Description

Technical Field

[0001] The invention relates to the technical field of furnace component processing, in particular to a stamping mechanism based on a cassette furnace component. Background Art

[0002] A cartridge stove refers to a non-fixed household kitchen appliance, hotel supplies, and outdoor leisure supplies that uses butane gas as the main fuel, and liquefied gas and other gases can also be used as fuel for direct fire heating. A cartridge stove is also called a portable butane gas stove; a portable barbecue stove is a type of kitchen appliance that has just emerged in recent years and is mostly used for household outdoor leisure and hotel supplies. According to the appearance, it is mainly divided into single-burner, double-burner, mini and ultra-thin, and single-use and dual-use cartridge stoves. A cartridge stove is generally composed of a base shell, a switch, a bracket, a burner, a heat pipe and other components. The base shell is also composed of multiple components that are stamped and processed together.

[0003] Among them, the panel welded to the bracket in the base shell of the cassette stove needs to go through two stamping processes before assembly. The first is to stamp the panel downward to create a recessed area, and the second is to punch a slot hole at the center of the recessed area for the exposed fire point. The existing stamping mechanism adopts a step-by-step stamping method for the cassette stove assembly. The recessed stamping is performed first and then the punching is performed, which results in the need for secondary transportation of the panel assembly, increasing the overall time of the stamping process. At the same time, due to the particularity of the recessed stamping of the panel, the panel will be stuck in the stamping groove after stamping and is difficult to unload. The panel needs to be pushed out of the stamping groove before it can be unloaded. The traditional solution is to set a movable part that can be pushed upward at the bottom of the stamping groove, and use power to control the movable part to eject the panel. However, the method of designing a movable part in the groove cannot avoid the indentation of the panel caused by the movable part during stamping. In view of this, we propose a stamping mechanism based on the cassette stove assembly. Summary of the invention

[0029] 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.

[0030] See also Figure 1-Figure 7 As shown, the technical solution provided by the present invention is:

[0031] A stamping mechanism based on a cassette stove assembly includes a stamping base 1, the top of the stamping base 1 is connected to a mounting base 2, the mounting base 2 is provided with a power control device 3 for providing stamping power, performing recessed stamping on the cassette stove panel assembly, and performing punching after stamping, a stamping groove 4 is provided on the top of the stamping base 1; a secondary stamping device 5 is used to stamp the panel assembly twice to complete the overall stamping work; an automatic lifting device 6 is used to eject the panel assembly after stamping in the stamping groove 4.

[0032] In this embodiment, the secondary stamping device 5 includes a stamping main rod 51, the surface of the stamping main rod 51 is fixedly connected to the power control device 3, the surface of the stamping main rod 51 is elastically connected to the clamping base 52 through a spring, and the bottom of the clamping base 52 is fixedly connected to a recessed stamping head 53, and the recessed stamping head 53 is used to perform a section of stamping on the panel assembly so that the central area of ​​the panel assembly is recessed downward. The inside of the clamping base 52 is slidably connected to a metal clamping block 54, and the end of the stamping main rod 51 is magnetically connected to a punching head 55. The clamping base 52 is inserted and fixedly connected to the punching head 55 through the metal clamping block 54, so that the stamping main rod 51 can achieve the effect of driving the recessed stamping head 53 on the clamping base 52 to punch downward while driving the punching head 55 to punch downward, and a trigger device 56 is arranged inside the clamping base 52. A magnetic sleeve 57 is fixedly connected to the surface of the stamping main rod 51, and the bottom end of the stamping main rod 51 is fixedly connected to the end of the punching head 55. The surface of the punching head 55 is movably connected to the inside of the recessed stamping head 53. A socket 58 is provided inside the magnetic sleeve 57. Both the magnetic sleeve 57 and the socket 58 are provided with magnetic force for magnetically adsorbing the metal card block 54. The stamping main rod 51 and the clamping base 52 are stably fixed by the suction force and the plugging force of the card block inserted into the socket 58. The magnetic force at the magnetic sleeve 57 is smaller than the magnetic force of the strong magnetic plate 561. The end of the metal card block 54 is plugged into the inside of the socket 58. By setting a secondary stamping device 5, two stamping heads are used for combined stamping to achieve the effect of secondary stamping of a panel component in a split manner, thereby avoiding the problem that the panel component needs to be moved to the bottom of two stamping machines for two-stage stamping, thereby improving the efficiency of the stamping process and avoiding the problem of space waste caused by two stamping machines.

