Description

Technical Field

[0001] The utility model relates to a supporting device in the process of gas cutting or laser cutting, in particular to a cutting workbench. Background Art

[0002] When cutting a metal part, the metal part needs to be placed on a cutting workbench, and then the metal part is cut by a laser cutting gun or a gas cutting gun.

[0003] The existing cutting workbench includes a pedestal, and a plurality of support plates arranged at intervals in the front-back direction are welded on the pedestal. During use, the metal part to be cut is placed on the support plates. The support plates have a small contact area with the metal part, so the corresponding cutting requirements can be met.

[0004] The problem in the prior art is that when cutting a metal part with a laser cutting gun or a gas cutting gun, molten cutting slag will be generated. The cutting slag will flow onto the support plates and then solidify again. After using for a period of time, a large amount of cutting slag will solidify on the support plates, which will affect the normal cutting process. At this time, the cutting plates need to be replaced. In the prior art, the entire cutting plate needs to be removed for replacement, and the cutting plate is welded to the pedestal, so the repair and replacement of the cutting plate are very inconvenient. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cutting workbench with a cutting plate that is convenient for repair and replacement.

[0006] To solve the above technical problems, the technical solution of a cutting workbench in the utility model is as follows:

[0007] A cutting workbench includes a pedestal, and a plurality of support plates arranged at intervals in the front-back direction are provided on the pedestal. Each support plate includes a lower support plate fixedly arranged on the pedestal and an upper support plate separately arranged from the lower support plate. The upper end of the upper support plate has a plurality of support protrusions arranged at intervals in the left-right direction. A support plate stop structure for restricting the left-right movement of the upper support plate is provided on the lower support plate or the pedestal. The upper support plate and the lower support plate are connected by a card slot that is engaged in the up-down direction to restrict the front-back movement of the upper support plate relative to the lower support plate.

[0008] Further, front side connecting plates and rear side connecting plates are fixed on the front and rear sides of the upper support plate. The card slot is formed between the front side connecting plate and the rear side connecting plate. The front side connecting plate and the rear side connecting plate are located on the front and rear sides of the lower support plate.

[0009] Further, two card slots are corresponding to each upper support plate, and the two card slots are arranged at intervals in the left-right direction.

[0010] Further, the front connecting plate and the rear connecting plate are fixedly connected to the upper support plate by rivets.

[0011] Further, the support plate blocking structure includes a support plate left protrusion provided at the left end of the lower support plate and a support plate right protrusion provided at the right end of the lower support plate.

[0012] Further, a triangular groove with a gradually narrowing width from top to bottom is formed between adjacent support protrusions of the same upper support plate, and the top of each support protrusion is a cylindrical structure with an axis extending in the front-rear direction for contact and cooperation with the bottom of the metal part to be cut.

[0013] The beneficial effects of the present utility model are as follows: When the present utility model is in use, each support plate includes a separately provided upper support plate and a lower support plate. The upper support plate is snap-connected to the lower support plate through a card slot, so that the upper support plate cannot move back and forth relative to the lower support plate. By blocking the upper support plate through the support plate blocking structure, the left and right movement of the upper support plate can be restricted, thus realizing the positioning of the upper support plate. Place the metal part to be cut on the support protrusions of the upper support plate, and then the cutting operation can be performed on the upper support plate. After using for a period of time, the cutting slag solidifies on the upper support plate. Just move the upper support plate upward from the lower support plate from bottom to top, and then clean the upper support plate, or place a new upper support plate on the corresponding lower support plate from top to bottom to achieve the repair and replacement of the upper support plate, which is very convenient.

[0021] For the convenience of understanding the present invention, the present invention will be described in more detail below in conjunction with the drawings and specific embodiments. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present invention more thorough and comprehensive.

[0022] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0023] An embodiment of a cutting workbench in the present invention is as Figures 1 to 5 shown:

[0024] It includes a base 1, and a plurality of support plates 2 arranged at intervals in the front-rear direction are provided on the base 1. Each support plate 2 includes a lower side support plate 3 and an upper side support plate 4 separately provided from the lower side support plate 3. The lower side support plate 3 is fixed on the base 1, and the upper end of the upper side support plate 4 has a plurality of support protrusions arranged at intervals in the left-right direction. In this embodiment, a triangular groove 10 with a gradually narrowing width from top to bottom is formed between adjacent support protrusions of the same upper side support plate. The top of each support protrusion is a cylindrical structure 9 with an axis extending in the front-rear direction for contact and cooperation with the bottom of the metal part to be cut. During use, the metal part to be cut is placed on the upper end of the corresponding cylindrical structure, and the cylindrical structure 9 is in line contact with the bottom of the metal part, which can reduce the contact area between the metal part and the support plate and reduce the probability of the support plate being cut. A bottom groove for avoiding stress concentration is provided at the bottom of the triangular groove.

[0025] A support plate stop structure for restricting the left-right movement of the upper side support plate is provided on the lower side support plate (or the base). In this embodiment, the support plate stop structure includes a left convex 5 of the support plate provided at the left end of the lower side support plate and a right convex 6 of the support plate provided at the right end of the lower side support plate. During use, the upper side support plate 4 is placed between the left convex 5 of the support plate and the right convex 6 of the support plate, thereby restricting the left-right movement of the upper side support plate.

[0026] The upper support plate and the lower support plate are connected by card slots that are engaged with each other in the up-and-down direction, thereby restricting the front-back movement of the upper support plate relative to the lower support plate. In this embodiment, there are two card slots corresponding to each upper support plate, and the two card slots are arranged at intervals left and right. The front connecting plate 12 and the rear connecting plate 7 are fixed to the front and rear sides of the upper support plate. The card slots are formed between the front connecting plate 12 and the rear connecting plate 7. The front connecting plate 12 and the rear connecting plate 7 are located on the front and rear sides of the lower support plate. The upper ends of the front connecting plate and the rear connecting plate are fixedly connected to the upper support plate by rivets 8.

[0027] In the present utility model, when there is a lot of cutting slag adhered to the upper support plate, the upper support plate can be easily taken out from bottom to top to clean the cutting slag on the upper support plate. After the cleaning is completed, the upper support plate can be placed back on the lower support plate from top to bottom; of course, it is also possible to place a new upper support plate on the lower support plate from top to bottom during the process of taking out the upper support plate for cleaning. The card slots are provided on the upper support plate, so the slot openings face downward, which can reduce the entry of cutting slag into the card slots. In other embodiments of the present utility model, the card slots can also be provided on the lower support plate. At this time, the slot openings of the card slots face upward.
