The metal matrix 1 is provided with the mounting hole 3, the gem 2 is embedded in the mounting hole 3, the upper limiting ring 4 and the lower limiting ring 5 which are integrated with the metal matrix 1 are arranged in the mounting hole 3, the upper limiting ring 4 and the lower limiting ring 5 are integrated with the copper strip and are not installed after means such as welding, bonding and the like, the ornament can be more attractive due to the structure, the connecting part of the upper limiting ring 4 and the lower limiting ring 5 and the copper strip body is free of welding seams and burrs, and meanwhile, the cost for embedding the gem can be greatly reduced due to the structure. The gem can be various inlaid gemstones, and can also be zircon, glass, acrylic, crude stone, crystal diamond and the like. The upper limiting ring 4 and the lower limiting ring 5 are in two opposite truncated cone shapes, the two truncated cone-shaped limiting rings are buckled together in an inverted mode, the upper limiting ring 4 and the lower limiting ring 5 form the side faces of the truncated cones, the bottoms of the upper limiting ring 4 and the lower limiting ring 5 are integrally connected with the metal base, and the top faces of the truncated cones of the upper limiting ring 4 and the lower limiting ring 5 are open circular mouths. The inlaid jewel is mostly circular, and the limit ring in the shape of the circular truncated cone can better wrap up the jewel. The top surface of the round table is provided with an opening, so that the jewel can be exposed.

(1) a small hole is punched in the sheet metal base 1.

As shown in FIGS. 2 and 3, the sheet metal base 1 of the ornament is preferably made of a copper tape 7, such as H62-H65, having a thickness of 0.5mm-0.6mm, and having an infinite length, which can be continuously produced in a stamping apparatus. A single copper plate may also be used. As shown in fig. 4, the copper strip 7 is first introduced into a stamping die, and after positioning, a small hole 8 is punched in the copper strip 7 by a stamping pin 9. The size of the aperture 8 is determined by the diameter of the gemstone 2 to be inlaid, for example, the gemstone 2 to be inlaid may have a diameter of 2mm, and the aperture 8 may have a diameter of about 1.5-1.7 mm.

(2) A circle of metal matrix around the small hole 8 is bent and stretched upwards by using a bending column 10, so that an upright spacing ring 11 is formed near the small hole 7.

As shown in fig. 5, a bending column 10 is arranged at a punching position after punching a punching needle 9 of the small hole 8 on the punching die, preferably, the bending column 10 is arranged on a lower die 15, a pointed top is arranged at the top of the bending column 10, and the diameter of the bending column 10 is larger than that of the punching needle 9 for forming the small hole 8. The copper strips 7 continue forward on stamping equipment, the position of punching small hole 8 comes to buckle post 10 department, buckle post 10 and aim at the punching press of small hole 8, upwards jack-up the peripheral round copper sheet of small hole 8, go up and set up first spacing hole 13 on the mould 12 with buckle post 10 corresponding position, first spacing hole 13 diameter equals the thickness sum of buckling post 10 and copper strips 7, that is to say, when the mould closed, spacing ring 11 that buckles just in time crowds between first spacing hole 13 and the post 10 of buckling for near the formation of small hole 7 spacing ring 11 of erectting. At this time, the upper limit ring 4 and the lower limit ring 5 are not yet separated. The diameter of the bent post 10 is substantially equivalent to the diameter of the stone 2 to be mounted.

(3) And (3) punching the limiting ring by using the splitting punch 14 in the opposite direction, splitting the vertical limiting ring from the top, keeping the outer ring 11a of the limiting ring 11 on the upper side of the metal base body to form an open upper limiting ring 4, and bending the inner ring 11b of the limiting ring 11 to the lower side of the metal base body under the punching action of the splitting punch 14 to form a lower limiting ring 5 which is obliquely inwards folded.

After a circle of copper sheets around the small hole 8 are bent upwards to form the limiting ring 11 through the bending column 10, the copper belt 7 continuously enters a next punching position on punching equipment, and a splitting punch 14 is arranged on one side of the next punching position, which is opposite to the bending column 10, namely the splitting punch 14 is arranged on one side of the limiting ring 11, which is convex. Preferably, the bending cylinder 10 is disposed on the lower die 15 and the split punch 14 is disposed on the upper die 12. Of course, both the bending post 10 and the splitting punch could be provided on the upper die 12, but after the retainer ring is formed by the bending post, the copper strip would be reversed to use the splitting punch from the opposite direction to the bending post. The split punch 14 comprises a punch body 14a and a second limit hole 14b, a gap is arranged between the punch body 14a and the second limit hole 14b, the inner diameter of the second limit hole 14b is equivalent to the outer diameter of the raised limit ring 11, the outer diameter of the punch body 14a is larger than the inner diameter of the limit ring 11, because the inner diameter of the limit ring 11 is equal to the diameter of the bent column 10, that is, the outer diameter of the punch body 14a is slightly larger than the diameter of the bent column 10, the outer diameter of the punch body 14a is optimally equal to the diameter of the bent column 10 plus half of the thickness of the copper strip 7.

The post 10 of buckling can be fixed set up on the lower mould 15, like this when the post 10 of buckling is buckled the back with spacing ring 11, the copper strips 7 still overlaps tightly and can't break away from on the post 10 of buckling, can set up two elastic columns by the post 10 of buckling, when last mould 12 rose, the elastic column jack-up the copper strips, makes it break away from the post 10 of buckling to can continue to get into next punching press position forward on stamping die.

