Description

Technical Field

[0001] This invention relates to the field of steel ball processing machinery, and more particularly to a fully automatic forging device for steel ball blanks. Background Technology

[0002] The manufacturing processes for steel balls typically fall into three main categories: casting, hot rolling, and forging. Forging accounts for a significant proportion of the production process. Compared to casting and hot rolling, forging offers better appearance precision and surface quality, especially in terms of metallographic structure, wear resistance, pressure resistance, and other mechanical properties. It also boasts a longer service life and is suitable for processing large-diameter steel balls of 80mm, 100mm, 125mm, and 150mm. Forging, also known as forging, is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain a forging with specific mechanical properties, shape, and dimensions.

[0003] The steel ball processing technology is as follows: the billet (steel bar) is clamped in an air hammer mold, and kept upright in the lower mold by positioning and support. The upper mold repeatedly presses down and hammers the billet. When the steel bar is deformed and close to the shape of a steel ball, the steel ball is rotated and hammered again to improve its roundness. Currently, steel ball forging is mainly done manually. Due to the high labor intensity, each worker can only work continuously for about 3-4 (half an hour) hours, so two people need to take turns working. This results in low work efficiency and high labor costs. In addition, the forging site is dusty and noisy, and the temperature can reach 50°C in summer (there are multiple 300-500kW high-power electromagnetic heating furnaces on site to heat the steel bars). Currently, almost all workers in this industry are over 45 years old, and there are almost no young people willing to work there. The industry faces the predicament of having no one available in a few years. Therefore, automatic steel ball forging devices have emerged to replace manual forging. However, there are several key issues affecting the quality of steel balls in current automatic steel ball forging devices: First, during steel bar forging, the steel bar needs to be coaxial with the upper and lower dies and the steel ball needs to be kept upright. However, as the steel bar is gradually hammered, its diameter will become thicker. Therefore, ordinary straightening structures cannot adapt well to the changes in the steel bar and follow the straightening. Once the steel bar is not in the correct position and cannot be coaxial with the die, it will not only cause bending and bulging due to force eccentricity, but also cause folding and cracking due to excessive local deformation, as well as deterioration of the structure and properties. At the same time, there is also a significant safety hazard of the steel bar falling due to the impact of the force. Therefore, the straightening of the steel bar is crucial. Second, when the steel bar is forged and approaches the steel ball, the steel ball needs to change its angle to correct its roundness. However, most current steel ball rotations are horizontal, which cannot achieve rotation at other angles and thus cannot achieve good all-around roundness. Third, the rotation of the steel ball generally uses a single-point contact scissor-type clamping arm. This type of clamping arm contacts the surface of the steel ball through a two-point support method. Although rotation can be achieved, due to the weight of the steel ball itself, when the clamping arm holds the steel ball in the air, the steel ball may rotate around the axis formed by the two points, resulting in inaccurate rotation angle. Summary of the Invention

[0027] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] I. The billet tilting and turning device includes a billet clamping device, a billet supporting device, a billet tilting device, and a tilting and turning device. These mechanisms are not independent of each other, but are interconnected and cooperate with each other, as detailed below:

[0029] (1) When clamping the billet, the billet clamping device and the billet support device work together to clamp the upper and middle parts of the billet, which can ensure that the billet is clamped stably and prevent the billet from slipping when it is moved from one side to the forging die.

[0030] (2) During the initial forging and straightening, the billet clamping device, billet supporting device, and billet turning device work together to clamp the upper, middle, and lower parts of the billet, respectively. This step only supports for 1-2 seconds, providing short-term support for air hammer forging to ensure the absolute verticality of the billet in the initial stage of hammering. This is because before forging, there will be burrs at the ends of the billet that affect verticality. After the burrs affecting verticality at both ends of the billet are forged, the billet clamping device automatically releases to avoid them.

[0031] (3) During subsequent hammering and straightening, 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 direction on the horizontal plane is different and the clamping is at different heights, it can ensure that the billet is always 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.

[0032] (4) 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 turning the steel ball, 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.

[0033] In summary, by using the combined operation of the above devices, the omnidirectional roundness requirements of the steel ball can be achieved relatively well.

[0034] 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.

