Description

Technical Field

[0001] This invention belongs to the field of fire extinguisher bottle manufacturing technology, and particularly relates to a fire extinguisher bottle manufacturing equipment. Background Technology

[0002] A fire extinguisher bottle is a portable fire extinguishing tool, which is composed of three parts: the bottle body, the cap, and the bottom, which are welded together. In the production of fire extinguisher bottles, the bottle body, the cap, and the bottom are usually processed separately, and then the three parts are assembled and welded together to form a fire extinguisher bottle. Argon arc welding is usually used for welding during the welding process.

[0003] When welding fire extinguisher cylinders, the steel plate must first be rolled into a cylinder and its longitudinal seam welded. Then, the cylinder with the longitudinal seam welded must be transferred to a station dedicated to welding the circumferential seam between the cylinder body and the bottom. After this welding is completed, the assembly must be hoisted to another device dedicated to welding the circumferential seam between the cylinder body and the cap for final welding. Only then is the welding process of the entire cylinder completed. This process involves multiple workpiece handling and positioning, which is cumbersome and not only significantly reduces production efficiency but also increases the accumulation of errors due to multiple clamping, seriously affecting the stability of the production process and the reliability of the product.

[0004] To address these issues, we propose a fire extinguisher bottle manufacturing equipment. Summary of the Invention

Furthermore, the tilt angle of the third clamp can be adjusted according to the tilt angle of the cap's outer wall, facilitating stable fixation of the cap and greatly improving the welding production efficiency and reliability of the fire extinguisher cylinder.

This avoids transferring the cylinder body with the longitudinal seam welded to a station dedicated to welding the circumferential seam between the cylinder body and the bottom, and then hoisting the components to another station dedicated to welding the circumferential seam between the cylinder body and the cap, which would reduce production efficiency and increase the accumulation of errors due to multiple clamping.

An eleventh electric telescopic rod 710 is fixedly connected to the rod wall of the round rod 78. A third clamping plate 711 is fixedly connected to the telescopic end of the eleventh electric telescopic rod 710.

[0035] Specifically, the tilt angle of the third clamping plate 711 can be adjusted according to the tilt angle of the outer wall of the bottle cap, which facilitates the stable fixing of the bottle cap and greatly improves the welding production efficiency and reliability of the fire extinguisher bottle.

[0036] The operating principle of the present invention is now described as follows:

[0037] In this invention, when welding is required for the fire extinguisher bottle body, the worker first places the bottle bottom on the vacuum suction cup 32, then controls the vacuum suction cup 32 to start, using the vacuum suction cup 32 to adhere and fix the bottle bottom. Next, the worker places the rolled steel plate above the bottle bottom, then controls the first slide rail 33 to start, driving the two first sliding plates 34 to start. After both support plates 411 have moved to the farthest end of the longitudinal straight seam of the rolled steel plate and the two support plates 411 are aligned, the first slide rail 33 is closed. Then, the eighth electric telescopic rod 412 is started, driving the second clamping plate 413 to move, using the second clamping plate 413 to fix the bottle body. Finally, the third motor 79 is started, driving the corresponding round rod 78 to rotate. During the rotation of the corresponding round rod 78, the eleventh electric telescopic rod 710 and the third clamping plate 711 will rotate. After the tilt angle of the third clamping plate 711 is the same as the tilt angle of the corresponding bottle cap outer wall, the third motor 79 is controlled to close. Then, the staff puts the bottle cap into the fixing plate 76, and then the eleventh electric telescopic rod 710 is started, driving the third clamping plate 711 to move. The third clamping plate 711 is used to fix the outer wall of the bottle cap. Then, the second electric telescopic rod 41 and the third electric telescopic rod 43 are continuously started, causing the connecting plate 47 to move into the bottle body. Then, the second motor 46 is started, driving the corresponding connecting plate 47 to rotate. During the rotation of the connecting plate 47, the first clamping plate 49 will rotate. After rotating to the side corresponding to the second clamping plate 413 and aligning the first welding torch 57 with the longitudinal seam of the bottle, the second motor 46 is shut off. Then, the third electric telescopic rod 43 is activated, moving the first clamping plate 49 to fix the outer wall of the bottle. At this point, the first clamping plate 49 and the corresponding second clamping plate 413 are in the same position fixing the bottle. Next, the sixth electric telescopic rod 56 is activated, moving the first welding torch 57 closer to the longitudinal seam inside the bottle. The first welding torch 57 is used to weld the longitudinal seam. During welding, the first spray gun 59 is activated, extracting argon gas from the first connecting ring 58 and spraying it onto the welding point of the longitudinal seam using the first welding torch 57, preventing oxidation of the weld at high temperatures. Then, the second slide rail 52 is activated, driving the first welding gun 57 to weld other positions of the longitudinal straight seam. After the second slide plate 53 moves to the bottom, the fifth electric telescopic rod 54 is activated, driving the first welding gun 57 to continue moving downwards, thus completing the welding of the entire longitudinal straight seam. After welding is completed, the first clamping plate 49 and the first welding gun 57 are restored to their original positions. Then, the ninth electric telescopic rod 71 is activated, driving the connecting frame 72 to move above the bottle body. Then, the fourth motor 73 is activated, driving the connecting block 74 to rotate, causing the fixing plate 76 and the bottle cap to move to the corresponding side of the bottle body. Finally, the tenth electric telescopic rod 75 is activated, driving the fixing plate 76 and the bottle cap to move, causing the bottle cap to move directly above the corresponding bottle body.Then, control the ninth electric telescopic rod 71 to retract, bringing the bottle cap into contact with the bottle body. Next, control the first electric telescopic rod 31 to activate, moving the corresponding bottle bottom to contact the bottle body. Then, control the third slide rail 62 to activate, moving the third sliding plate 63, causing the fixing rod 64 to move the mounting ring 65 downwards, moving the second welding torch 69 to the side where the bottle bottom contacts the bottle body. Then, control the twelfth electric telescopic rod 68 to activate, moving the second welding torch 69 to the position where the bottle bottom contacts the bottle body. Then, use the second welding torch 69 to weld the contact area. During welding, control the second spray gun 611 to activate, spraying argon gas from the second connecting ring 610 towards the welding area. Simultaneously, control the fourth slide rail 66 to activate, using the fourth sliding plate 67 to move the second welding torch 69, facilitating the complete welding of the connection between the bottle bottom and the bottle body. Then, proceed according to... The above steps, involving welding the connection between the bottle bottom and the bottle cap, complete the production of the fire extinguisher bottle body. This allows for the direct, individual fixing of the bottle body, cap, and bottom during the production process. After the longitudinal seam welding within the bottle body is completed, the connections between the bottle body and cap, and between the bottle body and bottom, are welded directly. This avoids the need to transfer the bottle body with the longitudinal seam welded to a dedicated station for circumferential seam welding between the bottle body and bottom, and then re-lift the assembly to another dedicated device for circumferential seam welding, which reduces production efficiency and increases error accumulation due to multiple clamping operations. Furthermore, the tilt angle of the third clamping plate 711 can be adjusted according to the tilt angle of the cap's outer wall, facilitating stable cap fixing and significantly improving the welding efficiency and reliability of the fire extinguisher bottle body.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