When the splitting punch 14 punches downwards, the edge of the punch body 14a contacts with the inner half-ring 11a of the limiting ring 11, as shown in fig. 6, the inner half-ring 11a of the limiting ring is squeezed downwards to split, so that the inner half-ring 11a and the outer half-ring 11b of the limiting ring are split, and the outer half-ring 11b of the limiting ring 11 is not squeezed downwards, and is kept upright on the upper side of the copper strip 7 under the action of the punch body 14a and the limiting sleeve 14b to form a circle of upright circular ring as the upper limiting ring 4; and the metal material of the inner half-ring 11a of the limiting ring 11 is downwards deformed under the extrusion of the punch body 14a and is bent to the lower side of the copper strip 7. The lower die 15 is provided with a conical concave hole 17 corresponding to the position of the splitting punch 14, and a obliquely inwardly-folded circular truncated cone is formed as the lower retainer ring 5 by the punch body 14a and the conical concave hole 17, as shown in fig. 7 and 8. The key point of the process for manufacturing the ornament is the step.

The second limit hole 14b can be replaced by a limit sleeve, the second limit hole 14b can be a round hole which is arranged on the die and has the diameter equivalent to that of the limit ring 11, and the limit sleeve refers to a round sleeve which is integrally connected with the punch body and moves along with the punch body and has the diameter equivalent to that of the limit ring. The first limiting hole can be replaced by a limiting sleeve. The two embodiments have no essential difference, as long as the copper strip 7 can be punched by the bending column 10 or the splitting punch 14, the outer side of the limiting ring 11 or the upper limiting ring 4 can be sleeved, and the limiting ring 11 or the upper limiting ring 4 is not deformed.

The inner half-ring 11a and the lower half-ring 5, and the outer half-ring 11b and the upper half-ring 4 of the retainer ring are referred to as the same parts, and the inner half-ring 11a and the outer half-ring 11b of the retainer ring are referred to as the inner half-ring 11a and the outer half-ring 11b of the retainer ring without splitting the inner half-ring 11a and the outer half-ring 11b of the retainer ring, and are referred to as the lower retainer ring 5 and the upper retainer ring 4 after splitting and bending the outer half-ring 11b below the copper strip 7.

The end of the punch body 14a may be set at a right angle or may be set at a chamfer 14 c. A large number of experiments prove that when the end part of the punch head is a chamfer, the limiting ring 11 is split, the splitting effect of the inner half ring 11a and the outer half ring 11b of the limiting ring is the best, the chamfer can be a beveling chamfer or an arc chamfer, and the beveling chamfer effect is better. When the end part of the punch body 14a is a chamfer angle, the shape of the end part of the punch body 14a is matched with the shape of the gem 2 to be embedded, and the lower limit ring 5 does not need to be adjusted to the desired shape after being punched in place; more importantly, the inner half ring 11a and the outer half ring 11b of the retainer ring are more smoothly split due to the shape, the upper retainer ring is less prone to deformation compared with the case that the end of the punch body is at a right angle, and the lower retainer ring 5 and the upper retainer ring 4 are more symmetrical. On the contrary, when the end of the punch body is at a right angle, the lower limit ring 5 and the upper limit ring 4 are easily asymmetric.

Because the width of the lower limit ring 5 may be larger, the opening of the truncated cone formed by the lower limit ring 5 is too small, and the exposed part of the inlaid jewel 2 is too small, so that the redundant part 5a needs to be removed by punching, and the requirement of the exposed area of the jewel is met. As shown in fig. 9 to 11, a conical recess 17 is provided at the next punching station, which recess is matched to the lower retainer ring 5 in shape, and a drain 18 is provided at the bottom of the conical recess 17, so that the excess punched from the lower retainer ring 5 can drain into the drain 18. Since the excess portion 5a punched out from the lower retainer ring 5 has a small volume weight, the chips may stick to the punch due to static electricity or the like. Therefore, a blowing passage 19 connected to the leak port 18 is provided in the lower die 15, the blowing passage 19 is connected to a blowing pipe 20, and the blowing pipe 20 is supplied with compressed air as shown in fig. 9 and 10. The high pressure air blows the chips away when the punch 21 punches the excess portion 5a of the lower retainer ring 5.

After the upper limiting ring 4 and the lower limiting ring 5 are formed by splitting the punch 14, the copper strip 7 continuously enters the next punching position on the punching equipment, and a punch capable of blanking the outline of the ornament is arranged on the next punching position. For example, a formed limit ring is taken as a center, a heart shape, a circle shape, a rain drop shape, a triangle shape, a flower shape and a pentagram shape are punched on a copper strip, various strip shapes can be punched according to requirements, and meanwhile, tying belt holes 22 for tying belts are punched, as shown in fig. 2, fig. 2 only punches the heart shape, so that a metal substrate of a small part unit for manufacturing the ornament is formed.

After the outline of the ornament is punched, the metal substrate of the small part unit is ground to remove burrs and ribs, and then the jewel is embedded as shown in figure 12.

When the jewel is inlaid, as shown in fig. 13, the ground metal substrate 1 is firstly placed on a press, a lower die 15 of the press is provided with a lower concave hole 23 matched with the lower limit ring 5, the metal substrate 1 is placed in the lower concave hole 23, then, as shown in fig. 14, the jewel 2 to be inlaid is placed, an upper concave hole 24 matched with the upper surface of the jewel 2 or the upper limit ring 4 is arranged at the corresponding position of an upper die 12 of the press, the press is started, the upper limit ring 4 with the opening extending in the vertical direction is pressed, as shown in fig. 15 and fig. 16, and is attached to the upper surface of the jewel 2, so that the jewel 2 is inlaid on the metal substrate 1, and the manufacturing process of the ornament of the present invention is completed.
