Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel ball processing machinery, and particularly relates to a steel ball blank forging positioning and clamping turnover device. BACKGROUND

[0002] In the production process of steel balls, three major categories of casting, hot rolling and forging are usually used, among which forging accounts for a considerable proportion. Compared with casting and hot rolling, the appearance precision and surface quality are better, and the mechanical properties such as metallographic structure, wear resistance and pressure resistance are better, and the service life is long, which is suitable for the processing of large-diameter steel balls such as 80mm, 100mm, 125mm and 150mm. Forging, also known as forging, is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain a forged piece with certain mechanical properties, shape and size.

[0003] The processing technology of steel balls is as follows: the blank (steel bar) is clamped in the air hammer die, and is positioned and supported in the lower die to keep it upright. The upper die is pressed down multiple times to hammer, and when the steel bar is deformed close to a steel ball, the steel ball is rotated and hammered to improve the roundness of the steel ball. Current steel ball forging is mainly manual forging. Due to high labor intensity, each worker can only work continuously for 3-4 hours, so two people are required to work alternately, which is low in work efficiency and high in labor cost. In addition, the forging site is high in dust and noise, and the temperature is as high as 50℃ in summer (there are many 300-500kW high-power electromagnetic heating furnaces on site for heating steel bars). Currently, almost all workers in this industry are over 45 years old, and young people almost no one is interested in it, and it faces the predicament of no one available in a few years. Therefore, an automatic steel ball forging device emerges as the times require to replace manual forging. However, there are several key problems in the current automatic steel ball forging device that affect the quality of the steel ball: 1. The steel bar needs to be coaxial with the upper and lower dies and keep the steel ball upright during forging. However, as the steel bar is gradually hammered, the diameter of the steel bar will become thicker. Therefore, the ordinary centering structure cannot better adapt to the change of the steel bar and follow the centering. Once the steel bar is not in the right position and cannot be coaxial with the die, not only will it cause bending and drumming due to eccentric force, but also will cause local excessive deformation, leading to folding and cracking, and deterioration of organization and performance. In addition, there is an important safety hazard of falling due to the impact of the force on the steel bar, so the centering of the steel bar is more critical. 2. When the steel bar is forged close to a steel ball, the steel ball needs to be rotated at another angle to correct the roundness. However, the current rotation of the steel ball is mostly horizontal rotation, which cannot realize the rotation at another angle and cannot better realize the roundness in all directions. 3. The rotation of the steel ball is generally realized by a single-point contact scissor-type clamp arm. Although this type of clamp arm can realize rotation by two-point support, it cannot accurately rotate the steel ball due to the weight of the steel ball. SUMMARY

[0015] Due to the adoption of the above technical solution, the beneficial effects of the present invention are: I. The billet clamping and turning device includes a billet clamping device, a billet turning device, and a billet turning device. These mechanisms are not independent of each other, but are interconnected and cooperate with each other, as detailed below: (1) During the hammering and straightening process, the billet clamping device and the billet turning device work together to clamp the middle and lower parts of the billet, respectively. Since the billet clamping device and the billet turning device are staggered on the horizontal plane, that is, the clamping directions on the horizontal plane are different and the clamping heights are different, the billet can always be vertical. After each forging, the billet clamping device and the billet turning device have an instantaneous release and clamping action to ensure that the billet is always vertical. As the height of the billet gradually decreases, when it reaches the height of the billet clamping device, the billet clamping device releases and avoids, and only the billet turning device is needed for support. This is because at this time, the two ends of the billet are in spherical contact with the forging die. The spherical contact itself has a positioning effect. At this time, the clamping requirements can be met by the billet turning device alone, ensuring that the billet is vertical. (2) When the height of the billet is forged to be close to the height of the steel ball, the steel ball is turned over. When the steel ball is turned over, the billet rotating device and the billet turning device work together. First, the billet turning device turns and forges vertically, and then rotates horizontally and turns and forges vertically. The horizontal rotation and vertical turning are repeated alternately until the roundness of the steel ball meets the requirements. In summary, by using the combined operation of the above devices, the omnidirectional roundness requirements of the steel ball can be achieved relatively well.

[0016] II. Both the billet turning device and the billet clamping device employ a specially shaped diamond-shaped clamping arm to clamp and straighten the steel bar. The interior of this diamond-shaped clamping arm forms a clamping area, holding the steel bar and steel ball within. This not only provides good safety but also provides four clamping points between the steel bar and steel ball. Through coordinated clamping in four directions, the stability of the steel bar and steel ball clamping is ensured, preventing slippage and deflection, thus guaranteeing the quality of the steel ball forging. In addition to clamping and straightening, the billet turning device can also vertically rotate. This vertical rotation axis is perpendicular to the horizontal rotation axis commonly found in existing technologies, providing a new turning method and a new rotation angle for multi-directional automatic forging of the steel ball, ensuring all-around forging of the steel ball and achieving better all-around roundness.

