Description

Technical Field

[0001] The present invention relates to the technical field of presses, and in particular to a hot die forging pressure device with a fast die release function. Background Art

[0002] In current existing hot die forging presses, problems such as the thickness of the workpiece material not matching the forging die, the placement position of the forging material being offset, and insufficient forging pressure often cause difficulties in separating the upper and lower dies, as well as between the die and the workpiece, resulting in a die sticking phenomenon, leading to equipment malfunctions and potential safety hazards. At the same time, in the prior art, the die changeover and installation take a long time, and the die installation efficiency is low. Workers mostly manually load and unload workpieces during the operation of the hot die forging press, and the production efficiency is closely related to the physical strength of the workers. To solve the above problems, a hot die forging pressure device with a fast die release function is needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a hot die forging pressure device with a fast die release function to solve the problems proposed in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution:

[0005] The hot die forging pressure device includes a press main body, a die unit, a knockout unit, a conveying unit, and a spraying unit. The die unit is fixedly connected to the press main body. One end of the knockout unit is drivingly connected to the press main body, and the other end of the knockout unit is slidably connected to the press main body. The knockout unit is slidably connected to the die unit. The conveying unit is fixedly connected to the press main body. The die unit is located between the conveying units. The spraying unit is fixedly connected to the conveying unit, and the spraying unit faces the die unit.

[0006] When the present invention works, the conveying unit clamps the workpiece to the die unit. Subsequently, the spraying unit sprays a release agent into the mold cavity of the die unit to facilitate the subsequent die release between the die unit and the workpiece, preventing the loss of the die unit and the workpiece due to mutual adhesion. Subsequently, the press main body cooperates with the die unit to be responsible for forging and forming the workpiece. At the same time, the press main body drives the knockout unit to be responsible for ejecting the forged and formed workpiece from the die unit. The conveying unit then clamps and conveys the formed workpiece. The whole process of equipment operation is automated, improving the production efficiency and resource utilization rate.

[0007] Furthermore, the press body includes a housing, a workbench, a fixed plate, a transmission slider, a transmission unit, and a pin. The workbench is fixedly connected to the housing, and the workbench is slidably connected to the ejector unit. A die unit is placed on the workbench. The two fixed plates are connected to the inner wall surfaces on both sides of the housing by screws. The transmission slider is located between the two fixed plates, and both ends of the transmission slider are slidably connected to the two fixed plates respectively. The upper end of the transmission slider is connected to the transmission unit. A notch is provided at the bottom end of the transmission slider. Two positioning columns are provided in the notch of the transmission slider. Through holes are provided at one ends of the two positioning columns extending out of the notch of the transmission slider. The two positioning columns pass through the die unit, and the pin passes through the through holes at one ends of the two positioning columns. One end of the pin contacts the die unit. The transmission unit passes through the housing, and the transmission unit is in transmission connection with the ejector unit.

[0008] The transmission unit drives the transmission slider to slide between the two fixed plates, thereby driving the die unit. The two positioning columns on the transmission slider pass through the die unit, and the die unit is locked by cooperating with the pin. This method is more convenient and quicker compared with the traditional bolt connection method.

[0009] Furthermore, the transmission unit includes a rotating motor, a transmission part, a pulley, a belt, a clutch, a transmission rod, a transmission gear, an eccentric crankshaft, and a connecting rod. The rotating motor is fixedly connected to the top of the housing, and the rotor of the rotating motor is fixedly connected to the transmission part. One end of all the belts is in transmission connection with the transmission part, and the other end of part of the belts is in transmission connection with the pulley, and the other part of the belts is in transmission connection with the ejector unit. The transmission rod passes through the housing and the pulley, and the transmission rod is fixedly connected to the pulley. One end of the transmission rod passing through the pulley is connected to the clutch, and a small gear is provided at the other end of the transmission rod. The small gear at one end of the transmission rod meshes with the transmission gear, and the transmission gear is fixedly connected to one end of the eccentric crankshaft. The eccentric crankshaft penetrates into the housing, and the other end of the eccentric crankshaft is rotatably connected to the housing. One end of the connecting rod is sleeved on the bent section of the eccentric crankshaft, and the connecting rod is rotatably connected to the eccentric crankshaft. The other end of the connecting rod is movably connected to the upper end of the transmission slider.

