Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of forging, and particularly relates to a rapid forging hydraulic press. Background Art
[0002] A forging hydraulic press is a processing equipment that uses a hydraulic cylinder to apply pressure to a metal blank, so that the metal blank undergoes plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. The forging hydraulic press can be divided into a free forging hydraulic press and a die forging hydraulic press. The die forging hydraulic press places a hot metal blank in a mold, and then uses a hydraulic cylinder to apply pressure to the hot metal blank. After being stamped, the hot metal blank will become the same shape as the working surface of the mold. However, during the forging process of the hot metal blank, residues such as metal chips and oxide scales will remain in the mold. If these residues are not cleaned in the mold, they will affect the shape and size of the metal blank after stamping, thereby affecting the accuracy of the formed workpiece.

[0030] 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.
[0031] Please refer to Figures 1 to 8 , the present invention provides a fast forging hydraulic press, and the technical solution is as follows:
[0032] A fast forging hydraulic press, characterized in that: it includes a housing 1, both ends of the housing 1 are respectively provided with a first opening 2 and a second opening 3 communicating with the inside, the outer side wall of the housing 1 is fixedly installed with a first support plate 4, and the first support plate 4 is located below the first opening 2, the top wall of the first support plate 4 is fixedly installed with a first cylinder 5, the output end of the first cylinder 5 is fixedly installed with a movable plate 6, one end of the movable plate 6 away from the first cylinder 5 is installed with a demoulding agent spraying mechanism 7, the inner bottom wall of the housing 1 is provided with a mold 8, a punch 9 is provided directly above the mold 8, a hydraulic cylinder 11 is fixedly installed between the punch 9 and the inner wall of the housing 1, and the outer side wall of the housing 1 away from the first support plate 4 is fixedly installed with a second support plate 12, and the second support plate 12 is located below the second opening 3;
[0033] A cleaning mechanism is installed on the second support plate 12. The cleaning mechanism is used to clean residues such as metal chips and scale remaining on the mold 8.
[0034] A lifting and flipping mechanism is installed in the housing 1. The lifting and flipping mechanism is used to lift and flip the mold 8, facilitating the cleaning mechanism to clean residues such as metal chips and scale remaining on the mold 8.
[0035] During the forging process of placing the hot blank in the mold 8, after the hot blank is stamped, there will be scale and iron chips remaining in the mold 8. When the punch 9 moves upward, it activates the lifting and flipping mechanism to raise the mold 8. After raising, it drives the working surface of the mold 8 to flip to the side of the cleaning mechanism, making the inner side wall of the mold 8 face the cleaning mechanism. During the tilting process of the mold 8, the cleaning mechanism is triggered, enabling the cleaning mechanism to clean residues such as metal chips and scale remaining on the mold 8 during the tilting process of the mold 8. After cleaning, the mold 8 returns to the horizontal plane and then reversely flips to the side of the mold release agent spraying mechanism 7, making the inner side wall of the mold 8 face the mold release agent spraying mechanism 7. Similarly, during the tilting process of the mold 8, the mold release machine spraying mechanism is triggered, enabling the mold release machine spraying mechanism to leave the mold release agent on the mold 8 during the tilting process of the mold 8 for better demolding.
[0036] As an implementation manner of the present invention, a cooling cylinder 13 is fixedly installed on the outer side wall of the mold 8, and the cooling cylinder 13 is in contact with the outer side wall of the mold 8. Cooling water is contained in the cooling cylinder 13. A cooling pump 14 is installed on one side of the cooling cylinder 13. A water inlet pipe 15 is connected to the cooling pump 14, and the water inlet pipe 15 is communicated with the cooling cylinder 13. A drain pipe 16 is installed on the side of the cooling cylinder 13 away from the water inlet end.
