Description

Technical Field

[0001] The present invention relates to the field of metal forging technology, and in particular to a titanium alloy smart watch shell forging device and process. Background Art

[0002] Titanium alloys are often used in the manufacture of high-end smartwatch shells due to their light weight, high strength, corrosion resistance, and biocompatibility. When processing the metal shell of a smartwatch, a suitable sheet is usually selected first, and then the titanium alloy sheet is preliminarily formed through a forging process to make it close to the final size. Specifically, before forging, it is necessary to punch a hole at the dial installation position of the sheet, and then forge and expand the mounting hole of the dial through a forging head. The dimensional accuracy and shape accuracy of the hole diameter are improved by forging and expanding the hole, ensuring the roundness and flatness of the hole, and eliminating stress concentration at the edge of the hole through expansion, thereby improving the fatigue life and crack resistance of the watch case.

[0003] During the forging and hole expansion process, in order to prevent the forgings and forging punches from overheating and deformation, lubricating oil needs to be added in time to lubricate the forgings and forging punches. In the prior art, lubricating oil is mostly added manually or continuously added to the contact position of the forgings and the forging punches through a lubricating oil filling head. However, for smart watches of different specifications, the thickness of the plates used is not exactly the same. Thicker plates may need more lubricating oil to absorb heat during forging, while thinner plates require less lubricating oil during forging. The existing manual addition of lubricating oil or continuous addition of lubricating oil through a lubricating oil filling head is prone to excessive addition of too little or too much lubricating oil. Summary of the invention

[0004] Based on this, it is necessary to provide a titanium alloy smart watch case forging equipment and process to address the problems existing in the current forging equipment, so as to solve the problem that the amount of lubricating oil added during forging is difficult to accurately control, which easily leads to the problem of too little or too much lubricating oil added.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] The serial numbers of the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0044] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0045] like Figure 1-Figure 6 As shown, a titanium alloy smart watch case forging equipment includes an equipment body 100, a forging punch 200, an oil storage tank 300, a filling port 310 and a control component 400. The forging punch 200 is arranged on the equipment body 100, and the forging punch 200 can move in the vertical direction. The lower surface of the forging punch 200 is an inverted cone surface 210, and the side surface is an annular surface 220. The oil storage tank 300 is connected to the equipment body 100, and the oil storage tank 300 is filled with lubricating oil. The filling port 310 is arranged below the oil storage tank 300, and the filling port 310 is used to add lubricating oil to the contact position between the forging punch 200 and the workpiece 600. The control component 400 controls the amount of lubricating oil added to the contact position between the forging punch 200 and the workpiece 600 through the filling port 310, and the control component 400 is configured so that the amount of lubricating oil added is positively correlated with the downward movement distance of the forging punch 200.

[0046] When in use, the staff first punches a hole at the dial installation position of the workpiece 600 through the punching equipment, and then places the workpiece 600 on the forging platform of the equipment body 100 so that the center of the punched circular hole is located on the axis of the forging punch 200, and then moves the forging punch 200 downward in the vertical direction. When the forging punch 200 moves down until the forging punch 200 contacts the workpiece 600, as the forging punch 200 continues to move downward, the inverted cone surface of the forging punch 200 gradually expands the punched circular hole until the hole wall of the circular hole abuts against the side of the forging punch 200. When the lower part of the side of the forging punch 200 passes through the circular hole, the forging and hole expansion is completed. The control component 400 is configured so that the amount of lubricating oil added is positively correlated with the downward movement distance of the forging punch 200. Therefore, during the forging and expanding process, when the thickness of the workpiece 600 is relatively thick, the forging punch 200 completes the forging and expanding of the workpiece 600. The downward movement distance of the forging punch 200 is relatively large, and the amount of lubricating oil added is also large, which can absorb more heat and prevent the forging punch 200 and the workpiece 600 from overheating and deformation. When the thickness of the workpiece 600 is relatively thin, the forging punch 200 completes the forging and expanding of the workpiece 600. The downward movement distance of the forging punch 200 is relatively small, and the amount of lubricating oil added is also small, which can prevent the loss and waste of lubricating oil.

[0047] It is understandable that when the thickness of the workpiece 600 is thicker, the extrusion deformation of the workpiece 600 is greater during the forging and expanding process, and the friction between the workpiece 600 and the forging punch 200 is greater, so the heat generated is also greater. At this time, more lubricating oil is needed to absorb the generated heat and prevent the forging punch 200 and the workpiece 600 from overheating and deformation. On the contrary, when the thickness of the workpiece 600 is thinner, the extrusion deformation of the workpiece 600 is smaller during the forging and expanding process, and the friction between the workpiece 600 and the forging punch 200 is smaller, so the heat generated is also less, so a lot of lubricating oil is not needed to absorb the heat. At this time, if the amount of lubricating oil added is large, it will cause loss and waste.