DETAILED DESCRIPTION

[0018] The application is further described below in conjunction with the drawings and examples. In the following detailed description of the application, certain exemplary embodiments of the application are described by way of illustration only. It will be apparent to those skilled in the art that modifications can be made to the described embodiments without departing from the spirit and scope of the application. Thus, the drawings and description are illustrative only and are not intended to limit the scope of the claims.

[0019] As Figure 1As shown, the full-automatic steel ball blank forging device comprises a blank feeding mechanism 100, a blank transferring mechanism 200, a clamping and turning mechanism 300 and a forging die 400, which are used in cooperation. The forging die 400 comprises an upper die and a lower die, and the upper die and the lower die are both formed with a die cavity. The shape of the die cavity can be determined according to the shape of the pre-deformation of the steel ball, which is spherical and less than 1 / 2 of the whole sphere. The forging die 400 belongs to the prior art, and will not be described here. In use, the blank (steel bar) is conveyed to the front of the blank feeding mechanism 100, the blank transferring mechanism 200 drives the clamping and turning mechanism 300 to move to the upper side of the blank feeding mechanism 100 to wait, when the blank is conveyed to the blank feeding mechanism 100, the blank feeding mechanism 100 transfers the blank to the center of the clamping and turning mechanism 300 in a vertical state, the clamping and turning mechanism 300 clamps the blank, then the blank transferring mechanism 200 transfers the blank to the upper side of the forging die 400, the clamping and turning mechanism 300 is released instantly, the blank falls into the lower die of the forging die 400, then the clamping and turning mechanism 300 positions and supports the steel bar, and then the forging die 400 performs forging work. During the forging process, the clamping and turning mechanism 300 clamps, releases, horizontally rotates and vertically turns according to the state of the blank, until the blank forms a steel ball. In this process, with the cooperation of the controller, the laser displacement sensor and the visual recognition module, the center axis of the positioning ring seat, the center axis of the forging die 400, the center axis of the blank, the height of the blank and the roundness of the steel ball can be fed back, so as to realize the full-automatic forging of the steel ball.

[0020] Referring to Figure 2 and Figure 3 , the blank transferring mechanism 200 comprises a positioning ring seat 201 and a ring seat transferring device. The positioning ring seat 201 is a mounting base of the clamping and turning mechanism 300, which is used to realize stable support and accurate positioning of the clamping and turning mechanism 300. The ring seat transferring device is used to support the positioning ring seat 201 and drive the positioning ring seat 201 to move reciprocally between the blank feeding mechanism 100 and the forging die 400.

[0021] The ring seat transferring device comprises a first linkage mechanism 202, a second linkage mechanism 203 and a third linkage mechanism 204, which are arranged in a circumferential form and are uniformly distributed, outer ends of the first linkage mechanism 202, the second linkage mechanism 203 and the third linkage mechanism 204 are rotatably installed on the support, inner ends of the first linkage mechanism 202, the second linkage mechanism 203 and the third linkage mechanism 204 are connected to the positioning ring seat 201, the first linkage mechanism 202 and the second linkage mechanism 203 each comprise a main joint, a secondary joint rotatably connected to the main joint, a main driving mechanism for driving the main joint to rotate relative to the support, and a secondary driving mechanism for driving the secondary joint to rotate relative to the main joint, the third linkage mechanism 204 comprises a support main joint and a support secondary joint rotatably connected to the support main joint, and three secondary joints are hingedly connected to the outer periphery of the positioning ring seat 201. The three linkage mechanisms are distributed on the outer periphery of the positioning ring seat 201, and cooperate to support to ensure the stability of the positioning ring seat 201, thereby ensuring the overall stability of the clamping and supporting turnover mechanism 300 installed thereon, and further ensuring the positioning accuracy.

