With reference to fig. 1 to 3, the present invention provides a honeycomb substrate for a laser cutting machine, which is horizontally laid on a cutting platform right below a laser cutting device of the laser cutting machine.
The honeycomb bottom plate is composed of a plurality of bottom plate unit cells 10, each bottom plate unit cell 10 is formed by connecting and closing a certain amount of grid walls 20 end to end, and adjacent bottom plate unit cells 10 share one grid wall 20.
The mesh wall 20 has a first end and a second end in a vertical direction; the first end part is a horizontal end surface connected with the cutting platform; the second end portion is close to the laser cutting device and comprises a first end face 21, a second end face and a third end face 22 which are sequentially connected, wherein:
the first end face 21 and the third end face 22 are inclined, symmetrically arranged at two sides of the second end face, and respectively form included angles A and A' with the upper surface of the honeycomb baseplate.
With the further development of laser technology and the improvement of the requirements of the market on workpiece integration and integrity, the width and the length of a cutting platform of laser cutting equipment such as a laser cutting machine and a honeycomb bottom plate positioned above the cutting platform are also larger and larger, and are gradually increased from 3-4 meters to 7-8 meters, even more than 10 meters. And is limited by processing conditions and material properties, the cross-section of the material forming the honeycomb cells also widens (e.g., the thickness of cell walls 20 increases by about 1mm for every 2 meters increase in floor length). On the basis, the invention provides that the cross section of the honeycomb bottom plate grid wall is changed into a pointed cross section with a certain angle included angle from the traditional flat angle horizontal type, so that the reflection section of the laser falling from the right upper side on the bottom plate is reduced to the maximum extent, the secondary damage to the bottom surface of a processing material caused by laser reflection is reduced, the defective rate is reduced, the efficiency is increased, and the invention has obvious economic value.
In order to prevent the workpiece from being damaged by the pointed cross section, the second end part is formed by sequentially connecting a first end surface 21, a second end surface 23 and a third end surface 22, wherein the first end surface 21 and the third end surface 22 are inclined and symmetrically arranged at two sides of the second end surface 23 and form included angles A and A' with the upper surface of the honeycomb baseplate respectively. It should be understood that the floor cells 10 of the present invention are not limited to being square as in fig. 1, and other shapes such as hexagonal may be used.
Preferably, the second end surface 23 is a horizontal end surface, so as to increase the contact surface between the honeycomb substrate and the workpiece, and avoid scratching. Considering that the length of the grid wall 20 is typically greater than 1cm, i.e. the length of the second end surface 23 is typically greater than 1cm, the width of the second end surface 23 can be set smaller, for example, the width of the second end surface 23 is 0.2 mm.
More preferably, the second end face 23 is an arc-shaped end face, and the abrasion of the honeycomb bottom plate to the workpiece can also be effectively reduced by combining the set length of the grid walls 20.
In some examples, the included angles A and A' range from 45 degrees to 80 degrees. Theoretically, when the included angle a is 45 °, the laser beam irradiated from right above is reflected to be a horizontal beam and is emitted to the opposite grid wall 20 on the other side, and then is reflected by the grid wall 20 on the other side and returns to the workpiece. The energy of the laser beam after the cutting of the workpiece, the air transmission and the two reflections is greatly attenuated, and the workpiece is difficult to be further damaged, so that the aim of protecting the workpiece is fulfilled.
Further, the values of the included angles a and a' are related to the following parameters:
setting the bottom plate unit cells to be square, and calculating to obtain values of included angles A and A' by combining the length-width ratio of the grid walls and the stress characteristics of the grid walls:
where h is the thickness of the cell walls, w is the width of the cell walls and the height of the honeycomb floor, l is the length of the cell walls and the side length of the floor cells (assuming that the floor cells have a cross-section in the shape of an equilateral rectangle), c is a scaling factor, influenced by the aspect ratio of the cell walls and the maximum horizontal force that the cell walls need to withstand, and F is the thickness of the cell walls, the width of the cell walls, and the height of the honeycomb floormaxIs the maximum horizontal force, F, that the wall of the cell needs to withstandmaxIs related to the self-weight of the grid wall, the maximum friction force exerted on the grid wall by the workpiece to be machined.
Galvanized iron sheet (with the density of 7.86 g/cm) is usually selected at present for economic cost performance of enterprises3) Is a bottom plate material.
