Description

Technical Field

[0001] The present invention relates to the technical field of valve processing equipment, and particularly relates to an auxiliary processing device for forging valve blanks. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow rate of fluids in a fluid system. It is a device that enables the medium (liquid, gas, powder) in pipelines and equipment to flow or stop and can control its flow rate. A valve is a control component in a pipeline fluid transportation system, used to change the cross-section of the passage and the flow direction of the medium, and has functions such as guiding, shutting off, throttling, check, diverting, or overflow pressure relief. Valves used for fluid control range from the simplest stop valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. The nominal diameter of valves ranges from extremely small instrument valves to industrial pipeline valves with a diameter of up to 10 m. It can be used to control the flow of various types of fluids such as water, steam, oil products, gases, mud, various corrosive media, liquid metals, and radioactive fluids. The working pressure of the valve can range from 0.0013 MPa to ultra-high pressure of 1000 MPa, and the working temperature can range from ultra-low temperature of -270 °C to high temperature of 1430 °C.

[0003] In the production process of valves, generally, raw materials need to be processed into blanks through a series of processes such as cutting, calcining, and forging, and then the blanks are successively subjected to rough machining and finish machining to obtain reliable-quality valve components. During the forging process of valve blanks, in existing forging equipment, such as a noise-reducing forging hammer for forging processing and facilitating blanking disclosed in Chinese Patent Publication No. CN111283128A, which includes a frame body, a guide rail, and a soundproof box. A hydraulic cylinder is provided at the top of the frame body, the hydraulic cylinder is detachably connected to the frame body, a hammer rod is provided at the bottom of the hydraulic cylinder, the hammer rod is fixedly connected to the hydraulic cylinder, and a forging hammer is provided at the bottom of the hammer rod; the anvil is slid through the guide rail, which facilitates the user to carry and place the anvil and the workpiece placed thereon. By operating the hydraulic pump, the extended hydraulic rod can directly push the anvil and the workpiece to move, reducing the labor intensity of the user pulling the anvil, saving time and effort, and improving the work efficiency of workpiece blanking. However, during the processing of the blank by this forging hammer, it is necessary to manually adjust the position of the blank, which poses a safety hazard. And when it is necessary to measure the size of the blank, it is also necessary to first remove the blank from the forging hammer equipment and then perform manual measurement, which is time-consuming and laborious, and seriously reduces the production efficiency and production quality of valve blanks.

[0004] Therefore, the present invention provides an auxiliary processing device for forging valve blanks, which has a simple structure, is convenient to use, and can automatically adjust the position of the valve blank. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an auxiliary processing device for forging valve blanks. By controlling the coordinated cooperation among the first rotation driving device, the second rotation driving device, the longitudinal driving device, and the transverse driving device, the blank during the forging process can be accurately adjusted automatically, saving manpower and material resources and improving the uniformity of the blank forging. At the same time, in cooperation with the pressure sensor on the clamping member, the size of the blank during the forging process can also be stably and automatically measured accurately, which is of great significance for promoting the high-quality and high-efficiency forging production of valve blanks.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] An auxiliary processing device for forging valve blanks includes a workbench and an annular rotating disk. The annular rotating disk is sleeved on the workbench and is rotationally connected to the workbench. A first rotation driving device is provided on the side wall of the workbench. The first rotation driving device is used to control the annular rotating disk to rotate around the workbench. A plurality of adjusting components are evenly arranged on the annular rotating disk. The adjusting component includes a mounting plate, a second rotation driving device, a longitudinal driving device, a transverse driving device, and a clamping member. The mounting plate is arranged on the top of the annular rotating disk. The longitudinal driving device is arranged at the bottom of the annular rotating disk. The driving shaft of the longitudinal driving device passes through the annular rotating disk and is connected to the mounting plate. The second rotation driving device is arranged on the mounting plate. The driving shaft of the second rotation driving device is connected to the transverse driving device. The driving shaft of the transverse driving device is connected to the clamping member.

