Description

Technical Field

[0001] This invention relates to the field of bracket forging, and more specifically, to a photovoltaic panel bracket forging apparatus. Background Technology

[0002] Bracket forging is the process of manufacturing brackets with specific shapes, sizes, and properties through forging technology, further improving the strength and toughness of the metal so that it can withstand higher loads.

[0003] Photovoltaic panel brackets, also known as solar photovoltaic (PV) brackets, are crucial structural components used to support and secure photovoltaic modules. In large-scale PV power plants, the large size of the PV panels mounted on these brackets, along with the need to house other equipment, necessitates the use of critical bracket components capable of withstanding significant loads. Die forging is a good method for producing these components; however, die forging molds are expensive. Furthermore, without proper mold protection during forging, excessive pressure from the forging head can easily damage the mold over time. Therefore, this paper proposes a photovoltaic panel bracket forging device. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a photovoltaic panel bracket forging device.

A first flexible hose is fixedly inserted into the bottom of the oil chamber, and the oil chamber communicates with the retention chamber through the first flexible hose. The first one-way valve is used to send the gas in the buffer groove into the oil chamber.

[0008] Furthermore, a second one-way valve is fixedly installed on the other side of the inner wall of the top of the buffer tank. Air in the negative pressure chamber enters the buffer tank through the second one-way valve. A second flexible tube is fixedly inserted at the bottom of the negative pressure chamber, and the negative pressure chamber is connected to the retention chamber through the second flexible tube.

[0009] Furthermore, the bottom of the piston chamber is provided with two sets of sliding columns for sliding sealing, and the bottom of the sleeve is symmetrically provided with two sets of circular grooves. A first sliding rod is provided in one set of the circular grooves for sliding sealing. A first air hole is provided at the bottom of the annular shell. The first air hole connects the negative pressure chamber to the second hose. A second air hole is provided on the first sliding rod. One end of the first sliding rod is located inside the sliding column. A first thrust spring is provided in each set of the circular grooves. One end of the first thrust spring is fixedly connected to the first sliding rod, and the other end of the first thrust spring is fixedly connected to the inner wall of the circular groove.

[0010] Furthermore, another set of the circular grooves is provided with a sliding seal for a second slide rod, the second slide rod having a third air hole, and the bottom of the annular housing having a fourth air hole, the fourth air hole connecting the oil chamber to the first hose, and the third air hole connecting to the fourth air hole when the first thrust spring is in a stationary state.

[0011] Furthermore, the end of the first slide rod near the first thrust spring is a magnetic block, and a set of conductive grooves that cooperate with the magnetic block are also provided at the bottom of the annular shell. A conductive iron block is slidably arranged inside the conductive groove, and a tension spring is also provided inside the conductive groove. One end of the tension spring is fixedly connected to the conductive iron block, and the other end of the tension spring is fixedly connected to the inner wall of the conductive groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) By setting up a forging drive assembly, this application can reduce the excessive forging of the support material by the forging head, which may lead to quality problems in the support material. At the same time, when the forging head impacts the mold body, the support material can buffer the impact force of the forging head on the mold body to a certain extent. If the impact force of the forging head on the support material at different stages is the same, then the thinner the support material, the greater the impact force on the mold body, and the easier it is to be damaged, thus effectively ensuring the service life of the mold body.

