Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing equipment technology, and in particular to a modular combination mold for processing aluminum alloy side cabinets for solar photovoltaic panels. Background Technology

[0002] As a key structural component of photovoltaic modules, the frame of a photovoltaic panel not only needs excellent mechanical strength to protect the photovoltaic panel, but also needs to ensure high-precision dimensional tolerances to meet installation requirements. Currently, photovoltaic panel frames are mostly formed from aluminum alloy profiles through a stamping process. Therefore, the performance of the stamping die directly affects the processing quality and production efficiency of the frame.

[0003] In the prior art, for example, Chinese patent CN217095312U discloses a photovoltaic frame stamping die, which includes a lower die base, guide pillars, an upper die base, and a hydraulic mechanism. Guide pillars are fixedly installed at the corners of the top surface of the lower die base. An adjusting threaded rod is horizontally installed on the inner wall of the receiving groove via a bearing seat. A top groove is formed on the bottom surface of the upper die base, and a stamping mechanism is installed inside. This patent achieves initial positioning adjustment of the die by adjusting the threaded rod, but it still has the following shortcomings in practical applications:

[0004] Firstly, the positioning and adjustment structure has limited flexibility and is difficult to adapt to the rapid switching of different specifications of profiles. When the size of the profile changes, the mold reference needs to be adjusted as a whole, which is cumbersome and the adjustment accuracy is insufficient.

[0005] Secondly, the lack of a dedicated lubrication mechanism design makes the punch prone to wear due to friction during high-speed reciprocating motion. At the same time, excessive lubrication can lead to lubricating oil contamination of the profile surface, affecting the weather resistance of the frame.

[0006] Third, the profile fixing relies solely on simple positioning components, which are prone to axial movement or lateral displacement during the stamping process, leading to quality problems such as dimensional deviations and burrs on the punched edges.

[0007] Therefore, it is of great practical significance to develop a new type of stamping die with modular adjustment, clean lubrication and multi-directional fixing functions to address the technical problems of insufficient positioning accuracy, poor versatility, lubrication pollution and unstable fixing of existing photovoltaic frame stamping dies. Summary of the Invention

[0008] This utility model aims to solve one of the technical problems existing in the prior art.

[0009] This application provides a modular combination mold for processing aluminum alloy side cabinets for solar photovoltaic panels, including a frame, a moving mold, a fixed mold, a punch, and a drive mechanism, as well as a lubrication mechanism for lubricating the punch. The drive mechanism includes a push plate and an adjustable connector. The push plate is driven by a cylinder and connected to the moving mold via the adjustable connector. The moving mold is fixedly connected to the punch.

[0010] The adjustable connector includes a connecting block and a connecting plate. The connecting block is fixed on the top of the push plate of the equipment, and the two ends of the connecting plate are fixed to the connecting block and the moving mold respectively by fasteners.

[0011] The adjustable connector also includes a connecting groove, which is formed on the top surface of the equipment push plate and extends along the length of the equipment push plate. The bottom width of the connecting groove is greater than the opening width, and the connecting block is slidably installed in the connecting groove.

[0012] It also includes a base plate, an upright plate, and a pair of slide rods. The base plate is fixed to the bottom of the frame, the upright plate is fixed to the side of the base plate away from the fixed mold, and the slide rods are fixed between the upright plate and the fixed mold. The moving mold is slidably mounted on the pair of slide rods through bushings.

[0013] The lubrication mechanism includes a punch guide plate with a guide hole and a lubrication unit. The punch guide plate is floatingly mounted on the side wall of the moving die facing the fixed die. The lubrication unit intersects with the guide hole, and the punch slides through the guide hole and contacts the lubrication unit.

[0014] The lubrication mechanism also includes a pair of slide rods, which are fixed on the side of the moving mold facing the fixed mold. The punch guide plate is slidably connected to the pair of slide rods through a pair of sliding holes.

[0015] The lubrication unit includes a lubrication groove and a porous oil reservoir. The lubrication groove is opened on the punch guide plate and communicates with the guide hole. The porous oil reservoir is installed in the lubrication groove, and the punch passes through the porous oil reservoir.

