Description

Technical Field

[0001] This utility model belongs to the field of steel bracket processing technology, and more specifically, it relates to a clamping device for cold bending processing of steel brackets. Background Technology

[0002] In the cold bending process of steel profile supports, the rolling mill is the core equipment for achieving continuous arc / large curvature forming. It is mainly used for batch processing of long-length steel profile supports with fixed curvature (such as tunnel arch supports, circular pipe supports, and curved curtain wall supports). Its core principle is to apply continuous and gradual extrusion force to the steel profile through multiple sets of rollers arranged along a specific trajectory, so that the steel profile gradually undergoes plastic deformation and finally forms a curved shape consistent with the roller trajectory. Existing rolling mills generally consist of a frame, a roller system, a drive system, and a clamping and guiding system.

[0003] Existing application number: CN202020695185.3, this utility model discloses a cold bending forming equipment for photovoltaic brackets, relating to the technical field of cold bending forming equipment for steel profiles. It includes a machine base, on which a cooling device and multiple forming devices arranged in a row are installed. Each forming device includes a lower forming roller and an upper forming roller. The cooling device includes an upper cooling pipe and a lower cooling pipe. The upper cooling pipe has multiple upper cooling inlets, and the lower cooling pipe has multiple lower cooling inlets. A cooling box is detachably connected to one end of the upper cooling pipe, and a water tank is fixed inside the cooling box. An ultrasonic oscillator is fixed inside the water tank, and a cold air duct is fixed to one side of the cooling box. A water outlet hose connects the water tank and the lower cooling pipe. Through the ultrasonic oscillator and the cold air duct, cold air and water mist work together to rapidly cool the upper forming roller; the water tank and water outlet hose also allow for rapid cooling of the lower forming roller. This utility model can cool the forming rollers while performing cold bending forming of steel profiles, extending the service life of the forming rollers.

[0004] Based on the above, the clamping guide wheel assembly at the feed position of the rolling mill has a significant "one-to-one adaptation" limitation. It cannot achieve universal adaptation for steel sections with different thicknesses or widths. Each time a cold bending process of one type of steel is completed and the process is switched to another, the original roller assembly must be completely disassembled from the equipment and then the roller assembly adapted to the new type of steel must be repositioned and installed. The entire disassembly, replacement and calibration process is cumbersome and time-consuming. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a clamping device for cold bending of steel profiles, which solves the significant "one-to-one adaptation" limitation of existing clamping guide wheel assemblies at the feed position of rolling mills. These assemblies cannot achieve universal adaptation for steel profiles of different cross-sectional thicknesses or widths. Furthermore, when switching from one type of steel profile to another after cold bending, the original roller assembly must be completely disassembled from the equipment, and then a new roller assembly adapted to the new steel must be repositioned and installed. This entire disassembly, replacement, and calibration process is cumbersome and time-consuming.

[0006] The purpose and effect of this utility model of a clamping device for cold bending of steel brackets are achieved by the following specific technical means: A clamping device for cold bending of steel profile supports includes a rolling mill body, a fixed box, adjusting cavities, a clamping motor, adjusting sleeves, clamping guide wheels, a pressing assembly, and a clamping spacing adjusting assembly. The fixed box is fixedly connected to the top of the rolling mill body. Two adjusting cavities are provided, each located inside the fixed box. The clamping motor is fixedly connected to the front of the fixed box. Four adjusting sleeves are provided, each located inside one of the two adjusting cavities. Four clamping guide wheels are provided, each located above one of the four adjusting sleeves. Four sets of pressing assemblies are provided, each located above one of the four adjusting sleeves. The clamping spacing adjusting assembly is located inside the fixed box.

[0007] Furthermore, the clamping assembly includes: a fixed guide post and a sliding disc; the fixed guide post is fixedly connected above the adjusting sleeve; the sliding disc is slidably connected to the outside of the fixed guide post, and the top of the clamping guide wheel is rotatably connected inside the sliding disc.

[0008] Furthermore, the clamping assembly also includes: an adjusting screw and an adjusting knob; the bottom of the adjusting screw is rotatably connected to the top of the adjusting sleeve, and the adjusting screw is threadedly connected to the sliding disc; the adjusting knob is coaxially fixedly connected to the top of the adjusting screw.

[0009] Furthermore, the clamping spacing adjustment assembly includes: a connecting shaft, a driving worm, and a driving worm wheel; the connecting shaft is coaxially fixedly connected to the end of the clamping motor shaft; the driving worm is coaxially fixedly connected to the rear end of the connecting shaft; the driving worm wheel is rotatably connected inside the fixed box, and the driving worm wheel meshes with the driving worm.

[0010] Furthermore, the clamping gap adjustment assembly also includes: a transmission gear and a transmission rack; the transmission gear is coaxially and fixedly connected to the right side of the drive worm gear; two transmission racks are provided, and the two transmission racks are slidably connected inside the fixed box, and the two transmission racks mesh with the transmission gear respectively.

[0011] Furthermore, the clamping spacing adjustment assembly also includes: connecting sliders and transmission connectors; four connecting sliders are provided, each of which is slidably connected to the bottom of the fixed box, and each of which is fixedly connected to the two front adjusting sleeves and the two rear adjusting sleeves respectively; two transmission connectors are provided, with their left and right ends fixedly connected to the inner sides of the two front connecting sliders and the two rear connecting sliders respectively, and their tops fixedly connected to the outer ends of the two transmission racks respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, when the thickness of the processed steel plate changes, simply turn the adjustment knob to drive the sliding plate to slide up and down, thereby stably clamping steel plates of different thicknesses between the sliding plate and the adjustment sleeve. At the same time, the clamping guide wheel can rotate synchronously with the plate conveying, greatly reducing the frictional resistance between the plate and the guide wheel, ensuring a smooth and labor-saving steel plate conveying process, which simplifies the thickness adaptation operation and ensures the stability of the feeding.

