Description

Technical Field

[0001] This invention belongs to the technical field of welding material production equipment, and in particular relates to a copper-plated welding wire drawing anti-extrusion device. Background Technology

[0002] The production of welding wire utilizes a straight-feed wire drawing machine. The welding wire is forced into the drum from the root, while existing wires on the drum are pushed upwards and aligned. This operation causes compression and friction between the wires and between the wires and the drum. Especially during the sizing and polishing of copper-plated welding wire after plating, the compression and friction between the wires and between the wires and the drum as the drum rotates can easily damage the relatively soft copper plating layer, increasing the wire feeding resistance and affecting welding stability. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a copper-plated solder wire drawing anti-extrusion device.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A copper-plated welding wire drawing anti-extrusion device includes a wire-separating wheel arranged corresponding to the wire drawing drum. The angle between the axis of the wire-separating wheel and the vertical direction is greater than the angle between the axis of the wire drawing drum and the vertical direction. The wire-separating wheel is installed on the upper end of the wire-separating wheel shaft, and the lower end of the wire-separating wheel shaft is hinged to the inner cavity of the base via a hinge shaft. A bearing is provided between the wire-separating wheel and the wire-separating wheel shaft. The base is provided with an angle adjustment component for adjusting the tilt angle of the wire-separating wheel shaft, and a fixing bolt for fixing the wire-separating wheel shaft. The angle adjustment component includes limiting bolts respectively provided on both sides of the wire-separating wheel shaft. The axial direction of the fixing bolt is parallel to the axial direction of the hinge shaft, and the axial direction of the limiting bolt is perpendicular to the axial direction of the hinge shaft.

[0006] Furthermore, the two limiting bolts are arranged symmetrically with respect to the dividing wheel axis.

[0007] Furthermore, the bearing component is a deep groove ball bearing.

[0008] Furthermore, a bearing component is provided at each end of the dividing wheel, and a bearing positioning sleeve is provided between the two bearing components.

[0009] Furthermore, the bearing positioning sleeve is fitted onto the dividing wheel shaft.

[0010] Furthermore, a pressure cap is fitted onto one end of the dividing wheel that extends upward from the dividing wheel shaft, and the pressure cap is locked by a pressure cap bolt connected to the end of the dividing wheel shaft.

[0011] Furthermore, the limiting bolts are screwed onto the two side plates of the base, with one end of the bolt extending into the inner cavity of the base.

[0012] Furthermore, the outer diameter of the dividing wheel is smaller than the outer diameter of the wire drawing drum.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a reasonable structural design. During production, after the welding wire passes around the wire drawing drum, it first passes around the dividing wheel of the anti-extrusion device, and then winds around the wire drawing drum again. It is wound multiple times in the above sequence. By adjusting the tilt angle of the dividing wheel on the anti-extrusion device, the welding wire is automatically separated into uniform intervals and wound on the wire drawing drum. This effectively avoids the squeezing and friction caused by close contact between the welding wires on the drum, eliminates the scratches caused by squeezing and friction, and improves product quality.

[0024] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A copper-plated solder wire drawing anti-extrusion device, such as Figures 1 to 5 As shown, it includes a wire-separating wheel 7 arranged corresponding to the wire drawing drum. The angle between the axis of the wire-separating wheel and the vertical direction is greater than the angle between the axis of the wire drawing drum and the vertical direction. The wire-separating wheel is installed on the upper end of the wire-separating wheel shaft 3. The lower end of the wire-separating wheel shaft is hinged to the inner cavity of the base 1 through a hinge shaft 2. A bearing 6 is provided between the wire-separating wheel and the wire-separating wheel shaft.

[0026] The base is equipped with an angle adjustment assembly 4 for adjusting the tilt angle of the dividing wheel shaft, and a fixing bolt 5 for fixing the dividing wheel shaft. The angle adjustment assembly includes limiting bolts on both sides of the dividing wheel shaft; the axial direction of the fixing bolt is parallel to the axial direction of the hinge shaft, and the axial direction of the limiting bolt is perpendicular to the axial direction of the hinge shaft. In an optional embodiment, an arc-shaped groove 11 is provided on the front or rear panel of the base. The fixing bolt is installed in the arc-shaped groove, and the fixing bolt slides in contact with the arc-shaped groove. After the fixing bolt is loosened, the angle of the dividing wheel shaft can be adjusted (so that the angle between the dividing wheel and the machine is appropriate). When the angle of the dividing wheel shaft is adjusted, the fixing bolt moves with the dividing wheel shaft and slides in contact with the arc-shaped groove. After the dividing wheel shaft rotates to the appropriate position along the hinge shaft, the fixing bolt is tightened to re-fix the dividing wheel shaft.

[0027] The limiting bolts are used to adjust the rotation angle and position the dividing wheel shaft. Preferably, the two limiting bolts are arranged symmetrically with respect to the dividing wheel shaft. A bearing is provided at each end of the dividing wheel, and the bearing is a deep groove ball bearing to ensure the positioning and stable rotation of the dividing wheel on the dividing wheel shaft.

[0028] Meanwhile, a bearing positioning sleeve 8 is provided between the two bearing components, and the bearing positioning sleeve is fitted onto the wire dividing wheel shaft. A pressure cap 9 is fitted onto one end of the wire dividing wheel shaft extending upwards, and the pressure cap is locked by a pressure cap bolt 10 connected to the end of the wire dividing wheel shaft. The limiting bolts are screwed onto the two side plates of the base, with one end of its screw extending into the inner cavity of the base. The outer diameter of the wire dividing wheel is smaller than the outer diameter of the wire drawing drum.

[0029] Working principle:

[0030] First, adjust the dividing wheel 7 to form a suitable tilt angle with the wire drawing drum. Main view: a1 is the inherent angle between the drum and the machine, a2 is the adjustable angle between the dividing wheel 7 and the machine. During use, adjust a2 to be greater than a1 and fix it.

[0031] Then, the welding wire is wound along the wire drawing drum and passed through the wire separating wheel 7 with a certain inclination angle, and then wound back onto the wire drawing drum to complete one cycle.

[0032] Finally, repeat the winding process multiple times based on the height required for the welding wire to leave the drum.

[0033] Because the tilt angle α1 of the wire drawing drum is smaller than the tilt angle α2 of the dividing wheel 7, their axes are not parallel. An angle difference α2-α1 is formed between the section of welding wire passing through the wire drawing drum to the dividing wheel 7 and the section passing through the dividing wheel 7 to the wire drawing drum. Due to this angle difference and the fixed distance between the drum and the anti-extrusion device, a uniform gap is generated between the welding wire and the drawing drum and the dividing wheel 7. The size of this gap can be adjusted by adjusting the angle difference α2-α1. Therefore, in continuous drawing operations, when the welding wire passes through the wire drawing drum, the gap between the upper and lower layers of welding wire effectively avoids mutual extrusion and friction, significantly reducing surface scratches on the welding wire.

[0034] This invention features a rational structural design. During production, after the welding wire passes over the wire drawing drum, it first passes over the dividing wheel of the anti-extrusion device, and then winds back onto the wire drawing drum. This process is repeated multiple times in the above sequence. By adjusting the tilt angle of the dividing wheel on the anti-extrusion device, the welding wire is automatically separated into uniform intervals and wound onto the wire drawing drum. This significantly reduces scratches and marks caused by extrusion and friction, resulting in a marked improvement in the surface quality of the copper film on the finished welding wire. The welding stability of the welding wire is also significantly improved. Furthermore, this invention is also applicable to the drawing of non-ferrous metal wires, and has a significant effect on improving the surface quality of non-ferrous metal wires.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