[0018] (2) This application uses a second hose, a retention chamber, a negative pressure chamber, a first air hole and a second air hole, and a suction hole to firmly hold the forged support material. At this time, the external control console makes the air pump work to suck out a small part of the gas in the pressurization chamber, so that the forging head moves up slightly and the support material leaks out of the mold. At this time, the support material is fixed and the air pump continues to work to make the forging head move up and reset. At this time, the support material is taken out, which can help to take out the forged support material. It is convenient for the staff to take out the forged support material, effectively saving the demolding time of the support material and improving work efficiency. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8A photovoltaic panel bracket forging device includes a frame 1, a mold body 2 fixedly mounted at the bottom of the frame 1 for holding the bracket raw material, a forging drive assembly 3 fixedly mounted on the frame 1, a forging head 4 mounted at the bottom of the forging drive assembly 3, the forging head 4 being adapted to the mold body 2, and the forging drive assembly 3 being used to realize the forging action of the forging head 4 on the bracket raw material. The forging drive assembly 3 includes an air pump 5 fixedly mounted on the frame 1, and a sleeve 6 fixedly mounted on the frame 1, the sleeve 6 having an internal sliding seal. The sleeve 6 is equipped with a piston body 7. The sleeve 6 is divided into a pressurizing chamber 8 and a piston chamber 9 by the piston body 7. The air pump 5 is connected to the pressurizing chamber 8. The space inside the sleeve 6 above the piston body 7 is the pressurizing chamber 8, and the space inside the sleeve 6 below the piston body 7 is the piston chamber 9. The bottom of the piston body 7 is fixedly connected to a push rod 10. The push rod 10 extends downward to the outside of the piston chamber 9 and is fixedly connected to the forging head 4. The bottom wall of the piston chamber 9 is provided with an air flow hole 11. The air pump 5 inputs the same amount of gas into the pressurizing chamber 8 each time.

[0031] When forging the support material using the equipment, the support material is first placed in the mold body 2. Then, the air pump 5 is activated by the external control console to inject gas into the pressurization chamber 8. After the gas enters the pressurization chamber 8, the gas pushes the piston body 7 downward and discharges the gas in the piston chamber 9 through the flow hole 11. Subsequently, the piston body 7 moves downward along with the push rod 10, thereby achieving the purpose of the forging head 4 hammering the support material. Then, the air pump 5 sucks out the gas from the pressurization chamber 8. At this time, the piston chamber 9 draws air in through the flow hole 11, causing the piston body 7, push rod 10, and forging head 4 to move upwards together. The air pump 5 works repeatedly to achieve the forging effect on the support material. Under the condition that the air pump 5 injects the same volume of gas into the pressurizing chamber 8 each time, a portion of the air pressure is used to push the forging head 4 and push rod 10 to move. Since the thickness of the support material gradually decreases with each forging, the downward distance of push rod 10 and forging head 4 gradually increases, and more air pressure is used to push the forging head 4 to move. The remaining air pressure is used for... The air pressure of the forging support material gradually decreases, resulting in less force exerted on the support material by the forging head 4 during forging. This reduces the risk of over-forging of the support material by the forging head 4, which could lead to quality problems. At the same time, when the forging head 4 impacts the mold body 2, the support material can buffer the impact force of the forging head 4 on the mold body 2 to a certain extent. If the impact force of the forging head 4 on the support material at different stages is the same, then the thinner the support material, the greater the impact force on the mold body 2, and the more easily the mold body 2 will be damaged. This effectively ensures the service life of the mold body 2.

[0032] It should be noted that the top of the air pump 5 is connected to the outside air through a hose, and the external control panel is used to control the start and stop of the air pump 5. Each time the air pump 5 injects air into the pressurization chamber 8, the piston body 7 can move from the top of the sleeve 6 to the bottom of the sleeve 6.

[0033] like Figures 1 to 3 As shown, a retention chamber 12 is provided inside the forging head 4. Multiple suction holes 13 are provided at the bottom of the forging head 4. The suction holes 13 extend upward and communicate with the retention chamber 12. An annular shell 14 is fixedly fitted on the outer surface of the sleeve 6. A through hole 15 is provided at the bottom of the inner wall of the sleeve 6. A buffer groove 16 is provided inside the annular shell 14. The through hole 15 is located at the bottom of the buffer groove 16 and communicates with the buffer groove 16. An oil chamber 17 and a negative pressure chamber 18 that are not interconnected are provided on both sides of the annular shell 14. A first one-way valve 19 is fixedly installed on one side of the top inner wall of the buffer groove 16. A first flexible hose 20 is fixedly inserted at the bottom of the oil chamber 17. The oil chamber 17 communicates with the retention chamber 12 through the first flexible hose 20. The first one-way valve 19 is used to send the gas in the buffer groove 16 into the oil chamber 17.

