Description

Technical Field

[0001] This utility model relates to the technical field of stripping mechanisms, specifically a stripping mechanism for bending hardware parts. Background Technology

[0002] In the field of hardware parts processing, bending is a crucial step, and the stripping mechanism, as an important auxiliary device in the bending process, directly affects the processing efficiency and quality of hardware parts.

[0003] Most stripping mechanisms on the market today reset the pressure block to its initial position via mechanical structure or elastic element after completing the bending operation and stripping the metal parts. However, these reset mechanisms often lack reliable limiting and fixing devices, causing the pressure block to be unable to remain stably in the predetermined position after reset. During long-term operation or when subjected to external interference, the pressure block is prone to slight displacement or vibration, which in turn affects the accuracy and consistency of subsequent bending operations. Utility Model Content

[0004] The purpose of this utility model is to provide a stripping mechanism for bending hardware parts, in order to solve the problem mentioned in the background art that most stripping mechanisms on the market at present, after completing the bending operation and stripping the hardware parts, will reset the lower pressure block to the initial position through a mechanical structure or elastic element. However, these reset mechanisms often lack reliable limiting and fixing devices, which causes the lower pressure block to be unable to stably maintain the predetermined position after reset. When running for a long time or under external interference, the lower pressure block is prone to slight displacement or vibration, which in turn affects the accuracy and consistency of subsequent bending operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material stripping mechanism for bending hardware parts, comprising a base, a top frame fixedly installed on the outer side of the top of the base, a support plate fixedly installed at the center of the top of the base, a pressing block disposed at the center of the top of the support plate, a movable plate disposed at the center of the top of the support plate corresponding to the lower pressing block, a bottom block fixedly connected to the center of the bottom of the pressing block, side plates fixedly connected to the top of the base corresponding to the front and rear sides of the pressing block, and rotating rods fixedly connected to the bottom positions of the front and rear sides of the pressing block, the side of the rotating rod away from the pressing block being rotatably connected to the center position of the side plate, and the two side plates disposed at the front and rear. Two connecting rods are fixedly connected to the center of each opposite side. A fixing plate is fixedly connected to the side of the two connecting rods away from the side plate. A variable frequency motor is fixedly installed on the side of the fixing plate away from the two connecting rods. Threaded rods are fixedly connected to the output ends of the two variable frequency motors on opposite sides. The side of the threaded rod away from the variable frequency motor is rotatably connected to the side plate. A threaded sleeve plate is threadedly connected to the center position of the threaded rod. The two sides of the threaded sleeve plate are sleeved and slidably connected to the two connecting rods. Limiting rods are fixedly connected to the two ends of the opposite side of the two threaded sleeve plates. The side of the limiting rod away from the threaded sleeve plate passes through the side plate and the lower pressure block in sequence and is engaged with the lower pressure block.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This metal parts bending and stripping mechanism uses a linkage structure consisting of a variable frequency motor, a threaded rod, a threaded sleeve, and a limiting rod on opposite sides of the side plate. After the metal parts are bent and stripped, the lower pressure block is reset to its initial position via a rotating rod. At this time, the two variable frequency motors set at the front and rear start synchronously, driving the threaded rod to rotate and causing the threaded sleeve to slide along the connecting rod. This allows the limiting rods on both sides to accurately pass through the side plate and engage with the pre-set slots of the lower pressure block. This limiting structure achieves absolute positioning of the lower pressure block through a rigid mechanical connection, effectively eliminating minor offsets or vibrations after reset. It ensures that the relative position of the lower pressure block and the support plate is completely consistent during each bending operation, significantly improving the bending dimensional accuracy and batch consistency of the metal parts.

The side of the threaded rod 22 away from the variable frequency motor 21 is rotatably connected to the side plate 17. A threaded sleeve plate 23 is threadedly connected to the center position of the threaded rod 22. The two sides of the threaded sleeve plate 23 are sleeved and slidably connected to the two connecting rods 19. Limiting rods 24 are fixedly connected to the two ends of the opposite side of the two threaded sleeve plates 23 arranged at the front and rear. The side of the limiting rod 24 away from the threaded sleeve plate 23 passes through the side plate 17 and the lower pressure block 6 in sequence and is engaged with the lower pressure block 6.

[0015] A cylinder 3 is fixedly installed at the center of the top of the top frame 2. The output end of the cylinder 3 extends through to the bottom of the top frame 2 and is fixedly installed with an upper pressure block 4.

[0016] A movable groove 8 is provided on the top of the support plate 5 corresponding to the lower part of the movable plate 7. A movable block 9 is fixedly connected to one side of the bottom of the movable plate 7. The bottom of the movable block 9 extends through the interior of the movable groove 8 and is slidably connected to the movable groove 8.

[0017] A support rod 10 is fixedly connected inside the movable groove 8. The support rod 10 is sleeved and slidably connected to the movable block 9. A buffer spring 11 is sleeved on one side of the surface of the support rod 10. The two sides of the buffer spring 11 are fixedly connected to the movable groove 8 and the movable block 9, respectively.

[0018] An arc-shaped groove 12 is provided at the center of the top of the movable plate 7. A trapezoidal abutment plate 13 is fixedly connected to one side of the top of the movable plate 7 corresponding to the arc-shaped groove 12. The bottom of the base block 14 penetrates into the interior of the arc-shaped groove 12 and contacts the arc-shaped groove 12.

[0019] A cylinder 15 is fixedly installed on one side of the top of the base 1. A movable rod 16 is fixedly connected to the output end of one side of the cylinder 15. One side of the movable rod 16 is fixedly connected to one side of the movable plate 7.

[0020] A receiving tray 25 is placed on the other side of the top of the support plate 5.

[0021] Working principle: When unloading is required, the two variable frequency motors 21 set at the front and rear start synchronously, driving the threaded rod 22 to rotate, which drives the threaded sleeve plate 23 to slide along the connecting rod 19 to both sides, so that the limiting rod 24 disengages from the slot of the lower pressure block 6; the cylinder 2 15 pushes the movable plate 7 to move to the left along the moving groove 8 through the movable rod 16, the moving block 9 slides on the surface of the support rod 10 and compresses the buffer spring 11. As the movable plate 7 moves, the bottom block 14 slides in the arc groove 12, and the inclined surface of the trapezoidal abutment plate 13 gradually pushes the bottom block 14, so that the lower pressure block 6 rotates clockwise around the rotating rod 18. After the lower pressure block 6 tilts, the hardware parts on its surface slide down the inclined surface under the action of gravity and finally fall into the receiving tray 25.

[0022] In summary, this material removal mechanism for bending hardware parts utilizes a linkage structure consisting of a variable frequency motor 21, a threaded rod 22, a threaded sleeve 23, and a limiting rod 24 on the opposite side of the side plate 17. After the hardware part is bent and removed, the lower pressure block 6 is reset to its initial position via the rotating rod 18. At this time, the two variable frequency motors 21 set at the front and rear start synchronously, driving the threaded rod 22 to rotate and causing the threaded sleeve 23 to slide along the connecting rod 19. This allows the limiting rods 24 on both sides to accurately penetrate the side plate 17 and engage with the pre-set slots of the lower pressure block 6. This limiting structure achieves absolute positioning of the lower pressure block 6 through a rigid mechanical connection, effectively eliminating minor offsets or vibrations after reset. This ensures that the relative positions of the lower pressure block 6 and the support plate 5 are completely consistent during each bending operation, significantly improving the bending dimensional accuracy and batch consistency of the hardware parts.
