Description

Technical Field

[0001] The invention relates to the technical field of lamp processing, and in particular to a stamping device for processing a lamp shell. Background Art

[0002] A lamp is an appliance that can transmit light, distribute and change the light distribution of a light source. It includes all parts required to fix and protect the light source except the light source, as well as the circuit accessories necessary for connecting to the power supply. In the production process of lamps, stamping devices are often used to stamp the lamp housing. A stamping machine, also known as a stamping press, is a type of equipment for forming metal or non-metallic materials. In industrial production, the stamping process has the advantages of saving materials and energy, high efficiency, and low requirements on operators compared to traditional mechanical processing. Through the application of various molds, products that cannot be achieved by mechanical processing can be made. In addition, stamping production can make blanking, punching, forming, shaping, riveting and extrusions through molds, so stamping machines are widely used in various fields.

[0003] Patent No. CN117548548A discloses a stamping device for rapid prototyping lamps, including a work frame, a bearing platform slidably connected to the work frame, a stamping block for stamping operations mounted on the bearing platform, a stamping slot provided on the work frame, a servo cylinder for driving the bearing platform to slide vertically, so that the stamping block abuts against the stamping slot; a lifting mechanism is provided inside the work frame, the lifting mechanism includes a lifting plate vertically slidably connected, and the lifting plate is connected to the bearing platform through a transmission assembly. The lifting plate is driven to slide upward by the transmission assembly, and the lifting plate drives the lamp workpiece located inside the stamping slot to slide upward, and the workpiece is taken out of the stamping slot. This method uses the servo cylinder to drive the bearing platform to recover the work position to take out the workpiece, so there is no need to use an additional driving mechanism to take out the workpiece, which can not only improve work efficiency.

[0004] During the sheet metal stamping work of the metal lamp housing, it is necessary to use mold red lead to brush on the mold core and the mold core, and the accuracy is judged by observing the distribution of red lead during the stamping process. However, the above-mentioned equipment has the problem that the mold core and the mold core are prone to uneven friction on the sheet metal surface when stamping the sheet metal, which can easily cause the finished part to deform inside the mold core beyond the tolerance. Secondly, the mold core is prone to excessive wear after long-term work, which will reduce the qualified rate of the final finished parts. At the same time, it is not convenient for users to observe the distribution of red lead inside the mold core during the debugging stage.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The invention provides a stamping device for processing a lamp housing.

[0049] First embodiment:

[0050] Please combine Figures 1 to 9 , a stamping device for processing a lamp housing, comprising a frame 1, an upper die 3, a driving mechanism 4, a sheet metal blank 12 and a lamp housing finished part 16;

[0051] The outer wall of the frame 1 is fixedly provided with a placement plate 9, the upper surface of the placement plate 9 is installed with a lower mold 2, a mold core 15 is embedded inside the lower mold 2, a stabilizing mechanism 5 is installed at the middle position inside the lower mold 2, and four limiting mechanisms 6 are installed inside the mold core 15;

[0052] The driving mechanism 4 includes a motor 41 installed on the side of the frame 1, the output shaft keyway of the motor 41 is connected to a driving rod 42, the output end keyway of the driving rod 42 is connected to a driving pulley 43, the side of the frame 1 and away from the motor 41 is rotatably connected to a driven pulley 44, the driving pulley 43 and the driven pulley 44 are sleeved with a driving belt 45, the axis of the driven pulley 44 is keyed to an extension rod 46, the two sides of the frame 1 are rotatably connected to a crankshaft 47, the outer wall of the crankshaft 47 is sleeved with a lifting rod 48, and the bottom of the upper mold 3 is installed with a mold core 14;

[0053] See also Figure 3 : Starting the motor 41 can drive the driving rod 42 to rotate clockwise. The clockwise rotating driving rod 42 can control the driving pulley 43 to drive the driven pulley 44 at the bottom to rotate clockwise through the driving belt 45. The clockwise rotating driven pulley 44 can control the crankshaft 47 to rotate from top to bottom. The rotating crankshaft 47 will drive the lifting rod 48 to control the linkage control of the upper mold 3 to descend along the vertical direction of the frame 1 and close the lower mold 2.

