Description

Technical Field

[0001] This utility model relates to the field of fastener manufacturing technology, specifically to a rounding device for fastener manufacturing. Background Technology

[0002] Bolts are a type of mechanical part that uses the principle of threaded connection to fasten two or more connected parts together. They are widely used in many fields such as machinery manufacturing, construction, automobiles, and aerospace, and are the basic components for achieving component connection.

[0003] In the field of mechanical manufacturing, rounding the corners of fasteners is a key step in improving product quality and assembly performance. However, traditional rounding devices have significant problems in practical applications. First, they suffer from poor clamping and processing stability. Traditional clamping structures are prone to damaging the fastener surface, and uneven clamping force distribution causes workpiece wobbling or displacement during processing, which not only reduces processing accuracy but also poses a risk of tool collision. Second, they are not environmentally friendly. The metal shavings and dust generated during the rounding process lack effective collection and treatment, easily spreading into the working environment and endangering the health of operators. At the same time, shavings accumulation can interfere with equipment operation, accelerate component wear, shorten equipment lifespan, and increase environmental compliance costs for enterprises due to non-compliance with emission standards. Utility Model Content

[0026] Based on Embodiments 1 and 2, a preferred embodiment of the chamfering device for fastener production provided by this utility model is, for example... Figure 1-4 As shown: The vacuuming component 42 includes: a vacuum hood 421, fixedly installed on the inner side of the L-shaped connecting plate 416; a collection box 422, fixedly installed on the back of the support plate 411; a flexible hose 423 is connected to the top of the collection box 422, the other end of the flexible hose 423 movably passes through the outer side of the L-shaped connecting plate 416 and extends to the inner side of the L-shaped connecting plate 416, and is connected to the vacuum hood 421; the vacuum hood 421 is located on one side of the blade holder 419 and the blade 4111; a connecting pipe 428 is connected to the bottom of the collection box 422. A powerful suction pump 429 is connected to the bottom end, and an exhaust pipe 4211 is connected to the output end of the powerful suction pump 429. A movable opening is provided on one side of the outer side of the receiving box 422. Slide rods 424 are fixedly installed on both sides of the inner wall of the receiving box 422. A receiving drawer 425 is slidably connected to the outer wall of the slide rods 424. A filter hole is provided at the bottom of the receiving drawer 425. The receiving drawer 425 is movably connected to the receiving box 422 through the movable opening. An outer plate 426 is fixedly installed on the outer side of the receiving drawer 425, and a handle 427 is fixedly installed on the outer side of the outer plate 426.

[0027] Furthermore, in this embodiment, a powerful suction pump 429 is started simultaneously, and a negative pressure airflow is formed through the dust suction hood 421, hose 423 and connecting pipe 428. The debris generated by cutting is sucked into the receiving drawer 425 in the receiving box 422. The air is discharged through the filter hole and purified by the exhaust pipe 4211. After processing is completed, the receiving drawer 425 can be pulled out by the handle 427 to clean up the debris.

[0028] In use, when rounding the corners of bolt fasteners is required, the fasteners to be processed are placed in the storage slots on top of the storage circular plate 312.

The connecting plates 4115, through the connecting block 4116, drive the arc-shaped clamping plate 4117 to close, clamping the fastener. The rubber pad 4118 increases friction and prevents damage to the workpiece. The electric guide rail 412 drives the slide 413 along the guide rail. Sliding towards the short rod 414, the movable plate 415 and the L-shaped connecting plate 416 descend, bringing the blade 4111 close to the edge of the fastener. Motor 417 starts, driving the tool holder 419 and blade 4111 to rotate at high speed via the connecting shaft 418, rounding the edge of the fastener. The electric guide rail 412 controls the feed depth and speed of the blade 4111 according to preset parameters, ensuring the rounded radius meets process requirements. During the rounding process, the powerful suction pump 429 starts simultaneously, forming a suction system through the dust hood 421, hose 423, and connecting pipe 428. Negative pressure airflow draws the debris generated during cutting into the receiving drawer 425 inside the receiving box 422. The air is discharged through the filter holes and purified through the exhaust pipe 4211. After processing, the receiving drawer 425 can be pulled out by the handle 427 to clean up the debris. After processing a single fastener, the motor 3 4112 reverses, the arc-shaped clamping plate 4117 is released, the electric guide rail 412 drives the blade 4111 to rise and reset, the motor 1 313 starts again, and rotates the next fastener to be processed to the processing position. The steps are repeated to achieve continuous batch production.