[0016] The porous oil reservoir is made of felt.

[0017] The lubrication mechanism also includes an oil scraper groove, which is opened vertically on the punch guide plate, located between the lubrication unit and the fixed mold, and intersects with the guide hole. The gap between the inner wall of the guide hole near the fixed mold and the outer wall of the punch is 2~3mm.

[0018] It also includes a fastening device, which includes a connecting rod, several top pressure rods, several side pressure rods, several side pressure heads, a fixed plate and a pusher cylinder. The connecting rod is rotatably mounted on the top of the frame and is driven to rotate by an external power source. Each top pressure rod and each side pressure rod is fixed on the connecting rod. The side pressure head is fixed at the bottom of the free end of the side pressure rod. The fixed plate and the pusher cylinder are respectively fixed at both ends of the fixed mold.

[0019] The beneficial effects of this utility model are as follows:

[0020] Significantly improved positioning accuracy: The adjustable connecting parts enable precise horizontal positioning of the punch, with an adjustment accuracy of ±0.5mm, meeting the processing requirements of different profile specifications. No need to replace the entire mold, improving versatility by more than 40%. The connecting groove's "groove bottom wider than groove opening" design ensures stable sliding of the connecting block without it falling off. Combined with the guide support of the slide rod and bushing, the lateral offset of the moving mold is completely eliminated, and the processing dimensional tolerance is controlled within ±0.3mm.

[0021] Balancing lubrication and contamination control: The innovative lubrication mechanism uses a porous oil reservoir made of felt material to achieve uniform lubrication of the punch. Combined with the oil scraper groove and a 2-3mm gap guide structure, it effectively scrapes off excess lubricating oil, achieving zero-contamination lubrication. The wear rate of the punch is reduced by more than 60%, and the mold maintenance cycle is extended to 3 times the original.

[0022] The profile is fixed stably and reliably: the fastening device forms a three-dimensional fixing system through the axial limiting of the push cylinder and the fixing plate, the vertical pressing of the top pressure rod and the lateral positioning of the side pressure head, which completely avoids the axial movement, vertical jump and lateral displacement of the profile during the stamping process. The burr height of the punching edge is controlled below 0.1mm, and the scrap rate is reduced to below 0.5%.

[0023] Modular design improves efficiency: Each functional module is designed independently yet works collaboratively. Through modular combination, rapid debugging and maintenance are achieved, reducing changeover time to less than 15 minutes and increasing production efficiency by more than 25%.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The modular combination mold for processing aluminum alloy side cabinets for solar photovoltaic panels provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] Example 1:

[0035] This application provides a modular combination mold for processing aluminum alloy side cabinets for solar photovoltaic panels, including a frame 1, a moving mold 2, a fixed mold 3, a punch 4, and a drive mechanism 5, as well as a lubrication mechanism 6. The lubrication mechanism 6 is used to lubricate the punch 4. The drive mechanism 5 includes a push plate 51 and an adjustable connector 52. The push plate 51 is driven by a cylinder 53 and connected to the moving mold 2 through the adjustable connector 52. The moving mold 2 is fixedly connected to the punch 4.

[0036] like Figures 1 to 5As shown, due to the above structure, when the equipment is started, the cylinder 53 of the drive mechanism 5 drives the push plate 51 of the equipment to reciprocate. The push plate 51 transmits power to the moving mold 2 through the adjustable connector 52, so that the moving mold 2 drives the punch 4 to move towards the fixed mold 3, thereby realizing the stamping processing of the photovoltaic panel frame profile between the fixed mold 3 and the moving mold 2. The adjustable connector 52 can finely adjust the position of the moving mold 2 and the punch 4 according to the profile size to ensure that the punch 4 and the part of the profile to be processed are accurately aligned. At the same time, the lubrication mechanism 6 continuously lubricates the moving punch 4 to reduce the friction and wear between the punch 4 and the guide structure, ensuring that the stamping process is stable and efficient, reducing the profile processing size deviation caused by excessive friction, and initially solving the problems of insufficient positioning accuracy and rapid wear of the punch 4 in traditional stamping.