[0022] Referring to Figure 4 and Figure 5 , the clamping and supporting turnover mechanism 300 comprises a blank clamping device 310, a blank clamping and supporting device 320, a blank supporting and turning device 330 and a supporting and turning rotating device 340 arranged on the outer periphery of the positioning ring seat 201. The blank clamping device 310, the blank clamping and supporting device 320 and the blank supporting and turning device 330 are arranged in sequence from top to bottom, and the blank clamping and supporting device 320 and the blank supporting and turning device 330 are arranged in a staggered manner in the horizontal plane, and the clamping arms of the blank clamping device 310, the blank clamping and supporting device 320 and the blank supporting and turning device 330 all face the inside of the positioning ring seat 201 and correspond to the central axis of the positioning ring seat 201. The blank clamping device 310 and the blank clamping and supporting device 320 are fixed to the positioning ring seat 201 for clamping and supporting the blank, the blank supporting and turning device 330 is used for supporting the blank and turning the steel ball, the blank supporting and turning device 330 is rotatably installed on the positioning ring seat 201 through the supporting and turning rotating device 340, and the supporting and turning rotating device 340 can drive the blank supporting and turning device 330 to rotate horizontally around the central axis of the positioning ring seat 201.

[0023] The working principle of the clamping and supporting turnover mechanism 300 is as follows: When the blank feeding mechanism 100 lifts the blank upward to the center of the positioning ring seat 201, the blank clamping device 310 first clamps the upper part of the blank, then the blank clamping device 320 clamps the middle part of the blank, and both cooperate to stably clamp the blank, then the positioning ring seat 201 and the clamped blank are moved to the forging die 400 by the ring seat moving device, the axis of the blank is aligned with the center of the forging die 400, then the blank clamping device 310 and the blank clamping device 320 are simultaneously released and clamped, the blank is released and falls into the lower die, then the blank clamping device 330 clamps the lower part, at this time the upper part, the middle part and the lower part of the blank are clamped, then the upper die is lowered to forge the blank, when forging to the blank clamping device 310, the blank clamping device 310 is opened to avoid, and the blank clamping device 310 and the blank clamping device 320 cooperate to clamp the blank; as the blank is continuously forged, when forging to the blank clamping device 320, the blank clamping device 320 is opened to avoid, and only the blank clamping device 330 can clamp, when the height of the blank approaches the steel ball, the blank clamping device 330 rotates the steel ball horizontally and vertically, until the steel ball meets the roundness requirement.

[0024] The blank clamping device 310, the blank clamping device 320, the blank clamping device 330 and the turning device 340 are not independent of each other, but are related and cooperate with each other, as follows: (1) When clamping the blank, the blank clamping device 310 and the blank clamping device 320 cooperate to clamp the upper part and the middle part of the blank, which can ensure that the blank is stably clamped and avoid sliding when moving to the forging die 400 from one side; (2) When initially forging and supporting, the blank clamping device 310, the blank clamping device 320 and the blank clamping device 330 cooperate to clamp the upper part, the middle part and the lower part of the blank, respectively, as shown in Figure 18 (a). This step only supports for 1-2 seconds, which plays a short supporting role in air hammer forging, to ensure the absolute verticality of the blank in the initial forging. After the burrs affecting the verticality at both ends of the blank are forged, the blank clamping device 310 is automatically released and avoided; (3) When subsequent forging and supporting, the blank clamping device 320 and the blank clamping device 330 cooperate to clamp the middle part and the lower part of the blank, respectively, as shown in Figure 18(b). Since the blank clamping device 320 and the blank turning device 330 are staggered in the horizontal plane, that is, the clamping directions of the horizontal plane are different, and the clamping is at different heights, it can be ensured that the blank is always vertical. The blank clamping device 320 and the blank turning device 330 have an instantaneous release and clamping action after each forging, which ensures that the blank is always vertical. As the height of the blank gradually decreases, when it reaches the height of the blank clamping device 320, the blank clamping device 320 is released to avoid it, and only the blank turning device 330 can be supported, because at this time the blank is in spherical contact with the forging die 400, and the spherical contact itself has a positioning effect. At this time, only the blank turning device 330 can meet the clamping requirements to ensure that the blank is vertical; (4) When the height of the blank is forged close to the height of the steel ball, the steel ball starts to turn over (at this time the shape is close to a sphere, but the surface roundness does not meet the requirements, so it is also called a steel ball here), see Figure 18 (c). When the steel ball is turned over, the blank rotating device cooperates with the blank turning device 330 to first vertically turn over and forge, then horizontally rotate, then vertically turn over and forge, and then horizontally rotate and vertically turn over alternately and repeatedly until the roundness of the steel ball meets the requirements, see Figure 18 (d). Taking forging a 150mm steel ball as an example, when the height of the blank is forged to between 152-155mm, the steel ball starts to turn over. First, vertically turn over 60° at the current position, and turn over 3 times, at least forging once for each turn; then horizontally rotate 60°, then vertically turn over 60°, and turn over 3 times, at least forging once for each turn; finally, horizontally rotate 60°, then vertically turn over 60°, and turn over 3 times, at least forging once for each turn. A total of 9 turns and 2 horizontal rotations are completed to form a steel ball, which takes about 30 seconds.

