Description

Technical Field

[0001] The invention relates to the technical field of auxiliary facilities for steel ball production, and in particular to a steel ball shaping device with a displacement compensation function and a method thereof. Background Art

[0002] After the wear-resistant steel balls are formed by the forming machine, they need to be reshaped by a shaping machine while they are still in a high temperature state.

[0003] For example, Chinese patent CN108838615A discloses a steel ball shaping device, which drives a rotating shaping ring to rotate through a power transmission mechanism, so that the steel ball located between the rotating shaping ring and the fixed shaping ring moves from the introduction cavity to the outlet cavity; in this process, a spring buffer mechanism is used to provide displacement buffering for the fixed shaping ring to avoid the steel ball from being stuck, and at the same time, the spring buffer mechanism applies pressure to the steel ball through the fixed buffer ring to achieve the shaping of the steel ball.

[0004] However, the elastic force provided by the spring varies with the compression length. When the fixed shaping ring and the rotating shaping ring are against each other, the extrusion force provided by the spring is sufficient to deform the protruding part on the high-temperature steel ball. If the size deviation of the high-temperature steel ball to be shaped is large, the steel ball pushes the fixed shaping ring to move during the shaping process, and the fixed shaping ring squeezes the spring, causing the spring to produce a larger elastic force (the structural principle of the spring determines that it cannot provide a relatively linear constant pressure). The elastic force reacts on the fixed shaping ring, which easily causes the high-temperature steel ball to be clamped by the fixed shaping ring and the rotating shaping ring, thereby causing the high-temperature steel ball to be stuck between the rotating shaping ring and the fixed shaping ring. In addition, the spring is continuously and repeatedly compressed, which is prone to fatigue failure. Under this premise, a device that can provide a smooth and constant pressure and is continuously reliable is needed to ensure the continuous and stable operation of the equipment.

[0005] Based on this, the present invention designs a steel ball shaping device with displacement compensation function and a method thereof to solve the above problems. Summary of the invention

[0021] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a steel ball shaping device with a displacement compensation function, comprising the following steps:

[0022] Step 1: According to the shaping accuracy requirements, different numbers of gravity blocks are placed on the upper side of the support plate, and the gravity blocks are limited by the sliding rod; the gravity block presses down the second piston rod through the support plate, and the second piston rod moves vertically under the guidance of the guide rod, thereby driving the second piston to move vertically in the vertical cavity; the second piston presses down the hydraulic oil, so that the hydraulic oil pushes the first piston in the horizontal cavity to move horizontally, and the first piston drives the first piston rod to move horizontally, thereby driving the fixed disk shaft to move horizontally through the insulation block, and the fixed disk shaft pushes the fixed disk to move horizontally under the support and limiting action of the sliding support seat, thereby pushing the fixed shaping ring to move horizontally, until the fixed shaping ring fits with the rotating shaping ring and is blocked by the rotating shaping ring;

[0023] Step 2: Start the driving mechanism, which drives the rotating disk to rotate through the rotating disk shaft, thereby driving the rotating shaping ring to rotate;

[0024] Step 3: The steel ball in a high temperature state is introduced into the annular groove composed of the fixed shaping groove and the rotating shaping groove through the introduction cavity. The steel ball is blocked by the partition plate and rotates under the drive of the rotating shaping ring. Through the setting of the rotating shaping groove and the fixed shaping groove, the rotating shaping groove supports the steel ball asymmetrically up and down, which is convenient for the steel ball to rotate while revolving around the fixed shaping groove; in this process, the protruding part on the steel ball contacts the rotating shaping groove and the fixed shaping groove, the steel ball pushes the fixed shaping ring to move to the left, and the fixed shaping ring drives the fixed disk and the fixed disk axis to move to the left;

[0025] Step 4: The fixed disk shaft pushes the first piston rod and the first piston to move in the horizontal cavity through the heat insulation block, thereby applying pressure to the hydraulic oil in the horizontal cavity and pushing the second piston rod and the second piston to move upward in the vertical cavity, thereby pushing the support plate and the gravity block on the upper side of the support plate to move upward; if the size of the steel ball meets the standard, proceed to step five; if the size of the steel ball exceeds the standard, proceed to step six;

