Description

Technical Field

[0001] The invention relates to the technical field of forged steel valve forming, and in particular to a forged steel valve forming process. Background Art

[0002] The forming process of forged steel valves is a precise manufacturing process, which is mainly used to produce valves with high strength and good sealing performance. Forged steel valves are usually suitable for environments with high pressure, high temperature or special media requirements. Forged steel valves are usually made of carbon steel, alloy steel or stainless steel and other materials. They need to be heated to an appropriate temperature before forging. The heated metal billet is forged on a press or forging hammer, and the pressure on the die or anvil causes it to deform into the required shape and size. After forming, the excess flash is cut off to produce qualified forgings.

[0003] After completing the flash removal work, the forged steel valve and the removed flash need to be removed separately by manual or special manipulators so that the forged steel valve can be processed later and the removed flash can be recycled. In the prior art, two groups of manipulators are usually set up to transfer the flash and the forged steel valve respectively, which is costly. After the flash is collected, metal debris caused by flash removal will often be generated on the trimming die. If it is not cleaned in time, it will be squeezed between other forged steel valves during the subsequent flash removal process, causing indentations on the surface of the forged steel valve, affecting the product quality of other forged steel valves.

[0049] like Figure 1 As shown, an embodiment of the present invention provides a forged steel valve forming process, comprising the following steps:

[0050] S1. Pretreatment: peel the whole round steel bar through peeling equipment to prevent micro crack defects in forgings;

[0051] S2, cutting and heating, cutting the round steel bar into segments on a sawing machine according to the material cutting requirements in the process card, placing the cut bar into a heating furnace and setting parameters to heat it to the ideal temperature;

[0055] The flash removal equipment is used to remove the flash during the forming process of forged steel valves, and push the flash and forged steel valves to different areas for subsequent processing.

[0056] In this embodiment, if Figures 2 to 13 As shown, the flash removal equipment includes a trimming base 1 and a punch base plate 4, the top of the punch base plate 4 is fixedly connected to the die base plate 2, the top of the die base plate 2 is provided with a trimming opening 3, the trimming opening 3 is provided with evenly distributed trimming dies 13, the punch base plate 4 is located above the trimming base 1, and the bottom end of the punch base plate 4 is fixedly connected to a trimming punch 5, the trimming base 1 provides support for the die base plate 2, the punch base plate 4 provides a mounting and fixing position for the trimming punch 5, the punch base plate 4 is associated with the driving shaft of the press, the trimming die 13 provided on the trimming opening 3 is used to place the forged steel valve waiting for trimming, the punch base plate 4 can drive the trimming punch 5 to press down under the action of the press, and cooperate with the trimming die 13 in the trimming opening 3 to cut the flash on the forged steel valve, the trimming opening 3, the punch base plate 4 The principles and usage methods of the base plate 4 and the trimming punch 5 are the same as those in the prior art and will not be elaborated herein. The outer side of the trimming base 1 is movably connected to a movable plate 6 through a rotating rod, and a positioning groove 12 matching the shape of the movable plate 6 is provided on the outer side of the trimming base 1. A storage box 7 is fixedly connected to the outer side of the movable plate 6. An electric telescopic rod 9 is symmetrically installed on the top of the storage box 7. A mounting seat 10 is sleeved at the end of the driving shaft of the electric telescopic rod 9, and a movable seat 19 is sleeved at the bottom end of the mounting seat 10. During operation, the electric telescopic rod 9 can drive the mounting seat 10 and the movable seat 19 to move, and push the forged steel valve and the flash, so that the separated forged steel valve and the flash can be pushed down from different positions on the die base plate 2 for separation, which is convenient for the subsequent collection and processing of the forged steel valve and the recycling of the flash.

