Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figures 1 to 4 As shown, the agricultural photovoltaic bracket punching equipment includes a frame 1, a worktable 2 on the frame 1, a punching mechanism 3 mounted on the worktable 2, a waste collection device 4 correspondingly located below the punching mechanism 3, and positioning and clamping mechanisms 5 positioned and clamping the photovoltaic bracket downwards at the front and rear of the punching mechanism 3, respectively. Before punching, the positioning and clamping mechanisms 5 first clamp and position the photovoltaic bracket, and then the punching mechanism 3 punches the bracket. Waste material from punching is collected by the waste collection device 4. After punching is completed, the positioning and clamping mechanisms 5 are released, and the photovoltaic bracket continues to be conveyed forward a fixed length, ready for the next punching.

[0029] The punching mechanism 3 includes an upper die assembly and a lower die assembly. The upper die assembly is mounted on the frame 1, and the lower die assembly is detachably mounted on the worktable 2 via a punching base plate 31. A base plate punching channel 32 is provided through the surface of the punching base plate 31. The waste collection device 4 is located below the base plate punching channel 32. The base plate punching channel 32 allows waste to fall downwards into the waste collection device 4 for collection. The punching base plate 31 is detachably connected to the T-slot on the worktable 2 by bolts, which facilitates the replacement of the lower die assembly as a whole.

[0030] The upper die assembly includes a punching cylinder 33, the cylinder body of which is fixed to the frame 1. The telescopic end of the punching cylinder 33 is detachably equipped with a punching upper template 34. Multiple punch rods 35 are arranged along the length of the photovoltaic bracket at the bottom of the punching upper template 34. The punch rods 35 can be replaced by replacing the punching upper template 34. The lower die assembly includes a punching lower module 36. The surface of the punching lower module 36 is provided with multiple punching rod die holes 37 corresponding to the punch rods 35. During punching, the photovoltaic bracket is supported on the punching lower module 36. The punch rods 35 descend under the action of the punching cylinder 33 and are inserted into the corresponding punching rod die holes 37. The punching rod die holes 37 cooperate with the punch rods 35 to achieve punching of the photovoltaic bracket.

[0031] A guiding device is provided between the upper die assembly and the lower die assembly. The guiding device includes a punching guide post 38 fixed to the lower die assembly. The punching upper template 34 is slidably fitted onto the punching guide post 38. Through the cooperation between the punching guide post 38 and the punching upper template 34, the upper die assembly can be guided, thereby improving the punching accuracy.

[0032] The lower punching module 36 has side positioning devices on its left and right sides that abut against both ends of the photovoltaic bracket. A punching rod guide plate 39 is also provided above the lower punching module 36. The distance between the punching rod guide plate 39 and the lower punching module 36 is greater than the waist thickness of the photovoltaic bracket. The punching rod guide plate 39 is detachably connected to the side positioning devices. The surface of the punching rod guide plate 39 is provided with multiple punching rod guide holes 310 that match the punch rod 35. The punching rod guide holes 310 are adapted to the size of the punch rod 35. The punch rod 35 is always inserted into the punching rod guide hole 310 and can slide up and down along the punching rod guide hole 310 to achieve the purpose of guiding the punch rod 35. In conjunction with the guiding device, it can further improve the punching accuracy.

[0033] In this embodiment, six punch rods 35 are evenly distributed, and correspondingly, six punch rod die holes 37 and six punch rod guide holes 310 are provided, ensuring that six mounting holes can be processed on the photovoltaic bracket at one time. The bottom end of the punch rod 35 has a V-shaped structure.

[0034] To facilitate the processing of mounting holes of different sizes and spacings on photovoltaic brackets, existing technologies generally require the replacement of the entire lower mold, which results in high equipment costs and is complex and difficult to replace. Therefore, this embodiment improves the punching lower module 36 by splitting the existing integrated lower mold into two parts. Preferably, the punching lower module 36 includes a fixed support mold 36a, the top of which is provided with a detachable punching mold 36b. Multiple punching die holes 37 are provided on the detachable punching mold 36b. A lower mold punching channel 36c is provided through the fixed support mold 36a, and the lower mold punching channel 36c extends along the length direction of the photovoltaic bracket. The fixed support mold 36a serves merely as a support base, used to raise the height of the punching lower module 36 to accommodate the height of the photovoltaic bracket. The lower die punching channel 36c on it is used to avoid the punch rod 35. The detachable punching die 36b is fixed to the fixed support mold 36a with bolts. The punching die hole 37 is located on the detachable punching die 36b. By providing mounting holes of different specifications or in different numbers on the detachable punching die 36b, various specifications of detachable punching dies 36b can be formed to meet different processing requirements. When processing mounting holes of different specifications, it is not necessary to replace the entire punching lower module 36; instead, only the detachable punching die 36b needs to be removed and replaced. Simultaneously, the corresponding punching guide hole 310, the punching upper template 34, and the punch rod 35 can be replaced, thus meeting the need for multiple uses with a single machine. The replacement method is simple and low-cost.

