Description

Technical Field

[0001] This utility model belongs to the technical field of copper drawing equipment, and in particular relates to a rotating eye mold for copper drawing. Background Technology

[0002] Copper drawing refers to a process step in copper processing, specifically the "large drawing" stage in the stretching process of copper rods or wires. This is a common cold drawing process in metal processing, mainly used to process thicker copper rods into thinner copper wires using stretching equipment, while improving the mechanical properties and surface quality of the material. A die is used to cold draw thick copper wire into thin copper wire; rotating the die reduces the resistance during the cold drawing process. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a copper large-scale rotating eye mold mounting structure.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a copper large-diameter rotating eye mold, comprising an outer shell, a rotating sleeve, a pressure head, a sprocket, a first ball bearing, a second ball bearing, and an eye mold. The cages of the first and second ball bearings are fixedly installed in the outer shell. The rotating sleeve is fixedly installed in the rotating body of the first and second ball bearings. The sprocket is fixedly sleeved and installed at the right end of the rotating sleeve. The left end of the rotating sleeve has a receiving hole, the outer end of which is configured as a threaded hole structure. The eye mold is installed in the receiving hole. The pressure head is screwed and fixedly installed in the receiving hole and presses the eye mold tightly and fixedly. The pressure head has a first through hole communicating with the eye mold, and the rotating sleeve is provided with a second through hole communicating with the eye mold.

[0005] The pressure head has notches extending through its left and right ends, and the right end of the pressure head is configured with a V-shaped groove structure.

[0006] Preferably, the outer end of the pressure head has a tool hole.

[0007] Preferably, the outer end of the first through hole and both ends of the second through hole are configured as wide-mouth structures.

[0008] Preferably, the right end of the outer casing has a first flange.

[0009] Preferably, the device also includes a head with a second flange, the second flange of which is screwed and fixedly installed to the first flange, and the head seals the right end of the housing.

[0010] Compared with the prior art, the advantages of this utility model are: the rotating eye mold mounting structure can reduce the resistance of the eye mold to the cold drawing operation of copper wire, and it is easy to push the eye mold out to the left when changing the eye mold. In addition, the V-shaped groove structure of the pressure head and the notch have the characteristic of being able to be squeezed and contracted. Even if the pressure head and the threaded hole of the receiving hole rotate slightly relative to each other, the released compressed V-shaped groove structure can still ensure that the pressure head presses and fixes the eye mold tightly, which has the advantage of high stability in use.

[0016] The present invention will now be described in detail with reference to specific embodiments:

[0017] like Figures 1 to 4 The copper large-diameter rotating eye mold shown includes a housing 1, a rotating sleeve 2, a pressure head 3, a sprocket 5, a first ball bearing 6, a second ball bearing 7, and an eye mold 8. The cages of the first ball bearing 6 and the second ball bearing 7 are fixedly installed inside the housing 1. The rotating sleeve 2 is fixedly installed inside the rotating body of the first ball bearing 6 and the second ball bearing 7. The sprocket 5 is fixedly sleeved on the right end of the rotating sleeve 2. The left end of the rotating sleeve 2 has a receiving hole, and the outer end of the receiving hole is configured as a threaded hole structure. The eye mold 8 is installed in the receiving hole. The pressure head 3 is screwed and fixedly installed in the receiving hole and presses and fixes the eye mold 8. The pressure head 3 has a first through hole 31 communicating with the eye mold 8. The rotating sleeve 2 is provided with a second through hole 20 communicating with the eye mold 8.

[0018] When the pressure head 3 rotates synchronously with the rotating sleeve 2, the pressure head 3 and the rotating sleeve 2 are prone to relative rotation. In order to avoid the problem of immediate machine stoppage for maintenance during the production process, the pressure head 3 is provided with a notch 33 that runs through its left and right ends. The right end of the pressure head 3 is provided with a V-shaped groove structure 34. The V-shaped groove structure 34, together with the notch 33, has the characteristic of being able to be squeezed and contracted. Even if the pressure head 3 and the threaded hole of the receiving hole rotate outward within 10° relative to each other, the compressed V-shaped groove structure 34 is released, and the pressure head 3 can still press and fix the eye mold 8 tightly, avoiding the eye mold 8 from shaking or rotating with the rotating sleeve 2 due to gaps.

[0019] The outer end of the pressure head 3 has a tool hole 30, into which a wrench is inserted to facilitate the rotation of the pressure head 3.

[0020] The outer end of the first through hole 31 and both ends of the second through hole 20 are configured with wide-mouth structures 11 and 13 to facilitate the passage of copper wires.

[0021] The outer casing 1 has a first flange 11 on its right end, which facilitates the fixed installation of the outer casing 1 with the main body of the copper drawing equipment.

[0022] It also includes a head 4 with a second flange 41, the second flange 41 of the head 4 being screwed and fixedly installed with the first flange 11, the head 4 sealing the right end of the outer shell 1 to form a protective layer.

[0023] The outer casing 1 is fixedly mounted on the main body of the copper drawing equipment via its first flange 11. The sprocket 5 is connected to the drive motor via a transmission chain. The copper wire 10 passes through the second through hole 20 and the eye mold 8 for cold drawing. The copper wire 10 then passes through the first through hole 31. During the cold drawing operation, the sprocket 5 drives the rotating sleeve 2 and the eye mold 8 to rotate synchronously. The rotating eye mold 8 can reduce the resistance to the copper wire 10 and improve the efficiency of the cold drawing operation of the copper wire 10. The diameter of the second through hole 20 is 1.3-1.5 times the diameter of the eye mold 8. When changing the eye mold 8, unscrew the pressure head 3 and use a rod-shaped tool to push the eye mold 8 to the left through the second through hole 20.