[0008] Further, a circular guardrail is provided on the top of the circular rotating disk, and a notch corresponding to the adjusting component is provided on the circular guardrail. During the actual working process, for the blank to be forged, it is placed on the workbench, and then the lateral driving devices are started to work simultaneously. The clamping members are pushed from the outside to the inside, and the blank on the workbench is pushed to the central area of the workbench, so that the blank is directly below the forging hammer. At the same time, under the collaborative pushing of multiple clamping members, the blank is firmly clamped in the central area of the workbench to ensure that the blank will not shift during the forging process. When it is necessary to flip the blank, the clamping members on the left and right sides can be controlled to keep clamping the blank, and the lateral driving devices in the front and back are controlled to work, and the clamping members located on the front and back sides of the blank are retracted. Subsequently, the longitudinal driving devices on the left and right sides are started to work synchronously, and the mounting plate is lifted upward. During the upward movement of the mounting plate, the clamping members linked to the mounting plate are lifted synchronously, so as to lift the blank from the workbench and suspend it above the workbench. Then, the second rotary driving devices on the left and right sides are controlled to work, and the lateral driving devices are driven to rotate by the second rotary driving devices. During the rotation of the lateral driving devices, the clamping members arranged on the driving shafts of the lateral driving devices will rotate synchronously with the lateral driving devices, thereby realizing the flipping of the blank in the front and back directions. The flipping of the blank in the left and right directions can be realized in the same way. In addition, to improve the forging uniformity of the blank during forging, during the gap between the forging hammer's hammering of the blank, the first rotary driving device can be controlled to work, and the circular rotating disk is controlled to rotate around the workbench. Since the clamping members are connected to the circular rotating disk through the lateral driving devices, the second rotary driving devices, the mounting plate, and the longitudinal driving devices, when the circular rotating disk rotates, the clamping members will also rotate synchronously with the circular rotating disk, thereby realizing the rotational adjustment of the position of the blank during the forging process of the blank and improving the forging uniformity of the blank.

[0009] Further, a circular transmission member is provided at the bottom of the circular rotating disk, and a rotary transmission member is provided on the driving shaft of the first rotary driving device. The rotary transmission member is in transmission connection with the circular transmission member.

[0010] Further, the circular transmission member and the rotary transmission member are respectively gears, and the rotary transmission member is meshed with the circular transmission member through a speed reducer.

[0011] Further, the adjusting component is arranged around the workbench and is arranged on the same circumference.

[0012] Further, the longitudinal driving device and the lateral driving device are respectively cylinders.

[0013] Further, the longitudinal driving device and the lateral driving device are respectively cylinders with stroke control functions.

[0014] Furthermore, a pressure sensor is provided on the clamping member, and the pressure sensor is linked with the lateral driving device. During the actual working process, for the billet in forging, its dimensions need to be measured to ensure that the forging quality of the billet meets the expected requirements. When it is necessary to measure the dimensions of the billet during forging, since the position of the lateral driving device is fixed in the initial state, the distance between two opposite lateral driving devices and the distance between the clamping members on the lateral driving devices are both fixed values. When the billet is not clamped by the clamping members, the length dimension of the billet in the left-right direction can be measured. Then, the lateral driving devices on both sides can be controlled to work, pushing the clamping members to approach the billet in the middle from both sides. When the clamping members come into contact with the billet, the pressure sensor detects the corresponding signal, and the lateral driving device corresponding to the pressure sensor immediately stops working. After both the left and right clamping members come into contact with the billet, both lateral driving devices stop working. At this time, since the lateral driving device has a stroke control function, the moving stroke of the two clamping members can be counted. Subtracting the moving stroke of the two clamping members from the distance between the two clamping members at the initial position, the length dimension of the billet in the left-right direction can be obtained, realizing the measurement of the length dimension of the billet. When the billet is in the clamped state, the front and rear clamping members can be controlled to maintain the clamping state first, then the lateral driving devices on both sides can be controlled to retract the clamping members to the initial position, and then the clamping members on both sides can be controlled to approach the billet and come into contact with the billet, thereby realizing the stable and accurate measurement of the length dimension of the billet in the left-right direction. Similarly, the width dimension of the billet in the front-rear direction can also be measured. For the height of the billet, after controlling the billet to be flipped so that the height becomes the length or width, the measurement can be carried out again.

