Description

Technical Field

[0001] This invention relates to a wire drawing and forming process for wire drawing steel mesh, and particularly to a wire drawing and forming process for wire drawing steel mesh applied in the field of workpiece forming. Background Technology

[0002] Brushed steel mesh is mainly used in building insulation boards to limit and cover the insulation material while increasing its strength.

[0003] In existing technologies, metal mesh is generally formed by interlacing warp and weft threads, or by interlacing warp and weft threads and welding them together at the nodes for reinforcement. However, such metal mesh inevitably suffers wear and tear at the warp and weft thread connections during use, which makes the nodes prone to breakage, resulting in poor performance and low material utilization, leading to resource waste. Summary of the Invention

[0004] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the existing metal mesh has low quality and is prone to damage and breakage at the nodes.

[0005] To address the above problems, this invention provides a wire drawing and forming process for steel mesh, comprising the following steps: S1. First, put the steel strip into the unwinding machine, and then unwind it into the punching machine; S2. The stamping machine performs high-frequency stamping on the unwound steel strip to produce a steel strip with fine cuts. S3. Then, the steel strip with fine cuts is fed into the continuous roll forming and expanding equipment, and the roll forming and leveling, stretching and expanding and roll forming and leveling are repeated continuously to form a steel mesh with a parallelogram grid. The continuous roll forming and expanding equipment includes multiple roll forming equipment and multiple stretching equipment placed between two adjacent roll forming equipment. S4. Finally, cut the steel mesh to a certain length as needed, and then roll it up to complete the preparation of the wire mesh.

[0006] In the above-mentioned wire drawing and forming process of steel mesh, by cutting, leveling, expanding and leveling the steel strip, the steel strip can be made into an integrated mesh structure. Compared with the existing metal mesh structure with interwoven warp and weft threads, this effectively avoids wear and cracking at the nodes, and greatly improves the quality and service life of the metal mesh.

[0007] As a further improvement of this application, in step S2, the punching frequency of the stamping machine is 400-450 times / min, the steel strip thickness is 0.5mm, and the kerf size is 4mm*10mm.

[0008] As another improvement of this application, in step S3, during the leveling and expansion of the cut steel mesh, the number of stretching operations is no less than 3 times, and leveling is performed after each stretching and expansion. An angle detection device is set after the third expansion station to detect the stretching of the wire mesh. When the mesh reaches the stretching requirements, there is no need to stretch it again. Instead, step S4 is directly performed after leveling.

[0009] As a further improvement to this application, the angle detection equipment is equipped with an angle detection roller assembly, which includes a pressure roller and a printing roller arranged vertically opposite each other. The pressure roller is mounted on the upper part of the angle detection equipment via a lifting assembly, and the printing roller is mounted on the front and rear inner walls of the angle detection equipment via an electric rotating shaft. A high-definition camera is installed at the bottom of the angle detection equipment, with the camera's shooting end facing the lower left of the printing roller. A removal roller is also installed inside the angle detection equipment, located to the right of the printing roller. The roller expansion equipment is equipped with a controller, and the high-definition camera is signal-connected to the controller, which integrates an image analysis module.

[0010] As a further improvement to this application, a single ink removal roller is provided, and the ink removal roller is located to the lower right of the printing roller, with the surfaces of the ink removal roller and the printing roller in contact with each other.

[0011] As a further improvement to this application, the printing roller includes a roller body, which is composed of two semi-cylinders of different diameters joined together. The outer end of the smaller diameter semi-cylinder is wrapped with a fixed printing layer. The outer diameter of the fixed printing layer is the same as the diameter of the larger diameter semi-cylinder. The fixed printing layer is made of an elastically sealed material and is filled with a low-flow soft plastic material.

[0012] As another improvement of this application, two printing rollers are provided: A de-inking roller is located to the lower right of the printing roller, and the de-inking roller does not contact the printing roller; Another eraser roller is located directly to the right of the printing roller, and the surfaces of the eraser roller and the printing roller are in contact with each other.

[0013] As a further improvement to this application: the printing roller includes a roller body, which is composed of two semi-cylinders of different diameters joined together. The outer end of the smaller diameter semi-cylinder is wrapped with a printing belt. The printing belt includes a movable printing layer and two sets of limiting ropes fixedly connected between the two ends of the movable printing layer and the straight end of the adjacent larger diameter semi-cylinder of the roller body. The movable printing layer is an elastic sealing structure filled with a soft plastic material with low flowability. The limiting ropes are non-elastic structures.

[0014] As a further improvement to this application, a facilitator rod is placed between the printing belt and the small-diameter semi-cylinder. The facilitator rod is made of ferromagnetic material, and the facilitator roller, which does not contact the roller body, is made of electromagnetic material. Limiting plates are fixedly connected to the mutually distant outer ends of the small-diameter semi-cylinder of the roller body. The ends of the limiting plates extend outside the roller body, and the extension distance is not less than the distance between the printing roller and the facilitator roller at the lower right.