[0058] 400 - Forging Die Detailed Implementation

[0059] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0060] like Figure 1As shown, the fully automatic forging device for steel ball billets includes a billet feeding mechanism 100, a billet transfer mechanism 200, a clamping and flipping mechanism 300, and a forging die 400, which work together. The forging die 400 includes an upper die and a lower die, both of which have cavities. The shape of the cavity can be determined according to the pre-deformation shape of the steel ball, and is spherical but less than half the size of a full sphere. The forging die 400 is existing technology and will not be described in detail here. In use, before the billet (steel bar) is conveyed to the billet feeding mechanism 100, the billet transfer mechanism 200 drives the clamping and flipping mechanism 300 to move directly above the billet feeding mechanism 100 to wait. After the billet is conveyed to the billet feeding mechanism 100, the billet feeding mechanism 100 moves the billet vertically upward to the center of the clamping and flipping mechanism 300, where the clamping and flipping mechanism 300 clamps the billet. Then, the billet transfer mechanism 200 moves it above the forging die 400. The clamping and flipping mechanism 300 releases instantly, and the billet falls into the lower die of the forging die 400. Then, the clamping and flipping mechanism 300 straightens and positions the steel bar, and then the forging die 400 performs the forging operation. During the forging process, the clamping and flipping mechanism 300 clamps, releases, rotates horizontally, and flips vertically according to the state of the billet until the billet forms a steel ball. During this process, with the help of a controller, laser displacement sensor and vision recognition module, feedback can be provided on the central axis of the positioning ring seat, the central axis of the forging die 400, the central axis of the billet, the height of the billet and the roundness of the steel ball, so as to realize the fully automatic forging of the steel ball.

[0061] See Figure 2 and Figure 3 The billet transfer mechanism 200 includes a positioning ring seat 201 and a ring seat transfer device. The positioning ring seat 201 is the mounting base of the clamping and flipping mechanism 300, which is used to achieve stable support and accurate positioning of the clamping and flipping mechanism 300. The ring seat transfer device is used to support the positioning ring seat 201 and drive the positioning ring seat 201 to reciprocate between the billet feeding mechanism 100 and the forging die 400.

[0062] The ring seat transfer device includes a first linkage mechanism 202, a second linkage mechanism 203, and a third linkage mechanism 204. The first linkage mechanism 202, the second linkage mechanism 203, and the third linkage mechanism 204 are evenly distributed in a circumferential shape. The outer ends of the first linkage mechanism 202, the second linkage mechanism 203, and the third linkage mechanism 204 are rotatably mounted on the bracket, and the inner ends of the first linkage mechanism 202, the second linkage mechanism 203, and the third linkage mechanism 204 are respectively connected to the positioning ring seat 201. The first linkage mechanism 202 and the second linkage mechanism 203 respectively include a main joint and a secondary joint rotatably connected to the main joint, a main drive mechanism for driving the main joint to rotate relative to the bracket, and a secondary drive mechanism for driving the secondary joint to rotate relative to the main joint. The third linkage mechanism 204 includes a supporting main joint and a supporting secondary joint rotatably connected to the supporting main joint. The three secondary joints are respectively hinged to the outer periphery of the positioning ring seat 201. Three linkage mechanisms are distributed around the outer periphery of the positioning ring seat 201. The three mechanisms work together to support the positioning ring seat 201 and ensure its stability, thereby ensuring the overall stability of the clamping and flipping mechanism 300 installed on it and further ensuring accurate positioning.

[0063] See Figure 4 and Figure 5 The clamping and flipping mechanism 300 includes a billet clamping device 310, a billet clamping device 320, a billet flipping device 330, and a flipping actuation device 340 disposed on the outer periphery of the positioning ring seat 201. The billet clamping device 310, the billet clamping device 320, and the billet flipping device 330 are arranged sequentially from top to bottom, and the billet clamping device 320 and the billet flipping device 330 are staggered on the horizontal plane. The clamping arms of the billet clamping device 310, the billet clamping device 320, and the billet flipping device 330 all face the inside of the positioning ring seat 201, corresponding to the central axis of the positioning ring seat 201. The billet clamping device 310 and the billet supporting device 320 are respectively fixed on the positioning ring seat 201 for clamping and straightening the billet. The billet turning device 330 is used to straighten the billet and turn the steel ball. The billet turning device 330 is rotatably mounted on the positioning ring seat 201 through the turning device 340. The turning device 340 can drive the billet turning device 330 to rotate horizontally around the central axis of the positioning ring seat 201.

