Description

Technical Field

[0001] The invention relates to the field of material processing, in particular to a metal plate clamp assembly. Background Art

[0002] At present, the main technologies for nano-crystallization of metal sheets include surface mechanical attrition treatment. There are many surface treatment methods, such as surface mechanical attrition treatment (SMAT), surface mechanical attrition treatment (SMGT) and surface mechanical attrition treatment (SMRT). Double-sided surface mechanical rolling treatment (D-SMRT) is a surface nano-processing technology for sheet metal. It can process the upper and lower surfaces of metal sheets at the same time to obtain a gradient nanostructured surface. The SMRT tool with symmetry on the upper and lower surfaces of the device is driven by air pressure. The positive feedback regulation of air pressure can keep the tool output pressure stable during the processing and help the tool to adapt to the surface profile and thickness of the sheet metal. Its shortcomings are: during the installation process, the straight edge of the metal sheet is difficult to be parallel to the movement direction of the rolling tool. When processing the edge of the metal sheet, the ball head of the rolling tool is at risk of slipping, causing damage to the equipment; the rolling tool and its fixing device are easy to interfere with the sample clamping device, reducing the utilization rate of the material; when processing thin and soft metal sheets, the metal sheets are easy to deform and bend, and thick metal sheets are affected by the processing tool and cannot be clamped.

[0003] Existing sheet metal clamps have limited clamping force, and after long-term use, the clamping force may gradually weaken due to spring fatigue. The specifications and sizes of sheet metal clamps may be relatively fixed and cannot adapt to sheets of different sizes and shapes. During frequent use of sheet metal clamps, friction may occur between metal parts, resulting in surface wear or scratches. Although the surface of sheet metal clamps is usually electroplated, rust may still occur in humid or corrosive environments. In summary, existing sheet metal clamps have some defects in functionality, durability, design and aesthetics.

[0004] In the technical solution of patent CN202410384293.1, a metal plate clamping device is provided, which includes a work frame, an auxiliary component, a side clamping component, a bottom plate, a baffle, a sliding plate and a power part. The metal holding device is positioned at different positions of the work clamp by sliding the side clamping component to adapt to the needs of metal plates of different sizes, has stronger versatility, does not require manual disassembly and reinstallation, reduces manual labor intensity, and improves work efficiency.

[0005] With respect to the above-mentioned related technologies, the inventors found that there are at least the following problems in this technology: there is no calibration device in the invented device, and the accuracy is low; and the adsorption base has poor stability and is not suitable for use in large-scale metal rolling processes, which can easily cause the metal sheet to shift; the screw rod has no fixing device and is prone to unstable rotation during use, causing the rolling process to be unsmooth, affecting production efficiency. Summary of the invention

[0006] In order to overcome the problem that the prior art has no calibration components and cannot effectively adjust and calibrate the horizontal and vertical heights of the metal sheet, resulting in low accuracy and poor production quality in the subsequent metal sheet processing and rolling process, the present invention provides a metal sheet clamp assembly to overcome the above-mentioned shortcomings.

[0007] To achieve the above object, the present invention is implemented through the following technical solutions: A metal sheet clamp assembly: The invention comprises two sets of fixture assemblies and a calibration assembly for calibrating the two sets of fixture assemblies; Each set of clamp assemblies includes a base and a lower clamp with adjustable height, and also includes an upper clamp adapted to the lower clamp for clamping a metal sheet; The calibration assembly includes a spacing calibration piece for calibrating the spacing between the clamps, and a level adjustment device for adjusting the lower clamps of the two clamps to be at the same height.

[0008] The clamp assembly of the present invention includes an upper clamp and a lower clamp for clamping a target metal sheet. The lower clamp can adjust the upper and lower heights. After adjustment, the lower clamp is guaranteed to be on the same horizontal plane, thereby avoiding the problem that the lower clamp is not level and cannot be adjusted, resulting in skewness and instability during the subsequent rolling of the target metal sheet, and causing the product to have poor quality. At the same time, the upper clamp and the lower clamp can achieve precise clamping of the metal sheet, avoiding damage or scrapping of the sheet due to improper clamping, thereby saving material costs. The clamp assembly also includes a base for fixing the device to other subsequent devices. In order to increase the stability of the fixation, a number of screw holes can be set on the base, which is convenient for installation and disassembly, while also ensuring the stability of the device, avoiding instability during the clamping and rolling process, increasing the safety of the device, and facilitating more extensive promotion.

