Description

Technical Field

[0001] The utility model belongs to the technical field of hose core pulling, in particular to a steel core hydraulic hose core pulling device. Background Art

[0002] Hydraulic hoses, also known as hydraulic oil hoses, hydraulic hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure hoses, wire braided hoses, and wire-wound hoses, are generally divided into wire braided hydraulic hoses and wire-wound hydraulic hoses. Most existing hydraulic hoses use a cored production method, which typically involves applying a release agent to the core mold for core removal. The core is then coated with inner rubber, braided, and then covered with outer rubber. Finally, the core mold is removed to form the hose. Existing core-pulling devices are relatively simple in structure, primarily consisting of a pull-and-pull mechanism that is unable to limit or secure the outer circumference of the hose.

[0003] Publication number CN215283328U describes a steel-core hydraulic hose core-pulling device. Through the interaction of a clamping mechanism, a support block, and a through-hole, the device can define the positions of the two ends of the hydraulic hose, reducing the space for movement at both ends and preventing the hose from swinging during the core-pulling process. When the core-pulling machine pushes the steel core to the minimum stroke of the electric telescopic rod, the electric telescopic rod, movable block, one-way cylinder, and clamping plate interact to pull the steel core. This device can operate simultaneously with the core-pulling machine, achieving the core-pulling purpose. However, it still lacks a structure to secure the hose. Utility Model Content

[0004] The purpose of the utility model is to provide a core pulling device for a steel core hydraulic hose to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel core hydraulic hose core pulling device, comprising a base and a platform plate, the platform plate is arranged above the base and a support rod is connected between the bottom and the base, a side plate is provided on the top side of the base, and a clamping ring is fixed on one side of the side plate, a linear motor is embedded on one side of the top of the base, and the moving end of the linear motor is fixed to the side plate, a circular plate is provided at the inner center of the clamping ring, and a plurality of clamping plates are provided on the inner peripheral side of the clamping ring, rectangular sleeves and threaded rods for controlling the movement of the clamping plates are provided on the four sides of the circular plate, a hook is provided on one side of the pull plate, and hinge plates are hinged on both sides of the pull plate.

[0006] In a further embodiment, a protrusion is provided at the bottom of the pull plate, and a sliding groove is provided at the top of the platform plate.

[0007] In a further embodiment, notches are formed on four outer sides of the circular plate, and the notches are adapted to fit the rectangular sleeve.

[0008] In a further embodiment, one end of the rectangular sleeve is connected to the clamping plate, and one end of the rectangular sleeve is threadedly connected to a threaded rod.

[0009] In a further embodiment, a concave cavity is provided in the inner center of the circular plate, and a driving gear and four transmission gears for transmission are provided in the concave cavity.

[0010] In a further embodiment, a limiting sleeve is installed on one side of the top of the platform plate, and a limiting protrusion is provided on the inner side of the limiting sleeve.

[0011] In a further embodiment, two notches are provided on one side of the top of the platform plate, and a double-headed screw is rotatably connected between the inner circumferences of the two notches.

[0012] In a further embodiment, threads are provided at both ends of the outer periphery of the double-headed screw, and a nut seat is provided on the outer periphery of the double-headed screw.

[0013] In a further embodiment, the nut seat and the corresponding side of the pull plate are rotatably connected through a pin fit.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The connection design between the linear motor and the side plate and the movable function of the multiple clamping plates inside the clamping ring are achieved through the threaded connection between the square sleeve and the threaded rod and the meshing transmission between the driving gear and the multiple transmission gears, in conjunction with the connection between the square sleeve and the clamping plates. When the second motor is running, the multiple clamping plates will move synchronously to approach the inner wall of the clamping ring. In this way, the clamping plates and the clamping ring can fix the wall layer of the hose, making it easier to pull the core.

[0016] The adaptability design of the limiting sleeve and the hose, as well as the limiting design of the limiting convex portion on the inner edge of the limiting sleeve, the limited sliding movement of the pull plate and the connection of the pull plate's hook to the core, combined with the symmetrical sleeve arrangement of the double-headed screw and the nut seat and the hinged design at both ends of the hinge plate, can further enable the pull plate to move synchronously when the first motor is running, thereby realizing automatic core pulling;

[0017] The core pulling device for the steel core hydraulic hose can make core pulling more convenient by fixing the wall layer at one end and limiting the position of the other end, combined with automatic core pulling. BRIEF DESCRIPTION OF THE DRAWINGS
