Description

Technical Field

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

[0002] Due to its characteristics such as light weight, high strength, corrosion resistance, and biocompatibility, titanium alloy is often used in the manufacture of the shells of high-end smart watches. When processing the metal shell of a smart watch, usually a suitable sheet is selected first, and then the titanium alloy sheet is initially formed through a forging process to make it close to the final outer dimension. Specifically, before forging, it is necessary to punch holes at the dial installation position of the sheet first, and then the forging head is used to perform forging and reaming on the installation holes of the dial. By forging and reaming, the dimensional accuracy and shape accuracy of the hole diameter are improved, the roundness and flatness of the hole are ensured, and the stress concentration at the hole edge is eliminated through reaming, thereby improving the fatigue life and crack resistance of the watch shell.

[0003] During the process of forging and reaming, in order to prevent the forgings and the forging punch from overheating and deforming, it is necessary to add lubricating oil in time to lubricate the forgings and the forging punch. In the prior art, most of the lubricating oil is manually added or continuously added to the contact position of the forgings and the forging punch through a lubricating oil filling head. However, for smart watches of different specifications, the thickness of the used sheets is not exactly the same. Thicker sheets may require more lubricating oil to absorb heat during forging, while thinner sheets require less lubricating oil during forging. The existing form of manually adding lubricating oil or continuously filling lubricating oil through a lubricating oil filling head is likely to cause the added amount of lubricating oil to be too little or too much. Summary of the Invention

[0004] Based on this, in view of the problems existing in the current forging equipment, it is necessary to provide a forging device and process for the shell of a titanium alloy smart watch to solve the problem that it is not easy to accurately control the added amount of lubricating oil during forging, which is likely to cause the added amount of lubricating oil to be too little or too much.

[0005] The above object is achieved through the following technical solutions:

[0006] A forging device for the shell of a titanium alloy smart watch, used for forging workpieces, includes:

[0007] The device main body;

[0008] A forging punch, which is arranged on the device main body and can move in the vertical direction. The lower surface of the forging punch is an inverted conical surface, and the side surface is an annular surface;

[0009] An oil storage tank, which is connected to the inside of the device main body and is filled with lubricating oil;

[0010] The filling port is arranged below the fuel tank and is used to fill lubricating oil at the contact position between the forging punch and the workpiece.

[0011] The control component controls the amount of lubricating oil filled through the filling port at the contact position between the forging punch and the workpiece, and the control component is configured such that the filling amount of the lubricating oil is positively correlated with the downward movement distance of the forging punch.

[0012] In one embodiment, the control component includes a pressing ring and a pressure valve. The pressing ring is arranged on the equipment main body and is located outside the forging punch. The pressing ring can move in the vertical direction. The pressing ring, the fuel tank, the forging punch, and the workpiece can circumferentially enclose a first chamber. In the initial state, the air pressure in the first chamber is a first preset value, and the oil pressure in the fuel tank is also a first preset value.

[0013] The pressure valve is arranged in the filling port.

[0014] When the forging punch moves downward in the vertical direction, the volume of the first chamber increases, so that the pressure valve opens, and the lubricating oil flows downward through the filling port into the first chamber.

[0015] In one embodiment, the fuel tank is slidably connected in the equipment main body and is fixedly connected to the pressing ring.

[0016] In one embodiment, the forging equipment for the titanium alloy smart watch case further includes a locking component arranged in the equipment main body. The locking component is used to lock and limit the forging punch after the forging punch passes through the bottom of the workpiece, restricting the forging punch from moving in the vertical direction.

[0017] In one embodiment, the locking component includes a plurality of locking plates arranged at equal intervals around the circumference of the forging punch. The plurality of locking plates can approach or move away from each other in the radial direction of the forging punch.

[0018] In one embodiment, the locking component further includes a plurality of first hydraulic rods corresponding to the plurality of locking plates one by one. The axis of the first hydraulic rod is horizontal, and the locking plate is fixedly connected to the output end of the first hydraulic rod. The fixed end of the first hydraulic rod is arranged on the equipment main body.