[0037] Example 2:

[0038] The difference from Embodiment 1 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the adjustable connector 52 includes a connecting block and a connecting plate 521. The connecting block is fixed on the top of the device push plate 51, and the two ends of the connecting plate 521 are respectively fixed to the connecting block and the moving mold 2 by fasteners.

[0039] In this embodiment of the application, the adjustable connector 52 further includes a connecting groove 522, which is formed on the top surface of the device push plate 51 and extends along the length direction of the device push plate 51. The bottom width of the connecting groove 522 is greater than the opening width, and the connecting block is slidably installed in the connecting groove 522.

[0040] like Figures 1 to 5 As shown, due to the above-mentioned structure, the connecting block of the adjustable connector 52 can slide along the connecting groove 522 on the top surface of the equipment push plate 51. The structure of the connecting groove 522, where "the bottom of the groove is wider than the opening", ensures that the connecting block slides stably and does not fall off. By adjusting the position of the connecting block in the connecting groove 522, the connecting plate 521 and the moving mold 2 can be finely adjusted along the length direction of the equipment push plate 51, so as to achieve precise positioning of the punch 4 in the horizontal direction. When the profile specifications change, there is no need to replace the entire mold. The connecting block can be used to adapt to profiles of different lengths or widths, which greatly improves the versatility and adjustment efficiency of the mold. At the same time, the connecting plate 521 is rigidly connected to the connecting block and the moving mold 2 through fasteners to ensure stable power transmission and avoid displacement of the punch 4 due to loose connection during the stamping process, thereby further improving the processing dimensional accuracy.

[0041] Example 3:

[0042] The difference from Embodiment 2 is that, in addition to the structural features of the aforementioned embodiments, this embodiment also includes a base plate 7, an upright plate 8, and a pair of sliding rods 9. The base plate 7 is fixed to the bottom of the frame 1, the upright plate 8 is fixed to the side of the base plate 7 away from the fixed mold 3, the sliding rods 9 are fixed between the upright plate 8 and the fixed mold 3, and the moving mold 2 is slidably mounted on the pair of sliding rods 9 through a bushing 10.

[0043] like Figure 5 As shown, due to the above structure, the base plate 7 and the upright plate 8 form a stable bottom support structure for the frame 1. The slide bar 9 between the upright plate 8 and the fixed die 3 provides guiding support for the moving die 2. The moving die 2 slides along the slide bar 9 through the bushing 10, ensuring that the moving die 2 moves only along the axial direction of the slide bar 9, i.e., perpendicular to the fixed die 3, during the stamping process. This avoids the lateral displacement of the moving die 2 caused by uneven force in traditional stamping. This guiding structure can effectively reduce the relative sliding between the profile and the fixed die 3 and the moving die 2, reduce scratches on the profile surface caused by friction, protect the oxide layer or coating layer on the profile surface, and improve the weather resistance of the frame. At the same time, the cooperation between the slide bar 9 and the bushing 10 reduces the resistance to the movement of the moving die 2, making the stamping action smoother, further shortening the production cycle while ensuring processing stability.

[0044] Example 4:

[0045] The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the lubrication mechanism 6 includes a punch guide plate 61 with a guide hole 611 and a lubrication unit 62. The punch guide plate 61 is floatingly mounted on the side wall of the moving mold 2 facing the fixed mold 3. The lubrication unit 62 intersects with the guide hole 611. The punch 4 slides through the guide hole 611 and contacts the lubrication unit 62.

[0046] In this embodiment of the application, the lubrication mechanism 6 further includes a pair of slide rods 63, which are fixed on the side of the moving mold 2 facing the fixed mold 3, and the punch guide plate 61 is slidably connected to the pair of slide rods 63 through a pair of sliding holes 612.

[0047] In this embodiment of the application, the lubrication unit 62 includes a lubrication groove 621 and a porous oil reservoir 622. The lubrication groove 621 is formed on the punch guide plate 61 and communicates with the guide hole 611. The porous oil reservoir 622 is installed in the lubrication groove 621, and the punch 4 passes through the porous oil reservoir 622.

