Description

Technical Field

[0001] This utility model relates to the field of continuous extrusion production technology, specifically to a device for automatic winding of synchronous aluminum alloy extrusion wire rods. Background Technology

[0002] Continuous extrusion is a metal forming technology, also known as CONFORM extrusion. When a strip extrusion blank is continuously fed into the inlet of the extrusion cavity, the wheel groove bites the blank under the action of friction and pulls the metal towards the die hole. The friction is enough to generate an extrusion stress of up to 1000 MPa near the die hole, forcing the metal to flow out of the die hole; thus obtaining a continuous strip or wire.

[0003] The continuously extruded bar billets fed in are typically produced by hot extrusion. Hot extrusion uses an extruder to intermittently extrude cast round bars to obtain continuously extruded billets of relatively long lengths. These billets are then wound and collected into coils for use in continuous extrusion. The winding device is usually installed at the rear end of the hot extruder's discharge roller conveyor. It can be a vertical or horizontal drum, driven manually or by an electric motor to simultaneously wind the continuously extruded billets. However, existing winding mechanisms have the following drawbacks: 1. In a vertical drum, the wire accumulates at the bottom of the drum due to gravity during continuous winding, resulting in uneven winding. 2. After winding a coil of wire, a conventional winding device requires transfer. However, due to the high winding tension, the coil tightly wraps around the drum, making it difficult to remove. 3. While a horizontal winding device avoids the accumulation at the bottom of the drum as in a vertical winding device, the single winding position still causes uneven winding across the width of the drum, similarly causing difficulties in subsequent use and transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a device for automatic winding of synchronous aluminum alloy extruded wire rods. The drum can be of variable diameter to eliminate the wrapping force of the wire coil, which is conducive to unloading by the operator. The drum can also be moved left and right to facilitate the uniform winding of the wire at various positions on the drum.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic winding device for synchronous aluminum alloy extruded wire rods is disclosed. The winding device is equipped with a rotating drum. One end of the drum is a drum wall plate with a through hole in the middle, through which a horizontally pullable core rod extends. The drum is formed by multiple wall segments. The front end of each wall segment is hinged to the front end of the core rod via a support rod. The rear end of each wall segment is hinged to the end of the first limb of a three-limb rod via an ear plate. A pulley is installed on the second limb of the three-limb rod. The core rod is fitted with a conical sleeve, and the pulley contacts the conical surface of the conical sleeve. The third limb of the three-limb rod is fixedly connected to a slider, which slides on a slide rail mounted on the drum wall plate.

[0007] When the core rod is pulled back, the surface of the cone sleeve contacts the roller and presses the three limb rods outward, thus expanding the diameter of the wall lobe. At the same time, the slider connecting the three limb rods also slides outward along the divergent and radially arranged slide rails. The slider guides and stabilizes the movement path of the tail end of the wall lobe. In the open state, the connecting rod at the head end of the wall lobe is erected, which also expands the head end of the wall lobe outward. In the open state of the lobe wall, the drum winds up the blank.

[0008] As the core rod advances forward, the three-limb rods lose the contact pressure on the cone sleeve surface, which allows the tail end of the valve wall to retract inward. The connecting rod at the head end of the valve wall also changes from being vertical to being a diagonal brace, reducing its vertical height and also allowing the head end of the valve wall to retract inward.

[0009] The horizontal bars of adjacent tripods are connected at their midpoints by tension springs. The tension springs provide inward tension to the tripods, enabling the valve walls to automatically contract and reduce their diameter without the pressure of the cone sleeve.

[0010] The head end of the mandrel is connected to the piston rod of the pull-out cylinder. The retraction and extension of the mandrel are powered by the cylinder.

[0011] The drum wall panel is fixedly connected to the passive gear, and the passive gear is connected to the driving gear through a chain. The driving gear is driven by a rotating motor through a reduction gearbox. The through hole of the drum wall panel is fixedly connected to the sleeve. The sleeve is mounted on the transverse frame through a bearing. The core rod passes through the center hole of the sleeve and can move freely horizontally.

[0012] The rotation speed of the drum is matched with the production speed of the blank.

[0013] The transverse frame is connected to the transverse track via a sliding block. A bearing seat is provided at the front end of the transverse frame, and the bearing seat is rotatably connected to the end of the lead screw. A wire block is fixedly provided in the middle of the lower part of the transverse frame, and the wire hole of the wire block passes through the lead screw. The other end of the lead screw is driven by a transverse motor.

[0014] Driven by a transverse motor, the transverse frame moves back and forth with the drum, so that the blank wire is evenly wound onto the drum to form a uniform coil.

[0015] Advantages of utility models

[0016] 1. The drum of this utility model can achieve diameter reduction and eliminate the wrapping force of the wire coil, which is conducive to unloading by the operator; when it is necessary to wind up the blank, the wall flaps of the drum expand to adapt to the winding diameter requirements.

[0017] 2. The drum of this utility model can move left and right during the winding process, which is conducive to the wire being evenly wound on various positions of the drum. Attached Figure Description
