Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas cylinder manufacturing, and more specifically, it relates to a gas cylinder stamping device. Background Technology
[0002] With the increasing popularity of portable devices and the rise of outdoor activities, small handheld gas canisters are becoming increasingly popular as a convenient and efficient energy supply tool. These devices not only provide an immediate gas source for outdoor camping, bicycle inflation, and diving equipment inflation, but are also widely used in medical first aid and emergency rescue to provide users with oxygen supply in emergency situations.
[0003] During the manufacturing process of the gas tank, two covers are made and welded together at the openings of the covers to form the tank body. However, during the manufacturing process of the tank body, specifically when the circular plate material is extruded and shaped, whether multiple parts are formed at once or one part is formed at once, each part needs to be removed by workers after each part is formed, which greatly increases the labor intensity of the workers.
[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas cylinder stamping device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a base installed on a stamping bracket, two pillars fixedly connected to the upper end of the base, a connecting plate installed between the two pillars, a plurality of cylinder rods slidably connected to the connecting plate fixedly connected to the upper end of the base below the connecting plate, a plurality of fixing blocks fixedly connected to the side of the connecting plate, an upper mold fixedly connected to the lower end of the fixing blocks, a plurality of lower molds cooperating with the upper molds installed on the base, the bottom wall of the inner cavity of the lower molds being a spherical arc surface, and the bottom end of the upper molds being spherical.
[0007] By adopting the above technical solution, this device shapes the raw material sheet by installing several lower molds and upper molds on the base. The raw material sheet is placed on the lower mold, and the upper mold is moved downward by the connecting plate between the two pillars to press and shape it. The vertical movement of the connecting plate is controlled by a cylinder rod. The side wall of the connecting plate is connected to the upper mold by a fixed block. When the connecting plate moves downward, the upper mold presses and shapes the raw material sheet placed on the top of the lower mold. The raw material sheet is squeezed into the lower mold through the upper mold to form the required tank part.
[0008] Furthermore: the bottom wall of the lower mold cavity is a movable block that penetrates the lower mold. A connecting cylinder that penetrates the base is fixedly connected to the bottom of the lower mold. A connecting rod that abuts against the lower end of the movable block is slidably connected inside the connecting cylinder. The lower end of the connecting rod abuts against a pedal installed on the ground. A protrusion is rotatably connected to the bottom surface of the pedal. A base plate is fixedly connected to the bottom surface of the protrusion. When one end of the pedal is subjected to a downward force, the end of the pedal that is fixedly connected to the connecting cylinder rotates upward and drives the connecting rod to move upward.
[0009] By adopting the above technical solution, the can portion formed by the extrusion between the upper and lower molds is located inside the lower mold. After the upper mold moves upward, the can portion inside the lower mold is difficult to remove. Therefore, the bottom wall of the lower mold cavity is set as a movable block. The movable block moves vertically through a connecting rod fixedly connected to its lower end. The vertical movement distance is controlled by a pedal at the lower end of the connecting rod. The pedal, through the lever principle, presses one end of the pedal, generating a downward force, causing the end of the pedal that abuts against the connecting rod to rotate upward. The connecting rod then generates an upward pushing force on the movable block of the bottom wall of the lower mold cavity, pushing the can portion embedded in the lower mold upward.
[0010] Furthermore: a protruding strip is fixedly connected to the bottom of the base. The protruding strip is cross-shaped and has a through hole at its center.
[0011] By adopting the above technical solution, the protrusion is cross-shaped, which fixes the base part and increases the stability of the base when the upper mold is pressed down.
[0012] Furthermore, the protrusion at the lower end of the pedal is located near the connecting cylinder.
[0013] By adopting the above technical solution, the pedal part acts as a lever, making the pressing end a force-saving end, which can save more effort during demolding.
[0014] Furthermore: when the upper mold is embedded in the inner cavity of the lower mold, there is a gap between the upper mold column wall and the lower mold inner wall.
[0015] By adopting the above technical solution, a gap is left between the inner walls of the upper mold and the lower mold to allow for the retention of the raw material plate.
[0016] Furthermore, the connecting cylinder is a cross-shaped rod.
[0017] By adopting the above technical solution, the cross bar design can increase the stability of the connecting cylinder during operation and prevent the connecting cylinder from being deformed directly due to the impact of foreign objects caused by workers.
[0018] Furthermore, the position where the pedal abuts against the connecting rod is specifically a detachable abutment block.
[0019] By adopting the above technical solution, the structure of the abutting block (made of manganese, chromium alloy, etc.) and the connecting rod (made of manganese, chromium alloy, etc.) with better rigidity can greatly resist the impact force when the two abut. At the same time, by using its detachable connection method, it can be replaced when either part is damaged, ensuring the long-term use of the equipment and reducing maintenance costs.
