Description

Technical Field

[0001] The utility model relates to the technical field of ring rolling equipment, in particular to a ring rolling production equipment. Background Art

[0002] The vertical ring rolling machine is a kind of equipment used for processing ring forgings. Its working principle is to roll and expand the ring through the cooperation of the main rolling roller and the core roller. When working, the ring is sleeved on the core roller, and the main rolling roller rotates and moves downward. When the main rolling roller contacts the ring, it presses the ring downward while driving the ring to rotate. At the same time, the two holding rollers on both sides of the ring abut against the outer side of the ring, thereby realizing the rolling process of thinning the ring thickness and expanding the diameter.

[0003] During the processing of the ring rolling machine, it is necessary to monitor the changes in the size of the rolled ring at any time so as to accurately grasp and control the rolling process. In the prior art, one of the holding rollers is generally modified to have the function of size measurement. For example, Chinese patent document CN205393418U discloses an automatic vertical ring rolling machine, in which a rolling mechanism is provided on the top of the machine body, a rolling wheel is connected to the lower end of the rolling mechanism through a bracket, the bracket is connected to the machine body through an inner guide rail, the rolling wheel can move up and down under the drive of the rolling mechanism, a core roller is provided on the machine body below the rolling wheel, a driving reducer is provided at the tail of the machine body, the driving reducer is connected to the rolling wheel through a universal drive shaft, and a signal roller device and a thrust roller device are respectively provided on the machine body on both sides below the core roller. During operation, the core roller, the rolling wheel, the rollers on the rollers and the thrust roller device roll the ring at the same time, and the measuring component on the signal roller device measures the outer diameter of the ring in real time and changes the rolling speed. When the outer diameter of the ring reaches the target value, the rolling is completed. The rolling wheel, roller and thrust roller device retreat to the initial position, thus completing the rolling process. In this technical solution, although the signal roller device and the thrust roller device are still installed on both sides of the core roller, the signal roller device does not participate in the rolling process of the ring. During the rolling process, the thrust roller always applies a certain thrust to the ring, while the signal roller does not apply the same thrust, which causes the forces on the two sides of the ring to be asymmetric, and the deformation of the two sides of the ring during the rolling process is uneven, resulting in the signal roller being unable to accurately measure the displacement of the side of the rolled ring; in addition, as the rolling process proceeds, the inner diameter and outer diameter of the ring gradually increase, and the signal roller cannot always align with the center of the ring, so it is impossible to accurately monitor the changes in the size of the rolled ring.

[0004] Therefore, how to provide a ring rolling production equipment that can make the deformation of the ring more uniform and can continuously and accurately measure the size of the ring rolling is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0095] In this embodiment, when the first driving member 13 drives the rotating shaft 113 to move axially, the groove 1131 and the convex tooth 1522 slide together, so that the rotating shaft 113 can move freely axially relative to the ring gear 152; when the second driving member 14 drives the rack 153 to move forward and backward, the rack 153 can drive the ring gear 152 meshing with it to rotate, thereby causing the convex tooth 1522 formed on the inner wall of the ring gear 152 to rotate synchronously, and the convex tooth 1522 and the groove 1131 limit each other in the circumferential direction, thereby driving the rotating shaft 113 to rotate.

When the mold clamping structure of this embodiment is in use, the first limiting roller 122 and the second limiting roller 162 are opposite to each other and can be rotated and fitted on the end surfaces of both sides of the ring 900, so that the ring 900 can be limited in the axial direction from both sides at the same time, thereby further eliminating the risk of bending and deformation of the ring.

[0103] The ring rolling production equipment of this embodiment is as follows Figure 10-13 As shown, the continuous measuring device 2 includes a support frame 21, a roller assembly 22, a thrust assembly 23 and a measuring assembly 24; the roller assembly 22 can be vertically lifted and lowered on the support frame 21 through a first mounting structure, and can rotate and fit with the lower surface of the outer ring at the bottom of the ring member; the thrust assembly 23 is supported below the roller assembly 22, and is used to continuously apply a vertical upward thrust to the roller assembly 22, so that the roller assembly 22 can contact and always fit with the lower surface of the outer ring of the ring member, and when the lower surface of the outer ring of the ring member moves downward, it can overcome the thrust of the thrust assembly 23 and make the roller assembly 22 move vertically downward synchronously; the measuring assembly 24 is fixedly mounted on the support frame 21, and is transmission-connected to the roller assembly 22 through a conducting structure, and is used to measure the vertical displacement of the roller assembly 22 from the initial position.

[0104] In this embodiment, the initial position of the roller assembly 22 can be adjusted up and down as needed, so that the continuous measuring device 2 can be suitable for measuring rings of different sizes. In addition, the initial relative position between the roller assembly 22 and the ring can also be set as needed. For example, the roller assembly 22 can be in contact with the lower surface of the outer ring at the bottom of the ring when the ring is in an unprocessed state, so that the roller assembly 22 can completely transmit the dimensional change information of the ring from the beginning of processing to the final forming process to the measuring assembly 24; or, the roller assembly 22 can also not be in contact with the ring when the ring is in an unprocessed state, but only in contact with the lower surface of the outer ring at the bottom of the ring when the diameter of the ring increases to a certain value, so that the dimensional change information of a certain section of the ring processing process can be transmitted to the measuring assembly 24.

