Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, specifically to a guide roller opening degree adjustment device. Background Technology

[0002] Guide rollers are devices used in the rolling process of profile steel to guide the rolled workpiece into and out of the rolling pass. Their main function is to ensure that the rolled workpiece is accurately deformed in a predetermined direction and state. Guide rollers are installed before and after the rolling pass to help the rolled workpiece smoothly enter or exit the pass, ensuring the stability of the rolling process and the precision of the product. At present, the world's advanced guide rollers include SMS guide rollers, Morgan guide rollers, and FRS type guide rollers, etc. Each type of guide roller has its own characteristics, but the overall goal is to ensure the quality of wire rod products. The existing patent authorization announcement number CN217775154U discloses a guide roller opening degree adjustment device. The adjustment plate is inserted into the side of the guide roller near the guide roller through the plug-in post. Pushing the adjustment block causes the adjustment block to slide along the middle part of the two guide rollers towards the side closer to the guide. When the adjustment block is in contact with the side wall of the two guide rollers that are close to each other, the operator can read the opening scale on the adjustment block to know the opening width between the two guide rollers. Moving the adjustment block increases or decreases the opening width between the two guide rollers, thereby making corresponding adjustments to the opening degree of the guide rollers. When using the above-mentioned patent, multiple sets of opening scales are set in parallel on the adjusting block. When adjusting the opening, the adjusting block needs to be placed between two guide rollers. When adjusting, it is necessary to check the minimum distance between the guide rollers. The multiple sets of opening scales located between the guide rollers can easily interfere with the operator's vision and are not conducive to the operator's observation. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a guide roller opening adjustment device, comprising a guide body 1 and two guide rollers 2 symmetrically arranged on the left and right sides of the front side of the guide body 1. An adjustment assembly 3 is movably installed on the top of the guide body 1. The adjustment assembly 3 includes a guide frame 31, with an installation groove 32 inside the guide frame 31. A bidirectional threaded rod 33 is rotatably installed inside the installation groove 32 along the horizontal direction of the guide frame 31. A transmission box 34 is fixedly installed at one end of the guide frame 31. An observation opening 35 and a guide opening 36 are respectively opened on the top and front side of the guide frame 31. Two sliding blocks 37 symmetrically arranged on the left and right sides are threaded to the outside of the bidirectional threaded rod 33. An adjustment plate 38 is fixedly connected to the front side of the two sliding blocks 37. An observation opening 35 and a guide opening 36 are respectively opened on the top of the guide frame 31. By observing the reference scale 39 in front of the opening 35, the guide frame 31 is fixed to the guide body 1 and centered. The adjusting plate 38 is positioned between the two guide rollers 2. Then, by operating the bidirectional threaded rod 33 to rotate, the two sliding blocks 37 on the left and right sides of the bidirectional threaded rod 33, which are locked in the mounting groove 32, will move relative to each other in the horizontal direction of the bidirectional threaded rod 33. The two sliding blocks 37 move away from each other, causing the adjusting plate 38 to move. The adjusting plate 38 pushes the two guide rollers 2 to move to adjust the distance between the two guide rollers 2. The protrusions on the sliding blocks 37 correspond to the positions of the reference scale 39. By checking the reference scale 39, the distance between the two guide rollers 2 can be precisely adjusted. The separate reference scale 39 makes it convenient for the staff to check, avoids the situation of being confused by the sight, and ensures the accuracy of the adjustment.

[0016] A positioning block 315, centered horizontally, is fixedly installed at the bottom of the guide frame 31. A positioning slot 11, centered horizontally, is opened at the top of the guide body 1. The positioning block 315 is adapted to the positioning slot 11. During installation, the positioning block 315 is aligned with the positioning slot 11 and embedded therein, so that the guide frame 31 can be quickly centered on the guide body 1. This avoids errors in the subsequent adjustment of the guide roller 2 spacing due to the installation offset of the guide frame 31, and further improves the overall installation convenience and adjustment accuracy of the device.