[0019] In one embodiment, a third hydraulic rod is further arranged inside the equipment main body, and the telescopic end of the third hydraulic rod is fixedly connected to the pressing ring.

[0020] In one embodiment, a second hydraulic rod is further arranged inside the equipment main body, and the telescopic end of the second hydraulic rod is fixedly connected to the forging punch.

[0021] In one embodiment, a liquid filling port is further provided on the outside of the device body. The liquid filling port is communicated with the oil storage tank and is used to supplement lubricating oil into the oil storage tank.

[0022] A forging process for the titanium alloy smart watch case uses the forging equipment for the titanium alloy smart watch case described above and includes the following steps:

[0023] S1: Place the workpiece so that the center of the pre-punched round hole of the workpiece is located on the axis of the forging punch.

[0024] S2: Make the lower part of the side of the forging punch pass through the round hole.

[0025] S3: Limit the forging punch through the locking component to restrict the forging punch from moving in the vertical direction.

[0026] S4: Make the pressing ring and the oil storage tank move downward synchronously to forge and compact the workpiece.

[0027] S5: Cancel the limit on the forging punch by the locking component and reset the locking component.

[0028] S6: Make the forging punch move upward to reset.

[0029] S7: Make the pressing ring and the oil storage tank move upward to reset.

[0030] S8: Remove the workpiece from the device body.

[0031] S9: Loop through S1 - S8.

[0032] The beneficial effects of the present invention are:

[0033] By setting the pressing ring, the oil storage tank and the pressure valve, the first chamber is enclosed circumferentially by the pressing ring, the oil storage tank, the forging punch and the workpiece, and the increase in the volume of the first chamber is positively correlated with the downward movement distance of the forging punch. Therefore, when the forging punch expands the hole of workpieces with different thicknesses, the self - adaptive addition of lubricating oil can be realized without additionally setting monitoring components, and the structure is simple and reliable.

[0045] AsFigures 1-6 As shown in Figures 1-6 , a forging and pressing device for a titanium alloy smart watch case includes a device main body 100, a forging and pressing punch 200, an oil storage tank 300, a filling port 310, and a control component 400. The forging and pressing punch 200 is arranged on the device main body 100 and can move in the vertical direction. The lower surface of the forging and pressing punch 200 is an inverted conical surface 210, and the side surface is an annular surface 220. The oil storage tank 300 is connected inside the device main body 100, and lubricating oil is contained in the oil storage tank 300. The filling port 310 is arranged below the oil storage tank 300, and the filling port 310 is used to fill lubricating oil at the contact position between the forging and pressing punch 200 and the workpiece 600. The control component 400 controls the amount of lubricating oil filled through the filling port 310 at the contact position between the forging and pressing punch 200 and the workpiece 600, and the control component 400 is configured such that the filling amount of the lubricating oil is positively correlated with the downward movement distance of the forging and pressing punch 200.

[0046] During use, the staff first punches a hole at the dial installation position of the workpiece 600 through a punching device, and then places the workpiece 600 on the forging platform of the device main body 100, so that the center of the punched round hole is located on the axis of the forging and pressing punch 200. Then, the forging and pressing punch 200 is moved downward in the vertical direction. When the forging and pressing punch 200 moves downward until it contacts the workpiece 600, as the forging and pressing punch 200 continues to move downward, the inverted conical surface of the forging and pressing punch 200 gradually expands the punched round hole until the hole wall of the round hole abuts against the side surface of the forging and pressing punch 200. When the lower part of the side surface of the forging and pressing punch 200 passes through the round hole, the forging and hole expanding is completed at this time. Since the control component 400 is configured such that the filling amount of the lubricating oil is positively correlated with the downward movement distance of the forging and pressing punch 200, during the forging and hole expanding process, when the thickness of the workpiece 600 is relatively thick, when the forging and pressing punch 200 completes the forging and hole expanding of the workpiece 600, the downward movement distance of the forging and pressing punch 200 is relatively large, and the filling amount of the lubricating oil is also relatively large, which can absorb more heat and prevent the forging and pressing punch 200 and the workpiece 600 from overheating and deforming. When the thickness of the workpiece 600 is relatively thin, when the forging and pressing punch 200 completes the forging and hole expanding of the workpiece 600, the downward movement distance of the forging and pressing punch 200 is relatively small, and the filling amount of the lubricating oil is also relatively small, which can prevent waste of lubricating oil.

