DETAILED DESCRIPTION

[0036] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0037] Corresponding levels of display devices are developed for different levels of the market. Mid-to-high-end display devices have a three-dimensional shape and a high metallic texture. The front shell of the display device is generally formed by bending the workpiece in one piece using a bending device.

[0038] In the related art, the workpiece is bent integrally by a bending device to form a bent section of the front shell. When the workpiece is bent, the outer edge of the rounded corner of the front shell is subjected to tensile stress, and the inner edge is subjected to compressive stress, resulting in a larger radius of the rounded corner of the front shell, which limits the narrow and thin design of the display device, and the front shell has a lower degree of protection for the corners of the panel.

[0039] Figure 1 It is a partial structural diagram of a component 1 used for a shaping device 2 according to an embodiment of the present invention. Figure 2 1 is a diagram of the original state of the workpiece 1 used for the shaping device 2 according to an embodiment of the present invention. Figure 3 1 is a diagram showing the shaping state of a workpiece 1 used in a shaping device 2 according to an embodiment of the present invention. Figure 4 It is a three-dimensional diagram of the shaping device 2 according to an embodiment of the present invention.

[0040] See Figures 1 to 4 As shown, the component 1 is an integral continuous structure consisting of two straight plates 11, rounded corners 12, and a flat plate 13. The two straight plates 11 and the rounded corners 12 are formed by bending the edges of the flat plate 13 forward. The component 1 provides strong protection for the corners of other components and facilitates the narrow and thin design of the display device.

[0041] Straight plates 11 are flat, and the two straight plates 11 respectively connect to the left and right edges of flat plate 13. Rounded corners 12 have an arc-shaped cross section, and their sides smoothly connect to the two straight plates 11. The ends of the arc in the cross section of rounded corners 12 correspond to the positions of the two sides of rounded corners 12, that is, the ends of the arc respectively connect to the two straight plates 11. Specifically, the two straight plates 11 are perpendicular to each other, but this is not a limitation.

[0042] The present invention provides a shaping device 2, which is primarily used to shape the rounded corner 12 of a workpiece 1. The shaping device 2 drives two straight plates 11 toward the rounded corner 12 to reduce the rounded corner 12 of the workpiece 1. The inner walls of the two straight plates 11 are subjected to tensile stress that converges at the rounded corner 12. This tensile stress drives the material on the two straight plates 11 to flow toward the rounded corner 12, thereby reducing the radius of the rounded corner 12. This improves the protection provided by the workpiece 1 to the corners of other components and facilitates the narrower and thinner design of display devices.

[0043] Figure 5 It is an exploded view of the shaping device 2 according to an embodiment of the present invention. Figure 9 2 is a structural diagram of the support unit 21 in the shaping device 2 according to an embodiment of the present invention.

[0044] Combine Figure 5 and Figure 9As shown, the shaping device 2 mainly includes a supporting unit 21, two pressing units 22, an extrusion unit 23 and two resetting units 24. The two pressing units 22 are respectively installed on the supporting unit 21 and press the two straight plates 11. The two pressing units 22 move toward the rounded corner 12 of the workpiece 1 under the drive of the extrusion unit 23, so that the inner walls of the two straight plates 11 pressed by the pressing units 22 are subjected to tensile stress converging at the rounded corner 12, thereby reducing the radius of the rounded corner 12.

[0045] The supporting unit 21 includes a platform 211 and a plurality of legs 212 connected to the platform 211 . The plurality of legs 212 are supported on the platform 211 .

[0046] The upper surface of the platform 211 is provided with two first rails 2111, a second rail 2112, and a plurality of avoidance holes 2113. The two first rails 2111 are angled with each other, which can be a right angle to correspond to the arrangement of the two pressing units 22. The two first rails 2111 are spaced apart from the second rail 2112. The second rail 2112 is arranged corresponding to the extrusion unit 23. The first rail 2111 is provided with a first rail groove, and the second rail 2112 is provided with a second rail groove.

[0047] A plurality of avoidance holes 2113 are correspondingly provided on each first track 2111, and the avoidance holes 2113 are used to prevent the two pressing units 22 from interfering with the platform 211 during movement. Specifically, the avoidance holes 2113 are long through holes.

[0048] Figure 6 1 is a top view of the shaping device 2 according to an embodiment of the present invention. Figure 7 It is along Figure 6 A-direction sectional view. Figure 8 yes Figure 7 A local enlarged view of point B.

[0049] See Figures 6 to 8 As shown, the two pressing units 22 are respectively mounted on corresponding first rails 2111 and correspond one-to-one with the two first rails 2111. The pressing unit 22 includes a slide 221, a lifting assembly 222, and a pressing seat 223. The lifting assembly 222 has multiple components. The multiple lifting assemblies 222 are mounted on the slide 221, connected to and driving the pressing seat 223 to press or release the slide 221, thereby causing the pressing seat 223 to press or release the straight plate 11 of the workpiece 1.

