Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamp processing, and in particular to a lamp plate processing die. BACKGROUND

[0002] In the current lamp plate processing field, the design and application of the die play a key role in production efficiency. Most of the traditional lamp plate processing dies adopt a single engineering die form, which will lead to the need for two or even three sets of dies to work together for lamp plate processing. The most prominent disadvantage is low production efficiency. Frequent die replacement not only consumes a lot of manpower and time cost for die loading and unloading and debugging, but also easily introduces subtle processing errors after each die replacement, repositioning, and calibration, which cumulatively adversely affects the final production quality of the lamp plate and is difficult to meet the current demand for rapid delivery and large-scale production.

[0054] Various exemplary embodiments, features, and aspects of the present disclosure will be explained in greater detail below with reference to the accompanying drawings. Like reference numerals may be used to refer to like elements throughout. While various aspects of embodiments are illustrated, the embodiments need not be used to scale unless specifically indicated.

[0055] The term "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0056] In addition, for the purpose of convenience and brevity, detailed descriptions of well-known functions and structures incorporated in the disclosure will be omitted. It will be appreciated that the disclosure can be practiced with the elements and devices not precisely as illustrated and described.

[0057] An embodiment of the present application provides a lamp panel processing die, comprising an upper die seat 10 and a lower die seat 20 movably coupled in a vertical direction;

[0058] A stretching mechanism, a punching mechanism, and a bending mechanism are sequentially arranged between the upper die seat 10 and the lower die seat 20, and a feeding mechanism 400 is arranged on one side of the upper die seat 10 and the lower die seat 20;

[0059] The stretching mechanism, the punching mechanism, and the bending mechanism respectively perform stretching forming, side punching, and bending forming on a test mold material of the lamp panel when the upper die seat 10 and the lower die seat 20 are closed, and feeding between the stretching mechanism, the punching mechanism, and the bending mechanism is completed by the feeding mechanism 400 in an open mold state.

[0060] In the embodiment, a lamp disc processing die integrating stretching, punching and bending is provided. Specifically, the test die material is sent into the stretching mechanism by the feeding mechanism 400, and the stretching mechanism can stretch the test die material into a target shape when the upper and lower die seats are closed. Then, the feeding mechanism 400 can send the stretched test die material into the punching mechanism in the open die state, and the test die material is punched on the side wall by the punching mechanism when the upper and lower die seats are closed. Finally, the feeding mechanism 400 sends the test die material punched on the side wall into the bending mechanism, and the finished product is pushed out of the die by the feeding mechanism 400 after being bent in the closed die state, thereby completing the entire product processing. Compared with the single-engine die, the lamp disc die of the embodiment can continuously and efficiently produce. The conventional single-engine die can only process 6 pieces per minute and 360 pieces per hour, while the die of the embodiment improves the processing efficiency of the entire lamp disc product, with an efficiency of 30 pieces per minute and 1800 pieces per hour. The entire process is continuous and automatic production without manual assistance, which significantly improves the production efficiency.

[0061] In some embodiments, the stretching mechanism includes a first upper clamping plate 110 arranged at the bottom of the upper die seat 10, a first upper guide rod 120 arranged at one end in the upper die seat 10 and at the other end through the first upper clamping plate 110, a first upper stripper plate 130 arranged at the bottom of the first upper guide rod 120, and a stretching concave die 131 arranged in the first upper stripper plate 130, a lower clamping plate 180 arranged at the top of the lower die seat 20, a first lower stripper plate 140 arranged at the top of the lower clamping plate 180, and a stretching convex die 141 arranged in the first lower stripper plate 140 matched with the stretching concave die 131, and a lower guide rod 150 arranged on the lower die seat 20 and extending to the lower clamping plate 180. In the closed die state, the first upper guide rod 120 pushes the first upper stripper plate 130 to move downward, and the lower guide rod 150 pushes the first lower stripper plate 140 to move upward, so that the stretching concave die 131 and the stretching convex die 141 are in contact to stretch the initial test die material into a shape.

[0062] The stretching mechanism of this embodiment comprises, from top to bottom, a first upper clamping plate 110, a first upper stripping plate 130, a first lower stripping plate 140, and a lower clamping plate 180, disposed between the upper die base 10 and the lower die base 20. Furthermore, a first upper guide rod 120 is disposed on the upper die base 10 of this embodiment, the lower end of which passes through the first upper clamping plate 110 and extends to the first upper stripping plate 130. Furthermore, a lower guide rod 150 is disposed on the lower die base 20, the upper end of which extends to the lower clamping plate 180. It should be noted that a stretching die 131 is provided in the first upper release plate 130, which matches the stretching punch 141 provided in the first lower release plate 140, so that when the upper die base 10 and the lower die base 20 are in a closed mold state, the test mold material placed between the first upper release plate 130 and the first lower release plate 140, that is, the initial stamping part of the part to be processed, can be stretched and formed by cooperating with the stretching punch 141 and the stretching die 131, so that the shape of the stretched lamp panel is punched out on the surface of the stamping part.