[0047] It can be understood that when the thickness of the workpiece 600 is relatively thick, the extrusion deformation amount of the workpiece 600 during the forging and reaming process is larger, and the frictional force between the workpiece 600 and the forging punch 200 is greater. Therefore, more heat is generated. At this time, more lubricating oil is required to absorb the generated heat and prevent the forging punch 200 and the workpiece 600 from overheating and deforming. On the contrary, when the thickness of the workpiece 600 is relatively thin, the extrusion deformation amount of the workpiece 600 during the forging and reaming process is smaller, and the frictional force between the workpiece 600 and the forging punch 200 is smaller. Therefore, less heat is generated. Therefore, not much lubricating oil is required to absorb the heat. At this time, if the amount of lubricating oil filled is relatively large, it will cause loss and waste.

[0048] In a further embodiment, as Figure 2 and Figure 4 shown, the control assembly 400 includes a pressing ring 410 and a pressure valve 420. The pressing ring 410 is provided on the equipment main body 100, and the pressing ring 410 is located outside the forging punch 200. The pressing ring 410 can move in the vertical direction. The pressing ring 410, the oil storage tank 300, the forging punch 200, and the workpiece 600 can circumferentially enclose 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 provided 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 through the filling port 310 into the first chamber 430.

[0049] In use, the operator first punches a hole at the dial mounting position of the workpiece 600 through a punching device, and then places the workpiece 600 on the forging platform of the device body 100, so that the center of the punched round hole is located on the axis of the forging punch 200. Then, the pressing ring 410 is moved downward in the vertical direction. After the pressing ring 410 presses on the upper surface of the workpiece 600, the pressing ring 410 stops moving downward. Next, the forging punch 200 is moved downward in the vertical direction. As the forging punch 200 continues to move downward, the inverted conical surface of the forging punch 200 gradually expands the punched round hole. When the hole wall of the round hole abuts against the side surface of the forging punch 200, at this time, the pressing ring 410, the oil storage tank 300, the forging punch 200, and the workpiece 600 circumferentially enclose the first chamber 430. At this time, it is the initial state, and the air pressure in the first chamber 430 is the first preset value. The first preset value is one standard atmosphere. 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 one standard atmosphere. 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 part of the 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 atmosphere, 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. During this process, under the action of gravity, the lubricating oil gradually seeps downward through the gap between the forging punch 200 and the workpiece 600, thereby absorbing the heat generated by the forging punch 200 and the workpiece 600 during the forging process, preventing the forging punch 200 and the workpiece 600 from overheating and deforming.

[0050] It can be understood that the thicker the thickness of the workpiece 600, the greater the downward movement distance of the forging punch 200 when the forging punch 200 completes the forging and reaming of the workpiece 600. In this way, the increase in the volume of the first chamber 430 is greater, and the amount of lubricating oil entering the first chamber 430 at this time is more, and the heat can be absorbed to prevent the workpiece 600 and the forging punch 200 from overheating and deforming; on the contrary, the thinner the thickness of the workpiece 600, the smaller the downward movement distance of the forging punch 200 when the forging punch 200 completes the forging and reaming of the workpiece 600. In this way, the increase in the volume of the first chamber 430 is smaller, and the lubricating oil entering the first chamber 430 at this time is less, so that the consumption of the lubricating oil can be reduced and waste can be avoided. In summary, by setting the pressing ring 410, the oil storage tank 300, and the pressure valve 420, the pressing ring 410, the oil storage tank 300, the forging punch 200, and the workpiece 600 circumferentially enclose the first chamber 430, and the increase in the volume 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 reaming on workpieces 600 with different thicknesses, the self-adaptive addition of lubricating oil can be realized, and there is no need to additionally set monitoring components, and the structure is simple and reliable.