[0026] Step 5: The support plate drives the mounting plate, the conductive block and the conductive spring to move vertically; the conductive spring is always in contact with the insulating cylinder and the resistance wire coil through the ball at the end; the horizontal movement distance of the fixed shaping ring is always in a small range, and the vertical movement distance of the support plate is small at this time; the conductive spring is only in contact with the insulating cylinder during the entire shaping stage, and the conductive spring is not in contact with the resistance wire coil, so that the circuit including the conductive spring and the resistance wire coil is disconnected as a whole;

[0027] Step 6: The horizontal movement distance of the fixed shaping ring is relatively large, and the supporting plate is pushed to move vertically upward by a relatively large distance during the shaping process, thereby driving the conductive reed to move upward, so that the steel ball at the end of the conductive reed contacts the resistance wire coil, and the circuit including the conductive reed and the resistance wire coil is connected; the circuit current is monitored by a multimeter, and whether the size of the steel ball to be shaped meets the standard is judged according to whether the current signal exists, and the range of the steel ball size exceeding the standard is judged according to the size of the current signal;

[0028] Step 7: When executing step 4, step 5 or step 6, the gravity of the support plate and the gravity block on the upper side of the support plate reacts to the support plate through the hydraulic oil, forming a thrust on the first piston, the first piston rod, and the insulation block, so that the fixed disk shaft and the fixed disk always push the fixed shaping ring to approach the rotating shaping ring, always maintain pressure on the steel ball, and squeeze and shape the protruding part of the steel ball; until the rotating shaping ring drives the steel ball to move to the lead-out groove, the steel ball falls into the guide groove through the lead-out groove and the lead-out cavity to complete the shaping.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A steel ball in a high-temperature state is thrown between the rotary shaping component and the fixed shaping component, and the driving mechanism drives the rotary shaping component to rotate, thereby driving the steel ball to roll between the rotary shaping component and the fixed shaping component, and the steel ball is caused to rotate while orbiting along the fixed shaping component through the extrusion and friction between the rotary shaping component and the fixed shaping component, until the steel ball is shaped and moves out from between the rotary shaping component and the fixed shaping component and falls into the guide trough; in this process, the adjustable weight pressure component presses down the hydraulic oil in the buffer cylinder through its own gravity, and the pressure of the hydraulic oil in the buffer cylinder pushes the displacement compensation component; the gravity of the adjustable weight pressure component remains unchanged, and the pressure of the hydraulic oil in the buffer cylinder remains unchanged, so that the thrust of the hydraulic oil in the buffer cylinder on the displacement compensation component remains unchanged; the displacement compensation component provides displacement compensation for the fixed shaping component, and at the same time provides a constant pressure for the steel ball to shape the steel ball, so as to avoid the steel ball from getting stuck and make the shaping process smoother and more uniform;

[0030] 2. Before use, the gravity of the adjustable weight pressure assembly can be changed according to the requirements of the shaping strength to adapt it to the shaping requirements of different precisions; and the adjustable weight pressure assembly relies on its own gravity to apply pressure to the hydraulic oil in the buffer cylinder. The gravity of the section weight pressure assembly remains unchanged, and the pressure on the hydraulic oil in the buffer cylinder remains unchanged, so that the thrust of the hydraulic oil in the buffer cylinder on the displacement compensation assembly remains unchanged, thereby avoiding insufficient pressure due to spring fatigue and affecting the shaping quality;

[0031] 3. During the shaping process, the overall displacement of the fixed shaping component and the displacement compensation component changes slightly. The movement of the displacement compensation component drives the adjustable heavy pressure component to move synchronously through the buffer cylinder, and the displacement of the adjustable heavy pressure component is much larger than that of the displacement compensation component. Therefore, the displacement of the adjustable heavy pressure component can be detected by the monitoring mechanism to calculate the displacement of the displacement compensation component, thereby improving the monitoring accuracy. When the size of the steel ball to be shaped meets the standard and the displacement of the fixed shaping component and the displacement compensation component changes slightly, the monitoring mechanism will not start at this time. When the size of the steel ball to be shaped exceeds the standard, the monitoring mechanism will start automatically. The monitoring mechanism monitors the displacement of the adjustable heavy pressure component to determine whether there is a deviation in the size of the steel ball entering the rotary shaping component and the fixed shaping component, as well as the corresponding deviation difference range. This facilitates timely detection of faults and timely resolution, thereby preventing steel balls with large size deviations from damaging the shaping device. At the same time, it prevents the monitoring mechanism from always being in the monitoring state, causing fatigue and affecting the overall service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0046] Embodiment 1: In some embodiments, please refer to the drawings of the specification Figure 1-Figure 4 , a steel ball shaping device with displacement compensation function, comprising a frame 1;

