Description
Technical Field
[0001] This utility model relates to an irregularly shaped laser cutting and welding machine. Background Technology
[0002] Currently, steel coil cutting and welding are typically performed using separate equipment. This involves first cutting the edges of the steel coil using a cutting device, and then welding the cut coils together using a welding device. Traditional equipment mainly consists of a fixed pressing device, a cutting device, and a welding device. The workflow is as follows: the steel coil is fed into the pressing device through the feeding channel and fixed; the cutting device cuts the coil along a straight or simple curved path; and then the welding device welds the cut coils together.
[0003] However, the above methods have the following problems: traditional straight-line cutting methods cannot optimize the edge shape of steel coils according to actual stamping requirements, resulting in low material utilization and high scrap rate; since cutting and welding are carried out in separate steps, the equipment occupies a large area and the process connection efficiency is low, which affects the production cycle. In addition, misalignment is prone to occur when steel coils are joined during welding, which affects the weld quality and requires frequent manual adjustments, increasing the complexity of operation.
[0004] Therefore, there is an urgent need for a device that can integrate irregular shape cutting and welding, and an irregular shape laser cutting and welding machine and cutting and welding method that can improve material utilization and reduce waste. Utility Model Content

[0021] In this embodiment, the welding torch can be connected to the controller via a dual-core optical fiber. By switching the optical fiber, the cutting and welding functions of the welding torch can be switched. Such a laser device that can both cut and weld is available on the market and will not be described in detail here. Choosing such a laser device that can both cut and weld significantly improves the versatility and efficiency of the equipment and avoids the downtime caused by the need to change different tools in traditional equipment.
[0022] like Figure 1 , 2 As shown, the pressing device includes a left pressing slide 3 that can move left and right on the left side of the frame 1 and a right pressing slide 4 that can move left and right on the right side of the frame 1.

The right pressing slide 4 includes a right pressing fixture 41 with an irregular shape at the edge. The right pressing fixture 41 has a second feeding channel for steel coils to enter in the middle. The left pressing fixture 31 and the right pressing fixture 41 are aligned to form a gap channel. The irregular shapes of the edges of the left pressing fixture 31 and the right pressing fixture 41 match. By using movable left and right pressure carriages and matching irregularly shaped pressure fixtures, the integrated processing of irregular cutting and welding of steel coils is realized. The cutting and welding of steel strip ends are completed on the same equipment, eliminating the material transfer steps between the cutting machine and the welding machine in the traditional process, shortening the production cycle. At the same time, the use of irregular cutting is suitable for stamping scenarios with special requirements, which can reduce the generation of waste and effectively reduce material waste.
[0023] like Figure 2 As shown, the left pressure carriage 3 also includes a left sliding plate (not shown) that is moved along the left and right direction on the frame 1 via a slide rail, a left pressure plate 32 that is set directly above the left sliding plate for pressing the left pressure fixture 31, and a width limiting plate 33 that is slidably set along the length of the left pressure plate 32.

[0025] When the pressing device is in the working position, the left pressing fixture 31 and the right pressing fixture 41 are aligned and flush, the first feeding channel and the second feeding channel are aligned and flush, and a gap channel is formed between the left pressing fixture 31 and the right pressing fixture 41. The welding torch is set directly above the gap channel and can move back and forth along the length of the gap channel.
[0026] When the pressing device is in the working position, it has a cutting state and a welding state. When the pressing device is in the cutting state, the left pressing slide 3 and the right pressing slide 4 are far apart, and the welding gun can cut along the irregular edge of the left pressing fixture 31 or the right pressing fixture 41. When the pressing device is in the welding state, the left pressing slide 3 and the right pressing slide 4 are close together, the left pressing fixture 31 and the right pressing fixture 41 are aligned, the first feeding channel and the second feeding channel are aligned and connected, a weld bead is formed between the left pressing fixture 31 and the right pressing fixture 41, and the welding gun is set directly above the weld bead and can move along the length of the weld bead to perform welding.
[0027] like Figure 1 As shown, a first linear module 44 with the same length direction as the right pressure plate 42 is also provided on the right pressure plate 42.

The modular linear module design optimizes the movement path of the welding torch and reduces the space occupied by the equipment.
[0028] The welding torch 2 is equipped with a laser positioner. The laser positioner emits in a direction parallel to the working direction of the welding torch 2, and is used to calibrate the relative position of the welding torch 2 with the edges of the left pressure fixture 31 and the right pressure fixture 41 in real time.
[0029] Working principle: The cutting and welding method specifically includes the following steps: Step 1, move the left pressure carriage 3 and the right pressure carriage 4 away from each other; Step 2, introduce one end of the first steel coil into the first feed channel of the left pressure fixture 31 from the outside until one end of the first steel coil extends out of the irregular edge of the left pressure fixture 31, and after clamping, drive the welding torch 2 to move along the irregular edge of the left pressure fixture 31 to perform the first cut; Step 3, introduce one end of the second steel coil into the second feed channel of the right pressure fixture 41 from the outside.