[0015] Furthermore, the clamping member includes a connecting base, an elastic member, and a clamping portion. The connecting base is connected to the clamping portion through the elastic member. The driving shaft of the lateral driving device is connected to the connecting base. The pressure sensor is arranged on the side wall of the clamping portion away from the connecting base. By setting the clamping member to include a connecting base, an elastic member, and a clamping portion, and connecting the connecting base to the clamping portion through the elastic member, when the clamping member firmly clamps the billet on the workbench and the forging hammer hammers the billet for forging, the elastic member is used to absorb the energy during the hammering process of the billet, thereby effectively reducing the loss of the clamping member and the lateral driving device and improving the service life of the equipment. In a preferred forging process, the pressure sensor is used to detect the extrusion pressure between the billet and the clamping member. After the extrusion pressure reaches a predetermined value, the corresponding lateral driving device can be controlled to first retract the clamping member, and then push the clamping member to clamp the billet again, so as to reduce the extrusion wear between the billet and the clamping member and improve the service life of the equipment.

[0016] Furthermore, the elastic member is a wavy spring piece.

[0017] Further, an anti-slip layer is provided on the side wall of the clamping portion away from the connecting base.

[0018] Further, four adjusting components are evenly arranged on the annular rotating disc. By evenly arranging four adjusting components on the annular rotating disc, two opposite adjusting components are located on the same diameter of the annular rotating disc, so that the clamping member clamps the embryo workpiece during operation, improving the clamping stability of the clamping member to the embryo workpiece, and facilitating the coordinated control of the longitudinal driving device, the second rotation driving device, the transverse driving device and the first rotation driving device to adjust the position and measure the size of the embryo workpiece, effectively improving the use convenience of the equipment and the forging efficiency of the embryo workpiece.

[0019] Further, auxiliary control components are respectively arranged at the tails of the first rotation driving device and the second rotation driving device. The auxiliary control component includes an annular fixed substrate, an annular elastic member, a magnetic ring, an annular clamping member and a linkage member. The linkage member includes a left limiting portion, a movable portion, a clamping portion and a right limiting portion arranged in sequence from left to right. The annular clamping member is sleeved on the movable portion, and the annular clamping member can freely rotate around the movable portion. The maximum diameter of the clamping portion is smaller than the inner diameter of the annular clamping member. A plurality of card slots are evenly arranged on the side wall of the clamping portion. A plurality of card strips are evenly arranged on the inner wall of the annular clamping member. The card slots are matched with the card strips. The left limiting portion and the right limiting portion are used to limit the annular clamping member between the left limiting portion and the right limiting portion. The annular fixed substrate is connected to the housing of the rotation driving device. The magnetic ring is connected to the annular fixed substrate through the annular elastic member. An electromagnetic member is embedded on the side wall of the annular fixed substrate close to the magnetic ring. The electromagnetic member is arranged corresponding to the magnetic ring. The annular clamping member is connected to the magnetic ring through a plurality of first connecting rods. The first connecting rods are evenly arranged around the left limiting portion. The left end of the left limiting portion is connected to the motor shaft of the rotation driving device.

[0020] Furthermore, the auxiliary control component further includes at least one slide bar. The left end of the slide bar passes through the magnetic ring and is fixedly connected to the annular fixed substrate, and the slide bar is slidably connected to the magnetic ring. A limiting block is provided at the right end of the slide bar. During the actual working process, when it is necessary to rotate the clamping member or the annular rotating disk, the corresponding rotation driving device is started to work. At this time, when the electromagnetic member is in the power-off state, and at the same time the annular clamping member is located at the movable part, the linkage member connected to the motor shaft of the rotation driving device rotates synchronously with the motor shaft. And because the annular clamping member is at the movable part of the linkage member, the annular clamping member can rotate freely around the movable part, because the annular clamping member has no connection with the linkage member at this time; after the clamping member or the annular rotating disk is rotated to the predetermined position, at this time, the rotation driving device is stopped from working, and the electromagnetic member is controlled to be powered on. In the state where the electromagnetic member is powered on, the electromagnetic member applies a repulsive thrust to the right on the magnetic ring, pushing the annular clamping member connected to the magnetic ring from the movable part into the clamping part, so that the clamping bar is in the card slot. Affected by the transmission between the clamping bar and the card slot, a transmission relationship is established between the annular clamping member and the clamping part of the linkage member. At the same time, because the magnetic ring can only slide along the slide bar and cannot rotate, while restricting the magnetic ring from rotating, the slide bar also restricts the rotation of the annular clamping member connected to the magnetic ring. Therefore, after the annular clamping member is pushed from the movable part into the clamping part, the annular clamping member restricts the linkage member from rotating, and at the same time restricts the motor shaft of the rotation driving device from rotating, thereby locking the position of the clamping member or the annular rotating disk, ensuring accurate and stable adjustment of the position of the blank, realizing accurate hammering of the blank at the predetermined position by the forging hammer, effectively improving the forging accuracy of the blank, and enhancing the forging quality of the blank.

