Description

Technical Field

[0001] This utility model relates to the field of lock cylinder manufacturing technology, specifically a stamping device for deburring lock cylinders. Background Technology

[0002] In the lock cylinder manufacturing process, removing the burrs generated after processing the pin tumbler and key slots is a key process to ensure the precise fit of the lock cylinder. Traditional deburring equipment often uses independent horizontal or vertical stamping mechanisms to process the pin tumbler and key slots separately. However, due to the special structure of the lock cylinder, the burrs at the intersection of the pin tumbler and key slots need to be processed together.

[0003] During synchronous stamping, existing equipment often experiences interference between the burr punch and the lock cylinder due to conflicting movement trajectories of the stamped parts. This can range from affecting the deburring effect to damaging the punch or lock cylinder itself, increasing equipment maintenance costs and production risks. Furthermore, existing devices generally lack reliable interlocking mechanisms, making it impossible to stop the machine in time in case of misoperation or program malfunction, further exacerbating the equipment failure rate. Therefore, there is an urgent need for a lock cylinder deburring device that can effectively avoid stamping interference and improve safety. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides a stamping device for deburring lock cylinders. It offers the following advantages: Through the coordinated design of the vertical limiting plate and the horizontal limiting rod assembly, when the pin tumbler punch moves laterally, the limiting hole and the horizontal rod lock the downward movement path of the vertical stamping part. Conversely, when the key slot punch moves downward, the rightward movement path of the horizontal stamping part is restricted. This interlocking mechanism ensures that the pin tumbler and key slot punches cannot move simultaneously, completely eliminating the risk of motion interference at the intersection of the two at the lock cylinder, significantly reducing the probability of equipment damage. A push switch and a linkage push component are integrated into the horizontal limiting rod assembly. When a stamping part fails to reset or experiences motion conflict, the push switch is triggered via mechanical linkage, which in turn triggers the emergency stop cylinder, preventing equipment overload or workpiece damage due to misoperation or program errors.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 This utility model provides a technical solution for a stamping device for deburring lock cylinders: A stamping device for deburring lock cylinders includes a base plate 1, a vertical limiting plate 6, a limiting hole 7, and a horizontal limiting rod assembly 9. A lock cylinder limiting mold 2 is fixed on the top right side of the base plate 1. The lock cylinder limiting mold 2 is used to limit the lock cylinder 3. A horizontal stamping part 4 is provided on the left side of the lock cylinder limiting mold 2. The left side of the horizontal stamping part 4 is fixedly connected to the piston rod of the first cylinder 5. A vertical stamping part 8 is provided on the top of the lock cylinder limiting mold 2. The top of the vertical stamping part 8 is fixedly connected to the piston rod of the second cylinder 10.

[0028] The vertical limiting plate 6 is fixed to the top of the horizontal stamping part 4, the horizontal limiting rod assembly 9 is fixed to the left side of the vertical stamping part 8, and the top of the vertical limiting plate 6 is provided with a limiting hole 7 that is horizontally aligned with the horizontal limiting rod assembly 9.

[0029] The first cylinder 5 is arranged horizontally, and the second cylinder 10 is arranged vertically. The first cylinder 5 is fixed to the top left of the bottom plate 1, and the second cylinder 10 is fixed to the top of the top plate 11. Support plates 12 are fixed on both the left and right sides of the bottom end of the top plate 11, and the bottom end of the support plates 12 is fixedly connected to the bottom plate 1.

[0030] A ball groove punch 41 is fixed on the right side of the horizontal stamping part 4, and a key groove punch 81 is fixed at the bottom of the vertical stamping part 8. The ball groove punch 41 fits against the inner wall of the ball groove punch through hole 23.

[0031] Please see Figure 4-5 The horizontal limiting rod assembly 9 includes an outer frame 91, a horizontal bar 92, an insert rod 93, a slider 94, a slide rail 95, a push switch 96, and a push assembly 97. The right end of the horizontal bar 92 extends into the outer frame 91. The right end of the horizontal bar 92 is slidably connected to the insert rod 93. The right end of the insert rod 93 is fixedly connected to the slider 94. The slider 94 slides vertically along the slide rail 95, and the slide rail 95 is fixed to the bottom of the inner right side of the outer frame 91. The push switch 96 is installed on the top of the inner right side of the outer frame 91. The top right side of the horizontal bar 92 is connected to the push assembly 97. The push assembly 97 is used to press the push switch 96. The outer frame 91 is fixed to the left side of the vertical stamping part 8. The horizontal bar 92 is horizontally aligned with the position of the limiting hole 7.

