Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to a rotatable lamp panel stamping die. Background Technology

[0002] As the lighting industry upgrades its demands for product functionality and appearance design, rotatable lamp panels are increasingly widely used in home and commercial lighting because they can flexibly adjust the direction of light. These lamp panels are usually made of aluminum alloy sheets or galvanized steel sheets with a thickness of 100 mm. Stamping dies are usually required in the processing of these lamp panels. However, existing lamp panel stamping dies still have certain defects in use.

[0003] For example, the continuous stamping die for the housing of a fire-fighting lamp proposed in application number CN202022471594.8 includes a base and a lower die; an inverted U-shaped fixing frame is fixedly installed on the upper surface of the base, and a hydraulic cylinder is fixedly installed in the middle of the upper surface of the fixing frame. The hydraulic output end of the hydraulic cylinder is connected to the hydraulic input end of the hydraulic telescopic rod. In actual use, after stamping the lamp panel, burrs are easily generated on its bottom surface, which will also cause a decrease in the fit during subsequent assembly, reducing the use effect and functionality of the existing stamping die.

[0004] Therefore, we proposed a rotatable lamp panel stamping die to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable lamp panel stamping die to solve the problem mentioned in the background art that burrs are easily generated on the bottom surface after stamping, affecting the assembly fit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotatable lamp panel stamping die, including a base plate and a top plate, a fixed seat is fixedly installed on the top surface of the base plate, a fixed die is fixedly installed on the top surface of the fixed seat, a discharge hole is opened on the top of the fixed die, and a rotary grinding mechanism is connected to the outer ring of the fixed die.

[0007] A telescopic buffer mechanism is installed at the bottom of the base plate, and a moving mold is installed at the bottom end of the telescopic buffer mechanism.

[0008] A telescopic punching mechanism is fixedly installed on the top rear end of the fixed base.

[0009] Preferably, the rotary polishing mechanism includes a polishing ring rotatably mounted on the outer ring of a fixed mold, a driven gear ring fixedly mounted on the bottom outer ring of the polishing ring, a drive gear meshing with the front side of the driven gear ring, a drive motor fixedly mounted inside the front end of the fixed base, and the shaft end of the drive motor fixedly connected to the drive gear.

[0010] Preferably, the top end of the polishing ring is in close contact with the bottom end of the lamp panel, and the polishing ring polishes the bottom surface of the lamp panel to achieve a deburring effect when it rotates.

[0011] With the above-mentioned structure, the rotary grinding mechanism drives the drive gear to mesh with the driven gear ring through the drive motor, driving the grinding ring to rotate around the outer ring of the fixed mold. By utilizing the tight fit between the top of the grinding ring and the bottom of the lamp panel, the bottom surface of the stamped panel can be ground evenly, completely solving the problems of excessive assembly tightness and rotation jamming, and ensuring stable assembly gap to meet the requirements of rotational coaxiality.

[0012] On the other hand, it eliminates the need for subsequent manual polishing, avoids damage to the panel surface caused by manual polishing, and ensures that the surface roughness of the panel meets the usage standards.

[0013] Preferably, the telescopic buffer mechanism includes a limiting seat fixedly installed on the bottom surface of the top plate, the limiting seat having a limiting groove inside, a lifting column being slidably installed inside the limiting groove, the bottom end of the lifting column being fixedly connected to the moving mold, and a buffer spring being sleeved on the outer ring of the lifting column between the moving mold and the limiting seat.

[0014] With the above-mentioned structural design, the telescopic buffer mechanism uses the limiting groove to guide the lifting column, and in conjunction with the outer ring buffer spring, when the moving mold is pressed down to clamp, the buffer spring absorbs the impact force through elastic deformation, avoids rigid collision between the moving mold and the fixed mold, and reduces stress concentration in the thin plate.

[0015] The buffer structure can also reduce impact wear on the moving and fixed molds, extend the service life of the core components of the mold, and reduce maintenance and replacement costs.

[0016] Preferably, the telescopic punching mechanism includes a mounting base fixedly installed on the top surface of the rear end of the fixed seat, a fixed plate fixedly installed on the top surface of the mounting base, a hydraulic rod fixedly connected to the rear side of the fixed plate, and the shaft end of the hydraulic rod being slidably connected to the fixed plate through it.

