Description

Technical Field

[0001] The present invention relates to the field of bracket forging, and more specifically, to a forging device for a photovoltaic panel bracket. Background Art

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

[0003] A photovoltaic panel bracket, also known as a solar photovoltaic bracket, is an important structural component for supporting and fixing photovoltaic modules. In large-scale photovoltaic power stations, since the photovoltaic panels placed on the photovoltaic panel brackets are relatively large in size, and other equipment also needs to be installed on the photovoltaic panel brackets, this means that key bracket components capable of withstanding large loads are required. Die forging is a good way to produce such components, but the cost of die forging molds is relatively high. When forging brackets, if no protective measures are taken for the molds, when the pressure of the forging head is too large during forging, over time, it is very easy to cause damage to the molds. For this reason, a forging device for a photovoltaic panel bracket is proposed. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a forging device for a photovoltaic panel bracket.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A forging device for a photovoltaic panel bracket includes a frame body. A mold main body is fixedly arranged at the bottom of the frame body, and the mold main body is used for placing bracket raw materials. A forging driving assembly is fixedly arranged on the frame body. A forging head is arranged at the bottom of the forging driving assembly, and the forging head is adapted to the mold main body. The forging driving assembly is used to realize the forging action of the forging head on the bracket raw materials. The forging driving assembly includes an air pump fixedly arranged on the frame body. A sleeve is also fixedly installed on the frame body. A piston main body is slidably and sealingly arranged inside the sleeve. The inside of the sleeve is divided into a pressurizing chamber and a piston chamber by the piston main body. The air pump is communicated with the pressurizing chamber. The space above the piston main body inside the sleeve is the pressurizing chamber, and the space below the piston main body inside the sleeve is the piston chamber. A push rod is fixedly connected to the bottom of the piston chamber, and the push rod extends downward outside the piston chamber and is fixedly connected to the forging head.

[0007] Furthermore, flow holes for communicating with air are formed in the bottom wall of the piston chamber. The amount of gas input into the pressurizing chamber by the air pump each time is the same. A retention chamber is formed inside the forging head. Multiple suction holes are formed in the bottom of the forging head. The suction holes extend upward and communicate with the retention chamber. An annular housing is fixedly sleeved on the outer surface of the sleeve. A through hole is formed in the bottom of the inner wall of the sleeve. A buffer groove is formed in the annular housing. The through hole is located at the bottom of the buffer groove and communicates with the buffer groove. Oil chambers and negative pressure chambers that do not communicate with each other are respectively formed on both sides of the annular housing. A first one-way valve is fixedly arranged on one side of the inner wall of the top of the buffer groove. A first hose is fixedly inserted into the bottom of the oil chamber. The oil chamber communicates with the retention chamber through the first 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 arranged on the other side of the inner wall of the top of the buffer groove. The air in the negative pressure chamber enters the buffer groove through the second one-way valve. A second hose is fixedly inserted into the bottom of the negative pressure chamber. The negative pressure chamber communicates with the retention chamber through the second hose.

[0009] Furthermore, two sliding columns are slidably and sealingly arranged at the bottom of the piston chamber. Two circular sliding grooves are symmetrically formed in the bottom of the sleeve. A first sliding rod is slidably and sealingly arranged in one of the circular sliding grooves. A first air hole is formed in the bottom of the annular housing. The first air hole communicates the negative pressure chamber with the second hose. A second air hole is formed in the first sliding rod. One end of the first sliding rod is located inside the sliding column. A first thrust spring is arranged in each of the circular sliding 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 sliding groove.

[0010] Furthermore, a second sliding rod is slidably and sealingly arranged in the other circular sliding groove. A third air hole is formed in the second sliding rod. A fourth air hole is formed in the bottom of the annular housing. The fourth air hole communicates the oil chamber with the first hose. The third air hole communicates with the fourth air hole when the first thrust spring is in a static state.

[0011] Furthermore, one end of the first sliding rod close to the first thrust spring is a magnetic block. A conductive sliding groove for cooperating with the magnetic block is further formed in the bottom of the annular housing. A conductive iron block is slidably arranged inside the conductive sliding groove. A tension spring is further arranged inside the conductive sliding 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 sliding groove. A warning lamp is fixedly arranged on the outer surface of the annular housing. The warning lamp will be lit after the conductive sliding groove comes into contact with the conductive iron block.

[0012] Further, the inner wall of one end of the conductive chute close to the warning light is an annular conductive plate, which is electrically connected to an external power supply. The annular conductive plate, the conductive iron block and the warning light are electrically connected to each other. The conductive iron block is an iron block with copper wires attached to its surface, and the copper wires are attached perpendicular to the horizontal plane.

