Description

Technical Field

[0001] The invention belongs to the technical field of metal stamping forming equipment, and in particular relates to stamping forming equipment for a fuel motorcycle tank. Background Art

[0002] The oil tank is a container for fuel and a special container for storing hydraulic oil or hydraulic fluid in the hydraulic system. The oil tank can be divided into two types: open oil tank and closed oil tank. The oil tank must have a large enough volume; the oil suction pipe and the oil return pipe should be inserted below the lowest liquid level to prevent air bubbles from being generated by suction and oil return splashing; the distance between the oil suction pipe and the oil return pipe should be as far as possible, and a partition should be set between them. In order to keep the oil clean, the oil tank should have a peripheral sealed cover with an air filter installed on the cover; the bottom of the oil tank should be more than 150mm from the ground; full attention should be paid to the anti-corrosion treatment of the inner surface of the oil tank.

[0003] Compared with traditional machining, stamping technology saves materials and energy, is highly efficient, does not require high technical skills of operators, and can produce products that cannot be produced by machining through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through the mold, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be produced, which are widely used in various fields.

[0004] During the stamping process of the motorcycle fuel tank, it is necessary to use a pressing plate to stamp the top of the fuel tank to obtain the corresponding marking processing. However, since the top layer of the fuel tank is relatively thin and there is no corresponding support at the bottom of the top structure, it is easy to cause dents during the stamping process, which is not conducive to ensuring the stamping quality and also affects the molding effect of the product. At the same time, the existing stamping machines have relatively single functions, and the debris generated during the stamping process needs to be cleaned manually, which is not conducive to improving work efficiency.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) A limit stamping mechanism is set. After the dual-axis motor is started, it can drive the rotation of the first rotating tooth and the first lead screw at the same time. The first rotating tooth can enable the limit plates at both ends to clamp and limit the oil tank through the meshing transmission of the gears to prevent shaking during the stamping and marking process, thereby ensuring the safety of the stamping work of the device. During the rotation of the first lead screw, the first slider drives the pressure plate to stamp and mark the oil tank through the spiral transmission action, and the first slider can simultaneously drive the telescopic tube to move downward, thereby aligning the telescopic tube with the oil hole of the oil tank.

The annular groove of the rubber retaining ring can effectively resist and fit on the annular protrusion. Cooperating with the inner annular portion and the outer annular portion, the sealing of the rubber retaining ring at its oil hole can be effectively guaranteed. At the same time, the arc surface on the inner wall of the rubber retaining ring that is concave downward can further fit closely with the annular protrusion to prevent leakage during the inflation process. When the bending rod moves downward, the second gear plate can drive the third gear plate to move in the opposite direction through the second rotating tooth, and then the crossbeam drives the protective shell to move upward, so that the protective shell and the rubber retaining ring are separated. Similarly, when the bending rod moves upward, it means that the inflation work is no longer carried out, and the protective shell moves downward and fits on the rubber retaining ring, thereby producing a corresponding protective resistance effect on the outside of the rubber retaining ring and having a certain dustproof effect.

[0023] (3) A mobile adsorption mechanism is set. The mobile adsorption mechanisms on both sides of the limit stamping mechanism start the servo motor. Under the action of the spiral transmission, the adsorption assembly cooperates with the conical suction cup connected to the second air pump, so that the adsorption assembly can not only move and transport the oil tank, but also move the oil tank to the mold base, and automatically take out the formed oil tank. The overall structure is simple and easy to operate. The oil tank can be quickly loaded and unloaded with high accuracy, which effectively improves the processing efficiency and is highly practical. In addition, the second lead screw can drive the rotation of the first bevel gear during the rotation process. Under the action of mechanical transmission, it can drive the rotating drum on the rotating shaft at both ends to rotate, and then the cleaning brush can be used to synchronously clean the surface of the oil tank, thereby ensuring the cleanliness of the surface of the oil tank.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] Reference Manual Attached Figure 1 and attached Figure 3 As shown, the stamping forming equipment for fuel motorcycle tanks includes:

[0037] Bottom plate 1; limit punching mechanism 2, the limit punching mechanism 2 includes columns arranged around the bottom plate 1, the columns are fixedly connected by a panel 3, a double-axis motor 4 is fixedly installed at the center of the panel 3, one end of the output shaft of the double-axis motor 4 is connected to the first rotating tooth 5, and the other end is connected to the first lead screw 6, both ends of the outer wall of the first rotating tooth 5 are meshed with a first gear plate 7 that moves in the opposite direction, and one end of the first gear plate 7 extends through the panel 3 and extends to the limit plate 8;

[0038] The outer wall of the first lead screw 6 is spirally driven with a first slider 10 fixed on the pressure plate 9, one end of the outer wall of the first slider 10 is fixed on the bending rod 11, the upper and lower ends of the bending rod 11 extend to the second gear plate 13 and the telescopic tube 14 inside the cover body 12 respectively, the telescopic tube 14 is movably connected to the sleeve 15 at the bottom of the panel 3, the air inlet on the sleeve 15 is connected to the first air pump 16, and a downwardly recessed rubber retaining ring 17 is fixedly installed on the bottom end edge of the outer wall of the telescopic tube 14.

