Description

Technical Field

[0001] This utility model relates to the field of metal button manufacturing technology, and in particular to a continuous stamping and blowing device for metal buttons. Background Technology

[0002] In the field of metal button manufacturing technology, continuous stamping production of metal buttons is an important link. In order to improve production efficiency, existing continuous stamping equipment for metal buttons can achieve a certain degree of automated production. These equipment usually use molds for stamping operations, and drive mechanisms such as hydraulic cylinders to drive the opening and closing of the punch and die, thereby stamping metal buttons out of the metal sheet.

[0003] Existing devices typically use manual labor or simple mechanical devices to remove buttons from the mold. However, manual removal is time-consuming and cannot meet the needs of large-scale production. Simple mechanical devices can easily damage the surface of the buttons during the removal process. This damage not only affects the appearance quality of the product but may also reduce its service life. Therefore, a continuous stamping and blowing device for metal buttons is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the time-consuming manual removal method, which cannot meet the needs of large-scale production, and the fact that simple mechanical devices can easily damage the surface of buttons during removal, which not only affects the appearance quality of the product but may also reduce its service life. Therefore, this invention proposes a continuous stamping and blowing device for metal buttons.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A continuous stamping and blowing device for metal buttons includes a device body, a hydraulic cylinder is fixedly installed on the top inner wall of the device body, and a stamping mechanism for continuously stamping metal buttons is provided at the bottom of the piston rod of the hydraulic cylinder.

[0007] The stamping mechanism includes a lower die base, which is fixedly connected to the bottom inner wall of the main body of the device. A plurality of limiting rods are fixedly connected to the top of the lower die base. The outer circumferential walls of the plurality of limiting rods are slidably connected to the same upper die base. The upper die base is fixedly connected to the bottom of the piston rod of the hydraulic cylinder. A punch is fixedly connected to the bottom center of the upper die base. A die is provided at the top center of the lower die base. The punch and the die are adapted to each other.

[0008] In one possible design, a mounting plate is fixedly connected to the top side of the lower die base. Multiple through-holes (or air jets) for blowing stamped metal buttons away from the die are provided at the bottom center of the die. A groove (or slide) is provided on the side of the mounting plate near the upper die base. An air storage chamber is provided inside the mounting plate. Multiple through-holes (or air jets) for blowing away the metal buttons from the die are provided on the side of the air storage chamber near the upper die base. The other ends of the multiple air jets (or air jets) are located within the groove (or slide). A groove (or slide) is provided at the bottom of the inner wall of the die. A closing mechanism is provided inside the groove (or groove) and the groove (or slide) (for sealing the air jets) during stamping.

[0009] In one possible design, the bottom of each of the multiple jet holes and one side of the gas storage chamber are fixedly connected to a gas pipe for providing high-pressure gas.

[0010] In one possible design, the closing mechanism includes a closing plate one and a closing plate two, which are slidably connected in slide groove one and slide groove two, respectively. The bottom of the lower mold base has an installation groove that communicates with slide groove one. A fixing plate is fixedly connected to the top inner wall of the installation groove. A connecting plate is fixedly connected to the side of the closing plate one near the fixing plate. The connecting plate is located within the installation groove. The same spring one is fixedly connected to the side of the connecting plate and the fixing plate that are close to each other. The same guide rod is rotatably connected to the inner walls of both sides of the installation groove. Two pull ropes are fixedly connected between the closing plate one and the closing plate two. The pull ropes pass around the guide rods and through the top inner wall of the installation groove. The fixing plate is located between the two pull ropes. A linkage mechanism for raising the closing plate two together with the upper mold base is fixedly provided on the side of the closing plate two near the upper mold base.

[0011] In one possible design, the linkage mechanism includes a connecting box, which is fixedly connected to the side of the enclosed plate two near the upper mold base. The same slider is slidably connected to the inner walls of both sides of the connecting box. The same spring two is fixedly connected between one side of the slider and one side of the inner wall of the connecting box. An inclined surface is provided on the top side of the slider. A locking groove is provided on the side of the upper mold base near the mounting plate. The slider is adapted to the locking groove. A reset mechanism is fixedly provided on the side of the mounting plate near the upper mold base. The reset mechanism is used to release the locking groove and the slider from engagement.

[0012] In one possible design, the reset mechanism includes two connecting rods, both of which are fixedly connected to the side of the mounting plate near the upper mold base. The two connecting rods are located on opposite sides of the slide groove. A common reset rod is fixedly connected to the side of the two connecting rods that are close to each other. The reset rod is adapted to the slider. The connecting box and the two connecting rods are located between the mounting plate and the upper mold base. The reset rod is located between the connecting box and the upper mold base.