[0051] In a further embodiment, as Figure 3 and Figure 4 shown, the fuel tank 300 is slidably connected within the device main body 100, and the fuel tank 300 is fixedly connected to the pressing ring 410.

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

[0053] It should also be added that in order to enable the lubricating oil in the first chamber 430 to be squeezed into the gap between the pressing 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. In this way, 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 pressing ring 410 and the workpiece 600. In addition, in this embodiment, the pressure valve 420 should be a one-way pressure valve 420, and this one-way pressure valve 420 restricts the lubricating oil in the first chamber 430 from flowing into the oil storage chamber. In this way, 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 extruded out through the gap between the pressing ring 410 and the workpiece 600.

[0054] In a further embodiment, as Figure 5 shown, the forging device for the titanium alloy smart watch case further includes a locking assembly 500. The locking assembly 500 is arranged within the device main body 100, and the locking assembly 500 is used to lock and limit the forging punch 200 after the forging punch 200 passes through the bottom of the workpiece 600, restricting the forging punch 200 from moving in the vertical direction.

[0055] It can be understood that when the workpiece 600 is forged and compacted by the pressing ring 410, the frictional force between the workpiece 600 and the forging punch 200 increases. At this time, when the workpiece 600 is forged and compacted, it may drive the forging punch 200 to move downward synchronously by a small distance, which will cause the volume of the first chamber 430 not to decrease. Therefore, after the forging punch 200 passes through the bottom of the workpiece 600, the forging punch 200 needs to be locked and limited by the locking assembly 500 to limit the movement of the forging punch 200 in the vertical direction.

[0056] In a further embodiment, as Figures 4-6 shown, the locking assembly 500 includes a plurality of locking plates 510. 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 further includes a plurality of first hydraulic rods. The plurality of first hydraulic rods correspond to the plurality of locking plates 510 one by one. 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. The fixed end of the first hydraulic rod is arranged on the equipment main body 100.

[0057] In the initial state, there is a preset distance between the locking plate 510 and 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 activated, and the telescopic end of the first hydraulic rod drives the locking plate 510 to approach each other along the radial direction of the forging punch 200. After the locking 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 locking plate 510 and cannot move. After the workpiece 600 is forged and compacted by the pressing ring 410, first, the telescopic end of the first hydraulic rod drives the locking plate 510 to move away from each other along the radial direction of the forging punch 200, so that the locking plate 510 returns to the initial position. Then, the forging punch 200 is moved upward in the vertical direction. Finally, the pressing ring 410 drives the oil storage tank 300 to move upward synchronously, so that the pressing ring 410 and the oil storage tank 300 return to the initial position. At this time, the workpiece 600 can be removed from the equipment main body 100.

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

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

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

[0061] When it is necessary to move the forging punch 200 in the vertical direction, the third hydraulic rod is started, and the pressing ring 410 is driven to move through the telescopic end of the third hydraulic rod. In addition, a cylinder or other linear driving mechanism can also be used to replace the third hydraulic rod to drive the pressing ring 410 to move in the vertical direction.

[0062] In a further embodiment, a liquid filling port is also provided outside the device main body 100. The liquid filling port is communicated with the oil storage tank 300 for replenishing lubricating oil into the oil storage tank 300.

[0063] A forging process for a titanium alloy smart watch case uses the above-mentioned forging device for a titanium alloy smart watch case, and specifically includes the following steps:

[0064] S1: Place the workpiece so that the center of the pre-punched round hole of the workpiece is located on the axis of the forging punch.

[0065] S2: Make the lower part of the side surface of the forging punch pass through the round hole.

[0066] S3: Limit the forging punch through the locking component to restrict the forging punch from moving in the vertical direction.

[0067] S4: Make the pressing ring and the oil storage tank move downward synchronously to forge and compact the workpiece.

[0069] S6: Make the forging punch move upward to reset.

[0070] S7: Make the pressing ring and the oil storage tank move upward to reset.

[0071] S8: Remove the workpiece from the device main body.

[0072] S9: Loop through S1 - S8.

[0073] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0074] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