[0063] Specifically, in the mold opening state, the feeding mechanism 400 feeds the initial mold trial material to the right into the stretching mechanism, such as Figure 1 As shown, the test material A to be stretched is placed between the first upper release plate 130 and the first lower release plate 140. In the closed mold state, during the downward stamping process of the mold, the first upper guide rod 120 can apply pressure to the first upper release plate 130, and the lower guide rod 150 can apply pressure to the first lower release plate 140 through the lower clamping plate 180, so that the first upper release plate 130 and the first lower release plate 140 can simultaneously press the test material. In addition, during the downward stamping process, the stretching punch 141 and the stretching die 131 can also be brought into contact and formed, as shown in FIG. Figure 2 As shown, the initial part to be processed, i.e., the stamped part, is stretched, thereby obtaining a processed lamp panel A' with a stretched shape. The overall structure is tightly coordinated and has a clear division of labor. The first upper clamping plate 110 ensures the stability of the overall stretching action, and the setting of the first upper guide rod 120 can provide reliable guidance for the precise movement of the first upper stripper 130, ensuring the accuracy of its vertical movement and avoiding deviation during the stretching process. At the same time, the mutually coordinated stretching punch 141 and stretching die 131 can ensure that the test mold material is evenly stressed during the stretching process. Compared with the unidirectional pressure stretching method, the bidirectional drive can complete the material stretching in a shorter time.

[0064] In some embodiments, the forming end surface of the stretching punch 141 conforms to the target stretched shape of the initial trial mold material.

[0065] It should be noted that the stretching punch 141 of this embodiment matches the stretching die 131, wherein the forming end face of the stretching punch 141 conforms to the target stretching shape of the initial trial mold material. Here, it should be noted that conforming means the same shape. Figure 9 andFigure 10 As shown, the main body shape of the finished lamp panel of the embodiment is in a trapezoidal convex structure, and the trapezoidal convex structure is provided with a bending structure in the circumferential direction, and the role of the stretching structure is to preliminarily stretch the initial test mold material into the main body of the lamp panel, i.e. the trapezoidal convex structure. Therefore, the upper end surface of the stretching punch 141 of the embodiment, i.e. the forming end surface, is also specifically in a trapezoidal convex structure, which matches the target stretching shape of the test mold material, so that the target stretching shape can be punched out in the mold when downward stamping.

[0066] In some embodiments, the first upper guide rod 120 is provided at the top with a pressure spring 160, which can apply pressure to the first upper stripper plate 130 through the first upper guide rod 120 in the closed mold state.

[0067] It should be noted that the upper die seat 10 of the embodiment is also provided with a pressure spring 160, and the bottom of the pressure spring 160 is in contact with the first upper guide rod 120, which can apply pressure to the first upper stripper plate 130 through the pressure spring 160 during the downward stamping of the mold in the closed mold state, so as to apply pressure to the first upper stripper plate 130, so that the test mold material can be fully stretched.

[0068] In some embodiments, the lower guide rod 150 is provided at the bottom with a nitrogen spring 170, which can apply pressure to the first lower stripper plate 140 through the lower guide rod 150 in the closed mold state.

[0069] It should be noted that the embodiment is also provided with a nitrogen spring 170, and the nitrogen spring 170 can apply pressure to the first lower stripper plate 140 through the lower clamp plate 180 during the downward stamping of the mold in the closed mold state, which cooperates with the pressure spring 160 acting on the first upper stripper plate 130 to press the first upper stripper plate 130 and the first lower stripper plate 140 to the test mold material at the same time, and to make the stretching punch 141 contact the stretching recess 131 for forming by downward stamping, so as to realize the stretching of the test mold material. Under the bidirectional action of the nitrogen spring 170 and the pressure spring 160, the stretching punch 141 and the stretching recess 131 can be uniformly and stably contacted, so as to guarantee the forming quality of the product.

[0070] In some embodiments, the punching mechanism includes: a second upper clamping plate 210, which is arranged at the bottom of the upper die base 10; an upper ejector rod 220, one end of which is arranged in the upper die base 10, and the other end is arranged through the second upper clamping plate 210, and the bottom of the upper ejector rod 220 is provided with a first inclined surface; a de-board fixing insert 230, which is arranged at the bottom of the upper ejector rod 220, and the top is provided with a second inclined surface matching the first inclined surface; wherein, the de-board fixing insert 230 is arranged at the bottom of the upper ejector rod 220, and ... The interior of the fixed insert 230 is provided with an accommodating space; wherein, the accommodating space is provided with a restoring spring 232 and a punching punch 231 perpendicular to the side wall of the test mold material; the lower pad 240 is provided at the bottom of the de-board fixed insert 230, for placing the stretched test mold material; when the mold is closed, the upper push rod 220 pushes the punching punch 231 to pass through the side wall of the stretched test mold material; when the mold is open, the restoring spring 232 uses elastic force to pop the punching punch 231 out of the test mold material with a through hole.

