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 work are within the scope of protection of the present invention.

[0022] The utility model provides a technical solution: a metal mesh welding device, characterized in that it includes a lower frame 1, a mold bracket 2 fixed in the lower frame 1, a forming device 3 installed above the mold bracket 2, an adjustment motor 4 installed in the lower frame 1, a pulley 6 fixed on the side of the forming device 3, a belt 5 connecting the adjustment motor 4 and the pulley, a first hydraulic rod 7 installed on the side of the lower frame 1, a hydraulic valve 11 fixed on the outside of the first hydraulic rod 7, a welding device 12 fixed on the inside of the hydraulic valve 11, an upper bracket 10 fixed on the upper side of the lower frame, a second hydraulic rod 9 fixed below the upper bracket 10 and a translation bracket 8 fixed below the second hydraulic rod 9; the mold bracket 2 is fixed on the lower bracket 1, and the mold bracket has a certain height for reserving installation space for the adjustment motor 4 below; the forming device 2 is installed above the mold bracket 2 for performing the first molding of the metal mesh so that the middle part of the metal mesh is bent downward into a circle; the adjustment motor 4 is installed in the lower frame 1 to provide adjustment power for the forming device 3 so that the forming device 3 can adapt to metal meshes of different sizes and be fixed. The pulley 6 and belt 5 on the side of the forming device 3 are used to transmit power from the adjustment motor 4. The first hydraulic rod 7 is fixed to the side of the lower frame 1 and can slide up and down along the slot on the side of the lower frame 1 and be locked. It is used to push the welding device 12 to achieve secondary forming and welding of the metal mesh. The hydraulic valve 11 fixed on the outside of the first hydraulic rod 7 is used to adjust the pressure of the hydraulic rod 7. The welding device 12 is fixed to the first hydraulic rod 7 with bolts. The metal mesh can be welded end to end after secondary forming. The upper bracket 10 is connected to the lower bracket 1 with bolts to fix the second hydraulic rod 9 and withstand the pressure during the first forming of the wire mesh. The second hydraulic rod 9 is fixed to the upper bracket 10 with four bolts to provide pressure for the forming device 3 during the first forming of the metal mesh. The two ends of the translation bracket 8 are fixed to the slideway of the lower bracket 1 to prevent excessive offset when sliding up and down, making the displacement smooth and fluent. The second hydraulic rod 9 is connected to the upper middle part and the forming device 3 is connected to the side. The pressure of the second hydraulic rod 9 is transmitted to the forming device 3 for the first forming of the metal mesh.

[0023] The molding device includes a molding lower mold 301 symmetrically arranged above the mold support 2, a first screw rod 302 installed in the molding lower mold 301, a second screw rod 307 fixed to the side of the translation support 8, a first adjustment block 304 installed on the second screw rod 307, a second adjustment block 305 installed on the second screw rod 307, a tension spring 303 circumferentially installed on the second screw rod 307, and a support sheet 306 installed on one side of the tension spring 303; the lower mold 301 is symmetrically arranged by two identical molds on the left and right, which can convert the circular motion of the first screw rod 302 into linear motion and adjust the opening and closing size of the lower mold 301 To adapt to the forming requirements of metal meshes of different sizes, the second screw rod 307 is fixed to the side of the translation bracket 8 to transmit the pressure of the second hydraulic rod 9. The first adjusting block 304 and the second adjusting block 305 are installed on both sides of the second screw rod 307. When the adjusting blocks are away from each other, the gap between the outer support pieces 306 can be enlarged to adapt to the forming of metal meshes of different circumferential sizes. The tension spring 303 is circumferentially installed in the middle of the second screw rod 307. There is a tension spring 303 in the middle of each support piece 306. The tension spring pulls the support piece 303 inward and firmly supports it on the two adjusting blocks, making the entire structure more stable.

[0024] The first adjustment block 304 has a cylindrical shape of r=3 cm on the outside and a truncated cone shape on the inside. The connection between the truncated cone and the cylinder is r=3 cm on one side and r=6 cm on the other side. The height of the truncated cone is 20 cm. The first adjustment block is not only used to adjust the gap between the outer support piece 303, but also used to cantilever the support piece 306 and its internal structure. The outer cylinder plays a supporting role, so that the entire structure will not be deformed when the metal mesh is first formed.

[0025] The second adjustment block 305 is a truncated cone with an outer side r=3 cm, an inner side r=6 cm, and a height of 20 cm. The second adjustment block 305 cooperates with the first adjustment block 304 so that the size of the circle formed by the support plate 303 can be freely adjusted from r=3 cm to r=6 cm.

[0026] a third adjusting block 3061 is fixed to the inner side of the support piece 306; when the two inner adjusting blocks move away from each other, the third adjusting block 3061 will push against the position with the larger radius of the two inner adjusting blocks, lifting the support piece 306 and increasing the size of the circle formed by the support piece.

[0027] The second adjustment block 3061 is triangular, and the slope of its inner angle is 0.5, with a 1 / 4 circle notch of r = 3.5 cm at the bottom; the slope of the inner angle is greater than the slope of the two internal adjustment block cones to prevent adjustment failure. The 1 / 4 circle notch of 3.5 cm can lock the two adjustment blocks under the action of the tension spring 303, making the support plate 306 more stable.

[0028] The middle part of the welding device 12 is a nylon pressing block 1201, inside of which is a titanium alloy welding rod 1202; the nylon pressing block has a certain elasticity and is non-conductive, which prevents leakage when the welding rod 1202 is energized, making welding more efficient.

[0029] Working principle:

[0030] During operation, by starting the motor, adjusting the gap of the forming lower die 301, adjusting the width above the forming lower die 301 to the diameter of the metal mesh to be formed, and then adjusting the outer support plate 306 to the gap with the lower forming die 301 by rotating the first adjusting block 304 and the second adjusting block 305 until the gap is the thickness of the metal mesh, raising the second hydraulic rod 9, placing the metal mesh on the lower forming die 301, and starting the equipment, first the second hydraulic rod 9 will drive the support plate 306 to press down through the second screw rod 307 and the first adjusting block 304, forming the middle of the metal mesh into a semicircle, at this time the two ends of the metal mesh will be tilted upward, at this time the two first hydraulic rods 7 will push the two welding devices 12 together to form the upper end of the metal mesh, and then the welding strip 1202 of the welding device 12 is energized to form a circuit with the entire frame to weld the formed metal mesh end to end, and after welding is completed, the first hydraulic rod 7 drives the welding device 12 to contract, and the second hydraulic rod 9 contracts to take out the formed metal mesh.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
