Description

Technical Field

[0001] This utility model relates to a precious metal jewelry accessory processing device, specifically a device for cutting hollow beads in a row. Background Technology

[0002] In precious metal jewelry, to reduce material consumption and increase volume, the use of hollow precious metal beads, or the processing of different patterns or reflective surfaces on the surface of hollow beads to enhance decorative effects, has become widely adopted. Currently, commonly used hollow precious metal beads have diameters between 3-8 mm and wall thicknesses between 0.05-0.25 mm. The processing of hollow precious metal beads involves forging tubular material into rows of hollow beads (see attached image). Figure 1 and 2 The process involves cutting the row of hollow beads into individual hollow beads.

[0003] The existing technology for cutting rows of hollow beads into individual hollow beads uses a single active cutting blade. Due to the low strength of precious metals (such as gold and silver) and the thinness of the hollow bead walls, the hollow beads deform after cutting, which greatly reduces the yield of hollow beads and results in low cutting efficiency. Utility Model Content

[0004] To address the shortcomings of existing hollow bead slitting equipment, which results in deformed hollow beads and low yield and efficiency, this utility model discloses a slitting device for connected hollow bead materials.

[0005] The technical solution adopted by this utility model to achieve the purpose of the invention is: a row of hollow bead cutting device, including: a frame part, a power head part, a bead guiding and positioning part, a cutting tool slide part and a sliding guide part.

[0006] The power head part includes: a power motor and a bead chuck, wherein the output shaft of the power motor is coaxially and fixedly connected to the bead chuck, and the power motor is fixedly mounted on the frame part; The bead guiding and positioning part includes: a guide tube, a positioning block, and a guide positioning bracket. The guide tube is coaxially mounted on the guide positioning bracket with the bead chuck of the power head part. The positioning block is threadedly connected to the guide positioning bracket via a screw. The guide positioning bracket is fixedly mounted on the slitting tool slide part. The slitting tool slide section includes: a pair of slitting blades, a pair of slitting blade shafts, a pair of slitting blade radial slide plates, an axial slide, a slitting blade radial control gear, a slitting blade radial control upper rack, a slitting blade radial control lower rack, and a gear control rod; The slitting blade is mounted on a slitting blade shaft, which is rotatably supported on a radial sliding plate. A pair of radial sliding plates are symmetrically mounted horizontally on an axial slide via dovetail guides. The radial control gear is rotatably supported on the axial slide. One end of the gear control rod is fixedly connected to the central shaft of the radial control gear. The upper and lower radial control racks are respectively fixed on a pair of radial sliding plates and mesh with the upper and lower radial control gears. The axial slide is fixedly connected to the guide positioning bracket of the bead guide positioning part and forms a sliding connection with the sliding guide part. The sliding guide part includes a guide rod and a guide rod bracket. The guide rod bracket is fixedly installed on the frame part, and the guide rod is fixed on the guide rod bracket. The guide rod and the axial slide in the sliding tool slide part form a sliding connection with a shaft hole fit.

[0007] The advantages of this invention are: simple structure, simultaneous cutting with passive double blades to reduce the cutting force on the hollow beads, greatly reducing deformation of the hollow beads, and improving production efficiency. It is particularly suitable for cutting small-diameter, thin-walled, multi-row hollow beads.

[0015] Referring to the attached drawings, a row of hollow bead cutting device includes: a frame part, a power head part, a bead guiding and positioning part, a cutting tool slide part, and a sliding guide part.

[0016] The power head part includes a power motor 2-1 and a bead chuck 2-2. The output shaft of the power motor 2-1 is coaxially and fixedly connected to the bead chuck 2-2. The power motor 2-1 is fixedly mounted on the frame part 1.

[0017] During operation, the bead chuck 2-2 clamps the tube 7-1 in the row of hollow beads 7, and the power motor 2-1 rotates the row of hollow beads 7 by clamping the bead chuck 2-2.

[0018] The bead guiding and positioning part includes: a guide tube 3-1, a positioning block 3-2, and a guide positioning bracket 3-3. The guide tube 3-1 is coaxially mounted on the guide positioning bracket 3-3 with the bead clamp 2-2 of the power head part. The positioning block 3-2 is threadedly connected to the guide positioning bracket 3-3 via a screw 3-21. The guide positioning bracket 3-3 is fixedly mounted on the slitting tool slide part.