[0025] Referring to Figure 6 , the turning device 340 includes a rotating ring seat 341 coaxially installed on the positioning ring seat 201, the blank turning device 330 is fixed to the rotating ring seat 341, the outer periphery of the rotating ring seat 341 is provided with ring seat peripheral teeth 342, the positioning ring seat 201 is provided with a driving gear matched with the ring seat peripheral teeth 342, and the driving gear is connected to the power end of a rotating power assembly 343. The rotating power assembly 343 includes a motor assembly fixed to the positioning ring seat 201, the power end of the motor assembly is fixedly connected with the driving gear, the driving gear is driven to rotate, thereby driving the rotating ring seat 341 to rotate relative to the positioning ring seat 201, that is, driving the blank turning device 330 to horizontally rotate.

[0026] Referring to Figure 7The blank clamping device 310 is fixed on the positioning ring seat 201, which is used for clamping the blank and has a short supporting effect. The structure is basically the same as that of a common scissor-shaped clamp, which includes two intersecting clamping arms 311. The tail end of the clamping arm 311 is hinged to the end of a clamping telescopic cylinder 313 through a clamping connecting rod 312. When the clamping telescopic cylinder 313 extends and retracts, the clamping arm 311 is closed and opened through the clamping connecting rod 312.

[0027] Referring to Figure 8 and Figure 9 , the blank clamping and supporting device 320 is located above the blank supporting and turning device 330, and the height of the blank supporting and turning device 330 corresponds to the center of the steel ball. Meanwhile, the blank clamping and supporting device 320 and the blank supporting and turning device 330 are arranged in a staggered manner in the horizontal plane. When clamping and supporting, the angle between the blank clamping and supporting device 320 and the blank supporting and turning device 330 is between 45° and 90°, and the optimal angle is 90°. Since the blank supporting and turning device 330 can rotate horizontally relative to the positioning ring seat 201, the angle between the blank clamping and supporting device 320 and the blank supporting and turning device 330 can be changed. Referring to Figure 9 , the arrow direction is a schematic diagram of the horizontal rotation of the blank supporting and turning device 330.

[0028] Referring to Figure 10 to Figure 12 , the blank clamping and supporting device 320 includes a left clamping and supporting arm assembly 320A and a right clamping and supporting arm assembly 320B, which are arranged in a 180° symmetrical manner. The left clamping and supporting arm assembly 320A and the right clamping and supporting arm assembly 320B cooperate and synchronize clamping and releasing. The blank clamping and supporting device 320 is used for clamping and supporting the blank, so that the blank can always be vertical and the forging quality can be improved.

[0029] The left clamping and supporting arm assembly 320A includes a left clamping and supporting arm one 321 and a left clamping and supporting arm two 322, and a left clamping and supporting opening and closing device for driving the left clamping and supporting arm one 321 and the left clamping and supporting arm two 322 to open and close horizontally. The right clamping and supporting arm assembly 320B includes a right clamping and supporting arm one 323 and a right clamping and supporting arm two 324, and a right clamping and supporting opening and closing device for driving the right clamping and supporting arm one 323 and the right clamping and supporting arm two 324 to open and close horizontally. When the blank is in the clamping area, the left clamping and supporting opening and closing device and the right clamping and supporting opening and closing device cooperate and synchronize to drive the left clamping and supporting arm one 321, the left clamping and supporting arm two 322, the right clamping and supporting arm one 323, and the right clamping and supporting arm two 324 to close and open simultaneously, so as to clamp and release the blank.

[0030] The left clamping arm one 321 is hinged with the left clamping arm two 322 and the right clamping arm one 323, the right clamping arm two 324 is hinged with the left clamping arm two 322 and the right clamping arm one 323, the left clamping arm one 321, the left clamping arm two 322, the right clamping arm one 323 and the right clamping arm two 324 form a diamond structure and form a clamping area in the middle, the blank is located in the clamping area, the left clamping opening and closing device and the right clamping opening and closing device cooperate to drive the left clamping arm one 321, the left clamping arm two 322, the right clamping arm one 323 and the right clamping arm two 324 to close at the same time, and the blank is clamped, the state before clamping is shown in Figure 11 , the state after clamping is shown in Figure 12 . During each forging process, the device has an instantaneous release and clamping action, which can adapt to the gradual thickening of the blank and continue to clamp the blank.

