifications, and each coiling roller being arranged perpendicular to the axial direction of the fixed seat, and each coiling roller being arranged in parallel with a fixed arm on one side, the fixed arm and the coiling roller forming a gap for inserting the end of a short steel material.

[0008] By adopting the above technical scheme, the operator can insert one end of the short steel material into the gap between the fixed arm and the coiling roller, and then knock the short steel material with a tool to make it tightly fit the surface of the coiling roller, thereby completing the accurate coiling forming. In this design, the plurality of coiling rollers are uniformly arranged in the circumferential direction, which can match the processing needs of steel rolls of different specifications, thereby expanding the application range of the device and effectively improving the work efficiency. At the same time, compared with the traditional manual bending method, this method greatly reduces the error caused by human factors, ensures the consistency of the bending radius, and thus significantly improves the quality stability of the product processing.

[0009] Optionally, a guide rod is arranged on one side of the fixed arm towards the crimping roller, a guide block is arranged on the bottom of the crimping roller for the guide rod to slide through, and an adjusting assembly is arranged between the fixed arm and the corresponding crimping roller to adjust the gap distance, the adjusting assembly comprising an adjusting screw rotatably arranged on the fixed arm and a fixed nut arranged on the bottom of the crimping roller, the adjusting screw being parallel to the guide rod and arranged on both sides of the bottom of the fixed arm in the length direction of the fixed arm, one end of the adjusting screw near the crimping roller being rotatably threaded through the fixed nut, and the other end of the adjusting screw away from the fixed nut extending out of the fixed arm, and a knob being arranged on the end of the fixed arm extending out.

[0010] By adopting the above technical scheme, when it is necessary to adjust the gap between the fixed arm and the crimping roller according to the specifications of the short steel material, the relative position of the fixed arm and the crimping roller can be flexibly changed by rotating the adjusting screw. The guide rod and the guide block cooperate with each other to ensure the stability and accuracy of the movement of the fixed arm, thereby enhancing the reliability of the relative position of the two. In addition, the design of the adjusting screw supports manual stepless adjustment, which can meet the accurate fitting requirements of different specifications of short steel materials, so that the end of the short steel material is more stably embedded in the gap. This design not only significantly improves the stability and precision of the crimping operation, but also maximally reduces the errors that may be introduced by manual operation, thereby improving the uniformity of the products and the overall processing efficiency.

[0011] Optionally, the crimping roller is detachably arranged between the fixed seat, a assembly groove is coaxially arranged on the top of the fixed seat, a T-shaped insertion block is arranged on the end of each crimping roller towards the fixed seat, an insertion slot is arranged on the fixed seat corresponding to each insertion block and communicating with the assembly groove, the top of the insertion slot extends to the top wall of the fixed seat, and a pressing block is threadedly and rotatably connected in the assembly groove, the pressing block pressing the insertion block against the inner bottom of the assembly groove.

[0012] By adopting the above technical scheme, with the cooperation of the insertion block and the insertion slot, the installation and replacement of the crimping roller can be quickly realized, further increasing the application range of different specifications of steel coil processing requirements. At the same time, the pressing block applies pressure to the insertion block and firmly presses it against the inner bottom of the assembly groove, improving the stability of the structure during crimping, effectively reducing the loosening of the crimping roller caused by vibration or other external factors, thereby improving the safety and reliability of the crimping operation.

[0013] Optionally, a lifting pipe is arranged at the top center of the pressing block for easy rotation and lifting.

[0014] By adopting the technical scheme, the lifting pipe provides a convenient operation position for the pressing block, so that the operator can easily exert force on the pressing block with external tools, thereby efficiently realizing the locking or unlocking operation of the pressing block in the assembly groove. In addition, when the entire coiling device needs to be transferred, the device can be conveniently and quickly carried as a whole by inserting the cross rod into the lifting pipe, thereby greatly improving the work efficiency and operation convenience.

[0015] Optionally, an inner bottom of the assembly groove is annularly provided with a ring groove for inserting the insertion block, and a side wall of the ring groove near the fixed seat is obliquely arranged. The bottom surface of the insertion block is obliquely arranged in cooperation with the inclined side wall of the ring groove. When the insertion block is inserted into the ring groove, the top wall of the insertion block is arranged flush with the bottom wall of the assembly groove.