[0021] Furthermore, in the state where the electromagnetic member is powered on, the electromagnetic member applies a repulsive thrust to the right on the magnetic ring, pushing the annular clamping member connected to the magnetic ring from the movable part into the clamping part; in the state where the electromagnetic member is powered off, the annular elastic member applies a pulling force to the left on the magnetic ring, pulling the annular clamping member connected to the magnetic ring back from the clamping part to the movable part.

[0022] Furthermore, the electromagnetic member is interlocked with the corresponding rotation driving device. When the electromagnetic member is powered on and working, the corresponding rotation driving device is in the power-off state, and when the rotation driving device is powered on and working, the corresponding electromagnetic member is in the power-off state.

[0023] Further, the auxiliary control component further includes a signal board, which is arranged on the right side of the right limiting part. The signal board is connected to the housing of the rotary driving device through multiple second connecting rods. A magnetic surface layer is arranged on the right side wall of the right limiting part, and a plurality of signal concave points are evenly arranged on the magnetic surface. The signal concave points are located on the same circumference. At least one Hall sensor is evenly arranged on the side wall of the signal board close to the right limiting part. During the actual working process, since the output ratio of the rotary driving device is a fixed value, the Hall sensor on the signal board cooperates with the signal concave points to divide the process of the motor shaft of the rotary driving device rotating one circle into multiple point signals for recording. Then, by counting the number of point signals detected by the Hall sensor, the number of rotations of the motor shaft can be accurately calculated, and then converted through the output ratio of the rotary driving device, so that the rotation angle of the annular rotary disk or the transverse driving device can be accurately calculated. Combining with the locking function of the auxiliary control component for the motor shaft, the accurate control and locking of the rotation angle of the annular rotary disk or the transverse driving device can be realized, thereby assisting in improving the forging accuracy and forging efficiency of the blank.

[0024] Further, the Hall sensors are located on the same circumference.

[0025] Further, the Hall sensors are arranged corresponding to the signal concave points.

[0026] Further, three signal concave points are evenly arranged on the magnetic surface, and four Hall sensors are evenly arranged on the side wall of the signal board close to the right limiting part. By evenly arranging three signal concave points on the magnetic surface and four Hall sensors on the side wall of the signal board close to the right limiting part, and through the cooperation between the Hall sensors and the signal concave points, the detection of 12 points can be realized, that is, it can accurately detect that a detection signal corresponds to every 30° rotation of the motor shaft of the rotary driving device. Then, through conversion by the output ratio of the rotary driving device, the rotation angle of the annular rotary disk or the transverse driving device can be accurately calculated, and further the rotation angle of the blank can be accurately controlled to ensure the accurate and safe progress of the blank forging process.

[0027] The beneficial effects of the present invention are as follows: The auxiliary processing device for forging valve blanks of the present invention can effectively and automatically adjust the blank accurately during the forging process through the coordinated cooperation among the first rotary driving device, the second rotary driving device, the longitudinal driving device and the transverse driving device, saving manpower and material resources and improving the uniformity of blank forging; at the same time, in cooperation with the pressure sensor on the clamping part, it can also stably and automatically and accurately measure the size of the blank during the forging process, which is of great significance for promoting the high-quality and high-efficiency forging production of valve blanks.

