Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strips, and in particular to a tool steel strip flatness adjustment device. Background Technology
[0002] In the production and processing of tool steel strips, the flatness of the strip directly affects its subsequent processing quality and application performance. Processes such as stamping and welding have extremely high requirements for the flatness of the strip. However, existing strip flatness adjustment equipment has many technical bottlenecks. Traditional equipment mostly uses a rigid pressure plate structure, which cannot adaptively adjust according to the thickness differences and unevenness of different parts of the strip when applying pressure for flattening. This easily leads to uneven pressure distribution, which not only makes it difficult to effectively eliminate defects such as waviness and warping of the strip, but may also cause problems such as scratches and excessive deformation on the strip surface due to excessive local pressure, reducing the yield and surface quality of the strip.
[0003] Therefore, it is necessary to provide a new tool steel strip flatness adjustment device to solve the above-mentioned technical problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, a tool steel strip flatness adjustment device is provided to solve the above-mentioned problems.
[0005] The tool steel strip flatness adjustment device provided by this utility model includes: two horizontal plates; the bottom of the two horizontal plates on their relatively close sides are connected to a base plate, and a boss is installed on the top of the base plate; wherein, an elastic pressure plate assembly is provided above the boss on the relatively close side of the two horizontal plates for leveling the steel strip placed on the lower boss; a lifting guide assembly is installed at the bottom of the relatively close side of the two horizontal plates, and the elastic pressure plate assembly can be moved up and down by the lifting guide assembly.
[0006] Preferably, the elastic pressure plate assembly includes a lower pressure plate, which is located above the boss. A cross support plate is provided above the lower pressure plate. A support block is installed on one side of the center of the bottom of the cross support plate. Slide rods are installed around the support block. A slider is slidably connected to the outside of each slide rod. A buffer rod is connected to the bottom of each slider. The bottom of each buffer rod is connected to the top of the lower pressure plate.
[0007] Preferably, a buffer spring is sleeved on the outer side of each slider, and the buffer spring is located between the slider and the support block.
[0008] Preferably, each of the slide bars is connected to a connecting plate at the end away from the support block, and the top of each connecting plate is connected to the bottom of the cross support plate.

[0010] Preferably, the lifting guide assembly includes a fixed plate that is connected to both horizontal plates, and the fixed plate is located above the cross support plate. A cross lifting plate is provided above the fixed plate. Lifting rods are connected to the bottom of each of the four corners of the cross lifting plate. The bottom of each lifting rod passes through the fixed plate and is connected to the top of the cross support plate. An electric push rod for driving the cross lifting plate to reciprocate is installed at the top of the fixed plate.
[0011] Compared with related technologies, the tool steel strip flatness adjustment device provided by this utility model has the following beneficial effects:
[0012] The elastic pressure plate assembly of this invention, through the cooperation of a buffer rod, a buffer spring, and a slider, can automatically adjust the pressure distribution and position of the lower pressure plate according to the unevenness and thickness difference of the steel strip surface, achieving precise adaptive leveling of the steel strip.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] This utility model provides a tool steel strip flatness adjustment device, which includes: two horizontal plates 1; the bottom of the two horizontal plates 1 on the side that is relatively close to each other is connected to a base plate 11, and a boss 12 is installed on the top of the base plate 11; wherein, an elastic pressure plate assembly is provided on the side of the two horizontal plates 1 that is relatively close to each other above the boss 12, for leveling the steel strip placed on the lower boss 12; a lifting guide assembly is installed on the bottom of the side of the two horizontal plates 1 that is relatively close to each other, and the elastic pressure plate assembly can be moved up and down by the lifting guide assembly.