[0033] Furthermore, the trigger device 56 includes a strong magnetic plate 561, the surface of the strong magnetic plate 561 is slidably connected to the inside of the clamping base 52, the bottom of the strong magnetic plate 561 is fixedly connected to a ring seat 562, the surface of the ring seat 562 is fixedly connected to a rubber column 563, and the end of the rubber column 563 is fixedly connected to the surface of the clamping base 52. By setting the trigger device 56, the clamping base 52 and the stamping main rod 51 are automatically triggered to separate according to the stamping height of the stamping main rod 51, thereby realizing the automatic separation of the two stamping heads, thereby facilitating the secondary stamping of the punching head 55 after the separation.

[0034] Furthermore, the power control device 3 includes an active motor 31 and an automatic clamping device 37. The surface of the active motor 31 is fixedly connected to the surface of the mounting seat 2. The output shaft of the active motor 31 is clamped with a roller rod 32. The surface of the roller rod 32 is fixedly connected to a driving gear 33. The surface of the driving gear 33 is meshed with a connecting gear 34. Figure 5 As shown in , the surface of the driving gear 33 is provided with two groups of symmetrically distributed teeth, which are divided into one section of teeth and two sections of teeth. In the initial state, the center of the one section of teeth is in contact and meshing with the connecting gear 34. When the driving gear 33 rotates, the connecting gear 34 is driven by the one section of teeth for ninety degrees and then loses the meshing effect. The driving gear 33 continues to rotate without driving the connecting gear 34 to rotate until the two sections of teeth contact the connecting gear 34. When the complete two sections of teeth contact the connecting gear 34, it will drive it to rotate 180 degrees. The interior of the connecting gear 34 is fixedly connected to a connecting crankshaft 35, and the end of the connecting crankshaft 35 is slidably connected to a limited position stamping frame 36. The initial state of the connecting crankshaft 35 is as shown in FIG. Figure 5 As shown in , it is in the upward stage, at which time the limit stamping frame 36 is at the highest position. When the driving gear 33 first drives the connecting gear 34 to rotate 90 degrees through half of the teeth, the connecting gear 34 drives the limit stamping frame 36 to move downward to the first stamping position through the linked crankshaft 35 until the second teeth contact the connecting gear 34 to rotate it to 180 degrees and then to 270 degrees. During the 180-degree rotation, the crankshaft passes through the stamping frame for two-stage stamping. During the 270-degree rotation, the crankshaft passes through the stamping frame for two-stage stamping and resets after the two-stage stamping. The surface of the roller rod 32 is connected to the connecting roller 38 through a belt drive, as shown in FIG. Figure 1 As shown, two roller rods 32, driving gears 33 and other structures are connected to the crankshaft 35, which are symmetrically distributed on both sides of the stamping main rod 51. The connecting roller 38 is combined with a belt to drive the roller rods 32 on both sides to rotate synchronously, thereby realizing the synchronous provision of stamping power to both sides of the stamping main rod 51, so as to achieve the effect of stamping the stamping main rod 51 downward, and the surfaces of the roller rod 32 and the connecting roller 38 are respectively rotated to connect the inside of the mounting seat 2, and the end of the connecting gear 34 is rotated to connect the inside of the mounting seat 2, and the limit stamping frame 36 is The two sides are respectively slidably connected to the inner wall of the mounting seat 2, and protrusions are provided on both sides of the limit punching frame 36. The limit sliding of the protrusions in the grooves is utilized to realize the limit sliding of the limit punching frame 36, so that it can only perform up and down linear motion. At the same time, a transverse sliding groove is provided at the sliding part of the limit punching frame 36 at the end of the linked crankshaft 35, which is used to limit the sliding trajectory of the crankshaft, and then the rotating crankshaft drives the limit punching frame to perform up and down linear motion, so as to achieve the purpose of up and down stamping. The surface of the limit punching frame 36 is fixedly connected to the surface of the stamping main rod 51.