[0010] The rotating motor drives the transmission part to rotate. The transmission part drives the pulley to rotate through the belt. At the same time, the transmission part also drives the operation of the ejector unit through the belt. The pulley drives the transmission gear to rotate through the transmission rod. The transmission gear drives the eccentric crankshaft to rotate. One end of the connecting rod is sleeved on the bent section of the eccentric crankshaft, and the other end of the connecting rod is movably connected to the upper end of the transmission slider. Since the transmission slider can only move up and down, the rotation of the eccentric crankshaft can only drive the end of the connecting rod connected to the transmission slider to perform up and down linear displacement, thereby driving the up and down movement of the transmission slider. The clutch can indirectly control the up and down displacement frequency of the transmission slider by controlling the rotation speed of the transmission rod.

[0011] Furthermore, the die unit includes an upper die and a lower die. Two through holes leading from the front end to the rear end are provided on the upper die. The upper die is connected to the two positioning columns of the transmission slider through the two through holes in an inserting and socketing manner. The front end face of the upper die contacts with one end face of the latch. The lower die is placed on the workbench, and a through hole is also provided at the central axis of the mold cavity of the lower die.

[0012] The upper die is connected to the positioning columns of the transmission slider through the through holes, and then the upper die is locked by inserting the latch through the positioning columns, which reduces the time for installing and replacing the upper die and improves the efficiency.

[0013] Furthermore, the workbench includes a bottom plate, rollers and a slideway. The rollers are rotatably connected to the bottom plate. The lower die is placed on the rollers. The slideway passes through the bottom plate. The upper end face of the slideway is lower than the upper end face of the rollers. The central axis of the slideway coincides with the central axis of the mold cavity of the lower die.

[0014] The slideway is slidably connected to the ejecting unit, so that one end of the ejecting unit can only move up and down along the slideway. The rollers are provided to facilitate the installation and replacement of the die unit, reduce the time required for replacing the die unit, and improve the efficiency.

[0015] Furthermore, the ejecting unit includes a fixed seat, a connecting rod, an external planet gear, an internal planet gear, a counterweight, a connecting block, a ejector rod and a connecting piece. One end of the connecting rod passes through the connecting piece and is rotatably connected to the fixed seat. The connecting rod is fixedly connected to the connecting piece. The other end of the connecting rod passes through the external planet gear and is fixedly connected to the counterweight. The central axis of the connecting rod is collinear with the central axis of the external planet gear. The connecting rod is rotatably connected to the external planet gear. The external planet gear is provided with an internal tooth profile. The internal planet gear is provided with an external tooth profile. The internal planet gear meshes with the external planet gear. The center of gravity of the counterweight and the center of the internal planet gear are located on both sides of the axis of the external planet gear. One end of the counterweight passes through the internal planet gear and is rotatably connected to one end of the connecting block. The counterweight passes through the internal planet gear from the central axis of the internal planet gear. One end of the connecting block is rotatably connected to one end of the ejector rod. The other end of the ejector rod is inserted into the slideway at the bottom end of the workbench and the through hole of the lower die. The ejector rod is slidably connected to the slideway of the workbench and the lower die. The upper end face of the ejector rod is flush with the bottom surface of the mold cavity of the lower die at the lowest position.

[0016] Furthermore, the outer diameter of the internal planet gear is half of the inner diameter of the external planet gear. The central axis at the connection between the ejector rod and the connecting block falls on the pitch circle of the internal planet gear.

[0017] The outer diameter of the inner planetary gear is half of the inner diameter of the outer planetary gear. The central axis of the connection between the ejector rod and the connecting block falls on the pitch circle of the inner planetary gear. The top end of the ejector rod is inserted into the slideway of the workbench, so that the two ends of the ejector rod can move back and forth in a straight line up and down. At the same time, a counterweight block is provided to balance the center of gravity, which greatly reduces the overall vibration amplitude of the ejector unit. In addition, the ejector unit can help the workpiece to be demolded in time to prevent the workpiece and the mold unit from sticking.

[0018] Furthermore, the conveying unit includes two bases, two conveying sliders, two mechanical claws and a connecting plate, the connecting plate and the outer shell are fixedly connected, one base is fixedly connected to the connecting plate, and the other base is fixedly connected to the outer shell, and sliding grooves are provided on the opposite surfaces of the two bases, the two conveying sliders are respectively slidably connected to the two bases, the positions of the two conveying sliders on the two bases correspond to each other, the two mechanical claws are respectively slidably connected to the two conveying sliders, and the two mechanical claws face each other.