[0057] The first pushing component is used to assist the movable seat 19 in pushing the forged steel valve after the flash is cut off, and the first pushing component is connected to the movable seat 19; the second pushing component is used to assist the movable seat 19; the cleaning component is used to clean the residual metal debris on the cutting edge 3, and the cleaning component is connected to the storage box 7. In the process of the electric telescopic rod 9 driving the mounting seat 10 and the movable seat 19 to perform telescopic activities, the first pushing component works to contact the forged steel valve to push the forged steel valve during the extension of the electric telescopic rod 9, and the mounting seat 10 and the locking block 11 are in a first matching state. In the process of the retraction of the electric telescopic rod 9, the second pushing component works to contact the cut flash to push the flash. At the same time, the cleaning component cleans the cutting edge 3, and the mounting seat 10 and the movable seat 19 are in a second matching state. While the flash is recovered, the residual debris at the cutting edge 3 is cleaned synchronously.

[0058] In this embodiment, if Figures 2 to 6 As shown, an ejection hole 14 is opened in the trimming die 13, and an ejector structure corresponding to the position of the ejector hole 14 is arranged on the inner side of the trimming base 1. After the flash removal work is completed, the ejector structure in the trimming base 1 can eject the forged steel valve after the flash removal in the trimming die 13, so that the position of the forged steel valve can correspond to the position of the first pushing assembly on the mounting seat 10 and the movable seat 19 in the first state, ensuring that the first pushing assembly can push the forged steel valve when working. One end of the movable plate 6 is movably connected to the outside of the trimming base 1 through a rotating rod. The movable plate 6 is used to maintain the relative position between the storage box 7 and the trimming base 1, and can drive the storage box 7 to deflect around the rotating rod. The trimming base 1 is provided with a locking block 11 corresponding to the position of the other end of the movable plate 6, and the trimming base 1 is provided with a first movable cavity 16 adapted to the shape of the locking block 11. A spring 17 is fixedly connected between the locking block 11 and the first movable cavity 16. A locking port 18 adapted to the shape of the locking block 11 is provided on the movable plate 6. When the cut flash needs to be accessed through the storage box 7, the locking block 11 passes through the locking port 18 on the movable plate 6 under the action of the elastic force of the spring 17. In the process, the movable plate 6 is in a locked state, and the storage box 7 is kept parallel to the side of the die bottom plate 2, so that the flash that slides down from the side of the die bottom plate 2 can be received. When the flash stored in the storage box 7 needs to be collected, the electric telescopic rod 9 is in a retracted state to avoid collision between the mounting seat 10 and the movable seat 19 and the die bottom plate 2 during the deflection of the movable plate 6 and the storage box 7. The locking block 11 is moved to make the locking block 11 withdraw from the locking port 18 to release the lock of the movable plate 6. The movable plate 6 and the storage box 7 can deflect the rotating rod under the action of their own gravity until the end of the movable plate 6 away from the rotating rod is embedded in the positioning groove 12, so that the storage box 7 is tilted, and the flash stored therein is poured out, which is easy to collect the flash in a concentrated manner.

[0059] In this embodiment, if Figures 6 to 9 As shown, the first pushing assembly includes a first push plate 21 fixedly connected to the movable seat 19, and the first push plate 21 is provided with evenly distributed limiting grooves 31 corresponding to the positions of the trimming die 13. The shapes of the trimming die 13 and the limiting grooves 31 are both adapted to the external shape of the forged steel valve. A guiding surface 22 is provided at the end of the first push plate 21. During the extension of the electric telescopic rod 9, the mounting seat 10 and the movable seat 19 follow the displacement of the electric telescopic rod 9 to push the forged steel valve and discharge the forged steel valve from the side of the die bottom plate 2 away from the storage box 7. The mounting seat 10 and the movable seat 19 are in a first matching state, and a certain gap is left between the bottom end of the guiding end 23 and the top of the trimming passage 3 to prevent the guiding end 23 from driving the cut flash to move during the operation of the first pushing assembly. , while pushing the forged steel valve to move, it also drives the flash to move, resulting in the mixed transfer of the flash and the forged steel valve. The position of the first push plate 21 corresponds to the position of the lifted forged steel valve. The guide surface 22 on the first push plate 21 makes the end area of ​​the first push plate 21 smaller, making it easier to insert into the gap between the forged steel valve and the trimming opening 3, so that the forged steel valve can enter the limiting groove 31 on the first push plate 21, so that the limiting groove 31 and the outside of the forged steel valve are in close contact. Since the shape of the limiting groove 31 is compatible with the external shape of the forged steel valve, a wrap is formed on the outside of the forged steel valve, and then in the process of the first pushing component pushing the forged steel valve to move, the position of the forged steel valve is kept stable to prevent the forged steel valve from being misplaced and sliding to other positions on the trimming opening 3, and then failing to output from the correct position.