[0034] When the forging drive assembly 3 starts working, the push rod 10... Figure 2 As shown in the diagram, when the piston moves downward, a small amount of gas in the piston chamber 9 will enter the buffer groove 16 through the through hole 15, and then enter the oil chamber 17 through the first one-way valve 19, thereby increasing the air pressure inside the oil chamber 17. The lubricating oil inside the oil chamber 17 is then sent into the retention chamber 12 through the first hose 20, and then diverted to the suction hole 13 through the retention chamber 12. The lubricating oil is then sprayed from the suction hole 13 onto the support material at the bottom of the forging head 4. Spraying lubricating oil during forging can effectively reduce the forging pressure required for forging the support material. Even if a portion of the air pressure is used for other purposes, the forging head 4 can still achieve the forging effect on the support material.

[0035] like Figure 3 - Figure 8 As shown, a second one-way valve 21 is fixedly installed on the other side of the top inner wall of the buffer tank 16. Air in the negative pressure chamber 18 enters the buffer tank 16 through the second one-way valve 21. A second hose 22 is fixedly inserted into the bottom of the negative pressure chamber 18. The negative pressure chamber 18 is connected to the retention chamber 12 through the second hose 22.

[0036] The bottom of the piston chamber 9 is provided with two sets of sliding columns 23 for sliding sealing. The bottom of the sleeve 6 is provided with two sets of circular grooves 24 symmetrically. One set of circular grooves 24 is provided with a first sliding rod 25 for sliding sealing. The bottom of the annular shell 14 is provided with a first air hole 26, which connects the negative pressure chamber 18 to the second hose 22. The first sliding rod 25 is provided with a second air hole 27. One end of the first sliding rod 25 is located inside the sliding column 23. Each set of circular grooves 24 is provided with a first thrust spring 28. One end of the first thrust spring 28 is fixedly connected to the first sliding rod 25, and the other end of the first thrust spring 28 is fixedly connected to the inner wall of the circular groove 24.

[0037] The size of the first slide rod 25 is larger than the size of the first air hole 26. The first slide rod 25 is separated from the negative pressure chamber 18 inside the slide column 23 and connected to the second hose 22.

[0038] Each set of sliding pillars 23 has an inclined slot 39 inside. The part of the first sliding rod 25 inserted into the sliding pillar 23 is inclined. The inclined slot 39 is used for the insertion of the first sliding rod 25 and the second sliding rod 29.

[0039] Each set of sliding pillars 23 is fitted with a second thrust spring 38 on its outer surface. The top end of the second thrust spring 38 is fixedly connected to the top end of the outer surface of the sliding pillar 23, and the bottom end of the second thrust spring 38 is fixedly connected to the bottom of the piston chamber 9.

[0040] After the equipment has completed the forging operation of the support material, the piston body 7 has moved to the bottom of the piston chamber 9. At this time, the piston body 7 will press down on the sliding column 23, and at the same time, the second thrust spring 38 will contract. As the sliding column 23 moves down, under the action of the inclined groove 39 inside the sliding column 23, the first sliding rod 25 will pass through its inclined side as... Figure 3 As shown, the forging head moves to the right, leaving a small gap for gas to pass through between the first vent 26 and the second vent 27. Under the action of the gas inside the negative pressure chamber 18, the forged support material is firmly sucked in through the second hose 22, the retention chamber 12 and the suction hole 13. At this time, the external control console operates the air pump 5 to suck out a small part of the gas in the pressurization chamber 8, causing the forging head 4 to move up slightly, and the support material is partially exposed from the mold. The support material is then fixed, and the air pump 5 continues to operate to move the forging head 4 back up to its original position. The support material can then be removed, which helps to remove the forged support material, making it easier for workers to remove the forged support material, effectively saving the demolding time of the support material and improving work efficiency.

[0041] After each impact of the forging head 4 on the support material, the piston body 7 moves upward. At this time, the piston chamber 9 will draw in air through the flow hole 11 and the through hole 15. At this time, the gas in the negative pressure chamber 18 will be gradually extracted. As the number of impacts of the forging head 4 gradually increases, the gas content inside the negative pressure chamber 18 becomes less, so as to achieve the purpose of having negative pressure inside the negative pressure chamber 18, which facilitates the subsequent operation of demolding the support material.

