Description

Technical Field

[0001] This utility model belongs to the technical field of roll support, specifically, it relates to a support for heat treatment of rolls. Background Technology

[0002] Rolls are the main components used in rolling steel plates. Therefore, during the production process of rolls, the outer surface of the rolls must undergo heat treatment such as quenching and tempering to obtain high outer surface hardness. When heat treating the surface of the rolls, multiple rolls are usually pushed into a heating furnace using a support frame. After the rolls are heated to the set temperature, the high-temperature rolls are removed from the heating furnace and then placed in a cooling pool for immersion in water to cool.

[0003] However, most existing supports have fixed placement positions for the rolls. This means that when dealing with rolls of different sizes, such as rolls of the same length but different diameters, the gap between them cannot be adjusted. As a result, the outer walls of adjacent rolls will stick together, leading to uneven heating and cooling of the rolls. Alternatively, the gap between adjacent rolls may be too large, wasting placement space and reducing heat treatment efficiency.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the problem that most existing supports have fixed placement positions for rolls, making it impossible to adjust the gap between rolls of different sizes (e.g., rolls of the same length but different diameters), this leads to adjacent rolls' outer walls touching, resulting in uneven heating and cooling, or excessively large gaps between adjacent rolls, wasting placement space and reducing heat treatment efficiency, the basic concept of this invention is as follows: A support for heat treatment of rolls includes a support and rollers connected to the bottom end of the support. An adjustment mechanism and a clamping and limiting mechanism are installed on the support. The adjustment mechanism includes a limiting slide groove formed on the inner side outer wall of the bracket. A limiting slider is slidably arranged on the inner wall of the limiting slide groove. A roller is installed on the limiting slider. The movable arrangement of the limiting slider and the limiting slide groove can drive the roller to adapt and adjust. The clamping and limiting mechanism includes a movable plate movably mounted on the bracket. The movable plate is used to drive the limiting slider to make lateral adjustment movements to adapt to rolls of different lengths.

[0006] In a preferred embodiment of this utility model, the adjustment mechanism includes a locking hole on one side of the outer wall of the limiting slider, the roller shafts on both sides of the roller are inserted into the inner wall of the locking hole, a connecting plate is connected to the top of the limiting slider, a sliding hole is opened on the outer wall of the connecting plate away from the limiting slider, a sliding rod is slidably arranged on the inner wall of the sliding hole, a pull plate is connected to the outer wall of one end of the sliding rod, and a positioning plate is connected to the end of the sliding rod away from the pull plate.

[0007] In a preferred embodiment of the present invention, the clamping and limiting mechanism includes a lead screw rotatably disposed at the bottom end of the bracket, a threaded connecting block being threadedly connected to the outer wall of the lead screw, the top end of the threaded connecting block being connected to the bottom end of the moving plate, and a rotating plate being connected to the end of the lead screw away from the bracket.

[0008] In a preferred embodiment of the present invention, a positioning hole is provided on one side of the outer wall of the bracket, and the outer wall of the positioning plate is inserted into the inner wall of the positioning hole and the two fit together properly.

[0009] In a preferred embodiment of this utility model, the outer walls of both sides of the movable plate are connected to supporting sliders, the inner outer wall of the bracket is provided with a movable groove, and the outer wall of the supporting slider is slidably disposed on the inner wall of the movable groove.

[0010] In a preferred embodiment of this utility model, the number of positioning holes is several, the number of positioning holes exceeds the number of limiting sliders, and the positioning holes are evenly and equidistantly distributed on the outer wall of the bracket.

[0011] In a preferred embodiment of this utility model, the outer wall of the supporting slider is fitted to the inner wall of the movable groove.

[0012] Compared with the prior art, the present invention has the following advantages: This invention utilizes a pull plate to move a sliding rod outward, causing the sliding rod to move the positioning plate synchronously. This disengages the outer wall of the positioning plate from the inner wall of the positioning hole, thus releasing the locking and limiting of the connecting plate and the limiting slider. Subsequently, the pull plate can be moved to move the limiting slider within the limiting groove. The movement of the limiting slider moves the position of the roller, allowing for adaptation and adjustment according to the size of adjacent rollers with different diameters. This prevents the outer walls of the rollers from sticking together due to different diameters, which would affect the heat treatment quality.

[0013] This invention utilizes a rotating plate to drive a lead screw to rotate. As the lead screw rotates, it moves a threaded connecting block, which in turn moves a moving plate at the top. This causes the limiting slider on the moving plate to move closer to the limiting slider on the bracket, thus enabling the bracket to adapt to and limit the fixing of rolls of different lengths, thereby improving its applicability.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 5 As shown, a support for heat treatment of rolls includes a support 1 and a roller 2 connected to the bottom of the support 1. An adjustment mechanism 31 and a clamping and limiting mechanism 32 are installed on the support 1. The adjustment mechanism 31 includes a limiting groove 311 formed on the inner outer wall of the support 1. A limiting slider 312 is slidably arranged on the inner wall of the limiting groove 311. A roll 319 is installed on the limiting slider 312. The movable arrangement of the limiting slider 312 and the limiting groove 311 can drive the roll 319 to adapt and adjust. The clamping and limiting mechanism 32 includes a movable plate 324 movably arranged on the support 1. The movable plate 324 is used to drive the limiting slider 312 to adjust laterally to adapt to rolls 319 of different lengths.