[0032] The insertion rod 93 is arranged horizontally, while the slider 94 and the slide rail 95 are arranged vertically to restrict the movement of the crossbar 92, so that the crossbar 92 can move horizontally and vertically while maintaining its horizontal position.

[0033] The pressing assembly 97 includes a straight rod 971, a support plate 972, a limiting frame 973, a pressing plate 974, a spring 975, and a connecting rod 976. The support plate 972 is fixed to the left side of the outer wall of the straight rod 971. The right end of the straight rod 971 passes through the limiting frame 973 and is fixedly connected to the pressing plate 974. The straight rod 971 is arranged horizontally, and the inner wall of the limiting frame 973 is in contact with the straight rod 971. The left end of the limiting frame 973 is elastically connected to the support plate 972 through the spring 975, and the spring 975 is fitted on the outside of the straight rod 971. The left end of the straight rod 971 is rotatably connected to one end of the connecting rod 976 through a pivot, and the other end of the connecting rod 976 is rotatably connected to the crossbar 92 through a pivot.

[0034] The connecting rod 976 is inclined and tilts upward from left to right. Since the straight rod 971 is restricted in its movement trajectory by the limiting frame 973, when the horizontal bar 92 moves upward, it pushes the straight rod 971 to the right through the connecting rod 976. When the horizontal bar 92 moves to the right, it drives the straight rod 971 to move to the right through the connecting rod 976. The rightward movement of the straight rod 971 presses the push switch 96 through the press plate 974.

[0035] The top of the vertical limiting plate 6 is horizontally penetrated by the guide rod 13, and the vertical limiting plate 6 is slidably connected to the guide rod 13. The left and right ends of the guide rod 13 are fixedly connected to the top plate 11. The guide rod 13 restricts the movement trajectory of the vertical limiting plate 6, thereby increasing the stability of the movement of the vertical limiting plate 6.

[0036] Please see Figure 6-7 The lock cylinder limiting mold 2 includes a mold body 21, a lock cylinder limiting groove 22, a pin tumbler punch through hole 23 and a groove 24. The lock cylinder limiting groove 22 is vertically opened in the middle of the mold body 21, the pin tumbler punch through hole 23 is horizontally opened inside the mold body 21, and the groove 24 is opened at the top edge of the lock cylinder limiting groove 22.

[0037] The lock cylinder 3 has a horizontally oriented pin groove 31 inside, a vertically oriented key groove 32 inside, and a limiting protrusion 33 that matches the groove 24 on the top of the outer wall of the lock cylinder 3.

[0038] The mold body 21 restricts the placement angle of the lock cylinder 3 through the groove 24, which facilitates the placement of the lock cylinder 3 into the lock cylinder limiting groove 22. The pin tumbler groove 31, the pin tumbler groove punch through hole 23 and the pin tumbler groove punch 41 are horizontally aligned, so that the pin tumbler groove punch 41 moves horizontally through the pin tumbler groove punch through hole 23 to punch and deburr the pin tumbler groove punch 41. The key groove punch 81 is vertically aligned with the key groove 32 of the lock cylinder 3, and the key groove punch 81 moves down to punch and deburr the key groove 32.

[0039] The first cylinder 5 and the second cylinder 10 are SMC CJ2 series cylinders. The push switch (96) is used to send the cylinder stop command to the controller.

[0040] Emergency stop of cylinders is a mature existing technology. For example, the cylinder is equipped with a two-position five-way solenoid valve to support rapid cut-off of the air source. The PLC receives the trigger signal of the push switch (96) and outputs the command to close the solenoid valve. A fast exhaust valve is set in the air circuit of the cylinder. During emergency stop, the exhaust is released instantly, causing the cylinder to lose power and achieve the effect of emergency stop of the cylinder, avoiding equipment damage caused by interference between the burr punch and the lock core.