[0105] The ring rolling production equipment of this embodiment takes the example that the roller assembly 22 is rotationally fitted with the lower surface of the outer ring at the bottom of the ring when the ring is in an unprocessed state. When in use, the initial position of the roller assembly 22 is adjusted to be rotationally fitted with the lower surface of the outer ring of the ring. As the rolling wheel rolls the ring, the diameter of the ring continues to increase, so that the lower surface of the outer ring of the ring pushes the roller assembly 22 to move downward; because the thrust assembly 23 always applies a vertical upward thrust to the roller assembly 22, the roller assembly 22 can always maintain rotational fit with the lower surface of the outer ring of the ring; during the vertical downward movement of the roller assembly 22, the vertical displacement of the roller assembly 22 from the initial position is transmitted to the measuring assembly 24 through the conduction structure, so that the measuring assembly 24 can measure the dimensional changes of the ring during the entire processing process.

[0106] In this embodiment, since the roller assembly 22 always rolls in contact with the lower surface of the outer ring of the ring, the thrust of the ring applied to the roller assembly 22 is always vertically downward, and the moving direction of the roller assembly 22 is also vertically downward, thereby avoiding measurement deviations caused by the ring swinging left and right, thereby accurately measuring and obtaining the size value of the ring during the processing.

[0107] The ring rolling production equipment of this embodiment, further, the roller assembly 22 includes a mounting seat 221 and a roller 222; the mounting seat 221 includes a base plate 2211 and two supporting plates 2212 vertically oppositely arranged above the base plate 2211; the roller 222 is rotatably connected to the two supporting plates 2212 respectively, the rotating axis of the roller 222 is parallel to the core roller, and the line connecting the centers of the two is in the vertical direction.

[0108] The ring rolling production equipment of this embodiment further includes a first baffle 2213 and a second baffle 2214; the first baffle 2213 is arranged on a side of the bottom plate 2211 away from the ring rolling production equipment, with an upper end fixedly connected to the bottom plate 2211, and a lower end obliquely extending toward a side away from the support frame 21; there are two second baffles 2214, which are relatively arranged on two sides of the bottom plate 2211, with an upper end fixedly connected to the bottom plate 2211, and a lower end obliquely extending toward a side away from the support frame 21.

[0109] In this embodiment, the first baffle 2213 and the second baffle 2214 can block external pollutants to a certain extent.

[0110] In the ring rolling production equipment of this embodiment, the first mounting structure includes a guide sleeve 223 and a guide shaft 224; the guide sleeve 223 is divided into two groups, which are vertically mounted on the support frame 21 opposite to each other on the left and right sides; the guide shaft 224 is divided into two groups, which are arranged opposite to each other on the left and right sides, and are respectively inserted into the two groups of the guide sleeves 223 so as to be movable and retractable, and the upper ends are respectively fixedly connected to the roller assemblies 22, and the lower ends are free ends.

[0111] In this embodiment, the cooperation between the guide shaft 224 and the guide shaft sleeve 223 can prevent the roller assembly 22 from lateral displacement, thereby ensuring that the roller assembly 22 always moves in the vertical direction.

[0112] The ring rolling production equipment of this embodiment further comprises: the guide sleeve 223 comprises an upper sleeve 2231 and a lower sleeve 2232 which are arranged opposite to each other, and a certain distance is spaced between the upper sleeve 2231 and the lower sleeve 2232 so that the guide shaft 224 is partially exposed to the outside of the guide sleeve 223.

[0113] The ring rolling production equipment of this embodiment, further, the transmission structure includes a through groove 2233, a follower rack 251 and a gear 252; the through groove 2233 is vertically arranged on the inner side walls of the upper sleeve 2231 and the lower sleeve 2232 of a group of the guide sleeves 223; the follower rack 251 can be vertically lifted and movably inserted in the through groove 2233, and the tooth surface faces the outside of the guide sleeve 223; the upper end of the follower rack 251 is fixedly connected to the roller assembly 22, and the lower end is a free end; the gear 252 is rotatably mounted on the measuring assembly 24 through the transmission shaft 253, and is meshed with the part of the follower rack 251 located between the upper sleeve 2231 and the lower sleeve 2232.

[0114] In this embodiment, the follower rack 251 is fixedly connected to the roller assembly 22. When the roller assembly 22 moves downward, the follower rack 251 moves downward synchronously with the roller assembly 22, and at the same time drives the gear 252 meshing with the follower rack 251 to rotate synchronously. The number of revolutions of the gear 252 is transmitted to the measuring assembly 24 through the transmission shaft 253. The measuring assembly 24 calculates the displacement of the roller assembly 22 based on the obtained number of revolutions, and further calculates the size value of the ring. In this embodiment, the measuring assembly 24 may include an encoder, and the displacement of the roller assembly 22 can be calculated by the encoder, and the size value of the ring can be calculated.

