Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0022] Example 1
[0023] like Figures 1 to 5 As shown, a tearing device for thicker hardware parts includes a frame 1, a lower die 8 fixed at the bottom of the frame 1, an upper die 7 arranged above the lower die 8, hydraulic cylinders 4 symmetrically installed between the upper die 7 and the frame 1, and a slotting assembly 2 arranged between the upper die 7 and the lower die 8.
[0024] The slotting assembly 2 is fixedly connected to three slotting blades 21 at the bottom of the upper mold 7. A top block 22 is fixedly connected to the side of the upper surface of the lower mold 8 near the slotting blades 21, and the top block 22 is aligned with the side of the top block 22.
[0025] During the processing of hardware parts, the material strip 6 is conveyed by the guide roller 5. When the material strip 6 passes between the lower die 8 and the upper die 7, the hydraulic cylinder 4 pushes the upper die 7 to move downward. Then, the pressing knife 21 and the top block 22 work together to press the hardware parts, forming multiple sets of pressing grooves. This reduces the occurrence of cracking of the material strip 6 in subsequent stamping processes. Moreover, the multiple sets of pressing grooves can maintain the continuity of the material strip 6, which facilitates the continuous operation of subsequent processes and improves the processing efficiency of hardware parts.
[0026] Inside the frame 1, fixed frames 9 are symmetrically and fixedly connected. Guide rollers 5 are rotatably connected between the fixed frames 9. A material belt 6 is set above the guide rollers 5. Guide posts 23 are symmetrically and fixedly connected to the bottom surface of the upper mold 7. Fixed seats 25 are symmetrically and fixedly connected to the upper surface of the lower mold 8 near the guide posts 23. A T-shaped buffer sleeve 24 is slidably connected inside the fixed seat 25. The surface of the buffer sleeve 24 is provided with a guide groove that matches the guide posts 23. A first spring 26 is sleeved on the outside of the buffer sleeve 24. The two ends of the first spring 26 abut against the buffer sleeve 24 and the fixed seat 25, respectively.
[0027] When the upper die 7 moves downward, the guide columns 23 on both sides will be inserted into the buffer sleeve 24, and the movement of the guide columns 23 is guided by the buffer sleeve 24, which ensures the stability of the movement of the pressure groove cutter 21 and the upper die 7, and the pressure of the guide columns 23 can be buffered by the first spring 26, thereby improving the service life of the device.
[0028] Embodiment Two
[0029] In addition to including all the technical features in Embodiment One, this embodiment also includes:
[0030] The surface of the fixed frame 9 is provided with a guide assembly 3, which includes a compression wheel 31 symmetrically arranged above the material guide roller 5. A fixed column 35 is fixedly connected to the inside of the fixed frame 9 near the compression wheel 31. A sliding block 33 is slidably connected to the surface of the fixed column 35, and one end of the compression wheel 31 is rotatably connected to the sliding block 33. A second spring 32 is arranged above the sliding block 33 and is sleeved on the surface of the fixed column 35. A lever 34 is fixedly connected to one side of the sliding block 33, and an active slot is formed in the inside of the fixed frame 9 near the lever 34.
[0031] The material guide roller 5 is connected to a driving mechanism on one side, which can drive the material guide roller 5 to rotate and convey the material belt 6. During this period, the sliding block 33 will be driven by the pressure of the second spring 32 to move the compression wheel 31, which will compress the material belt 6 on both sides, improving the stability of the material belt 6 conveying. The position of the compression wheel 31 can be adjusted adaptively according to the thickness of the hardware, which is convenient for compressing and limiting the material belt 6 of different thicknesses, improving the flexibility of the device. By pulling the lever 34, the compression wheel 31 can be moved upward, which is convenient for placing the hardware between the compression wheel 31 and the material guide roller 5.
[0032] Working principle: During the processing of the hardware, the material belt 6 is conveyed by the material guide roller 5, and at the same time, the sliding block 33 will be driven by the pressure of the second spring 32 to move the compression wheel 31, which will compress the material belt 6 on both sides, improving the stability of the material belt 6 conveying. The position of the compression wheel 31 can be adjusted adaptively according to the thickness of the hardware, which is convenient for compressing and limiting the material belt 6 of different thicknesses. When the material belt 6 passes between the lower die 8 and the upper die 7, the hydraulic cylinder 4 will push the upper die 7 to move downward, and then the pressure groove cutter 21 cooperates with the top block 22 to perform a pressure marking operation on the hardware, forming multiple pressure marking grooves, which reduces the occurrence of material belt 6 cracking in the subsequent stamping process. Through multiple pressure marking grooves, the connectivity of the material belt 6 can be maintained, which is convenient for the continuous performance of the subsequent process. When the upper die 7 moves, the guide columns 23 on both sides will be inserted into the buffer sleeve 24, and the movement of the guide columns 23 is guided by the buffer sleeve 24, which ensures the stability of the movement of the pressure groove cutter 21 and the upper die 7.
