Description

Technical Field

[0001] This application relates to the technical field of gas shielded welding wire production equipment, specifically a wire drawing and threading device for gas shielded welding wire production. Background Technology

[0002] The production steps of ultrafine gas-shielded welding wire are generally as follows: 1. Material selection: Select metal or alloy materials suitable for the welding task as the base material for the welding wire. These materials typically have a low melting point, good fluidity, and weldability. 2. Material treatment: Pre-treat the selected metal or alloy materials, including cleaning, impurity removal, and purification, to ensure the quality and purity of the final welding wire. 3. Material melting: Heat the pre-treated material to its melting point, transforming it into a molten state. This can be achieved through various methods, such as resistance heating and induction heating. 4. Rolling and drawing: Gradually reduce the cross-sectional area and diameter of the molten metal through rolling and drawing methods to form ultrafine welding wire. This process needs to be carried out in high-precision equipment, with strict control of temperature and drawing speed to ensure the size and performance of the welding wire. 5. Reeling and packaging: Pack the produced ultrafine gas-shielded welding wire into appropriate reels or packaging containers for transportation and storage. During packaging, ensure that the welding wire is not damaged or contaminated.

[0039] Furthermore, the mold threading ring 7 is mounted on the upper surface of the L-shaped base 10 via the positioning base 6.

[0040] Specifically, the die threading ring 7 can be replaced according to specific needs.

A driven pressure roller 24 and an active pressure roller 25 are provided between the upper outer surfaces of the two hollow housings 21.

A stepper motor 26 is provided inside the hollow housing 21. The output shaft of the stepper motor 26 is connected to the active gear 22.

[0042] Specifically, stepper motor 26 drives the driven pressure roller 24 and the driving pressure roller 25 to rotate relative to each other through a gear transmission system, which can push the welding wire forward.

[0043] Furthermore, the vertical guide device 3 includes a mounting bracket 31.

The telescopic ends of the pneumatic telescopic rods 32 are connected to a roller positioning frame 33. A stepper motor 34 is provided on the outer side of the roller positioning frame 33. A vertical pressure roller 35 is rotatably connected to the inner side of the roller positioning frame 33. The end of the vertical pressure roller 35 is connected to the output shaft of the stepper motor 34.

[0044] Specifically, when the welding wire is detected to have broken, the pneumatic telescopic rod 32 quickly extends to engage the two vertical pressure rollers 35 together, thereby positioning the welding wire.

[0045] Furthermore, the active guide wheel 4, the lead wheel 8, the low-voltage AC power supply, and the welding wire form a test circuit, and a power failure sensor is installed on the test circuit.

[0046] Specifically, the test current is used to monitor the welding wire path.

[0047] Furthermore, the welding wire connects the active guide wheel 4 and the lead wheel 8 to the low-voltage AC power supply. The welding wire passes through the current transformer 5, but does not contact the current transformer 5.

[0048] Specifically, when the current transformer 5 fails to detect the induced current, the welding wire breaks.

[0049] Furthermore, the current transformer 5 includes a U-shaped frame 51, an electrically controlled telescopic rod 52 is provided at the opening of the U-shaped frame 51, a closed conductor is provided at the telescopic end of the electrically controlled telescopic rod 52, an inductance coil 53 is provided on the inner side of the U-shaped frame 51, and a notch is provided on the loop of the inductance coil 53 corresponding to the engagement of the closed conductor, and a current detection sensor is connected in series on the inductance coil 53.

[0050] Specifically, after the welding wire enters the U-shaped frame 51, the electrically controlled telescopic rod 52 extends and drives the closed conductor to move downward. The mutual inductance coil 53 forms a closed loop. The current detection sensor connected in series on the mutual inductance coil 53 is used to detect the current passing through the welding wire, thereby confirming whether the welding wire has broken.

[0051] Furthermore, both ends of the pneumatic telescopic rod 122 are hinged, and both ends of the pneumatic telescopic rod 123 are hinged.

[0052] Specifically, the pneumatic telescopic rod 5122 and pneumatic telescopic rod 6123 can drive the hydraulic clamp to perform pitching motion through extension and retraction.

[0053] Furthermore, the grinding mechanism 14 includes a pneumatic telescopic rod 141, a collection groove 148 and a pneumatic telescopic rod 142 installed at the telescopic end of the pneumatic telescopic rod 141, a protective cover 144 installed at the telescopic end of the pneumatic telescopic rod 142, a linear motor 143 installed at the upper end of the inner side of the protective cover 144, a linear motor 145 installed on the slide of the linear motor 143, a pneumatic telescopic rod 146 installed on the slide of the linear motor 145, and an electrically controlled grinding wheel 147 installed at the telescopic end of the pneumatic telescopic rod 146.

