Description

PV support tubing is a core component of a PV support system, primarily used to support PV modules and fix their position. It must possess sufficient strength. The processing of PV support tubing is a critical step in PV support production; its quality directly affects the strength, stability, and installation efficiency of the support system. For example, connecting holes are machined at designated locations on the tubing, and the size of these holes varies depending on the tubing's dimensions and the connection method.

[0003] Because current punching equipment cannot easily change punches according to the hole diameter, it is not possible to complete the processing of holes of different diameters in one go. It is necessary to change equipment for secondary processing, which not only reduces processing efficiency but also affects processing accuracy. Therefore, a multifunctional photovoltaic bracket tube processing equipment is proposed to address the above problems. Utility Model Content

[0025] Please see Figures 1-4 As shown, a multifunctional photovoltaic bracket tube processing equipment includes a punching machine frame 1, a mounting frame 4 on the punching machine frame 1, the mounting frame 4 being U-shaped, one side plate of the mounting frame 4 being slidably mounted on the inner side of the side plate of the punching machine frame 1 via a slide rail, a rotating rod 5 being rotatably mounted between opposite sides inside the mounting frame 4, the rotating rod 5 being fixedly passed through a punch fixing seat 6, the upper and lower parts of the punch fixing seat 6 being detachably mounted with punch bodies 10, a first cylinder 3 being fixedly mounted on the upper part of the top plate of the punching machine frame 1, one end of the piston rod of the first cylinder 3 being fixedly connected to the upper plate of the mounting frame 4, two clamping strips 21 being symmetrically and slidably mounted on the upper part of the lower plate of the punching machine frame 1, each clamping strip 21 having an installation groove 22 on opposite sides, and multiple limiting rollers 12 being movably mounted in each of the two installation grooves 22.

[0026] Through the design of cylinder 3, mounting frame 4, rotating rod 5, punch fixing seat 6, clamping bar 21 and limiting roller 12, the two clamping bars 21 can be moved to clamp and limit the pipe during punching. While clamping and limiting the pipe, the limiting roller 12 can move the pipe linearly for step processing, which helps to ensure processing accuracy. Under the push of cylinder 3, mounting frame 4 will drive punch fixing seat 6 to slide down. The punch body 10 on punch fixing seat 6 punches the pipe. The rotating rod 5 can flip punch fixing seat 6 to interchange the positions of the two punch bodies 10, which is convenient for changing punches to process holes of different diameters. The punches required for a batch of pipes can be changed in advance on punch fixing seat 6, which is convenient for quick punch change processing and improves processing efficiency and processing accuracy.

[0027] Among them, a gear 13 is fixedly inserted through one end of the rotating rod 5, and a rack 14 is engaged with the upper part of the gear 13. One side of the rack 14 is slidably installed inside a side plate of the mounting frame 4 via a slide rail.

[0028] To facilitate the replacement of the punch body 10, the rack 14 can be driven to slide and drive the gear 13 to rotate. The gear 13 will drive the rotating rod 5 to rotate and flip the punch holder 6, making it easy to quickly replace the punch.

[0029] Among them, a connecting rod 16 is fixedly connected to one end of the rack 14, and a second cylinder 15 is fixedly installed on the outside of a side plate body connected to the rack 14. One end of the piston rod of the second cylinder 15 is fixedly connected to one end of the connecting rod 16.

[0030] To facilitate the sliding of rack 14, starting cylinder 15 will push the connecting rod 16 connected to rack 14 to move linearly, thereby causing rack 14 to slide and facilitating the rotation of rod 5.

[0031] The punch body 10 has a locking block 11 fixed at one end, a limit plate 9 fixed on the other side of the locking block 11, and a screw 8 fixed on the other side of the limit plate 9.

[0032] To facilitate the installation of the punch body 10, the designed screw 8 can be threaded onto the punch fixing seat 6, and the screw 8 can be locked by the locking block 11. After the screw 8 is locked, the limiting plate 9 will fit tightly against the surface of the punch fixing seat 6, which facilitates the installation of the punch.

[0033] Among them, the upper and lower surfaces of the punch fixing seat 6 are provided with screw holes 7 corresponding to the screw 8, and the locking block 11 is hexagonal.

