Description

Technical Field

[0001] This invention relates to the field of photovoltaic clip stamping technology, specifically to a lightweight photovoltaic clip short frame stamping device and its stamping method. Background Technology

[0002] The lightweight photovoltaic clip short frame stamping device is a stamping forming equipment specially designed for the manufacture of photovoltaic module frames. Its core objective is to realize the manufacturing of the frame structure, so that the photovoltaic clip short frame is folded into a right angle.

[0003] In existing technologies, the stamping of the short frame of lightweight photovoltaic clips can easily injure workers, posing a safety hazard and affecting their safety.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN224087749U) discloses a bracket stamping forming device, including a stamping table. A support column and a foot column are fixedly connected to the top surface of the stamping table. A lower die base is bolted to the top of the foot column. A top plate is fixedly connected to the top of the support column. A connecting plate is fixedly connected to the lower surface of the top plate. A T-shaped rack is bolted to the bottom end of the connecting plate. A gear is meshed with the T-shaped rack. A shaft is fixedly connected inside the gear. By placing the sheet metal on the lower die, the hydraulic cylinder is activated to drive the upper die base downward to achieve die closing and stamping. At the same time, the downward movement of the upper die base drives the fixed block, shaft, and gear to move. Under the meshing of the T-shaped rack, the gear rotates, driving the shaft and stop rod to rotate. When the stop rod rotates, it sweeps the area between the upper and lower dies. If a person's hand is in this dangerous area, it will be touched by the flexible plastic material stop rod, which will promptly remind the operator to remove their hand and effectively avoid safety accidents.

[0005] To overcome the above shortcomings, a prior art Chinese patent (publication number CN206083607U) discloses an aluminum plate stamping device, including a machine base, a stamping pressing device, a lower die, and an upper die. The machine base has an installation groove, and the lower die is installed in the installation groove. The lower die has a groove, and a support plate is installed in the groove. The support plate is connected to the bottom of the groove by several springs. Several positioning posts are provided on the top of the lower die wall. The stamping pressing device is located above the lower die, and the upper die is installed at the bottom of the stamping pressing device. The lower half of the upper die is a forming punch that mates with the groove. The upper die has a first positioning hole that mates with the positioning posts, and the stamping pressing device has a second positioning hole that mates with the positioning posts. By installing the lower die in the installation groove and the upper die at the bottom of the stamping pressing device, the stamping device can replace the lower die and upper die as needed, giving the stamping device excellent adaptability.

[0006] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, during the stamping of the short frame of the lightweight photovoltaic buckle, the instantaneous deformation can easily cause the material to generate high temperatures. When the hot workpiece is manually removed by the staff, it can easily cause burns. The operation of removing and cooling the workpiece after stamping is also inconvenient. Summary of the Invention

[0007] The purpose of this invention is to provide a lightweight photovoltaic buckle short frame stamping device and its stamping method, in order to solve the problems mentioned in the background art, where instantaneous deformation during the stamping of lightweight photovoltaic buckle short frames easily leads to high temperatures in the material, and the high-temperature workpiece is prone to burns when manually removed by workers, and the operation of removing and cooling the workpiece after stamping is inconvenient.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a lightweight photovoltaic clip short frame stamping device, comprising a machine base and a machine top mounted on the upper end of the machine base, wherein hydraulic rods are mounted at both ends of the machine base, and the upper output ends of the hydraulic rods are connected to both sides of the machine top; a lower mold is mounted on the upper end of the machine base, and a lower mold is fixedly mounted on the lower end of the machine top; a rear support plate is fixedly mounted on the rear end of the machine base, and a self-discharging mechanism is provided on the upper end of the rear support plate, which removes the lightweight photovoltaic clip short frame from the upper end of the lower mold; an auxiliary cooling mechanism is provided inside the lower mold, which improves the cooling efficiency of the lightweight photovoltaic clip short frame after stamping.

[0009] Furthermore, the self-discharging mechanism is provided with a vertical plate, and the lower end of the vertical plate is fixedly installed on the upper end of the rear support plate, and an ejector block is installed through the interior of the vertical plate.

