[0001] This utility model relates to the field of spinning device technology, and more specifically, to a spinning forming device for condenser tube sheets. Background Technology

[0002] Spin forming of condenser tube sheets is a plastic processing technology that uses rotation and pressure to gradually deform a metal sheet, ultimately forming the desired shape of the condenser tube sheet. For example, the spin forming device for end caps proposed in publication number "CN221694914U" includes a base, on which a hydraulic rod and an extrusion block are mounted via a support plate. A rotating body is mounted on the top of the base via a rotating motor. The base also includes a slide rail, a slider, a mounting plate, and a threaded rod. The threaded rod passes through the slider and is threadedly connected to it. A housing is mounted on the inner wall of the mounting plates on both sides, and a pressing block is slidably mounted on the housing. One end of a second spring is connected to the pressing block, and the other end of the second spring is also connected to the pressing block.

[0003] However, in the above technical solution, when the above spinning forming device spins the workpiece, the contact between the pressing block and the iron sheet depends entirely on the elastic deformation of the spring and lacks an active adjustment mechanism. If the thickness of the iron sheet is uneven, the pressing pressure may be unstable, affecting the forming quality. Utility Model Content

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] like Figures 1-7 As shown, a condenser tube sheet spinning forming device includes a base 1, a synchronous motor 2 is fixedly installed on one side of the upper surface of the base 1, and a rotary mold 3 is fixedly installed on the output shaft end of the synchronous motor 2.

[0031] A hydraulic cylinder 5 is fixedly installed on the upper surface of the base 1 via a support frame 4. The output end of the hydraulic cylinder 5 passes through the support frame 4 and is rotatably mounted with a limit block 501.

[0032] Linear motors 6 are provided on both sides of the upper surface of the base 1. Support frames 7 are fixedly installed on the upper surface of the slides of the two linear motors 6. A clamping block 701 is provided at one opposite end of the two support frames 7. An installation groove 702 is opened on one opposite side of the two clamping blocks 701. A lubricating block 703 is slidably arranged in the two installation grooves 702. An elastic telescopic rod 704 is provided on one opposite side of the inner wall of the two installation grooves 702. The movable ends of the two elastic telescopic rods 704 are fixedly connected to the corresponding lubricating blocks 703 respectively.

[0033] Each of the two support frames 7 has an adjustment component 8 on one side for adjustment.

[0034] Adjustment component 8 includes connecting groove 801, which is respectively opened through one side surface of the corresponding support frame 7. A vertical shaft 802 is rotatably installed between the two sides of the inner wall of the connecting groove 801, and an eccentric wheel 803 is sleeved on one side of the shaft of the vertical shaft 802.

[0035] A positioning frame 804 is fixedly installed on one side of the support frame 7. Two sliding rods 805 are slidably arranged through one side of the positioning frame 804. One end of each adjacent sliding rod 805 is fixedly connected to the corresponding clamping block 701.

[0036] The other end of the adjacent slide rods 805 is fixedly installed with a baffle 806, and springs 807 are sleeved on the side of the two slide rods 805 near the baffle 806.

[0037] Worm gears 12 are fitted on the other side of the shafts of the two vertical shafts 802. Worms 13 are rotatably installed between the two sides of the inner wall of the two connecting grooves 801, and the two worm gears 13 mesh with the corresponding worm gears 12 respectively.

[0038] Two servo motors 14 are fixedly installed on one side of the two support frames 7, and one end of each of the two worm gears 13 passes through the support frame 7 and is fixedly connected to the output shaft end of the corresponding servo motor 14.

[0039] The metal sheet to be processed is placed on the rotary mold 3. Then, the operator starts the hydraulic cylinder 5, causing its output end to move the limit block 501, so that the limit block 501 and one end of the rotary mold 3 can clamp the metal sheet. Then, the operator starts the synchronous motor 2, causing its output shaft to drive the rotary mold 3 to rotate at a constant speed, so that the workpiece rotates with the rotary mold 3. Then, the linear motor 6 drives the support frame 7 to move, so that the clamping blocks 701 on both sides are close to the edge of the workpiece. Then, the servo motor 14 drives the worm gear 13 to rotate, driving the worm wheel 12 and the vertical shaft 80. 2. Rotation causes the eccentric wheel 803 to adjust its angle. The protruding part of the eccentric wheel 803 rotates, and under the elastic force of the spring 807, it can adjust the horizontal position of the baffle 806, the slide bar 805, and the clamping block 701, thereby adjusting the clamping force of the clamping block 701 on the workpiece. This ensures that different thickness areas can be stably formed. With the precisely adjustable clamping force and support of the eccentric wheel 803, the clamping block 701 can adapt to different materials or thickness changes. The pressure applied by the clamping block 701 to the surface of the workpiece is stable, ensuring that the forming process is stable and controllable.