[0013] Further, when the second sliding rod is in the initial state, the third air hole and the fourth air hole are communicated with each other. A second thrust spring is sleeved on the outer surface of each sliding column. The top end of the second thrust spring is fixedly connected to the top end of the outer surface of the sliding column, and the top end of the second thrust spring is fixedly connected to the bottom of the piston chamber.

[0014] Further, the size of the first sliding rod is larger than the size of the first air hole. When the first sliding rod leaves the negative pressure chamber inside the sliding column, it is communicated with the second hose.

[0015] Further, an inclined card slot is formed inside each sliding column. The parts of the first sliding rod and the second sliding rod inserted into the sliding column are both inclined. The inclined card slot is used for the insertion of the first sliding rod and the second sliding rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting the forging drive assembly in this application, it is possible to reduce the over-forging of the bracket raw material by the forging head, resulting in quality problems of the bracket raw material. At the same time, when the forging head impacts the mold body, the bracket raw 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 bracket raw material at different stages is the same, then the thinner the bracket raw material, the greater the impact force on the mold body, and the mold body is more likely to be damaged, effectively ensuring the service life of the mold body; (2) In this application, by setting the second hose, the retention chamber, the negative pressure chamber, the first air hole, the second air hole, and the suction holes, the forged bracket raw material is firmly sucked. 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, causing the forging head to move slightly upward, and a part of the bracket raw material leaks out of the mold. At this time, the bracket raw material is fixed, and the air pump continues to work to make the forging head move upward and reset. At this time, the bracket raw material is taken out, which can assist in taking out the forged bracket raw material, facilitating the staff to take out the forged bracket raw material, effectively saving the demolding time of the bracket raw material and improving work efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 8, a forging device for a photovoltaic panel support, comprising a frame body 1. A die body 2 is fixedly arranged at the bottom of the frame body 1, and the die body 2 is used for placing the support raw material. A forging drive assembly 3 is fixedly arranged on the frame body 1. A forging head 4 is arranged at the bottom of the forging drive assembly 3, and the forging head 4 is adapted to the die body 2. The forging drive assembly 3 is used to realize the forging action of the forging head 4 on the support raw material. The forging drive assembly 3 includes an air pump 5 fixedly arranged on the frame body 1. A sleeve 6 is also fixedly installed on the frame body 1. A piston body 7 is slidably and sealingly arranged inside the sleeve 6. The inside of 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 communicated with the pressurizing chamber 8. The space above the piston body 7 inside the sleeve 6 is the pressurizing chamber 8, and the space below the piston body 7 inside the sleeve 6 is the piston chamber 9. A push rod 10 is fixedly connected to the bottom of the piston chamber 9. The push rod 10 extends downward outside the piston chamber 9 and is fixedly connected to the forging head 4. A flow hole 11 communicating with the air is opened on the bottom wall of the piston chamber 9. The amount of gas input by the air pump 5 into the pressurizing chamber 8 each time is the same.

[0021] When using the device to forge the support raw material, first place the support raw material in the die body 2, and then make the air pump 5 work through an external control console to inject gas into the inside of the pressurizing chamber 8. When gas enters the pressurizing chamber 8, the gas will push the piston body 7 to move downward, and the gas in the piston chamber 9 will be discharged through the flow hole 11. Then the piston body 7 will move downward together with the push rod 10, thereby realizing the purpose of the forging head 4 hammering the support raw material. Then the air pump 5 sucks out the gas inside the pressurizing chamber 8. At this time, the piston chamber 9 inhales air through the flow hole 11, so that the piston body 7 moves upward together with the push rod 10 and the forging head 4. The air pump 5 works repeatedly to achieve the forging effect on the support raw material. Under the condition that the volume of gas injected by the air pump 5 into the pressurizing chamber 8 each time is the same, a part of the air pressure will be used for the moving action of pushing the forging head 4 and the push rod 10. Since the thickness of the support raw material will gradually become smaller during each forging, the downward movement distance of the push rod 10 and the forging head 4 will gradually increase, and the air pressure used for the moving action of pushing the forging head 4 will become more, while the remaining air pressure used for forging the support raw material will gradually decrease, making the force generated by the forging head 4 on the support raw material during forging smaller, reducing the quality problems of the support raw material caused by excessive forging of the forging head 4 on the support raw material. At the same time, when the forging head 4 impacts the die body 2, the support raw material can buffer the impact force of the forging head 4 on the die body 2 to a certain extent. If the impact force of the forging head 4 on the support raw material at different stages is the same, then the thinner the support raw material, the greater the impact force on the die body 2, and the die body 2 is more likely to be damaged, effectively ensuring the service life of the die body 2; It should be particularly noted here that: the top of the air pump 5 is connected to the outside air through a hose, and the external control console is used to control the start and stop of the air pump 5. The air injected by the air pump 5 into the pressurizing chamber 8 each time can make the piston body 7 move from the top of the sleeve 6 to the bottom of the sleeve 6.

