Description

Technical Field

[0001] The present application belongs to the technical field of laser cutting equipment, and specifically relates to a lightweight table structure. Background Art

[0002] Laser cutting is a kind of thermal cutting method that uses a focused high-density, high-power laser beam to irradiate the workpiece, so that the irradiated material quickly reaches the ignition point, and at the same time, the molten material is blown away by using a high-speed airflow coaxial with the beam, thereby achieving the cutting of the processed workpiece. The laser cutting machine is the most commonly used equipment for laser cutting. When cutting, a whole large workpiece is usually placed on the operating table, and the laser cutting machine is driven by the control system to cut the workpiece. The cut materials that meet the requirements are stored on the toothed blade of the table structure. The table structure is usually equipped with a blanking plate under the toothed blade, so that the residue generated during the laser cutting process falls on the blanking plate through the gap between the toothed blades, and then is guided by the blanking plate to the collection container under the table structure for collection. When the processing stops, the collection container is cleaned uniformly. However, some traditional laser cutting machines use a light table structure, which has insufficient load-bearing capacity and limited material storage capacity. In order to improve the load-bearing capacity and material storage capacity, some laser cutting machines use a large number of steel plates to make the table structure. The table structure is heavy, difficult to transport, and expensive. In addition, according to different needs, some production processes require the laser cutting machine to be equipped with a blanking function, but some production processes do not require the laser cutting machine to be equipped with a blanking function. However, the table structure of the laser cutting machine is currently equipped with a blanking plate as standard, which will cause functional waste and increase related costs for production processes that do not require a blanking function.

The toothed blade 2 is installed on the material-bearing frame 12 and is used to carry the materials after laser cutting. The base frame 11 supports the material-bearing frame 12. After the material-bearing frame 12 is subjected to the gravity of the material, it transmits the gravity to the base frame 11 to disperse the force and improve the material-bearing capacity. The base frame 11 is formed by a plurality of transverse support members 111 and a plurality of longitudinal support members 112 that cross each other and are rigidly connected. The material-bearing frame 12 is formed by a plurality of transverse load-bearing members 121 and a plurality of longitudinal load-bearing members 122 that cross each other and are rigidly connected to form a modular splicing, which helps to reduce the overall material usage of the frame body 1, reduces the overall weight, realizes lightweight design, improves production and processing efficiency, and reduces processing costs. The blanking plate 3 is used to guide the residues generated during the laser cutting process for collection. The blanking plate 3 can be detachably mounted on the base frame 11 to meet the production process with different requirements. For example, a production process that requires a blanking function can add a blanking plate 3 to the table structure, while a production process that does not require a blanking function can remove the blanking plate 3 from the table structure.

[0041] In a preferred embodiment, the base frame 11 and the material frame 12 can be constructed to have the same overall shape, so that the two correspond to each other up and down. The base frame 11 and the material frame 12 can be made of the same or different steel materials, and both can adopt a well-shaped or field-shaped structure design to improve the convenience of processing and structural strength. The transverse support member 111 and the longitudinal support member 112 are vertically crossed and formed by welding, and the transverse load-bearing member 121 and the longitudinal load-bearing member 122 are vertically crossed and welded.

It can be understood by those skilled in the art that, on the one hand, the connection through the participation of the connecting member 13 helps to improve the connection strength at the intersection of the transverse support member 111 and the longitudinal support member 112 and the connection strength at the intersection of the transverse load-bearing member 121 and the longitudinal load-bearing member 122, so that the overall strength of the frame body 1 is improved and the pressure-bearing capacity is higher. On the other hand, the transmission of force through the connecting member 13 also helps to more evenly disperse the gravity of the material on the material-bearing frame 12 to the base frame 11, thereby reducing stress concentration. Specifically, the connection member 13 may be made of U-shaped steel, I-shaped steel, round steel or the like. The connection member 13 may also be rigidly connected to the base frame 11 and the material-bearing frame 12 respectively by welding.

It can be understood by those skilled in the art that, compared with the legs 14 only connected to the base frame 11, the present application realizes the integrated connection of the legs 14, the base frame 11 and the material frame 12, which helps to improve the overall strength and rigidity of the table structure and enhance the pressure bearing performance of the entire structure. In a preferred embodiment, a plurality of legs 14 can be set on each side of the table structure, and the legs 14 may not be set at the corners of the table structure, but are arranged symmetrically in the center, which helps to improve the support stability. Specifically, the legs 14 can be made of U-shaped steel, I-beam, round steel and other structures, and the legs 14 can be rigidly connected to the base frame 11 and the material frame 12 respectively by welding.

As another preferred embodiment of this embodiment, Figure 2As shown, a reinforcing member 15 is provided at the position where the material-bearing frame 12 is connected to the support leg 14. The provision of the reinforcing member 15 helps to reduce or eliminate the stress generated at the positions where the material-bearing frame 12 and the base frame 11 are connected to the support leg 14 respectively after the toothed blade 2 places the material, avoids stress concentration, reduces the risk of deformation of the support leg 14, the base frame 11 and the material-bearing frame 12, and enhances the load-bearing performance. Specifically, the reinforcing member 15 can be provided as a steel reinforcing rib plate directly welded to the support leg 14 and the material-bearing frame 12.

[0045] As a preferred embodiment of this implementation, Figure 1 As shown, a lifting adjustment member 4 is installed at the bottom of the support leg 14, and the lifting adjustment member 4 can move up and down relative to the support leg 14 to adjust the height of the frame body 1.

Through this design, the base frame 11 located below is made of high-strength channel steel spliced ​​by rigid connection, which effectively ensures the load-bearing and structural stability, while the material-bearing frame 12 located above is made of low-weight flat steel spliced ​​by rigid connection, which effectively reduces the weight and achieves lightweight.

[0047] As a preferred implementation of the present application, Figure 1 and Figure 3 As shown, the blanking plate 3 is integrally constructed as a V-shaped structure in cross section, and the tip of the blanking plate 3 is arranged upward, so that the residues falling on the blanking plate 3 can slide toward the designated position under the guidance of the inclined surfaces on both sides of the blanking plate 3. Specifically, a plurality of blanking plates 3 can be arranged on the base frame 11, so that the blanking plates 3 fully correspond to and cover the gaps between the upper toothed blades 2, thereby achieving an effective blanking guiding effect.

[0048] Furthermore, if Figure 2 As shown, the base frame 11 is installed with a circular support tube 16 for supporting the blanking plate 3, and the V-shaped groove of the blanking plate 3 is inserted into the circular support tube 16. Specifically, the circular support tube 16 can be a steel tube, which can be welded between two adjacent transverse support members 111 or between two adjacent longitudinal support members 112 to provide reliable support for the blanking plate 3.

[0049] Furthermore, if Figure 2 As shown, the base frame 11 is provided with connecting protrusions 17 distributed on both sides of the circular support tube 16, and the two ends of the blanking plate 3 are respectively connected to the connecting protrusions 17 by fasteners to form a detachable connection.