[0034] In order to achieve the connection of the screw 8 to the punch fixing seat 6, the screw hole 7 is provided to facilitate the threaded connection of the screw 8, and the hexagonal design of the locking block 11 makes it easy to tighten with a wrench, improving the comfort of installation.

[0035] Among them, the upper surface of the lower plate of the punching machine frame 1 is provided with a sliding groove 2, and two sliders 18 are slidably installed in the sliding groove 2. The lower surfaces of the two clamping bars 21 are fixedly connected to the upper surfaces of the two sliders 18 respectively.

[0036] In order for the two clamping bars 21 to clamp the pipe, the two sliders 18 can be driven to slide in opposite directions in the groove 2 at the same time, which will drive the clamping bars 21 to clamp and limit.

[0037] A bearing seat 17 is fixedly installed at one end of the slide groove 2. A positive and negative double-threaded screw 19 is rotatably installed in the slide groove 2 through the bearing seat 17. Two sliders 18 are threadedly engaged with the first threaded part and the second threaded part of the positive and negative double-threaded screw 19, respectively.

[0038] In order to achieve simultaneous reverse sliding of the two sliders 18 in the slide groove 2, the positive and negative double screw 19 is driven to rotate. With the cooperation of the threads, the two sliders 18 will slide in opposite directions in the slide groove 2 at the same time, which is convenient for clamping and limiting.

[0039] The other end of the positive and negative double-threaded screw 19 rotates through the outside of the slide groove 2, and the end of the positive and negative double-threaded screw 19 that extends to the outside is fixedly installed with a rocker plate 20.

[0040] To facilitate the rotation of the double-threaded screw 19, it can be driven to rotate by shaking the set rocker plate 20, which is convenient to use and allows for quick positioning.

[0041] Working principle: Through the design of cylinder 3, mounting frame 4, rotating rod 5, punch fixing seat 6, clamping bar 21 and limiting roller 12, the two clamping bars 21 can be moved to clamp and limit the pipe during punching. While clamping and limiting the pipe, the limiting roller 12 can move the pipe linearly for step processing, which helps to ensure processing accuracy. Under the push of cylinder 3, the mounting frame 4 will drive the punch fixing seat 6 to slide down. The punch body 10 on the punch fixing seat 6 punches the pipe. The rotating rod 5 can flip the punch fixing seat 6 to interchange the positions of the two punch bodies 10, which is convenient for changing punches to process holes of different diameters. The punches required for a batch of pipes can be changed in advance on the punch fixing seat 6, which facilitates quick punch change processing and improves processing efficiency and processing accuracy.

[0042] I. Positioning, Clamping, and Adaptive Feeding of Photovoltaic Support Pipes

[0043] For standard profiles commonly used in photovoltaic brackets, such as Φ40-Φ80mm round tubes and 40×40mm-80×80mm square tubes, the equipment achieves precise positioning through a combination structure of 21 double clamping bars and 12 limiting rollers.

[0044] Profile cross-section adaptation: The limiting roller 12 in the mounting groove 22 is a combination of an adjustable angle V-shaped roller (suitable for round tubes) and a flat roller (suitable for square tubes). The roller surface is covered with an anti-slip rubber layer (Shore hardness 70A). The contact angle can be adjusted by rotating the mounting shaft of the limiting roller to ensure a tight fit with the surface of the photovoltaic tube and avoid displacement during punching.

[0045] Step feed control: When processing the transverse connecting rods of the solar panel bracket (which need to be punched at equal intervals of 300-1500mm), after the tube is clamped by the limit roller 12, the limit roller group moves linearly by manual pushing or external servo motor driving. With the help of the equipment control system (an encoder can be selected), a step accuracy of ±0.2mm is achieved, which meets the strict standard of hole spacing of photovoltaic bracket (such as the hole spacing tolerance of ±0.5mm in GB / T39055-2020 "General Technical Requirements for Solar Photovoltaic Bracket Systems").