[0035] It is worth noting that the automatic clamping device 37 includes a limit turntable 371, a swing connecting plate 376 and an extrusion rod 377. One end of the limit turntable 371 is rotatably connected to the inside of the stamping base 1, and the other end of the limit turntable 371 is fixedly connected to a swing block 372. A limit slide groove 373 is provided inside the limit turntable 371, and the inner wall of the limit slide groove 373 is slidably connected to a limit rod 374. The end of the limit rod 374 is fixedly connected to a sliding clamp 375. The number of the limit slide grooves 373 and the corresponding structures thereat are both set to three. This design scheme is aimed at the stamping work of the circular panel assembly. The sliding clamp 375 is mainly used to position and clamp the panel assembly to ensure the accuracy of the position of the panel assembly. The design of the three clamps can achieve the effect of fully positioning and clamping the circular panel assembly according to the three-point circle theorem. The end of the limiting turntable 371 is elastically connected to the inside of the stamping base 1 through a torsion spring, the surface of the swing block 372 is connected to the surface of the swing connecting plate 376, the surface of the sliding clamp 375 is slidably connected to the inner wall of the stamping base 1, the surface of the swing connecting plate 376 is slidably connected to the inner wall of the stamping base 1, and the surface of the swing connecting plate 376 is elastically connected to the surface of the mounting seat 2 through a spring, the end of the extrusion rod 377 is fixedly connected to the surface of the roller rod 32, and the end of the extrusion rod 377 is set to an arc surface. The design of the arc surface allows the extrusion rod 377 to be in contact with the roller rod 32 for a long time during rotation. The swing connecting plate 376 is touched and squeezed, so that the limit turntable 371 ensures a long-term clamping angle, thereby achieving the purpose of continuous clamping. After the recessed punching head 53 completes a period of stamping, the squeezing rod 377 loses contact and squeezing of the swing connecting plate 376, and the sliding clamp 375 is reset under the influence of elastic force, and the panel assembly loses the clamping effect. Because the center area of ​​the panel assembly after a period of stamping is recessed inside the stamping groove 4, there is no need for the clamp to clamp it again. The panel can be positioned by utilizing the limitation of the groove, thereby satisfying the subsequent secondary stamping.

[0036] It is worth mentioning that the automatic lifting device 6 includes an elastic contact 61, a passive pressure plate 62 and a connecting lifting rod 63. The elastic contact 61 contacts the passive pressure plate 62 when rotating and pushes it upward. The connecting lifting rod 63 moves upward and lifts the panel assembly after the stamping work is completed, thereby achieving the purpose of automatically ejecting the panel after the stamping is completed, which is convenient for the subsequent robot or unloading equipment to unload the panel. The ejection setting of the unstamped area of ​​the panel is adopted to assist in unloading and avoid the problem of indentation in the stamping area caused by the impact of the stamping force and the ejection part. The surface of the elastic contact 61 is connected to the surface of the driving gear 33, the surface of the passive pressure plate 62 is elastically connected to the surface of the mounting seat 2 through a spring, and the surface of the connecting lifting rod 63 is slidably connected to the inside of the mounting seat 2 and the stamping base 1 respectively. The elastic contact 61 includes a fixed end rod 611 and an elastic end rod 612. The surface of the fixed end rod 611 is fixedly connected to the surface of the driving gear 33, and the end of the elastic end rod 612 is elastically connected to the end of the fixed end rod 611 through a torsion spring. When the elastic end rod 612 first contacts the passive pressure plate 62, it can drive the pressure plate upward through elastic force. When the pressure plate is upward for a certain distance and is restricted by the mounting seat 2 and cannot continue to move upward, the end rod that continues to contact the pressure plate will break through the elastic force and automatically give way, and will always keep driving the pressure plate upward during the period of giving way, until the end of the elastic end rod 612 completely loses contact with the pressure plate after giving way, and the pressure plate will reset downward. The main purpose of this design is to achieve the effect of connecting the lifting rod 63 to drive the stamped panel assembly to move upward to a specified height, and keep the panel at the specified height for a certain period of time, so as to facilitate the purpose of assisting the panel in unloading by a robot or other unloading equipment during the height maintaining time.