[0037] When the hot blank is placed in the mold 8 for forging, the hot blank comes into contact with the mold 8, and the hot blank will emit a large amount of heat, which is quickly transferred to the mold 8. The longer the contact time between the hot blank and the mold 8, the higher the temperature of the mold 8 will be, which will affect the strength of the mold 8. In the existing process, most use spraying mold release agent on the surface for cooling, which requires a large amount of mold release agent. By installing the cooling cylinder 13 on the outer side wall of the mold 8, the heat transferred from the inner wall of the mold 8 to the outer wall is absorbed, enabling the mold 8 to be cooled and the amount of mold release agent used to be reduced. When the cooling water temperature in the cooling cylinder 13 reaches a certain temperature, the cooling pump 14 is started, and the cooling water is discharged from the water inlet pipe 15, and the heated cooling water in the cooling cylinder 13 is discharged from the drain pipe 16. The cooling cylinder 13 continuously absorbs the heat from the outer wall of the mold 8 to achieve the effect of continuously cooling the mold 8.
[0038] As an implementation manner of the present invention, a temperature detection mechanism is fixedly installed on the inner bottom wall of the cooling cylinder 13. The temperature detection mechanism includes a gas storage cylinder 17 installed on the inner bottom wall of the cooling cylinder 13. The gas storage cylinder 17 is filled with air. A sealing cover 18 is fixedly installed at the top opening of the gas storage cylinder 17. A guide air pipe 19 is fixedly installed on the top wall of the sealing cover 18. The sealing cover 18 is provided with an opening that cooperates with the guide air pipe 19. The top end of the guide air pipe 19 is fixedly installed with a piston cylinder 21. A piston 22 is slidably installed on the inner side wall of the piston cylinder 21. Metal blocks 23 are symmetrically fixedly installed on the top wall of the piston 22 and the inner top wall of the piston cylinder 21. The two metal blocks 23 are connected in series with the cooling pump 14 and control the on-off of the metal blocks 23. A return spring 24 is connected between the top wall of the piston 22 and the inner top wall of the piston cylinder 21. A protective cover 25 is fixedly installed on the top wall of the gas storage cylinder 17;
[0039] When the hot blank is placed on the mold 8 for forging, the hot blank contacts the working surface of the mold 8, and the hot blank will emit a large amount of heat and quickly transfer it to the working surface of the mold 8. The heat inside the mold 8 is continuously transferred to the outer wall of the mold 8. The cooling cylinder 13 continuously absorbs the heat dissipated from the outer wall of the mold 8, causing the temperature of the cooling water in the cooling cylinder 13 to continuously rise. The air in the gas storage cylinder 17 expands in volume when heated, driving the piston 22 to move upward along the piston cylinder 21. When the piston 22 moves upward so that the two metal blocks 23 are in contact with each other, the two metal blocks 23 form a circuit, and the cooling pump 14 is started. When the temperature of the outer wall of the mold 8 decreases, the dissipated heat also decreases accordingly, causing the heat absorbed by the cooling cylinder 13 to decrease and the temperature of the cooling water to decrease. The volume of the air in the gas storage cylinder 17 decreases, thereby driving the piston 22 to move downward, causing the two metal blocks 23 to disconnect, and the cooling pump 14 is powered off and stops operating; In order to improve the sensitivity to temperature, substances with a relatively large coefficient of thermal expansion, such as alcohol, can be stored in the gas storage cylinder 17.
[0040] As an implementation manner of the present invention, a trigger switch one 26 is fixedly installed on the top surface of the cooling cylinder 13 in the direction of the second support plate 12, and a trigger switch two 27 is fixedly installed on the top surface of the cooling cylinder 13 in the direction of the first support plate 4;
[0041] During the process of the lifting and flipping mechanism tilting the working surface of the mold 8 towards the cleaning mechanism, the trigger switch one 26 is contacted to activate the cleaning mechanism and achieve automatic cleaning of the inside of the mold 8; and when the lifting and flipping mechanism rotates in the reverse direction to tilt the working surface of the mold 8 towards the mold release agent spraying mechanism 7, the trigger switch two 27 is contacted to activate the mold release agent spraying mechanism 7 and achieve the effect of spraying the mold release agent on the inner wall of the mold 8.