[0009] The calibration assembly described in the present invention includes a spacing calibration piece for adjusting the spacing width to adapt to plates of different widths, and a horizontal calibration piece for calibrating whether the clamp assemblies on both sides are on the same horizontal plane. The spacing calibration piece can adjust the width of the two clamp assemblies, and has high-precision adjustment capabilities, which can ensure the accuracy of the spacing between the clamps, which is crucial for fields that require precision processing. At the same time, through the spacing calibration piece, the spacing between the clamps can be easily adjusted to adapt to workpieces of different sizes or shapes, increasing the flexibility and adaptability of use. At the same time, the height adjustment device described in the present invention can be used to adjust and confirm that the horizontal height of the metal plate is consistent. If it is inconsistent, it is convenient for subsequent adjustments, avoiding inconsistent horizontal heights of the clamp assemblies on both sides, resulting in unstable clamping and affecting the dimensional uniformity of subsequent rolling, ensuring the flatness of the metal plate during subsequent processing, which is conducive to improving the dimensional uniformity of the metal plate after rolling, and is conducive to improving product quality.

[0010] Preferably, a support rod and a screw rod passing through the lower clamp are provided on the base, and the top ends of the support rod and the screw rod are fixedly connected by a fixing plate, and the screw rod drives the lower clamp to move up and down along the support rod.

[0011] The present invention is provided with a screw rod. On the one hand, the lower clamp can be adjusted up and down along the screw rod, and the upper clamp and the lower clamp can be used to clamp metal plates of different thicknesses, which reduces the time for disassembly and adjustment, is conducive to being applicable to different needs, and increases the breadth and applicability of the product. On the other hand, the screw rod has a high positioning accuracy, so that the clamp can accurately and stably clamp the workpiece to meet the needs of precision machining and assembly. And the screw rod has a high rigidity. This rigidity enables the clamp to maintain a stable clamping force when clamping the workpiece, avoiding loosening or displacement of the workpiece caused by vibration or external force interference. It can maintain stable performance during long-term use. This stability helps to ensure the clamping effect and machining accuracy of the clamp. At the same time, a number of support rods are provided on both sides of the screw rod to support and fix the entire device, which is conducive to increasing the stability of the entire device, reducing the force on the screw rod, reducing the loss of the screw rod, reducing the number of replacements, reducing costs, and being conducive to specific use in the production process.

[0012] The present invention provides a fixing plate to connect the fixed support rod and the screw rod, which is beneficial to ensuring the stability of the screw rod and the fixing rod in the device, and avoiding the shaking of the screw rod and the fixing rod which affects the stability of the metal splint, thereby affecting the subsequent processing process and causing the problem of poor product quality.

[0013] Preferably, the clamp assembly includes a bearing end cover connected to the upper side of the fixing plate for fixing the screw rod.

[0014] The present invention sets a bearing end cover connected to the threaded hole on the upper side of the fixing plate. On the one hand, the bearing end cover can effectively cover and seal the bearing housing to prevent dust, liquid, oil and other impurities from entering the bearing. This protective effect helps to keep the bearing clean and dry, reduce the occurrence of wear and failure, and can keep the bearing dry and operate normally in a humid or underwater environment. On the other hand, the bearing end cover can fix the outer ring of the bearing to prevent it from moving or shaking in the axial direction. This positioning effect helps to maintain the stability and accuracy of the screw rod and ensure the normal operation of the mechanical equipment; by adjusting the matching clearance between the bearing end cover and the bearing, the bearing clearance can be accurately controlled. This adjustment helps to optimize the operating state of the bearing, reduce friction and wear, and increase the service life. On the other hand, the bearing end cover can withstand the axial force from the screw rod and transmit it to other parts of the mechanical equipment. This load-bearing capacity helps to maintain the overall stability and structural integrity of the mechanical equipment and helps to reduce the vibration and noise of the screw rod during operation. The bearing end cover is usually fixed to the screw rod in a simple manner such as bolt connection or clamping connection, which is easy and quick to install. This design helps to reduce the installation cost and time of the mechanical equipment.

[0015] Preferably, the lower fixture is provided with a groove slide rail for connecting the calibration component, and the first connecting block and the second connecting block which are also used to connect in the groove slide rail are respectively provided on both sides of the spacing calibration component.