[0017] Preferably, the telescopic punching mechanism further includes a slide block fixedly connected to the end of the hydraulic rod shaft. The two ends of the slide block are slidably connected to a limiting seat. The bottom end of the limiting seat is fixedly connected to the top surface of the mounting seat. A slide rail is fixedly installed on the top surface of the mounting seat. The slide block is slidably connected to the slide rail. A punching block is fixedly installed at the front end of the slide block.

[0018] With the above-mentioned structure, the telescopic punching mechanism drives the slide block to slide along the slide rail through the hydraulic rod. Combined with the guiding and positioning of the limiting seat, the punching block completes the punching of the irregular notch of the panel. The double guiding structure of the slide block ensures the accuracy of the punching position and reduces the scrap rate of the panel.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the rotatable lamp panel stamping mold;

[0020] 1. This rotatable lamp panel stamping die effectively solves the pain points of traditional stamping and ensures the performance of the product and the die by using a rotary grinding mechanism and a telescopic buffer mechanism. The rotary grinding mechanism is driven by a motor to rotate the grinding ring around the fixed die. With the close contact between the grinding ring and the bottom of the panel, the burrs on the bottom surface after stamping can be removed evenly. This avoids the problems of excessive assembly tightness and rotation jamming caused by burrs, ensures the assembly gap and rotation coaxiality, and eliminates the need for manual grinding. It also prevents damage to the panel surface caused by manual operation and ensures that the surface roughness meets the standards. The telescopic buffer mechanism uses the guide of the limit groove and the elastic deformation of the buffer spring to absorb the impact force when the moving die is pressed down, avoids rigid collision between the moving die and the fixed die, reduces stress concentration on thin plates, reduces impact wear on the core components of the die, extends service life, and reduces maintenance and replacement costs.

[0021] 2. The telescopic punching mechanism of the mold further improves the stamping accuracy and production stability. It drives the slide block to slide along the slide rail through the hydraulic rod. Combined with the double guide positioning of the limiting seat, the stamping block can accurately complete the stamping of the irregular notch of the panel, effectively reducing the scrap rate of the panel caused by positioning deviation. Overall, the three mechanisms work together to not only ensure the assembly fit, dimensional accuracy and surface quality of the panel in terms of product quality, but also save manual processes, reduce scrap and mold maintenance costs in terms of production efficiency and cost control, and comprehensively improve the stamping production efficiency of rotatable lamp panels.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 The present invention provides a technical solution: a rotatable lamp panel stamping die, including a base plate 1 and a top plate 2. A fixed seat 3 is fixedly installed on the top surface of the base plate 1, and a fixed mold 4 is fixedly installed on the top surface of the fixed seat 3. A discharge hole 5 is opened on the top of the fixed mold 4. A rotary grinding mechanism is connected to the outer ring of the fixed mold 4. The rotary grinding mechanism includes a grinding ring 6 rotatably installed on the outer ring of the fixed mold 4. The top of the grinding ring 6 is tightly fitted with the bottom end of the lamp panel. When the grinding ring 6 rotates, it grinds the bottom end surface of the lamp panel to achieve a deburring effect. A driven gear ring 7 is fixedly installed on the bottom outer ring of the grinding ring 6. A drive gear 8 is meshed with the front side of the driven gear ring 7. A drive motor 9 is fixedly installed inside the front end of the fixed seat 3. The shaft end of the drive motor 9 is fixedly connected to the drive gear 8.

[0031] In the above structure design, when the lamp panel is stamped and needs to be deburred, the drive motor 9 installed inside the front end of the fixing base 3 starts. The shaft end of the drive motor 9 will drive the drive gear 8 fixedly connected to it to rotate synchronously. Since the drive gear 8 and the driven gear ring 7 fixed to the bottom outer ring of the grinding ring 6 are in a meshing state, the rotational force of the drive gear 8 will be transmitted to the driven gear ring 7, thereby driving the driven gear ring 7 and the grinding ring 6 fixed to it to rotate together.

[0032] At this time, the grinding ring 6 rotates around the outer ring of the fixed mold 4, and the top of the grinding ring 6 always keeps in close contact with the bottom surface of the lamp panel. During the continuous rotation of the grinding ring 6, friction will be generated in the contact area between its top and the bottom surface of the panel. Through this friction effect, the burrs remaining on the bottom surface of the panel after stamping can be evenly ground, and the burr removal effect of the bottom surface of the panel can be achieved, which provides a guarantee for the fit and rotational coaxiality of the subsequent panel assembly.