[0064] The working principle of the clamping and tilting mechanism 300 is as follows:

[0065] When the billet feeding mechanism 100 lifts the billet upward to the center of the positioning ring seat 201, the billet clamping device 310 first clamps the upper part of the billet, and then the billet supporting device 320 clamps the middle part of the billet. The two work together to stably clamp the billet. Then, the ring seat transfer device transfers the positioning ring seat 201 and the clamped billet to the forging die 400, aligning the axis of the billet with the center of the forging die 400. Then, the billet clamping device 310 and the billet supporting device 320 simultaneously and instantaneously release the clamping device, releasing the billet and letting it fall downward into the lower die. Then, the billet tilting device... 330 then clamps the lower part, at which point the upper, middle and lower parts of the billet are all clamped. Then the upper die descends to forge the billet. When the forging reaches the billet clamping device 310, the billet clamping device 310 opens to avoid it. The billet clamping device 310 and the billet support device 320 cooperate to clamp the billet. As the billet is continuously hammered, when the forging reaches the billet support device 320, the billet support device 320 opens to avoid it, and only the billet flipping device 330 can hold it. When the height of the billet is close to the steel ball, the billet flipping device 330 rotates the steel ball horizontally and flips it vertically until the steel ball reaches the roundness requirement.

[0066] The billet clamping device 310, billet supporting device 320, billet turning device 330, and turning device 340 are not independent of each other, but are interconnected and cooperate with each other, as detailed below:

[0067] (1) When clamping the billet, the billet clamping device 310 cooperates with the billet clamping device 320 to clamp the upper and middle parts of the billet, which can ensure that the billet is clamped stably and prevent the billet from slipping when it is moved from one side to the forging die 400.

[0068] (2) During the initial forging and straightening, the billet clamping device 310, the billet supporting device 320, and the billet turning device 330 cooperate to clamp the upper, middle, and lower parts of the billet, respectively. See the state below. Figure 19 (a). This step only supports for 1-2 seconds, providing short-term support for air hammer forging to ensure the absolute verticality of the billet in the initial stage of hammering. This is because before forging, there will be burrs at the ends of the billet that affect verticality. After the burrs affecting verticality at both ends of the billet are forged, the billet clamping device 310 automatically releases and avoids them.

[0069] (3) During subsequent hammering and straightening, the billet clamping device 320 and the billet turning device 330 cooperate to clamp the middle and lower parts of the billet respectively, as shown in the figure. Figure 19(b) Because the billet clamping device 320 and the billet tilting device 330 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 kept vertical. After each forging, the billet clamping device 320 and the billet tilting device 330 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 320, the billet clamping device 320 releases and avoids, and only the billet tilting device 330 is needed for support. Because at this time, the two ends of the billet are in spherical contact with the forging die 400, and the spherical contact itself has a positioning effect, the clamping requirements can be met by the billet tilting device 330 alone, ensuring that the billet is vertical.

[0070] (4) When the height of the billet is forged to be close to the height of the steel ball, the steel ball is turned 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 the state. Figure 19 (c) When flipping the steel ball, the billet rotating device cooperates with the billet turning device 330. First, the billet turning device 330 vertically flips and forges the ball, then rotates it horizontally, and then vertically flips and forges it again. The horizontal rotation and vertical flipping are repeated alternately until the roundness of the steel ball meets the requirements. See the attached diagram for the state. Figure 19 (d) Taking the forging of a 150mm steel ball as an example, when the billet height is forged to between 152-155mm, the steel ball needs to be flipped. First, from the current position, it is vertically flipped 60°, and this is repeated 3 times, with at least one forging per flip; then, it is horizontally rotated 60°, and then vertically flipped 60° again, and this is repeated 3 times, with at least one forging per flip; finally, it is horizontally rotated 60°, and then vertically flipped 60° again, and this is repeated 3 times, with at least one forging per flip. A total of 9 flips and 2 horizontal rotations are performed to complete the steel ball forming, which takes approximately 30 seconds.

[0071] See Figure 6 The billet turning device 340 includes a rotating ring seat 341 coaxially rotatably mounted on the positioning ring seat 201. The billet turning device 330 is fixed on the rotating ring seat 341. The outer circumference of the rotating ring seat 341 is provided with ring seat teeth 342. The positioning ring seat 201 is provided with a drive gear that cooperates with the ring seat teeth 342. The drive gear is connected to the power end of the rotation power assembly 343. The rotation power assembly 343 includes a motor assembly fixed on the positioning ring seat 201. The power end of the motor assembly is fixedly connected to the drive gear. By driving the drive gear to rotate, the rotating ring seat 341 is driven to rotate relative to the positioning ring seat 201, that is, the billet turning device 330 is driven to rotate horizontally.

