Description

Technical Field

[0001] The invention relates to the technical field of mesh cover deformation correction, in particular to an adjustable tooling device for metal mesh cover deformation correction. Background Art

[0002] Metal meshes are mass-produced and used in numerous industrial fields due to their unique physical properties and wide range of applications, including filtration, protection, and decoration. However, during the production process, especially after surface treatments such as electrophoresis or high-temperature painting, metal meshes often face a thorny issue: mesh deformation. This deformation is primarily caused by the shrinkage of the mesh during heating, resulting in a change in the overall shape. Deformation is particularly problematic and difficult to control for larger, irregularly shaped metal meshes.

[0003] Traditional correction methods typically use mold back pressure. This method has many limitations: First, mold production is expensive and requires customization based on different mesh shapes and sizes, increasing production costs. Second, correction using molds has a low success rate and is inefficient. Furthermore, in practice, accurately obtaining the appropriate correction data in one go is difficult, often requiring multiple attempts and adjustments, further extending production cycles and reducing efficiency.

[0004] Furthermore, traditional straightening methods require large equipment such as punching machines, which not only increases investment and maintenance costs but also places high demands on the operator's technical proficiency and experience. In actual production, improper operation or equipment failure can lead to poor straightening results and even damage to the metal mesh, resulting in further financial losses.

[0005] Therefore, in order to address the industry pain point of metal mesh deformation correction, there is an urgent need for a new correction device that can effectively solve the problems existing in the existing technology, improve correction efficiency and quality, reduce production costs, and at the same time have good adjustability and versatility to adapt to the correction needs of metal mesh covers of different shapes and sizes.

[0027] (3) Beneficial effects

[0028] Compared with the prior art, the present invention provides an adjustable tooling device for correcting deformation of a metal mesh cover, which has the following beneficial effects:

[0029] The present invention offers high adjustability and can accommodate metal mesh workpieces of various sizes and shapes. By adjusting the spacing between the bottom and top plates using a stopper, and by removably mounting the correction assembly in the conversion hole, correction can be performed for meshes of varying sizes and shapes. This eliminates the need for designing and manufacturing specialized molds for each mesh, effectively increasing the adaptability and flexibility of the correction process, saving significant time and effort, and improving correction efficiency.

[0030] The present invention uses an extrusion spring to squeeze the piston rod inside the upper cylinder upward, forming the contraction and reset of the upper pressure head, so that the metal mesh cover workpiece can automatically contract after the deformation correction is completed; the contraction of the upper pressure head can facilitate the replacement of the deformed metal mesh cover workpiece; the tension spring is used to pull the piston rod inside the lower cylinder downward, forming the expansion and reset of the lower pressure head, so that the metal mesh cover workpiece can be placed on several correction components and supported by the lower pressure head. The edges of the metal mesh cover workpiece at different positions and different heights can squeeze the lower pressure heads at different positions through the gravity of the metal mesh cover workpiece itself, so that the part of the lower pressure head can adaptively contract and change, so that the placed metal mesh cover workpiece is in a balanced state, thereby improving the accuracy of subsequent anti-deformation correction.

[0031] The present invention allows the internal hydraulic medium of the pressure cylinder to enter the interior of the upper cylinder through the pressure pipe and the adjusting cylinder, and the pressure thereof can drive the piston block to move upward. When the piston block moves upward, the gravity stopper can be driven to move upward through the adjusting shaft, and the upward movement of the gravity stopper can block the balance pipe, ensuring that when the metal mesh cover workpiece is positioned and clamped by the upper pressure head, the lower pressure head can be limited synchronously, thereby improving the stability of the positioning and clamping of the metal mesh cover workpiece, without the need to limit the lower pressure head separately, with the function of synchronous drive control, thereby improving the convenience and orderliness of operation.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1:

[0046] Refer to the attached Figures 1-4 An adjustable metal mesh deformation correction device includes a bottom plate 1 and a top plate 2, with a limit member and a guide member provided between the bottom plate 1 and the top plate 2; the limit member is used to adjust the distance between the bottom plate 1 and the top plate 2, thereby facilitating the disassembly and assembly of the correction mechanism and the installation and replacement of the metal mesh workpiece 6;

[0047] The guide member is used to guide the height-adjustable top plate 2, thereby improving the smoothness of the height adjustment of the top plate 2 and the center positioning effect of the multiple conversion holes 7 on the top plate 2 and the bottom plate 1;

[0048] A correction mechanism is provided between the bottom plate 1 and the top plate 2. The correction mechanism includes a plurality of correction components 8. The plurality of correction components 8 are used to position and correct the edge of the metal mesh cover workpiece 6.

