[0033] like Figures 1 to 7 As shown, it is a precious metal bracelet shaping machine 100 shown in the present invention, which is used to squeeze and flatten the surface of the bracelet.

[0034] like Figure 1 As shown, the precious metal bracelet shaping machine 100 includes: a rotating mechanism 10, a driving mechanism 20 and a shaping mechanism 30, wherein the rotating mechanism 10 is used to install the bracelet and control the rotation of the bracelet, the driving mechanism 20 is used to control the shaping mechanism 30 to squeeze the bracelet to squeeze the surface of the bracelet flat, and the bracelet is controlled to rotate by the rotating mechanism 10. The driving mechanism 20 and the shaping mechanism 30 cooperate to make the shaping mechanism 30 squeeze the surface of the bracelet, which is conducive to flattening the concave and convex surfaces of the bracelet surface, making the surface of the bracelet flat, and facilitating the polishing of the bracelet surface, thereby achieving the purpose of improving the polishing effect.

[0035] Below, combined Figures 1 to 7 , the above-mentioned precious metal bracelet shaping machine 100 is further explained.

[0036] like Figure 1 and Figure 2 As shown, the rotating mechanism 10 includes a driving member 11, a tensioning member 12, a three-grabbing cylinder 13, a roller clamping member 14 and a transmission belt (not shown in the figure), wherein the number of the roller clamping members 14 is three, and the three roller clamping members 14 are rotatably installed on the three-grabbing cylinder 13, and the three-grabbing cylinder 13 controls each roller clamping member 14 to approach or move away from each other to clamp the bracelet. The transmission belt uses the tensioning member 12 to maintain a transmission connection with the driving member 11 and each roller clamping member 14 to drive each roller clamping member 14 to rotate, thereby realizing the control of the rotation of the bracelet installed on the roller clamping member 14.

[0037] like Figure 1 and Figure 3As shown, the driving mechanism 20 includes a longitudinal driving assembly 21 , a lifting driving assembly 22 , a transverse driving assembly 23 and a rotation driving assembly 24 which are connected in sequence, and the rotation driving assembly 24 is connected to the correction assembly 32 . Specifically, with the rotation axis of the bracelet as a reference, a first direction F1, a second direction F2 and a third direction F3 that are perpendicular to each other are constructed. The driving component drives the lifting driving component 22 to move along the first direction F1, the lifting driving component 22 drives the transverse driving component 23 to move along the second direction F2, the transverse driving component 23 drives the rotation driving component 24 to move along the third direction F3, and the rotation driving component 24 drives the correction component 32 to rotate around the third direction F3. Among them, the longitudinal driving component 21, the lifting driving component 22 and the transverse driving component 23 are all screw modules, and the rotation driving component 24 is a motor. Through the cooperation of the longitudinal driving component 21, the lifting driving component 22 and the transverse driving component 23, it is convenient to control the shaping mechanism 30 connected to the rotation driving component 24 to approach or move away from the bracelet, so as to realize the control of the shaping mechanism 30 to be combined with or separated from the bracelet. The shaping mechanism 30 is driven to rotate around the third direction F3 by the rotation driving component 24, which is convenient to control the shaping mechanism 30 to contact with the bracelet around the third direction F3, so as to shape part of the surface of the bracelet, thereby achieving the purpose of improving the shaping efficiency.

[0038] For example, during shaping, the bracelet is controlled to enter the correction space 33 through the cooperation of the longitudinal drive component 21, the lifting drive component 22 and the transverse drive component 23, and then the correction space 33 of the shaping mechanism 30 is driven to rotate 90 degrees around the bracelet's arm by utilizing the cooperation of the longitudinal drive component 21, the lifting drive component 22, the transverse drive component 23 and the rotation drive component 24. The two correction components 32 are used to shape the surfaces of the relative angles of the bracelet's arm respectively, and then the bracelet is controlled to rotate 90 degrees around the second direction F2, and then installed on the rotating mechanism 10 again, and the above shaping steps are repeated to achieve surface shaping of the bracelet.

[0039] like Figure 1 、 Figure 3 and Figure 4 As shown, the shaping mechanism 30 includes a base 31 and a correction component 32. There are two correction components 32. The two correction components 32 are both installed on the base 31 and are separated to form a correction space 33. The rotating drive component 24 of the drive mechanism 20 is connected to the base 31 and drives the correction space 33 to be combined with or separated from the bracelet.

[0040] Specifically, if Figure 4 and Figure 6As shown, the correction component 32 includes a mounting block 321, a rotating member 322 and a correction rod 323. The mounting block 321 is installed on the base 31, and the correction rod 323 is rotatably installed on the mounting block 321 through the rotating member 322. The correction rod 323 is used to contact the bracelet. The correction rod 323 contacts the bracelet through the rotating correction rod 323, which is beneficial for the correction rod 323 to rotate relative to the bracelet when it contacts the rotating bracelet, thereby reducing the friction between the correction rod 323 and the bracelet, so as to reduce the loss of the bracelet during shaping. Among them, the correction rod 323 can be made of a ceramic material with high hardness, strength and wear resistance, such as white corundum. White corundum not only has good hardness, strength and wear resistance, but also is resistant to high temperatures and has good toughness. In the process of contact with the precious metal bracelet, it is beneficial to avoid the temperature affecting the deformation of the correction rod 323, so as to achieve the purpose of improving the shaping quality.

