Description

Technical Field

[0001] This application relates to the technical field of stamping machines, and in particular to a snap-lock stamping machine. Background Technology

[0002] The trip clip is a component inside a molded case circuit breaker. The trip clip is usually directly stamped and fixed by a stamping machine, which is a machine that squeezes and fixes two objects together.

[0003] In related technologies, the jump buckle includes a buckle plate and a rotating shaft, which need to be fixed by stamping. The stamping machine includes a support frame, on which a stamping head, a first cylinder, a second cylinder, a slide rail, and a fixed seat are provided. The fixed seat has an installation groove for installing the jump buckle. The slide rail is located below the fixed seat and is slidably connected to the slide rail. The second cylinder drives the fixed seat to move along the length of the slide rail, and the first cylinder drives the stamping head to move. The stamping head is located directly above the slide rail. When the fixed seat moves below the stamping head, the stamping head stamps the jump buckle towards the fixed seat.

[0004] Because the jumper clip is embedded in the mounting slot, workers need to remove the jumper clip from the mounting slot and then insert the prepared jumper clip into the mounting slot before the motor can be started, which reduces the efficiency of the jumper clip in stamping. Summary of the Invention

[0005] To address the issue of needing to manually remove the snap fastener, this application provides a snap fastener punching machine.

[0006] This application provides a snap-fit ​​punching machine, which adopts the following technical solution:

[0007] A snap-fit ​​punching machine includes a support frame, which includes a punching head, a mounting base, a fixing block, and a driving component. A groove is formed on the end face of the fixing block, and the mounting base is slidably connected within the groove. The driving component drives the mounting base to slide on the groove. An mounting slot for mounting snap-fits is formed on the end face of the mounting base. The punching head is located on one side of the fixing block, and the mounting slot penetrates the mounting base towards its side. A limiting member and a fixing member are provided on the end face of the fixing block. The limiting member drives the snap-fits to disengage from the mounting slot, and the fixing member moves the limiting member. When an unpunched snap-fit ​​is moving, the limiting member is not on the snap-fit's movement path; when a punched snap-fit ​​is located in the mounting slot and the snap-fit ​​is moving, the limiting member is on the snap-fit's movement path.

[0008] By adopting the above technical solution, when the unpressed jumper moves towards the pressing head, the fixing component drives the limiting component to move, so that the limiting component is not located on the movement path of the jumper. This makes it difficult for the limiting component to drive the jumper away from the mounting slot, allowing the jumper to move towards the pressing head, and thus allowing the pressing head to press the jumper. When the pressed jumper moves away from the pressing head and is located in the mounting slot, the fixing component drives the limiting component to move onto the movement path of the jumper. This allows the limiting component to allow the jumper to detach from the mounting slot, enabling the pressed jumper to be automatically unloaded. This eliminates the need for workers to remove the jumper from the mounting slot, meaning that unpressed jumpers can be directly installed in the mounting slot, reducing the number of steps for workers, simplifying the operation, and improving the pressing efficiency of the jumper.

[0009] Optionally, the end face of the fixing block is provided with a baffle and a fixing rod. The limiting member and the fixing member are both disposed on the fixing rod. The fixing member includes a fixing ring, a fixing plate and a limiting plate. The fixing ring is sleeved on the fixing rod. The fixing plate and the limiting plate are both disposed on the outer circumferential surface of the fixing ring. The limiting member is disposed on the end face of the fixing plate. When the fixing plate abuts against the baffle, the limiting plate is located on the moving path of the mounting base and the limiting member is located on the moving path of the jump buckle. When the limiting plate abuts against the baffle, the fixing plate is located on the moving path of the mounting base and the limiting member is not located on the moving path of the jump buckle.

[0010] By adopting the above technical solution, when the mounting seat moves towards the stamping head, the fixing plate is located on the moving path of the mounting seat, allowing the mounting seat to abut against the end face of the fixing plate. The mounting seat drives the fixing plate to rotate around the fixing rod until the fixing plate abuts against the baffle. At this time, the limiting plate is located on the moving path of the mounting seat, and the limiting member is located on the moving path of the jump buckle. When the mounting seat moves away from the stamping head, the limiting plate is located on the moving path of the mounting seat, allowing the mounting seat to abut against the end face of the limiting plate. The mounting seat drives the limiting plate to rotate around the fixing rod until the limiting plate abuts against the baffle. At this time, the fixing plate is located on the moving path of the mounting seat, and the limiting member is not on the moving path of the jump buckle. Through the cooperation between the fixing plate and the limiting plate, the limiting member can be located on the moving path of the jump buckle and move away from the moving path of the mounting seat as the mounting seat moves. This allows the mounting seat to drive the limiting member to rotate while moving, so that the limiting member does not need to be moved by an additional driving component.

[0011] Optionally, a placement groove is provided on the end face of the fixing plate away from the limiting member, and a first magnet is provided in the placement groove. A receiving groove is provided on the end face of the baffle, and a second magnet that attracts the first magnet is provided in the receiving groove. When the fixing plate abuts against the baffle, the first magnet attracts the second magnet, and the mounting base can drive the limiting plate to rotate.

[0012] By adopting the above technical solution, the baffle and the fixed plate are fixed together by the mutual attraction of the first magnet and the second magnet. When the fixed plate moves towards the baffle, the fixed plate is not easily blocked by the baffle and will not rebound, so that the limiting plate can be located on the moving path of the mounting base, thereby allowing the fixing component to drive the limiting component to move. When the mounting base abuts against the limiting plate, the limiting plate can drive the fixed plate to rotate around the fixing rod, so that the fixed plate can be located on the moving path of the mounting base, and the limiting component is not located on the moving path of the jump buckle.