[0042] As an implementation manner of the present invention, the cleaning mechanism includes two cylinders two 28 symmetrically and fixedly installed on the second support plate 12. The output ends of the two cylinders two 28 are jointly fixedly installed with a cylinder three 29. The output end of the cylinder three 29 is fixedly installed with a moving plate 31. The outer side wall of the moving plate 31 is uniformly fixedly installed with three jet nozzles 32. The jet nozzles 32 are all connected to the high-pressure gas output mechanism;
[0043] When the lifting and flipping mechanism turns the working surface of the mold 8 towards the cleaning mechanism, the mold 8 will contact the trigger switch one 26, and then the driving cylinder three 29 is started to drive the multiple jet nozzles 32 to approach the mold 8, and the high-pressure gas output mechanism is started. During the process of the mold 8 continuing to tilt to 90°, the high-pressure gas is ejected from the multiple jet nozzles 32, and the residues in the mold 8 are removed by the high-pressure gas. The ejected residues will be collected by the collection frames on both sides of the outer shell 1. The two cylinders two 28 are jointly driven to drive the multiple jet nozzles 32 to move up and down, so that the high-pressure gas can be blown to various positions of the working surface of the mold 8, thereby removing the residues at various positions in the mold 8.
[0044] As an implementation manner of the present invention, the lifting and flipping mechanism includes a telescopic air cylinder one 33 fixedly installed in a groove opened at the bottom of the housing 1. A telescopic air cylinder two 34 is fixed between the punch 9 and the inner wall of the housing 1. The telescopic air cylinder two 34 is communicated with a trachea 35 inside the housing 1. One end of the trachea 35 away from the telescopic air cylinder two 34 is communicated with the bottom of the telescopic air cylinder one 33. The output end of the telescopic air cylinder one 33 is fixedly installed with a bottom plate 36; at the four corners above the bottom plate 36, a support frame 37 with an opening at the top is fixedly installed. A support rod 38 is rotatably placed on the top opening of the support frame 37. The end of the support rod 38 extends beyond the outer side wall of the support frame 37. A half gear 39 is fixedly installed at the end of the support rod 38. A receiving plate 41 is fixedly installed on the support rod 38. The receiving plate 41 is fixedly installed with the mold 8;
[0045] The two side walls of the bottom plate 36 are slidably connected with a push plate 42. On both sides of the push plate 42 on one side wall of the bottom plate 36, a side plate 43 and an L-shaped sliding plate 44 are sequentially arranged. The side plate 43 is fixedly connected with the bottom plate 36. The L-shaped sliding plate 44 is slidably connected with the bottom plate 36. A rack 45 is arranged on the side of the L-shaped sliding plate 44 away from the bottom. The relative positions of the rack 45 and the half gear 39 can be meshed. A guide rod 46 is fixedly installed between the L-shaped sliding plates 44. The guide rod 46 penetrates through the side plate 43 and the push plate 42. The guide rod 46 is slidably connected with the side plate 43. The guide rod 46 is fixedly connected with the push plate 42. A push rod 47 is fixedly installed between one of the side plates 43 and the push plate 42;
[0046] In the initial state, the rack 45 near the cleaning mechanism and the demolding agent spraying mechanism 7 is not engaged with the half gear 39. When the rack 45 moves towards the side close to the cleaning mechanism, the rack 45 on the side close to the cleaning mechanism meshes with the half gear 39, so that the rack 45 drives the half gear 39 to rotate, realizing the flipping of the bottom plate 36 towards the side close to the cleaning mechanism. The rack 45 on the other side close to the demolding agent spraying device 7 is not engaged with the half gear 39 to avoid interference;
[0047] On the contrary, when the rack 45 moves towards the side close to the demolding agent spraying mechanism 7, the rack 45 on the side close to the demolding agent spraying mechanism 7 meshes with the half gear 39, so that the rack 45 drives the half gear 39 to rotate, realizing the flipping of the bottom plate 36 towards the side close to the demolding agent spraying mechanism 7. The rack 45 on the other side close to the cleaning mechanism is not engaged with the half gear 39 to avoid interference;
[0048] After the hot blank is forged by the forging die 8, the driving hydraulic cylinder 11 drives the punch 9 to move upward. When the punch 9 moves upward, it squeezes the telescopic air cylinder two 34. The telescopic air cylinder two 34 compresses its volume, and the gas inside it is transported to the telescopic air cylinder one 33 through the air pipe 35. The gas in the telescopic air cylinder one 33 increases, and then pushes the bottom plate 36 upward. The die 8 moves upward accordingly. When the bottom wall of the upward moving bottom plate 36 exceeds the outer top wall of the cooling cylinder 13, the forged workpiece is taken out;