[0050] The slide 221 includes a sliding portion 2211 and a positioning portion 2212 . The positioning portion 2212 is mounted on the sliding portion 2211 and moves along with the movement of the sliding portion 2211 .

[0051] The sliding portion 2211 is movably mounted on the first rail 2111 and is capable of moving along the length direction of the first rail 2111 .

[0052] The sliding portion 2211 may optionally be rectangular. Grooves 2211a are provided on both sides of the sliding portion 2211. Optionally, the lower sidewalls of the grooves 2211a are located below the upper surface of the platform 211. The platform 211 is further provided with multiple sets of baffles 2114, each set of baffles 2114 corresponding to the first track groove and mounted on the platform 211 of the support unit 21.

[0053] A set of two baffles 2114 can be optionally provided, and the two baffles 2114 are arranged on both sides of the first track groove and abut against the lower side wall of the groove 2211a to prevent the sliding part 2211 from tilting during movement, thereby improving the stability of the sliding part 2211 and further improving the stability of the slide 2211.

[0054] The positioning portion 2212 is provided with a through positioning groove 2212a, which is arranged according to the outer contour of the straight plate 11 to position the straight plate 11. Optionally, the inner wall of the positioning groove 2212a is in contact with the inner wall of the straight plate 11.

[0055] In the two pressing units 22, the two positioning parts 2212 of the two pressing units 22 are provided with a gap 22a corresponding to the accommodating fillet 12 at the intersection of the moving direction. The gap 22a is connected to each positioning groove 2212a, and the gap 22a provides a shaping space for the fillet 12, thereby improving the smoothness of the shaping of the fillet 12.

[0056] Among them, the sliding part 2211 moves along the length direction of the first rail 2111, and the positioning part 2212 moves with the movement of the sliding part 2211. When the two positioning parts 2212 are in contact with each other, the end at which the two positioning parts 2212 are in contact is the contact end of the positioning part 2212. The end faces of the contact ends of the positioning parts 2212 of the two slides 221 are parallel and parallel to the bisector of the angle between the two first rails 2111, so that the two positioning parts 2212 can simultaneously generate tensile stress on the inner walls of the two straight plates 11, and the direction of the tensile stress converges on the rounded corner 12.

[0057] Figure 10 It is a structural diagram of the pressing unit 22 in the shaping device 2 according to an embodiment of the present invention. Figure 11 Schematic diagram of the pressing unit 22 pressing the straight plate 11 in the shaping device 2 according to an embodiment of the present invention. Figure 12 It is a schematic diagram of the release of the straight plate 11 by the pressing unit 22 in the shaping device 2 according to an embodiment of the present invention.

[0058] Combine Figures 10 to 12As shown, the pressure seat 223 corresponds to the positioning portion 2212 one-to-one, is spaced apart from the positioning portion 2212, and can be pressed or moved away from the positioning portion 2212 in the height direction to achieve the pressure seat 223 pressing or releasing the workpiece 1. The pressure seat 223 presses the workpiece 1, so that the workpiece 1 remains stationary with the sliding portion 2211 of the slide 221 when moving along the length direction of the first track 2111, further reducing the radius of the fillet 12 of the workpiece 1.

[0059] When the pressure seat 223 presses the workpiece 1, the lower surface of the pressure seat 223 fits against the surface of the workpiece 1, so that the workpiece 1 is subjected to the extrusion force between the pressure seat 223 and the positioning portion 2212. The pressure seat 223 presses the workpiece 1 so that the surface of the workpiece 1 is subjected to the extrusion force of the pressure seat 223. The workpiece 1 is firmly pressed between the pressure seat 223 and the positioning portion 2212, and can move with the movement of the pressing unit 22, so that the straight plate 12 of the workpiece 1 can only flow along the predetermined direction under the action of the extrusion force, so that the rounded corner 12 of the workpiece 1 is plastically deformed, the sharp corner shape of the workpiece 1 is realized, and wrinkling of the surface of the workpiece 1 during the shaping process is suppressed.

[0060] When the pressing seat 223 releases the product 1 , the space between the pressing seat 223 and the positioning portion 2212 facilitates the product 1 to separate from the positioning portion 2212 .

[0061] The lifting assembly 222 corresponds to the slide 221 one by one and is installed on the slide 221 . The lifting assembly 222 is connected to and drives the pressing seat 223 to press or release the positioning portion 2212 of the slide 221 , thereby causing the pressing seat 223 to press or release the workpiece 1 .

