Description

Technical Field

[0001] The utility model relates to the field of automatic welding production lines for spools, and more specifically, to an automatic welding production line for spools. Background Art

[0002] A spool is a tool for winding metal wires or steel wire ropes. Its shape is similar to the Chinese character "工" and is mainly made of steel or plastic. It has the characteristics of high strength, good balance performance, acid and alkali corrosion resistance, etc. Spools are widely used in multiple processes in the wire and cable and steel wire welding industries, such as wire drawing, copper plating, annealing, bunching, stranding, armoring, cabling, etc. In recent years, spools are mainly used for pay-off and take-up of hose steel wires, spring steel wires, cutting steel wires, etc. The material and specification of the spool vary according to the material and specification of the wound wire rope. Spools for winding steel wires generally use a steel plate structure, while fine steel wires and non-ferrous metal wires can use wooden spools.

[0003] A laser welding machine is a thermal processing technology that uses a laser beam as a heat source. Compared with electron beam, plasma beam and general mechanical processing, it has many advantages. The laser focus spot of the laser beam is small, and the power density is high, which can weld some alloy materials with high melting points and high strengths. Moreover, laser welding is a non-contact processing. A spool is a tool for winding metal wires or steel wire ropes. For the special shape of the spool, it is composed of a middle cylinder and two end discs.

[0004] In the processing of metal spools, it is necessary to weld one end disc of one spool to one end disc of another spool through a laser welding machine. However, in the process of clamping two spools by the existing laser welding machine equipment, it is necessary to fix the two spools separately, and it is very cumbersome to fix the spools with the fixture. It only applies to the fixation of the column diameter of one type of spool. Then, the two spools are butted. The manual operation cannot ensure the accuracy of the alignment of the discs of the two spools, thus affecting the welding efficiency and quality of the subsequent laser welding machine.

[0005] In the prior art, such as the invention disclosed in authorization announcement number CN115673551A, a laser welding machine for welding H-beams with stable alignment and clamping is provided. This machine includes a laser welding machine and a processing platform for welding H-beams. The laser welding machine is fixedly installed on one side of the processing platform. A laser welding head is provided on the inner top of the laser welding machine, and a driving and moving mechanism is provided on the laser welding head. A fixed seat is provided on the processing platform, and a first sliding groove is provided on the fixed seat. A first transmission screw is provided on the fixed seat within the first sliding groove. The first transmission screw has a double-screw structure with opposite thread directions. This invention, through the threaded engagement between the first transmission screw and two movable sliding seats, plus the clamping assembly and support seat forming a vertical and horizontal clamping of the H-beam, facilitates rapid clamping, fixing, and alignment of the two H-beams. It is also suitable for clamping and fixing H-beam cylinders of various diameters, ensuring the accuracy of the disc alignment of the two H-beams, thereby improving the welding efficiency and quality of the subsequent laser welding machine.

[0006] In the aforementioned patent, the cylindrical body is clamped in the middle of the disc, making it difficult to position. The cylindrical body cannot be adjusted to match the disc, making it inconvenient to use. Furthermore, the I-beam wheel, after being welded and formed, is difficult to transport. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic welding production line for I-beam wheels.

In addition, an adjustable support block structure is set to support the middle cylindrical structure, which can be moved up and down to adjust the alignment, making it convenient to use.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An automatic welding production line for I-beam reels includes a welding stand with an angled guide plate on its inner surface. A first motor is fixedly connected to one outer surface of the welding stand. The outer surface of the drive shaft of the first motor is connected to the inner surface of the welding stand via a bearing. The outer surface of the drive shaft is threaded, and a movable seat is threaded to the outer surface of the drive shaft. A laser welding machine is mounted on the outer surface of the movable seat, with a welding head at its lower end.

The adjustable support block structure can support the middle cylindrical structure and can be moved up and down for adjustment and alignment, making it easy to use.

[0010] Furthermore, a positioning strip is fixedly connected to the upper inner surface of the welding seat, and a square through-hole is provided on the upper surface of the movable seat, with the inner surface of the square through-hole of the movable seat fitting onto the outer surface of the movable seat.

[0011] Furthermore, the surface of the support block is provided with a triangular positioning groove, and the inner surface of the triangular positioning groove is smoothly polished.
