Description

Technical Field

[0001] The invention relates to the field of forging, and in particular to a forging production system. Background Art

[0002] Forging is a metal processing process that applies pressure on the surface of the material to cause it to undergo plastic deformation in order to change its shape and properties. A forging press is a common tool for forging. It generally includes a fuselage, a lifting shaft arranged on the fuselage, and a die. The lifting shaft is driven by a driving device in the fuselage to perform lifting and lowering movements. For small forgings, after the workpiece is heated, one-time forging and forming can be achieved through the die. The die here includes an upper die and a lower die. The upper die is fixed at the end of the lifting shaft, and the lower die is fixed on the forging platform. During the lifting process of the lifting shaft, when the upper die rises to the highest position, the upper die is in the blank changing position. At this time, it is necessary to take out the forged forging and place the next workpiece in the forging press. Generally, after the workpiece is heated to a sufficient temperature, it is transported to the forging press by a manipulator for forging. That is to say, the device for heating the workpiece is in one place, and the forging is in another place. In addition, a manipulator is required for transportation, which takes up a lot of factory space, resulting in low space utilization.

[0003] For example, in the patent with application number CN202210682752.5 and patent name "A highly stable positioning and fixing device for a forging machine", it includes a metal column, a limit locking part, a pressing control device, a support fixing plate, a support column and a support fixing seat. The support fixing seat is fixedly installed in the middle of the support fixing plate, and the support column is evenly fixedly installed on the upper ends of the support fixing plate and the support fixing seat. In this patent, the slender metal column can remain stable during the extrusion deformation process, but for forgings that require hot forging, they still need to be heated and then transported to the device disclosed in the patent by a robot, so the above-mentioned technical problems cannot be solved.

[0071] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0072] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0073] In a first aspect of the present invention, a forging production system is provided, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, including:

[0074] A forging machine comprises a forging platform, a plurality of legs 5 arranged on the forging platform, and a body fixed on the top of the legs 5, wherein a lifting shaft which can be raised and lowered is arranged at the bottom of the body;

[0075] An upper mold 1 is arranged at the bottom end of the lifting shaft;

[0076] A lower die 2 is arranged directly below the upper die 1, the lower die 2 matches the upper die 1, and the lower die 2 is fixed on the forging platform. When the upper die 1 is in the blank changing position, a blank changing space is formed between the lower end surface of the upper die 1 and the upper end surface of the lower die 2;

[0077] The system also includes:

[0078] A heating coil 4 can be powered to generate heat, and a receiving groove 3 for receiving the heating coil 4 is provided on the upper end surface of the lower mold 2;

[0079] A lifting part for driving the heating coil 4 to perform lifting motion;

[0080] A fixing part is used to fix the cylindrical workpiece in the blank changing space and make the cylindrical workpiece in a vertical state.

[0081] In the present embodiment, small forgings are targeted, and the workpiece to be forged is usually a cylindrical workpiece (collectively referred to as a cylindrical workpiece in the subsequent description). The characteristics of such workpieces are small diameter, relatively long length, and small mass, and general staff can lift them easily. When the upper mold 1 is in the highest position, that is, the blank changing position, the cylindrical workpiece is manually placed in the blank changing space, and then the fixing part is started to fix the cylindrical workpiece in the blank changing space and make it vertical. At this time, the cylindrical workpiece is located directly above the heating coil 4. After completion, the lifting part is started, so that the heating coil 4 is first separated from the storage groove 3 to avoid excessive heating of the lower mold 2 and deformation after the heating coil 4 is powered on and generates heat. Then the heating coil 4 is powered on to generate heat, and the lifting part drives the heating coil 4 to do lifting and lowering movements, so that the cylindrical workpiece is continuously heated and finally heated to a sufficiently high temperature. Then the heating coil 4 is powered off and moves back into the storage groove 3. After being heated, the cylindrical workpiece is still fixed in the blank changing space by the fixing part, that is to say, the cylindrical workpiece is in a suspended state. At this time, the lifting shaft drives the upper mold 1 to move downward. After the bottom of the mold cavity of the upper mold 1 contacts the top of the cylindrical workpiece, the upper mold 1 will continue to apply pressure to the cylindrical workpiece. Since the fixing force of the fixing part on the cylinder is limited, after the pressure applied by the upper mold 1 on the cylindrical workpiece is large enough, the cylindrical workpiece will be driven to move downward. When the bottom of the cylindrical workpiece contacts the bottom of the mold cavity of the lower mold 2, the fixing part completely releases the cylindrical workpiece. At this time, the upper mold 1 continues to move downward and cooperates with the lower mold 2 to complete the forging operation. After the forging is completed, the upper mold 1 moves to the blank changing position, and then the operator uses the clamp to remove the forging from the lower mold 2, and a forging process is completed. Through this device, the heating coil 4 can be integrated into the forging machine, which can effectively reduce the occupied space and improve the space utilization.