[0047] A shaping mechanism 3 for shaping the steel ball is installed in the middle of the frame 1, and the shaping mechanism 3 includes a rotary shaping component 31, a fixed shaping component 32 and a guide trough 33. The frame 1 is provided with a rotary shaping component 31 for driving the steel ball to rotate and a fixed shaping component 32 for cooperating with the rotary shaping component 31 to shape the steel ball; the frame 1 is provided with a guide trough 33 for guiding the shaped steel ball; the guide trough 33 is located at the lower side of the rotary shaping component 31 and the fixed shaping component 32;

[0048] A driving mechanism 2 for delivering power to the rotary shaping assembly 31 is installed on the right side of the frame 1, and a hydraulic buffer mechanism 4 for performing displacement compensation and buffering on the fixed shaping assembly 32 is installed on the left side of the frame 1;

[0049] The hydraulic buffer mechanism 4 includes a buffer cylinder 41, a displacement compensation component 42 and an adjustable weight pressure component 43. The buffer cylinder 41 is installed on the left side of the frame 1. The horizontal outlet of the buffer cylinder 41 is installed with the displacement compensation component 42 for supporting the fixed shaping component 32, and the vertical outlet of the buffer cylinder 41 is installed with the adjustable weight pressure component 43 for adjusting the buffer strength; hydraulic oil is filled between the displacement compensation component 42 and the adjustable weight pressure component 43 inside the buffer cylinder 41;

[0050] The frame 1 and the adjustable weight pressing assembly 43 are provided with a monitoring mechanism 5 for monitoring the outer dimensions of the steel ball.

[0051] The buffer cylinder 41 causes the displacement compensation component 42 and the adjustable weight pressure component 43 to move synchronously, and the displacement of the adjustable weight pressure component 43 is greater than that of the displacement compensation component 42; the monitoring mechanism 5 directly monitors the displacement of the adjustable weight pressure component 43, and infers the displacement of the displacement compensation component 42 and the fixed shaping component 32 through the displacement of the adjustable weight pressure component 43, and infers the size of the steel ball through the displacement of the fixed shaping component 32.

[0052] The driving mechanism 2 includes a motor and a reducer, the output shaft of the motor is fixedly connected to the power input shaft of the reducer, and the power output shaft of the reducer is fixedly connected to the rotary shaping component 31 through a coupling.

[0053] In this embodiment, when the steel ball shaping device with displacement compensation function works normally, the steel ball in a high temperature state is thrown between the rotary shaping component 31 and the fixed shaping component 32, and the driving mechanism 2 drives the rotary shaping component 31 to rotate, thereby driving the steel ball to roll between the rotary shaping component 31 and the fixed shaping component 32, and through the extrusion and friction between the rotary shaping component 31 and the fixed shaping component 32, the steel ball rotates while revolving along the fixed shaping component 32, until the steel ball is shaped and moves out from between the rotary shaping component 31 and the fixed shaping component 32 and falls into the guide trough 33;

[0054] During this process, the adjustable heavy pressure component 43 presses down the hydraulic oil in the buffer cylinder 41, and the pressure of the hydraulic oil in the buffer cylinder 41 pushes the displacement compensation component 42; the displacement compensation component 42 provides displacement compensation to the fixed shaping component 32 and squeezes it at the same time, so that while providing displacement compensation for the fixed shaping component 32, it prevents the steel ball from getting stuck and always provides a constant pressure for the steel ball, so that the shaping process is smoother and more uniform;

[0055] At the same time, before use, the gravity of the adjustable weight-pressing component 43 can be changed according to the requirements of the shaping strength, so as to adapt to the shaping requirements of different precisions; and the adjustable weight-pressing component 43 applies pressure to the hydraulic oil in the buffer cylinder 41 by its own gravity, and the gravity of the adjustable weight-pressing component 43 remains unchanged, and the pressure of the hydraulic oil in the buffer cylinder 41 remains unchanged, so that the thrust of the hydraulic oil in the buffer cylinder 41 on the displacement compensation component 42 remains unchanged; thereby avoiding the occurrence of insufficient pressure due to spring fatigue, thereby affecting the shaping quality;