[0010] Furthermore, the shape of the ejector block is consistent with the groove of the lower mold, and a connecting plate is fixedly installed above the rear end of the ejector block. A traction rope is connected to the surface of the connecting plate, and the middle end of the traction rope passes through the vertical plate. A guide wheel is fitted to the middle end of the traction rope, and the upper end of the traction rope is fixedly installed at the lower end of the upper mold.

[0011] Furthermore, sliding plates are fixedly installed on both sides of the rear end of the ejector block, and guide rods are installed through the interior of the sliding plates, with the front and rear ends of the guide rods fixedly installed between the rear support plate and the upright plate.

[0012] Furthermore, a return spring is sleeved on the surface of the guide rod, and the rear end of the return spring is fixedly installed on the rear surface of the rear support plate, while the front end of the return spring is fixedly installed on the rear end of the slide plate.

[0013] Furthermore, an air pump is fixedly installed at the front end of the upright plate, and the output end of the air pump is aligned with the middle of the lower mold.

[0014] Furthermore, the auxiliary cooling mechanism is provided with a fixing block, which is fixedly installed on the inner wall of the lower mold. A cylindrical plate is provided inside the fixing block, and sliding rods are installed on both sides of the cylindrical plate. The lower end of the sliding rods passes through the fixing block.

[0015] Furthermore, the lower end of the cylindrical plate is spherical, and an adhesive plate is fixedly installed on the upper end of the cylindrical plate, with the upper end of the adhesive plate adhering to the inclined surface of the lower mold.

[0016] Furthermore, auxiliary plates are fixedly installed on both sides of the ejector block, and the ends of the auxiliary plates penetrate the lower mold. The front end of the auxiliary plates is inclined, and the auxiliary plates correspond to the bottom sphere of the cylindrical plate. An air inlet is provided at the rear end of the lower mold.

[0017] Furthermore, a stamping method for a lightweight photovoltaic clip short frame stamping device also includes the following specific steps: S1: After the lightweight photovoltaic buckle short frame material is stamped, the machine top moves to the initial position and then rises again through the hydraulic rod. This causes the machine top to pull the traction rope. After the traction rope is pulled, it passes through the guide wheel through the vertical plate and pulls the connecting plate. The lower end of the vertical plate is installed on the upper end of the rear support plate. After the connecting plate is pulled, the slide plates on both sides of the ejection block move along the guide rod, so that the ejection block is aligned with the groove position of the lower mold and ejects the lightweight photovoltaic buckle short frame. Conversely, when the machine top descends and releases the traction rope, the ejection block is reset by the reset spring on the guide rod, achieving the effect of convenient material handling and convenient material discharge. There is no need for manual contact with the workpiece, the operation is simple, and the risk of being burned by high-temperature workpieces is reduced. S2: As the lightweight photovoltaic buckle short frame material is stamped, the air pumps on both sides of the upright plate are started to start the air extraction and blow air into the groove of the lower mold to cool down the lightweight photovoltaic buckle short frame material after stamping. This can help cool down the lightweight photovoltaic buckle short frame workpiece, accelerate cooling, and reduce the risk of workers being burned. S3: The auxiliary plate follows the movement of the ejector block and passes through the interior of the lower mold. As the auxiliary plate penetrates the lower mold, its front end is tilted, which can squeeze the ball at the bottom of the cylindrical plate. With the ball in place, the contact position at the bottom of the cylindrical plate moves upward due to the tilt of the front end of the auxiliary plate. Slide rods are set on both sides of the cylindrical plate to guide the upper end of the cylindrical plate to drive the bonding plate to rise. The air pump can cool the side of the lightweight photovoltaic buckle short frame workpiece while blowing air through the air inlet at the rear end of the lower mold and blowing it out from the gap between the bonding plate and the lower mold. This allows the cooling air to act not only on the side of the workpiece but also on the bottom of the workpiece, further improving the cooling effect and making the cooling more uniform and effective.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. After the machine top moves to the initial position, it is driven to rise again by the hydraulic rod, which in turn drives the traction rope. After the traction rope is tightened, it passes through the vertical plate guided by the guide wheel, and then pulls the connecting plate. The lower end of the vertical plate is fixed to the upper end of the rear support plate. When the connecting plate is pulled, the slide plates on both sides of the ejection block slide along the guide rod, so that the ejection block is aligned with the groove of the lower mold, and the lightweight photovoltaic buckle short frame is ejected. Conversely, when the machine top descends and the traction rope loosens, the reset spring on the guide rod pulls the ejection block to reset, realizing convenient material removal. The whole process does not require manual contact with the workpiece, the operation is simple, and it effectively reduces the risk of burns caused by high-temperature workpieces.