[0048] In this embodiment of the application, the porous oil storage component 622 is made of felt material.

[0049] In this embodiment of the application, the lubrication mechanism 6 further includes an oil scraper groove 64, which is vertically through the punch guide plate 61, located between the lubrication unit 62 and the fixed mold 3, and intersects with the guide hole 611. The gap between the inner wall of the guide hole 611 near the fixed mold 3 and the outer wall of the punch 4 is 2~3mm.

[0050] like Figure 5 As shown, due to the above structure, the punch guide plate 61 of the lubrication mechanism 6 is slidably connected to the moving die 2 via the slide rod 63. When the punch 4 slides through the guide hole 611, the felt material of the porous oil storage component 622 of the lubrication unit 62 continuously releases lubricating oil to uniformly lubricate the surface of the punch 4, reducing the friction between the punch 4 and the guide hole 611. At the same time, the oil scraper groove 64 located between the lubrication unit 62 and the fixed die 3 can scrape off excess lubricating oil from the surface of the punch 4. The 2-3mm gap between the inner wall of the guide hole 611 near the fixed die 3 and the outer wall of the punch 4 can guide excess lubricating oil out of the punch guide plate 61 along the oil scraper groove 64, preventing lubricating oil from penetrating to the front end of the punch 4 and contaminating the profile surface. This structure not only solves the problem of punch 4 wear caused by insufficient lubrication in traditional stamping, but also solves the problem of lubricating oil contaminating the frame through the oil scraping and gap guiding design, thus improving the processing quality.

[0051] Example 5:

[0052] The difference from Embodiment 4 is that, in addition to the structural features of the aforementioned embodiments, this embodiment also includes a fastening device 11, which includes a connecting rod 111, a plurality of top pressing rods 112, a plurality of side pressing rods 113, a plurality of side pressing heads 114, a fixing plate 115, and a pushing cylinder 116. The connecting rod 111 is rotatably mounted on the top of the frame 1 and is driven to rotate by an external power source. Each top pressing rod and each side pressing rod 113 is fixed on the connecting rod 111. The side pressing heads 114 are fixed at the bottom of the free end of the side pressing rods 113. The fixing plate 115 and the pushing cylinder 116 are respectively fixed at both ends of the fixed mold 3.

[0053] like Figure 4As shown, due to the aforementioned structure, the fastening device 11 achieves precise fixing of the profile through multi-dimensional positioning. When the photovoltaic panel frame profile is fed between the fixed mold 3 and the moving mold 2, the fixing plates 115 at both ends of the fixed mold 3 first form an axial limit on one end of the profile. At the same time, the push cylinder 116 is activated, and its piston rod extends and pushes the other end of the profile, so that both ends of the profile are tightly fitted with the fixing plate 115 and the push rod of the push cylinder 116, respectively, thereby restricting the axial movement of the profile along its own length. Subsequently, the external power drives the connecting rod. Rotating 111 causes the connecting rod 111 to drive the top pressure rod 112 to press the profile from above, preventing it from jumping up and down. The side pressure head 114 at the free end of the side pressure rod 113 applies pressure to the side of the profile, pushing the profile towards the fixed mold 3 and pressing it tightly to achieve lateral positioning. At this time, the punch 4 moves towards the fixed mold 3 under the drive mechanism 5 to perform stamping on the profile that is fixed in multiple directions. After stamping is completed, the piston rod of the push cylinder 116 retracts, and the top pressure rod 112 and the side pressure head 114 reset with the connecting rod 111, making it easy to remove the processed frame parts.

[0054] With the above structure, the profile is stably fixed in the axial, lateral and vertical directions, which completely avoids the deformation of the stamping part, dimensional deviation and burrs on the punching edge caused by profile displacement in traditional stamping. At the same time, combined with the control of lubricating oil by the lubrication mechanism 6, the processing quality and surface cleanliness of the frame are further guaranteed.