[0022] As Figures 1 to 3 shown, a retention cavity 12 is formed inside the forging head 4, and a plurality of suction holes 13 are formed at the bottom of the forging head 4. The suction holes 13 extend upward and communicate with the retention cavity 12. An annular housing 14 is fixedly sleeved on the outer surface of the sleeve 6. A through hole 15 is formed at the bottom of the inner wall of the sleeve 6. A buffer groove 16 is formed inside the annular housing 14. The through hole 15 is located at the bottom of the buffer groove 16 and communicates with the buffer groove 16. Oil cavities 17 and a negative pressure cavity 18 that do not communicate with each other are respectively formed on both sides of the annular housing 14. A first one-way valve 19 is fixedly arranged on one side of the inner wall of the top of the buffer groove 16. A first hose 20 is fixedly inserted at the bottom of the oil cavity 17. The oil cavity 17 communicates with the retention cavity 12 through the first hose 20. The first one-way valve 19 is used to send the gas in the buffer groove 16 into the oil cavity 17.

[0023] When the forging drive assembly 3 starts to work, the push rod 10 moves downward as shown in Figure 2 . At this time, 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 interior of the oil cavity 17 through the first one-way valve 19, thereby increasing the amount of lubricating oil in the oil cavity 17. The lubricating oil in the oil cavity 17 is sent into the retention cavity 12 through the first hose 20, and then is diverted to the suction holes 13 through the retention cavity 12 and sprayed from the suction holes 13 onto the bracket raw material at the bottom of the forging head 4. Spraying lubricating oil during forging can effectively reduce the forging force required for forging the bracket raw material. Even if a part of the air pressure is used for other purposes, the forging head 4 can still have the forging effect on the bracket raw material.

[0024] As Figure 3 - Figure 8 shown, a second one-way valve 21 is fixedly arranged on the other side of the inner wall of the top of the buffer groove 16. The air in the negative pressure cavity 18 enters the buffer groove 16 through the second one-way valve 21. A second hose 22 is fixedly inserted at the bottom of the negative pressure cavity 18. The negative pressure cavity 18 communicates with the retention cavity 12 through the second hose 22.

[0025] Two sets of sliding columns 23 are slidably and sealingly arranged at the bottom of the piston chamber 9. Two sets of circular sliding grooves 24 are symmetrically formed at the bottom of the sleeve 6. A first sliding rod 25 is slidably and sealingly arranged in one of the circular sliding grooves 24. A first air hole 26 is formed at the bottom of the annular housing 14. The first air hole 26 communicates the negative pressure cavity 18 with the second hose 22. A second air hole 27 is formed on the first sliding rod 25. One end of the first sliding rod 25 is located inside the sliding column 23. A first thrust spring 28 is arranged in each of the circular sliding grooves 24. 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 sliding groove 24.

[0026] The size of the first sliding rod 25 is larger than that of the first air hole 26. The first sliding rod 25 leaves the internal negative pressure chamber 18 of the sliding column 23 and is connected to the second hose 22.

[0027] An inclined card slot 39 is formed inside each group of sliding columns 23. The part of the first sliding rod 25 inserted into the sliding column 23 is inclined. The inclined card slot 39 is used for the insertion of the first sliding rod 25 and the second sliding rod 29.

[0028] A second thrust spring 38 is sleeved on the outer surface of each group of sliding columns 23. The top end of the second thrust spring 38 is fixedly connected to the top end of the outer surface of the sliding column 23, and the top end of the second thrust spring 38 is fixedly connected to the bottom of the piston chamber 9.