[0031] The left clamping arm one 321, the left clamping arm two 322, the right clamping arm one 323 and the right clamping arm two 324 each include a clamping connection part and a clamping part, the four clamping parts form a diamond structure around the clamping area, and the end of each clamping part is provided with a clamping tooth 325 protruding inward corresponding to the clamping area. The clamping tooth 325 protrudes, but the sharp end is rounded to avoid damaging the surface of the blank. The clamping tooth 325 is formed by cutting a gap at the end of the clamping part, so that the clamping tooth 325 protrudes inward. Each clamping tooth 325 protrudes inward to form a clamping point that can contact the surface of the blank. Compared with the two contact points formed by the conventional clamp in the prior art, the clamping point of the present application is formed in four directions of the blank, which can ensure the stability of the clamping of the blank. At the same time, as the height of the blank decreases during forging, the diameter of the blank gradually increases. For ordinary clamps in the prior art, the contact point between the clamp and the blank with varying diameter will also change. However, the clamping tooth 325 of the present application protrudes, so the clamping point does not change regardless of the change in the diameter of the blank, and the clamping tooth 325 is always in contact with the blank. In addition, since the clamping tooth 325 has a tooth-like structure, the clamping effect of the tooth is better than the arc clamping or flat clamping of the ordinary clamp in the prior art, which can greatly improve the clamping stability of the clamp and prevent the blank from slipping or deflecting. See Figure 13 Figure (a) and (b) show the state of the clamping tooth 325 clamping the blank. As can be seen from the comparison, the diameters of the blanks are different, but the clamping tooth 325 is in contact with the surface of the blank for clamping.

[0032] The end of the clamping part of the left clamping arm one 321, the left clamping arm two 322, the right clamping arm one 323 and the right clamping arm two 324 is provided with an arm end plate. The arm end plate of the left clamping arm one 321 is hinged with the arm end plate of the right clamping arm one 323 through a first pin shaft, and the arm end plate of the left clamping arm one 321 is hinged with the arm end plate of the right clamping arm one 323 through a second pin shaft.

[0033] The arm end plate of the left clamping arm one 321 is supported on the arm end plate of the right clamping arm one 323, and the arm end plate of the right clamping arm two 324 is supported on the arm end plate of the left clamping arm two 322; or the arm end plate of the left clamping arm two 322 is supported on the arm end plate of the right clamping arm two 324, and the arm end plate of the right clamping arm one 323 is supported on the arm end plate of the left clamping arm one 321.

[0034] The left clamping arm assembly 320A and the right clamping arm assembly 320B are the same in structure and left-right symmetrical. The left clamping opening and closing device comprises a left clamping mounting seat 326, a left clamping opening and closing shaft seat 327 is slidingly installed on the left clamping mounting seat 326, the left clamping arm one 321 and the left clamping arm two 322 are hinged on the left clamping opening and closing shaft seat 327, and a left clamping driving assembly is further arranged on the left clamping mounting seat 326. The left clamping driving assembly drives the left clamping arm one 321 and the left clamping arm two 322 to relatively rotate to open and close through a left clamping connecting piece.

[0035] The left clamping connecting piece comprises a left clamping sliding block 328, the left clamping sliding block 328 is connected with the left clamping driving assembly, and the two ends of the left clamping sliding block 328 are hinged with a left clamping connecting rod one 329 and a left clamping connecting rod two 3210 at the tail ends of the left clamping arm one 321 and the left clamping arm two 322 respectively. The left driving assembly comprises a left clamping telescopic cylinder 3211 installed on the left clamping mounting seat 326, a left clamping driving block 3212 is fixed at the telescopic end of the left clamping telescopic cylinder 3211, and the left clamping sliding block 328 is fixedly connected with the left clamping driving block 3212. When the left clamping telescopic cylinder 3211 telescopes, the left clamping sliding block 328 reciprocally slides, the left clamping connecting rod one 329 and the left clamping connecting rod two 3210 swing, the left clamping opening and closing shaft seat 327 reciprocally slides, and the left clamping arm one 321 and the left clamping arm two 322 close and open.

[0036] The right clamping arm opening and closing device comprises a right clamping arm mounting seat, a right clamping arm opening and closing shaft seat is slidingly mounted on the right clamping arm mounting seat, and the right clamping arm one 323 and the right clamping arm two 324 are hinged to the right clamping arm opening and closing shaft seat; the right clamping arm mounting seat is further provided with a right clamping arm driving assembly, and the right clamping arm driving assembly drives the right clamping arm one 323 and the right clamping arm two 324 to relatively rotate to open and close through a right clamping arm connecting piece.

