A hollow bed base for large-format cutting and welding equipment

Abstract

A hollow bed base of a large-format cutting and welding equipment includes an annular body and an installation cavity disposed inside the annular main body, and the hollow bed base of the large-format cutting and welding equipment further comprises at least one installation cavity disposed in the installation cavity. The split beam includes a vertical plate arranged in the installation cavity, the vertical plate is connected to the annular main body through the end limiting structure, and the two are connected to the bottom of the vertical plate at intervals Side support plates on both sides of the end, the upper end of the side support plate is connected with the vertical plate through the side limiting structure, the side support plate is arranged along the length direction of the vertical plate, and the two ends of the side support plate are connected by the end guide structure . The hollow bed base of the large-format cutting and welding equipment adopts the reduction of the heating surface of the split beam, avoids heat accumulation, and can adapt to the structural changes of the vertical plate deformation when the vertical plate surface is heated, while still making the vertical plate Maintain good connection reliability with the connection board.

Description

technical field [0001] The invention belongs to the technical field of laser cutting and welding machines, in particular to a hollow bed base of large-format cutting and welding equipment. Background technique [0002] Laser cutting is to use high power density laser light speed to focus on a set coordinate point to form a large energy cutting or welding material. Laser cutting has the advantages of fast cutting speed, high production efficiency and small heat affected zone, and has become the main cutting method of metal sheets. one. [0003] At present, when the bed of the laser equipment is subjected to laser cutting and welding operations, the bed is prone to structural deformation under long-term heating, which reduces the accuracy of laser cutting coordinates and causes the laser equipment to fail. For example, a Chinese patent document discloses a high-power laser cutting bed [application number: 202020827320.5], including a bed, a plurality of square grooves (1) are...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned scheme has many advantages above, there are at least the following technical problems in the above-mentioned scheme: the bed, that is, the ring frame, and the beam column with built-in separation are connected by integral casting or welding, but under long-term use, the beam column with built-in separation It will still be affected by the laser energy. After being heated, the energy will accumulate and deform and cannot be replaced. The continuous expansion of the deformation will cause the ring frame of the outer ring to be squeezed by force, which will eventually lead to the failure of the cutting and welding equipment.
