Description

Technical Field

[0001] This utility model relates to the field of strip steel torsion guide groove technology, and in particular to a strip steel torsion guide groove. Background Technology

[0002] On hot-rolled strip steel production lines, in order to achieve continuous rolling, coiling, or specific processing of strip steel, torsion guide grooves are usually used to torsion the strip steel to ensure that the strip steel is torsion in the correct direction and angle during the rolling process, thereby ensuring the continuity of production and product quality.

[0003] According to the Chinese patent "A Segmented Torsional Guide Groove" authorized announcement number "CN212525459U", the distance between the fixed guide wheel and the moving guide wheel can be adjusted by the cooperation of the mounting block, rotating part, screw and handwheel. This makes the fixed guide wheel and the moving guide wheel suitable for various specifications of strip steel. When changing the strip steel model, only the arc section needs to be replaced.

[0004] In the aforementioned application, the fixed guide wheel and the moving guide wheel tend to twist the moving strip steel, which can easily generate a large torque force that is transmitted to the screw surface. This can easily cause the screw to shift, affecting the stability of the distance between the fixed guide wheel and the moving guide wheel, and thus affecting the torsion effect on the strip steel. Utility Model Content

[0005] Therefore, it is necessary to provide a strip torsion guide groove to address the problem that the torsion of the strip by the fixed guide wheel and the moving guide wheel can easily generate a large torque force that is transmitted to the screw surface, which can easily lead to screw displacement.

[0006] The device includes: an adjusting seat, wherein a fixed guide wheel is rotatably connected to the inner wall of the adjusting seat; and an anti-deviation mechanism, wherein the anti-deviation mechanism includes a protective sleeve fixedly connected to the top of the adjusting seat, a lead screw rotatably connected to the inner wall of the protective sleeve, a sliding frame threadedly connected to the surface of the lead screw, a movable guide wheel rotatably connected to the inner wall of the sliding frame, a toggle block fixedly connected to the surface of the lead screw, a positioning rod and a long rod slidably connected to the inner wall of the toggle block, the surface of the positioning rod engaging with the inner wall of the protective sleeve, and the surface of the long rod engaging with the inner wall of the positioning rod.

[0007] In one embodiment, a magnetic block is fixedly connected to the upper surface of the long rod, the actuating block is an iron-cobalt-vanadium alloy component, and the surface of the magnetic block is magnetically attracted to the inner wall of the actuating block.

[0008] In one embodiment, a rubber ball is fixedly connected to one side of the actuating block, and the surface of the rubber ball is engaged with the inner wall of the magnetic block.

[0009] In one embodiment, a spring is fixedly connected to the end of the long rod, and the top end of the spring is fixedly connected to the inner top wall of the actuating block.

[0010] In one embodiment, a limiting rod is fixedly connected to the surface of the positioning rod, and the surface of the limiting rod is slidably connected to the inner wall of the actuating block. The limiting rod restricts the movement range of the positioning rod, preventing it from detaching from the inner wall of the actuating block during movement.

[0011] In one embodiment, a transparent block is fixedly connected to the surface of the lead screw, one end of the transparent block contacts one end of the protective cylinder, and the surface of the positioning rod is slidably connected to the inner wall of the transparent block. The transparent block blocks the pre-drilled holes distributed in a ring on one end of the protective cylinder, preventing impurities from adhering to the pre-drilled holes and facilitating the smooth engagement of the positioning rod within the pre-drilled holes.

[0012] In one embodiment, two limiting blocks are fixedly connected to the surface of the moving frame, and the surfaces of the limiting blocks are slidably connected to the inner wall of the protective cylinder. The limiting blocks guide and limit the moving frame, preventing slippage during the linear movement of the frame driven by the lead screw.

[0013] Beneficial effects 1. By using a protective sleeve to enclose the surface of the lead screw, impurities are prevented from adhering to the surface of the lead screw, thereby reducing wear between the moving frame and the lead screw. This facilitates precise adjustment of the distance between the fixed guide wheel and the moving guide wheel. Through the cooperation of the actuating block, positioning rod and long rod, the lead screw is locked, thereby ensuring the stability of the moving guide wheel after the position is adjusted. This prevents the moving guide wheel from shifting during the twisting of the strip, thus ensuring the twisting effect of the strip. 2. By cooperating with the magnetic block and the rubber ball, the positioning rod is stably locked, which in turn improves the stability of the lead screw and thus improves the stability after the position of the moving guide wheel is adjusted.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is combined Figures 1-4 This invention describes the steel strip torsion guide groove.

[0019] In one embodiment, a steel strip torsion guide groove includes: an adjusting seat 100, with a fixed guide wheel 200 rotatably connected to the inner wall of the adjusting seat 100; and an anti-deviation mechanism 300, which includes a protective sleeve 301 fixedly connected to the top of the adjusting seat 100, a lead screw 304 rotatably connected to the inner wall of the protective sleeve 301, a shift bracket 302 threadedly connected to the surface of the lead screw 304, a moving guide wheel 303 rotatably connected to the inner wall of the shift bracket 302, a toggle block 305 fixedly connected to the surface of the lead screw 304, a positioning rod 306 and a long rod 307 slidably connected to the inner wall of the toggle block 305, the surface of the positioning rod 306 being engaged with the inner wall of the protective sleeve 301, and the surface of the long rod 307 being engaged with the inner wall of the positioning rod 306.

