Description

Technical Field

[0001] The utility model relates to the technical field of steel plate straightening, in particular to a plate straightening device used for steel material processing. Background Art

[0002] Steel is widely used and comes in many varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. Steel is a material of a certain shape, size and performance made of ingots, billets or steel through pressure processing. In steel processing, straightening devices are needed to correct the shape defects of steel.

[0003] The steel straightening device generally uses two rows of squeezing rollers to squeeze the steel plate to achieve the straightening effect. Since the width specifications of steel plates are of various types, the current steel plate straightening devices often design the squeezing rollers for straightening to be longer to adapt to plates of different specifications. However, the longer squeezing rollers will also cause the middle part to bend, and the straightening effect cannot be guaranteed. Utility Model Content

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a plate straightening device for steel processing, including a rectangular device frame with open ends and multiple supporting mechanisms;

[0006] The top ends of the two side surfaces of the device frame are fixedly connected with fixed seats, the bottom ends of the two fixed seats are vertically fixedly connected with tension springs, the bottom ends of the two tension springs are fixedly connected with sliders vertically slidably connected to the side surfaces of the device frame, the outer surfaces of the two sliders are transversely penetrated with through holes, the interiors of the two through holes are transversely connected with rotating shafts, the two side surfaces of the device frame are transversely penetrated with through grooves arranged along their height direction, the inner ends of the two rotating shafts extend to the interior of the device frame through the two through grooves respectively, and an upper pressure roller is transversely fixedly connected between the two rotating shafts.

[0007] Furthermore, a mounting hole is vertically penetrated through the top of the device frame, and hydraulic rods are vertically fixedly connected inside the plurality of mounting holes, and the plurality of supporting mechanisms are respectively arranged at the bottom ends of the plurality of hydraulic rods.

[0008] Furthermore, the structures of the plurality of support mechanisms are the same, wherein one of the support mechanisms comprises a device block fixedly connected to the bottom end of the hydraulic rod, and the lower surface contour of the device block is adapted to the cross-sectional contour of the upper pressure roller.

[0009] Furthermore, an arc groove matching the profile of the upper pressing roller is formed at the bottom end of the device block, and a plurality of rollers are rotatably connected to the inside of the arc groove in a transverse manner.

[0010] Furthermore, the plurality of rollers are evenly spaced apart along the circumferential direction of the cross section of the arc-shaped groove.

[0011] Furthermore, a lower pressure roller is rotatably connected to the bottom end of the device frame, and a plurality of supporting pads are fixedly connected to the bottom end of the device frame.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the plate straightening device used for steel processing is provided with multiple supporting mechanisms. When adjusting the distance between the two squeezing rollers, the device drives the multiple supporting mechanisms to move through multiple hydraulic rods, and then drives the upper pressure roller to move downward through the multiple supporting mechanisms to adjust the distance between the two squeezing rollers.
