Technical Field

[0001] The utility model relates to the technical field of anchor chains, in particular to a crosspiece extrusion device for anchor chain production which can eliminate internal stress. Background Art

[0002] Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grip. It is usually composed of anchor end links, middle links and end links.

[0003] A Chinese patent (Announcement No.: CN211464747U, Announcement Date: 2020.09.11) discloses a device for squeezing crosspieces of an anchor chain unit, including an operating table, and the bottom left and right sides of the operating table are fixedly connected with support legs. The device for squeezing crosspieces of an anchor chain unit is provided with a motor, and the motor is started. The output shaft of the motor drives the rotating shaft to rotate through the coupling, so that the gear is rotated. When the gear rotates forward, the end rod meshing with the gear moves to the opposite side, thereby driving the connecting rod to move to the opposite side. By providing a metal rod, the connecting rod moves to the opposite side to squeeze the connecting rod to move to the opposite side. By providing a fixed block inside the fixed plate, a limiting effect is played, so that the spring moves between the fixed block and the metal rod, so that when the metal rod moves to the opposite side, the pressure of the spring drives the metal rod to move evenly and slowly to the opposite side, thereby reducing the impact rate and achieving the effect of stable positioning. However, since the device cannot change the direction of the anchor chain unit, the limiting plate cannot position all the links on the anchor chain, so that the working efficiency of the device is low.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0016] like Figure 1-2 As shown, the embodiment of the utility model provides a crossbar extrusion equipment for anchor chain production that can eliminate internal stress, including a workbench 1, support legs 2, a first fixed plate 3, a second fixed plate 4, a driving cylinder 5 and a servo motor 15. A limiting groove 14 is provided on the top of the workbench 1, and the servo motor 15 is fixedly connected to the inner wall of the limiting groove 14. The driving end of the servo motor 15 is fixedly connected with a bidirectional threaded rod 16, and the bidirectional threads of the bidirectional threaded rod 16 are both threadedly connected with a movable plate 13. The opposite side walls of the two movable plates 13 are fixedly connected with a clamping plate 12, the bottom of the second fixed plate 4 is fixedly connected with a driving cylinder 5, and the movable end of the driving cylinder 5 is fixedly connected with an extrusion block 6. A pressing plate 7 is arranged below the second fixed plate 4, and a slot 8 is provided through the top of the pressing plate 7, and the extrusion block 6 is located directly above the slot 8.

[0017] The movable plate 13 is slidably connected to the inside of the limiting groove 14, so that the limiting groove 14 can limit the movable plate 13, so that the movable plate 13 can move along the limiting groove 14, the clamping plate 12 is located above the workbench 1, and the side wall of the clamping plate 12 away from the movable plate 13 is arc-shaped. The chain link on the workbench 1 can be clamped by the clamping plate 12, which is convenient for the clamping plate 12 to position the chain link; the top of the pressing plate 7 is fixedly connected to two fixing rods 9, and the two fixing rods 9 are respectively located on both sides of the extrusion block 6. The two side walls of the extrusion block 6 are fixedly connected with connecting plates 10, and the top of the fixing rod 9 The end passes through the connecting plate 10, and the outer surface of the fixing rod 9 is sleeved with a connecting spring 11, and the two ends of the connecting spring 11 are fixedly connected to the bottom of the connecting plate 10 and the top of the pressure plate 7 respectively. Since the connecting spring 11 connects the pressure plate 7 to the connecting plate 10, the pressure plate 7 can compress the connecting spring 11, so that the extrusion block 6 can contact the chain link, and the pressure plate 7 will press the chain link, which is convenient for further positioning of the chain link when the extrusion block 6 processes the chain link; the pressure plate 7 is located directly above the limit groove 14, which is convenient for the pressure plate 7 to level the chain link on the workbench 1.

[0018] Working principle: When using the crossbar extrusion equipment for anchor chain production that can eliminate internal stress, the extrusion block 6 can be driven to move downward by driving the cylinder 5, so that the pressure plate 7 can be driven to move, so that the pressure plate 7 contacts the chain link on the workbench 1. When the driving cylinder 5 drives the pressure plate 7 to continue to move downward, the pressure plate 7 will compress the connecting spring 11, and the compressed connecting spring 11 will apply external force to the pressure plate 7, so that the pressure plate 7 can flatten the chain link, so that the chain link is placed flatly on the workbench 1, which is convenient for the extrusion block 6 to squeeze the crossbar of the chain link, which can improve the efficiency of the anchor chain crossbar extrusion. After the pressure plate 7 flattens the chain link, the servo motor 15 can drive the bidirectional threaded rod 16 to rotate, so that the bidirectional threaded rod 16 can drive the movable plate 13 to rotate, and the movable plate 13 can be rotated. The movable plate 13 slides and is clamped in the limiting groove 14, so that the limiting groove 14 can limit the movable plate 13, so that the movable plate 13 can move along the limiting groove 14, prompting the clamping plate 12 on the movable plate 13 to clamp the flat chain link, which is convenient for the clamping plate 12 to position the chain link and convenient for the extrusion block 6 to process the chain link. When the clamping plate 12 completes the positioning of the first chain link, the driving cylinder 5 continues to drive the pressing plate 7 to move downward, and the compressed connecting spring 11 will cause the pressing plate 7 to press the chain link, which is convenient for further positioning the chain link when the extrusion block 6 processes the chain link. The driving cylinder 5 extrusion block 6 moves downward, and the extrusion block 6 passes through the slot 8 on the pressing plate 7, so that the extrusion block 6 contacts the chain link, so that the extrusion block 6 can perform cross-piece extrusion on the chain link.
