Description

Technical Field

[0001] The present invention relates to the technical field of forging devices, and more specifically, to a forging device for petroleum valves and a working method thereof. Background Art

[0002] Forging device is an important equipment used for metal forming. It forms metal by applying pressure to it. The working principle of forging device mainly includes power system, transmission system, control system and auxiliary system. The power system is usually composed of electric motor, hydraulic pump or pneumatic device, which provide power for forging machine.

[0003] The forging devices for petroleum valves currently on the market usually heat the metal blank to be forged to the appropriate forging temperature, place the heated metal blank in the workpiece slot of the forging machine, adjust it to the appropriate position, and then the upper workpiece slot falls down to limit the metal blank with the lower workpiece slot, and then the punch heads on both sides punch the workpiece. The required valve shape is formed by the pressure of the punch heads on both sides. After the punching is completed, the upper workpiece slot moves up to take away the processed metal blank.

[0004] During the processing, the punch heads on both sides are in direct contact with the heated metal blank. The temperature difference between the punch heads and the metal blank is too large, which will cause the two ends of the metal blank in contact with the punch to cool down quickly. If the metal blank cools too fast during the cooling process after forging, it may generate large thermal stress and tissue stress inside the metal blank. If the stress exceeds the strength limit of the forging, it will cause smooth and long cooling cracks in the forging, causing the workpieces produced to fail to meet the standards and have quality defects. In the process of stamping the metal blank, the metal blank will splash out oxide scale and leave oxide scale in the workpiece groove. After the oxide scale accumulates, it will affect the forging of the next workpiece. Summary of the invention

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0052] See also Figure 1-13 , the present invention provides the following technical solutions:

[0053] Example 1, see Figure 1 and Figure 2 A forging device for an oil valve comprises a stamping unit 1. The stamping unit 1 can process a heated metal blank to allow the metal blank to be processed into a required oil valve shape.

[0054] See also Figure 2 The stamping unit 1 includes a stamping base 11, which is a rectangular hollow configuration. A first stamping cylinder 13 and a second stamping cylinder 14 are respectively installed on the two side walls of the stamping base 11. A first stamping column 17 is installed at the output end of the first stamping cylinder 13, and a second stamping column 18 is installed at the output end of the second stamping cylinder 14. A lower module 15 is installed at the middle position of the bottom of the stamping base 11. The lower module 15 is divided into multiple layers and can withstand the stress generated during the processing of the metal blank. The top layer of the lower module 15 can support the heated metal blank. The first stamping cylinder 13 is used to drive the first stamping column 17 to slide in the horizontal direction, and the second stamping cylinder 14 is used to drive the second stamping column 18 to move horizontally. That is, when the metal blank is placed on the lower module 15, the first stamping column 17 and the second stamping column 18 are used to approach each other, so as to form the metal blank.

[0055] See also Figure 2 A lifting cylinder 12 is installed on the top of the stamping base 11. When the metal blank is placed on the lower module 15, the output end of the lifting cylinder 12 penetrates the upper plate of the stamping base 11. An upper module 16 is installed on the output end of the lifting cylinder 12. The shape of the upper module 16 matches the lower module 15. The part of the upper module 16 connected to the lifting cylinder 12 is slidably installed on the two side walls of the stamping base 11. The output end of the lifting cylinder 12 extends out, and the side of the upper module 16 close to the metal blank matches the lower module 15 to clamp the metal blank. The part of the upper module 16 connected to the lifting cylinder 12 slides on the two side walls of the stamping base 11, which can avoid sudden falling and provide stable support.

[0056] See also Figure 3A cleaning unit 2 is installed on one side of the stamping unit 1. The cleaning unit 2 is used to clean the oxide scale remaining on the stamping end surfaces of the first stamping column 17 and the second stamping column 18. The specific structure of the cleaning unit 2 is as follows:

[0057] The cleaning unit 2 includes a spray gun 23, which is connected to an air supply device. The spray gun 23 is installed on the side of the stamping base 11 away from the temperature control unit 5. A cleaning arm 22 is installed above the spray gun 23. A cleaning base 21 is installed at the output end of the cleaning arm 22. The cleaning arm 22 can rotate on the cleaning base 21. The angle of the cleaning arm 22 is adjusted to avoid cleaning dead corners. The cleaning arm 22 adjusts the upper and lower heights and angles of the spray gun 23 to clean the oxide scale at multiple angles on the stamping unit 1 and the stamping end faces of the first stamping column 17 and the second stamping column 18.