[0072] See Figure 7The billet clamping device 310 is fixed on the positioning ring seat 201. It is used to clamp the billet and also provides short-term support. Its structure is basically the same as that of a common scissor-shaped clamp, including two intersecting clamping arms 311. The tail end of the clamping arms 311 is hinged to the end of the clamping telescopic cylinder 313 through the clamping connecting rod 312. When the clamping telescopic cylinder 313 extends and retracts, it drives the clamping arms 311 to close and open through the clamping connecting rod 312.

[0073] See Figure 8 and Figure 9 The billet clamping device 320 is located above the billet tilting device 330, and the height of the billet tilting device 330 corresponds to the center of the steel ball. The billet clamping device 320 and the billet tilting device 330 are staggered on the horizontal plane. In the clamping and straightening state, the angle of misalignment between the billet clamping device 320 and the billet tilting device 330 is between 45° and 90°, with 90° being optimal. Since the billet tilting device 330 can rotate horizontally relative to the positioning ring seat 201, the angle of misalignment with the billet clamping device 320 will change. See also... Figure 9 In the diagram, the direction indicated by the arrow is a schematic diagram of the horizontal rotation of the billet turning device 330.

[0074] See Figures 10 to 12 The billet clamping device 320 includes a left clamping arm assembly 320A and a right clamping arm assembly 320B, which are arranged symmetrically at approximately 180°. The left and right clamping arm assemblies 320A and 320B work together to clamp and release synchronously. The billet clamping device 320 is used to clamp and straighten the billet, ensuring it remains vertical and improving forging quality.

[0075] The left clamping arm assembly 320A includes a first left clamping arm 321 and a second left clamping arm 322, and also includes a left clamping opening and closing device that drives the first left clamping arm 321 and the second left clamping arm 322 to open and close horizontally; the right clamping arm assembly 320B includes a first right clamping arm 323 and a second right clamping arm 324, and also includes a right clamping opening and closing device that drives the first right clamping arm 323 and the second right clamping arm 324 to open and close horizontally. When the billet is located within the clamping area, the left and right clamping opening and closing devices work in tandem, simultaneously closing and opening the first left clamping arm 321, the second left clamping arm 322, the first right clamping arm 323, and the second right clamping arm 324, thus clamping and releasing the billet.

[0076] The left clamping arm 321 is hinged to the left clamping arm 322 and the right clamping arm 323 respectively. The right clamping arm 324 is hinged to the left clamping arm 322 and the right clamping arm 323. The left clamping arms 321, 322, 323, and 324 form a rhomboid structure and a clamping area in the middle. The billet is located in the clamping area. Through the cooperation of the left and right clamping opening and closing devices, the left clamping arms 321, 322, 323, and 324 are driven to close simultaneously, clamping the billet. The state before clamping is described in the figure. Figure 11 See the clamped state. Figure 12 During each forging process, the device momentarily releases and then clamps the billet, adapting to the billet gradually becoming thicker while continuing to clamp it.

[0077] The left clamping arm 321, the left clamping arm 322, the right clamping arm 323, and the right clamping arm 324 each include a clamping connection part and a clamping holding part. The four clamping holding parts form a rhomboid structure located around the clamping holding area. Each clamping holding part has an inwardly protruding clamping holding tooth 325 at its end corresponding to the clamping holding area. The clamping holding tooth 325 is protruding, but the tip is rounded to avoid damaging the surface of the blank. The clamping teeth 325 are formed by cutting avoidance notches at the ends of the clamping parts, resulting in protruding clamping teeth 325. Each clamping tooth 325 protrudes inward to form a clamping point that can contact the surface of the billet, thus forming four clamping points around the billet. Compared with the two contact points formed on the billet by traditional clamps in the prior art, this application has clamping points in four directions on the billet, which can ensure the stability of billet clamping; at the same time, as the forging height of the billet decreases, the diameter of the billet gradually decreases. As the diameter gradually increases, the contact point between the clamp and the billet changes in conventional clamping techniques. However, in this application, the clamping teeth 325 protrude, ensuring that the clamping point remains constant regardless of the billet's diameter; the clamping teeth 325 are always in contact with the billet. Furthermore, because the clamping teeth 325 have a tooth-like structure, their clamping effect is significantly superior to the arc-surface or flat-surface clamping in conventional clamping techniques, greatly improving the clamping stability and preventing the billet from slipping or deflecting. See also... Figure 13 The diagram shows the state of the billet being held by the clamping teeth 325. From the comparison between (a) and (b), it can be seen that the diameters of the billets are different, but the clamping teeth 325 are in contact with the surface of the billet to hold it.

