Description

Technical Field

[0001] The utility model relates to the technical field of bunching machines, in particular to a cradle assembly of a bunching machine. Background Art

[0002] The bunching machine is applicable to the stranding of aluminum alloy wires, bare copper wires, aluminum stranded steel conductors, sector conductors and cross-linked compacted cable cores with large lengths and large cross-sectional areas. Generally, multiple traction wheels with rotation directions parallel to the incoming wire direction are arranged on the cradle assembly of the existing bunching machine. The traction wheels provide traction force to integrate the stranded cables into one body, improving the mechanical properties and flexibility of the cables. The maximum production wire diameter of the soft copper cable of the existing model 1250 bunching machine is 50 - 70 mm. 2 , when the wire diameter of the cable is larger than this size, due to the traction force problem, it is impossible to ensure the mechanical properties and flexibility of the thick-diameter cable. Therefore, in order to meet the production requirements of thick-diameter cables, the cradle assembly of this bunching machine is designed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a cradle assembly of a bunching machine. By connecting a base at the lower end of the cradle and fixing a traction plate at one end of the base, the traction plate is vertically distributed with the cradle, further making the traction direction of the traction wheel perpendicular to the incoming wire direction, and the traction wheels are vertically distributed, increasing the traction force on the cable and meeting the production requirements of thick-type cables.

[0004] The utility model provides the following technical solution: a cradle assembly of a bunching machine, including a cradle. A base is connected to the bottom of one end of the cradle. The base is used for installing a top cone assembly. A traction plate is connected to the side surface of the base. The traction plate is vertically distributed with the cradle. Two vertically distributed sleeves are formed on the traction plate. The sleeves are used for installing traction wheels. First connecting plates and second connecting plates are fixed on the two side surfaces of the other end of the cradle. The second connecting plate is used for connecting another top cone assembly.

[0005] Further, the cradle includes two side plates. A top plate is connected between the upper ends of the two side plates. A bottom plate is connected between the lower ends of the side plates. The side plates are arched. The upper end of the top plate is arc-shaped, and both ends are vertically distributed. The upper end of the bottom plate is horizontally distributed, and both ends are vertically distributed. The cradle with a frame structure enhances the rigidity and strength of the cradle, and also increases the contact area between the cradle and the incoming wire assembly or the lead wire assembly, making the rotation of the incoming wire assembly and the lead wire assembly smoother.

[0006] Further, the base includes side support plates on both sides and a bottom support plate. One end of the bottom support plate is connected to the traction plate, and the other end of the bottom support plate is connected to one end of the cradle. Installing the top cone assembly through the base ensures the load-bearing capacity of the base and improves the stability of the top cone assembly.

[0007] Furthermore, two grooves are formed on one end face of the second connecting plate. The grooves are used for installing cylinders to control the telescopic position of the top cone assembly. By installing the cylinders through the grooves, the telescopic movement of the top cone assembly is controlled by the cylinders.

[0008] Furthermore, through holes and top cone insertion holes are also formed on the second connecting plate. The through holes are located above the top cone insertion holes, and the top cone insertion holes are located above the grooves.

[0009] Furthermore, two drive shaft connecting plates are fixed on one side plate of the cradle. A drive shaft is rotatably connected between the drive shaft connecting plates. The drive shaft is used to make the incoming wire assembly and the lead wire assembly operate synchronously, ensuring the stability of the wire stranding.

[0010] Furthermore, a reinforcing plate is also fixed on the base. The reinforcing plate is connected to the ends of the bottom plate and the top plate on the same side. The connection strength with the incoming wire assembly is enhanced through the reinforcing plate, making the rotation of the incoming wire assembly smoother.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0012] (1) By connecting a base at the lower end of the cradle and fixing a traction plate at one end of the base, the traction plate is vertically distributed with the cradle, further making the traction direction of the traction wheel perpendicular to the incoming wire direction, and the traction wheels are distributed vertically, increasing the traction force on the wire and meeting the production requirements for thick-type wires.

[0013] (2) By forming a frame-shaped cradle with side plates, a top plate and a bottom plate, the rigidity and strength of the cradle are enhanced, further enhancing the connection strength between the cradle and the top cone assembly, as well as the supporting force for the take-up reel, improving the load-bearing capacity of the take-up reel, and also increasing the contact area with the incoming wire assembly or the lead wire assembly, making the rotation of the incoming wire assembly and the lead wire assembly smoother.