[0019] The conveying slider slides on the base, and the mechanical claw is slidably connected to the conveying slider, which ensures that the mechanical claw can be displaced in two directions, and at the same time, the two mechanical claws face each other to clamp the workpiece.

[0020] Furthermore, the spray unit includes a storage box and a spray head, wherein the storage box is located inside the outer shell, two of the spray heads and the storage box are connected by a hose, one of the spray heads is fixedly connected to the upper end surface of the mechanical claw, and one of the spray heads faces the model cavity of the upper mold, and another of the spray heads is fixedly connected to the lower end surface of the mechanical claw, and the other of the spray heads faces the model cavity of the lower mold.

[0021] The storage box contains a release agent, and the nozzle is responsible for spraying the release agent into the mold cavity of the mold unit. Spraying the release agent helps the workpiece after die forging to separate from the mold cavity, preventing the workpiece and the mold unit from sticking and causing equipment operation failure.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention makes it more convenient to disassemble and assemble the upper mold and the lower mold.

[0024] 2. The present invention is fully automated, and there is no need for workers to load and unload materials. The mechanical claw can automatically load and unload materials, put the workpiece into the mold cavity, and perform die forging.

[0025] 3. The present invention automatically sprays the release agent, eliminating the need for workers to spray manually, thereby improving work efficiency.

[0026] 4. The present invention connects the transmission unit and the ejecting unit by transmission, thereby improving resource utilization. One rotating motor drives the operation of the transmission unit and the ejecting unit at the same time.

At the same time, a counterweight block is provided at the center of gravity, greatly reducing the overall vibration amplitude of the ejector unit. In addition, the setting of the ejector unit can help the workpiece to be demolded in time and prevent the workpiece from sticking to the mold unit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] 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 scope of protection of the present invention.

[0036] Embodiment: As Figures 1 - 6 shown, the present invention provides a technical solution,

[0037] As Figures 1 - 4 shown, the hot forging press device includes a press main body 1, a die unit 2, a knockout unit 3, a conveying unit 4, and a spraying unit 5. The die unit 2 is fixedly connected to the press main body 1. One end of the knockout unit 3 is drivingly connected to the press main body 1, and the other end of the knockout unit 3 is slidably connected to the press main body 1. The knockout unit 3 is slidably connected to the die unit 2. The conveying unit 4 is fixedly connected to the press main body 1. The die unit 2 is located between the conveying units 4. The spraying unit 5 is fixedly connected to the conveying unit 4, and the spraying unit 5 faces the die unit 2.

[0038] When the present invention works, the conveying unit 4 clamps the workpiece to the die unit 2. Subsequently, the spraying unit 5 sprays the release agent into the mold cavity of the die unit 2, which facilitates the subsequent demolding of the die unit 2 and the workpiece, and prevents the mutual adhesion between the die unit 2 and the workpiece, resulting in the loss of the die unit 2 and the workpiece. Subsequently, the press main body 1 cooperates with the die unit 2 to be responsible for forging and forming the workpiece. At the same time, the press main body 1 drives the knockout unit 3 to be responsible for ejecting the forged and formed workpiece from the die unit 2. The conveying unit 4 then clamps and conveys the formed workpiece. The whole process of the equipment operation is automated, improving the production efficiency and resource utilization rate.

[0039] As Figures 1 - 6 shown, the press main body 1 includes a housing 11, a workbench 12, fixing plates 13, a transmission slider 14, a transmission unit 15, and a pin 16. The workbench 12 is fixedly connected to the housing 11. The workbench 12 is slidably connected to the knockout unit 3. The die unit 2 is placed on the workbench 12. The two fixing plates 13 are connected to the inner wall surfaces on both sides of the housing 11 by screws. The transmission slider 14 is located between the two fixing plates 13. The two side ends of the transmission slider 14 are respectively slidably connected to the two fixing plates 13. The upper end of the transmission slider 14 is connected to the transmission unit 15. A notch is provided at the bottom end of the transmission slider 14. Two positioning columns 17 are provided in the notch of the transmission slider 14. Through holes are provided at one end of the two positioning columns 17 extending out of the notch of the transmission slider 14. The two positioning columns 17 pass through the die unit 2. The pin 16 passes through the through holes at one end of the two positioning columns 17. One end of the pin 16 contacts the die unit 2. The transmission unit 15 passes through the housing 11, and the transmission unit 15 is drivingly connected to the knockout unit 3.