[0058] By arranging the spray gun 23 to be installed on the cleaning arm 22, the oxide layer on the punching unit 1 can be cleaned.

[0059] Embodiment 2: Since the punch heads on both sides are in direct contact with the heated metal blank during the processing, the temperature difference between the punch head and the metal blank is too large, which will cause the two ends of the metal blank in contact with the punch to cool down quickly. If the metal blank cools too fast during the cooling process after forging, large thermal stress and tissue stress may be generated inside the metal blank. If the stress exceeds the strength limit of the forging, it will cause smooth and elongated cooling cracks in the forging, causing the produced workpiece to fail to meet the standards and have quality defects. Moreover, since the materials of the workpiece and the hot pressing head are different, their thermal expansion coefficients are different, which may cause the expansion degree of the two to be inconsistent during the heating process, thereby causing deformation or damage to the workpiece, or generating a gap between the hot pressing head and the workpiece, affecting the processing accuracy.

[0060] See also Figure 5 and Figure 6A heating unit 3 is installed on one side of the stamping unit 1. The heating unit 3 heats the stamping end faces of the first stamping column 17 and the second stamping column 18. The heating unit 3 includes a driving support base 31. The driving support base 31 is installed on one side of the middle bottom of the second stamping cylinder 14. A rotating motor 33 is installed at the top position of the driving support base 31. A rotating support frame 32 is installed on one side of the driving support base 31. The rotating support frame 32 is two raised rectangles. Circular through holes are opened on the tops of the two rotating support frames 32. A rotating shaft is rotatably installed above the two rotating support frames 32. The rotating shaft 34 is installed in the circular through hole of the above-mentioned rotating support frame 32. The rotating shaft 34 can be rotated on the rotating support frame The rotating shaft 34 is in the shape of a cylinder, and a plane is provided on the outer wall of the cylinder to facilitate the installation of the rotating shaft 34. The output end of the rotating motor 33 is connected to the rotating shaft 34, and a rotating bracket 35 is installed on the plane of the rotating shaft 34. The rotating bracket 35 is in the shape of a U-shape, and heating mechanisms 36 are installed at both ends of the U-shaped protrusion. The distance extended from both ends of the U-shaped protrusion can just reach the outer diameter of the first punching column 17 and the second punching column 18. The rotating motor 33 is used to drive the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, it can drive the rotating bracket 35 and the heating mechanism 36 to move, thereby adjusting the position of the heating mechanism 36 relative to the punching head, which is convenient for the subsequent processing of the metal blank.

[0061] The heating mechanism 36 includes a heating trough 361, which is connected to the raised end of the rotating bracket 35. A circular groove is arranged in the middle of the heating trough 361, and induction coils 362 are arranged equidistantly in the middle circular groove of the heating trough 361. A heating plate 363 is arranged at the opening position of the circular groove of the heating trough 361. The equidistantly arranged induction coils 362 can evenly heat the heating plate 363 to avoid the situation where only local heating is performed. The output end of the rotating motor 33 rotates forward, driving the rotating shaft 34 to rotate, and the rotating shaft 34 rotates synchronously to drive the rotating bracket 35 to rotate. The stamping end faces of the first stamping column 17 and the second stamping column 18 are fitted with the heating disk 363, and the induction coil 362 heats the heating disk 363 through electromagnetic induction. The heating disk 363 heats the stamping end faces of the first stamping column 17 and the second stamping column 18. When the temperature of the first stamping column 17 and the second stamping column 18 is heated to 360 degrees, the rotating motor 33 reverses to drive the heating mechanism 36 to reset. When resetting, the rotating motor 33 drives the heating mechanism 36 to rotate upward, and the first stamping column 17 and the second stamping column 18 punch the metal blank.

[0062] The diameter of the heating disk 363 is larger than the diameter of the first stamping column 17 . The larger diameter of the heating disk 363 can transfer heat more evenly, thereby preventing the first stamping column 17 from heating the stamping end surface of the second stamping column 18 unevenly.

[0063] By setting the output end of the rotating motor 33 to rotate forward, the rotating shaft 34 is driven to rotate, and the heating mechanism 36 is simultaneously driven to move to the stamping end surface position of the first stamping column 17 relative to the second stamping column 18, so as to heat the stamping end surfaces of the first stamping column 17 relative to the second stamping column 18. After heating, the rotating motor 33 can be reversed to drive the heating mechanism 36 to reset, thereby achieving the effect of heating the stamping end surfaces of the first stamping column 17 relative to the second stamping column 18 before stamping to avoid thermal expansion.