Detailed implementation manners

[0036] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0037] As Figures 1 to 7As shown in the figure, an auxiliary processing device for forging valve blanks includes a workbench 1 and an annular rotating disk 2. The annular rotating disk 2 is sleeved on the workbench 1 and is rotationally connected to the workbench 1. A first rotation driving device 3 is arranged on the side wall of the workbench 1, and the first rotation driving device 3 is used to control the annular rotating disk 2 to rotate around the workbench 1. A plurality of adjusting components 4 are evenly arranged on the annular rotating disk 2. The adjusting component 4 includes a mounting plate 401, a second rotation driving device 402, a longitudinal driving device 403, a transverse driving device 404 and a clamping member 405. The mounting plate 401 is arranged on the top of the annular rotating disk 2, the longitudinal driving device 403 is arranged at the bottom of the annular rotating disk 2, and the driving shaft of the longitudinal driving device 403 passes through the annular rotating disk 2 and is connected to the mounting plate 401. The second rotation driving device 402 is arranged on the mounting plate 401, the driving shaft of the second rotation driving device 402 is connected to the transverse driving device 404, and the driving shaft of the transverse driving device 404 is connected to the clamping member 405.

[0038] Specifically, a ring-shaped guardrail 5 is provided on the top of the ring-shaped rotating disk 2, and a notch corresponding to the adjusting assembly 4 is provided on the ring-shaped guardrail 5. During the actual working process, for the blank to be forged, it is placed on the workbench 1, and then the lateral driving device 404 is started to work simultaneously. The clamping member 405 is pushed from the outside to the inside, and the blank on the workbench 1 is pushed to the central area of the workbench 1, so that the blank is directly below the forging hammer. At the same time, under the coordinated pushing of multiple clamping members 405, the blank is firmly clamped in the central area of the workbench 1 to ensure that the blank does not shift during the forging process. When the blank needs to be flipped, the clamping members 405 on the left and right sides can be controlled to keep clamping the blank, and the lateral driving devices 404 in the front and back are controlled to work, so that the clamping members 405 on both sides of the blank retreat. Subsequently, the longitudinal driving devices 403 on the left and right sides are started to work synchronously to lift the mounting plate 401 upward. During the upward movement of the mounting plate 401, the clamping member 405 linked to the mounting plate 401 rises synchronously, realizing the lifting of the blank from the workbench 1 and suspending it above the workbench 1. Then, the second rotation driving devices 402 on the left and right sides are controlled to work, and the lateral driving device 404 is driven to rotate by the second rotation driving device 402. During the rotation of the lateral driving device 404, the clamping member 405 arranged on the driving shaft of the lateral driving device 404 rotates synchronously with the lateral driving device 404, thereby realizing the flipping of the blank in the front-back direction. The flipping of the blank in the left-right direction can be realized in the same way. In addition, to improve the forging uniformity of the blank during forging, during the gap between the forging hammer's hammering of the blank, the first rotation driving device 3 can be controlled to make the ring-shaped rotating disk 2 rotate around the workbench 1. When the clamping member 405 clamps the blank, since the clamping member 405 is connected to the ring-shaped rotating disk 2 through the lateral driving device 404, the second rotation driving device 402, the mounting plate 401, and the longitudinal driving device 403, when the ring-shaped rotating disk 2 rotates, the clamping member 405 will also rotate synchronously with the ring-shaped rotating disk 2, thereby realizing the rotational adjustment of the blank's position during the forging process of the blank and improving the forging uniformity of the blank.

[0039] Specifically, a ring-shaped transmission member 6 is provided at the bottom of the ring-shaped rotating disk 2, and a rotating transmission member is provided on the driving shaft of the first rotation driving device 3. The rotating transmission member is in transmission connection with the ring-shaped transmission member 6.

[0041] Specifically, the adjusting assembly 4 is arranged around the workbench 1 and is arranged on the same circumference.

[0042] Specifically, the longitudinal driving device 403 and the lateral driving device 404 are respectively cylinders.

[0043] Specifically, the longitudinal driving device 403 and the transverse driving device 404 are respectively cylinders with stroke control functions.