[0015] As a further improvement to this application, the same printing roller rotates in opposite directions for two consecutive inspections of the wire drawing steel mesh.

[0016] In summary, by performing cutting, leveling, expansion, and leveling operations on the steel strip, an integrated mesh structure can be formed. Compared to the existing interwoven metal mesh structure, this effectively avoids wear and cracking at the nodes, significantly improving the quality and service life of the metal mesh. During the production process, the angle detection roller group allows for monitoring of the mesh stretching after each expansion in the later stages of expansion. This facilitates timely detection of when the mesh meets the standards, effectively preventing overstretching. This not only ensures the quality of the finished wire mesh but also saves time and improves efficiency. Attached Figure Description

Detailed Implementation

[0019] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0020] First implementation method: Figure 1-2 This diagram illustrates a wire drawing and forming process for steel mesh, where 'a' represents a steel strip. The process includes the following steps: S1. First, put the steel strip into the unwinding machine, and then unwind it into the punching machine; S2. The stamping machine performs high-frequency stamping on the unwound steel strip to produce a steel strip with fine cuts. S3. Then, the steel strip with fine cuts is fed into the continuous roll forming and expanding equipment, thus repeatedly performing the roll forming and leveling-stretching and expanding-roll forming and leveling operations to form a steel mesh with a parallelogram grid, such as... Figure 3 In the figure, b represents the included angle in the vertical direction of the grid. During the multiple stretching and expansion processes, the included angle of the parallelogram in the vertical direction gradually increases, thereby achieving the horizontal length increase and expansion of the finished wire mesh. The continuous roller pressing and expansion equipment includes multiple roller pressing devices and multiple stretching devices placed between two adjacent roller pressing devices. S4. Finally, cut the steel mesh to a certain length as needed, and then roll it up to complete the preparation of the wire mesh.

[0021] In step S2, the punching frequency of the press is 400-450 times / min, the steel strip thickness is 0.5mm, and the kerf size is 4mm*10mm.

[0022] In the above-mentioned wire drawing and forming process of steel mesh, by cutting, leveling, expanding and leveling the steel strip, the steel strip can be made into an integrated mesh structure. Compared with the existing metal mesh structure with interwoven warp and weft threads, this effectively avoids wear and cracking at the nodes, and greatly improves the quality and service life of the metal mesh.

[0023] Second implementation method: This embodiment adds an angle detection device 1 and its related structures to the first embodiment, while the rest remains the same as the first embodiment.

[0024] like Figure 4In step S3, during the leveling and expansion process of the cut steel mesh, the stretching is performed no less than 3 times, and leveling is performed after each stretching and expansion. An angle detection device 1 is set up after the third expansion station to detect the stretching of the wire mesh. When the mesh meets the stretching requirements, there is no need to stretch it again. Instead, step S4 is directly performed after leveling. By setting up the angle detection device 1, the stretching can be detected after each stretching in the later stage of stretching. This can effectively prevent the wire mesh from continuing to stretch after it meets the standard, and thus effectively prevent the mesh edge from separating from the steel strip due to overstretching. This ensures the quality of the finished product and saves the time spent on the overall forming of the wire mesh, improving efficiency.

[0025] Angle detection equipment 1 is equipped with an angle detection roller group, which includes a pressure roller 2 and a printing roller 3 arranged vertically opposite each other. The printing roller 3 includes a roller body 31, which is composed of two semi-cylinders with different diameters. The outer end of the smaller diameter semi-cylinder is wrapped with a fixed printing layer 32. The outer diameter of the fixed printing layer 32 is the same as the diameter of the larger diameter semi-cylinder. The fixed printing layer 32 is made of an elastic sealing material. The surface of the fixed printing layer 32 can be coated with LINE-X coating to improve its elasticity and wear resistance, so that it is not easily worn and broken when in contact with the wire mesh. The fixed printing layer 32 is filled with a low-flow soft plastic material, such as clay. After being shaped, it is not easy to recover without external force, which can effectively maintain the accuracy of image information.

[0026] The pressure roller 2 is mounted on the upper end of the angle detection device 1 via a lifting assembly. The printing roller 3 is mounted on the front and rear inner walls of the angle detection device 1 via an electric rotating shaft. A high-definition camera 5 is installed at the bottom of the angle detection device 1, with the shooting end of the high-definition camera 5 facing the lower left of the printing roller 3. A removal roller 4 is also installed inside the angle detection device 1, located to the right of the printing roller 3. The roller expansion device is equipped with a controller, and the high-definition camera 5 is connected to the controller via a signal. The controller also integrates an image analysis module. During detection, when the wire mesh passes between the pressure roller 2 and the printing roller 3, the printing roller 3 rotates under the pressure of the pressure roller 2, causing its surface to continuously contact the surface of the wire mesh. Under the plasticity of the fixed printing layer 32, the surface of the printing roller 3 is printed with the shape of a grid. As it rotates, the image information of the grid is acquired by the high-definition camera 5. Through image processing, the controller can obtain the stretching condition of the wire mesh based on the angle of the grid in the image.