[0033] A telescopic buffer mechanism is installed at the bottom of the base plate 1. A moving mold 13 is installed at the bottom end of the telescopic buffer mechanism. The telescopic buffer mechanism includes a limiting seat 10 fixedly installed on the bottom surface of the top plate 2. A limiting groove 11 is opened inside the limiting seat 10. A lifting column 12 is slidably installed inside the limiting groove 11. The bottom end of the lifting column 12 is fixedly connected to the moving mold 13. A buffer spring 14 is sleeved on the outer ring of the lifting column 12 between the moving mold 13 and the limiting seat 10.

[0034] In the above-described structure, when the mold starts to perform the extrusion and clamping operation, the moving mold 13 is driven by an external force and presses vertically downward toward the fixed mold 4 on the base plate 1 to complete the clamping and positioning of the lamp panel. At this time, the lifting column 12, which is fixedly connected to the top of the moving mold 13, will slide down synchronously in the limiting groove 11 inside the limiting seat 10 fixed on the bottom surface of the top plate 2 as the moving mold 13 presses down. The limiting groove 11 strictly limits the movement direction of the lifting column 12 by limiting its lateral movement, preventing the lifting column 12 from shifting left or right, thereby ensuring that the moving mold 13 always moves smoothly along the vertical trajectory.

[0035] Subsequently, as the lifting column 12 slides down, the buffer spring 14 fitted around its outer ring will be gradually compressed. The elastic reaction force generated when the buffer spring 14 is compressed can effectively absorb the impact force generated during the downward pressing of the moving mold 13, greatly weakening the rigid collision when the moving mold 13 contacts the fixed mold 4, and reducing the stress concentration of the thin plate.

[0036] A telescopic punching mechanism is fixedly installed on the top rear end of the fixed base 3. The telescopic punching mechanism includes a mounting base 15 fixedly installed on the top rear end of the fixed base 3. A fixing plate 16 is fixedly installed on the top surface of the mounting base 15. A hydraulic rod 17 is fixedly connected to the rear side of the fixing plate 16. The shaft end of the hydraulic rod 17 is slidably connected to the fixing plate 16. The telescopic punching mechanism also includes a slide block 18 fixedly connected to the shaft end of the hydraulic rod 17. A limiting seat 19 is slidably connected to both ends of the slide block 18. The bottom end of the limiting seat 19 is fixedly connected to the top surface of the mounting base 15. A slide rail 20 is fixedly installed on the top surface of the mounting base 15. The slide block 18 is slidably connected to the slide rail 20. A punching block 21 is fixedly installed at the front end of the slide block 18.

[0037] When the lamp panel needs to be stamped with irregular notches, the hydraulic rod 17 fixed to the rear side of the mounting plate 16 on the top surface of the mounting base 15 is activated. The hydraulic rod 17 serves as a power source, and its shaft end will extend forward along the through hole of the mounting plate 16. Since the shaft end of the hydraulic rod 17 is fixedly connected to the slide 18, the extension and retraction of the shaft end will directly drive the slide 18 to move synchronously.

[0038] Secondly, during the movement of the slide block 18, it is constrained by a dual guide structure: on the one hand, the bottom surface of the slide block 18 is slidably connected to the slide rail 20 fixed on the top surface of the mounting base 15, and the slide rail 20 provides a stable lateral movement trajectory for the slide block 18, preventing the slide block 18 from shifting vertically; on the other hand, the two ends of the slide block 18 are slidably engaged with the limiting seats 19 fixed on the top surface of the mounting base 15, and the limiting seats 19 further restrict the left and right offset of the slide block 18. The dual guides work together to ensure that the slide block 18 always moves smoothly along the preset straight trajectory, avoiding stamping position deviation caused by the tilt of the slide block 18.

[0039] Finally, as the slide 18 moves forward along the guide structure, the stamping block 21 fixedly installed at its front end will simultaneously approach the lamp panel to be stamped. Finally, through the contact and extrusion between the stamping block 21 and the panel, the stamping of the irregular notch of the panel is completed. The stamped waste will be discharged through the discharge hole 5, the fixed mold 4, and the slot opened inside the fixed seat 3.

[0040] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