[0082] As an implementation method, Figure 1 As shown, there is a heat buffer area above the lower mold 2. When the fixing part fixes the cylindrical workpiece in the blank changing space, the cylindrical workpiece is located above the heat buffer area, and the height of the heat buffer area is greater than the height of the heating coil 4.

[0083] In this embodiment, after the heating coil 4 heats the cylindrical workpiece to a sufficient temperature, the heating coil 4 is powered off and first moves to the heat buffer area, so that the temperature of the heating coil 4 gradually decreases. When the bottom of the cylindrical workpiece contacts the bottom of the mold cavity of the lower mold 2, the heating coil 4 moves back into the receiving groove 3. At this time, the temperature of the heating coil 4 has dropped a lot, and the impact on the lower mold 2 can be minimized.

[0084] Here, a structure of a lifting part is introduced, such as Figure 1 , Figure 3 As shown, the lifting part includes:

[0085] A first motor 7 provided on the forging platform;

[0086] A connecting block 8 and a screw rod 9 having one end connected to the output shaft of the first motor 7, the connecting block 8 is arranged on one side of the heating coil 4, and the connecting block 8 is provided with screw holes 10 penetrating the upper and lower ends thereof, the screw rod 9 is threadedly connected to the screw holes 10, and the top end of the screw rod 9 is rotatably connected to the lower end surface of the fuselage;

[0087] A guide rod is arranged between the machine body and the forging platform, and the guide rod is slidably connected to a guide hole arranged on the connecting block 8.

[0088] In this embodiment, when the first motor 7 is started, the heating coil 4 can be driven to move upward or downward through the screw rod 9 .

[0089] As an implementation method, Figure 1 , Figure 4 , Figure 7 As shown, the fixing portion includes a plurality of fixing components arranged in a vertical direction, and the fixing components include:

[0090] A plurality of horizontal linkage members distributed around the central axis of the lifting shaft;

[0091] A fixed plate 43 is arranged at the front end of the horizontal linkage member, and the fixed plate 43 is located in the blank changing space;

[0092] The system also includes a driving unit for driving the fixed plate 43 to move in the horizontal direction through a horizontal linkage, and the movement path of the fixed plate 43 passes through the central axis of the lifting shaft.

[0093] In this embodiment, a plurality of horizontal linkage members are preferably distributed in a circular array around the central axis of the lifting shaft. When the staff places the cylindrical workpiece in the blank exchange space, they can visually check that the cylindrical workpiece is roughly in the center of the blank exchange space and is roughly in a vertical state. Then the driving part causes the horizontal linkage members in each fixing assembly to drive the fixing plate 43 to move in the direction of the cylindrical workpiece, and finally the cylindrical workpiece is fixed by the fixing plate 43 in the fixing assembly. At this time, the fixing plate 43 applies pressure to the side surface of the cylindrical workpiece, so that friction is generated between the fixing plate 43 and the side surface of the cylindrical workpiece to keep the cylindrical workpiece stable. When the energized heating coil 4 starts When heating the cylindrical workpiece, the heating coil 4 will make a lifting motion. When the heating coil 4 is about to contact and interfere with the horizontal linkage in one of the fixed components, the driving unit drives the horizontal linkage in the fixed component to move toward the outside of the cylindrical workpiece, so that the corresponding fixed plate 43 releases the cylindrical workpiece and finally moves away from the cylindrical workpiece to ensure that the heating coil 4 can pass smoothly. At this time, the fixed plates 43 in other fixed components still maintain the state of fixing the cylindrical workpiece, so the cylindrical workpiece can still remain stable. After the heating coil 4 passes, the driving unit uses the horizontal linkage in the fixed component to make the corresponding fixed plate 43 fix the cylindrical fixed part again.