[0016] By adopting the technical scheme, the design of the ring groove facilitates the insertion and guidance of the insertion block, and the obliquely arranged side wall can reduce the frictional resistance in the insertion process, thereby improving the smoothness of the insertion block into the assembly groove. Meanwhile, the cooperation structure of the insertion block and the ring groove ensures the stability of the contact surface therebetween, thereby reducing the installation error caused by positional deviation. Finally, when the insertion block is completely inserted into the ring groove, the top wall thereof is flush with the bottom wall of the assembly groove, which not only improves the compactness of the overall structure, but also provides a flat basis for the subsequent pressing operation of the pressing block, thereby improving the overall reliability and safety of the device.

[0017] Optionally, the fixed arm is provided with a plurality of anti-skid protrusions on the side facing the corresponding coiling roller.

[0018] By adopting the technical scheme, the plurality of anti-skid protrusions provided on the side of the fixed arm facing the coiling roller can increase the friction between the fixed arm and the short steel material, thereby effectively reducing the possibility of slippage of the short steel material during clamping, thereby improving the stability and reliability of the coiling operation.

[0019] Optionally, the bottom of the fixed seat is provided with a turntable, and the turntable comprises a bottom disc, a supporting shaft and a tray coaxially arranged. The tray is used to lift the fixed seat and is located above the bottom disc. The supporting shaft is rotatably connected to the bottom disc and the tray through bearings.

[0020] By adopting the technical scheme, after the turntable structure is additionally arranged at the bottom of the fixed seat, the entire coiling device can be flexibly rotated around the supporting shaft, thereby conveniently adjusting the working angle of each coiling roller. This design significantly improves the operation flexibility of the device, and different diameters of coiling rollers can be quickly switched to adapt to steel processing tasks of various sizes without moving the entire device. Especially in a limited space operation environment, the design avoids frequent manual carrying and rotating of the fixed seat, greatly reduces the labor intensity of the operator, and effectively improves the work efficiency.

[0021] Optionally, the rotating disc is further provided with a pin rod for locking the rotating disc, the top wall of the fixing seat extending out of the tray is circumferentially distributed with a plurality of vertically penetrating through holes, and the top wall of the base disc is provided with a positioning hole corresponding to each through hole, the pin rod being inserted from the through hole vertically interfacing with the positioning hole and having a bottom end inserted into the positioning hole.

[0022] By adopting the above technical scheme, the design of the pin rod can effectively prevent the rotating disc from accidental displacement when it is not required to rotate, ensuring that the coiling device remains in a stable state during operation. Meanwhile, by providing a plurality of through holes on the tray and cooperating with the positioning holes on the base disc, the angle of the fixing seat can be flexibly adjusted and locked at any desired position, improving the convenience and adaptability of the device in use. This design significantly improves the operation precision and safety of the coiling device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The operator can insert one end of the short steel into the gap between the fixing arm and the coiling roller, then knock the short steel with a tool to make it closely fit the surface of the coiling roller, thereby completing the precise coiling forming. In this design, a plurality of coiling rollers are evenly arranged in the circumferential direction, which can match the processing needs of different specifications of steel coils, thereby expanding the application range of the device and effectively improving the work efficiency. At the same time, compared with the traditional manual bending method, this method greatly reduces the errors caused by human factors, ensures the consistency of the bending radius, and thus significantly improves the quality stability of product processing;

[0025] 2. When it is necessary to adjust the gap between the fixing arm and the coiling roller according to the specifications of the short steel, the relative position of the fixing arm and the coiling roller can be flexibly changed by rotating the adjusting screw. The guide rod and the guide block cooperate with each other to ensure the stability and precision of the fixing arm during movement, thereby enhancing the reliability of the relative position of the two. In addition, the design of the adjusting screw supports manual stepless adjustment, which can meet the precise adaptation needs of different specifications of short steel, making the end of the short steel more stably embedded in the gap. This design not only significantly improves the stability and precision of the coiling operation, but also maximally reduces the errors that may be introduced by manual operation, thereby improving the uniformity and overall processing efficiency of the products;

[0026] 3. By means of the cooperation structure of the insertion block and the insertion slot, the installation and replacement of the coiling roller can be quickly realized, further increasing the application range of different specifications of steel coil processing needs. At the same time, the pressing block applies pressure to the insertion block and firmly presses it against the bottom of the assembly slot, improving the stability of the structure during coiling and effectively reducing the loosening of the coiling roller caused by vibration or other external factors, thereby improving the safety and reliability of the coiling operation.