[0021] It should be noted that there are two horizontal plates 1, arranged opposite each other, which form the main support structure of the entire tool steel strip flatness adjustment device. Their bottoms are connected to the base plate 11, forming a stable frame and providing an installation foundation for the elastic pressure plate assembly and the lifting guide assembly. Conveying assemblies are installed at both ends of the two horizontal plates 1 on their relatively close sides, enabling the conveying of the steel strip. The boss 12 is installed on top of the base plate 11, below the elastic pressure plate assembly, and serves as a support platform for placing the steel strip to be flattened. Its flat surface provides a precise support reference surface for the steel strip. The elastic pressure plate assembly is located on the relatively close side of the two horizontal plates 1, above the boss 12, and is the core functional component for achieving steel strip flatness adjustment. It applies uniform pressure to the steel strip placed on the boss 12, causing plastic deformation and eliminating surface defects such as waves and warping. The elastic design of the elastic pressure plate assembly allows it to automatically adjust the pressure distribution according to the actual conditions of the steel strip, ensuring appropriate pressure in steel strip areas of different positions and thicknesses, thereby achieving precise flatness adjustment. The lifting guide assembly is installed at the bottom of the two horizontal plates 1 on opposite sides and is connected to the elastic pressure plate assembly. It is mainly used to control the up-and-down movement of the elastic pressure plate assembly. It can precisely guide the elastic pressure plate assembly to rise and fall smoothly in the vertical direction, ensuring that the elastic pressure plate assembly remains parallel to the boss 12 during operation, so that pressure is applied evenly to the steel strip.
[0022] In an embodiment of this utility model, the elastic pressure plate assembly includes a lower pressure plate 2, which is located above the boss 12. A cross support plate 21 is provided above the lower pressure plate 2. A support block 22 is installed on one side of the center of the bottom of the cross support plate 21. Slide rods 23 are installed around the support block 22. A slider 24 is slidably connected to the outside of each slide rod 23. A buffer rod 25 is connected to the bottom of each slider 24. The bottom of each buffer rod 25 is connected to the top of the lower pressure plate 2. A buffer spring 26 is sleeved on the outside of each slide rod 23. The buffer spring 26 is located between the slider 24 and the support block 22. A connecting plate 27 is connected to the end of each slide rod 23 away from the support block 22. The top of each connecting plate 27 is connected to the bottom of the cross support plate 21. The top of each slider 24 is slidably connected to the bottom of the cross support plate 21.
[0023] It should be noted that the lower pressure plate 2, located above the boss 12, is the component that directly contacts the steel strip to be leveled and is a key actuator for adjusting the flatness of the steel strip. During operation, the lower pressure plate 2 evenly transmits pressure to the steel strip, causing it to undergo plastic deformation under pressure, thereby eliminating surface unevenness defects. Its smooth surface ensures uniform pressure distribution when in contact with the steel strip, avoiding scratches or damage to the steel strip surface. The cross support plate 21, positioned above the lower pressure plate 2, acts as a connecting element, providing structural support and a force transmission path for the entire elastic pressure plate assembly. It evenly distributes the pressure from above to each component. The support block 22, installed on the center side of the bottom of the cross support plate 21, is the core node for force transmission and structural support in the elastic pressure plate assembly. Multiple slide rods 23, installed around the support block 22, provide sliding tracks for the slider 24 and are key components for realizing the elastic buffering function of the elastic pressure plate assembly. The slider 24 can slide outside the slide rod 23. When the elastic pressure plate assembly is subjected to external force, the slider 24 can move along the slide rod 23, driving the buffer rod 25 and the lower pressure plate 2 to move. The bottom of the buffer rod 25 is connected to the top of the lower pressure plate 2, and the top is connected to the slider 24, serving to connect the lower pressure plate 2 and the slider 24, and providing buffering and support between them. When the elastic pressure plate assembly applies pressure to the steel strip, the buffer rod 25 can absorb and buffer the pressure impact, avoiding damage to the surface of the steel strip caused by excessive instantaneous pressure. At the same time, the buffer rod 25 has a certain elastic deformation capacity, which can expand and contract according to the shape and thickness of the steel strip, so that the lower pressure plate 2 can better fit the surface of the steel strip, ensuring uniform pressure transmission and achieving precise leveling of the steel strip. The buffer spring 26 is sleeved on the outside of the slide rod 23, located between the slider 24 and the support block 22, and is the core component for the elastic pressure plate assembly to achieve the elastic buffering function. When the elastic pressure plate assembly is subjected to external force, the buffer spring 26 will undergo compression or tension deformation, absorbing and storing energy, thereby buffering the pressure impact and reducing the instantaneous pressure of the lower pressure plate 2 on the steel strip. When the external force decreases, the buffer spring 26 releases energy, pushing the slider 24 and the lower pressure plate 2 back to their original positions, enabling the lower pressure plate 2 to continuously apply stable pressure to the steel strip. The connecting plate 27 is connected to the end of the slide rod 23 away from the support block 22, and its top is connected to the bottom of the cross support plate 21. It is used to fix the slide rod 23 and ensure that the slide rod 23 maintains a stable position during operation.
