Description

Technical Field

[0001] The present invention belongs to the technical field of welding wires, and in particular relates to a large-capacity intelligent welding wire storage device and a welding wire production system. Background Art

[0002] Welding wire materials primarily include carbon steel, stainless steel, aluminum alloy, copper alloy, and nickel alloy. Each of these wires is suitable for different metal materials and possesses unique properties, such as strength and corrosion resistance. Furthermore, welding wire can be categorized by welding method and shape, such as gas metal arc welding (GMAW), tungsten inert gas (TIG), and flux-cored wire.

[0003] Current welding wire production systems primarily consist of a hot-melt extruder, a drawing unit, a wire storage unit, and a winding unit. The hot-melt extruder, the initial stage of the production line, melts the raw metal at high temperatures and extrudes it through a die to form a thick initial billet wire. The drawing unit is responsible for dimensional finishing, employing a multi-stage progressive process to convert the thick wire into a thinner wire of corresponding specifications. The wire storage unit serves as the central control center for production rhythm, adapting to speed differences between preceding and following processes. The winding unit, the final packaging step, is used to reel the welding wire.

[0004] Existing welding wire production systems have shortcomings. First, their wire storage device design is not rational, unable to achieve large-capacity intelligent wire storage, and lacks anti-pull wiring function, resulting in the wire being easily broken due to pulling after being fed to the winding device. Second, their drawing device design is not rational, and wire breakage is prone to occur during the drawing process. Third, their winding device design is not rational, and it cannot achieve automatic coil changing, affecting the overall production efficiency of welding wire. Therefore, it is necessary to optimize and improve the existing welding wire production system. Summary of the Invention

[0056] The specific application of this embodiment is as follows: Regarding the wire storage part, the present large-capacity intelligent wire storage device 1 is mainly composed of a vertical frame 101, a horizontal frame 102, an active wire storage unit, a passive wire storage unit, an end-aligning wheel 120, a traction unit, a wire pressing unit, and a wiring unit. Each unit cooperates with each other. When the winding device needs to change the reel, the wire pressing unit presses the welding wire tightly. Since the welding wire at the rear is paused, the counterweight buffer wheel 109 of the front passive wire storage unit will descend, realizing passive wire storage. When the counterweight buffer wheel 109 moves down to be detected by the lower photoelectric sensor, the lower photoelectric sensor sends a signal to the controller, which controls the vertical linear guide pair of the active wire storage unit to move, so that the second wire pulley 104 of the active wire storage unit moves downward relative to the first wire pulley 103, realizing active wire storage. When the counterweight buffer wheel 109 of the passive wire storage unit moves up to be detected by the higher photoelectric sensor, the higher photoelectric sensor sends a signal to the controller, which controls the vertical linear guide pair of the active wire storage unit to stop moving. When the reel change is completed, the wire pressing unit releases the pressure on the welding wire, and the winding speed is controlled to be higher than the wire output speed of the large-capacity intelligent wire storage device 1. When the counterweight buffer wheel 109 of the passive wire storage unit moves up to be detected by the high-position photoelectric sensor, the high-position photoelectric sensor sends a signal to the controller, and the controller controls the vertical linear guide pair of the active wire storage unit to move, so that the second wire wheel 104 of the active wire storage unit moves up relative to the first wire wheel 103, thereby realizing the active release of the buffered welding wire. By monitoring the position of the wire storage slider 105 in the vertical linear guide pair to determine when the welding wire release is about to end, the winding speed is controlled to be consistent with the wire output speed of the large-capacity intelligent wire storage device 1. At this time, the automatic wire storage function of the passive wire storage unit can be used to eliminate the influence of speed difference fluctuations during the non-reel change period.

[0057] Regarding the wiring part, the wiring unit is provided with a front wire component 117, an intermediate wire component 118 and a rear wire component 119. The front wire component 117 is used to introduce the welding wire, the swing of the intermediate wire component 118 is used to adapt to the change of the winding position of the subsequent winding device, and the rear wire component 119 is used to lead out the welding wire. Through this over-guiding wiring method, it is possible to avoid the occurrence of breakage of the welding wire due to excessive force during the winding process. Example 2

[0058] like Figure 3As shown, this embodiment provides a welding wire production system, which includes a controller 5, a hot melt extrusion device 3, a drawing device 4, a winding device 2 and the large-capacity intelligent wire storage device 1 for welding wire in Example 1.

[0059] like Figure 4-Figure 6 As shown, the winding device 2 includes a base plate 201, a servo motor 202, a rotating plate 203 and an internally supported winding mechanism 204.

[0061] The working principle of the winding device 2 is as follows: the internal support winding mechanism 204 is used to clamp the winding bobbin 6, and the servo motor 202 drives the rotation plate 203 to rotate, so that the winding bobbin 6 clamped by the internal support winding mechanism 204 enters the winding station in sequence. Then, the internal support winding mechanism 204 in the winding station activates the winding motor 2048, which drives the driven gear ring 2047 and the sliding sleeve 2046 to rotate via the drive gear 2049. The square column 2044 and the internal support jaws 2045 also rotate accordingly, completing the winding operation. When the winding is completed, the internal support jaws 2045 release the internal support, and the horizontal push rod 2042 drives the square column 2044 and the internal support jaws 2045 to retract, and the winding bobbin 6 automatically falls into the material area below (because the baffle 602 protects the welding wire from damage).

[0066] The working principle of the drawing device 4 is as follows: two drawing pulleys 404 are used to draw the thick wire extruded by the hot melt extrusion device 3 so that it reaches the set wire diameter. The drawing pulleys 404 are sprayed with oil using a debris flushing spray pipe 409, and the spraying direction is tangential. In this way, the welding wire in the variable diameter spiral drawing groove 413 can be lubricated by the oil. At the same time, the flow of the oil can flush away the debris generated by the drawing and take away some of the heat, thereby achieving continuous cooling of the drawing pulleys 404 and avoiding wire breakage caused by high temperature. The debris washed away is intercepted and collected by the debris filtering component 405, and the oil pump 406 and the return oil pipe 407 are used to return the oil to the cooling box 408. After cooling in the cooling box 408, the oil is sent to the debris flushing spray pipe 409 again.

[0067] The specific application of this embodiment is: the welding wire production system is mainly composed of a controller 5, a hot melt extrusion device 3, a drawing device 4, a winding device 2 and a large-capacity intelligent wire storage device 1 for welding wire. The various devices work together. The drawing device 4 can be used to draw the thick wire extruded by the hot melt extrusion device 3 into a thin wire. During the drawing process, the drawing tower can be lubricated, cooled and debris cleaned, thereby effectively avoiding wire breakage; the winding device 2 can be used to continuously wind and reel the welding wire, and automatic reel change can be achieved; when reel change is required, the large-capacity intelligent wire storage device 1 for welding wire can be used to store and release the wire, avoiding downtime and ensuring the production efficiency of the welding wire.