[0013] Working Principle: In this application, when people need to use this device for continuous metal button stamping, the raw metal plate is first placed on the lower die base, and then the hydraulic cylinder is activated. The piston rod of the hydraulic cylinder will drive the upper die base to move downward along the limit rod, and then the punch at the bottom of the upper die base and the die at the top of the lower die base will stamp out the metal button on the metal plate. At the same time, the upper die base will push the slider along the connecting box inward through the inclined surface at the top of the slider until the second spring pushes the slider into the engagement groove through the elastic force. Then the piston rod of the hydraulic cylinder will drive the upper die base to move upward. Then the upper die base will drive the slider to move upward through the engagement groove with the slider. Then the slider will drive the second closing plate to move upward through the connecting box. Then the second closing plate will drive the connecting plate to move through the pull rope, and then drive the first closing plate to move. During the movement of the first and second sealing plates, the previously closed air vents one and two will open. High-pressure gas will then be ejected outward through air vents one and two. The high-pressure gas ejected from air vent one will eject the metal button inside the die cavity. Then, the high-pressure gas ejected from air vent two will blow the metal button that has left the die cavity out of the device. When the upper die holder moves the sealing plate two to a certain height, the inclined surface of the slider will contact the reset rod. Then, the reset rod will push the slider inward through the inclined surface at the top of the slider until the slider disengages from the locking groove. Then, spring one will push the connecting plate to move under the elastic force. Then, the connecting plate will move the sealing plate one to close air vent one. At the same time, the connecting plate will move the sealing plate two downward through the pull rope and close air vent two. Then, the metal plate can be moved to start the next stamping.

[0014] Beneficial effects: In this utility model, the continuous stamping and blowing device for metal buttons uses a hydraulic cylinder as a power source. The reciprocating motion of its piston rod drives the upper die seat in the stamping mechanism to move up and down along the limit rod, and cooperates with the lower die seat to complete the stamping operation of metal buttons. This design is not only simple in structure and stable in operation, but also enables continuous and efficient stamping of metal buttons, which greatly improves production efficiency.

[0015] In this utility model, a continuous stamping and blowing device for metal buttons is provided. By opening air jet hole one and air jet hole two on the lower die base and the mounting plate respectively, and connecting them to a high-pressure air source through an air pipe, the device utilizes a sealing mechanism to effectively seal the air jet holes during the stamping process. This can prevent high-pressure gas from interfering with the stamping operation. After the stamping is completed, the upper die base rises and drives the sealing mechanism to move, opening the air jet holes. The high-pressure gas is then ejected, blowing the metal button out of the die cavity and blowing it away from the device through air jet hole two. This process does not require manual intervention, which not only realizes the automatic blowing out of the metal button, but also avoids the damage to the button surface in the traditional removal method, thus ensuring product quality.

[0016] In this utility model, the continuous stamping and blowing device for metal buttons, through the setting of a linkage mechanism, uses the linkage mechanism to cooperate with the upper die base when it rises, driving the second and first sealing plates to move, which can precisely control the opening and closing of the air jet. When the upper die base rises to a certain height, the reset mechanism will disengage the slider from the locking groove, and the spring will then push the connecting plate and the sealing plate to reset, closing the air jet. This design not only achieves precise control of the air jet, but also ensures the stability and reliability of the device in continuous stamping operations, avoiding malfunctions and safety hazards caused by the inability to close the air jet in time.

[0017] In this invention, a hydraulic cylinder can be used as a power source. The reciprocating motion of its piston rod drives the upper die holder in the stamping mechanism to move up and down along the limiting rod, cooperating with the lower die holder to complete the stamping operation of the metal button. This design is not only simple in structure and stable in operation, but also enables continuous and efficient stamping of metal buttons, greatly improving production efficiency. It prevents high-pressure gas from interfering with the stamping operation. Simultaneously, after stamping is completed, the upper die holder rises, driving the closing mechanism to move and opening the air vent. High-pressure gas is then ejected, blowing the metal button out of the die cavity and away from the device through the second air vent. This process requires no manual intervention, not only automatically blowing out metal buttons but also avoiding damage to the button surface caused by traditional removal methods, thus ensuring product quality. It also allows for precise control of the opening and closing of the air jet. When the upper mold base rises to a certain height, the reset mechanism will disengage the slider from the locking groove, and the spring will then push the connecting plate and the sealing plate to reset, closing the air jet. This design not only achieves precise control of the air jet but also ensures the stability and reliability of the device in continuous stamping operations, avoiding malfunctions and safety hazards caused by the inability to close the air jet in time.