[0016] The calibration component of the present invention is connected to the lower fixture by sliding through the groove, which is conducive to quickly adjusting the spacing calibration piece at different positions of the lower fixture, reducing workmanship, increasing adjustment convenience, and making the equipment smoother and more efficient during operation. Reasonable component distance helps to reduce friction and vibration, thereby reducing energy consumption and noise, and improving the overall performance of the equipment. It is conducive to application in actual production processes.

[0017] Preferably, the relative edges of the two groups of lower clamps and upper clamps are respectively provided with a plurality of first positioning holes and second positioning holes for adapting to fixing metal sheets of different widths, and the first positioning holes and the second positioning holes are connected by bolts, thereby achieving the clamping of the metal sheets by the lower clamp and the upper clamp.

[0018] The present invention provides a first positioning hole and a second positioning hole, which is conducive to selecting different positioning holes for connection according to the size and shape of the metal plate, so as to better tightly clamp the metal plate, adapt to more metal plates of different shapes, and ensure the fastening of the clamping. At the same time, the bolt connection is easy to replace, avoiding the problem of inconvenience and high cost of replacement after aging.

[0019] Preferably, the opposing surfaces of the lower clamp and the upper clamp in the two sets of the clamp assemblies are provided with arc-shaped bosses for making the rolling tool fit.

[0020] The arc-shaped boss provided in the present invention is conducive to making the rolling tool overlap with the upper clamp, improving the utilization rate of the material, and reducing the loss caused by the continuous friction between the rolling tool and the metal clamp during use. It is conducive to long-term use and reduces the cost of subsequent maintenance and replacement of parts.

[0021] Preferably, the spacing calibration component comprises a first limit block and a second limit block slidably connected to the groove slide rail, and the first limit block and the second limit block are connected by a connecting rod with an adjustable length.

[0022] The two sets of clamps of the present invention are connected by a spacing calibration piece, and the spacing calibration piece can adjust the spacing width, which is conducive to being suitable for metal sheets with different width requirements. By adjusting the clamping spacing, the metal sheet is ensured to be stably and firmly clamped, avoiding processing errors or damage to the metal sheet caused by unstable clamping, and increasing the application range of the product. At the same time, by quickly and accurately adjusting the clamping spacing, the spacing adjustment piece helps to shorten the time for replacing and clamping the metal sheet, thereby improving the processing efficiency. This is particularly important for mass production and automated processing lines, which can significantly reduce production costs and improve overall production efficiency.

[0023] Preferably, the first limiting block comprises a first groove for accommodating one end of the connecting rod and being able to move therein, and also comprises a long strip limiting groove connected to the first groove for universal use, wherein the limiting groove is used to limit the connecting rod in the first groove by means of a bolt; The second limiting block includes a second groove for accommodating the other end of the connecting rod, and also includes a fixing hole connected to the second groove, and the fixing hole is connected to the connecting rod and the second groove by a bolt.

[0024] On the one hand, a bolt is connected in the limiting groove of the first limiting block, and the bolt further limits the connecting rod through friction. The second limiting block is provided with a bolt in the fixing hole, so that one end of the connecting rod is connected and fixed in the fixed position of the second groove, and the other end can adjust the depth in the first groove, which can be used to adjust the distance between the first limiting block and the second limiting block, thereby adjusting the spacing distance of the entire device. On the other hand, the present invention is provided with two spacing adjustment members, and different spacing adjustment members can be calibrated with each other to ensure that the spacing is consistent, thereby increasing the accuracy of the device, so that both sides of the metal plate do not deviate, and avoiding the phenomenon that one side of the metal plate has been calibrated and the other side is unstable, which is beneficial to subsequent processing operations and increases the quality of the product.

[0025] Preferably, the horizontal adjustment device includes a fixed column, and a receiving plate which is mounted on the fixed column and can move up and down; it also includes a positioning plate for positioning the fixed column on a subsequent device, and a plurality of connecting holes are provided on the positioning plate for connecting with bolts of the subsequent device.