Assuming that the self-gravity to be borne by each grid wall is G, the thickness of the grid wall is 2-4 mm, and the length and the width are 1cm, G is 1X 0.4X 7.86X 9.8X 30N, or G is 1X 0.2X 7.86X 9.8X 15N. It follows that the dead weight of the cell walls and the dead weight of the honeycomb floor consisting of a large number of cell walls are not negligible.
In some examples, to simplify the calculation process and to sufficiently maintain the stability of the cell walls, in the case of a light workpiece to be processed (e.g., a workpiece to be processed whose weight is less than or equal to about the self-weight of the honeycomb base), the maximum horizontal force F that the cell walls may bear is set equal to the self-weight G, thereby simplifying the influencing parameter to the aspect ratio of the cell walls.
From the foregoing, the length, width and thickness of the mesh walls are balanced against one another. As a preferred example, the width of the mesh wall varies from one half of its length to the same length, and the tip portion of the mesh wall can be regarded as an isosceles triangle, and a' have the same included angle and are symmetrical in opposite directions. Practice proves that when the length and the width of the grid wall are equal, stress balance of the grid wall can be well maintained when the inclined edge of the isosceles triangle is equal to 3 times of the base, the base of the isosceles triangle is b, the difference value of the thickness h minus the length of the second end face is obtained, the inclined edge is 3b, cosA is 1/6, and angle a is 80 degrees. When the width of the grid wall is equal to one half of the length of the grid wall, the weight of the honeycomb bottom plate is reduced due to the increase of the side length of the unit grid, but the self-gravity to be born by the single grid wall is increased due to the great reduction of the arrangement density of the grid wall. In order to provide more supporting force, the value of the included angle needs to be reduced, the influence of the laser reflection angle is comprehensively considered, the inclined side of the isosceles triangle is set to be approximately equal to 0.7 of the base side, at the moment, cosA is 5/7, and angle a is approximately equal to 45 degrees.
In the case that the workpiece to be processed is heavy (for example, the weight of the workpiece to be processed is several times or ten times of the self weight of the honeycomb base plate) and the control on the laser reflection beam is more strict, the honeycomb base plate can be manufactured by the following method, which specifically comprises the following steps:
and S1, determining the size parameters of the honeycomb bottom plate according to the physical parameters of the workpiece to be processed.
And S2, determining the thickness of the iron sheet material for processing the honeycomb bottom plate and the size parameters of the grid walls including the width of the iron sheet for sharpening according to the size parameters of the honeycomb bottom plate and the processing technology.
And S3, calculating the maximum friction force possibly borne by the grid wall according to the gravity of the workpiece to be processed.
And S4, constructing a grid wall stress model, carrying out layering processing on the grid wall, and calculating stress data of each layer.
And S5, calculating the minimum thickness of each layer by combining the rigidity parameter and the deformation parameter of the iron sheet material.
And S6, calculating to obtain values of the included angles A and A ', if the value is greater than or equal to 45 degrees, taking the calculated value as the value of the final included angles A and A ', otherwise, taking 45 degrees as the value of the final included angles A and A ', and recalculating the thickness of the iron sheet material or the size parameter of the grid wall.
S7, selecting processing parameters of the iron sheet material and the honeycomb bottom plate, sharpening the iron sheet material according to the values of the final included angles A and A', enabling the thicknesses of the sharpened iron sheet material to be larger than or equal to the corresponding minimum thickness, and manufacturing the honeycomb bottom plate by adopting the processed iron sheet material.

Loading: firstly, extending the supporting rod to enable the bearing platform to be positioned above the honeycomb bottom plate, then moving the workpiece to be processed to the bearing platform, and jointly supporting the workpiece by the N bearing platforms, wherein a gap is formed between the workpiece to be processed and the upper surface of the honeycomb bottom plate and the workpiece is not contacted; after the position of the workpiece is adjusted, the supporting rod begins to retract, and when the supporting rod retracts, the bearing platform carries the workpiece to be processed to vertically descend until the workpiece is connected with the honeycomb bottom plate, and then the honeycomb bottom plate supports the workpiece; the bracing piece further contracts, makes bearing platform and the work piece separation of treating processing and continue to descend and accomodate to the recess in completely, accomplishes the process of going up.

This approach is particularly useful for workpieces that are heavy or have a high coefficient of friction.