[0037] The right clamping arm connecting piece comprises a right clamping arm sliding block, the right clamping arm sliding block is connected with the right clamping arm driving assembly, and right clamping arm connecting rods one and two are hinged to the tail ends of the right clamping arm one 323 and the right clamping arm two 324 at both ends of the right clamping arm sliding block. The right driving assembly comprises a right clamping arm telescopic cylinder mounted on the right clamping arm mounting seat, a right clamping arm driving block is fixed to the telescopic end of the right clamping arm telescopic cylinder, and the right clamping arm sliding block is fixedly connected with the right clamping arm driving block. When the right clamping arm telescopic cylinder is telescopically extended and retracted, the right clamping arm sliding block is driven to reciprocally slide, the right clamping arm connecting rods one and two are swung, the right clamping arm opening and closing shaft seat is reciprocally slid, and the right clamping arm one 323 and the right clamping arm two 324 are closed and opened.

[0038] Referring to Figure 14 to Figure 16 The blank clamping and turning device 330 comprises a left clamping and turning arm assembly 330A and a right clamping and turning arm assembly 330B, the left clamping and turning arm assembly 330A and the right clamping and turning arm assembly 330B are arranged in 180° around symmetry and simultaneously act. The blank clamping and turning device 330 mainly functions to turn over the steel ball and also has a righting effect. The blank clamping and turning device 330 and the blank clamping device 320 have the same structure, that is, the opening and closing mode and principle are the same, but the turning structure is additionally arranged on the basis of the blank clamping device 320.

[0039] The left turning and clamping arm assembly 330A comprises a left turning and clamping arm one 331 and a left turning and clamping arm two 332, and further comprises a left turning and clamping opening and closing device for driving the left turning and clamping arm one 331 and the left turning and clamping arm two 332 to horizontally open and close, and a left clamping arm turning device for driving the left turning and clamping arm one 331 and the left turning and clamping arm two 332 to vertically rotate. The right turning and clamping arm assembly 330B comprises a right turning and clamping arm one 333 and a right turning and clamping arm two 334, and further comprises a right turning and clamping opening and closing device for driving the right turning and clamping arm one 333 and the right turning and clamping arm two 334 to horizontally open and close, and a right clamping arm turning device for driving the right turning and clamping arm one 333 and the right turning and clamping arm two 334 to vertically rotate. The left turning and clamping opening and closing device and the right turning and clamping opening and closing device synchronously act to realize clamping and releasing, and the left clamping arm turning device and the right clamping arm turning device synchronously act to realize vertical turning of the steel ball. However, the rotation of the steel ball in the prior art is only horizontal rotation, and vertical turning cannot be realized. Therefore, the present application designs a clamping arm capable of realizing vertical turning, which can better realize full-range roundness. When the blank and the steel ball are righted and horizontally rotated, the blank turning and clamping device 330 is clamped in a horizontal state, as shown in Figure 17 (a). When the steel ball is turned, the blank turning and clamping device 330 is first left-rotated and inclined, then clamps the steel ball, and finally right-rotated to obtain a larger turning angle and increase the turning efficiency. For example, the left-rotation angle is 30°, and after clamping the steel ball, the right-rotation angle is 60°. At this time, the steel ball can be turned by 60°, as shown in Figure 17 (b), Figure 17 The middle Z-axis is a vertical direction.

[0040] The left turning and clamping arm one 331 and the left turning and clamping arm two 332, and the right turning and clamping arm one 333 are respectively hinged, the right turning and clamping arm two 334 is hinged with the left turning and clamping arm two 332 and the right turning and clamping arm one 333, and the left turning and clamping arm one 331, the left turning and clamping arm two 332, the right turning and clamping arm one 333, and the right turning and clamping arm two 334 form a diamond structure and form a turning and clamping area at the middle part. The turning and clamping area corresponds to the central axis of the positioning ring seat 201, and the blank and the steel ball are located in the turning and clamping area.