[0019] 2. During the stamping process of the lightweight photovoltaic buckle short frame material, the air pumps on both sides of the upright plate are started. By drawing air and blowing air into the groove of the lower mold, the stamped workpiece is cooled down. This design helps to accelerate cooling and reduce the risk of workers being burned.

[0020] 3. When the bonding plate rises, it pushes the workpiece in the groove of the lower mold upwards a certain distance. At the same time, during the cooling of the side of the workpiece, the air blown out by the air pump can be blown out from the gap between the bonding plate and the lower mold through the air inlet at the rear end of the lower mold. In this way, the cooling airflow can not only act on the side of the workpiece, but also reach the bottom of the workpiece, improving the overall cooling effect and having a better cooling effect. Furthermore, during the stamping process, when the raw materials are forming the short frame of the lightweight photovoltaic buckle, metal chips are easily generated due to surface rust or coating. If the chips remain on the lower die, it will cause inconvenience to subsequent stamping and may damage the workpiece. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-5The technical solution shown is a lightweight photovoltaic clip short frame stamping device. To solve the problem of high temperature after stamping and inconvenience for workers to remove it, the device discloses: a machine base 1 and a machine top 3 installed on the upper end of the machine base 1. Hydraulic rods 2 are installed at both ends of the machine base 1, and the upper output ends of the hydraulic rods 2 are connected to the two sides of the machine top 3. A lower mold 4 is installed on the upper end of the machine base 1, and the lower mold 4 is fixedly installed on the lower end of the machine top 3. A rear support plate 6 is fixedly installed at the rear end of the machine base 1, and a self-discharging mechanism is provided on the upper end of the rear support plate 6. The self-discharging mechanism removes the lightweight photovoltaic clip short frame from the upper end of the lower mold 4. The self-discharging mechanism is provided with a vertical plate 7, and the lower end of the vertical plate 7 is fixedly installed on the upper end of the rear support plate 6. An ejector block is installed through the interior of the vertical plate 7. 8. The shape of the ejector block 8 is consistent with the groove of the lower mold 4. A connecting plate 9 is fixedly installed above the rear end of the ejector block 8. A traction rope 10 is connected to the surface of the connecting plate 9. The middle end of the traction rope 10 passes through the vertical plate 7. A guide wheel is attached to the middle end of the traction rope 10. The upper end of the traction rope 10 is fixedly installed at the lower end of the upper mold 5. Slide plates 11 are fixedly installed on both sides of the rear end of the ejector block 8. A guide rod 12 is installed through the interior of the slide plate 11. The front and rear ends of the guide rod 12 are fixedly installed between the rear support plate 6 and the vertical plate 7. A return spring 13 is sleeved on the surface of the guide rod 12. The rear end of the return spring 13 is fixedly installed on the rear surface of the rear support plate 6. The front end of the return spring 13 is fixedly installed on the rear end of the slide plate 11.

[0034] The material plate for making the lightweight photovoltaic clip short frame is placed on the lower mold 4 of the machine base 1. During production, the hydraulic rods 2 on both sides of the machine base 1 are activated. The hydraulic rods 2 control the height adjustment of the upper mold 5 on the machine top 3. The upper mold 5 is aligned with the material on the lower mold 4 for stamping, thus realizing the stamping work. After the lightweight photovoltaic clip short frame material is stamped, the machine top 3 moves to the initial position and is raised again by the hydraulic rods 2. This causes the machine top 3 to pull the traction rope 10. After the traction rope 10 is pulled, it moves through the guide wheel... After the guide passes through the upright plate 7, it pulls the connecting plate 9. The lower end of the upright plate 7 is installed on the upper end of the rear support plate 6. After the connecting plate 9 is pulled, the sliding plates 11 on both sides of the ejector block 8 move along the guide rod 12, so that the ejector block 8 is aligned with the groove position of the lower mold 4 and ejects the lightweight photovoltaic buckle short frame. Conversely, when the top of the machine 3 descends and releases the traction rope 10, the ejector block 8 is pulled back to its original position by the reset spring 13 on the guide rod 12, which achieves the effect of convenient material handling and convenient material discharge. There is no need for manual contact with the workpiece, the operation is simple, and the risk of being burned by the high temperature workpiece is reduced.

