Description

Technical Field

[0001] The utility model belongs to the field of hose crimper, and specifically relates to a fire hose crimper. Background Art

[0002] Existing fire hose crimpers all adopt electric or hydraulic drive to realize the crimping of hose connectors.

[0003] Chinese patent with publication number CN212552582U discloses a fire hose crimper, which includes a U-shaped frame. Two support plates are fixedly connected to the upper surface of the U-shaped frame. The top ends of the support plates are fixedly connected with a top plate. A servo motor is fixedly connected to the upper surface of the top plate. The output end of the servo motor is fixedly connected with a lead screw. A connecting plate is threadedly connected to the outside of the lead screw. In the utility model, one end of the connector is placed in the upper die and the lower die on the left side, and the other end of the connector is placed in the upper die and the lower die on the right side. Fire hoses are simultaneously sleeved on both ends of the connector, and a fastening aluminum tube is sleeved at the hinge joint of the fire hose and the connector. Start the servo motor to drive the lead screw to rotate forward. The forward rotation of the lead screw can drive the connecting plate to move downward.