[0054] The bottom end of the lifting rod 48 is rotatably connected to the top of the upper mold 3, the crankshaft 47 is key-connected to the axis of the driven pulley 44, and the frame 1 is slidably connected to the upper mold 3 by a vertical slide rod.

[0055] Combination Figure 3 It can be seen and understood that: since the lifting rod 48 will be bent by the rotation of the crankshaft 47, the use of a rotating design can avoid interference between the lifting rod 48 and the upper mold 3. The back of the entire upper mold 3 and the frame 1 are slidably connected, which can ensure the stability of the upper mold 3 when it is lifted or lowered.

[0056] The stabilizing mechanism 5 comprises a fixed tube 51 fixed to the inner bottom of the lower mold 2, the outer wall of the fixed tube 51 is provided with a first through hole 52, the outer wall of the first through hole 52 is connected and fixed with a hose 53, the interior of the fixed tube 51 is slidably connected with a negative pressure tube 54, a return spring 56 is placed inside the fixed tube 51 and below the negative pressure tube 54, a rubber ring 57 is fixed at the top of the negative pressure tube 54, and the interior of the negative pressure tube 54 is provided with a second through hole 55;

[0057] See also Figure 4 : Before the upper mold 3 and the lower mold 2 are closed, the sheet metal blank 12 needs to be located on the surface of the lower mold 2. As the upper mold 3 descends, it will be closed with the lower mold 2, so that the mold core 14 and the mold core 15 will be closed, so that the sheet metal blank 12 can be stamped to finally form a finished product 16 that is exactly the same as the mold core 15.

[0058] See also Figure 5 and Figure 6: When the finished part 16 is in the process of being formed, the pressure from the upper mold 3 will force the sheet metal blank 12 to ensure the molding of the finished part 16. The bottom of the finished part 16 will contact the rubber ring 57 at the top of the negative pressure tube 54. The pressure from the upper mold 3 will drive the finished part 16 to continuously control the negative pressure tube 54 to move downward inside the fixed tube 51. During the movement, the reset spring 56 is compressed. When the second through hole 55 inside the negative pressure tube 54 moves to the position of the first through hole 52 (the outer end of the hose 53 can be connected to peripheral equipment such as a negative pressure pump), the negative pressure suction inside the hose 53 will pass through the first through hole 52 and the second through hole 55 to allow the negative pressure suction to pass through the negative pressure tube 54 to suck the entire finished part 16.

[0059] The apertures of the first through hole 52 and the second through hole 55 are adapted to each other, and the negative pressure tube 54 is slidably connected to the fixed tube 51 .

[0060] It can be understood that since the sheet metal blank 12 is a hard metal material, the metal finished part 16 will not form the shape of the negative pressure tube 54 during the forming process, but will form the shape of the mold core 14, and the bottom of the finished part 16 will squeeze the rubber ring 57 and become deflated, which can greatly improve the suction and sealing of the negative pressure tube 54 on the finished part 16.

[0061] The limiting mechanism 6 includes a limiting plate 64 fixedly arranged inside the lower mold 2, the limiting plate 64 is slidably connected inside with a trigger rod 62, the outer wall of the trigger rod 62 is sleeved with a limiting spring 65, the bottom end of the trigger rod 62 is fixedly provided with a contact rod 63, the mold core 15 is slidably connected inside with a moving rod 66, the moving rod 66 is fixedly provided with an inner spring 67, and the front end of the inner spring 67 is fixedly provided with a limiting rod 61.

[0062] The upper and lower ends of the limit spring 65 are fixedly connected to the trigger rod 62 and the limit plate 64. The bottom slope of the contact rod 63 has an inclination angle of 45 degrees, and the right end slope of the moving rod 66 has an inclination angle of 40 degrees.

[0063] The limiting rod 61 is slidably connected to the moving rod 66 , and the front end of the limiting rod 61 is arc-shaped.

