Description

Technical Field

[0001] The invention belongs to the field of explosion-proof and explosion-suppressing materials, in particular to a processing technology of spherical metal barrier explosion-proof and explosion-suppressing materials. Background Art

[0002] With the rapid development of society, the demand for gasoline, diesel and flammable and explosive hazardous chemicals continues to increase. During transportation, the storage and refueling stations are close to people's activities and buildings, which poses a great safety hazard. Therefore, barrier explosion-proof and explosion-suppression materials are installed in the tanks of transport tank trucks and storage tanks. In extreme situations such as lightning strikes, external collisions and ruptures, and fires, the transport tanks and storage tanks will not deflagrate or explode, greatly reducing accident damage.

[0003] The existing barrier explosion-proof and explosion-suppression materials are cylinders composed of multiple three-dimensional polygons. They are too large to be easily loaded by machines and need to be loaded manually. There is a high probability of work-related injuries when people work in confined spaces. Some storage tanks are used and may have residual harmful liquids or gases, which increases the harm to workers and even causes casualties. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a processing technology for spherical metal barrier explosion-proof and explosion-suppressing materials to solve the problem in the prior art that barrier explosion-proof and explosion-suppressing materials are large in size and inconvenient to be filled by machinery, and require manual entry into the tank for filling.

[0005] A processing technology for a spherical metal barrier explosion-proof and explosion-suppression material comprises the following steps:

[0006] Step 1: Raw material pretreatment

[0007] Select the metal coils that meet the requirements and flatten them through the rolling process to ensure the surface flatness and uniformity of the metal coils, providing a good foundation for subsequent processing;

[0008] Step 2: Rolling and forming

[0009] The metal coil pretreated in step 1 is subjected to rolling cutting, and parallel and staggered cuts are cut on the surface of the metal coil by selecting appropriate rolling cutting tools and process parameters to form a metal material with cuts;

[0010] Step 3: Expand and expand

[0011] The metal material with the cutout in step 2 is fed into an expansion and pulling device, and opened in a direction perpendicular to the cutout by mechanical force to form a three-dimensional polygonal mesh metal material;

[0012] Step 4: Slitting

[0013] The three-dimensional polygonal mesh metal material expanded and stretched in step 3 is sheared to cut it into multiple sections of three-dimensional polygonal mesh metal material having the same shape;

[0014] Step 5: Rolling and pressing into a ball shape

[0015] The three-dimensional polygonal mesh metal material obtained in step four is rolled together and then sent into the spinning forming equipment in sequence. Through the action of the mold and the spinning process, it is gradually pressed into a sphere to obtain an irregularly shaped spherical metal barrier explosion-proof and explosion-suppressing material.

[0016] Preferably, the width of the metal coil is 120-500 mm, and the thickness of the metal coil is 0.05-0.1 mm.

[0017] Preferably, the length L of the incision formed by the rolling cutter is 12 mm, the distance H1 between adjacent incisions is 6 mm, and the parallel distance H2 between the incisions is 2 mm.

[0018] Preferably, the expansion and pulling device is in an eight-shaped shape, and the metal material with the incision enters from the narrow end and is discharged from the wide end.

[0019] Preferably, the contact surface between the spin forming equipment and the three-dimensional polygonal mesh metal material is bowl-shaped, and the spinning pressure applied by the spin forming equipment causes the wound three-dimensional polygonal mesh metal material to be gradually pressed into a spherical shape.

[0020] Preferably, the diameter of the spherical metal barrier explosion-proof and explosion-suppression material is 30-100 mm.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The spherical metal barrier explosion-proof and explosion-suppression material prepared by the method has a diameter of 30-100 mm. Due to its regular shape and small volume, it is convenient to use machinery for filling operations, which greatly reduces the need for manual entry into the tank for filling operations and reduces the safety risks of operators;

[0023] The entire production process, from raw material pretreatment to the final product of spherical metal barrier explosion-proof and explosion-suppression materials, is closely connected between each step, with clear processes and easy operation and control. This optimized process not only improves production efficiency, but also ensures the stability and consistency of product quality.

[0024] The spherical metal barrier explosion-proof and explosion-suppression material prepared by the method can better disperse stress and reduce the degree of damage when subjected to external force impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Step 1: Raw material pretreatment

[0031] Select the metal coils that meet the requirements and flatten them through the rolling process to ensure the surface flatness and uniformity of the metal coils, providing a good foundation for subsequent processing;

[0032] Step 2: Rolling and forming

[0033] The metal coil pretreated in step 1 is subjected to rolling cutting, and parallel and staggered cuts are cut on the surface of the metal coil by selecting appropriate rolling cutting tools and process parameters to form a metal material with cuts;

[0034] Step 3: Expand and expand

[0035] The metal material with the cutout in step 2 is fed into an expansion and pulling device, and opened in a direction perpendicular to the cutout by mechanical force to form a three-dimensional polygonal mesh metal material;

[0036] Step 4: Slitting

[0037] The three-dimensional polygonal mesh metal material expanded and stretched in step 3 is sheared to cut it into multiple sections of three-dimensional polygonal mesh metal material having the same shape;

[0038] Step 5: Rolling and pressing into a ball shape

[0039] The three-dimensional polygonal mesh metal material obtained in step four is rolled together and then sent into the spinning forming equipment in sequence. Through the action of the mold and the spinning process, it is gradually pressed into a sphere to obtain an irregularly shaped spherical metal barrier explosion-proof and explosion-suppressing material.

[0040] Specifically, the width of the metal coil is 120 mm, and the thickness of the metal coil is 0.05 mm.

[0041] Specifically, the incision length L formed by the rolling cutter is 12 mm, the distance H1 between adjacent incisions is 6 mm, and the parallel distance H2 between the incisions is 2 mm (e.g. Figure 2 shown).

[0042] Specifically, the expansion and pulling device is in an eight-shaped shape, and the metal material with the incision enters from the narrow end and is output from the wide end.

[0043] Specifically, the contact surface between the spin forming device and the three-dimensional polygonal mesh metal material is bowl-shaped, and the spinning pressure applied by the spin forming device causes the wound three-dimensional polygonal mesh metal material to be gradually pressed into a spherical shape.

[0044] Specifically, the diameter of the spherical metal barrier explosion-proof and explosion-suppression material is 30 mm.

[0045] As can be seen from the above, this embodiment introduces an innovative method for making spherical metal barrier explosion-proof and explosion-suppressing materials; first, the metal coil is pre-treated by rolling to ensure that the surface of the material is flat and uniform, laying a solid foundation for subsequent steps; then, the rolling cutting technology is used to accurately cut parallel and staggered incisions on the metal coil to form a unique incision metal material; then, these materials are opened along the incisions by mechanical force in the expansion and pulling equipment and transformed into a mesh structure; after precise slitting, the three-dimensional polygonal mesh metal material is cut into multiple sections of the same shape; finally, these components are cleverly wound and sent to the spin forming equipment, and with the help of molds and spinning technology, they are gradually pressed into a perfect sphere.