[0020] In summary, this utility model has the following beneficial effects: by driving the connecting plate downward through the cylinder rod, the upper mold squeezes the raw material plate placed at the top of the lower mold downward, so that it enters the inner cavity of the lower mold to complete the shaping of the can. Then, by using the lever principle through the pedal, the can part in the inner cavity of the lower mold is pushed out, thereby realizing the demolding work. Multiple molding and demolding can be performed at once, which greatly increases the work efficiency and reduces the labor intensity of individuals. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0026] A gas cylinder stamping device, such as Figures 1 to 3As shown, the system includes a base 1 mounted on a stamping bracket. Two pillars 11 are fixedly connected to the upper end of the base 1, and a connecting plate 12 is installed between the two pillars 11. Several cylinder rods 121, slidably connected to the connecting plate 12, are fixedly connected to the upper end of the base 1 below the connecting plate 12. Several fixing blocks 122 are fixedly connected to the side of the connecting plate 12. An upper mold 14 is fixedly connected to the lower end of the fixing blocks 122. Several lower molds 13, which cooperate with the upper molds 14, are mounted on the base 1. The bottom wall of the inner cavity of the lower mold 13 is a spherical arc surface. The bottom end of the upper mold 14 is spherical. A movable block 4 penetrates the lower mold 13 through its inner cavity bottom wall. A connecting cylinder 2, penetrating the base 1, is fixedly connected to the bottom of the lower mold 13. The connecting cylinder 2 contains… A sliding connection is provided with a connecting rod 5 that abuts against the lower end of the movable block 4. The lower end of the connecting rod 5 abuts against a pedal 3 installed on the ground. A protrusion is rotatably connected to the bottom surface of the pedal 3, and a base plate is fixedly connected to the bottom surface of the protrusion. When one end of the pedal 3 is subjected to a downward force, the end of the pedal 3 that is fixedly connected to the connecting cylinder 2 rotates upward and drives the connecting rod 5 to move upward. A protrusion 15 is fixedly connected to the bottom of the base 1. The protrusion 15 is cross-shaped and has a through hole at its center. The protrusion at the lower end of the pedal 3 is located near the connecting cylinder 2. When the upper mold 14 is embedded in the inner cavity of the lower mold 13, there is a gap between the column wall of the upper mold 14 and the inner wall of the lower mold 13. The connecting cylinder 2 is a cross rod. The specific position where the pedal 3 abuts against the connecting rod 5 is a detachable abutment block.
[0027] The stamping bracket is specifically a support frame placed on the ground at a certain height and having a supporting function (it can be the support frame of publication number CN110271120B with appropriate modifications, and its main function is to support the present invention and support the various components on the base 1 of the present invention at a position away from the ground).
[0028] This device shapes raw material sheets by installing several lower molds 13 on a base 1. The raw material sheet is placed on the lower molds 13, and the upper mold 14 is moved downwards via a connecting plate 12 connected between two pillars 11 to press and shape it. The connecting plate 12 is controlled vertically by a cylinder rod 121. The connecting plate 12 can be powered and moved up and down by an external stroke mechanism: 1) via a hydraulic system and hydraulic pump, with the output shaft of the hydraulic pump connected to and driving the connecting plate 12; 2) via a double rocker arm structure to reciprocate up and down. The sidewall of the connecting plate 12 is connected to the upper mold 14 via a fixed block 122. When the connecting plate 12 moves downwards, it presses and shapes the raw material sheet placed at the top of the lower mold 13. A gap exists between the inner walls of the upper mold 14 and the lower mold 13, allowing the raw material sheet to be squeezed into the lower mold 13 through the upper mold 14, forming the desired can body. The can portion formed by the extrusion between the upper mold 14 and the lower mold 13 is located inside the lower mold 13. After the upper mold 14 moves upward, the can portion inside the lower mold 13 is difficult to remove. Therefore, the bottom wall of the inner cavity of the lower mold 13 is set as a movable block 4. The movable block 4 abuts against the connecting rod 5 inside the connecting cylinder 2. The connecting rod 5 is restricted by the connecting cylinder 2 and moves vertically. The connecting rod 5 abuts against the abutting block on the pedal 3, so that the vertical movement of the connecting rod 5 is controlled by the pedal 3 at the lower end of the connecting rod 5. The pedal 3 uses a lever structure. Pressing one end of it generates a downward force, causing the end of the pedal 3 that abuts against the connecting rod 5 to rotate upward. The cross rod design can increase the stability of the connecting cylinder 2 during operation. The protrusion at the lower end of the pedal 3 is located near the connecting cylinder 2. Through the lever principle, the pressing end is used as the force-saving end, which can save more effort during demolding. The connecting rod 5 generates an upward pushing force on the movable block 4 on the inner wall of the lower mold 13, causing the can portion embedded in the lower mold 13 to be pushed upward, completing the demolding.
[0029] A cross-shaped protrusion 15 is fixedly connected to the bottom of the base 1 to fix the part of the base 1 that is pressed, and to increase the stability of the base 1 when the upper mold 14 presses down.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