[0064] See also Figure 7 and Figure 8: When the upper mold 3 and the lower mold 2 are successfully closed, the lower surface of the upper mold 3 will be closely fitted with the upper surface of the upper mold 3. During the process of lowering the mold, the upper mold 3 will squeeze the control trigger rod 62 to drive the contact rod 63 to descend. During the process of descending the contact rod 63, the inclined surface of the contact rod 63 will be inclined to the inclined surface of the force-bearing moving rod 66. At this time, the moving rod 66 will be driven by the descent of the contact rod 63 to move the limit rod 61 toward the inside of the mold core 15. Therefore, when the mold core 14 drives the sheet metal blank 12 and the mold core 15 to form a finished part 16, the outer wall of the finished part 16 will move relative to the moving limit rod 61, and the four extended limit rods 61 can limit the finished part 16.

[0065] See also Fig. 9 : It can be understood that since the limit rod 61 can also move elastically inside the movable rod 66, when the finished product 16 is finally fitted with the mold core 15, the limit rod 61 will be forced in the opposite direction into the mold core 15 by the pressure of the mold core 14.

[0066] This embodiment: Compared with the traditional design, this case is designed with a negative pressure tube 54 that can follow the rising and falling movement of the mold core 14. Therefore, the final lamp housing finished product 16 will continue to fit with the top of the negative pressure tube 54, and in the final molding stage, the negative pressure tube 54 will be connected to the hose 53 to form a negative pressure suction force to suck the finished product 16, so that the sheet metal surface around the finished product 16 can be prevented from being able to stably apply force to the pressure of the mold core 14, avoid uneven friction, and effectively reduce the final tolerance of the finished product 16. At the same time, the staggered apertures of the first through hole 52 and the second through hole 55 are different when they descend. In this way, the greater the suction force generated as the depth of descent increases, the more stable the suction force can be further increased. At the same time, four synchronous telescopic limit rods 61 are used to position the four arc points of the finished product 16. This design can avoid the situation where the finished product 16 is offset during molding, eliminates the side tolerance, and is also convenient for users to observe the distribution of red lead in the internal mold, effectively improving the qualified rate of the finished product 16.

[0067] Second embodiment:

[0068] See also Figures 10 to 12 A pusher assembly 7 is installed on the outside of the upper mold 3, and the pusher assembly 7 includes a mounting seat 71 fixed to the side wall of the upper mold 3, the interior of the mounting seat 71 is rotatably connected to a first inclined plate 72 via a coil spring, and the bottom end of the first inclined plate 72 is rotatably connected to a second inclined plate 73 via a coil spring. Equally spaced blanking holes 13 are opened inside the sheet metal blank 12, and a support 11 and a positioning plate 10 are fixed on the upper surface of the placement plate 9 and on both sides of the lower mold 2, respectively.

[0069] See also Fig.10: When batch-producing finished parts 16, the upper mold 3 is in the process of descending and closing with the lower mold 2, and the bottom end of the second inclined plate 73 will obliquely force the inner wall of the blank 12 with the blanking hole 13 (the blanking hole 13 is left on the sheet metal blank 12 after the finished product 16 is produced). As the upper mold 3 descends, the first inclined plate 72 will continue to push the sheet metal blank 12 to the right, so that the unprocessed part of the sheet metal blank 12 can be moved to the processing position.

[0070] See also Fig.11 : After the upper mold 3 and the lower mold 2 are successfully closed, the upper mold 3 and the lower mold 2 will position and lock the sheet metal blank 12. Since the oblique movement force of the second inclined plate 73 will be smaller than the locking force of the sheet metal blank 12, the middle position of the first inclined plate 72 and the second inclined plate 73 will bend, and finally the second inclined plate 73 and the previous blanking hole 13 will be separated.

[0071] See also Fig.12 : After the final stamping work is completed, the upper die 3 is reset to the initial state, the first inclined plate 72 and the second inclined plate 73 start to reset to the initial state, and the second inclined plate 73 will return to the inside of the blanking hole 13 on the left.

[0072] The bottom end of the second inclined plate 73 is in an arc structure, and the bottom end of the second inclined plate 73 contacts the inner wall of the blanking hole 13 . The sheet metal blank 12 is slidably connected with the support 11 and the positioning plate 10 .

[0073] It can be understood that the positioning plate 10 and the support 11 are used to limit the sheet metal blank 12, so that the sheet metal blank 12 can be prevented from warping and deflecting during movement, and when Fig.10 Status switched to Fig.11 In the state, the moving force of the second inclined plate 73 will be smaller than the friction force of the positioning plate 10 and the support platform 11 on the sheet metal blank 12, so the sheet metal blank 12 will not be displaced unnecessarily.