[0042] like Figures 2 to 7 As shown, another set of circular grooves 24 is provided with a sliding seal for a second slide rod 29. A third air hole 30 is provided on the second slide rod 29. A fourth air hole 31 is provided at the bottom of the annular housing 14. The fourth air hole 31 connects the oil chamber 17 with the first hose 20. When the first thrust spring 28 is in a stationary state, the third air hole 30 is connected to the fourth air hole 31. The part of the second slide rod 29 inserted into the slide column 23 is inclined.

[0043] In the initial state, the third air hole 30 and the fourth air hole 31 of the second slide bar 29 are connected to each other.

[0044] As the piston body 7 presses down on the sliding rod 23, the sliding rod 23 moves downward, and at the same time, the second sliding rod 29 will move as follows: Figure 3 As shown, the movement to the left gradually disconnects the third air hole 30 and the fourth air hole 31 until the equipment has completed the forging operation of the support material. The equipment then begins to discharge the material from the auxiliary mold body 2. To prevent oil spraying at this time, which would cause the support material to fall, the fourth air hole 31, which is closed by the second slide bar 29, cannot inject lubricating oil into the retention chamber 12 and suction hole 13 through the third air hole 30. At this time, the first hose 20 can be considered closed, which further ensures the vacuum inside the forging head 4 used to suck up the support material when the negative pressure chamber 18 is working, ensuring the suction force of the forging head 4 and ensuring the safety of the auxiliary material discharge of the forging head 4.

[0045] It should be noted that the size of the second slide bar 29 is larger than the size of the fourth air hole 31.

[0046] like Figures 3 to 7 As shown, the end of the first slide bar 25 near the first thrust spring 28 is a magnetic block 32. The bottom of the annular housing 14 is also provided with a set of conductive slide grooves 33 that cooperate with the magnetic block 32. A conductive iron block 34 is slidably arranged inside the conductive slide groove 33. A tension spring 35 is also arranged inside the conductive slide groove 33. One end of the tension spring 35 is fixedly connected to the conductive iron block 34, and the other end of the tension spring 35 is fixedly connected to the inner wall of the conductive slide groove 33. An indicator light 36 is fixedly arranged on the outer surface of the annular housing 14. When the conductive slide groove 33 comes into contact with the conductive iron block 34, the indicator light 36 will light up.

[0047] The inner wall of the conductive groove 33 near the indicator light 36 is an annular conductive plate 37. The annular conductive plate 37 is electrically connected to an external power supply. The annular conductive plate 37, the conductive iron block 34 and the indicator light 36 are electrically connected to each other. The conductive iron block 34 is an iron block with copper wire attached to its surface, and the copper wire is attached perpendicular to the horizontal plane.

[0048] After the forging operation of the support material is completed, at this time, due to the first slide bar 25 as... Figure 3 As shown, the magnetic block 32 moves to the right along with the magnetic block 32 in the circular groove 24. At the same time, the first thrust spring 28 contracts. The magnetic block 32 has now moved to the rightmost end of the circular groove 24. Due to the magnetic force of the magnetic block 32, it will attract the conductive iron block 34, which was originally used to keep the indicator light 36 lit, located in the conductive groove 33. The conductive iron block 34 will then move toward the magnetic block 32. As the conductive iron block 34 leaves the annular conductive plate 37 of the conductive groove 33, the indicator light 36 will stop lighting up, indicating that the forging operation is over and alerting the workers.

[0049] Instructions for use: When forging the support material using the equipment, first place the support material in the mold body 2. Then, operate the air pump 5 via the external control console to inject gas into the pressurizing chamber 8. Once gas enters the pressurizing chamber 8, it pushes the piston body 7 downwards and discharges the gas from the piston chamber 9 through the flow hole 11. The piston body 7 then moves downwards along with the push rod 10, thus achieving the purpose of the forging head 4 hammering the support material. Subsequently, the air pump 5 draws out the gas from the pressurizing chamber 8. At this time, the piston chamber 9 draws in air through the flow hole 11, causing the piston body 7, push rod 10, and forging head 4 to move upwards together. The air pump 5 operates repeatedly to achieve the forging effect on the support material.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