[0024] In an embodiment of this utility model, the lifting guide assembly includes a fixed plate 3 that is connected to the two horizontal plates 1. The fixed plate 3 is located above the cross support plate 21. A cross lifting plate 31 is provided above the fixed plate 3. Lifting rods 32 are connected to the bottom of the four corners of the cross lifting plate 31. The bottom of each lifting rod 32 passes through the fixed plate 3 and is connected to the top of the cross support plate 21. An electric push rod for driving the cross lifting plate 31 to move back and forth is installed on the top of the fixed plate 3.
[0025] It should be noted that the fixed plate 3 connects between the two horizontal plates 1 and is located above the cross support plate 21, serving as the basic load-bearing structure for the lifting guide assembly. Simultaneously, the fixed plate 3 has a through hole for the lifting rod 32 to pass through, providing lateral support while ensuring the lifting rod 32 can move freely up and down, preventing it from swaying or shifting during lifting and ensuring the stability and accuracy of the elastic pressure plate assembly's lifting movement. The cross lifting plate 31 is positioned above the fixed plate 3; its shape helps to evenly distribute force and is a key component connecting the electric push rod and the elastic pressure plate assembly. The lifting rod 32 is connected to the four corners of the cross lifting plate 31, transmitting the power of the electric push rod to the elastic pressure plate assembly. Driven by the electric push rod, the cross lifting plate 31 moves up and down reciprocally, causing the lifting rod 32 to move synchronously, thereby realizing the lifting and lowering of the elastic pressure plate assembly. Its cross-shaped structure ensures that the force is evenly applied to all parts of the elastic pressure plate assembly during the lifting process, avoiding tilting of the elastic pressure plate assembly due to uneven force, ensuring the uniformity of pressure applied to the steel strip, and improving the accuracy of steel strip flatness adjustment.
[0026] The working principle of the tool steel strip flatness adjustment device provided by this utility model is as follows: When using the tool steel strip flatness adjustment device of this utility model, first place the tool steel strip to be flattened on the boss 12. According to the specifications of the steel strip and the initial flatness, the electric push rod installed on the top of the fixed plate 3 is activated by the control system. The electric push rod extends or retracts, driving the cross lifting plate 31 to move back and forth in the vertical direction. The lifting rods 32 connected to the bottom of the four corners of the cross lifting plate 31, driven by the cross lifting plate 31, pass through the through holes on the fixed plate 3 and move up and down synchronously. The movement of the lifting rods 32 is transmitted to the elastic pressure plate assembly connected to the top of the cross support plate 21, so that the elastic pressure plate assembly gradually approaches the steel strip. During the descent of the elastic pressure plate assembly, the fixed plate 3 guides and supports the lifting rods 32, ensuring that the elastic pressure plate assembly descends vertically and smoothly until the lower pressure plate 2 contacts the surface of the steel strip. After the lower pressure plate 2 contacts the steel strip, if there is unevenness or thickness difference on the surface of the steel strip, the buffer rod 25 and the buffer spring 26 play their role. The buffer rod 25 can extend and retract according to the force applied, allowing the lower pressure plate 2 to adaptively conform to the surface of the steel strip. The buffer spring 26 undergoes compression deformation under pressure, absorbing the pressure impact and preventing the lower pressure plate 2 from exerting excessive instantaneous pressure on the steel strip. Simultaneously, the slider 24 slides on the slide rod 23, causing the buffer rod 25 and the lower pressure plate 2 to finely adjust their positions, ensuring that the lower pressure plate 2 applies appropriate and uniform pressure to the steel strip at different positions. Under pressure, the steel strip undergoes plastic deformation, and its unevenness defects such as waves and warping are gradually eliminated.