[0041] The left turning-over clamping arm 331, the left turning-over clamping arm 332, the right turning-over clamping arm 333 and the right turning-over clamping arm 334 all include a turning-over connecting part and a turning-over clamping part, and the four turning-over clamping parts form a diamond structure around the turning-over clamping area, and the end of the turning-over clamping part is provided with a turning-over clamping tooth 335 corresponding to the turning-over clamping area. The turning-over clamping tooth 335 is protrudingly arranged, but the tip is circularly arc transitioned without biting the blank surface. The turning-over clamping tooth 335 is formed by cutting a avoiding notch at the end of the turning-over clamping part, thereby forming the protruding turning-over clamping tooth 335. Each turning-over clamping tooth 335 is inwardly protruding to form a clamping point which can contact the surface of the blank or the steel ball, and four clamping points can be formed around the blank or the steel ball. Compared with the two contact points formed by the conventional clamp on the blank or the steel ball in the prior art, the blank or the steel ball has clamping points in four directions in the present application, which can ensure the stability of the blank or the steel ball clamping. At the same time, as the height of the blank forging decreases, the diameter of the blank gradually increases. For the ordinary clamp in the prior art, the contact point of the clamp and the blank with varying diameter will also change. However, the turning-over clamping tooth 335 of the present application is protruding, so the clamping point will not change regardless of the change of the diameter of the blank, and the turning-over clamping tooth 335 is always in contact with the blank. In addition, since the turning-over clamping tooth 335 is similar to the structure of a tooth, the clamping effect of the tooth is obviously better than that of the arc surface or the plane clamping in the ordinary clamp in the prior art, which can greatly improve the clamping stability of the clamp and avoid the slipping and deflection of the blank or the steel ball. Referring to Figure 13 The state diagram of the turning-over clamping tooth 335 clamping the blank or the steel ball is shown in (a) and (b). It can be seen from the comparison that the diameters of the blanks are different, but the turning-over clamping tooth 335 is in contact with the surface of the blank or the steel ball for clamping.

[0042] The end of the clamping part of the left turning-over clamping arm 331, the left turning-over clamping arm 332, the right turning-over clamping arm 333 and the right turning-over clamping arm 334 is provided with a clamping arm end plate. The clamping arm end plate of the left turning-over clamping arm 331 and the clamping arm end plate of the right turning-over clamping arm 333 are hingedly connected through a first pin shaft, and the clamping arm end plate of the left turning-over clamping arm 331 and the clamping arm end plate of the right turning-over clamping arm 333 are hingedly connected through a second pin shaft.

[0043] The clamping arm end plate of the left turning-over clamping arm 331 is supported on the clamping arm end plate of the right turning-over clamping arm 333, and the clamping arm end plate of the right turning-over clamping arm 334 is supported on the clamping arm end plate of the left turning-over clamping arm 332; or the clamping arm end plate of the left turning-over clamping arm 332 is supported on the clamping arm end plate of the right turning-over clamping arm 334, and the clamping arm end plate of the right turning-over clamping arm 333 is supported on the clamping arm end plate of the left turning-over clamping arm 331.

[0044] Since the left roll-over clamping arm assembly 330A and the right roll-over clamping arm assembly 330B are identical in structure and symmetrical, only the structure of the left roll-over clamping arm assembly 330A is shown in Figure 15 and Figure 16 The structure of the right roll-over clamping arm assembly 330B is not shown separately.

[0045] Referring to Figure 15 and Figure 16 , the left clamping arm roll-over device includes a left roll-over seat 337 rotatably mounted on the left roll-over mounting seat 336 and a left roll-over driving assembly driving the left roll-over seat 337 to rotate vertically; the right clamping arm roll-over device includes a right roll-over seat rotatably mounted on the right roll-over mounting seat and a right roll-over driving assembly driving the right roll-over seat to rotate vertically. The left roll-over mounting seat 336 serves as the mounting base of the device and is fixed on the rotating ring seat; the left roll-over driving assembly is a left roll-over motor 338 fixed on the left roll-over mounting seat 336; the output end of the left roll-over motor 338 is fixed with the left roll-over seat 337, driving the left roll-over seat 337 to rotate. The right roll-over mounting seat serves as the mounting base of the device and is fixed on the rotating ring seat; the right roll-over driving assembly is a right roll-over motor fixed on the right roll-over mounting seat; the output end of the right roll-over motor is fixed with the right roll-over seat, driving the right roll-over seat to rotate.