[0013] Optionally, the limiting component includes a guide plate, which is not on the moving path of the mounting base. The end face of the guide plate away from the limiting plate has an inclined surface, which is inclined in the direction away from the limiting plate and away from the fixing plate. The mounting groove passes through the mounting base in the direction of the fixing rod. When the guide plate abuts against the jump buckle, the mounting base does not abut against the limiting plate.

[0014] By adopting the above technical solution, the jumper abuts against the inclined surface, causing the jumper to move away from the mounting seat along the extension direction of the mounting groove, thereby allowing the guide plate to drive the jumper to disengage from the mounting seat; when the guide plate abuts against the jumper, the mounting seat does not abut against the limiting plate, making it difficult for the fixing plate to rotate, thereby allowing the guide plate to drive the jumper to move.

[0015] Optionally, a through hole is provided on the end face of the fixing block for the jumper to fall down.

[0016] By adopting the above technical solution, the jump clips can continue to fall after falling from the mounting base, making it less likely for the jump clips to accumulate on the fixed block. This reduces the impact of excessive jump clip accumulation on the fixed block on the normal movement of the mounting base, allowing the mounting base to continue sliding along the length of the slide groove and facilitating the collection of the jump clips.

[0017] Optionally, the mounting base is provided with a shielding component, which shields the opening in the through direction of the mounting groove. When the jumper is inserted into the mounting groove, the jumper abuts against the shielding component and the groove wall of the mounting groove, and the limiting member can drive the jumper to disengage from the mounting groove.

[0018] By adopting the above technical solution, the opening in the through direction of the mounting groove is blocked by the shielding component, making it difficult for the jumper to detach from the mounting groove during the movement of the mounting seat. This allows the jumper to be stamped, improving the accuracy of the jumper stamping.

[0019] Optionally, the blocking assembly includes a stop block and a movable component. The groove wall of the mounting groove is provided with a slot for the stop block to rotate. The slot is connected to a through hole. The end face of the stop block is provided with a stop hole for the jump buckle to pass through. The stop hole extends to the outer surface of the stop block. The movable component is used to drive the stop hole to communicate with the mounting groove. When the limiting component drives the jump buckle to disengage from the mounting groove, the slot is connected to the mounting groove.

[0020] By adopting the above technical solution, the jumper buckle is disengaged from the stop block in the stop hole, allowing the limiting component to move the jumper buckle, which facilitates the jumper buckle's disengagement from the mounting groove. The moving component drives the stop block to rotate, allowing the stop block to rotate within the groove, thus allowing the stop hole to rotate. This ensures that the extension direction of the mounting groove is blocked by the end face of the stop block, making it difficult for the jumper buckle to move from the through direction of the mounting groove, resulting in greater stability when the jumper buckle is located within the mounting groove.

[0021] Optionally, the wall of the stop hole is provided with a protrusion, which is used to prevent the jumper from easily passing through the stop hole.

[0022] By adopting the above technical solution, the protrusion restricts the jumper, making it difficult for the unpressed jumper to pass through the stop hole, allowing the jumper to be stably positioned in the mounting groove.

[0023] Optionally, the moving component includes a rack, and the end face of the fixed block is provided with a through hole that connects to the slide groove. The rack is disposed on the bottom wall of the slide groove and is located in the through hole. The outer circumferential surface of the stop block is provided with external teeth that mesh with the rack, and the stop block can rotate along the length direction of the rack.

[0024] By adopting the above technical solution, the intermeshing of the external teeth and the rack allows the stop block to rotate along the length of the rack, thereby allowing the stop hole to connect with the mounting groove when needed, so that the jumper can move out of the mounting groove.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The limiting component is moved by the fixing component, so that the limiting component is located on the moving path of the jump buckle. This allows the jump buckle to be driven by the limiting component to disengage from the mounting slot. After stamping, the jump buckle can be automatically unloaded as the mounting base moves, reducing the number of operation steps for the operator, thus simplifying the operation and improving the stamping efficiency of the jump buckle.

[0027] 2. Through the cooperation between the fixed plate and the limiting plate, the mounting base can abut against the fixed plate when sliding in the groove, so that the fixed plate can drive the limiting plate to rotate, thereby placing the limiting component on the moving path of the jump buckle, so that the limiting component does not need other driving components to move.

[0028] 3. By using the jumper to abut against the inclined surface, the jumper can disengage from the mounting groove along the extension direction of the mounting groove, so that the guide plate can drive the jumper to disengage from the mounting groove, thereby realizing the automatic unloading of the jumper.

[0055] Re-activate the first cylinder 41, causing the mounting base 2 to move away from the first cylinder 41. The guide plate 61 abuts against the jump buckle. At this time, the stop hole 811 is connected to the mounting groove 21. As the mounting base 2 continues to move, the jump buckle abuts against the guide plate 61, causing the jump buckle to disengage from the mounting groove 21 along the through direction until the mounting base 2 abuts against the limiting plate 73. As the mounting base 2 continues to move, the limiting plate 73 rotates around the fixed rod 5 until the third magnet 732 attracts the fourth magnet 324, that is, the limiting plate 73 abuts against the baffle 32. At this time, the fixed plate 72 is located on the moving path of the mounting base 2, and the guide plate 61 is not on the moving path of the mounting base 2 and the jump buckle.