[0026] The fixing column of the horizontal adjustment device of the present invention is provided with a thread for the receiving plate to slide up and down. The nuts are twisted up and down on the receiving plate to stabilize the position of the receiving plate to prevent it from sliding up and down unsteadily. The two ends of the receiving plate are respectively placed under the lower clamp. If they fit exactly, it means that the horizontal height calibration of the two clamp assemblies of the device is qualified and subsequent operations can be carried out; if they cannot be placed, it means that the horizontal heights of the two clamp assemblies of the device are different and need to be adjusted. The device increases the horizontal height accuracy of the entire device. At the same time, a positioning plate fixed with a nut is provided to facilitate disassembly after calibration and use, without affecting other subsequent operations.

[0027] Preferably, the level adjustment device comprises an extension plate connected to both sides of the receiving plate for extending the receiving plate.

DETAILED DESCRIPTION

[0039] The present invention is further described below in conjunction with specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work should fall within the scope of protection of the present invention.

[0040] Example 1 like Figure 1-5 As shown, this embodiment provides a metal sheet fixture assembly, which can be divided into a fixture assembly 10 and a calibration assembly 20.

[0041] On the one hand, the clamp assembly 10 includes a base 11 for fixing the device to a subsequent device, and a lower clamp 13 with adjustable height, and an upper clamp 14 adapted to the lower clamp 13 for clamping a metal sheet. The base 11 is provided with a support rod 16 and a screw rod 12 that pass through the lower clamp 13, and the top ends of the support rod 16 and the screw rod 12 are fixedly connected by a fixing plate 17.

[0042] In order to avoid the lower clamps 13 of the two groups of clamp assemblies 10 not being on the same horizontal plane, resulting in unstable clamping of the target metal sheet and affecting the subsequent rolling phenomenon, the lower clamp 13 is set to be able to adjust the height up and down along the screw rod 12, which is beneficial to increase product quality, increase the operability of the device, and save adjustment time while facilitating the height adjustment. In order to better adjust the above-mentioned lower clamp 13, a screw rod 12 is set, and the screw rod 12 has a high positioning accuracy, so that the clamp can accurately and stably clamp the workpiece, meet the requirements of precision machining and assembly, and increase the stability and accuracy of the clamping after calibration. At the same time, the screw rod 12 has a strong rigidity and can support the clamp assembly 10. In order to reduce the force on the screw rod, reduce the loss of the screw rod, reduce the number of replacements, and reduce costs, a number of support rods 16 are set to support and fix the entire device, which is beneficial to increase the stability of the entire device and is beneficial to specific use in the production process. In order to prevent the shaking of the screw rod 12 and the fixing rod 16 from affecting the stability of the metal clamp, a fixing plate 17 is provided at the top of the support rod 16 and the screw rod 12 to fix the connection through a fixing plate 17 .

[0043] In order to fix the target metal sheet and avoid the phenomenon that unstable clamping affects the subsequent rolling operation due to the different thickness, shape and size of the target metal sheet, an upper clamp 14 and a lower clamp 13 are set. On the opposite sides of the two groups of lower clamps 13 and upper clamps 14, a plurality of first positioning holes 132 and second positioning holes 141 are respectively set along the direction parallel to the fixed plate 17. When the metal sheet is small, the first positioning hole 132 on the inner side and the corresponding second positioning hole 141 are bolted; when the metal sheet is large, the first positioning hole 132 and the second positioning hole 141 on the outer side are bolted to better and tightly clamp the metal sheet, adapt to more metal sheets of different shapes, and ensure the tightness of the clamping. At the same time, the bolts connecting the first limiting hole 132 and the second limiting hole 141 can be adjusted according to the different thicknesses of the target sheet. When the metal sheet is thicker, the bolts are loosened to increase the distance between the lower clamp 13 and the upper clamp 14. When the metal sheet is thinner, the bolts are tightened to reduce the width between the lower clamp 13 and the upper clamp 14, so as to better stably clamp the target metal sheet. Moreover, the bolts themselves are high in strength and easy to replace, avoiding the problem of inconvenience and high cost of replacement after aging.

[0044] On the basis of the above-mentioned embodiment, in order to ensure the stability of the screw rod 12, the design of the clamp assembly 10 is further optimized.