[0049] The plurality of correction components 8 are provided to clamp the edge of the metal mesh cover workpiece 6 to achieve the positioning correction work of the metal mesh cover workpiece 6 after electrophoresis or high-temperature painting processing, thereby solving the problem that the metal mesh cover workpiece 6 shrinks after being heated after electrophoresis or high-temperature painting, causing the mesh cover to deform;

[0050] Adaptable to a variety of meshes: Traditional correction methods are usually designed for meshes of specific shapes and sizes. Once a mesh of a different specification is encountered, the mold must be redesigned or adjusted, which is time-consuming and labor-intensive. However, this device provides multiple conversion holes 7 inside the bottom plate 1 and top plate 2, allowing the correction component 8 to be flexibly installed in different positions according to the shape and size of the mesh. This allows a single tool to adapt to the correction needs of various meshes, eliminating the need for frequent mold replacement or adjustment, greatly improving the efficiency of the correction work.

[0051] Reduced mold costs: In the past, the need to produce numerous molds to accommodate metal grilles of varying sizes and shapes was high, and molds often required repair and maintenance after each use, increasing production costs. The adjustable design of this fixture eliminates the need for specialized molds for each grille type, saving significant mold production and maintenance costs.

[0052] Improve material utilization: Due to the good correction effect, the metal mesh can be restored to the required shape and size more accurately, reducing the situation where the mesh is scrapped or needs to be reprocessed due to improper correction, thereby improving the utilization rate of the metal mesh material, reducing the waste of raw materials, and further reducing production costs.

[0053] Easy Assembly and Adjustment: The correction assembly 8 is removably mounted between the bottom plate 1 and the top plate 2 via a conversion hole 7. This structural design facilitates assembly and disassembly, allowing operators to quickly install, remove, or replace the correction assembly 8 as needed, enhancing operational flexibility. Furthermore, the provision of stoppers and guides facilitates quick and easy height adjustment of the top plate 2, facilitating assembly and disassembly of the correction mechanism and installation and replacement of the metal mesh workpiece 6, further enhancing the ease of operation of the entire device.

[0054] Adaptable to Different Production Requirements: The device can be flexibly adjusted to meet the varying needs of actual production. For example, if correction of meshes of different shapes or sizes is required during production, simply adjusting the position and number of correction components 8 or replacing correction components 8 of different specifications is sufficient, without requiring large-scale modifications to the entire device. This allows for excellent adaptation to various changes in the production process, improving production flexibility and adaptability.

[0055] A plurality of conversion holes 7 are provided inside the bottom plate 1 and the top plate 2, and a plurality of correction components 8 are detachably installed between the bottom plate 1 and the top plate 2 through the conversion holes 7, and the plurality of correction components 8 are respectively arranged on the outer surface of the metal mesh cover workpiece 6;

[0056] By opening a plurality of conversion holes 7 inside the bottom plate 1 and the top plate 2, the correction component 8 can be easily installed at different positions between the bottom plate 1 and the top plate 2, thereby meeting the positioning and correction work of metal mesh cover workpieces 6 of different shapes and sizes. By arranging a plurality of correction components 8 on the outer surface of the metal mesh cover workpiece 6 respectively, the integrity of the positioning and correction of the metal mesh cover workpiece 6 can be further improved.

[0057] Refer to the attached Figure 1 and Figure 2 , the guide member includes at least two guide shafts 3, and the at least two guide shafts 3 are arranged between the bottom plate 1 and the top plate 2;

[0058] The setting of the guide shaft 3 is used to improve the smoothness of the height adjustment of the top plate 2 and the center positioning of several conversion holes 7 on the top plate 2 and the bottom plate 1, thereby improving the verticality of the correction component 8 after installation.