[0078] The clamping ends of the left clamping arm 321, the left clamping arm 322, the right clamping arm 323, and the right clamping arm 324 are all provided with clamping arm end plates. The clamping arm end plate of the left clamping arm 321 and the clamping arm end plate of the right clamping arm 323 are hinged together by a first pin, and the clamping arm end plate of the left clamping arm 321 and the clamping arm end plate of the right clamping arm 323 are hinged together by a second pin.

[0079] The end plate of the left clamping arm 321 is supported on the end plate of the right clamping arm 323, and the end plate of the right clamping arm 324 is supported on the end plate of the left clamping arm 322; or the end plate of the left clamping arm 322 is supported on the end plate of the right clamping arm 324, and the end plate of the right clamping arm 323 is supported on the end plate of the left clamping arm 321.

[0080] The left clamping arm assembly 320A and the right clamping arm assembly 320B have the same structure and are symmetrical. The left clamping opening and closing device includes a left clamping mounting base 326, on which a left clamping opening and closing shaft seat 327 is slidably mounted. The first left clamping arm 321 and the second left clamping arm 322 are hinged to the left clamping opening and closing shaft seat 327. The left clamping mounting base 326 is also provided with a left clamping drive assembly. The left clamping drive assembly drives the first left clamping arm 321 and the second left clamping arm 322 to rotate relative to each other and open and close through the left clamping connector.

[0081] The left clamping connector includes a left clamping slider 328, which is connected to the left clamping drive assembly. Both ends of the left clamping slider 328 are hinged to the tail ends of the first left clamping arm 321 and the second left clamping arm 322, respectively, via a first left clamping link 329 and a second left clamping link 3210. The left drive assembly includes a left clamping telescopic cylinder 3211 mounted on the left clamping mounting base 326. A left clamping drive block 3212 is fixed to the telescopic end of the left clamping telescopic cylinder 3211, and the left clamping slider 328 is fixedly connected to the left clamping drive block 3212. When the left clamp telescopic cylinder 3211 extends or retracts, it drives the left clamp slider 328 to slide back and forth, causing the left clamp connecting rod 1 329 and the left clamp connecting rod 2 3210 to swing. This not only drives the left clamp opening and closing shaft seat 327 to slide back and forth, but also causes the left clamp clamp arm 1 321 and the left clamp clamp arm 2 322 to close and open.

[0082] The right clamp opening and closing device includes a right clamp mounting base, on which a right clamp opening and closing shaft seat is slidably mounted. The right clamp arm 1 323 and the right clamp arm 2 324 are hinged to the right clamp opening and closing shaft seat. The right clamp mounting base is also provided with a right clamp driving assembly. The right clamp driving assembly drives the right clamp arm 1 323 and the right clamp arm 2 324 to rotate relative to each other and open and close through the right clamp connecting piece.

[0083] The right clamping support connector includes a right clamping support slider, which is connected to the right clamping support drive assembly. Both ends of the right clamping support slider are hinged to the tail ends of right clamping support arm 1 (323) and right clamping support arm 2 (324) respectively, with right clamping support connecting rod 1 and right clamping support connecting rod 2 respectively attached. The right drive assembly includes a right clamping support telescopic cylinder mounted on the right clamping support mounting base. A right clamping support drive block is fixed to the telescopic end of the right clamping support telescopic cylinder, and the right clamping support slider is fixedly connected to the right clamping support drive block. When the right clamping support telescopic cylinder extends or retracts, it drives the right clamping support slider to slide back and forth, causing right clamping support connecting rod 1 and right clamping support connecting rod 2 to swing. This not only drives the right clamping support opening and closing shaft seat to slide back and forth, but also causes right clamping support arm 1 (323) and right clamping support arm 2 (324) to close and open.