[0062] The lifting assembly 222 includes a fixed base 2221 and a cylinder 2222 . The cylinder 2222 is mounted on the fixed base 2221 . The fixed base 2221 is fixed on the sliding portion 2211 and moves with the movement of the sliding portion 2211 .

[0063] The output shaft of the cylinder 2222 passes through the platform 211 and the fixed seat 2221 of the support unit 21, connecting and driving the pressing seat 223 to move upward and downward, thereby pressing the pressing seat 223 into or out of the positioning portion 2212 of the slide 221. The output shaft of the cylinder 2222 is disposed in the avoidance hole 2113, which prevents the cylinder 2222 from interfering with the platform 211 during movement.

[0064] Optionally, there are multiple cylinders 2222, and the output shafts of the multiple cylinders 2222 act together on the pressure seat 223. The cylinders 2222 and the avoidance holes 2113 correspond one to one, and the multiple avoidance holes 2113 are optionally arranged at intervals in the length direction of the slide 221.

[0065] The lifting assembly 222 also includes a plurality of guide rods 2223, the axes of which are parallel to the axis of the output shaft of the cylinder 2222. The guide rods 2223 are fixed to the sliding portion 2211 and pass through the pressure seat 223, allowing the pressure seat 223 to rise and fall under the guidance of the guide rods 2223. The guide rods 2223 improve the smoothness and stability of the lifting of the pressure seat 223.

[0066] Optionally, each guide rod 2223 is distributed on two adjacent cylinders 2222 , thereby further improving the smoothness and stability of the lifting and lowering of the pressure seat 223 .

[0067] Figure 13 It is a structural diagram of the extrusion unit 23 in the shaping device 2 according to an embodiment of the present invention. Figure 14 It is a partial connection diagram of the extrusion unit 23 and the pressing unit 22 in the shaping device 2 according to an embodiment of the present invention.

[0068] See Figures 13 and 14 As shown, the extrusion unit 23 includes a driving member 231, a support 232, two push rods 233 and a limit seat 236. The extrusion unit 23 is linked with the two pressing units 22 to drive the two pressing units 22 to squeeze toward the rounded corner 12 at the same time, thereby reducing the rounded corner 12 of the workpiece 1.

[0069] Specifically, the radius of the fillet 12 of the workpiece 1 changes from R≥5mm to R≤1mm. Since the extrusion unit 23 and the pressing unit 22 both apply force to the straight plate 11 of the workpiece 1, the material of the extrusion unit 23 and the pressing unit 22 can be selected from modulated 45# steel, which is not limited here.

[0070] The driving member 231 is mounted on the platform 211 and serves as the power source of the extrusion unit 23. The driving member 231 can be a pneumatic cylinder or a hydraulic cylinder. The axis of the output shaft of the driving member 231 is parallel to the midline of the angle.

[0071] The driving member 231 is connected to and drives the support 232 to move linearly, and the support 232 is movably mounted on the second track 2112 , so that the movement smoothness of the support 232 is improved through the second track 2112 .

[0072] Optionally, the support 232 is further provided with a limit seat 236, which is mounted on the platform 211 of the support unit 21 and located at one end of the second track 2112. A limit plate 2361 is protruded from one side of the limit seat 236. The limit plate 2361 is spaced apart from the platform 211 of the support unit 21 and abuts against the upper end of the support 232, thereby preventing the support 232 from tilting during movement and further improving the movement stability of the support 232.

[0073] One end of each push rod 233 is hinged to the support 232, and the other end is hinged to the platform 211 of the support unit 21, and abuts against the end of the sliding part 2211 of the slide 221. Specifically, a first rotating shaft 234 is movably connected between the push rod 233 and the support 232, and a second rotating shaft 235 is provided between the push rod 233 and the sliding part 2211. The push rod 233 is swung around the second rotating shaft 235 by moving the support 232.

[0074] The two push rods 233 are symmetrically arranged along the axis of the output shaft of the driving member 231 , so that the driving member 231 can drive the two push rods 233 at the same time and improve the linkage performance of the two push rods 233 .

[0075] An arc portion 2331 is provided at one end of the push rod 233 that abuts against the sliding portion 2211 of the slide 221 . The arc portion 2331 facilitates the abutment between the push rod 233 and the sliding portion 2211 .

[0076] The center of the arc portion 2331 is offset from the axis of the second rotating shaft 235, so that there is a gap between the center of the arc portion 2331 and the rotation axis of the push rod 233 relative to the platform 211, thereby realizing the swing of the arc portion 2331 relative to the sliding portion 2211, so as to realize the movement of the sliding portion 2211 along the first track 2111.

[0077] The driving member 231 drives the support 232 to move along the second track 2112, and at the same time drives the two push rods 233 to swing at one end abutting against the slide 221. The swing of the arc portion 2331 of the push rod 233 relative to the sliding portion 2211 of the slide 221 causes the opposite ends of the positioning portions 2212 of the two slides 221 to approach or move away from each other.

