Description

Technical Field

[0001] This invention relates to the technical field of jewelry processing, and in particular to a method for manufacturing earrings and its application. Background Technology

[0002] In the earring manufacturing process, a semi-circular blank is first processed, followed by further cutting and drilling. The processed blanks are then assembled to obtain the finished earring. Currently, the raw material used for processing the semi-circular blank is a 2m long, semi-circular groove-shaped die-cast profile (see...). Figure 6 The blank, with a semi-circular cross-section, is cut along the length of the semi-circular groove profile according to the required width during processing to obtain a semi-circular blank. Because the width range of the blanks required for earring production is relatively small, typically 1.0-8.0 cm, cutting is difficult and prone to inaccurate cutting, resulting in too many defective blanks and significant waste. To reduce raw material waste and the defect rate of blanks, it is necessary to change the blank processing method and develop a new earring manufacturing method with low waste and high yield. Summary of the Invention

[0003] The purpose of this invention is to provide a method for manufacturing earrings and their application.

[0004] According to one aspect of the present invention, a method for manufacturing an earring is provided, comprising the following steps:

[0005] S1. Install an arc-shaped mold on the feeding machine. The wire feed is bent into an arc shape by the arc-shaped mold. The feeding knife cuts the wire exposed from the mold. The blank falls out of the mold. The cut wire continues to enter the arc-shaped mold, is bent, and then cut. Repeat the above process to prepare multiple blanks of the same shape and size.

[0006] S2. Take a portion of the blank and cut and drill both ends of it to prepare multiple first half-rings. Each first half-ring is provided with a hinge groove and a first snap-fit ​​end.

[0007] S3. Take a portion of the blank and cut and drill both ends of it to prepare multiple second half-rings. The second half-rings are provided with insert arms and second snap-fit ​​ends.

[0008] S4. Insert the insert arm of the second half-ring into the hinge groove of the first half-ring and hinge it.

[0009] S5. Insert both ends of the pin into the first snap-fit ​​end and the second snap-fit ​​end respectively, and assemble the first half ring and the second half ring accordingly to obtain the finished earring.

[0010] In some embodiments, the cross-section of the wire is rectangular, square, triangular, semi-circular, or circular, the wire is stainless steel, and the inner diameter of the finished earring is 3.0-48mm.

[0011] In some embodiments, when the cross-section of the wire is rectangular or square, the width of the wire is 1.0-8.0 mm, the thickness of the wire is 1.5-3.0 mm, and the inner diameter of the finished earring made from the wire is 3.0-29 mm.

[0012] In some embodiments, when the cross-section of the wire is circular or semi-circular, the wire diameter is 1.2-8.0 mm, and the inner diameter of the finished earring made from the wire is 6.0-48 mm.

[0013] In some embodiments, when the cross-section of the wire is triangular, the width of the wire is 2.0-8.0 mm, the thickness of the wire is 1.2-10 mm, and the inner diameter of the finished earring made from the wire is 6.0-48 mm.

[0014] In some embodiments, the mold is a semi-circular mold with a groove inside for accommodating the wire.

[0015] In some embodiments, step S2: take a portion of the blank and cut one end to form a hinge groove and hinge arms symmetrically distributed on both sides of the hinge groove. Drill holes in the two hinge arms to form two first hinge holes corresponding to the positions. Then cut the other end to form a first snap-fit ​​end. Then drill holes in the end face of the first snap-fit ​​end to form a first snap-fit ​​hole, thus preparing the first half ring.

[0016] In some embodiments, step S3: take a portion of the blank and cut one end to form an insert arm, drill a hole in the insert arm to form a second hinge hole, then cut the other end to form a second snap-fit ​​end, then drill a hole in the end face of the second snap-fit ​​end to form a second snap hole, thus preparing the second half ring.

[0017] In some implementations, the hinge slot is matched to the size and shape of the insert arm, and after the insert arm is inserted into the hinge slot, the positions of the first hinge hole and the second hinge hole correspond.