[0115] The ring rolling production equipment of this embodiment, further, the transmission structure includes a through slot 2233, a follower rack 251 and a gear 252; the through slot 2233 is vertically arranged on the inner side walls of the upper sleeve 2231 and the lower sleeve 2232 of a group of the guide sleeves 223; the follower rack 251 can be vertically lifted and movably inserted in the through slot 2233, with the tooth surface facing the outside of the guide sleeve 223, and the back side fixedly connected with the corresponding guide shaft 224 located inside the guide sleeve 223; the gear 252 is rotatably mounted on the measuring component 24 through the transmission shaft 253, and is meshedly connected with the part of the follower rack 251 located between the upper sleeve 2231 and the lower sleeve 2232.

[0116] In this embodiment, the follower rack 251 is fixedly connected to the corresponding guide shaft 224 located inside the guide sleeve 223. Since the guide shaft 224 is fixedly connected to the roller assembly 22, the displacement of the guide shaft 224 is synchronized with the roller assembly 22, and then the displacement of the follower rack 251 is also synchronized with the roller assembly 22. Therefore, when the roller assembly 22 moves downward, the guide shaft 224 will drive the follower rack 251 to move downward synchronously, and then drive the gear 252 meshing with the follower rack 251 to rotate synchronously, and the number of revolutions of the gear 252 will be transmitted to the measuring assembly 24 through the transmission shaft 253. The measuring assembly 24 calculates the displacement of the roller assembly 22 according to the obtained number of revolutions information, and further calculates the size value of the ring. In this embodiment, the measuring assembly 24 may include an encoder, and the displacement of the roller assembly 22 can be calculated by the encoder, and then the size value of the ring can be calculated.

[0117] The ring rolling production equipment of this embodiment further includes a sleeve 225. The sleeve 225 is divided into two groups and is respectively sleeved on the outer sides of the two groups of guide sleeves 223. A window 2251 is provided on the sleeve 225 corresponding to the group of guide sleeves 223 provided with the through groove 2233, and the window 2251 is opposite to the gear 252 so that the gear 252 can mesh with the follower rack 251 through the window 2251.

[0118] The ring rolling production equipment of this embodiment, further, the thrust assembly 23 includes a cylinder 231 and a piston rod 232; the cylinder 231 is installed on the support frame 21 through a second mounting structure, and can be connected to an external hydraulic oil circuit; the piston rod 232 is telescopically installed in the cylinder 231, and the upper end of the piston rod 232 is fixedly connected to the base plate 2211, for continuously applying a vertical upward thrust to the base plate 2211.

[0119] In this embodiment, the oil pressure of the hydraulic oil introduced into the oil cylinder 231 can be kept constant, so that the thrust of the piston rod 232 on the bottom plate 2211 can be kept constant, thereby reducing the measurement error.

[0120] In the ring rolling production equipment of this embodiment, the second mounting structure includes a mounting plate 233 and a connecting column 234; the mounting plate 233 is a square plate with a through hole in the middle, and the mounting plate 233 is fixedly sleeved on the outside of the cylinder 231; there are four connecting columns 234, which are respectively arranged at the four corners of the mounting plate 233, one end of which is fixedly connected to the mounting plate 233, and the other end is fixedly connected to the bottom plate 2211.

[0121] The working process of the ring rolling production equipment of this embodiment is as follows:

[0122] The first driving member 13 drives the rotating shaft 113 to move away from the body 3 of the ring rolling production equipment, so that the bracket 121 is away from the body 3; the second driving member 14 drives the rotating shaft 113 to rotate, so that the bracket 121 tilts to one side to a deflected state; the ring member 900 is installed on the core roller 32, and one end surface of the ring member 900 is in contact with the second limiting roller 162;

[0123] The second driving member 14 drives the rotating shaft 113 to rotate, so that the bracket 121 returns to an upright state; the first driving member 13 drives the rotating shaft 113 to move toward the direction close to the ring rolling production equipment, so that the free end of the core roller 32 is inserted into the positioning sleeve 126, and the first limiting roller 122 is in contact with the other end surface of the ring member 900;

[0124] The lifting frame 41 is driven downward by the lifting cylinder 442 to roll the ring 900. During the rolling process, the output ends of the two clamping cylinders 53 respectively output the same force to the two driving clamping arms 51, so that the two clamping rollers 52 clamp the two sides of the ring 900 with the same clamping force. At the same time, as the diameter of the ring 900 increases, the lower surface of the outer ring of the ring 900 pushes the roller assembly 22 to move downward, and transmits its vertical displacement from the initial position to the measuring assembly 24 through the conducting structure, so that the measuring assembly 24 can measure the size change of the ring 900.

[0125] When the processing of the ring member 900 is completed, the first driving member 13 drives the rotating shaft 113 to move in the direction away from the machine body 3, so that the bracket 121 is away from the machine body 3; the second driving member 14 drives the rotating shaft 113 to rotate, so that the bracket 121 tilts to one side to a deflected state; then the processed ring member 900 is removed, and the new ring member 900 is installed on the core roller 32 and the above process is repeated.

[0126] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