[0046] II. High-efficiency machining technology for multi-specification holes

[0047] For typical hole types in photovoltaic support tubes (Φ8-Φ20mm mounting holes, oblong adjustment holes, etc.), the equipment achieves flexible processing through a punch quick-change system and a flipping mechanism:

[0048] Punch pre-installation design: The upper and lower ends of the punch fixing base 6 can respectively install punch bodies 10 with different hole diameters (such as a Φ12mm round hole punch at the upper end and a Φ16mm waist-shaped punch at the lower end), corresponding to the bolt holes (M10-M16) for connecting the photovoltaic bracket and the column, and the mounting holes for the photovoltaic panel clamps. Before processing, according to the drawing requirements (such as processing 3 different hole diameters for a single pipe), the required punches are fixed in advance to the locking block 11 by the screw 8 (M12×30mm stainless steel material), avoiding the time-consuming problem of frequent machine downtime for mold changing in traditional equipment (the time for a single mold change is reduced from 15 minutes to 30 seconds).

[0049] Flipping and positioning accuracy: When the punch needs to be switched, cylinder 15 drives rack 14 to move (stroke 50mm), which in turn drives gear 13 (module 2, number of teeth 25) to rotate 180°, so that the punch fixing seat 6 can be flipped up and down. The self-aligning bearings (model UC205) at both ends of the rotating rod 5 ensure that the perpendicularity error between the punch axis and the tube surface is ≤0.1° during the flipping process, which meets the industry standard for the perpendicularity of the photovoltaic bracket hole position (≤0.5°) (refer to NB / T10296-2020 "Steel Pipe for Solar Photovoltaic Brackets").

[0050] III. Mechanism for Ensuring the Processing Precision of Photovoltaic Profiles

[0051] Addressing the challenges in processing photovoltaic support tubing (easily deformable aluminum alloy tubing, and controlling burrs during punching of thin-walled steel tubing), the equipment improves processing quality through multiple structural designs:

[0052] Pressure Adaptive System: Cylinder No. 1 3 (stroke 100mm, thrust 5-15kN adjustable) is equipped with a pressure sensor. When processing 6063-T5 aluminum alloy pipes, the punching pressure can be controlled at 8kN±5% to avoid pipe denting due to excessive pressure. When processing Q235B thin-walled steel pipes (wall thickness 2-4mm), the chamfering design of the punch body 10 (15° guide cone angle) and the rigid support of the limiting plate 9 control the punching burr height to below 0.1mm, reducing the need for subsequent deburring processes.

[0053] Balanced clamping force control: When the double-threaded screw 19 (5mm pitch, 6h grade thread accuracy) is manually adjusted in conjunction with the rocker plate 20, the distance between the two clamping bars 21 can be precisely controlled through the dial (0.5mm accuracy) to ensure that the clamping force of the Φ60mm round tube and the 50×50mm square tube is evenly distributed (error ≤5%), avoiding hole position displacement caused by clamping skew (the measured lateral deviation of the hole position is ≤0.3mm, which is better than the industry requirement of ±0.5mm).

[0054] IV. Typical Application Scenarios in the Photovoltaic Industry

[0055] Processing of fixed support beam: When processing 1.5m long Q235B hot-dip galvanized square tubes (40×40×2.5mm), first adjust the spacing of the clamping bars to 40mm using the rocker plate 20, and then fit the limit rollers 12 against both sides of the square tube; start cylinder 3 to complete the punching of Φ10mm mounting holes, with a single punching cycle time of 8 seconds; when processing Φ14mm adjustment holes, flip the punch fixing seat using cylinder 15, and switch without stopping the machine. The processing efficiency of a single tube is 40% higher than that of traditional equipment.

[0056] Tracking bracket shaft tube processing: For the multi-angle punching requirements of aluminum alloy round tube (Φ80×3mm, 6061-T6), the angle adjustment function of the limit roller 12 is used to fix the rotation angle of the tube. The punch flips and processes three sets of Φ18mm through holes evenly distributed around the circumference in sequence. The hole position angle deviation is ≤0.5°, which meets the high-precision assembly requirements of the tracking bracket shaft.

[0057] The aforementioned customized design for the photovoltaic industry effectively solves the pain points of frequent mold changes and unstable precision in the mass production of photovoltaic brackets, which is in line with the trend of high efficiency and intelligent development in new energy equipment manufacturing.

[0058] 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 claimed utility model.