[0056] During the shaping process, the overall displacement of the fixed shaping component 32 and the displacement compensation component 42 changes slightly, and the displacement compensation component 42 moves through the buffer cylinder 41 to drive the adjustable heavy pressure component 43 to move synchronously, and the displacement of the adjustable heavy pressure component 43 is much larger than that of the displacement compensation component 42, so that the displacement of the displacement compensation component 42 can be calculated by detecting the displacement of the adjustable heavy pressure component 43 through the monitoring mechanism 5, thereby improving the monitoring accuracy;

[0057] When the size of the steel ball to be shaped meets the standard and the displacement changes of the fixed shaping component 32 and the displacement compensation component 42 are small, the monitoring mechanism 5 will not start; when the size of the steel ball to be shaped exceeds the standard, the monitoring mechanism 5 will start automatically; the monitoring mechanism 5 monitors the displacement of the adjustable heavy pressure component 43 to determine whether there is a deviation in the size of the steel ball entering between the rotary shaping component 31 and the fixed shaping component 32, and the corresponding deviation difference range; thereby facilitating timely detection of faults and timely resolution, thereby preventing steel balls with large size deviations from damaging the shaping device; and at the same time preventing the monitoring mechanism 5 from always being in a monitoring state, causing fatigue and affecting the overall service life.

[0067] In this embodiment, when the shaping mechanism 3, the hydraulic buffer mechanism 4 and the monitoring mechanism 5 work normally, different numbers of gravity blocks 436 are placed on the upper side of the supporting plate 434 according to the shaping accuracy requirements, and the gravity blocks 436 are limited by the sliding rod 435; the gravity blocks 436 press down the second piston rod 431 through the supporting plate 434, and the second piston rod 431 moves vertically under the guidance of the guide rod 433, thereby driving the second piston 432 to move vertically in the vertical chamber 414; the second piston 43 2. Press the hydraulic oil downward, so that the hydraulic oil pushes the first piston 423 in the transverse cavity 413 to move horizontally, and the first piston 423 drives the first piston rod 422 to move horizontally, thereby driving the fixed disk shaft 322 to move horizontally through the heat insulation block 421, and the fixed disk shaft 322 pushes the fixed disk 321 to move horizontally under the support and limit action of the sliding support seat 323, thereby pushing the fixed shaping ring 324 to move horizontally, until the fixed shaping ring 324 fits with the rotating shaping ring 314 and is blocked by the rotating shaping ring 314;

[0068] The driving mechanism 2 is started, and the driving mechanism 2 drives the rotating disk 312 to rotate through the rotating disk shaft 311, thereby driving the rotating shaping ring 314 to rotate; the steel ball in the high temperature state is introduced into the annular groove formed by the fixed shaping groove 3241 and the rotating shaping groove 3141 through the introduction cavity 3242, and the steel ball is blocked by the partition plate 3243 and rotates under the drive of the rotating shaping ring 314. , so that the support of the steel ball by the rotating shaping groove 3141 is asymmetrical up and down, so that the steel ball can rotate while revolving around the fixed shaping groove 3241; in this process, the protruding part of the steel ball is squeezed by the rotating shaping ring 314 and the fixed shaping ring 324, and when the protruding part on the steel ball contacts the rotating shaping groove 3141 and the fixed shaping groove 3241, the steel ball pushes the fixed shaping ring 324 to move left, and the fixed shaping ring 324 drives the fixed plate 321 and the fixed The fixed plate shaft 322 moves to the left; the fixed plate shaft 322 pushes the first piston rod 422 and the first piston 423 to move in the horizontal chamber 413 through the insulation block 421, thereby applying pressure to the hydraulic oil in the horizontal chamber 413 and pushing the second piston rod 431 and the second piston 432 to move upward in the vertical chamber 414, thereby pushing the supporting plate 434 and the gravity block 436 on the upper side of the supporting plate 434 to move upward; at the same time, the gravity of the supporting plate 434 and the gravity block 436 on the upper side of the supporting plate 434 reacts on the supporting plate 434 through the hydraulic oil, forming a thrust on the first piston 423, the first piston rod 422, and the insulation block 421, so that the fixed plate shaft 322 and the fixed plate 321 always push the fixed shaping ring 324 to approach the rotating shaping ring 314, always maintain pressure on the steel ball, and squeeze the protruding part of the steel ball; avoid the situation of insufficient thrust due to spring fatigue, thereby ensuring the shaping quality and shaping strength;