[0035] The two side positioning devices work together to position the photovoltaic bracket in the left and right directions, and also serve as the mounting structure for the punch guide plate 39 bracket. Each side positioning device includes auxiliary side plates 311 located on the left and right sides of the punching lower module 36. Side limiting wheels 312, rotatably supported on the side surface of the photovoltaic bracket, are rotatably mounted on the inner side of each auxiliary side plate 311. At least two side limiting wheels 312 are arranged along the length of the same auxiliary side plate 311, and more can be arranged. The side limiting wheels 312 on the left and right sides are symmetrically positioned to simultaneously contact and abut against the left and right end faces of the photovoltaic bracket, thus positioning the photovoltaic bracket in the left and right directions and ensuring the accuracy of the punching position. The auxiliary side plate 311 has a mounting groove 313 at its top end. The punch guide plate 39 has guide plate brackets 314 at both ends, positioned within the mounting groove 313. The width of the mounting groove 313 is greater than the width of the guide plate brackets 314. The auxiliary side plate 311 has limiting screws 315, the inner end of which abuts against the outside of the guide plate brackets 314. A fixing screw 316 is also provided between the auxiliary side plate 311 and the guide plate brackets 314. The limiting screws 315 on both sides work together to adjust the position of the guide plate brackets 314, thereby adjusting the left and right positions of the punch guide plate 39. This ensures that the position of the punch guide hole 310 accurately corresponds to the punch rod 35. After adjustment, the plate is fixed using the two fixing screws 316. The cooperation of the limiting screws 315 and the fixing screws 316 facilitates the disassembly, replacement, and positioning of the punch guide plate 39.

[0036] The positioning and pressing mechanism 5 includes a positioning bracket 51, a positioning cylinder 52 is fixed at the top of the positioning bracket 51, a positioning pressure plate 53 is fixedly connected to the telescopic end of the positioning cylinder 52 facing downward, an auxiliary support block 54 is provided below the positioning pressure plate 53, and the top of the auxiliary support block 54 is at the same horizontal plane as the top of the punching module 36.

[0037] The waste collection device 4 includes a waste box 41. The workbench 2 is provided with a waste hole 42 located below the punching mechanism 3 and above the waste box 41. The waste box 41 is inclined and its inclined bottom end extends to the side of the punching equipment.

[0038] The working principle of this embodiment is as follows:

[0039] When the photovoltaic bracket is transported to this equipment, the inner groove surface of the photovoltaic bracket slides forward along the auxiliary support block 54 and passes through the gap between the detachable punch die 36b and the punch guide plate 39. When passing through, the left and right side limit wheels 312 abut against the left and right sides of the photovoltaic bracket. When the photovoltaic bracket moves into place, the transport stops, and the front and rear positioning cylinders 52 extend, driving the positioning pressure plate 53 to descend and press on the surface of the photovoltaic bracket, so that the inner surface of the photovoltaic bracket is tightly attached to the upper surface of the detachable punch die 36b, and the positioning is completed in cooperation with the left and right side limit wheels 312.

[0040] Then, the punching cylinder 33 actuates, causing the upper punching template 34 and the punch rod 35 to descend. The punch rod 35 descends along the punch rod guide hole 310, penetrates the photovoltaic bracket, and enters the lower die punch rod channel 36c through the punch rod die hole 37. The generated waste material falls into the waste box 41 through the waste material hole 42 for collection. After punching is completed, the punching cylinder 33 actuates, causing the upper punching template 34 and the punch rod 35 to rise and reset. The positioning cylinder 52 drives the positioning pressure plate 53 to retract, and the photovoltaic bracket continues to be conveyed forward to a fixed length, ready for the next punching.

[0041] The vertical and horizontal positioning of the photovoltaic bracket is achieved by the positioning cylinder 52 and the positioning pressure plate 53. The horizontal positioning of the photovoltaic bracket is achieved by the side limiting wheel 312. The positioning method is simpler, and the vertical and horizontal positioning is located outside the punching mechanism 3, which can reduce the structural complexity of the punching mechanism 3.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