[0045] The clamp assembly 10 also includes a bearing end cover 15 connected to the upper side of the fixing plate 17 for fixing the screw rod. The bearing end cover 15 is connected to the fixing plate 17 by bolts and contacts the screw rod 12. Since the screw rod 12 itself is set as a stepped structure, the bearing end cover 15 is set as a stepped structure matching the screw rod 12, which can better fix the spacing of the screw rod 12, avoid the screw rod 12 from shaking and unstable, and is convenient for disassembly and assembly, and is widely used in actual production. On the one hand, the bearing end cover 15 can effectively cover and seal the bearing housing to prevent dust, liquid, oil and other impurities from entering the bearing. On the other hand, the bearing end cover 15 can fix the outer ring of the bearing to prevent it from moving or shaking in the axial direction. This positioning effect helps to maintain the stability and accuracy of the screw rod 12 and ensure the normal operation of the mechanical equipment. On the other hand, the bearing end cover 15 can withstand the axial force from the screw rod and transmit it to other parts of the mechanical equipment. This load-bearing capacity helps to maintain the overall stability and structural integrity of the mechanical equipment and helps to reduce the vibration and noise of the screw rod 12 during operation.

[0046] On the basis of the above-mentioned embodiment, in order to improve the utilization rate of materials, the design of the clamp assembly 10 is further optimized.

[0047] The two sets of lower clamps 13 and upper clamps 14 have arc-shaped bosses on their opposite sides for the rolling tool to fit, so that the rolling tool overlaps with the upper clamp 14, reducing the loss caused by the continuous friction between the rolling tool and the metal clamp during use, improving the utilization rate of the material, facilitating long-term use, and reducing the cost of subsequent maintenance and replacement of parts.

[0048] On the other hand, the calibration assembly 20 described in the present invention includes a spacing calibration member 21 for adjusting the spacing width to adapt to plates of different widths, and a horizontal calibration member 22 for calibrating whether the clamp assemblies on both sides are on the same horizontal plane. The spacing calibration member 21 includes a first limit block 211 and a second limit block 212 that are slidably connected to the groove slide rail 131. The first limit block 211 and the second limit block 212 are connected by a connecting rod 213 with an adjustable length, which is conducive to being suitable for metal plates of different widths. By adjusting the clamping spacing, the metal plate is ensured to be stably and firmly clamped, avoiding processing errors or damage to the metal plate due to unstable clamping, and increasing the scope of application of the product. At the same time, the first limiting block 211 includes a first groove 2111 for accommodating one end of the connecting rod 213 and capable of moving therein, and also includes a long strip limiting groove 2112 connected to the first groove 2111, and the limiting groove 2112 is bolted to limit the connecting rod 213 in the first groove 2111; the second limiting block 212 includes a second groove 2121 for accommodating the other end of the connecting rod 213, and also includes a fixing hole 2122 connected to the second groove 2121, and the fixing hole 2122 is bolted to achieve a fixed connection between the connecting rod 213 and the second groove 2121. First, a bolt is connected in the limiting groove 2113 of the first limiting block 211, and the bolt further limits the connecting rod 213 through friction. The second limiting block 212 is provided with a bolt in the fixing hole 2122, so that one end of the connecting rod 213 is connected and fixed in the fixed position of the second groove 2121, and the other end can adjust the depth in the first groove 2111, which can be used to adjust the distance between the first limiting block 211 and the second limiting block 212, thereby adjusting the spacing distance of the entire device. On the other hand, the present invention sets two spacing adjustment members, and different spacing adjustment members can be calibrated with each other to ensure that the spacing is consistent, increase the accuracy of the device, and prevent the metal plate from being offset on both sides, avoiding the phenomenon that one side of the metal plate has been calibrated and the other side is unstable, which is beneficial to subsequent processing operations and increases the quality of the product. At the same time, a groove slide rail 131 for connecting the calibration component 20 is provided on the lower clamp 13, the first limit block 211 is provided with a first connecting block 2113 connected to the inner side of the groove slide rail 131, and the second limit block 212 is provided with a second connecting block 2123 connected to the inner side of the groove slide rail 131. The connecting blocks slide in the slide rail to adjust their positions, which is beneficial to reduce friction and vibration, thereby reducing energy consumption and noise, and improving the overall performance of the equipment, avoiding the problems of inconvenient adjustment of the spacing adjustment member 21 on the lower clamp 13, great difficulty in actual operation, and long operation time.When the target metal sheet is relatively large, slide the first limit block 211 and the second limit block 212 to the outer end of the groove slide rail 131 to increase the distance between the two sets of spacing calibration parts 21, which is conducive to stable clamping; when the target metal sheet is relatively small, slide the first limit block 211 and the second limit block 212 close to the inner side of the groove slide rail 131 to reduce the distance between the two sets of fixture calibration parts 21, so that the position of the first connecting block 2113 and the second connecting block 2123 in the groove slide rail 131 can be continuously adjusted according to the size of the target metal sheet, thereby adjusting the position of the fixture calibration part 21.