[0069] Until the rotating shaping ring 314 drives the steel ball to move to the outlet groove 3245, the steel ball falls into the guide groove 33 through the outlet groove 3245 and the outlet cavity 3244, and the shaping is completed;

[0070] The moving distance of the fixed shaping ring 324 is made consistent with the moving distance of the first piston 423 through the first piston rod 422, the heat insulation block 421, the fixed disk 321 and the fixed disk shaft 322. The movement of the first piston 423 in the horizontal chamber 413 pushes a certain volume of hydraulic oil to move leftward, thereby pushing an equal volume of hydraulic oil into the vertical chamber 414, thereby pushing the second piston 432 and the second piston rod 431 to move upward; the cross-sectional area of ​​the vertical chamber 414 is much larger than the cross-sectional area of ​​the horizontal chamber 413, so that the moving distance of the second piston 432 in the horizontal chamber 413 is much larger than the moving distance of the second piston 432 in the vertical chamber 414;

[0071] Through the coordination of the various structures, the movement of the second piston 432 is synchronized with the movement of the fixed shaping ring 324, and the vertical movement distance of the second piston 432 is much greater than the horizontal movement distance of the fixed shaping ring 324; thus, the movement of the fixed shaping ring 324 can be monitored by monitoring the movement of the second piston 432, and the minute movement of the fixed shaping ring 324 is amplified by the second piston 432 for monitoring, so that the monitoring is more accurate;

[0072] The second piston 432 drives the supporting plate 434 to move vertically through the second piston rod 431, thereby driving the gravity block 436 on the upper side of the supporting plate 434 to move vertically synchronously; the supporting plate 434 drives the mounting plate 55, the conductive block 56 and the conductive spring 57 to move vertically; the conductive spring 57 is always in contact with the insulating cylinder 52 and the resistance wire coil 53 through the ball at the end;

[0073] When the size of the steel ball meets the standard, the horizontal movement distance of the fixed shaping ring 324 is always in a small range, and the vertical movement distance of the supporting plate 434 is small at this time; the conductive spring 57 is only in contact with the insulating cylinder 52 during the entire shaping stage, and the conductive spring 57 is not in contact with the resistance wire coil 53, so that the circuit including the conductive spring 57 and the resistance wire coil 53 is disconnected as a whole;

[0074] If the size of the steel ball exceeds the standard, the corresponding fixed shaping ring 324 will move horizontally for a large distance, and during the shaping process, the supporting plate 434 will be pushed to move vertically upward for a large distance, thereby driving the conductive spring 57 to move upward, so that the steel ball at the end of the conductive spring 57 contacts the resistance wire coil 53, so that the circuit including the conductive spring 57 and the resistance wire coil 53 is connected; the circuit current is monitored by a multimeter, and whether the size of the steel ball to be shaped meets the standard is judged according to the existence of the current signal; if the size of the steel ball exceeds the standard, the displacement of the supporting plate 434 is large, and the multimeter monitors the circuit current. The operator can check the size data of the steel ball to be shaped in time according to the situation to judge whether the front-end process is normal.

[0075] At the same time, the change in the moving distance of the support plate 434 during the entire shaping process can be determined according to the change in the current strength, and then the range of the size of the steel ball can be determined;

[0076] Therefore, when the shaping device is working normally, the monitoring device will not be started, and when the shaping device is working abnormally, the monitoring will be automatically started, thereby preventing the monitoring device from being in a monitoring state all the time, causing fatigue and affecting the overall service life.