[0017] The scale 39 is set with the center of the guide frame 31 as the zero point and extends to both ends of the guide frame 31. The scale design with the center as the zero point and extending to both ends allows the operator to intuitively read the displacement value of the sliding blocks 37 on both sides relative to the zero point when adjusting the distance between the two guide rollers 2. The actual distance between the guide rollers 2 can be quickly obtained by superimposing the values ​​on both sides without complicated calculations and conversions, which greatly simplifies the operation process. At the same time, the scale lines are made with clear laser engraving technology and eye-catching color markings, which can ensure that the operator can accurately read the values ​​even in the dimly lit industrial environment, effectively reducing the adjustment deviation caused by multiple sets of scales or inconvenient reading.

[0018] The top of the slider 37 is provided with a protrusion located in the observation opening 35. The protrusion is aligned with the reference scale 39. The protrusion is made of a material that contrasts sharply with the color of the reference scale 39. Its top surface is designed to be flat and parallel to the scale line. When the slider 37 moves along the guide frame 31, the protrusion can always be precisely aligned with the reference scale 39. The operator can directly use the scale value pointed to by the protrusion as the displacement reading of the slider 37 through the observation opening 35, avoiding reading errors caused by deviation of the viewing angle, and further ensuring the intuitiveness and accuracy of the spacing adjustment.

[0019] Please see Figure 3 , Figure 4 and Figure 5 A driven gear 311 is fixedly installed on the outside of the bidirectional threaded rod 33 facing the transmission box 34. A rotating shaft 312 is rotatably installed above the driven gear 311 inside the transmission box 34. A driving gear 313 that meshes with the driven gear 311 is fixedly installed on the outside of the rotating shaft 312. A handle 314 is fixedly installed on the end of the rotating shaft 312 outside the transmission box 34. By rotating the handle 314 located on one side of the guide frame 31 outside the transmission box 34, the rotating shaft 312 is driven to rotate, thereby driving the driving gear 313 inside the transmission box 34 to rotate. By meshing the driving gear 313 with the driven gear 311, the driven gear 311 can be rotated, and then the bidirectional threaded rod 33 in the mounting groove 32 is driven to rotate through the driving gear 313.

[0020] A handle 310 is fixedly installed on the top of the guide frame 31. The handle 310 facilitates the operation of the entire guide frame 31 by the operator. By holding the handle 310, the guide frame 31, together with its internal bidirectional threaded rod 33, mounting groove 32 and other components, can be easily moved. This provides convenience for the installation, maintenance and position adjustment of the equipment in different working scenarios, and further improves the operational flexibility of the device.

[0021] Working principle: When it is necessary to adjust the opening of the guide roller 2 on the guide body 1, the operator loosens the connecting bolts on the support arm on the guide body 1 used to install the guide roller 2, so that the guide roller 2 can move with the support arm within the guide body 1. Then, by holding the handle 310, the guide frame 31 is engaged in the positioning slot 11 using the positioning block 315 at its center, thus limiting the guide frame 31 to ensure that it is centered on the guide body 1. At this time, the adjusting plate 38 on the front side of the two sliding blocks 37 is located between the two guide rollers 2. Then, by rotating the handle 314 located outside the transmission box 34 on one side of the guide frame 31, the handle 314 drives the rotating shaft 312 to rotate, which in turn drives the drive gear 313 located in the transmission box 34 to rotate. The drive gear 313 meshes with the driven gear 311, which drives the driven gear 311 to rotate, and then the drive gear 313 drives the gear in the mounting slot 32 to rotate. The rotation of the bidirectional threaded rod 33 drives the two sliding blocks 37, which are locked in the mounting groove 32 on the left and right sides of its outer side, to move relative to each other along the horizontal direction of the bidirectional threaded rod 33. As the two sliding blocks 37 move away from each other, the adjusting plate 38 moves. The adjusting plate 38 pushes the two guide rollers 2 to move, thereby adjusting the distance between the two guide rollers 2. By referring to the position of the protrusion on the sliding block 37 on the reference scale 39, the distance between the two guide rollers 2 can be accurately adjusted. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