[0084] See Figures 14 to 16 The billet turning device 330 includes a left turning clamping arm assembly 330A and a right turning clamping arm assembly 330B. The left turning clamping arm assembly 330A and the right turning clamping arm assembly 330B are arranged symmetrically at approximately 180° and operate simultaneously. The main function of the billet turning device 330 is to turn the steel ball, and it also has a straightening function. The billet turning device 330 has the same structure as the billet clamping device 320, that is, the opening and closing method and principle are the same, but the billet turning device 330 adds a turning structure to the billet clamping device 320.

[0085] The left tilting arm assembly 330A includes a first left tilting arm 331 and a second left tilting arm 332, and also includes a left tilting opening and closing device that drives the first left tilting arm 331 and the second left tilting arm 332 to open and close horizontally, and a left arm flipping device that drives the first left tilting arm 331 and the second left tilting arm 332 to rotate vertically; the right tilting arm assembly 330B includes a first right tilting arm 333 and a second right tilting arm 334, and also includes a right tilting opening and closing device that drives the first right tilting arm 333 and the second right tilting arm 334 to open and close horizontally, and a right arm flipping device that drives the first right tilting arm 333 and the second right tilting arm 334 to rotate vertically. The left and right tilting opening and closing devices operate synchronously to achieve clamping and release. The left and right clamping arm flipping devices operate synchronously to achieve vertical flipping of the steel ball. However, in existing technologies, the steel ball only rotates horizontally and cannot achieve vertical flipping. Therefore, this application designs a clamping arm that can achieve vertical flipping, thus better achieving omnidirectional roundness. When the billet tilting device 330 straightens and rotates the billet and steel ball horizontally, the billet tilting device 330 clamps them in a horizontal state. See [reference needed]. Figure 17 (a) When flipping the steel ball, the billet flipping device 330 first tilts to the left, then clamps the steel ball, and finally rotates to the right to obtain a larger flipping angle and increase flipping efficiency. For example, it first tilts to the left by 30°, clamps the steel ball, and then rotates to the right by 60°, at which point the steel ball can be flipped 60°. See [reference needed]. Figure 17 (b) Figure 17 The Z-axis is the vertical direction.

[0086] The left tilting clamp arm 331 is hinged to the left tilting clamp arm 332 and the right tilting clamp arm 333 respectively. The right tilting clamp arm 334 is hinged to the left tilting clamp arm 332 and the right tilting clamp arm 333. The left tilting clamp arm 331, the left tilting clamp arm 332, the right tilting clamp arm 333, and the right tilting clamp arm 334 form a rhomboid structure and form a tilting clamping area in the middle. The tilting clamping area corresponds to the central axis of the positioning ring seat 201. The billet and the steel ball are located in the tilting clamping area.

[0087] The left tilting clamp arm 331, left tilting clamp arm 332, right tilting clamp arm 333, and right tilting clamp arm 334 each include a tilting connection part and a tilting clamping part. The four tilting clamping parts form a rhomboid structure around the tilting clamping area. The ends of the tilting clamping parts are provided with tilting clamping teeth 335 corresponding to the tilting clamping area. The tilting clamping teeth 335 are protruding, but the tips are rounded to prevent them from biting the surface of the billet. The tilting and clamping teeth 335 are formed by cutting avoidance notches at the ends of the tilting and clamping parts, resulting in protruding tilting and clamping teeth 335. Each tilting and clamping tooth 335 protrudes inward to form a clamping point that can contact the surface of the billet and steel ball, thus forming four clamping points around the billet and steel ball. Compared with the two contact points formed on the billet and steel ball in the conventional clamping technology, this application has clamping points in four directions on the billet and steel ball, which can ensure the stability of the billet and steel ball clamping; at the same time, as the forging height of the billet decreases... As the diameter of the billet gradually increases, the contact point between the clamp and the billet changes with the diameter of ordinary clamps in the prior art. However, the tilting clamping teeth 335 of this application protrude, so the clamping point remains unchanged regardless of the change in the billet diameter; the tilting clamping teeth 335 are always in contact with the billet. Furthermore, because the tilting clamping teeth 335 have a tooth-like structure, the clamping effect is significantly better than that of curved or flat clamping in ordinary clamps in the prior art, greatly improving the clamping stability of the clamp and preventing slippage or deflection of the billet or steel ball. See also Figure 13 The diagram shows the state of the billet and steel ball being clamped by the overturning clamping teeth 335. From the comparison between (a) and (b), it can be seen that the diameter of the billet is different, but the overturning clamping teeth 335 are in contact with the surface of the billet and steel ball to clamp them.