[0060] The second pushing assembly includes a second pushing plate 20 fixedly connected to the movable seat 19, and the second pushing plate 20 and the first pushing plate 21 are symmetrically distributed on both sides of the movable seat 19. The second pushing plate 20 is located on a side of the movable seat 19 close to the electric telescopic rod 9, and the first pushing plate 21 is located on a side of the movable seat 19 away from the electric telescopic rod 9. During the retraction of the electric telescopic rod 9, the cleaning assembly works synchronously. Under the thrust of the airflow generated by the fan 8, relative sliding occurs between the movable seat 19 and the mounting seat 10, and the movable seat 19 slides downward, driving the second pushing assembly to move until the bottom end of the guide end 23 contacts the top of the trimming passage 3, and then the electric telescopic rod 9 drives the mounting seat 10 and the movable seat 19 to retract, which can drive the guide end 23 to contact the cut flash, thereby pushing the flash so that the flash can fall and be discharged from the die bottom plate 2 toward one side of the storage box 7.

[0061] The second push plate 20 is inclined toward the electric telescopic rod 9, and the end of the second push plate 20 is bent toward the electric telescopic rod 9 to form a guide end 23. A first weakening groove 24 is provided in the middle of the second push plate 20. The first weakening groove 24 is provided on a side of the second push plate 20 close to the first push plate 21. The inclination of the second push plate 20 and the setting of the guide end 23 enable the second push plate 20 and the guide end 23 to form an inclined surface with the top of the trimming passage 3 after the movable seat 19 is pressed down, so that the second push plate 20 and the guide end 23 can form an inclined surface with the top of the trimming passage 3, so that the second push plate 20 and the guide end 23 can be adjusted. 3 can shovel up the flash after contacting with the flash, ensuring the pushing and cleaning effect of the flash. The first weakened groove 24 on the second push plate 20 makes the thickness of the second push plate 20 at this location thinner and weaker, making it easier to deform after being acted upon by an external force. Then, during the process in which the movable seat 19 drives the second push plate 20 to be pressed down, after the guide end 23 contacts the top of the trimming opening 3, the second push plate 20 can be bent and deformed at the second push plate 20, ensuring the fitting effect between the bottom end of the guide end 23 and the top of the trimming opening 3.

[0062] In this embodiment, if Figures 10 to 13 As shown, the cleaning component includes a fan 8 symmetrically installed on the outside of the storage box 7, the fan 8 is connected to the mounting seat 10 through a connecting pipe 15, a connecting cavity is provided in the mounting seat 10, a second movable cavity 26 adapted to the size of the mounting seat 10 is provided in the movable seat 19, and the bottom end of the movable seat 19 is sleeved with evenly distributed nozzles 27, the fan 8 can prepare a wind beam when working, and input the airflow into the connecting cavity of the mounting seat 10 through the connecting pipe 15, the connecting cavity is connected with the second movable cavity 26 in the movable seat 19, the airflow entering the connecting cavity can promote the relative sliding between the movable seat 19 and the mounting seat 10, so that the movable seat 19 is pressed down, and the airflow can also be ejected through the nozzle 27 at the bottom of the movable seat 19, and in the process of retracting the electric telescopic rod 9, the jet cleaning of the trimming opening 3 is realized, the metal debris retained on the trimming opening 3 is swept off, and the metal debris in the trimming die 13 is discharged through the ejection hole 14.