[0040] The drive unit 15 drives the drive slider 14 to slide between the two fixed plates 13, thereby driving the die unit 2. The two positioning columns 17 on the drive slider 14 pass through the die unit 2, and then cooperate with the pin 16 to lock the die unit 2. This method is more convenient and efficient than the traditional bolt connection method.

[0041] As Figure 1 and Figure 2 shown, the drive unit 15 includes a rotating motor 151, a transmission member 152, a pulley 153, a belt 154, a clutch 155, a transmission rod 156, a transmission gear 157, an eccentric crankshaft 158 and a connecting rod 159. The rotating motor 151 is fixedly connected to the top end of the housing 11. The rotor of the rotating motor 151 is fixedly connected to the transmission member 152.

A small gear is provided at the other end of the transmission rod 156. The small gear at one end of the transmission rod 156 meshes with the transmission gear 157. The transmission gear 157 is fixedly connected to one end of the eccentric crankshaft 158. The eccentric crankshaft 158 penetrates into the housing 11, and the other end of the eccentric crankshaft 158 is rotatably connected to the housing 11. One end of the connecting rod 159 is sleeved on the bent section of the eccentric crankshaft 158. The connecting rod 159 is rotatably connected to the eccentric crankshaft 158. The other end of the connecting rod 159 is movably connected to the upper end of the drive slider 14.

[0042] The rotating motor 151 drives the transmission member 152 to rotate. The transmission member 152 drives the pulley 153 to rotate through the belt 154. At the same time, the transmission member 152 also drives the operation of the ejecting unit 3 through the belt 154. The pulley 153 then drives the transmission gear 157 to rotate through the transmission rod 156. The transmission gear 157 drives the eccentric crankshaft 158 to rotate. One end of the connecting rod 159 is sleeved on the bent section of the eccentric crankshaft 158, and the other end of the connecting rod 159 is movably connected to the upper end of the drive slider 14. Since the drive slider 14 can only move up and down, the rotation of the eccentric crankshaft 158 can only drive the end of the connecting rod 159 connected to the drive slider 14 to perform up and down linear displacement, thereby driving the up and down movement of the drive slider 14. The clutch 155 can indirectly control the up and down displacement frequency of the drive slider 14 by controlling the rotation speed of the transmission rod 156.

[0043] As Figure 1 and Figure 2As shown, the mold unit 2 includes an upper mold 21 and a lower mold 22. Two through holes leading from the front end to the rear end are provided on the upper mold 21. The upper mold 21 is connected in an inserting manner via the two through holes and two positioning columns 17 of the transmission slider 14. The front end face of the upper mold 21 is in contact with one end face of the latch 16. The lower mold 22 is placed on the workbench 12, and a through hole is also provided at the central axis of the mold cavity of the lower mold 22.

[0044] The upper mold 21 is connected to the positioning column 17 of the transmission slider 14 through the through hole, and then the upper mold 21 is locked by passing the latch 16 through the positioning column 17, which reduces the time for installing and replacing the upper mold 21 and improves the efficiency.

[0045] As Figure 5 shown, the workbench 12 includes a bottom plate 121, rollers 122 and a slideway 123. The rollers 122 are rotatably connected to the bottom plate 121. The lower mold 22 is placed on the rollers 122. The slideway 123 passes through the bottom plate 121. The upper end face of the slideway 123 is lower than the upper end face of the rollers 122. The central axis of the slideway 123 coincides with the central axis of the mold cavity of the lower mold 22.

[0046] The slideway 123 is slidably connected to the ejecting unit 3, so that one end of the ejecting unit 3 can only move up and down along the slideway 123. The rollers 122 are provided to facilitate the installation and replacement of the mold unit 2, reduce the time required for replacing the mold unit 2, and improve the efficiency.

The other end of the connecting rod 32 passes through the external planet gear 33 and is fixedly connected to the counterweight 35. The central axis of the connecting rod 32 is collinear with the central axis of the external planet gear 33. The connecting rod 32 is rotatably connected to the external planet gear 33. The external planet gear 33 is provided with an internal tooth profile. The internal planet gear 34 is provided with an external tooth profile. The internal planet gear 34 meshes with the external planet gear 33. The center of gravity of the counterweight 35 and the center of the internal planet gear 34 are located on both sides of the axis of the external planet gear 33. One end of the counterweight 35 passes through the internal planet gear 34 and is rotatably connected to one end of the connecting block 36. The counterweight 35 passes through the internal planet gear 34 from the central axis of the internal planet gear 34. One end of the connecting block 36 is rotatably connected to one end of the ejector rod 37. The other end of the ejector rod 37 is inserted into the slideway 123 at the bottom end of the workbench 12 and the through hole of the lower mold 22. The ejector rod 37 is slidably connected to the slideway 123 of the workbench 12. The ejector rod 37 is slidably connected to the lower mold 22. The upper end surface of the ejector rod 37 is flush with the bottom surface of the mold cavity of the lower mold 22 when in the lowest position. The upper mold 21 and the lower mold 22 are closed.