[0071] In this embodiment, after the mold test material is stretched by the stretching mechanism, the feeding mechanism 400 feeds the mold test material to the punching mechanism in the mold opening state. Figure 3 As shown, the test mold material B to be punched is placed on the lower pad 240, which facilitates the use of the punching punch 231 in the punching mechanism to punch the side wall. Specifically, when the upper die base 10 punches downward, the upper push rod 220 moves downward accordingly, and the first inclined surface set at its bottom fits with the punching punch 231 and the upper part of the recovery spring 232, so that it can push the punching punch 231 in the de-board fixed insert 230 toward the stretched test mold material, that is, the position of the stamping part. It should be noted that the punching punch 231 in this embodiment is obliquely inserted into the de-board fixed insert 230 and can move along its oblique setting direction, and the recovery spring 232 is set parallel to the punching punch 231. At the same time, the lower part of the stripping fixed insert 230 is provided with an inclined surface that matches the side wall of the test mold material. When in the closed mold state, the inclined surface of the lower part of the stripping fixed insert 230 is in contact with the side wall of the test mold material, that is, the stamping part. The punching punch 231 in the stripping fixed insert 230 moves toward the stamping part under the push of the upper push rod 220, passes through the stamping part and penetrates the punch under the stamping part, thereby forming a through hole on the side wall of the stamping part. Figure 4 As shown, in the closed mold state, the punching punch 231 punches a hole in the side wall of the stamped part to obtain a trial mold material B' with a through hole in the side wall. Moreover, when the mold is in the open mold state, the punching punch 231 can be ejected from the stamped part by the elastic force of the return spring 232, allowing the stamped part to be freed from the mold. That is, the punching mechanism of this embodiment can punch out the through hole set on the side of the part and the excess material.

[0072] In some embodiments, the accommodation space is further provided with a movable element 233; the movable element 233 is located between the upper top rod 220 and the punching punch 231 and the restoring spring 232, is arranged in parallel with the side wall of the stretched test mold material, and can move in a direction perpendicular to the side wall of the test mold material.

[0073] Specifically, the upper part of the movable element 233 of the embodiment is fitted with the bottom inclined surface of the upper top rod 220, wherein in the closed mold state, the upper top rod 220 pushes the movable element 233 to move in a direction perpendicular to the inclined surface and close to the test mold material, thereby pushing the punching punch 231 to pass through the side wall of the stretched test mold material; in the open mold state, the restoring spring 232 pushes the movable element 233 to move in a direction away from the punching direction by the elastic force, thereby enabling the punching punch 231 to be separated from the punched part.

[0074] It should be noted that the conventional stamping die is generally used for machining the upper surface and the lower surface of the part, that is, for punching through holes on the upper and lower surfaces of the part and stamping the part into various shapes. However, in actual application, in addition to machining the upper and lower surfaces, the part also needs to be punched with a through hole on the side surface, which is difficult to achieve directly by using the original stamping die. Therefore, the punching mechanism of the embodiment enables the punching punch 231 to pass through the punched part, so that a through hole 1000 can also be formed on the side surface of the punched part, and a through hole arranged on the side surface of the product can be punched in one set of die, further improving the production efficiency of the die.

[0075] In some embodiments, the bending mechanism comprises: a third upper clamping plate 310 arranged at the bottom of the upper die seat 10; a second upper stripper plate 320 arranged at the bottom of the third upper clamping plate 310, and the bottom of the second upper stripper plate 320 is provided with a first pressing surface; an upper die isoperimetric sleeve screw 330, one end of which is arranged in the upper die seat 10, and the other end penetrates through the third upper clamping plate 310 and extends into the second upper stripper plate 320; a second lower stripper plate 340 arranged at the bottom of the second upper stripper plate 320, the bottom of the second lower stripper plate 340 is provided with a second pressing surface matched with the first pressing surface, and the two sides of the second lower stripper plate 340 are provided with bending punches 341 capable of moving in a vertical direction; a lower die isoperimetric sleeve screw 350, one end of which is arranged in the lower die seat 20, and the other end extends into the second lower stripper plate 340; in the closed mold state, the first pressing surface cooperates with the second pressing surface, and the bending punch 341 moves towards the second upper clamping plate 210, thereby bending the corresponding position of the test mold material after side punching by 90 degrees.