[0018] In some embodiments, the pin connector is arc-shaped and has a fixed end, a notch, and a locking end. The notch is located between the fixed end and the locking end and is adjacent to the locking end. The end face of the locking end is elliptical, and the width of the locking end gradually increases along the end face of the locking end towards the notch.

[0019] In some embodiments, the fixed end is inserted into the first locking hole and fixedly connected to the first half-ring, the locking block end is inserted into the second locking hole and detachably locked to the second locking hole, and the notch is located on the outside of the second locking hole.

[0020] According to another aspect of the present invention, an earring manufacturing method is provided for use in the processing of earrings.

[0021] The beneficial effects of this invention are as follows: This invention uses profiles with cross-sectional shapes and sizes that meet the requirements to replace semi-circular groove profiles. Only by bending the profiles into a semi-circular shape and then cutting them can qualified blanks be obtained. The size of the blanks is limited by the semi-circular mold, which improves the cutting accuracy. Moreover, the size of the cutting surface is much smaller than that of the semi-circular groove profile, and its cutting difficulty is also much lower than that of the semi-circular groove profile. The loss is reduced by 35%, and the blank qualification rate is increased by 34.5%, which greatly improves the blank processing efficiency and the yield rate. It is very suitable for earring processing. Attached Figure Description

[0028] The present invention will be further described in detail below through specific implementation examples. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. After reading this invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims. Unless otherwise specified, all raw materials and reagents of the present invention are commercially available.

[0029] Example 1

[0030] A method for manufacturing an earring includes the following steps:

[0031] S1. Install a semi-circular mold on the feeding machine. The semi-circular mold has a groove inside to accommodate the wire, which facilitates bending of the square stainless steel wire. The square stainless steel wire with a width of 1.0-8.0mm and a thickness of 1.5-3.0mm is fed into the semi-circular mold and bent into a semi-circle. The feeding knife cuts the wire exposed from the mold, and the blank falls out of the mold. The cut wire continues to enter the semi-circular mold to be bent and then cut. The above process is repeated continuously to prepare multiple semi-circular blanks with the same shape and size. The two ends of the semi-circular blanks are square.

[0032] S2. Reference Figure 5 ( Figure 5 The shaded part in the image represents the part to be cut. A portion of the semi-circular blank is cut at one end to form a hinge groove and hinge arms symmetrically distributed on both sides of the hinge groove. Holes are drilled in the two hinge arms to form two corresponding first hinge holes. Then, the other end is cut to form a first snap-fit ​​end. Holes are drilled in the end face of the first snap-fit ​​end to form the first snap-fit ​​hole, thus obtaining the first semi-circle.

[0033] S3. Reference Figure 5 Take a portion of the semi-ring-shaped blank and cut one end to form an insert arm. The size and shape of the insert arm match the hinge groove. Drill a hole in the insert arm to form a second hinge hole. Then cut the other end to form a second snap-fit ​​end. Drill a hole on the end face of the second snap-fit ​​end to form a second snap-fit ​​hole, thus preparing the second semi-ring.

[0034] S4. Insert the insert arm of the second half ring into the hinge groove of the first half ring, so that the positions of the first hinge hole and the second hinge hole correspond, and insert bolts into the first hinge hole and the second hinge hole to hinge the insert arm and the two hinge arms.

[0035] S5. Insert the fixed end and the locking end of the pre-processed arc-shaped pin connector, which has a fixed end, a notch, and a locking block end, into the first locking hole of the first locking end and the second locking hole of the second locking end, respectively. The widest part of the locking block end is detachably locked to the inner wall of the second locking hole. The notch is located on the outside of the second locking hole. The fixed end is fixedly connected to the first locking hole. This completes the corresponding assembly of the first half ring and the second half ring, resulting in a finished earring with an inner diameter of 3.0-29mm.

[0036] The manufacturing method of this invention uses square wire with a cross-sectional size that meets the requirements instead of semi-circular groove profiles. By limiting the size of the blank through a semi-circular mold, the cutting accuracy is improved. A qualified blank can be obtained simply by bending the square profile into a semi-circular shape and then cutting it. Moreover, the cutting surface of the square profile is square, and its size is much smaller than the semi-circular cutting surface of the semi-circular groove profile. Its cutting difficulty is also much lower than that of the semi-circular groove profile, which reduces the loss of blank processing by 35% and increases the blank qualification rate by 34.5%. This greatly improves the blank processing efficiency and the yield rate, and is very suitable for earring processing.

