Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to a stamping die for a photovoltaic module frame. Background Art

[0002] Before the photovoltaic module frame leaves the factory, it is necessary to punch riveting points on the long-side aluminum frame by stamping to facilitate its assembly with corner codes. The currently used stamping die directly punches the riveting points, and the size deviation of the riveting points of the processed photovoltaic module is relatively large, which affects the subsequent assembly and overall performance. Moreover, the frame is prone to deformation during the stamping process, affecting the sealing performance and structural strength of the photovoltaic module; due to the use of a circular riveting punch, after the short frame is assembled with the corner code, it will be affected by the corner code during the stamping process, resulting in uneven pressure distribution and stress concentration during riveting. Therefore, problems such as material stamping cracks or size deformation are likely to occur at the riveting part, affecting the stability and safety of the photovoltaic module;

[0003] In addition, the existing stamping die mainly relies on manual operation, lacks automatic control, has low productivity, high labor costs, and the processing quality is affected by human factors, resulting in unstable quality. Summary of the Invention

[0004] The purpose of the utility model is to provide a stamping die for a photovoltaic module frame to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A stamping die for a photovoltaic module frame, the stamping die includes an upper die;

[0006] A lower die; end benchmarks and lateral benchmarks are provided at both ends of the lower die, and an inner cavity lower die slider is installed outside the end benchmark through a push cylinder and a screw rod. The push cylinder pushes the inner cavity lower die slider into the workpiece to be processed through the screw rod;

[0007] The upper die is integrated with a riveting punch, and the riveting punch is configured with a booster cylinder connected to a controller. The booster cylinder drives the riveting punch into the riveting area of the workpiece to be processed through air pressure.

[0008] Preferably, the upper half of the riveting punch is in the shape of a cylinder or a cuboid, and the lower part is trapezoidal. The cross-section of the lower part of the riveting punch is a trapezoid with a long outer side and a short inner side.

[0009] Preferably, the front end of the inner cavity lower die slider is frustum-shaped, and a reinforcing plate is provided on one side or both sides of its upper end surface.

[0010] Preferably, a guiding through groove is opened on the end benchmark, and the outer surface of the inner cavity lower die slider is slidably connected with the inner surface of the guiding through groove. The inner cavity lower die slider passes through the guiding through groove into the photovoltaic module frame.

[0011] Preferably, the outer diameter of the screw is smaller than the width of the inner cavity lower die slider.

[0012] The technical effects and advantages of the present utility model are as follows:

[0013] 1. Through the design of the datum, the precise alignment between the mold and the workpiece to be processed is ensured, improving the stability and accuracy of the stamping process. By pushing the cylinder and the inner cavity lower die slider deep into the workpiece to be processed, the precise profiling of the inner cavity of the frame is achieved, which helps to maintain the shape stability of the frame during stamping, reduce deformation, and improve product quality.

[0014] 2. The integrated riveting punch in the upper mold can directly perform riveting on the frame, reducing the number of mold replacements and adjustments, and lowering production costs. Driven by air pressure, it provides stable and powerful punching force, with the advantages of fast response and precise control, ensuring the smooth progress of the riveting process while reducing wear on the mold and equipment.

[0015] 3. The boosting cylinder is connected to the controller, realizing the automatic control of the stamping process. This intelligent control system can automatically adjust the punching force and stroke according to preset parameters, ensuring the consistency of processing quality. At the same time, the automatic control also reduces the labor intensity of operators and improves production safety.

[0016] 4. The combined action of the inner cavity lower die slider and the precise datum system effectively reduces the deformation of the frame during stamping, which helps to ensure the geometric accuracy and surface quality of the frame, improving the overall performance and service life of the photovoltaic module.

[0017] 5. By adjusting the stroke of the pushing cylinder and the screw, the position and depth of the inner cavity lower die slider can be conveniently adjusted to adapt to the photovoltaic module frames of different sizes and shapes, improving the versatility and flexibility of the mold.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-3 shown in a specific implementation manner of a stamping die for a photovoltaic module frame of the present invention: The stamping die includes an upper die 1;

[0024] a lower die 2; both ends of the lower die 2 are provided with an end reference 31 and a lateral reference 32. Outside the end reference 31, an inner cavity lower die slider 6 is installed through a pushing cylinder 4 and a screw 5. The pushing cylinder 4 pushes the inner cavity lower die slider 6 into the workpiece to be processed through the screw 5; the upper die 1 is integrated with a riveting punch 7, and the riveting punch 7 is configured with a boosting cylinder 8 connected to a controller. The boosting cylinder 8 drives the riveting punch 7 into the riveting area of the workpiece to be processed through air pressure; the upper half of the riveting punch 7 is in a cylindrical or cuboid shape, and the lower part is trapezoidal. The cross-section of the lower part of the riveting punch 7 is a trapezoid with a long outer side and a short inner side; the front end of the inner cavity lower die slider 6 is frustum-shaped, and a reinforcing plate 9 is provided on one side or both sides of its upper end surface; a guiding through groove 33 is opened on the end reference 31, and the outer surface of the inner cavity lower die slider 6 is slidably connected to the inner surface of the guiding through groove 33. The inner cavity lower die slider 6 passes through the guiding through groove 33 into the photovoltaic module frame; the outer diameter of the screw 5 is smaller than the width of the inner cavity lower die slider 6.

[0025] Working process:

[0026] Place the photovoltaic module frame 10 to be processed on the lower die 2, and ensure that both ends of the frame are aligned with the end reference 31 and the lateral reference 32 to ensure the accuracy of processing;

[0027] Through the action of the pushing cylinder 4, the screw 5 pushes the inner cavity lower die slider 6 to slide along the guiding through groove 33 until the front end (frustum-shaped part) of the inner cavity lower die slider 6 completely enters the inner cavity of the frame. This process ensures the stability of the frame during subsequent processing and prevents the processing quality from being affected by frame deformation;

[0028] Under the control of the controller, the boosting cylinder 8 is started, and the riveting punch 7 is driven to descend through air pressure. The riveting punch 7 enters the riveting area of the frame with its special shape (the upper half is cylindrical or cuboid, and the lower part is a trapezoid with a long outer side and a short inner side) to complete the riveting operation; this design makes the riveting process more uniform, reduces stress concentration, and improves the processing quality;

[0029] After the riveting is completed, the boosting cylinder 8 releases the air pressure, and the riveting punch 7 resets. At the same time, the pushing cylinder 4 moves in the reverse direction, and the inner cavity lower die slider 6 is withdrawn from the inner cavity of the frame through the screw rod 5 and returns to the initial position. At this time, the processed photovoltaic module frame can be taken out for the next processing or inspection.

[0030] Through the settings of the end reference and the lateral reference, the present utility model ensures the precise positioning of the frame during the processing, thereby improving the processing accuracy. The design of the inner cavity lower die slider effectively prevents the deformation of the frame during the processing, ensuring the stability of the processing process and the processing quality. The special shape design of the riveting punch makes the riveting process more uniform, reduces stress concentration, improves the riveting effect, and extends the service life of the photovoltaic module. The entire processing process controls the actions of the boosting cylinder and the pushing cylinder through the controller, realizing automated operation and improving production efficiency. The mold design is compact, the cooperation between components is tight, and it is easy to disassemble and replace, facilitating daily maintenance and repair.

[0031] In summary, the present utility model has significant advantages and effects in the processing of the photovoltaic module frame, and can effectively improve the processing quality and production efficiency.
