Description

Technical Field

[0001] This utility model belongs to the field of metal rolling technology, and in particular relates to a guiding and limiting mechanism for metal rolling processing. Background Technology

[0002] Metal rolling is a metal processing method that involves placing metal sheets or bars between rollers and applying pressure to plastically deform the metal material into the desired shape and size. It is widely used in the manufacturing industry for the production of metal sheets, pipes, bars and other products.

[0003] Metal sheets are usually fed directly into a rolling mill for rolling. Due to the lack of guiding and limiting mechanisms at the feed end, the metal sheets deviate during the process of entering the rolling mill, which ultimately affects the rolling effect. Moreover, the inability to transport the metal sheets horizontally will cause the rolled sheets to bend, which is not conducive to the flat rolling of the sheets.

[0004] To address the aforementioned issues, this application proposes a guiding and limiting mechanism for the rolling process of metal parts. Utility Model Content

[0005] The purpose of this invention is to provide a guiding and limiting mechanism for rolling metal parts, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a guiding and limiting mechanism for metal parts rolling processing, installed on a rolling mill. The rolling mill includes symmetrically arranged frames and a lower pressure roller and an upper pressure roller rotatably installed between the two frames. The guiding and limiting mechanism includes fixed seats fixedly installed on the two frames, and a rotating guide roller is provided between the two fixed seats. The guide roller is movable in the circumferential and axial directions. Several guide rollers are arranged horizontally, with adjacent guide rollers arranged diagonally. Each diagonal set of guide rollers is provided with a movable seat. A width adjustment mechanism is installed between the two movable seats to drive the two sets of guide rollers to move in opposite directions. Each movable seat is provided with a set of side guide wheels and an upper guide wheel. The upper end of the movable seat is connected to the upper guide wheel through a thickness adjustment mechanism.

[0008] Furthermore, a first extension rod is fixed to one end of the guide rod, and a second extension rod is fixed to the other end. The diameters of the first and second extension rods are both smaller than the diameter of the guide rod. Through holes for the movement of the first and second extension rods are provided on both the fixed seat and the movable seat. The guide rod on the same side is rotatably connected to the movable seat. The guide rod on the same side can rotate and slide axially with the fixed seat on the same side and the fixed seat and movable seat on the other side.

[0009] Furthermore, the two sets of side guide wheels are symmetrically located on both sides of the path through which the metal plate is fed into the rolling mill. Each set of side guide wheels consists of multiple side guide wheels, and the side guide wheels are rotatably mounted to the movable seat.

[0010] Furthermore, the width adjustment mechanism includes a bidirectional lead screw rotatably mounted between two fixed seats and an internal threaded sleeve fixed to the bottom of the movable seat. The internal threaded sleeve is also threadedly connected to the bidirectional lead screw. A horizontal adjustment wheel is rotatably mounted on one side of the fixed seat. The horizontal adjustment wheel is connected to the bidirectional lead screw via a bevel gear pair.

[0011] Furthermore, the thickness adjustment mechanism includes an extension plate fixed parallel to the top of the movable seat and a mounting bracket for mounting the upper guide wheels. Several upper guide wheels are provided along the length of the metal plate and are rotatably mounted on the mounting bracket.

[0012] Furthermore, the upper end of the mounting bracket is rotatably provided with an adjusting screw, the extension plate is fixedly provided with a threaded hole that is threadedly engaged with the adjusting screw, and the top of the adjusting screw is fixed with a vertical adjusting wheel.

[0013] Furthermore, the upper end of the mounting bracket is provided with symmetrical guide rods, and the extension plate has through holes that slide through the guide rods.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses diagonally distributed guide rollers to support the metal plate. The guide rollers can also be adjusted horizontally by a width adjustment mechanism to adapt to the guidance and limiting of metal plates of different widths. During the adjustment of the thickness adjustment mechanism, the positions of the side guide rollers and the upper guide rollers are also adjusted synchronously. The side guide rollers can effectively reduce friction with the side of the metal plate, and the upper guide rollers can be adjusted according to the different thicknesses of the metal plate, thereby ensuring that the metal plate is stably fed to the rolling mill.

[0024] 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 scope of protection of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 - Figure 4 As shown, the present invention is a metal part rolling processing guide and limiting mechanism, which is installed on a rolling mill 8. The rolling mill 8 includes symmetrically arranged frames 81 and a lower pressure roller 82 and an upper pressure roller 83 rotatably installed between the two frames 81. The upper pressure roller 83 is an active roller that rotates during rolling, and the metal plate is rolled between the lower pressure roller 82 and the upper pressure roller 83.

[0027] Specifically, the guide limiting mechanism includes a fixed base 1 fixedly installed on two frames 81, a rotating guide rod 2 between the two fixed bases 1, the guide rod 2 being able to move circumferentially and axially, several guide rods 2 arranged horizontally, two adjacent guide rods 2 being arranged diagonally, each of the two diagonally opposite sets of guide rods 2 being provided with a movable seat 3, a width adjustment mechanism 6 being installed between the two movable seats 3 to drive the two sets of guide rods 2 to move in opposite directions, each movable seat 3 being provided with a set of side guide wheels 4 and upper guide wheels 5, the upper end of the movable seat 3 being connected to the upper guide wheel 5 through a thickness adjustment mechanism 7.