[0049] On the other hand, in order to ensure that the target metal sheet can be clamped stably and avoid the phenomenon of poor quality of subsequent rolled products caused by unstable clamping, a horizontal adjustment device 22 is provided for calibrating the horizontal height of the clamp assembly 10, including a fixed column 221, a thread is provided on the fixed column 221, and a receiving plate 222 is sleeved on the fixed column 221 and can move up and down, and both ends of the receiving plate 222 are placed under the lower clamp 13 to verify whether the clamp assembly 10 is horizontally aligned; it also includes a positioning plate 224 for positioning the fixed column 221 on the subsequent device, and a plurality of connecting holes 2241 are provided on the positioning plate 224 to be bolted to the subsequent device.

[0050] On the basis of the above-mentioned embodiment, in order to increase the application range of the level adjustment device, the calibration component 20 is further optimized in design.

[0051] When the receiving plate 222 is too short to rest on the clamp assemblies 10 on both sides, an extension plate 223 for extending the receiving plate 222 is connected on both sides of the receiving plate 222, which is conducive to being applicable to more target metal plates of different sizes and increasing the applicability of the product. If both sides of the extension plate 223 can rest on the bottom surface of the lower clamp 13, it means that the clamp assemblies 10 on both sides are on the same horizontal plane. If the extension plates 223 on both sides cannot just rest on the bottom surface of the lower clamp 13, it means that the clamp assemblies 10 on both sides are not on the same horizontal plane, and the height of the lower clamp 13 needs to be adjusted by the screw rods 12 on both sides to ensure that it is on the same horizontal plane for disassembly. The extension plate 223 is fixed to the receiving plate 222 by bolts for easy disassembly.

[0052] The specific use process of the embodiment is as follows: First, clamp the target metal sheet between the lower clamp 13 and the upper clamp 14, select the appropriate first positioning hole 132 and second positioning hole 141 according to the width of the metal sheet, adjust the tightness of the nut according to the different thickness of the target metal sheet, stably clamp the metal sheet, and complete the fixation of the metal sheet. Slide one end of the connecting rod 213 into the second groove 2121 of the second limit block 212, so that the bolt set in the fixing hole 2122 connects the connecting rod 213, fix one end of the connecting rod 213, and then insert the other end of the connecting rod 213 into the first groove 2111 of the first limit block 211, slide the bolt in the limit groove 2112, and complete the assembly of the spacing calibration part 21; push the first limit block 211 and the second limit block 212 into the groove slide rails 131 of the two sets of lower clamps 13 at the same time, connect them through the connecting block 2113, adjust the distance between the two bases 11 according to the size of the metal sheet, and fix the base 11 with bolts. The horizontal adjustment device 22 is fixedly connected between the two bases 11 with bolts, and whether to use the extension plate 223 is determined according to the distance between the two lower clamps. If the distance between the two lower clamps 13 is less than the length of the receiving plate 222, the extension plate 223 does not need to be connected; if the distance between the two lower clamps is greater than the length of the receiving plate 222, the bolts are tightened to fix the extension plate 223 on the receiving plate 222, and the bolts are tightened to fix the extension plate 223 on the receiving plate 222. If both ends of the extension plate 223 can be abutted against the lower side of the lower clamp 13, it means that the lower clamps 13 on both sides are on the same horizontal plane; if the extension plate 223 does not rest on the lower side of the lower clamps 13 on both sides, it means that the lower clamps 13 on both sides are not just on the same horizontal plane, and it is necessary to adjust the upper and lower heights of the lower clamps 13 set on the screw rod 12. Use a wrench to rotate the screw rod 12 to adjust the height of the lower clamp 13 so that the upper surface of the lower clamp 13 fits tightly with the lower surface of the extension plate 223 to complete the positioning of the horizontal surface of the metal plate. Remove the horizontal adjustment device 22, reinstall the spacing adjustment member 21, and adjust the length of the connecting rod 213 in the limiting groove 2113 according to the width of the metal plate; remove the spacing calibration member 21 to avoid interference between the spacing calibration member 21 and the rolling tool.