[0076] The bending mechanism of the embodiment is sequentially provided with a third upper clamping plate 310, a second upper stripper plate 320 and a second lower stripper plate 340 between the upper die holder 10 and the lower die holder 20 from top to bottom, and the test die material, i.e. the stamping part, is placed between the second upper stripper plate 320 and the second lower stripper plate 340. It should be noted that the upper die holder 10 and the lower die holder 20 are respectively provided with an upper die equal-height sleeve screw 330 and a lower die equal-height sleeve screw 350, and specifically the upper die equal-height sleeve screw 330 penetrates the third upper clamping plate 310 from the inside of the upper die holder 10 downward and extends to be arranged in the inside of the second upper stripper plate 320, and the lower die equal-height sleeve screw 350 extends upward from the inside of the lower die holder 20 to be arranged in the inside of the second lower stripper plate 340. During the stamping process, the upper die equal-height sleeve screw 330 and the lower die equal-height sleeve screw 350 cooperate with each other to make the stress of the stamping process uniform. At the same time, the arrangement of the upper die equal-height sleeve screw 330 effectively ensures that the second upper stripper plate 320 remains equal-height and stable, so that the heights of various positions are consistent during the working process; the arrangement of the lower die equal-height sleeve screw 350 also ensures that the second lower stripper plate 340 is equal-height and stable, preventing the stamping part from tilting during the bending process and affecting the bending effect.

[0077] It should also be noted that the upper die holder 10 and the lower die holder 20 of the embodiment are respectively provided with matching first and second pressing surfaces, and when the upper die holder 10 is punched downward, the first and second pressing surfaces cooperate with each other to enable the test die material to be stamped into a target shape. In the embodiment, the main body of the first pressing surface is in a trapezoidal structure, and downward-pointing sharp corner structures are symmetrically arranged at the two sides of the bottom of the trapezoidal structure, and the position of the trapezoidal structure away from the sharp corner structure is in a horizontal linear structure, and the second pressing surface of the embodiment is matched with the shape of the above-mentioned first pressing surface. Furthermore, the second lower stripper plate 340 of the embodiment is symmetrically provided with bending punches 341 capable of moving in the vertical direction at the two sides, and the bottoms of the bending punches 341 at the two sides are arranged on the lower die holder 20. When the mold is in an open state, the top of the bending punch 341 abuts against the horizontal linear position of the second pressing surface, and when the mold is in a closed state, the bending punches 341 at the two sides move toward the position of the second upper stripper plate 320, so that the corresponding horizontal plane of the stamping part is bent upward by 90 degrees, i.e. a lamp disc shape C with bending is stamped out. After bending and forming, the feeding mechanism 400 is used to feed the mold to the outside end in the open state, as shown in the figure, the stamping part C' is fed and pushed to the right in the direction of the arrow in the figure, and the stamping part D' is pushed out of the mold to the outside end, thus completing the processing of the entire product stamping part. Figure 6

[0078] In some embodiments, the top of the second upper stripper plate 320 is correspondingly provided with a first rectangular spring 360; the first rectangular spring 360 can apply pressure to the second upper stripper plate 320 when the mold is in a closed state.

[0079] ​In the embodiment, the upper die holder 10 is further provided with a first rectangular spring 360. Specifically, the top end of the first rectangular spring 360 is located inside the upper die holder 10, the bottom end penetrates through the third upper clamping plate 310 and extends to the second upper stripper plate 320. By arranging the first rectangular spring 360 to act on the second upper stripper plate 320, a downward thrust can be provided for the second upper stripper plate 320, and at the same time, a buffer force can be provided at the moment of mold closing to reduce the impact between the upper die holder 10 and the lower die holder 20.

[0080] In some embodiments, the bottom of the second lower stripper plate 340 is correspondingly provided with a second rectangular spring 370. The second rectangular spring 370 can exert a pressure on the second lower stripper plate 340 in the closed mold state.

[0081] In the embodiment, the lower die holder 20 is further provided with a second rectangular spring 370. Specifically, the bottom end of the second rectangular spring 370 is located inside the lower die holder 20 and extends upward to the bottom of the second lower stripper plate 340 to provide an upward thrust for the second lower stripper plate 340. At the same time, a buffer force can be provided at the moment of mold closing to protect the mold structure.

[0082] In summary, under the action of the lamp processing mold of the present application, the lamp chassis can be accurately stretched to form a special convex bending structure, which can be directly used for stable installation of the hardware chassis. The mold of the present application integrates stretching, punching and bending in one set, and the stretching stamping part 1, the punching stamping part 2 and the bending stamping part 3 are as shown in Figure 8 The efficiency of the mold processing of the present application can reach 30 pieces per minute and 1800 pieces per hour, which can improve the production efficiency and significantly reduce the production cost to achieve the dual goals of cost reduction and efficiency improvement.