[0059] Refer to the attached Figure 1 and Figure 2The limiting member includes a threaded rod 4 fixed to the top of the bottom plate 1 and a threaded sleeve 5 rotatably connected to the inside of the top plate 2, and the top end of the threaded rod 4 is threadedly installed in the inside of the threaded sleeve 5;

[0060] By driving the threaded sleeve 5 in rotation, the threaded sleeve 5 can form an up and down movement on the threaded rod 4. Through the up and down movement of the threaded sleeve 5, the position of the top plate 2 can be height-adjusted and locked after adjustment, thereby facilitating the disassembly and assembly of the correction mechanism and the installation and replacement of the metal mesh cover workpiece 6.

[0061] It should be noted here that the limiting member also includes but is not limited to a cylinder, a motor, etc. for driving the top plate 2 in height.

[0062] Refer to the attached Figure 3 and Figure 4 , the correction assembly 8 includes an upper pressure head 81, a lower pressure head 82 and an adjusting member;

[0063] It should be noted here that the upper pressing head 81 and the lower pressing head 82 are made of PU material, and the edges of the mesh cover are supported according to the maximum and minimum positive and negative deformation points, and the deformed mesh cover is placed on the tooling for correction work;

[0064] The adjusting member is used to adjust the upper pressing head 81 and the lower pressing head 82 up and down, and the edge of the metal mesh workpiece 6 is positioned and clamped by the relative movement of the upper pressing head 81 and the lower pressing head 82;

[0065] The adjusting part is set to adjust the upper pressure head 81 and the lower pressure head 82 up and down, so that the upper pressure head 81 and the lower pressure head 82 can move relative to or apart from each other. The edge of the metal mesh cover workpiece 6 is positioned and clamped by the relative movement of the upper pressure head 81 and the lower pressure head 82, so as to avoid the problem of the metal mesh cover workpiece 6 shrinking due to the heat after electrophoresis or high-temperature painting, thereby causing the mesh cover to deform.

[0066] It should be noted here that the adjustment member includes a screw rod, a cylinder and other structures for adjusting the upper pressure head 81 and the lower pressure head 82 up and down;

[0067] Refer to the attached Figure 3 and Figure 4 The adjusting member includes a screw 83 detachably mounted on the top plate 2 and the bottom plate 1. The outer surfaces of the two screws 83 are threadedly connected with a fastening nut 84, and the interiors of the upper pressure head 81 and the lower pressure head 82 are provided with a through hole for the screw 83 to be inserted through.

[0068] When the upper pressing head 81 and the lower pressing head 82 are used to clamp the edge of the metal mesh cover workpiece 6, by rotating the fastening nuts 84 on the two lead screws 83, the upper pressing head 81 and the lower pressing head 82 can be driven to move relative to or away from each other, thereby fixing and clamping the edge of the metal mesh cover workpiece 6;

[0069] It should be noted here that the two fastening nuts 84 mentioned above are the nuts closest to the upper pressure head 81 and the lower pressure head 82, and the fastening nuts 84 can be connected to the upper pressure head 81 and the lower pressure head 82 in a rotating connection manner, so as to facilitate better adjustment of the upper pressure head 81 and the lower pressure head 82;

[0070] One end of the lead screw 83 is used to be inserted into the interior of the conversion hole 7 and is tightened and limited by one of the fastening nuts 84. The other end of the lead screw 83 is used to be inserted into the interior of the upper pressure head 81 or the lower pressure head 82 and is tightened and limited by the other fastening nut 84.

[0071] One end of the lead screw 83 is inserted into the interior of the conversion hole 7, and another fastening nut 84 is used to tighten and limit the position. When the top plate 2 is pressed down, the fastening nut 84 can be tightened with the bottom plate 1 or the top plate 2, so that when the top plate 2 is pressed down, the pressure head is driven to move, forming a fixed clamping of the edge of the metal mesh cover workpiece 6, and by rotating the fastening nut 84, not only the initial position of the pressure head is adjusted to increase or decrease the distance between the pressure head and the edge of the metal mesh cover workpiece 6, further improving the convenience of its subsequent positioning and correction, but also it is convenient for the staff to directly disassemble and assemble the correction component 8 to achieve installation work in different positions, thereby meeting the positioning and correction work of metal mesh cover workpieces 6 of different shapes or sizes.

