Description

Technical Field

[0001] This invention relates to the field of bearings, and more specifically to a production apparatus for steel plate rubber bearings. Background Technology

[0002] Steel plate rubber bearings are a commonly used type of seismic bearing in the construction industry. Among them, pot bearings are more widely used. During processing, steel plates are usually coated with adhesive. Then, a robotic arm drives a suction cup to stack the rubber plate and steel plate in a mold. The mold is then placed in a flat vulcanizing machine for heating and pressurization to achieve the effect of rubber vulcanization, ultimately making the rubber and steel plate bond into a whole.

[0003] In the existing process, the coating of steel plates, the stacking of steel plates and rubber plates, and the vulcanization of rubber are carried out in different processes and machines. The process also involves the transfer of molds, resulting in a long processing cycle.

[0004] Secondly, the diameter of the mold is generally larger than that of the steel plate and rubber plate. This allows the rubber, after vulcanization and pressurization, to fill around the steel plate and enclose it. However, during the mold transfer process, the positions of the rubber and steel plate inevitably shift, causing them to be out of the center. This results in the steel plate in the final support not being in the center position. The rubber wall of the support on the side where the steel plate is offset is thinner and more prone to damage. In severe cases, it can affect the overall strength of the support later, posing a threat to the safety of the building. Summary of the Invention

[0005] The purpose of this invention is to provide a steel plate rubber bearing production apparatus to solve the problems mentioned in the background art.

[0006] A steel plate rubber bearing production device includes an upper plate, a lower plate, and a driving device. The upper plate and the lower plate are fixedly connected, and a mold is provided between them. A base is provided inside the mold. The driving device is provided on the lower plate. The driving device is used to drive the base to rise and fall. A correction device is provided on the circumference of the mold. When the support plate in the driving device moves to the bottom, the correction device corrects the steel plate and rubber plate in the mold to the center position. When the correction device is not under the action of the support plate, it forms a cylindrical inner cavity with the mold.

[0007] Each side of the mold is provided with a conveyor line, one conveyor line is used to convey steel plates and the other conveyor line is used to convey rubber plates. Each conveyor line is provided with a feeding device at the end. The feeding device is used to push the corresponding steel plates and rubber plates on the conveyor line into the mold. Between the feeding device and the mold, there is a glue applicator for applying glue to the upper surface of the rubber plates and steel plates. A hydraulic press is provided above the mold, and a heating oil channel is also provided inside the mold.

[0008] Preferably, the correction device includes a correction block, a limiting ring, a drive ring, and a pressure plate. The mold has four notches equidistantly spaced around its circumference, each containing a correction block. The limiting ring is fitted onto the outside of the mold, with the correction block located inside the limiting ring. Two positioning posts are fixedly connected to the outside of the correction block, passing through the limiting ring and fixedly connected to the same stop block. A spring is fitted onto the positioning post between the stop block and the limiting ring. A ball bearing is provided on the stop block. The drive ring is fitted onto the outside of the limiting ring, with the ball bearing located inside the drive ring and tangentially contacting the conical surface of the drive ring. Four sliding rods are provided at the bottom of the drive ring, passing through the lower plate and fixedly connected to the pressure plate. A second spring is fitted onto the sliding rod between the drive ring and the lower plate. The correction block has a trapezoidal structure that is wider inside and narrower outside, allowing it to fit tightly against the notches when compressed by internal rubber, providing support to the correction block.

[0009] Preferably, the inner wall of the correction block fills the entire slot, so that the inner wall of the mold is closed into a cylindrical cavity, and the conical surface of the drive ring has a structure that is narrow at the top and wide at the bottom.

[0010] Preferably, the feeding device includes a feeding frame, a limiting frame, and a motor. The motor is fixedly connected to the bottom of the upper plate, and its output shaft is fixedly connected to a gear. The edge of the conveyor line is provided with a limiting frame, and the end of the limiting frame is provided with a sliding groove. One side of the feeding frame is fixedly connected to a rack, and the other side is slidably connected to the sliding groove. The rack meshes with the gear. The feeding frame is disposed on the upper plate, and its bottom surface is in contact with the surface of the upper plate. The feeding frame is divided into two parts: a temporary storage area and a blocking area. The temporary storage area is used to accommodate steel plates and rubber plates, and the blocking area is used to block the end of the conveyor line to prevent the material from continuing to be transported. The side of the temporary storage area facing the conveyor line is provided with a notch for the steel plates and rubber plates to pass through.

[0011] Preferably, the driving device includes an electric push rod located below the pressure plate. The output shaft of the electric push rod is fixedly connected to a support plate. Four support rods are fixedly connected to the support plate. The support rods pass through the lower plate and the mold and are fixedly connected to the lower plate and the mold. The base is located above the support rods.