[0049] A bypass valve is installed on the air pipe 35. During normal forging, the bypass valve conducts the air pipe 35 to the outside, so that the gas in the telescopic air cylinder two 34 is vented to the outside, ensuring that the telescopic air cylinder one 33 remains stationary during the stamping process and guaranteeing the stability of stamping. When it is necessary to use the telescopic air cylinder two 34 to lift the telescopic air cylinder one 33, the bypass valve is closed to ensure the connection between the telescopic air cylinder two 34 and the telescopic air cylinder one 33;
[0050] Next, drive the push rod 47. The push rod 47 moves horizontally. The moving end of the push rod 47 drives the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to move towards the cleaning mechanism. As the L-shaped slide plate 44 moves, the rack 45 meshes with the half gear 39 for transmission, thereby driving the support rod 38 to rotate on the support frame 37. Since the support rod 38 is fixedly connected to the receiving plate 41, when the support rod 38 rotates, the receiving plate 41 is driven to achieve the purpose of flipping. Consequently, the mold 8 on the receiving plate 41 also reaches the purpose of flipping. As the receiving plate 41 and the mold 8 flip, they gradually approach the cleaning mechanism. Moreover, since the size of the mold 8 is larger than that of the bottom plate 36, the mold 8 will contact and squeeze the trigger switch 1 26, thereby driving the cleaning mechanism to operate, achieving the cleaning of the residues inside the mold 8 and avoiding the impact on the quality of the hot blank during the next forging. When the mold 8 rotates 90°, control the push rod 47 to move in the opposite direction. The moving end of the push rod 47 drives the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to move towards the mold release agent spraying mechanism 7. As the L-shaped slide plate 44 moves, the rack 45 on the side close to the cleaning mechanism disengages from the half gear 39, and the rack 45 on the side close to the mold release agent spraying mechanism 7 meshes with the half gear 39. During this process, the bottom plate 36 and the mold 8 will change from the flipped state to the horizontal state and then to the opposite flipped state, thereby driving the support rod 38 on the side close to the mold release agent spraying mechanism 7 to rotate on the support frame 37, and then driving the receiving plate 41 and the mold 8 to flip. The gradually flipping mold 8 contacts and squeezes the trigger switch 2 27, thereby driving the mold release agent spraying mechanism 7 to spray the mold release agent into the mold 8, facilitating the demolding of the hot blank. After the mold 8 rotates 90°, control the push rod 47 to drive the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to reset, in preparation for cleaning the mold 8 and spraying the mold release agent after the next demolding. After resetting, the mold 8 and the receiving plate 41 are in the horizontal state. This design method is also beneficial for the rapid replacement of the mold 8.
[0051] As an embodiment of the present invention, support columns 48 fixedly installed with the groove are provided on both sides of the telescopic air cylinder 1 33. The support columns 48 abut against the bottom plate 36. The notch size of the groove opened in the housing 1 is smaller than the size of the mold 8. The length of the bottom plate 36 is smaller than the length of the groove opening.
[0052] When the telescopic air cylinder 1 33 is not operating, the telescopic air cylinder 1 33 needs to bear the pressure of the bottom plate 36 and the devices installed on the bottom plate 36. By installing the support columns 48 on both sides of the telescopic air cylinder 1 33, and at the same time the groove can also give a certain supporting force to the mold 8, the load borne by the telescopic air cylinder 1 33 can be effectively dispersed, increasing the service life of the telescopic air cylinder 1 33.
[0053] As an embodiment of the present invention, the push rod 47 is an electric push rod.
[0054] Set parameters through the electric push rod. When the bottom of the bottom plate 36 is higher than the cooling cylinder 13, drive it so that the bottom plate 36 and the mold 8 are first flipped from the horizontal state to 90° towards the cleaning mechanism direction, then restored to the horizontal state and immediately flipped to 90° towards the mold release agent spraying mechanism 7 direction, and finally drive the bottom plate 36 and the mold 8 to return to the horizontal state, accurately and automatically controlling the sequence of rotation directions and flipping angles of the bottom plate 36 and the mold 8 to ensure the cleaning of the residues in the mold 8 and the uniform spraying of the mold release agent.