[0048] In a further embodiment, Figure 2 and Figure 4 As shown, the control component 400 includes a holding ring 410 and a pressure valve 420. The holding ring 410 is arranged on the equipment body 100, and the holding ring 410 is located on the outside of the forging punch 200. The holding ring 410 can move in the vertical direction. The holding ring 410, the oil storage tank 300, the forging punch 200 and the workpiece 600 can circumferentially surround a first chamber 430. In the initial state, the air pressure in the first chamber 430 is a first preset value, and the oil pressure in the oil storage tank 300 is also a first preset value. The pressure valve 420 is arranged in the filling port 310. When the forging punch 200 moves downward in the vertical direction, the volume of the first chamber 430 increases, so that the pressure valve 420 opens, and the lubricating oil flows downward into the first chamber 430 through the filling port 310.

[0049] When in use, the staff first punches a hole at the dial installation position of the workpiece 600 through the punching equipment, and then places the workpiece 600 on the forging platform of the equipment body 100, so that the center of the punched circular hole is located on the axis of the forging punch 200, and then the holding ring 410 is moved downward in the vertical direction. After the holding ring 410 is pressed on the upper surface of the workpiece 600, the holding ring 410 stops moving downward, and then the forging punch 200 is moved downward in the vertical direction. As the forging punch 200 continues to move downward, the inverted cone surface of the forging punch 200 gradually expands the punched circular hole. When the wall of the circular hole abuts against the side of the forging punch 200, the holding ring 410, the oil storage tank 300, the forging punch 200 and the workpiece 600 circumferentially surround the first chamber 430. This is the initial state, and the air pressure in the first chamber 430 is a first preset value. The first preset value is one A standard atmospheric pressure. As the forging punch 200 continues to move downward, the volume of the first chamber 430 increases, and the air pressure in the first chamber 430 is less than a standard atmospheric pressure. At this time, the pressure valve 420 is forced to open, and the lubricating oil in the oil storage tank 300 flows into the first chamber 430, filling a partial area in the first chamber 430, so that the air pressure inside the first chamber 430 gradually increases. When the air pressure inside the first chamber 430 increases to equal the standard atmospheric pressure, the air pressure in the oil storage tank 300 is the same as the air pressure inside the first chamber 430, and the pressure valve 420 is forced to close. In this process, the lubricating oil gradually seeps down through the gap between the forging punch 200 and the workpiece 600 under the action of gravity, thereby absorbing the heat generated by the forging punch 200 and the workpiece 600 during the forging process through heat transfer, thereby preventing the forging punch 200 and the workpiece 600 from overheating and deformation.

[0050] It can be understood that the thicker the workpiece 600 is, the greater the distance the forging punch 200 moves downward when completing the forging and expanding the hole of the workpiece 600, thus making the volume increase of the first chamber 430 greater, and the amount of lubricating oil entering the first chamber 430 at this time is greater, which can absorb heat and prevent the workpiece 600 and the forging punch 200 from overheating and deformation; conversely, the thinner the workpiece 600 is, the smaller the distance the forging punch 200 moves downward when completing the forging and expanding the hole of the workpiece 600, thus making the volume increase of the first chamber 430 smaller, and the amount of lubricating oil entering the first chamber 430 at this time is less, thus reducing the consumption of lubricating oil and avoiding waste. In summary, the present invention sets a holding ring 410, an oil storage tank 300 and a pressure valve 420, and the holding ring 410, the oil storage tank 300, the forging punch 200 and the workpiece 600 circumferentially enclose a first chamber 430, and the volume increase of the first chamber 430 is positively correlated with the downward movement distance of the forging punch 200. Therefore, when the forging punch 200 performs forging and expanding the workpiece 600 of different thicknesses, adaptive addition of lubricating oil can be achieved, without the need for additional monitoring components, and the structure is simple and reliable.

[0051] In a further embodiment, Figure 3 and Figure 4 As shown, the oil storage tank 300 is slidably connected in the equipment body 100 , and the oil storage tank 300 is fixedly connected to the pressure holding ring 410 .

[0052] After the workpiece 600 is forged and expanded by the forging punch 200, the workpiece 600 needs to be forged and compacted to make the thickness of the workpiece 600 thinner and the density larger. Specifically, the staff keeps the position of the forging punch 200 unchanged, and then moves the oil storage tank 300 and the holding ring 410 downward synchronously. At this time, the volume of the first chamber 430 is reduced, and the lubricating oil in the first chamber 430 is squeezed into the gap between the holding ring 410 and the workpiece 600, thereby increasing the contact area between the lubricating oil and the holding ring 410 and the workpiece 600, so that the lubricating oil is distributed as evenly as possible on the surface of the holding ring 410 and the workpiece 600, thereby improving the heat absorption effect of the lubricating oil.