[0046] The left supporting and turning opening and closing device comprises a left supporting and turning opening and closing shaft base 339 sliding along the left turning seat 337, and the left supporting and turning clamping arm one 331 and the left supporting and turning clamping arm two 332 are hinged to the left supporting and turning opening and closing shaft base 339; further comprising a left supporting and turning opening and closing driving assembly installed on the left supporting and turning mounting seat 336, which drives the left supporting and turning clamping arm one 331 and the left supporting and turning clamping arm two 332 to rotate to open and close through a left supporting and turning connecting piece; the left supporting and turning connecting piece comprises a left supporting and turning sliding block 3310, which is connected with the left turning seat 337 through a left supporting column 3311, and can rotate and slide relative to the left supporting column 3311, and the two ends of the left supporting and turning sliding block 3310 are respectively hinged with a left supporting and turning connecting rod one 3312 and a left supporting and turning connecting rod two 3313 at the tail ends of the left supporting and turning clamping arm one 331 and the left supporting and turning clamping arm two 332, and a left limiting groove 3314 is further arranged in the left supporting and turning sliding block 3310 and matched with the left supporting and turning opening and closing driving assembly; the left supporting and turning opening and closing driving assembly comprises a left supporting and turning telescopic cylinder 3315 installed on the left supporting and turning mounting seat 336, and a left supporting and turning driving block 3316 is fixed at the telescopic end of the left supporting and turning telescopic cylinder 3315, the left supporting and turning driving block 3316 is inserted into the left limiting groove 3314 of the left supporting and turning sliding block 3310, and the left supporting and turning sliding block 3310 can also rotate relative to the left supporting and turning driving block 3316, and the opening of the left limiting groove 3314 is larger than the left supporting and turning driving block 3316.

[0047] The opening and closing action and the rotating action are independent of each other and do not interfere with each other, and the key structure to ensure that they do not affect each other is the left limiting groove 3314. Since the left supporting and turning driving block 3316 is inserted into the left limiting groove 3314 and can pull the left supporting and turning sliding block 3310 to move along the left supporting column 3311, the opening and closing are realized; when turning, the left supporting and turning sliding block 3310 is rotated, and since the left limiting groove 3314 exists, the left supporting and turning sliding block 3310 will not interfere with the left supporting and turning driving block 3316, and the two do not interfere with each other. When the left supporting and turning telescopic cylinder 3315 is telescoped, the left supporting and turning sliding block 3310 is driven by the left supporting and turning driving block 3316 to reciprocally slide along the left supporting column 3311, so that the left supporting and turning connecting rod one 3312 and the left supporting and turning connecting rod two 3313 swing, not only driving the left supporting and turning opening and closing shaft base 339 to reciprocally slide, but also closing and opening the left clamping supporting clamping arm one 321 and the left clamping supporting clamping arm two 322. When the left turning motor 338 drives the left turning seat 337 to rotate, the left supporting and turning clamping arm one 331, the left supporting and turning clamping arm two 332, the left supporting and turning sliding block 3310, the left supporting and turning connecting rod one 3312, the left supporting and turning connecting rod two 3313 and the left supporting and turning opening and closing shaft base 339 rotate as a whole.

[0048] The right turn-over seat is connected with the right support column through the right support column, and the right support column can rotate and slide relative to the right support column. The tail end of the right support column is hinged with the right support arm one 333 and the right support arm two 334. The right support arm one 333 and the right support arm two 334 are hinged on the right support opening and closing shaft seat which slides along the right turn-over seat. The right support opening and closing driving assembly is installed on the right support mounting seat. The right support opening and closing driving assembly drives the right support arm one 333 and the right support arm two 334 to rotate to open and close through the right support connecting piece. The right support connecting piece includes a right support sliding block. The right support sliding block is connected with the right support column through the right support column. The right support sliding block can rotate and slide relative to the right support column. The two ends of the right support sliding block are respectively hinged with the right support connecting rod one and the right support connecting rod two of the tail end of the right support arm one 333 and the right support arm two 334. The right support sliding block is further provided with a right limiting groove matched with the right support opening and closing driving assembly. The right support opening and closing driving assembly includes a right support telescopic cylinder installed on the right support mounting seat. The telescopic end of the right support telescopic cylinder is fixed with a right support driving block. The right support driving block is inserted into the right limiting groove of the right support sliding block, and the right support sliding block can also rotate relative to the right support driving block. The opening of the right limiting groove is larger than the right support driving block.

[0049] The opening and closing action and the rotating action are independent of each other and do not interfere with each other. The key structure to ensure that they do not affect each other is the right limiting groove. Since the right support driving block is inserted into the right limiting groove and can pull the right support sliding block to move along the right support column, the opening and closing is realized. When the turn-over is performed, the right support sliding block is rotated. Since the right limiting groove exists, the right support sliding block does not interfere with the right support driving block, and the two do not interfere with each other. When the right support telescopic cylinder is telescoped, the right support sliding block is driven by the right support driving block to slide along the right support column reciprocally, so that the right support connecting rod one and the right support connecting rod two swing, not only drive the right support opening and closing shaft seat to slide reciprocally, but also close and open the right support arm one 333 and the right support arm two 334. When the right turn-over motor drives the right turn-over seat to rotate, the right support arm one 333, the right support arm two 334, the right support sliding block, the right support connecting rod one, the right support connecting rod two and the right support opening and closing shaft seat rotate as a whole.