[0055] Working principle: After the operator puts the hot blank into the mold 8, start the hydraulic cylinder 11 to drive the punch 9 to move downward. At the same time, the internal volume of the telescopic air cylinder two 34 expands, and the gas in the telescopic air cylinder one 33 is drawn back, so that the telescopic air cylinder one 33 drives the bottom plate 36 and the mold 8 to move downward, so that the hot blank in the mold 8 is pressed down by the punch 9 after being stabilized.
[0056] The hot blank contacts the working surface of the mold 8, and the hot blank will emit a large amount of heat and quickly transfer it to the working surface of the mold 8. The heat inside the mold 8 is continuously transferred to the outer wall of the mold 8. The cooling cylinder 13 continuously absorbs the heat dissipated from the outer wall of the mold 8, causing the temperature of the cooling water in the cooling cylinder 13 to continuously rise. The air in the gas storage cylinder 17 expands when heated, driving the piston 22 to move upward along the piston cylinder 21. When the piston 22 moves upward so that the two metal blocks 23 are in contact with each other, the two metal blocks 23 form a circuit, and the cooling pump 14 is started. When the temperature of the outer wall of the mold 8 decreases, the dissipated heat will also decrease accordingly, causing the heat absorbed by the cooling cylinder 13 to decrease, the temperature of the cooling water to decrease, the volume of the air in the gas storage cylinder 17 to decrease, thereby driving the piston 22 to move downward, causing the two metal blocks 23 to disconnect, and the cooling pump 14 to power off and stop running.
[0057] After the hot blank is forged by the forging die 8, the driving hydraulic cylinder 11 drives the punch 9 to move upward. When the punch 9 moves upward, it squeezes the telescopic air cylinder II 34. The telescopic air cylinder II 34 compresses its volume, and the gas inside it is transported through the air pipe 35 to the telescopic air cylinder I 33. The gas in the telescopic air cylinder I 33 increases, and then pushes the bottom plate 36 to move upward, and the die 8 moves upward accordingly. When the bottom wall of the upward-moving bottom plate 36 exceeds the outer top wall of the cooling cylinder 13, the forged workpiece is taken out. Then, the push rod 47 is driven, and the push rod 47 moves in the horizontal direction. The moving end of the push rod 47 drives the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to move towards the cleaning mechanism. As the L-shaped slide plate 44 moves, the rack 45 on the side close to the cleaning mechanism disengages from the half gear 39, and the rack 45 on the side close to the mold release agent spraying device 7 engages with the half gear 39. During this process, the bottom plate 36 and the die 8 will change from the flipped state to the horizontal state and then to the opposite flipped state, thereby driving the support rod 38 to rotate on the support frame 37. Since the support rod 38 is fixedly connected to the receiving plate 41, the support rod 38 rotates, thereby driving the receiving plate 41 to achieve the purpose of flipping. Subsequently, the die 8 on the receiving plate 41 also achieves the purpose of flipping. As the receiving plate 41 and the die 8 flip, they gradually approach the cleaning mechanism. Moreover, the size of the die 8 is larger than that of the bottom plate 36, and the die 8 will contact and squeeze the trigger switch I 26, thereby driving the cleaning mechanism to operate, realizing the cleaning of the residues inside the die 8, and avoiding affecting the quality of the hot blank during the next forging; when the die 8 rotates 90°, the push rod 47 is controlled to move in the opposite direction. The moving end of the push rod 47 drives the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to move towards the mold release agent spraying mechanism 7. As the L-shaped slide plate 44 moves, the rack 45 engages and drives with the half gear 39, thereby driving the support rod 38 on the side close to the mold release agent spraying mechanism 7 to rotate on the support frame 37, and then driving the receiving plate 41 and the die 8 to flip. The gradually flipped die 8 contacts and squeezes the trigger switch II 27, thereby driving the mold release agent spraying mechanism 7 to spray the mold release agent into the die 8, facilitating the demolding of the hot blank. After the die 8 rotates 90°, the push rod 47 is controlled to drive the push plate 42, the guide rod 46, and the L-shaped slide plate 44 to reset, in preparation for cleaning the die 8 and spraying the mold release agent after the next demolding. After resetting, the die 8 and the receiving plate 41 are in the horizontal state.