[0044] Specifically, a pressure sensor 4054 is provided on the clamping member 405, and the pressure sensor 4054 is linked with the transverse driving device 404. During the actual working process, for the blank in forging, its dimensions need to be measured to ensure that the forging quality of the blank meets the expected requirements. During the process of measuring the dimensions of the forging blank, since the position of the transverse driving device 404 is fixed in the initial state, the distance between two opposite transverse driving devices 404 and the distance between the clamping members 405 on the transverse driving device 404 are both fixed values. When the blank is not clamped by the clamping member 405, by measuring the length dimension of the blank in the left-right direction, the transverse driving devices 404 on both sides can be controlled to work, pushing the clamping members 405 to approach the blank in the middle from both sides. When the clamping member 405 touches the blank, the pressure sensor 4054 detects a corresponding signal, and the transverse driving device 404 linked with the pressure sensor 4054 immediately stops working. After both the left and right clamping members 405 touch the blank, both transverse driving devices 404 stop working. At this time, since the transverse driving device 404 has a stroke control function, the moving stroke of the two clamping members 405 can be counted. Subtracting the moving stroke of the two clamping members 405 from the distance between the two clamping members 405 at the initial position, the length dimension of the blank in the left-right direction can be obtained, realizing the measurement of the length dimension of the blank; when the blank is in the clamped state, the front and rear clamping members 405 can be controlled to maintain the clamping state first, then the transverse driving devices 404 on both sides can be controlled to retract the clamping members 405 to the initial position, and then the clamping members 405 on both sides can be controlled to approach the blank and touch the blank, thereby realizing the stable and accurate measurement of the length dimension of the blank in the left-right direction; similarly, the width dimension of the blank in the front-rear direction can also be measured; for the height of the blank, after controlling the blank to be flipped to change the height to the length or width, the measurement can be carried out.

After the extrusion pressure reaches a predetermined value, the corresponding lateral drive device 404 can be controlled to first retract the clamping member 405, and then push the clamping member 405 to clamp the blank again, so as to reduce the extrusion wear between the blank and the clamping member 405 and improve the service life of the equipment.

By evenly disposing four adjusting components 4 on the annular rotating disk 2, such that two opposite adjusting components 4 are located on the same diameter of the annular rotating disk 2, thereby enabling the clamping member 405 to achieve alignment clamping of the blank during the working process, improving the clamping stability of the clamping member 405 to the blank, and facilitating the control of the longitudinal drive device 403, the second rotation drive device 402, the lateral drive device 404, and the first rotation drive device 3 to cooperate with each other to adjust the position and measure the size of the blank, effectively improving the use convenience of the equipment and the forging efficiency of the blank.

[0049] Specifically, auxiliary control components 8 are respectively arranged at the tails of the first rotation driving device 3 and the second rotation driving device 402. The auxiliary control component 8 includes an annular fixed substrate 801, an annular elastic member 802, a magnetic ring 803, an annular clamping member 804 and a linkage member. The linkage member includes a left limiting portion 806, a movable portion 807, a clamping portion 808 and a right limiting portion 809 which are arranged in sequence from left to right. The annular clamping member 804 is sleeved on the movable portion 807, and the annular clamping member 804 can freely rotate around the movable portion 807. The maximum diameter of the clamping portion 808 is smaller than the inner diameter of the annular clamping member 804. A plurality of clamping grooves 810 are uniformly arranged on the side wall of the clamping portion 808, and a plurality of clamping strips 811 are uniformly arranged on the inner wall of the annular clamping member 804. The clamping grooves 810 are matched with the clamping strips 811. The left limiting portion 806 and the right limiting portion 809 are used for limiting the annular clamping member 804 between the left limiting portion 806 and the right limiting portion 809. The annular fixed substrate 801 is connected to the housing of the rotation driving device.

The first connecting rods 812 are uniformly arranged around the left limiting portion 806. The left end of the left limiting portion 806 is connected to the motor shaft 819 of the rotation driving device.