[0074] This embodiment of the present invention: When working in batches, the upper mold 3 can drive the second inclined plate 73 to push the blanking holes 13 on the sheet metal blank 12 after production during the descending process, so that the sheet metal blank 12 can be automatically pushed before the mold is closed. Therefore, this pushing method is formed according to the blanking holes 13 generated when the previous finished part 16 is produced. Therefore, this pushing method has a simple structure and does not require additional drive, which saves costs and ensures that the spacing between each blanking hole 13 is the same, which also saves production materials and avoids waste of sheet metal blanks 12.

[0075] Third embodiment:

[0076] See also Figure 3 , Fig.13 and Fig.14, also includes a material picking mechanism 8, which includes a mounting frame 82, a first column 85 and a second column 86, the front end keyway of the extension rod 46 is connected to the first gear 81, the outer wall of the mounting frame 82 is fixedly provided with a double-layer plate 811, the interior of the mounting frame 82 is rotatably connected with a rotating rod 83, the top of the rotating rod 83 is fixedly provided with a second gear 84, the top of the first column 85 is rotatably connected with a double-groove pulley 87, the top of the second column 86 is rotatably connected with a first pulley 88, the interior of the double-layer plate 811 is rotatably connected with a second pulley 812, the first pulley 88, the second pulley 812 and the double-groove pulley 87 are respectively sleeved with a first belt 89 and a second belt 813, the bottom end of the rotating rod 83 is fixedly provided with a ratchet 815, the outer wall of the ratchet 815 is sleeved with a ratchet sleeve 814, and the top of the first pulley 88 is fixedly provided with a material picking clamp 810.

[0077] See also Figure 3 and Fig.13 : When the mold is closed, the driven pulley 44 rotates clockwise, so the clockwise rotating driven pulley 44 will drive the first gear 81 to rotate clockwise through the extension rod 46, and the clockwise rotating first gear 81 will mesh with the second gear 84 to rotate clockwise. Since the second gear 84 will drive the rotating rod 83 to control the rotating rod 83 to make the ratchet 815 rotate clockwise, the clockwise rotating ratchet 815 will not affect the ratchet sleeve 814;

[0078] See also Figure 3 , Fig.13 and Fig.14 : After the first embodiment is completed, the upper mold 3 and the lower mold 2 need to be separated. During the separation, the driven pulley 44 will drive the first gear 81 to engage and control the second gear 84 to rotate counterclockwise. The second gear 84 drives the rotating rod 83 to control the ratchet 815 to rotate counterclockwise, and drives the ratchet sleeve 814 to rotate counterclockwise to control the second pulley 812. Through the second belt 813, the double-groove pulley 87 rotates counterclockwise. The double-groove pulley 87 transmits the first belt 89 to make the first pulley 88 control the material picking clamp 810 to rotate 360 ​​degrees to take out the finished product 16.

[0079] The first column 85 and the second column 86 are fixedly connected to the placement plate 9 , the first gear 81 and the second gear 84 are meshed with each other, and the axis of the ratchet sleeve 814 is fixedly connected to the axis of the second pulley 812 .

[0080] See also Fig.13 Since the material taking clamp 810 is in a semicircular arc shape and the surface of the finished part 16 is a step-shaped structure, the material taking clamp 810 can clamp the finished part 16 to prevent it from falling;

[0081] And from Figure 3As can be seen from the figure, the diameters of the driving pulley 43 and the driven pulley 44 are different. Since the diameters of the first gear 81 and the driven pulley 44 are different, the rotation speed of the first gear 81 is definitely faster than that of the driven pulley 44. Therefore, when the finished part 16 is extended, the material taking clamp 810 rotates to the position of the finished part 16 at a faster speed. When the upper mold 3 returns to the initial position, the material taking clamp 810 drives the taken-out finished part 16 to the initial position. (In actual use, if the rotation of the material taking clamp 810 and the reset of the upper mold 3 interfere with each other, the user can adjust the differential ratio between the first gear 81 and the driven pulley 44 according to the actual situation).