[0041] When in use, first place the lock cylinder 3 into the lock cylinder limiting groove 22 of the lock cylinder limiting mold 2, and then use the limiting protrusion 33 of the lock cylinder 3 to embed into the groove 24 to limit the placement of the lock cylinder 3;

[0042] When deburring the lock cylinder 3, firstly, control the first cylinder 5 to push the horizontal stamping part 4 and the pin slot punch 41 to the right. The pin slot punch 41 moves to the right and passes through the pin slot punch through hole 23 to deburr the pin slot punch 41. Then, control the second cylinder 5 to drive the horizontal stamping part 4 and the pin slot punch 41 to the left to reset. Control the second cylinder 10 to drive the vertical stamping part 8 and the key slot punch 81 to move down. The key slot punch 81 moves down to deburr the key slot 32.

[0043] Because the pin tumbler groove 31 and key groove 32 of the lock cylinder 3 intersect, the pin tumbler groove punch 41 and key groove punch 81 cannot simultaneously punch and deburr the pin tumbler groove 31 and key groove 32 of the lock cylinder 3.

[0044] By setting a vertical limiting plate 6 and a horizontal limiting rod assembly 9 to restrict the simultaneous movement of the pin tumbler punch 41 and the key slot punch 81, when the horizontal stamping part 4 and the pin tumbler punch 41 move to the right, the vertical limiting plate 6 moves to the right synchronously, so that the limiting hole 7 of the vertical limiting plate 6 is inserted into the horizontal bar 92 of the horizontal limiting rod assembly 9, thus restricting the downward movement of the horizontal bar 92, which in turn restricts the downward movement of the key slot punch 81. When the vertical stamping part 8 and the key slot punch 81 move downward, the horizontal limiting rod assembly 9 moves downward synchronously, thus restricting the rightward movement of the vertical limiting plate 6, which in turn restricts the rightward movement of the pin tumbler punch 41. This avoids the pin tumbler punch 41 and the key slot punch 81 simultaneously punching burrs on the pin tumbler 31 and the key slot 32 of the lock cylinder 3, causing the pin tumbler punch 41 and the key slot punch 81 to block each other, resulting in damage to parts or equipment.

[0045] Furthermore, a push switch 96 is provided for emergency stopping of the first cylinder 5 and the second cylinder 10. After the first cylinder 5 drives the transverse stamping part 4 and the ball groove punch 41 to move to the right, if the transverse stamping part 4 and the ball groove punch 41 do not move to the left to reset, since the limiting hole 7 of the vertical limiting plate 6 is inserted with the horizontal bar 92, the second cylinder 10 is controlled to move down, which drives the vertical stamping part 8 and the transverse limiting rod assembly 9 to move down. Since the downward movement of the horizontal bar 92 is restricted, the horizontal bar 92 drives the slider 94 to move up along the slide rail 95 through the insert rod 93, and the horizontal bar 92 drives the straight rod 971 to move to the right through the connecting rod 976. The push switch 96 is pressed by the push plate 974 on the right side of the straight rod 971, triggering the control to stop the operation of the first cylinder 5 and the second cylinder 10.

[0046] After the second cylinder 10 drives the vertical stamping part 8 and the key groove punch 81 to move down, if the vertical stamping part 8 and the key groove punch 81 do not move to the left to reset, the horizontal bar 92 moves down at this time, and the horizontal bar 92 is at a different height from the limiting hole 7. At this time, the first cylinder 5 is controlled to drive the horizontal stamping part 4, the ball groove punch 41 and the vertical limiting plate 6 to move to the right. The vertical limiting plate 6 pushes the horizontal bar 92 to move to the right along the insertion rod 93, and the horizontal bar 92 drives the straight rod 971 to move to the right through the connecting rod 976. The straight rod 971 moves to the right through the pressing plate 974 to press the pressing switch 96, triggering the control to stop the operation of the first cylinder 5 and the second cylinder 10, stopping the operation of the first cylinder 5 and the second cylinder 10 in time, effectively avoiding damage to the burr punch or equipment caused by incorrect operation.