[0019] Since the tube 7-1 held by the bead chuck 2-2 is in a cantilever position, in order to maintain the coaxiality of the tube 7-1 and the bead chuck 2-2, the cantilever end of the tube 7-1 is set in the guide tube 3-1, and the guide tube 3-1 ensures that the tube 7-1 and the bead chuck 2-2 rotate coaxially.

[0020] The slitting tool slide section includes: a pair of slitting blades 4-1, a pair of slitting blade shafts 4-2, a pair of slitting blade radial slide plates 4-3, an axial slide 4-4, a slitting blade radial control gear 4-5, a slitting blade radial control upper rack 4-6, a slitting blade radial control lower rack 4-7, and a gear control lever 4-8.

[0021] The slitting blade 4-1 is mounted on the slitting blade shaft 4-2, which is rotatably supported on the slitting blade radial slide plate 4-3. A pair of slitting blade radial slide plates 4-3 are horizontally and symmetrically mounted on the axial slide table 4-4 via dovetail guide rails. The slitting blade radial control gear 4-5 is rotatably supported on the axial slide table 4-4. One end of the gear control rod 4-8 is fixedly connected to the central shaft of the slitting blade radial control gear 4-5. The upper slitting blade radial control rack 4-6 and the lower slitting blade radial control rack 4-7 are respectively fixed on the pair of slitting blade radial slide plates 4-3. The upper rack 4-6 and the lower rack 4-7 of the slitting cutter radial control are respectively meshed with the upper and lower gears 4-5 of the slitting cutter radial control. The axial slide 4-4 is fixedly connected to the guide positioning bracket 3-3 of the bead material guide positioning part. The axial slide 4-4 is slidably connected to the sliding guide part.

[0022] This structure uses a pair of passive slitting blades 4-1 to cut the tube 7-1 by feeding into the tube through the radial slide plate 4-3. The cutting force of the slitting blade 4-1 is controlled by the contact pressure between the slitting blade 4-1 and the tube 7-1, which solves the technical defect of tube 7-1 being prone to deformation due to single-blade cutting, ensures the yield rate and can improve production efficiency.

[0023] The forward and reverse rotation of the radial control gear 4-5 of the slitting cutter is controlled by the gear control lever 4-8. The radial control gear 4-5 of the slitting cutter drives the upper radial control rack 4-6 and the lower radial control rack 4-7 of the slitting cutter to realize that the radial slide plate 4-3 of the slitting cutter drives the slitting cutter 4-1 to complete the cutting (cutting) or retraction.

[0024] The sliding guide part includes a guide rod 5-1 and a guide rod bracket 5-2. The guide rod bracket 5-2 is fixedly installed on the frame part 1, and the guide rod 5-1 is fixed on the guide rod bracket 5-2. The guide rod 5-1 and the axial slide 4-4 in the slitting tool slide part form a sliding connection with a shaft hole.

[0025] In this structure, the axial slide 4-4 of the slitting tool slide is moved by the gear control rod 4-8, so that the axial slide 4-4 drives the slitting tool 4-1 to move along the guide rod 5-1, so that the hollow beads 7-2 on the tube material 7-1 are cut one by one.

[0026] Meanwhile, the positioning block 3-2 of the ball guide and positioning part completes the axial limit of one end of the tube 7-1 to the axial slide 4-4. By adjusting the axial position of the positioning block 3-2 through the screw 3-21, the requirements for cutting hollow balls 7-2 of different sizes can be met.

[0027] In this embodiment of the utility model, the axial slide 4-4 of the slitting tool slide is fixedly provided with a slide plate limiting frame 6-1 and a limiting bolt 6-2. The limiting bolt 6-2 is threadedly connected to the slide plate limiting frame 6-1, and the limiting bolt 6-2 corresponds to the end face of the radial slide plate 4-3 of the slitting tool.

[0028] By adjusting the relative position of the radial slide plates 4-3 of the two slitting blades using the limiting bolts 6-2, synchronous slitting of a pair of slitting blades 4-1 can be achieved.

[0029] In this embodiment of the invention, an axial position adjusting nut 4-21 is provided on the slitting blade shaft 4-2 of the slitting blade slide. By adjusting the axial position of the two slitting blade shafts 4-2, the radial relative position of a pair of slitting blades 4-1 can be achieved. According to the slitting process requirements, the pair of slitting blades 4-1 can be radially aligned or staggered for slitting.