[0020] Both the fixed guide wheel 200 and the moving guide wheel 303 are made of silicone, which gives the fixed guide wheel 200 and the moving guide wheel 303 good damping performance, elasticity, softness and low coefficient of friction, which can reduce noise generation and have a buffering effect, thus reducing wear on the strip steel.

[0021] The bottom of the adjusting seat 100 is provided with a worktable, the top of the worktable is equipped with a torsion guide frame, and two limit frames are fixedly connected to the top of the worktable. The surface of the adjusting seat 100 is slidably connected to the inner wall of the limit frame. Screws are threadedly connected to the top of the adjusting seat 100 around its perimeter, and the surface of the screws is threadedly connected to the inner wall of the limit frame.

[0022] In this embodiment, when the strip needs to be twisted, a torsion guide frame of appropriate size is selected and installed on the top of the workbench with bolts. The adjusting seat 100 is pushed to move to a suitable position within the limiting frame. The screw is threaded into the limiting frame and the adjusting seat 100. The actuating block 305 is pushed to rotate the lead screw 304. The rotating lead screw 304 drives the shifting frame 302 to move within the protective sleeve 301. After the shifting frame 302 drives the moving guide wheel 303 to move to a suitable position, the actuating block 305 is stopped. The positioning rod 306 is pushed to move within the actuating block 305 and is locked in the reserved hole at one end of the protective sleeve 301. The long rod 307 is pushed down within the actuating block 305 and is locked in the positioning rod 306, thereby locking the lead screw 304.

[0023] At this time, the conveying mechanism guides the strip steel into the inside of the torsion guide trough frame. The moving strip steel moves along the torsion surface. Due to the special shape of the surface, the strip steel gradually twists during its forward movement. The strip steel moves through the area between the fixed guide wheel 200 and the moving guide wheel 303, which limits the movement of the strip steel and reduces the friction between the strip steel and the tail end of the torsion guide trough frame. When the position of the adjusting seat 100 at the top of the worktable is adjusted, the outlet direction of the strip steel can be changed. This allows for the collection of two or more strip steels by flipping without changing the position of the worktable. Finally, after reaching the required torsion angle, the strip steel is output from the outlet of the torsion guide trough frame.

[0024] like Figure 4 As shown, a magnetic block 308 is fixedly connected to the upper surface of the long rod 307. The actuating block 305 is an iron-cobalt-vanadium alloy component. The surface of the magnetic block 308 is magnetically attracted to the inner wall of the actuating block 305. A rubber ball 309 is fixedly connected to one side of the actuating block 305. The surface of the rubber ball 309 is engaged with the inner wall of the magnetic block 308. A spring 310 is fixedly connected to the end of the long rod 307. The top of the spring 310 is fixedly connected to the inner top wall of the actuating block 305. A limiting rod 311 is fixedly connected to the surface of the positioning rod 306. The surface of the limiting rod 311 is slidably connected to the inner wall of the actuating block 305.

[0025] The long rod 307, the rubber ball 309, and the spring 310 are all nitrile rubber components, which have high elasticity and good tensile properties.

[0026] In this embodiment, the elastic force of the spring 310 and the pushing force of the operator push the long rod 307 downward, so that the long rod 307 is locked in the positioning rod 306. As the magnetic block 308 moves downward, it squeezes the rubber ball 309 to produce deformation, so that the magnetic block 308 moves downward into the actuating block 305 and is attracted. The high elasticity of the rubber ball 309 automatically resets and is locked in the magnetic block 308.

[0027] like Figure 2As shown, a transparent block 313 is fixedly connected to the surface of the lead screw 304. One end of the transparent block 313 contacts one end of the protective sleeve 301, and the surface of the positioning rod 306 is slidably connected to the inner wall of the transparent block 313.

[0028] In this embodiment, the transparent block 313 is an acrylic plate component, and the limiting rod 311 is used to limit the movement range of the positioning rod 306 to prevent the positioning rod 306 from leaving the transparent block 313.

[0029] like Figure 3 As shown, two limiting blocks 312 are fixedly connected to the surface of the shift frame 302, and the surface of the limiting blocks 312 is slidably connected to the inner wall of the protective sleeve 301.

[0030] Working principle: Pushing the actuating block 305 causes the lead screw 304 to rotate, thereby adjusting the moving guide wheel 303 to move to a suitable position, pushing the positioning rod 306 to move within the actuating block 305 and lock it in the reserved hole at one end of the protective sleeve 301. The elastic force of the spring 310 and the pushing force of the operator push the long rod 307 down and lock it in the positioning rod 306. As the magnetic block 308 moves down, it squeezes the rubber ball 309 to deform, causing the magnetic block 308 to move down into the actuating block 305 and be attracted. The high elasticity of the rubber ball 309 automatically resets and locks it in the magnetic block 308, thereby locking the lead screw 304.

[0031] It should be noted that the adjusting seat 100, fixed guide wheel 200, moving guide wheel 303, lead screw 304, magnetic block 308 and actuating block 305 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
