Description

Technical Field

[0001] The invention belongs to the technical field of wire billet welding, in particular to a wire billet butt welding method. Background Art

[0002] In the production process of pipe fittings or wire billets, in order to obtain a continuous wire billet of sufficient length, it is often necessary to butt-weld the ends of different wire billets. Currently, the butt welding process in the production process is generally carried out by manually welding the ends of two reels of wire billets, and then manually flipping the two different reels of wire billets into one reel before the next welding. Since the wire billet coils are generally heavy and easily loosened, the manual flipping process is not only labor-intensive but also prone to safety accidents.

[0003] It can be seen that the traditional wire billet butt welding method not only has low production efficiency and high labor intensity, but also has safety risks. Therefore, it is necessary to propose a new wire billet butt welding method. Summary of the Invention

[0004] In order to solve the problems in the prior art of wire blank butt welding that are labor-intensive, pose safety risks, and have low work efficiency, the present invention provides a wire blank butt welding method, which can automatically rotate the coil to be welded by rotating the material tray, and automatically rotate the welded wire blank coil by the welding machine, so that the loose wire blank at the welding position between the two coils is tightened to form an integral material tray, which has a high degree of automation and improves work efficiency.

[0005] The present invention provides a wire billet butt welding method, and the technical solution thereof for solving the technical problem comprises the following steps:

[0006] S1: Place multiple wire coils (1#-n#) evenly distributed on the rotating material tray in advance;

[0007] S2: The welding feeder rotates to the receiving station and feeds the 1# wire billet coil onto the receiving rod of the welding feeder;

[0008] S3: The butt welding machine rotates the 1# wire billet coil to the butt welding station and welds the tail of the 1# wire billet coil to the head of the 2# wire billet coil on the rotating material tray;

[0009] S4: The welding machine is rotated to the material receiving station again, and the rotary tray is rotated 360 / n degrees to rotate the 2# wire billet coil to the material receiving station;

[0010] S5; After the rotating receiving rod tightens the wire between the 1# wire billet coil and the 2# wire billet coil, the rotating material tray feeds the 2# wire billet coil into the receiving rod of the welding machine;

[0011] S6: Repeat the above steps S3-S5 to complete the butt welding operation of the 3#-n# wire coils in sequence;

[0012] S7: The butt welding feeder rotates to the unloading station to unload the 1#-n# wire coils that have been butt-welded as a whole.

[0013] By adopting the butt welding method of the present invention, semi-automatic butt welding operation is realized. Automatic loading, automatic turning and automatic unloading can be realized by rotating the material tray and the butt welding material machine, which reduces manual labor, reduces safety risks, improves production efficiency, and realizes continuous welding of heavy coils.

[0014] Preferably, a pusher mechanism is provided at the center of the rotating feed tray. The pusher mechanism comprises a pusher rod and a pusher drive component. One end of the pusher rod faces the material receiving station, and the pusher drive component drives the pusher rod to intermittently extend and retract. The pusher mechanism automatically delivers the wire coils on the rotating feed tray to the butt welding feeder, reducing manual labor and ensuring continuous butt welding.

[0015] Preferably, in step S3, the head and tail of the wire stock coils are removed before butt welding. Because the ends of the wire stock coils generally have an oxide layer that affects the welding quality, the ends of the two wire stock coils need to be removed before butt welding to ensure the reliability of the welding connection.

[0016] Preferably, the welding station and the material unloading station are distributed on both sides of the material receiving station. Such an arrangement can reduce the transfer of materials between different stations during the entire operation process and improve production efficiency.

[0017] Preferably, the number n of the wire stock coils is 4, 5 or 6. The number of wire stock coils can be set to different numbers according to production needs, making production more flexible.

[0018] Preferably, the splicing rod comprises two spaced-apart, parallel rods that are independent of each other and capable of synchronously rotating about their own axes. The splicing rod is inserted into the inner hole of the wire stock coil. During turnover, friction with the inner wall of the wire stock coil drives the wire stock to rotate, achieving automatic turnover of the wire stock coil. This automatically tightens any loose wire stock between the two reels during welding, ensuring the integrity of the two butt-welded wire stock coils.

[0019] Preferably, the rotation of the two rods is driven by the same driving component, which is convenient for arrangement and can better ensure the synchronization of the rotation of the two receiving rods and ensure the stability of the line blank coil during the turning process.

[0020] Preferably, the rotating material tray is provided with a plurality of mounting portions for placing the wire stock coils, each of which is provided with two mounting rods that are parallel to each other and equidistant from the two rod bodies. When the receiving rods rotate to the receiving station, the receiving rods and the mounting rods are aligned, which makes it easier for the pushing mechanism to push the wire stock coils on the rotating material tray along the mounting rods and the receiving rods to the welding feeder.

