Description

Flexible support for laser cutting platform

Technical Field

The utility model relates to a laser cutting technical field specifically is flexible support for laser cutting platform.

Background

In laser cutting, a workpiece is heated by a high-energy-density laser beam, the temperature of the workpiece is rapidly increased, the boiling point of a material is reached in a very short time, the material starts to vaporize, steam is sprayed out, and a notch is formed in the material at the same time of spraying. As a novel thermal cutting technology, laser cutting has the advantages of high cutting speed, high production efficiency, good quality of cut end faces, small heat affected zone and environmental protection, has become one of the main metal plate cutting modes, and is increasingly widely applied.

At present, the platform that is used for supporting panel during laser cutting is for preventing to be burnt out by laser ablation after by cutting panel, adopts a plurality of top surfaces to constitute for the mode that the stereoplasm backup pad of wave is put immediately to the wave top surface of backup pad contacts with being cut panel, can very big reduction by the area of laser ablation, also makes things convenient for local change simultaneously, need not to change whole platform. In this way, when supporting thin plates or high-demand products, such as mirror plates, automobile covering plates, thin copper plates, thin aluminum plates, etc., the wavy hard supporting plates are prone to indentation and scratch on the surface of the products. In order to solve the problems, the surface of a product is generally coated at present, scratches on the surface of the product are further reduced, coating is carried out on each product, the cost is increased, a coating process is added, the processing efficiency is reduced, and the product is coated with a film, and then the film is coked to cause black edges when laser cutting is carried out, so that the product quality and the attractiveness are affected.

Further, the supporting plate is connected with the side plate through a bolt.

Has the advantages that: and the bolt connection is adopted, so that the structure is simple, the installation is convenient, and the economy and the practicability are realized.

Furthermore, a cushion block is fixed between two adjacent supporting plates.

Has the advantages that: the cushion blocks are used for spacing the supporting plates, so that on one hand, a cutting gap can be reserved, the area ablated by laser is further reduced, and the service life is prolonged; on the other hand, the using amount of the supporting plate can be reduced under the condition of enough supporting force, so that the cost is further saved; after the interval is reserved between the backup pad, the cushion then has played the effect of supplementary firm backup pad, and the interval between the backup pad can be adjusted through the cushion of changing different thickness during the in-service use to be suitable for the support of different work pieces (the required holding power of different work pieces is different), enlarged application scope, improved the flexibility.

Furthermore, the cushion block is detachably connected with the side plate.

Has the advantages that: the cushion block is convenient to disassemble and replace.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a mounting groove 1, a support frame 2, a side plate 3, a support plate 4, a support unit 5 and a cushion block 6.

Example (b):

as shown in fig. 1, the flexible support for the laser cutting platform comprises a support frame 2 and a plurality of support units 5, only one support unit 5 is shown in fig. 1, each support unit 5 comprises two side plates 3 which are vertically arranged and parallel to each other, a plurality of support plates 4 are vertically arranged between the two side plates 3, the side plates 3 and the support plates 4 are connected together in a penetrating manner through bolts, the support plates 4 are all parallel to the side plates 3, the top surfaces of the support plates 4 are higher than the top surfaces of the side plates 3, and the top surfaces of the support plates 4 form a support surface for supporting a workpiece. Support element 5 demountable installation is on support frame 2, and is concrete, and 2 bilateral symmetry of support frame opens has a plurality of mounting grooves 1, and 5 both ends frames of support element are in mounting groove 1, and the bolt interlude is connected.

As shown in fig. 2, a cushion block 6 is further fixed between two adjacent support plates 4, the cushion block 6 is used for separating a gap between two adjacent support plates 4, and the cushion block 6 is inserted into the bolt. In this embodiment, the hardness of the side plate 3 is slightly greater than that of the support plate 4, and mainly plays a role in fixing the support plate 4, and the support plate 4 is made of a material with a small hardness, so that the top end of the support plate 4 can deform when being pressed. Specifically, the side plate 3 can be made of carbon steel or hard aluminum, the supporting plate 4 is selected according to the material of the workpiece, the hardness of the supporting plate is smaller than that of the workpiece, if the workpiece is made of steel, soft aluminum can be selected, and if the workpiece is made of aluminum, silicon steel can be selected.

In actual application, a proper number of supporting units 5 are selected according to the size of a workpiece to form a supporting platform, the workpiece is placed on the supporting platform, and the workpiece is cut by a laser cutting machine. When the work piece was placed on supporting platform, the top and the work piece contact of backup pad 4, because the top of backup pad 4 is the plane, compare the board of wave shape among the prior art, the utility model discloses change discrete point contact into the face contact, increased the area of contact of backup pad 4 with the work piece, can effectual dispersion pressure to reduce the indentation, improve the surface quality of product.

After the workpiece is placed on the supporting plate 4, the top of the supporting plate 4 can be deformed and slightly bent downwards (i.e. the state shown in fig. 2), so that flexible support is realized, the indentation and the scratch of the workpiece are further reduced, and the surface quality of the workpiece is improved. In addition, because the supporting plate 4 is deformed, the dropped slag can drop to the side surface of the supporting plate 4 or drop along the side surface of the supporting plate 4 during cutting, and the amount of the slag retained at the top end of the supporting plate 4 is reduced, so that the conditions that the slag forms convex points after being cooled and hardened to cause indentation and scratch on subsequent workpieces are effectively reduced, the generation of the indentation and scratch on the workpieces is further reduced, and the surface quality of the workpieces is improved; in actual application, the workpiece does not need to be coated, so that the coating process and time are saved, the processing efficiency is improved, and the influence on the product quality caused by the formation of black edges due to film coking is avoided.

In the practical application process, the quantity of the supporting plates 4 and the distance between the supporting plates 4 can be changed according to the supporting force required by the workpiece, the quantity of the supporting plates 4 is reasonably controlled while enough supporting force is provided for the workpiece, and the cost can be effectively reduced. Wherein the spacing of the support plates 4 can be achieved by replacing the spacers 6 of different thicknesses.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that, for the person skilled in the art, without departing from the structure of the invention, several variants and modifications can be made, which should also be regarded as the scope of protection of the invention, which will not affect the effectiveness of the implementation of the invention and the utility of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