[0072] Specific parameter setting: Use high-strength rubber material on the tooling, support the edge of the mesh cover according to the maximum and minimum positive and negative deformation points, place the deformed mesh cover on the tooling, rotate the screw 83 at the support point, and for positive deformation, rotate the upper screw 83 downward and the lower screw lower. Repeatedly adjust the screw length of the high and low points of deformation until the negative deformation is released and the mesh cover is flat.

[0073] This precise positioning and correction method can effectively reduce possible errors during the correction process, improve the correction quality, and more effectively solve the problem of heat deformation of the mesh after electrophoresis or high-temperature painting, ensuring the dimensional accuracy and shape regularity of the mesh.

[0074] Example 2: Based on Example 1, the difference is that;

[0075] Refer to the attached Figure 5-Figure 8 The adjusting member includes a driving cylinder 9 and a pressure unit 15 detachably mounted on the top plate 2 and the bottom plate 1 , and both driving cylinders 9 are provided with a magnet block 10 for adsorbing on the top plate 2 or the bottom plate 1 ;

[0076] The magnet block 10 is provided to mount the driving cylinder 9 in the adjusting member on the top plate 2 or bottom plate 1 made of metal by adsorption;

[0077] The interior of the two driving cylinders 9 is slidably connected to a piston rod 11, one end of each piston rod 11 extends to the outside of the driving cylinder 9, and the upper pressure head 81 and the lower pressure head 82 are fixedly connected to the two piston rods 11 respectively;

[0078] The lower pressing heads 82 in the plurality of correction assemblies 8 are used to support the metal mesh cover workpiece 6, and the corresponding upper pressing heads 81 move downward to position and clamp the metal mesh cover workpiece 6.

[0079] The pressure unit 15 is used to press the piston rod 11 fixed to the upper pressure head 81 downward;

[0080] The pressure unit 15 is provided to drive the piston rod 11 fixed to the upper pressure head 81, so that the piston rod 11 drives the upper pressure head 81 to move up and down. The downward movement of the upper pressure head 81 can drive the edge of the metal mesh workpiece 6 supported by the lower pressure head 82 to position and clamp.

[0081] It should be noted here that the pressure unit 15 includes but is not limited to an electric telescopic rod for driving the piston rod 11 to extend and retract.

[0082] Refer to the attached Figure 7 and Figure 8 , the two driving cylinders 9 are respectively an upper cylinder and a lower cylinder, and a compression spring 12 and a tension spring 13 are respectively provided inside the upper cylinder and the lower cylinder;

[0083] The extrusion spring 12 is provided to press the piston rod 11 inside the upper cylinder upward, thereby causing the upper pressure head 81 to retract and reset, so that the metal mesh cover workpiece 6 automatically retracts after the deformation correction is completed. The contraction of the upper pressure head 81 facilitates the replacement of the deformed metal mesh cover workpiece 6.

[0084] The tension spring 13 is provided to pull the piston rod 11 inside the lower cylinder downward, thereby expanding and resetting the lower pressure head 82, so that the metal mesh cover workpiece 6 can be placed on several correction components 8 and supported by the lower pressure head 82. The edges of the metal mesh cover workpiece 6 at different positions and heights can squeeze the lower pressure heads 82 at different positions due to its own gravity, so that the lower pressure heads 82 of this part can shrink and change adaptively, thereby making the metal mesh cover workpiece 6 in a balanced state after placement, thereby improving the accuracy of subsequent anti-deformation correction.

