Description

Technical Field

[0001] This utility model relates to the field of stress rolling mill technology, and in particular to a stress rolling mill height fine adjustment mechanism. Background Technology

[0002] In existing technology, a stress rolling mill is a piece of equipment used for metal processing. Its main function is to remove internal stress in metal materials through the rolling process, thereby improving the microstructure and mechanical properties of the materials. It increases the strength and toughness of materials by applying a certain pressure, causing plastic deformation in the metal during cooling and processing.

[0003] A search revealed a utility model patent with Chinese patent publication number CN221246481U, which discloses a rolling line adjustment device. The device includes mounting plates for installation on the rolling line, a base plate between the mounting plates, a lead screw end seat on the mounting plate, and a center seat on the base plate. A double-ended lead screw passes through the center seat and the two lead screw end seats. The threads on the double-ended lead screw are symmetrical about the center seat. One end of the double-ended lead screw is rotatably mounted on a rotary encoder, and the other end is connected to a reducer connected to a motor. Two lower wedges are connected to the double-ended lead screw, and upper wedges are located on the inclined surfaces of the lower wedges. A balancing mechanism connects the two upper wedges. A proximity switch for shutting off the motor is located on one side of one of the mounting plates, and a signal plate for triggering the proximity switch is located on the bottom surface of one of the lower wedges. The purpose of this utility model is to provide a rolling line adjustment device that improves the reliability of self-locking and facilitates the determination of the adjustment amount. Although the rolling line adjustment device in the above-mentioned utility model solves the problem of piston retraction caused by internal leakage of pressure oil in the hydraulic cylinder, it adjusts the rolling line height by raising and lowering the upper wedge block, but does not have an independent roll gap adjustment mechanism. The roll gap (the distance between the upper and lower rolls) needs to rely on other external structures or be passively adjusted. Furthermore, the balancing mechanism relies on the internal spring and balance bar to force the upper wedge block to move synchronously. The spring is prone to fatigue under long-term load, resulting in a height deviation between the upper wedge blocks on both sides. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a height fine-tuning mechanism for stress rolling mill lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A height fine-tuning mechanism for a stress rolling mill includes a lower support, a rolling line adjustment mechanism fixedly connected to the top and bottom of the lower support, lower rolls rotatably connected to both sides of the inner wall of the lower support, a guide column fixedly connected to the top of the lower support, a support seat fixedly connected to one side of the lower support, and a roll gap adjustment mechanism fixedly connected to the top of the support seat.

[0007] As a further embodiment of this utility model: the outer wall of the guide column is slidably connected to an upper bracket, and the inner walls of the upper bracket are rotatably connected to upper rollers.

[0008] As a further embodiment of this utility model: the rolling line adjustment mechanism includes a connecting seat, a motor, an arc-shaped pad, an upper wedge block, a lower wedge block, and a screw, with the upper wedge block fixedly connected to the bottom of the lower support.

[0009] As a further embodiment of this utility model: the connecting seat is fixedly connected to the top of the upper wedge block by a connecting plate, the motor is rotatably connected to both sides of the inner wall of the connecting seat, the arc-shaped pad is rotatably connected to one side of the upper wedge block, and the lower wedge block is slidably connected to the bottom of the upper wedge block.

[0010] As a further embodiment of this utility model: the screw is threadedly connected to the inner wall of the arc-shaped pad, and the arc-shaped pad away from the motor is rotatably connected to the lower wedge block, and the screw is threadedly connected to the arc-shaped pad away from the motor, and the screw is fixedly connected to the output shaft of the motor.

[0011] As a further embodiment of this utility model: the roller gap adjustment mechanism includes a lifting plate, a second motor and a second screw, and the lifting plate is fixedly connected to the top of the upper support.

[0012] As a further embodiment of this utility model: the second motor is fixedly connected to the top of the support base, the second screw is fixedly connected to the output shaft of the second motor, and the second screw is connected to the lifting plate by a thread.

[0013] Compared with the prior art, this utility model provides a height fine-tuning mechanism for a stress rolling mill, which has the following advantages:

[0014] 1. A height fine-tuning mechanism for a stress rolling mill, when it is necessary to raise the rolling line, can drive the lower support and lower roll to move obliquely upward through the rolling line adjustment mechanism. At this time, the support seat sleeved on the outer wall of the guide column will drive the upper roll to move together with the lower support, thereby realizing the height adjustment of the rolling line. When it is necessary to adjust the distance between the lower roll and the upper roll, the roll gap adjustment mechanism can make the upper support slide along the outer wall of the guide column, thereby realizing the distance between the lower roll and the upper roll. Thus, the rolling line adjustment mechanism can adjust the height of the rolling line with the lower roll as a reference, and at the same time, it can adjust the roll gap.