[0012] Preferably, the glue application device includes a glue box, with a guide post fixedly connected to both ends of the glue box. The top of the guide post passes through a bracket provided on the upper plate and is fixedly connected to a baffle. A spring is sleeved on the guide post between the bracket and the glue box. The bottom of the glue box is provided with a glue outlet, and a glue application roller is rotatably connected inside the glue outlet. The top of the glue box is provided with a connecting groove. A cylinder is also provided on the bracket on one side of the conveying rubber sheet. The output shaft of the cylinder is fixedly connected to a connecting block, which is located in the connecting groove at that location.

[0013] The advantages of this invention are:

[0014] By integrating the vulcanizing unit, feeding unit, and mold into one unit, multiple processes can be completed with a single machine. The planar moving feeding unit is simpler in structure and more efficient than a robotic arm with a suction cup.

[0015] After the material is loaded, the steel plate and rubber plate inside the mold can be corrected by the correction device to make them in the center position of the mold. When the correction block is in the correction state, it also acts as a gap filler, so that it can complete the correction work without affecting the overall structure of the mold, avoiding the previous situation where the steel plate was offset, resulting in a thinner rubber wall on one side.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 6 As shown, a steel plate rubber bearing production device includes an upper plate 1, a lower plate 2, and a driving device 3. The upper plate 1 and the lower plate 2 are fixedly connected, and a mold 4 is provided between them. A base 42 is provided inside the mold 4. The driving device 3 is provided on the lower plate 2. The driving device 3 is used to drive the base 42 to rise and fall. A correction device 5 is provided on the circumference of the mold 4. When the support plate 32 in the driving device 3 moves to the bottom, the correction device 5 corrects the steel plate and rubber plate in the mold 4 to the center position. When the correction device 5 is not acted upon by the support plate 32, it forms a cylindrical inner cavity with the mold 4.

[0028] The mold 4 has a conveyor line 6 on each side, one conveyor line 6 for conveying steel plates and the other conveyor line 6 for conveying rubber plates. Each conveyor line 6 has a feeding device 7 at its end, which pushes the corresponding steel plates and rubber plates on the conveyor line 6 into the mold 4. Between the feeding device 7 and the mold 4, there is a glue applicator 8 for applying glue to the upper surface of the rubber plates and steel plates. A hydraulic press is located above the mold 4 (not shown in the figure). The mold 4 also has a heating oil channel (not shown in the figure).

[0029] In this embodiment, the correction device 5 includes a correction block 51, a limiting ring 52, a driving ring 53, and a pressure plate 54. The mold 4 has four equally spaced notches 41 on its circumference, each notch 41 containing a correction block 51. The limiting ring 52 is fitted onto the outside of the mold 4, with the correction blocks 51 located inside the limiting ring 52. Two positioning posts 511 are fixedly connected to the outside of the correction block 51. The positioning posts 511 pass through the limiting ring 52 and are fixedly connected to the same stop block 512. A spring 55 is fitted onto the positioning post 511 between the stop block 512 and the limiting ring 52. The stop block 512 is provided with a ball bearing 513. The drive ring 53 is sleeved on the outside of the limiting ring 52. The ball bearing 513 is located inside the drive ring 53 and is in tangential contact with the conical surface of the drive ring 53. The bottom of the drive ring 53 is provided with four sliding rods 56. The sliding rods 56 pass through the lower plate 2 and are fixedly connected to the pressure plate 54. A spring 57 is sleeved on the sliding rods 56 between the drive ring 53 and the lower plate 2. The correction block 51 has a trapezoidal structure that is wider inside and narrower outside, so that the correction block 51 can fit tightly against the notch 41 when it is squeezed by the internal rubber. The notch 41 can provide a supporting force to the correction block 51.

[0030] In this embodiment, the inner wall of the correction block 51 fills the entire groove 41, so that the inner wall of the mold 4 is closed into a cylindrical cavity, and the conical surface of the drive ring 53 has a structure that is narrow at the top and wide at the bottom.

[0031] In this embodiment, the feeding device 7 includes a feeding frame 70, a limiting frame 71, and a motor 72. The motor 72 is fixedly connected to the bottom of the upper plate 1, and its output shaft is fixedly connected to a gear 73. The edge of the conveyor line 6 is provided with a limiting frame 71, and the end of the limiting frame 71 is provided with a sliding groove 711. One side of the feeding frame 70 is fixedly connected to a rack 74, and the other side is slidably connected to the sliding groove 711. The rack 74 meshes with the gear 73. The feeding frame 70 is disposed on the upper plate 1, and its bottom surface is in contact with the surface of the upper plate 1. The feeding frame 70 is divided into two parts: a temporary storage area 701 and a blocking area 702. The temporary storage area 701 is used to accommodate steel plates and rubber plates. The blocking area 702 is used to block the end of the conveyor line 6 and prevent the material of the conveyor line 6 from continuing to be transported. The side of the temporary storage area 701 facing the conveyor line 6 is provided with a notch 703 for the steel plate and rubber plate to pass through.