[0048] The outer diameter of the internal planet gear 34 is half of the inner diameter of the external planet gear 33. The central axis of the connection between the ejector rod 37 and the connecting block 36 falls on the pitch circle of the internal planet gear 34.

[0049] The outer diameter of the internal planet gear 34 is half of the inner diameter of the external planet gear 33. The central axis of the connection between the ejector rod 37 and the connecting block 36 falls on the pitch circle of the internal planet gear 34. The top end of the ejector rod 37 is inserted into the slideway 123 of the workbench 12, enabling the two ends of the ejector rod 37 to perform reciprocating linear motion up and down. At the same time, a counterweight 35 for balancing the center of gravity is provided, greatly reducing the overall vibration amplitude of the ejector unit 3. In addition, setting the ejector unit 3 can help the workpiece be demolded in time and prevent the workpiece from sticking to the mold unit 2.

[0050] As Figure 4 shown in the figure, the conveying unit 4 includes two bases 41, two conveying sliders 42, two mechanical claws 43 and a connecting plate 44. The connecting plate 44 is fixedly connected to the housing 11. One of the bases 41 is fixedly connected to the connecting plate 44, and the other base 41 is fixedly connected to the housing 11. Both of the opposite surfaces of the two bases 41 are provided with chutes. The two conveying sliders 42 are respectively slidably connected to the two bases 41. The positions of the two conveying sliders 42 on the two bases 41 correspond to each other. The two mechanical claws 43 are respectively slidably connected to the two conveying sliders 42. The two mechanical claws 43 face each other.

[0051] The conveying slider 42 slides on the base 41 , and the mechanical claws 43 are slidably connected to the conveying slider 42 , which ensures that the mechanical claws 43 can be displaced in two directions, and at the same time, the two mechanical claws 43 can clamp the workpiece toward each other.

[0052] like Figure 4 As shown, the spray unit 5 includes a storage box 51 and a spray head 52, the storage box 51 is located inside the housing 11, the two spray heads 52 and the storage box 51 are connected by a hose, one spray head 52 is fixedly connected to the upper end surface of the mechanical claw 43, and one spray head 52 faces the model cavity of the upper mold 21, and the other spray head 52 is fixedly connected to the lower end surface of the mechanical claw 43, and the other spray head 52 faces the model cavity of the lower mold 22.

[0053] The storage box 51 contains a release agent, and the nozzle 52 is responsible for spraying the release agent into the mold cavity of the mold unit 2. Spraying the release agent helps the workpiece after die forging to separate from the mold cavity and prevents the workpiece and the mold unit 2 from sticking to each other and causing equipment operation failure.

[0054] Working principle of the present invention: When the present invention is working, the rotating motor 151 is started to drive the transmission member 152 to rotate, the transmission member 152 drives the pulley 153 to rotate through the belt 154, the pulley 153 then drives the transmission gear 157 to rotate through the transmission rod 156, the transmission gear 157 drives the eccentric crankshaft 158 to rotate, one end of the connecting rod 159 is sleeved on the bending section of the eccentric crankshaft 158, and the other end of the connecting rod 159 is movably connected to the upper end of the transmission slider 14. Since the transmission slider 14 is slidably connected to the fixed plates 13 on both sides of the housing 11, it can only move up and down, and the eccentric crankshaft 158 rotates. The movement can only drive one end of the connecting rod 159 connected to the transmission slider 14 to perform linear displacement up and down, thereby driving the transmission slider 14 to move up and down. The clutch 155 can indirectly control the frequency of die forging by controlling the rotation speed of the transmission rod 156. During die forging, the transmission slider 14 and the push rod 37 rise and fall at the same time. At the end of one die forging, along with the rise of the transmission slider 14, the push rod 37 lifts the die-forged workpiece, and the mechanical claw 43 clamps it for transportation. When the mechanical claw 43 clamps it, the nozzle 52 sprays a release agent into the model cavity of the upper mold 21 and the lower mold 22 to prepare for the next die forging.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
