Description

Technical Field

[0001] This invention relates to the field of arc processing equipment, and more particularly to an arc forming machine for processing civil defense equipment. Background Technology

[0002] Civil defense facilities are important facilities for preventing enemy air raids, effectively sheltering personnel and materials, preserving war potential, and providing engineering support for persisting in the struggle against urban air raids.

[0003] 1. Sealed Facilities – These mainly consist of protective doors, airtight doors, and gas-proof passages. Their function is to prevent contaminated air from entering the interior of the facility. Protective airtight doors and gas-proof doors also offer some protection against the shock waves generated by nuclear explosions, missile explosions, bomb explosions, etc. 2. Civil defense ventilation equipment - automatic overpressure exhaust valve, oil filter dust collector, electric foot pedal dual-purpose fan, explosion-proof overpressure exhaust valve, etc.

[0004] 3. Decontamination facilities – including decontamination rooms, disinfectants, and decontamination materials. Used for partial or full-body decontamination of personnel entering the facility to prevent them from bringing toxic agents into the air-raid shelter and to ensure the safety of those inside. 4. Ventilation and Air Filtering Facilities – These mainly consist of dust filters, gas filters, fans, and ductwork. The dust filters and gas filters respectively remove smoke, toxic mist, and adsorb toxic agent vapors. The filtered air is then delivered into the civil defense facility through ductwork.

[0005] 5. Civil defense control equipment – ​​civil defense sealed boxes, civil defense explosion-proof call / call buttons, ventilation mode signal control boxes, ventilation mode signal light boxes, etc.

[0006] Existing arc forming machines for processing civil defense equipment generally require the continuous disassembly and installation of forming molds according to the size of the arc to be formed, which consumes a lot of manpower and material resources and reduces work efficiency. To address these issues, we propose an arc forming machine for processing civil defense equipment. Summary of the Invention

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-3 A curved forming machine for processing civil defense equipment includes a machine base 1, a hydraulic push rod 5 fixed on the machine base 1, and an adjustment mechanism 9 fixed to the piston rod end of the hydraulic push rod 5; The adjusting mechanism 9 includes a U-shaped frame 91 fixed to the end of the piston rod of the hydraulic push rod 5. A fixed shaft 92 is fixed inside the U-shaped frame 91. Multiple semi-circular forming plates 93 with different radii and multiple arc forming plates 910 with different curvatures are rotatably mounted on the fixed shaft 92. An adjusting block 96 is rotatably mounted on the fixed shaft 92. A second insertion pipe 97 is symmetrically arranged on the adjusting block 96. A reinforcing block 94 is fixed on the inner side of both the semi-circular forming plate 93 and the arc forming plate 910. A first insertion pipe 95 is symmetrically fixed on the reinforcing block 94. A connecting rod 98 is movably inserted between the first insertion pipe 95 and the second insertion pipe 97.

[0021] A limiting tube 99 is fixed inside the U-shaped frame 91. One end of the connecting rod 98 is located inside the limiting tube 99, and the other end of the limiting tube 99 is connected to a locking nut via a thread. A boss 4 is fixed on the upper side of the base 1, and two support wheels 3 are rotatably mounted on the boss 4. Pre-fixing components 2 are installed on the sides of the U-shaped frame 91. The pre-fixing components 2 include a return spring 22 fixed to the side of the U-shaped frame 91. A push rod 23 is provided inside the return spring 22. A sleeve 21 is provided on the side of the push rod 23 near the cylinder opening. A push plate 6 is fixed on the other side of the sleeve 21. The upper and lower ends of the reinforcing block 94 are both arc-shaped. The width of the reinforcing block 94 is smaller than the longitudinal width of the semi-circular forming plate 93 and the arc-shaped forming plate 910, so that the semi-circular forming plate 93 and the arc-shaped forming plate 910 can rotate normally. The semi-circular forming plate 93 and the arc-shaped forming plate 910 are arranged alternately according to the arc and radius, which increases the number of semi-circular forming plates 93 and arc-shaped forming plates 910. The hydraulic push rod 5 is electrically connected to the external power supply and external control equipment.

[0022] Working Principle: Existing arc forming machines for processing civil defense equipment generally require the continuous disassembly and installation of forming molds according to the size of the arc, which consumes a lot of manpower and material resources and reduces work efficiency. In this embodiment, the plate to be processed into an arc shape is placed on the boss 4, and the corresponding semi-circular forming plate 93 or arc forming plate 910 is rotated to the side close to the plate according to the required arc. Then, the reinforcing block 94, the second insertion pipe 97 and the limiting pipe 99 are connected in series by the connecting rod 98 and fixed by the locking nut, thereby keeping the semi-circular forming plate 93 or arc forming plate 910 in a horizontal state. Then, the hydraulic push rod 5 is connected to the power supply, and the hydraulic push rod 5 works to make the push plate 6 first contact the plate. The material comes into contact with the material, thereby fixing the sheet metal and preventing displacement during processing. As the hydraulic push rod 5 operates, the corresponding semi-circular forming plate 93 or arc forming plate 910 comes into contact with the sheet metal and presses it to the corresponding curvature. At the same time, during the extrusion process, the semi-circular forming plate 93 and the arc forming plate 910, under the superposition effect of the reinforcing block 94, can effectively increase the connection strength between the semi-circular forming plate 93 or the arc forming plate 910, preventing deformation of the semi-circular forming plate 93 or the arc forming plate 910 during the extrusion process. Through the rotation setting between the semi-circular forming plate 93 and the arc forming plate 910 and the fixed shaft 92, the required curvature can be quickly switched, improving processing efficiency.