[0029] When the device has completed the forging operation of the bracket raw material, the piston main body 7 has moved to the bottom end in the piston chamber 9 at this time. The piston main body 7 will press down the sliding column 23 at this time, and at the same time make the second thrust spring 38 contract. As the sliding column 23 moves downward, under the action of the inclined card slot 39 inside the sliding column 23, the first sliding rod 25 will move to the right through its inclined surface as shown in Figure 3 , so that a small slit for gas passage is left between the first air hole 26 and the second air hole 27. Then, under the action of the gas in the negative pressure chamber 18, the forged bracket raw material is firmly sucked through the second hose 22, the retention chamber 12 and the suction hole 13. At this time, the external control console makes the air pump 5 work to suck out a small part of the gas in the pressurization chamber 8, so that the forging head 4 moves upward slightly, and a part of the bracket raw material is exposed from the mold. At this time, the bracket raw material is fixed, and the air pump 5 continues to work to make the forging head 4 move upward and reset. At this time, the bracket raw material is taken out, which can assist in taking out the forged bracket raw material, facilitating the staff to take out the forged bracket raw material, effectively saving the demolding time of the bracket raw material and improving the work efficiency; After each impact of the forging head 4 on the bracket raw material, the piston main body 7 moves upward. At this time, the piston chamber 9 will inhale 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 pumped out. As the number of impacts of the forging head 4 increases, the gas content in the negative pressure chamber 18 becomes less, achieving the purpose of having negative pressure inside the negative pressure chamber 18, which is convenient for subsequent operations to assist the demolding of the bracket raw material; As Figures 2 to 7 shown, a second sliding rod 29 is slidably and sealingly arranged in another group of circular sliding grooves 24. A third air hole 30 is formed on the second sliding rod 29. A fourth air hole 31 is formed 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 static state, the third air hole 30 is connected to the fourth air hole 31. The part of the second sliding rod 29 inserted into the sliding column 23 is inclined.

[0030] When the second sliding rod 29 is in the initial state, the third air hole 30 and the fourth air hole 31 are in communication with each other.

[0031] When the piston body 7 presses down the sliding column 23, the sliding column 23 moves downward. At the same time, the second push rod 10 will move leftward as shown in Figure 3 and shown in the figure, and then the third air hole 30 and the fourth air hole 31 will gradually become non - communicating with each other until the device has completed the forging operation of the bracket raw material. When the device starts to assist the mold body 2 in discharging materials, in order to avoid oil spraying at this time and causing the bracket raw material to fall, the fourth air hole 31 blocked by the second sliding rod 29 cannot inject lubricating oil into the retention cavity 12 and the suction holes 13 through the third air hole 30. At this time, the first hose 20 can be regarded as closed, which further ensures the vacuum inside the forging head 4 used to suck up the bracket raw material when the negative pressure cavity 18 is working, ensures the suction force of the forging head 4, and ensures the safety of the forging head 4 to assist in discharging materials; It should be specifically noted here that: the size of the second sliding rod 29 is larger than the size of the fourth air hole 31.

[0032] As Figures 3 to 7 shown, one end of the first sliding rod 25 close to the first thrust spring 28 is a magnetic block 32. A set of conductive sliding grooves 33 used in cooperation with the magnetic block 32 are also opened at the bottom of the annular housing 14. A conductive iron block 34 is slidably arranged inside the conductive sliding grooves 33. A tension spring 35 is also arranged inside the conductive sliding grooves 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 sliding grooves 33. A warning light 36 is fixedly arranged on the outer surface of the annular housing 14. When the conductive sliding grooves 33 come into contact with the conductive iron block 34, the warning light 36 will light up.

[0033] The inner wall of one end of the conductive sliding grooves 33 close to the warning 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 warning light 36 are electrically connected to each other. The conductive iron block 34 is an iron block with copper wires attached to its surface, and the copper wires are attached perpendicular to the horizontal plane.

[0034] When the forging operation of the bracket raw material is completed, at this time, since the first sliding rod 25 moves rightward as shown in Figure 3 and shown in the figure, and drives the magnetic block 32 to move rightward together in the circular sliding groove 24. At the same time, the first thrust spring 28 contracts. At this time, the magnetic block 32 has moved to the rightmost end of the circular sliding groove 24. Due to the magnetic force of the magnetic block 32, it will attract the conductive iron block 34 originally used to keep the warning light 36 lit in the conductive sliding grooves 33, and make the conductive iron block 34 move towards the magnetic block 32. Since the conductive iron block 34 leaves the part of the annular conductive plate 37 of the conductive sliding grooves 33, at this time, the warning light 36 will stop lighting, indicating that the forging operation is over and reminding the staff.

[0035] Usage method: When forging the bracket raw material using the device, first place the bracket raw material in the mold body 2, and then make the air pump 5 work through an external console to inject gas into the inside of the pressurizing chamber 8. When gas enters the pressurizing chamber 8, the gas will push the piston body 7 to move downward, and discharge the gas in the piston chamber 9 through the flow hole 11. Furthermore, the piston body 7 will move downward together with the push rod 10, thereby achieving the purpose of the forging head 4 hammering the bracket raw material. Subsequently, the air pump 5 sucks out the gas inside the pressurizing chamber 8. At this time, the piston chamber 9 inhales air into the inside through the flow hole 11, thereby making the piston body 7 move upward together with the push rod 10 and the forging head 4. The air pump 5 works repeatedly to achieve the forging effect on the bracket raw material.

[0036] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