[0027] One eraser roller 4 is provided, and the eraser roller 4 is located to the lower right of the imprint roller 3. The eraser roller 4 and the imprint roller 3 are in contact with each other. As the imprint roller 3 continues to rotate, the fixed imprint layer 32 with the imprinted image comes into contact with the eraser roller 4. Under the roller pressure of the eraser roller 4, the image can be smoothed and eliminated before the fixed imprint layer 32 faces upward again, which facilitates the subsequent re-inspection of the wire mesh.

[0028] In summary, by performing cutting, leveling, expansion, and leveling operations on the steel strip, an integrated mesh structure can be formed. Compared to the existing interwoven metal mesh structure, this effectively avoids wear and cracking at the nodes, significantly improving the quality and service life of the metal mesh. During the production process, the angle detection roller group allows for monitoring of the mesh stretching after each expansion in the later stages of expansion. This facilitates timely detection of when the mesh meets the standards, effectively preventing overstretching. This not only ensures the quality of the finished wire mesh but also saves time and improves efficiency.

[0029] Second implementation method: This embodiment changes the specific arrangement of the printing roller 3 based on the first embodiment, while the rest remains the same as the first or second embodiment.

[0030] like Figure 7-8 The printing roller 3 includes a roller body 31, which is composed of two semi-cylinders with different diameters. The outer end of the smaller diameter semi-cylinder is wrapped with a printing belt. The printing belt includes a movable printing layer 301 and two sets of limiting ropes 302 fixedly connected between the two ends of the movable printing layer 301 and the straight end of the adjacent larger diameter semi-cylinder of the roller body 31. The movable printing layer 301 is an elastic sealing structure filled with a soft plastic material with low flowability, and the limiting ropes 302 are non-elastic structures.

[0031] like Figure 9 Two printing rollers 4 are set: An erasure roller 4 is located to the lower right of the imprinting roller 3, and the erasure roller 4 does not contact the imprinting roller 3. The erasure roller 4 is used to attract the erasure aid rod 6, so that the erasure aid rod 6 pushes the moving imprint layer 301 and deforms it toward the erasure roller 4. As the roller body 31 rotates, the entire moving imprint layer 301 can be pushed by the erasure aid rod 6, so that the soft plastic material in the moving imprint layer 301 is gathered and reorganized, so that the image information imprinted on it is more thoroughly eliminated and less likely to affect the next inspection.

[0032] Another eraser roller 4 is located directly to the right of the printing roller 3, and the eraser roller 4 is in contact with the surface of the printing roller 3. Due to the push of the eraser rod 6, the soft plastic material locally gathers and bulges in the moving printing layer 301. The eraser roller 4 is used to smooth out and eliminate the bulge, so that after the grid image of the printing is eliminated, the moving printing layer 301 can return to a relatively uniform and flat state, so that the pattern formed in the next printing is clearer and more accurate.

[0033] An eliminator rod 6 is placed between the printing belt and the small-diameter semi-cylinder. The eliminator rod 6 is made of ferromagnetic material, while the eliminator roller 4, which does not contact the roller body 31, is made of electromagnetic material. This allows the eliminator rod 6 to be attracted to the eliminator roller 4 when it reaches the lower right side during the rotation of the printing roller 3. As the printing roller 3 rotates, the eliminator rod 6 remains stationary relative to the eliminator roller 4, allowing the roller body 31 to continuously pass through the small gap between the eliminator roller 4 and the eliminator rod 6. This first squeezes and reshapes the internal soft plastic material, thus eliminating the printed image. Limiting plates 7 are fixedly connected to the mutually distant outer ends of the small-diameter semi-cylinder of the roller body 31. The ends of the limiting plates 7 extend outside the roller body 31, and the extension distance is not less than the distance between the printing roller 3 and the lower right eliminator roller 4. The limiting plates 7 are used to limit the movement of the eliminator rod 6, making it difficult for it to fall off the printing roller 3 when attracted by the eliminator roller 4, and allowing it to move relatively stably when attracted by the eliminator roller 4.

[0034] The same printing roller 3 rotates in opposite directions for two adjacent inspections of the wire mesh. After one rotation, the position of the extinguishing rod 6 relative to the moving printing layer 301 changes. The two rotations are in opposite directions, which allows the extinguishing rod 6 to continuously reciprocate between the moving printing layer 301 and the roller body 31. This ensures that the image information printed on the surface of the wire mesh can be stably eliminated after each inspection by the printing roller 3.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