[0063] There are evenly distributed elastic sheets 25 fixedly connected between the mounting seat 10 and the movable seat 19, and the top and bottom ends of the elastic sheets 25 are both provided with fixed ends 30. The fixed end 30 at the top is fixedly connected to the mounting seat 10 by bolts, and the fixed end 30 at the bottom is fixedly connected to the movable seat 19 by bolts. The elastic sheet 25 in the mounting seat 10 is used to limit the position between the mounting seat 10 and the movable seat 19, so that the movable seat 19 is in a first matching state with the mounting seat 10 when not affected by external force. After being affected by the airflow of the cleaning component, the movable seat 19 is in a second matching state with the mounting seat 10. At this time, the elastic sheet 25 is in a stretched state. After the cleaning component stops working, the elastic sheet 25 can be reset under the action of its own elastic force to restore the relative position of the mounting seat 10 and the movable seat 19.

[0064] The middle part of the elastic sheet 25 is a second C-shaped weakening groove 28, and the elastic sheet 25 is provided with a third C-shaped weakening groove 29 symmetrically distributed on the upper and lower sides of the elastic sheet 25. The thickness of the second weakening groove 28 and the third weakening groove 29 is less than the thickness of the elastic sheet 25, and the second weakening groove 28 and the third weakening groove 29 are provided with evenly distributed lightweight grooves. The thickness of the second weakening groove 28 and the third weakening groove 29 on the elastic sheet 25 is equivalent to other areas on the elastic sheet 25. Thinner and weaker in strength, the elastic sheet 25 is more likely to bend and deform at the second weakening groove 28 and the third weakening groove 29 after being acted upon by external force, making it easy to switch the mounting seat 10 and the movable seat 19 between the first state and the second state.

[0065] The working principle of the technical solution provided by the present invention is as follows:

[0066] When in use, the forged steel valve with flash is placed in the trimming die 13 on the trimming opening 3, and the press is started to drive the punch bottom plate 4 and the trimming punch 5 to be pressed down, and the trimming punch 5 cooperates with the trimming die 13 on the trimming opening 3 to cut off the flash on the outside of the forged steel valve. After cutting off the flash, the punch bottom plate 4 and the trimming punch 5 are reset, and the ejector structure in the trimming base 1 works, and the ejector is inserted from the bottom of the trimming opening 3 to eject the forged steel valve through the ejection hole 14.

[0067] After the forged steel valve is ejected, the electric telescopic rod 9 works and extends, and the electric telescopic rod 9 extends and drives the mounting seat 10 and the movable seat 19 to move. The first push plate 21 on the movable seat 19 contacts the outside of the forged steel valve, and the forged steel valve is guided by the guide surface 22 and embedded in the limiting groove 31. Following the movement of the movable seat 19, it is discharged and falls from the side of the die bottom plate 2 away from the storage box 7.

[0068] After that, the fan 8 starts working and prepares a wind beam. The airflow enters the mounting seat 10 through the connecting pipe 15, pushing the movable seat 19 downward. The movable seat 19 is pressed downward and drives the second push plate 20 to move until the bottom end of the guide end 23 contacts the top of the trimming opening 3. At the same time, the airflow is sprayed out through the nozzle 27 at the bottom of the movable seat 19, and the electric telescopic rod 9 retracts. The guide end 23 contacts the flash cut off on the trimming opening 3 and pushes the flash to move. At the same time, the wind beam sprayed from the nozzle 27 cleans the remaining debris on the trimming opening 3 until the electric telescopic rod 9 is completely retracted and the flash falls into the storage box 7.

[0069] When the flash in the storage box 7 needs to be taken out, the locking block 11 is moved in the area outside the trimming base 1, so that the locking block 11 is withdrawn from the locking port 18 on the movable plate 6, and the movable plate 6 is unlocked. The movable plate 6 and the storage box 7 deflect around the rotating rod under the action of their own gravity until the movable plate 6 is embedded in the positioning groove 12. The storage box 7 is tilted to pour out the accumulated flash, completing the working process of the entire flash removal device.