[0085] Refer to the attached Figure 7 and Figure 8 , the injection ends of the upper and lower barrels are fixedly connected with a necking block 14;

[0086] The setting of the necking block 14 is used to control the pressure increase or pressure relief inside the driving cylinder 9 to prevent the pressure adjustment from being too large, which causes the upper pressure head 81 or the lower pressure head 82 to stretch too much instantly, thereby uniformly reducing the accuracy of the positioning and clamping of the metal mesh workpiece 6, thereby affecting the subsequent correction effect;

[0087] Specifically, the necking block 14 provided inside the upper cylinder can reduce the liquid flow rate during liquid injection or discharge, thereby reducing the speed of the upper pressure head 81 moving up and down, thereby improving the adaptability and accuracy of the upper pressure head 81 in positioning and clamping the metal mesh workpiece 6;

[0088] By means of the necking block 14 arranged inside the lower cylinder, the metal mesh cover workpiece 6 is placed on a number of correction components 8 and supported by a number of lower pressure heads 82. During the supporting process, since the metal mesh cover workpiece 6 is in different shapes or sizes, the lower pressure heads 82 at different positions slowly shrink, thereby ensuring the stability of the metal mesh cover workpiece 6 during storage, and effectively avoiding the problem that when the metal mesh cover workpiece 6 is driven by staff or other pressure, the lower pressure heads 82 at different positions will have instantaneous large movements, thereby affecting the balance of the metal mesh cover workpiece 6.

[0089] Example 3: Based on Example 1, the difference is that;

[0090] Refer to the attached Figure 5 and Figure 6 The pressure unit 15 includes a pressure cylinder 151 and a circulation cylinder 152 fixed to each other. A piston plate 154 driven by an electric cylinder 153 is provided inside the pressure cylinder 151. One end of the pressure cylinder 151 is fixedly connected to the injection port of the upper cylinder through a pressure pipe.

[0091] The electric cylinder 153 is connected to an external power source and a control switch, and is used to drive the piston plate 154 to extend and retract. The movement of the piston plate 154 can squeeze the hydraulic medium inside the pressure cylinder 151, allowing the hydraulic medium to enter the interior of the upper cylinder, so that the piston rod 11 drives the upper pressure head 81 to move downward, cooperating with the lower pressure head 82 to position and clamp the edge of the metal mesh workpiece;

[0092] It should be noted here that the interiors of the pressure cylinder 151, the circulation cylinder 152 and the two drive cylinders 9 are all filled with hydraulic medium;

[0093] A sealing plate 155 is slidably connected to the interior of the circulation barrel 152, and the bottom of the circulation barrel 152 is fixedly connected to the injection port of the lower barrel through a balance pipe;

[0094] The sealing plate 155 is provided to adaptively adjust the hydraulic medium inside the circulation cylinder 152. The tension spring 13 inside the lower cylinder allows the piston rod 11 to drive the lower pressure head 82 to fully expand. By placing the metal mesh cover workpiece 6 on top of several lower pressure heads 82, the different shapes of the metal mesh cover workpiece 6 allow the lower pressure heads 82 at different positions to contract. When the lower pressure head 82 contracts, the hydraulic medium inside the lower cylinder can enter the interior of the circulation cylinder 152, thereby releasing pressure.

[0095] An adjusting cylinder 156 is fixedly connected between the pressure pipe and the balancing pipe. The adjusting cylinder 156 has openings at the top and bottom. A spacer is fixedly connected to the inside of the adjusting cylinder 156. An adjusting shaft 157 is slidably connected to the inside of the spacer via a sealing sleeve. The top and bottom ends of the adjusting shaft 157 are fixedly connected to a piston block 158 and a gravity stopper 159, respectively.

[0096] An adjusting cylinder 156 is fixedly connected between the pressure pipe and the balance pipe, and the adjusting cylinder 156 is provided to continuously drive the upper pressure head 81 and the lower pressure head 82;

[0097] The specific operation is as follows: the internal hydraulic medium of the pressure cylinder 151 enters the interior of the upper cylinder through the pressure tube and the adjusting cylinder 156, and its pressure can drive the piston block 158 to move upward. When the piston block 158 moves upward, the gravity stopper 159 can be driven to move upward through the adjusting shaft 157, and the upward movement of the gravity stopper 159 can block the balance pipe, ensuring that when the metal mesh cover workpiece 6 is positioned and clamped by the upper pressure head 81, the lower pressure head 82 can be limited synchronously, thereby improving the stability of the positioning and clamping of the metal mesh cover workpiece 6, without the need to limit the lower pressure head 82 separately, with the function of synchronous drive control, which improves the convenience and orderliness of operation.

[0098] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