[0088] The clamping ends of the left tilting clamp 331, left tilting clamp 332, right tilting clamp 333, and right tilting clamp 334 are all provided with clamping arm end plates. The clamping arm end plate of the left tilting clamp 331 and the clamping arm end plate of the right tilting clamp 333 are hinged together by a first pin, and the clamping arm end plate of the left tilting clamp 331 and the clamping arm end plate of the right tilting clamp 333 are hinged together by a second pin.

[0089] The end plate of the left tilting clamp arm 331 is supported on the end plate of the right tilting clamp arm 333, and the end plate of the right tilting clamp arm 334 is supported on the end plate of the left tilting clamp arm 332; or the end plate of the left tilting clamp arm 332 is supported on the end plate of the right tilting clamp arm 334, and the end plate of the right tilting clamp arm 333 is supported on the end plate of the left tilting clamp arm 331.

[0090] Since the left tilting arm assembly 330A and the right tilting arm assembly 330B have the same structure and are symmetrical, only Figure 15 and Figure 16 The diagram shows the structure of the left tilting arm assembly 330A, but does not show the structure of the right tilting arm assembly 330B separately.

[0091] See Figure 15 and Figure 16 The left clamping arm tilting device includes a left tilting seat 337 rotatably mounted on a left tilting mounting base 336 and a left tilting drive assembly that drives the left tilting seat 337 to rotate vertically. The right clamping arm tilting device includes a right tilting seat rotatably mounted on a right tilting mounting base and a right tilting drive assembly that drives the right tilting seat to rotate vertically. The left tilting mounting base 336 serves as the mounting base of this device and is fixed to a rotating ring seat. The left tilting drive assembly is a left tilting motor 338, which is fixed to the left tilting mounting base 336. The output end of the left tilting motor 338 is fixed to the left tilting seat 337, driving the left tilting seat 337 to rotate. The right tilting mounting base serves as the mounting base of this device and is fixed to a rotating ring seat. The right tilting drive assembly is a right tilting motor, which is fixed to the right tilting mounting base. The output end of the right tilting motor is fixed to the right tilting seat, driving the right tilting seat to rotate.

[0092] The left-hand tilting and opening / closing device includes a left-hand tilting and opening / closing shaft seat 339 that slides along the left-hand tilting base 337. The first left-hand tilting clamping arm 331 and the second left-hand tilting clamping arm 332 are hinged to the left-hand tilting and opening / closing shaft seat 339. It also includes a left-hand tilting and opening / closing drive assembly mounted on the left-hand tilting mounting base 336. The drive assembly drives the first left-hand tilting clamping arm 331 and the second left-hand tilting clamping arm 332 to rotate relative to each other and open and close via a left-hand tilting connector. The left-hand tilting connector includes a left-hand tilting slider 3310, which is connected to the left-hand tilting base 337 via a left support column 3311. The slider 3310 can rotate and slide relative to the left support column 3311. Both ends of the slider 3310 are connected to… The tail ends of the left tilting arm 1 331 and the left tilting arm 2 332 are respectively hinged to the left tilting connecting rod 1 3312 and the left tilting connecting rod 2 3313. The left tilting slider 3310 is also provided with a left limiting groove 3314 that cooperates with the left tilting opening and closing drive assembly. The left tilting opening and closing drive assembly includes a left tilting telescopic cylinder 3315 installed on the left tilting mounting base 336. The telescopic end of the left tilting telescopic cylinder 3315 is fixed with a left tilting drive block 3316. The left tilting drive block 3316 is inserted into the left limiting groove 3314 of the left tilting slider 3310, and the left tilting slider 3310 can also rotate relative to the left tilting drive block 3316. The opening of the left limiting groove 3314 is larger than the left tilting drive block 3316.