[0050] Specifically, the auxiliary control component 8 further includes at least one slide bar 813. The left end of the slide bar 813 passes through the magnetic ring 803 and is fixedly connected to the annular fixed substrate 801, and the slide bar 813 is slidably connected to the magnetic ring 803. A limit block 814 is provided at the right end of the slide bar 813. During the actual working process, when it is necessary to rotate the clamping member 405 or the annular rotating disk 2, the corresponding rotation driving device is started to work. At this time, in the power-off state of the electromagnetic member 805, and at the same time, the annular clamping member 804 is located at the movable part 807. The linkage member connected to the motor shaft 819 of the rotation driving device rotates synchronously with the motor shaft 819. And because the annular clamping member 804 is at the movable part 807 of the linkage member, the annular clamping member 804 can rotate freely around the movable part 807 because the annular clamping member 804 has no connection with the linkage member at this time; after the clamping member 405 or the annular rotating disk 2 is rotated to a predetermined position, at this time, the rotation driving device is stopped from working, and the electromagnetic member 805 is controlled to be energized. In the energized state of the electromagnetic member 805, the electromagnetic member 805 exerts a repulsive thrust to the right on the magnetic ring 803, and pushes the annular clamping member 804 connected to the magnetic ring 803 from the movable part 807 into the clamping part 808, so that the clamping strip 811 is in the clamping groove 810. Affected by the transmission between the clamping strip 811 and the clamping groove 810, a transmission relationship is established between the annular clamping member 804 and the clamping part 808 of the linkage member. At the same time, because the magnetic ring 803 can only slide along the slide bar 813 and cannot rotate, while restricting the magnetic ring 803 from rotating, the slide bar 813 also restricts the rotation of the annular clamping member 804 connected to the magnetic ring 803. Therefore, after the annular clamping member 804 is pushed from the movable part 807 into the clamping part 808, the annular clamping member 804 restricts the linkage member from rotating, and at the same time, it also restricts the motor shaft 819 of the rotation driving device from rotating, thereby locking the position of the clamping member 405 or the annular rotating disk 2, ensuring accurate and stable adjustment of the position of the blank, realizing accurate hammering of the blank at the predetermined position by the forging hammer, effectively improving the forging accuracy of the blank, and improving the forging quality of the blank.

[0051] Specifically, in the energized state of the electromagnetic member 805, the electromagnetic member 805 exerts a repulsive thrust to the right on the magnetic ring 803, and pushes the annular clamping member 804 connected to the magnetic ring 803 from the movable part 807 into the clamping part 808; in the power-off state of the electromagnetic member 805, the annular elastic member 802 exerts a pulling force to the left on the magnetic ring 803, and pulls the annular clamping member 804 connected to the magnetic ring 803 from the clamping part 808 back to the movable part 807.

[0052] Specifically, the electromagnetic member 805 is interlocked with the corresponding rotation driving device. When the electromagnetic member 805 is energized and working, the corresponding rotation driving device is in the power-off state, and when the rotation driving device is energized and working, the corresponding electromagnetic member 805 is in the power-off state.

[0053] Specifically, the auxiliary control component further includes a signal board 815. The signal board 815 is disposed on the right side of the right limit portion 809. The signal board 815 is connected to the housing of the rotary drive device through a plurality of second connecting rods 818. A magnetic surface layer is provided on the right side wall of the right limit portion 809. A plurality of signal indentations 816 are uniformly arranged on the magnetic surface. The signal indentations 816 are located on the same circumference. At least one Hall sensor 817 is uniformly arranged on the side wall of the signal board 815 close to the right limit portion 809. During the actual working process, since the output ratio of the rotary drive device is a fixed value, the Hall sensor 817 on the signal board 815 cooperates with the signal indentations 816 to divide the process of the motor shaft 819 of the rotary drive device rotating one circle into a plurality of point signals for recording. Then, by counting the number of point signals detected by the Hall sensor 817, the number of rotations of the motor shaft 819 is accurately calculated, and then converted through the output ratio of the rotary drive device. Thus, the rotation angle of the annular rotary disk 2 or the transverse drive device can be accurately calculated. With the locking function of the auxiliary control component 8 for the motor shaft 819, the accurate control and locking of the rotation angle of the annular rotary disk 2 or the transverse drive device 404 can be achieved, thereby assisting in improving the forging accuracy and forging efficiency of the blank.