[0094] As an implementation method, Figure 1 , Figure 2 , Figure 4 , Figure 7 , Fig.12 , Fig.13 As shown, each leg 5 is provided with a horizontal linkage member in the fixed assembly, and the horizontal linkage member includes:

[0095] The chain 56 and the assembly block 15 with an end groove on the upper end surface are pushed, and the end groove runs through the front and rear sides of the assembly block 15; in the chain 56, each link is provided with a assembly block 15, and the two chain plates 16 on the link are fixed on the inner wall corresponding to the end groove; in the upper surface of the adjacent assembly block 15, the opposite corners are provided with an avoidance groove 18, and the avoidance groove 18 includes an arc groove, and the central axis of the pin 17 in the chain link is collinear with the central axis of the corresponding arc groove;

[0096] A first sprocket 13 meshed with the push chain 56, an inner cavity 12 and a vertical chain hole 6 are provided inside the leg 5, a first wheel shaft 14 is fixed at the center of both ends of the first sprocket 13, the first wheel shaft 14 is rotatably connected to the side wall of the inner cavity 12, and a horizontal chain groove 11 is provided on the side of the leg 5 facing the blank changing space;

[0097] The push chain 56 passes through the first sprocket 13 and turns, and a part of it is located in the chain hole 6 to become the remaining chain. Here, the end face of the assembly block 15 facing away from the end groove is an arc-shaped end face to ensure that the assembly block 15 can smoothly enter the chain hole 6; the other part passes through the chain groove 11 and enters the blank exchange space to become an extended chain. The extended chain is in a horizontal state under the mutual restriction of the assembly blocks 15 thereon; the fixed plate 43 is arranged at the end of the extended chain located in the blank exchange space;

[0098] When the driving unit drives the first sprocket 13 to rotate, the length of the extension chain changes.

[0099] In this embodiment, the structure of the horizontal linkage is introduced. When the driving unit drives the first sprocket 13 to rotate, the first sprocket 13 will drive the push chain 56 to move. At this time, the length of the extension chain can change. Due to the action of gravity, the extension chain will have a tendency to sag. When the opposite sides of the adjacent combination blocks 15 contact each other, the movement of the chain links is restricted. In addition, the chain groove 11 is horizontal. Therefore, the extension chain in the blank exchange space will be in a horizontal state. When the fixed plate 43 is against the outer side of the cylindrical workpiece, the fixed plate 43 applies pressure to the outer side of the cylindrical workpiece. Due to the action of gravity, the cylindrical workpiece also has a tendency to sag downward. The movement trend can ensure the stability of the extension chain in the horizontal state. When the heating coil 4 heats the cylindrical workpiece to a sufficiently high temperature, the lifting shaft will drive the upper mold 1 to move downward. After the bottom of the mold cavity of the upper mold 1 contacts the top of the cylindrical workpiece, the upper mold 1 will continue to apply pressure to the cylindrical workpiece. When the pressure is greater than the friction force of the fixed plate 43 on the surface of the cylindrical workpiece, the cylindrical workpiece will be driven to move downward. When the bottom of the cylindrical workpiece contacts the bottom of the mold cavity of the lower mold 2, the driving part makes the fixed plate 43 completely release the cylindrical workpiece. At this time, the upper mold 1 continues to move downward and cooperates with the lower mold 2 to complete the forging operation.

[0100] Preferably, Figure 1 , Figure 4 As shown, two fixing assemblies are provided to fix the cylindrical workpiece in the blank changing space. When the heating coil 4 is making the lifting movement and is about to interfere with the extension chain in one of the fixing assemblies, the driving part drives the pushing chain 56 to shrink into the chain hole 6 to avoid the heating coil 4, and after the heating coil 4 is away from the extension chain, drives the extension chain to move in the direction of the cylindrical workpiece to fix the cylindrical workpiece again.

[0101] Here, a structure of a driving part is introduced, such as Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.11As shown, the driving unit includes:

[0102] A second axle 21 fixedly connected to the first axle 14, wherein the central axis of the second axle 21 coincides with the central axis of the first axle 14, and one end of the second axle 21 extends to the outside of the leg 5;