[0093] The opening / closing action and the rotation 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 left limiting groove 3314. Since the left tilting drive block 3316 is inserted into the left limiting groove 3314, it can pull the left tilting slider 3310 to move along the left support column 3311, thereby realizing the opening / closing. When tilting, the left tilting slider 3310 is driven to rotate. Due to the existence of the left limiting groove 3314, the left tilting slider 3310 will not interfere with the left tilting drive block 3316, and the two do not interfere with each other. When the left tilting telescopic cylinder 3315 extends or retracts, the left tilting drive block 3316 drives the left tilting slider 3310 to slide back and forth along the left support column 3311, causing the left tilting connecting rod 1 3312 and the left tilting connecting rod 2 3313 to swing. This not only drives the left tilting opening and closing shaft seat 339 to slide back and forth, but also causes the left clamping arm 1 321 and the left clamping arm 2 322 to close and open. When the left tilting motor 338 drives the left tilting seat 337 to rotate, the left tilting clamping arm 1 331, the left tilting clamping arm 2 332, the left tilting slider 3310, the left tilting connecting rod 1 3312, the left tilting connecting rod 2 3313, and the left tilting opening and closing shaft seat 339 rotate as a whole.

[0094] The right-hand tilting and opening / closing device includes a right-hand tilting and opening / closing shaft seat that slides along the right-hand tilting base. The first right-hand tilting clamping arm 333 and the second right-hand tilting clamping arm 334 are hinged to the right-hand tilting and opening / closing shaft seat. It also includes a right-hand tilting and opening / closing drive assembly mounted on the right-hand tilting mounting base. The drive assembly drives the first right-hand tilting clamping arm 333 and the second right-hand tilting clamping arm 334 to rotate relative to each other and open and close via a right-hand tilting connector. The right-hand tilting connector includes a right-hand tilting slider, which is connected to the right-hand tilting base via a right support column. The slider can rotate and slide relative to the right support column. Both ends of the slider are hinged to the tail ends of the first right-hand tilting clamping arm 333 and the second right-hand tilting clamping arm 334, respectively, with a first right-hand tilting connecting rod and a second right-hand tilting connecting rod. The slider also has a right limiting groove that cooperates with the right-hand tilting and opening / closing drive assembly. The right tilting opening and closing drive assembly includes a right tilting telescopic cylinder mounted on the right tilting mounting base. The telescopic end of the right tilting telescopic cylinder is fixed with a right tilting drive block. The right tilting drive block is inserted into the right limiting groove of the right tilting slider, and the right tilting slider can also rotate relative to the right tilting drive block. The opening of the right limiting groove is larger than the right tilting drive block.

[0095] The opening / closing and rotation actions are independent and do not interfere with each other. The key structure ensuring their non-interference is the right limiting groove. Since the right tilting drive block is inserted into the right limiting groove, it can pull the right tilting slider along the right support column, thus achieving opening and closing. When tilting, the right tilting slider is driven to rotate. Due to the presence of the right limiting groove, the right tilting slider will not interfere with the right tilting drive block, and the two do not interfere with each other. When the right tilting telescopic cylinder extends or retracts, the right tilting drive block drives the right tilting slider to slide back and forth along the right support column, causing the right tilting connecting rod one and right tilting connecting rod two to swing. This not only drives the right tilting opening / closing shaft seat to slide back and forth, but also causes the right clamping arm one 323 and right clamping arm two 324 to close and open. When the right flip motor drives the right flip seat to rotate, the right flip clamp arm 1 333, the right flip clamp arm 2 334, the right flip slider, the right flip connecting rod 1, the right flip connecting rod 2, and the right flip opening and closing shaft seat will rotate as a whole.

[0096] See Figure 18The billet feeding mechanism 100 is located on one side of the billet transfer mechanism 200 and is used to automatically lift and feed the billet to the central axis of the positioning ring seat 201. The billet feeding mechanism 100 includes a support frame, on which a feeding tray 101 is vertically slidably mounted via a guide device. A tray lifting device 102 is provided between the feeding tray 101 and the support frame. A feeding box 103 is provided on one side of the feeding tray 101. The feeding box 103 has a billet feeding groove that opens towards the feeding tray 101. One end of the feeding box 103 near the feeding tray 101 is hinged to the support frame. A box swinging device 104 is provided between the feeding box 103 and the support frame. Before feeding, the feeding tray 103 is tilted and the loading tray 101 is located below the billet feeding trough. After the billet is conveyed into the billet feeding trough, the bottom end of the billet will naturally extend into the loading tray 101. Then the tray swinging device 104 moves, causing the feeding tray 103 to change from tilted to vertical, and the billet is erected in the loading tray 101. Finally, the tray lifting device 102 lifts the loading tray 101 upward to the center of the upper positioning ring seat 201.