[0015] 2. This stress rolling mill height fine-tuning mechanism, when the height of the rolling line needs to be adjusted, starts motor one, which drives screw one to rotate. The rotation of screw one causes it to move axially within the arc-shaped pad. The lower wedge block and the upper wedge block are engaged by a wedge-shaped inclined surface. The sliding of the lower wedge block, through the action of the wedge-shaped inclined surface, causes the upper wedge block to move vertically. During this process, the rotatably connected arc-shaped pad can rotate to a certain extent, thereby adapting to the angle change between screw one and the lower wedge block, thus driving the lower and upper rolls to rise and fall, thereby achieving fine-tuning of the rolling line height. Therefore, the threaded connection between screw one and the arc-shaped pad has high transmission accuracy, which can accurately convert the rotational motion of motor one into axial displacement, further improving the accuracy of height adjustment. At the same time, the arc-shaped pad can compensate for this angle change by rotating, avoiding motion interference or jamming caused by angle deviation, and ensuring the smoothness and stability of the mechanism's movement.

[0016] 3. This stress rolling mill height fine-tuning mechanism, when the roll gap needs to be adjusted, starts motor two, whose output shaft drives screw two to rotate. Since screw two is threadedly connected to lifting plate, and lifting plate is fixedly connected to the top of upper support, the rotational motion of screw two is converted into vertical displacement of lifting plate under the restriction of guide column. Upper support slides along guide column, thereby driving the upper roll on its inner wall to move up and down, thereby changing the distance between upper and lower rolls and realizing roll gap adjustment. Thus, the cooperation between screw two and lifting plate accurately converts the rotational motion of motor into vertical displacement, ensuring the accuracy of roll gap adjustment, effectively controlling the thickness of rolled workpiece, and improving product dimensional accuracy and quality stability.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A height fine-tuning mechanism for a stress rolling mill, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a lower support 2, a rolling line adjustment mechanism 1 fixedly connected to the top and bottom of the lower support 2, lower rollers 3 rotatably connected to both sides of the inner wall of the lower support 2, a guide column 8 fixedly connected to the top of the lower support 2, an upper support 5 slidably connected to the outer wall of the guide column 8, an upper roller 6 rotatably connected to both sides of the inner wall of the upper support 5, a support base 4 fixedly connected to one side of the lower support 2, and a roller gap adjustment mechanism 7 fixedly connected to the top of the support base 4.

[0028] When it is necessary to raise the rolling line, the lower support 2 and the lower roll 3 can be moved obliquely upward by the rolling line adjustment mechanism 1. At this time, the support seat 4 sleeved on the outer wall of the guide column 8 will drive the upper roll 6 to move together with the lower support 2, so as to realize the height adjustment of the rolling line.

[0029] When it is necessary to adjust the distance between the lower roll 3 and the upper roll 6, the roll gap adjustment mechanism 7 allows the upper support 5 to slide along the outer wall of the guide column 8, thereby adjusting the distance between the lower roll 3 and the upper roll 6. Thus, the rolling line adjustment mechanism 1 can adjust the rolling line height with the lower roll 3 as a reference, and at the same time adjust the roll gap.

[0030] In order to fine-tune the height of the rolling line, such as Figure 2 and Figure 3 As shown, the rolling line adjustment mechanism 1 includes a connecting seat 101, a motor 102, an arc-shaped pad 103, an upper wedge block 104, a lower wedge block 105, and a screw 106. The upper wedge block 104 is fixedly connected to the bottom of the lower support 2. The connecting seat 101 is fixedly connected to the top of the upper wedge block 104 through a connecting plate. The motor 102 is rotatably connected to both sides of the inner wall of the connecting seat 101. The arc-shaped pad 103 is rotatably connected to one side of the upper wedge block 104. The lower wedge block 105 is slidably connected to the bottom of the upper wedge block 104. The screw 106 is threadedly connected to the inner wall of the arc-shaped pad 103. The arc-shaped pad 103 away from the motor 102 is rotatably connected to the lower wedge block 105. The screw 106 is threadedly connected to the arc-shaped pad 103 away from the motor. The screw 106 is fixedly connected to the output shaft of the motor 102.