[0054] Specifically, the Hall sensors 817 are located on the same circumference.

[0055] Specifically, the Hall sensors 817 are arranged corresponding to the signal indentations 816.

[0056] Specifically, three signal indentations 816 are uniformly arranged on the magnetic surface, and four Hall sensors 817 are uniformly arranged on the side wall of the signal board 815 close to the right limit portion 809. By uniformly arranging three signal indentations 816 on the magnetic surface and four Hall sensors 817 on the side wall of the signal board 815 close to the right limit portion 809, and through the cooperation between the Hall sensors 817 and the signal indentations 816, the detection of 12 points can be realized, that is, it can be accurately detected that each time the motor shaft 819 of the rotary drive device rotates 30°, a detection signal corresponds. Then, through conversion by the output ratio of the rotary drive device, the rotation angle of the annular rotary disk 2 or the transverse drive device 404 can be accurately calculated, and further the rotation angle of the blank can be accurately controlled, ensuring the accurate and safe progress of the blank forging process.

[0057] Preferably, the auxiliary processing device further includes a control module and a power supply. The first rotary drive device 3, the second rotary drive device 402, the longitudinal drive device 403, the transverse drive device 404, the pressure sensor 4054, the electromagnetic member 805, the Hall sensors 817, and the power supply are respectively connected to the control module.

[0058] When in use, when forging the valve blank, place the valve blank on the workbench 1, and then start the lateral drive device 404 to work simultaneously. Push the clamping member 405 from the outside to the inside, and push the blank on the workbench 1 to the central area of the workbench 1, so that the blank is directly below the forging hammer. At the same time, under the coordinated push of multiple clamping members 405, firmly clamp the blank in the central area of the workbench 1 to ensure that the blank will not shift during the forging process. When it is necessary to flip the blank, the clamping members 405 on the left and right sides can be controlled to keep clamping the blank, and the lateral drive devices 404 in the front and back can be controlled to work, so that the clamping members 405 on both sides of the blank retract. Subsequently, start the longitudinal drive devices 403 on the left and right sides to work synchronously, and lift the mounting plate 401 upward. During the upward movement of the mounting plate 401, the clamping member 405 linked to the mounting plate 401 rises synchronously, realizing lifting the blank from the workbench 1 and suspending it above the workbench 1. Then, control the second rotation drive device 402 on the left and right sides to work, and drive the lateral drive device 404 to rotate by using the second rotation drive device 402. Since the output reduction ratio of the rotation drive device is a fixed value, and the Hall sensor 817 on the signal plate 815 cooperates with the signal concave point 816, the process of the motor shaft 819 of the rotation drive device rotating one circle is divided into multiple point signals for recording. Then, by counting the number of point signals detected by the Hall sensor 817, the number of rotation circles of the motor shaft 819 can be accurately calculated, and then converted through the output reduction ratio of the rotation drive device, so that the rotation angle of the annular rotating disk 2 or the lateral drive device can be accurately calculated. During the rotation of the lateral drive device 404, the clamping member 405 arranged on the drive shaft of the lateral drive device 404 rotates synchronously with the lateral drive device 404, thereby realizing the flipping of the blank in the front and back directions. The flipping of the blank in the left and right directions can be realized in the same way. In addition, to improve the forging uniformity of the blank during forging, during the gap between the forging hammer hitting the blank, the first rotation drive device 3 can be controlled to work, and the annular rotating disk 2 can be controlled to rotate around the workbench 1. When the clamping member 405 clamps the blank, since the clamping member 405 is connected to the annular rotating disk 2 through the lateral drive device 404, the second rotation drive device 402, the mounting plate 401 and the longitudinal drive device 403, when the annular rotating disk 2 rotates, the clamping member 405 will also rotate synchronously with the annular rotating disk 2, thereby realizing the rotational adjustment of the position of the blank during the forging process of the blank and improving the forging uniformity of the blank. At the same time, in cooperation with the pressure sensor 4054 on the clamping member 405, it is also possible to stably and automatically and accurately measure the size of the blank during the forging process, which is of great significance for promoting the high-quality and high-efficiency forging production of valve blanks.
