Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a supporting connector of a photovoltaic tracking bracket. Background Art

[0002] A solar photovoltaic tracking system harnesses the power of sunlight to generate electricity. It adjusts the angle of the photovoltaic panels in real time based on the sun's position to maximize solar energy absorption. Bracing connectors, key components connecting the photovoltaic panels to the tracking bracket, not only bear the weight of the panels but also ensure the stability and adjustability of the bracket.

[0003] Bracing connectors often have complex shapes and structures to accommodate the installation and positioning of photovoltaic panels. Bracing connectors often feature holes, chamfers, bumps, or other features. Once the die type and basic parameters are determined, the stamping press can efficiently and continuously repeat the same processing steps, ensuring consistent part accuracy in large-scale production. Furthermore, by optimizing layout layout and calculating material utilization, the stamping process can be optimized to minimize material consumption.

[0004] Traditionally, diagonal brace connectors are processed using a press brake. This process begins by placing the processed sheet metal on a workbench and clamping it with a clamping fixture. Next, the press brake parameters are set based on the required shape and dimensions of the diagonal brace connector and processing begins. Finally, if the diagonal brace connector has holes, these holes must be machined after the bending step. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-9 In an embodiment of the present invention, a stamping die for a supporting connector of a photovoltaic tracking bracket comprises a lower die base 1 and an upper die base 3 slidably connected to the upper portion of the lower die base 1. A stamping space for accommodating materials is provided between the lower die base 1 and the upper die base 3. The lower die base 1 and the upper die base 3 are sequentially provided with a feeding portion, a first punching portion, a first bending portion 10, a second punching portion, a second bending portion, and a cutting portion 19 from one end to the other end. In this embodiment, a lower template 6 is provided on the lower die base 1, and the lower dies of the first punching portion, the first bending portion 10, and the second punching portion are all located on the lower template 6. An upper template 8 is provided at the lower part of the upper die base 3, and the upper die portions of the first punching portion, the first bending portion 10, the second punching portion, the second bending portion, and the cutting portion 19 are all located at the lower part of the upper template 8.

[0035] The feeding part includes a material receiving plate 5 arranged at one end of the lower die base, and material guide plates 2 are provided on both sides of the upper end of the material receiving plate 5, and a channel for feeding is formed between the material guide plates 2 on both sides.

[0036] The first blanking part includes a first blanking die 7 arranged on the lower die base 1 and a first blanking punch 9 arranged on the upper die base 3. The first blanking die 7 and the first blanking punch 9 are symmetrically arranged in two groups along the feed direction. The lower part of the first blanking die 7 passes through the lower die base 1 to form a discharge hole. In addition, a first punching pin 23 and a second punching pin 24 are provided at the first blanking part.

[0037] The first bending part 10 includes a first bending die 14 arranged on the lower die base 1 and a first bending punch 11 located at the lower part of the upper die base 3. The first bending punch 11 is a rectangular structure. The first bending die 14 includes two symmetrically arranged rectangular blocks to form a bending groove for accommodating the first bending punch 11 and the material.

[0038] The second blanking part includes a second blanking die 12 and a second blanking punch 13. The second blanking die 12 and the second blanking punch 13 are symmetrically arranged in two groups along the feeding direction, and a gap is set between the two groups of second blanking dies 12 and second blanking punches 13.

[0039] The second bending part includes a second bending die 15 located on the lower die base 1 and a second bending punch 16 located at the lower part of the upper die base 3. The second bending die 15 includes two rectangular blocks. The two rectangular blocks of the second bending die 15 constitute a bending groove for accommodating the second bending punch 16. The second bending punch 16 is provided with two bending rectangular blocks. The lower die base 1 is movably connected with a material receiving plate 18 through a plurality of supporting spring assemblies 20. The material receiving plate 18 is located in the bending groove in the second bending die 15 and extends to one end to the cutting part 19. A bending die groove for accommodating the second bending punch 16 is formed between the material receiving plate 18 and the second bending die 15 on both sides.

[0040] A plurality of first guide assemblies and a second guide assembly 22 are provided between the upper die base 3 and the lower die base 1 . The first guide assembly includes a first guide hole 4 and a first guide column 21 . The first guide column 21 is inserted into the first guide hole 4 .

[0041] When the utility model is in use, the sheet to be punched is inserted into the mold through the receiving plate 5 and the guide plate 2. First, the sheet enters the first punching part for punching. When the first punching part is working, the first punching punch 9 presses downward and cooperates with the first punching die 7 to punch a groove 26 on the sheet. At the same time, the first hole 29 and the second hole 30 are processed on the sheet. The number and position of the first hole 29 and the second hole 30 can be arranged as needed, and the punched waste is discharged from the lower part.

[0042] Then the lower die base 1 and the upper die base 3 are separated, and the sheet material continues to move forward by the length of one work station. At this time, the sheet material after the first punching enters the first bending part 10. At this time, the residues on both sides formed after punching on the sheet material will stop on the first bending die 14, and then with the downward movement of the first bending punch 11, the residues on both sides are bent in cooperation with the first bending die 14 to form the first bend 27, and the sheet material on the rear side is punched through the first punching part.

[0043] Then the lower die base 1 and the upper die base 3 are separated again, and the sheet material continues to move forward the length of one workstation. At this time, the sheet material after the first punching and the first bending enters the second punching part, and is punched by the second punching die 12 and the second punching punch 13 in the second punching part, that is, the sheet material between adjacent support body 25 is punched. Since there is a gap between the second punching punches 13 on both sides, the width of the gap is the same as the width of the support body 25. Therefore, this punching will not completely cut off the adjacent support body 25, but will punch the bending part of the next workstation to prepare for the second bending.

[0044] Then the lower die base 1 and the upper die base 3 are separated again, and the sheet material continues to move forward the length of one work station. At this time, the sheet material after a punching, a first bending, and a second punching part enters the second bending part, where the support member main body 25 is supported by the material support plate 18, and the second bending die 15 and the second bending punch 16 are used to bend both sides of the sheet material to form a second bend 28. Due to the second punching, the bending here will not affect the sheet material undergoing the second punching at the rear. After the second bending, the support member is processed and formed, and then continues to move forward with the sheet material, and then the cutting knife of the cutting part 19 is used to cut off the connecting section left after the second cutting, so that the processed support member can be separated from the support member to be processed and fall into the material box.

[0045] During normal processing of this application, the sheet material continuously enters the processing mold, and multiple processing stations in the mold can continue to work simultaneously, greatly increasing production efficiency.