[0078] When the output shaft of the driving member 231 is in the extended state, the arc portions 2331 of the two push rods 233 swing relative to the sliding portion 2211, so that the two sliding portions 2211 are squeezed in the direction toward the rounded corner 12. At this time, the workpiece 1 is in a pressed state, and the opposite ends of the two positioning portions 2212 approach each other, and drive the two straight plates 11 to squeeze toward the rounded corner 12 to reduce the rounded corner 12 of the workpiece 1.

[0079] After the rounded corner 12 of the workpiece 1 is shaped, the lifting assembly 222 drives the pressing seat 223 to move away from the positioning portion 2212 in the height direction, so that the pressing seat 223 releases the workpiece 1, thereby facilitating the workpiece 1 to be separated from the positioning portion 2212.

[0080] When the pressure seat 223 is completely away from the positioning portion 2212, the output shaft of the driving member 231 can begin to reset. At this time, the arc portions 2331 of the two push rods 233 swing relative to the sliding portion 2211, so that the two sliding portions 2211 move in the direction away from the fillet 12, and the opposite ends of the two positioning portions 2212 move away from each other.

[0081] There are two reset units 24, one corresponding to each of the two pressing units 22. The reset units 24 are mounted on the platform 211 of the support unit 21 and are elastically connected to the sliding portion 2211 of the slide 221. This allows the sliding portion 2211 to reset under the action of an elastic force, thereby resetting the pressing units 22 and maintaining the gap 22a between the two pressing units 22 in the initial state. The elastic force exerted by the reset units 24 on the sliding portion 2211 can reset the pressing units 22 to their initial position after the shaping action, allowing for the next shaping action to be performed, thereby achieving a cyclic operation.

[0082] Figure 6 1 is a top view of the shaping device 2 according to an embodiment of the present invention. Figure 7 It is along Figure 6 A-direction sectional view.

[0083] See Figure 6 and Figure 7 As shown, the reset unit 24 includes a mounting seat 241 , a pull rod 242 and an elastic member 243 .

[0084] The mounting seat 241 is on the platform 211 of the support unit 21, and the mounting seat 241 can be fixed on the platform 211 by screws. The pull rod 242 is movably provided on the mounting seat 241, and the end of the pull rod 242 is fixedly connected to the sliding part 2211 of the slide 221.

[0085] Optionally, the sliding portion 2211 is provided with a boss 2211b, which is located on an end of the sliding portion 2211 away from the rounded corner 12. The boss 2211b is fixedly connected to the end of the pull rod 242.

[0086] An elastic member 243, which can be a tension spring, is sleeved around the outer periphery of the pull rod 242. One end of the elastic member 243 is connected to the mounting seat 241, and the other end is connected to the head of the pull rod 242. This allows the pull rod 242 to drive the sliding portion 2211 to return to its original position when the pressing seat 223 is disengaged from the positioning portion 2212 of the slide 221, thereby maintaining the gap 22a between the two pressing units 22 in the initial state.

[0087] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0088] In the shaping device 2 of the embodiment of the present invention, the pressing unit 22 includes a slide 221, a lifting assembly 222 and a pressure seat 223. The slide 221 can move along the length direction of the first track 2111. The slide 221 is provided with a positioning groove 2212a for positioning the straight plate 11. The lifting assembly 222 is installed on the slide 221, connected to and drives the pressure seat 223 to press or disengage from the slide 221, so that the pressure seat 223 presses or releases the workpiece 1. The pressure seat 223 presses the workpiece 1 so that the surface of the workpiece 1 is subjected to the pressure of the pressure seat 223. The workpiece 1 is firmly pressed between the pressure seat 223 and the slide 221, and wrinkles on the surface of the workpiece 1 during the shaping process are suppressed. When the pressure seat 223 releases the workpiece 1, the workpiece 1 can be easily separated from the slide 221.

[0089] In addition, the driving member 231 connects and drives the support 232 to move linearly, and drives the end of each push rod 233 in contact with the slide 221 to swing, so that the opposite ends of the two slides 221 approach each other, and drive the two straight plates 11 to be squeezed toward the rounded corner 12 to reduce the rounded corner 12 of the component 1, wherein the inner walls of the two straight plates 11 correspondingly pressed by the two pressing units 22 are subjected to tensile stress squeezed at the rounded corner 12, and the tensile stress drives the materials of the two straight plates 11 to flow convergently onto the rounded corner 12, so that the radius of the rounded corner 12 is reduced, thereby improving the protection of the component 1 to the corners of other components and facilitating the narrow and thin design of the display device.

[0090] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