[0032] In this embodiment, the driving device 3 includes an electric push rod 31, which is located below the pressure plate 54. The output shaft of the electric push rod 31 is fixedly connected to a support plate 32. Four support rods 33 are fixedly connected to the support plate 32. The support rods 33 pass through the lower plate 2 and the mold 4 and are fixedly connected to the lower plate 2 and the mold 4. The base 42 is located above the support rods 33.

[0033] In this embodiment, the glue application device 8 includes a glue box 81. A guide post 82 is fixedly connected to both ends of the glue box 81. The top end of the guide post 82 passes through the bracket 83 provided on the upper plate 1 and is fixedly connected to a baffle 84. A spring 85 is sleeved on the guide post 82 between the bracket 83 and the glue box 81. The bottom of the glue box 81 is provided with a glue outlet. A glue application roller 86 is rotatably connected inside the glue outlet. The top of the glue box 81 is provided with a connecting groove 87. A cylinder 88 is also provided on the bracket 83 on the side that conveys the rubber sheet. A connecting block 89 is fixedly connected to the output shaft of the cylinder 88. The connecting block 89 is located in the connecting groove 87 at that location.

[0034] Working process and its principle:

[0035] Hot oil circulates in the heating oil channel inside mold 4, allowing mold 4 to be heated. After the steel plate and rubber plate are processed, they are placed on conveyor line 6 and directly transported to their respective feeding devices 7. The steel plate and rubber plate enter the temporary storage area 701. Then, the feeding device 7, which pushes the rubber plate, works first. The motor 72 starts and drives the feeding frame 70 to move towards mold 4 through gear 73 and rack 74. When passing the glue coating device 8, the thickness of the feeding frame 70 is smaller than that of the corresponding steel plate or rubber plate. The lowest point of the glue coating roller 86 does not contact the feeding frame 70. Only when the steel plate or rubber plate contacts the glue coating roller 86 does the glue box 81 move upward as a whole, the spring 3 85 is compressed, and the glue coating roller 86 comes into close contact with the rubber plate. The rotating glue coating roller 86 applies glue to the rubber plate.

[0036] As the feeding frame 70 continues to move the mold 4, the blocking area 702 at the rear of the feeding frame 70 will move to the end of the conveyor line 6, thereby blocking the rubber plate on the conveyor line 6 from continuing to transport. The rubber plate in the temporary storage area 701 will move to the top of the mold 4. At this time, the upper surface of the base 42 is flush with the upper surface of the mold 4. Then the output shaft of the electric push rod 31 shortens, causing the support plate 32 and the support rod 33 to move down. The base 42 will also descend a certain distance without the support of the support rod 33. The inner side of the upper edge of the mold 4 is chamfered, making the mold 4 opening conical, which facilitates the steel plate and the rubber plate to enter the mold 4. After the rubber plate enters the mold 4, its upper surface is flush with the mold 4.

[0037] Afterwards, the feeding frame 70 that pushes the rubber sheet is reset, and the new rubber sheet enters the temporary storage area 701. The feeding device 7 on the other side is started, and the steel plate is pushed into the mold 4 in the same way. The base 42 also descends accordingly, and the steel plate is stacked on the rubber sheet. This process continues until the last rubber sheet is fed. Since this rubber sheet is the top layer, it does not need to be coated with glue. Therefore, the cylinder 88 will be started this time, and the connecting block 89 will move up, pressing against the connecting groove 87 and moving up, so that the corresponding glue box 81 moves up, preventing the glue roller 86 from contacting the top layer of rubber sheet.

[0038] After all the steel plates and rubber plates are stacked, the output shaft of the electric push rod 31 will move downwards with a large stroke, causing the base 42 to fall back to the bottom of the mold 4. Then, the output shaft of the electric push rod 31 continues to move downwards, causing the support plate 32 to contact the pressure plate 54, which in turn moves the pressure plate 54 downwards. The drive ring 53 moves downwards as well, and the second spring 57 is compressed. The tapered surface, which is smaller at the top and larger at the bottom, acts on the ball 513, causing the baffle to push the positioning post 511 and the correction block 51 to move towards the center. The first spring 55 is compressed, and when the four correction blocks 51 contact the rubber plate and steel plate, they will move towards the center, completing the correction of the rubber plate and steel plate.

[0039] Afterwards, the output shaft of the electric push rod 31 extends, causing the support rod 33 to re-contact the base 42, and the drive ring 53 moves upward and resets under the action of the second spring 57, and the correction block 51 also retracts into the notch 41.

[0040] Subsequently, the hydraulic press drives the pressure mold at its output end to move downward, pressing the rubber plate and steel plate inside the mold 4. Combined with the heated mold 4, the rubber is vulcanized, allowing the rubber to fill the pre-reserved gaps inside the mold 4, thus completing the forming of the support. Finally, the output shaft of the electric push rod 31 extends again, making the upper surface of the base 42 flush with the mold 4 again, and pushing the support out for easy removal.

[0041] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