The specific process is as follows: before the cylindrical workpiece is placed in the blank changing space, the adjustment component makes the linkage chain 19 and the two second sprockets 20 remain in a meshing state. When the staff puts the cylindrical workpiece into the blank changing space, the rotating component drives the third sprocket 24 to rotate, thereby driving the two second sprockets 20 on the corresponding support leg 5 to rotate through the linkage chain 19, and then driving the first sprocket 13 to rotate, so that the extension chain extends into the blank changing space, and finally fixes the cylindrical workpiece through the fixed plate 43, and the rotating component stops driving at this time. When the heating coil 4 starts to heat the cylindrical workpiece, the heating coil 4 will first approach the extension chain located below. At this time, the adjustment component corresponding to the fixed component located below makes the two adjustment blocks 35 approach each other and compress the corresponding adjustment chain. At the same time, the adjustment component corresponding to the fixed component located above makes the two adjustment blocks separate from each other, so that the corresponding adjustment chain will expand outward, and finally the second sprocket 20 located above will be separated from the linkage chain 19. In addition, before the second sprocket 20 located above is separated from the linkage chain 19, the fixed component located above will fix the push chain 56 located above in the chain groove 11, ensuring that the fixed component located above can stably fix the cylindrical workpiece. After the second sprocket 20 located above is separated from the linkage chain 19, the rotating component is started again. At this time, the linkage chain 19 will only drive the second sprocket 20 located below to rotate, thereby causing the push chain 56 to shrink, and finally causing the fixed plate 43 to move away from the cylindrical workpiece, so that the heating coil 4 passes normally. After the heating coil 4 passes, the rotating component causes the fixed plate 43 located below to fix the cylindrical workpiece again. When the heating coil 4 approaches the upper extension chain, the adjusting assembly corresponding to the upper fixed assembly makes the two adjusting blocks 35 approach each other and compresses the corresponding adjusting chain. At the same time, the adjusting assembly corresponding to the lower fixed assembly makes the two adjusting blocks separate from each other, so that the corresponding adjusting chain will expand outward, and finally the second sprocket 20 at the bottom will separate from the linkage chain 19. In addition, before the second sprocket 20 at the bottom separates from the linkage chain 19, the lower fixed assembly will fix the push chain 56 at the bottom in the chain slot 11, ensuring that the lower fixed assembly can stably fix the cylindrical workpiece. After the second sprocket 20 at the bottom separates from the linkage chain 19, the rotating assembly is started again. At this time, the linkage chain 19 will only drive the second sprocket 20 at the top to rotate, so that the push chain 56 shrinks, and finally the fixed plate 43 is away from the cylindrical workpiece, so that the heating coil 4 passes normally. After the heating coil 4 passes, the rotating assembly makes the upper fixed plate 43 fix the cylindrical workpiece again.At this time, the heating coil 4 heats the cylindrical workpiece from bottom to top, and can heat the cylindrical space from top to bottom again. When the heating coil 4 moves from top to bottom, the above method is also used to enable the heating coil 4 to move smoothly. After the heating coil 4 moves to the bottom of the cylindrical workpiece, the cylindrical workpiece is heated to a sufficiently high temperature. At this time, the component can be adjusted so that the linkage chain 19 and the two second sprockets 20 remain in a meshing state. After the bottom of the cylindrical workpiece contacts the bottom of the mold cavity of the lower mold 2, the fixed plate 43 is moved away from the cylindrical workpiece and restored to its original position by rotating the component.

[0114] As an implementation method, Figure 1 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown, the regulating components include:

[0115] A first spring 55 is located in the adjustment slot 33, one end of the first spring 55 is fixedly connected to one of the adjustment blocks 35, and the other end of the first spring 55 is fixedly connected to the other adjustment block 35;

[0116] The adjusting frame 22 corresponding to the adjusting plate 26 includes a side plate and a driving plate. The side plate is provided with a slider 40, and the slider 40 is slidably connected with the side groove 39 provided on the leg 5. The driving plate is provided with a driving groove 23 penetrating the inner and outer sides thereof. The side walls on both sides of the driving groove 23 are inclined side walls, and the inclined side walls are in contact with one of the side surfaces of the corresponding adjusting block 35.

[0117] A rack plate 54 is provided on the side plate, and a spur rack is provided on the rack plate 54;

[0118] The second motor 41 is arranged on the leg 5 and the driving gear 42 is fixed on the output shaft of the second motor 41. On the same leg 5, the rack plates 54 on the two side plates are located on different sides of the driving gear 42, and the driving gear 42 is meshed with the spur rack.

[0119] In this embodiment, when the second sprocket 20 is separated from the linkage chain 19, the corresponding first spring 55 will be in a natural state. Before the cylindrical workpiece is placed in the blank exchange space, the position of the adjustment frame 22 at this time makes the linkage chain 19 and the two second sprockets 20 remain in meshing state. Here is an example, when only the lower second sprocket 20 needs to be meshed with the linkage chain 19, the second motor 41 is started, and the lower adjustment frame 22 moves upward and the upper adjustment frame 22 moves downward through the driving gear 42, so that the two adjustment blocks 35 in the lower adjustment plate 26 will compress the first spring 55 and move closer to each other, so that the fourth sprocket 37 moves closer to each other, and at the same time, the two adjustment blocks 35 in the upper adjustment plate 26 will move away from each other under the elastic force of the first spring 55, so that the fourth sprocket 37 moves away from each other, and finally the upper linkage chain 19 is separated from the second sprocket 20. At this time, when the linkage chain 19 moves, it will only drive the lower second sprocket 20 to rotate.