[0054] Specifically, when it is necessary to sharpen the end of the welding wire, the welding wire is first passed through the collection groove 148, and two hydraulic clamps 126 tighten the welding wire. Then, the electrically controlled grinding wheel 147 works, and the synchronous linear motors 145 and 143 drive the electrically controlled grinding wheel 147 to move back and forth and left and right, thereby sharpening the tip of the welding wire into a needle shape.

[0055] Furthermore, a waste collection device 15 is provided at the corner of the upper surface of the L-shaped base 10. The top of the waste collection device 15 is open. The waste collection device 15 includes a collection box 152. A linear motor 153 is symmetrically arranged on the inner side of the collection box 152. A pneumatic telescopic rod 154 is provided on the slide of the linear motor 153. A claw 155 is installed at the telescopic end of the pneumatic telescopic rod 154. An electrically controlled fixed roller 151 is installed in the middle of the inner side of the collection box 152. An electrically controlled telescopic rod 156 is provided on the inner side of the collection box 152 near the electrically controlled fixed roller 151. An electrically controlled moving roller 157 is installed at the telescopic end of the electrically controlled telescopic rod 156. The electrically controlled moving roller 157 is engaged and correspondingly arranged with the electrically controlled fixed roller 151.

[0056] Specifically, when the welding wire breaks, the hydraulic clamp 126 pulls the broken welding wire into the collection box 152. Then, the puller 155 pulls the welding wire wrapped around the hydraulic clamp 126. The electrically controlled moving roller 157 and electrically controlled fixed roller 151 bite the welding wire between them. Then, the electrically controlled moving roller 157 and electrically controlled fixed roller 151 work to pull the welding wire into the collection box 152.

[0057] In use: the coarse welding wire that needs to be drawn passes through the horizontal active pull roller mechanism 2 and the vertical guide device 3 in sequence. The welding wire that passes through the vertical guide device 3 is wound around the outer side of the active rotating roller 1 in sequence, then passes around the active guide wheel 4 and passes through the die wire threading ring 7. Finally, it is wound up by the take-up roller 9 after being guided by the lead wheel 8.

[0058] During the wire drawing process, the welding wire passes through the mutual inductance coil 53. The current detection sensor connected in series on the mutual inductance coil 53 is used to detect the current passing through the welding wire, thereby confirming whether the welding wire has broken.

[0059] If the welding wire breaks, the pneumatic telescopic rod 32 quickly extends and engages the two vertical pressure rollers 35 together, thereby positioning the welding wire. At this time, the hydraulic clamps 126 quickly move to the vertical pressure rollers 35. One of the hydraulic clamps 126 cuts the welding wire from the vertical pressure rollers 35, and the other hydraulic clamp 126 pulls the broken waste wire toward the collection box 152.

[0060] The hydraulic clamp 126 pulls the broken waste wire into the collection box 152. Then, the puller 155 pulls the welding wire wrapped around the hydraulic clamp 126. The electrically controlled moving roller 157 and electrically controlled fixed roller 151 bite the welding wire between them. Then, the electrically controlled moving roller 157 and electrically controlled fixed roller 151 work to pull the welding wire into the interior of the collection box 152.

[0061] After the waste wire is cleaned up, the end of the welding wire needs to be sharpened. First, the hydraulic clamp 126 pulls the welding wire through the collection groove 148. The two hydraulic clamps 126 are located at both ends of the collection groove 148 to tighten the welding wire. Then, the electric control grinding wheel 147 works, and the synchronous linear motors 145 and 143 drive the electric control grinding wheel 147 to move back and forth and left and right, thereby grinding the tip of the welding wire into a needle shape. Then, one of the hydraulic clamps 126 sends the small broken wire segments generated during the sharpening process into the collection box 152.

[0062] Another hydraulic clamp 126 pulls the welding wire to wind around the outer side of the active rotating roller 1 in sequence, then passes around the active guide wheel 4 and through the die threading ring 7. Finally, guided by the lead wheel 8, it is wound up by the take-up roller 9. When passing through the die threading ring 7, one hydraulic clamp 126 is responsible for threading the wire, and the other hydraulic clamp 126 is responsible for pulling the welding wire through the die threading ring 7 at the other end. The final winding connection of the take-up roller 9 can be done manually.

[0063] It is worth noting that in this application, the input ends of stepper motor 26, pneumatic telescopic rod 32, stepper motor 34, electrically controlled telescopic rod 52, linear motor 11, mechanical wire-pulling arm 12, grinding mechanism 14 and waste collection device 15 are all electrically connected to the output end of an external power supply through an external controller.