[0037] When a stamping mechanism based on a card-type furnace assembly of the present invention is in use, a manipulator or other transmission loading equipment places the panel in the card-type furnace assembly under the recessed stamping head 53, and by controlling the movement of the active motor 31, the output shaft of the motor drives the driving gear 33 fixed thereon through the roller rod 32 to intermittently engage the surface of the connecting gear 34, and the connecting gear 34 drives the stamping main rod 51 on the limit stamping frame 36 to stamp downward through the linked crankshaft 35. When a half section of teeth meshing with the connecting gear 34 rotates, the roller rod 32 rotates and squeezes the swing connecting plate 376 through the extrusion rod 377 fixed thereon, and the swing connecting plate 376 is forced to move laterally and drives the limit turntable 371 on the swing block 372 to rotate through the bottom end. When the limit turntable 371 rotates, the limit The slide groove 373 drives the sliding clamp block 375 on the limiting rod 374 to move linearly, and the three sliding clamp blocks 375 move synchronously toward the axis of the limiting turntable 371, contact the panel assembly during the movement and align and clamp it, so as to realize the clamping work before the panel assembly is stamped, and achieve the effect of automatic clamping and ensuring the stamping accuracy; during a period of stamping, the stamping main rod 51 performs a stamping on the panel assembly through the recessed stamping head 53 and the punching head 55, so that the central area of ​​the panel assembly is recessed downward, and after a period of stamping, the extrusion rod 377 loses contact with the swing connecting plate 376, and the swing connecting plate 376, the limiting turntable 371 and the sliding clamp block 375 are all reset by elastic force, and the panel loses the clamping effect of the clamp block, and is subsequently positioned by the restriction of the stamping groove 4;

[0038] After a stamping, a section of teeth on the driving gear 33 loses contact with the connecting gear 34. Before the two sections of teeth come into contact, the connecting gear 34 is in a short stop state. The previous ring seat 562 contacts the top of the stamping base 1 at the end of a stamping, and is controlled by the resistance of the bottom and the downward movement force, so that the ring seat 562 and the strong magnetic plate 561 thereon move upward inside the clamping base 52. When the connecting gear 34 is in a paused state, the upward strong magnetic plate 561 attracts the metal block 54 through magnetic attraction, and the block is separated from the inside of the socket 58 and the strong magnetic plate 561. 61 is magnetically connected, and the stamping main rod 51 loses the effect of the metal block 54 plug-in and no longer drives the recessed stamping head 53 to move. At this time, the recessed stamping head 53 temporarily remains in the stamping groove 4; when the second-stage teeth contact the connecting gear 34, the connecting gear 34 continues to rotate 180 degrees. During the rotation to 90 degrees, the gear drives the stamping main rod 51 on the stamping frame downward through the crankshaft to perform two-stage stamping. At this time, the stamping main rod 51 only drives the punching head 55 to perform two-stage stamping, so as to achieve the purpose of punching the recessed center area of ​​the panel. After the second-stage stamping is completed, the gear moves from During the rotation from 90 degrees to 180 degrees, the reset work after the second stage of stamping is realized, and the punching head 55 is retracted into the interior of the recessed stamping head 53 again. After the second stage of teeth contacts the connecting gear 34, one stage of teeth will contact the connecting gear 34 again and drive it to rotate. After half of one stage of teeth contacts the connecting gear 34, it returns to the initial state. During the recovery period, the connecting gear 34 continues to rotate 90 degrees, and the gear drives the stamping main rod 51 on the stamping frame upward through the crankshaft to perform the reset work after a stage of stamping. The stamping main rod 51 synchronously drives the recessed stamping head 5 on the clamping base 52 through the spring force. 3 is moved upward synchronously, during which the bottom of the ring seat 562 gradually loses contact with the mounting seat 2 and is reset by the elastic force of the rubber column 563, and the ring seat 562 drives the strong magnetic plate 561 to move downward in the clamping base 52, and the metal clamping block 54 gradually loses the magnetic adsorption force of the strong magnetic plate 561, and after completely losing the adsorption force, it is inserted into the insertion hole 58 again by the adsorption force of the magnetic sleeve 57 to be fixed, so as to achieve the effect of fixing the stamping main rod 51 and the clamping base 52 again, so that the stamping structure as a whole is restored to the initial state, thereby facilitating the subsequent secondary stamping work of the panel;

[0039] At the same time, when a section of teeth meshes with the connecting gear 34 again, the elastic contact 61 that rotates along the axis of the driving gear 33 contacts the passive pressure plate 62 during the rotation and pushes it upward, and the passive pressure plate 62 drives the connecting lifting rod 63 that is limited to only be able to move up and down in a straight line upward, and the connecting lifting rod 63 moves upward to achieve the effect of lifting the panel assembly after the stamping work is completed, and then achieves the purpose of automatically ejecting the panel after the stamping is completed, which is convenient for the subsequent robot or unloading equipment to unload the panel. Before the stamping main rod 51 is completely reset upward, the elastic contact 61 loses contact with the pressure plate, and the pressure plate and the lifting rod move and reset through elastic force.
