Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of molds, in particular to a multi-directional die forging forming die for multi-flange valve body forgings and a forming process. BACKGROUND

[0002] At present, there are two forming methods for valve body forgings, namely ordinary die forging and multi-directional die forging with horizontal parting. When ordinary die forging is used, flash exists on the parting surface, and horizontal holes and vertical holes cannot be forged, the weight of the forging is large, and the material is wasted. Although the multi-directional die forging with horizontal parting can forge horizontal holes and vertical holes, it cannot forge main flanges, resulting in large weight of the parts after machining of the forgings, and difficult installation.

[0003] The multi-directional die forging forming die is an important tool for the multi-directional die forging process. The multi-directional die forging forming die usually has a complex structure design to meet the requirements of applying pressure in multiple directions for forging. The die is generally composed of multiple modules, including an upper die, a lower die, and side dies. The modules need to be accurately matched.

[0004] In the use of the multi-directional die forging forming die, the inside of the die needs to be reasonably lubricated to reduce the friction between the die and the forging, thereby reducing wear and tear and improving the service life of the die. Currently, the lubricating oil is applied to the die by manual quantitative application. However, different forging materials have different lubricant requirements. When the hardness of the forging is high, the pressure and friction that the die bears during forging will be greater. In order to reduce the friction between the die and the forging and prevent excessive wear and tear and damage to the die, the amount of lubricant sprayed needs to be increased. When the hardness of the forging is low, the friction between the die and the forging is relatively small, and the wear of the die is also relatively light. Therefore, less lubricant can meet the lubrication requirements. Excessive lubricant will cause the lubricant to accumulate between the die and the forging, affecting the size accuracy and surface quality of the forging. Therefore, the current quantitative lubricant application method is not only time-consuming and labor-intensive, but also can affect the die forging forming quality of the forging due to inaccurate amount of lubricant.

[0045] The PLC controller 8 is fixedly arranged at the upper end of the base 1 and electrically connected with the mold forging mechanism 2, the lubricant spraying mechanism 3, the side spraying control mechanism 4, the forging hardness confirmation and control mechanism 5, the mold wear degree calculation warning mechanism 6 and the pressure maintaining time confirmation mechanism 7.

[0046] The operation principle of the present application is described as follows: before the die forging of the forging, the hardness of the forging is detected by using the existing hardness tester, and the detected value is used to rotate the rotating plate 56, so that the pointer 58 moves to the corresponding value position of the hardness scale plate 57; when the rotating plate 56 rotates, the connecting rod 54 and the control conductive tab 55 are driven to move in the control circular shell 51 through the rotating shaft 53, so that the control conductive tab 55 slides on the control resistance rod 52; specifically, the greater the hardness of the forging, the greater the rotating distance of the rotating plate 56, so that the control conductive tab 55 slides on the control resistance rod 52 for a greater distance, and the access resistance of the control resistance rod 52 is smaller.

[0047] The PLC controller 8 controls the electric push rod 31 to push the L-shaped supporting plate 32 to move forward, so that the two first spraying pipes 35 move to the positions corresponding to the lower die 21 and the upper die 24, and the second spraying pipe 37 moves to the position of the side die 27. The PLC controller 8 controls the motor rotating assembly 34 and the material pump 310 to work. The material pump 310 cooperates with the elastic feeding pipe 39 to convey the lubricant from the external lubricant storage tank into the rotating pipe 33, and then the lubricant is sprayed out through the first spraying pipe 35 and the second spraying pipe 37. The motor rotating assembly 34 drives the rotating pipe 33 to rotate, thereby comprehensively spraying the lubricant in the inside of the lower die 21, the upper die 24 and the side die 27, effectively improving the spraying efficiency of the lubricant. The regulating conductive tab 55 and the regulating resistance rod 52 are connected in series in the power supply circuit of the material pump 310. The material pump 310 is a direct current pump. When the hardness of the forge piece is greater, the access resistance of the regulating resistance rod 52 is smaller, and the power supply current of the material pump 310 is greater, so that the working speed of the material pump 310 is higher, thereby making the lubricant spraying amount in the inside of the die larger in unit time. On the contrary, when the hardness of the forge piece is smaller, the access resistance of the regulating resistance rod 52 is relatively larger, and the lubricant spraying amount of the die is smaller, thereby meeting different lubricant spraying requirements.