[0082] In this embodiment, an independent material picking mechanism 8 is provided, and the material picking mechanism 8 does not need to be provided with an additional drive. After the working mold separation is completed, the negative pressure tube 54 ejects the finished part 16, and when the driven pulley 44 and the state during the mold closing are in the opposite direction, the material picking clamp 810 can be started to first pick up the ejected finished part 16. Such a design structure is simple and saves manufacturing costs, and the differential ratio can be used to achieve accurate material picking. At the same time, compared with the traditional direct ejection or hydraulic clamping method, this material picking method not only saves costs, but also avoids workers from manually picking up materials. Workers only need to pick up materials from the outside of the frame 1, further improving the overall safety of the equipment.

[0083] Please refer to Figures 1 to 14 The present invention provides a method for using a stamping device for lamp housing processing as follows:

[0084] Step S1: Starting the motor 41 can drive the driving rod 42 to rotate clockwise. The driving rod 42 rotating clockwise can control the driving pulley 43 to drive the driven pulley 44 at the bottom to rotate clockwise through the driving belt 45. The driven pulley 44 rotating clockwise can control the crankshaft 47 to rotate from top to bottom. The rotating crankshaft 47 will drive the lifting rod 48 to control the linkage control of the upper mold 3 to descend along the vertical direction of the frame 1 and to close the mold with the lower mold 2. Before the upper mold 3 and the lower mold 2 are closed, the sheet metal blank 12 needs to be located on the surface of the lower mold 2. Since the upper mold 3 will be closed with the lower mold 2 when it descends, the mold core 14 and the mold core 15 will be closed, so that the sheet metal blank 12 can be stamped and finally formed with the mold core 15 is exactly the same as the finished product 16. When the finished product 16 is in the process of being formed, the pressure from the upper mold 3 will force the sheet metal blank 12 to ensure the molding of the finished product 16. The bottom of the finished product 16 will contact the rubber ring 57 at the top of the negative pressure tube 54. The pressure from the upper mold 3 will drive the finished product 16 to continuously control the negative pressure tube 54 to move downward inside the fixed tube 51. During the movement, the reset spring 56 is compressed. When the second through hole 55 inside the negative pressure tube 54 moves to the position of the first through hole 52 (the outer end of the hose 53 can be connected to peripheral equipment such as a negative pressure pump), the negative pressure suction inside the hose 53 will pass through the first through hole 52 and the second through hole 55 to allow the negative pressure suction to pass through the negative pressure tube 54 to suck the entire finished product 16.

[0085] Step S2: When the mold is lowered to close, the upper mold 3 will squeeze the control trigger rod 62 to drive the contact rod 63 to descend. When the contact rod 63 descends, the inclined surface of the contact rod 63 will be inclined to the inclined surface of the force-bearing moving rod 66. At this time, the moving rod 66 will be driven by the descent of the contact rod 63 to move the limit rod 61 toward the inside of the mold core 15. Therefore, when the mold core 14 drives the sheet metal blank 12 and the mold core 15 to form the finished part 16, the outer wall of the finished part 16 will move relative to the moving limit rod 61, and the four extended limit rods 61 can limit the finished part 16.

[0086] Step S3: When batch-producing finished parts 16, the upper mold 3 is in the process of descending and closing with the lower mold 2, and the bottom end of the second inclined plate 73 will obliquely force the inner wall of the blanking hole 13 on the sheet metal blank 12 (the blanking hole 13 is left on the sheet metal blank 12 after the finished product 16 is produced). As the upper mold 3 descends, the first inclined plate 72 will continue to push the sheet metal blank 12 to the right, so that the unprocessed part of the sheet metal blank 12 can be moved to the processing position.

[0087] Step S4: the upper mold 3 and the lower mold 2 are separated. When separating the molds, the driven pulley 44 will drive the first gear 81 to mesh and control the second gear 84 to rotate counterclockwise. The second gear 84 drives the rotating rod 83 to control the ratchet 815 to rotate counterclockwise and drive the ratchet sleeve 814 to rotate counterclockwise to control the second pulley 812 to rotate counterclockwise through the second belt 813, and the double-groove pulley 87 rotates counterclockwise. The double-groove pulley 87 transmits the first belt 89 to make the first pulley 88 control the material removal clamp 810 to rotate 360 ​​degrees to take out the finished product 16.

[0088] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