[0039] By extension, the first air pump 16 can also be inflated by manual pumping, for example, by continuously inflating using the principle of an air pump in the prior art, so as to increase the pressure inside the fuel tank. The specific working principle is as follows:

[0040] There is a gap between the piston and the wall of the air pump, and there is a concave rubber bowl on the piston. When the piston is pulled upward, the volume of air below the piston increases and the pressure decreases, and the air above the piston is squeezed from the rubber bowl to the bottom. When the piston is pressed downward, the volume of air below the piston decreases and the pressure increases, causing the rubber bowl to press tightly against the wall of the cylinder to prevent air from leaking above the piston.

[0041] A limit stamping mechanism 2 is set up. After the dual-axis motor 4 is started, it can drive the rotation of the first gear 5 and the first lead screw 6 at the same time. The first gear 5 can allow the limit plates 8 at both ends to clamp and limit the oil tank through the meshing transmission of the gears to prevent shaking during the stamping and marking process, thereby ensuring the safety of the stamping work of the device. During the rotation of the first lead screw 6, the first slider 10 drives the pressure plate 9 to stamp and mark the oil tank through the spiral transmission action, and the first slider 10 can simultaneously drive the telescopic tube 14 to move downward, so that the telescopic tube 14 is aligned with the oil hole of the oil tank. Under the action of the first air pump 16, the inside of the oil tank can be inflated. By increasing the internal pressure of the oil tank, the oil tank is not prone to surface depression during the stamping process, thereby ensuring the stability of the stamping work.

[0042] Specifically, the top of the cover body 12 is fixed to the bottom of the panel 3 by a bracket, and the second gear plate 13 is meshed with the third gear plate 19 that moves in the opposite direction through the second rotating teeth 18. The extension of the third gear plate 19 passes through the cover body 12 and is connected to the protective shell 21 through the cross beam 20. The protective shell 21 is hollow and has a movable opening 22 connected to the telescopic tube 14 at the center.

[0043] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The second gear plate 13 and the third gear plate 19 are connected with a slide groove along the height direction of the inner wall of the cover body 12. One end of the crossbeam 20 is connected to the protective shell 21 by plug-in installation. The first rotating tooth 5 and the first gear plate 7 are placed outside the top cover 23. An active cavity is formed between the first rotating tooth 5, the first gear plate 7 and the inner wall of the top cover 23. The outer wall of the top cover 23 is fixed to the panel 3 by a pull rod, and a strip groove connected to the first gear plate 7 is provided in the length direction of the panel 3.

[0044] Specifically, when the bending rod 11 moves downward, it can drive the telescopic tube 14 and the second gear plate 13 to move downward synchronously at the same time. During the downward movement of the telescopic tube 14, the air port can be aligned with the oil hole, so as to facilitate the subsequent inflation and pressurization work. During the downward movement of the second gear plate 13, the third gear plate 19 on the second rotating tooth 18 can drive the third gear plate 19 to move in the opposite direction, that is, the protective shell 21 on the cross beam 20 is driven to move upward through the third gear plate 19, so that the protective shell 21 and the rubber retaining ring 17 are separated, so that the rubber retaining ring 17 can effectively resist and limit the protrusion at the oil hole, thereby ensuring the sealing of the connection between the structural parts and preventing gas leakage during the inflation process.

[0045] refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9 The stamping forming equipment for the fuel motorcycle tank also includes a mobile adsorption mechanism 24 placed on both sides of the limit stamping mechanism 2, the mobile adsorption mechanism 24 includes a frame fixed at both ends of the bottom plate 1, a servo motor 25 is fixedly installed at one end of the frame, one end of the output shaft of the servo motor 25 passes through the frame and is connected to the second lead screw 26, and a second slider 28 fixed on the cylinder 27 is spirally driven on the outer wall of the second lead screw 26. The bottom of the piston rod on the cylinder 27 is connected to the lifting plate 29, and the lifting plate 29 is provided with an air guide pipe 31 connected to the second air pump 30. The bottom of the air guide pipe 31 is connected to a conical suction cup 32 adapted thereto, and the conical suction cup 32 is symmetrically arranged relative to the center of the lifting plate 29.

[0046] One end of the second lead screw 26 is connected to the first bevel gear 33 through a transmission shaft, the second lead screw 26 and the transmission shaft are connected by a coupling, and both ends of the outer wall of the first bevel gear 33 are meshed with bidirectional bevel gears 34, the outer wall of the bidirectional bevel gear 34 is meshed with a second bevel gear 36 fixed on the rotating shaft 35, the bottom of the rotating shaft 35 is connected to the rotating drum 37, the outer wall of the rotating drum 37 is connected to a ring-shaped cleaning brush 38 by a viscous fixation, a cleaning chamber connected to the oil tank is formed between the cleaning brushes 38, the horizontal central axis of the second lead screw 26 and the transmission shaft are maintained on the same axis, and the first bevel gear 33 is provided with a rolling groove placed on the side wall of the frame.