[0040] In another embodiment of the present invention, the eccentric wheel 803 includes two semicircular plates 8031, and a semicircular groove 8032 is formed on the opposite side surface of the two semicircular plates 8031.

[0041] Both vertical shafts 802 have annular plates 9 fitted on one side of their shafts, and adjacent semicircular plates 8031 ​​are fixedly mounted on the upper surface of the corresponding annular plates 9 by several fastening bolts 901.

[0042] The eccentric wheel 803 adopts a split structure composed of two semi-circular plates 8031. After the workers quickly disassemble the fastening bolts 901, it is easy to quickly replace the eccentric wheel 803 of different specifications to adapt to different process requirements.

[0043] In another embodiment of this utility model, two positioning blocks 10 are fixedly installed on the shafts of the two vertical shafts 802, and a positioning groove 11 is opened on the inner wall surface of each semi-circular groove 8032. Each positioning block 10 is interlocked with the corresponding positioning groove 11.

[0044] The positioning block 10 is embedded in the corresponding positioning groove 11 to ensure the accurate installation position of the semi-circular plate 8031 ​​and prevent the eccentric wheel 803 from shifting or loosening. Under the support formed by the interlocking cooperation between the positioning groove 11 and the positioning block 10, the cooperation between the positioning block 10 and the positioning groove 11 can share some of the pressure and prevent the eccentric wheel 803 from being damaged by excessive torque.

[0045] In another embodiment of this utility model, two clamping blocks 701 are fixedly mounted with right-angle brackets 15 on opposite sides, and two positioning brackets 804 are provided with tension and compression sensors 16 on their upper surfaces. The detection ends of the two tension and compression sensors 16 are respectively connected to the corresponding right-angle brackets 15.

[0046] A tension / compression sensor 16 is installed on the positioning frame 804, with its detection end directly abutting the right-angle frame 15 to monitor the force state of the clamping block 701 in real time. The sensor detects the radial pressure of the clamping block 701 on the workpiece and converts it into an electrical signal, which is then transmitted to the control system. After receiving the sensor signal, the control system can control the adjustment direction and speed of the servo motor 14. If the workpiece has uneven local thickness, the tension / compression sensor 16 detects that the pressure exceeds the upper limit and triggers the servo motor 14 to reverse, reducing the clamping angle of the eccentric wheel 803. If the tension / compression sensor 16 detects that the pressure is insufficient, it triggers the servo motor 14 to rotate forward, increasing the clamping angle of the eccentric wheel 803.

[0047] Working principle of a condenser tube sheet spinning forming device:

[0048] In use, the metal sheet to be processed is placed on the rotary mold 3. Then, the operator starts the hydraulic cylinder 5, causing its output end to move the limit block 501, so that the limit block 501 and one end of the rotary mold 3 can clamp the metal sheet. Then, the operator starts the synchronous motor 2, causing its output shaft to drive the rotary mold 3 to rotate at a constant speed, so that the workpiece rotates with the rotary mold 3. Then, the linear motor 6 drives the support frame 7 to move, so that the clamping blocks 701 on both sides are close to the edge of the workpiece. Then, the servo motor 14 drives the worm gear 13 to rotate, driving the worm wheel 12 and the vertical shaft. Rotation of 802 causes the eccentric wheel 803 to adjust its angle. The protruding part of the eccentric wheel 803 rotates, and with the elastic force of the spring 807, it can adjust the horizontal position of the baffle 806, the slide bar 805, and the clamping block 701, thereby adjusting the clamping force of the clamping block 701 on the workpiece. This ensures that different thickness areas can be stably formed. With the precisely adjustable clamping force and support of the eccentric wheel 803, the clamping block 701 can adapt to different materials or thickness changes. The pressure applied by the clamping block 701 to the surface of the workpiece is stable, ensuring that the forming process is stable and controllable.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