[0021] In summary, the technical solution of the present invention has at least the following beneficial effects:

[0022] 1. Through the design of the rotating material tray, multiple coils of wire billets can be placed on the tray in advance. Through the rotation of the rotating material tray, the material can be fed quickly and automatically during the welding process, which improves the loading efficiency;

[0023] 2. After the two coils of wire are welded, the wire coils can be automatically flipped by the material receiving rod on the welding machine, which reduces the labor of manual flipping, and the flipping is reliable, reducing safety risks;

[0024] 3. Improved the butt welding efficiency of wire billets. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present invention provides a wire blank butt welding method, see the attached Figure 1-7 , including the following steps:

[0036] S1: Pre-place multiple circumferentially evenly distributed wire coils 3 (1#-n#) on the rotating material tray 1; the number of wire coils 3 in the present invention can be pre-placed according to actual needs, wherein the rotating material tray 1 is provided with multiple mounting portions for placing the wire coils 3, and the mounting portions are provided with two mutually parallel mounting rods 6, such that the mounting rods 6 pass through the middle of the wire coils 3 to support the wire coils 3. See the attached Figure 1 In this embodiment, 6 wire blank coils 3 are used as an example for explanation. The 6 wire blank coils 3 are distributed circumferentially; the butt welding operation is performed in sequence;

[0037] S2: See Appendix Figure 2 , the welding feeder 2 rotates to the feeding station A, and feeds the 1# wire blank coil into the feeding rod 5 of the welding feeder 2; when the welding feeder 2 rotates to the feeding station A, the feeding rod 5 and the mounting rod 6 are in the same straight line, wherein the feeding rod 5 includes two rod bodies arranged at intervals and in parallel, and the interval of the mounting rod 6 is equal to the interval of the rod bodies, so that the two rod bodies of the feeding rod 5 are aligned with the two mounting rods 6 respectively, which facilitates the wire blank coil 3 to enter the welding feeder 2 from the rotating material tray 1.

[0038] S3: See Appendix Figure 4 ; The butt welding machine 2 rotates 90° counterclockwise with the 1# wire billet coil to the butt welding station B, and welds the tail of the 1# wire billet coil to the head of the 2# wire billet coil on the rotating material disk 1; the butt welding operation is performed manually on the welding workbench at the butt welding station B. Before the welding operation, the ends of the two wire billets 3 to be welded need to be removed first to avoid the oxide layer at the ends affecting the welding quality.

[0039] S4: See Appendix Figure 5 After the welding is completed in S3, the welding machine 2 is rotated again (90° clockwise) to the material receiving station A, and the rotary material tray 1 is rotated 360 / n degrees. It should be noted that since one end of the 1# wire billet coil and the 2# wire billet coil have been welded to each other, in order to avoid the wire billet being torn off during the position change of the welding machine 2 and the rotary material tray 1, it is necessary to ensure that the two move synchronously. In this embodiment, the welding machine 2 is rotated 90° clockwise to reach the material receiving station A. , the rotating material disc 1 rotates 60° counterclockwise so that the 2# wire billet coil reaches the material splicing station A. After both arrive at the material splicing station A, step S5 is performed; the splicing rod 5 is rotated to tighten the wire billet between the 1# wire billet coil and the 2# wire billet coil. The tightening here is to wind the loose wire billet between the 1# wire billet coil and the 2# wire billet coil after the butt welding, so that it is wound into a roll. Specifically, it is achieved by the self-rotation of the splicing rod 5. The two rods in this application are independent of each other and can rotate synchronously around their own axes. In this way, the splicing rod 5 is inserted into the inner hole of the wire billet coil 3, and the rotation of the wire billet is driven by friction with the inner wall of the wire billet coil 3, so that the wire billet coil 3 is automatically flipped, so that the loose wire billet between the two wire discs is automatically tightened into a roll during the welding process, and the integrity of the two butt-welded wire billets 3 is ensured. When the loose wire stock between the 1# wire stock coil and the 2# wire stock coil is wound and tightened, the pushing mechanism feeds the 2# wire stock coil to the receiving rod 5 of the welding feeder 2;

[0040] S6: Repeat the above steps S3-S5 to complete the butt welding operation of the 3#-6# wire stock coils 3 in sequence; finally, complete the butt welding of all the wire stock coils 3, and all the wire stock coils 3 form a whole;

[0041] S7: See Appendix Figure 7 The welding feeder 2 rotates clockwise to the blanking station C, and blanks the 1#-6# wire coils 3 that have been butt-welded as a whole.

[0042] It can be seen that the butt welding method of the present invention realizes semi-automatic butt welding operation. By rotating the material tray 1 and the butt welding material machine 2, automatic loading, automatic turning and automatic unloading can be realized, which reduces manual labor, reduces safety risks and improves production efficiency.

[0043] To transfer the wire stock coil 3 from the rotating tray 1 to the butt welding feeder 2, the present invention provides a pusher mechanism at the center of the rotating tray 1. This pusher mechanism comprises a pusher rod 4 and a pusher drive component. One end of the pusher rod 4 faces the material receiving station A, and the pusher drive component drives the pusher rod 4 in intermittent telescopic motion. The pusher mechanism automatically transfers the wire stock coil 3 from the rotating tray 1 to the butt welding feeder 2, reducing manual labor and ensuring continuous butt welding.

[0044] In order to reduce the floor space occupied by the entire butt welding operation, the present invention distributes the butt welding station B and the unloading station C on both sides of the material receiving station A. This arrangement can reduce the transfer of materials between different stations during the entire operation process and improve production efficiency.

[0045] The number n of the wire stock coils 3 in the present invention is 4, 5 or 6. The number of the wire stock coils 3 can be set to different numbers according to production needs, making production more flexible.

[0046] The rotation of the two rods of the material receiving rod 5 in the present invention is driven by the same driving component. This can reduce equipment costs, facilitate layout, better ensure the synchronization of the rotation of the two material receiving rods 5, and ensure the stability of the line blank coil 3 during the turning process.

[0047] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