[0047] A retaining ring mechanism is provided. Since an annular protrusion is provided at the oil inlet of the oil tank, the telescopic tube 14 can drive the synchronous movement of the rubber retaining ring 17 during the downward movement. The annular groove 40 of the rubber retaining ring 17 can effectively resist and fit on the annular protrusion, and cooperate with the inner annular portion 41 and the outer annular portion 42, which can effectively ensure the sealing of the rubber retaining ring 17 at its oil hole. At the same time, the arc surface on the inner wall of the rubber retaining ring 17, which is concave downward, can further fit closely with the annular protrusion to prevent leakage during the inflation process. When the bending rod 11 moves downward, the second gear plate 13 can drive the third gear plate 19 to move in the opposite direction through the second rotating tooth 18, and then the crossbeam 20 drives the protective shell 21 to move upward, so that the protective shell 21 is separated from the rubber retaining ring 17. Similarly, when the bending rod 11 moves upward, it means that the inflation work is no longer carried out, and the protective shell 21 moves downward and fits on the rubber retaining ring 17, thereby producing a corresponding protective resistance effect on the outside of the rubber retaining ring 17 and having a certain dustproof effect.

[0048] Specifically, the second lead screw 26 cooperates with the adsorption assembly during rotation to achieve horizontal movement of the oil tank, and the second lead screw 26 can drive the first bevel gear 33 on the transmission shaft to rotate during rotation. Under the gear meshing transmission action, the power is reversed and adjusted, and the power can be transmitted to the rotating drum 37 on the second bevel gear 36, so that the cleaning brush 38 can effectively rotate and clean the surface of the oil tank during the rotation of the rotating drum 37. In addition, the bidirectional bevel gear 34 is not only symmetrically arranged, but also the transmission ratio between it and the second bevel gear 36 can be adaptively adjusted according to actual needs, and the sticky fixed cleaning brush 38 can facilitate the replacement and cleaning work of personnel, which is conducive to improving work efficiency and simplifying manpower.

[0049] The coupling arranged between the second lead screw 26 and the transmission shaft can ensure the effective and stable transmission of power, prevent the transmission parts from deviating from their positions during movement, and further affect the stable transmission of power. Moreover, when the second lead screw 26 drives the horizontal movement of the adsorption component under the action of spiral transmission, the servo motor 25 drives the adsorption component to move back and forth through forward and reverse movements. During the back and forth movement of the adsorption component, not only the removal and movement of the oil tank is completed, but also the resetting action of the adsorption component is completed. Moreover, the forward and reverse movements of the output shaft of the servo motor 25 can synchronously drive the rotation of the transmission shaft. In this way, under the action of gear meshing transmission, the cleaning brush 38 can be driven to rotate forward and reverse for cleaning, which greatly increases the cleaning effect on the surface of the oil tank.

[0050] A mobile adsorption mechanism 24 is set. The mobile adsorption mechanism 24 on both sides of the limit stamping mechanism 2 starts the servo motor 25. Under the action of spiral transmission, it cooperates with the conical suction cup 32 connected to the second air pump 30, so that the adsorption component can not only play a role in moving and conveying the oil tank, but also can move the oil tank to the mold base 39, and can automatically take out the formed oil tank. The overall structure is simple and easy to operate. The oil tank can be quickly loaded and unloaded with high accuracy, which effectively improves the processing efficiency and is highly practical. In addition, the second lead screw 26 can drive the rotation of the first bevel gear 33 during the rotation process. Under the action of mechanical transmission, it can drive the rotating drum 37 on the rotating shaft 35 at both ends to rotate, and then the cleaning brush 38 can be used to synchronously clean the surface of the oil tank, thereby ensuring the cleanliness of the surface of the oil tank.

[0051] Specifically, the first slider 10 and the pressure plate 9 are connected by a fixed rod, a shock-absorbing pad that contacts and fits with the pressure plate 9 is installed at the bottom of the first screw 6, and a mold base 39 placed on the base plate 1 is provided directly below the pressure plate 9. The transmission ratio between the second rotating tooth 18 and the second gear plate 13 remains the same as the transmission ratio between the second rotating tooth 18 and the third gear plate 19. A positioning hole is opened at the connection between the rubber retaining ring 17 and the telescopic tube 14 and they are connected by locking and fixing with a positioning pin.

[0052] An annular groove 40 is provided at the bottom edge of the rubber retaining ring 17 and is matched with the outer wall of the oil inlet on the oil tank. The two ends of the annular groove 40 are respectively integrally connected with an inner annular portion 41 and an outer annular portion 42. The air outlet of the telescopic tube 14 is docked on the oil inlet of the oil tank. Since the rubber retaining ring 17 has a certain elastic expansion and contraction function, and since the oil hole of the existing oil tank is provided with an annular protrusion, the inner annular portion 41 cooperates with the outer annular portion 42 to adaptively resist and fit the annular protrusion of a certain size, thereby ensuring the sealing of the connection between the structural parts, and it is also relatively simple when separated from the oil hole. The design is reasonable and the structural integration performance is strong.