[0077] Embodiment 3: In some embodiments, Figure 1-Figure 9 As shown, as a preferred embodiment of the present invention, a method for using a steel ball shaping device with a displacement compensation function comprises the following steps:

[0078] Step 1: According to the shaping accuracy requirements, different numbers of gravity blocks 436 are placed on the upper side of the supporting plate 434, and the gravity block 436 is limited by the sliding rod 435; the gravity block 436 presses down the second piston rod 431 through the supporting plate 434, and the second piston rod 431 moves vertically under the guidance of the guide rod 433, thereby driving the second piston 432 to move vertically in the vertical chamber 414; the second piston 432 presses down the hydraulic oil, so that the hydraulic oil pushes the first piston 423 in the transverse chamber 413 to move horizontally, and the first piston 423 drives the first piston rod 422 to move horizontally, thereby driving the fixed disk shaft 322 to move horizontally through the insulation block 421, and the fixed disk shaft 322 pushes the fixed disk 321 to move horizontally under the support and limiting action of the sliding support seat 323, thereby pushing the fixed shaping ring 324 to move horizontally until the fixed shaping ring 324 fits with the rotating shaping ring 314 and is blocked by the rotating shaping ring 314;

[0079] Step 2: Start the driving mechanism 2, which drives the rotating disk 312 to rotate through the rotating disk shaft 311, thereby driving the rotating shaping ring 314 to rotate;

[0080] Step 3: The steel ball in a high temperature state is introduced into the annular groove formed by the fixed shaping groove 3241 and the rotating shaping groove 3141 through the introduction cavity 3242. The steel ball is blocked by the partition 3243 and rotates under the drive of the rotating shaping ring 314. Through the setting of the rotating shaping groove 3141 and the fixed shaping groove 3241, the rotating shaping groove 3141 supports the steel ball asymmetrically up and down, so that the steel ball can rotate while revolving around the fixed shaping groove 3241. In this process, the protruding part on the steel ball contacts the rotating shaping groove 3141 and the fixed shaping groove 3241, and the steel ball pushes the fixed shaping ring 324 to move to the left, and the fixed shaping ring 324 drives the fixed disk 321 and the fixed disk shaft 322 to move to the left.

[0081] Step 4: The fixed disk shaft 322 pushes the first piston rod 422 and the first piston 423 to move in the horizontal chamber 413 through the heat insulation block 421, thereby applying pressure to the hydraulic oil in the horizontal chamber 413 and pushing the second piston rod 431 and the second piston 432 to move upward in the vertical chamber 414, thereby pushing the support plate 434 and the gravity block 436 on the upper side of the support plate 434 to move upward; if the size of the steel ball meets the standard, proceed to step 5; if the size of the steel ball exceeds the standard, proceed to step 6;

[0082] Step 5: The supporting plate 434 drives the mounting plate 55, the conductive block 56 and the conductive spring 57 to move vertically; the conductive spring 57 is always in contact with the insulating tube 52 and the resistance wire coil 53 through the ball at the end; the horizontal movement distance of the fixed shaping ring 324 is always in a small range, and the vertical movement distance of the supporting plate 434 is small at this time; the conductive spring 57 is only in contact with the insulating tube 52 during the entire shaping stage, and the conductive spring 57 is not in contact with the resistance wire coil 53, so that the circuit including the conductive spring 57 and the resistance wire coil 53 is disconnected as a whole;

[0083] Step 6: The horizontal movement distance of the fixed shaping ring 324 is relatively large, and the supporting plate 434 is pushed to move vertically upward by a relatively large distance during the shaping process, thereby driving the conductive spring 57 to move upward, so that the steel ball at the end of the conductive spring 57 contacts the resistance wire coil 53, so that the circuit including the conductive spring 57 and the resistance wire coil 53 is connected; the circuit current is monitored by a multimeter, and whether the size of the steel ball to be shaped meets the standard is judged according to whether the current signal exists, and the range of the steel ball size exceeding the standard is judged according to the size of the current signal;

[0084] Step 7: When executing step 4, step 5 or step 6, the gravity of the support plate 434 and the gravity block 436 on the upper side of the support plate 434 reacts to the support plate 434 through the hydraulic oil, forming a thrust on the first piston 423, the first piston rod 422, and the insulation block 421, so that the fixed disk shaft 322 and the fixed disk 321 always push the fixed shaping ring 324 to approach the rotating shaping ring 314, always maintain pressure on the steel ball, and squeeze and shape the protruding part of the steel ball; until the rotating shaping ring 314 drives the steel ball to move to the outlet groove 3245, the steel ball falls into the guide groove 33 through the outlet groove 3245 and the outlet cavity 3244 to complete the shaping.