[0053] It should be further explained that, in order to allow the lubricating oil in the first chamber 430 to be squeezed into the gap between the holding ring 410 and the workpiece 600 when the volume of the first chamber 430 decreases, the volume of the first chamber 430 should be zero in the initial state, so that the lubricating oil can fill the first chamber 430, and when the volume of the first chamber 430 decreases, the lubricating oil in the first chamber 430 can be squeezed into the gap between the holding ring 410 and the workpiece 600. In addition, in this embodiment, the pressure valve 420 should be a one-way pressure valve 420, which restricts the lubricating oil in the first chamber 430 from flowing into the oil storage chamber, so that when the volume of the first chamber 430 decreases, the pressure valve 420 closes the filling port 310, and the lubricating oil can only be squeezed out through the gap between the holding ring 410 and the workpiece 600.

[0054] In a further embodiment, Figure 5 As shown, the titanium alloy smart watch case forging equipment also includes a locking component 500, which is arranged in the equipment body 100. The locking component 500 is used to stop the forging punch 200 after the forging punch 200 passes through the bottom of the workpiece 600, thereby limiting the forging punch 200 from moving in the vertical direction.

[0055] It is understandable that when the workpiece 600 is forged and consolidated by the holding ring 410, the friction between the workpiece 600 and the forging punch 200 increases. At this time, the workpiece 600 may be driven to move downward a short distance synchronously when being forged and consolidated, which will cause the volume of the first chamber 430 to be unable to be reduced. Therefore, it is necessary to stop the forging punch 200 by the locking assembly 500 after the forging punch 200 passes through the bottom of the workpiece 600 to limit the movement of the forging punch 200 in the vertical direction.

[0056] In a further embodiment, Figure 4-Figure 6 As shown, the locking assembly 500 includes a plurality of locking plates 510, and the plurality of locking plates 510 are arranged at equal intervals around the circumference of the forging punch 200. The plurality of locking plates 510 can approach or move away from each other along the radial direction of the forging punch 200. The locking assembly 500 also includes a plurality of first hydraulic rods, and the plurality of first hydraulic rods correspond one-to-one to the plurality of locking plates 510. The axis of the first hydraulic rod is horizontal, and the locking plate 510 is fixedly connected to the output end of the first hydraulic rod, and the fixed end of the first hydraulic rod is arranged on the equipment body 100.

[0057] In the initial state, the stopping plate 510 has a preset distance from the axis of the forging punch 200. After the forging punch 200 passes through the bottom of the workpiece 600, the forging punch 200 stops moving downward. Next, the first hydraulic rod is started, and the telescopic end of the first hydraulic rod drives the stopping plate 510 to approach each other along the radial direction of the forging punch 200. After the stopping plate 510 abuts against the forging punch 200 with a set pressure, the first hydraulic rod stops moving. At this time, the forging punch 200 is limited by the stopping plate 510 and cannot move. After the workpiece 600 is forged and compacted by the holding ring 410, the telescopic end of the first hydraulic rod first drives the retaining plate 510 to move away from each other in the radial direction of the forging punch 200, so that the retaining plate 510 is reset to the initial position, and then the forging punch 200 is moved upward in the vertical direction. Finally, the holding ring 410 drives the oil storage tank 300 to move upward synchronously, so that the holding ring 410 and the oil storage tank 300 are reset to the initial position. At this time, the workpiece 600 can be removed from the equipment body 100.

[0058] In a further embodiment, a second hydraulic rod is further provided inside the equipment body 100 , a telescopic end of the second hydraulic rod is fixedly connected to the forging punch 200 , and a fixed end of the second hydraulic rod is arranged on the equipment body 100 .

[0059] When the forging punch 200 needs to move in the vertical direction, the second hydraulic rod is started, and the telescopic end of the second hydraulic rod drives the forging punch 200 to move. In addition, the second hydraulic rod can also be replaced by a cylinder or other linear drive mechanism to drive the forging punch 200 to move in the vertical direction.

[0060] In a further embodiment, a third hydraulic rod is further provided inside the equipment body 100 , and the telescopic end of the third hydraulic rod is fixedly connected to the holding ring 410 .

[0061] When the forging punch 200 needs to move in the vertical direction, the third hydraulic rod is started, and the telescopic end of the third hydraulic rod drives the holding ring 410 to move. In addition, the third hydraulic rod can also be replaced by a cylinder or other linear drive mechanism to drive the holding ring 410 to move in the vertical direction.

[0062] In a further embodiment, a liquid filling port is further provided on the outside of the equipment body 100 , and the liquid filling port is connected to the oil storage tank 300 for replenishing lubricating oil into the oil storage tank 300 .