[0035] Example 2: Figures 1-7The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of long workpiece cooling time: an air pump 14 is fixedly installed at the front end of the upright plate 7, and the output end of the air pump 14 is aligned with the middle end of the lower mold 4.

[0036] As the lightweight photovoltaic buckle short frame material is stamped, the air pumps 14 on both sides of the upright plate 7 are activated to blow air into the groove of the lower mold 4, thereby cooling the lightweight photovoltaic buckle short frame material after stamping. This helps to cool down the lightweight photovoltaic buckle short frame workpiece, accelerates cooling, and reduces the risk of workers being burned.

[0037] Example 3: Figures 1-10 The technical solution shown, based on Embodiment 2, discloses the following to address the problem of insufficient cooling effect during workpiece cooling: An auxiliary cooling mechanism is provided inside the lower mold 4, which improves the cooling efficiency after stamping the short frame of the lightweight photovoltaic buckle. The auxiliary cooling mechanism includes a fixing block 16, which is fixedly installed on the inner wall of the lower mold 4. A cylindrical plate 17 is provided inside the fixing block 16, and sliding rods 19 are installed on both sides of the cylindrical plate 17. The lower end of the sliding rods 19 passes through the fixing block 16. The lower end of the cylindrical plate 17 is spherical, and an adhesive plate 18 is fixedly installed on the upper end of the cylindrical plate 17. The upper end of the adhesive plate 18 adheres to the inclined surface of the lower mold 4. Auxiliary plates 15 are fixedly installed on both sides of the ejector block 8, and the ends of the auxiliary plates 15 pass through the lower mold 4. The front end of the auxiliary plates 15 is inclined, and the auxiliary plates 15 correspond to the bottom sphere of the cylindrical plate 17. An air inlet 20 is provided at the rear end of the lower mold 4.

[0038] As the ejector block 8 moves back and forth, it ejects the workpiece from the lower mold 4. Auxiliary plates 15 are provided on both sides of the ejector block 8. These auxiliary plates 15 follow the movement of the ejector block 8 and pass through the interior of the lower mold 4. With the auxiliary plates 15 penetrating the lower mold 4, their front ends are inclined, allowing them to press the spheres at the bottom of the cylindrical plate 17. The placement of these spheres causes the contact position at the bottom of the cylindrical plate 17 to shift upwards due to the inclined front ends of the auxiliary plates 15. Slide rods 19 are provided on both sides of the cylindrical plate 17, with their surfaces penetrating the fixing block 16. The slide rods 19 guide the cylindrical plate 17, and the upper end of the guide cylindrical plate 17 causes the bonding plate 18 to rise. The rise of the bonding plate 18 causes the groove portion of the lower mold 4 to be pushed by the bonding plate 18. The workpiece moves upward a certain distance. With the air pump 14 in place, the air pump 14 can cool the side of the lightweight photovoltaic buckle short frame workpiece. At the same time, the air blown out by the air pump 14 passes through the air inlet 20 at the rear end of the lower mold 4 and blows out from the gap between the bonding plate 18 and the lower mold 4. This allows the cooling air to act not only on the side of the workpiece but also on the bottom of the workpiece, further improving the cooling effect and making the cooling more uniform. At the same time, as the stamping proceeds, the stamping of the raw material into the lightweight photovoltaic buckle short frame is prone to metal debris due to surface rust or coating. The metal debris remaining on the lower mold 4 makes subsequent stamping of the lightweight photovoltaic buckle short frame inconvenient and easily causes damage to the workpiece.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