[0013] Secondly, when the width of the processed steel plate changes, simply start the clamping motor. Through the clamping spacing adjustment component, the front and rear adjustment sleeves and clamping guide wheels can be driven to move synchronously inward or outward in the two adjustment chambers, quickly adjusting the clamping spacing to fit the size of the new width plate. The entire adjustment process is convenient and saves the cumbersome steps and time of traditional type change.

[0014] This invention allows the sliding disc to slide up and down by rotating the adjustment knob to stably clamp plates of different thicknesses. The clamping gap adjustment component can drive the adjustment sleeve and clamping guide wheel to move synchronously to adjust the gap, adapting to the feeding clamping guidance requirements of different specifications of steel plates in the cold bending process. It eliminates the cumbersome steps and time consumption of traditional shape change, effectively reduces the downtime adjustment time of the rolling mill, and significantly improves the switching efficiency of processing steel plates of multiple widths.

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a clamping device for cold bending of steel brackets, including a rolling mill body 1, a fixed box 2, an adjusting cavity 201, a clamping motor 3, an adjusting sleeve 4, clamping guide wheels 6, and a pressing assembly; the fixed box 2 is fixedly connected above the rolling mill body 1; two adjusting cavities 201 are provided, and the two adjusting cavities 201 are respectively opened inside the fixed box 2; the clamping motor 3 is fixedly connected in front of the fixed box 2; four adjusting sleeves 4 are provided, and the four adjusting sleeves 4 are respectively arranged inside the two adjusting cavities 201; four clamping guide wheels 6 are provided, and the four clamping guide wheels 6 are respectively arranged above the four adjusting sleeves 4; four sets of pressing assemblies are provided, and the four sets of pressing assemblies are respectively arranged above the four adjusting sleeves 4.

[0023] The clamping assembly includes a fixed guide post 5 and a sliding disk 7. The fixed guide post 5 is fixedly connected above the adjusting sleeve 4. The sliding disk 7 is slidably connected to the outside of the fixed guide post 5, and the top of the clamping guide wheel 6 is rotatably connected to the inside of the sliding disk 7.

[0024] The clamping assembly also includes: an adjusting screw 8 and an adjusting knob 801; the bottom of the adjusting screw 8 is rotatably connected to the top of the adjusting sleeve 4, and the adjusting screw 8 is threadedly connected to the sliding disc 7; the adjusting knob 801 is coaxially fixedly connected to the top of the adjusting screw 8.

[0025] The specific usage and function of this embodiment are as follows: When in use, if the thickness of the steel plate to be processed changes, the adjustment knob 801 can be rotated. Under the sliding cooperation guidance of the fixed guide column 5 and the sliding disk 7, the adjusting screw 8 will drive the sliding disk 7 to slide up and down through the threaded transmission mechanism formed together with the sliding disk 7, thereby clamping the steel plate between the lower part of the sliding disk 7 and the upper part of the adjusting sleeve 4. At the same time, the top of the clamping guide wheel 6 is rotatably connected to the inside of the sliding disk 7. When the steel plate is conveyed, the plate contacts the clamping guide wheel 6, which will drive the clamping guide wheel 6 to rotate, reducing the friction between the plate and the clamping guide wheel 6, making the conveying process of the steel plate smoother and less labor-intensive. Example 2

[0026] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes a clamping spacing adjustment component, which is disposed inside the fixing box 2.

[0027] The clamping spacing adjustment assembly includes: a connecting shaft 301, a driving worm 302, and a driving worm wheel 9; the connecting shaft 301 is coaxially fixedly connected to the end of the shaft of the clamping motor 3; the driving worm 302 is coaxially fixedly connected to the rear end of the connecting shaft 301; the driving worm wheel 9 is rotatably connected inside the fixed box 2, and the driving worm wheel 9 meshes with the driving worm 302.

[0028] The clamping gap adjustment assembly also includes a transmission gear 901 and a transmission rack 10. The transmission gear 901 is coaxially fixedly connected to the right side of the drive worm gear 9. Two transmission racks 10 are provided, and the two transmission racks 10 are slidably connected inside the fixed box 2, and the two transmission racks 10 are respectively meshed with the transmission gear 901.

[0030] The specific usage and function of this embodiment: When the width of the steel plate to be processed changes, the clamping motor 3 is started. The rotating shaft of the clamping motor 3 rotates in both directions, driving the connecting shaft 301 to rotate. This drives the transmission gear 901 to rotate through the worm gear 302 and the worm wheel 9 meshing worm gear transmission mechanism. The transmission gear 901 drives the two transmission connecting parts 12 to move inward or outward simultaneously through the gear and rack transmission mechanism meshing with the two transmission racks 10. The two transmission connecting parts 12 drive the two sets of adjusting sleeves 4 to move inward or outward simultaneously inside the two adjusting cavities 201 through the four connecting sliders 11. This adjusts the distance between the two sets of clamping guide wheels 6 to a width suitable for clamping the steel plate to be processed, saving the time of changing the clamping guide wheels 6.