[0120] As an implementation method, Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown, the fixing assembly includes:

[0121] A connecting rod 32 fixedly connected to the driving plate, the connecting rod 32 being slidably connected to a through slot 31 provided on a side of the supporting leg 5;

[0122] A movable plate 29 fixedly connected to the connecting rod 32, the movable plate 29 is slidably connected to a pressure chamber 27 provided inside the support leg 5, the pressure chamber 27 is communicated with the chain groove 11, and the pressure chamber 27 is located above the chain groove 11;

[0123] A pressing plate 28 is located below the movable plate 29, and the pressing plate 28 is slidably connected to the pressing chamber 27;

[0124] One end of the second spring 30 is fixedly connected to the movable plate 29 , and the other end of the second spring 30 is fixedly connected to the pressure plate 28 .

[0125] In this embodiment, when the linkage chain 19 is engaged with the corresponding two second sprockets 20 at the same time, the pressure plate 28 will apply a certain pressure to the pin 17 in the push chain 56 through the second spring 30, but the pressure at this time will not affect the movement of the push chain 56. The above example is used to illustrate the working process of the fixing component. When only the lower second sprocket 20 needs to be engaged with the linkage chain 19, the second motor 41 is started, and the driving gear 42 is used to make the adjustment frame 22 located below move upward, and the adjustment frame 22 located above move downward, and finally the linkage chain 19 located above is separated from the second sprocket 20. At this time, when the linkage chain 19 moves, it will only drive the second sprocket 20 located below to rotate. When the adjusting frame 22 located at the bottom moves upward and the adjusting frame 22 located at the top moves downward, in the fixed assembly located at the bottom, the adjusting frame 22 located at the bottom will drive the movable plate 29 to move upward, so that the pressure between the pressure plate 28 and the corresponding pin shaft 17 in the pushing chain 56 becomes smaller and smaller. At the same time, in the fixed assembly located at the top, the adjusting frame 22 located at the top will drive the movable plate 29 to move downward, so that the pressure between the pressure plate 28 and the corresponding pin shaft 17 in the pushing chain 56 becomes larger and larger. Finally, when the second sprocket 20 located at the bottom is separated from the linkage chain 19, the pressure between the pressure plate 28 located at the bottom and the corresponding pin shaft 17 in the pushing chain 56 is large enough to fix the position of the pushing chain 56.

[0126] As an implementation method, Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the rotating assembly includes:

[0127] A support column 49 and a ring 45 with a surface annular groove 50, wherein a plurality of support columns 49 are provided, and one end of the support column 49 is fixed to the lower end surface of the fuselage, and the other end of the support column 49 is rotatably connected to the surface annular groove 50;

[0128] A third motor 47 fixed to the body and a linkage gear 48 fixed to the output shaft of the third motor 47, a side ring groove 51 is provided on the outer side of the ring 45, a ring gear 52 is provided on the inner wall of the side ring groove 51, and the linkage gear 48 meshes with the ring gear 52;

[0129] A plurality of cylindrical pins 46 are distributed in a circular array around the central axis of the circular ring 45, and one end of the cylindrical pin 46 is fixed to the upper surface of the circular ring 45; in the fixing assembly located above, the third wheel shaft 25 is provided with through holes 44 passing through both ends thereof, and the circular ring 45 passes through the through holes 44, and the inner wall of the through holes 44 is provided with a plurality of spiral grooves 53, and the spiral grooves 53 match the cylindrical pins 46. During the rotation of the circular ring 45, the cylindrical pins 46 enter into the spiral grooves 53 to drive the third wheel shaft 25 to rotate.

[0130] In this embodiment, when the third motor 47 is started, the ring 45 can be driven to rotate through the linkage gear 48. During the rotation of the ring 45, after one of the cylindrical pins 46 enters a spiral groove 53 of the third wheel shaft 25, the cylindrical pin 46 will drive the third wheel shaft 25 to rotate a certain angle while passing through the spiral groove 53. Since the number of cylindrical pins 46 is sufficient, after the cylindrical pin 46 enters a spiral groove 53 of the third wheel shaft 25, the next cylindrical pin 46 will enter the next spiral groove 53, thereby ensuring the sustainable rotation of the third wheel shaft 25.