[0028] Specifically, a first extension rod 21 is fixed to one end of the guide rod 2, and a second extension rod 22 is fixed to the other end. The diameters of the first extension rod 21 and the second extension rod 22 are both smaller than the diameter of the guide rod 2. Both the fixed seat 1 and the movable seat 3 have through holes for the movement of the first extension rod 21 and the second extension rod 22. In order to ensure that the movable seat 3 can directly drive the guide rod 2 to move synchronously axially after translation, the guide rod 2 on the same side is rotatably connected to the movable seat 3. In order to ensure the self-adaptability between the first extension rod 21 and the fixed seat 1 and the movable seat 3, the guide rod 2 on the same side and the fixed seat 1 on the same side, as well as the fixed seat 1 and the movable seat 3 on the other side, can rotate and slide axially.

[0029] In practical use, such as Figure 1 As shown, when the movable seat 3 on the left moves to the right, the movable seat 3 will directly drive the guide rod 2 to move to the right. At this time, the first extension rod 21 slides in the fixed seat 1 on the left, and the second extension rod 22 slides simultaneously in the fixed seat 1 and the movable seat 3 on the right, finally adjusting to the position as shown. Figure 3 The state shown.

[0030] Specifically, two sets of side guide wheels 4 are symmetrically located on both sides of the path through which the metal plate is fed into the rolling mill 8. Each set of side guide wheels 4 consists of multiple side guide wheels 4, and the side guide wheels 4 are rotatably mounted to the movable seat 3. More specifically, there are at least 3 side guide wheels 4. In this embodiment, in order to avoid the metal plate getting stuck between the top of the guide roller 2 and the side guide wheel 4, the gap between the guide roller 2 and the side guide wheel 4 is less than the minimum metal plate thickness.

[0031] Specifically, the width adjustment mechanism 6 includes a bidirectional lead screw 61 rotatably mounted between two fixed seats 1 and an internal threaded sleeve 62 fixed to the bottom of the movable seat 3. The internal threaded sleeve 62 is also threadedly connected to the bidirectional lead screw 61. A horizontal adjustment wheel 64 is rotatably mounted on one side of the fixed seat 1. The horizontal adjustment wheel 64 is connected to the bidirectional lead screw 61 through a bevel gear pair 63.

[0032] In use, after manually rotating the horizontal adjusting wheel 64, the double-acting screw 61 is driven to rotate in place at the bottom of the two fixed seats 1 under the action of the bevel gear pair 63. The internal thread sleeve 62 drives the two movable seats 3 to move inward or outward simultaneously through the screw of the double-acting screw 61, thereby adjusting the position between the two movable seats 3 and the upper guide wheel 4 and upper guide wheel 5 of the movable seats 3, and limiting the passage width of the metal plate.

[0033] Specifically, the thickness adjustment mechanism 7 includes an extension plate 71 that is fixed parallel to the top of the movable seat 3 and a mounting frame 74 for mounting the upper guide wheels 5. Several upper guide wheels 5 are provided along the length of the metal plate and are rotatably mounted on the mounting frame 74. In this embodiment, the multiple upper guide wheels 5 are arranged horizontally to ensure the horizontal and stable conveying of the metal plate; more specifically, there are at least 3 upper guide wheels 5.

[0034] Furthermore, the upper end of the mounting bracket 74 is rotatably provided with an adjusting screw 72, and the extension plate 71 is fixedly provided with a threaded hole 73 that is threadedly engaged with the adjusting screw 72. A vertical adjusting wheel 721 is fixedly provided on the top of the adjusting screw 72.

[0035] In use, the vertical adjusting wheel 721 drives the adjusting screw 72 to rotate on the mounting bracket 74. Since the threaded hole 73 is fixed on the extension plate 71, the axial movement force generated by the screwing of the two drives the mounting bracket 74 and the upper guide wheel 5 to rise and fall, thereby adapting to the vertical limit of metal plates of different thicknesses.

[0036] Furthermore, in order to ensure the lifting stability of the mounting bracket 74 and the upper guide wheel 5 at the lower end of the extension plate 71, the upper end of the mounting bracket 74 is provided with symmetrical guide rods 75, and the extension plate 71 is provided with through holes that slide through the guide rods 75.

[0037] It is understood that this utility model supports the metal plate with diagonally adjustable guide rollers to accommodate different widths; at the same time, the thickness adjustment mechanism adjusts the positions of the side guide rollers and the upper guide rollers simultaneously, the side guide rollers reduce friction, and the upper guide rollers adapt to different thicknesses, together ensuring that the metal plate is stably conveyed to the rolling mill.

[0038] One specific application of this embodiment is as follows: Figure 1-2 The figure shows the maximum opening width of the guide limit mechanism, at which point the metal plate between the two sets of side guide wheels 4 can be at its maximum width.

[0039] Width adjustment of the two sets of side guide wheels 4: The width between the two side guide wheels 4 is adjusted by the width adjustment mechanism 6. After the thickness adjustment mechanism 7 is driven, the guide rollers 2 on both sides move inward or outward at the same time. During this process, the guide rollers 2, side guide wheels 4 and upper guide wheels 5 move synchronously until the required width position is adjusted.

[0040] Then the metal plate is placed between the guide roller 2 and the side guide roller 4. The upper guide roller 5 is driven to move down by the width adjustment mechanism 6 until the upper guide roller 5 presses on the upper surface of the metal plate, thereby guiding and limiting the metal plate before it enters the rolling mill 8. Subsequently, the metal plate is rolled under the action of the rolling mill 8.