[0019] Furthermore, the adjustment mechanism 31 includes a locking hole 313 on one side of the outer wall of the limiting slider 312, and the roller shafts on both sides of the roller 319 are inserted into the inner wall of the locking hole 313. A connecting plate 314 is connected to the top of the limiting slider 312. A sliding hole is opened on the outer wall of the connecting plate 314 away from the limiting slider 312. A sliding rod 315 is slidably arranged on the inner wall of the sliding hole. A pull plate 316 is connected to the outer wall of one end of the sliding rod 315, and a positioning plate 318 is connected to the end of the sliding rod 315 away from the pull plate 316.

[0020] Furthermore, a positioning hole 317 is provided on one side of the outer wall of the bracket 1, and the outer wall of the positioning plate 318 is inserted into the inner wall of the positioning hole 317 and the two fit together properly, thereby improving the stability of the positioning plate 318 inserted into the positioning hole 317.

[0021] Furthermore, the number of positioning holes 317 exceeds the number of limiting sliders 312. The positioning holes 317 are evenly and equidistantly distributed on the outer wall of the bracket 1. This allows for adaptive adjustment of the limiting position according to the different diameter sizes of the rolls 319, thereby preventing the outer walls of adjacent rolls 319 from sticking together and affecting the quality of the heat treatment.

[0022] The clamping and limiting mechanism 32 includes a lead screw 321 rotatably disposed at the bottom end of the bracket 1. A threaded connecting block 323 is threadedly connected to the outer wall of the lead screw 321. The top end of the threaded connecting block 323 is connected to the bottom end of the moving plate 324. A rotating plate 322 is connected to the end of the lead screw 321 away from the bracket 1.

[0023] Furthermore, the outer walls on both sides of the movable plate 324 are connected to support sliders 325, and the inner outer wall of the bracket 1 is provided with a movable groove 326, and the outer wall of the support slider 325 is slidably disposed on the inner wall of the movable groove 326.

[0024] Furthermore, the outer wall of the support slider 325 is fitted to the inner wall of the moving groove 326, thereby improving the tightness of the fit between the support slider 325 and the moving groove 326, and thus improving the stability of the moving support of the moving plate 324.

[0025] The implementation principle of a support for heat treatment of rolls in this embodiment is as follows: The roll shaft of the roll 319 can be inserted into the slot 313 on the outer wall of the limiting slider 312. Then, the clamping and limiting mechanism 32 can clamp and limit multiple rolls 319 of different diameters but the same length. After installing and limiting multiple rolls 319, the position of the rolls 319 can be adjusted according to the different diameter gaps between adjacent rolls 319. First, adjust the leftmost or rightmost connecting plate 314, and then adjust the adjacent connecting plate 314. During adjustment, pull the pull plate 316 outward, causing the pull plate 316 to drive the slide rod 315 outward. As the slide rod 315 moves, it drives the positioning plate 318 to move outward synchronously, thereby causing its outer wall to disengage from the inner wall of the positioning hole 317. This allows for the adjustment of individual connecting plates. After the plate 314 and the limiting slider 312 are released from their locking positions, the pull plate 316 can be moved to drive the connecting plate 314 to move. As the connecting plate 314 moves, the limiting slider 312 moves along the inner wall of the limiting groove 311. This movement of the limiting slider 312 moves the fixed roller 319. After adjustment, the pull plate 316 can be pushed to move the sliding rod 315 back to its original position, so that the outer wall of the positioning plate 318 is inserted into the positioning hole 317. In this way, the positions of multiple connecting plates 314 and limiting sliders 312 can be adjusted in sequence. This allows for the adjustment of the appropriate distance between rollers 319 of different diameters, preventing adjacent rollers 319 from sticking together on their outer walls. At the same time, it ensures the number of rollers 319 placed, thereby improving the efficiency of the heat treatment of rollers 319 in one operation.

[0026] When it is necessary to limit and fix the roll 319, first insert the roller shaft on one side of the roll 319 into the inner wall of the locking hole 313 opened on the outer wall of the limiting slider 312 on one side. Then, rotate the rotating plate 322 to drive the lead screw 321 to rotate. The rotation of the lead screw 321 can drive the threaded connecting block 323 threaded on its outer wall to move. As the threaded connecting block 323 moves, it can drive the moving plate 324 at its top to move synchronously, so that the limiting slider 312 on the moving plate 324 gradually approaches the limiting slider 312 on the other side of the bracket 1, until the roller shaft on the other side of the roll 319 is inserted into the inner wall of the locking hole 313 on the other limiting slider 312. In this way, the rolls 319 of different lengths can be limited and fixed, thereby improving the applicability of the bracket 1.