[0048] When the rotating pipe 33 rotates, the chain wheel assembly 43 drives the transmission screw 42 to rotate synchronously. Through the threaded sleeve joint action of the transmission screw 42 and the transmission seat 45, the transmission seat 45 drives the pressing round head 46 to move in the control shell 41. When the second spraying pipe 37 moves in the spraying range of the side die 27, the pressing round head 46 does not contact the control switch 44 at this time. The electromagnetic valve 38 on the extension pipe 36 is opened, thereby making the second spraying pipe 37 spray the lubricant to add the lubricant to the side die 27. When the second spraying pipe 37 moves out of the spraying range of the side die 27, the pressing round head 46 presses the control switch 44 at this time. The control switch 44 controls the electromagnetic valve 38 to be closed, so that the second spraying pipe 37 does not spray the lubricant any more. Until the second spraying pipe 37 moves into the spraying range of the side die 27 again, the pressing round head 46 moves away from the control switch 44 again. The electromagnetic valve 38 is opened again, so that the second spraying pipe 37 sprays the lubricant to add the lubricant to the side die 27.

[0049] After the lubricant spraying is completed, the PLC controller 8 controls the lubricant spraying mechanism 3 to reset. After the forge piece is placed in the lower die 21 and is relatively fixed, the PLC controller 8 controls the top forging cylinder 23 and the side forging cylinder 26 to act, thereby realizing the rapid die forging forming of the forge piece through the extrusion cooperation between the lower die 21, the upper die 24 and the side die 27.

[0050] When the die forging of a forging piece is completed, the PLC controller 8 controls the driving motor 63 to work for 3s, the driving motor 63 drives the driving screw 62 to rotate, the driving screw 62 and the trigger plate 64 are connected through threads, so that the trigger plate 64 moves in the warning shell 61 for a distance, until the trigger plate 64 presses the warning switch 65 after the die forging of the forging piece is completed for many times, the warning switch 65 controls the warning device 66 to work, reminding the staff to maintain and check the die, avoiding that the excessive wear of the die affects the die forging quality of the forging piece, and the control conductive tab 55 and the control resistance rod 52 are also connected to the power supply circuit of the driving motor 63, the driving motor 63 is a direct current motor, when the hardness of the forging piece is greater, the connected resistance of the control resistance rod 52 is smaller, at this time, the power supply current of the driving motor 63 is greater, the rotating speed of the driving motor 63 is faster, so that the driving motor 63 can drive the trigger plate 64 to move a greater distance in the warning shell 61 in 3s, and the trigger plate 64 can press the warning switch 65 after the die forging of the forging piece is completed for a smaller number of times, based on that the greater the hardness of the forging piece is, the greater the wear degree of the die is, the interval time of the warning to the staff is shortened, so that the wear degree of the die is maintained and checked more timely;

[0051] The control conductive tab 55 and the control resistance rod 52 are also connected in series to the power supply circuit of the extrusion electromagnetic plate 76, the PLC controller 8 controls the power supply equipment to supply power to the extrusion electromagnetic plate 76, the extrusion electromagnetic plate 76 generates the same magnetism as the extrusion permanent magnet plate 75, and then generates a pushing force to the stressed plate 73, so that the stressed plate 73 moves downward along the guide slide rod 72 against the elastic force of the pushing spring 74, when the hardness of the forging piece is greater, the connected resistance of the control resistance rod 52 is smaller, the power supply current of the extrusion electromagnetic plate 76 is greater, the magnetism of the extrusion electromagnetic plate 76 is stronger, a greater downward pushing force is generated to the stressed plate 73, and then the stressed plate 73 drives the in-place switch 77 to move a greater distance, so that the distance between the in-place switch 77 and the pressing plate 710 is farther, and then in the die forging of the forging piece, after the lower die 21, the upper die 24 and the side die 27 are pressed to enter the pressure maintaining time, the PLC controller 8 controls the servo motor 79 to work synchronously, the servo motor 79 drives the rotating screw 78 to rotate, the rotating screw 78 and the pressing plate 710 are connected through threads, so that the pressing plate 710 gradually moves in the confirmation shell 71, until the pressing plate 710 presses the in-place switch 77, indicating that the pressure maintaining work of the forging piece after the die forging is completed, the greater the hardness of the forging piece is, the longer the pressure maintaining time is, and the die forging quality of the forging piece is ensured.

[0052] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
