Description

Technical Field

[0001] This utility model relates to the technical field of stamping and punching devices, specifically a stamping and punching device for deburring hardware parts. Background Technology

[0002] In the manufacturing process of hardware parts, stamping and punching is a widely used processing technique. It involves quickly punching holes of the desired shape into sheet metal using stamping dies to meet the assembly and functional requirements of the parts. However, after the punching operation, existing hardware parts stamping and punching equipment inevitably produces burrs on the edges of the holes due to the plastic deformation of the metal material and the stress during the punching process. These burrs not only affect the dimensional accuracy and surface quality of the hardware parts, making precise fitting difficult during subsequent assembly and reducing the overall performance of the product, but they may also scratch operators or other mating parts during use, posing certain safety hazards.

[0003] Currently, burrs generated after stamping and punching are usually removed by manual grinding or secondary machining. Manual grinding relies on the experience and skill of the operator, which is inefficient and labor-intensive, making it difficult to meet the needs of mass production. Secondary machining requires additional processing equipment and processes, which significantly increases production costs. At the same time, improper operation during processing may cause new damage to the surface of the parts, thus affecting product quality.

[0004] To address this issue, the present invention provides a deburring punching and piercing device for hardware parts, thereby solving the aforementioned problems. Utility Model Content

A U-shaped frame 4 is provided inside the support frame 2, with both sides of the U-shaped frame 4 slidably connected to the corresponding mounting grooves 3. A punching mechanism is mounted on the support frame 2, and a deburring mechanism is mounted at the bottom of the U-shaped frame 4. The deburring mechanism includes a turntable 11 and a motor 12. The slide groove 13, slider 14 and bidirectional lead screw 15 are provided. A turntable 11 is rotatably installed at the middle position of the inner wall of the bottom end of the loop frame 4. A motor 12 is fixedly installed at the middle position of the bottom end of the loop frame 4. A drive shaft is fixedly installed at the output end of the motor 12. The drive shaft is fixedly connected to the turntable 11. A slide groove 13 is opened horizontally at the top of the turntable 11. A bidirectional lead screw 15 is rotatably installed inside the slide groove 13. Slider 14 is symmetrically slidably installed inside the slide groove 13. Each group of sliders 14 is threadedly connected to the bidirectional lead screw 15.

[0024] The deburring mechanism also includes a mounting hole 16, a rotating head 17, a hexagonal groove 18, an arc plate 19, an incomplete conical block 20, and abrasive bristles 21. The mounting hole 16 is provided on the outer right side of the turntable 11. The right side of the bidirectional lead screw 15 extends into the mounting hole 16 and is fixedly mounted with the rotating head 17. The right side of the rotating head 17 is provided with a hexagonal groove 18. The tops of the two sets of sliders 14 are fixedly mounted with arc plates 19. The tops of the two sets of arc plates 19 are fixedly mounted with incomplete conical blocks 20. Abrasive bristles 21 are fixedly mounted on the outer walls of the two sets of arc plates 19 and the two sets of incomplete conical blocks 20.

[0025] The punching mechanism includes a connecting plate 5, a hydraulic cylinder 6, a first telescopic rod 7, a punching head 8, a guide rod 9, and a clearance hole 10. The connecting plate 5 is fixedly installed at the middle position of the top of the U-shaped frame 4. The hydraulic cylinder 6 is fixedly installed at the middle position of the top of the support frame 2. The first telescopic rod 7 is fixedly installed at the output end of the hydraulic cylinder 6. The other end of the first telescopic rod 7 is fixedly connected to the connecting plate 5. The punching head 8 is fixedly installed at the bottom of the connecting plate 5. A clearance hole 10 is provided at the top of the worktable 1, directly below the punching head 8. Guide rods 9 are vertically fixedly installed on both sides of the top of the U-shaped frame 4. Both sets of guide rods 9 are slidably connected to the support frame 2. Limit blocks 35 are fixedly installed at the bottom of the inner walls on both sides of the U-shaped frame 4.

[0026] A PLC control panel 33 is fixedly installed on the outer right side of the support frame 2, and rubber pads 34 are fixedly installed at the four corners of the bottom of the workbench 1.

[0027] To facilitate control, this device is equipped with a PLC control panel 33 for centralized control of the hydraulic cylinder 6, motor 12, air cylinder 23, and dust extraction fan 29. The control program is set via the PLC control panel 33. When using this device, the operator first places the workpiece to be processed on the worktable 1, then starts the hydraulic cylinder 6, which drives the punch head 8 fixedly mounted on the connecting plate 5 via the first telescopic rod 7 to punch and pierce the workpiece. Simultaneously, the air cylinder 23 is started, which moves the receiving box 26 to a position directly below the clearance hole 10 via the second telescopic rod 24, allowing for the collection of waste and residue generated during punching and piercing. After punching and piercing is completed, the air cylinder 23 is restarted to move the receiving box 26 away from the position directly below the clearance hole 10. Finally, after punching and piercing is completed, the operator can restart the hydraulic cylinder 6, causing the loop frame 4 to move upwards. As the circular frame 4 moves upward, the deburring mechanism also moves upward. Simultaneously, the operator can start the motor 12, which drives the arc plate 19 to rotate via the turntable 11. This, in turn, drives the grinding brush 21 to deburr the opening of the workpiece. In the deburring mechanism, the arc plate 19 and the incomplete conical block 20 enable the grinding brush 21 to deburr the inside and edge of the opening, resulting in a higher burr removal effect and further improving the surface quality of the parts. In the deburring mechanism, the operator can also rotate the rotating head 17 with a tool, allowing the distance between the two sets of arc plates 19 to be adjusted via the bidirectional lead screw 15. This allows for the processing of deburring for different hole diameters, making the device more practical. Furthermore, this device integrates the punching mechanism and the deburring mechanism into the same unit, achieving integrated punching and deburring processing, thereby reducing processing steps and equipment space occupation, and improving production efficiency.

[0031] When the device deburrs the punched area, the operator can also simultaneously start the dust extraction fan 29, so that the dust and debris generated during the deburring process can be collected in time through the dust extraction hood 28, the first connecting pipe 30 and the second connecting pipe 32 and collected inside the dust collection box 31, keeping the working environment clean, reducing environmental pollution, and thus further improving the practicality of the device.