[0037] Reference Figure 1 and Figure 2 The finished earring prepared in this embodiment includes a first half-ring 1, a second half-ring 2, and a pin connector 3. The first half-ring 1 has a hinge groove, two hinge arms 11, and a first locking end 12. The two hinge arms 11 are symmetrically distributed on both sides of the hinge groove. Each of the two symmetrically distributed hinge arms 11 has a first hinge hole 13, and the positions of the two hinge holes 13 are consistent. The end face of the first locking end 12 has a first locking hole 14 for fixing the fixing end of the pin connector 3. The second half-ring 2 has an insert arm 21 and a second locking end 22. The shape and size of the insert arm 21 are matched with the hinge groove. The insert arm 21 has a second hinge hole 23. When the insert arm 21 is inserted into the hinge groove, the position of the second hinge hole 23 is consistent with the position of the two first hinge holes 13, which facilitates the insertion of a bolt 4 to hinge the hinge arm 11 to the insert arm 21. The end face of the second snap-fit ​​end 22 is provided with a second snap-fit ​​hole 24 for the snap-fit ​​end 33 of the detachable snap-fit ​​pin connector 3.

[0038] The pin connector 3 is arc-shaped and has a fixed end 31, a notch 32, and a locking end 33. The notch 32 is an annular notch located between the fixed end 31 and the locking end 33, and is adjacent to the locking end 33. The end face of the locking end 33 is elliptical, and its width gradually increases along the direction of the notch 32. During assembly, the fixed end 31 is inserted into the first locking hole 14 and fixedly engaged with it. The locking end 33 is inserted into the second locking hole 24, and its widest point is detachably engaged with the inner wall of the second locking hole 24. The notch is located on the outside of the second locking hole 24. By setting the notch 32, the locking end 33 can be detachably engaged in the second locking hole 24, making it easy to remove the locking end 33 from the second locking hole 24 when needed, so that the pin connector 3 can be separated from the second half-ring 2 and the earring can be opened.

[0040] A method for manufacturing an earring includes the following steps:

[0041] S1. Install a semi-circular mold on the feeding machine. The semi-circular mold has a groove for accommodating wire, which facilitates bending of stainless steel wire with a semi-circular cross-section. The semi-circular stainless steel wire with a diameter of 1.2-8.0mm is fed into the semi-circular mold and bent into a semi-circular shape. The feeding knife cuts off the wire protruding from the mold, and the blank falls out of the mold. The cut semi-circular stainless steel wire continues to enter the semi-circular mold, is bent, and then cut. The above process is repeated continuously to prepare multiple semi-circular blanks with the same shape and size.

[0042] S2. Reference Figure 5 ( Figure 5 The shaded part in the image represents the part to be cut. A portion of the semi-circular blank is cut at one end to form a hinge groove and hinge arms symmetrically distributed on both sides of the hinge groove. Holes are drilled in the two hinge arms to form two corresponding first hinge holes. Then, the other end is cut to form a first snap-fit ​​end. Holes are drilled in the end face of the first snap-fit ​​end to form the first snap-fit ​​hole, thus obtaining the first semi-circle.

Insert the fixed end and the locking end of the pre-processed arc-shaped pin connector with a fixed end, a notch, and a locking block end into the first locking hole of the first locking end and the second locking hole of the second locking end, respectively. The widest part of the locking block end is detachably locked to the inner wall of the second locking hole. The notch is located outside the second locking hole. The fixed end is fixedly connected to the first locking hole, thus completing the corresponding assembly of the first half ring and the second half ring, and obtaining the finished earring. The inner diameter of the finished earring is 6.0-48mm. The specific structure of the finished earring differs from that of Example 1 in that: (1) the specific shape of the notch of the pin connector is different.