[0041] In this embodiment, if Figure 6 As shown, there are two rotating parts 322, and the two rotating parts 322 are installed at intervals on the mounting block 321. The correction rod 323 is movably passed through the mounting block 321 and is connected to the two rotating parts 322, wherein the rotating part 322 is a bearing. Specifically, the mounting block 321 is provided with a bearing groove 324 and a movable hole 325, and the rotating part 322 is installed in the bearing groove 324. The correction rod 323 is passed through the movable hole 325 and is connected to each rotating part 322. The two rotating parts 322 are used to facilitate the improvement of the concentricity of the correction rod 323 during rotation, so as to improve the shaping accuracy.

[0042] Furthermore, if Figure 4 and Figure 6 As shown, the end of the correction rod 323 away from the mounting block 321 has a tapered surface 326, which helps guide the bracelet into the correction space 33 and prevents the correction rod 323 from hitting the bracelet.

[0043] like Figure 5 As shown, the base 31 includes a base body 311, a fixed block 312, a guide rod 313 and an elastic member 314. The base body 311 is connected to the driving mechanism 20. There are two fixed blocks 312, and the two fixed blocks 312 are installed on the base body 311. The guide rod 313 is connected to each fixed block 312. The mounting block 321 of the correction component 32 is slidably set on the guide rod 313. There are multiple elastic members 314, and each elastic member 314 drives the mounting blocks 321 of each correction component 32 to approach each other. The elastic member 314 is a spring and is sleeved on the guide rod 313 and is located between the fixed block 312 and the mounting block 321 of the correction component 32.

[0044] By driving the mounting blocks 321 of each correction component 32 closer to each other through the elastic member 314, it is possible to effectively avoid rigid contact between the correction rod 323 of the correction component 32 and the bracelet, reduce stress concentration at the contact portion between the correction rod 323 of the correction component 32 and the bracelet, and thereby effectively avoid local damage and breakage of the bracelet during the shaping process. Furthermore, there are two guide rods 313, which are conducive to improving the guiding accuracy.

[0045] Furthermore, if Figure 4 and Figure 5 As shown, the seat body 311 is provided with a guide groove 315, and the mounting block 321 of the correction component 32 is movably arranged in the guide groove 315. The guide groove 315 is conducive to improving the movement accuracy of the correction component 32, so as to achieve the purpose of improving the shaping accuracy of the correction component 32.

[0046] Furthermore, the base 31 also includes a limiting component 34 installed on the seat body 311. The limiting component 34 is arranged between the mounting blocks 321 of the two correction components 32 and abuts against the mounting block 321 of one of the correction components 32. By abutting the limiting component 34 against the mounting block 321 of the correction component 32, it is helpful to avoid the correction rod 323 of the correction component 32 from over-squeezing the bracelet after shaping it into a predetermined shape, thereby improving the shaping accuracy of the bracelet.

[0047] In this embodiment, there are two limit assemblies 34, and the two limit assemblies 34 are respectively abutted against the mounting blocks 321 of each correction assembly 32. By abutting the two limit assemblies 34 against the mounting blocks 321 of the correction assembly 32, it is beneficial to effectively control the range of the correction space 33, thereby avoiding excessive squeezing of the correction rod 323 of the correction assembly 32.

[0048] like Figure 4 and Figure 5 As shown, the seat body 311 is provided with a scale mark 35 at the position corresponding to the limit assembly 34, and the scale mark 35 is used to improve the position adjustment accuracy of the limit assembly 34.

[0049] like Figure 7 As shown, the limiting assembly 34 includes a limiting plate 341, an adjusting member 342, and an adapter 343. The limiting plate 341 is arranged between the mounting blocks 321 of the two correction assemblies 32. The adjusting member 342 passes through the limiting plate 341 and is connected to the adapter 343. The adapter 343 is slidably arranged on the base 311.

[0050] Specifically, the limit plate 341 is provided with a sliding hole 344 that is slidably connected to each guide rod 313. The limit plate 341 can cooperate with the guide rod 313 through the sliding hole 344 to increase the support of the limit plate 341 using the guide rod 313, thereby effectively improving the limiting accuracy of the limit plate 341.

[0051] Among them, the adjusting part 342 can be selected as a screw, and the adapter 343 can be selected as a sliding groove nut or a profile nut that cooperates with the adjusting part 342. A guide groove 316 for the adapter 343 to slide is provided on the base body 311. Through the cooperation between the adjusting part 342 and the adapter 343, it is convenient to control the position of the limit plate 341 fixed on the base body 311, thereby realizing the adjustment of the position between the two correction components 32.

[0052] The working principle of the precious metal bracelet shaping machine 100 described in the present invention is: the bracelet is installed through the rotating mechanism 10 to control the rotation of the bracelet, the driving mechanism 20 controls the base 31 of the shaping mechanism 30 to be close to the bracelet, so that the bracelet enters the correction space 33, the driving mechanism 20 cooperates with the shaping mechanism 30, and uses the correction component 32 to squeeze the bracelet and flatten the concave and convex surfaces of the bracelet surface, thereby realizing the surface shaping of the bracelet. The shaped bracelet is conducive to polishing and can effectively improve the polishing effect.

[0053] The beneficial effects of the precious metal bracelet shaping machine 100 described in the present invention are: the rotating mechanism 10 is used to control the rotation of the bracelet, and the driving mechanism 20 and the shaping mechanism 30 are used to cooperate so that the correction component 32 squeezes the bracelet surface in the correction space 33, which is conducive to flattening the concave and convex surfaces of the bracelet surface. The flat surface of the bracelet is conducive to polishing, thereby achieving the purpose of effectively improving the polishing effect.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