[0031] When the height of the rolling line needs to be adjusted, motor 102 is started, which drives screw 106 to rotate. The rotation of screw 106 causes it to move axially within the arc-shaped pad 103. The lower wedge block 105 and the upper wedge block 104 are engaged by a wedge-shaped inclined surface. The sliding of the lower wedge block 105, through the action of the wedge-shaped inclined surface, causes the upper wedge block 104 to move vertically. During this process, the rotatably connected arc-shaped pad 103 can rotate to a certain extent, thereby adapting to the movement of screw 106 and the lower wedge block 104. The angle change between the wedge blocks 105 drives the lower roll 3 and the upper roll 6 to rise and fall, thereby achieving fine adjustment of the height of the rolling line. As a result, the threaded connection between the screw 106 and the arc-shaped pad 103 has high transmission accuracy, which can accurately convert the rotational motion of the motor 102 into axial displacement, further improving the accuracy of height adjustment. At the same time, the arc-shaped pad 103 can compensate for this angle change by rotating, avoiding motion interference or jamming caused by angle deviation, and ensuring the smoothness and stability of the mechanism's movement.

[0032] To adjust the roller gap, such as Figure 4 and Figure 5 As shown, the roll gap adjustment mechanism 7 includes a lifting plate 701, a second motor 702, and a second screw 703. The lifting plate 701 is fixedly connected to the top of the upper bracket 5, the second motor 702 is fixedly connected to the top of the support base 4, and the second screw 703 is fixedly connected to the output shaft of the second motor 702. The second screw 703 and the lifting plate 701 are connected by threads.

[0033] When the roll gap needs to be adjusted, motor 2 702 is started, and its output shaft drives screw 2 703 to rotate. Since screw 2 703 is connected to lifting plate 701 by a thread, and lifting plate 701 is fixedly connected to the top of upper bracket 5, the rotational motion of screw 2 703 is converted into vertical displacement of lifting plate 701 under the restriction of guide column 8. Upper bracket 5 slides along guide column 8, thereby driving the upper roller 6 on its inner wall to move up and down, thereby changing the distance between upper roller 6 and lower roller 3, realizing the adjustment of roll gap. Thus, the cooperation between screw 2 703 and lifting plate 701 accurately converts the rotational motion of the motor into vertical displacement, ensuring the accuracy of roll gap adjustment, effectively controlling the thickness of rolled parts, and improving the dimensional accuracy and quality stability of products.

[0034] Working principle: When it is necessary to raise the rolling line, the rolling line adjustment mechanism 1 can drive the lower support 2 and the lower roll 3 to move obliquely upward. At this time, the support seat 4 sleeved on the outer wall of the guide column 8 will drive the upper roll 6 to move together with the lower support 2, thereby realizing the height adjustment of the rolling line.

[0035] When it is necessary to adjust the distance between the lower roll 3 and the upper roll 6, the upper support 5 can slide along the outer wall of the guide column 8 through the roll gap adjustment mechanism 7, thereby adjusting the distance between the lower roll 3 and the upper roll 6.

[0036] When the height of the rolling line needs to be adjusted, motor 102 is started, which drives screw 106 to rotate. The rotation of screw 106 causes it to move axially within the arc-shaped pad 103. The lower wedge block 105 and the upper wedge block 104 are engaged by a wedge-shaped inclined surface. The sliding of the lower wedge block 105 causes the upper wedge block 104 to move vertically through the action of the wedge-shaped inclined surface. During this process, the rotatably connected arc-shaped pad 103 can rotate to a certain extent to adapt to the angle change between screw 106 and lower wedge block 105, thereby driving the lower roll 3 and upper roll 6 to rise and fall, thus achieving fine adjustment of the rolling line height.

[0037] When the roll gap needs to be adjusted, motor 702 is started, and its output shaft drives screw 703 to rotate. Since screw 703 is connected to lifting plate 701 by a thread and lifting plate 701 is fixedly connected to the top of upper bracket 5, the rotational motion of screw 703 is converted into vertical displacement of lifting plate 701 under the restriction of guide column 8. Upper bracket 5 slides along guide column 8, thereby driving the upper roller 6 on its inner wall to move up and down, thereby changing the distance between upper roller 6 and lower roller 3, and realizing the adjustment of roll gap.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