[0064] In the third embodiment, after the punch head is heated, the temperature reaches a suitable processing temperature, and the impurities in the metal blank can be processed out better, which will result in excessive oxide scale and impurities in the processing process.

[0065] See also Figure 7 The bottom of the stamping unit 1 is symmetrically provided with an adjusting mechanism 4, and a temperature control unit 5 is installed on both adjusting mechanisms 4. The adjusting mechanism 4 can collect the oxide scale and can drive the temperature control unit 5 to move to heat the column body of the first stamping column 17 and the second stamping column 18.

[0066] See also Figure 7 The two adjustment mechanisms 4 are respectively installed at the lower position of the first stamping column 17 relative to the second stamping column 18. The two adjustment mechanisms 4 include an adjusting motor 41. The output end of the adjusting motor 41 is installed with an adjusting slide rail 42. The adjusting slide rail 42 is installed on both sides of the lower module 15. The adjusting motor 41 is installed on the side wall of the stamping base 11. A screw rod is arranged inside the adjusting slide rail 42. One end of the screw rod is connected to the output end of the adjusting motor 41. An adjusting slider 43 is slidably installed above the adjusting slide rail 42, and the adjusting slider 43 is threadedly connected to the screw rod. A support block 44 is arranged on the adjusting slider 43. The adjusting motor 41 drives the adjusting slider 43 to move on the adjusting slide rail 42, and the movement of the adjusting slider 43 drives the support block 44 to move.

[0067] See also Figure 7 The support block 44 is in a U-shape, and the shape of the support block 44 is matched with the temperature control unit 5. A collecting slider 45 is slidably installed in the middle position of the support block 44, and a collecting groove 46 is installed on the collecting slider 45. The collecting groove 46 is in the shape of a semi-cylindrical groove. The collecting slider 45 can drive the collecting groove 46 to move on the support block 44. Since the temperature control unit 5 is installed above the support block 44, when the oxide scale in the collecting groove 46 is full, it is not convenient to clean it directly. By adjusting the position of the collecting slider 45, the collecting groove 46 is moved to a position that is convenient for cleaning. The shape design of the collecting groove 46 can prevent the oxide scale cleaned by the temperature control unit 5 from splashing outward, and the oxide scale will not be stuck in a dead corner and cannot be cleaned during cleaning.

[0068] By arranging the collecting slide block 45 to slide on the supporting block 44 and designing the shape of the collecting groove 46, the oxide scale discharged from the temperature control unit 5 can be better cleaned and the dead corners can be cleaned more easily.

[0069] See also Figure 8 and Fig. 9 The temperature control unit 5 includes a temperature control channel 58, which is installed above the adjustment mechanism 4. A driving bracket 51 is installed at the top middle position of the temperature control channel 58. The driving bracket 51 is divided into an upper and lower layer. A cleaning motor 52 is installed at the upper layer of the driving bracket 51. A third bevel gear 56 is installed at the output end of the cleaning motor 52. The first bevel gear 54 and the second bevel gear 55 are meshed on both sides of the third bevel gear 56. A driving shaft 53 is rotatably installed in the middle of the first bevel gear 54 and the second bevel gear 55. Both ends of the driving shaft 53 are installed on the side walls of the driving bracket 51. When the cleaning motor 52 rotates, the third bevel gear 56 is driven to rotate. When the third bevel gear 56 rotates, the first bevel gear 54 and the second bevel gear 55 are synchronously driven to rotate. The first bevel gear 54 rotates clockwise, and the second bevel gear 55 rotates counterclockwise.

[0070] See also Fig.10 , Fig.11 and Fig.12 A temperature control mechanism 57 is installed inside the temperature control channel 58.

The first limiting ring 572 and the second limiting ring 573 are respectively arranged on both sides of the middle electric heating ring 571. The first limiting ring 572 and the second limiting ring 573 can separate the three heating intervals. The first transmission mechanism 574 and the second transmission mechanism 575 are respectively arranged in the middle position of the first limiting ring 572 and the second limiting ring 573. Two through grooves are symmetrically provided on the outer wall of the temperature control channel 58. The outer walls of the first bevel gear 54 and the second bevel gear 55 are respectively penetrated into the two through grooves, and the first bevel gear 54 and the second bevel gear 55 are in the corresponding through grooves.

[0071] See also Fig.10 , Fig.11and Fig.12 The first transmission mechanism 574 also includes a first cleaning frame 5743, on which a first card slot 5744 is provided, which is clamped on the first limiting ring 572, and a first mounting groove 5745 is also provided on the first cleaning frame 5743.
